Abstract
The right procedures of wudhu (ablution) and tayammum can be learned in various ways, such as books, articles, video tutorials, and from the internet. For children, usually, learn about wudhu and tayammum procedures using books. But sometimes it will be difficulties for them. Video tutorials are easier to understand than books, but now there is one technology that uses 3 dimensions that will look more attractive to children. Name is Augmented Reality (AR). In this method, we used the marker. The program will read the object from the image marker then a moving object or output that is already present in the data will be displayed. This application was made for the Android OS, and software used to create this application is 3D Blender and Unity 3D. In this research, we develop android-based learning media using AR technology for wudhu and tayammum procedures. With this application, children can be more understood by seeing hearing and feeling what they are learning, and children become more enthusiastic in learning. The calculation of the questionnaire about this application, shown that the AR learning media application is very easy to use, practical, useful, and effective in supporting learning activities. Besides this application is also appropriate to be used as an interactive learning media for children. An attractive interface design makes children as users feel happy and interested when using it.

Abstract
Corruption is a form of fraud that can harm other parties. In Indonesia corruption means that it is a criminal offense related to state finance in the government sector and involves public officials. So to reduce the potential for corruption, prevention efforts are needed. The purpose of this study is to analyze how risk management prevents corruption. This research uses a qualitative case study method. The object of research was carried out at the Banyuwangi Regency Government. The reason for choosing this object is because the Banyuwangi Regency Government has implemented a risk-based audit. This study focuses on selecting three work units, namely the Inspectorate, the Financial Management Agency and the Asset Management, and the Public Works Agency. The results showed that the identification of corruption risks can be classified based on the red flag, namely (1) the accuracy of the goods and services received at the time of procurement, (2) identification of indications of corruption. The implication of this research is to know the risk of corruption, we can minimize corruption by controlling both operational and strategy control.

Abstract
The most state revenue is from the tax sector. The government has tried its best to increase revenue from the tax sector from year to year. However, the development of tax variations by the government must not ignore the principle of justice. Likewise in the imposition of e-commerce tax, the government is based on the principle of equity. The imposition of e-commerce tax is regulated in Minister of Finance Regulation Number 210 Year 2018 concerning g Tax Treatment of Trade Transactions Through Electronic Systems. But this regulation was later withdrawn by the Minister of Finance. The reason behind the withdrawal is that the rules are often misinterpreted by the public and business actors because they think the government imposes new taxes on e-commerce players. The government considers that e-commerce tax is important so that there is equality of tax treatment among business people. But on the other hand e-commerce actors want treatment between them and the same online. E-commerce entrepreneurs believe that even though it is not yet regulated in a Ministerial Regulation, e-commerce actors in Indonesia actually pay taxes according to the terms and conditions. The existence of these two different perceptions, the government policy to develop e-commerce tax needs to be reviewed again whether it is necessary to have a special Ministerial Regulation governing e-commerce tax or not. To achieve these objectives this research uses an exploratory approach. With a qualitative explorative method this research produces explorative analytic data. Activities in analyzing this include reducing the data obtained by looking at the concepts and development of the application of the principle of equity in the imposition of e-commerce tax and then presenting data that can provide definitions or explanations about the concepts or patterns studied in the study.

Abstract
Volcanic data is in the form of broadband data that has a wide range of frequencies and contains a high level of noise. So that the noise decomposition process must be chosen correctly, it is intended that the volcanic seismic recording data containing event information contained there in is not decomposed. For this reason, noise decomposition has been carried out by applying the wavelet process, namely by using wavelet decomposition on the recording data at the Wanagama station during the Merapi volcano eruption in 2010. This decomposition of noise uses Daubechies db 5 level 5 detail 1 wavelet decomposition. Level 5 detail 1 is able to decompose noise well and volcanic earthquake events are obtained during the eruption. One of them is the event of deep volcanic earthquake (VT-A), shallow volcanic earthquake (VT-B) and pyroclastic flows that occurred during the Merapi eruption on October 26, 2010 and November 3, 2010.

