Abstract

Agro-industrial work system, especially the sugar industry is a very complex work systems. In the approach to ergonomics, system components can be divided into human (workers), equipment and materials, physical environment and organizational environment. Each component interacts with the pattern of interrelation in the principle of autopoeisis (self-organizing system). Ergonomics analysis of the each component are needed in order to design or redesign the system, to ensure that work system can be sustainabe. This paper discusses some of the ergonomic aspects of work systems, among others, physical workload of manual harvesting, manual transporting of sugarcane and physical environmental conditions in the factory include vibration, temperature, noise, and lighting, as well as employee perceptions of work facing the system. Based on the comparison value IRHR (increase ratio of heart rate) for each job, the workload of manual harvesting categorized in moderate and severe categories (IRHR between 1.27 to 1.66) and manual transporting categorized in heavy and very heavy (IRHR between 1.43 to 1, 93). The physical condition of the factory there are some of the data beyond the allowed limit, for example, the highest temperature reached 37 0C, very low illumination of 7.5 lux, and the noise reached 93.2 dB. While the boiler operator workload is very heavy category (IRHR 1.67). From some of these results, it can be concluded that conditions are less ergonomic work systems, and requires some improvement in microergonomics aspects.

Abstract

Work safety has the main goal of protecting workers from risks associated with their work in the workshop area.  The purpose of this study is to identify, analyze, and control risks, as well as the dangers of work safety in one of the large workshops of PT United Tractors Jakarta Branch in the period June 2023 to August 2023. The results show that based on the results of the identification of 233 potential risks, it has been determined that ergonomic hazards emerged as a top priority, especially the risk of injury to fingers and hands. Initial risk assessment shows that almost all dangers are classified as moderate and unacceptable risk.  After the application of control obtained a relative risk value of 0.0386 and relative risk reduction of 96.14%.  The risk control approach shows that there are 10 preventive actions, 7 corrective actions, 8 detective actions, and 7 directive actions.  Recommendations for controlling ergonomic hazards are 3 preventive actions, 3 corrective actions, 3 detective actions, and 2 directive actions at the risk of finger injury. Keywords:  The Danger of Ergonomics, Relative Risk, Relative Risk Reduction, Risk Control Techniques.

Abstract

Mekanisasi pertanian telah terbukti nyata dapat meningkatkan produktivitas dan efisiensi usaha tani. Permasalahannya adalah Indonesia merupakan negara kepualauan terbesar di dunia dan memiliki beragam karakteristik tipe lahan pertanian. Hal ini menyebabkan penerapan dan perkembangan mekanisasi pertanian suatu daerah di Indonesia akan berbeda dengan daerah lainnya. Penelitian ini bertujuan melakukan analisis level mekanisasi dan menyusun strategi pengembangan mekanisasi pertanian di Kabupaten Bandung khususnya untuk tanaman padi sawah. Metode yang digunakan pada penelitian ini adalah metode survey dengan panduan kuisioner terstruktur. Level mekanisasi pertanian di hitung berdasarkan perbandingan antara ketersediaan tenaga mesin pertanian dalam satuan horse power (HP) dengan luas baku sawah dalam satuan hektar, sedangkan strategi pengembangan mekanisasi pertanian disusun berdasarkan analisis Strengths, Weaknesses, Opportunities, dan Threats (SWOT). Hasil analisis menunjukkan bahwa level mekanisasi pertanian kabupaten Bandung adalah 0,66 HP/Ha yang berasal dari aktivitas pengolahan tanah adalah 0,307 HP/Ha, pengairan 0,191 HP/Ha, penanaman 0,0017 HP/Ha, pemeliharaan tanaman 0,133 HP/Ha, dan pada aktivitas panen adalah 0,026 HP/Ha. Hasil analisis matrik internal eksternal diketahui bahwa strategi pengembangan mekanisasai pertanian di kabupaten Bandung adalah pertumbuhan melalui konsentrasi melalui integrasi horizontal.

Abstract

Diesel engines have long been the primary choice across various industrial sectors, including agricultural transport vehicles. However, energy efficiency and fuel consumption remain significant challenges. One approach to address these issues is the application of Ultra Fine Bubble (UFB) technology to diesel fuel, which aims to enhance physical fuel properties and improve combustion efficiency. This study was conducted to evaluate the effect of UFB treatment on B0 CN-51 and B40 fuels in relation to fuel quality and diesel engine performance. The fuel characterization tests showed that the calorific value of B0 CN-51 increased from 43.73 MJ/kg to 45.68 MJ/kg, and B40 from 42.46 MJ/kg to 42.94 MJ/kg. The cetane number also increased, accompanied by a reduction in sulfur content and lubricity. Performance testing using a chassis dynamometer indicated improvements in maximum power and torque. B0 CN-51 UFB produced 95.68 kW of power and 344.18 Nm of torque, while reducing specific fuel consumption (SFC) from 42.25 to 39.82 g/kWh. In addition, fuel consumption in ℓ/100 km decreased significantly, with an average reduction in efficiency of up to 4.85%. For B40, SFC decreased from 44.99 to 43.75 g/kWh, with an average consumption reduction of 1.73%. These results demonstrated that UFB can significantly improve diesel engine performance and fuel efficiency.
