Abstract

Introduction: Nutrient-poor soil can lead to reduced crop yields. Biochar-organic fertilizer has demonstrated positive effects over several growing seasons. However, the efficacy of biochar-organic fertilizers varies based on the raw materials used and the duration of their application in the soil. This study aims to assess the residues of biochar, manure, and compost one year after their application on maize plants in Alfisol. Methods: A 300 kg/ha dosage was employed for a single treatment of biochar, manure, and compost. Additionally, biochar was combined with manure or compost at a dose of 150 kg/ha each. The experiment utilized a randomized block design with nine treatments and three replications, including a control group. The treatments comprised biochar made from coconut shell and husk, compost, manure, shell+compost biochar mixture, shell+manure biochar mixture, husk+compost biochar mixture, and husk+manure biochar mixture. Corn variety Pertiwi 3 was harvested upon reaching physiological maturity. Results: Combining husk biochar with chicken manure exhibited the most favorable response regarding plant height, leaf area, and weight. Furthermore, combining cob biochar and chicken manure yielded optimal cob length, weight without seeds, and seed weight. Conclusion: After one year, applying shell biochar mixed with manure demonstrated the most significant residual effect on corn plants.

Abstract

The utilization of urea compost and fluid natural manure (LOF) is extremely fundamental for rice plants. Urea contains high measures of nitrogen which can be consumed by plants rapidly and is significant for plant vegetative development. Fluid natural manure (LOF) gives more adjusted supplements to plants, particularly N, P and K. Fluid natural manure (LOF) likewise plays a part in further developing soil structure. This exploration means to concentrate on the impact of utilizing different dosages of urea compost and fluid natural manure (LOF) on the development and yield of rice plants. The examination will begin from October to December 2023 and will be done in the Science Techno Park garden at Tribhuwana Tunggadewi College. Non-factorial Randomized Block Configuration comprising of 4 medicines and 5 replications, each with urea manure portions of 0 kg/ha, 200 kg/ha, 400 kg/ha, and POC 100 cc/15 L of water. Plant level, wet and dry load of stover, and dry load of grain were the factors noticed. The examination of fluctuation test was utilized to investigate the perception information, trailed by the most un-massive distinction test (SRD 5%). The exploratory outcomes showed that the organization of different portions of urea compost and the utilization of LOF truly affected every noticed variable. The 400 kg/ha urea manure treatment gave the best grain dry weight (52.6 g/bunch). A urea portion of 200 kg/ha is comparable to the suggested utilization of POC in expanding stover weight and grain yield.

Abstract

Celery (Apium graveolens L.) is a leaf vegetable and medicinal plant usually used as a cooking spice. Several countries, including Japan, China, and Korea, use the leaf stalks as a food ingredient. The demand for celery continues to increase yearly, both domestically and abroad. Celery cultivation is rarely done in big cities because environmental conditions are unsuitable for growth requirements. Fertilization technology is one of the determinants in efforts to improve the quality and quantity of agricultural products. The use of appropriate fertilizer is expected to achieve economically profitable production levels. Fertilization essentially provides nutrients into the soil so plants' nutrient needs can be met. This research aims to determine the best use of organic fertilizer in increasing the growth and yield of celery plants. This research was conducted from June to September 2024 and is located in Tirto Rahayu, Rambaan Hamlet, Dau District, Malang Regency, East Java. This research used a Randomized Block Design with 7 treatments and 4 replications consisting of A1 (22 grams of urea), A2 (2.5 grams of humus), A3 (200 grams of goat manure), A4 (200 grams of chicken manure mixed with husks), A5 (2.5 grams of humus + 22 grams of urea), A6 (200 grams of goat manure + 22 grams of urea), and A7 (200 grams of chicken manure + 22 grams of urea). The research showed that A3 (200 grams of goat manure per plant) gave the best results, affecting plant height, number of leaves, wet weight, and volume of celery.

Abstract

Degraded soil that loses many nutrients becomes unproductive and is therefore less suitable for agriculture. One of the efforts to improve degraded soil is by adding organic materials, such as biochar and cow manure. Biochar as a soil ameliorant has been proven to improve the physical, chemical and biological properties of the soil. When combined with manure, plants production will be much more optimal. This study aims to study the effects of biochar residue and cow manure in the second planting season on the growth and yield of cauliflower plants in paddy fields. The study was conducted in August - October 2023 in Lowokwaru District, Malang City. The study used a 1-factor Randomized Block Design (RBD) which was a mixture of biochar residue and cow manure consisting of 7 treatments, namely P0 (control), P1 (100% cow manure), P2 (100% biochar), P3 (80% biochar: 20% cow manure), P4 (60% biochar: 40% cow manure), P5 (40% biochar: 60% cow manure), P6 (20% biochar: 80% cow manure). Based on the results of the study, the treatment of biochar residue and cow manure had a positive effect on the growth and yield of cauliflower plants. The treatment of 60% biochar residue: 40% manure (P4) was the best treatment for harvest results, namely the best crop and leaf weight of 485.89 g, crop weight of 274.11 g and harvest yield of 7.57 tons/ha compared to the control of 5.54 tons/ha.

