Changes in land use/land cover (LULC) in the watershed in the<br />center of Ambon City have the potential to trigger land-use change which will have an impact on land<br />degradation, water pollution, flooding, and erosion which will increase in the future. Therefore, the<br />utilization and efficiency of land cover in the watershed area must be increased based on rational land cover planning. The objectives of this study were to analyze land cover changes in watersheds in Ambon City in 2012, 2017, and 2022 and predict land cover in 2031. This study used Cellular Automata Markov Chan (CA-MC) and six factors driving the development of settlements. The results showed that from 2012, 2017, and 2022, the land cover for settlements and open land in the watershed in Ambon City continued to increase, while the land cover for non-agricultural areas and agricultural areas decreased in the area. In 2031, residential land has an area of 1,863.34 ha; this is because the residential land cover will continue to increase along with population growth and high demand for land in watersheds.</p> Heinrich Rakuasa Daniel Anthoni Sihasale Philia Christi Latue Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 473 486 10.21776/ub.jtsl.2022.009.2.29 PENENTUAN PEMETAAN KADAR AIR TANAH OPTIMAL PADA LAHAN PERKEBUNAN KELAPA SAWIT (STUDI KASUS: KEBUN CIKASUNGKA, PT PERKEBUNAN NUSANTARA VIII, CIMULANG, BOGOR) https://jtsl.ub.ac.id/index.php/jtsl/article/view/815 <p>Soil water content is one of the dynamics of water conditions that can be a limiting factor in achieving optimal oil palm productivity. The extensive oil palm plantations make it difficult to acquire soil moisture content data. Soil water content conditions can be estimated by remote sensing technology through the vegetation and drought index, and also can be mapped using an interpolation approach. This study aimed to map the optimal soil water content in oil palm plantations based on Normalized Difference Vegetation Index (NDVI), Normalized Multi-band Drought Index (NMDI), and Interpolation. The results showed that the highest soil moisture was found on 0-3% slope gradient and the lowest on 8-15% slope gradient. Vegetation density based on NDVI analysis result was quite high, while the level of dryness based on NMDI analysis result was quite humid. Mapping of soil water content based on NDVI and NMDI had a very weak correlation with soil water content so both indices are less responsive in describing soil moisture conditions in the field. Interpolated water content value had a fairly strong relationship with the soil water content and had the highest suitability, so the interpolation approach can be recommended for mapping soil water content in an oil palm plantation area.</p> Siti Faizah Zauhairah Baba Barus Enni Dwi Wahjunie Boedi Tjahjono Alfin Murtadho Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 447 456 10.21776/ub.jtsl.2022.009.2.26 PEMANFAATAN ABU TERBANG BATUBARA UNTUK MENINGKATKAN KETERSEDIAAN P, SERTA PENGARUHNYA TERHADAP PERTUMBUHAN TANAMAN KANGKUNG DARAT (Ipomoea reptans Poir) https://jtsl.ub.ac.id/index.php/jtsl/article/view/812 <p>Cultivation in sandy soils encounters many obstacles due to the nature of the soil, which has a poor ability to hold water and nutrients. In order to increase plant yield, it is necessary to add soil amendments that can improve the properties of sandy soil. The purpose of this study was to elucidate the impact of giving coal fly ash as a soil amendment on the chemical properties of soil and plants, as well as plant growth and production. The study was conducted in a greenhouse with different doses of coal fly ash applied to the growing media. The results showed that the higher dose of coal fly ash could increase the total P content (210-310%), P-available (127%), and soil Pb content (28%) compared to the control. Meanwhile, the high dose of coal fly ash can harm the growth and production of water spinach.