Abstract

This study aims to analyze the level of landslide susceptibility in the Rerer Watershed, focusing on agricultural areas dominated by mixed gardens, dryland farms, and partially open land. The parameters used include slope gradient, rainfall, land use, soil type, and geology. The analysis employed a scoring method based on Geographic Information System (GIS) techniques to produce a susceptibility zonation map. The results show that the biophysical conditions of the Rerer Watershed are dominated by moderately steep slopes (15–25%), Eutropepts Dystrandepts soil types, and weathered volcanic rocks (Qtv), combined with an annual rainfall of approximately 1,500–2,000 mm. Anthropogenic factors, particularly agricultural cultivation on sloping terrain, significantly contribute to increased vulnerability. The landslide susceptibility zonation is classified into three levels: low (43.37 ha or 14.75%), moderate (230.17 ha or 78.27%), and high (20.53 ha or 6.98%). These findings emphasize the importance of implementing soil and water conservation strategies—such as terracing, cover crops, and agroforestry systems—to mitigate landslide risks while maintaining the hydrological sustainability of the Rerer Watershed in Minahasa Regency. Keywords: landslide susceptibility, agricultural land, watershed . Abstrak. Penelitian ini bertujuan menganalisis tingkat kerawanan longsor di DAS Rerer dengan fokus pada kawasan lahan pertanian yang didominasi kebun campuran, tegalan/ladang, dan sebagian lahan terbuka. Parameter yang digunakan meliputi kemiringan lereng, curah hujan, penggunaan lahan, jenis tanah, dan geologi. Analisis dilakukan dengan metode skoring berbasis Sistem Informasi Geografis (SIG) untuk menghasilkan zonasi kerawanan. Hasil penelitian menunjukkan bahwa kondisi biofisik DAS Rerer didominasi lereng agak curam (15–25%), jenis tanah Eutropepts Dystrandepts, serta batuan vulkanik (Qtv) yang mudah lapuk, dikombinasikan dengan curah hujan tahunan sekitar 1500-2000 mm/tahun. Faktor antropogenik berupa aktivitas budidaya lahan pertanian pada lereng miring menjadi pendorong utama peningkatan kerentanan. Zonasi kerawanan longsor terbagi dalam tiga kelas, yaitu rawan rendah seluas 43,37 Ha atau sekitar 14,75%, rawan sedang seluas 230,17 Ha atau sekitar 78,27%, dan rawan tinggi seluas 20,53 atau sekitar 6,98%. Temuan ini menegaskan pentingnya penerapan strategi konservasi tanah dan air, seperti terasering, vegetasi penutup, dan sistem agroforestri, guna mitigasi risiko longsor sekaligus menjaga keberlanjutan fungsi hidrologis DAS Rerer di Kabupaten Minahasa.

Abstract

This study examines the roles of digital service quality and perceived ease of use in shaping adoption intention toward digital wealth management among millennial farmers. Drawing on a service marketing perspective and technology acceptance logic, the study also positions trust as a key mechanism that links service perceptions to adoption intention. A structured questionnaire was administered to 236 millennial farmers (aged 20–39), and the proposed model was analyzed using partial least squares structural equation modeling (PLS-SEM) with bootstrapping. The descriptive results indicate that perceived ease of use is generally high, reflecting respondents’ familiarity with smartphones, while perceptions of service quality and trust vary more substantially. The structural model shows that digital service quality strongly predicts trust (β = 0.991, p < 0.001) and that trust strongly predicts adoption intention (β = 0.810, p < 0.001). Digital service quality also has a small but significant direct effect on intention (β = 0.183, p = 0.012), indicating partial mediation. The indirect effect of digital service quality on intention through trust is large and significant (β = 0.803, p < 0.001), confirming that trust transmits most of the impact of service quality. Perceived ease of use shows statistically significant but small effects on trust and intention, suggesting usability functions primarily as a baseline enabler for digitally capable millennials. The model explains substantial variance in trust (R² = 0.979) and intention (R² = 0.981). Discriminant validity diagnostics indicate strong overlap among service quality, trust, and intention, suggesting that respondents may form a holistic evaluation of the platform; this limitation should be addressed through construct refinement in future research. Practically, the findings imply that increasing digital wealth management adoption in agricultural communities should prioritize trust-building service quality cues, including reliability, transparency, security assurance, and responsive support.

Abstract

The fall armyworm, Spodoptera frugiperda, is an invasive pest that threatens maize production and can increase dependence on synthetic insecticides, highlighting the need for locally effective biological control options. This study screened 24 local Bacillus thuringiensis isolates for insecticidal activity against third instar S. frugiperda using a maize leaf dip feeding bioassay. For initial screening, maize leaf sections were treated with 1.5 × 10⁷ spores mL⁻¹ and offered to larvae (30 larvae per isolate), with mortality recorded up to 72 h. Isolates producing at least 50 percent mortality at 72 h were advanced to pathogenicity testing. Selected isolates were evaluated at five concentrations (1.5 × 10³ to 1.5 × 10⁷ spores mL⁻¹) to estimate LC50 at 72 h, and at 1.5 × 10⁷ spores mL⁻¹ to estimate LT50; parameters were calculated by probit analysis and reported with 95 percent fiducial limits. Ten isolates met the screening criterion, and isolate ITH produced the highest mortality (93.3 percent) at 72 h. ITH also showed the greatest pathogenicity, with an LC50 of 7.5 × 10³ spores mL⁻¹ and an LT50 of 19.5 h, indicating high potency and rapid action relative to other candidates. The results demonstrate substantial variability among local Bt isolates and identify promising strains for further development. Future work should confirm isolate identity, characterize toxin profiles, optimize production and formulation, and validate efficacy and crop protection performance under semi field and field conditions for integration into maize integrated pest management.

