Abstract

Choosing a good conductor is still a problem. This is due to many factors including the cost and time required as well as expensive facilities but so far to determine the quality of materials accurately and effectively in a simple way has not been carried out except through complex laboratory tests such as through photo electrons and mechanical tests of materials which are expensive. . It is possible by the principle of heat dissipation in the conductor which as an alternative to the new test method is estimated to be low cost. Tests with the heat dissipation method on the conductor can be seen macroscopically that the conductivity is very influential in the conductor because it involves the speed of electrons contained in the conductor, if the conductor has a small resistance then the conductor has a high conductivity speed or in other words that the conductor has a high resistance. Small is a good conductor material used as a conductor.

Abstract

The need for electrical energy in Indonesia is increasing every year so other alternative energy sources need to be found. Waste is a major problem for residents of many cities, along with the rate of population growth which has an impact on the increasing amount of waste generated. To explore the potential of new renewable energy, namely the construction of a Waste Power Plant (PLTSa). Potential of waste energy in Jatibarang Landfill sourced from 16 sub-districts of Semarang City Region has a large amount of waste production, so that in this study research needs to be done on the use of waste as an alternative energy source to be utilized as Renewable Energy (EBT) to be managed into electrical energy that is useful for the community. From this study the electrical energy that can be utilized for PLTSa in 1 year for the next 5 years (2017 - 2021) is 84,627.02 Mwh / year in 2017, then 82,308.43 Mwh / year in 2018, after that 83,627.97 Mwh / year in 2019, then 83,179.35 Mwh / year in 2020, and finally 83,434.88 in 2021. The average output power of generators is 9,525.63 kW as potential electrical energy from waste waste.

Abstract

Kapal tangker memerlukan sumber daya listrik darurat yang handal untuk mendukung operasi peralatan kunci, termasuk navigasi, komunikasi, penerangan, sistem kemudi darurat, pompa kebakaran darurat, dan pengisian baterai. Dalam penentuan kebutuhan daya generator darurat untuk kapal tangker, dilakukan perhitungan teliti, termasuk faktor start-up yang signifikan. Hasil analisis menunjukkan bahwa total kebutuhan daya listrik darurat adalah sekitar 79,84 kW, dengan mempertimbangkan faktor start-up, total daya yang dibutuhkan adalah sekitar 128,64 kW. Generator darurat yang dipilih harus memiliki daya output minimal sekitar 128,64 kW. Sebagai solusi, generator darurat Volvo Penta tipe D9 MG / UCM274H-1 dengan daya 136 kW atau 170 kVA dan beroperasi pada 1500 RPM sesuai dengan kebutuhan daya listrik yang telah dihitung. Dengan pemilihan yang cermat, kapal tangker dapat memastikan kelangsungan pasokan daya listrik yang andal selama situasi darurat di laut, meningkatkan keamanan dan kesiapan operasionalnya.
