Abstract

Waste from abattoir activities has high organic matter content. One wastewater alternative that suitable for abattoirs is used to utilize a combination of the anaerobic biofilter and aerobic biofilter. Which including a coarse screen, sedimentation, anaerobic biofilter, and aerobic biofilter. It made the treatment system can reduce levels of BOD snd COD waste batters. This study aims to determine the difference between the residence time variations of aerobic biofilter in reducing the BOD and COD levels of wastewater from abattoirs. The research is experimental. Using one group pretest-posttest design. Data analysis used the analysis of variance = 0,05.The analysis result of BOD and COD content wast decreased after treatment at each residence time, with 6 hours of residence time in an aerobics biofilter was reduced 70 percent BOD levels and 66,2 percent COD. 24 hours residence time had the ability to reduced 80 percent BOD content and 7 percent of COD content.Based on a one way analysis of variance results that there is a significant difference from all residence time because of Pvelue (0,00

Abstract: The Pattern Of Chemical Pollution In Riam Kanan River, Kabupaten Banjar. Riam Kanan river is utilized by the community for various needs, such as for households, cultivation of fish in keramba, mining of sand and coral. This research aimed to know the pattern of chemical pollution in Riam Kanan river, which was related to flow direction, pollutant source especially keramba of fish, and flow rate, with the parameters of pH, dissolved oxygen (DO) and biochemical oxygen demand (BOD). The research was conducted by observation, field measurement and laboratory examination. Water sampling was done at 8 location : The reservoir of Riam Kanan, PLTA Ir. P. M. Noor, Tambela Sari Village, Tambela Village, Awang Bangkal Village, Mandikapau Village, The Dam of Irigation Karang Intan, and Sungai Asam village with length of rivers 13.41 km. The results showed that the flow of river ranged from 15.53 to 147.72 m3/sec,. The pH of water ranged 6.13 - 6.70. DO levels ranged 2.34 - 6.95 mg/L while BOD levels ranged 1.16 - 2.91 mg/L. The utilization of river flow for keramba of fish, households activities and sand and coral excavations had affected the quality of water, especially the level of dissolved oxygen along the river flow.

Abstract: Water Quality Improvement Using Aloe Vera Gel. Some people on the Trikora road, Sidomulyo Permai Ujung Complex, Banjarbaru City use swamp water with turbidity levels that do not meet the requirements, namely 42 NTU. Water sources that do not meet the requirements must be processed. Aloe vera as a natural coagulant contains mucilage which contains polygalluronic acid as a coagulant with the mechanism of adsorption and incorporation. This study aims to determine the effectiveness of dose and time variation of aloe vera gel contact as a natural coagulant in reducing turbidity of swamp water. This type of research is experimental, namely to determine the optimum dose and contact time of aloe gel as a natural coagulant. The design of this study uses Postest Only Design. Data analysis usingstatistical test Two Way Analysis of Variance with α = 0.05. Turbidity level analysis results decreased after treatment of variations in dose and contact time, the optimum dose of 1.2 grams in the contact time of 20 minutes was able to reduce turbidity of 41,63% with turbidity value of 10.73 NTU, pH 4.6 and temperature of 28.5oC. It can be suggested for further research there should be an addition of natural additives that are alkaline to increase the pH of the water.

Abstract

The amount of Fe in groundwater is usually quite high and causes the water to turn yellow-brown in color. According to preliminary test results, Fe levels were 4.62 mg/L and pH was 4.3 in one of the drilled wells in Banjarbaru, which did not fulfill quality criteria. Using zeolit and cassava peel to enhance Fe levels can be taken as an option. The aim of this study was to determine the effectiveness of the combination of zeolite and cassava peel in improving Fe and pH levels in a drilled water well. An experiment with a post-test only control group design was used for this study. The research population was the entire water supply from one of Banjarbaru’s drilled wells. The research sample was drilled well water, which was taken in part for testing. The Kruskal-Wallis test was employed to analyze differences in Fe levels, followed by the Mann Whitney test with a p-value < 0.05, indicating that there is a significant difference in Fe levels after treatment with combinations A, B, and C. According to the study’s findings, combinations C were the most effective in increasing the Fe levels and pH of drilled well water by up to 0.91 mg/L (78.32%) and 7.2.
