Kebutuhan manusia akan energi fosil makin meningkat salah satunya penggunaan kompor gas, dan cadangannya pun berangsur menipis setiap tahun, tanpa diimbangi dengan sumber daya baru dari energi fosil dikarenak an membutuhkan waktu yang sangat lama. Untuk menanggulangi masalah ketergantungan manusia terhadap sumber energi yang tidak dapat diperbaruhi maka digunakan energi alternatif ya…
37 steel is a steel that has a low carbon content. The problem that often occurs in steel is corrosion. There are various ways that are done in reducing the corrosion rate in metals, one of which is the addition of corrosion inhibitors and coating. Rice husk ash is one type of ash used as a corrosion inhibitor because it contains tannins. Tannins are complex compounds used as inhibitors to …
At this time a lot of heat energy is wasted or just ignored and considered as an activity from devices that are often used, this condition certainly attracts attention to be utilized/used in empowering wasted heat energy, therefore it is necessary to utilize energy the heat of this fish grill to become electrical energy using TEC. The working principle of the TEC is that the heat pump phenomeno…
This study aims to determine the engine performance and capacity of the elephant grass chopping machine on animal feed chopping machines by varying the number of blades and their speed. In this study, there were 2, 3, and 4 blades. The speeds are 750 rpm, 850 rpm, and 1100 rpm. The results of the study showed variations using 4 blades resulted in the highest chop, which was 93.7 kg/hour. Variat…
The dominant electric stove used today has a weakness, namely the heating element in the form of a wire. For this reason, it is necessary to make an effort to increase the performance of the electric stove, the effort made is to add supporting equipment in the form of reflectors and Fresnel lenses on the solar cell. the added supporting equipment serves to increase the voltage and current recei…
Composite technology continues to develop with the use of natural fibers (Natural Fiber). One of the natural fibers that are quite abundant in Indonesia is sugarcane fiber. This study aims to make a composite board made from sugarcane fiber which is treated with alkali and bonded by polyester resin. In this study, the alkali variations were treated with values of 0%, 10%, 20% and 30% and the co…
Solar energy is used as a potential alternative energy source, especially seen from the source that emits energy in very large quantities and takes a long time. Solar energy is converted into electrical energy using solar panels. The performance of the solar panel depends on the surface temperature of the panel because the semi-conductor material in the panel is very sensitive to temperature ch…
