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

Diesel engines are known as high efficiency engines and are used in public transportation and agricultural sector. The exhaust gas produced by diesel engines is dangerous for human health. Ultra Fine Bubble (UFB) technology which is currently being developed is an emission reduction alternative that can enrich oxygen in fuel and has the potential to reduce emissions. This research was carried out to apply UFB technology to a variety of fuels and compare the emission results. This research method is data collection based on experimental tests. The types of fuel used in this research are biodiesel and biodiesel-diesel mixture. The research procedure starts from instrument preparation, fuel inflation which produces UFB fuel, fuel characteristics, instrument performance testing and data processing. The characteristic testing method follows the American Standard Testing and Materials (ASTM) and performance testing follows the ISO/IEC 17025:2017 standard. The research results show that fuel treated with ultra-fine bubbles can reduce exhaust emissions compared to fuel without UFB. CO content decreased by 608 parts per million (ppm) in the biodiesel-diesel blend and 306 ppm in biodiesel with UFB. The exhaust gas temperature becomes stable when the fuel contains bubbles and reduces NO and NOx content in emissions. Keywords: Biodiesel, Diesel engine, Fuel, Ultra fine bubble

Abstract

This study aims to test the loading on the catcher components of the E-Bhar machine, as well as estimate the bruise index (BI) and free fatty acids (FFA) in the Fresh Fruit Bunches (FFB) caught. The loading test was conducted by dropping artificial FFB weighing 35 kg from a height of 1 m for 16 trials to analyze the deformation that occurred on the catcher components. Additionally, the BI was manually observed based on variations in the height of the FFB during harvesting. The results showed that an increase in the dropping height of the FFB caused an increase in potential force, which impacted the damage to the FFB. The potential force simulation results on the E-Bhar machine's catcher components ranged from 143.35 N to 2300.38 N, with BI values between 2.38 and 6.69. The maximum BI of 6.69 at a height of 10 m indicates damage approaching the critical value, thus threatening the quality of the FFB. The percentage of FFA ranged from 2.30% to 7.85%, exceeding the maximum limit of 5% set by the palm oil mill according to (SNI 01-2901-1992). These findings emphasize the advantage of using the catcher components in the E-Bhar machine to maintain good quality of the harvested FFB. Keywords: Bruise index, Catcher component, Deformation, Free fatty acids, Load testing.

Abstract

Improving the quality of B-35 biodiesel fuel is crucial, especially in distillation and flash point parameters that affect performance and safety. The objective of this study was to analyze the effect of oxygen ultrafine bubble application on the fuel characteristics of B-35 including cetane number, viscosity, density, flash point, distillation, and cloud point. Tests were conducted according to ASTM standards: D86 (distillation), D93A (flash point), D613 (cetane number), D445 (viscosity), D4052 (density), and D5773 (cloud point). The treatment was performed by injecting oxygen ultrafine bubble at a rate of 1, 3, and 5 l/min into 1.5 liters of fuel for 10–60 minutes. The results showed the highest distillation temperature of 339.7 °C at 1 l/min and 10 minutes, while the lowest temperature of 330.9 °C was achieved at 5 L/min and 60 minutes (control: 341.6 °C). The highest flash point of 72 °C occurred in the low oxygen injection rate and short duration, while the lowest was 64.5 °C in the high rate and long duration. The treatment increased cetane number from 58.6 to 60.8. The decrease in viscosity and density was insignificant but remained within standard limits. The cloud point decreased from 7.1 °C to 5 °C. UFB oxygen addition shows significant potential in improving the quality and combustion efficiency of B-35 fuel

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.
