Abstract

Leaf blight that attacks teak (Tectona grandis L.f.) can reduce the plant's productivity. Leaf blight control can be done through dark septate endophyte (DSE). This study aims to test the ability of DSE GS2 and DSE TM fungi to inhibit the growth of pathogen colonies that cause leaf blight in vitro. Antagonistic tests of DSE against pathogen that cause leaf blight were carried out through a modified double culture test. The results of the antagonistic test showed that DSE GS2 and DSE TM could inhibit the growth of pathogens. The best inhibition results were demonstrated in the second double culture test after DSE was grown for seven days because DSE could grow stably and produce metabolite compounds. DSE TM had the best inhibition compared to DSE GS2. The mechanism of DSE inhibition against pathogens occurs through physical contact and the production of metabolite compounds characterized by the inhibition zone around the DSE. Keywords: Biocontrol, colony, Preventive, Rhizoctonia sp.

Abstract

The rice productivity in Gondel Village, Kedungtuban District, Blora Regency, Central Java, has declined. Factors such as attacks by plant pests and diseases (OPT), climate change (DPI) impact, and decreasing soil quality are the leading causes of crop failure. This training aims to enhance the understanding and skills of Gondel Village farmers in making biofertilizers and introducing environmentally friendly pest and disease control methods. The activity involved 40 farmers from 8 farmer groups (Gemah Ripah, Margo Mulyo, Ngudi Makmur, Sido Dadi, Sido Makmur, Tambah Makmur, Tambah Rizki, and Sri Mulyo), with each group represented by five farmers. The training methods included analysis of soil chemicals, socialization, practical propagation of Trichoderma sp. on rice media, and biofertilizer production. Pre-test and post-tests were conducted to assess the improvement in farmers' knowledge. Trichoderma biofertilizer was formulated using carriers such as a) Manure and b) Compost, zeolite, and humic acid. The results of the soil chemical properties analysis showed that farmers' use of chemical fertilizers was very intensive, resulting in very high levels of phosphorus (P) and calcium (Ca) and high levels of potassium (K), magnesium (Mg), and cation exchange capacity (KTK). Evaluation results indicated that the training significantly improved the farmers' knowledge of biofertilizer production in theory and practice. However, some farmers still need further guidance on the propagation of the biological agent Trichoderma sp.

Abstract

Sengon (Paraserianthes falcataria (L.) Nielsen) is a fast-growing tree species, and its wood is readily available because it has been widely cultivated in Indonesia. Efforts to propagate sengon plants are carried out through breeding activities in the nursery. The study aimed to identify the fungus that causes leaf disease on sengon plants and calculate the extent and intensity of attacks by the fungus that causes leaf disease on sengon in the Dramaga Bogor Permanent Nursery. This research consisted of pathogenicity test activities, including field observations, Koch's postulates, and the identification of fungal species. The study used a Completely Randomized Factorial Design. The disease symptoms found around 2 months of sengon leaves at the observation site were leaf fall, leaf spot, and leaf blight. The identified fungus that caused leaf fall was Rhizoctonia sp. The fungus that caused leaf spots was Colletotrichum sp., and the fungus that caused leaf blight was Fusarium sp. Fusarium sp. resulted in the highest percentage of attacks, with a disease incidence of 67% and a disease severity of 57%. Keywords: characteristics, identification, Koch`s postulates, morphology

Abstract

Cibunian Village, Pamijahan District, Bogor Regency, has great potential as an ecotourism destination. One of the unique tourist destinations currently being developed is the Bogor Waqf Forest. However, this village is highly prone to landslides, requiring collaboration from various parties to address the issue. One of the potential collaborations is with the youth, through the Cibunian Village Youth Organization (Karang Taruna). This community service program aims to improve the knowledge and skills of the Cibunian Village Youth Organization (Karang Taruna) administrators regarding zakat waqf literacy, waqf-based forests, Waqf Forest applications, and carbon accounting. The entire series of activities was held in September 2024, in the form of four training sessions. The first two sessions are lectures by resource persons on zakat waqf literacy and waqf-based forests, and the final two sessions are practical carbon accounting for trees in the Bogor Waqf Forest and the use of the Waqf Forest application. The data collection method was through questionnaires before and after training, analyzed descriptively, as well as an assessment of direct practical activities during the training session. Based on observations, it can be concluded that the Cibunian Village Youth Organization (Karang Taruna) has improved their understanding of the basic concepts of zakat and waqf, as well as their ability to conduct surveys, operate the Waqf Forest application, perform carbon calculations, and manage waqf-based forests. This can enhance the sense of ownership and role of local communities in protecting the environment, preventing disasters, and optimizing village potential through waqf-based forests.
