Abstract

Tujuan penelitian yaitu menentukan arahan zonasi sempadan sungai Bolango yang dapat digunakan untuk aktivitas wisata. Metode pengumpulan data menggunakan wawancara, observasi lapangan dan dokumentasi. Jenis penelitian deskriptif kualitatif menggunakan analisis stakeholder yaitu pemetaan dan pemahaman kekuasaan, posisi dan sudut pandang dari para stakeholder yang memiliki kepentingan dalam pembuatan kebijakan, atau mereka yang dipengaruhi oleh kebijakan tersebut serta menjadi bagian dari kebijakan dan analisis spasial untuk menentukan arahan zonasi pola ruang berdasarkan hasil skoring dan pembobotan dengan Sistem Informasi Geografis (SIG) berupa metode overlay. Berdasarkan matriks ITBX berhasil mengidentifikasi arahan zonasi aktivitas wisata di sempadan Sungai Bolango dengan mempertimbangkan aspek regulasi, lingkungan, dan sosial-ekonomi. Berdasarkan analisis stakeholder, ditemukan bahwa aktivitas wisata harus disesuaikan dengan ketentuan Rencana Tata Ruang Wilayah (RTRW) dan Peraturan Pemerintah No. 38 Tahun 2011 tentang Sungai, yang melarang pembangunan permanen di sempadan sungai. Persepsi stakeholder bervariasi, di mana pemerintah menekankan kepatuhan terhadap regulasi, akademisi dan LSM lebih berfokus pada dampak lingkungan, sementara masyarakat lokal dan pelaku usaha cenderung mendukung aktivitas yang meningkatkan pendapatan. Hasil analisis menggunakan matriks ITBX menunjukkan bahwa aktivitas seperti fotografi dan piknik dapat diizinkan secara penuh (I), sedangkan river tubing dan arung jeram diizinkan dengan pembatasan (T) atau syarat tertentu (B), seperti pengawasan keselamatan dan mitigasi dampak lingkungan. Sementara itu, aktivitas berisiko tinggi seperti snorkeling dan pembangunan cottage/villa tidak diizinkan (X) karena ketidaksesuaian dengan kondisi sungai dan potensi kerusakan ekosistem.

Abstract

Changes in river systems can significantly impact communities, particularly through property and infrastructure losses. This study investigates the fluvial landscape changes of the Bone River and their socio-economic implications in the Gorontalo region from a spatial perspective. The research employs multi-temporal Landsat satellite imagery from the Google Earth Engine platform to analyze environmental dynamics in the study area over the period 1995–2025. The imagery dataset includes Landsat 5 TM (May 5), Landsat 7 ETM+ (February 17), Landsat 8 OLI/TRS (October 19), and Landsat 9 (May 31). The results indicate notable changes in the river’s course. Evidence of erosion and sediment deposition was identified along the Bone River banks. The patterns reveal a tendency toward lateral migration of the river channel, horizontal shifts, and narrowing of downstream segments. Several natural cut-off points have formed, along with shifts in the main channel in the upstream and midstream segments during the 1995–2025 period. The lateral migration of the river channel reached up to 1.2 km northeastward (N60°E), primarily driven by anthropogenic activities such as traditional sand mining along the western banks and the conversion of riparian land into residential areas. From a socio-economic perspective, these river morphological changes pose potential threats to riverside infrastructure and may trigger land-use conflicts, particularly in areas with active sand mining operations

Abstract

This study aims to analyze the spatio-temporal dynamics of land cover for estimating the Urban Heat Island (UHI) phenomenon using Google Earth Engine (GEE) in Gorontalo City.Multi-temporal Landsat 5/7/8/9 data were processed in GEE to derive NDVI, emissivity, and Land Surface Temperature (LST). The UHI index was calculated using the statistical threshold formula UHI = Ts − (μ + 0.5α), where values of zero or below (≤0) indicate non-UHI areas, while positive values (>0) represent areas affected by UHI. A correlation analysis was performed between field temperature, LST, and NDVI. Temporally, Gorontalo City exhibits the expansion and intensification of UHI over the 30-year period. The most evident changes are the increased area of the 0–1 and 1–2 classes enveloping the urban area, while the 2–3 class emerges as localized hotspots corresponding to areas of highest density. LST increased from 21–56 °C (1995) to 26–58 °C (2025), while NDVI declined in the city center but remained high in the southern–western zones and near water bodies. The surface temperature exhibits a strong correlation with vegetation conditions and field temperature. The main drivers of these dynamics were the increase in impervious surface fractions (asphalt/concrete) and the reduction of vegetative cover, which decreased latent heat (evapotranspiration) and increased sensible heat.
