Abstract

Health care facilities wastewater (HWW), such as hospital, is classified as domestic wastewater according to Minister of Environment and Forestry Regulation No.P68/2016. One of the important parameters is total coliform.  The disinfection process using chlorine is effective in reducing the number of coliforms, but it is indicated to cause residues and side effects for other microorganisms in the receiving water bodies. This research is an experimental study by utilizing ozone and probiotics from whey kefir to eliminate coliform bacteria, aiming to determine the strategy for choosing a method for removing total coliform bacteria in HWW using the Analytic Hierarchy Process (AHP) approach. Data processing used Expert Choice 2011 software and it was found that the criteria with the highest score were environmental aspects, namely 0.302 and the priority indicator being minimizing the risk of pollution with the highest score, 0.366. Determination of strategies in the process of eliminating coliform bacteria in HWW by making choices, between the use of chlorine, ozone and a combination of ozone and whey kefir probiotics with five criterias approach (environmental, technological, social, economic, and institutional). Ultimate priority by using ozon was chosen with a score of 0.449; use of ozone and probiotics is the second priority with a score of 0.316; and utilization of chlorine with a score of 0.235.

Abstract

Rainwater becomes refreshing and safe water for use in daily activities such as bathing and even for consumption through a recycling process. The aim of this study is to analyze the need for clean water, water scarcity and rainwater potential as well as analysis of rainwater utilization with rainwater processing technology. The methods used are the Wet Deposition and Wet & Dry Deposition methods with the Automatic Rain Water Sampler (ARWS). The software used for data processing in this research is Minitab version 21.1. The results of field studies based on data from the Mataram Meteorology, Climatology and Geophysics Agency for the NTB region, in the last 3 years, namely 2017, 2018 and 2019, show that the average rainfall in Mataram is 326 mm/year, which means the potential for rainwater to be reuse is huge. Strategic steps are needed to optimize rainwater potential, investment policies in appropriate infrastructure need to be improved, including rainwater collection systems, storage tanks and water treatment technology. Apart from that, the government's role is important in paying attention to legal, regulatory and environmental sustainability aspects in the development and utilization of rainwater resources so that they can be used as a basic ingredient for clean water needs.
