Indonesia boasts a high biodiversity, intricately linked to the various ecosystems within its territories. In Majene Regency, West Sulawesi Province, for instance, there is a unique commodity in the form of pineapple, locally known as 'pondang'. One of the efforts to preserve this unique pineapple commodity is to understand the characteristics of the cultivation land that has sustained it over time. This research aimed to characterize the land in the cultivation areas of Majene's local pineapple as fundamental information for farmers to comprehend the plant growth ecosystem and manage the land optimally. The research utilized purposive random sampling based on the cultivation locations of Majene's local pineapple. Observations revealed that the cultivation land conditions for Majene's local pineapple had an average temperature ranging from 25.65 to 29.75 ºC, rainfall between 1,488.05 and 2,820.50 mm, with humidity ranging from 63.38 to 89.00%. Additionally, soil fertility conditions in the research locations indicated high nutrient retention, as shown by slightly acidic to neutral soil pH values and high Cation Exchange Capacity (CEC), although some available nutrients indicated very low to low soil fertility levels, such as potassium. Soil management significantly influenced nutrient availability, soil salinity, and alkalinity in the research locations.

Climate change causes forest fires that impact land cover damage, which can cause damage to soil properties and disrupt hydrological characteristics such as loss of spring or discharge depletion. This study aimed to assess the influence of land cover and rainfall on soil physical properties and spring discharge in the Cempaka Forest area. The study was conducted on three land covers, i.e., shrubs, pine, and non-timber forest products (NTFPs) in the Cempaka Forest area, Curah Tangkil Block, Pasuruan Regency, East Java Province. The measured parameters were soil bulk density, permeability, porosity, infiltration, daily rainfall, and spring discharge. Data analysis used analysis of variance (ANOVA) test at a 5% level, correlation test, and regression. The results showed that differences in land cover had no significant effect on soil physical properties. The correlation and regression results between rainfall and spring discharge showed that rainfall influenced spring discharge by 4%. The correlation and regression results in the medium-heavy rainfall categories influenced spring discharge by 38%.

The development in the city has caused urban areas to experience significant growth due to increased activity. One of the visible changes is the change in the use of vegetated land for built-up land. The research location is in a peri-urban area of Depok and Mlati subdistrict, Sleman Regency. This research analyzed land use conversion in 2015-2020 and modeled land change predictions for the next 20 years (2025-2045) using Artificial Neural Network - Cellular Automata (ANN-CA). The ANN method used multiple output neurons to determine the probability of land use transition. CA was used to model land use change by applying transition probabilities. The source of land use data came from extracting SPOT images, and then the modeling process used QGIS Desktop 2.18.11 on the MOLUSCE plugin. The results showed that the peri-urban area experienced a decrease in agricultural and livestock land by 152.62 ha (2.52%) while building land increased by 148.74 ha (2.46%). The 2025-2045 land use conversion prediction shows that the reduction in agricultural land, plantations, and livestock will continue, and the land area for buildings and roads will increase.

Land use is defined as human intervention in natural and human-made resources with the aim of fulfilling spiritual and material needs. Land use is inseparable from the phenomenon of land use change. Boyolali District is certainly not exempt from the phenomenon of land use change. Land use conversion has an impact on the inconsistency between land use and its designated plan. This study aimed to analyze land use changes from 2011 to 2022 and assess the suitability of land use in 2022 with the spatial plan of Boyolali District. This study applied survey and spatial analysis methods. The overlay technique produces maps of land use changes and the suitability of land use in 2022 with the Rencana Tata Ruang Wilayah (RTRW = Regional Spatial Planning) of Boyolali District. The results of the research showed that Kabupaten Boyolali experienced a land use conversion of 210.74 km2. Kecamatan Juwangi had the largest change in land use, covering an area of 30.37 km2, while Kecamatan Banyudono had the smallest change of 1.05 km2. The suitability of land use in 2022 with the Rencana Tata Ruang Wilayah (RTRW = Regional Spatial Planning) of Boyolali District indicates a suitable class covering an area of 797.24 km2, while an unsuitable class covers an area of 297.15 km2.

Coffee (Coffea spp.) is one of the leading commodities, which contributed 42.98 percent to the export value of the annual crop agricultural sector in 2013-2020. The productivity of Robusta coffee plants in the Jember region has tended to decrease significantly over the last 5 years. Geographic Information Systems (GIS) can be used to determine the distribution of organic C and soil water content as a basis for proper land management. The results showed that the percentage of ideal distribution area for organic C content was 94.94%, and the soil water content was at a value of 6.92-18.68%, where the status of moderate soil water content dominated by 59% of the total land. The results of simple linear regression analysis showed that the organic C variable (X1) had an effect of 29% and soil water content (X2) 10% productivity values. In addition, multiple linear regression analysis showed a strong influence of 63% on the value of productivity. The age factor also has an effect of 57% on the value of productivity.

