Abstract

Jatinangor Inceptisols are formed from volcanic material with a high concentration of iron oxide and a low concentration of phosphorus (P), which leads to high rates of P fixation and low P fertilization efficiency. The situation is exacerbated by intensive agricultural practices. This research was conducted to assess the effect of humic acid derived from low rank coal (AHL) as a soil conditioner in enhancing P availability and chili response in P-deficient Inceptisols. The experiment was conducted in the greenhouse of the Soil Chemistry and Plant Nutrition Laboratory at Universitas Padjadjaran. AHL treatments were combined with various doses of SP-36 fertilizer to evaluate their direct and indirect effects on soil chemical properties, phosphate-solubilizing bacteria (PSB) populations, P uptake, and plant responses. The results showed that AHL application did not cause metal toxicity symptoms and significantly increased potential P, available P, cation exchange capacity (CEC), and total PSB populations. The best results were obtained with a combination of AHL at 30 kg ha?¹ and SP-36 at 125 kg ha?¹, which optimally enhanced P dynamics and chili yields. AHL was proven to reduce the need for inorganic P fertilizer by up to 50% without compromising chili yield or quality. These findings indicate that AHL has great potential to be developed as a locally sourced soil conditioner to support sustainable agriculture and the use of more environmentally friendly low-rank coal.

Abstract

Bananas are one of Indonesia’s most important horticultural crops, valued for their adaptability and economic potential. Among them, the Roid banana (ABB) (Musa spp.) stands out as a local variety native to West Java-Indonesia, particularly the Jatigede District, Sumedang Regency where it thrives naturally without agronomic inputs. Known for its resistance to pests and diseases, long shelf life, and strong fruit attachment that reduces post-harvest losses, the Roid banana remains underutilized and understudied. Despite its advantages, research on its genetic diversity is limited, highlighting the need for characterization as a foundation for conservation and breeding. This study, conducted from October to December 2023 in the Jatigede District, aimed to analyze the distribution patterns and genetic diversity of Roid bananas. Characterization used a survey method and purposive sampling in situ. Results revealed two primary clusters dominated by accessions from Ciranggem and Jemah Villages. Key traits supported clusters were peduncle curvature, bunch length and density, number of fruit hands, male flower attitude, apex shape, skin color, plant height, and the presence of hermaphrodite flowers. The genetic diversity based on Euclidean distances was 0.47 to 11.92. The Index of Cultural Significance value was 105, implying a very high level of utilization diversity. These findings highlight the genetic richness and cultural importance of Roid bananas, offering valuable insights for future conservation and breeding programs.

Abstract

The effectiveness of arbuscular mycorrhizal fungi (AMF) as a biofertilizer in enhancing plant growth is influenced by environmental factors that can inhibit germination and reduce spore viability. Encapsulation using alginate as a coating material, combined with audiosonic stimulation, may improve spore protection and physiological activity. This study was conducted from October 2025 to February 2026 at the Soil Biology Laboratory, Department of Soil Science and Land Resources, Faculty of Agriculture, Universitas Padjadjaran, to evaluate the interaction between alginate concentration and audiosonic treatment on AMF spore germination and viability. The experiment was conducted using a Completely Randomized Design (CRD) with six treatments and three replicates. Alginate concentrations consisted of 1%, 2%, and 3%, while the audiosonic treatments included no audiosonic exposure and exposure to 8 kHz at a duration of 8 hours per day. The results showed a significant interaction between alginate concentration and audiosonic treatment on AMF viability. The 2% alginate concentration resulted in the greatest spore viability.

Abstract

Mycorrhizal biofertilizer is increasingly recognized as an eco-friendly soil amendment capable of improving nutrient uptake, plant resilience, and overall crop productivity. However, knowledge and utilization of mycorrhiza among smallholder farmers—especially housewives involved in home-scale farming—remain limited in many rural areas in Indonesia. This community service program aimed to enhance the knowledge, skills, and willingness of 20 housewives in Pamulihan Village, Tanjungsari District, Sumedang Regency, regarding the use of mycorrhizal biofertilizer for edamame cultivation. The training employed participatory learning methods, including lectures, demonstrations, hands-on practice, and discussions. Pre- and post-training assessments were conducted to evaluate changes in participants' understanding and readiness to adopt the technology. Results showed significant improvement across all indicators. Knowledge of the term “mycorrhiza” increased from 0% to 100%, ability to apply mycorrhiza increased from 0% to 100%, understanding of its benefits rose from 0% to 100%, and willingness to use mycorrhiza increased from 12.5% to 100%. Additionally, 68.75% of participants reported direct experience using mycorrhiza after the program, compared to none before. These results indicate that hands-on field-based training is highly effective in empowering rural communities—especially women—to adopt sustainable agricultural technologies. The program contributes to improved soil health, increased productivity potential for edamame, and enhanced environmental literacy in the village. The findings support the need for continued capacity building and community-based demonstrations to promote long-term adoption of biofertilizers.
