This research aims to; 1) Designing and making aluminium melting crucible casting with the capacity15 kg; 2) Conducting the test of chemical composition of the first and second melting result. Theresearch used field and library research. From the result of the design, it could be obtained that thedimension of melting casting has 547 mm diameter, 3 mm thick, 410 mm high. Whereas, molten cup has 178 mm diameter, 8 mm thick, and 230 mm high. The result of the first melting chemicalcomposition test and the second one do not work out a significant change. The material of the firstmelting result still contains 89,52% of aluminium (Al), while the main fusion is 7,71% of zinc (Zn)and 1,84% of silicon (Si), and in the second melting result still contains 89,55% of Alumunium (Al),while the main fusion is 7,51% of zinc (Zn) and 1,94% of silicon (Si).

Nowdays, Alumunium is widely used and utilized in industrial activities because of light properties and having well mechanical strengths. The use of alumunium does not only limit on the use of new alumunium, but also the used one. The main purpose of this research, i.e., (1) testing of physical and mechanical properties of Al-Zn7 from the fussion of Crucible furnace; (2) analyzing crucible furnace of the Al-Zn7 fussion by comparing to the result of the first and second fussion. The method of this research was experimental research with the average value of each the first casting was 49,2 HRB and the second one was 50,3 HRB. Based on the test result showed that the quality of crucible furnace was good because it did not experience the significant changes.

The vehicle's suspension system have function to reduce vibrations from the shock between the wheels and the road. Previous research discussed the simulation of spring loading with material variations. This research focuses on the design and analysis of springs that will be used in Electric Motorbikes (SEMOLI). Spring analysis between cast stainless steels and carbon stainless steels is done by calculating displacement transmissibility. The analytical method used is the SDOF harmonic method to determine the system response. The results of the analysis are considered for the selection of springs by determining the displacement transmissibility and the response of the suspension system. The results of the analysis of the characteristics of cast stainless steels and carbon stainless steels for active springs 6, 7, and 8 at speeds of 10 km/hour, 20 km/hour, 40 km/hour, 80 km/hour showed a decrease in displacement transmissibility. Characteristics for stainless steel material at steady state condition with active spring 6 is 0.3 second, while 7 and 8 are 0.25 second. The characteristics of overshoot for cast stainless steel material with active spring 6 are 55.3%, 7 are 52.7% and 8 are 50.3%. Stainless steel material has the characteristics of overshoot on active spring 6 is 55.8%, active spring 7 is 53.3%, and active spring 8 is 51 From the characteristic analysis, the best material obtained is cast stainless steel with a smaller displacement value dan good respon.

The proper use of machining parameters in order to improve general quality is expected to optimize the results of the machining process including the use of the Taguchi experimental design. Several controlled parameters are carried out that are the cutting and feed speed, and cutting depth with three levels in the internal turning process of S45C steel material. Experiments were carried out using the Taguchi experimental matrix L9(34). The turning results are rounded and the variance and signal to noise ratio analysis are carried out in accordance with the proposed Taguchi design. The results obtained, the cutting speed and the identified cutting depth factors affect the roundness of the internal turning results. The results of the analysis of variance on the S/N ratio with smaller and better quality characters and based on hypothesis testing, is that the cutting speed and significant cutting depth parameters with a 90% confidence level affect roundness. The conditions of the cutting speed of 200 [m/min], the feed speed of 0.05 [mm/rev], and the cutting depth of 0.25 [mm] are the optimum parameters obtained.

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.
