The process of cultivating odot grass by some breeders is still conventional through simple land management and has not used appropriate fertilization technology, both inorganic and organic fertilizers. In this study, organic matter in the form of bokashi sludge biogas fertilizer was used as a basal fertilizer for use in the cultivation of odot grass. Soil samples collected from Kawangu Village, Pandawai District, East Sumba Regency, were analyzed at the Laboratory of Nusa Cendana University, Kupang. Soil sampling was carried out in a composite manner on plots of land to be planted with odot grass with an area of 2 x 1 m where 20 plots of land had been made. The plots of land were treated with a mixture of different bokashi sludge biogas fertilizers in soil media with each treatment, namely without bokashi fertilizer, 10 t ha-1 biogas bokashi sludge fertilizer, 20 t ha-1 biogas bokashi sludge fertilizer, 30 t ha-1 biogas bokashi sludge fertilizer, 40 t ha-1 biogas bokashi sludge fertilizer. The results of the combined criteria for soil chemical properties showed that the status of soil fertility in odot grass cultivation without bokashi sludge biogas fertilizer was in the medium soil fertility category, while the treatments with bokashi sludge biogas fertilizers of 10 t ha-1, 20 t ha-1, 30 t ha-1, and 40 t ha-1 were at high soil fertility levels.

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.

Mycorrhizae is a mutualistic symbiotic relationship between fungi and plant roots, and soil characteristics influence the performance of this symbiosis. Biopore Infiltration Hole is a vertical hole into the soil with a diameter of about 10cm and at a depth of ±100 cm in the soil for air infiltration, which is helpful in reducing the occurrence of excessive air puddles. This research was conducted to determine the effect of soil properties such as pH, total N, available P, CEC and texture on the number of spores and root colonies by arbuscular mycorrhizae on the effect of biopore infiltration holes with the addition of organic matter. The results showed that the highest number of arbuscular mycorrhizae spores and root colonies was in the biopore infiltration holes with goat manure, namely 16.3 spores 100 g-1 soil and 66.22% root colonization. The arbuscular mycorrhizal genera found included Glomus, Acaulospora, Scutellospora, and Gigaspora. The number of spores and soil properties that were positively correlated were pH (r=0.45), organic C (r=0.945**), total N (r=0.716**), available P (r=0.922**), dan CEC (r=0.894**).

Lactuca sativa L. has good economic prospects, but lettuce production often declines due to the unmet water requirement of lettuce. This study aimed to determine the water needs of lettuce on Inceptisol and Vertisol based on the Internet of Things (IoT). The location study was in the green house, Huluduotamo Village, Bone Bolango Regency, from September to October 2021, while the Vertisol and Inceptisol samples were from Sidomukti Village, Gorontalo Regency. This study used the Penman method with the Cropwat 8.0 application which was integrated with a smartphone through the Blynk (IoT) application. The water requirement yield of lettuce plants in September on Vertisol and Inceptisol in the early phase was 2.45 mm/day, the middle phase was 3.73 mm/day, and the final phase was 3.54 mm/day. Soil moisture detection device at field capacity moisture content produces 319 Analog Digital Converter (ADC) and soil in moist conditions reaches 534 ADC. The analog data value of the water content of the Inceptisol field capacity is 343 ADC and the soil in a moist state is 574 ADC. The performance of the device for detecting soil moisture in the water condition of the 15% field capacity of Vertisol and 22% Inceptisol is more effective than the gravimetric method.

Regosol has been widely used for agricultural production despite its low nutrient availability and adsorption. This research aimed to know the effects of bokashi and zeolite on the availability of nitrogen (N) in Regosol. The experiment was carried out with a completely randomized 2-factors design. The first factor was bokashi, with three levels: 0 t ha-1 (B0), 20 t ha-1 (B1), and 30 t ha-1 (B2). The second factor was zeolite with three levels: 0 t ha-1 (Z0), 5 t ha-1 (Z1), and 10 t ha-1 (Z2). Each treatment was repeated three times. Each treatment was incubated for 30 days. The parameters before being treated were texture, bulk density, pH H2O, N-totals, C-organic, available N, and CEC in soil, pH H2O, N-totals, available N, and C-organic in bokashi, also CEC in the zeolite. The parameters after being treated were pH H2O, N-totals, C-organic, C/N, available N, and CEC in soil, also leached NH4+ and leached NO3- in water. The data were analyzed with ANOVA followed by the DMRT at a 5% level. The results showed that bokashi significantly affected the available N, pH H2O, N-total, leached NO3-, and CEC, meanwhile zeolite did not significantly affect the available N but significantly affected the N-totals, C/N in soil, and leached NO3-. The combination of bokashi and zeolite did not significantly affect the available N in the soil. The best dose of bokashi increasing available N of Regosol was at a dose of 20 t ha-1 (B1).
尽管雷黄醇的养分利用率低，吸附性差，但在农业生产中得到了广泛的应用。本研究旨在了解bokashhi和沸石对Regosol中氮(N)有效性的影响。试验采用完全随机双因素设计。第一个因子为bokashi，分为0 t ha-1 (B0)、20 t ha-1 (B1)和30 t ha-1 (B2)三个水平。第二个影响因素是沸石，沸石有3个水平:0 t ha-1 (Z0)、5 t ha-1 (Z1)和10 t ha-1 (Z2)。每次治疗重复3次。各组孵育30 d。处理前的参数为土壤的质地、容重、pH H2O、N-total、C-organic、速效N、C-organic、bokashhi的pH H2O、N-total、速效N、C-organic以及沸石的CEC。处理后的参数为土壤pH H2O、总氮、有机碳、C/N、速效氮和CEC，以及水中NH4+和NO3-的浸出。对数据进行方差分析，然后在5%的水平上进行DMRT。结果表明:bokashhi对土壤有效氮、pH H2O、N-total、浸出NO3-和CEC影响显著，而沸石对土壤有效氮影响不显著，但对土壤总氮、土壤碳氮比和浸出NO3-影响显著。博卡石与沸石配施对土壤速效氮的影响不显著。bokashi增加Regosol有效氮的最佳剂量为20 t ha-1 (B1)。

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-3; 0.03 and 0.05%; 4.11 and 4.25 mg kg-1, 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). However, at a depth of 20-40 cm, it was very significant by SOC (r=0.836** or Cs=16666(SOC)-196.03; R²=0.699).

