Abstract

Diseases are one of the major challenges in crop production which can lead to significant economic losses. Ironically, while having multiple negative impacts, synthetic chemical pesticides are considered the main strategy in tackling plant diseases. Trichoderma asperellum is one of the potential fungal species that can inhibit numerous plant diseases. This study reconfirmed the morphological characteristics of Trichoderma isolates obtained and identified it by molecular techniques. In addition, the inhibitory activity of the isolates was tested in vitro against the mango pathogens Colletotrichum asianum and Diaporthe pseudophoenicicola. The results showed that isolate T4 was identified as Trichoderma asperellum. Isolate T4 was able to inhibit C. asianum and D. pseudophoenicicola by 28.19% and 15.64%, respectively. Therefore, this isolate can be used as a biological agent to control plant pathogens in an environmentally friendly, sustainable manner, and as an alternative to synthetic chemical pesticides.

Abstract

Chitinase enzymes are enzymes that can hydrolyze chitin polymers into chitin oligosaccharides or N-acetylglucosamine synergistically and sequentially. This enzyme is naturally produced by bacteria, fungi, plants, and animals. The magnitude of the potential possessed by chitinolytic bacteria with their living environment spread in various sources, does not rule out the possibility of isolating chitinolytic bacteria from leachate water, shrimp pond water, and rhizosper root soil. This study aims to isolate and identify the morphology of chitinolytic bacterial colonies obtained from the exploration results. The research was conducted with the exploration method and then analyzed descriptively. The results of the study obtained 22 isolates of chitinolytic bacteria from the exploration results with 11 isolates with the code TAC is an isolate from the roots of chili soil, 8 isolates with the code ALT comes from leachate water, and 3 isolates from shrimp ponds coded TUC. The results of morphological observations of bacterial colonies obtained the cell shape of the bacterial colonies were 17 cocci and only 5 were bacilli. Isolates are mostly white with milky white and bone white color and 7 isolates with red and yellow color variations. The results of gram staining showed 10 bacterial isolates were gram negative and 12 isolates were positive with bacterial cell shape mostly cocci.

Abstract

Land in Tawangsari District, Sukoharjo Regency had a limiting factor in the form of water availability. One of the local commodities cultivated for generations on dry land in this region is gembili (Dioscorea sp.). However, the gembili cultivation process has not produced optimal productivity and is threatened with extinction. Therefore, gembili cultivation and use of dry land need to be optimized by carrying out integrated land management. The aim of utilizing dry land is to increase local food production and sustainability as alternative food and maintain national food security. This research was conducted using data on productivity, quantity and type of fertilizer obtained through interviews with gembili farmers and secondary data on soil types obtained from BPP Tawangsari District, Sukoharjo Regency. The results showed that grumusol and lithosol soil types had no significant effect (p > 0.05) on gembili productivity. Providing organic + inorganic fertilizer with giving organic fertilizer without a combination produced values that were not significantly different (p > 0.05). However, the average productivity results were sequentially from grumusol and lithosol (6.1 ton.ha-1 and 7.1 ton.ha-1). Meanwhile, the use of organic fertilizer is 8.06% higher compared to organic fertilizer + inorganic fertilizer. The results of the multiple regression test for organic fertilizer had a significant effect (p < 0.05) on the productivity of Dioscorea sp..

Abstract

Cabai, selain dimakan, dapat pula berfungsi sebagai tanaman hias yang mempunyai nilai keindahan. Berbagai nilai estetika yang dapat diambil antara lain adalah karakter pemendekan ruas, posisi bunga, dan warna buah muda. Pola warisan karakter itu diperlukan untuk pelaksanaan kegiatan seleksi. Informasi itu dimanfaatkan agar proses seleksi menjadi lebih efisien. Ciri pemendekan ruas pada tanaman cabai akan menjadikan bentuk tajuknya menjadi perdu, hal ini tentunya sangat menarik karena buah cabai akan terkelompok, posisi bunga dan warna buah muda juga dapat meningkatkan keindahan tanaman cabai hias. Tujuan penelitian ini adalah untuk mendapatkan informasi mengenai pola pewarisan karakter kualitatif yang berhubungan dengan pemendekan ruas, posisi bunga, dan warna buah muda sebagai kriteria seleksi dalam proses pemilihan calon cabai hias. Tanaman yang digunakan dalam penelitian ini adalah populasi tetua betina (P1) Seroja IPB yang memiliki karakter pemendekan ruas, posisi bunga tegak, dan warna buah hijau kekuningan, sedangkan tetua jantan (P2) Peter Pepper memiliki karakter buah berwarna hijau tua dan bentuk buah yang unik. Populasi dari tanaman cabai yang digunakan terdiri dari P1, P2, F1, dan F2. Analisis data dilakukan dengan uji Chi-kuadrat untuk menetapkan rasio Mendel dalam populasi F2. Temuan penelitian mengindikasikan semua karakter yang dipengaruhi oleh satu gen. Seluruh karakter diatur oleh satu gen dengan rasio 3 (dominan): 1 (resesif). Karakter pemendekan ruas, posisi bunga tegak, dan warna buah hijau tua adalah karakter yang bersifat resesif. Karakter resesif ini akan berguna sebagai kriteria seleksi karena tanaman hasil seleksi yang ditanam di generasi berikutnya tidak akan mengalami segregasi, sehingga tanaman akan lebih cepat seragam.

Abstract

The Sauyunan Women Farmers Group and the Sabilulungan Farmers Group face obstacles in meeting the demand for quality banana seeds. They usually get banana seedling propagated conventionally with the consequence that production is not optimal because of many deficiencies. Moreover, their knowledge about banana pests and diseases and their management is still lacking. These challenges were answered by providing counseling and technology transfer of acclimatization of tissue culture banana seeds based on the concept of integrated pest and disease management. The programs was attended by 23 participants who were group members and a Field Instructor Officers of Tamansari District. Participants were given counseling on the economic potential of bananas, banana tissue culture seedling, acclimatization, and types of banana pests and diseases and their management in an integrated manner. In addition, technology transfer of tissue culture banana seedling acclimatization was provided through training methods which included preparing media, planting seeds (acclimatization), handling, transplanting, as well as observation and monitoring. Thus, participants were given insight and skills in responding to the supply of quality banana seeds needed in an effort to increase their income through this program.

Abstract

Fusarium species are destructive plant pathogens responsible for severe crop losses thereby posing a critical threat to global food security. Sustainable strategies to control Fusarium-induced diseases are urgently needed due to limitations of synthetic fungicides. This study investigated the interaction of phytochemicals from potato (Solanum tuberosum), cassava (Manihot esculenta), and purple yam (Dioscorea alata) with three Fusarium proteins: LaeA, Pep2, and VeA. Protein structures were modeled and validated using stereochemical analyses, followed by molecular docking with representative metabolites, including pyrogallol, cyclogallipharaol, scopoletin, linamarin, cyanidin-3-glucoside, and peonidin-3-glucoside. Docking results showed that potato metabolites exhibited moderate binding activity, cassava metabolites displayed broader inhibitory potential, and purple yam anthocyanins demonstrated the strongest affinities (–6.7 to –7.4 kcal/mol) through multiple hydrogen bonds, hydrophobic contacts, and electrostatic interactions. Among the targets, Pep2 showed consistently stable interactions, while LaeA and VeA exhibited greater flexibility but remained responsive to anthocyanins. These findings highlight the potential of edible crop-derived phytochemicals, particularly anthocyanins and scopoletin, as eco-friendly antifungal agents. The structural basis provided here supports future experimental validation and the development of sustainable crop protection strategies.
