Analysis of Clean Water Needs Rural Community Based ( A Case Study Hippam Campurrejo Makmur Bojonegoro )

The problem of providing clean water is currently a special concern for both developed and developing countries. Indonesia as a developing country cannot be separated from the problem of providing clean water for its people. One of the main problems faced is the unavailability of clean water sources, the unequal distribution of clean water services, especially in rural areas and the existing clean water sources have not been utilized optimally.villageCampurrejo subdistrict BojonegoroBojonegoro Regency is in dire need of adequate clean water, because so far residents have had difficulty getting clean water, especially during the dry season, some residents only rely on water in old springs/wells without adequate facilities. The research objectives are, 1) to know the speed ofthe need for clean water in the village of Campurrejo sub-district Bojonegoro, Bojonegoro Regency tohi year 2031, 2) What is the reservoir capacity needed to meet the need for clean water in 2031? Analysis of the calculation of population growth in the village Campurrejo subdistrict Bojonegoro the author uses the Geometric method. And it can be seen that the population in the village Campurrejo subdistrict Bojonegoro reached 6,829 people, and the water demand in 2031 according to the prediction of the population is 1,105 liters/second, the maximum daily needs is 1,326 liters/second, and the discharge at peak hours is 1,768 liters/second.And the demand for clean water in Campurrejo Village in 2031 according to the prediction of the number of HIPPAM customers is 1,623 liters/second, the maximum daily need is 1,948 liters/second, and water needs at peak hours are 2,567 liters/second. Prediction of the number of customers of HIPPAM "Campurrejo Makmur" in 2031 is 1298 SR The need for reservoir capacity to meet the needs of clean water in 2031 is 157 m3. Since the reservoir capacity is only 18 m3, it is necessary to add another 139 m3 to meet the needs of HIPPAM customers "Campurrejo Makmur"


Introduction
Clean water is a source of natural ecosystems for human survival that is needed in a sustainable manner. Everyone's condition of the availability of clean water is a daily necessity in community activities in sufficient and suitable quantities. The need for clean water in the household, industrial, plantation sectors and other facilities. It will continue to grow along with the increasing number of population and in terms of the development sector in various fields. Then the problem arises that the number of clean water providers is small, so that water needs are not fulfilled.
This clean water supply system is planned so that residents can meet their water needs without having to bother taking them directly to water sources that are very difficult to reach. By paying attention to the location and the existing potential, it is hoped that the need for clean water in Campurrejo Village, Bojonegoro District, Bojonegoro Regency can be fulfilled as a whole.
The level of economic growth and the increasing number of residents, the available facilities need to be optimized both in terms of services and the provision of clean water facilities themselves. Therefore, a clean water distribution pipe network plan was made in Campurrejo Village which seeks to provide an effective and efficient clean water drainage system in order to improve services to the community, from the wellbore water source HIPPAM Campurrejo Makmur Bojonegoro,The clean water supply system must be able to provide sufficient air for the required needs. Requirements The drinking water supply system must consist of technical provisions: Raw water unit, production unit, distribution unit, and service unit.
To find out the estimated amount of clean water needs to be planned from population growth in the coming years, several methods are used, including arithmetic methods, geometric methods.

a. Arithmetic Method
This method is used when periodic data shows the number of additions that are relatively the same every year. This happens in cities with a relatively small area.

d. Non-Domestic Water Supply Standard
Non-domestic water supply standards are determined by the number of non-domestic consumers which include facilities such as offices, health, industrial, commercial, public, and others. To predict the development of non-domestic water needs, it is necessary to know the city development plan and its activities. If it is not known, then the prediction can be based on a population equivalent, where nondomestic consumers can be counted following the development of domestic water supply standards. Thus we need to know the type and number of future means or in other words we need to know: 1) Types and number of facilities currently available, this data is needed as a basis for calculating the estimated type and number of facilities in the future; 2) Estimated development of the type and number of facilities in the future. https://ejournal.worldconference.id/index.php/eko eISSN: 2685-3264 Attribution 4.0 International (CC BY 4.0) You are free to: Sharecopy and redistribute the material in any medium or format, Adaptremix, transform, and build upon the material for any purpose, even commercial

Data Source
Data sources are anything that can provide information about data. Based on the source, the data is divided into two, namely primary data and secondary data : Primary data collection methods are as follows:

Observation Method
The location of a clean water source that is not far from the author's residence makes observations on the location and shape of the existing reservoir building optimal because it can be done repeatedly in order to get authentic and specific data.

Interview Method
The author also uses the interview method, namely by interviewing HIPPAM technical employees, in Campurrejo Village, Kec. Bojonegoro Kab. Bojonegoro.
Secondary data was obtained through various sources, namely literature, articles, and sites on the internet related to the research carried out. And archival data obtained from relevant agencies, as well as data -data that affect the research, among others: 1. Topographical Data The topographic data used by the author here comes from a Google Earth map which contains regional contour data in Campurrejo Village district. Bojonegoro, Bojonegoro Regency.
