The Satria neighborhood is an area where the data on the land plot work map is not neat and many land plots have not been plotted. To tidy up and complete the data on land parcels that have not been plotted, a participatory mapping program of land parcels based on work map data from BPN is carried out. This study aims to map land plots in the Satria Environment. The methods used for this study are a combination of qualitative and quantitative methods with a descriptive approach, qualitative methods in field mapping involve in-depth data collection, such as surveys, interviews, and observations, and quantitative methods are used in calculating the area of each land plot data. The results of this study show that in the Satria Environment area there are 3 classifications of land plots, namely, certified land plots with an appropriate area of 421 plots of land with a total area of 14.03 Ha with a percentage of 32.3%, certified land plots with an inappropriate area of 88 plots of land with a total area of 3.00 Ha with a percentage of 6.9% and plots of mapping results totaling 268 plots of land with a total of 268 plots of land with a total of The area reached 26.37 Ha with a percentage of 60.8%.

The increase in the number of people from year to year will certainly increase the need for land which currently, land conversion has been rampant from agricultural land to built land. Looking at the situstion that occurred in Penarukan Village, Buleleng Regency, where several agricultural lands have been converted into land for development. Therefore, mapping the use of moors, rice fields plantations and settlements is very necessary to interpret land use from UAV photos which aims to obtain up to date data that includes the distribution and area of land use. This research will use a visual interpretation elements which will be done manually, namely through on-screen digitization in ArcGIS software, Ground Check, and Interpretation Accuracy Test The results obtained from this study are the visualization of the distribution of land use from moorland by showing the distribution pattern randomly while the plantation visualization of the distribution pattern was spread evenly, and from residential land which followed the pattern of secondary transportation road, collectors and arteries while the visualization of the distribution of rice field land use where this rice field land is the most dominant land use others, with a total percentage of 45.38% with the visualization of the distribution pattern scattered randomly. The results of the classification of land use classes obtained 21 classes of land use which include Irrigation fields, Residential Houses, Mixed Gadens, Temples, Hotels, Sports Facilities, Educational Facilities, Fuel Pump Stations, Mosques, Bank Offices, Gardens, Housing, Tegalan, Stations/Terminals, Traditional Trade Centers and Health Centers. The area of the entire land use class of Penarukan village is 373.04 Ha. The accuracy level of the percentage of interpretation test results obtained is 100% based on verification of the 30 sampel points used.

Along with the increase in population density and socio-economic activities in an urban area, there is a decrease in the availability of land and the sustainability of green spaces. This research aims to map the distribution of Green Open Space (RTH) in Buleleng Sub-district. This research uses descriptive analysis method by interpreting Satellite Image with On Screen Digitization method using Google Earth Pro software in secondary data acquisition and conducting Ground Check in primary data acquisition. As for the results of this study, based on the results of visual interpretation of satellite images using Google Earth Pro software, in the Green Open Space of Buleleng Sub-district, Agricultural Green Area dominates with an area of 2756.21 Ha from the total area of Green Open Space in Buleleng Sub-district of 2871.94 Ha. The distribution of this Green Open Space has been spread evenly in each village and sub-district within Buleleng Sub-district.

This quantitative research aims to identify areas with flood potential in Candikuning Village, Baturiti District, Tabanan Regency. The study was conducted from September 2023 to May 2024. It covers various variables relevant to flood potential, namely rainfall, slope gradient, land use, soil type, and drainage density. To identify flood-prone areas in Candikuning Village, each parameter was scored based on predetermined classifications according to their respective categories. This process involved an in-depth analysis of the collected data. Once these parameters were classified, the next step was to overlay them with the Candikuning Village Administrative Map. In this study, weighted overlays were used to combine data on rainfall, slope gradient, land use, soil type, and drainage density. Each layer of information was weighted based on its importance in contributing to flood potential. The final result of this study is a flood potential map depicting areas in Candikuning Village with varying levels of flood risk. The classifications on this map are divided into five main categories: very low potential, low, medium, high, and very high. This flood potential map is expected to serve as a useful tool for local government and the community in planning flood mitigation measures, as well as in the effective management of natural resources and spatial planning.

School analysis is very important in improving the quality of education in Sawan sub-district. The school analysis can help in determining school needs, resource allocation and determining sustainable development plans. In addition, the school analysis is also used to identify and describe the condition and service potential of schools in Sawan sub-district. The objective of this study include: Analyze the level of community affordability of public school locattions in Sawan Sub-district, Buleleng Regency based on buffering analysis. Analyze the distribution pattern of public schools in Sawan Sub-district based on Nearsest Neighbor Analysis. The method used is quantitative descriptive method, data analysis includes buffer analysis, nearest neigbor analysis and field survey for data collection of coordinate points. The result of this include: analysis of school outtreach to community settlements using the buffer method, at the primary school level, an area of 56.377 Km² out of a total of 91.303 Km² of residential areas can be reached properly, identifying the reach of primary schools to settlements is evenly distributed and accessibility is very adequate. At the junior high schools level, 11 villages are well served, but 3 villages are not optimally served because the settlements are outside the radius of 1.000 meters from the nearest hunior high school. At the SMA/SMK, most residential areas can be reached, except for 1 village that is not optimally served because is is outside the radius of 3.000 meters from the nearest SMA/SMK. Analysis of the distribution pattern of public schools using the Nearest Neighbor Analysis method at 52 location point indecates a clustered or unevenly distributed pattern, with a value of T I = 0.801924 and z-score =-2,732523.
