Abstract
The purpose of this study is to explore information related to the position of welfare state in fulfilling the basic needs of the people on water resources. This research raises legal issue concerning the lack of fulfillment of the constitutional mandate relating to the duty of state to fulfill the rights of the people in the field of water resources. This can be shown in several cases that most people still have difficulties accessing the water as a basic needs in their lives. In 2013, the Constitutional Court revoked Law Number 7 of 2004 concerning Water Resources and reactivated Law Number 11 of 1974 concerning Irrigation as a positive law in the field of water resources. This situation directly affected the management of water resources, especially related to policies that must be based on Law Number 11 of 1974. Substantially, the law also has many shortcomings and changes or replacements must be made in accordance with the people growth immediately. This type of research is normative juridical legal research, using statute approach and conceptual approach. The results of the study are expected to contribute ideas to the position of the welfare state in fulfilling the peoples basis on water resources.

Abstract
Our study about chromosomes imaging using DAPI stimulating light and soda lime glass microspheres whose diameters are spread from 35 μm to 120 μm shows that the magnification power of this system is 3 to 5 times. Images of chromosomes that colored with DAPI beneath the microspheres are observed have a size 3 to 4 times larger than the actual chromosomes. In addition, using microsphere lens approximation, the magnification power of chromosomes image without DAPI is 3.8 to 12.6 times whereas the magnification power of DAPI-stained chromosomes is 3.7 to 4.8. The spherical lens approximation does not show any variation of magnification even though the microsphere’s diameter is changed. Experimentally, there is an evident that microspheres can improve the performance of microscope in chromosomes imaging. This system is potential to engineer the optical microscope by applying photonics jet phenomenon.

Abstract
Environmental problems have occurred in the global, regional and national scope of both countries developed and developing countries. Environmental problems are not only problems of developed countries or industrialized countries including Indonesia. Efforts to overcome problems the environment in developing countries has no choice but to carry out development. Without development the standard of living of the people decreases and the environment will be increasingly damaged. Development must still be done without damaging and polluting the environment. Balance this must be done in order to preserve the environment. Indonesia has started pay attention to environmental management since 1972. Dispute resolution the environment through litigation has not produced much results. Dispute resolution conducted through non-litigation channels is based on the presumption that the settlement Environmental disputes through the litigation path result were very disappointing for victims of pollution environment. This study wants to conduct a study related to the implementation of Government Regulations Number 54 of 2000 concerning the Dispute Settlement Service Provider Institution Environment Outside the Court.

Abstract
Fossil fuels are the main fuel that is still used by the community. Along with the increasing population of Indonesia, the need for oil and gas fuel is also increasing. Therefore, oil and gas exploration activities are needed to obtain new economical reserves. A regional surface soil gas survey consisting of 300 sites were placed on approximately 1 km intervals using existing rivers, streams and navigable waterways within the onshore portion of the Boka area located in Mimika Regency in Papua for evaluation of the hydrocarbon potential. This soil gas data contains very large magnitude anomalies consisting of a unique mix of light hydrocarbons (methane, ethane and propane) and carbon dioxide. Generally very large concentrations of methane and CO2. In this case, these two gases (methane and CO2) have a clear association with the larger petrogenic ethane and propane gases. In addition these coherent anomalies occur at sites where the ethane/propane ratio exhibits somewhat noisy ratios with some sites having ratios less than one, a condition that is generally found only within macro gas and oil seepage environments where both volatilization and degradation can randomly alter their ratios. The logical conclusion is these biogenic gas anomalies associated with noisy ethane/propane ratios are evidence of a macro seepage environment. In spite of the very regional spacing (1 km) the largest magnitude anomalies clearly suggest two main clusters of anomalies. One occurs on and along strike with the Aiduna fault zone, and the second clusters along the coast line near the mouth of the Aiduna and Umari rivers. These anomalies suggest deep source oil potential exists over the entire area surveyed. The Aiduna River traverse crosses the northern trace of the inferred Aiduna fault with more impressive anomalies, including the largest magnitude propane and C2+ gases found, following fairly close to the Aiduna fault trace. These oily soil gas anomalies confirm the existence of a wide-spread and active subsurface petroleum system. Given adequate density, it appears that future soil gas surveys could provide a cost effective approach to focusing on and defining areas which could be further developed before much more expensive exploration tools (seismic) and drilling are employed. An offshore sampling survey might confirm and extend these coastal anomalies into the adjacent offshore.

