Abstract

Tujuan dari penelitian ini adalah untuk mengetahui interaksi antara pupuk organik cair (POC) limbah tahu dan komposisi biochar pada media tanam, pengaruh pemberian POC limbah tahu dan pengaruh komposisi biochar pada media tanam terhadap pertumbuhan dan hasil tanaman pakcoy. Penelitian menggunakan rancangan acak lengkap (RAL) faktorial yaitu konsentrasi POC limbah tahu meliputi L1=100 mL/L air, L2=200 mL/L air, L3=300 mL/L air, dan jenis biochar meliputi S1= tanah : biochar sekam padi (1:1), S2= tanah: biochar serbuk kayu (1:1), S3= tanah: biochar sekam padi: biochar serbuk kayu (1:1:1). Hasil penelitian menujukan bahwa interaksi antara POC limbah tahu dan komposisi biochar pada media tanam serta perlakuan tunggal POC limbah tahu tidak berpengaruh signifikan terhadap semua parameter pertumbuhan dan hasil tanaman pakcoy. Perlakuan komposisi biochar berpengaruh nyata terhadap tinggi tanaman dan jumlah daun umur 35 HST, bobot segar tajuk, bobot segar akar, dan indeks panen dimana perlakuan terbaik terdapat pada komposisi media tanam S1=tanah:biochar sekam padi (1:1).

Abstract

The issue of declining soil fertility and limited access to sustainable agricultural inputs is a major challenge for smallholder farmers in Kefa Selatan, Timor Tengah Utara Regency, East Nusa Tenggara Province. In response, a community service program was initiated under the title Empowerment of KWT Mekar Sari in Kefa Selatan Subdistrict through Biochar Compost Training for Horticultural Cultivation. The objective of this activity was to enhance the capacity of local farmers, particularly members of the Mekar Sari Women Farmers Group (KWT), in producing and utilizing biochar compost to improve soil quality and increase horticultural crop productivity. The activity was carried out from July to September 2024 in Kefa Selatan and involved 15 local farmers as participants, facilitated by a team of 7 lecturers and students from the University of Timor. The methods employed included educational sessions on the benefits of compost, hands-on training in biochar compost production, and demonstration of its application in horticultural crop cultivation. As a result, participants gained practical knowledge and skills in sustainable composting techniques and showed increased awareness of organic farming benefits. The training also stimulated greater community engagement and environmental awareness. This program is expected to serve as a model for similar initiatives in other rural communities.

Abstract

Pakcoy cultivation in horticultura, organic material in the form of waste such as white oyster mushroom baglog waste. Baglog waste compost contains 2.03% N, 0.61% P and 1.78% K, this nutrient content is able to meet the nutrient needs of plants. Another organic material that can be used as a planting medium is biochar compost. Biochar compost can increase plant growth and yield. The aim of this research was to determine the comparative effect of white oyster mushroom baglog waste and biochar compost as a planting medium on the growth and yield of pak choy plants. The research used a randomized factorial design. White oyster mushroom baglog waste is the factor I have of three levels: baglog waste 0.625 kg/polybag (L1), baglog waste 1.25 kg/polybag (L2), baglog waste 1.875 kg/polybag (L3). Biochar compost is the second factor have of three levels: 0.625 kg biochar compost/polybag (B1), 1.25 kg biochar compost/polybag (B2), 1.875 kg biochar compost/polybag (B3). Each treatment was repeated 3 times so that there were 27 experimental units. The results of the was an interaction between white oyster mushroom baglog waste and biochar compost on the parameters of plant height 14-35 DAP, number of leaves 14-35 DAP, root dry weight, shoot dry weight with the best treatment of baglog waste 0.625 kg/polybag and biochar compost 0.625 kg/polybag. Providing white oyster mushroom baglog waste fertilizer had a significant effect on all observation parameters with the best treatment being baglog waste 0.625 kg/polybag.

Abstract

Pakchoi productivity in dryland areas is often constrained by water availability and suboptimal nutrient management strategies. However, the combined role of organic growing media, boron supply, and controlled irrigation in a vertical-wick fertigation system under dryland conditions remains underexplored. This study aimed to assess the presence of boron in compost- and biochar-modified growing media under water stress, which affects the morphophysiology of pakchoi in dryland conditions, using a vertical system with wick fertigation. The study was arranged in a split-plot design with two watering frequencies and a growing media formulation based on soil, compost, and biochar, with added boron. The results showed that watering frequency and boron-based growing media significantly affected leaf number, shoot and root biomass, root characteristics, and chlorophyll content. Consistent daily watering resulted in better growth and yield compared to watering every other day. Optimized combinations of regular irrigations and appropriate boron application enhanced biomass accumulation and chlorophyll content, indicating improved plant performance. These findings indicate that regular water management through a wick fertigation system, combined with organic growing media formulation and appropriate boron dosage, can significantly enhance pakchoi growth and productivity in dryland conditions. Importantly, this study provides a practical and scalable strategy for improving vegetable production under water-limited conditions.

Abstract

This community service program aims to increase vegetable production and the income of the Suka Maju Women Farmers Group in East Nusa Tenggara through the application of vertical cultivation technology as a sustainable agricultural innovation for dryland areas. The program was implemented through extension activities and training involving the village government, agricultural extension officers, and community members. The service stages included the socialization of the vertical cultivation concept, construction of installations using PVC pipes, modification of planting media based on local resources, planting and maintenance, harvesting, agribusiness management training, and program evaluation through observations and interviews. The results showed that the implementation of vertical cultivation was able to address various limitations of dryland agroecosystems, improve labor efficiency, reduce input use, and create wider marketing opportunities. Harvest results indicated an increase in production and income of more than 50% compared with conventional systems. Vertical cultivation technology proved effective as a dryland agricultural innovation capable of sustainably improving the production and income of the Suka Maju Women Farmers Group.
