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 investigates carbon footprint optimisation strategies in the nickel-based industrial development at Indonesia Morowali Industrial Park (IMIP), focusing on sustainable supply chain management practices. The study employs a mixed-method approach, combining quantitative analysis of carbon emissions data with qualitative assessment of supply chain processes. Through comprehensive data collection from 2019-2024 and analysis of multiple operational parameters, the research identified key optimisation opportunities across mining operations, processing plants, and transportation networks. Results indicate that implementing targeted optimisation strategies across the supply chain could reduce carbon emissions by 15-20% while maintaining production efficiency. Specific interventions, including waste heat recovery systems, fleet electrification, and smart logistics integration, demonstrated significant impact with potential annual savings of 87,500 tCO2e and $11.2 million in operational costs. The study also revealed that integrating sustainable practices led to an 18% improvement in production efficiency and a 12% enhancement in resource recovery rates. The findings contribute to the growing knowledge of sustainable industrial development in the mining and metallurgical sectors, offering practical insights for similar industrial parks globally. This research provides valuable frameworks for balancing environmental sustainability with industrial growth in emerging economies.

Abstract

The business process of the J20 production department is currently experiencing obstacles in terms of information delivery, production report, maintenance report, and problem information that causes decision making is often irrelevant. This is due to the use of paper media with a long bureaucratic flow so that the cycle time becomes inefficient. This study used business process reengineering, modeling business process in business process modeling notation (BPMN), and supporting research problem analysis used fishbone diagram. The result showed changes in a process flow, job desk, unit elimination, and proposed design of information systems in the form of application software as a solution to the problems studied, so that it is expected to obtain process time efficiency of 65.1% and cycle time of 99.2% of the previous total time. Proses bisnis departemen produksi J20 saat ini mengalami hambatan dalam hal penyampaian informasi, laporan hasil produksi, laporan maintenance, serta informasi problem, yang menyebabkan pengambilan keputusan sering kali terjadi bias. Hal ini di sebabkan oleh penggunaan media kertas dengan alur birokrasi yang panjang sehingga waktu siklus menjadi tidak efisien. Pada penelitian ini digunakan metode Business Process Reengineering, dengan memodelkan bisnis proses dalam Business Process Modelling Notation (BPMN), serta pendukung analisa masalah penelitian digunakan diagram tulang ikan. Hasil penelitian menunjukan adanya perubahan alur proses, jobdesk, eliminasi unit, serta usulan perancangan sistem informasi berupa software aplikasi sebagai solusi dari permasalahan yang diteliti, sehingga diharapkan dapat diperoleh efisiensi waktu proses sebesar 65,1% dan waktu siklus sebesar 99,2% dari total waktu sebelumnya.

Abstract

Indonesia's dependence on imported caustic soda (NaOH) poses a significant strategic vulnerability, particularly for the textile, paper, alumina refining, and water-treatment industries. This study presents a comprehensive feasibility analysis for establishing a 500,000-ton-per-year NaOH plant in Gresik, East Java, under the Indonesian government's downstream industry (hilirisasi) program. The chlor-alkali membrane electrolysis process was selected as the production method owing to its superior energy efficiency and product purity. Mass and energy balances were rigorously calculated, establishing brine feed requirements of approximately 1,500,000 tons per year and a specific energy consumption of 2,800 kWh per ton of NaOH. Technical process design, equipment sizing, and utility requirements are presented alongside a detailed economic evaluation. Capital expenditure (CAPEX) is estimated at USD 680 million, with an annual operating expenditure (OPEX) of USD 290 million. Financial analysis yields a net present value (NPV) of USD 412 million, an internal rate of return (IRR) of 18.7%, a payback period of 5.4 years, and a break-even point at 62% plant utilization. The Gresik location provides strategic advantages including proximity to raw material sources, existing industrial infrastructure, and deep-water port access. Environmental impact and sustainability assessments confirm compliance with Indonesian environmental standards. This study concludes that the proposed NaOH plant is technically viable and financially attractive, supporting national self-sufficiency in basic chemicals.

Abstract

Warehouse layout optimization in the food manufacturing industry remains a critical yet underexplored challenge, particularly for multi-product operations with heterogeneous storage requirements and high-throughput demands. Previous studies have predominantly focused on single-criterion evaluations or general industrial settings, leaving a notable gap in the application of comprehensive, multi-criteria Systematic Layout Planning (SLP) frameworks to finished goods warehouses in the food sector. This study addresses that gap by designing an optimal product layout for a finished goods warehouse in an instant noodle manufacturing facility with an annual production capacity of 20 million units. The SLP method was implemented through six structured phases: activity relationship analysis, space requirements determination, relationship and space diagram construction, alternative layout generation, and weighted multi-criteria quantitative evaluation. Three layout alternatives were systematically assessed using criteria encompassing material handling efficiency, space utilization, operational flexibility, and implementation cost. The U-shaped layout emerged as the optimal design, attaining the highest weighted evaluation score and demonstrating substantial reductions in material handling distance and operational cost relative to conventional linear configurations. The findings confirm that the SLP method provides a robust and replicable framework for warehouse layout optimization in multi-product food manufacturing environments, offering actionable guidance for facility planners confronting analogous operational constraints.
