Abstract

Almost all regions in Indonesia do not have a large availability of labor, therefore mechanical devices are needed to replace them, especially in terms of harvesting shortages of labor can be replaced by mechanical devices such as combine harvester rice harvesting machines. Rice harvesting machine Combine Harvester type ridding brand Crown Type CCH-2000 Star is an agricultural machine that functions to harvest rice through the stages of linking, directing, cutting, bringing the results of pieces, shedding, and cleaning the grain which is done in an integrated manner in one process. The purpose of this study was to find out the performance of the Combine Harvester machine for rice harvesting. This research consists of three main stages, namely machine and land preparation, machine performance testing and data analysis. The parameters observed were work speed, theoretical field capacity, effective field capacity, field efficiency, grain harvest losses, and fuel consumption carried out in May in Sragi District, South Lampung using Combine Harvester machines. The results showed that the engine working speed was 3.38 km/h while the tests carried out by the Center for Agricultural Mechanization Development were 3.90 km/hr. Effective field capacity of 0.77 ha/hour, theoretical field capacity of 0.33 ha/hour, and field efficiency of 42.85%. The percentage of harvest shrinkage in an area of 1 hectare is 0.9% better than the loss with conventional harvesting of up to 18.75%. Fuel consumption when harvesting with an area of 1 ha with 2100 rpm consumes fuel at 16.8 liters/ha. Keywords: Combine Harvester, Machine Performance, Previous Research, Rice.

Abstract

This study aims to examine the effect of different percentages of rice straw as a blending material in biocoal briquettes on their physical properties and combustion performance. Four variations of rice straw content were used: 16%, 31.9%, 47.7%, and 63.7%. The results showed that briquette density decreased with higher rice straw content, from 765.13 kg/m³ at 16% to 466.34 kg/m³ at 63.7%. Mechanical strength also varied: tensile stress reached 100,109.99 N/m² at 16% and dropped to 85,480.03 N/m² at 63.7%, while compressive strength ranged from 71,902.06 N/m² to 62,909.68 N/m². Drop tests indicated that higher rice straw content generally reduced impact resistance. Combustion tests revealed that briquettes with higher rice straw content ignited faster and burned more quickly, with a maximum combustion rate of 2.81 g/min for the 63.7% mixture compared to 1.73 g/min for the 16% mixture. However, the calorific value decreased as rice straw percentage increased, from 4,968.53 kcal/kg to 4,011.97 kcal/kg, while moisture content rose from 26.40% to 37.93%. Analysis of variance (ANOVA) for combustion rate confirmed a significant effect of rice straw proportion (F = 10.93; BNT 5% = 0.2998). Compared to conventional briquettes, rice straw biocoal briquettes showed competitive combustion performance but slightly lower mechanical durability. This study demonstrates the potential of utilizing rice straw as an alternative biomass material to produce environmentally friendly biocoal briquettes with acceptable physical properties and enhanced combustion rates. Keywords: Biocoal briquettes, rice straw, density, tensile stress, compressive strength, combustion rate, calorific value.

Abstract

Insect pests generally attack horticultural plants and carry viruses that are harmful to plants. For this reason, a tough and precise control system is needed to be able to control insect pests. Researchers from the University of Lampung have designed a semi-automatic insect pest trapping device utilizing solar energy that can control the development of pest insects in horticultural crops. Technology that is transformed to the public has affordable assembly costs with great benefits to reduce the effects of crop failure from insect pests. The aim of this service is technological transformation through continuous socialization, training, manufacturing, and maintenance of semi-automatic pest traps from the University of Lampung. This service is carried out for horticultural producers in the Maju farmer group, Kota Gajah Subdistrict, Central Lampung. The working system of this tool At night, ultraviolet lamps and TL lights installed are able to attract insect pests to come around the lights and fall into the trap. Whereas during the day, the scent of attractant and fermomon is able to attract insect pests to be ensnared. The technology used has been integrated with electricity sources from renewable energy, namely solar cells.

Abstract

The utilization of biomass as a renewable energy source has gained increasing attention as an alternative to fossil fuels. This study aimed to evaluate the effect of tree branch biomass proportion on the physical characteristics and combustion performance of biocoal briquettes produced from biomass–coal blends. Four briquette formulations containing 16.0%, 31.9%, 47.7%, and 63.7% tree branch biomass were prepared and tested for density, impact resistance, tensile strength, compressive strength, and combustion rate. The results showed that biomass composition significantly affected the physical and combustion properties of the briquettes. The highest density was obtained at 16.0% biomass content (940.84 kg/m³), while the lowest density was observed at 47.7% biomass content (883.08 kg/m³). The briquette containing 47.7% biomass exhibited the best mechanical properties, characterized by the lowest number of fragments after impact testing (3.4 pieces), the highest tensile strength (115,710.61 N/m²), and the highest compressive strength (168,541.37 N/m²). Meanwhile, the highest combustion rate was achieved by the briquette containing 63.7% biomass, reaching 2.37 g/min. Compared with commercial coal briquettes, the combustion performance of the 63.7% biomass briquette approached that of super briquettes (2.57 g/min) and exceeded that of pure coal briquettes (2.09 g/min). Overall, a biomass proportion of 47.7% was considered optimal in terms of physical and mechanical properties, while 63.7% biomass provided the best combustion performance. These findings demonstrate the potential of tree branch biomass as a sustainable feedstock for biocoal briquette production.
