In order to minimize the effect of transmission on infectious diseases and optimize the layout of the facilities, it is necessary to improve the layout of the facilities (re-layout) of the existing Public health center services. So far, Public health center services are still very irregular, such as the distance from general medical centers to other medical centers. The purpose of this research will be to produce a new facility layout for the Public health center, so that it can optimize employee performance and the layout of the facility. In this study, the layout of the facility was redesigned using the Activity Relationship Chart (ARC) And Material Handling Costs are used to determine the distance between rooms and to estimate degree of closeness between rooms, the results of this study are two layout designs aimed at puskesmas which aim to approach the treatment center and pharmacies as well and keep the ISPA room away to minimize the spread of COVID-19 disease.

This research is categorized as quantitative research using Partial Least Squares-Structural Equation Modelling (PLS-SEM) technique method. Data collection technique were obtained through online questionnaires involved 100 respondents of Learning Management System (LMS) users. The questionnaires were assembled based on 21 instruments which were indicators in this study. The results shows that compatibility does not have a significant effect on perceived usefulness, but it has a significant impact on perceived ease of use. Perceived ease of use has a significant influence on perceived usefulness. Perceived service quality and perceived usefulness have an effect on behavioral intention while perceved ease of use does not have an impact on behavioral intention. Perceived usefulness was simultaneously affected by 50.2%, perceived ease of use was affected with 10.8%, and the behavioral intention variable was simultaneously influenced by 19.2%.

This is done to increase the added value of natural gas products. Natural gas exports must be reduced and converted into exports in the form of derivative products. Methanol, ammonia, urea, ammonium nitrate and soda ash are derivative products from natural gas that need to be developed. These product derivatives are used as a mixture of raw materials in various industrial sectors that are closely related to daily needs, so that the market and prices will not decrease. Methanol provides added value up to 4.1 times, Ammonia up to 7.2 times, Urea up to 12.2 times, Ammonium nitrate up to 16.2 times and Soda ash up to 8.7 times.

With the BPJS and complete facilities, the Puskesmas is now almost the favorite of the people to get health-related consultation and treatment. So this study tries to make an analysis of puskesmas services and evaluate the layout and queues in the puskesmas using Promodel simulations. The simulation is used because of the fluctuating number of patients who come every day, so that with the simulation the process of estimating patient arrivals can be carried out using statistical distribution estimates. The results of this study indicate the need for a new layout change, where with this new layout the patient's time in the system can be reduced and the need for adding doctors to 2 to 3 people to cut the number of queues that have accumulated waiting to be examined by a doctor. If the point of adding doctors cannot be met, then the puskesmas can provide adequate wai...

So it is necessary to use technology to minimize the cost of re-layout. Simulation is one solution that can be applied in solving problems related to layout improvement. The SAMSAT XXX office experienced a very heavy queuing problem, so it was necessary to improve the layout by changing the position of the service office. By using the modeling system, the STNK tax service system can be created in a virtual system and a new layout is created using the promodel. The results indicate the need for additional registration counters from the initial one consisting of only one counter to three counters, and this has the effect of increasing the productivity of payment counters and delivery counters by up to 15%. So that the productivity burden of the three counters at the SAMSAT XXX office has the same load.

This is allegedly due to the incomplete professionalism of the Bureaucracy and the Development of Human Resources at the West Java Regional Secretariat for Basic Social Services. Lack of Employee Performance can be seen from several indicators, namely: the accuracy of low quality work, low work cooperation and low employee work attitudes. Based on these facts, the allegations arise because of bureaucratic professionalism and optimal human resource development. The research method used was an explanatory survey, using a quantitative approach through Path Analysis. The results showed that the professionalism of the bureaucracy and the development of natural resources had a significant influence on the performance of employees at the West Java Regional Secretariat of Social Services.

Almost all people in Indonesia today, if they want to do treatment or referrals, they must go to the puskesmas. So this study tries to analyze the services of the puskesmas and evaluate the queues in the puskesmas using the Promodel simulation. Simulation is considered as a suitable tool for analyzing service queues at puskesmas. The results of this study indicate the need to increase the number of doctors to 2 to 3 people to reduce the number of queues that accumulate waiting to be examined by a doctor. If the additional doctor points cannot be met, then the puskesmas can provide adequate waiting room facilities for patients to be examined by a doctor, the ideal number of waiting room seats for patients waiting to be examined by a doctor is 38 seats.
