Using traditional tools and manual work by small farmers in rural and developing areas is routine in processing agricultural land, especially planting plant seeds. This working model includes moderate to severe workload due to additional workload, namely sunlight when planting. In addition, work is carried out with non-ergonomic work postures, namely non-natural work postures. This causes musculoskeletal complaints to workers due to the non-harmonious tools with workers. Workers' productivity will decrease and have the potential to reduce the quality of life of small farmers themselves. To help the manual work of small farmers to create effective, comfortable, safe, healthy, efficient, and sustainable jobs, an ergo-mechanical application is needed to design work tools. This application is based on studies conducted on the design of work tools from several libraries or research results. The ergo-mechanical study is an integrated system that applies ergonomic and mechanical principles. The ergo-mechanical application produces ergonomic work tools that are comfortable to use by workers, and technical standards include material, product, and service requirements. Mechanically, the application through technical drawings, mechanical planning, and work tool materials to get a strong, lightweight, and safe work tool from hazardous substances, according to technical specifications. Technical standards are related to data sheets or specifications that describe the technical characteristics of a work tool. On the specifications of the work tool design, specifications can be added that the work tools are ergonomic. Ergonomic work tools can produce effective, comfortable, safe, healthy, and efficient work. This results from the compatibility between work tools and workers or the harmonious work tools with workers. Ergo-mechanical creates comfort in work that affects the increase in productivity and quality of life for workers.

Limbah biomassa di Indonesia sangat berpotensi sebagai sumber energi kalor ruang pengering produk pertanian. Penelitian ini bertujuan untuk memanfaatkan limbah sekam padi menjadi sumber kalor untuk pengeringan produk pertanian serta mengetahui unjuk kerja ruang pengering dengan bahan bakar sekam padi. Penelitian diawali dengan pembuatan rancang bangun mesin pengering yang dilanjutkan dengan pengujian unjuk kerja. Mesin pengering memiliki komponen utama berupa tungku pembakaran, ruang pengering, blower, dan suction fan. Pengujian unjuk kerja mesin pengering dilakukan untuk pengeringan cabai. Tujuan penelitian adalah untuk mengetahui pengaruh mode aliran konveksi flue gas terhadap efisiensi dan konsumsi energi spesifik (SEC) mesin pengering. Hasil penelitian menunjukkan bahwa mesin pengering dapat beroperasi dengan baik. Efisiensi mesin pengering aliran konveksi paksa lebih tinggi dari efisiensi mesin pengering aliran konveksi alami dan sebaliknya SEC mesin pengering aliran paksa lebih rendah dari SEC mesin pengering aliran konveksi alami. Efisiensi mesin pengering mencapai 25,12% untuk aliran konveksi paksa dan 10,50% untuk aliran konveksi alami. Sedangkan SEC mesin pengering aliran konveksi paksa sebesar 198370,37 kJ/kg uap air dan 918171,42 kJ/kg uap air untuk aliran konveksi alami.

This study aimed to enhance the thermal characteristics of rice husk biomass through torrefaction conducted in a fixed-bed reactor. A novel approach was employed by circulating the gas produced within the system, instead of using traditional nitrogen. The torrefaction process took place at temperatures ranging from 200 to 320 °C, with different residence times of 10, 20, and 30 min for heat exchange. Quantitative analysis of the torrefied biomass revealed several notable improvements. The higher heating value of the biomass increased significantly, reaching 23.69 MJ/kg at a temperature of 320 °C and a residence time of 30 min. This enhancement indicates the effectiveness of torrefaction in increasing the energy content of the biomass. Furthermore, the torrefied biomass exhibited a remarkable reduction in hygroscopicity, with reduction by as much as 92 wt% compared to raw rice husk biomass. This reduction implies that the torrefied biomass is more resistant to moisture absorption, making it more stable and suitable for various applications. The torrefaction process in the fixed-bed reactor yielded a torrefied biomass with a production yield of 76 wt% (RH-320, RT30). This yield showcases the potential of the employed technique for producing a substantial amount of high-quality torrefied biomass. The resulting biomass holds great promise for diverse applications. It can be utilized for industrial steam production, contributing to the efficient use of biomass resources. Moreover, it could serve as an alternative fuel source for biomass power plants, offering a sustainable energy solution. Overall, this study demonstrates the effectiveness of the proposed torrefaction method in enhancing the thermal characteristics of rice husk biomass. The improved energy content and reduced hygroscopicity make torrefied biomass a valuable resource for various industries, promoting the utilization of biomass as a renewable energy source.
