Abstract

The increasing demand for energy causes a decrease in the availability of fossil fuels. Biomass from oil palm waste, namely empty oil palm bunches, can be used as an alternative fuel. The torrefaction process converts biomass into environmentally friendly biopellets with high added value. In this study, the calibration of the K-type thermocouple sensor was carried out using Arduino Uno and testing of the automatic pellet torrefaction tool from empty palm oil bunches. This study aims to develop an automatic control system for the pellet torrefaction tool. The design of the automatic torrefaction tool uses a microcontroller with a gas stove energy source. The dimensions of the support frame are the torrefaction tube (24 cm x 28 cm), the servo motor frame (15 cm x 9.5 cm) and the dynamo support frame (26 cm x 6.5 cm). The tool box is square (50 cm x 50 cm). The torrefaction tube has a volume of 2,826 cm3, a diameter of 15 cm and a height of 16 cm. The results showed that the system successfully reached a temperature of 300°C for 30 minutes from the initial temperature. The temperature accuracy test produced an average value of 92.12%. The stability of temperature control also proved to be quite good in achieving the specified setting point. The water content of torrefaction pellets at a temperature of 150-300°C was around 1-2%. The hydrophobicity of torrefaction pellets at a temperature of 250-300°C after being soaked for 24 hours had a clearer color and remained intact.

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.
