Abstract

The outbreak of the Covid 19 disease has caused disaster to the people. The emergence of this disease’s outbreak encourages the importance clean lifestyle. In order not to easily contracted the Covid 19 disease, it is necessary to make automatic handwashing equipment to prevent people from having direct contact with the equipment. In this research the design and testing of an automatic handwashing equipment based on solar energy were carried out. The purpose of this research was to determine the capacity of the sun's intensity to provide electrical energy through the solar module to the battery which will be used to supply electrical energy of solar energy-based automatic handwashing equipment. The method used in this research was the Palh and Beitz method approach and the experimental method which started with the design, material selection, assembly and testing. The design produced equipment specifications for a solar module framework with a height of 100 cm, a width of 80 cm, a length of 100 cm, while for a sink frame with a height of 90 cm, a width of 45 cm, and a length of 55 cm. The test was carried out in three phases, phase one was testing the module input power. The module input power in the test produced a power of 2461 Watts with a solar radiation intensity of 3237 W / m2. The peak intensity and power of the sun was shown at 13.00 WIB. The second phase of the test was the length of time needed to charge the battery took 2.5 hours. The third phase of the test was the power needed for sensors and pumps of 358 Watts. The power requirement of 358 Watts could be supplied by a 100 Wp solar panel, since the power released from a 100 Wp solar panel is 400 Watts.

Abstract

Penegembangan energi hybrid terus dikembangakan mengingat kebtuhan energi terus meningkat. Sejalan dengan pengembangannya pemanfaatan energi alternatif menjadi solusi dalam mengatasi kebutuhan energi. Penelitian ini akan melancang dan membuat energi matahari sebagai suport energi listrik yang digunakan untuk sistem energi hybrid berbasis energi matahari dan energi hidro, dari hasil perancangan kerangka dudukan modul sel surya menghasilkan spesifikasi ukuran tinggi 100 cm lebar 67 cm dan panjang 90 cm, dari perhitungan didapat konsumsi energi listrik pompa 125 watt 32 liter/menit untuk mengisi tangki air sebesar 1000 liter adalah sebesar 66,7 watt, perhitungan daya solar sel sebesar 33,6 watt per unit maka jumlah modul sel surya yang dibutuhkan sebanyak 2 unit modul surya, perancangan modul sel surya di buat 3 unit sehingga 1 unit digunakan sebagai saving energi listrik. Hasil pengujian berdasarkan radiasi matahari maka intensitas radiasi matahari rata-rata sebesar 4916 (watt/m2) dengna daya sebesar 19,76 watt.

Abstract

Hybrid energy having continuous development considering the energy needs continue to increase. As the development continues, the use of alternative energy becomes a solution in overcoming energy needs. This research will be designig and manufacturing solar energy as a support for electrical energy used for a hybrid system based on solar and hydro energy. From the results of the design of the solar cell module holder frame, it produces specifications for a height of 100 cm, a width of 67 cm and a length of 90 cm, from the calculation, the pump electric energy consumption of a 125 watt32 liters / minute to fill a 1000 liter water tank is 66.7 watts, the solar cell power calculation is 33.6 watts per unit, so that the number of solar cell modules needed is 2, the design of the solar cell module made is 3 units, 1 unit is used as electrical energy saving. The test results based on solar radiation, the average solar radiation intensity is 4916 (watt/m2) with a power of 19.76 watts.

Abstract

This research aims to evaluate the feasibility of producing briquettes from rubber wood and rice husks as a step towards sustainable energy diversification. Qualitative and quantitative analyses were conducted on the raw materials, considering their physical and chemical properties as well as calorific values. The production process involves drying, grinding, mixing, compacting, and forming using simple technology. Feasibility study results show positive attributes of the briquettes, with low ash content at 1%, high calorific value at 5016 kJ, and low moisture content at 0.9%. Briquettes offer potential as clean and efficient energy sources. Economic analysis reveals an NPV of IDR 407,729 and an IRR of 20%, surpassing the 12% case of capital rate. Overall, this briquette production signifies a viable and sustainable energy diversification effort, contributing to environmentally friendly energy source development.
