EVALUASI STANDAR OPERASIONAL PROSEDUR PENGUJIAN KEMAMPUAN PENGEREMAN MOBIL BARANG SISTEM REM LSPV DI UPTD PKB KABUPATEN SRAGEN (STUDI KASUS MOBIL GRAN MAX)

Load Sensing Proportioning Valve (LSPV) is a hydraulic valve used in automotive braking systems to regulate the rear brake pressure based on the vehicle's load. At UPTD PKB Kabupaten Sragen, the braking capability testing is conducted using the same Standard Operational Procedure (SOP) for both vehicles with and without LSPV brake systems. Therefore, it is necessary to have an SOP that ensures the quality of testing, particularly for vehicles equipped with LSPV brake systems, and provides guidelines for the testing procedures.
The research method used is experimental-based, where a test of loading capacity from 0 kg to 100 kg is conducted. The testing is performed on axle 1 and axle 2. Data is collected through 5 repetitions for each variation of loading capacity. Based on the data obtained, the appropriate standard load used to achieve optimal braking capability in the LSPV brake system is 63 kg. At this loading capacity, the braking capability reaches its highest value, and the valve in the LSPV brake system is fully open, and these results will be included in the SOP for testing the LSPV brake system.
