Abstract

Occupational accidents continue to occur in industrial environments, indicating gaps in workplace safety management and preventive controls. This study applies the Systematic Cause Analysis Technique (SCAT) to identify the root causes of work accidents and to develop safety standard operating procedures (SOPs) at PT Hok Tong.This research aims to analyze the application of the Systematic Cause Analysis Technique (SCAT) method in preparing work safety Standard Operating Procedures (SOP) at PT. Hok Tong Jambi, a natural rubber processing company that faces significant safety risks for its workers. Data was obtained through field observations, in-depth interviews with HSE staff and production workers, as well as reviewing work accident documents. Analysis using the SCAT model identifies the root causes of work accidents, including negligence, non-compliance with SOPs, and lack of adequate use of Personal Protective Equipment (PPE). This research found that factors such as lack of safety awareness, less than optimal supervision, and inconsistent implementation of SOPs were the main causes of work accidents in this company. Based on the results of the SCAT analysis, work safety SOPs were prepared as an effort to prevent and control work accidents, with the hope of increasing worker awareness and safe behavior. This research suggests strengthening supervision and more intensive safety training to minimize the risk of workplace accidents.

Abstract

Penelitian ini bertujuan untuk merancang dan membangun prototipe pembangkit listrik alternatif thermoelectric generator (TEG) sebagai media pembelajaran energi terbarukan yang efisien. Metode penelitian yang digunakan adalah ADDIE yang meliputi tahapan Analysis, Design, Development, Implementation, dan Evaluation. Komponen utama prototipe terdiri dari tungku briket batok kelapa sebagai sumber panas, empat buah modul Peltier SP 1848-27145 SA yang disusun seri, sistem pendingin air, serta boost converter XL6009 untuk menstabilkan tegangan keluaran. Hasil pengujian menunjukkan bahwa performa terbaik dicapai saat menggunakan sistem pendingin air radiator, dengan suhu sisi panas mencapai 150,5°C dan sisi dingin 34,9°C. Kondisi ini menghasilkan beda temperatur (ΔT) sebesar 115,6°C yang mampu membangkitkan tegangan hingga 3,44 Volt sebelum masuk ke boost converter. Melalui penggunaan boost converter, tegangan berhasil ditingkatkan menjadi 12,89 Volt untuk menyuplai beban lampu DC 10 Watt. Arus puncak yang dihasilkan tercatat sebesar 0,588 Ampere dengan daya listrik maksimum mencapai 7,58 Watt. Penelitian ini membuktikan bahwa prototipe mampu mengonversi energi panas menjadi listrik secara efektif untuk aplikasi skala kecil dan layak digunakan sebagai sarana edukasi teknologi energi baru terbarukan.

Abstract

The global transition toward renewable energy is increasingly urgent to mitigate climate change and reduce dependence on fossil fuels; however, it also introduces economic risks such as greenflation, driven by rising demand for green commodities. In Indonesia, renewable energy development has become a national priority, with Jambi Province identified as a strategic region due to its significant micro-hydropower (PLTMH) potential. This study aims to predict PLTMH potential as a means of supporting energy transition planning and preventing greenflation through data-driven policy decisions. The research employs a Bayesian Structural Time Series (BSTS) approach using JASP software, integrating Kalman Filter, spike-and-slab regression, and Bayesian Model Averaging. Time series data from 2008–2024 were analyzed with 2,000 MCMC draws and a 1% burn-in to ensure estimation stability. The results demonstrate a strong upward trend in PLTMH capacity, with high model accuracy indicated by an R² value of 0.991, low residual standard deviation, and acceptable prediction uncertainty. Forecasts suggest continued growth in PLTMH capacity over the next two decades before reaching a steady state. The study concludes that BSTS is a robust and reliable method for predicting renewable energy potential and supporting counterfactual policy analysis. This research contributes empirically to applied Bayesian time series modeling and practically to renewable energy policy planning, offering evidence-based insights to enhance energy security and mitigate greenflation risks.

Abstract

The growing problem of microplastic contamination has prompted the need for safer and more environmentally friendly food packaging alternatives. An edible film made from gelatin with the addition of chitosan, sorbitol, TiO?, and oleogel has been developed to replace conventional plastic, which is difficult to decompose. This study aims to determine the physical properties of gelatin with oleogel-based edible film in terms of the physical and mechanical properties of edible films. Treatment: the use of different oleogel (0%, 3%, 6% and 9%) with 4 replications. The method used was an experimental method using a Completely Randomized Design (CRD). The observed variables were Water Vapor Permeability (WVP), solubility, thickness and transparency. The parameters observed included swelling, moisture content, color intensity (L*, a*, b*), tensile strength, elongation at break. Data were analyzed using Analysis of Variance (ANOVA). The results of the study using oleogel with different percentage show highly significant differences (p < 0.01) on wvp, solubility, thickness, transparency, swelling, moisture content, color, breaking strength and tensile strength, but did not show significant differences (p > 0.05) on a* value. The results showed that the addition of oleogel reduced moisture content, swelling, L* values, solubility, wvp and breaking strength but increased a* value, b* values, tensile strength, thickness and transparency. Based on these results, the use of oleogel in edible films can enhance physical and mechanical properties of edible films, thereby potentially serving as an environmentally friendly alternative for food packaging
