“…The amount of dissolved solids contained in groundwater is influenced by the origin of the water source and can be removed through a filtration process using organic, natural or other materials [32]. The water filtration system aims to remove bacteria, impurities and harmful elements as well as purify the water in an effort to obtain standard quality levels of power of Hydrogen and Dissolved Solid water [3,33,34]. Where power of Hydrogen is a chemical parameter that must be in the level of 6.5 to 8.5 mg/l and Total Dissolved Solid as a physical parameter must be above 1.00 mg/l, but below 5.00 mg/l.…”

The results of measuring the power of Hydrogen (pH) of 5.5 mg/l and Total Dissolved Solid (TDS) of 3.20 mg/l level of water wells in a village, including in a school of Madrasah Tsanawiyah Negeri 5 in Tanjung Medan Rokan Hulu is considered not within permissible limit of World Health Organization (WHO) standards. For that reason, experimental research was conducted by firstly designing and making a water filtration device from Polyvinyl Chloride pipe of 4 inch in diameter, 100cm long, and 1 inch channel in and out. With the green method treatment, the biochar used are Coconut Shell Charcoal (CSC) and Bagasse Charcoal (BC), with additives material such as River Sand (RS), Fiber Palm (FP), and Crushed Gravel (CG). The results of the analysis prove that the best performance of Biochar in Water Filtration (BWF) to increase the content the pH of water to 89.09% is done by Coconut Shell Charcoal (CSC) biochar. While the best for reducing the water TDS level is performed by Bagasse Charcoal (BC) at 64.06%. The performance for pH increases and at the same time decreases the TDS level of water is done by Bagasse Charcoal (BC) biochar with a pH of 7.8 mg/l, and a TDS of 1.15 mg/l. Meanwhile, the filtration combination matrix that produces water according to the WHO standard permissible criteria is (A6+B6+C6+D1+E6), (A6+B6+C2+D2+E6), (A6+B6+C3+D3+E6), (A6+B6+C4+D4+E6), and (A6+B6+C5+D5+E6), as well (A6+B6+C1+D6+E6). So, it can be concluded that Biochar in Water Filtration (BWF) needs to be developed.

“…The DS18B20 is a waterproof temperature sensor used to measure liquids, soils, or solutions. The temperature sensor DS18B20 has a temperature measurement range from -55°C to 125°C and uses a 3.0-5.0 V supply for its operation [24] [25]. In reading the aquarium water temperature, we use the DS18B20 sensor, changing the temperature value to voltage.…”
