Abstract

The testing of desalination equipment is based on the increasing level of human need for the use of clean water. Improvement methods continue to be carried out with the aim of increasing the yield of clean water from desalination equipment. This research was conducted experimentally by providing a copper collector in a desalination device with a harpan to make it easier to absorb heat so that the water in the evaporator expands faster. By providing a variable difference in glass thickness, it is hoped that it can provide information that a good glass thickness can be applied to desalination equipment. The variation of the glass thickness is 4 mm and 5 mm with the same glass surface area. The results show that glass with a smaller thickness will make the desalination tool faster in absorbing heat energy. However, some conditions may also be considered to avoid damage to the glass. With the wind speed on the fourth day of testing which is 5.67 m/s and strong solar intensity reaching 397.14 W/m2, the energy absorbed by the collector reaches 3.72 kW/day on a glass thickness of 4 mm. Meanwhile, at a different thickness of 5 mm, the energy absorbed by the collector only reaches 2.72 kW/day. This shows that the difference in glass thickness plays a role in determining the occurrence of conduction heat transfer from outside the evaporator into the evaporator chamber.

Abstract

The number of motorized vehicles increases from year to year, the exhaust gases generated from these motorized vehicles cause air pollution by 70 to 80 percent, so efforts need to be made to control exhaust gas emissions. Considering the danger of exhaust gas emissions, the effort that needs to be made to control and reduce air pollution is the engineering and modification of the exhaust gas lines. Engineering and modification of exhaust gas lines, namely by innovating the exhaust by adding aluminum scrap. Researchers will conduct experiments and manufacture of tools and initial testing on motorized vehicles to see and observe the composition of exhaust gases produced from standard exhausts. The elements to be observed are the CO value, HC value, and CO2 value as comparison data. The tool that will be used to observe and see these elements is the Gas Analyzer. From the results of testing and analysis, data on exhaust emission tests with an average engine speed of 4000 rpm, and with an exhaust pipe temperature of 40 oC to 45 oC, were obtained. After testing the standard exhaust, then testing the modified exhaust and the addition of scrap 60 gr, 70 gr, and 80 gr aluminum obtained the best conclusion to reduce the danger of exhaust emissions from the modified exhaust added 60 gr aluminum scrap and when compared to the exhaust. the standard CO yield fell to 11.7%, HC fell to 4.26%, and CO2 fell to 1.59%.

Abstract

The ability of a pump to drain or move a certain amount of fluida / fluida that comes out through the pressure side of the pump in units of time volume is also called the capacity of a pump. Meanwhile, the pump head is the energy per unit weight that must be provided to flow the planned amount of liquid according to the pump installation conditions. A centrifugal pump is a pump that moves liquid by utilizing the centrifugal force generated by the impeller ratation. The results of data calculations and graphic analysis on the effect of variations in the impeller entry angle on the impeller with exit angle (?2) = 250,standard pump impeller,and impeller with exit angle (?2) = 350 on the performance of the centrifugal pump can be concluded, namely the performance value of centrifugal pumps. The highest is the impeller with exit angle (?2) = 250 where the specific speed value produced is 192.52 rpm and the efficiency level of this impeller is 6.82%
