ANALISIS PRODUKTIVITAS EXCAVATOR SANY SY215C DAN BIAYA OPERASIONAL PADA PEKERJAAN GALIAN CETAK SAWAH RAKYAT (CSR) KABUPATEN TAPIN, DESA SUNGAI SALAI

Abstract

The Cetak Sawah Rakyat (CSR) Program, precisely in Sungai Salai Village, Tapin Regency, South Kalimantan Province, is implemented to expand agricultural land in support of national food security toward rice self-sufficiency. In the 253-hectare CSR project area, peatland excavation work uses the SANY SY215C Excavator; however, the actual productivity and operational cost of the equipment have not been precisely determined. This study aims to determine the actual productivity of the SANY SY215C Excavator, analyze its hourly operational cost — comprising Ownership cost, operating cost, and maintenance cost — and identify the technical, operational, and environmental factors that influence it. The research employed a time study method on 300 Excavator working cycles over six days of observation, with operational cost calculations based on the Regulation of the Minister of Public Works and Housing (PUPR) No. 08/PRT/M/2023. The results show an average cycle time of 22.83 seconds, yielding an actual productivity of 133.89 m³/hour or 937.23 m³/day, with a total operational cost of IDR 866,031/hour (operating cost of IDR 590,768/hour and Ownership cost of IDR 275,263/hour), equivalent to IDR 6,468/m³ of excavation work. With seven Excavator units in operation, the total projected operational cost exceeds IDR 1.36 billion. Technical, operational, and environmental factors were found to significantly affect productivity and cost efficiency. These findings are expected to serve as a practical reference for government agencies, contractors, and project planners in preparing the Budget Plan (RAB) and improving the operational efficiency of heavy equipment in the Cetak Sawah Rakyat Program.