</p> Panggah Jayengswasono Karuniawan Sigit Wicaksono Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 457 464 10.21776/ub.jtsl.2022.009.2.27 PENGARUH PENAMBAHAN BIOCHAR CANGKANG SAWIT DENGAN VARIASI SUHU PIROLISIS TERHADAP EMISI CO2 DARI TOP SOIL https://jtsl.ub.ac.id/index.php/jtsl/article/view/811 <p>Soil respiration activity is one of the contributors to carbon dioxide (CO<sub>2</sub>) emissions from the agricultural sector. The agricultural sector can also reduce the CO<sub>2</sub> emissions it produces, one of which is by making biochar from agricultural waste. Palm shells have potential as raw materials for biochar because they contain hemicellulose, cellulose and lignin. The purpose of this study was to study the effect of adding biochar with variations in pyrolysis temperature on CO<sub>2</sub> emissions resulting from the soil respiration process. Palm shell biochar was pyrolyzed with temperature variations of 500 <sup>o</sup>C and 600 <sup>o</sup>C for 1 hour and activated using NaOH. Biochar was then added to the soil at a dose of 10% and incubated for 25 days which was tested once every five days. The results showed that the highest CO<sub>2</sub> emissions occurred from soil respiration activities with the addition of palm shell biochar at a temperature of 600 <sup>o</sup>C at an incubation time of 5 days, which was 37 mg CO<sub>2</sub>. This value was 22.95% greater than the control treatment without the addition of biochar.</p> Aryo Sasmita Isnaini Isnaini Ulimaz Almira Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 439 446 10.21776/ub.jtsl.2022.009.2.25 PEMETAAN KELAS KAPABILITAS KESUBURAN TANAH SEBAGAI DASAR IDENTIFIKASI PERMASALAHAN DAN STRATEGI PENGELOLAAN LAHAN SAWAH https://jtsl.ub.ac.id/index.php/jtsl/article/view/810 <p>Farmers' lack of understanding of agricultural land characteristics leads to inaccuracy in farm management. As a result, this research aimed to classify soil fertility capability and design soil management strategies based on the limiting factor. This study took place in Malang Regency's Turen District. Soil samples were taken from 45 observation locations throughout 15 LMUs (Land Map Unit). The Fertility Capability Classification (FCC) technique was used to evaluate soil fertility classification utilizing soil texture, pH, organic C, CEC, cation base (K, Na, Ca, Mg), and base saturation. Turen District was found to have eight fertility capability classifications, including Chm (3-8 %), Chm (8-15 %), CLhm (0-3 %), CLhm (3-8 %), LChm (3-8 %), Lhm (0-3 %), Lhm (3-8 %), and Lhm (8-15 %). Single symbol C is interpreted as clay texture for both top and subsoil, as well as a single symbol for L as loamy texture. Symbol CL is interpreted as clay texture on topsoil and loamy texture on subsoil. Symbol LC is interpreted as loamy texture on topsoil and clay texture on subsoil. Symbol h in FCC class is interpreted as low pH (acid), and symbol m as low organic C. Soil pH and organic C content are the two most important limiting parameters for soil fertility.</p> Christanti Agustina Novalia Kusumarini Mochtar Lutfi Rayes Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 421 429 10.21776/ub.jtsl.2022.009.2.23 KAJIAN BEBERAPA SIFAT FISIKA TANAH YANG DITANAMI KELAPA SAWIT PADA UMUR DAN KELERENGAN YANG BERBEDA (Studi Kasus Perkebunan Sawit Kelurahan Simpang Tuan, Kecamatan Mendahara Ulu,Tanjung Jabung Timur) https://jtsl.ub.ac.id/index.php/jtsl/article/view/806 <p>Land clearing for oil palm plantations using heavy equipment will affect the physical properties of the soil, namely increasing soil compaction and decreasing soil porosity and soil moisture content. However, along with the growth of plantation crops such as oil palm, it is suspected that it can restore the physical properties of the soil. The aim of the study was to examine the differences in the physical characteristics of the soil at various ages of oil palm and the slope. The study was conducted in one of the oil palm plantations, Simpang Tuan Village, Mendahara Ulu District, Tanjung Jabung Timur Regency from March to May 2021. The study was carried out using the survey method, selecting representative areas using the Purposive Random Sampling method on oil palm plantation areas with various ages (newly planted, 5 years old, and 12 years old) and various marbles (0-3%, 3-8%, and 8-15%) with 3 replications. Parameters observed were soil texture, soil organic matter content, bulk density, water content, and soil permeability. The results showed that the older the age of oil palm plantations, the increase in organic matter content, total pore space, water content and soil permeability and a decrease in volume weight. The steeper the slope, the greater the weight of the soil volume and a decrease in the organic matter content, total pore space, water content and soil permeability.</p> Laddy Megayanti Zurhalena Zurhalena Heri Junedi Najla Anwar Fuadi Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 413 420 10.21776/ub.jtsl.2022.009.2.22 RESPON PERTUMBUHAN DAN PRODUKSI TANAMAN JAGUNG (Zea mays L.)

