Abstract
Femoral fracture is trauma with high mortality rate. Incidence of femoral fractures in America is approximately 13 cases per 100,000 people per year. In Indonesia, it is reported that the incidence of fractures every year is 11.10 cases per 1,000 people per year, with an incidence of 11.67 cases per 1,000 people per year in men and 10.65 cases per 1,000 people per year in women. Long bone fracture cases frequently related to missing bone segments, that can disrupted the bone healing. Incidence of long bone fracture with defect reported about 13,9%. The process of defect fracture healing requires internal and external mechanical stimulation, external stimulation can be stimulated using low-intensity pulsed ultrasounds. The positive effects of ultrasound therapy (LIPUS) on accelerating bone healing have been demonstrated in several studies. Clinical studies have shown a significant positive effect from LIPUS in the treatment of non-union fractures and accelerated fracture repair compared to fractures treated with placebo of 38%. The purpose of this study was to determine the effectiveness of LIPUS on healing of defect femoral fractures in rabbit post ORIF plate and screw based on radiological measurements. This study is a comparative, unpaired laboratory experimental study with two treatment groups and one control group. Treatment group consist of group I that was given LIPUS 30 mW/cm2 for 10 minutes per day and Group II 30 mW/cm2 for 20 minutes per day, Group III without LIPUS treatment as control group. Radiological assessment was performed to assess callus formation based on the Tiedemann score. After that data is collected, data editing, coding, entry were carried out and analyzed statistically. There were significant differences between treatment group and control group towards callus diameter formation, between group I, II and control with mean of Tiedemann in each group 97.76; 169.83; 76.88; with p value < 0.05. LIPUS can enhance fracture healing in rabbit femur defect based on radiography measurement.

Abstract
Background Fractures are among the most frequent type of injuries in patients exposed to traumatic injury. There is increasing evidence that exposure to electromagnetic radiation can affect human health. Electromagnetic radiation stimulation is known to affect biological activity on related to fracture healing. Low-frequency electromagnetic radiation exposure has been utilized widely for supporting therapy to enhance fracture healing. This study aimed to evaluate the effects of exposure to electromagnetic radiation at a frequency of 2600 MHz (the frequency of fourth-generation cellular phones) on the healing of femur fractures in rats treated with ORIF K-wire. Methods. The study was carried out with 22 mature male Wistar rats. Femur osteotomy and fixation with open intramedullary wire were performed on all rats. The rats were preoperatively divided into two groups using simple random sampling, –a control group and an experimental group. Only the experimental group was exposed to electromagnetic radiation at a frequency of 2600 MHz for 30 minutes daily, five days per week for 2 weeks. Histopathological tests were conducted 2 weeks after the operation. Result. The Mann Whitney test score showed fracture healing was statistically significantly higher in the experimental group than in the control group (p<0.05, 3.55±0.69- and 5.91±0.83, respectively). Discussions. The thermal and non-thermal effects of electromagnetic radiation exposure have been shown to promote the proliferation phase of fracture healing due to radiation hormesis. Conclusions. High-frequency electromagnetic radiation exposure at 2600 MHz enhances the proliferation phase of the femur fracture healing process.

Abstract
Abstract— Indonesia is a state of law as explained in article 1 paragraph 3 of the UUD 1945 Constitution which stipulates that the Republic of Indonesia is a state based on law (Rechstaat). As a constitutional state, it is necessary to uphold good human rights, certain groups as well as individuals, vulnarable people, etc. One of which is principle of equal treatment before law of this country described in Article 3 paragraph 2 of Law No. 39 of 1999 concerning Human Rights and Article 28 D paragraph 1 .UUD 1945. But in applying the principle of equal treatment before law, there are specific criminal acts that are not in accordance with these principles related to the period of detention, especially in criminal acts of terrorism where the period of detention from the level of investigation, prosecution and examination in court proceedings is much longer than other special criminal acts, namely 290 days which are specifically regulated in Law No. 5 of 2018 concerning amendments to Law Number 15 of 2003 concerning stipulation of regulations Government In lieu of Law Number 1 of 2002 Regarding Eradication of the Criminal Act of Terrorism into Law. While other specific criminal acts include corruption, money laundering and narcotics crime related to the period of detention from the level of investigation, prosecution and examination in a court of law which is regulated based on the Criminal Procedure Code which has a shorter period of 200 days. Based on this there are differences related to the period of detention between terrorism and other specific criminal acts. Therefore it needs to be questioned related to the application of the principle of equality before the law in the criminal act of terrorism.

