Abstract

Electricity is a basic need for almost all human beings, electricity is the main requirement in all economic activities and human activities. The diminishing availability of fossil fuels requires alternative energy sources that can meet energy needs. In this research, a micro-scale power plant for street lighting was developed, using a vertical wind turbine. To obtain mechanical energy from wind power, a vertical wind turbine of the Savonius type was developed. A single phase rectifier is used to convert the generator's mains voltage into direct current which is supplied to the battery for energy storage purposes. An LDR (Light Dependent Resistor) based automatic switch is used which functions to turn on the lights when it is dark. With the alternative of using a wind turbine for street lighting, it has the advantage of being able to keep generating electricity 24 hours a day, as long as there is wind from the vehicles passing through it. After doing research, this wind turbine can produce a voltage of 12.2 volts at a wind speed of 3.85 m/s, suitable for use in small-scale power plants. This type of power plant can be further developed on a larger scale so that it can be utilized to supply electrical energy needs in areas that are still not covered by electricity

Abstract

Welding technology is an important process in the field of manufacturing in metal welding. SMAW welding uses electrical energy as a heat source and additional electrodes in joining metal welding. The angle of the electrode and the current strength greatly affect the welding strength. In this research, the design and analysis of variations in electrode angle and current strength in SMAW welding were carried out on tensile strength. The material used for testing is ST37 steel. The electrode angles used are 65o, 70o and 75o. The magnitude of the current used is 3 variations, namely 90 A, 95 A, and 100 A. In this research, the data processing method used is a factorial design with data from the results of tensile strength testing. In this study, the largest tensile strength test results were obtained at an electrode angle of 70o with a current strength of 100 A, getting a result of 32.668 kg/mm2, while the smallest result was obtained at an electrode angle of 65o with a current strength of 90 A, getting a result of 19.96 kg/mm2. The results of this research will be used as a reference for further research with variations in angle and current, using different test materials.

Abstract

Bioetanol merupakan salah satu energi alternatif yang terbuat dari tanaman. Ada tiga kelompok tanaman sumber bioetanol, yaitu tanaman yang mengandung pati, glukosa, dan selulosa. Kulit nangka memiliki kandungan karbohidrat yang didalamnya terdapat pati, glukosa dan selulosa. Dengan demikian, kulit nangka dapat dimanfaatkan sebagai bahan bioetanol. Penelitian ini bertujuan untuk menganalisa performa mesin motor 4 langkah yang menggunakan bahan bakar campuran bioetanol kulit buah nangka dengan pertalite. Campuran bioetanol kulit nangka dengan pertalite diaplikasikan pada motor dengan komposisi 10%, 20% dan 30% bioetanol kulit nangka. Pengujian dilakukan dengan putaran mesin yang bervariasi mulai dari 3000 rpm hingga 9000 rpm. Hasil penelitian menunjukkan ada konsentarasi bioetanol kulit nangka yang optimum untuk menghasilkan performa maksimal. Torsi tertinggi telah didapatkan ketika menggunakan campuran 20% bioetanol pada pertalite saat putaran mesin 6000 rpm yaitu sebesar 18,10 Nm. Pada penggunaan campuran bahan bakar 10% bioetanol dan 90% pertalite untuk putaran mesin 8000 rpm, diperoleh nilai daya sebesar 18,53 HP yang merupakan daya tertinggi. Sedangkan laju konsumsi bahan bakar terendah yaitu 2,80 L/jam diperoleh pada penggunaan campuran 30% bioetanol.
