Abstract

Ultisol drylands in West Kalimantan generally have low pH and high concentrations of Al and Fe ions, resulting in phosphorus (P) being less available to plants. Phosphorus is an essential nutrient that supports plant growth and increases crop yield. Phosphorus bound to Al and Fe can be released through the activity of phosphate-solubilizing bacteria (PSB). The presence of PSB is influenced by various factors, including differences in land use. This study aimed to assess the potential and population of PSB under different land uses in Kayu Tanam Village, Mandor District, Landak Regency. The research was conducted from February to April 2025, with analyses carried out at the Soil Biology and Biotechnology Laboratory, Soil Physics Laboratory, and Soil Chemistry and Fertility Laboratory, Faculty of Agriculture, Tanjungpura University. Soil samples were collected from five points arranged diagonally at each site, with 50 m spacing and a depth of 0"“20 cm. Observed parameters included population, potential, and characterization of PSB, soil pH, organic C, available P, total N, C/N ratio, bulk density, soil moisture, and soil temperature. The highest PSB population was found in maize fields (54.60 × 10⁶ CFU/g) with 22 PSB characters. The highest solubilization ability was recorded in isolate Sp22 from secondary forest (solubilization index 7.75), while the lowest was isolate Sp9 from oil palm plantation (index 1.00).

Abstract

Jagung merupakan komoditi andalan untuk Desa Binjai yang merupakan salah satu desa di Kecamatan Tayan Hulu Kabupaten Sanggau yang berjarak 166 km dari Kota Pontianak. Jagung dikembangkan pada tanah Inceptisol, karena rendahnya kesuburan tanah maka budidayanya masih secara konvensional dengan ketergantungan pada pupuk anorganik sangat tinggi. Tujuan kegiatan Pengabdian Kepada Masyarakat (PKM) adalah memberikan pelatihan pembuatan pupuk hayati dan pemanfaatannya secara kombinasi dengan pupuk kimia dan biochar kepada petani di Desa Binjai. Metode yang digunakan adalah penyuluhan, pembimbingan, pendampingan, dan evaluasi kegiatan. Hasil kegiatan memperlihatkan peningkatan pengetahuan dan keterampilan petani dalam pembuatan pupuk hayati dan biochar sebanyak 80%. Selain itu terjadi peningkatan pengetahuan dan keterampilan petani sebesar 80% dalam pengaplikasian pupuk hayati pada tanaman jagung 80%. Kata kunci: Inceptisol, pupuk hayati, jagung, desa Binjai, pupuk anorganik.   ABSTRACT Binjai Village is one of the villages in Tayan Hulu Subdistrict, Sanggau Regency. The distance from Pontianak to Binjai Village is 166 km. Most of the residents work as farmers. The crops cultivated are cassava, cayenne pepper, bananas, rubber, and palm oil. Corn is also cultivated. Corn is a staple commodity for Binjai Village. Corn is grown on Inceptisol soil. Due to the low fertility of the soil, cultivation is still conventional, with a high dependence on inorganic fertilizers. The objective of the PKM activity is to provide training on the production of biofertilizers and their use in combination with chemical fertilizers and biochar. The methods used were: counseling, guidance, assistance, and evaluation of activities. The results of the activities were: an 80% increase in farmers' knowledge and skills in making biofertilizers and biochar, and an 80% increase in farmers' knowledge and skills in applying biofertilizers to corn crops. Keywords: Inceptisol, biofertilizer, corn, Binjai village, inorganic fertilizer.