Abstract—Children are the next generation of the nation which is very important in a country. For this reason, children must be able to grow and develop as well as they can. Due to several factors, such as poverty, broken families, divorced parents, in their growth and development, children do not always get the best that is expected, sometimes children whose conditions are ready to help follow up. Handling cases of children who are in conflict with the law through the legal process is finished up in prison. This of course can damage the future because it creates a negative stigma in the community. For this reason, Law Number 11 of 2012 concerning the Juvenile Justice System was approved, which was approved by diversion, namely the transfer of approval of child cases from court proceedings that leave court proceedings. Article 7 paragraph (2) of the Law Number 11 of 2012 must meet the requirements, namely (1) the crime of safety under 7 (seven) years, and (2) does not constitute a repeat of the crime. In addition, there must be agreement or agreement with the victim and / or responsibility. The handling of cases of children in conflict with the law through diversion is carried out using restorative justice, namely by presenting children and families, victims and defenders, community leaders, social counselors, social services, social workers, and other parties Improvements to repairs and not retaliation.

Abstract
Indonesia is Maritime nation. The number of a small island is one of the diversity possessed by Indonesia beside the diversity of culture and ethnicity. Indonesians who live in coastel areas in their daily lives can not be separated from their dependence on coastal resources due to the livelihoods of their inhabitans who depend on the sea. Their livelihood is sourced from the sea, so they choose to live in coastal areas. The potential and diverse natural resources in coastal areas become an attraction for the community to meet their daily needs, so that coastal settlements are formed that vary according to the level of community life. The increasing number of Indonesian people living in coastal areas is their reason to build floating houses in the coastal area where these floating houses are a place to live and gather a family. The house is a place where all family members stay and do activities that become daily routine. Based on the wisdom and customs of the surroundings, the floating houses, which generally belong to fishing communities, were established on their own initiative. So that its establishment is not based on permission from the government, and does not have the basis of rights like houses in general on the mainland. Whereas according to the Law of the Republic of Indonesia Number 28 Year 2009 concerning Regional Taxes and Regional Levies Article 1 paragraph (39) intended for construction is technical construction which is planted or permanently attached to land and / or inland and / or sea waters. The existence of a legal vacuum regarding floating houses causes community unrest towards the legitimacy of the floating houses themselves when in fact the indigenous people themselves have built floating houses long before the Basic Agrarian Law was made.

Abstract
Village recognition is needed for the village in an effort to the establishment of unity of the law that has authority and is autonomous. With the recognition of the village, the existence of the village will continue to be recognized and respected.In realizing the existence and recognition of villages, there are still weaknesses in village regarding recognition. Based on this weakness, in 2014, Law No. 6 of 2014 was enacted, namely the Village Law which has been running for 5 years until now.in the realization of the implementation of the Village Law there are many problems in the application of authority in the village community. To overcome these problems, it is necessary to have the role of the village as a sector amplifier to support the village law. these roles include village officials, sub-districts, DPMD and organizations.Therefore, to support the implementation of the village law not only strengthen the village but also strengthen several sectors that can support the village to run its authority.

