Abstract

Community Service Program (KKN) is a form of community service activities carried out by universities. In the KKN activities carried out in Giri Madia Village, Lingsar District, West Lombok Regency, groups of students and lecturers of Mataram University carried out various activities with the main target of utilizing home yards by making palm seedling houses. The purpose of implementing this KKN activity is to answer the problem of the large amount of vacant land in the yard that is not used and not maintained in Giri Madia village. So the KKN group conducted mentoring activities in the utilization of home yards for making palm seedling houses. There are 6 methods of activities carried out, namely (1) observation, (2) socialization, (3) practice, (4) distribution of plant seeds, (5) monitoring, and (6) evaluation. The results of this activity are expected to increase the knowledge and skills of the Giri Madia Village community regarding the utilization of home yards so that the community can still apply it. The results of the above activities show that this KKN activity has been able to help problems in terms of the utilization of home yards that are not utilized as one of the lands to cultivate quality palm seeds because palm plants that grow wild make people reluctant to cultivate them, it is also expected that the knowledge and skills of the community can increase and the results can help the economy of the Giri Madia Village community.

Abstract

Meninting Dam, constructed in 2019 in West Lombok Regency, is a newly built reservoir that is vulnerable to sedimentation caused by land erosion in its upstream catchment area. This study aims to estimate the erosion rate, sedimentation rate, and predicted service life of the Meninting Dam as a basis for early sediment management planning. Erosion was calculated using the Modified Universal Soil Loss Equation (MUSLE), while sedimentation was estimated using the Sediment Delivery Ratio (SDR) based on the Boyce (1975) method, integrated with spatial analysis using QGIS. The results show that the erosion rate in the Meninting Dam catchment area reaches 884,467.83 tons/year, producing a sedimentation rate of 40,526.39 m³/year and an estimated dam service life of approximately 45 years. These findings indicate that erosion-induced sedimentation poses a significant long-term risk to the storage capacity of the Meninting Dam and highlight the importance of early erosion control and sediment management strategies for newly constructed reservoirs.
