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.

The Central Sleman area is a peri-urban area directly adjacent to Yogyakarta, making land conversion increasingly prevalent and unavoidable. In comparison, the Central Sleman area has a role as one of the food barns due to fertile land conditions and is suitable for agriculture. Intensive conversion of agricultural land to non-agricultural land will result in the loss of productive agricultural land, resulting in decreased rice production. This will result in high rice imports and reduced employment in the agricultural sector. This research aims to analyze the development of agricultural land use, its projection, and the carrying capacity of agricultural land in the Central Sleman Region. The calculation of the agricultural land carrying capacity is based on Odum, Howard, and Issard. The results showed that the Central Sleman Area has a decreasing rate of change in the agricultural land area every year in Kapanewon. The calculation results of agricultural land's carrying capacity show that in 2020, land's carrying capacity exceeded 0.83. The results of the projection calculation in 2024 found that 4 out of 5 Kapanewon in the Central Sleman Region cannot achieve food self-sufficiency. Therefore, efforts are needed to increase the carrying capacity of agricultural land, mainly through increasing the productivity of food crops and protecting agricultural land from land conversion.

Banjarnegara is known as a regency highly susceptible to landslides, with over half of its territory classified as having a high to very high level of landslide hazard. Mass movements in Banjarnegara, particularly within the Merawu Sub-watershed, are predominantly categorized as slides. Rainfall stands out as the primary triggering factor for landslides in this region. This study aims to dissect the causes and mechanisms behind a unique landslide event that occurred in Sarwodadi Village, Pejawaran Sub-regency, Pejawaran Regency, Central Java Province, on July 6, 2022, around 10:30 PM. Unlike typical occurrences, this landslide was not propelled by precipitation, which is commonly the principal catalyst for landslides in Banjarnegara. Employing a three-stage methodology involving secondary data collection, field observation, and data analysis, we have identified two potential explanations for the landslide event: the loss of support from the stress barrier and mass sliding. Given that the area remains an active mining site with inherent dynamics, proactive measures are imperative to mitigate the risk of future landslides. This is essential for safeguarding the safety of local mining activities, which constitute the primary source of income for many households in Sarwodadi and its environment. A comprehensive mapping and assessment initiative targeting areas with geological characteristics akin to those in Sarwodadi should be undertaken across Banjarnegara. Such endeavors would not only diminish the occurrence of landslides but also enhance public awareness concerning atypical landslide occurrences.

Monitoring soil surface moisture is a crucial aspect of drought detection and management, significantly contributing to informed decision-making in agriculture and natural resource management. Remote sensing technologies have been widely applied to predict surface soil moisture. This study aimed to develop and analyze a surface soil moisture prediction model based on remote sensing data for drought mitigation. This research was conducted in the administrative area of Sleman Regency, Yogyakarta Special Region Province. This study employed a method that integrates field measurements with remote sensing-derived data to develop a predictive model of surface soil moisture. The model was constructed using the Extreme Gradient Boosting (XGBoost) machine learning algorithm. The modeling results yielded an R² value of 0.62 and an RMSE of 0.83. The model was then applied to generate spatial estimates of surface soil moisture for the period from May to October 2024. Spatially, all six months exhibited a consistent distribution pattern, with low soil moisture levels concentrated in the central southern part of the study area. The findings can serve as a basis for highlighting land management in line with SDG Goal 15, which aims to protect, restore, and enhance the sustainable use of terrestrial ecosystems, sustainably manage forests, halt and reverse land degradation, and halt biodiversity loss.

Indonesia is characterized by a diverse topography and low to very high rainfall intensity. In addition, the population density in fertile Indonesian hilly areas is also increasing. These conditions translate to high potential for landslide hazard in Indonesia with threats of loss ranging from economic, social, to fatalities. One of the areas with a high level of landslide hazard is Padalarang Subdistrict, West Bandung Regency, West Java Province. The purpose of this research is to identify the landslide hazard in Padalarang Subdistrict, West Bandung Regency. Geographic Information System Analysis was used in this study by using an overlay technique presented on the map. The analytical method used was a survey-exploratory analysis with descriptive analysis techniques. The results showed that the landslide hazard in Padalarang Subdistrict could be divided into three categories; having landslide hazard in the north, having landslide potential in the north to the west and southeast, and having no landslide hazard in the central to southern parts which are alluvial plains. Analysis of the landslide hazard in Padalarang Subdistrict provided a spatial picture so that it could be potentially employed to be part of disaster mitigation to minimize material and non-material losses.
