Abstract

The Employee Leave Request procedure at the Personnel Department, Spun Yarns Division, PT Indorama Synthetics Tbk, is still manual and paper-based, causing long waiting times and low efficiency. This study maps the current (As Is) process, identifies the most dominant Non-Value Added (NVA) components, and formulates and analyzes a To Be proposal through Business Process Reengineering (BPR) with its gap analysis. This applied, quantitative-descriptive study uses flowcharts and time observation to classify Value-Added (VA) and NVA activities. Results show the As Is process has 9 steps with a total cycle time of 194.00 minutes, of which 153.2 minutes (79.0%) are NVA, mainly waiting time for HOD/Supervisor approval (72.5 minutes) and Remuneration Staff processing (49.8 minutes). The To Be design reduces actors from five to four, eliminates 4 steps, digitizes 2 steps, and automates 2 steps. The gap analysis shows the cycle time cut to 45.80 minutes, a 76.39% efficiency gain.

Abstract

Indonesia's mandatory bioethanol-blending program faces a substantial domestic supply gap, with demand projected to grow from 478,358 KL in 2026 to 1,170,453 KL by 2040. This study examines the investment feasibility of establishing a 100,000 KL/year sugarcane-molasses bioethanol plant in Bojonegoro and its sensitivity to changes in raw-material and selling prices. A quantitative descriptive approach was applied using secondary data from BPS, ESDM, P3GI, and scientific literature. Financial feasibility was assessed through NPV, IRR, Payback Period, and BEP. The base-case scenario yields an IRR of 14.13% (MARR 10%), NPV of IDR 322.45 billion, and a 6-year payback period. Under a sensitivity scenario combining higher molasses prices and lower selling prices, IRR declines to 13% yet remains feasible, with NPV of IDR 70.98 billion and a BEP of 50,000 KL/year. The project is therefore feasible and reasonably resilient to market price fluctuations.
