Abstract

Central Kalimantan has a large area of peatland that contains a lot of peat water, which can be used as a source of clean water and drinking water. Meanwhile, the community still lacks clean water because peat waters are acidic to highly acidic, corrosive, and reddish-black, making them unsuitable for human use.  Therefore, efforts are needed to purify peat water to be suitable for human consumption.  This study aimed to assess the effectiveness of using calcium carbonate lime, alum, and activated carbon to purify peat water.  This research was divided into 2 stages, namely preliminary research by testing the combination of the three materials mentioned above with the dose of each material, 0.3 g/L, 0.6 g, and 0.9 g/L, so that 33 treatments were obtained, namely 27 treatments.  Test parameters in preliminary research are pH, water colour, and water appearance.  In the main research, the observed variables were pH, water colour, TDS, and the appearance of water.  In the main study, the best 6 treatments from the preliminary study were used, where the pH value was close to normal, ranging from 5.76 to 6.16, and the colour value ranged from 4 to 15 Pt-Co, and there was no foam. The best 3 main research results carried out complete testing of physical, chemical and microbiological water quality parameters for clean water, namely physical parameters (colour, odour, taste, turbidity, temperature, and TDS), chemistry (organic matter, pH, hardness, iron, manganese, sulphate, nitrite, chloride, nitrate, zinc, cyanide, fluoride, ammonia, aluminium and copper), and microbiology (total coliform and E. coli). Based on the results obtained, in the main study, the use of a combination of calcium carbonate lime, alum, and activated carbon at doses of 0.3 g/L, 0.3 g, and 0.6 g/L respectively was very effective in purifying peat water into water suitable for human consumption, so these doses are recommended for purifying peat water.

Abstract

Aeromonas hydrophila bacterial attack is one of the factors that affect aquaculture activities and cause losses. One alternative that can be done to treat diseases caused by bacteria is to utilize antibacterials that are environmentally friendly and harmless to the ecosystem, one of which is by utilizing ketapang leaves (Terminalia catappa). Ketapang leaves contain antibacterial compounds such as flavonoids, alkaloids, tannins, triterpenoids/steroids, saponins. This study aims to determine the dose of ketapang leaves to treat diseases caused by Aeromonas hydrophila bacteria in betok fish seeds (Anabas testudineus) with various treatments. The method used in this study was a completely randomized design with four treatments (A, B, C, D) and three replicates (1, 2, 3) namely A (control), B (1000 ppm), C (2000 ppm), and D (3000 ppm) using betok fish as test fish infected with the pathogen Aeromonas hydrophila, then given treatment in the form of soaking using ketapang leaf extract. The results showed that treatment due to disease with Aeromonas hydrophila bacteria in betok fish using ketapang leaf extract was very effective in treatments B, C and D. The best dose was found in treatment D with a dose of 3000 ppm, followed by treatment C with a dose of 2000 ppm and treatment B with a dose of 1000 ppm. The highest growth rate of betok fish fry was found in treatment D at 7.66%, followed by treatment C at 6.33%, and treatment B at 5.33%.
