Abstract

Bendungan Meninting merupakan infrastruktur strategis yang memiliki potensi risiko tinggi apabila terjadi kegagalan struktur atau keruntuhan. Keruntuhan bendungan dapat mengakibatkan banjir bandang yang berdampak langsung terhadap keselamatan jiwa, kerusakan lingkungan, dan kerugian sosial ekonomi masyarakat di wilayah hilir. Kegiatan pengabdian ini bertujuan untuk meningkatkan kesiapsiagaan masyarakat melalui simulasi tanggap darurat keruntuhan Bendungan Meninting di Kabupaten Lombok Barat. Metode pelaksanaan kegiatan meliputi tahapan persiapan dan koordinasi dengan pemerintah desa dan BBWS Nusa Tenggara I, sosialisasi kebencanaan kepada masyarakat, pelaksanaan simulasi evakuasi darurat, serta evaluasi pasca kegiatan. Simulasi dilakukan dengan skenario keruntuhan bendungan saat muka air tinggi, melibatkan masyarakat, perangkat desa, relawan dan instansi terkait. Pengumpulan data dilakukan melalui observasi lapangan, kuesioner sebelum dan sesudah kegiatan, serta diskusi kelompok terfokus. Hasil kegiatan menunjukkan adanya peningkatan pemahaman masyarakat terhadap risiko keruntuhan bendungan, jalur evakuasi, titik kumpul, serta sistem peringatan dini. Masyarakat juga menunjukkan peningkatan respon cepat terhadap sirene peringatan dan kemampuan mengikuti prosedur evakuasi dengan lebih terorganisir. Secara keseluruhan, simulasi tanggap darurat terbukti efektif dalam meningkatkan pengetahuan, keterampilan, dan kesiapsiagaan masyarakat terhadap potensi bencana keruntuhan bendungan. Kegiatan ini direkomendasikan untuk dilaksanakan secara berkelanjutan dan terintegrasi dalam program desa Tangguh bencana guna membangun budaya sadar risiko di wilayah terdampak.

Abstract

The Mandalika Special Economic Zone (SEZ) is currently a leading destination not only in Lombok but also in Indonesia. The presence of the Mandalika Circuit as a MotoGP race venue, along with the beauty of the coastal landscape and other tourism potential, makes Mandalika a Super Priority Destination. The Mandalika SEZ is located in three river basins, namely Tebelo Ngolang and Balak. Behind the splendor of the Mandalika Circuit and other supporting infrastructure lies a series of flood data that hit the area, including the floods of January 30, 2021, and December 23, 2022. Based on these events, a study is needed to map the flood risk in the three watersheds and the Mandalika SEZ. This flood risk map can later serve as a basis for formulating policies and anticipatory measures for future flooding. The required data includes rainfall data, land use maps, topographic maps, land use maps, slope maps, and geological/soil type data. The data were then analyzed using a Geographic Information System (GIS) and then overlaid using the ArcGIS software program. Based on the overlay results and weighting of the supporting factors for flooding, flood vulnerability at the study location can be determined. The results showed that the Tebelo Watershed is divided into 3 categories, namely a moderately vulnerable area of 270.32 ha, a vulnerable area of 479.89 ha and a very vulnerable area in the downstream area of 85.44 ha. The Ngolang Watershed is divided into two categories dominated by a vulnerable area of 930.97 ha and a moderately vulnerable area of 568.68 ha. Meanwhile, the Balak Watershed is divided into two categories, namely a vulnerable area of 1,418.59 ha and a moderately vulnerable area of 1,243.53 ha

Abstract

Indonesia is an archipelagic country located between the Indian Ocean to the south and the Pacific Ocean to the north. As a consequence of this, during the rainy and transitional seasons, extreme weather occurs, especially in the southern coastal areas. According to data from the National Disaster Management Agency, in the last six years, more than 200 tidal waves and abrasion have hit the coastal areas of Indonesia. These conditions can lead to various disasters, particularly tidal flooding. Therefore, the development and design a wave height monitoring device as an early warning system for tidal flooding is necessary. This device is expected to play a vital role in disaster mitigation, because it can provide the information about the potential for tidal flooding based on the changes in wave height. The design of this device uses the LPD3806 encoder as a sensor and the nRF24L01 to send information to the monitoring station. Furthermore, running tests has been conducted and based on the results of the maximum distance test, information delivery can reach 800 meters in an open area with a maximum delay of 2 seconds. For sensor accuracy, a value of  99.7% was obtained, indicating the sensor has a small measurement error rate. On top of that, during field tests, the device demonstrated durability under bad weather, with no loss of data sent. This shows that this device can operate reliably under extreme weather environments.
