Abstract

Antioxidant activity test of a combination of methanol extracts of meat remek leaves (Hemigraphis colorata w. bull) and kratom leaves (Mitragyna speciosa Korth) using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) silencing method with vitamin C as a positive control was analysed by UV-Vis spectrophotometry. The methanol extract of remek leaves contains flavonoids, triterpenoids/steroids and phenolic compound while the methanol extract of kratom leaves contains triterpenoids, flavonoids, alkaloids, saponins and phenolic. The combination of the two extracts gave the highest % inhibition in the 1:1 ratio. The IC50 values of methanol extracts of meat remek leaves, kratom leaves are 70.61; 33.43 ppm indicating antioxidant activity in the strong and very strong categories and the combination is 38.08 indicating the combination index is strong antagonis

Abstract

The slopes of Mount Argopuro are naturally rich in inactive volcanoes in Indonesia. The surrounding community uses this area as a place for economic livelihoods. One of the dominant economic sectors in which the surrounding community chooses to meet its living needs is the agricultural sector, particularly the livestock sector. Community empowerment activities aim to 1) Increase understanding of business innovation to increase the added value of managing livestock waste; 2) Build pioneering business institutions through Community Business Groups; and 3) Initiate business marketing and sustainability. The method of implementing community empowerment includes socialization and training with four criteria: 1) Providing material on the importance of institutions; 2) Product diversity as a requirement for developing livestock waste processing businesses; 3) Business Development Practices; and 4) Strengthening business management. Community empowerment activities are equipped with activity evaluation methods through surveys that provide pre-test and post-test treatments to the unemployed community in Panti Village. The results of the Community Service show that the unemployed community in Panti Village can understand the benefits of strengthening institutions based on business legality and the creation of AD/ART as a basic requirement for the formation of institutions. The unemployed community can know, understand, and develop skills in the diversity of livestock waste processing that have not been utilized either economically or ecologically. An unemployed community can create packaging designs, promotions, networking, social media accounts, product trust concepts, and management to improve business performance. To improve the sustainability of the program and product absorption, the community empowerment team cooperates based on business transparency with the business incubator of the Faculty of Economics and Business Laboratory, University of Jember to improve networking and product expansion in the future.

Abstract

The use of chitosan from maggot (Hermetia illucens) exuvia as an edible coating for tomatoes (Lycopersicon esculentum) and an edible film with honey added as an antibacterial agent was investigated. This study aimed to determine the yield of chitosan from black soldier fly (BSF, Hermetia illucens) maggot exuviae as an edible coating. The chitosan was produced from chitin by deacetylation, and its effect on the weight loss and vitamin C levels of tomatoes for 7 days after treatment was investigated. The chitosan coating was characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy. The antibacterial activity was evaluated using a disk diffusion method. The result showed that by deacetylation, conversion of chitin produced chitosan with a yield of 72% and a deacetylation degree of 75.05%. The chitosan coating significantly affected the weight loss of tomatoes, with the best concentration being 2%. However, the treatment did not significantly affect the decrease in vitamin C levels. The edible chitosan film from BSF maggot exuviae with added honey had a thickness, water content, and water vapor transmission rate of 0.156 mm, 16.9913%, and 30.45 g/m2/24 hours, respectively. SEM characterization showed a relatively dense surface structure, which was slightly smooth and porous. Regarding antibacterial activity, the edible chitosan film inhibited Staphylococcus aureus with an inhibition zone of 10.37 mm; however, Escherichia coli was not inhibited. These results suggest that chitosan from BSF maggot exuviae has potential as an effective edible coating for reducing weight loss in tomatoes despite showing limited antibacterial properties.
