Abstract

ABSTRACT Fruit peel waste is an organic waste material which is solid waste which, if left untreated, can cause an unpleasant odor and disrupt the comfort of the surrounding environment. Many people have used waste from fruit peels, such as making compost or organic fertilizer and so on. One use of waste from fruit peels is to use it by making ecoenzymes. The enzymes produced from fermentation are a waste management method that utilizes kitchen scraps to produce something very useful. Ecoenzymes can be used as multifunctional liquids and their applications include households, agriculture, animal husbandry, and even in the health sector. The fruit peel waste used in this research was pineapple, papaya, orange, mango and watermelon. The aim of this activity is to improve the skills of farming groups in making ecoenzymes by using pineapple, papaya, orange, mango and watermelon peels which are applied to mustard plants as liquid fertilizer. The result of this activity is that the training participants have relatively the same perception and understanding and are able to independently make ecoenzymes and apply them to soil, plants and the environment in general. Keywords: Ecoenzymes, pineapple, papaya, orange, mango, watermelon

Abstract

Appropriate land management has a long-term impact on soil performance and is believed to improve soil fertility. This study investigated the effect of eco-enzymes on soil nutrients and plant productivity of green mustard-peanut in inceptisol. The research was conducted from February to April 2025.  The experiment used a randomized block design (RBD) consisting of 5 treatments and replicated 3 times, so that there were 15 units, including N0 = without Eco-enzyme, N1 = Eco-enzyme 2cc/L. N2= Eco-enzyme 4cc/L, N3= Eco-enzyme 6cc/L, and N4= Eco-enzyme 8cc/L. The commodities used were green mustard (Brassica juncea L) and peanut (Arachis hypogaea Linn). Soil properties variables included soil pH, N-total, and P-available, while plant productivity variables included plant height, number of leaves, leaf area, fresh weight, and pod production. The results showed that the concentration of eco-enzymes had a significant effect on N-total, P-available, green mustard plant height, and peanut plant height. However, eco-enzyme concentration had no significant effect on soil pH, number of green mustard leaves, green mustard fresh weight, green mustard leaf area, number of peanut branches, and peanut pod production. The lowest production of green mustard was 0.85 tons/ha, and the highest was 3.29 tons/ha. While the lowest production of Peanut pods was 4.3 tons/ha and the highest was 6.67 tons/ha.

Abstract

Abstract Farming communities have not utilized agricultural waste and animal waste as compost optimally in overcoming the scarcity of fertilizer in farming communities. Composting is an alternative way of creating natural fertilizer made by farmers themselves, thus responding to the scarcity of fertilizer which in turn improves the health quality of the soil, produces healthy plant products, and increases farmers' income. The solutions offered in the program include the presentation of compost making materials, how to apply them to plants, assistance in plant cultivation business activities, post-harvest handling so that plant products can be maintained in a healthy manner. It is hoped that the farmers as partners who are accompanied can produce organic compost fertilizer which can increase crop production and increase their income. The aim of this program is to improve farmers' skills in utilizing plant litter, agricultural waste, animal waste to make compost fertilizer, which can then be sold on the market or used by farmers themselves to improve their vegetable cultivation business. Stages of activities include socialization, presentation of counseling material, creation of compost demonstration plots and plant cultivation demonstration plots with stages of land preparation, seeding, making plots, planting, fertilizing, watering, maintaining plants until harvest and marketing the results of cultivated plants.

Abstract

Dalam rangka peningkatan produksi pertanian sudah saatnya pengelolaan pertanian diarahkan pada input pemupukan yang ramah lingkungan dan pada lahan-lahan dengan produsktifitas yang rendah terutama dengan kondisi kesuburan rendah baik biofisik dan kimia. Pengelolaan lahan pertanian juga harus mampu memanfaatkan sisa hasil produksi yang tidak terpakai (limbah) dari tanaman maupun hewan untuk dijadikan sebagai pupuk organik. Dalam kegiatan ini sisa limbah pertanian yang digunakan adalah sebagai pupuk organik adalah pupuk kandang ayam, pupuk kandang sapi dan serasah dari cengkeh. Sedangkan media tanah pasir digunakan karena memiliki sifat kesubururan yang rendah baik biofisik dan kimia. Tujuan kegiatan ini adalah memanfaatkan sisa kotoran hewan sebagai pupuk organik dan tanah pasir dalam meningkatkan pengetahuan dan ketrampilan dalam bercocok tanaman sayuran. Sasaran peserta dalam kegiatan ini adalah kelompok tani atau petani yang mengusahakan budidaya tanaman sayuran dengan pendekatan metode penyuluhan dan diskusi mengenai budidaya tanaman serta aplikasi penerapan teknologi pertanian organik. Hasil kegiatan menunjukkan bahwa perlakuan pupuk kandang ayam, merupakan salah satu bahan organik tanah yang mampu memberikan produktifitas berat segar yang lebih baik dibandingkan dengan pupuk kandang sapi dan serasah cengkeh.

Abstract

Signs of soil that has undergone advanced development include clearer horizons, higher fine fraction and lower coarse fraction, brighter soil color, higher levels of free Al and Fe. Soil aggregation is increasing, to a certain extent organic matter and nutrient levels are increasing as well as CaCO levels, and soluble salts. Soil development is characterized by the occurrence of horizon differentiation as a representative of the process of change in the earth's skin both physically, chemically and biologically by reactions in the soil profile there is an addition of organic and mineral materials in the form of solid, liquid or gaseous materials, the disappearance of materials above the soil, the transfer of materials from one part to another in the soil body, the transfer of the form of mineral compounds and organic matter in the soil body This research was carried out in the village of Bobaneigo Madihutu, South Jailolo District, West Halmahera Regency from June to July 2023. The method used in data collection is a free survey method, which is an observation made directly in the field by determining the research location based on land use maps, and administrative maps. The variables observed were C-Organic, N-Total, C/N Ratio, CEC, KB which are soil chemical properties. The results showed that the study of the level of soil development in several types of land use has not experienced weathering or advanced development due to the low content of nutrients.
