Abstract

Diesel engine adalah salah satu jenis engine yang sangat sesuai digunakan pada transportasi alat berat dikarenakan memiliki nilai performansi (torsi dan daya) yang besar. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh variasi putaran engine terhadap nilai performansi Engine Liebherr D9512. Pengambilan data dilakukan pada saat engine dioperasikan menggunakan alat uji Power Test Dynamometer 35X05. Hasil dari pengujian yang dilakukan didapatkan bahwa variasi putaran engine akan berpengaruh terhadap nilai performansi. Pada putaran engine 1100 RPM nilai torsi sebesar 2204 N.m pada hasil dynotest remanufacture dan 2211 N.m pada hasil dynotest factory. Pada putaran engine 1500 RPM nilai torsi 3489 N.m dan 3496 N.m pada hasil dynotest factory. Pada putaran engine 2000 RPM nilai torsi 2754 N.m dan 2883 N.m pada hasil dynotest factory. Di sisi lain variasi putaran engine juga berpengaruh terhadap nilai daya engine. Data pengujian pada putaran engine 1100 RPM nilai daya sebesar 253 KW pada hasil dynotest remanufacture dan 268 KW pada hasil dynotest factory. Pada putaran engine 1500 RPM nilai daya 520 KW dan 523 KW pada hasil dynotest factory. Pada putaran engine 2000 RPM nilai daya dynotest remanufacture dan dynotest factory adalah sama yaitu sebesar 565 KW

Abstract

The issue of equitable development and demographic conditions is a key issue facing the west Kutai (Kubar) Regency government, impacting job availability and improving the knowledge and skills of human resources (HR). The goal of the Community Service (PKM) operator training program is to prepare qualified Wheel Excavator Operator Trainees for the community and to help maximize the potential of their human resources in their respective fields through training. The implementation method for the Junior Level 2 Wheel Excavator Operator Training includes preparation stages, including determining the training schedule, socialization, training, and certification. The training took place at the Simpang Raya Village Meeting Hall, Barong Tongkok District, West Kutai (Kubar) Regency, East Kalimantan Province. The training provided participants with basic knowledge of safety, operation, and maintenance procedures (P2H). This significantly assisted them in improving their skills, particularly for future professional certification. It also positively impacted perceptions and increased participant enthusiasm for the training.
