Abstract

One of the chemical parameters in the requirements of clean water is water hardness. Hardness is a term used in water containing cations that cause hardness. Generally, hardness caused by the presence of metals or cations which have a valence of 2, such as Fe, Sr, Mn, Ca and Mg. The purpose of this research is to determine the effect of banana stem charcoal as an adsorbent in reducing water hardness. The process of charcoal banana stem adsorbent dried under the sun for one week, and in the oven at 110°C for 24 hours to reduce moisture and moisture content. Next, to remove volatile materials, the hydrolyzed sample was heated at 400°C to become charcoal with 30 minutes in the furnace after which it was sieved with 106 µm and 250 µm sieves and stored in a desiccator. From the results of the study, it found that the banana charcoal adsorption process can reduce the water hardness level to reach 43.56% for the contact time of about 240 minutes with the thickness of the charcoal used around 5 cm. Then from the t-test analysis showed a significant difference before and after using banana stem charcoal as an adsorbent medium. Banana stem charcoal can be an alternative to adsorbent media to reduce the level of water pollution in addition to other media that commonly used.

Abstract

Determination of water quality status based on the pollution index method. Water said to polluted if it cannot use according to its standard designation. The purpose of this research is to identify and find out the level of pollution contained in shallow well water used by communities in urban areas. Water quality index measurements using the Storet Method. This study uses ten samples with techniques Purposive random sampling with well water sources used by people in Makassar, especially in Untia Sub-District, Makassar, South Sulawesi. The number of samples used was 15 water samples taken each week with a total of 10 shallow well water sample points. The parameters measured in the study are Iron (Fe), Manganese (Mn), Total Coliforms, Total Dissolved Solids (TDS). The results of the study showed that the condition of shallow well water quality classified in category D, which heavily polluted which means it not recommended to use before filtering. The increase in parameters that have exceeded the maximum quality standard comes from natural sources and high domestic waste from community activities. Water pollution is a condition in which a water reservoir changes due to human activity — the change caused by the entry of substances that should not be in the water.

Abstract

Brackish water is one source of clean water and drinking water in coastal areas, river estuaries, and small islands. Various studies have carried out that the use of clay can reduce minerals in the water. This research aims to find out and analyze the Cascade Aerator System and Rapid Sand Filter based on Clay in Reducing Iron Concentration in Well Water. The type of research used is experimental with a quantitative approach. In this study, the researchers used the Pretest-Posttest Control Group Design. The study's location was conducted on Sapuli Island in Pangkep Regency, South Sulawesi Province, and Sindulang Satu Village in Manado City, Central Sulawesi Province. The study's design used a Completely Randomized Design (CRD) with a combination of treatments that obtained 6 x 3 = 18 treatment combinations. This study's population is all well water that is in two research areas, and then the sample collection technique is used simple random sampling with 15 samples of well water. The research obtained a decrease in the maximum average iron (Fe) level obtained reached 57.27% by adding a 20-gram of clay as desalination in 10 liters of well water. The decline that occurred in the two study sites did not differ significantly. Reduction of Iron (Fe) levels through Cascade aerators and Rapid Sand Filters by adding clay as a binder due to the material of kaolin in clay.
