This study proposes a new model for land suitability for educational facilities based on spatial product development to determine the optimal locations for achieving education targets in West Java, Indonesia. Single-aspect approaches, such as accessibility and spatial hazard analyses, have not been widely applied in suitability assessments on the location of educational facilities. Model development was performed based on analyses of the economic value of the land and on the integration of various parameters across three main aspects: accessibility, comfort, and a multi-natural/biohazard (disaster) risk index. Based on the maps of disaster hazards, higher flood-prone areas are found to be in gentle slopes and located in large cities. Higher risks of landslides are spread throughout the study area, while higher levels of earthquake risk are predominantly in the south, close to the active faults and megathrusts present. Presently, many schools are located in very high vulnerability zones (2057 elementary, 572 junior high, 157 senior high, and 313 vocational high schools). The comfort-level map revealed 13,459 schools located in areas with very low and low comfort levels, whereas only 2377 schools are in locations of high or very high comfort levels. Based on the school accessibility map, higher levels are located in the larger cities of West Java, whereas schools with lower accessibility are documented far from these urban areas. In particular, senior high school accessibility is predominant in areas of lower accessibility levels, as there are comparatively fewer facilities available in West Java. Overall, higher levels of suitability are spread throughout West Java. These distribution results revealed an expansion of the availability of schools by area: senior high schools, 303,973.1 ha; vocational high schools, 94,170.51 ha; and junior high schools, 12,981.78 ha. Changes in elementary schools (3936.69 ha) were insignificant, as the current number of elementary schools is relatively much higher. This study represents the first to attempt to integrate these four parameters—accessibility, multi natural hazard, biohazard, comfort index, and land value—to determine potential areas for new schools to achieve educational equity targets.
The study of Land Use Land Cover (LULC) is essential to understanding how land has been altered in recent years and what has caused the processes behind the change. This is significant for the future development of the area, particularly on the campus of the Universitas Padjadjaran Jatinangor. The purpose of this study was to apply remote-sensing techniques to map a university campus and vicinity by comparing the area of urban green space (UGS) and floor area ratios (FARs) of the campus in 2015 and 2017. Additionally, surface runoff analysis was also conducted. For our research, we used WorldView-2’s high-resolution satellite imagery with a resolution of 0.46 m in the Universitas Padjadjaran (Padjadjaran University, or Unpad) Jatinangor campus, Jawa Barat, Indonesia. Our approach was to interpret the imagery by running the normalized difference vegetation index (NDVI) to distinguish UGS and FAR and using digital elevation model (DEM) interferometric synthetic aperture radar (SAR) data with hydrologic analysis to identify the direction of surface runoff. The results obtained are as follows: the UGS remained more extensive compared with FAR, but the difference decreased over time owing to infrastructure development. Surface runoff has tended to flow toward the southeast in direct relation to the slope configuration.
Sustainable Development Goal (SDG) number 14 pertains to the preservation of sustainable marine ecosystems by establishing marine protected areas (MPAs). However, studies have reported massive damage to Indonesian marine ecosystems due to shipping pollution, anchors, and fishing nets. Thus, this study estimated the potential loss of ecosystem service value due to vessel activity expansion in the MPAs of Indonesia. This study was divided into three stages. The first stage is vessel activity expansion zone modeling based on kernel density. The second stage is marine ecosystem service value modeling through semantic harmonization, reclassification, and spatial harmonization. The last stage is the overlay of the vessel expansion zone model, marine ecosystem service value model, and the MPA of Indonesia. The results of this study indicate that the marine neritic zone of Indonesia has an ecosystem service value of USD 814.23 billion, of which USD 159.87 billion (19.63%) are in the MPA. However, the increase in vessel activity that occurred in 2013–2018 could potentially lead to the loss of the ecosystem service value of USD 27.63 billion in 14 protected areas. These results can assist policymakers in determining priority conservation areas based on the threat of vessel activity and value of ecosystem services.
Pendidikan merupakan hak semua orang dan memiliki peran yang sangat penting dalam kehidupan masyarakat, untuk itu kualitasnya perlu ditingkatkan. Poin ke-4 dari Tujuan Pembangunan Berkelanjutan (SDGs) Indonesia bertujuan untuk memastikan kualitas pendidikan yang inklusif dan adil. Diantaranya pada tahun 2030, memastikan bahwa semua orang menyelesaikan pendidikan dasar dan menengah secara gratis, setara, dan berkualitas. Namun kondisi satuan pendidikan di Indonesia saat ini masih perlu diperbaiki untuk memenuhi tujuan tersebut. Terdapat banyak faktor yang dapat mempengaruhi kualitas pendidikan diantaranya keamanan dari bencana alam, kenyamanan dari polusi udara, serta keterjangkauan jarak sekolah dari tempat tinggal. Provinsi Jawa Barat merupakan daerah yang sering terdampak berbagai bencana alam, polusi udara, serta memiliki masalah pendidikan yang tidak tersebar secara merata. Maka diperlukan analisis multi-aspek dari letak geografis satuan pendidikan Jawa Barat untuk menilai kualitas pendidikan ditinjau dari ketiga aspek tersebut. Penelitian ini bertujuan untuk mensintesis berbagai analisis aspek yang akan menghasilkan produk penilaian kualitas pendidikan dari ketiga aspek serta kesesuaian lahan pembuatan sekolah baru. Penelitian ini menggunakan data titik satuan pendidikan yang bersumber dari Dinas Pendidikan Jawa Barat. Terdapat 19.692 titik SD, 5.372 titik SMP, serta 4.603 titik SMA/SMK yang tersebar di Jawa Barat. Titik satuan pendidikan tersebut diintegrasikan dengan berbagai data geospasial untuk dilakukan analisis. Metode yang digunakan adalah multi-hazard assessment, overlay, serta network analysis. Hasil menunjukkan banyak satuan pendidikan berada di zona rawan bencana tinggi dan terpapar oleh berbagai polusi udara. Serta, hasil analisis keterjangkauan menunjukkan satuan pendidikan masih belum tersebar secara merata terutama daerah yang jauh dari perkotaan.
