Abstract

The process of evaluating land's suitability for a particular use, such as finding prospective new land for rice field is known as land evaluation. The purpose of this study was to determine the characteristics, the quality, and the suitability of land parametrically for the development of rice field. This research took place in Moliliulo, Tangga Barito Village, Dulupi District, Boalemo Regency, from March to August 2022. This research used a detailed level survey method where the variables observed were land characteristics in the form of physical properties, and then the chemical properties were analyzed in the laboratory. Furthermore, an analysis of the characteristics and suitability of land for rice field was carried out using a parametric approach. The results of this study indicated that the characteristics and quality of the land in the study area varied greatly from low to high category, starting from climate, land, and soil nutrient availability factors. The research location has 4 land suitability classes for rice field (Oryza sativa L.), namely class 1 (excellent) with an area of 17.52 ha (2.15%), class 2 (good) with an area of 3.08 ha (0. 38%), class 3 (sufficient) with an area of 710.44 ha (87.15%), and class 4 (poor) with an area of 58.15 ha (7.13%).

Abstract

Background: The Maleo (Macrocephalon maleo) is a Sulawesi-endemic bird with high conservation concern due to habitat degradation and population decline. The Panua Nature Reserve is a key Maleo habitat in Gorontalo Province, yet lacks updated data on habitat use and distribution patterns. This study aims to analyze Maleo presence in nesting grounds, evaluate habitat utilization, predict its distribution, and provide conservation recommendations. Methods: The research used direct surveys via camera traps and spatial modeling using the Maximum Entropy (MaxEnt) algorithm. Data were collected over five months, and analysis included the Relative Abundance Index (RAI) and occupancy modeling to assess habitat suitability and species detection. Finding: Maleo nesting pairs increased by 68.52% from 2022 to 2023. The species exhibited bimodal daily activity (peaks at 06:00–09:00 and 16:00–18:00), with habitat preference for geothermal zones and coastal forests. The RAI was 9.33%, and occupancy rate was estimated at 55%. MaxEnt modeling revealed 7,544.78 ha of highly suitable habitat, concentrated in grids N10, J13, K14, and M09, with an AUC of 0.826, indicating high predictive accuracy. Conclusion: Maleo birds in Panua Nature Reserve are showing a positive nesting trend. However, habitat fragmentation and human activities continue to threaten their sustainability. Strategic management is needed to maintain habitat integrity and support species conservation. Novelty/Originality of this article: This study integrates field-based camera trap data with predictive spatial modeling to provide a comprehensive habitat suitability analysis for the endangered Maleo in Panua Nature Reserve—an approach not yet applied in this location. The findings offer actionable conservation insights and prioritize critical zones for protection.

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

This study aims to analyze changes in land cover over a specific period, focusing on the influencing factors and their impacts on the Biyonga Sub-Watershed ecosystem. The method used in this research is a combination of descriptive research method with spatial analysis interpretation approach and field survey. The research findings indicate that spatial analysis of land cover in the Biyonga Sub-Watershed revealed nine land cover classes, such as forest, shrubland, settlements, and agriculture. Land use change patterns were evaluated by overlaying land cover maps from 1990 to 2020. Significant changes in land cover occurred between 1990 and 2000, where secondary dryland forest cover changed to shrubland covering an area of 2,299.98 hectares. For the period 2000-2011, it was found that there was a loss of primary forest cover totaling 2097.27 hectares, which transitioned into secondary dry land forest and shrubland. Other changes included paddy fields transitioning into settlements and dry land agriculture, and dry land agriculture transitioning into settlements. From 2011 to 2020, there was an increase in the area of secondary forest cover and transitions from shrubland and dry land agriculture to secondary forest as well as mixed dry land agriculture.

Abstract

Gorontalo Province has topography in the form of lowlands to highlands which is shaped like a basin and most of Gorontalo Province is a water catchment area. One of the rivers with quite high sedimentation levels is the Alo River. To avoid more severe damage, technical conservation steps need to be taken, one of which is by building serial and continuous Check Dams. This research aims to determine erosion and sedimentation control and its effectiveness in the Alo watershed. The research method used was a direct survey method at the activity location, interviews with related agencies and people who were active at the location, then analysis was carried out. The stages begin with collecting primary data, secondary data. The data analysis used is using the Smith and Wischmeier (1978) equation known as the Universal Soil Loss Equation (USLE) A = R x K x LS x C x P. The results of the research show that the activities The construction of the Check Dam was carried out in 2021 by the Environment and Forestry Service of Gorontalo Province through KPH VI Gorontalo which is located in Buhu Village, Gorontalo Regency. The results of studies in the field show that the width of the Alo River is narrowing and experiencing shallowing, marked by the appearance of deltas at several points. On average, the width of the Alo river is only around 3-4 meters with a depth of around 10-15 cm. The conclusion of this research is 4. The Check Dam built by DLHK Gorontalo Province through KPH VI does not function well in dealing with erosion and sedimentation that enters the Alok River due to lack of maintenance and involvement of the local community.

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 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
