Clean water is a basic necessity for daily life. Clean water helps people maintain their daily lives in case of domestic activities. If using unclean water, it will be harmful to the health because water is the medium that transports chemicals and bacteria, viruses, parasites causing diseases that are not visible to the naked eyes. According to statistics, Our country still has many places where the quality of water supply is not ensured for daily life, especially in mountainous, frontier areas and places where the terrain is difficult and lacks of facilities. The water used for living in the northwestern region in general and the Ta Vai stream’s basin in Ha Giang province in particular is taken from rivers and streams that have not been treated or have been processed but the water quality is not guaranteed for living. Therefore, a study on the construction of the treatment model of Ta Vai spring water in Ha Giang province by using membrane technology combined with integrated filter materials for water supply is essential. The research shows that the water treatment model in Ta Vai stream by using membrane technology combined with integrated filter materials has completely treated water as reaching the quality of QCVN 02: 2009 / BYT - National technical regulation on domestic water quality.

The Impact

Despite Bali’s dependency on tourism, concerns over the impact of tourism on water scarcity are increasing. The objective of this study is to analyze the clean water demand related to tourism growth and compare them with the available clean water supply. This study suggested that tourism water demand has increased by 20.8 million m3 (295%) from 1988 to 2013. Sixty-eight percent of the increase was concentrated in Badung Regency, where the tourism water demand ratio has increased from 31% to 46%. The study also suggested that rapid population growth has caused an increase in domestic water demand by 48.3 million m3 (48%). This study also shows that the capacity of clean water supply in Bali has increased significantly to meet these demands and the water supply coverage of domestic water demand has increased significantly from 13% in 1988 to 53% in 2013. The water supply coverage of tourism demand varies from year to year with an average of 28% in the study period. The increasing issues over water scarcity despite the improvement in the coverage of domestic water demand suggest further investigations. Yet, despite the large gap between supply and demand in the tourism sector the industry still can have undisrupted clean water throughout the year. This indicates the use of alternative clean water which can be obtained locally such as groundwater. Wise water management through the sharing of scientific data, including in the tourism sector is imperative in solving water scarcity in Bali.  Keywords: clean water demand, water scarcity, Badung Regency

Water is essential for life, but not all people can access tap water. In fact, many people use ground water, which is not measured its purity, to supply household, places of worship, public facilities, private offices, government offices, and etc. This problem was also observed on Al-Ikhwan Mosque building Jl. Masjid RT 01 RW 08 Rancagong Village, Legok District, Tangerang Regency, Banten Province. In addition, in this place the water installation was not available. Therefore, it was feasible to carry out community service activities in that location regarding to clean water supply and installation. The method of this project were (1) drilling to make wells as clean water supply, (2) Calculating the need for clean water as the basis in determining the capacity and the type of water pump, (3) building water storage (equipped with a floating sensor as a control media turn the pump on or off automatically), and (4) piping to support distribution system of clean water from well to tap. This method was expected to meet Indonesian National Standard of clean water installation system. This project was supported by lecturers / instructors as their responsibility to practice Tridharma of higher education. Cadets/students was also involved in this project so they can demonstrate their knowledge about standard of building facilities in society.

ABSTRACTThe clean water supply system network on Lengkang Kecil Island was developed in 2019. A small portion of the community's freshwater comes from harvesting rainwater and dug wells, which are only obtained during the rainy season. The primary source of clean water used by the community comes from underwater pipelines with a daily discharge of 0.86 l/sec. The water supply of the Lengkang Kecil Island community is 74.3 m3/day, with 146 House Connections (HCs) and to serve public facilities such as elementary schools, primary health centers, and mosques. Hydraulic evaluation of clean water distribution using EPANET 2.0 software on flow velocity shows the lowest rate of 0.29 m/s and the highest of 1.21 m/s. The lowest pressure value in the distribution system is 6.94-6.96 m and headloss units in the range 0.08-0.25 m/km. These three criteria are still within the distribution network design criteria (feasible). A carbon footprint can be calculated from each activity from the analysis of the evaluation of clean water distribution networks. The most massive emissions came from pumping activities with 131 kg CO2-eq, followed by emissions from wastewater 62.5 kgCO2-eq. Further research is needed to determine the quality of wastewater and the design for a centralized wastewater treatment plant (IPALT) to improve Lengkang Kecil Island residents' living standards.Keywords: Lengkang Kecil Island, water, EPANET, carbon footprintABSTRAKJaringan sistem penyediaan air bersih pada Pulau Lengkang Kecil dimulai pada tahun 2019. Sebagian kecil air bersih yang digunakan masyarakat berasal dari pemanenan air hujan dan sumur gali yang hanya didapat pada musim hujan. Sumber air bersih utama yang digunakan masyarakat berasal dari pengaliran perpipaan bawah laut dengan debit harian 0,86 l/detik. Kebutuhan air masyarakat Pulau Lengkang Kecil adalah 74,3 m3/hari dengan 146 Sambungan Rumah (SR) serta untuk melayani fasilitas umum seperti sekolah dasar (SD), puskesmas, dan masjid. Evaluasi hidrolis distribusi air bersih dengan menggunakan software EPANET 2.0 terhadap kriteria kecepatan aliran menunjukkan nilai terendah 0,29 m/s dan tertinggi 1,21 m/s. Nilai sisa tekan dalam sistem distribusi adalah 6,94–6,96 m dan unit headloss pada kisaran 0,08–0,25 m/km. Ketiga kriteria ini masih berada dalam kriteria desain jaringan distribusi (layak). Dari analisis evaluasi jaringan distribusi air bersih, dapat dihitung jejak karbon yang dihasilkan dari setiap kegiatannya. Emisi terbesar berasal dari kegiatan pemompaan dengan nilai 131 kgCO2-eq, diikuti dengan emisi yang berasal dari air limbah dengan nilai 62,5 kgCO2-eq. Penelitian lanjutan diperlukan untuk mengetahui kualitas dari air limbah dan desain untuk instalasi pengolahan air limbah terpusat (IPALT) untuk meningkatkan taraf hidup penduduk Pulau Lengkang Kecil.Kata kunci: Pulau Lengkang Kecil, air, EPANET, jejak karbon
