Abstract
Government regulations are made to provide equal distribution of peoples welfare. The law on National Health Insurance and health regulations give the people the right to get good health services. The existence of Perdirjampelkes Number 4 of 2018 concerning the Implementation of Competency-Based Tiered Systems through Information System Integration (Online Referral) has an impact on type C hospitals and their services. The BPJS online referral system was actually made to facilitate and improve the quality of services in hospitals, but it turned out to cause many problems in its implementation. This study focuses on exploring the fulfillment of the human service rights of patients in obtaining hospital services in the BPJS era. The purpose of this study is to explore the fulfillment of the human service rights of patients in obtaining hospital services in the BPJS era. This study uses qualitative research methods with a case study approach. Data was collected by interviewing 8 informants. The researcher found that RS Karya had taken proactive actions against sudden changes due to a tiered online referral system by increasing human resources and facilities to provide human service rights. BPJS applies tiered online referral rules that have an impact on not fulfilling human service rights. The new BPJS regulation can be a threat if the hospital does not change to improve quality and anticipate it with crisis management. Human services are carried out to provide patient rights without violating regulations made by BPJS. Suggestions for research are that hospitals need to form a crisis management team and prepare crisis management strategies to fulfill patient rights.

Abstract
Over the past few years the turnover rate of employees of the Husada Gresik Wates Hospital was 27% - 30%. In one month there are always employees who change jobs. On the other hand the ideal value for employee turnover is around 15% and if a workplace has a staff turnover level below or equal to the ideal number then the condition of a workplace can be declared healthy. This study aims to determine the effect of job satisfaction, organizational commitment and individual characteristics on the desire to move to work. This study was an observational analytic descriptive study with crossectional research design. The study was conducted at the Wates Husada Gresik Hospital. The population in this study were all employees at Husada Gresik Wates Hospital, namely 103 employees. The sample size is calculated by simple random sampling, which is 82 samples. The independent variables are job satisfaction and individual characteristics of employees. The dependent variable is organizational commitment held by employees of the Wates Husada Gresik hospital, where organizational commitment is seen as affective, normative and sustainable. The research data were analyzed univariately using the chi square test and bivariate analysis using linear regression test. The results of this study were that job satisfaction and organizational commitment had a significant effect on the desire to move to work. In general, respondents job satisfaction is high (72.2%) but for the salary satisfaction dimension it has a low level of satisfaction (37.3%). The organizational commitment of the respondents is classified as high (69.8%) with the commitment of sustainability having the highest level of commitment (79.8%). The desire to move work respondents have a thin difference, namely 53% have the desire to change jobs and 47% of respondents do not have the desire to change jobs. The conclusion in this study is that job satisfaction, organizational commitment and individual characters represented by marital status have a significant influence on the desire to move to work

Abstract Entering the retirement period is something that will experienced by each individual, especially those who pursue a career in the work. Readiness of a person when entering into retirement needs to be well prepared, especially economic or financially. This is because, when it enters retirement period, person income will be decreased. In the other side, the cost to life necessities will still be there, even higher because of the increase in the price in each year. When an individual will plan for retirement, the individual must have a good financial knowledge (financial literacy) to make the financial decisions is good. In addition to financial literacy, there are other factors affecting retirement planning this is risk tolerance, risk tolerance can influence the decision to be taken to plan retirement. This research is a quantitative research with the method of collecting data using questionnaires that shared to civil servants (PNS) in Ciamis city. Samples taken as many as 100 respondents. This research assisted with SPSS 21.0 statistical tools. Tests on this research used validity and reliability tests. Analysis method use classic assumption test, multiple linear regression analyses and hypothesis tests. The results showed that financial literacy has significant positive effect on retirement planning and risk tolerance factors have significant negative effect on retirement planning.

