Abstract

Food is a basic need that must always be met. As a country with relatively high population growth, Indonesia cannot escape the threat of the global food crisis. This is due to the increasing population growth rate, resulting in higher food consumption by the community. The aim of this research is to study food security in Kulo District using a land intensification approach, in this case fertilization and water management. This research was carried out using the tiling method in calculating productivity rates and carrying out N, P, and K analysis on soil samples to determine the level of fertility in rice fields and to estimate the projected productivity of rice fields using exponential equations so that it can project the results of rice field productivity up to the year 2045. The population growth rate in Kulo District from 2025 to 2045 is 2,06%. The highest population projection result is in 2045, reaching 15.450,59 people, with a per capita consumption of 81,044 kg per person per year in Kulo District. In calculating the rate of productivity of rice fields in Kulo District, it has decreased by 0,043%, with the lowest productivity recorded in 2045 at 32.146 kg ha-1, which is still sufficient to meet the food needs of the people in Kulo District. The highest N content analysis results were found in U1 (0,44%). The highest P analysis results were found in U5 (14,92 ppm). The highest K nutrient content was in sample U4 (0,26). Food conditions in Kulo District are still classified as surplus; however, there are problems with the fertility conditions in the rice fields. Therefore, efforts are needed to increase the fertility of the rice fields in terms of fertilization and water use.

Abstract

The strategic role of the agricultural sector in Samarinda City, particularly in North Samarinda District, supports food security and the regional economy. North Samarinda District holds a crucial position as an agricultural buffer zone in Samarinda, but in the past five years, there has been a significant decrease in horticultural production, such as tomatoes from 1,467.9 tons in 2021 to 263 tons in 2024, chilies from 236.2 tons to 129.9 tons, and shallots from 7.5 tons in 2022 to 1.1 tons in 2023. Various challenges, including climate change, land degradation, and urbanization, have contributed to a decline in agricultural productivity. This study aims to evaluate land suitability to optimize horticultural crop production in the region. The research method employed is a land suitability analysis using a Geographic Information System (GIS) approach, which identifies biophysical factors such as soil texture, pH, and soil depth, as well as soil sampling for further analysis. The results show that most of the land in North Samarinda District has S3 (marginally suitable) land suitability for shallots, chilies, and tomatoes. The suitability class for S3 is influenced by limiting factors such as rainfall, soil pH, erosion, and slope. Further discussion reveals that technical improvements, such as fertilization, the addition of organic matter, and terrace construction, can enhance land suitability. Through appropriate technical improvements, land suitability can be upgraded to class S2 (moderately suitable), which in practice will support increased horticultural yields and strengthen food security in North Samarinda.

Abstract

Zn is one of the essential micronutrients for rice plants. Increasing the Cropping Index (CI) to enhanced rice productivity, leads to increased Zn absorption. Without proper micronutrient fertilization, the soil can potentially be deficient in Zn. This study aims to study the differences in the status and availability of Zn micronutrients in paddy fields based on the Rice Cropping Index. The research was conducted in Tanete village, Simbang sub-district, Maros. Sample points were determined using purposive sampling method. There were eight sample points, namely two points each in CI300 rice fields with 10 years of application, CI300 with more than 10 years, CI200 with less than 30 years, and CI200 with more than 30 years of application. The parameters observed were texture, pH, C-organic, Zn-total, and Zn-available. Correlation analysis was conducted to see the relationship between soil properties. Zn availability ranged from 0.05 - 2.47 ppm. The availability of Zn in CI300 and CI200 rice fields is lower in those with a longer age of use. This is related to the length and intensity of land use, where more Zn nutrients are mined, resulting in reduced Zn availability in the soil. Available Zn increases with the increase of soil C-Organic and Zn-total. Zn availability is classified as low to high. Zn availability in CI300 rice fields with <10 years of use is higher than with >10 years of use. The availability of Zn in CI200 rice fields with <30 years of use is higher than that of >30 years of use. Zn availability has a strong positive correlation with Zn-total and soil C-Organic, and a moderate correlation with soil pH.

Abstract

Tanah Ultisol umumnya memiliki kandungan bahan organik rendah hingga sedang, bereaksi masam, serta ketersediaan unsur hara yang rendah, sehingga berdampak pada rendahnya kesuburan tanah. Dalam kondisi tersebut, makrofauna tanah berperan penting sebagai perombak bahan organik dan pengendali proses ekologi tanah yang mendukung ketersediaan hara. Penelitian ini bertujuan untuk mempelajari kelimpahan dan keanekaragaman makrofauna tanah di berbagai vegetasi tutupan lahan di tanah ultisol. Penelitian dilakukan pada tiga tipe vegetasi, yaitu lahan kosong, lahan jati, dan lahan jagung. Pengambilan sampel makrofauna tanah menggunakan metode monolit berukuran 25 cm × 25 cm hingga kedalaman 10 cm dengan metode hand sorting pada lima titik pengamatan di setiap vegetasi. Data dianalisis menggunakan indeks keanekaragaman Shannon–Wiener, indeks dominansi, serta dianalisis hubungannya dengan sifat fisik dan kimia tanah. Hasil penelitian menunjukkan bahwa lahan jati memiliki keanekaragaman makrofauna tertinggi dengan sembilan ordo dan nilai indeks keanekaragaman sebesar H’ = 1,85. Lahan jagung memiliki tiga ordo dengan nilai H’ = 0,52 dan didominasi oleh Isoptera dengan kelimpahan populasi sebesar 160 ekor m-². Lahan kosong hanya ditemukan satu ordo, yaitu Hymenoptera, dengan nilai H’ = 0 dan kelimpahan populasi sebesar 156,8 ekor m-². Faktor pH tanah, tekstur tanah, suhu, kadar air, dan kandungan C-organik berpengaruh terhadap jumlah dan komposisi makrofauna tanah. Vegetasi tutupan lahan berpengaruh terhadap kelimpahan dan keanekaragaman makrofauna tanah pada Ultisol. Lahan dengan tutupan vegetasi yang lebih baik seperti lahan jati mampu mendukung komunitas makrofauna yang lebih beragam dan seimbang.

Abstract

Vertisol soil have high agricultural potential but are constrained by complex physical and chemical properties, thus requiring specific management strategies. This study aims to characterize the chemical properties of Vertisol soils under paddy field and dryland conditions in Jeneponto Regency and to relate them to crop productivity. The research method used was a survey with purposive soil sampling at three land-use type. Composite soil samples at a depth of 0–30 cm were analyzed in the laboratory to determine pH, organic C, total N, available P, available K, and CEC parameters. At te same thime production data were obtained through interviews. The results showed that farmers’ management practices were a more dominant factor in determining soil chemical properties than land-use systems. Organic C and total N contents tended to be higher in dryland (averaging 1.39% and 0.17%) than in paddy fields (averaging 0.71% and 0.18%). However the differences were not statistically significant based on the t-test (p > 0.05). Available P levels were very high in both land uses, indicating long-term fertilizer accumulation. Rice productivity in paddy fields (3.3–3.52 tons/ha/year) was identified as very low, which correlated directly with low organic matter content and nitrogen deficiency in the soil. Conclusion. It can be concluded that organic matter degradation resulting from management practices, such as straw removal, is the main limiting factor for rice productivity in Vertisol soils at the study site.
