Abstract

The construction of the Meninting Dam located in West Lombok Regency, was motivated by the unequal supply of water on Lombok Island. The Meninting Dam was built with the aim of providing irrigation water to Sesaot, Penimbung, and Ketapang Irrigation Area. Apart from that, it is also to supply raw water needs and is used for electricity generation. In fulfilling these goals, it is necessary to carry out careful calculations and use water optimally in an effort to meet these needs. This research aims to obtain optimization results from water utilization with the objective function in the form of maximum profit with a decision variable in the form of optimal irrigated land area and to determine the annual benefit value from dam water use. Optimization analysis is carried out using program Solver in Microsoft Excel. In calculating water availability, Orong Atas AWLR data is used with an area comparison formula. Meanwhile, in calculating the need for irrigation water, several alternatives were tried based on the start of different planting seasons. Based on optimization calculations using Solver, the optimum area was obtained at 1065,29 ha in Sesaot Irrigation Area, 454 ha in Penimbung Irrigation Area, and 40 ha in Ketapang Irrigation Area with a planting intensity for each irrigation area of 300% and reliability of the reservoir at the November I planting season was 80,42%. The value of annual benefits obtained in one year from the productivity of paddy and secondary crops, raw water, and electricity is IDR 105.168.334.600,00.

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.

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

The Reban Batu irrigation area located in West Sumbawa Regency has experienced a decline in the performance of its irrigation system. Therefore, it is necessary to make efforts to improve the performance of the irrigation system by carrying out maintenance and rehabilitation, which is based on the results of the irrigation performance index assessment. The purpose of this study is to determine the irrigation system performance index in the Reban Batu irrigation area and the variables that affect irrigation performance. As for the irrigation system performance assessment, it can be based on the decree of PUPR No. 12/PRT/M/2015 and the MASSCOTE Method. The irrigation system performance assessment was carried out by direct surveys of the location and interviews with Water User Association (WUA) Farmers as beneficiaries and operational and maintenance (OM) officers as managers, resulting in a performance index based on the decree of PUPR 68.26% which was included in the category of underperforming and requiring attention. Meanwhile, based on the MASSCOTE method, the score is 2.69 or the level of service is in the poor category. Based on path analysis, the indicator variables of Irrigation Service (X1), WUA (X2), Human Resources of OM Officers  (X3), and the Modernization of OM (X4)together have a significant effect on the irrigation performance variable (Y) of 0.931 or 93.1%.

Abstract

River diversion is a procedure carried out prior to constructing a dam. It is conducted by diverting water from the main river so that the main dam construction work can be executed at a specifically dry area. In Meninting Dam, the diversion system consists of two main structures, namely cofferdam and diversion tunnel that is equipped with a navigation structure at the upstream part of the tunnel. During the construction, cofferdam experienced overtopping on June 17, 2022. The overtopping most likely occurred because of the diversion tunnel’s inability to divert the actual flood effectively during the construction. Therefore, this research aimed to analyse the effectiveness of Meninting Dam’s proposed diversion tunnel against design flood discharge for a return period of 25 years. The data used in this research were the updated version of the ones used to design the whole construction of Meninting Dam’s diversion system, while the flow conditions along the diversion tunnel were analysed using HEC-RAS. At the same time, the analysis was also carried out using the Level Pool Routing Method as a comparison. The analysis results show that the design flood discharge for a return period of 25 years in Meninting Dam Watershed is 265,62 m3/s. This causes the water level along the diversion tunnel reach el. +165,95 m above sea level. Taking into account that the cofferdam crest elevation is at +170,00 m above sea level, it could be concluded that Meninting Dam’s proposed diversion tunnel, which is 4 m wide and 4 m tall is able to divert the design flood discharge for a return period of 25 years effectively. The investigation results in Meninting Dam Watershed show that the main cause of the overtopping was heavy precipitation. This caused the increasing water level at the upstream part of the cofferdam that resulted to its inability to function properly, taking into account that it was still under construction when it occurred

Abstract

Final-year students of the Civil Engineering Department are the spearhead of the University of Mataram's output. They need to be provided with comprehensive academic knowledge and skills to enable them to adapt to a flexible workplace. This is especially true in the current era of drought, which is a significant concern, making it crucial to provide students with the efficient use of water for crop irrigation. Therefore, final-year students need to be encouraged to undertake field-level learning to complement their knowledge and skills before completing their studies. Therefore, it is necessary to mentor final-year students in the design and use of water-efficient drip irrigation systems at the field level for a specific period of time to improve their competency until they are able to use drip irrigation in agriculture. This activity aims to mentor final-year students in the design and use of drip irrigation systems at the dryland level in Pujut District, Central Lombok Regency. The mentoring activities include site preparation, network preparation, drip irrigation network testing, and the use of drip irrigation in the planting medium. The irrigation design uses ¾-inch and ½-inch PVC pipes, factory-made Netafim (NTF) drip pipes, a 600-liter water tank as the water source, and accessories. Students were mentored through the stages of creating a distribution network, designing a drip irrigation network, testing it, and implementing it on their planting areas. The mentoring program successfully guided four final-year students and local residents, and the students were able to construct a drip irrigation network on approximately one acre of land. The students have successfully implemented the drip irrigation system.

Abstract

Flooding is a recurrent hydrometeorological hazard that occurs when rainfall intensity exceeds river channel capacity within a watershed. In the Lombok River Basin, limited rain-gauge density hampers the detection of localized high-intensity rainfall that can trigger flood events. This study develops a satellite-based rainfall estimation model using Himawari-8 infrared Cloud Top Temperature (CTT) integrated with surface atmospheric parameters, including relative humidity (RH), zonal and meridional wind components (u and v), and surface air pressure (P). Hourly rainfall observations from 15 rain gauges were used for site-specific calibration during two major flood events (6 December 2021 and 17 June 2022). A local nonlinear exponential regression model was fitted for each station using the Non-Linear Least Squares (NLLS) method, and model performance was evaluated using R², Nash–Sutcliffe Efficiency (NSE), RMSE, and RSR. Results indicate that thermodynamic predictors, particularly CTT and RH, provide the strongest empirical relationships with rainfall variability, while wind components contribute weaker at the statistical level. Overall performance varied spatially across stations, reflecting local terrain and microclimate effects. The proposed framework supports improved rainfall characterization in tropical island basins and can be adapted to other regions with appropriate local calibration.