Abstract
The use of such agricultural by product as corn cobs is important in fulfilling the needs of feed for ruminant, especially during the dry season. However, the main problem of using corn cobs as a feedstuff is low digestibility due to the existence of the links between lignin and cellulose or hemicellulose. This study was designed to evaluate the effects of biodecomposer (BS) application on the changes of chemical components of corn cobs. BS was developed from the rumen bacterial of buffalo raised under typical feeding conditions. The effectiveness of BS application was assessed by fermenting corn cobs for 4 weeks. The experiment was run according to completely randomized design consisted of eight treatments and three replications giving total number of the experimental units of 24. The treatments were T0 = 100 g course ground of corn cobs without BS, T1 = 100 g course ground of corn cobs + 2.5% BS, T2 = 100 g course ground of corn cobs + 5.0 % BS, T3= 100 g course ground of corn cobs + 7.5% BS, T4= 100 g course ground of corn cobs + 10% BS, T5 =100 g course ground of corn cobs + 12.5% BS, T6= 100 g course ground of corn cobs + 15% BS, and T7= 100 g corn cobs + 0.6% Starbio (commercial biodecomposer). Increasing level of biodecomposer is expected to have a significant effects on the chemical composition in the corn cobs.

Abstract
Water is widely used as a heat carrier in various devices such as automotive and nuclear reactors. Because of its better thermal characteristics, currently nanofluid is a candidate for replacing water and other conventional cooling fluids such as ethylene glycol and oil as a heat carrier. In this study, Al2O3 nanoparticles have been synthesized by the hydrothermal method for heat transfer nanofluid as an alternative to the new cooling fluid. Nanoparticles were synthesized using AlCl3 as a precursor, and urea was used as a capping agent. The hydrothermal process was carried out at 175oC for 17 hours. The hydrothermal product was dried and then calcined at 500oC for 1 hour. The resulting Al2O3 nanoparticles were analyzed using XRD, FTIR, and TEM. Nanofluids were prepared from these nanoparticles by dispersing them into the water as a base fluid. Nanofluid characterization was carried out through Critical Heat Flux (CHF) measurements. According to the XRD data, the Al2O3 nanoparticles produced were gamma-alumina with a crystallite size of 4 nm. The BET specific surface area was 302 m2/g. From the TEM image, it was known that the nanoparticles formed a cluster of rod-shaped particles. FTIR data shows the presence of OH groups on the surface of the nanoparticles. The Al2O3 nanofluids made were known to be stable with an average zeta potential of 54 mV. Compared to water, the CHF enhancement of this nanofluid increased by 111%. The nanofluid has the potential to be used as a cooling fluid for ECCS, RVCS, refrigeration, and metal machining process.

Abstract
Numerical convection and diffusion models can be used to predict air pollutant concentrations in an area. Changes in air pollutant concentration can be analyzed using diffusion equations which depend on the coefficient of intra-particle diffusivity (D). Whereas to find out the changes in air quality categories become polluted using a convection equation which depends on the diffusivity coefficient between particles (Γ). The combination of the two equations can be used to estimate the polluted areas of a region. The results of the climate analysis indicate that Banten Province if viewed from the direction of the wind, is very potential for the development of increased fish production. Meanwhile, if viewed from the temperature and rainfall of Banten Province the potential for agriculture. However, considering that in the western part of the region there is a large industry with a chimney height of 275 meters, so based on atmospheric stability, the distribution of air pollutants spread far outside the industrial area. This will have implications for other regions so that at high concentrations (with diffusion equations) it will change the air quality (with the convection equation) so that in certain regions and at certain times it will become a polluted area.

Abstract
The presence of online transportation modes is a manifestation of the rapid development of information technology, especially smartphone and apps technology. Because of the critical issues of safety, service quality assurance and effectiveness of load factor to its capacity, online transportations in Indonesia cannot be classified and regulated as public transportation. The main function of online transportation is actually as a short distance feeder to public transportation. Unfortunately, because the public transportation is not adequate, so the online transportation functions slowly become informal public transportation mode. This in the future can cause problems in a city, especially when the increasing number of online transportations will rise the vehicle traffic together with private vehicles. To understand and prevent this problem becoming bigger in the near future, the mode choice between private vehicles and online transportations requires to be studied first. The purpose of this research is to obtain a reliable model of modal choice between private vehicles and online transportation by comparing the multinomial logit (MNL) probability method with the Artificial Neural Network (ANN), to study the accuracy of the performance of the two models for the mode selection between private vehicles and online transportation, and to evaluate the socio-economic factors underlying the mode choice between private vehicles and online transportation in the city areas of Banjarmasin and Banjarbaru.

