Agricultural practices that take local wisdom into account can provide significant benefits to the environment and society. Local wisdom plays a crucial role in sustainable agricultural practices. Time-tested knowledge and practices can provide solutions to the challenges faced by modern farmers, particularly in the context of climate change and environmental degradation. However, despite extensive research, a significant research gap remains, specifically how local wisdom in the Tumbang Datu Valley can be integrated into broader agricultural policies. The research used was descriptive with a qualitative approach. Qualitative research aims to understand social phenomena from the perspective of participants. Initial informants were selected purposively, selecting informants deemed to have extensive knowledge of the conditions in the village under study, using a snowball sampling technique. The first step was to identify key informants, who in this study consisted of 16 traditional leaders and farmers familiar with the culture in Lembang Tumbang Datu and directly involved in the practice. The local wisdom in the rice farming process, from pre-planting, planting, maintenance, to harvesting and post-harvest, is implemented based on ancestral heritage in line with environmental conservation. Farmers demonstrate their concern for nature through natural soil cultivation, selection of superior seeds, use of organic fertilizers, and implementation of efficient planting and irrigation systems. The application of Integrated Pest Management (IPM) and post-harvest technology demonstrates the farmers' ability to adapt to innovation while maintaining local wisdom. Overall, the rice farming system in Lembang Tumbang Datu demonstrates the synergy between tradition and modernity, supporting food security while preserving cultural heritage.

Dependence on chemical fertilizers has caused a decline in soil quality, groundwater contamination, and rising agricultural production costs due to unstable fertilizer prices. In recent years, frequent fertilizer crises have revealed the fragility of reliance on inorganic fertilizers within the national agricultural system. Hence, a transformation toward environmentally friendly and sustainable agriculture is urgently required. This study employed a scoring technique to analyze field observation data, which were narrated based on the written methodology. Respondents’ answers were categorized and classified according to their assumptions or opinions, with scores determined using a Likert scale. The Likert scale measures attitudes, opinions, and perceptions of individuals or groups regarding specific social phenomena. The results showed that key driving factors—such as affordable fertilizer prices, support from agricultural extension workers, and social encouragement from the community—achieved scores above 82%. This finding indicates that external conditions are quite favorable for promoting the use of organic fertilizers. However, major challenges remain, including the limited availability of organic fertilizers in the field and farmers’ long-standing dependency on chemical fertilizers. To address these challenges, it is essential to enhance the market availability of liquid organic fertilizers (POC) through collaboration between producers and farmer groups. Continuous technical assistance should be provided, including demonstration plots that display tangible improvements in rice yields using POC. Furthermore, government support in the form of targeted subsidies or special incentives for farmers transitioning to organic fertilizers is vital, while strengthening the role of farmer groups and agricultural extension workers as catalysts for the adoption of environmentally friendly innovations.

The use of plastic as planting containers remains a serious environmental issue due to its non-biodegradable nature, which can contaminate soil and water. One solution is to utilize rice straw waste as a raw material for biodegradable pots. This innovation can reduce dependence on plastic pots while providing ecological and economic benefits. Rice straw-based pots offer several advantages, including easy decomposition in soil, enhancing soil fertility, and reducing pollution caused by straw burning. This study aims to utilize rice straw waste to produce environmentally friendly biodegradable pots as an alternative to plastic containers. The method employed is Participatory Action Research (PAR), emphasizing collaboration between students and teachers through hands-on learning. The activities include socialization, practical training on making rice straw pots, participatory evaluation, and the use of the pots as planting media. The results showed that 100% of participants successfully produced high-quality rice straw pots, with positive responses reflected in high satisfaction and increased understanding of recycling concepts. The rice straw pots decompose within 2–3 months, add organic matter to the soil, and create opportunities for a circular economy. The main challenge identified is the relatively short durability of the pots, requiring innovations using natural adhesives or material combinations to enhance resilience. These findings reinforce the potential of rice straw as a solution for agricultural waste management and community empowerment toward sustainable agriculture.

Intestinal parasitic infections caused by non-Soil Transmitted Helminths (non-STH), particularly Enterobius vermicularis, remain a public health problem in developing countries, including Indonesia. Transmission does not require soil as a medium but occurs through direct contact, autoinfection, or unclean household environments. In children, infection may cause perianal itching, sleep disturbances, loss of appetite, and secondary infections due to scratching, which can affect nutritional status, sleep quality, and overall growth and development. This study was conducted in Kupang City, an endemic area of helminthiasis, to determine the prevalence and risk factors of E. vermicularis infection among children aged 1–5 years. A cross-sectional design with total sampling was applied to 30 children living in RT 008/RW 003, Penfui Timur Village, Kupang Tengah District, from February to May 2025. Risk factor data were collected using structured questionnaires covering personal hygiene, environmental sanitation, socioeconomic status, and parental education. Infection was identified using the scotch tape technique and microscopic examination. The results showed a prevalence of 7% (2 out of 30 children), mainly among boys aged ≥4 years, with poor personal hygiene, inadequate sanitation, low economic status, and parental education at elementary school level or below. In conclusion, enterobiasis in children is influenced by a combination of behavioral, environmental, and socioeconomic factors. Prevention should not rely solely on mass deworming programs but also require continuous health education for parents, improved hygiene practices, and household sanitation.