Abstract
Broiler chickens is a type of chicken that has a fast growth rate and requires large amounts of nutrients absorbed from feed. Absorption of nutrients in the feed requires the function of a good digestive tract to optimize the digestive process. The digestive process also requires optimal time in absorption of feed nutrients called the digesta rate. The purpose of this study was to determine the right level of addition aloe vera powder to the length of digestive tract and the rate of digesta broiler. This study used a completely randomized design with 4 treatments and 4 replications, namely P0: feed without aloe vera powder (control), P1: feed + 0.075% aloe vera powder, P2: feed + 0,1% aloe vera powder and P3: feed + 0,125% aloe vera powder. The treatment had a significant effect on the jejenum length and digesta rate. But it had no significant effect on the duodenum length and the ileum lenght. The jejenum length was significantly different in treatment P1 of 85.50 cm and P3 of 83.75 cm when compared to treatment P0 of 73.25 cm. Digesta rate was significantly different from the P3 treatment was 259 minutes when compared to the control treatment (P0) 200 minutes. The results of the study showed that the addition of aloe vera powder with the best level was at the level of 0.125% (P3) which optimizes the jejenum length and the rate of digesta broiler. The conclusion is that the addition of aloe vera powder with a level of 0.125% in broiler feed can optimize the length of jejenum and increase the rate of digestion

Abstract
Population growth in sub-urban areas in developing countries is very fast in excess of the ability to provide public facilities. Clean water infrastructure has a challenge where most of the water sources are taken from unsustainable groundwater. Intake of ground water results in various environmental problems such as a decrease in groundwater level and landsubsidence. The distribution system has a high level of leakage, the service has not been continuous 24 hours, and very low pressure is still often found in various locations. The research explains the strategy in changing groundwater sources into surface water sources. The optimization of the drinking water distribution network is carried out by evaluating the network system using epanet software and then doing the rehabilitation design and network development according to future developments. The results of the analysis of the epanet model show that the use of deep well pump systems directly distributed to customers results in inefficiencies from pressure. Access to safe drinking water needs to be prepared first from the availability of raw water, treatment units to the distribution network. The construction of clean water transmission pipeline system is prepared to go into a different zoning from the initial network. Zoning pumping network systems will increase pressure significantly and reduce leakage through control.

Abstract
Indonesia is one of the major clove producers in the world. The majority of clove used as the main ingredient of clove cigarette (kretek) industry. The decreasing trend of clove cigarettes demands caused alternative industries development besides the clove cigarette industry are needed. The purposes of this paper are to analyze policies related to Indonesian cloves, analyze the development of alternative clove industries and their challenges as a green industry in the future. This research is a literature study. Government policies related to the clove industry are still focused on efforts to fulfill cloves for the cigarettes industry and have not yet led to the development of other cloves industry besides cigarettes industry. This has led to the development of other manufacturing industries such as essential oil as a potential export commodity that has not received serious attention from the government. The development of cloves agro-industry is expected to not only encourage the development of green industry, increase export values but also improve the welfare of farmers.

Abstract
Introduction and Research Problem PT XYZ needs to design and implement risk management. One of the urgency for designing and implementing risk management system is because the soul of the parent companys business is in the construction field and wants to diversify its business into new business fields as energy investments that entrusted to PT XYZ. New business fields in the energy sector will certainly be faced with the high risks. Coupled with minimal experience makes the risk faced will be even higher. The need for the design and implementation of risk management at PT XYZ is also indicated by the occurrence of cost overrun in current projects. In carrying out each project, PT XYZ must pay a pre-development cost whose value is quite high. However, after PT XYZ spent the costs, the planned project may not be able to be proceed to the next stages. Therefore, PT XYZ has potential to pay sunk costs. Design and implementation of the risk management system is expected to make the usage of project pre-development costs will be more efficient. Methods The design of risk management systems in this study uses the ISO 31000: 2018 approach. To find out the current implementation of risk management at PT XYZ, an assessment of the risk maturity level that refers to the Chapman model (2011) was conducted. Furthermore, the risk management system then implemented by PT XYZ which includes several stages. The external context determination stage uses the PESTEL analysis and stakeholder analysis while the internal context determination stage uses the 7s McKinsey analysis. The Risk Breakdown Structure method through Work Breakdown Structure is used to identify the risks. In addition, root cause analysis be used to compose risk treatment plans. Results and findings This study-s result are risk management system design such as: risk management policy, proposed organizational structure, SOP and risk management processes templates that include communication and consultancy; determination of the scope, context and criteria; risk assessment; risk evaluation; risk treatment; monitoring and review; recording and reporting. The risk maturity level assessment shows that currently PT XYZ is at the basic level. In implementation of risk management design, the scope of risk management process is limited to PT XYZ and has not been integrated with its subsidiaries. From the process, 128 risks in PT XYZ have been identified, consisting of 59.4% strategic risks; 32.0% financial risk; 4.7% HR risk; 1.6% reputation risk; 1.6% legal risk; and 0.8% operational risk. In addition, the result of the risk evaluation shows that PT XYZ has 8% extreme risk. Conclusions, implications and significance The risk management system has been designed at PT XYZ. The risk maturity level of PT XYZ shows that the risk management system is designed as an effort to improve the business. Beside, risk treatment plans are composed to reduce the level of likelihood and / or level of impact of ex

