Inceptisols dominate Indonesia's land area; therefore, future utilization needs to be maximized, especially land that has undergone extensive tillage continuously. Inceptisols have low levels of essential nutrients, especially nitrogen, phosphorus, and potassium. One of the efforts that can be made to improve nutrient content is the application of compost. This study aimed to investigate the effect of compost combined with mycorrhiza on total N, available P, exchangeable K, and soil organic C, as well as the growth and yield of sweet corn. The experimental design used in this study was a completely randomized design consisting of five treatments with three replications. Each observation parameter was analyzed using the F test at the 5% level. Parameters that significantly affected the F test were followed by the DMRT test at the 5% level. All observed data were tested for correlation using SPSS V24 to see the relationship between observation parameters. The results showed that the application of a combination of compost and mycorrhizae increased total N content by 78.7%, available P by 26.6%, soil organic C by 29.54%, plant height by 143.87cm, number of leaves by 11.33 leaves, and cob weight by 294.33 g compared to control. The correlation test showed that applying a combination of compost and mycorrhiza affected N in the soil, so the growth and yield of corn were higher.

Applications of inorganic fertilisers and pesticides frequently increase lead (Pb) content in the soil and food crops. This study aims to isolate Pb-resistant bacteria and test the isolated bacteria in reducing Pb concentration and increasing biomass production of Brassica chinensis on Pb-contaminated soil. Soil and plant samples were collected from agricultural land in Batu City, East Java, Indonesia. The isolated bacteria were tested for Pb resistance and then characterised according to 16S rRNA Sequence. A pot trial with a completely randomised block design consisting of 9 treatments and 3 replications was set to determine the effect of Pb-resistant bacteria inoculation on Pb residue, plant growth, and soil nutrients. The result showed that the isolated Pb-resistant bacteria were Bacillus wiedmannii and Bacillus altitudinis. The bacteria were resistant to Pb up to 10,000 mg/L PbNO3. Inoculation of the bacteria increased B. chinensis growth and biomass production, namely increasing the number of leaves (12%) and dry weight (35%). Also, the bacteria reduced Pb residue in the soil by up to 88%. Moreover, soil essential nutrients such as total nitrogen, available phosphorus, and exchangeable potassium increased (12%, 73%, and 200%, respectively) after the application of Pb-resistant bacteria. The bacteria have the potential for bioremediation of Pb-contaminated soils on a large scale due to the bacteria prevent Pb uptake by food crops such as B. chinensis by reducing Pb content in the soil, which is good for food safety and environmental sustainability.

The continuous use of chemical fertilizers and pesticides in soil can result in the presence of cadmium (Cd) residues that may interfere with plant growth and pose a risk of uptake by plants. The issue of soil contamination by Cd can be addressed through soil bioremediation, which involves the use of Cd-resistant bacteria and compost. The objective of this study was to analyze the impact of Cd-resistant bacteria and compost application on the growth and Cd uptake of water spinach. The research design was a completely randomized design with seven treatments: (1) control, (2) 5 mL Cd-resistant bacteria consortium, (3) 10 mL Cd-resistant bacteria consortium, (4) 10 tons/ha compost, (5) 20 tons/ha compost, (6) 5 mL Cd-resistant bacteria consortium +10 tons/ha compost, and (7) 10 mL Cd-resistant bacteria consortium +20 tons/ha compost. The results demonstrated that the application of Cd-resistant bacteria and compost did not notably impact the growth of water spinach. However, it did significantly influence the reduction of Cd uptake in water spinach. The application of the Cd-resistant bacterial consortium and compost was effective in reducing the Cd uptake of the water spinach plants in all treatments. The combination of 10 mL of bacterial isolate and 20 tons/ha of compost demonstrated the greatest reduction in Cd uptake by water spinach, reaching 73%.

Sejak 2016 Universitas Brawijaya memperoleh mandat dari Kementerian Lingkungan Hidup Kehutanan Republik Indonesia untuk mengelola kawasan hutan dengan tujuan khusus menjadi Hutan Pendidikan dan Pelatihan bernama UB Forest. Kawasan UB Forest (541 ha) awalnya berupa kawasan produksi dengan tanaman utama pinus, mahoni dan suren. Dalam perkembangannya, sekitar 70% dari luasan UB Forest telah bergeser menjadi lahan agroforestri (AF) berbasis kopi. Petani kopi di UB Forest menghadapi 2 masalah utama yaitu (1) penurunan kesuburan tanah akibat manajemen lahan yang tidak tepat dan (2) produksi kopi yang rendah (100-400 kg/ha) akibat tutupan kanopi pinus yang rapat sehingga cahaya matahari yang diterima tanaman kopi menjadi rendah. Oleh karena itu, civitas akademik UB melakukan penelitian bersama tentang “Perbaikan Manajemen Cahaya dan Ketersediaan Hara untuk pohon Kopi di UB Forest” yang hasilnya disampaikan kepada petani melalui kegiatan pengabdian masayarakat (PKM). Tujuan PKM antara lain: (1) Transfer ilmu pengetahuan tentang pengaturan cahaya dengan memangkas cabang pohon kopi dan penaungnya; (2) Membangun semangat dan memotivasi kelompok tani hutan (KTH) untuk mengelola lahan AF kopi; (3) Mengajak KTH untuk meningkatkan kesuburan tanah dan produksi kopi sekaligus menjaga lingkungan UB Forest; (4) Mendapatkan umpan balik dari petani kopi tentang hasil penelitian sebelumnya dan menggali informasi penelitian yang dibutuhkan petani untuk masa yang akan datang. Hasil kegiatan pendampingan menunjukkan peningkatan pengetahuan dan peran aktif petani dalam: (1) pengelolaan pohon penaung sebagai upaya optimalisasi intensitas cahaya untuk tanaman kopi, dan (2) perbaikan manajemen pemupukan melalui pengolahan residu panen kopi menjadi pupuk organik, dan aplikasinya untuk mengurangi penggunaan pupuk anorganik.
