Abstract

Sediment deposition is the main problem in the continuity of dam operations. Sustainable operation of dam can be maintained by dredging sediment deposited at the bottom of the impounding area. Because of the considerable costs and the lack of economic value of dam deposited sediment, dredging is carried out only when the serious sedimentation problem occurs. This research aims to analyse samples of sediment taken from various depths of Batujai Dam and to compare them with the pottery materials of Balibe Hill. Compositions of deposited sediment were analyzed to determine its potential as an alternative additional material used in pottery making. Comparisons were made based on the results of sieving analysis of material from both sources. The results show that the percentage of fine-grain material of Balibe Hill, especially grains with a diameter of ≤ 0.18 mm, is closer to the percentage of deposited sediment of Batujai Dam at an elevation of 92.5 masl and an elevation of 90.0 masl, while the percentage of coarse-grain material with a diameter of ≥ 3.35 mm is closer to the percentage of deposited sediment at an elevation of 87.5 masl. Gradation analysis indicates that composition of deposited sediment of Batujai Dam in sand grain classes can be engineered to some extent to make them closely identical to the composition of Balibe Hill materials so that it can be used as a mixture in pottery making.

Abstract

Candikusuma Beach in Bali has experienced significant erosion since 2009, threatening public facilities, including a mosque in Candikusuma village. This issue is critical as it affects a coastal fishing community. To mitigate the erosion, a revetment structure using concrete block armor is proposed. This revetment aims to protect the coastal cliff from wave forces and prevent further erosion. The planning process begins with analyzing bathymetric and topographic data to assess land and sea conditions. Tidal analysis determines key water elevations, while wind data is used to calculate maximum and average wind speeds and directions. Wave hindcasting, based on wind data and effective fetch length, provides estimates of wave height and period. Shoreline changes are evaluated by comparing satellite imagery from 2003 and bathymetric surveys from 2012, revealing an average shoreline retreat of 21.70 meters over nine years. The design of the revetment includes a crest elevation of +3.70 meters MSL, constructed on a base at -0.5 meters MSL. The concrete foundation extends to a depth of -1.5 meters MSL. Hindcasting results show maximum wave heights of 1.21 to 1.50 meters from the southwest, with an average wave height of 0.01 to 0.30 meters from the south. The design wave height for a 25-year return period is 1.37 meters with a period of 4.58 seconds, resulting in a wave height of 1.31 meters at a depth of 2 meters. The estimated budget for the 200-meter-long revetment is Rp. 7,778,174,000.

Abstract

The Gumantar Village community is a community located in the hills with terraced and sloping village conditions. Most of the community has yards and gardens, although not very large with terraced land conditions. The water source of the Gumantar Village Community comes from the upstream hillsides, with the number of hamlets as many as 16 hamlets with a population of around 2000 people and most of them are field farmers. Considering the potential of the surrounding land which is very large and in the form of terraces, it is necessary to provide counseling to the community on how to utilize limited water sources for farming activities with a drip irrigation system. To help the community, counseling is needed so that the community quickly understands the drip irrigation system. This community service aims to provide efficient irrigation counseling, namely drip irrigation, to encourage farming to be carried out around the yard. The community service consists of location survey activities, counseling, discussion and question and answer sessions, and evaluation. This community service has succeeded in providing counseling to 35 people consisting of housewives and fathers, as well as young people from the Dasan Tereng Hamlet mosque. Participants have gained knowledge about drip irrigation and obtained examples of the use of drip irrigation in yards and dry land, so that people are able to utilize limited water in the dry season for agricultural purposes in their yards

Abstract

Masyarakat Desa Gumantar merupakan kondisi perkampungan berterasering dan berlereng, sebagian besar Masyarakat memiliki lahan pekarangan yang belum dimanfaatkan. Desa Gumantar berasal dari dilereng perbukitan dengan jumlah dusun yang ada sebanyak 16 dan sebagian besar masyarakatya sebagai petani ladang. Memperhatikan potensi lahan pekarangan yang ada belum dimanfaatkan optimal, maka perlu disentuh dengan pemanfaatan lahan untuk peresapan air dimusim hujan melalui penyuluhan Biopori, dengan tujuan membantu masyarakat agar dapat berperan aktif dalam pelestarian lingkungan. Pengabdian terdiri dari kegiatan survey lokasi, penyuluhan, diskusi dan tanya jawab serta evaluasi. Pengabdian ini telah berhasil memberi penyuluhkan pada 30 masyarakat dan pemuda remaja masjid Dusun Dasan tereng. Peserta telah memperoleh pengetahuan tentang resapan Biopori dengan contoh cara pemasangannya pada lahan pekarangan.