Abstract
Carbon Dots (CDs) are materials that play a role in non-toxicity, biocompatibility, high photostability, changeable photoluminence, high solubility, and easy functionalization. Cellullose Nanofiber (CNF) is an environmentally friendly polymer that has biodegrability, good dispersion capabilities, and able to optimize material characteristics. In this research, CNF was added to the CDS synthesis process to determine the effect of CNF on CDs optical properties. CDs were characterized using Fourier-transform Infrared Spectroscopy (FTIR) to determine the chemical bond content on CDs. Absorbance properties with a UV-Vis spectrometer. Photoluminence properties using a photoluminescent (PL) spectrometer. The results of FTIR characterization obtained indicate that the CNF obtained can maintain the chemical bonds formed on the CD. From the UV-Vis results, the CNF approval gives an increase in the intensity of NIR absorbance from the CDs. While based on the result of PL characterization, there is a decrease in emission intensity from the resulting CDs.

Abstract
Structuring land ownership in Indonesia began in 1960 with the issuance of the Agrarian Basic Law. However, land issues are even more complicated as the global economy develops. Demands for the ease of obtaining land rights, especially from business entities, are increasingly high, including those from non-legal entities such as CV. This demand was also answered by the Government by issuing a Circular of the Minister of Agrarian and Spatial Planning / National Land Agency (ATR / BPN) Number 2 / SE-HT.02.01 / VI / 2019 concerning Granting of Right to Build Building for the Commanditaire Vennootschap. This paper tries to discuss two important things related to ownership of land rights by business entities that are not incorporated, specifically CV. First, what is the regulation of land tenure with the status of building rights in Indonesia? Second, how is CVs position as the subject holder of the use of buildings in Indonesia? Through normative juridical studies, conclusions are obtained as follows: First, land tenure arrangements with the status of building use rights in Indonesia have been carried out both through the Agrarian Basic Law and the regulations below, especially Government Regulation No. 40 of 1996 concerning Right to Cultivate, Right to Use, and Right to Use on the land. Second, there is a juridical problem regarding the position of CV as a non-building subject holder in Indonesia, since CV is not a Legal Entity that can own land rights.

Abstract
The efficiency of a thermoelectric material to be used as a heat machine is characterized by its thermoelectric figure of merit ((ZT)). The figure of merit itself is dependent on three transport quantities: (1) electrical conductivity ((sigma)), (2) Seebeck coefficient or thermoelectric power ((S)), and (3) electrical thermal conductivity ((kappa_e)). The three quantities are calculated through Boltzmann transport theory using constant and inverse-density of state relaxation time approximation. In this paper, we investigate the thermoelectric properties of various width of ribbon system containing topological edge states. These systems are discussed here due to its unique nature for having both insulating states inside the ribbon and conducting states at the edge which is topologically protected. The width of the ribbon depends on the number of one-dimensional wire stacking. We seek to determine the enhancement effect of manipulating this quantity on thermoelectric properties of the ribbon system and compare it to the conventional bulk system on two-dimensional semiconductors.

Abstract
Seismic method has been used as a non-destructive alternative in geotechnical testing. Through this test, several geotechnical parameters can be determined, while mantaining low costs, time and environmental impact. However, seismic wave sensors that are commonly used (geophone), are usually expensive and heavy. Since 2004, there have been several research that develop and prove the capabilities of MEMS accelerometers as cheaper and lighter seismic wave sensors. This study aims to develop a seismic wave sensor based on the MEMS ADXL335 accelerometer, calibrate its frequency response, and determine the field performance of the seismic wave sensor. The frequency response calibration is done in the range of 10-100 Hz, and will be presented as a plot of sensitivity to frequency. A subwoofer was used to simulate sinusoidal movement on a tested accelerometer with a controlled frequency, and on a 10 Hz traditional geophone as a reference. Geophone’s maximum signal gives maximum velocity of the sinusoidal movement, thus by utilizing simple harmonic oscillation equation, maximum acceleration of sinusoidal movement (and later MEMS accelerometer’s sensitivity) could be acquired. High resolution oscilloscope was used on to record MEMS accelerometer and reference geophone output signal during frequency response test. Field test was done using three identical accelerometers with ±40 cm spacing, using sledgehammer to generate seismic wave and 16-bit seismograph to record detected ground vibration. Frequency response calibration shows relatively constant responses 10 – 100 range (±3 dB tolerance towards static sensitivity), proving MEMS accelerometer’s wide bandwidth and superiority in measuring low frequency vibrations. Field test shows accelerometer’s ability to smoothly integrate with a seismograph and detect surface wave in field setting.

