Fresh water is a vital requirement in human daily life. Teluk Bakung Village relies on fresh water supplies from the Ambawang River and wells made by the community. The condition of well water in Teluk Bakung Village tends to be the color of ground water which is influenced by the roots of trees, blackish brown and high iron content. The purpose of this Community Service activity is to carry out water filtration on gambut soil to improve the condition of fresh water sources at Al-Muhajirin Mosque in Mu'allaf village, Teluk Bakung Village, Sungai Ambawang District, Kubu Raya Regency, Kalimantan Barat as meeting the mosque's needs and the society. The method of applying IPTEKS is by transferring IPTEKS by improving the physical condition of the Al-Muhajirin Mosque building, the application of clean water filtration as well as training the local staffs for operations and maintenance as well as the plumbing network. It is expected that the addition of aeration system groundwater that has iron content will make it clearer than just filtration which has been carried out at that location.

Protein wastes (feathers, goat hair) and cellulosic wastes (corn cob, coconut husks) were collected and washed with detergent solution, thoroughly rinsed and sun dried for 2 days before drying in an oven, and then ground. One-half of ground material was carbonized at a maximum temperature of 500°C after mixing with H2SO4. The carbonized parts were pulverized; both carbonized and uncarbonized sorbents were sieved into two particle sizes of 325 and 625 μm using mechanical sieve. Sorbents of a given particle size were packed into glass column.Then, textile wastewater that had its physicochemical parameters previously determined was eluted into each glass column and a contact time of 60 and 120 mins was allowed before analysis. Results showed 48.15–99.98 percentage reduction of , EC, Cl−, BOD, COD, DO, TSS, and TDS, 34.67–99.93 percentage reduction of , EC, Cl−, BOD, COD, DO, TSS, and TDS, 52.83–97.95 percentage reduction of Pb2+, Ni2+, Cr3+and Mn2+and 34.59–94.87 percentage reduction of Pb2+, Ni2+, Cr3+and Mn2+. Carbonization, small particle, size and longer contact time enhanced the sorption capabilities of the sorbents. These show that protein and cellulosic wastes can be used to detoxify wastewater.

<p>In areas that have not received clean water services, residents usually use well water, river water which sometimes even often the water used does not meet the standards of healthy clean water. To treat well water/ ground water is usually the community. build a processing unit in the form of a sand filter. The problem that is often encountered in treatment is cleaning the filter media. This condition is often difficult for the community to do because it requires time and energy, resulting in the sand filter that is supposed to be operational continuously and finally stops and is not even used at all. To overcome this problem, it can be done by improving the design of water treatment units with a system of combination of aeration and upflow flow filtration. This study is to determine the ability of the tool to improve the quality of shallow groundwater in terms of turbidity, Fe, Mn, color and odor to clean water and saturation point of filtering. Research Design is a "quasi-experiment" in the form of "Time Series Design" using a "pre and post test" design without control. The tool is designed in the form of an application prototype to determine its ability to reduce turbidity, Fe, Mn, color and odor and the length of saturation point. The results showed that iron content before processing 2.12 after processing 2,058. pre-treatment manganese content 0.080 after processing 0.078. Color and smell before color processing and odor after processing are colorless and odorless. Microbiological quality for stool coly before processing week 1 32 after treatment 0, week 2 coly of feces before processing 26 after processing 0 and weeks 3 coly of feces before processing 21 and after processing 0. Length of processing up to saturation point filter media total contact time processing is 30 minutes.</p>

A research was conducted on the soils of teaching and research fadama farm of Kebbi State University of Science and Technology Aliero located at Jega, with the aim of assessing the soil quality irrigated with tube well water of the study area. The entire University Fadama land was divided into three sections namely T1, T2 and T3 and from each section, three (3) composite soil samples were collected. Each soil sample was collected 2meters away from a tubewell where water sample was also collected. Three (3) samples of the tube well water were collected from the three demarcated areas T1, T2 and T3, making a total of nine (9) samples. These samples were collected in a clean 75cl water bottle provided with a cap. Each water sample was analysed for pH, total dissolved solid (TDS), electrical conductivity (EC), sodium adsorption ratio (SAR), magnesium (Mg) and potassium (K). Soil sample was analyzed for pH, organic carbon, total nitrogen, available phosphorus. Result obtained showed that pH was 7.2, TDS 2.55 mg/l, EC 0.25 µs/cm, SAR 1.35, Mg 90.25, K 1.43 and RSC -3.8. Soil analysis showed that organic carbon content was 0.75 g/kg, total nitrogen 0.06 g/kg, Phosphorus 0.65 g/kg and CEC ranged 6.96-7.32 cmol(+)/kg. The study showed that soil in the area were low in fertility, therefore fertilizer of both organic and inorganic should be supplemented to make the soils more fertile. The soils were found to be free from salinity/sodicity problems at least for now.
