Abstract

Alluvial gold mining tailings in Logas consist of sand and mud, which are dominated by silica minerals and feldspar; the fine sand size fraction and the picking fraction are dominated by silica minerals, metals, and other high-hardness minerals. Tailings pose a new problem, namely sedimentation, which results in the silting of rivers, which causes flooding and damages community plantations. Tailings still have economic value, which can provide a source of income for the Tombang Tujuah Loge Producers Cooperative. This study formulates the idea of "stakeholders" so that all parties can participate in planning their business strategies. The Brainstorming Business Model Canvas method is able to explore potential ideas from stakeholders who are usually reluctant to convey ideas orally. The results of this study obtained the Business Model Canvas for strategy formulation regarding the development of a tailings utilization business.an bisnis pemanfaatan tailing

Abstract

Manintiang is a manual activity of separating gold from impurity particles (iron ore, silica, and ilmenite) through gravity, fluid pushing force, and friction force on the surface of the gold panning. Manual activities with an average weight of gold panning, water, and gold concentrate weighing 5–8 kg have the potential to cause musculoskeletal disorders (MSDs) in the short term and cumulative trauma disorders (CTDs) in the long term. This research aims to analyze the work posture of the "Manintiang" activity so that it can determine the potential for work injuries, identify unnatural work postures that cause discomfort at work, and identify work postures that have the potential to cause work accidents. The analysis methods used are REBA (Rapid Entire Body Assessment), RULA (Rapid Upper Limb Assessment), and OWAS (Ovako Working Analysis System) and use the Angle Meter 360 application version 1.9.3 for IOS. The results of this research is RULA = 7, REBA = 8, and OWAS = 2. Manintiang with a working position looking down and moving the gold panning back and forth is an unnatural working position, repetitive movements, and excessive muscle tension, which causes MSDs and CTDs.

Abstract

Production forecasting plays a crucial role in optimizing and managing the volume of output produced by an industry. Accurate forecasting provides essential information for production planning, enabling firms to respond to demand fluctuations and adjust operational policies in a timely manner. Crude palm oil (CPO) is one of the strategic commodities that requires reliable forecasting due to its importance in the food, energy, and downstream industries. This study employs two forecasting methods—moving average and ARIMA—using annual CPO production data from 1980 to 2024. The analysis shows that the five-year production forecast generated by the moving average method is 47.166.814 tons per year. Meanwhile, the ARIMA model predicts annual production of 42.277.393 tons, 44.500.436 tons, 44.705.101 tons, 44.714.519 tons, and 47.222.575 tons for the next five years. Accuracy evaluation using the Mean Absolute Percentage Error (MAPE) indicates that the moving average method performs well, with an error rate between 10% and 20%. In contrast, the ARIMA model demonstrates low accuracy, with a MAPE value exceeding 50%. These findings suggest that simpler methods, such as moving average, may outperform more complex models when forecasting annual CPO production. Peramalan produksi memiliki peran penting dalam mengoptimalkan dan mengelola jumlah output yang dihasilkan suatu industri. Peramalan yang akurat berfungsi sebagai dasar informasi bagi perencanaan produksi, memungkinkan perusahaan merespons perubahan permintaan serta menyesuaikan kebijakan operasional secara tepat waktu. Salah satu komoditas strategis yang membutuhkan peramalan adalah crude palm oil (CPO), mengingat perannya dalam industri pangan, energi, dan berbagai produk turunan lainnya. Penelitian ini menerapkan dua metode peramalan, yaitu moving average dan ARIMA, menggunakan data tahunan produksi CPO dari 1980 hingga 2024. Analisis menunjukkan bahwa proyeksi produksi CPO lima tahun ke depan menggunakan metode moving average adalah sebesar 47.166.814 ton per tahun. Sementara itu, metode ARIMA menghasilkan estimasi berturut-turut sebesar 42.277.393 ton, 44.500.436 ton, 44.705.101 ton, 44.714.519 ton, dan 47.222.575 ton per tahun. Evaluasi akurasi menggunakan Mean Absolute Percentage Error (MAPE) menunjukkan bahwa metode moving average berada pada kategori baik dengan nilai kesalahan 10–20%. Sebaliknya, metode ARIMA tergolong kurang akurat karena nilai MAPE yang dihasilkan melebihi 50%. Temuan ini menegaskan bahwa metode sederhana seperti moving average dapat memberikan performa yang lebih baik dibandingkan model kompleks untuk data produksi CPO tahunan.
