Its superior commodities include paddy rice, tea, tobacco, coffee, and vegetable plants. In the practice of agricultural activities, it is inseparable from the use of inorganic fertilizers and persistent chemical pesticides that cause heavy metal contamination in agricultural land. Industrial waste around agricultural land that enters the water body also contributes to the accumulation of heavy metals in the soil of the water for irrigation. This study aimed to determine the distribution of heavy metal content of Pb, Cd, Ni, Co, Cr, and As on the agricultural land of Wonosobo Regency. The study was conducted on the agricultural land of Wonosobo Regency. As many as 312 soil samples were taken from a layer of sports (depth of 0-20 cm) of agricultural land in ten sub-districts of Wonosobo Regency. Soil sample analysis included heavy metals Pb, Cd, Ni, Co, Cr, As, organic Carbon, CEC, and soil texture. The analysis was carried out in an integrated laboratory, the Agricultural Environment Research Center. The results showed the concentration of heavy metals detected in Wonosobo Regency agricultural land respectively Pb &gt; Co &gt; Ni &gt; Cr &gt; As &gt; Cd. These heavy metals in the soil are still in normal concentrations and are safe for agricultural land.</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/931 SIFAT FISIK TANAH DAN PERTUMBUHAN TANAMAN PADI (Oryza sativa L.)

Giving recommended doses of fertilization through the use of multispectral camera images lead to more efficient fertilization. This study aims to analyze the impact of the application of decomposers on the implementation of a multispectral camera image-based fertilizer recommendation system on soil physical properties, growth, and crop yield. This research was carried out from November 2021 to April 2022 at the experimental field in Sukamandijaya Village, Ciasem District, Subang Regency, West Java. This study was carried out with 2 treatments, namely land without the decomposers (P1) and with the decomposers treatment (P2) on rice fields of the Mekongga variety. The decomposer used was Petro Gladiator with dose 5 liters/ha (480 ml/plot or 56 ml/m²). Data analysis was carried out by unpaired T test at 5% level to determine the effect of decomposer application on soil physical properties as well as growth and crop yield. The results showed that the application of decomposers to fertilizer recommendation systems based on multispectral camera images can improve soil conditions including improvements in soil bulk density, soil particle density, total pore space, soil moisture content pF 1, 2, and 4.2, available pore water, then soil pH, available-P soil contents, potential-K soil content, as well as rice plant height.</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/928 EFEK APLIKASI PUPUK KANDANG KAMBING DAN PUPUK N, P, K TERHADAP SIFAT KIMIA TANAH, SERAPAN P, PERTUMBUHAN DAN PRODUKSI SAWI HIJAU (Brassica juncea L.)

