Abstract

Determination of irrigation channel dimensions is determined by the number of consumptive use values that are empirically determined by the potential evapotranspiration value (ETo). Due to the limited lysimeter measurement data, the ETo value is usually approached by an empirical method using weather data input. The recognized standard method for its reliability and can be used universally in determining ETo values is the FAO Penman-Monteith method. However, the use of this method is only possible if complete weather data is available. This study modified the simplest ETo calculation method, the Thornthwaite method and the evaporation pan method to obtain ETo values as accurate as FAO PM resulted. Callibrations are made by finding the correction number to get the best results shown by the high of correlation number and the efficiency index value. The results obtained are for the area with limited weather data condition, the Thornthwaite method both before and after calibration has better accuracy than the evaporation pan method. While the calibration carried out successfully increased the correlation number and efficiency index of both methods significantly. The results of the two calibrated methods, the Thornthwaite method provides better and satisfactory performance with a ratio between 0.86 and 0.89 and the efficiency index reaches 0.78.

Abstract

Land use change is one of the factors that affect changes in flood discharge in watersheds. Currently, the Mandalika Resort area has been designated as a Special Economic Zone (SEZ) so that large-scale development occurs in the Mandalika area with an area of 1,035.67 Ha. The purpose of this study was to determine the effect of changes in land use at the Mandalika resort on flood discharge in the watersheds in the Mandalika SEZ, namely the Balak, Ngolang and Tabelo watersheds. The data used are rainfall data, watershed maps and land use. Rainfall data is needed for analysis of hourly rainfall distribution, the method used is the Alternating Block Method (ABM). Land use maps and their changes are used to obtain Curve Number (CN) values. These parameters are used as input into the HEC-HMS software. The results of the analysis show that changes in land use have caused the CN value of the Balak watershed to increase by 1,33% in 2030 and increase by 3,72% in 2045, the CN value of the Ngolang watershed increase by 3,24% in 2030 and increase by 6,49% in 2045 and the value of the CN DAS Tableo will increase by 0,12% in 2030 and increase by 0,59% in 2045. Changes in land use have also resulted in an increase in flood discharge at various return periods. In the Balak watershed it will increase by an average of 1,76% in 2030 and 4,94% in 2045, the flood discharge in the Ngolang watershed will increase by an average of 4,00% in 2030 and 8,67% in 2045 and in the Tebelo watershed it will increase by an average 0,17% in 2030 and 0,79% in 2045.

Abstract

The biggest water demand is in the agricultural sector. This great need is caused by the irrigation system with continuous inundation (conventional). One of the water-saving irrigation methods is the System of Rice Intensification (SRI) method. The SRI method of giving water is done intermittently. One of the obstacles to the application of the SRI method is a continuous water source. The dam is one of the water sources whose water availability is relatively easy to manage, making it suitable for irrigation applications using the SRI method. This study aims to analyze the provision of irrigation water for SRI and conventional systems at the Meninting Dam and its effect on the area of irrigation services. In this study, an analysis of water availability was carried out using awlr data, an analysis of irrigation water requirements using the conventional method and the SRI method. Reservoir simulation analysis is used to determine the area that can be irrigated, planting intensity and reservoir reliability. The results for the conventional method of irrigated area that can be served are 1,559 ha with a planting intensity of 300% and a reservoir reliability of 95.83%. At the same intensity and reliability as the conventional method, the SRI method can irrigate 1,980 ha of irrigation area, so using the SRI method can increase the service area by 421 ha or can increase the service area by 27%.

