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.

Abstract

Waste such as used diapers remains a persistent environmental challenge that requires effective waste management solutions. This study aims to evaluate the performance and efficiency of an incinerator using diapers as the primary waste material. An incinerator can reduce waste volume and mass by converting it into ash. This experimental study using used oil and cooking oil as fuels for a steam-pressurized burner system. Variations in two-tiered air intakes are also used as a measure of evaluation of air velocity, which are 6 m/s, 8 m/s, and 10 m/s. The results demonstrates that for used oil fuel, average combustion temperatures of 376°C, 405°C, and 452°C were obtained at 6, 8, and 10 m/s, with combustion times of 97, 75, and 56 min, respectively. Residual ash masses were 1.01, 0.80, and 0.60 kg. For used cooking oil fuel, average temperatures reached 325°C, 354°C, and 387°C, with combustion times of 120, 107, and 86 min, respectively. Residual ash masses were 1.20, 1.08, and 0.85 kg. The results show that increasing air velocity significantly improved combustion temperature and reduced burning time for both fuels, while its effect on ash residue was less pronounced. Used oil produced higher combustion temperatures and faster waste reduction, whereas the highest thermal efficiency of 70% was achieved using used cooking oil at an air velocity of 10 m/s.

Abstract

Peningkatan jumlah kendaraan bermotor berbanding lurus dengan meningkatnya limbah oli bekas yang berpotensi mencemari lingkungan jika tidak dikelola dengan baik. Oleh karena itu, diperlukan upaya pemanfaatan limbah oli bekas sebagai sumber energi alternatif yang bernilai guna, salah satunya sebagai bahan bakar kompor. Penelitian ini bertujuan untuk mengidentifikasi karakteristik kimia oli bekas serta menentukan rasio udara-bahan bakar (air–fuel ratio) yang optimal guna menghasilkan proses pembakaran yang efisien. Metode yang digunakan meliputi analisis komposisi kimia menggunakan Gas Chromatography-Mass Spectrometry (GC-MS) untuk menentukan senyawa dominan dalam oli bekas, serta perhitungan stoikiometri untuk memperoleh rasio udara dan bahan bakar ideal. Selanjutnya dilakukan pengujian eksperimental dengan variasi kecepatan aliran udara masuk sebesar 1,16; 1,66; 2,16; 2,66; dan 3,16 m/s. Hasil analisis GC-MS menunjukkan bahwa senyawa dominan dalam oli bekas adalah dekosana (C₂₀H₄₂), sehingga diperoleh rasio stoikiometri udara-bahan bakar sebesar 14,8:1. Pengujian pembakaran menunjukkan bahwa kondisi optimal terjadi pada kecepatan udara masuk 2,16 m/s, dengan suhu nyala api mencapai 876,8°C dan suhu tungku 535,2°C, serta waktu pembakaran 1627 detik. Suhu tertinggi diperoleh pada kecepatan udara 3,16 m/s dengan suhu api 1103,3°C dan suhu tungku 688,5°C, namun dengan waktu pembakaran lebih singkat yaitu 1229 detik. Sebaliknya, suhu terendah terjadi pada kecepatan udara 1,16 m/s dengan suhu api 755,7°C dan suhu tungku 290,4°C, serta waktu pembakaran terlama yaitu 2224 detik. Berdasarkan hasil tersebut, dapat disimpulkan bahwa peningkatan kecepatan aliran udara berpengaruh signifikan terhadap kenaikan suhu pembakaran dan percepatan proses pembakaran, meskipun kondisi optimal dicapai pada kombinasi tertentu yang menghasilkan efisiensi termal terbaik.
