Abstract

The model for estimating groundwater availability for plants often overlooks the type of soil and the capacity of plants to absorb water from it. This study employs laboratory soil tests and statistical analyses to examine the relationship between various soil types in Pohuwato Regency and the variations in Groundwater Availability (KAT) levels for rice and corn plants. The results indicate that Andosol and Litosol are the soil types with the highest Field Capacity values in Pohuwato Regency, ranging from 331 mm to 403 mm. Meanwhile, Alluvial and Regosol soil types exhibit the lowest Permanent Wilting Point values in the Pohuwato Regency, ranging from 23 mm to 53 mm. The study results revealed a very high average correlation value of 0.907 between Field Capacity and the Permanent Wilting Point concerning the Groundwater Availability model. The research data, which includes soil characteristics and the Groundwater Availability model for rice and corn cultivation in Pohuwato Regency, can serve as a foundation for strategies that farmers can employ to enhance their future agricultural productivity.

Abstract

Use of state-owned land along river setbacks is a common phenomenon in densely populated urban areas. This study analyzes how communities utilize state land on the banks of the Jeneberang River and their motivations for settling there, which may trigger tenurial conflicts. The research was conducted in Bontoala and Taeng Villages, Pallangga Subdistrict, Gowa Regency, South Sulawesi, using a qualitative approach with in-depth interviews, field observations, and document review. Findings show that residents use the riparian zone for housing, small-scale enterprises (scrap collection, kiosks, livestock), and everyday social activities. The main motivations to reside in the area are economic factors (access to low-cost/abandoned land), locational advantages (proximity to Makassar and strategic for livelihoods), and socio-cultural factors (family inheritance, traditions, and community ties). However, this illegal use has implications for environmental degradation, declining river quality, and the emergence of potential horizontal and vertical conflicts over land tenure legality. The study underscores the need for regulatory measures and sustained public outreach to prevent conflict escalation in river setback areas.

Abstract

Maleo (Macrocephalon maleo), a unique Sulawesi endemic bird, is threatened by habitat loss. This study aims to analyse changes in maleo habitat areas in Sulawesi using spatial data and propose effective conservation measures. Spatial data in the form of maleo home range maps (IUCN) were used for overlay analysis. The results of the overlay analysis were compared with land cover data to identify changes in maleo habitat area. Of the total area of approximately 884,040 hectares, 14.13% or 124,887.63 hectares have been converted to agricultural land. The construction of new settlements has affected 0.46% or 4,087.5 hectares of the habitat. In addition, plantations have occupied 2.82% or 24,965.92 hectares of the maleo habitat area. Changes to maleo habitat areas in Gorontalo are significant, with agricultural land conversion, settlement development, and plantations being the main threats. Effective conservation efforts should focus on habitat restoration, law enforcement, community education, and the development of environmentally friendly economic alternatives.

Abstract

This research examines ethics and environmental policies in urban management across various countries. The study shows that rapid urbanization and environmental issues, such as clean water shortages and poor sanitation, have a negative impact on public health. The author identifies knowledge gaps in the integration of interdisciplinary approaches to achieve holistic sustainability solutions. The article highlights various regenerative approaches in environmental management, including circular economy and regenerative tourism, as solutions to address environmental and social challenges. The findings of this research indicate that active participation of local communities and improvements in infrastructure, such as clean water and sanitation, significantly enhance public health and environmental sustainability. The implications of this research emphasize the importance of cross-sector collaboration and regenerative approaches in supporting urban sustainability and reducing environmental and social risks

Abstract

This study analyzes the impact of income levels on the number of poor people in Gorontalo City, which, despite experiencing economic growth, still faces significant poverty issues. Gorontalo City heavily relies on the agriculture and fisheries sectors, which are vulnerable to climate change and market fluctuations, causing the income of the majority of its population to remain low and unstable. Previous studies have shown that although income has increased, high social and economic disparities have exacerbated poverty. In this study, we used simple linear regression analysis, which revealed a moderate relationship between income levels and the number of poor people, although the regression model has a low explanatory power (R-squared of 0.2160). The results indicate that, despite income growth, income inequality remains the primary factor contributing to the high poverty rate. The implications of these findings highlight the need for policies that focus more on income redistribution and the empowerment of the informal sector to reduce social inequality and improve the well-being of the people in Gorontalo sustainably

Abstract

The development of Limboto Lake  Site as the pilot area of Gorontalo Geopark is one step  in rescuing the lake. This research aims to analyzed  the vegetation structure, estimate biomass, and assess the carbon stock value of the vegetatio at the Limboto Lake site. This study employed a purposive sampling method. Important Value Index, a measure used to evaluate plant vegetation structure, was calculated based on Realtive Density, Relative Dominance, and Relative Frequency values. Biomass estimation and carbon stock assessment were conducted using allometric equations. The study’s finding showed that the vegetation surrounding Soekarno's landing area exhibited the highest IVI (sawlogs) scores for Swietenia mahagoni tree at 82.86%, Leucaena leucocephala saplings at 79.56%, and Manihot esculenta seedlings at 46.33%. Leucaena leucocephala consistently achieved the highest IVI score within the Limboto Lake area with a score as high as 76.90%, followed by Leucaena leucocephala on the sapling level with a score as high as 70.03%, and Nauclea orientalis on the seedling level with a score as high as 53.06%. Swietenia mahagoni, Samanea saman, and Leucaena leucocephala are three species with stems that predominate at the sawlog level and sapling, and these stems have high carbon absorption values.