Abstract
INTRODUCTION Environmental sustainability around Rawa pening has changed due to the density of water hyacinth weeds. Water hyacinth experiences very rapid growth due to eutrophication. Eutrophication is the presence of excess nutrients in the form of nitrate and phosphate which are sourced from agricultural activities, fisheries, settlements and livestock from the land around the lake. This is what causes the growth of water hyacinth very quickly, in a short time to multiply1. To control and utilize water hyacinth, one of them is by using pyrolysis technology. Biomass pyrolysis is carried out at high temperatures. Pyrolysis comes from two words namely pyro and lysis, which means decomposition. Biomass pyrolysis is usually carried out at temperatures above 150 °C. Pyrolysis is divided into two based on the level of the process, namely primary and secondary. Primary pyrolysis takes place at temperatures less than 600 °C. The main result is carbon or charcoal. Primary pyrolysis is further divided into two namely fast and slow pyrolysis primary. Slow primary pyrolysis occurs at 150-300 °C heating. The results obtained in this condition are carbon, water, carbon monoxide and carbon dioxide. Rapid primary pyrolysis that occurs at temperatures over 300 °C will produce gas, carbon and steam2. Secondary pyrolysis is that occurs at temperatures above 600 °C. at this temperature the result is carbon monoxide, hydrogen, hydrocarbons and Tar around 1-6% 3.4. The purpose of this study was to determine the chemical composition of Rawapenings water hyacinth and study the effect of pyrolysis time on the volume of liquid smoke products. The stages of the research carried out are as follows: Water hyacinth is cut into pieces with a size of about 2-3 cm and then a pyrolisator is added. A total of 700 g of water hyacinth sample into the pyrolysator is stainless steel. The dependent variable in this study is the type of water hyacinth that has been dried in the sun. Water hyacinth is taken from Rawapening. In testing the chemical composition observed is the content of hemicellulose, cellullose and lignin. The independent variables are at temperatures of 117 °C, 400 °C and 683 °C. The volume of liquid smoke that comes out after passing through the condenser is recorded in volume. RESULTS AND DISCUSSION The results of observations of the chemical composition of the water hyacinth Rawapening can be seen in Figure (a). The chemical composition of the water hyacinth that was observed to have hemicellulose, cellulose and lignin content respectively was 36, 21 and 7 percent dry weight. In the picture also explained the chemical composition of other materials, namely wood kers, soft wood, coconut shell and cassava stems. So it can be believed that the results obtained from observations made in the integrated laboratory Undip show that water hyacinth can be used as raw material for liquid smoke.