Abstract
Hydraulic fracturing has become an important method to increase the productivity of the well. Hydraulic fracturing will occur if the rock in the formation is given a tensile stress magnitude higher than the rock’s tensile strength. The insitu stress around the wellbore is unlikely to be tensile but some stress condition around the wellbore could lead to hydraulic fracturing given a pressurized fluid in the wellbore. We consider a two and three dimensional wellbore and assumed to be linear elastic and isotropic. Calculation and vizualiation of stress distribution around a wellbore has been done using finite element method. The model is applied by a minimum horizontal, maximum horizontal, overburden stress and the wellbore pressure. The wellbore pressure and the wellbore direction condition is variated. Some of the wellbore pressure data is derived from fracturing theory like Terzaghi, Daneshy, and least principal stress criterion. The data about the tensile strength of the rock around a wellbore is needed to predict wether the fracture will occur or not. The result show that there will be some minimum wellbore pressure and stress region that could lead into tensile failure that could lead to hydraulic fracturing. We also observed that the stress distribution in the horizontal well could predict wether the fracture will be transversal or longitudinal.

Abstract
Sunspots are darker, cooler areas on the surface of the sun and have strong magnetic field. The morphology of the sunspots group is classified into seven types based on the Zurich classification. The Zurich classification was modified and expanded to improve the objectivity of the definition of sunspot classification. The modified classification is called McIntosh classification that has other parameters to classified sunspot such as size, stability, and complexity. Sunspot has proper motion - the result of the interaction between solar rotation, magnetic field, and convection. In this study, we measured the coordinates of 304 sunspots umbra as tracer in the rising phase of the solar cycle 24th to obtain the relation of sunspots umbras velocity to Zurich and McIntosh classification. Coordinates of sunspots were measured using AIA images at a wavelength of 4500 Å from SDO (Solar Dynamic Observatory) with JHelioviewer software. From the measurement, we got that for the penumbral class in McIntosh classification, x class (no penumbra) and r class (incomplete penumbra) has the largest latitudinal and longitudinal velocity. For the sunspot distribution in McIntosh classification, i class (intermediate) and c class (compact) has highest latitudinal and longitudinal velocity.

Abstract
Multichannel seismic reflection data processing of line 250 at the Coast of Southern California has been done by using Echos®. The purpose of this research is to separate multiple reflections from the primary reflection. Multiple reflections yield dramatic effect especially on marine seismic survey. Multiple reflections in marine seismic data is the noise caused by waves that trapped in a layer of sea water or rock layers. One of geophysics exploration problem is removing multiple reflections from primary reflection. Multiple reflections often destructively interfere with the primary reflection making interpretation difficult, so it’s needed to get seismic section free from multiple reflections. There are some methods to attenuate the multiple reflections, one of them is Hyperbolic Radon transform. Hyperbolic Radon transform method works by transforming the data from time-offset domain into the Radon domain. Primary reflection and multiple reflections can be separated into Radon domain. In the end of this research, seismic section before and after multiple attenuation using hyperbolic Radon transform were compared. Based on the result of processing, it can be concluded that hyperbolic Radon transform is effective to attenuate multiple reflections at 0,24-1,25s TWT. But, it can eliminate some of data and makes seismic section seen unclear.

