Abstract

Flood disasters in Kuta Village, Central Lombok Regency, are caused by high rainfall intensity, sedimentation, land-use changes, and low public awareness of river conservation. This study evaluates flood mitigation strategies for the Tabelo River through structural and non-structural approach. Hydrological analysis indicates that the river’s cross section is inadequate to handle flood discharge, leading to frequent overflows. Structural measures include sediment dredging to a depth of 1,45 m and constructing 4 m high embankments. Hydraulic modeling using HEC-RAS support these interventions to reduce flooding. Non-structural measures involve community outreach on riverbank regulations based on Ministerial Regulations No. 28 of 2015. This initiative aims to increase public awareness, prevent illegal riverbank constructions, and promote sustainable river management. The enforcement of riverbank regulations is expected to reduce flood risks, improve water quality, and minimize erosion and sedimentation. Additionally, educational posters have been developed to reinforce awareness of flood control and river construction. Integrating structural and non-structural strategies is crucial to mitigating floods and fostering environmental responsibility in Kuta Village.

Abstract

Selengen Village is one of the villages in North Lombok Regency that always experiences drought and lack of clean water every year. The problem of clean water availability is caused by limited water sources on the surface. The frequency of rainwater in Selengen Village is very small and with very low intensity. In order to meet the need for clean water, the community has to pay additional costs to buy clean water or wait for a drop from the government. The Selengan Village community has limited information regarding simple methods that can be used to collect clean water sourced from rainwater. The method used to introduce rainwater capture as a source of clean water is to provide direct outreach to the Selengen Village community about rainwater storage in the form of ABSAH (Artificial Aquifer for Rainwater Savings). The ABSAH method can be done individually or in groups. The socialization was carried out at the Panggung Barat Hamlet office involving the community consisting of farmer groups, community leaders, youth organizations and housewives. The result of the socialization regarding the introduction of artificial rainwater aquifers is the high desire of the community to create rainwater storage, either independently/individually or in groups. In the process of making it, the community hopes to get assistance from the implementation team so that the calculation of the storage volume is in accordance with the volume of water used. Apart from that, the community also hopes to be given drawings of storage designs, installations for collecting water from the roofs of houses and designs of distribution networks to people's homes.
