Abstract

Used cooking oil is cooking oil that has been damaged. Purification of used cooking oil can utilize additional adsorbents as additional materials for the adsorption process. This research aims to determine the effect of adding granulated activated charcoal adsorbents and kepok banana peel powder on the quality of used cooking oil and determine the best treatment based on the specified test parameters. The used cooking oil purification method used is neutralization and bleaching. Each treatment will be repeated 3 times and the data will be processed using the SPSS application. The research results show that purified used cooking oil has a brightness value (L*) ranging from 64.30 – 62.67. The yield value for each treatment ranged from 73.137% - 62.093%. The water content value in each treatment has a value ranging from 0.013% - 0.046%. The free fatty acid value in each treatment ranged from 0.188% - 0.137%. The peroxide value in each treatment ranged from 6.00 – 2.33 mEk O2/kg. Meanwhile, the organoleptic parameter for aroma has a value between 4.0 – 4.9 and color has a value between 3.8 – 4.3. So the best treatment using MPE is the A2B3 treatment (15 gr : 10 gr).

Abstract

Potatoes, as an agricultural vegetable crop, are highly susceptible to damage during post-harvest and distribution processes. Post-harvest activities involve multiple actors, including farmers, agents, market traders, and street vendors. The involvement of numerous actors in the supply chain can lead to damage that affects potato quality. This study aims to analyze the risks of quality loss during post-harvest processes and design handling strategies to reduce supply chain risks for potatoes. The research employs the House of Risk (HOR) method, which consists of two phases. The findings reveal that the types of quality degradation affecting potatoes are primarily due to mechanical damage, classified into abrasion, cracking, puncture, cutting, bruising, splitting, tearing, and skin cracking. These risks were identified as being caused by 10 risk agents. Among them, four key risk agents were selected and analyzed to determine appropriate mitigation strategies. The recommendations for risk management and mitigation actions are expected to minimize the risks of mechanical damage in the potato supply chain in Magetan Regency.

Abstract

Bioplastics are alternative packaging made from natural polymers, which have the properties of being biodegradable, reduce environmental pollution and are safe for health because they do not contain toxic substances. Bioplastics are made from natural materials. It is hoped that the existence of environmentally friendly plate products can reduce the use of plastic plates in the community so as to reduce the accumulation of excessive plastic waste. The addition of bagasse to environmentally friendly plate products is expected to improve their mechanical properties. There are 3 variations of bagasse fiber size used, namely 60 mesh, 1mm and 3mm. The purpose of this study was to determine the effect of bagasse size variation on tensile strength, elongation, water resistance and biodegradability of eco-friendly plates and to get the best formulation of bagasse size variation as raw material for making eco-friendly plates. The manufacture of environmentally friendly eco-friendly plates used a completely randomized design with one factor and 3 repetitions. Observations made included biodegradability test, water resistance test, tensile strength test and elongation test. The results showed that of the three treatments, the variation of adding 60 mesh bagasse (A) was the best formulation for environmentally friendly plate products. Bioplastic products for plate shape are expected to have strong mechanical properties and can be degraded in the environment.

Abstract

Red chilies have a relatively short shelf life and are highly perishable. Red chili is one type of vegetable with a water content (60 - 90 %) at the time of harvest and an increase in respiration rate. Therefore, it is necessary to pack a coating that can reduce and suppress respiration and transpiration rates to prevent vegetable damage. One potential way to reduce the damage to red chilies is by applying edible coatings. Edible coating is one technique that can be developed and applied to maintain quality and extend the shelf life of red chili. This study aims to determine the quality characteristics of red chili (Capsicum annuum L) before and after coating edible coating. In addition, to analyze the effect of Konjac flour concentration on the quality characteristics of red chili (Capsicum annuum L) with the addition of chitosan and to find out the best treatment for the application of edible coating with the basic ingredients of Konjac flour with the addition of chitosan. This study used a completely randomized design (CRD) and three replications. The treatment in this study was the storage time of coated red chilies edible coating for 1, 3, 6, and 9 days. The results showed that the storage time of coated red chilies edible coating affects the pH, water content, weight loss, respiration rate, and color. The analysis of the characteristics of red chilies showed that the coating done on red chilies can reduce and suppress the process of respiration rate.

Abstract

The economy has become a vital aspect of the Nation’s sustainability, the same goes for villages. The Economic value of a village becomes a key success indicator of synergy between the village's citizens and institutions. Olean Village is known for its tourist spot “Karang Kenek 26'' or KK26, which has become one of the important cores for the economy and SME empowerment. However, due to natural disasters, a tornado in 2022, and the COVID-19 pandemic, various sectors in Olean cease to operate. Aligning with the “Temu Inklusi Nasional 2023” event and the revitalization of KK26, KKN students become an important agent of change in SME empowerment in Olean Village. For effective empowerment, KKN students conduct an analysis and observation to simplify the synergy process between institutions and the citizens, thus developing a program consisting of socialization, service, training, and organization reinforcement.

Abstract

This study discusses the analysis of work posture on all activities of workers who produce coco fiber in CV. Sumber Sari is located in Lembengan Village, Jember Regency. The production processes that are currently operating are the jockey, drying, sieving, and pressing processes. Work activities are carried out repeatedly, causing complaints to workers. These complaints arise due to non-ergonomic posture causing pain in several parts of the body felt by workers. The purpose of this study was to determine the level of risk and the percentage of complaints experienced during the production process. The methods used are the Standard Nordic Questionnaire (SNQ) and the Rapid Entire Body Assessment (REBA). The results of the research from the SNQ questionnaire on the manufacture of coco fiber, the body segments of workers mostly experience complaints on the back, waist and thighs. Research using the REBA method has a very high level of risk in jockey, sieving, and pressing workers (A4 and A5).Keywords— musculoskeletal disorders, working posture, SNQ, REBA

Abstract

Pakcoy (Brassica rappa L.) is a horticultural commodity with great potential that requires further processing to preserve quality and extend their shelf life. One of the commonly used advanced processing techniques is the pasteurization method, which uses a thermal process. The thermal process is known to cause quality degradation in pakcoy juice, especially its chlorophyll content. This study is to determine chlorophyll pigment degradation kinetics in pakcoyjuice during the thermal process. The kinetics of chlorophyll degradation followed first-order reactions, with an activation energy of 38.24 kJ/mol. The ? value ranged from 114.943 to 384.615 minutes, the ? value was 60.61°C, and the reaction rate constant (?) increased with increasing temperature. The results of this study emphasized the importance of controlling the temperature and duration of the thermal process to maintain the quality of chlorophyll pigments in pakcoy juice.
