Abstract

This community service activity was conducted in Dusun Nglengis through the Community Service Program under the guidance of one field supervisor and involved ten students. The activity aimed to support the community through business strengthening, home yard utilization, assistance in Quran learning activities, and support for posyandu services. The method used was Participatory Action Research through observation, joint planning with residents, program implementation, and evaluation. The participants included four small business owners, nine housewives managing home yards, fourteen active Quran learning students, and three posyandu cadres. The results showed that all targeted small businesses were successfully registered on Google Maps and provided with business banners, two simple planting models using used gallon containers were created, attendance in Quran learning activities increased from an average of eight to fourteen children per meeting, and posyandu services became more organized. This activity shows that simple programs designed from community needs can help strengthen the social and economic capacity of local residents.

Abstract

River channel realignment is a common river engineering measure to support regional development and flood mitigation; however, it may significantly alter river hydrological characteristics. This study aims to analyze changes in flood hydrographs resulting from the realignment of the New Kaliyasa River in the PLTU Cilacap area using the HEC-HMS hydrological model. Areal rainfall was determined using the Thiessen polygon method based on annual maximum daily rainfall data from nearby rainfall stations. Design rainfall was estimated through frequency analysis using several probability distributions, namely Normal, Log-Normal, Gumbel, and Log Pearson Type III, which were evaluated using the Chi-square and Smirnov–Kolmogorov goodness-of-fit tests. The results indicate that all tested distributions are acceptable; however, the Gumbel distribution was selected as the best-fit distribution due to its smallest maximum deviation value. The selected design rainfall was then transformed into hourly rainfall using the Alternating Block Method (ABM). Hydrological modeling with HEC-HMS was conducted to generate design flood hydrographs for various return periods. The simulation results show variations in peak discharge, time to peak, and runoff volume, reflecting the hydrological response of the Kaliyasa watershed after river channel realignment. This study demonstrates that HEC-HMS is effective in representing flood characteristics and can serve as a technical basis for evaluating river capacity and planning flood control measures in the PLTU Cilacap area.