Application of animal waste on tailings medium will provide nutrients and help to increase water holding capacity. The purpose of this study was to determine the dose and type of animal waste that can improve the growth and yield of corn in tailings medium. This research was conducted from January to May 2021 at Experimental and Research Field (KP2), Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung. The study used a single factor randomized block design with five replicates. This study consisted of four levels of treatment there were sand tailings and cow waste 10 t ha<sup>-1</sup> (MS1), tailings sand and cow waste 20 t ha<sup>-1</sup> (MS2), tailings sand and chicken waste 10 t ha<sup>-1</sup> (MA1), tailings sand and chicken waste 20 t ha<sup>-1</sup> (MA2). Results showed that different doses and types significant affected the growth and yield of corn in tailings medium. A dose of 20 t chicken waste ha<sup>-1 </sup>showed the best growth and yield on F1 male cultivar of corn.</p> Fitri Fitri HM Saputra D Pratama SN Aini Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 431 438 10.21776/ub.jtsl.2022.009.2.24 ANALISIS STABILITAS AGREGAT DAN SIFAT FISIK TANAH DENGAN PENAUNG BERBEDA PADA SISTEM AGROFORESTRI DI LAHAN KOPI SUMBERMANJING WETAN, KABUPATEN MALANG https://jtsl.ub.ac.id/index.php/jtsl/article/view/804 <p>One of the damages that can occur in the soil structure is a decrease in aggregate stability. This study aimed to analyze the relationship between the stability of soil aggregates on a land by considering the level or type of land cover and the influence of several physical properties of the soil on coffee grounds. In this study there were four treatments with five replicates using a randomized block design at 2 depths, namely 0-20 cm deep and 20-40 cm deep. The treatments were based on different types of shade plants, namely P1 (cocoa shade), P2 (sengon shade), P3 (lantoro shade), and P4 (gamal shade). The results showed that lowest and highest soil aggregate stability values at the top depth (0-20 cm) were found in treatment P1 (cocoa shade) of 1.76 mm and P4 (gamal shade) of 3.33 mm. While at the depth of 20-40 cm, the highest and lowest values were found in the treatment P3 (lamtoro shade) of 1.92 mm and P1 (cocoa shade) of 2.37 mm. The stability of soil aggregates significantly affected soil bulk density, specific gravity, porosity, and organic matter. All treatments gave a significant effect on the thickness of the litter. The highest and lowest values were found in the treatment P4 (shade gamal) and P2 (shade sengon) of 3.4 cm and 1.7 cm, respectively.</p> Rensy Faradina Hikmawati Sugeng Prijono Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 405 412 10.21776/ub.jtsl.2022.009.2.21 EVALUASI KESESUAIAN LAHAN KECAMATAN KARANGREJA KABUPATEN PURBALINGGA JAWA TENGAH SEBAGAI UPAYA PENINGKATAN PRODUKTIVITAS KOMODITAS SAYURAN https://jtsl.ub.ac.id/index.php/jtsl/article/view/802 <p>Evaluation of land suitability was carried out in Karangreja sub-district to determine the land suitability class for vegetable commodities. This research was conducted to determine the limiting factors that resulted in a decrease in soil fertility in the local area. Land suitability classes were obtained in S2, S3, and N classes with limiting factors for water availability (wa), erosion hazard (eh), temperature (tc), root media (rc), and nutrient retention (nr). The limiting factor that’s spread evenly throughout the test area is the erosion hazard caused by the slope of the study area is classified as low to high. Improvement efforts as an agricultural area development that can be done are making drainage channels to improve the drainage system, making water absorption holes to reduce excess water on the land, making bench terraces to reduce slopes, and giving fertilizers in the form of zeolite or biochar to increase the level of soil cation exchange capacity.</p> Anggraeni Nur Hidayah Susilo Budiyanto Endang Dwi Purbajanti Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 395 404 10.21776/ub.jtsl.2022.009.2.20 PENGARUH BATUAN DAN SERESAH PADA PERMUKAAN TANAH TERHADAP PENDUGAAN LONGSOR HASIL SIMULASI https://jtsl.ub.ac.id/index.php/jtsl/article/view/797 <p>Landslide is a natural disaster that often occurs in Indonesia. The total of landslides from 2003 to 2018 is 363, which were caused by controlling factors and triggering factors or restraining factors. The relation between two factors (litter and rock) that cause landslide is still rarely researched. This research was carried out from September 2020 to March 2021, in <em>Agro Techno Park</em> Cangar and Jatimulyo Experimental Station. A simulation used an acrylic box (100 cm x 50 cm x 75 cm), with soil 20 cm thick on an aluminium plate adjusted at a slope of 50°. Rainfall intensity was set at 70 mm hour<sup>-1</sup>, using an Adjustable Water Gun (as a<em> rainfall simulator</em>) with a current of 2.6 amperes rotation sprayer A. There were eight combination treatments consisting of three factors. The variables measured were landslide duration and volume. Data obtained were then analyzed using an unpaired t-test. Apparently, the faster the landslide occurs, the larger the avalanche volume. Among the three factors observed (soil texture, litter and rocks at the surface), surface litter was the most determining factor for landslide duration and volume. Landslide duration and volume were far different between the two soil textural classes when there was no litter at the soil surface. In contrast, if there was 3 cm litter, landslide duration and volume were quite similar between the two soil textural classes. To a small extent, the occurrence of the rocks at the soil surface may fasten and increase landslide volume.</p> Oktaviani Putri Lestari Sri Rahayu Utami Christanti Agustina Copyright (c) 2022 Jurnal Tanah dan Sumberdaya Lahan https://creativecommons.org/licenses/by-nc/4.0 2022-06-30 2022-06-30 9 2 347 354 10.21776/ub.jtsl.2022.009.2.15
