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

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%.

Abstract

Free fatty acid is an important parameter in determining the quality of crude palm oil. High free fatty acid content can reduce oil quality and cause economic losses in palm oil processing. The conventional method commonly used to determine free fatty acid content is acid-base titration, but this method requires chemicals, laboratory equipment, and relatively long analysis time. This study aimed to design a portable device for rapid detection of free fatty acid content in crude palm oil using pH meter, turbidity meter, and artificial neural network. Oil samples were obtained from oil palm fruitlets with different physical damage levels. Free fatty acid content was measured using titration, while pH and turbidity were used as input variables in the artificial neural network model. The results showed that pH had a relationship with free fatty acid content with a coefficient of determination of 0.3516, while turbidity had a stronger relationship with a coefficient of determination of 0.7636. The best artificial neural network model was obtained using the tansig-logsig-logsig activation function, with R² of 0.9501 and RMSE of 0.6390 in calibration. In the testing stage, the model produced R² of 0.8061 and RMSE of 1.9222. The developed prototype can be used as a rapid method to estimate free fatty acid content in crude palm oil.

Abstract

This study evaluated the effect of ginger addition on the physical characteristics and sensory acceptance of cascara tea produced from Robusta coffee pulp. Coffee pulp is an agricultural by-product that can be processed into a value-added beverage product. Ginger was added to improve the sensory profile of cascara tea, particularly aroma and taste. The study used a single-factor Completely Randomized Design with six ginger concentrations, namely 5%, 10%, 15%, 20%, 25%, and 30% based on the weight of cascara. Each treatment was repeated three times. The observed parameters included moisture content, specific gravity, sediment content, and sensory acceptance. The results showed that ginger concentration significantly affected moisture content, but did not significantly affect specific gravity and sediment content. Sensory evaluation showed that the addition of 10% ginger produced the highest acceptance score compared with other treatments. Excessive ginger concentration tended to reduce panelist preference because the pungent ginger flavor became dominant. Based on the observed physical and sensory characteristics, the addition of 10% ginger was considered the most acceptable formulation for cascara tea made from Robusta coffee pulp. Further studies are required to analyze bioactive compounds, antioxidant activity, microbial safety, and storage stability before the product can be claimed as a functional beverage.