Abstract
Background: Rice (Oryza sativa. L) is the main commodity of Indonesian food crops and become a staple food for the community. Black rice has high anthocyanin content, so it is very beneficial for the community. The relatively long age of black rice and low productivity are weaknesses that must be overcome. The development of black rice varieties is needed to assemble new plants that have a short life and high productivity. Plant assembly is strongly influenced by the level of plant kinship. Plant assembly is often done incorrectly due to close kinship, so diversity analysis is needed so that the development of black rice varieties is appropriate. Phylogenetic analysis describes genetic distance or differences between individuals in an organism or species. Phylogenic analysis can be carried out using morphological, physiological and molecular characteristics. Morphological characteristics are based on differences in the morphological characteristics of each plant. Molecular identification use RAPD (Random Amplified Polymorphic DNA) based on DNA sequences that are homologous with a single short (10-12 base) oligonucleotide sequence. Molecular characters are based on genotypic characters, namely by looking at the different patterns of DNA bands that owned by plants. Aims: To determine the level of kinship and diversity in 10 varieties of black rice (Oryza sativa L.) based on morphological and molecular identification. Materials and Methods: In this study, we determinated the level of kindship of 10 varieties of black rice included Hitam Purbalingga, Hitam Purwekerto, Hitam Lumajang, Hitam Blitar, Hitam Bantul, Hitam Banjarnegara, Hitam Toraja, Hitam Melik, Pari Ireng, and Here Lahok/Timor Leste based on morphological and molecular identification. Morphological identification uses 7 variables i.e plant height, number of productive tillers, weight of 100 seeds, shape of grain, colour of grain, colour of rice age of flowering and age of harvest. The analysis results realized in the form of a dendogram. Molecular identification using RAPD marker with 9 primers included OPB-01, OPB-04, OPB-08, OPB-10, OPB-11, OPB12,OPB-13, OPB-17 and OPB-18. The DNA band profile translated into binary data with the provision of a value of 0 for no band and 1 for the presence of DNA bands in certain fragments. Both of data analysed into cluster using NTSYSpc software with DIST coefficient for morphological data and Jaccard-s Index for molecular data. The analysis results are realized in the form of dendogram and genetic similarity values. Results: Dendrogram of morphological data showed in 2 clusters, 2 groups and 2 subgroups. Cluster I was accopied by Hare Lahok and Hitam Purwekerto. Cluster II devided into 2 groups. First group include Hitam Blitar and second group include Hitam Melik, Pari Ireng, Hitam Bantul, Hitam Lumajang, Hitam Toraja, Hitam Purbalingga. Molecular kinship analysis used to determine the level of genetic similarity of 10 black rice vari

Abstract
Background: Anther culture is a tissue culture technique that uses pollen to produce plants. Anther culture shortens the acquisition time of pure lines from 6-8 generations of plants to 1-2 generations [1]. The success of tissue culture can be seen by the high regeneration power of callus that is formed. Factors that can affect one of them is the difference in nutrition and growth regulators given. The addition of growth regulators in the form of IAA and Kinetin is expected to be able to handle the problems that occur in the regeneration process of anther callus. This research uses combination media A1: 0 ppm, A2: 1 ppm, and A3: 2 ppm. The second factor is the concentration of Kinetin with 4 levels B1: 1 ppm, B2: 1.5 ppm, B3: 2 ppm, and B4: 2.5 ppm. Observation variables include 1) Green Spot, 2) Brown Callus, 3) Plantlet, 4) Root. The results showed that the treatment of 2 ppm IAA + 2.5 ppm Kinetin gave a good response of anther callus regeneration, 12.5% plantlets formed and appeared when the callus was 30 days marked by budding, 62.5 % green spot formed; 0% browncallus, 12.5% plantlet; and 50% rooted callus. Aims: To obtained the right concentration of IAA and Kinetin for the regeneration of black rice plant anther callus in vitro. Materials and Methods: The materials used in this study were black rice anther callus from previous studies; 0.4gr / 100mL N6; 0.3gr / 100mL Phytagel; 3% sucrose; 0.05gr / 100mL glutamine; IAA and Kinetin, 70% alcohol; NaOH; HCl; and aquadest. Callus subculture the calli of 1-2 mm diameter with criteria callus friable to N6 regeneration media which includes a combination of IAA (0; 1; 2) ppm, Kinetin (1; 1.5; 2; 2,5 ) ppm. The regeneration callus that had been transferred to the regeneration media was incubated in a sterile room in a room without light for 7 days for a total of 8 calluses per bottle. The regeneration callus was then placed in a no-light condition (dark room) for 7 days. After that, transferred to a room with light for 16 h at 28±2ºC and light intensity 1500-1600 lux until a plantlet appears. Subcultures need to be done further because at the age of ± 14-21 days the callus that has been subcultured previously shows a change in size and if it takes too long the callus will turn brown and the regeneration power of the callus decreases. Results: The anther callus used in this study was an induction callus that was produced from a previous study, Bantul black rice variety using MS induction media; 0.5 ppm 2,4-D; 2.5 ppm NAA; and 0.5 ppm Kinetin. Callus regeneration required higher cytokinin concentrations compared to auxin [1]. Each increase in the concentration of cytokinins is able to show a tendency for the appearance of callus, shoots, and leaves more quickly, and plays an important role in the regeneration of the callus used [2].

