The high nutrient content in the leather tanning industry sludge is the basis for exploiting the sludge as a mixture of growing media for red shoots. The aim of this study was to determine the ability of red shoot plants to provide sludge for IPAL for the leather tanning industry and to determine the concentration that could be used as a mixture of growing media for red shoots. Variations in the composition of sludge:soil, namely 5%: 95%, 10%: 90%, 15%: 85%, 20%: 80%, 0%: 100%. This research lasted for 3 weeks with observations every 3 days of the height and diameter of the stem. The results showed that Syzygium oleana could survive from the beginning to the end of the study by giving the appropriate sludge concentration because the nutrient content was high so that it affected plant fertility both in height growth and increased plant diameter development compared to control plants. The concentration of sludge that can be used as a mixture of growing media for red shoots is below 50%. Keywords: Leather Tanning Industry, Sludge IPAL, Syzygium oleana

Water from cattle farming operations that is not properly managed and discharged directly into the environment can cause unpleasant odors and increase the risk of contamination of surrounding water bodies. The purpose of this study was to determine an effective management system in solving odor problems and the risk of contamination of water bodies. The method in this research includes the design of a management system and laboratory-scale processing experiments involving the oxidation pond as the processing unit. The cattle farm liquid waste management system consists of 3 stages, namely pre-treatment, primary treatment, and secondary treatment, where there is a processing unit (oxidation pond) for secondary treatment. Wastewater is treated in the oxidation pond with a variation of the injected oxygen discharge of 6 L / minute, 8 L / minute, and 11 L / minute with residence time during the calculation time according to EPA / 600 / R-11/008 of 2011 (respectively 0.256 days, 0.1356 days, 0.1096 days), 3 days, 7 days, and 14 days were equipped with control of oxidation-reduction potential (ORP) values. The parameters observed were odor, Biochemical Oxygen Demand (BOD) and Total Ammonia (NH3-N). Where the wastewater after the treatment process is yellowish with low turbidity and has no smell. While the test results after the study showed that the average BOD level had met the quality standard. With the highest final BOD level was 152 mg / L and the lowest was 98 mg / L. Meanwhile, the highest total ammonia levels after research were 0.0088 mg / L and the lowest was 0.00032 mg / L. Management with an oxidation pond as a processing unit is effective in overcoming odor problems and reducing levels of BOD and ammonia pollutants.

VARIASI TRAY AERATOR DENGAN PENAMBAHAN MEDIA KAOLIN DAN KARBON AKTIF UNTUK MENURUNKAN (Fe) DAN (Mn) TERLARUT DI AIR SUMUR Hamsah Karuniawan; Munawar Ali

Ground Water as an alternative to clean water is often found to contain iron (Fe) and (Mn). The content of Fe and Mn causes a yellow-brown color and leaves a yellow stain on the fabric. Fe content can cause health problems such as nausea when consumed, intestinal wall damage and irritation to the eyes and skin. Meanwhile, Mn content above the quality standard can cause disturbances in the vascular vessels, heart and nervous system. This well water can be treated in several ways, one of which is aeration. Aeration is the process of adding air to water through contact between water and air. There are several types of aerators, one of which is the Tray aerator. The Tray aerator is aerated with a vertical Tray arrangement. The water will pass through the perforated Tray level and will be caught at the bottom. To increase the efficiency of reducing Fe and Mn levels, it can be done by adding Kaolin media and activated carbon. The effect of aeration time is directly proportional to the decrease in Fe and Mn levels. The longer the aeration time, the more significant the decrease in Fe and Mn levels. the contact time between water and gas becomes longer. As a result, the transfer of oxygen from the gas phase to the liquid phase can be maximized. The results of this study indicate that the addition of adsorbent media in Tray aerator variations affects the percent removal of Fe and Mn levels in well water. With the highest percentage removal of Fe was 86.09% with a result of 0.64 mg / l using 500 gr kaolin media for 90 minutes and the highest percentage of Mn removal was 88.70% with a yield of 0.26 mg / l in 90 minute

PERSEBARAN AIR LINDI TPA BENOWO TERHADAP KUALITAS AIR TAMBAK Munawar Ali; Annisa Nurjanna

The Benowo Landfill (TPA) in Surabaya applies the Open Dumping method so that it has the potential to produce leachate which can pollute the surrounding environment. The leachate storage system in TPA Benowo also plays a role in the possibility of leachate leaking into groundwater and polluting the quality of freshwater aquaculture pond water around Benowo TPA. The method used is the purposive sampling method, which is by taking several samples scattered around the center of the Benowo landfill waste dump, then testing the COD concentration, which is then the results of the COD measurement, plotted on a map to analyze the distribution pattern. The results showed that there was an indication that pond water around the Benowo landfill had been contaminated with leachate which was shown by the COD concentration in 14 test samples, only 3 according to the quality standard of PP RI No.82 of 2001.

The demand for cement in Indonesia in the last 10 years has increased by 63%. One of the raw materials for making cement is obtained from mining activities, namely limestone and clay. The method used in this research is Life Cycle Assessment. .Life cycle assessment is used to conduct an environmental impact assessment and using a cradle to gate approach. The data for each processing process is analyzed using SimaPro software. The biggest impact contribution from LCA analysis on the mining process is Fine particulate matter formation and global warming (Human Health). The suggested alternative improvement program is air control or pollutant control by reforesting and developing green open spaces around the cement industrial area of Tuban Regency
