Abstract

The PbM-KP service activities carried out by the PPM Team with a group of women fromCintaraja Village and Cipakat Village, Singaparna District, Tasikmalaya Regency, is one form ofthe Tri Dharma Perguruan Tinggi task that every lecturer must carry out.The purpose of PbM-KP dedication is to improve the mindset, skills of cultivating organicplants, improve and improve the family economy by seeking the availability of foodstuffs in theiryards, especially in the current Covid 19 pandemic conditions.Activities in the PPM program are socialization and demonstration of planting mediaprocessing, organic fertilizers and aquaponics of mina kale in the cultivation of fish in buckets,caysim / mustard greens, ginger, turmeric and lemongrass, minimizing the impact of a shortage ofspices and protein as a source of family health. Because with this application, food security can beaccelerated more quickly in the community affected by the Covid-19 pandemic.The output to be achieved from this PbM-KP community service activity is in the formof assistance to the family economy, publication of an organic vegetable farming manual in theyard, publication in a journal or national proceeding with ISSN not accredited and publication inthe local print media

Abstract

The emergence and spread of pathogens is one of agriculture's problems. Rhizopus stolonifer is the pathogen to be on the lookout for because it causes rhizopus loose rot disease. The pathogen must be dealt with immediately because it can result in losses of up to 40%. Integrated plant disease management (IPDM) is the approach being promoted. The application of biological agents or biocontrol is one solution that supports IPDM. The challenge is met by biological agents through the production of secondary metabolites. The endophytic microorganisms found in Java ginseng (Talinum triangulare) are one source of secondary metabolites. Thus, the purpose of this study was to investigate whether endophytic microorganisms in Javanese ginseng roots have the ability to combat the pathogen R. stolonifer. The experimental method involved analyzing the secondary metabolite from the endophytic microorganism in ginseng in vitro. phytochemical and zone of inhibition were the two types of test that were being performed. The obtained result was a set of extract that contains triterpenoid and alkaloid. In addition, extract B (FN-1) had the strongest inhinbitiom zone against R. stolonifer.
PENGARUH CASGOT LARVA BLACK SOLDIER FLY (BSF) SEBAGAI MEDIA TANAM TERHADAP PERTUMBUHAN BIBIT KOPI ROBUSTA (Coffea robusta) Nirwanto, Yogi; Yulianto, Yanto; Hartini, Elya; Akmalludin, Iqbal

Abstract

PENGARUH CASGOT LARVA BLACK SOLDIER FLY (BSF) SEBAGAI MEDIA TANAM TERHADAP PERTUMBUHAN BIBIT KOPI ROBUSTA (Coffea robusta). Kotoran larva maggot merupakan residu hasil biokonversi limbah organik dari larva Black soldier fly (BSF). Kotoran larva BSF berkontribusi dalam meningkatkan kemampuan tanah untuk menahan air dan udara, serta meningkatkan retensi nutrisi. Penelitian ini bertujuan untuk mengetahui kandungan dan takaran pupuk organik limbah maggot yang sesuai untuk pertumbuhan bibit Kopi Robusta (Coffea robusta). Kopi Robusta merupakan salah satu komoditas yang memiliki nilai ekonomi yang tinggi. Salah satu kendala dalam pertumbuhan bibit kopi Robusta (Coffea robusta) secara generatif adalah tumbuhnya lambat, kemungkinan diakibatkan karena unsur hara yang terkandung dalam media tanam kurang optimal dan juga benih kopi memiliki kulit biji yang keras. Penelitian ini bertujuan untuk mengetahui pengaruh interaksi antara media tanam dari kotoran maggot dan takaran pupuk kotoran maggot berapakah yang memberikan pengaruh paling baik terhadap pertumbuhan benih kopi robusta. Metode yang digunakan dalam percobaan adalah Rancangan Acak Kelompok (RAK) yang terdiri dari 6 perlakuan dan diulang sebanyak 4 kali sehingga terdapat 24 petak unit percobaan. Hasil penelitian menunjukkan perlakuan komposisi media tanam yang berpengaruh nyata terhadap pertumbuhan bibit kopi Robusta (Coffea robusta) yaitu pada perlakuan media kotoran larva BSF dan tanah (1:1) dan perlakuan kotoran larva BSF, tanah dan arang sekam (1:1:1) yang memberikan peningkatan pada parameter diameter batang tanaman, jumlah daun, dan tinggi tanaman.

Abstract

Chili anthracnose, caused by Colletotrichum spp., remains a major threat to crop productivity and fruit quality worldwide. The increasing resistance of fungal pathogens to synthetic fungicides highlights the need for sustainable, plant-based alternatives. This study provides computational insights into the antifungal mechanisms of coumarin and hexanol, two major bioactive compounds derived from Ageratum conyzoides and Cyperus rotundus. Molecular docking and molecular dynamics simulations were employed to examine the interactions of these compounds with key Colletotrichum proteins, including calmodulin, PETFP cutinase complex, and chitin deacetylase. The docking results revealed that coumarin exhibited stronger binding affinities and more stable conformations within the enzyme active sites than hexanol, forming multiple hydrogen bonds and π–π stacking interactions with catalytic residues. Molecular dynamics analyses further confirmed the structural stability and compactness of coumarin–protein complexes, indicating its potential to disrupt fungal enzymatic functions critical for pathogenicity. These findings suggest that coumarin, in particular, may serve as a promising lead compound for the development of eco-friendly antifungal agents. The study contributes to a molecular-level understanding of plant-derived antifungal mechanisms, supporting future research into the rational design and optimization of biofungicides for sustainable agriculture.