Abstract
Heavy metals are metallic elements with high molecular weight and these substituents are toxic to living things even at low levels. Heavy metal pollution is very harmful to environment, especially for water-rich areas. These heavy metal pollutions originate from the industrial wastes that are dumped into the river. In this study, the concentration of heavy metals is decreased by using ozonation which uses the addition of hydrogen peroxide (H 2 O 2 ) to produce hydroxyl radicals (OH ● ) as a strong oxidizing agent. This method is known as Advanced Oxidation Process (AOP). The purpose of this research is to study the effects of the types of heavy metals and the process variables that are used such as the addition of H 2 O 2 temperature operation and pH condition. The study, show that iron, copper and manganese can be removed with AOP technology, the addition of H 2 O 2 , operating temperature and pH condition is able to accelerate the metals reduction. Background: Heavy metal pollutions are very dangerous to the environment especially on water body area. The heavy metal pollutants may harm either to human or to the ecosystem of the water itself (Supriharyono, 2000; Soemirat, 2005). Sastrawijaya, 2000 wrote that environment pollutions occur due to the addition of either living things, substances, energy or any other components to the environment which change the environment balance and decrease the quality of the environmental function. Many methods have been introduced to minimize the heavy metal pollutions such as sedimentation, filtration, adsorption and elimination using microbiology. Another promising technology in reducing heavy metal pollutions is using oxidation to get precipitated heavy metal then combined with filtration. Chlorine commonly used as the oxidation agent, however the present of other chlorination products in the water have also become another concern for human health. Nowadays, ozone has become a popular oxidation agent for removal impurities in water since ozone has strong oxidation ability either to organic or inorganic compounds. Ozone reactions are selective thus elimination of impurities may take longer times. The presence of ozone in water can produce stronger oxidant than ozone itself which is called as hydroxyl radical (OH • ). The reactions of hydroxyl radical or often called as Advanced Oxidation Process (AOP) are unselective and will provide faster reaction for heavy metal eliminations. Aims: In this research, the effect of hydrogen peroxide addition, pH and temperature operation of AOP were studied to obtain optimum operation condition for ferrous (Fe), cuprous (Cu) and manganese (Mn) heavy metal elimination. Materials and Methods: The standard ferrous, cuprous and manganese were purchased from Merck, Indonesia whilst hydrogen peroxide, sodium hydroxide, and nitric acid were purchased from Sakura Chemical, Indonesia. The ozone was generated from ozone generator (Ozontech, South Korea) whilst the