The tea plantation industry in West Java is experiencing problems with the degradation of organic matter, which can be seen from the decrease in organic C in the Bandung area and the large amount of factory solid waste produced every day. The provision of solid tea fluff as organic matter by composting can be a solution to improve the physical properties of the soil in tea plantations, and it is necessary to provide indigenous microbes to maximize plant growth in the form of Azotobacter sp. This study used a factorial randomized block design with two factors, namely soil media 100% topsoil + 0% tea fluff (F0), 70% topsoil + 30% tea fluff (F1), 60% topsoil + 40% tea fluff (F2). ), 50% topsoil + 50% tea fluff (F3), 40% topsoil + 60% tea fluff (F4), 30% topsoil + 70% tea fluff (F5) with an additional dose of Azotobacter sp. 0 mL (A0) and 3 mL (A1). The results for the soil unit weight parameter were significantly different (p<0.05), and there was an interaction between the soil media treatments and Azotobacter sp. all treatments experienced a decrease in bulk density, while the porosity parameter was not significantly different. However, for plant parameters, the F0A0 treatment showed better results than other treatments on the initial growth of tea seedlings.
西爪哇的茶园产业正面临着有机物降解的问题，这可以从万隆地区有机C的减少和每天产生的大量工厂固体废物中看出。通过堆肥方式提供固体茶绒毛作为有机物是改善茶园土壤物理性质的一种解决方案，需要提供原生微生物以固氮细菌的形式最大化植物生长。本研究采用两因子随机区组设计，即土壤介质100%表土+ 0%茶绒毛(F0)， 70%表土+ 30%茶绒毛(F1)， 60%表土+ 40%茶绒毛(F2)。， 50%表土+ 50%茶水绒毛(F3)， 40%表土+ 60%茶水绒毛(F4)， 30%表土+ 70%茶水绒毛(F5)，外加0 mL (A0)和3 mL (A1)的固氮菌sp。土壤单位质量参数差异显著(p<0.05)，土壤介质处理与固氮菌之间存在交互作用，各处理土壤容重均降低，孔隙度参数差异不显著。但在植株参数方面，F0A0处理对茶苗初始生长的影响优于其他处理。

Landslide is a form of natural phenomenon that often occurs in mountainous and hilly regions with steep up to very steep slopes. Landslide is the movement of slope-forming materials in the form of rocks, debris, soil or materials down the slope. This study aimed to identify the distribution of landslide-prone areas in Ajibarang, Banyumas Regency. The research was conducted by survey method. The model used to determine landslide-prone areas was the Stories Index Model approach. Analysis of geophysical factors was based on SPOT-5 image data and the Indonesia Topographical Map (RBI Map). Identification of land geophysical factors for susceptibility level was determined according to geological map, slope map, soil type map and land use map. The results showed that the level of landslide susceptibility in the study area was divided into 4 classes, namely very low (3.733,41 ha), low (3.303,73 ha), moderate (123,49 ha) and high (150,37 ha).

Coffee plants are one of the plantation crops that are widely cultivated by smallholders in Sumbermanjing Wetan District. The problem that is often experienced by coffee farmers is the decline in coffee production due to climate. The adverse effect of climate change can be overcome through mitigation by implementing shade plants. The saturated hydraulic conductivity of the soil is defined as the movement of water in a porous medium in a saturated state. By measuring hydraulic conductivity, it can determine the ability of the soil to conduct water and see the movement of water in the soil. The highest value of saturated hydraulic conductivity at a depth of 0-20 cm was found in coffee plants with sengon shade at 31.02 cm hour-1. The highest value of saturated hydraulic conductivity at a depth of 20-40 cm was found in coffee plants with the shade of Dadap plants, which was 56.67 cm hour-1, included in the fast category. Differences in shade and soil depth in coffee fields affect the value of the saturated hydraulic conductivity. There is a relationship between several physical properties of the soil and the saturated hydraulic conductivity of the soil. The physical properties of the soil affect the saturated hydraulic conductivity of the soil.
咖啡树是苏伯曼京魏坛地区小农广泛种植的人工林作物之一。咖啡农经常遇到的问题是气候导致的咖啡产量下降。气候变化的不利影响可以通过种植遮荫植物来缓解。土壤的饱和水力导电性被定义为水在多孔介质中处于饱和状态的运动。通过测量水导率，可以确定土壤的导水能力，看到水在土壤中的运动。在深度为0 ~ 20 cm的咖啡树中，sengon遮荫的饱和水导率在31.02 cm h -1时达到最大值。在20 ~ 40 cm深度，咖啡树的饱和水导率最高，为56.67 cm h -1，属于快类。咖啡田遮荫和土壤深度的差异会影响饱和导电性的值。土壤的几种物理性质与土壤的饱和水力导电性之间存在一定的关系。土壤的物理性质影响土壤的饱和导水率。