Abstract
Today, nuclear technology has become one of the most interesting research objects in the world. With many nuclear reactors operating in the world, both power reactors and research reactors, and the application of nuclear technology in all fields can have a detrimental effect in the form of releasing radioactive material into the environment. Other than that, there are also natural sources of radiation that have emerged naturally due to natural symptoms that occur on earth and radiation that is in the human body (internal radiation). Natural radiation is the biggest contributor to the radiation source that humans received in one year. So it is important to monitor radiation in an area, especially radiation from natural sources. Natural radiation monitoring is carried out by mapping natural radiation of certain areas, so that spots of the area are found which have anomalies in environmental radioactivity. In addition, it is necessary to study radionuclide transfer factors for environmental elements such as soil, plants, etc. This study used an experimental method by measuring radionuclides in several samples. Sampling is done in an area in Lembang. The samples taken were soil and grass, then measured using an ORTEC gamma spectrometer with HPGe detector. Based on the measurement of samples, it can be concluded that in the area there is no anomaly of radioactivity in the environment and still at a safe level of radiation.

Abstract
Pore pressure prediction methods have been developed by several researchers who only use well log data as a basis for determining the relation between velocity and pore pressure. Pore pressure prediction by using laboratory measurements to get the relation with velocity is still rarely conducted. In this paper, the prediction of pore pressure is done in multi-stages or sequentially involving the results of rock physics laboratory measurements for each reservoir lithology (carbonate, basement, and sand) and combining them with field measurement data for each well using statistical rock physics and statistical neural network methods. This method involves all measurement data from the core in the laboratory, well data, including data: lithology, measurement of pressure data in well (RFT, DST, etc.), hydrostatic trend, acoustic and elastic log data, porosity, and mud weight information. The whole data are trained using statistical neural network. Then, the knowledges are used to predict the pore pressure by considering lithofasies of log and also seismic lithology.

Abstract
The vibration produced by an earthquake can cause liquefaction. Liquefaction events in the wells are influenced by the nature of soil, geological environmental and earthquake characteristics, as well as other factors such as rock grain size, groundwater level and ground vibration acceleration. There were a number of cases after the Lombok earthquake which were indicative of the occurrence of liquefaction, especially those observed at the location of residents water wells. After earthquakes, we found many phenomena of dry water wells, the occurrence of siltation of wells, broken pipes in deep drill wells, and the collapse of the walls of wells. Generally the surface soil layer in Lombok is loose sand, and as is known that the loose sand layer has a higher potential for the occurrence of liquefaction due to its grain characteristics. This paper presents sand grain size analysis of wells in North and West of Lombok which undergo liquefaction when 2018 Lombok Earthquake. The result show the distribution from shieve analysis, microscope sampling results, and also distribution from laser particle size analysis. This study is essential for the further analysis to the resistance of wells to vibration of erthquakes.

Abstract
Cap-rock integrity as well as reservoir integrity assessments have become a key element in the design and operation of steam injection projects and a critical element in the selection of a maximum steam injection operating pressure. The applicability of steam injection requires good knowledge of reservoir and geomechanic aspects. In addition, injecting steam into a very shallow unconsolidated reservoir has potential risk of having loss of containment issue. By necessity, these cap-rock integrity assessments involve geomechanical engineering principles and have generally lead to more use of reservoir-geomechanical simulations (one way coupled or sequentially coupled) in the establishment of what is termed “safe” maximum steam injection pressures. In this method, geomechanical parameter (stress state model (overburden, hydrostatic and pore pressure), elastic model (Young Modulus, Shear Modulus, Poisson including failure criteria i.e. Mohr-Coulomb), and rock’s reservoir properties (lithology, porosity, permeability, water saturation etc.) are required as input data. The methods will integrate the whole data with coupled reservoir properties and geomechanics modeling to calculate changes of rock strength due to steam injection. These cap-rock assessments have included geological framework studies of caprock, insitu stress determination, reservoir and cap-rock property characterization, failure criteria from numerous situations and numerical simulations to ensure the steam injection scenario always in proper condition. Alternative injection scenarios are suggested to be performed in risk area, as follows: (a) Steam injection and production are performed simultaneously; (b) steam injection, heating and production are performed simultaneously; (c) heating, production and injection are performed sequentially.

