"Penelitian ini bertujuan untuk mengembangkan model strategi penentuan lokasi stockpile sentral batubara di Binuang, Kalimantan Selatan. Penelitian ini menggunakan metode Center of Gravity (COG) dan Factor Rating Analysis (FRA) untuk mencapai lokasi optimal yang meminimalkan biaya transportasi dan memaksimalkan efisiensi logistik. Data dari izin usaha pertambangan dan terminal khusus dikumpulkan, dan perhitungan COG dilakukan untuk mengidentifikasi pusat geografis untuk aktivitas pertambangan dan pengapalan. Selain itu, kuisioner digunakan untuk mengidentifikasi faktor-faktor yang paling berpengaruh dalam penentuan lokasi stockpile. Lima faktor kunci yang diidentifikasi adalah: jumlah populasi terdampak, luas lahan potensial, jarak ke COG pertambangan, jarak ke COG terminal/pelabuhan, dan perizinan lahan. Factor Rating Analysis kemudian diterapkan pada tiga kecamatan potensial: Anjir Pasar, Kapuas Murung, dan Candi Laras Utara. Anjir Pasar muncul sebagai lokasi yang paling sesuai berdasarkan skor tertimbang tertinggi. Penelitian ini diakhiri dengan rekomendasi untuk mengimplementasikan strategi yang dipilih untuk memastikan operasi stockpile batubara yang efisien dan berkelanjutan.

This research aims to develop a strategic model for determining the location of a central coal stockpile in Binuang, South Kalimantan. The study utilizes the Center of Gravity (COG) method and Factor Rating Analysis (FRA) to achieve an optimal location that minimizes transportation costs and maximizes logistic efficiency. Data from mining permits and special terminals were collected, and COG calculations were performed to identify the geographical center for mining and shipping activities. Additionally, a questionnaire was used to identify the most influential factors in determining the stockpile location. The five key factors identified were: affected population, potential land area, distance to COG mining, distance to COG terminal/port, and land permits. Factor Rating Analysis was then applied to three potential sub-districts: Anjir Pasar, Kapuas Murung, and Candi Laras Utara. Anjir Pasar emerged as the most suitable location based on the highest weighted score. The study concludes with recommendations for implementing the chosen strategy to ensure efficient and sustainable coal stockpile operations."

"Peningkatan konsumsi perangkat elektronik di Indonesia mendorong timbulan limbah elektronik (e-waste), khususnya Waste Printed Circuit Board (WPCB), yang mengandung logam-logam berharga seperti emas, perak, tembaga, dan platinum. Penelitian ini bertujuan untuk menganalisis potensi ekonomi dari daur ulang WPCB di Pulau Sumatera serta memberikan rekomendasi lokasi fasilitas pengolahannya. Metodologi yang digunakan meliputi pengumpulan data timbulan WPCB per provinsi (2025–2040), estimasi kandungan logam berharga berdasarkan literatur (UNEP, Umicore), dan analisis nilai pasar logam secara aktual. Perhitungan potensi pendapatan dilakukan melalui pendekatan excel-based valuation. Selanjutnya, penentuan lokasi fasilitas dilakukan menggunakan pendekatan Multi-Criteria Decision Making (MCDM) dengan Factor Rating Method, yang mempertimbangkan kriteria seperti luas lahan, legalitas, aksesibilitas, kapasitas pengolahan, dan jarak dari wilayah pelayanan. Hasil penelitian menunjukkan bahwa potensi ekonomi daur ulang WPCB di Sumatera mencapai nilai yang signifikan dan layak secara investasi. Lokasi yang optimal untuk fasilitas pengolahan diperoleh dari hasil pembobotan berdasarkan kriteria teknis dan spasial. Penelitian ini merekomendasikan pembangunan fasilitas pengolahan terpusat di provinsi dengan timbulan terbesar dan konektivitas terbaik untuk menunjang efisiensi logistik dan nilai ekonomi maksimal.

The increasing consumption of electronic devices in Indonesia has driven the generation of electronic waste (e-waste), especially Waste Printed Circuit Board (WPCB), which contains precious metals such as gold, silver, copper, and platinum. This study aims to analyze the economic potential of WPCB recycling in Sumatra Island and provide recommendations for the location of processing facilities. The methodology used includes collecting WPCB generation data per province (2025–2040), estimating precious metal content based on literature (UNEP, Umicore), and analyzing the actual metal market value. The calculation of potential income is carried out using an excel-based valuation approach. Furthermore, the determination of the location of the facility is carried out using the Multi-Criteria Decision Making (MCDM) approach with the Factor Rating Method, which considers criteria such as land area, legality, accessibility, processing capacity, and distance from the service area. The results of the study indicate that the economic potential of WPCB recycling in Sumatra reaches a significant value and is feasible for investment. The optimal location for the processing facility is obtained from the weighting results based on technical and spatial criteria. This study recommends the construction of a centralized processing facility in the province with the largest generation and the best connectivity to support logistics efficiency and maximum economic value."
