Abstract

Indonesia is the most mangrove-rich country, both in terms of area quantity and number of species. Mangrove plants have potential as a source of medicinal compounds. Bruguiera gymnorrhiza is a type of mangrove plant which is a source of medicinal plants from the Rhizoporaceae family. Ethanol extract of the stem bark of B. gymnorhiza has been known to have cytotoxic activity with an IC50 of 508.19 µg/mL against myeloma cancer cells (Rahmah, 2021). The aim of this study was to determine the toxicity of lindur fruit peel extract (B. gymnorrhiza) on Artemia salina Leach shrimp larvae. Lindur fruit peel extraction was carried out by maceration method using methanol solvent which was then fractionated with n-hexane and ethyl acetate as solvent. All extract fractions obtained were then tested for toxicity against shrimp larvae Artemia salina Leach by BSLT (Brine Shrimp Lethality Test) method. Extract fractions with the highest toxicity were identified for their bioactive compounds using UV-Visible and FT-IR spectrophotometers. The results of the toxicity test showed that the lindur fruit peel extract was toxic to A. salina L. and the most toxic fraction was the n-hexane fraction with an LC50 value of 34.109 ppm. The results of the analysis using UV-Visible and FT-IR spectrophotometers the active compound in the hexane fraction of lindur fruit extract (B. gymnorrhiza) contains terpenoid which has double bond conjugated that showed by the existence of an electronic transition of π →π* that was conjugated and there are clusters of -OH, C=O, C=C, aromatic, C-H and C-O groups.

Abstract

Salem District is one of the largest coffee commodities in Brebes Regency. This significant potential has yet to provide a meaningful contribution to the income of coffee farmers, especially in Gunung Jaya village, Salem District. The low income of coffee farmers is due to the fact that they still sell their coffee products in the form of cherry. Over time, in 2018, farmers began to develop small-scale and simple coffee processing from green beans to roasted beans and coffee powder, pioneered by the SME "Lulumpang Kopi". They still use simple tools and often have to travel out of town to obtain the desired coffee powder. Lulumpang Kopi can produce 100-150 packages of coffee weighing 100 grams. Seeing this potential, the Community Partnership Empowerment team (PKM) from the University of Civilisation and UNSOED, funded by DIKTISAINTEK, is conducting community service this year 2025 using training methods, workshops, and appropriate technology grants. Thus, technology has been granted in the form of 1 Huller machine with a capacity of 150kg/batch, 1 BBM Grinding machine with a capacity of 10kg/batch, and scales. This assistance aims to enhance farmers' capabilities to achieve greater economic independence and improve their competitiveness in the market. As a result of this activity, partners were able to increase the capacity and quality of coffee farmers' production through the grant of equipment such as huller, BBM grinder, and digital scales, making the processing faster, more efficient, and yielding better coffee compared to traditional methods. In addition, the training participants also demonstrated an increase in knowledge through pre-tests and post-tests, rising from 66.5% to 77.3%, an increase of 13.8% from the 40 participants who attended.

Abstract

Coffee is one of the top 3 potential regional superior products in Brebes Regency, in addition to salted eggs and shallots. Sirampog sub-district is the most dominant sub-district that produces Arabica type coffee because Sirampog sub-district is at an altitude above 1000 meters above sea level. The lack of post-harvest technology and conventional coffee processing are the main obstacles for partners in maintaining quality and increasing quantity. This has become a problem for partners in meeting the increasing market demand. The process of drying the initial drying of coffee which is done traditionally requires a lot of energy, is impractical, has the potential to reduce the flavor of coffee due to odor absorption and is difficult to do in the rainy season. Based on these conditions, the village empowerment team (PDB) of Universitas Peradaban and Unsoed funded by DRTPM in the first year (2024) conducted community service through various trainings, workshops and appropriate technology grants. In the implementation of appropriate technology, green house technology measuring 7 m x 10 m2 has been granted with a drying capacity of 2 tons. The drying results are efficient because farmers no longer need to lift and dry the coffee in the afternoon or when it rains. Farmers only need to turn it over so that the dryness is evenly distributed. The greenhouse system also dries faster because the heat is stored and trapped, and the capacity increases 3 times because the drying is arranged in 3 layers.
