Abstract

The Tampanombo area, Tojo Una-Una Regency, Central Sulawesi Province, is composed of ultramafic rocks that have undergone intensive serpentinization due to interactions between primary silicate minerals and hydrothermal fluids. This study aims to examine the paragenesis of serpentine minerals in ultramafic rocks using petrographic, geochemical, and electron microscopy approaches. The methods employed include thin-section petrographic analysis, XRF, and SEM-EDS. Petrographic observations reveal characteristic serpentinization textures, including mesh texture as the initial product of olivine hydration, bastite texture formed by pyroxene replacement, and hourglass texture indicating serpentine recrystallization. Interlocking and interpenetrating textures in antigorite were also observed, indicating mutually penetrating crystal growth associated with increasing temperature and pressure during advanced metamorphic stages. The presence of type-1, type-2, and type-3 veins suggests multiple phases of fluid circulation during rock evolution. XRF analysis indicates high MgO content along with variations in SiO₂, Fe₂O₃, and LOI, reflecting different degrees of serpentinization among samples. SEM-EDS data confirm the dominance of Mg, Si, and O as the main constituent elements of serpentine minerals, as well as the presence of Fe associated with magnetite formation. Based on textural and geochemical data, the paragenesis of serpentine minerals in the study area includes three main subprocesses: hydration, serpentine recrystallization, and deserpentinization (dehydration) related to prograde metamorphism.

Abstract

Mangrove forests provide essential ecological, economic, and social benefits, including coastal protection, habitat provision, and support for local livelihoods. However, mangrove ecosystems in Ponelo Kepulauan District, North Gorontalo Regency, have experienced significant degradation due to land conversion, illegal logging, coastal abrasion, climate change, and inadequate management. This study aimed to formulate an appropriate mangrove forest rehabilitation strategy based on internal and external factors affecting rehabilitation efforts. A descriptive quantitative approach supported by qualitative data was employed through field observations, interviews with coastal communities and village government officials, and SWOT analysis using the Internal Factor Analysis Summary (IFAS) and External Factor Analysis Summary (EFAS) matrices. The results indicate that the rehabilitation strategy is positioned in Quadrant I (Strengths–Opportunities), with an IFAS score of 0.95 and an EFAS score of 1.15, indicating strong internal conditions supported by favorable external opportunities. The recommended strategy emphasizes optimizing the ecological and economic potential of mangroves, strengthening collaboration among local communities, government agencies, universities, and non-governmental organizations, promoting community-based ecotourism, enhancing environmental education, and improving post-planting management and institutional capacity. These integrated strategies are expected to enhance the effectiveness and sustainability of mangrove rehabilitation while supporting environmental conservation and improving the welfare of coastal communities in Ponelo Kepulauan District.

Abstract

The spatial distribution of surface erosion on corn fields in Boalemo Regency, Gorontalo Province is a significant concern. Boalemo Regency is known for its corn production, but the land clearing for corn cultivation, especially on steep slopes, has led to land degradation, triggering floods and landslides. This study aims to examine the spatial distribution of surface erosion on corn agricultural land in Boalemo Regency, covering all corn plantations in an area of 181,672.83 hectares. The RUSLE (Revised USLE) method was used to analyze soil erosion. The analysis of surface erosion levels was conducted based on the stages of corn planting, including the land preparation and planting stages. The results indicated that the total erosion during the land preparation stage was 2474870411 tons per year, while during the corn planting stage, it was 1150961410 tons per year. The level of erosion was found to be very severe, covering an area of 46706.92 hectares (25.71%) during the land preparation stage and 33852.80 hectares (18.63%) during the planting stage.