Abstract
Banks as creditor and capital lenders are now required to integrate the aspects of the social environment and governance into their main business, so nowadays banks not only manage the reputation and risk but also seek to realize a sustainable business transformation. Banks contribution as institutions can reduce the unemployment rate, which is increasingly rising in every year. Based on this situation the Bank as a source of funding in the economic sector can provide priority scale when it will give a credit to the Micro Small Medium Enterprise (MSME) sector. The MSME sector in several other countries is considered to be able to overcome unemployment, supporting the community to be able to prioritize entrepreneurship in order to create a sustainable business and even better if from the development of MSME businesses also can create job field. Thus the Bank is one of the economic pillars in Indonesia that can contribute to creating inclusive and sustainable economic growth. Based on these conditions, it is necessary to have financial sector policies that need to be reform or create in order to support the realization of an inclusive and sustainable Indonesian economy and to reduce unemployment in every year. Therefore, it is necessary to study further through mapping the regulations regarding banking sector policies in terms of realizing an inclusive and sustainable economy by optimizing the role of MSME. The ultimate goal is that all levels of society have the same opportunity to use banking financial services.

Abstract
In the era of globalization with the advancement of transportation and technology as it is now working abroad is something we cannot avoid. Regardless of the level of education and background of competence. Seeing friends, neighbors around success by working abroad then become an attraction for everyone to imitate. Apart from the various problems encountered when working abroad, it is often overlooked and ignored. The purpose of this paper is to convey ideas that can be used to improve the gaps in the implementation of the protection of Indonesian migrant workers. The method used is researchers call the collaborative governance approach and local wisdom as a way to solve the fundamental problems of prospective Indonesian migrant workers if they want to successfully work abroad. The results of this study indicate that this approach will be very effective in solving their basic problems starting from the lowest level, namely the village. Every village community is used to having the wisdom that has been carried down for generations as their culture. The village government as the lowest institution that is directly in contact with the problems of the community has an interest in the security and safety of the citizens of their community who will work abroad.

Abstract
A minor breakdown of the cooling system will cause engine overheating. One of the factors causing the engine overheating is the crust on radiator of cooling system. Based on the problem, therefore, corrosion on the cooling system, especially radiator, should be controlled. There are some methods in controlling the corrosion; one of them is the inhibitor treatment. The research aims to know the corrosion mechanism, the corrosion type, and the kind of inhibitor that produces the lowest corrosion rate. The tool used to measure the chemical composition of the radiator is spectrometer, while microscope optic is used to know the radiator corrosion type. The corrosion rate testing is used three electrode cells according to tafel extrapolation method. The results of the test of the nitric acid inhibitor treatment with the addition of various methods showed that the most optimal result is on the addition of nitric acid inhibitor by 5%. It is proven by the decrease of corrosion rate from 0,002207 mmpy to 0,00171 mmpy.

Abstract
Without adequate capital to be a reserved fund for the failure of a business, a risk-taking entrepreneur might fall into bankruptcy and suffer trauma to restart the business. Unfortunately, literature sees that risk-taking behavior is a positive characteristic of an entrepreneur and makes it a linear variable in which the higher the risk is taken, the better the entrepreneur-s orientation is. This research aims to explore the entrepreneurs- excessive risk-taking behavior from the goal-setting perspective to have a better understanding of entrepreneurs- reaction to the environment. To achieve the goal, we collected data from 383 leaders of Village-Owned Enterprise (BUMDES) in Central Java. The quantitative analysis suggests that risk-taking behavior varies based on environmental uncertainty, organization commitment, and entrepreneurs- creativity. This shows that when related to excessive risk-taking behavior, consideration should be given to the environmental factor (which is environmental uncertainty) and individual factor (which consists of commitment and creativity).