Abstract
Background: Conventional breeding to produce new high yielding varieties of cassava still dominates. Germplasm evaluation is the initial stage in conventional breeding, followed by hybridization to increase genetic diversity and clonal selection: single plant selection, single row selection, preliminary tests, and multilocation tests (Mariscal et al. 2001). In some areas, cassava is widely planted in upland dry land (600-1000 m above sea level). In the highlands, cassava requires a longer harvest time (aged 15 months to 24 months) in order to obtain high tuber yields. Noerwijati and Budiono (2015) reported that decreased tuber yield at 530 m asl was 32 %, while at 800 m asl was 86 %, compared to tuber yield at 80 m asl. lrikura et al (1979) have clearly stated that distinct genotypes are required for high altitude (mean temperature less than 22°C) compared to the lowland. Aims: to select high yielding cassava clones for use as selection material for adaptive cassava clones to medium-high altitude. Materials and Methods: The study was conducted in the Jambegede research station, Kepanjen sub-district, Malang, East Java, in 2018 planting season. The materials used in this study include 1016 cassava clones. Single plants from the crossing were planted in the field with a spacing of 100 cm x 80 cm. The design used is Augmented design with control varieties were several cross-parent genotypes, namely UK 1 Agritan, Litbang UK, Malang 4, Adira 4, Lokal Tlekung Ungu, and Gajah Ungu. Plants are fertilized with a dose of 225 kg Urea + 200 kg Phonska + 100 SP 36 per hectare. Fertilizer is given twice, namely 1 month and 3 month after planting. Weeding and repairs of ridges are carried out before fertilization. The parameters observed were fresh tuber yields and harvest index. The data obtained were analyzed using descriptive statistics and cluster analysis. Results: From 1016 individual in F1 cassava populations, have a tuber yield range of 0.20 kg to 9.20 kg with an average of 1.80 kg/plant. The average yield of each F1 family did not exceed the average of the control varieties. This is because the results of tubers in F1 population can not be maximized because the plants come from seeds, there are even F1 plants that do not produce tubers. However, there are F1 individuals that have tuber yield per plant above the average of control variety. The family that had the highest tuber yield per plant was the result of an open pollinated with female parent of the Kaspro clone. For the harvest index, the selected family has a harvest index above 0.5, which means they have good ability to produce tubers. From 1016 F1 individuals have a harvest index range of 0.25 to 0.96 with an average 0.75. These results are shown in the analysis cluster based on data on the average yield of tubers and harvest index of the F1 family which form five clusters. The control varieties form separate clusters from the average F1 family, with characteristics of tuber c

Abstract
Indonesia has many cultural heritages, which coming from various era. Commonly the protection of cultural heritages had focused on land-based site. Such as in Morotai, and the Java Sea which has numerous pre-Indonesian era up to world war II artefact such as Shipwreck, Airplane and its weapon which persisted underwater, and this artefact is essential for as historical document basis. However, the current condition of these artefacts is poorly damage, or on another hand almost disappear, and mostly caused by human hand. Indonesian Government shall realize the importance of underwater cultural heritage protection (herein referred to as UCH). UU No. 11 Tahun 2010 (Herein referred as Cultural Heritages Protection Act 2010) regarding cultural heritage site protection has no legal basis for this kind of protection. This paper will discuss the urgency of Indonesian Government ratified underwater cultural heritage convention to protect its underwater site, through comparison studies between countries has enacted their UCH national legislation. Ultimately this paper will make a suggestion which could be implemented in the further amendment of Cultural Heritages Protection Act 2010 or enacted specific UCH national legislation.

Abstract— Knowledge about psychotic disorders, having a positive attitude towards psychotic disorders and having knowledge about the care required is an important aspect for families caring for and handling psychotic disorders (family caregiver) to provide ongoing care. Psychoeducation can facilitate effective treatment and care through understanding family knowledge and attitudes related to caring for people with psychotics. This PKM was carried out in Sadangmekar village, Cisarua sub-district, West Bandung, for 7 family caregivers who treated family members who were experiencing psychotic disorders using alternative medicine or were left without treatment. Psychoeducation lasts for one day and uses methods of providing information (lectures), discussions, and watching videos. The results showed that after attending caregiver psychoeducation gained knowledge about the symptoms of the disorder (100%), the importance of medical and psychological treatment in managing the disorder (100%), the importance of adherence to treatment (100%) as well as the insight that the family has an important role in sustaining care (100%).

Abstract
Subjectivity in performance appraisal is almost inevitable. Subjectivity is defined as a perspective based on personal views or feelings about a thing. Eliminate subjectivity factors so that assessing objectively based on certain criteria is difficult to implement, whereas subjectivity causes unfair competition and giving rise to an uncompetitive environment. This research was conducted to reduce subjectivity in a performance appraisal using the Group Decision Support System with Simple Additive Weighting and Borda methods. Employee performance appraisal at PT. Krakatau Osaka Steel was the object of this research. The Group Decision Support System has selected the best employees from 59 employee samples taken by the Purposive Sampling method to resulted the 7 best employees according to the assessors with a Decision Support System, these results are then reselected to become the 3 best employees provided by the Group Decision Support System. The results of this study that Group Decision Support System can help evaluate employee performance.
