Abstract

Tombang Tujuah Loge ASGM Cooperative operates in the field of Artisanal small-scale gold mining (ASGM) and produces fine gold. The Exploitation and Fine Gold Refinery Process involves direct interaction of workers with equipment and the environment in a production situation that has quite a high safety risk. The research aims to identify the type or source of danger, determine the high-risk value, and take appropriate risk control measures. The method used is Failure Mode and Effect Analysis (FMEA) to identify failures in facilities, systems, or equipment that have an impact on work accidents. The research results show that the highest risk is the danger of landslides at mining sites (RPN: 120) and exposure to dangerous chemicals in Fine Gold Refinery Process activities (RPN: 112). The results of data processing using Failure Mode and Effect Analysis (FMEA) provide recommendations, namely (1) Landslide Early Detection System; (2) Incinerator; and (3) Use of Personal Protective Equipment.

Abstract

The initiative to process coconut shell charcoal emerged as some farmers began selling coconuts as copra, leaving the shells available for charcoal production. However, further processing into coconut shell charcoal briquettes—which offer higher economic value—remains limited. Twelfth-grade high school students (aged 17–19) are in a transitional phase toward employment or higher education, requiring the provision of practical skills. A skills training program on coconut charcoal briquette production was held in January 2025 at SMA Karya Pengalihan Keritang, involving 40 students. The training included hands-on briquette making and business economic analysis. This activity aimed to provide entrepreneurial experience and enhance job readiness. The expected impact is that participants will recognize the economic potential of briquette production as a viable business opportunity, given the high profit margins between production costs and market prices.

Abstract

The tradition in this study refers to customs, beliefs, habits, and other things inherited in descent. These inherited customs encompass a variety of cultural values that include customs, social systems, knowledge systems, languages, arts, belief systems and so on. The aim of this research is to find out the traditional shape of the barak boy pancar that exists in the area of Kuantan Rantau and the cultural values that exist in it. This research uses a qualitative approach with descriptive methods. Data collection is done through observations, interviews, documentation and literature studies. The tradition of bararak son pancar is one of the forms of tradition that exists in Malay society which contains very high cultural values. Cultural values become guidelines of behavior for a society of one generation to the next. This process makes cultural values continue to be preserved and inherited by society downward.

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

Grate the coconut is one of kitchen activity which faces by housewife in daily life. A coconut grater product which is distibuted in market, one of them is manual crank system. Housewife complain that they feel painfull in their body, especially at hand. Waist and back after using available old tool. This research is purposed to improve the design of coconut grater with crank system by ergonomic function deployment (EFD) approach, also to known mosculuskletal reducing of housewife as user and show differention time of grater after redesign done. Research was conducted in RT. 001 RW.005 Tembilahan, Indragiri Hilir District. Research model used treatment by subject design with total sample is 12 housewife which is calculation by Colton Formula. Improvement new coconut grater design with crank system which EFD got by creat the matrix house of ergonomic (HOE) and determination of anthropometry data. Mosculuskletal complain on housewife is measured by making the Nordic Body Map (NBM) Questionnaire work sheet. Time of grated the coconut got by testing coconut grater by crank system on before and after using. Research finding after redesign of coconut grater of crank system shown that design of coconut grater of crank system with EFD and base on ergonomic acpects (effective, confort, savety, healthy and efficient. Mosculuskletal complaint that happend on housewife decrease about 0,285 or 17,39%. Time of grate is also faster around 5 minutes or has imporove 30,1%.

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.