One of the efforts made is to provide excessive N, P, and K fertilizers. This study aimed to analyze the effect of the combined application of goat manure and N, P, K on growth, yield, P uptake, and soil chemical properties. Six treatments and three replications arranged in a randomized block design. The results showed that the combination of goat manure and N, P, K fertilizer had a significant effect (p&lt;0.05) on plant height, number of leaves, plant fresh weight, total plant P, soil pH, soil organic C, soil total N, soil C/N ratio, and soil total P, but not significantly different (p&gt;0.05) on plant dry weight, P absorption, and available P of the soil. The combination of goat manure and N, P, K fertilizer increased plant height from 36.4 cm to 50 cm (+37.4%), number of leaves from 18 to 43 leaves (+143.8%), fresh weight from 92 g to 310 g (+237%), dry weight from 10.8 g to 14.1 g (+30.6%), total crop P from 1.4% to 1.45% (+3.6%), P uptake from 15.1 g to 20.5 g (+35.2%), organic C from 0.97% to 1.25% (+28, 9%), total N from 0.35% to 0.42% (+20%), C/N ratio from 2.77 to 2.97 (+7.2%), total P from 18.9 mg 100 g-1 to 36.6 mg 100 g-1 (+26.6%), and available P from 4.22 ppm to 6.24 ppm (+49.9%).</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/927 PREDIKSI KONVERSI LAHAN PERTANIAN BERBASIS ARTIFICIAL NEURAL NETWORK-CELLULAR AUTOMATA (ANN-CA) DI KAWASAN SLEMAN BARAT 2023-05-17T15:12:35+00:00 Tiara Sarastika tiara.sarastika@upnyk.ac.id Yusuf Susena yusufsusena@mail.ugm.ac.id Dwi Kurniawan dwikurniawan47@gmail.com <p>Analysis and prediction of land conversion using spatial-temporal data are essential for environmental monitoring and better land use planning and management. The West Sleman area has the potential to experience land use changes due to anthropogenic factors. This study aimed to determine the spatial-temporal dynamics of land use change in 2012-2022 and predict future land use change using the ANN-CA model for 20 years (2022-2042). Analyzed the spatial-temporal dynamics of land use change based on land use data derived from SPOT imagery, then predicted future land use change with the ANN-CA model using the MOLUSCE plugin on QGIS Desktop 2.18.11. The simulation results showed an accuracy of 86.66% and an overall Kappa value of 83% obtained by comparing the actual data in 2022 with the simulated data on land use change in the same year. The irrigated paddy fields decreased by 6.39% (685.22 ha) due to conversion to settlements. The area of residential buildings increased by 4.65% (498.49 ha) during 2012- 2017. Predictions of land use change in 2022-2042 show that the reduction of irrigated paddy fields will continue, and the number of residential buildings tend to increase.</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/925 KLASIFIKASI WILAYAH RISIKO BENCANA BANJIR DI KOTA SEMARANG DENGAN PERHITUNGAN INDEKS VEGETASI 2023-05-01T12:41:21+00:00 Adenia Kusuma Dayanthi adeniakd@gmail.com Sri Yulianto Joko Prasetyo sri.yulianto@uksw.edu Charitas Fibriani charitas.fibriani@uksw.edu <p>Land use in an area is influenced by population growth and activities. Changes in land use continuously will cause environmental changes that often trigger an increase in natural disasters. In this study, the assessment was carried out using the calculation of the Normalized Difference Vegetation Index (NDVI), Normalized Difference Wetness Index (NDWI) and Soil Adjusted Vegetation Index (SAVI). The data used came from Landsat OLI 8 imagery data from 2020 to 2023. The results of this study showed that in the range of 2020 to 2023 the changes in the three calculations of the vegetation index were not significant. From the data obtained, the classification for calculations in the rainy and dry seasons was the same, the NDVI vegetation index obtained high vegetation, the SAVI vegetation index obtained forested vegetation, and the NDWI vegetation index obtained high wetness. Overall the assessment of the vegetation index obtained good results, and it can be concluded that not all areas in Semarang City are at risk of flooding, even during the rainy season.</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/924 MODEL PERUBAHAN TUTUPAN LAHAN BERBASIS CA-MARKOV: STUDI KASUS KECAMATAN TERNATE UTARA, KOTA TERNATE 2023-04-29T02:03:15+00:00 Panji Nurul Achmadi panji.nurul@ui.ac.id Muhammad Dimyati heinrich.rakuasa@ui.ac.id Masita Dwi Mandini Manesa heinrich.rakuasa@ui.ac.id Heinrich Rakuasa heinrichrakuasa02@gmail.com <p>North Ternate Sub-district is located in the center of Ternate City, making it a sub-district that has an increasing population every year. The increase in population certainly affects the increase in built-up land, which certainly affects environmental damage, climate change and other socio-economic problems. This study aims to predict land cover change in North Ternate Sub-district in 2003, 2013, 2023 and 2032 based on CA-Markov. This research used CA-Markov method to predict land cover in 2023. The results showed that in 2003, 2013, 2023 and 2032, built-up land annually experienced an increase in area, this is certainly influenced by the increase in population, and the need for land for settlement is getting higher every year. Agricultural land, non-agricultural land and open land continue to decrease in the area due to the conversion of these types of land cover to built-up land. The results of this prediction are very useful for the government in making policies related to sustainable spatial planning in the future.</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/923 ESTIMASI CADANGAN KARBON PADA TANAH BEKAS TAMBANG EMAS DI KABUPATEN DHARMASRAYA, SUMATERA BARAT 2023-04-27T08:31:22+00:00 Amsar Maulana amaulana.1005@gmail.com Mimien Harianti herviyanti@agr.unand.ac.id Teguh Budi Prasetyo herviyanti@agr.unand.ac.id Herviyanti Herviyanti herviyanti@agr.unand.ac.id <p>Climate change, deforestation, and substantial loss of agricultural land within gold mining concessions in Dharmasraya greatly affect soil carbon stocks (Cs). This study used a survey method with purposive random sampling based on variations in ex-gold mining areas in each region, at depths of 0-20 and 20-40 cm with three to five replicates with a total of 54 samples. The estimation of Cs in ex-gold mining soil was highest at a depth of 20-40 cm (5.89E2), compared to a depth of 0-20 cm (1.38E2), where bulk density (BD), soil organic carbon (SOC), and total Hg in ex-gold mining soil at a depth of 0-20 and 20-40 cm were 1.46 and 1.39 g cm<sup>-3</sup>; 0.03 and 0.05%; 4.11 and 4.25 mg kg<sup>-1</sup>, respectively. The Cs in ex-gold mining soil at a depth of 0-20 cm is very significant by BD (r=-0.522** or Cs=-628.03(BD)+1055.1; R²=0.275) and SOC (r=0.948** or Cs=4896.8(SOC)-6.4673; R²=0.8996) and total Hg (r=0.518** or Cs=81.373(Hg)-196.43; R²=0.2688).

In determining the soil fertility indicators, soil organic carbon mapping is required to provide information and demonstrate the distribution of organic carbon. In this study, remote sensing method testing was carried out by comparing data between observations in the field with rice productivity estimation data using Landsat 8 imagery. The observation was conducted on paddy fields with an area of about 4,800.86 ha in the volcanic region of Mount Talang. This research used a survey method with a grid system of 1,000 x 1,000 m intervals with a soil depth of 0-20 cm and 20-40 cm. The parameters of the soil observations carried out were bulk density, pH, and organic carbon. The results showed that Mount Talang volcanic rice fields had an estimated soil organic carbon stock of ±6,426.118 tons. A weak correlation was obtained between organic carbon and the estimated value of paddy rice productivity (r =0.024). Hence organic carbon in the study area could not be estimated with the value of lowland rice productivity.</p> 2023-07-01T00:00:00+00:00 Copyright (c) 2023 Jurnal Tanah dan Sumberdaya Lahan https://jtsl.ub.ac.id/index.php/jtsl/article/view/921 ANALISIS KEBUTUHAN AIR TANAMAN SELADA (Lactuca sativa L.)
