Abstract

Kompleksitas proses pedogenesis pada pulau vulkanik kecil yang berpengaruh terhadap tingkat perkembangan tanah, khususnya ordo Entisol dan Inceptisol di Kelurahan Moti Kota, Kota Ternate. Kondisi iklim tropis basah, bahan induk piroklastik Kuarter–Holosen, serta variability topografi memunculkan perbedaan morfologi dan sifat fisik-kimia tanah yang signifikan. Tujuan penelitian adalah mengidentifikasi dan membandingkan variasi tingkat perkembangan profil tanah berdasarkan indikator pedogenik termasuk nisbah debu/liat, KTK/liat, rasio C/N, dan rasio Fe-oksalat/Fe-dithionit serta mendeskripsikan karakteristik morfologi, fisik, dan kimia tanah pada dua profil representatif, yakni Entisol (profil II) dan Inceptisol (profil I). Metode yang digunakan meliputi survei toposekuens dengan penggalian profil pada setiap posisi elevasi, deskripsi morfologi lapangan sesuai prosedur USDA, analisis tekstur (metode pipet), pH H₂O, kapasitas tukar kation (NH₄OAc pH 7,0), Saturasi Basa, karbon organik (Walkley–Black), total N (Kjeldahl), serta ekstraksi besi oksalat dan dithionit. Data kuantitatif dianalisis untuk menghitung nisbah indikator pedogenesis dan diklasifikasikan menurut Soil Taxonomy USDA. Hasil penelitian menunjukkan bahwa profil I (Inceptisol) membentuk horizon cambic dengan struktur gumpal menyudut, peningkatan fraksi liat dari 20 % hingga 35 %, nilai KTK 19,95–23,25 cmol(+)/kg, dan decreas­ing basa saturation dari 60 % ke 33 %. Indikator nisbah debu/liat menurun dari 1,25 pada horizon Ap ke 0,15 pada horizon Bb/C, sedangkan rasio Feₒ/Fe_d berfluktuasi menandakan proses transformasi oksida besi lanjutan. Sebaliknya, profil II (Entisol) hanya memiliki horizon A dengan tekstur lempung berpasir, KTK 20,95 cmol(+)/kg, saturasi basa 62 %, nisbah debu/liat 0,85, dan rasio Feₒ/Fe_d 1,10, menggambarkan tanah muda dengan sedikit perkembangan horizon. Kesimpulan penelitian menyatakan bahwa interaksi bahan induk vulkanik, iklim lembap tropis, organisme, topografi, dan waktu menghasilkan gradiens perkembangan tanah dari Entisol ke Inceptisol di Kelurahan Moti Kota. Pemahaman mendalam terhadap variasi ini penting untuk perencanaan penggunaan lahan berkelanjutan, di mana Inceptisol cocok untuk hortikultura intensif dan Entisol memerlukan tutupan vegetatif untuk mencegah erosi.

Abstract

Village in Ternate City has the potential to be developed as an agricultural area because the soil type is Inceptisol which is suitable for agriculture. The ability of the soil to pass water, or what is commonly called soil permeability, is one of the important components for agricultural land management. Soil structure and texture as well as other organic elements play a role in increasing the rate of soil permeability. This study aims to understand soil permeability and soil water content in Gambesi. Samples were taken at a depth of 0-20 cm (Layer I) and 20-40 cm (Layer II) on three types of land use: residential areas, mixed dry land, and clove and nutmeg plantations. Soil sampling technique used purposive random sampling method. Identification of soil properties in the field is carried out using drill identification techniques, sample rings and profiling. Parameters observed were permeability, percent soil moisture content, specific gravity, particle density and soil texture. The results showed that the soil in each layer and type of land use had a variable permeability rate of 0.63-1.91 cm/hour, with a soil moisture content of 21.6-30.43%, a density of 1.01-1.91 cm. 1.23 gram/cm3, particle density of 2.0-2.27 gram/cm3, and porosity of 39.40-55.41%. The soil texture is sandy loam and sandy clay loam. The rate of soil permeability based on land use type has a rather slow permeability class, while the soil water content is at a permanent wilting point condition.Keywords: Bulk density, particle density, porosity, soil permeability, and soil water content

Abstract

Organic materials refer to substances derived from plant or animal waste and by-products, including manure, composted rice straw, plant residues, sewage, green manure, legume cuttings, and municipal or industrial waste (Zaini et al., 2004, cited in Pirngadi, 2008). This study aims to assess the level of organic material availability and identify the factors influencing it. The parameters analyzed include soil pH, total nitrogen (Total-N), organic carbon (C-organic), organic materials, water content, and the C/N ratio. The research was conducted in Subaim, Bumi Restu Village, in the Wasile District of East Halmahera Regency.The calculation of organic material values involved multiplying the C-organic content by a factor of 1.74%. The findings reveal that the average organic material content across various types of rice field land uses ranges from moderate to high, specifically between 4.12% and 4.43%. The higher levels of organic materials are attributed to the application of rice straw and organic fertilizers during post-harvest and land preparation phases. Conversely, lower organic material values are primarily due to the significant consumption of organic matter by plants during their growth stages

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. Keywords: Training, Compost, Farmers, Production, Chaisim

Abstract

Pertanian sayuran di Desa Bobanehena, Kecamatan Jailolo, Halmahera Barat, masih menghadapi tantangan produktivitas rendah akibat ketergantungan pada pupuk kimia serta belum optimalnya pemanfaatan limbah organik. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan pengetahuan dan keterampilan petani dalam mengolah kotoran hewan dan limbah pertanian menjadi pupuk bokashi. Metode yang digunakan adalah pendekatan partisipatif, meliputi observasi, sosialisasi, pelatihan, pendampingan aplikasi, serta evaluasi. Sebanyak 22 petani sayuran terlibat sebagai peserta. Hasil kuesioner pra-pelatihan menunjukkan lebih dari 80% petani belum mengenal maupun menggunakan bokashi. Setelah pelatihan, 100% responden memahami konsep dan bahan, 90% mampu membuat bokashi secara mandiri, serta seluruhnya bersedia mengaplikasikan di lahan sayuran. Evaluasi lapangan menunjukkan bahwa bokashi meningkatkan pertumbuhan dan hasil tanaman sawi secara signifikan. Perlakuan 20 ton/ha menghasilkan tinggi tanaman 30,5 cm, jumlah daun 16 helai, dan berat segar 4,20 kg, jauh lebih tinggi dibanding kontrol 0 ton/ha (20,5 cm; 8 helai; 1,05 kg). Penerapan bokashi terbukti memberikan manfaat ekologis, ekonomi, dan sosial, sehingga berkontribusi pada pembangunan pertanian berkelanjutan berbasis sumber daya lokal.   Kata kunci: bokashi, pupuk organik, limbah pertanian, petani sayuran, pertanian berkelanjutan
