The community utilizes this increased production, especially the UPPKS Flamboyan 3 Princi group, to be processed into various kinds of processed products. However, until now, processed sweet orange products have only focused on food and beverage products, such as orange juice. Meanwhile, the remaining by-products, the orange peel, are only processed into orange peel crackers, which are still very low in demand. Orange peel contains essential oils with the main component, limonene, which has many health benefits. This community service activity aims to utilize orange peel waste, which can be extracted from its essential oil content by a simple steam distillation method. The activities carried out were counseling on the production and packaging process of orange peel essential oil in a simple way. From this activity, partners showed enthusiasm for processing orange peel waste and tried to be able to carry out the essential oil extraction process independently. Keywords: extraction; essential oil; sweet orange peel

Abstract

Used cooking oil is widely considered waste because it can damage the environment and cause health problems. Meanwhile, used cooking oil can be used as a substitute raw material for Crude Palm Oil (CPO) in Indonesia's national biodiesel program. Indonesia has a remarkable ability to use used cooking oil as a raw material for making biodiesel. If the 1.2 million kiloliters of biodiesel made from CPO raw materials are exchanged with used cooking oil raw materials, it can save approximately Rp. 4.2 trillion. There are various process technologies in making biodiesel, including microemulsion, pyrolysis, and transesterification. Transesterification is a process in which triglycerides and methanol are reacted to create biodiesel and glycerol as a by-product. Transesterification using a homogeneous catalyst has advantages such as lower cost, relatively short processing time, and higher yield of biodiesel products. Transesterification using a homogeneous catalyst has the disadvantage of a more complex separation. This literature study aims to explain the method for biodiesel production and becomes a reference in terms of process selection in biodiesel manufacturing plants, especially from used cooking oil as raw material.

Abstract

The Covid-19 (Coronavirus Disease 2019) pandemic has had some effect on the development of children's education because they have to learn independently online. Online learning is a big challenge for schools, teachers, and parents because they are required to be able to manage and design learning media to achieve learning goals and prevent student boredom during online learning. This article describes one of the learning media for elementary school students by making animated videos that can be easily understood. The goal was to provide learning methods to attract students' interest in online learning during the pandemic. This learning model emphasized visualization and summary explanation of the material. Community service partners, in this case, are teachers at SD Sumberwindu I, Tanjung Anom District, Nganjuk Regency, and 5th-grade students. Activities are carried out by identifying school problems and training in making animated videos. While using the animated video, the learning purpose will be easy to achieve. This also increases the motivation of the students to be more active in learning by their shelf and seeking new knowledge related to the video. In this community service, we introduced learning materials in the form of animated videos and uploaded them to a YouTube channel. Those videos can be accessed either by teachers or students. This learning model was well-received and well-appreciated by the teachers and students.

Abstract

Feed is the most important thing in doing a tilapia fish farming. In a feed required appropriate and balanced nutritional content so that fish growth becomes faster. Shrimp waste and tarum leaves are an alternative raw material for the manufacture of tilapia feed because they have a fairly high protein content. The purpose of this study was to examine the comparative effect of adding the percentage of tarum leaf meal and EM-4 fermented shrimp waste on water content, ash content, protein content, fat content, and crude fiber content of feed. The research method used is using the EM-4 fermentation process on shrimp waste. The variations carried out were the concentration of the addition of EM-4 (14,16,18,20, and 22 ml) and the percentage of addition of Wet Shrimp Waste (WSW) and Tarum Leaf Powder (TLP) (90%WSW + 10%TLP, 80%WSW + 20%TLP, 70%WSW + 30%TLP, 60%WSP + 40%TLP, and 50%WSW + 50%TLP). The results showed that the addition of fermented WSW EM-4 and TLP had a significant effect on the protein, fat and crude fiber content, while the water and ash content did not have a significant effect. The best tilapia feed formulation results were obtained at a ratio of 60% WSW and 40% TLP using 18 ml of EM-4 with the results obtained for water, ash, protein, fat and crude fiber content each of 7.09%. ; 12.59%; 29.98%; 7.45%; and 3.49%.

Abstract

Black pepper is one of Indonesia's agricultural commodities, contributing foreign exchange to the country. However, the economic value of this commodity has decreased. It is influenced by the lack of diversified black pepper products, which of course, have a higher value than raw material marketing. One product diversification that can be developed is black pepper oil. In obtaining essential oils, appropriate methods and technology are needed so that the resulting product is of high quality and the process is carried out efficiently. The latest methods in extraction that are being developed are microwave and ultrasonic technology. Therefore, in this study, black pepper oil extraction was carried out using the microwave hydrodistillation method, whereas previously, ultrasonic pretreatment was given for the material. In this case, observations were made on the influence of extraction parameters. Based on the research, it was found that increasing the distiller size flask and ambient temperature could increase the percentage of essential oils yield. At the same time, the longer extraction time caused a decrease in yield. Decreasing the material particle size and increasing microwave power could cause an increase in yield up to a certain point. The best results in black pepper oil extraction were obtained under extraction conditions using a distiller size of 1000mL, extraction time of 60 minutes, at an ambient temperature of 30 oC, the particle size of 60 mesh, at a power of 450 W with a yield of 1.056%, with the characteristics of having a clear greenish colour and anRI of 1.480. These specifications comply with ISO 3061:2008 for essential oil from black pepper. Thus, these parameters can be considered in the black pepper oil extraction process to produce marketable products. As a suggestion for further research, modeling, and process scale-up can be developed.

Abstract

Leaves of citronella (Cymbopogon nardus L.) have pretty much essential oil. Essential oil from citronella leaves is generally extracted by conventional methods. Conventional method is still less effective. The problem can be overcome by using non-conventional methods in the form of UMAE (Ultrasound-Microwave Assisted Extraction). UMAE is an extraction process assisted by ultrasound and microwaves. NaCl solution can be used as a solvent in the UMAE method because NaCl has a large dielectric constant. The aim of this study was to examine the effect of extraction time and the addition of salt on the yield and color of essential oils produced using the UMAE. The extraction process begins with the raw material preparation stage, such as harvesting, size reduction, and drying. Then, pre-treatment was carried out using ultrasound for 5 minutes at 35oC with the addition of 2, 4, 6, 8, and 10% (w/v) salt. Pre-treatment results were followed by the extraction process using microwaves for 30, 45, 60, 75, and 90 minutes. The best results were obtained with the addition of 6% salt and 60 minutes of extraction time with a feed to solvent ratio of 0.1 with a yield of 1.975%. and the color is yellow.

Abstract

Ultrasound Microwave Assisted Extraction (UMAE) is an alternative to extracting clove essential oil by combining ultrasonic waves and microwaves to improve the efficiency and effectiveness of extraction. The purpose of this study is to examine the effect of microwave power and extraction time on the yield and density of clove essential oil. The cloves are reduced to a size of ± 0.5 cm and then dried using an oven for 60 minutes at a temperature of 70 °C. The pre-treatment process is carried out for 5 minutes with a temperature of 40 °C assisted by ultrasonic waves. After the pre-treatment process, the results obtained were then further extracted with microwave assistance with variable extraction times of 30, 40, 50, 60, and 70 minutes and microwave power of 150, 300, 450, and 600 Watts. The results showed that the addition of microwave power and extraction time had a significant influence on the yield value and density of clove essential oil. The best results of clove essential oil extraction using the Ultrasound Microwave Assisted Extraction method were obtained at 600-watt microwave power and at 70 minutes of extraction time with a yield value of 10.63% and a density of 1.0515 gr/ml.
