Population growth and urban development continue to increase at an unprecedented rate and create pressure on the quality of clean water. Previous empirical studies have shown that uncontrolled population growth has a negative and significant impact on the quality of clean water. In the case of Indonesia, the population growth trend has decreased every year, but not followed by an index of water quality that should have increased. This study examines population growth in the water quality index in 33 provinces in Indonesia during 2013-2017 using the panel method of fixed-effect models. This study found that population growth has a negative and significant effect on the water quality index in Indonesia. Every 1000 population in-crease will reduce the water quality index by 0.04 (ceteris paribus), which indicates that there is a need for control of the population growth rate to be more aware of the preservation of a sustainable environment.

Abstract Cimahi City is currently experiencing a clean water crisis, the cause of which is increasing population growth, so that water needs increase and land conversion, which results in reduced groundwater infiltration. The primary source of clean water in this city is groundwater. Population growth and residential development have an impact on pollution originating from domestic waste. These two things cause the quality and quantity of groundwater in Cimahi City to be increasingly critical. This study aims to analyze the quality of groundwater used by residents of Cimahi City. The data used is secondary data from the Environmental Service in 2019. Sampling was carried out at thirty points in Cimahi City spread over 14 urban villages, namely Citereup, Pasir Kaliki, Cibereum, Cibabat, Cipageran, Cimahi, Leuwigajah, Setiamanah, Karang Mekar, Cibeber, Melong, Cigugur, Padasuka, and Utama. The number of sampling is 1-2 samples/urban village. Based on the results of the analysis of parameters that do not exceed the required quality standards based on the Regulation of the Minister of Health of the Republic of Indonesia No. 32 of 2017 concerning the requirements and supervision of pristine water quality, namely: turbidity, Manganese, nitrate, detergent as MBAS, and total coliform. Based on the results of calculations with the water quality index, it is stated that the quality of groundwater in Cimahi City is in the normal-poor category.

Megatrends of population growth, urbanization and global warming are making it more and more difficult to find clean water for our needs. Global demand for fresh water grows at 2-3%/year while availability of fresh water has not been increasing. Regional differences in the growth rates are big. The main sustainability objective in water processes is balancing the demand – supply equation. Human impact on the atmosphere seems to aggravate the water availability problem. Over two thirds of global fresh water need is for agriculture. Current practices and technologies in managing water streams are not enough in the future.

The Future

Just a few decades ago, Adyar River in India’s city of Chennai was an important source of water for various uses. Due to local and global changes (e.g., population growth and climate change), its ecosystem and overall water quality, including its aesthetic value, has deteriorated, and the water has become unsuitable for commercial uses. Adverse impacts of excessive population and changing climate are expected to continue in the future. Thus, this study focused on predicting the future water quality of the Adyar river under “business as usual” (BAU) and “suitable with measures” scenarios. The water evaluation and planning (WEAP) simulation tool was used for this study. Water quality simulation along a 19 km stretch of the Adyar River, from downstream of the Chembarambakkam to Adyar (Bay of Bengal) was carried out. In this analysis, clear indication of further deterioration of Adyar water quality by 2030 under the BAU scenario was evidenced. This would be rendering the river unsuitable for many aquatic species. Due to both climate change (i.e., increased temperature and precipitation) and population growth, the WEAP model results indicated that by 2030, biochemical oxygen demand (BOD) and Escherichia coli concentrations will increase by 26.7% and 8.3%, respectively. On the other hand, under the scenario with measures being taken, which assumes that “all wastewater generated locally will be collected and treated in WWTP with a capacity of 886 million liter per day (MLD),” the river water quality is expected to significantly improve by 2030. Specifically, the model results showed largely reduced concentrations of BOD and E. coli, respectively, to the tune of 74.2% and 98.4% compared to the BAU scenario. However, even under the scenario with measures being taken, water quality remains a concern, especially in the downstream area, when compared with class B (fishable surface water quality desirable by the national government). These results indicate that the current management policies and near future water resources management plan (i.e., the scenario including mitigating measures) are not adequate to check pollution levels to within the desirable limits. Thus, there is a need for transdisciplinary research into how the water quality can be further improved (e.g., through ecosystem restoration or river rehabilitation).

Need for clean water is a very important issue and still can not be resolved, especially in the peatlands. Clean water is used for everyday purposes must comply with the requirements of water quality in accordance with the Minister of Health Decree No. 416 / Menkes / per / 1990 on the conditions and water quality control. Peat water which is a source of raw water is very abundant, whereas in the processing of peat water into clean water using a coagulant has been no literature to say exactly how many doses of coagulant used, so this research is very important to do. Therefore, this study aimed to determine the effectiveness of the use of alum, clay and a combination of both on peat water treatment. This research method using a completely randomized design-RAL (Completely Randomized Design) with two factors, alum and clay and performed repeat three times with water media processing tool is simple. Test parameters are pH, color, 6 valence chromium (Cr), manganese (Mn), iron (Fe), sulfate (SO), chloride (Cl), organic substances as KMnO4 (ZO), and hardness (CaCO3). Analysis of the data used in this study is the determination of the effectiveness of the coagulant, ANOVA test (F test) and Duncan Multiple (Duncan's Multiple Range Test). The results showed that the most effective coagulant addition is the clay of 2 g / l in combination with alum to 200 mg / l, where the combination of this coagulant obtain a pH level of 6.53 mg / l, 113.67 PtCo color, 6 valence chromium (Cr) 0,017 mg / l, manganese (Mn) 1.07 mg / l, iron (Fe) 0.39 mg / l, sulfate (SO) 108.31 mg / l, chloride (Cl) 36.56 mg / l, substance organic as KMnO4 (ZO) 90.01 mg / l, and hardness (CaCO3) 53.38 mg / l. Effectiveness and clay alum as a coagulant for peat water treatment discussed in more detail in this paper.

Decision Making Tool

Population projections serve as a decision-making tool or as a tool to help contribute to discussions on the future of our societies. These projections are based on a series of choices made by the modeller about the projection methodology and the future trends in the population growth components (fertility, mortality and migration). To use these projections wisely, users should be aware of the impact of these choices on the results of a population projection. This article highlights the crucial role of the assumptions made on the future trends of the population growth components on the projection results, using population projections for Belgium published by national and international institutions.
