Tanaman Lemna sp, merupakan jenis gulma air, yang ditemukan di danau, waduk, maupun sawah. Tanaman ini cukup potensial untuk sebagai bahan pakan ternak babi. Kualitas kimianya cukup tinggi dan terbukti dapat mendukung pertumbuhan ternak. Informasi ini masih sangat terbatas terutama di kalangan petani-peternak pedesaan. Karena itu, diperlukan upaya memperkenalkan teknis aplikasinya, sehingga memepercepat proses pengembangannya.Upaya ini menjadi penting mengingat bahwa masalah pakan selalu menjadi kendala dalam pemeliharaan ternak babi. Di samping itu, kenyataan menunjukkan bahwa, pola pemeliharaan ternak babi yang dilakukan peternak, khususnya di Kabupaten Kupang, umumnya bersifat parsial, yaitu fokus pada ternaknya saja, sedangkan pengintegrasian dengan komoditi lainnya masih terbatas. Kondisi ini membutuhkan upaya pengintegrasian antara berbagai komoditi potensial yang berorentasi pada optimalisasi manfaat, baik ekonomis, biologis, maupun ekologis. Pengintegrasian ini juga, berperan untuk saling mendukung secara berkelanjutan, antar komoditi.Situasi di atas, diakui oleh peternak mitra Program Kemitraan Masyarakat (PKM) ini.

Utilization of Agricultural Biochar Waste as Soil Conditioner for Improved Soil Quality and Result of Corn in Dryland. Optimization of degraded dryland use need to be increased through by materials soil conditioner ground added, such as biochar which made from agricultural waste. Organic soil conditioner has been shown effective to accelerate the recovery of degraded drylands caused by conventional farming. This study aims to determine the effectiveness of biochar as a soil conditioner on the soil quality improvement and yield of corn in dryland as well. Research was carried out at State Agricultural Polytechnic field practice which is located in Oesao, East Kupang, Kupang regency, East Nusa Tenggara province. Design of this study was split plot factorial with three replications. The first factor as the main plot is kind of biochar, with four types, namely: Bs: biochar cow dung; Bp: rice husks; Bg: pruned G. sepium; and Bj: corn stover. The second factor as sub plots are doses of biochar, with three levels, namely: D1: 3 t ha-1; D2: 6 t ha-1; and D3: 9 t ha-1. The results showed that no interaction between the type and dose of biochar on soil quality and yield of corn. Each single factor either main plots and sub plot gave a significant difference on the quality of soil and yield of corn. Corn stover biochar and pruned G. sepium better improve soil quality and yield of corn in dryland than biochar that made from cow dung and rice husk. Doses tested biochar also showed different results and significantly improve of the soil quality and yield of corn.

Calcareous soils have great potential for the development of food crops and horticulture, but they are constrained by high pH, low organic matter content, and less than optimal cation exchange capacity, thus affecting the availability of nutrients. This study aims to evaluate the effectiveness of organic fertilizer enriched with humic acid on soil chemical quality, nutrient uptake, and yield of shallots on calcareous soils. The study was designed with two factors, namely type of organic fertilizer (manure and bokashi) and concentration of humic acid (0%, 10%, and 20%) added to the organic fertilizer. The results of the study showed that the application of organic fertilizers, both manure and bokasih, had a similar effect on soil quality and shallot yields. However, the addition of humic acid at a concentration of 20% significantly improved the chemical properties of the soil, nutrient uptake (especially nitrogen and potassium), as well as the yield component of shallots when compared to the concentration of 10% and control. The addition of humic acid has been proven to be effective in improving nutrient availability and supporting plant growth. This innovation can be an effective solution to improve the quality of calcareous soils and agricultural products, especially shallots, which supports sustainable and environmentally friendly agriculture. Keywords: Calcareous soil, Humic acid, Nutrient uptake, Organic fertilizer, Shallots.
