Abstract

Black soils store a high amount of soil organic carbon (SOC) and play a crucial role in climate change, food security, and land degradation neutrality. However, data and information regarding black soils in tropical regions, including Indonesia, are limited. This study aimed to characterize and identify the utilization of black soils in Indonesia based on legacy soil survey data.  We collated 142 soil pedon samples of Mollisols from articles, technical reports, and existing datasets. The site information (site position, elevation, land use type, parent material) and selected physicochemical properties were stored in a spreadsheet, from which exploratory data analysis was conducted.  The result showed that the median SOC content was 1.53%, ranging from 0.6 to 8.2 %; cation exchange capacity was 30 cmol kg-1, ranging from 9 to 95 cmol kg-1; base saturation was 87%, ranging from 11 to 100 %; and bulk density was 1.21 g cm-3, ranging from 1.13 to 1.36 g cm-3. Other soil characteristics (particle size distribution, exchangeable bases, pH, pore, and water retention) varied with horizon type and land use/land cover. The black soils have been used for paddy fields, dryland farming, and gardens with low management intensity. Main cultivated crops include rice (Oryza sativa), corn (Zea mays), cassava (Manihot esculenta), sweet potato (Ipomoea batatas), and nutmeg (Myristica fragrans), clove (Syzygium aromaticum), coconut (Cocos nucifera), and cocoa (Theobroma cocoa).  Threats to black soil functions include soil erosion, carbon loss, and nutrient imbalance. Soil and water conservation measures, integrated soil nutrient management, and agroforestry are among the best land management practices for black soils.

Abstract

Bird’s eye chili is a type of plant with a very high market price. The low production of bird’s eye chili is influenced by factors such as water supply and seedling density, both of which affect plant growth and yield. This study aims to investigate the effects of water volume and seedling density per planting hole and their interaction on the growth and yield of bird’s eye chili. The study was conducted at the agricultural instrument standardization agency (BSIP) in Gorontalo Province from May to September 2024. The study used a factorial randomized bloch design (RBD). The first factor was water volume with three levels, and the second factor was seedling density with two levels. The parameters observed included plant height, leaf area, flowering age, number of fruits, and fruit wight. The data were analyzed using ANOVA followed by duncan’s multiple range test (DMRT) at a 5% significance level. Water volume significantly affected plant height, flowering age, and the weight of the first harvest fruit. In addition, No. interaction was found between water volume and seedling density for any of the observed parameters.

Abstract

Several pathogenic bacteria such as Staphylococcus aureus, Escherichia, Pseudomonas aeruginosa and other pathogenic bacteria have developed resistance to many marketed antibiotics. Staphylococcus aureus is already resistant to several types of antibiotics such as penicillin, erythromycin, cefoxitin, levofloxacin, and clindamycin, Escherichia is resistant to several antibiotics such as Penicillin G, Cefotaxime, Tetracycline, Ampicillin, and Amoxicillin, Pseudomonas aeruginosa has been resistant to antibiotics that target ribosomes, such as tobramycin and tigecycline. The problem of resistance of several pathogenic bacteria can be overcome by finding new metabolite compounds from Actinomycetes microorganisms that have antibiotic potential by exploring extreme areas, one of which is in the karst area, especially in plant roots. Root sampling was carried out by taking samples + 20 cm on each type of plant found. Isolation of Actinomycetes bacteria was carried out using the plate method. Antibacterial activity testing was carried out using the line method. The morphological form of the spores was seen using a SEM (Scanning Electron Microscope). The results of the study found 2 isolates of isolated plant roots containing Actinomycetes bacteria. 2 isolates showed morphological characteristics of mycelium, oval and round in shape and had various colors. The results of the antibacterial activity test showed that each isolate could inhibit several types of pathogenic bacteria, seen from the clear zone with different diameters and the results of SEM (Scanning Electron Microscopy) showed that 2 isolates had the same character and shape of spores as Actinomycetes, namely the genus Streptomyces.

