Abstract

The kafe business experienced an increase of 16-18% in 2019 so that the waste generated also increased. Kafe waste has the same characteristics as domestic liquid waste with some characteristics being BOD, COD and fats. The exudate produced by plant roots is beneficial for microbes in helping to decompose organic matter. Thus, the purpose of this study was to determine the effect of cutting the roots of aquatic plants on the removal of BOD and COD levels in domestic waste and their effect on the growth of the number of microorganisms. In this study, two stages were used. The first stage is the pre-treatment stage starting from plant propagation, acclimatization, range finding test (RFT), cutting roots (with variations of 0%, 25% and 50%) and using Grease trap to remove oil and fat content. Then the core research stage is the removal of BOD and COD using the phytoremediation method with water hyacinth. From this research, it was found that the variation of plant stems and 50% root prunning on the 25th day had the most effective BOD and COD removal capabilities, namely 95.60% for BOD removal and 93.37% for COD removal. In addition, the results of this study also prove that there is an influence between the treatment of cutting plant roots and the growth of the number of microbes. This is evidenced by the large number of microbes in the 50% root cutting treatment, which is 101.24 mg/L

Abstract

Water is an important resource for human survival. In Palembang, raw water is sourced from the Musi river. Meanwhile, more than 80% of the waste generated by human activities is discharged into rivers. Building houses on the banks of the river has become a culture in the city of Palembang. This culture causes sanitation problems on the riverbanks. This study aims to identify the feasibility of Musi River water as a source of clean water. Measurements were made at 8 points, namely the Karang Jaya area, Keramasan, Karang Anyar, 14 Ulu, Tangga Buntung, Sekanak market, Kuto Market, and the Bagus Kuning area. The measurement results are obtained: pH = 6.575±0.05 (6.5-6.6); BOD = 1.291±0.449 (0.6-2.12); COD = 17.5±20.177 (5.0-65.0); NH4 = 0.174±0.310 (0.02-0.94); TSS = 57.125±14.61 (42.00-84.00); Fe = 0.936±0.271 (0.46-1.30). Based on these results, it can be concluded that the pH is still on the threshold at all points; BOD is still on the threshold at all points; COD above the threshold only in the stump area; NH4 above the threshold only in the Jaya Coral area; TSS above the threshold in the Jaya Coral area, Keramasan, New Coral, Sekanak market, and yellow good area; Fe > 1 in the stump area, Sekanak market, and Kuto market area. In general, based on the results of the identification of the Musi river water, it is still suitable for use, but must be treated first.

Abstract

Heavy rains occurred in the Lasalimu District, Buton Regency, Southeast Sulawesi on June 18, 2022. Based on information from the Regional Disaster Management Agency (BPBD) of Buton Regency, this incident resulted in a catastrophic flood that submerged 129 houses in the area. This study aims to analyze the dynamics of the atmosphere and rainfall at the time of the flood in Buton Regency on 18 June 2022 based on Himawari-8 satellite data. The Himawari-8 satellite data processing in this study uses the SATAID application to determine the condition of atmospheric stability and the process of convective cloud growth. Statistical analysis was also carried out by processing rain post data around the Kab. Buton. The results of time series analysis and cloud top temperature contours indicate the presence of Cumulonimbus convective clouds with a very low peak temperature of -81.4°C. Analysis of the average atmospheric stability index shows the presence of atmospheric instability conditions. The results of daily rainfall data analysis also show that there has been very heavy rainfall in Buton Regency. From the analysis of the streamlined wind layer of 850mb, it is known that there are turns and wind decelerations, and based on the sea surface temperature anomaly, the conditions are warm around the Buton Regency area.

