Abstract

In mining areas, improper soil management frequently leads to soil degradation and the depletion or loss of N, P, and K nutrients. Bicomat is known as an effective amendment for improving physical properties in the short term, whereas its effects on chemical properties generally become evident only in the long term. The purpose of this study was to determine the effect of combining Bicomat and Tithonia compost on the chemical properties of Group-C post-mining soil after planting mustard greens. This study was conducted from October to December 2024 at the Science Technopark of Tribhuwana Tunggadewi University, Malang City, at an altitude of approximately 450 meters above sea level. The study employed a non-factorial Randomized Block Design (RBD) with 8 treatments and 3 replications. The tested treatments consisted of: KT1 (Non-Mining Soil Control), KT2 (Group-C Mining Soil Control), T1P1B1 (Soil 1, 200 g fertilizer, 10 t ha⁻¹ Bicomat), T1P1B2 (Soil 1, 200 g fertilizer, 20 t ha⁻¹ Bicomat), T1P2B2 (Soil 1, 300 g fertilizer, 20 t ha⁻¹ Bicomat), T2P1B1 (Soil 2, 200 g fertilizer, 10 t ha⁻¹ Bicomat), T2P1B2 (Soil 2, 200 g fertilizer, 20 t ha⁻¹ Bicomat), and T2P2B2 (Soil 2, 300 g fertilizer, 20 t ha⁻¹ Bicomat). The results showed that the combination of Bicomat and compost had a significant effect on improving the chemical properties of the Group-C post-mining soil. The best results for nitrogen, phosphorus, and potassium were obtained from treatment T1P2B2, while treatments T1P1B1 and T2P1B1 yielded the best results for organic C.

Abstract. Widowati, Biru SM, Agastya IMI, Cahya UTW, Wilujeng R. 2025. Optimization of biochar and drip irrigation to improve chili yield and soil properties. Asian J Agric 9: 442-453. Cayenne pepper (Capsicum frutescens) is an important horticultural crop in Indonesia; however, its yield remains below optimal despite rising demand. This study intends to (i) assess changes in soil bulk density, particle density, and porosity; (ii) evaluate the effects of irrigation techniques and the application of biochar on chili yields; and (iii) identify the best combination for optimizing resource usage and yield. Eight different treatment combinations, each repeated four times, were used in a nested randomized design study conducted in Tunggulwulung Village, Malang. As the primary factor, the treatments included two main irrigation techniques (conventional and drip), which were further subdivided with different rates of biochar application (0%, 2%, 4%, and 6%). There were 160 pots total, with five plants per treatment acting as experimental units. Rice husks that had been pyrolyzed for three to four hours at 600°C were the source of the biochar. According to the results, adding biochar to conventional irrigation increases fruit weight by 125% and yield by about 130%. Drip irrigation with 4% biochar, on the other hand, is the most successful technique and yields much larger improvements, increasing fruit weight by 764% and fruit yield by 324%. Drip irrigation is more effective and yields better results than conventional irrigation, especially when combined with rice husk biochar. Furthermore, soil porosity and water use efficiency are significantly increased when 4% and 6% doses of biochar are added to drip irrigation systems.

Abstract

Kurangnya literasi pertanian pada anak usia dini di era digital dapat memicu fenomena plant blindness, di mana anak-anak kehilangan koneksi dengan asal-usul pangan dan kelestarian lingkungan. Pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman dan keterampilan praktis siswa sekolah dasar melalui pelatihan pembibitan tanaman hortikultura di Agroedupark Wagir. Metode yang digunakan adalah learning by doing yang meliputi tiga tahapan utama: penyampaian materi interaktif, praktik langsung pencampuran media tanam serta penyemaian benih, dan evaluasi hasil belajar. Subjek pengabdian adalah siswa Sekolah SDN 1 Jedong, Kec. Wagir. Hasil kegiatan menunjukkan peningkatan signifikan pada aspek kognitif siswa mengenai jenis tanaman hortikultura dan teknik pembibitan sederhana. Selain itu, partisipasi aktif siswa dalam praktik lapangan mencerminkan tumbuhnya minat terhadap aktivitas pertanian. Sebagai rencana tindak lanjut untuk memastikan keberlanjutan program, diterapkan program "Adopsi Bibit Mandiri". Dalam program ini, siswa bertanggung jawab merawat bibit hasil praktik di lingkungan rumah dengan pemantauan berkala melalui buku harian tanaman (logbook). Langkah ini direkomendasikan untuk memperkuat karakter tanggung jawab dan kedekatan emosional siswa terhadap alam. Pengabdian ini menyimpulkan bahwa pemanfaatan ruang publik seperti Agroedupark sebagai sarana edukasi luar ruangan efektif dalam membangun kesadaran agraris sejak dini.

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh kombinasi coal fly ash (CFA), biochar, dan pupuk organik terhadap sifat kimia tanah pasca Galian-C serta pertumbuhan vegetatif jagung. Penelitian dilaksanakan di Desa Junrejo, Kecamatan Beji, Kota Batu, menggunakan rancangan acak kelompok dengan 7 perlakuan dan 3 ulangan. Parameter yang diamati meliputi sensor tanah dan pertumbuhan vegetatif (tinggi tanaman, lingkar batang, jumlah daun, luas daun) pada 2, 4, 6, dan 8 MST. Hasil penelitian menunjukkan bahwa kombinasi CFA, biochar, dan pupuk organik berpengaruh nyata terhadap tinggi tanaman, luas daun (4 dan 6 MST), serta diameter batang (2–6 MST), namun tidak signifikan terhadap sifat kimia tanah dan jumlah daun. Perlakuan CKK (Coal Fly Ash 20 t/ha+pupuk kotoran kambing 5%) meningkatkan ketersediaan N, P, dan K, sedangkan BPK (Biochar Sabut Kelapa 20 t/ha + pupuk kompos 5%) memberikan pertumbuhan vegetatif terbaik dibanding kontrol.
