Abstract
Sleep disorders is a disorder experienced by a person when the REM and NREM cycle don-t work normally. Prolonged sleep disorders can cause a variety of bad conditions such as depression, fatigue, reduce work, performance and endurance. It quickly offended till affect to our own safety. The latest study in 2018 conducted by Dr. Welly Sondakh, MPH in Jakarta revealed that there were 10% of people with insomnia from the Indonesian population or around 28 million people. The low public awareness of sleep disorders causes them to need alternative media, namely an expert system to diagnose sleep disorders. Expert system is a system that uses the knowledge of an expert to solve a problem in a particular field where the system is not limited by time and can be used by many people. The method used in this system is Certainty Factor as an inference engine to determine the results of the diagnosis based on the symptoms determined. The calculation of this method combines the MB (measure of increased belief) and MD (measure of increased disbelief) values obtained from experts. From 50 test data, 45 data were obtained so that the accuracy level reached 90%. This shows that the expert system of diagnosing sleep disorders is suitable for early diagnosis of sleep disorders

Abstract
Silicalite-1 is a type of zeolite with no aluminum content and is hydrophobic. This zeolite can be synthesized from various types of silica. Elephant grass (Pennisetum purpureum) is one of the potential agricultural wastes that has a fairly high silica content that can be used for zeolite synthesis. In this study, silicalite-1 zeolite was synthesized using silica extracted from elephant grass and tetrapropilammonium bromide (TPABr) templates. Silica samples extracted from elephant grass have 71.91% amorphous SiO2 content. Silicalite-1 zeolite was synthesized with mole ratio of 1SiO2 : 0.527TPABr : 0.395Na2O : 98.45 H2O, using hyrothermal method at 180°C for 24 hours in a stainless steel-teflon lined autoclave. The resulting silicalite-1 samples were confirmed by X-Ray Diffraction (XRD) and showed 2θ which was typical for silicalite-1 i.e. 8.02°, 8.93°, 23.09°, and 23.98°. The results of Scanning Electron Microscopy (SEM) show that silicalite-1 zeolite has hexagonal crystals with 43.36 µm size as a result of the calculation using the Schrerrer method.

Abstract
MgH2 is one of the most promising material for hydrogen storage application, since its reversible and able to store hydrogen in large amounts of 7.6wt%. In this study, nickel and silicon oxide catalysts were used to reduce the operational temperature of MgH2. The silicon oxide used in this study was extracted from rice husks ash. The composition of MgH2 + 10wt% SiO2 + 5wt% Ni was prepared by mechanical alloying technique, by varying milling time 1, 5, 10 and 15 hours. XRD results indicate a decrease in particle size with longer milling time. MgH2 was obtained as the main phase followed by Ni and SiO2. SEM results showed that the longer milling time, the more particle size is homogeneous. Furthermore, thermal investigation using DSC showed that the desorption temperature obtained was in the range of values of 331,8 0C to 342,3 0C. The addition of 10wt% SiO2 and 5wt% Ni have improved sorption temperature and kinetic of MgH2.

Green Supply Chain Management (GSCM) is an operational initiation to overcome environmental problems that many organizations experience, including Small and Medium Enterprises (SMEs). This study aims to determine the effect of the industrial environment on GSCM implementation and its impact on organizational performance in food and beverage SMEs in the East Java province, Indonesia. The survey and interviews were conducted with 76 Food and Beverage Association members. The variables studied included the industrial environment, GSCM, and organizational performance, and decentralization in moderating GSCM towards Organizational Performance. Data was analyzed using Partial Least Square (PLS). The results show that the Industrial environment has a significant effect on Organizational Performance, but does not have a significant effect on GSCM. GSCM does not have significant effect on Organizational Performance. However, decentralization was not able to moderate the influence of the Industrial Environment on Organizational Performance. The nature of the centralized authority on SMEs needs further testing given that such rapid environmental changes certainly require a rapid response in anticipating the speed of market changes. Also, how should the influence of a decentralized organizational structure on SMEs in various countries or in the country with foreign ownership, need to be investigated further.

Abstract
The Surabaya IV Regional Construction Services Center (BJKW IV) is an Organizational Unit under the Ministry of Public Works and Public Housing. One of the main tasks is the management of Non-Tax State Revenues. BJKW IV Surabaya has the assets of the Hall, Mess/Dormitory and Classrooms which can be used for internal activities and leased to private institutions related to construction services. However, the rental rates of the above building assets that are still used Government Regulation Number 38 of 2012 cannot meet operational and maintenance needs. This study aims to establish the latest rental rates that are able to meet operational and maintenance needs. In this paper, the analysis of rental rate determination uses the method of Activity Based Costing (ABC). The results show that the tariff requirements to meet operational and maintenance requirements are as follows: Hall rental rates is 1.15 times the original rate, Mess/Dormitory Rooms rental rates is 2,75 times the original rates, Large Classes rental rate is 2,25 times the original rates and the Small Class Room rental rate is 1,85 times the original rate. Based on the results above, BJKW IV Surabaya needs to consider tariffs for commercialization to the private sector.

Abstract
Enuresis, also known as bed-wetting is a condition where the children at the age of 5 or more urinate on the bed or on their clothes, and it happened often about at least twice a week for 3 months in a row. This research is dedicated to studying the relation between toilet training, physical and family history with the incident of enuresis in children between 5 and 6 years old. A cross-sectional study was conducted in North Denpasar District. The samples were 105 subjects whose study at kindergarten and their parent. Data of the risk factor of enuresis were collected by using questioner and then analyzed by chi-square and Fisher exact test. The result of this research are children who had parents with enuresis history (PR = 3,720), children who had siblings with enuresis history (PR = 4,950), breastfeeding history (PR = 1,920), duration of breastfeeding (PR = 2,133), toilet training (PR = 5,497), and bad physiological history (PR = 1,915) were related to incident of enuresis in children with p-value <0,05. Based on the result, parents, educators, or medical personnel may prevent the incident of enuresis by avoiding the risk factor of enuresis.

Abstract
Wastewater needs to be processed before being disposed. Generally the wastewater that produced by a hospital contains a lot of bacteria, viruses, chemical compounds, and drugs which can be harmful for the health of the surrounding community. For this reason, it is necessary to process hospital wastewater by using effective and efficient wastewater treatment technology. One of the processes of wastewater treatment is biological processing that use microorganisms. Aim of this study is to isolate microbial that produce proteolytic capabilities that are potential in treating hospital wastewater. This research is a descriptive study with cross sectional design. Samples were taken from the Waste Water Treatment Plant of Kasih Ibu General Hospital in Denpasar. The screening of the proteolytic bacteria was done by growing the isolated culture on skim milk agar. The colonies that produce clear zone were identified as proteolytic bacteria. In this study a total of 43 isolates were obtained and two isolates showed their proteolytic activity. Both isolates are Gram positive cocci and Gram negative bacilli.