Abstract

Leachate waste is water seepage from buried garbage. Leachate water contains organic compounds in the form of hydrocarbons, sulfuric acid, tannic acid, humic acid, gallic acid and contains inorganic compounds in the form of sodium, potassium, magnesium, chlorine, and other heavy metal compounds that have high concentrations, so that they have the characteristics of COD (608.6 mg). /liter), TSS (5280 mg/liter), and TDS (1925 ppm) are high and dangerous for aquatic ecosystems if discharged directly into water bodies. This study aims to determine the efficiency of leachate treatment using a coagulation flocculation reactor and a photofenton reactor. This study used the Jartest method with different concentrations of Fenton's reagent. In the coagulation flocculation pretreatment using AlSO4 coagulant as much as 16 grams/liter which is able to remove COD by 52%, TSS by 70%, TDS by 50%. Furthermore, the water resulting from the coagulation of flocculation is treated by the photofenton method. In the batch system the efficiency of reducing COD, TSS, TDS obtained at the ratio of FeSO4: H2O2 (1:10) within 30 minutes was 30%, 93%, 2%. Then the best results were obtained from the batch system, followed by a continuous system which obtained the final results of the removal of COD, TSS, TDS reductions which were obtained respectively 80%, 45%, 48%. The final results of processing the COD, TSS, TDS parameters using the photofenton method were 29.09 mg/liter, 440 mg/liter, and 336 ppm respectively.

Abstract

The restaurant business is growing rapidly in big cities these days, increasing demand for people looking for fast and convenient dining service. Wastewater produced by untreated restaurants can cause increased levels of COD, BOD, TSS, and fatty oils in water bodies. In restaurant wastewater treatment that only uses a grease trap, it required. One of the treatments that can be applied to improve the quality of wastewater from restaurant waste processed by grease trap is by using the aerobic biofilter biological treatment process. Aerobic biofilter is a biological treatment that utilizes media as a place for microorganisms to breed and helps to degrade the pollutant load in restaurant waste in the presence of oxygen supply in the treatment. This research uses an aerobic biofilter with variations in the porosity of the media volume and the best residence time to proceed a continuous system. From this study, the optimal results obtained in thebatch system were COD 88,8%, TDS 79,5%, TSS 85,3% with a residence time of 15 days at a volume porosity of 75% bioball media. The percentage of removal in the continuous system works is stable, namely the removal efficiency of COD  88,6%, TDS 77,6%, and TSS 83,6%.

Abstract

The problem of waste, especially household (organic) waste that has not been processed properly is certainly a big problem. The reason is because the waste management system and handling are not well organized. One solution in handling household waste (organic) can be done through composting using biopori infiltration holes and composter media. This study aims to determine the percentage of waste reduction, as well as to determine the comparison of compost yields from the two composting media. The study used 2 reactors in both composting media, with different initial waste weights. The composter uses variations in the initial weight of 3 kg and 4 kg of waste, while in the biopori using variations in the initial weight of waste 2 kg and 1 kg. The results of the percentage of waste reduction obtained from each reactor in the biopore are 50%, 25%, while in the composter are 63%, 50%. In the results of the percentage of waste reduction the best is found in the composting media with a composter. The compost quality parameters tested included pH, moisture content, C-organic, N-total, C/N ratio. The results show that the compost quality in the two composting media is closest to SNI 19-7030-2004 is composting media using a composter.

Abstract

Exposure to cigarette smoke in passive smokers has a bad impact because the substances inhaled are 4-6 times greater than the levels inhaled by active smokers. Nicotine is a dangerous substance in cigarettes that can cause respiratory disease. Rajungan shell waste in Indonesia is very abundant and has a chitin content of 50%-60%. Thus, the purpose of this study was to determine the effectiveness of Rajungan Shell (Portunus pelagicus) as an antitoxic mask coated with Chitosan Polymer Medium (CPM) for nicotine reduction using the spray coating method. Variations in CPM variables were concentrations of 10,000 ppm, 20,000 ppm, 30,000 ppm, 40,000 ppm, and 50,000 ppm with a total of 3 sprays, 5 sprays, and 7 sprays. The results obtained were the degree of deacetylation 69.45%, percent nicotine removal 80.73%, and adsorption capacity of 4,9993 mg/g.