Abstract

Agriculture in Indonesia is generally characterized by monoculture planting systems, continuous use of fertilizers and pesticides, increased doses and frequency of application resulting in decreased fertility, structure and biotic balance of the soil, surface water and ground water pollution, are characteristics of agricultural models that are dangerous for the ecosystem and human health. Bio Input is an environmentally friendly agricultural input using existing resources to support agricultural production, economic improvement and conservation of natural resources, as well as the independence and welfare of farmers in a sustainable manner, but there are still many farmers who have not implemented it. The purpose of this activity is to apply agricultural bio-input technology through increasing knowledge and skills to groups of farmers and housewives as a sustainable agricultural action plan in Longalo Village. The methods used are socialization, training and direct practice of product making, while data analysis uses pre-test and post-test techniques. The results obtained show that bio input technology has been implemented by farmer groups and housewives in Longalo Village, as seen from the increase in knowledge and skills in: making eco-enzymes, which initially only 60.50 people knew, to 81.25 people who knew and could make them, making compost, which initially only 67 people knew, to 88.25 people who knew and could make them, and making biopesticides, which initially only 63 people knew, to 85.50 people who knew and could make them.

Abstract

The use of solid organic fertilizer from corn waste is an alternative to support sustainable agricultural systems and reduce dependence on inorganic fertilizers. This study aims to determine the application of various doses of solid organic fertilizer from corn waste on the growth and production of land spinach plants and to determine the fertilizer dose that provides the best response. The study was conducted using a Randomized Block Design with five solid organic fertilizer doses: 0, 4, 6, 8, and 10 kg per plot. Observed parameters included plant height, number of leaves, and plant fresh weight. Data were analyzed using analysis of variance and continued with a LSD test at the 5% level if there were significant differences between treatments. The results showed that the application of solid organic fertilizer from corn waste had a significant effect on plant height at 12 and 15 days after planting and the number of leaves at 18 days after planting, but had no significant effect on plant fresh weight. A fertilizer dose of 4 kg per plot provided the best vegetative growth response compared to higher doses or no organic fertilizer.

Abstract

Desa Bulotalangi Timur merupakan salah satu sentra hortikultura di Kabupaten Bone Bolango yang terkenal dengan produksi sayur kangkung. Meskipun hasil hortikultura di desa ini cukup melimpah, terdapat permasalahan serius yaitu terjadinya penurunan produksi dari tahun ke tahun. Kondisi ini disebabkan oleh menurunnya kualitas lahan, sehingga tanah yang dimanfaatkan tidak lagi mampu memberikan hasil optimal. Oleh karena itu, diperlukan solusi yang tepat, salah satunya melalui pemanfaatan bahan organik. Tujuan dari kegiatan pengabdian ini adalah mengajak Kelompok Tani Moawota untuk memahami konsep pertanian berkelanjutan agar usaha budidaya dapat bertahan dalam jangka panjang, memperkenalkan teknologi pengelolaan limbah jagung menjadi pupuk organik serta cara mengapliaksikannya pada lahan. Metode yang digunakan dalam kegiatan ini adalah penyuluhan dan praktek langsung pembuatan pupuk organik. Pelaksanaan kegiatan diikuti oleh seluruh anggota Kelompok Tani Moawota yang berjumlah 10 orang. Materi yang diberikan meliputi penyuluhan tentang pertanian organik dan kesehatan lingkungan pertanian, penyuluhan tentang pembuatan pupuk organik berbahan dasar limbah jagung, serta praktik pembuatannya. Melalui kegiatan ini, petani memperoleh pemahaman baru mengenai pemanfaatan limbah jagung sebagai pupuk organik. Sebelumnya, sebagian besar petani hanya mengetahui bahwa pupuk organik berasal dari kotoran hewan, namun kini mereka memahami bahwa terdapat berbagai sumber bahan organik yang dapat diolah menjadi pupuk dan dimanfaatkan secara mandiri.