Abstract

This study examines the effect of online visual merchandising on consumer impulse buying of online food products among Shopee users in Manado City, Indonesia, and tests the mediating role of site trust. A quantitative survey approach was employed using structured questionnaires measuring three constructs: visual merchandising, site trust, and impulse buying. Data were analyzed using regression-based mediation procedures in SPSS. The usable dataset consisted of 75 respondents. The findings indicate that online visual merchandising has a positive and significant effect on impulse buying, suggesting that attractive and informative digital product presentation (e.g., layout, images, and presentation cues) increases consumers’ tendency to make unplanned purchases. Visual merchandising also positively influences site trust. When site trust is included in the impulse buying model, it remains a significant predictor and reduces the direct effect of visual merchandising, indicating that site trust mediates the relationship between visual merchandising and impulse buying. These results highlight that effective visual merchandising not only stimulates impulsive purchase behavior directly but also indirectly by strengthening consumers’ trust in the platform. Practically, marketplace platforms and sellers should optimize visual presentation while simultaneously reinforcing trust-related signals (e.g., perceived security, reliability, and platform credibility) to encourage purchases without undermining consumer confidence. Keywords: impulse buying; Shopee; site trust; online food products; online visual merchandising

Abstract

The purpose of this study was to develop methods for inducing potato somatic embryogenesis utilizing a variety of plant growth regulator types and concentrations, both directly and indirectly. Internodal explants of the Superjhon type of potato were used in the study, which was carried out from April to July 2024 at the Tissue Culture Laboratory, Faculty of Agriculture, Sam Ratulangi University. On MS media enriched with a mixture of NAA + kinetin and BAP + 2,4-D, embryogenic callus induction was performed. While indirect somatic embryogenesis was performed utilizing embryogenic callus on MS medium with different BAP concentrations, direct somatic embryogenesis induction was performed on MS media containing zeatin, IAA, and GA₃. The best embryogenic callus with a compact and granular texture was created by combining 1.5 mg/l BAP with 0.5 mg/l 2,4-D, according to the results. In MS medium + 1 mg/l zeatin + 0.02 mg/l IAA + 0.2 mg/l GA₃, direct somatic embryogenesis demonstrated the quickest and most efficient response, with the percentage of somatic embryo development reaching 54.5% in the fourth week. In the tenth week, indirect somatic embryogenesis yielded the greatest percentage of embryos (83%) in MS medium + 7 mg/l BAP. Compared to indirect ES, direct ES is quicker, easier, and results in more consistent shoot regeneration.

Abstract

This study analyzes the structure and marketing performance of the potato supply chain in Modoinding District, North Sulawesi, Indonesia, with emphasis on product, financial, and information flows across dominant marketing channels. Primary data were collected through structured questionnaires, semi-structured interviews, direct observations, and focus group discussions with farmers and key marketing actors. Supply chain mapping was used to identify actors and channel pathways, while marketing performance was evaluated using marketing margins, marketing costs, marketing profits, and farmer share. The mapping results indicate three dominant channels: (1) local marketing to Modoinding and Kotamobagu traditional markets, (2) distribution to Manado traditional markets, and (3) inter-island distribution via port-based traders/offtakers. Farm-gate price was IDR 15,000/kg across channels, while terminal prices increased with channel length: IDR 17,000–17,500/kg (Modoinding local), IDR 18,500/kg (Kotamobagu), IDR 21,000/kg (Manado), and IDR 25,000/kg (inter-island). Consequently, total marketing margins rose from IDR 2,000–2,500/kg in the shortest channel to IDR 10,000/kg in the inter-island channel, and farmer share declined from approximately 85.7–88.2% (local Modoinding) to 60.0% (inter-island). Transport and shipping-related activities were the main cost drivers in longer channels. Overall, improving postharvest handling, logistics coordination, and market information feedback to farmers is critical to reduce losses and enhancing upstream value capture.

Abstract

Eco-enzyme has been promoted as a low-cost bioactivator for converting organic residues into useful soil amendments, but comparative agronomic evidence across different waste substrates remains limited. This study evaluated eco-enzyme–assisted organic fertilizers prepared from several locally available organic wastes and assessed their effects on chili pepper (Capsicum annuum L.) growth and yield in Kakaskasen, Tomohon City, North Sulawesi, Indonesia, from April to October 2025. A pot experiment was arranged in a completely randomized design with six treatments and four replications (24 experimental units). Eco-enzyme was produced by fermenting fruit peels, sugar, and water (3:1:10) for three months. Organic fertilizers were prepared using eco-enzyme alone or eco-enzyme combined with vegetable waste, fruit waste, market waste, chicken-manure waste, or household organic waste, and were incorporated into the pot medium one week before transplanting at an equivalent rate of 20 t ha⁻¹. Plant height, fruit number per plant, and fresh fruit weight per plant were measured at 100 days after transplanting and analyzed using analysis of variance followed by the least significant difference test at 5%. Organic-waste substrate significantly affected all measured variables. The eco-enzyme + market-waste formulation produced the tallest plants (133.37 cm), the highest fruit number (89.50 fruits plant⁻¹), and the highest mean fresh fruit weight (225.25 g plant⁻¹), markedly exceeding eco-enzyme alone (69.12 cm; 36.75 fruits plant⁻¹; 78.75 g plant⁻¹). Overall, eco-enzyme–activated market-waste fertilizer was the most effective formulation for improving chili growth and yield under the conditions of this pot experiment.
