Abstract

The purpose of holding this community service program is to provide training to subject teachers at Vocational High Schools (SMK) on the integration of numeracy skills in subjects taught at SMK. The method used to run this program is the direct talk show method between the resource persons and the participants of the training program. The results obtained from this activity are (1) the positive response from all participants to the program we hold; (2) response to the attractiveness of the presentation of material 84.44% in the very interesting category, 11.11% in the interesting category, and 4.45%; The response to benefits was 95% in the very useful category and 5% in the beneficial category. Another result that we obtained from this activity is an increase in knowledge about the integration of numeracy skills into several subjects in Vocational High Schools. This proves that teachers as the main figures in the world of education can be directly involved in helping the government in improving numeracy skills. Teachers can provide simple examples of students' life problems, so that students can directly apply their knowledge of numeracy. The habituation of students in solving problems about numeracy is also a driver to improve numeracy skills in the students themselves.

Abstract

Occupational Safety and Health (OSH) plays a critical role in maintaining safe and sustainable production, particularly in small-scale agro-industrial operations such as coffee processing. This study applies the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) framework to evaluate workplace hazards at Kopi Lanange Jagad, a micro-scale coffee producer in Malang Regency, Indonesia. Field observations and structured interviews were conducted to identify potential hazards across four production stages roasting, grinding, sieving, and packaging. Quantitative measurements were also taken, including ambient temperature, noise level, and airborne dust concentration, to provide empirical data for risk evaluation. The findings identified a total of 12 hazards, classified into three risk categories: high (25%), moderate (50%), and low (25%). The roasting process exhibited the highest risk score (R = 18.4), with average workplace temperatures reaching 85°C–120°C, significantly exceeding the national occupational limit of 30°C for moderate workloads (Permenaker No. 5/2018). The grinding stage also presented considerable hazards, with airborne dust concentrations averaging 2.4 mg/m³, approaching the Ministry of Manpower’s threshold limit value (TLV) of 3 mg/m³. Manual packaging was associated with ergonomic strain, where workers lifted 15–20 kg sacks repeatedly, leading to potential musculoskeletal disorders. Risk evaluation revealed that existing control measures such as natural ventilation and sporadic use of personal protective equipment (PPE) were insufficient to ensure worker safety. To reduce these hazards, the study recommends implementing engineering controls such as local exhaust ventilation and machine insulation, combined with administrative measures including job rotation, scheduled rest breaks, and regular safety training. Ensuring consistent PPE use especially heat-resistant gloves, dust masks, and ear protection can further mitigate residual risks. Overall, the application of the HIRARC framework at Kopi Lanange Jagad demonstrates its effectiveness as a low-cost and practical tool for identifying, prioritizing, and managing occupational hazards in small-scale coffee industries. Implementation of the proposed control strategies is projected to reduce total workplace risk by 35–40%, improving both worker well-being and operational productivity.

Abstract

Confined space activities in fertilizer production present significant risks, including toxic gas exposure, oxygen deficiency, fire and explosion hazards, and physical or ergonomic challenges. This study applies the Job Safety Analysis method to systematically identify hazards, assess risks, and establish effective control measures during the repair and maintenance of the FRP Pond 22000 Kl at the fertilizer division on seasoning industry. The methodology consisted of six structured stages: job selection, task breakdown, hazard identification, risk control, verification, and monitoring. Hazard identification was carried out through field observation, consultation with Health, Safety, and Environment officers, and adherence to national regulatory standards. Results revealed that atmospheric testing prior to entry was essential, with oxygen levels recorded at 20.8% and toxic gases, within safe limits. The JSA identified potential risks at each task stage and applied control measures following the hierarchy of controls, including engineering controls ventilation, and gas detection. While administrative measures section permit towork system, time restrictions, and health certificates. On energy isolation is installation Lock Out Tag Out. The essential is mandatory of personal protection equipment. Collaborative inspections by contractors, supervisors, and Health, Safety, and Environment staff reinforced compliance and improved communication. The study concludes that job safety analysis is not only a compliance requirement but also a practical framework for hazard anticipation, safety culture reinforcement, and operational continuity. It is recommended that future practice integrates digital job safety analysis systems, real-time monitoring, and enhanced training to strengthen confined space safety in fertilizer production and other high-risk industries.
