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

[CHLOROPHYL CONCENTRATION AND YIELD OF PAKCOY (Brassica rapa L.) AFTER TWO YEARS OF BIOCHAR AND ORGANIC FERTILIZER APPLICATION IN ENTISOLS]. While nitrogen is necessary throughout the growth of vegetable plants, N deficiency disrupts chlorophyll formation, and hence, affecting the photosynthesis process. This study aimed to study the impact of the use of biochar and organic fertilizers on chlorophyll content and yield of Pak coy mustard in the third planting season in Entisols. This research was conducted in Bawang Hamlet, Tunggulwulung Village, Malang City. The first and second planting seasons, were May-November 2017 and August 2018-January 2019, respectively. Research on the third planting season was carried out in July-August 2019 without nitrogen fertilization. The research was arranged in a randomized block design, consisting of controls (Kl), chicken manure (A), compost (K), rice husk biochar (S), rice husk biochar + chicken manure (SA), rice husk biochar + compost (SK). The results showed that after two years of application, biochar and organic fertilizers had a positive impact on the increase in yield of Pakcoy even though fertilizer was not provided. The application of biochar and compost provided the best residual effect on the total chlorophyll of Pakcoy mustard.

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.

Abstract

This study reviews the impact of pest and disease attacks on shallot plants (Allium ascalonium L.) and control strategies to increase plant production. Pests such as Spodoptera exigua (onion caterpillar), Thrips tabaci (thrips), Spodoptera ltura F. (armyworm), Liriomyza spp. (leaf slitting fly), and Gryllotalpa spp. (orong-orong), as well as diseases such as trotol or purple spot (Purple blotch), anthracnose (Antracnose), downy mildew, moler or fusarium wilt (Twisting disease), leaf blight (Stemphylium leaf blight), and leaf spot (Cercospora leaf spot) cause a significant decrease in production hasl. Pest and disease control still relies heavily on chemical pesticides, which pose a risk to the environment and health. Alternative sustainable control such as the use of biopesticides from mahogany seed extract (Swietenia mahagoni), Japanese papaya leaf extract (Cnidoscolus aconitifolius), and legundi weed extract (Vitex trifolia L.), as well as the application of Plant Growth Promoting Microorganisms (PGPM) from bamboo root can have a very good influence on controlling pests and diseases of shallot plants and can help in increasing plant productivity

Abstract

This study aims to examine the physical and chemical properties of soil, morphology, and soil classification in Dalisodo Village, Wagir District, Malang Regency, and their implications for land management. Observations were conducted at three locations representing different land-use types: Napier grass monoculture, coffee agroforestry, and open grass. Soil morphology was described in the field, while physical and chemical analyses were conducted using standard laboratory methods. The results indicate that the soil is predominantly clay-textured, with a granular to subangular blocky structure, an acidic pH, and a very low to moderate organic carbon content. N, P, and K levels vary from low to moderate, CEC ranges from moderate to high, and base saturation ranges from low to very high. Soil classification reveals a dominance of Inceptisols and Vertisols in Udic soil moisture regimes, with soil profiles characterized by Typic Hapluderts (Point 1), Dystric Eutrudepts (Point 2), and Chromic Hapluderts (Point 3). These findings provide important information for land management, as vertisols require attention to drainage, water retention, and liming to optimize productivity. Inceptisols require organic amendments and soil fertility management to support sustainable agricultural or agroforestry systems. Emphasis on soil classification helps determine appropriate land management strategies, improves fertilizer efficiency, and supports the sustainability of the region’s agricultural ecosystem.