Evaluation of land suitability was carried out in Kasihan District to determine the land suitability class for food plants. 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 S3, and N classes with limiting factors for water availability (wa), erosion hazard (eh), root media (rc), and nutrient retention (nr). The limiting factors that are found in the study area are the erosion hazard, soil pH, and organic C levels. Improvement efforts as an agricultural area development that can be done are making bunds to reduce slopes, giving biochar to increase organic C levels, and reducing soil pH. The limiting factors of soil texture and depth cannot be repaired. Soil texture is a property of the soil that is influenced by nature and is very difficult to change, and the depth of the soil cannot be changed unless other agricultural commodities are selected.
在卡西汉地区开展了土地适宜性评估，以确定食用植物的土地适宜性等级。这项研究旨在确定导致当地土壤肥力下降的限制因素。土地适宜性等级分为 S3 级和 N 级，其限制因素包括水分供应（wa）、侵蚀危害（eh）、根系介质（rc）和养分保持（nr）。研究区域的限制因素包括侵蚀危害、土壤 pH 值和有机碳含量。作为农业区的发展，可以采取的改进措施包括修建堤坝以减少坡度，施用生物炭以增加有机碳含量，以及降低土壤 pH 值。土壤质地和深度是无法修复的限制因素。土壤质地是受自然影响的土壤特性，很难改变，而土壤深度也无法改变，除非选择其他农产品。

Citrus plants (Citrus sp.) are most plants that grow in Petungsewu Village, Dau District. The decreased productivity of citrus plants causes the availability of citrus plants also to decrease. This needs to be increased to meet citrus plants' needs. The influence of soil organic matter is the main factor causing a decrease in the productivity of citrus plants in Petungsewu Village, Dau District. Therefore, it is necessary to estimate soil organic matter using the NDVI vegetation density index to obtain adequate and efficient results. Reliability testing was also carried out to know the accuracy level of the estimates made. The research was conducted at the Citrus Plantation and Subtropical Fruit Research Institute in Petungsewu Village, Dau District, Malang Regency. Estimation of soil organic matter using the NDVI vegetation density index showed an accuracy rate of 81.1%. The results of the accuracy analysis were strengthened by the presence of a paired t-test with a value of t = 0.01 and a value of p = 0.991.

Organic agriculture must be applied in an integrated manner, from upstream to downstream, forming a system. This subsystem is part of the market-oriented agribusiness concept by paying attention to quantity, quality, and continuity to gain income and agricultural productivity profits. This study aimed to look at the development of organic rice farming in the Serdang Bedagai Regency from a regional (spatial), agribusiness, and economic point of view. ANN analysis involves distance variables between agribusiness subsystems, road infrastructure, and transportation. The results of the analysis showed that the spatial pattern of organic rice formed in the Serdang Bedagai Regency was distributed, especially in Lubuk Bayas Village and Tanah Merah Village, with each having a value of R = 2.81 (R> 1) and R = 6.15 (R>1). Pematang Setrak Village had a clustered spatial pattern or had a value of R = 0.12 (R<1). This shows that the closer the locations between the subsystems are, the more profitable it is, thus saving production and transportation costs. The gains obtained were strengthened by the results of the R/C ratio produced, namely Tanah Merah Village with a value of 1.36, Lubuk Bayas Village with a value of 1.39, and Pematang Setrak Village with a value of 1.48. This means that farming activities are pretty efficient.

Maize is the main strategic food crop in Indonesia's food supply, but the productivity of maize in Indonesia is still low. Increasing the productivity of maize can be done by understanding information about the characteristics of the soil on maize planting areas. The research aimed to evaluate the relationship of soil biological and chemical characteristics (available P, phosphate solubilizing bacterial population, arbuscular mycorrhizal fungal population, organic C, and cation exchange capacity) on maize plant productivity. The research was carried out in Cibugel District, Sumedang Regency. The research used descriptive survey and comparative methods on 18 soil samples. The maize planting area was obtained based on analysis and overlapping of land units in the form of; slope, elevation, climate and shelled maize production area. Maize planting land is at an altitude of 500-1,000 meters above sea level and with a slope of 10-30%. The results of correlation analysis showed that organic C, cation exchange capacity, and phosphate solubilizing bacteria had a positive correlation with maize productivity, while available P and arbuscular mycorrhizal fungi had a negative correlation. organic C had the highest close relationship with a value of r = 0.43, while the other parameters have a weak relationship.

The level of land suitability for lowland rice can be determined by conducting a land suitability evaluation. Information related to land suitability classes can be used as a reference in taking appropriate action in managing rice fields so that production targets can be achieved. The aim of this research is to determine the actual land suitability class for lowland rice crops in Suka Maju Village, Malind District, Merauke Regency. This research used a survey method and soil sampling was carried out on two types of land, namely paddy fields and grasslands. Data collection was carried out by direct observation, laboratory analysis and data analysis. The data analysis technique to determine the subclass of land suitability is to match the growing requirements for lowland rice plants with the quality and characteristics of the land according to the Technical Guidelines for Land Evaluation for Agricultural Commodities, 2011 Revised Edition. The results of the research show that the land suitability class for lowland rice plants is on both types of land. (rice fields and grasslands) are classified as marginal suitability class (S3) with the limiting factors being rooting media (rc), nutrient retention (nr) and available nutrients (na). Basically, the limiting factors in this research can be improved by liming, fertilizing and adding organic materials.
