Abstract

Penelitian memproyeksikan penduduk Kota Banjarmasin dan kebutuhan air Kota Banjarmasin dari tahun 2014 hingga 20 tahun ke depan lalu dibandingkan kapasitas intake yang ada memenuhi kebutuhan di tahun mendatang.Dalam memproyeksikan pertumbuhan penduduk Kota Banjarmasin menggunakan 5 macam metode, yaitu metode aritmatika, metode geometrik, metode regresi linier, metode eksponensial dan metode logaritmik. Metode yang paling tepat untuk memproyeksikan pertumbuhan penduduk yaitu yang mempunyai nilai standar deviasi yang paling rendah dan nilai korelasi yang paling mendekati 1. Kebutuhan air di hitung dengan faktor kebutuhan air rata – rata, faktor kebutuhan air hari maksimum, dan kebutuhan air jam puncak. Membandingkan kapasitas intake yang ada dengan proyeksi kebutuhan air.Proyeksi penduduk Kota Banjarmasin menggunakan metode geometrik karena mempunyai nilai standar deviasi paling rendah dari metode yang lain dan nilai korelasi yang mendekati 1. Kapasitas intake yang dimiliki PDAM Bandarmasih cukup untuk mencakupi proyeksi kebutuhan air bersih Kota Banjarmasin hingga tahun 2033, namun kapasitas intake masih belum mampu untuk memenuhi kebutuhan air bersih jam puncak

Abstract

Clean water is one of the most essential needs for humans because all human activities in various aspects of life require clean water. Kapuas Regency has 17 sub-districts and has a population of around 410,446 people based on BPS data in 2020. The purpose of this paper is to determine the amount of clean water needed in Kapuas Regency to serve the needs of the community in the future. The need for clean water for the residents of Kapuas Regency is supplied by PDAM Kapuas, with two intakes located in Selat Sub-District and Mostkau Village. However, the two intakes cannot meet the clean water needs of the population of Kapuas Regency, which is increasing every year. So it is planned to build a new intake so that the clean water needs of the residents of Kapuas Regency can be met. The analytical method used to calculate population projections is the Geometric Method. The geometric method is used to obtain information on long-term development planning obtained from BPS (Central Bureau of Statistics) Kapuas Regency. The results of the geometric method will be known to predict the population in the next few years so that it can also be seen the amount of clean water needed to determine additional raw water sources in Kapuas Regency. The water demand analysis research that has been carried out shows that Kapuas Regency, which has a population of 410,446 people who have a total non-domestic water need in 2020 is1.006.113 liters/day, and the total amount of household and urban water needs is 63,538,127 liters/day. The laboratory tests and direct observations in the field showed that the construction of the new intake selected was in the village of Palangkai. Palangkai Village has a more strategic location because it is included in the freshwater category, namely bypH 6-9 (PP No. 82 of 2001) with a result pH calculation is 6.1, which is closer to the standard than Sei Asam village, which has a pH of 5.1.

Abstract

The design of water structures in rivers is very necessary to be able to manage rivers. Water structures, for example dams and weirs can be selected to manage watersheds. This study aims to evaluate the Tapin Dam spillway. The analytical method used is in the form of hydrological analysis and the design of the main building and spillway accessories. Hydrological analysis used with analysis of the frequency of rain data. Calculation of design flood discharge using the Melchior method. Spillway hydraulic analysis used the USBR Small Dams method. The data used is from secondary data. Data in the form of rain data at the nearest station, dam technical data and topography. The results of hydrological and hydraulics analysis calculations, based on data analysis for 15 years at the Bungur Rain Station using the Gumber method, the 100 year return period design rain is 167.56 m3/sec. The peak Q calculation using the Melchior method for a 100 year return period is 417.15 m3/s, for a Tc concentration time of 11.86 hours. Based on the above results, the second conclusion from this study is that the hydraulic analysis obtained a discharge curve after a spillway, with an elevation of 147.5 m, a flow height above the crest as high as 2.00 m with a discharge of 165.20 m3/s.
