Abstract

The main objective of a business feasibility study is to assess opportunities for a business project and whether the project is worth continuing or not. Results of calculation analysis on PT RA Beton Precast Concrete Wall Product Manufacturing Plant Design with an average production capacity of 128,772 pcs/year with two product designs (Type A-A and Type B-B). Based on the cash flow of the development investment plan, the new factory PT. RA Beton requires capital of Rp. 169.866.126.151.The calculations using the four methods, namely payback period (PP), produce results of 2 years and 4 months less than the economic life or maximum payback period, which is 10 years. Next, using the net present value (NPV) method, the results obtained are the NPV1 value > 0 from 75% interest amounting to Rp. 5,111,998,649, and the NPV2 value < 0 from 80% interest amounting to -Rp. 5,826,301,054. In calculating the Internal Rate of Return (IRR), results were obtained with a value of 94% greater than the applicable interest rate, namely 12%. Each method produces a different value; calculating the payback period concludes that the investment proposal can be accepted and declared feasible because it meets the criteria.

Abstract

This research aims to design a dynamic system model for the downstream copper processing industry. The secondary data obtained is data provided by the BKPM Strategic Investment Downstreaming Expert Team. Vensim software is used to simulate downstream development in the form of CLD and SFD from 2024 to 2045. The results of the value-added simulation resulted in an increase in the added value of copper cathode by 2.15 times, the added value of cathode slab by 1.62 times, the added value of copper billet by 1.65 times, the added value of copper bar &rods by 1.08 times, the added value of copper tube by 1.02 times, the added value of copper strip by 1.39 times, and the added value of copper wire by 1.58 times. After a sensitivity analysis of the selling price at CAGR and an increase in energy costs by 20%, there was a change in the average value-added margin, so that the increase in added value changed which resulted in an added value of copper cathode of 1.9 times, added value of cathode slab of 1.47 times, added value of copper billet of 1.49 times, added value of copper bar &rods of 1.26 times, added value of copper tube of 0.93 times, added value of copper strip of 0.98 times, and added value of copper wire of 1.44 times.

Abstract

This research aims to analyze the distribution cost structure and transportation requirements for CPO-FAME-Biodiesel to meet B40 quota implementation in Java Island using a dynamic system approach. This study uses dynamic system simulation with Vensim software to model CPO-FAME-Biodiesel distribution from Sumatra and Kalimantan to Java Island, utilizing data from Ministry of Energy and Mineral Resources and GAPKI with 2025 projections. The simulation reveals that meeting the B40 quota in Java Island requires substantial infrastructure investment with total transportation costs exceeding IDR 1.3 trillion, highlighting the massive scale and logistical complexity of national biodiesel implementation. Analysis identifies fleet tariff, shipping frequency, fleet capacity, raw material prices, and conversion ratios as the primary cost drivers affecting distribution efficiency. Cost optimization can be achieved through strategic shipping frequency management, capacity optimization, efficient fleet fuel management, and implementation of centralized production systems with hub-and-spoke distribution networks. This research contributes essential strategic insights for policymakers in developing cost-effective transportation frameworks and infrastructure planning for Indonesia's national biodiesel policy implementation.
