Abstract

One of the efforts to overcome the clean water crisis in the archipelago, one of them is Merbau Island, is to make a simple technology that is used to accommodate excess water during the rainy season and next, the water can be utilized for various purposes when it has been needed. The technology is rainwater storage building (PAH). This community service activity was conducted by making a model of PAH building at one of the residents’ houses and conducting a counselling activity to residents in relation to both of calculation and planning of the PAH building, and also the importance of consuming clean water. The purposes of this community service are to give an understanding and increasing knowledge about the needed for rainwater harvesting technology so that daily clean water needs will be fulfilled by basic infrastructure of the ideal PAH system based on independent-communities. The volume of this rainwater reservoir is needed at 3 m3 (3,000 litres) from the roof area of 36 m2. This rainwater is used to meet the needs of drinking, cooking and washing of 15 litres/person/day. The number of residents in the house is 5 people. The results obtained from this activity are the construction of rainwater reservoirs with a volume of 1,000 litres with good and correct rainwater harvesting system equipment. Thus the lack of 2,000 litres of rainwater storage must be managed independently by the homeowner.

Abstract

Monitoring dan evaluasi kinerja Daerah Aliran Sungai (DAS) penting dilakukan untuk mengetahui pengelolaan DAS. Berhasil atau tidaknya pengelolaan DAS berkaitan dengan indikator kinerja kelestarian DAS yaitu kelestarian lingkungan yang meliputi tata air. Berdasarkan Lampiran Surat Keputusan Menteri Kehutanan tentang Pedoman Penyelenggaraan Pengelolaan DAS No P.61/Menhut-II/2014, bahan monitoring dan evaluasi kinerja Sub DAS dibagi menjadi lima kriteria, salah satunya yaitu kondisi tata air. Kondisi tata air dinilai berdasarkan parameter yang meliputi koefisien regim aliran, indeks penggunaan air, koefisien aliran tahunan, banjir. Tujuan penilitian ini adalah untuk menganalisis indikator kriteria klasifikasi Sub DAS Kampar kanan sehingga diketahui hasil klasifikasi parameter yang dikaji. Hasil penelitian menunjukkan Koefisien Regim Aliran (KRA) diklasifikasikan sangat rendah dengan nilai 10,769, artinya aliran sungai pada DAS relatif konstan baik pada musim banjir maupun kemarau. Indeks Penggunaan Air (IPA) diklasifikasikan sangat rendah dengan nilai 0,008, artinya DAS Kampar masih menghasilkan air untuk wilayah di hilirnya. Koefisien Aliran Tahunan (KAT) diklasifikasikan sangat tinggi dengan nilai 1,309, artinya curah hujan yang jatuh menjadi limpasan langsung dan tidak terserap ke dalam tanah. Banjir dikategorikan sangat tinggi dengan frekuensi kejadian 2 (dua) kali dalam 1 tahun, artinya fungsi tata air dari DAS tersebut sudah semakin terganggu sehingga perlu segera untuk direhabilitasi.

Abstract

The population from year to year always increases based on population statistics as ell as with the geographical and topographical conditions of different villages in Inuman District, resulting in the coverage of distribution network system services by SPAM at certain points not getting services and causing conditions where not all people who have access to the distribution network have received services. can be served. Three villages still have not received drinking water supply services by the Inuman District SPAM, namely Sigaruntang, Banjar Nan Tigo and Bedeng Sikuran villages. Based on these conditions, it is necessary to analyze how the hydraulic conditions of the existing network are and alternative alternatives for the development of distribution pipelines are needed to improve distribution services to the community. Collecting data in the form of information needed for processing the modeling of the Inuman SPAM distribution network such as elevation data of the study area, demographics, network maps, pipe data (pipe diameter and pipe length). The methods used in this research are population projection analysis, water demand analysis, distribution pipe network model simulation using EPANET 2.2 software in the form of hydraulic simulations in the form of head loss, flow velocity. From the results of this study, population growth estimates use the arithmetic method, the amount of water demand at peak hours in 2040 is 23,599 liters/second. Analysis of the distribution network development system using EPANET 2.2 with QPeak 23,599 liters/second there is no pressure below the pressure criteria.