Abstract

Industri lontong rumah tangga di Indonesia sering menggunakan daun pisang sebagai pembungkus, dan limbah ini memiliki potensi besar untuk dimanfaatkan lebih lanjut salah satunya pengomposan. Pengomposan secara konvensional sering kali memakan waktu yang lama, karena kandungan serat tinggi pada daun pisang yang tidak mudah terurai secara alami. Alternatif untuk mempercepat proses dekomposisi limbah ini dengan menggunakan maggot dari lalat Black Soldier Fly (BSF). Maggot dapat mempercepat proses dekomposisi limbah organik, termasuk daun pisang, dan mengubahnya menjadi pupuk berkualitas tinggi yang mengandung nitrogen, fosfor, dan kalium lebih banyak. Kegiatan pengabdian masyarakat dilakukan melalui sosialisasi dan demonstrasi untuk mengolah limbah daun pisang menjadi kompos dengan bantuan maggot. Kegiatan pengabdian bertujuan untuk memberdayakan masyarakat dalam memanfaatkan limbah daun pisang melalui pelatihan pembuatan komposter secara mandiri. Program ini merupakan bagian dari Pembinaan Industri Rumah Tangga-Usaha Mikro (IRT-UM) Berbasis Kemitraan Klaster (I), yang dilaksanakan dari bulan Oktober hingga Desember 2024. Hasil dari proses ini tidak hanya mengurangi limbah tetapi juga menciptakan produk bernilai tambah untuk pertanian. Pengelolaan limbah organik melalui maggot bukan hanya ramah lingkungan tetapi juga mendukung pertanian berkelanjutan dan meningkatkan kesejahteraan masyarakat melalui peluang ekonomi baru. Berdasarkan hasil tersebut, pengomposan limbah daun pisang dengan bantuan maggot serta sisa makanan, sayuran, dan buah-buahan memerlukan waktu sekitar 19 hari untuk mengurai limbah sebanyak 95,5 kilogram. Hasil uji analisis di laboratorium, diketahui bahwa kandungan pupuk dengan teknik maggot yang telah dilakukan telah memenuhi standart SNI 19-7030-2004 sebagai pupuk organik terutama pada pemberian limbah daun pisang dengan kriteria kadar nitrogen (N), kadar fosfor (P), dan kadar kalium (K), menunjukkan hasil uji kandungan N = 3,94%, P = 0,89%, K = 2,42%. Secara keseluruhan kadar (N, P, K) sudah melebihi standar minimalnya dengan kandungan termasuk tinggi, serta unsur hara penting seperti Ca, Mg, Na yang sangat mendukung pertumbuhan tanaman, memiliki pH netral, dan karbon organik 30,84 %.

Abstract

Merjosari Village, Lowokwaru District, Malang City, some residents in RW 06 run a home industry producing lontong, contributing to economic growth and employment. However, this industry's growth impacts the environment, especially the accumulation of banana leaf waste from lontong wrappers. This waste is often dumped on the riverbank, resulting in a decline in environmental quality and pollution, while waste management officers cannot handle the increasing volume of waste. The remaining leaves are generally thrown away, potentially creating environmental problems if not appropriately managed, including the risk of flooding. Although often considered waste, banana leaves have the potential to be useful compost material. Proper processing of banana leaves can be an effective organic fertilizer, reduce waste volume, and utilize resources sustainably. However, the high cellulose in banana leaves can slow decomposition if not appropriately handled. Another obstacle is the lack of knowledge and access to efficient technology for processing banana leaves into compost. Environmental factors such as humidity and temperature also affect the quality of compost. Therefore, making banana leaf compost with rice husk biochar can be an effective solution that benefits the community and the environment. Training in making banana leaf compost with the addition of rice husk biochar effectively increases community capacity, reduces organic waste, and opens up new economic opportunities through environmentally friendly waste management.ABSTRAKDesa Mejosari di Kelurahan Merjosari, Kecamatan Lowokwaru, Kota Malang, sebagian warganya di wilayah RW 06 menjalankan industri rumah tangga yang memproduksi lontong, yang berkontribusi pada peningkatan ekonomi dan lapangan kerja. Namun, pertumbuhan industri tersebut berdampak pada lingkungan, khususnya penumpukan limbah daun pisang dari pembungkus lontong. Limbah ini sering dibuang di tepi sungai, yang mengakibatkan penurunan kualitas lingkungan dan pencemaran, termasuk risiko bencana seperti banjir. Meski sering dianggap limbah, daun pisang memiliki potensi sebagai bahan kompos yang berguna. Pengolahan yang tepat, daun pisang dapat menjadi pupuk organik yang efektif, mengurangi volume limbah, dan memanfaatkan sumber daya secara berkelanjutan. Namun, tinggi selulosa dalam daun pisang dapat memperlambat proses dekomposisi jika tidak ditangani dengan baik. Kendala lain adalah kurangnya pengetahuan dan akses terhadap teknologi yang efisien untuk pengolahan daun pisang menjadi kompos. Oleh karena itu, penerapan metode pembuatan kompos daun pisang dengan biochar sekam padi bisa menjadi solusi yang efektif, memberikan manfaat bagi masyarakat dan lingkungan. Pelatihan pembuatan kompos daun pisang dengan tambahan biochar sekam padi, efektif dalam menekan limbah organik, sekaligus membuka peluang ekonomi baru melalui pengelolaan sampah yang ramah lingkungan.
