Bondan Hamlet is a hamlet in Kampung Laut District, Cilacap. One of the community's problems is the lack of clean water and the PLN electricity network. In 2020, a desalination facility named Sidesi Mas will be built in Bondan Hamlet with a capacity of 240 liters/hour and using the reverse osmosis principle. The energy source for desalination uses a solar power plant (PLTS). Desalination management requires economic analysis, especially in determining the selling price of desalinated water. The cost of producing desalinated water can be calculated using the Cost of energy (CoE) value of the PLTS or the costs incurred to produce electrical energy per 1 kWh. To get the PLTS CoE, this article discusses a simulation to analyze the performance of PLTS desalination systems with Homer software. Homer performs analytical calculations based on a location input, solar energy potential, capacity, and costs of PLTS components as well as electrical load data. The simulation results show that PLTS energy production is 535 kWh/year, the CoE value is IDR 21,975/kWh and the production cost for producing clean water is IDR 183.13/liter.

The increase in greenhouse gases in the form of CO2 gas as vehicle exhaust emissions contributes to climate change. Technological approaches and alternative fuels continue to reduce fuel consumption, but this is not enough. Another method is to use eco-drive behavior, one of which is related to replacing the air filter. This study is purposed to provide guidelines for motorized vehicles operating in selected areas in Lampung Province in the behavior of eco-driving. The results of the fuel consumption test using the full-to-full method found that at each filter distance (8,000 km, 12000, and 16,000 km), vehicles operating in Mesuji with the highest deficiency, followed by Tanjung Bintang and Krui areas. In line with eco-drive behavior, for vehicles operating in Mesuji, the air filter replacement period must be faster than the other two areas, followed by Tanjung Bintang and Krui.

Assets are resources owned by an entity. Cilacap State Polytechnic is a higher education institution that has many assets. Current asset maintenance and repair services are still carried out conventionally. Each work unit must fill out a maintenance and repair proposal form and then submit it to the Maintenance, Repair, and Maintenance Unit (UP3). The proposal will be recorded and scheduled to be followed up by the Technician. The problem that occurs is that the proposal form is often scattered and even lost so the response time is often slow. In addition, maintenance and repair schedules are often not ordered according to the time of the request. This has an impact on the abandonment of work in certain work units. The purpose of this research is to create an information system for the repair and maintenance of campus assets. In order for maintenance and repair services to be carried out according to the time of the request, the FCFS method is applied. Thus, the service process for maintaining and repairing campus assets becomes more organized, schedules (queues) are sequenced, and the response time for incident handling is faster.

Freshwater fish is a type of fish that is very popular with the wider community. The problem that often occurs in cultivators is the timing of feeding fish. This study introduces automatic pellet sowing with a DC motor as a pellet ejector. The method used is by identifying research variables. This research was conducted with 3 variations of DC motor rpm rotation with 2 different pellet sizes. The data obtained showed that the farthest ejection distance is 3 mm pellets with a rotational speed of 6000 rpm, while the closest ejection distance is 3 mm pellets with a rotational speed of 1000 rpm, and it is also concluded that the data findings are the estimated time to run out of 3 kg of pellets for each pellet sample with three variations of DC motor rotational speed. Pellets with the fastest time of 1.90 s are pellets with a size of 3 mm with a rotational speed of 6000 rpm, while the longest time is 5.2 s, namely pellets with a size of 1 mm with a rotational speed of 1000 rpm.

The OSIS chairman is the highest leader in the OSIS management structure and is accompanied by a vice-chairman. Therefore, a selection with several criteria is needed to determine the best candidate. Things that are considered in this selection are realism, maturity, organizational experience, public speaking, discipline, character, organizational activity, and responsibility. By utilizing a decision support system, the best candidates are obtained for the candidate for chairman and vice-chairman of the student council. This system is made with the method used to assist the selection process, namely, profile matching. Profile matching is used to find the profile of a job that is sought from a predetermined specification. This method provides a solution and has a clear objective in decision-making. On the other hand, the method used to develop a decision support system is the incremental method. The selection of the incremental method is based on the fact that this method has an iterative nature, which can adapt to the many repetitions that occur during the development process. The novelty of this research is the recommendations generated from the developed decision support system. There are notifications about the results of decisions to users, in this case, the candidates for the OSIS chairman and vice chairman who are alternatives in the election process. This study resulted in recommendations in the form of candidates for OSIS chairman and vice chairman by the candidate's profile.

Solar panels such as PLTS can be an alternative to complete electricity needs. However, the intensity and temperature of the sun that can not be adjusted are an obstacle to the use of solar panels. Continuous absorption of sunlight can cause solar panels to overheat. Therefore, it is necessary to cool the solar panels, therefore the heat absorbed does not exceed the capacity. Phase Change Material (PCM) paraffin graphite is one of the coolants for solar panels. PCM paraffin graphite was used to coat solar panels and then measured for voltage, current, and temperature. The results were compared with solar panels that were not covered with PCM paraffin graphite. The test results found that solar panels coated with PCM produced a lower surface temperature of 0.1458% than those without PCM. Meanwhile, the efficiency and power produced by PCM-coated solar panels were 19.496% and 0.02685% higher than solar panels without PCM, respectively, so the use of PCM paraffin graphite in solar panels can increase their efficiency.

Many methods can be used by the community to burn coconut shells into charcoal, one of which is by utilizing appropriate technology fueled by diesel oil, namely shell powder processing machines. The production of briquettes from coconut shells is still limited and has not developed rapidly because the process of shelling coconut shells is still simple thus it takes three to five days. The use of adhesive amounts is not optimal. This is done to fulfill the community's desire; therefore, coconut shell waste can be managed as raw material for making briquettes to become a source of community income. The purpose of this research is to optimize the production of coconut shell briquettes by utilizing appropriate technology fueled by diesel oil. The method used is by conducting a trial process of starch adhesive treatment, namely 1%, 2%, 3%, 4%, 5%, 6%, 6.25%, and 7% with the amount of water 900 ml at a temperature of 70 0C to form gelatinization. As a result, it was found that the best starch adhesive treatment is in the 6.25% test with the ratio of the starch adhesive mixture, shell powder, and water being 0.25: 4: 0.9. It indicates that the resulting briquette shape is more efficient, has high density and small briquette pores.

A more quantifiable perspective is assuming the role of mechanistic management in an effort to enhance business based on its capacity to transform data into knowledge and insight. The industry has not completely supported its business strategy also with driven data. Using a transaction dataset taken from one of the Kaggle.com challenges, this experiment attempts to determine consumer spending patterns and Retail Fashion business revenues (H&M Personalized Fashion Recommendations). The results of the experiment are the number of transactions based on customer age, the most sales product and one-time purchased item, and the type of product that generates the highest and smallest income. The approach employed is EDA using the Python language. In order for businesses to generate analytical findings that provide future perspectives and to help identify the gap by delivering analytical results in the form of suggestions that can be perpetuated, the findings of this experiment are intended to support the capabilities of simulation. The challenge in this experiment is the abundance of datasets, which necessitates a suitable operating environment.
