Balanced fertilization in both macro and micronutrients is one strategy in soil fertility management to prevent microelement deficiencies. This fertilization type could increase plant growth and production as well as maintain soil fertility. This research aimed to examine the role of micro fertilization on supporting plant productivity and soil fertility. Research that was conducted in Dau, Malang, East Java was designed using a Randomized Block Design (RBD) with 9 treatments, ie B0 (Control), B1 (100% standard fertilization), B2 (100% standard fertilization and 50% ZnCuB), B3 (100% standard fertilizer and 100% ZnCuB), B4 (100% standard fertilizer and 150% ZnCuB), B5 (75% standard fertilizer and 50% ZnCuB), B6 (75% standard fertilizer and 100% ZnCuB), B7 (75% basic fertilizer and 150% ZnCuB), and three replications of each. 100% of basic fertilization referred to 440 kg Urea/ha, 250 kg SP-36/ha, and 350 kg KCl/ha, while 100% micro fertilizer ZnCuB (4:6:6) was 19 kg/ha. Reducing 25% of basic fertilizer combined with 150% of micro fertilizer (28.5 kg/ha ZnCuB) resulted in a significant increase in plant growth and production by 54% to control. Â Furthermore, micronutrient fertilizers could maintain soil fertility as well as prevent soil acidification.

Kalianyar, Kalirejo and Pacul villages were three villages in the Bojonegoro Regency that have tourism and creative economy potential. Kalianyar Village had Mumbul Park tourist destination, while Kalirejo and Pacul Villages have the potential in the form of community fishponds which can become tourist destinations and producers of catfish. This Strategic Community Service Activity aimed to strengthen facilities and improve community skills in utilising their potential. These community service activities included: 1) Revitalization of Mumbul Park; 2) Training on making souvenirs; 3) Improvement of fish pond and foodstalls facilities; 4) Training on catfish feed from Moringa leaves; 5) Training on making flossed catfish; 6) Improvement of catfish pond facilities and installation of biopores; 7) Catfish cultivation in buckets training; 8) Training on making catfish nuggets and chicken dimsum; 9) Socialization of food diversification and fish-eating movement; 10) Socialization of applications for halal certification.

The range between boron deficiency and toxicity in plants is utterly narrow, so that the certain dose of boron fertilizer is required for plants. Indicators of optimum boron fertilization can be measured from plant production and boron use efficiency (BUE) value. BUE influenced by the amount of soluble B-soil, type of B fertilizer, amount of boron input, type of plant, and adequacy of available macronutrients (NPK). However, excessive application of NPK base fertilizer from inorganic fertilizers can trigger soil degradation. Currently, there has not been much research that measures the reduction in the dose of NPK base fertilizer combined with boron fertilizer on plant BUE. The combination of reducing the dose of NPK base fertilizer and boron fertilizer was tested on sweet corn plants on production and BUE. This study was conducted with a randomized block design with 7 treatments, namely without fertilization (K0), base fertilization (D1), 100% base fertilization and 50–15% borate (D2–D4), and 75% base fertilization and 50–15% borate (D5–D7). The results of the initial soil analysis showed low boron content in the soil, so borate fertilization was required to provide nutrients for sweet corn plants. Application of NPK base fertilizer (100%) and addition of borate fertilizer at a dose of 50-100% (~3-6 kg/ha) significantly increased growth, plant biomass, B uptake, boron recovery efficiency (BRE), and B fertilizer efficiency ratio, compared to lower NPK-base fertilizer. Based on the estimated response curve, the recommended dose to achieve optimum-maximum sweet corn production and maximum boron recovery efficiency is 100% macro inorganic fertilization (urea, SP-36, KCl) combined with 5.72-6.75 kg/ha borate fertilizer.

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.