Abstract
Sinjai is known as Bumi Panrita Kitta (Land of Islamic scholars). This popularity has become a discourse for some people. Some claim that it is true, but others are somewhat doubtful. Therefore, this research is interesting to do. This research focuses on the track record of Panrita-Anreguru (scholars/ulama) in Sinjai on a historical-synchronic basis. For this purpose, a historical methodology is adopted, namely: Heiristics, Source Criticism, Source Analysis, and Interpretation. It was found that early in the XVII century Islam was accepted by the Sinjai people. Since then, Islamization has been dynamic and massive. That was due to the collaboration of local scholar and Ruler. Eventually, a figure called Panrita (Expert) or Anreguru (Great Ulama) was born. The mastery of religious knowledge and Panritas skill in transmitting the knowledge, gave birth to a new term namely Anreguru (Great Ulama). Efforts in transforming sc Someone who has the qualification of Panrita-Anreguru hows the depth and breadth understanging of the Islamic sciences they master. The Panrita-Anreguru figures include: Dato ri Bandang, Dato ri Tiro, Laming, Puang Belle, Puatta Massabangnge, To Maeppe daeng Situncu, Syek Ibrahim Rahmat, I Bolong daeng Makketti, and others.

Abstract
This study aims to analyze peoples perceptions of development after the emergence of village funding policies and how they affect the level of community participation. The method used in this study is socio-legal research. The research location was determined purposively in several villages in Borobudur District with the consideration that the villages also received other assistance in the framework of establishing Borobudur as a super-priority for tourism development. Data obtained through deep interviews will then be analyzed and presented qualitatively. The results showed that there had been a change in peoples perception of village development. Development, which is supposed to be the full responsibility of village communities, is now the responsibility of the government. Villagers who have been the main actors have shifted to implementing programs and activities. For example, village development planning must follow the policies of the local government. Village communities who are supposed to work together to carry out development have turned into workers who get paid. The next implication is the low level of community participation in terms of both quantity and quality. The policy of channeling village funds sourced from the State Budget (APBN) and the Regional Budget (APBD) has succeeded in accelerating village development, however, on the other hand, it has also degraded the local values ​​of the village community. Policy formulation Participatory village fund distribution based on local community values ​​becomes very urgent to be formulated and implemented.

Abstract
Catalytic Isomerization of n-hexane over Beta (BEA) zeolite synthesized by dry gel conversion (DGC) and hydrothermal (HTS) methods were studied. The isomerization was influenced by types of synthesized methods, and combined selectivity for branched alkanes (2- and 3-methylpentanes, 2,2-dimethylbutane, 2-, and 3-methylbutanes, 2,2-dimethylpropane, and 2-methylpropane) decreased in the order: BEA (DGC) > BEA (HTS). BEA synthesized by DGC had the highest activity and selectivity for the isomerization, and BEA Synthesized by HTS has the highest activity for cracking to lower alkanes and alkenes. These differences are ascribed to the difference of surface area, pore volume, acid properties, and reaction parameters.

Abstract
Godly children are not born but are formed by the process of education from an early age. One of the main subjects in childrens character education is fiqh. Fiqh is needed to understand children about Islamic law. Because the object of fiqh is adults, fiqh tends to be taught to school-aged children, especially middle and upper, both informal and non-formal schools (Islamic boarding schools). Though it would be better if the concepts of fiqh were taught and practiced early on. Also, the concepts offered in fiqh can be used as a basis in the process of shaping the character of children. Although the age of the child is not yet entering adulthood (mumayiz) and does not yet have an obligation to implement the laws in Islam, the child must have prepared an understanding up to his amaliyah. In this research, several character values that can be developed through fiqh of childrens education have been found, namely religious, honest, tolerance, discipline, creative, independent, curiosity, communicative, environmental care, social care, and responsibility. The application of fiqh laws in daily life must be practiced as best as possible to increase the value of childrens religiosity so that human character is formed.

Abstract
Magnesium and its alloy are known as biodegradable materials. Application of these materials especially as an implant materials such as fracture fixation, cardiovascular stent and musculoskeletal. Characteristic modifications of these materials have been extensively done by some treatments. The objective of this paper is to review some treatments of the magnesium and its alloy to increase their characteristic as a biomaterial. In this paper, the treatment of magnesium and its alloy by coating, surface mechanical attrition treatment (SMAT), shot peening and thermal oxidation was reviewed. Some properties were studied base on these treatments such as corrosion resistant, morphology, wettability, and biocompatibility. Coating treatment by calcium phosphate was developed for orthopedic application. SMAT resulted in grain size of nanometer in the topmost surface of magnesium. Surface roughness and wettability also increased on the SMATed specimen but its corrosion resistant decreased. Severe shot peening on magnesium for orthopedic application should be studied intensively. Thermal oxidation of magnesium alloy improved both wear and corrosion resistant.

