Abstract

The extent of critical and potential critical land in the Kambaniru watershed has encouraged community perceptions where management of land and forests in the watershed-based area of community empowerment is an important effort. To be able to achieve a good Kambaniru watershed condition, the behavior and activities of land and forest utilization by the community must comply with the principles of soil and water conservation. High population growth rate and followed by pressure on land has the potential to create new social problems in the form of poverty. On the other hand, the large potential of people who are willing to provide hydrological environmental services in watershed areas can be used as government investment. Therefore, opportunities for community participation need to be managed through an incentive approach through a cost-sharing mechanism. The overall objective of this study is to formulate a cost-sharing regression model of hydrological environmental services; to analyze the value of hydrological benefits for households at the upstream level in the Kambaniru watershed area, and assess the condition of community poverty levels based on pressure on land in the Kambaniru watershed area. This study concludes the formulation of the cost-sharing regression model of hydrological environmental services in the Kambaniru watershed area can explain the condition of the amount of water use and water requirements for households. The condition of population poverty is triggered by high pressure and dependence on land and forests. The recommendation is that farmer household should be given hydrological benefit compensation and lending without interest.

Abstract

Water for an industry is a supporting material for both direct and indirect activities to support several systems. Requirements for the quality of water used in industry vary depending on its intended use. Water that comes from nature generally does not meet the necessary requirements so it must undergo a processing process first. Raw water sources play a very important role in the clean water industry. Raw water is the beginning of a process in the supply and treatment of clean water. Water Treatment Plant (WTP) or Water Treatment Plant (IPA) is a system/facility that functions to treat water from contaminated raw (influent) water to obtain the desired water quality treatment according to quality standards. The purpose of this study was to determine the effect of treated water quality and backwash effectiveness by comparing the values of chemical and physical parameters before and after the backwash process in the filtration process unit of a clean water treatment plant. After conducting the tests, it was concluded that the backwash process is very effective in maximizing the performance of a filtration process unit. The effective value of acidity (pH) is (0-5)%, hardness and turbidity is (40-50)%, total dissolved solid (TDS) is (5-10)% and conductivity is (10-20)%. This also shows that the quality of the water tested has met the quality standards in accordance with Permenkes No. 492 of 2010.
