Abstract

Landslides often occur in Seki village. This study aims to mapping the level of landslide disaster vulnerability in Seki village, South Galela Distric. Mapping landslide-prone areas is a mitigation narrative and a reference for consideration of future regional development. This study uses the Slope Morphology method (SMORPH). Mapping using the slope tools for slope slopes and the curvature tools for slope shapes. Data analysis was carried out overlay of slope and slope shapes maps using ArcGIS 10.8 software to obtain a map of the landslide vulnerability in Seki village. Results of the research on the convex slope shape have the highest area compared to concave and flat forms, which is 1540.49 ha or 65.44%. Seki village area can be divided into two segments based on distribution of slope slopes. The slope of 0-8% dominates the central area to the northern region, the southern part is dominated by slopes of 8-15% and 15-25%. Landslide vulnerability in Seki village for the central to northern region is dominated by the very low category, the southern region is dominated by a low level of vulnerability. Level of medium and high landslide vulnerability is spread across the southern and northern regions. The distribution area of medium and high landslide vulnerability needs to be a serious concern, especially the village government and the people of Seki village.

Abstract

Juanga Village, South Morotai District, Morotai Island Regency, is one of the areas that is very vulnerable to coastal erosion, this is due to the high sea waves that often occur. Community service activities aim to educate the local community about the importance of planting mangroves as an effort to mitigate the coastal erosion disaster that occurred in Juanga Village. Community service starts from identifying problems that occur, then conducting outreach to the community and carrying out mangrove planting actions in designated areas involving KKNT students at Hein Namotemo University. The result of Community Service is that the community can be educated to continue to maintain natural balance by planting coastal vegetation that can withstand the rate of abrasion, one of which is mangroves because mangrove vegetation is important vegetation for the sustainability of marine biota and as a coast guard from abrasion. It is hoped that with this activity the people of Juanga Village can increase their knowledge and carry out sustainable planting.
