Abstract

UD Arang Tempurung is a trading business engaged in the production of coconut shell charcoal and coconut shell charcoal powder. The sieving system is driven by a combustion motor which results in an unstable rotation. This affects the sieve yield and requires skilled personnel for treatment. The filter material is made of a material that is less corrosion resistant. The next problem is that workers have not used personal protective equipment (PPE) while working so they are vulnerable to respiratory diseases due to a polluted work environment. To overcome these problems, the PkM team designed problem solving with the following stages: (1) Problem mapping, (2) Problem solving, (3) Tool development, (4) Tool socialization (5) Partner Productivity Monitoring Evaluation (6) Safety and Health Socialization Work (K3). The use of a sifter with an electric motor is proven to reduce operating costs by up to 90%. In addition to operational costs that can be reduced, operating time per 1.3 tons of production also experiences an efficiency of up to 20%. The knowledge of partners regarding the operation of tools and the application of K3 at work has also increased. This is indicated by the application of the use of PPE including masks when working. Partners have also paid attention to the placement and use of work tools better by considering K3 factors.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan Thermoelectric Cooler (TEC) sebagai sistem pendingin udara masuk terhadap performa mesin sepeda motor 110 cc. Sistem TEC dipasang pada saluran intake manifold dan diuji menggunakan dynamometer test untuk membandingkan karakteristik mesin pada kondisi dengan dan tanpa pendinginan udara masuk. Parameter yang dianalisis meliputi daya, torsi, dan Air Fuel Ratio (AFR). Hasil pengujian menunjukkan bahwa pendinginan udara masuk menyebabkan penurunan nilai AFR sebesar sekitar 4,8%, yang mengindikasikan peningkatan densitas udara dan massa oksigen yang masuk ke ruang bakar. Perubahan tersebut berkontribusi pada peningkatan performa mesin, dengan daya maksimum mencapai 6,58 HP pada putaran 5600 rpm, atau meningkat sekitar 1,8 HP dibandingkan kondisi tanpa penggunaan TEC. Namun demikian, efektivitas pendinginan masih dibatasi oleh tingginya kecepatan aliran udara masuk, sehingga diperlukan pengembangan desain sistem pendingin yang lebih optimal pada penelitian selanjutnya.
