Abstract

Pemerataan persebaran fasilitas pendidikan merupakan salah satu aspek penting dalam mewujudkan akses pendidikan yang berkualitas. Kecamatan Tanah Grogot sebagai pusat pemerintahan Kabupaten Paser mengalami perkembangan penduduk yang cukup pesat sehingga memerlukan penyediaan sekolah yang sesuai dengan kebutuhan masyarakat. Penelitian ini bertujuan untuk menganalisis persebaran Sekolah Menengah Pertama (SMP) Negeri di Kecamatan Tanah Grogot menggunakan Sistem Informasi Geografis (SIG), mengevaluasi kesesuaian jumlah sekolah berdasarkan Standar Nasional Indonesia (SNI) 03-1733-2004, serta menganalisis jangkauan pelayanan sekolah. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan memanfaatkan data spasial dan data sekunder yang dianalisis menggunakan Sistem Informasi Geografis (SIG), Nearest Neighbor Analysis (NNA), dan buffer analysis. Hasil penelitian menunjukkan bahwa terdapat 11 SMP Negeri yang tersebar pada 16 desa/kelurahan di Kecamatan Tanah Grogot, sementara beberapa desa belum memiliki SMP Negeri. Analisis kesesuaian berdasarkan SNI 03-1733-2004 menunjukkan bahwa beberapa wilayah belum memenuhi kebutuhan sekolah sesuai dengan jumlah penduduk. Analisis buffer menunjukkan bahwa jangkauan pelayanan sekolah masih terkonsentrasi pada wilayah pusat kecamatan sehingga sebagian wilayah pinggiran belum terlayani secara optimal. Sementara itu, hasil Nearest Neighbor Analysis menunjukkan bahwa pola persebaran SMP Negeri di Kecamatan Tanah Grogot termasuk pola tersebar (dispersed). Penelitian ini diharapkan dapat menjadi dasar bagi pemerintah daerah dalam merencanakan pemerataan pembangunan sekolah berdasarkan kondisi spasial, jumlah penduduk, dan standar pelayanan pendidikan.

Abstract

Shoreline change is an important indicator for understanding coastal environmental dynamics as it reflects the interaction between erosion and accretion processes occurring both temporally and spatially. The Batakan River Estuary, located in Panyipatan District, Tanah Laut Regency, is a coastal area influenced by the interaction of fluvial and marine processes, making it vulnerable to shoreline morphological changes. This study aims to analyze shoreline dynamics in the Batakan River Estuary during the 2020–2025 period using the Digital Shoreline Analysis System (DSAS) approach. The data consisted of shorelines extracted from Sentinel-2 imagery acquired between 2020 and 2025 and processed using Google Earth Engine. The analysis employed the Net Shoreline Movement (NSM) parameter to measure shoreline displacement and the End Point Rate (EPR) parameter to calculate the annual rate of shoreline change. The results indicate that shoreline changes occurred throughout the estuarine area, with distinct characteristics in each segment. Segment 1 was dominated by accretion, with NSM values ranging from 0.70 to 167.06 m and EPR values ranging from 0.35 to 33.41 m/year. Segment 2 exhibited a fluctuating pattern, with NSM values ranging from -19.93 to 21.37 m and EPR values ranging from -3.99 to 4.27 m/year. Segment 3 experienced the highest erosion intensity, characterized by a minimum NSM value of -79.60 m and a minimum EPR value of -15.92 m/year. Meanwhile, Segment 4 showed a mixed pattern, with NSM values ranging from 10.71 to 57.55 m and EPR values ranging from -2.14 to 11.51 m/year. These findings indicate that shoreline dynamics in the Batakan River Estuary are spatially heterogeneous, forming distinct patterns across different segments of the estuary. The spatial information generated from this study can serve as a basis for coastal zone management, environmental monitoring, erosion mitigation planning, and sustainable sediment management.

Abstract

Land cover change is an important indicator of environmental dynamics because it is closely associated with ecological function alteration, ecosystem degradation, and the sustainability of land resource utilization. Mataraman District, Banjar Regency, South Kalimantan, has experienced rapid expansion of oil palm plantations and mining activities that potentially affect environmental conditions and landscape structure. However, spatial information regarding the location, extent, and direction of land cover change remains limited, highlighting the need for more detailed information to support environmental monitoring and regional management. This study aimed to develop spatial information on land cover change from 2020 to 2025 using Sentinel-2 imagery and the Random Forest algorithm within the Google Earth Engine platform. The analysis was conducted through land cover classification, change detection, and transition matrix approaches to identify changes in area, spatial distribution, and conversion patterns among land cover classes. The results showed that secondary forest decreased by 6,026.04 ha (-30.22%), while oil palm plantations and mining areas increased by 4,422.16 ha (+22.18%) and 1,606.97 ha (+8.06%), respectively. The largest land cover conversion occurred from secondary forest to oil palm plantations, covering 4,069.57 ha, followed by secondary forest to mining areas, covering 1,537.75 ha. Change status analysis indicated that approximately 8,736.12 ha, or 44% of the total area of Mataraman District, experienced land cover change during the observation period. The spatial information generated provides a detailed representation of land cover dynamics and can serve as a supporting reference for environmental monitoring, land-use evaluation, and more adaptive regional management in response to land use change.
