Abstract

Air pollution is an annual problem that occur in every city. Surabaya is one of the cities with a fairly dense population so it is directly proportional to the number of motor vehicles used. Motor vehicles and industrial areas were located in Surabaya contribute the largest emissions to the air so they have low air quality because of the pollution. Air quality is closley associated with pollution, to ascertain the levels of contamination are calculated in reference to the Standard Index of Air Pollution. One of the monitoring parameters used is Particulate matter 10. PM10 is a primary pollutant that emits directly into the air which has serious impacts on health and the environment. This research was conducted in Traffic Ring Taman Pelangi Surabaya for 3 days with an interval of weekdays and holidays with time intervals in the morning, afternoon and evening. Analysis of concentration data was calculated using the HVAS tool with the gravimetric method and mapped using the ArcGIS program. The results of the study showed that the highest concentration was at the sampling location point 6 with a value of PM10 = 110.71 μg/m3, and the lowest was at the sampling location point 1 with a value of PM10 = 50.15 μg/m3

Abstract

Kali Jagir is located in Wonokromo District with a total population of 146,785 inhabitants. 24% of land use in the Wonokromo area is a residential area that disposes of domestic waste such as garbage, laundry waste, and other waste into the Surabaya River stream either directly or indirectly. Disposal of domestic waste from residential areas around the Jagir River results in a decrease in water quality, as well as a decrease in the function of the river, and an increase in the pollutant load that will be received by the river. The method used is descriptive quantitative research method. The water sampling point was determined using the purposive sampling method. The data used is primary data from researchers who have conducted quality analysis at three points of Kali Jagir in 2021. Based on the results, the pollution load value of Kali Jagir Surabaya has exceeded the maximum pollution load capacity that can be accepted by water bodies. Total pollution load in Kali Jagir Surabaya based on TSS parameter is 12,360,924.86 kg/day, BOD parameter is 259,169.08 kg/day, and COD parameter is 6,455,103.32 kg/day.

Abstract

This research discusses the processing of tofu wastewater with the aim of reducing and controlling the levels of pH, BOD, COD, TSS and temperature so as not to pollute the environment when dumped into rivers or other suitable places by simple reactors in few days. Water treatment process using bacterial from waste water as medium seems promising to develop since it does need any microorganism stater or other media like glucose. During the process of microorganism growth (seeding), the peak of MLSS was obtained on day 6 with 1560 mg/L. The other reason is wastewater from their wastewater processing is more suitable for microorganism cultivation because its effluent contains significant beneficial nutrienst and less of toxic compounds and harmful substances that interface with the growth of microorganism In same condition (pH and Temperature) in Acclimatization process can reach 77.45% after 7 days of treatment. After the detention time (18 hours) the results of COD number also greatly decrease with 5 hours recirculation with 8 L/min air flowrate and 86,51 % percentage of COD parameter decreased. This reseach is running in labolatory scale this problem must be recalculate to bring in large scale aplications, but this technology represents and effective, economilly and environmentally friendly process for tofu waste water treatment.

Abstract

Water cleanliness plays an important role as a parameter in observing the quality of water that is suitable for consumption for every human life. This is certainly reflected in the health of a healthier life, but so far it is still low in the water quality that is suitable for community use. This study presents a simple technology to design water filtration using an up-flow system (bottom to up) and finds the effectiveness of the filtration media in reducing the content of iron (Fe) and manganese (Mn) metals in groundwater. Water samples were taken from Bukit Fadiah Asri Housing, Kendari City, and tested using three variations of media composition consisting of fiber, gravel, activated charcoal, black sand, and silica which flowed from bottom to top by gravity. Based on these results indicate that type B media material consisting of gravel, palm fiber, black sand, activated charcoal, silica, and palm fiber with a media thickness of 10 cm has a very good level of effectiveness which can reduce the metal content of Fe by 75% and Mn by 66%. This simple and inexpensive filtration media can be applied to the community to neutralize groundwater turbidity and reduce Fe and Mn metal content because it is used as an adsorption medium for heavy metals in water.

Abstract

Listed as one of the largest waste contributor provinces in Indonesia. The population of East Java in 2020 reached 39 million people, it is the second highest in Indonesia. The increasing number of people accompanied by an increase in income will increase people's consumption in an area and this will cause the increasing amount of waste. If this waste problem is not handled properly, it will have a domino effect as well as degrading the environment. This study wanted to determine the effect of population, real expenditure per capita per year and the number of waste banks on the amount of waste in 2020 in East Java Province. This study uses a comparison of OLS Regression and Robust Regression models. The criteria for selecting the best model use the smallest MAPE, RMSE, and RSE values and the largest R-square value. The results of the partial test and the simultaneous test show that the variables of population, real expenditure per capita per year and the number of waste banks significantly affect the variable amount of waste in East Java with the selected model is the Robust Regression model. The R-square value of the Robust Regression model in this study is 0.8909, meaning that the model's ability to explain the variability of the East Java waste amount data is 89.09 percent, and the rest is explained by other variables not included in the model.
