Abstract

Pengelasan merupakan proses penyambungan peralatan material benda logam yang digunakan dalm konstruksi bangunan maupun konstruksi peralatan mesin dimana pengunan elektroda las san berpengaruh pad material yg disambungkan. Dengan penerapan pada material Baja St 40 dan elektroda berdiameter Ø 2,6 mm maka dari hasil penelitian ini menunjukan analisa bahwa pnggunaan bahan pengelasan Elektroda Ø 26 mm memiliki kekuatan tarik yang lebih baik (96,7 kg/mm). Tegangan Nominal yang dihasilkan dari hail pengelasan menggunkan elektroda Ø 26 mm adalah sebesar 90,72 kg/mm², Regangan yang dihasilkan apabilai bandingkan dengan pengelasan dasar maka didapat hasil sebesar 0,75 kg/mm², Sedangkan reduksi yang dihasilkan sebesar 6,2 kg/mm². hal ini menunjukan bahwa pengunaan elektroda Ø 26 mm masih menjadi rekomendasi dalam penggunaannya

Abstract

Electric Motor or what is called as dynamo is a driving motor that converts electrical energy into kinetic energy. This energy change is carried out due to differences in the magnetic field in the coil so that when the coil is electrified, there will be a difference in the magnetic field which causes movement. Rustibus 2000 is a rust removal machine (scaling machine) that removes rust from the surface of ships. The role of the dynamo on the Rustibus is very continuous so maintenance must be scheduled and routine. Dynamo maintenance is carried out using a parallel work system and is carried out sequentially without paying attention to work priorities. Here, researchers apply the method of network planning with the CPM (critical path method) approach by looking for critical paths so that the electric motor reconditioning work which originally took 18 hours at a cost of Rp. 2,700,000 to 17.5 hours at a cost of Rp. 2,625,000.

Abstract

This study analyzes the reliability and performance of the water pump at Ben Mboy Campus, focusing on identifying issues and causes of failures, and developing improvement recommendations. An efficient water distribution system is crucial for supporting academic and operational activities at the campus. However, the pump used to transfer water from Rotiklot Dam frequently experiences failures, impacting water supply and operational costs. This research employs a descriptive quantitative method, collecting data through observations, interviews, and performance measurements to evaluate the frequency of pump failures in relation to operational time and workload. Regression analysis reveals a positive relationship between operational time and pump failure frequency, with recommendations to enhance maintenance scheduling and workload monitoring to reduce failures and improve system reliability. The research findings are expected to provide data-driven solutions for improving the water distribution system at Ben Mboy Campus and increasing its operational efficiency.