Organic agriculture plays a vital role in Indonesia’s agricultural development, with a key challenge being how to boost productivity efficiently and sustainably. Liquid Organic Fertilizer (LOF) derived from natural materials provides an eco-friendly option to improve soil fertility and crop yields. Bamboo shoots (Bambusa spp.), rich in organic carbon and gibberellin, present strong potential as LOF raw material to support plant growth. This study evaluated the effect of bamboo shoot-based LOF on the growth and yield of white radish (Raphanus sativus). The research was conducted from May to August 2025 in Kalolok, Batupapan Village, Tana Toraja Regency, South Sulawesi, at an altitude of 775 m. LOF was produced by fermenting 200 kg of ground bamboo shoots with 4 kg palm sugar, 1 liter EM4, and 200 liters water for 14 days. Treatments consisted of 0, 100, 200, and 300 ml per liter of water, applied twice at two-week intervals starting 14 days after planting. Using a randomized block design with four treatments and three replications, variables observed included plant height, leaf number, tuber size, and yield. Results showed that 300 ml/liter LOF gave the best outcomes: tallest plants (27 cm), most leaves (15.89), largest tubers (29.37 cm length; 6.06 cm diameter), and highest weight (731 g/plant; 6936.67 g/plot). These effects are linked to balanced nutrients (N, P, K, Mg, Ca) enhancing vegetative growth and tuber development. Thus, bamboo shoot-based LOF at 300 ml/liter is recommended as an effective organic fertilizer for white radish.

This research discusses the effect of coconut dregs compost (Cocos nucifera L.) on the growth and yield of tomato plants (Solanum lycopersicum L.) cultivated using polybag media. This research is motivated by the importance of utilizing organic waste, especially coconut dregs, which has not been utilized optimally. Coconut dregs contain organic materials and nutrients that have the potential to increase soil fertility and improve the structure of the planting medium, so it is expected to support the vegetative and generative growth of tomato plants. The research design used was a Randomized Block Design (RBD) with six treatments and four replications. The treatments given were different doses of coconut dregs compost, namely P0 (control without compost), P1 (100 g/polybag), P2 (200 g/polybag), P3 (300 g/polybag), P4 (400 g/polybag), and P5 (500 g/polybag). The parameters observed included plant height, stem diameter, fresh weight, number of fruits per plant, root length, and estimated yield per hectare. The results showed that the application of coconut pulp compost significantly affected several growth parameters, such as plant height, stem diameter, and fresh weight. However, no significant effect was found on the number of fruits per plant or yield per hectare. The most prominent response was seen in the root length parameter, which showed a significant increase with increasing compost dosage. From the observations, the best treatment was at a dosage of 300 g/polybag (P3), which provided an optimal balance between vegetative growth and potential generative yield.

The land of the former Pit B limestone mine of PT Semen Baturaja has failed to plant and grow dwarf plants at several locations due to low nutrient content, such as Nitrogen, Phosphorus, Potassium, Soil PH, C-Organic, and cation exchange capacity (KTK). This condition causes the plant not to grow optimally. This study aims to determine the effect of the application of Rhizobium sp bacteria on the growth of Sengon plants (Falcataria moluccana) using polybag media on the land. The method used was an experiment with the treatment of giving Rhizobium sp in various doses. The results of the study showed that the administration of Rhizobium sp had a real effect on increasing the growth of sengon plants. Based on laboratory observations and analysis, there is a change in soil pH from slightly alkaline to neutral after treatment. The C-Organic content increased from medium to very high, while the Nitrogen content rose from medium to high. The elements of Phosphorus, Potassium, and KTK have also increased significantly and are classified as very high. The best treatment is obtained at a dose of 30 grams of Rhizobium sp, which gives optimal results on an increase in plant height and root length. These findings suggest that the application of Rhizobium sp can be an effective biotechnology alternative in post-mining land rehabilitation, particularly in improving soil fertility and forestry crop productivity. This research contributes to environmental management and the use of microorganisms in the restoration of degraded ecosystems.

The use of alternative culture media is crucial, especially in regions with limited access to commercial media such as Nutrient Agar or Potato Dextrose Agar, which are relatively expensive. Cassava, a tropical tuber rich in starch and widely available in Indonesia, offers significant promise as a natural substrate for microbial growth. Microbial isolation was performed using a serial dilution method on soil samples collected from an organic garden. The media was prepared from cassava juice mixed with agar and glucose, sterilized, and poured into petri dishes. After inoculation, microbes were incubated for seven days at room temperature. Colony morphology was observed macroscopically, and Gram staining was used to identify bacterial characteristics. The results revealed that cassava extract media effectively supported the growth of diverse microbial colonies, varying in shape, color, and edge structure. Most isolates were identified as Gram-positive, with rod and coccus forms. The presence of pigmented colonies indicates the potential of certain isolates to produce bioactive compounds. In conclusion, cassava extract-based media is a viable alternative for soil microbiology studies. It is not only cost-effective but also facilitates the exploration of local microbial diversity with potential applications in biotechnology, including bioremediation and enzyme production. This approach encourages the use of indigenous resources in scientific research, promoting sustainability and accessibility in microbiological practices.
