Abstract

Perkebunan teh Pangalengan, Kabupaten Bandung, memiliki kondisi lingkungan yang mendukung jamur patogen serangga (JPS) sebagai agens pengendali hayati (APH). Penelitian ini bertujuan untuk mengisolasi JPS dari rizosfer perkebunan teh dataran tinggi serta mengetahui persistensinya setelah dipaparkan sinar UV. Isolasi JPS dilakukan dengan metode umpan serangga menggunakan Tenebrio molitor dan dilanjutkan dengan seleksi berdasarkan kerapatan dan viabilitas konidia. Uji persistensi dilakukan terhadap konidia yang dipaparkan sinar UV pada 254 nm selama 0, 15, 30, 45, dan 60 menit dengan lima kali ulangan. Kerapatan dan viabilitas konidia digunakan untuk menghitung kelangsungan hidup. Berdasarkan hasil penelitian, terdapat 7 isolat jamur yang diperoleh dari rizosfer perkebunan teh dataran tinggi Pangalengan yang terdiri dari 3 genus, yaitu genus Fusarium sebanyak 5 isolat, genus Penicillium sebanyak 1 isolat, dan genus Beauveria sebanyak 1 isolat. Pemaparan sinar UV selama 60 menit pada isolat Penicillium sp. Pg-P1 mampu menurunkan kerapatan konidia sebesar 73,43% dan viabilitas konidia sebesar 60,71%. Hal tersebut menunjukkan bahwa persistensi Penicillium sp. Pg-P1 menurun seiring dengan meningkatnya durasi paparan sinar UV.

Abstract

Rice field bunds function as a reservoir of biodiversity, one of which is entomopathogenic fungi (EPF), which plays a role in controlling insect populations and increasing plant resistance. This study aimed to explore the interaction between organic matter content, soil pH, and EPF diversity in rice fields from Mulyoagung Subdistrict, Malang Regency. EPF was isolated using the insect bait method, followed by pathogenicity testing on Tenebrio molitor larvae. The Shannon-Wiener index (H'), evenness (E), and dominance (C) were used to assess the diversity of EPF on rice field bunds. Spearman correlation analysis was conducted to test the relationship between organic matter content, soil pH, and EPF diversity. Based on the results of the study, three genera of EPF were found in the rice fields, namely Beauveria, Fusarium, and Metarhizium. The presence of EPF is influenced by understory plants and the amount of organic matter in the soil. Therefore, preserving rice field bunds is very important to maintain the EPF population.

Abstract

Two spotted mite (TSM) Tetranychus sp. is often used as host for predator mite Phytoseiidae mass rearing. To obtain high population of TSM in short time, it must be reared in host plants that support optimum growth and development. The objective of this research was to observe population development of TSM on legumes such as mungbean (Vigna angularis), adzukibean (V. radiata), snapbean (Phaseolus vulgaris) and soybean (Glycine max) (wilis and anjasmoro cultivars) and to compare the growth of the legumes based on their fresh leaf weight and leaf area, and cost seed index (CSI). The results showed that mungbean was suitable host plant for TSM mass rearing because its population on this legume was the highest. Mungbean’s fresh leaf weight and leaf area was the highest. If TSM is reared in plant in greenhouse, CSI will become one of criteria for determining the host plant. Although CSI of mungbean was low because TSM population that was reared on it is the highest, the mungbean was the most suitable host plant for TSM growth and development. Another host plant that was suitable for TSM reared was adzukibean.Keywords: legumes, mass rearing, Tetranychus uritcae

Abstract

This community service program aimed to analyze the level of knowledge and identify strategies for introducing organic farming and natural dye production technologies for ikat weaving among the Dayak community in Ensaid Panjang Village, Sintang, West Kalimantan. The program employed an action research method with a problem-based learning approach. The activities began with a community needs assessment, followed by the delivery of materials and information through lectures, simulations, demonstrations, and training sessions. A total of 52 participants took part in the program. Among them, several informants were selected based on their knowledge and expertise. The key informants included the head of Ensaid Panjang Village, the Betang customary elders, and representatives from the Ensaid Panjang community. The results showed that three leading indicators demonstrated significant improvement in participants’ understanding. These included enhanced community skills in producing natural dyes from local plants for ikat weaving, the ability to process organic fertilizers from household waste, garbage, and animal manure, as well as the strengthening of institutional roles that support the production and marketing of woven fabrics. The substantial increase in understanding indicated that this program successfully improved participants’ knowledge and skills. Overall, the average increase in community understanding and achievement was 11%, with a notable 51% increase in knowledge of composting specifically.

Abstract

The aims of the research were to Identify the species of Anaphalis found in Poncokusumo District, profiling distribution of Anaphalis in Poncokusumo Distrit, and describing habitat of Anaphalis in Poncokusumo District. The benefit of this research is the availability of baseline data as a reference for enforcement of conservation measures for Anaphalis species found in Poncokusumo. Conservation steps that can be taken include socialization of the local community, habitat protection and population monitoring. The field survey was carried out in October-December 2020 by measuring several plots in the area found by Anaphalis. Each site was analyzed for vegetation by measuring the density, frequency and cover of plants. Plant species included in the quadratic plot of 1x1 m2 were identified. In addition, microclimate factors were recorded, such as temperature, humidity and light intensity as well as altitude, coordinate points, soil type and land slope. Interviews with the local people, We interviewed informant especially was key person around we found Anaphalis habitat. We conducted a face-to-face semistructured questionnaire and asked our informants to ask about the distribution, uses and functions, and community conservation efforts of Anaphalis. Data analysis, Vegetation analysis to know composition of plant species inside quadrates for determining diversity index, important value index, dominance and everlasting of plant. Abiotic factors that have been measured are shown in tabular form as a comparison between distribution locations. Information from interview with local person was interpreted qualitatively descriptive. Some of the conservation opportunities in the strategy are policy support for biological conservation and the ecotourism movement, threat aspects such as reduced control of land functions in mass tourism. In this study, the SWOT analysis provides recommendations on significant strategies that come from a combination of strengths and optimizing opportunities, and reducing weaknesses and optimizing opportunities so that strengths reduce threats and manage risks.

Abstract

The Mina Makmur Jaya Floating Net Cage (KJA) Group in Gampingan is a community group engaged in the breeding of Nile tilapia (Oreochromis niloticus) using the puddle system method, located in Gampingan Village, Pagak District, Malang Regency. The main problem faced in this business is the slow growth of fish fry, which results in suboptimal seed production. This condition is caused by several factors: water quality that is highly dependent on weather conditions, inappropriate breeding techniques, and inadequate nutrition or feed. The proposed solutions include conducting socialization activities and preparing a water quality management module based on Adaptive Water Management, providing water quality measuring instruments, organizing training and SOP development for seed breeding and packaging techniques, and conducting socialization on feed management for tilapia hatchery. The results of these activities showed an increase in partners’ technical skills, business management efficiency, and seed quality. In addition, outputs were produced in the form of SOPs, training modules, activity documentation, and new skills that help improve tilapia fry productivity, reduce operational costs, and expand distribution reach. Thus, this program contributes to strengthening food security, increasing economic value, and ensuring the sustainability of tilapia breeding enterprises at the local level.