Abstract
Central Java and East Java are provinces in Indonesia which have the largest area of teak forest where management is in PERHUTANI. Teak trees can be cut down after reaching the age of 10 years or meet the minimum stem diameter required. Utilization of teak wood for the needs of building materials and furniture is very high because the material is of good quality. In processing teak tree trunks, there is waste from cutting that has not been maximized by PERHUTANI. With good quality teak wood, try to learn about the utilization of PERHUTANI teak wood waste powder for use as a bio-pellet that is included in the Renewable Energy category so that they can improve their use and economic functions. value. The bio-pellet quality reference standard refers to the SNI standard. To make bio-pellets, flat die mill type machines are used with speeds of 1660 rpm. As an adhesive used cassava flour with a variation of 5%; 10%; 15% and water variations 10%; 15%; 20% by weight teak wood dust. Compaction pressure variations are obtained by adjusting the gap between the roller and die with the distance 0.5mm, 1mm and 1.5mm. In research conducted content contained in teak wood pellets can meet SNI product standards. The five SNI standards obtained were bio-pellets having calorific values greater than 4000 calories/gram, bound carbon values ≥ 14%. Volatile content is less than ≤ 80%, ash content ≤ 1.5% and has a density of ≥ 0.8. This shows that bio-pellets from teak wood waste can be used for rural communities and can be developed for industrial purposes.

Abstract
Postdate pregnancy is an indirect cause of maternal and infant mortality. Generally, it can occur around 7% of pregnancies. The number of deliveries in postdate pregnancy in Regional Public Hospital of Wonosari is 34%. The objective of the study is to describe the characteristics of intrapartum women with postdate pregnancy, delivery method, and fetal outcome at Regional Public Hospital of Wonosari in 2018. A quantitative descriptive research was use in this study. The sample was obtained by a total sampling technique as many as 601. The results of the study showed that the majority of intrapartum women with postdate pregnancy were at the age of 20-35 years (75.4%), multiparity (55.1%), and spontaneous delivery method (73.7%). Fetal outcome (86.5%), babies who were not asphyxia and weighed 2500-4000 grams as many as (92%). All of these characteristics often occurred in the gestational age range of 40+1 – 40+6 weeks (56.6%), range 41-41+6 weeks (40.6%), and > 42 weeks (2.8%). The success of induction was indicated by the high rate of spontaneous delivery (73.7%), no incidence of asphyxia at > 42 weeks gestation, and low macrosomia rates (2.7%) in post- term pregnancies in Regional Public Hospital of Wonosari in 2018. Good fetal outcome due to the right termination efforts can be one of the considerations in the preparation of Standard Operational Procedure (SOP) for the management of postdate pregnancies in Regional Public Hospital of Wonosari.

Background. Pulmonary tuberculosis is a health problem, both in terms of mortality, disease incidence, and its diagnosis and treatment.In 2015, there were 175,029 positive cases of smear pulmonary tuberculosis. Lung tuberculosis according to sex is more prevalent in males with a prevalence of 106,554 (60.9%) than females with a prevalence of 68,475 (39.1%) cases. Based on data from the Pekalongan District Health Office in 2016, Pekalongan had 610 positive BTA lung tuberculosis suspects consisting of 338 positive BTA positive men and women with 272 BTA positive from quarterly 1 to quarterly 3. Objectives. To explore the characteristics of pulmonary tuberculosis patients in Kedungwunisubdistrict, Pekalongan Regency. Method. This was a descriptive quantitative study. Results. The majority of respondents were 38 men (62.3%), had an early age category (46-55 years) of 17 people (27.9%), almost half of the respondents had elementary school education that was 27 people (44.3%), most respondents had low economic status of 55 people (90.2%), almost half of the respondents had 27 jobs (44.3%), and the majority of respondents did not have the same TB as many as 42 people (78.9%). The results of this study are expected to be used in improving the quality of care in tuberculosis patients

Abstract
A slope has a high tendency to slide due to many factors coming from combination of external loads and internal soil properties itself. In any construction design, two things should be taken into account are stability and settlement. In case of landslide, slope is not stable, mobilizing stress in slope is higher than allowable stress. In order to reach target slope stability, earthwork solutions and or ground improvement solutions can be conducted. This study with the objective to propose some alternative earthwork solutions that have sufficient stability, soil test is performed. In this experiment, soil is taken from landslide location in Jepara, Central Java. The soil test aims to investigate index and engineering properties used as an input. In order to model earthwork in slope and to obtain its safety factor, application program Plaxis is used.