Abstract
Constitutional Reform after fall of Soeharto-s New Order bring new direction for judiciary. Constitutional guarantee of judicial independence as regulated in Article 24 paragraph (1) of the 1945 Constitution, closing the door of dark memories in the past. In addition, in Article 24 paragraph (2) of the 1945 Constitution decide the Judiciary is held by the Supreme Court and the judicial bodies below it and a Constitutional Court. Such a strict direction of regulation plus the transformation of the political system in a democratic direction should bring about the implementation of independent and autonomous judicial powers. But in reality, even though in a democratic political constellation and constitutional arrangement that affirms the guarantee of independence of independence, in reality it does not represent the actual situation. There some problem which still remains, such as (i) the absence of a permanent format regarding the institutional relationship between the Supreme Court, the Constitutional Court and Judicial Commission, and (ii) still many efforts to weaken judiciary through many way such capturing judge. Referring to problem above, then there are gaps between what “is” and what “ought”, among others, First, by changes political configuration that tend to be more democratic, the judiciary should will be more autonomous. But in reality, various problems arise such as (i) disharmony in regulating the pattern of relations between judicial power actors, (ii) various attempts to criminalization judges over their decisions, (iii) judicial corruption. Second, by constitutional guarantee of independence of judiciary, there will be no legislation which reduced constitutional guarantee. But in reality, many legislation or regulations that still not in line with constitutional guarantee concerning judicial independence. This paper reviews and describes in depth about how to pour out and implement constitutional guarantees of judicial independence after the political transition and conceptualize its order to strengthening rule of law in Indonesia

Abstract
The series of Lombok earthquake started from July 2018 followed by two mainshocks and thousands aftershocks caused massively damage to the public facilities and residential areas. As a result of the earthquake measuring 6.9 SR, most of the wells were also damaged due to liquefaction. The most devastated areas usually have several units of lithology, namely: coastal sediment alluvium and pyroclastic rock. This research was conducted to characterize subsurface geological condition including groundwater aquifers using 2D resistivity tomography. Series measurements of 2D resistivity tomography at the some impacted area of 2018 Lombok Earthquake can reveal the relationship among the most of devastated area, the subsurface geological condition, the vibration, and also the most impacted liquifaction area. The most of impacted areas caused by 2018 Earthquakes lie on the very loose sand and shallow aquifer zone. The resistivity tomography, however, shows that in the North Lombok area usually has high resistivity thin layer (with a range of> 500 Ohm.m) around a depth of 10 m. This high resistivity layer is carbonate reef layer which may play a role as barrier of soil liquifaction especially when the earthquake’s wave vibrates the soil.

Abstract
Sunlight consists of ultraviolet (UV) light and based on its wavelength, the UV light could be categorized into UVA, UVB, and UVC. UVA has the longest wavelength of 320-400 nm and causes skin cancer in the epidermal layer. On the other hand, UVB with a wavelength of 290-320 nm gives an effect on the epidermis and dermis layer causing the skin to burn. Organic Ultraviolet (UV) filters can be found in plants and fruits which have orange-red or pink colours, such as watermelon, tomato, secang (Caesalpinia sappan), carrot, dragon fruit, faloak (Sterculia quadrifida R.Br), strawberry, papaya, and rosella. Most of these plants contain active compounds such as carotenoids and anthocyanin. Determination of the effectiveness of the extracts as potential sunscreen was carried out by determining the Sun Protecting Factor (SPF) value in vitro by UV spectrophotometry. Maceration technique was used for the extraction process by using ethanol with a ratio of 4:1. Each of dried extract (100 mg) was then mixed well in the ethanol (96%, 50 mL) until all the extract was dissolved and then filtered. The absorbance of each extract was measured in the wavelength range of 290-320 nm and the interval was set at 5 nm. The SPF values were determined by the Equation of Mansur. It was observed that all of the red pigmented extracts showed UV protection capabilities, with secang extract gave the highest SPF value of 18.490. Therefore, the secang extract would have good potential to be developed as one of the ingredients in the sunscreen cream. Sunscreen cream combination between secang extract and ZnO showed good quality and significant SPF value than ZnO and extract secang sunscreen cream.

