Masalah penelitian ini adalah kontribusi limbah domestik terhadap kualitas air sungai Tondano-Sawangan Sulawesi Utara.  Penelitian ini bertujuan untuk mengkaji tentang kontribusi limbah domestik penduduk di bantaran sungai Sawangan terhadap kualitas air sungai Tondano-Sawangan Sulawesi Utara. Metode penelitian yang digunakan adalah deskriptif kuantitaf. Teknik pengumpulan data dikumpulkan dari hasil pengambilan sampel di dua lokasi dan perhitungan labolatorium dan dokumentasi yang ada dilapangan. Parameter yang diukur di laboratorium adalah derajat keasaman atau pH, Biochemilcal Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Amoniak, dan Total Coliform.  Hasil penelitian menunjukkan kualitas air Sungai Tondano-Sawangan mengalami penurunan kualitas dari hulu ke hilir yang disebabkan oleh limbah domestik penduduk. Parameter yang dominan memberikan kontribusi nilai indeks pencemar yang tinggi adalah parameter biologi yaitu total coliform. Pencemaran air yang disebabkan oleh kontaminasi limbah toilet merupakan masalah yang cukup serius, dikarenakan adanya potensi penularan penyakit oleh pathogen. Kandungan Total coliform yang terdapat pada air sungai bagian hulu sebesar 24200 MPN/100ml sedangkan bagian hilir sebesar 19900 MPN/100ml, sudah melebihi nilai ambang batas standar baku mutu sesuai Standar Nasional Indonesia. Batas maksimum Cemaran Total Coliform yaitu 3000 MPN/100ml, dengan demikian dapat dikatakan bahwa mutu air sungai Sawangan sudah tidak aman lagi untuk di konsumsi bagi masyarakat, namun untuk kegiatan rekreasi, tambak ikan, dan lain sebagainya masih aman. Parameter lain seperti BOD, COD, pH, TSS, Amonia, masih aman karena berada dibawah standar Baku Mutu.Kata Kunci: Limbah Domestik , Kualitas Air, Pencemaran Air, Baku Mutu

Feasible Alternative

In this study, integrated pretreatments and aerobic digestion processes were investigated in order to provide a feasible alternative that can achieve effective sludge reduction. An ozone treatment in the presence of ionic manganese, a catalyst, increased the sludge reduction ratio three times higher than that of a single ozonation, presumably due to an increase in OH radical production. The ozone treatment yielded the effective sludge reduction ratio with an increasing ozone dosage, and an effective dosage of the catalyst was found to be 4 mg-Mn/g-TS. When a mechanical pretreatment and an ozone/catalyst were applied in a series, the integrated process, even at a half mechanical intensity and a half level of ozone dosage, showed higher and faster sludge reduction than each single process did. In addition, the integrated pretreatment process showed the highest dewaterability of the treated sludges. A ratio of sludge cake generation, which was newly introduced to quantify overall performance of sludge treatment processes, showed that the integrated pretreatment followed by the aerobic digestion yielded approximately a half of the sludge cake volume compared to the single aerobic digestion. Therefore, the integrated pretreatment can be a feasible method for the effective reduction of total suspended solid and the final volume.

Water used for washing carcasses of slaughtered animals and slaughter house is referred to as abattoir wastewater. This study was designed to investigate the microorganisms associated with abattoir wastewater and to establish the biodegradation potential of abattoir wastewater microbiota. Isolation of the microbes was carried out using pour plate technique. The total viable count for the microbes’ ranges from 2.5×104 - 4.6×105 cfu/mL. Results revealed that all the physicochemical parameters exceeded the permissible limits (total dissolved solid (TDS) 1748mg/L, total suspended solid (TSS) 176mg/L, biochemical oxygen demand (BOD5) 91 mg/L and chemical oxygen demand (COD) 227 mg/L). Microorganisms isolated include Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Bacillus anthracis, Aspergillus niger, A. flavus, Mucor sp, Trichophyton quickeanum and Penicillium sp. Some of the microbes were observed to have biodegradation potential by their ability to grow on mineral salt media (MSM) incorporated with starch, cellulose, crude oil, kerosene and diesel as the sole source of carbon and energy. This study suggests that abattoir wastewater harbors microorganisms that could be hazardous to public health when discharged into the environment untreated hence the need for strict monitoring. These microbes isolated could be employed as agent of bioremediation of wastewaters. Key words: Abattoir; Biodegredation; Isolation; Microbiota; Wastewater

Wastewater resulted from the batik dying process is known for its environmentally hazardous substances including hazardous natural and synthetic organic matter, suspended particles, and hazardous metal. But in the micro and medium scale batik textile business, wastewater treatment is mostly not carried because it does not give benefit for the owner. Economical wastewater treatment constructions can be an alternative for the business owner for their free operational cost. Batik wastewater treatment ought to be carried out to meet government standards but most importantly to decrease hazardous pollutant’s concentrations so it does not harm the environment. This society service project aims to provide alternatively economical wastewater treatment for batik business owners by applying simples and cheapest yet effective treatment methods to reduce pollutant concentrations in wastewater. Methods applied in this project including sedimentation, filtration, and landfill-bioremediation. The laboratorium analysis result shows that sedimentation and filtration are significantly reduced total suspended solid particles in wastewater from 2450 to 100 mg/L in line with wastewater decoloring from dark blue to clear yellow.

Phytoplankton plays an important role in primary productivity in marine environment. Various environmental changes in coastal area will impact the water quality and their phytoplankton compositions. The purpose of this study is to examine the abundance of phytoplankton from two different sites, i.e Tanah Merah (close to mining site) and Semujur Island (away from mining site) in Bangka Island. Phytoplankton and water sample were collected on June- August 2018. Water quality was measured using water quality checker, whereas the phytoplankton was identified under the microscope with a magnification of 100x. Non-parametric Kruskal test and T-test analysis was performed to determine the abundance, diversity, uniform, and dominance of phytoplankton between Sites, respectively. Statistical analyses showed the abundance of phytoplankton at Semujur Island was significantly higher than that at Tanah Merah (p = 0.003). In additions the diversity, uniform, and dominance were also significantly different between sites (all p <0.05). In Semujur Island, Diatoms (Thalassiothrix, Chaetoceros and Thalassionema) were more dominants than the Dinophyceae group. However, in Tanah Merah, the genera Ceratium belong to class Dinophyceae was more dominant than the class Bacillariophyceae. These results performed that the phytoplankton in Tanah Merah and Semujur Island was affected by environment, in this case the mining area. The water quality in Semujur Island (non-mining Area) might have good quality than in Tanah Merah (mining area). The average value of turbidity and Total Suspended Solid in Tanah Merah Waters causes low abundance of phytoplankton. It can be concluded that tin mining can disrupt the abundance and composition of phytoplankton as a primary producer of waters.
