Abstract

Biomass is organic material produced from the process of photosynthesis. Biomass can be produced directly as a product or waste from processing agricultural or plantation products. One of the most abundant biomass is the waste generated from oil palm processing, including oil palm empty fruit bunches (OPEFB). Basically, OPEFB waste is only used as natural mulch or only disposed of in oil palm plantations. There are very few processing methods that convert into uniform shape and size biomass pellets, biomass pellets require an additional process called torrefaction, this is done to make bioenergy utilization more optimal. The quality of biomass pellets can be improved through torrefaction, which is a heat treatment process at a temperature range of 200°C–300°C under limited oxygen conditions. This study aims to examine the effect of torrefaction on the characteristics of OPEFB pellets. Pellet torrefaction uses a rotary reactor tube, a device that performs torrefaction with a tube that rotates 360º on a support shaft with the help of a transformer. Torrefaction temperatures applied were 220°C, 240°C, and 260°C with 15, 25, and 35 minutes. Pellet testing includes changes in chemical composition. The results showed that the water content of the pellets decreased from 10.57% to 1.64%. The water absorption test also showed that the torrefaction pellets were more resistant to water, so it would be very beneficial when the pellets were stored in humid conditions. Torrefaction causes a decrease in cellulose content, hemicellulose, and an increase in lignin content. Torrefaction with reactor tubes can improve the quality of EPEFB pellets and increase the added value of the product.

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

Continuous consumption of fossil fuels can cause fuel prices to rise and potentially cause shortages. One alternative renewable energy that can replace fossil fuels is biomass pellets. The use of manual biomass pellet stoves has constraints in controlling the amount of biomass burned, the amount of heat released by the stove, combustion efficiency, safety, and wasteful use of pellets. The purpose of this study was to develop a biomass stove using an automatic control system as a substitute for gas or electric stoves. This stove has the same principle and working method as gas stoves in general, but the pellet fuel is solid. This technology controls the temperature through the integration of temperature sensors, fan blowers, screw feeders, and heat insulators automatically. The results showed that the stove temperature value with the coefficient of determination value from sensor calibration 1 was R2 = 0.9945, sensor calibration 2 obtained the value R2 = 0.9956, the R2 value in sensor calibration 3 was 0.9946, and sensor calibration 4 obtained the value R2 = 0.9927. In the system response test, the device was able to reach a temperature of 300°C in 450 to 780 seconds. Stability testing for setting points 100°C, 200°C, and 300°C were 0.98, 0.82, and 0.53, respectively. The accuracy of the device was 92%. In the execution speed test, it took 2.5 to 4 seconds for the pellets to enter the fuel furnace.

Abstract

Rice is the main commodity processed into rice, as a staple food for the people of Indonesia. Pests and diseases can cause decreased production to crop failure. The method used by farmers is pest control by spraying chemical pesticides. However, chemical pesticides have serious impacts on plants, increased immunity for pests, increased chemical residues in crops that threaten human health, and environmental pollution. The objective of this study is to design an integrated high-tech trap that is effective, efficient, cost-effective, durable, safe, environmentally friendly (zero-emission), and low in operational costs, with the ultimate goal of enhancing farmers' income. This automatic pest trap embeds a microcontroller, infrared sensor, fan and solar panel. Observations were made on 4 tools, namely complete lures, yellow LED, lights and pheromones. Based on the observations, Scotinophara coarctata and Nilaparvata lugens were identified as the most commonly trapped insect pests in rice fields. The insect's fall speed was fast, namely 1 minute 4 seconds with good stability. Insect readings came in higher on the complete lure due to the combination of three lures, each of which has its own insect attraction. The effectiveness of insect capture on the complete automatic insect trap was the highest at 84.47%.