Abstract
ABSTRACT Introduction: The incidence of cardiac arrest outside the hospital is still a frequent and even increasing frequency. While CPR volunteer assistance has been widely reported at low rates in various parts of the world (Abella, 2008). This requires the existence of other recommended methods and methods so that the level of availability and knowledge of CPR volunteers becomes greater. Teaching to early age is recommended because the earlier they know the management of CPR, the better their knowledge will be in the future. Children are learners who are quick and easy to motivate. This then encourages researchers to examine alternative methods that can be used to increase the knowledge and number of CPR Volunteers. Objective: The purpose of this study was to find out the benefits of using Puzzle games in increasing knowledge about CPR in elementary student of SD Kedungpedaringan Kepanjen. Method: Research method was Quasy experimental. The sample used was 44 people by simple random sampling. Samples were divided into 2 experimental groups, group 1 used standard teaching techniques (SAP), Group 2 used Puzzle games. Results: There was a significant effect (p <0.01) between learning using SAP / Module and Puzzle Games on the level of knowledge of respondents before and after treatment. Responded stated that he preferred learning using the Puzle game. Discussion: Puzle game is a form of educational game which functions not only as a means of play but also a form of education to students. The function of the game is to create a pleasant atmosphere for students. With a pleasant atmosphere, students can receive and understand information that is conveyed more easily.

Abstract
The regional head elections for governors and deputy governors of Bali in 2018 have succeeded in bringing I Wayan Koster and Cokorda Artha Ardhana Sukawati (Cok Ace) as governors and deputy governors of Bali for the period 2018 - 2022. Behind the victories and democratic events the election money politics to get voice support from certain candidate pairs. The political practice is wrapped in customary legality named danapunia. This paper aims to describe how politics and world practices are carried out and legalized using Pierre Bourdieus Habitus Theory perspective (M × H) + T = Practice. Description: M is capital, H is habitus and T is the domain or place. The method used descriptive qualitative by collecting data through in-depth interviews with selected informants. Informants were taken from representatives of the adat village and the auxiliary state of Bawaslu as institutions authorized to oversee election administration. This study produces several analyzes, namely: first, the practice of doxa explains and the world has sacred values, both in the teachings of Hinduism. This value shapes the mental cognition of agents and social structures in legalizing and danapunia in the political arena. Second, the practice of heterodoksa in habitus is presented by Bawaslu as an auxiliary state institution that does not have the power of formal law and the authority to carry out the oversight function of elections. Third, the practice of orthodoxa presented by the intervention of the PDIP political elite in perpetuating and promoting the world. Practices and worlds are supported by economic, cultural and symbolic capital resources carried out by political actors and Bali as the realm of the partial power of PDIP which is also a shaper of political and world practices.

Abstract
There are many ways to improve the performance and productivity of broiler chickens In animal husbandry. One method that is often used is by giving antibiotics into feed or livestock rations. Antibiotics given to chickens aim to reduce harmful microorganisms in the digestive tract of chickens. The use of antibiotics in the long run if consumed continuously will cause residues in the consumers body and this is very dangerous for those who consume them. Antibiotics are used to improve meat and egg production. a combination of probiotics and prebiotics aims at nutritional therapy and maintaining digestive health, to increase the digestibility of foods that contain a lot of crude fiber, eliminate the smell of ammonia in feces, increase the immune system, help increase growth and productivity, compete against pathogenic bacteria that harm and improve quality feed by increasing protein levels. The purpose of this study was to analyze the maintenance of broiler chickens using synbiotics. The study used broiler DOC with a total of 200 animals obtained from the Bandar Lampung which was maintained in two maintenance cages, each containing 100 chickens. The first partition without using Sinbiotik (control) and the second bulkhead using synbiotics mixed into drinking water. The results of the study showed that giving sinbotik had an impact especially on broiler performance with consumption of 1.522 g / head ration, Weight gain 1,152.1 g / head, FCR 1.32 and 0% mortality, and ration efficiency of 75%

Abstract
Tokay gecko (Gekko gecko, Linnaeus 1758) is a small country lizard animal that has a diverse skin color that is decorated with red spots to orange on its back. The study of variations in morphology is very important in various aspects, especially in describing the definition of a species. This study aims to determine the morphological variations based on morphometry and meristic of Gekko gecko in each population. In this study PCA and UPGMA analysis were carried out. The design in the study begins with the measurement phase of 24 morphological characters. The results displayed will be eigenvalue tables, scatter plot graphs and dendograms. The results obtained were then analyzed descriptively. A total of 122 samples of Gekko gecko (male = 81; female = 41) originating from various populations showed a number of character variations between individuals and populations. On certain islands have dominant characters in each population even though these characters are also found in other populations with relatively small values. Gekko gecko in the six populations illustrates overlapping groupings and no significant or dominant character has been seen so that no special character can be found that can be used as a diagnostic character in the Gekko gecko population in a particular population.

