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 hyacinth (Eichonia crassipes) is one type of aquatic plant that has a fast growth rate. As a result, sunlight is blocked from entering the water, so that aquatic biota cannot carry out the photosynthesis process perfectly. This study aims to determine the value of C/N ratio, levels of Phosphorus (P), Potassium (K), pH, and temperature (T) in composting for 16 days with the addition of 200 mL of bioactivator effective microorganism 4 (EM4) in each reactor. Variations of raw materials used are Control Reactor (RK) containing 1.5 kg of water hyacinth; Treatment Reactor 1 (R1) contains 0.5 kg of water hyacinth + 1 kg of cow dung; Treatment Reactor 2 (R2) contains 0.5 kg of water hyacinth + 1 kg of rice bran; and Treatment Reactor 3 (R3) contains 0.5 kg of water hyacinth + 1 kg of cow dung + 1 kg of rice bran. The results showed that the combination of raw materials had an effect on the quality of the organic fertilizer produced. The combination of Treatment 3 (R3) produced organic fertilizer with the best quality, namely C/N ratio = 15.30%, pH = 7.16, macronutrient P = 4.91% and K = 8.36% which met the quality standard requirements. Minister of Agriculture Number 261/KPTS/SR.310/M/4/2019 concerning the minimum technical requirements for organic fertilizers, biological fertilizers, and soil improvement.

Abstract

Water pollution can become dangerous if consumed. River could be polluted with some materials namely heavy metal of chopper (Cu). Heavy metals that are accidentally consumed by human body through the skin surface, some through the respiratory or digestive tract and then accumulate in the body over time. To make an early detection of heavy metal and water quality in water bodies, some animals or plants were used. Several types of crustaceans such as Artemia salina and Daphnia magna or commonly referred to as bio indicators. This study analyze comparison of acute toxicity test that represented by LC50 value of Cu in Artemia salina and Daphnia magna. From the research result it was found that Artemia salina and Daphnia magna gave a toxic effect with LC50 values of 11.78 ppm and 7.87 ppm, respectively.

Abstract

The self-purification capacity is an important indicator for a healthy river. Organic and inorganic pollutants from various pollutant sources, both point sources, and non-point sources, in most rivers in Banjar Regency, cause a decrease in river water quality. This study aims to identify the distribution of river water quality pollution in Banjar Regency as the upstream of the Martapura River and determine the point of self-purification. A sampling of river water using the purposive sampling technique, taking into account the criteria for pollutant sources and the distance of pollution. The results of the concentration values were analyzed using a trend analysis technique, which connected the value of the concentration of pollutant elements with the distance of pollution to identify the distribution of pollution, and to determine the distance of purification. The results showed that the self-purification ability (pH and DO) decreased in concentration at all observation points.
