Abstract

The interaction of social-ecological systems in coastal villages often causes problems, ranging from decreasing ecological quality to social conflict. This research aims to determine the description of the social interaction system in the coastal area and to determine the description of the ecological system in the coastal area of Kuala Kaidipang Village, North Bolaang Mongondow Regency. The data used is secondary data obtained by direct observation. The research results show that the separation between social and ecosystem management causes a decline in small-scale fisheries production on the coast due to a decline in fish stocks. The decline in fish stocks is caused by overfishing, habitat degradation and pollution. Open access further exacerbates the problem of overfishing. Managers and stakeholders face difficulties in designing and implementing effective management solutions. As for social interaction, it can be seen from 2 aspects, namely close relations between residents, interaction with the natural environment and coastal activities. Meanwhile, the ecological system includes coastal ecological systems including marine biodiversity, mangrove ecosystems, human activities and sustainability.

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. Keywords: Soil conservation, Water, Gorontalo.
