Abstract

Penelitian ini bertujuan untuk menganalisa pemakaian daya listrik pada pompa air yang dihasilkan oleh pembangkit listrik tenaga surya portable, dengan memasang pembangkit listrik tenaga surya portable sebagai alat uji dan suplai energi listrik pada pompa air tersebut. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dan experiment, dimana dilakukan survei dan wawancara langsung ke masyarakat yang terdampak khusunya masyarakat Desa Toniku, kemudian melakukan advokasi data-data selanjutnya dilaksanakannya pemasangan solar panel portable pada pompa air, analisa dan pengujian. Hasil dari pengujin selama 5 hari, pengujian juga dilakukan pada malam hari, efektifitas pompa bekerja hanya sampai 1,5 jam setelah dari 1,5 jam pompa tidak lagi bekerja secara maksimal sampai pada menit ke 240, pompa tersebut masih tetap menyala namun tidak menghasilkan air sampai pada menit 450. Kinerja pompa mulai dari hari pertama sampai dengan hari ketiga, pada hari ketiga kinerja pompa berada pada nilai tertinggi yakni 25,038 Joule. Untuk memaksimalkan kinerja pompa air tersebut maka dibutuhkan penambahan 1 buah baterai dengan kapasitas 100 Ah,12 Volt. Agar dapat menggerakan pompa secara maksimal, efektivitas dari sinar matahari selama 8 jam yang diperoleh dari pada perhitungan sebesar 800 Watt, oleh karena itu untuk memenuhi kebutuhan daya dari baterai pada pemakain selama 8 jam sebesar 9.600 Watt. Maka besar dari daya baterai tersebut dibagi dengan total ouput dari solar panel sebesar 800-Watt maka dibutuhkan 12 panel surya dengan masing-masing ouput daya 100 Wp.

Abstract

This study aims to determine the effect of casting thickness and pouring temperature on the fluidity properties of used aluminum cans. In addition, this study was also conducted to determine the defects that occur in used aluminum can castings. The casting method used in this research is the lost foam casting method with variations in pouring temperatures of 670°C, 700°C and 730°C. and variations in the thickness of the castings, namely 2 mm, 4 mm, 6 mm and 8 mm to determine the fluidity value of used aluminum cans. Observations made are defects that occur in the castings. The results showed that in the thickness of the mold pattern with a temperature of 670°C, 700°C and 730°C fluidity increases with increasing pouring temperature. At a temperature of 670°C, the fluidity length is 38 mm, at a temperature of 700°C the fluidity length is 48 mm and at a temperature of 730°C the fluidity value increases to 113 mm. However, in addition to increasing the fluidity value, there are several casting defects that occur in the castings, namely, the occurrence of external shrinkage at 670°C, air cavities at 700°C, and pinhole defects at 730°C.

Abstract

Liquid smoke is a condensate liquid from the pyrolysis of coconut shells which contains the main constituent compounds of acids, phenols, and carbonyls, so it is widely applied as a natural preservative in food and provides sensory characteristics in the form of aroma, colour, and a distinctive taste in food products and as an anti-bacterial. The research objective was to design, manufacture, and test the liquid smoke distillation apparatus. The method used in this research is an experimental method where the activities carried out include designing, making, and testing. The result is that the furnace is made based on the results of the initial design with a height of 61 cm, width 41 cm and length 41 cm. The top of the furnace is conical with a cone height of 34 cm. The condenser tube is rectangular in shape with a width of 40.5 cm, length 40.5 cm and a height of 60.5 cm. the condenser tube serves to accommodate water which is used as a cooling medium. The inside of the condenser tube contains ¾ inch pipe which is formed into a rectangular spiral into 5 stacks. The pipe functions to flow the smoke from the combustion products from the gas phase into a liquid by cooling it with water as a medium. the manufacture of the liquid smoke distillation device has been carried out by the design, but there are some minor changes in the process of making the distillation device. Tests are carried out using raw materials, namely coconut shells and coconut fibers as fuel. Tests carried out with variations in the time and volume of liquid smoke generated from the distillation device. The test results from the liquid smoke distillation tool obtained 400 ml of liquid smoke from the distillation in 2 hours

Abstract

Pollution of plastic waste to the environment is a big obstacle because plastic waste is difficult to recycle directly. Waste management should implement processes, such as reduce, reuse, recycle and replace potentially waste items into Recycle (Replace) materials. Recycling plastic waste has the potential to change what was previously waste that has no economic value into an item that has economic value and at the same time reduces environmental pollution problems. The purpose of this study was to design a plastic waste chopper with a capacity of 85Kg. The method used in this research is the method of design and calculation. The results of the design of a plastic chopping machine with a capacity of 85Kg, the dimensions of the shaft length are 50cm, the shaft diameter is 8cm and the cutting blade holder is connected to the shaft. The blade is designed so that it can be adjusted forward and backward according to the thickness of the plastic to be chopped. There are 6 dynamic blades and 2 static blades. The cutting angle of the blade is 45°. The hooper design has dimensions of 40cm long, 40cm wide and 60cm high with a plate thickness of 0.8mm. The frame of the garbage chopper has dimensions of 40cm long, 40cm wide and 70cm high. The result of calculating the engine capacity on a plastic chopper with a capacity of 85kg hour is 1400g minute.

Abstract

The purpose of this study is to determine the effect of casting temperature variations on the hardness and microstructure of used aluminium cans. The casting method used in this research is the Lost Foam Casting method with a cast temperature variation of 670°C, 700°C and 730°C. Vickers hardness testing was carried out to determine the effect of temperature variations on hardness, microstructure observations were made to see what phenomena occurred. The results show that the hardness value with the lowest temperature of 670°C has a higher average hardness value in the Vickers test compared to the high temperature of 730°C. This shows that the pouring temperature rate of metal castings is more effective in metal recycling at 670°C for the hardness value in the Vickers test. Porosity decreases with increasing pouring temperature, seen at 670°C with a microstructure magnification of 100x the porosity is rather round and large on the surface of the castings. While at a temperature of 730°C with a magnification of 100x microstructure, it can be seen that the porosity is getting smaller in the form of dots scattered on the surface of the castings.
