Abstract

Abstrak               Tantangan pertanian ke depan adalah peningkatan produksi pertanian, kelestarian lingkungan dan kesehatan masyarakat sebagai akibat meningkatnya jumlah penduduk dan kesadaran masyarakat akan pengaruh negatif yang ditimbulkan oleh penggunaan pupuk anorganik dan pestisida sintetik/kimia (anorganik).  Sistem pertanian organik merupakan salah satu solusi yang diajukan untuk diterapkan pada sistem pertanian di masa yang akan datang.  Sistem pertanian organik adalah sistem budidaya pertanian yang mengandalkan bahan-bahan alami tanpa menggunakan bahan kimia/sintesis (anorganik).  Pemanfaatan pupuk organik dan pestisida nabati dalam usaha pertanian akan mengurangi resiko pencemaran lingkungan, meningkatkan efisiensi pemupukan, serta menekan pengaruh negatif dari penggunaan pupuk anorganik dan pestisida sintesik/kimia (anorganik).  Prinsip dalam sistem pertanian organik adalah adanya keseimbangan siklus hara dan kesuburan tanah serta pengendalian hama dan penyakit secara terpadu.  Untuk meningkatkan kesuburan tanah dan memenuhi kebutuhan pupuk organik di dalam menjaga keseimbangan siklus hara, serta mengurangi penggunaan pestisida nabati, peran legum seperti bengkuang (Pachyrrhizuz erosus L.) perlu dikaji lebih mendalam. Tanaman bengkuang sangat potensial dalam mendukung diterapkannya sistem pertanian organik karena; biomassa yang banyak dan mengandung nitrogen yang tinggi (3.42% - 3.51%), kemampuan hidup yang sangat luas di berbagai kondisi lahan karena bersimbiosis dengan bakteri Rhizobium dan Bradyrhizobium dalam menambat nitrogen (N2) udara dan bersimbiosis dengan cendawan mikoriza (AMF) yang dapat membantu penyerapan unsur hara terutama fosfor.  Selain itu, kecuali umbi, bagian tanaman lainnya terutama pada biji bengkuang mengandung metabolit sekunder seperti rotenon yang bersifat insektisida.  Dengan demikian maka bengkuang ini dapat dimanfaatkan sebagai bahan pupuk organik dan sebagai insektisida nabati dalam mendukung sistem pertanian organik. Kata Kunci: bengkuang(Pachyrrhizuz erosus L.), legum, rotenon, sistem pertanian organik Abstract                The challenge of agriculture in the future is to increase agricultural production, environmental sustainability and public health as a result of increasing population and public awareness of the negative effects caused by the use of inorganic fertilizers and chemical/ synthetic pesticides. Organic farming system is one of the solutions proposed to be applied to agricultural systems in the future. Organic farming system is an agricultural cultivation system that relies on natural materials without using synthetic/chemicals (inorganic). Utilization of organic fertilizers and pesticides in agricultural businesses will reduce the risk of environmental pollution, improve fertilization efficiency, and reduce the negative effects of the use of inorganic fertilizers and chemical/synthetic pesticides. The principle in organic farming systems is the balance of nutrient cycling and soil fertility and integrated pest and disease control. To improve soil fertility and meet the needs of organic fertilizer in maintaining the balance of nutrient cycles, and reduce the use of synthetic chemical pesticides, the role of legumes such as yam bean (Pachyrrhizuz erosus L.) needs to be studied more deeply. Yam bean plants are very potential in supporting the implementation of organic farming systems because; a lot of high and nitrogen containing biomass (3.42% - 3.51%), a very broad life ability in various land conditions because it is symbiotic with Rhizobium and Bradyrhizobium bacteria in fixing nitrogen (N2) air and symbiosis with mycorrhizal fungi (AMF) which can help absorption of nutrients, especially phosphorus. Especially in jicama seeds contain secondary metabolites such as rotenone which are insecticides. Thus, this yam bean can be used as an organic fertilizer and as a organic/vegetable insecticide in supporting organic farming systems. Keywords: Yam bean (Pachyrrhizuz erosus L.), legumes, rotenon, organic farming systems

Abstract

Urban expansion has led to a significant decline in agricultural land and green open spaces. Urban farming emerges as an alternative approach by optimizing and managing limited open areas among urban structures. Urban farming initiatives conducted by the Flamboyan Dasawisma Group in Padaleu Village, Kambu District, Kendari City, provide green vegetables as a nutritional source, enhance environmental quality, and support efforts to mitigate the impacts of global warming. This Community Service Program (PKM) aims to improve community knowledge and skills while increasing awareness of the importance of utilizing household yard spaces to achieve family food security and environmental sustainability through urban farming practices. The program was implemented through educational outreach to community groups about the benefits and application of urban farming, followed by hands-on mentoring in establishing an urban farming garden as a demonstration model for the Padaleu Village community. The findings reveal a positive response from members of the Flamboyan Dasawisma Group, along with strong expectations for the program's continued support. This community service initiative is anticipated to provide tangible benefits to the local community, particularly the Flamboyan Dasawisma Group, by reducing household expenditures. Furthermore, community members demonstrated high enthusiasm for cultivating vegetables using the urban farming system.