Abstract
Obesity is one of the risks of various diseases and can reduce the beauty of the body, especially mothers. From the survey data conducted by many mothers always complained by the name of gaining weight because they did not exercise while the food patterns were also not regulated they tend to prefer fast food (jungfood). Therefore one type of exercise used to reduce body fat is to do aerobic exercise. The success of decreasing body fat can be seen with aerobic exercise training models through the Circuit training model and body language training. In addition, it can also be seen from the consistency of exercise, adequate diet and rest, so that instructors need innovation or variation by applying appropriate training models. The research method used in this study is the experimental method. This research was divided into two treatment groups namely the experimental group and the control group. The two groups were tested for their initial conditions, before being given different treatments. In the experimental group the implementation uses the circuit training model, while the control group uses the body language training model in the implementation. At the end of the treatment the two groups were measured using tests and measurements using a skinfold caliper from Ismaryati (2006: 90). The data analysis technique in this study used a 2x3 factorial design variance analysis (ANAVA) technique at α = 0.05. With the normality test (lilliefors test) and the Homogeneity Variance test (with Bartlet test). The results of this study indicate that: 1. There are differences in the effect of the application of the circuit training model and the body language training model on decreasing body fat (Sig. 0.013 <0.05). 2. There is a difference in the effect of gymnastics mothers who have underweight, normalweight (ideal) weight, and overweight weight on the reduction in body fat (Sig. 0.000 <0.05). 3. There is no interaction of influence between exercise model and body weight on body fat reduction (Sig. 0.959> 0.05).

Abstract
The center dairy cattle in the Ngablak District including the location criteria which have leading sectors that can drive the growth of local and national economies. Potential dairy cattle with a population of 210 heads, 60 tails lactation milk production of 1,000 litre / day and as many as 255 head of beef cattle. Existing cattle organizations such as the Association of dairy cattle named Tri Argo Mulyo and has had a cooling unit capacity of 1,000 litre. This study aims to identify the characteristics of the farmers, the selling price of milk at farm level to the market and sellers dealings mechanism result dairy cows. The basic method of research is a descriptive and case studies. The sampling technique was conducted by multistage purposive sampling, while the data source of research focused on farmers, farm groups, the combined group of farmers, cooperatives, milk collectors and goverment agriculture department. The results of the study dairy cattle sector is an important sector of the local economy, regional and national levels, either directly or indirectly. Direct role sectors of dairy cattle contribute revenue from the supply of raw milk to cooperatives, wholesalers, industries, to the consumer, whereas indirect role has multiplier effects in the form of linkages availability of milk from the input to the output among industries that have collaborated with the cooperatives and associations, consumption, and investment is environmentally sustainable agriculture in supply of manure. Conclusion of the study, breeders as dairy cattle in Ngablak District dominate the supply of local milk independently, the certainty of prices that tend to be stable around 5,600 rupiah until 6,000 rupiah / litre, and the existence of a tiered marketing chain mechanism by the Association and Cooperatives.

Abstract
Cognitive performance had an important role played on students- academic success. Research on cognitive capacity profiles for children who lived in rural area was considered emergency. This is necessary to design appropriate teaching strategy for rural children. The purpose of the research was to describe working memory capacity and short term memory for Bajo-s children in primary school. The research used survey method which is consist of thirty five students from 4th grade in elementary school. Working memory was measured by using backward digit span and short term memory was measured by using fordward digit span. The result showed that there was not significance difference between working memory and short term memory. But, scores of short term memory was higher than working memory. These result indicate that low capacity of information manipulation in mind. Further research is need to create teaching strategy to improve working memory capacity.
