Abstract

Penambahan luas lahan sawah penting dilakukan untuk meningatkan produksi padi sawah, tetapi informasi potensi lahan tersebut sering belum tersedia. Tujuan dilaksanakannya penelitian ini yaitu menentukan kelas kesesuaian lahan dan faktor pembatas penggunaan lahan untuk padi sawah, serta menilai kelayakan usahatani padi sawah. Pelaksanakan penelitian dari Juni hingga Agustus 2021 di wilayah Kecamatan Pinogu, Kabupaten Bone Bolango. Penelitian menggunakan metode pemadanan antara kriteria kesesuaian tanaman padi sawah dengan karakteristik lahan setiap satuan lahan, sehingga didapatkan kelas kesesuaian aktual dan faktor pembatas lahannya. Setelah faktor pembatas diperbaiki, maka didapatkan kelas kesesuaian potensial yang diteruskan dengan analisis kelayakan usaha padi sawah berdasarkan aspek finansial. Hasil analisis menunjukan bahwa secara aktual, kelas kesesuaian lahan didominasi sesuai marginal (kelas S3) diikuti cukup sesuai (kelas S2) untuk padi sawah di Kecamatan Pinogu Kabupaten Bone Bolango dengan pembatas adalah faktor kejenuhan basa. Selanjutnya, setelah perbaikan kelas dengan pemberian bahan organik dan kapur, maka secara potensial kelas kesesuaian lahan untuk padi sawah didominasi kelas S2 diikuti kelas S1 (sangat sesuai). Usahatani padi sawah di wilayah ini relatif menguntungkan karena R/C rasio lebih besar 1.

Abstract

Utilization of land resources requires information of the potential and limitations of land use so that the commodity that will be cultivated can achieve optimal yields. The aim of this study was to determine land suitability class of maize (Zea mays L.) of agriculture land in Popayato District, Pohuwato Regensy. This research was conducted from July 2022 to December 2022. Land suitability classes, both actual and potential, were determined based on the matching method between land characteristics of each land unit with the land suitability criteria for maize. The results showed that the actual land suitability class for maize in Popayato District was dominated by marginally suitable (S3 class) respectively at about 95.32% and not suitable (N class) about 4.68% of total area. Limiting factors consisting of class S3 includes: rainfall and humidity, soil depth, base saturation and pH, while the limiting factors in class N was soil depth. After improvement efforts were made, the potential land suitability class for maize plants became S3 class for all land units with an area of 3,587.37 ha.KeywordsSuitability; land; actual; potential; maize; Popayato

Abstract

Currently, many people know that the use of inorganic materials in plant cultivation can have negative effects on human health and the environment. So it is very necessary to increase plant productivity by implementing organic plant cultivation technology that is sustainable and environmentally friendly. Bongohulawa Village, Tilongkabila District, Bone Bolango Regency is a village where some of the population is engaged in farming and animal husbandry, but the farming community does not utilize livestock manure and plant litter waste which is used as a basic ingredient for making solid organic fertilizer. The aim of the community service activity is to provide training in making solid organic fertilizer from cow manure and rice straw litter in Bongohulawa village, Bone Bolango subdistrict. The methods used in this activity are the material provision stage and the training stage. The training stage involves carrying out demonstrations in making solid organic fertilizer for farmer groups using cow manure, rice straw litter, EM4 bioactivator as basic ingredients. During community service activities, most farmer groups have problems with a lack of knowledge about fertilizers made from organic raw materials such as cow dung waste and rice straw waste which can improve the physical, chemical and biological properties of the soil so that the farmer group community has high enthusiasm because of the material and training regarding Making organic fertilizer and rice straw is something new for farmer groups. It is hoped that the technology provided to farmer groups can be implemented when cultivating plants, in order to produce food and a healthy and sustainable environment. In conclusion, this solid organic fertilizer activity can be applied to improve soil fertility, increase production and can open up business opportunities for organic fertilizer in attractive packaging with high selling value.

ABSTRACT

Dulupi is one of the districts in Boalemo Regency which is a center for maize production, but the high intensity of maize cultivation causes a decrease in the quality of the local land. This research aimed to determine the land suitability classes and limiting factor for maize (Zea mays L.). The research was carried out in Dulupi District of Boalemo Regency from September to Desember 2022. It employed a data matching method, matching the data for each land unit with suitability criteria. The findings revealed that the level of the land suitability for maize in Dulupi District, Boalemo Regency had theree classes of land suitability, namely moderately suitable (S2) of 88% (6314,54 Ha), marginally suitable (S3) of 10% (763,89 Ha), and not suitable (N) of 2% (41,15 Ha). In contrast, the yield-limiting factors were nutrient retention, avaible nutriens (N, P, K), erosion hazard, drainage, and effetive depth. With the improvment efforts, the yield limiting factors in the potential land and suitability increased to S2 and S3 classes.

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.
