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

Selama ini hampir semua KWT hanya melakukan kegiatan budidaya tanaman hortikultura maupun tanaman pangan namun belum melakukan kegiatan pengolahan produk. Hal ini yang menyebabkan jumlah stunting di Desa Tapenpah 21 orang. Untuk mengatasi hal demikian perlu adanya pangan sumber protein. Tempe merupakan sumber protein nabati yang cukup penting bagi masyarakat Indonesia yang difermentasi. Keunggulan tempe diantaranya daya cerna protein, karbohidrat dan lemaknya lebih baik; beberapa kandungan vitamin lebih tinggi, ketersediaan (bioavailabilitas) mineral menjadi lebih baik. Pelatihan pembuatan tempe dengan tujuan untuk menurunkan angka stunting. Selain itu, diharapkan menjadi nilai tambah bagi masyarakat Desa Tapenpah yaitu membuat tempe sendiri untuk dikonsumsi dan juga dapat dijual. Hal ini akan berdampak terhadap ekonomi masyarakat. Melalui KWT diharapkan wanita-wanita yang umumnya adalah ibu rumah tangga bukan saja dapat produktif dan mandiri dalam memenuhi kebutuhan pangannya tetapi juga produktif dan mandiri dalam pemenuhan kebutuhan gizi keluarga.  Oleh karena itu perlu adanya sosialisasi dan pelatihan pembuatan tempe kepada KWT sebagai penyedia makanan dalam rumah tangga. Sehingga dengan pemberian tempe, pertumbuhan berat badan penderita gizi buruk (Stunting) akan menurun dan diare menjadi sembuh dalam waktu singkat. Pengolahan kacang kedelai  menjadi tempe dapat menurunkan kadar raffinosa dan stakoisa yaitu suatu senyawa penyebab timbulnya gejala flatulensi (perut kembung).

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

Dry land soils generally have poor physical quality, requiring intensive management to be used effectively as planting media. Verticulture is applied to improve the growing medium by incorporating biochar and compost. The development of verticulture integrated with a fertigation system allows uniform distribution of water and nutrients along the vertical pipes. This study aimed to examine the effects of planting medium composition and boron concentration on the growth and yield of lettuce (Lactuca sativa L.) under a verticulture fertigation system. The experiment employed a split-plot design. The main plot consisted of different planting medium compositions: soil (control), 50% soil + 50% compost–biochar mixture, 75% soil + 25% compost–biochar mixture, and 25% soil + 75% compost–biochar mixture. The subplot was the boron concentration, consisting of 0 g/L (control), 1 g/L, and 1.5 g/L. The results showed that the interaction between planting medium composition and boron concentration significantly affected plant height and number of leaves at 21–28 days after planting (DAP), as well as root volume. The planting medium had a significant effect on all observed parameters, while boron concentration significantly affected plant height at 35 DAP. The combination of compost and biochar in balanced proportions, together with optimal boron concentration, enhanced lettuce growth performance in the vertical wick fertigation system.
