Abstract

Tomato cultivation in alluvial land requires treatments to increase productivity. The research aimed to determine the effect of interaction between chicken manure and hormonal fertilizer application on the growth and yield of tomato plants in alluvial soil. This research was conducted at the greenhouse of the Faculty of Agriculture, Science, and Technology, Panca Bhakti University from April to July 2023. A Completely Randomized Design (CRD) with a factorial pattern was employed. The treatments consisted of 2 factors. The first factor was chicken manure with 3 levels: a1= 20 g/polybag, a2= 40 g/polybag, a3= 60 g/polybag. The second factor was hormonal fertilizer with 3 levels: h1= 2 ml/l, h2= 3 ml/l, h3= 4 ml/l. The results showed that there was no interaction effect between the application of chicken manure and hormonal fertilizer on all observed variables, as well as the application of chicken manure alone. The application of hormonal fertilizer significantly affected all observed variables including plant height, number of branches, number of fruits, and fruit weight. The treatment level h2 (3 ml/l) yielded the highest result in plant height at 113.26 cm. The highest number of branches, number of fruits, and fruit weight were observed at the h3 level (4 ml/l) with values of 3.39 branches, 2.57 fruits, and a fruit weight of 86.10 grams, respectively. The treatment level h1 (2 ml/l) yielded the lowest result. Keywords: Alluvial Soil, Horticultural Commoditie, Organic Fertilizer.

Abstract

Acid sulfate soils pose significant challenges for rice cultivation due to  their extreme acidity (pH<4.0) and associated nutrient deficiencies. This study investigated the effectiveness of biochar enriched with various organic amendments in improving soil properties and rice growth in degraded acid sulfate soils. A randomized block design was employed with seven treatments: control (B0), biochar enriched with Chromolaena odorata (B1), rice straw (B2), chicken manure (B3), cattle manure (B4), Tithonia sp. compost (B5), and NPK fertilizer at half the recommended dose (B6), each applied at 10 t/ha. The experiment was conducted under greenhouse conditions using 10 kg of soil per polybag with four replications. Soil samples from Sungai Kakap, West Kalimantan,  exhibited severe constraints, including pH levels of 3.75-3.87, organic carbon content of 0.82-0.98%, and high Al and Fe contents (>3%). Results demonstrated that organic matter-enriched biochar treatments significantly improved soil chemical properties (p<0.01). Rice straw-enriched biochar (B2) achieved the highest available P (117.93 ppm) and K (1.09 cmol(+)/kg), while cattle manure-enriched biochar (B4) showed maximum organic C increase (1.30%). Plant growth parameters showed significant improvement, with B2 producing the tallest plants (137.43 cm) and B5 (Tithonia sp.) yielding the highest productive tillers (38.83). The findings indicate that biochar enriched with local organic materials, particularly rice straw and Tithonia sp., offers a sustainable solution for rehabilitating degraded acid sulfate soils while enhancing rice productivity.
Penerapan Teknologi Co-Compost Biochar untuk Meningkatkan Produktivitas Sayuran pada Kelompok Tani Mekar Jaya di Desa Sungai Rengas Kalimantan Barat: Upaya Peningkatan Kualitas Tanah Aluvial dan Produktivitas Sayuran Suryani, Rini; Masulili, Agusalim; Syafril Hayat, Edy

Abstract

Kelompok Tani Mekar Jaya di Desa Sungai Rengas, Kabupaten Kubu Raya, Kalimantan Barat menghadapi permasalahan produktivitas rendah akibat kondisi tanah pasang surut yang miskin bahan organik. Produktivitas sayuran hanya mencapai 4-6 kg per m² per musim tanam, jauh di bawah potensi optimal 10-12 kg per m². Di sisi lain, desa ini memiliki limbah organik melimpah berupa eceng gondok (500 kg/minggu) dan batok kelapa (500 kg/bulan) yang belum dimanfaatkan optimal. Program Kemitraan Masyarakat ini bertujuan memberdayakan petani melalui pengenalan dan penerapan teknologi co-compost biochar sebagai pembenah tanah berbasis potensi lokal. Metode kegiatan meliputi sosialisasi konsep pertanian berkelanjutan, pelatihan pembuatan co-compost biochar secara partisipatif, pendampingan aplikasi pada demplot sayuran, dan evaluasi menggunakan kuisioner pre-test dan post-test. Kegiatan diikuti 15 anggota Kelompok Tani Mekar Jaya selama enam bulan (Maret-Juli 2025). Hasil kegiatan menunjukkan peningkatan signifikan pada aspek pengetahuan dari 40% menjadi 82% dan keterampilan dari 45% menjadi 87%. Petani mampu memproduksi co-compost biochar secara mandiri dan mengaplikasikannya pada budidaya cabai, bawang daun, kembang kol, dan seledri. Terbentuk kesadaran baru tentang nilai ekonomi limbah organik dan pengurangan ketergantungan terhadap pupuk kimia. Inisiatif pemanfaatan pekarangan sebagai lahan produktif mulai bermunculan di kalangan petani. Teknologi co-compost biochar terbukti menjadi solusi berkelanjutan yang dapat direplikasi di wilayah lahan pasang surut lainnya untuk meningkatkan kesuburan tanah, produktivitas pertanian, dan pengelolaan limbah organik berbasis pemberdayaan masyarakat.