Abstract

Water is the main need for humans to fulfill life's needs. For humans, clean water is absolutely necessary for various needs, namely for bathing, washing, cooking and so on. There are several water sources that humans can use, including springs, river water and ground water. Water sourced from springs and groundwater is relatively better quality, while water sourced from rivers requires prior management. Gegerung Village is one of the villages in Lingsar District, West Lombok Regency. Some of the people of Gegerung Village depend on their water needs from the Meninting River which passes through their area. The existing water supply system is by tapping directly from the river. Before being distributed, the water first passes through a filtering system so that the water becomes clearer. However, the current condition of the water filtration system cannot function properly so that the distributed water remains dirty. To get clean water again, it is necessary to revitalize the water filtration system. Revitalization is an effort to restore the function of the water filtration system by cleaning and replacing the filter media material. The results of the tests carried out show that there is an improvement in water quality after replacing the filtering media

Abstract

Ecodrainage is a concept for managing rainwater and runoff in urban drainage systems which aims to allow as much water as possible to be absorbed into the ground. During the rainy season, the Grand Muslim Residential area often experiences flooding. One alternative solution is the application of ecodrainage in the form of retention pond and bioretention. This research aims to determine the effectiveness of implementing retention pond and bioretention in reducing the amount of run-off flow. From the results of the analysis it was found that the application of retention ponds could reduce the volume of runoff by 16.25% with a reduction volume of 660 m3 against the incoming flood volume of 4,183.98 m3 originating from Blocks A, B, C, D and E.. Meanwhile the application Bioretention has an efficiency of 1.83% with a reduced discharge of 58.29 lt/sec against the overall housing discharge of 3.193.50 lt/sec.

Abstract

Desa Setanggor dilewati oleh sebuah sungai yaitu Sungai Berampes yang dapat dimanfaatkan sebagai penyediaan air di musim kering melalui pengolahan kualitas air. Sebagian besar masyarakat di Desa Setanggor Kecamatan Praya Barat belum memanfaatkan dan terlayani oleh jaringan air bersih PDAM sehingga memanfaatkan air dari sumur bor komunal sebagai penghasil air baku sehari-hari. Namun, karena beberapa keterbatasan teknis dan non-teknis menyebabkan ketidakcukupan untuk pemenuhan kebutuhan sehari-hari masyarakat sekitar. Akibatnya sebagian masyarakat mengalami kekurangan air bersih terutama di masa kemarau panjang. Hasil instalasi dan uji fungsi alat menggunakan sampel air dari sungai Berampes menghasilkan 4 dari 5 nilai parameter kualitas air yang sesuai dengan standar dari Permenkes 32/2017, kecuali temperatur. Oleh karena itu, disarankan lokasi dan waktu pengambilan sampel air serta perlakuan pra-pengujian mendapatkan perhatian dan porsi khusus dalam proses pengujian, selain jenis material gradasi partikel penyaringnya.

Abstract

Selaparang and Mataram Districts are two of the six districts in the Mataram City area that experience changes in land use every year. This change can affect the absorption capacity of groundwater in the area to decrease so that if there is rain with a fairly high intensity, it can cause water to overflow to the surface and inundate the area. This study was conducted to determine the runoff discharge that occurred due to changes in land use that occurred in 2013, 2018, and 2023, and to compare the runoff discharge in 2023 with the runoff discharge based on the Regional Spatial Plan of Selaparang and Mataram Districts in 2011-2031. The initial stage in this study was to collect several secondary data such as rainfall data, land use based on the regional spatial plan, and others that can be obtained from related agencies. After that, the next stage is the delineation of the catchment area and land use analysis with the help of ArcGis and Google Earth software, as well as runoff discharge analysis. The results of the analysis show that the percentage increase in runoff discharge that occurred in Selaparang District in 2013-2018, 2018-2023, and 2013-2023 was 2.21%, 1.40%, and 3.64%, respectively. Meanwhile, the percentage increase in runoff discharge in Mataram District in 2013-2018, 2018-2023, and 2013-2023 was 2.43%, 0.73%, and 3.18%, respectively. Based on this, it can be concluded that the reduction in green land area and the increase in built-up land area each year will cause an increase in the runoff coefficient value, so that the runoff discharge that occurs in Selaparang and Mataram Districts also increases every year.