Abstract

The problems of members of the Manggarai Women’s Farmers Group in Padaleu Village, Kambu District, Kendari City are (1) so far no party has socialized the adverse effects of using inorganic fertilizers and the trend of public awareness of consuming organic food ingredients so that farmers are directed to use organic fertilizers. (2) the target audience has not received an explanation about LOF, including the basic ingredients, benefits, how to make it, and its application to vegetable plants in the yard. This activity aims to (1) Improve the knowledge of Women Farmer Group members about the adverse effects of using inorganic fertilizers, (2) Provide understanding to the community about using rice washing water as a basic ingredient for LOF, and (3) Increase knowledge about LOF methods, materials and applications. This activity begins with direct observation in the field to discover the problem and determine the method used in the activity—next, socialization with members of the Women’s Farmers Group. The method used is a combination of counseling and technical guidance as follows: (1) Socialization through delivering materials, lectures and discussions regarding the negative impacts of inorganic fertilizers used on humans, soil and the environment; the importance/benefits of LOF and what basic ingredients can be used in making LOF; and benefits of LOF, and (2) Making liquid organic fertilizer based on rice washing water with the help of EM-4 to be applied to organic vegetable plants in the yard. LOF is fermented for 2 weeks, resulting in a 60 L volume. Applying LOF based on rice washing water can increase the growth and yield of vegetable plants in the yard.

Abstract

Agricultural Innovation in the green revolution contains high ecological risk, so that eco-technology innovation is needed for the sustainability of agricultural productivity. Unfortunately, not all farmers know about of this innovation, including members of the Nanga-Nanga Makmur Farmers Group around the Kendari City Botanical Gardens. This Community Partnership Program aimed to: (i) increase the knowledge and skills of target farmers regarding the management of abundant organic waste around farmers' fields to be used as non-microbial biofertilizer products; and (ii) provide knowledge to target farmers about conducting soil quality testing as a reference for farmers to determine the dose of non-microbial biofertilizer on managed agricultural land by members of the farmer groups. The method applied to achieve this goal is to do incidental counseling through face-to-face activities, training activities through mentoring in plot demonstration actions. Data on the increasing knowledge and skills of farmers were recorded through photos during mentoring and pilot demonstrations and analyzed descriptively. The results of these activities have increased the knowledge and skills of farmers in evaluating soil fertility using KIT for soil analysis, and determining the need for organic matter and fertilizers. Partner farmers have been able and skilled to produce biochar, compost tea, and compost as non-microbial biofertilizer by utilizing liquid organic waste and organic solid waste. Farmers can to manage soil quality and plant health through the application of non-microbial biofertilizer to soil and plants. Farmers also have insight into pest/disease control through an eco-technology approach.

Abstract. Kilowasid LMH, Al’adlin, Alam S, Rakian TC, Rahni NM, Adawiyah R. 2026. Soil invertebrates in an Ultisol soybean agroecosystem amended with urea-enriched cogongrass biochar prepared with Sargassum extract. Biodiversitas 27 (1): d270116. https://doi.org/10.13057/biodiv/d270116. Soil invertebrates are widely used as bioindicators to assess changes in ecological functioning under different management practices. However, information on the influence of enriched biochar amendments on the community of invertebrates in tropical Ultisol remains limited, particularly in the context of reducing dependency on synthetic fertilizer through organic-based management. Therefore, this study aimed to evaluate the interactive effects of cogongrass (Imperata cylindrica) biochar doses and urea concentrations dissolved in Sargassum seaweed extract on the abundance and diversity of soil invertebrates in an Ultisol-based soybean agroecosystem. A split-plot experiment was conducted using three biochar doses (0, 5, and 10 t ha⁻¹) and four urea solution concentrations (0, 5, 10, and 20%) as main plots and subplots, respectively. Soil-surface invertebrates were collected using pitfall traps, while soil-living invertebrates were sampled through hand-sorting and monolith methods, and identified at the family level. The results showed that biochar and urea amendments significantly restructured the community of soil invertebrates, with contrasting responses between soil-surface and soil-living groups. Biochar dose primarily influenced surface-active invertebrates, and urea concentration affected specific soil-living taxa, with interaction effects observed for selected functional groups. Higher biochar doses increased community diversity, as reflected by higher Shannon-Wiener and lower Simpson indices, while moderate urea concentrations supported the highest taxon richness. Optimized biochar-urea combinations enhanced the abundance of predatory invertebrates, particularly ants (Formicidae), without reducing overall taxonomic diversity. These findings show that urea-enriched cogongrass biochar prepared with Sargassum extract can improve soil ecological functioning through beneficial restructuring of the community of invertebrates, supporting its potential role in sustainable nutrient management and biodiversity-based restoration of degraded tropical Ultisol agroecosystem.