Abstract
Introduction: Hypertension is a risk factor for cardiovascular disease. The blood pressure control through regular physical activities is necessary to prevent complications. Social support is one of the factors that affect the physical activities of people with hypertension. This study aims to identify the correlation between social support and physical activities of people with hypertension. Method: This study used correlational method with the cross-sectional approach. 110 people were chosen as participants using simple random sampling technique. A questionnaire asking about support from family, health workers, and peers, as well as International Physical Activity Questionnaire were used to collect the data. The statistical test conducted was Gamma Correlation Test. Results: Results show that there was no relationship between family support, health worker support, and peer support with physical activities among people with hypertension aged 45 years and above indicated by the p-value for each variable: 0.655, 0.055, and 0.857. Based on the three p-values, the support from health workers had a p-value close to 0.05. Conclusion: No correlation between social support and physical activities of the people with hypertension signifies that social support has not yet been able to be given adequately to the people with hypertension. Family, health workers, and peers are expected to strengthen their role in controlling the blood pressure of the people with hypertension through physical activities.

Abstract
In Indonesia, bandwidth usage management in higher education is still a great challenge. Every year, the internet bandwidth and the budget are higher, but the growth of scientific publication to the cumulative universities is still under the other countries in ASEAN. In the other side, the universities have not measure the effective of usage bandwidth for their activities. The log data is managed rarely. The user and data can be clustered. So the management have the picture for their bandwidth policies. In this paper, there will be comparing the clustering that using Agglomerate, K-Means, and K-Means algorithms. The results is to find the best clustering and make a pattern for ITB network usage. The method is implemented in real data in ITB network. The campus management will have a good data and information for their policies of bandwidth management.

Abstract
The Special Region of Yogyakarta is one of the most visited regions for recreational purposes in Indonesia. One of the most visited recreational areas is Baron – Pok Tunggal Beach District, where Sundak Beach located. Based on Yogyakarta-s Department of Tourism, the amounts of visitors of Baron – Pok Tunggal Beach District has increased from 518.899 in 2013 to 2.224.656 in 2017. At July 2018, Sundak Beach was damaged by the high waves as the result of heavy rains, causing the seagrass and corals ecosystem disturbed and damaged. The high waves also damaged the settlement and recreational area around the beach. The purpose of this study is to determine and evaluate the land carrying capacity of Sundak Beach as a coastal recreational destination. Evaluation of Sundak Beach land carrying capacity will be determined by calculating the land suitability and capability as a coastal recreational site. Based on the measurements and observations, Sundak Beach-s suitability as a coastal recreational area is 64,28% (quite sufficient as a coastal recreational area) with a rather good land capability with few limiting factors. The result of this study may provide a suggestion for the development of coastal management by the government and the local community.

Abstract
Net Interest Margin (NIM) can be seen as the profitability of a company. The higher the NIM, the higher the profitability of the company. However, NIMs can also be seen as bank inefficiencies. Higher net interest margin can reduce potential savers because of the low rate of return on deposits. In addition, this also increases the cost of capital for debtors, thereby reducing the potential investment and economic growth. During the period 1997 to 2005, showed that the average NIM in Indonesia was the highest among other countries in Asia. Central Bank of Indonesia is trying to reduce lending rates and reduce the NIM level to a reasonable level. However, the bankers think that the NIM level in Indonesia cannot be compared to other countries due to inflation and geographical conditions. This study analyzes several factors that influence NIM, including market structure, bank management performance, and risk factors faced by banks. This study uses multiple linear regression with panel data to see the effect of independent variables on the dependent variable. This study uses panel data regression analysis. The results show that NPL has a significant negative effect on NIM. Total asset has a positive and insignificant effect. LDR has a significant positive effect. BOPO has a negative and no significant effect. Equity to total asset ratio has a significant positive effect. And required reserve has a significant negative effect on NIM .The results of this study are expected to be a consideration for Central Bank of Indonesia, as the banking authority to determine the level of NIMs in Indonesia. In addition, this research is expected to be able to increase the banks insight to be able to control the factors that influence the NIM.