Abstract
Bacterial Leaf Blight (BLB) disease is a one-factor cause of decreasing rice production in Indonesia. This disease caused by Xanthomonas oryzae pv oryzae (Xoo) which infected rice leaves to yellowish. Xoo isolates were obtained from three different locations namely West Java, West Sumatera, and West Borneo. Each isolate was identified by using primer specifics in colony Polymerase Chain Reaction (PCR) techniques. Isogenic strains that contain resistance genes were infected and observed through pathogenicity tests. Based on results, Code variety holding Xa4-Xa7 gene had a high resistance level on Xoo infection from all locations compared to other isogenic and popular rice strains. In the meantime, IRBB5 holding Xa5 gene survived the attack of Xoo from West Java and West Borneo properly. The infection intensities on Code and IRBB5 consecutively are 1.62% and 3.55% for West Java isolates, 2.10% and 2.97% for West Sumatera Isolates, 2.17% and 4.45% for West Borneo isolates

Abstract
Study of endophyte bacteria from Purwoceng roots (Pimpinella pruatjan Molk.) lead to characterized endophyte bacteria that can produce the same secondary metabolite compound as its host. Secondary metabolite from this bacteria can be used as antibacterial against Pseudomonas aeruginosa. This research aims to determine antibacterial activity of secondary metabolites purwoceng root endophyte bacteria against P. aeruginosa growth, characterize the group of secondary metabolites produce by endophyte bacteria and identify potential endophyte bacteria using molecular character 16S rRNA gene sequence. Method used in this research such as antibacterial activity assay to determine potency of antibacterial compound produce by endophyte bacteria against P. aeruginosa growth, thin layer chromatography (TLC) assay to characterize the group of antibacterial compound and sequencing of 16S rRNA gene to determine the strain of potential endophyte bacteria. The result of bacterial activity showed GP2, GP14 and DG1 isolate produce antibacterial compounds by forming inhibitory zone in antibacterial activity assay. Antibacterial compounds produce by GP2, GP14 and DG1 isolate belong to alkaloid family which has the ability as antibacterial. Based on molecular identification GP14 and DG1 isolate has the similarity with Bacillus subtilis by 99%, while GP2 isolate has the similarity with Enterococcus faecalis by 99%.

Abstract
This study aims to describe empirically the profile of the academic success of students in high school. This research is motivated by the assumption that academic success of students is only influenced by cognitive abilities possessed so that it can be said that achievement is a realization of cognitive abilities but it turns out that a persons cognitive aspects do not always guarantee individual academic success. The qualitative approach involved respondent of 786 in Bandung, West Java, Indonesia. The data analysis used descriptive statistics with SPSS ver 14.0. The study shows the general academic success of students in Bandung in the category of moderate. Furthermore, the results of the analysis of academic success based on sex indicate that there are no significant differences. Research recommendations, namely for counseling teachers can design guidance and counseling programs that are able to direct the achievement of academic success using classical guidance services or group guidance.

Abstract
Indonesia is an archipelago that consisting of a group of islands from Sabang to Marauke. To be able to communicate each other, it needs a telecommunications network that can load all regions of Indonesia, without exception. The use of satellites as a means of telecommunications is very suitable to be applied in Indonesia. Because by using satellites, operators can provide internet services to rural areas that cannot access intrenet services by terrestrial networks. This is what causes businesses in this field is very promising. However, this business is not an expensive business because it requires very large costs in planning until operating. Therefore, it takes a research that shows the feasibility of this business for people to investment. In this paper shows that, NPV value during the active period of the satellite was USD 555,804,583 with an IRR value of 7% with PBP 5 years 8 months. Based on these parameters it can be seen that the investment is still classified as feasible to continue.
