Abstract

Particulate pollution increases with population and activity. Likewise, the city of Surabaya is the 2nd largest metropolitan city in Indonesia based on its population. PM2.5 is a fine particulate that can pose a greater health risk than PM10. This research aims to identify PM2.5 ambient air quality in the city of Surabaya by analyzing daily fluctuations in PM2.5 and calculating an index to be able to categorize ambient air quality in the city of Surabaya. The analytical method used is a quantitative observation method that involves analyzing fluctuations in the distribution of PM2.5 over 24 hours and 7 days and calculating ISPU and NAAQS. The results of the observations showed an increase in PM2.5 particulates at certain times, and the highest spike in PM2.5 levels occurred on Saturday. Based on ISPU and NAAQS calculations, there are differences: according to ISPU, the ambient air quality in Surabaya is classified as moderate, while according to US-EPA standards, the ambient air quality in Surabaya is classified as unhealthy for sensitive groups.

Abstract

The Sidoarjo Regional Public Company (Perumda) is a regionally owned business entity that participates in managing and providing clean water which will be distributed to the people of Sidoarjo Regency. The Sidoarjo Drinking Water Company, especially the Krian IPA, uses the main channel to supply raw water from the Mangetan Canal which passes through seven sluice gates to irrigate 17,583 Ha of rice fields. The series of air treatment installations at Perumda Air Minum Sidoarjo are coagulation units, flocculation units, sedimentation units and ultrafiltration membranes. However, not all technology can be implemented optimally due to considerations of costs and Perumda personnel. The problem is that the ultrafiltration membrane unit at Perumda Air Minum Sidoarjo is not activated. Therefore, the aim of the research is to determine the ineffectiveness of ultrafiltration membranes at Perumda Air Minum Sidoarjo in terms of technical aspects, namely the quality of water resulting from membrane processing in 2016-2020. The results of the research on the technical aspect, namely data on water quality parameters for turbidity and color for 2016-2020, have complied with Minister of Health Regulation Number 2 of 2023 for drinking water quality standards, the rejection percentage for turbidity parameters was 69.39%. -95.48%; the percentage of color parameter rejection was 43.60% -61.6% with the resulting flux value decreasing.

Abstract

The fisheries goods known as processed snakehead fish products are susceptible to spoilage when stored for extended periods of time. Using a vacuum sealer during the packing process is one way to prevent processed snakehead fish items from spoiling. As a result, we will be designing a vacuum machine in this research. The goal of the Vacuum Machine's design and packaging is to increase the processed snakehead fish product's selling value while also prolonging its useful life. It is anticipated that the machine under design would be capable of packing tasks that can be finished quickly and affordably. There are several pieces to this machine, such as the vacuum motor, and vacuum clamp.

Abstract

This research aims to explore the potential of dragon fruit waste as a source of biohydrogen through anaerobic fermentation. The research background highlights the urgency of renewable energy and identifies the potential for dragon fruit waste. Using experimental methods and involving dragon fruit waste and cow dung, this research includes evaluation of waste characteristics, inoculum pre-treatment, medium preparation, biohydrogen production, and analysis of results. The research results show that Total Solids (TS) has increased every day, indicating that there is still high decomposition of organic material which affects biohydrogen production. The test results showed that the TS percentage experienced a significant increase in solids content reaching 96% on the seventh day, while the VS percentage increased from 19% on the first day to 80% on the seventh day. The increase in Volatile Fatty Acid (VFA) concentration and hydrogen production on the sixth day illustrates the potential of waste as a renewable energy source. The conclusion of this research states that dragon fruit waste has the potential for biohydrogen production of 4 mL from a substrate volume of 500 mL or around 0.8%.

Abstract

Environmental pollution by heavy metals, including chromium, is a common issue, particularly in the batik industry. Chromium, although essential, can become a hazardous substance in its +6-oxidation state. This research aims to investigate the use of spent bleaching earth as an adsorbent to remove chromium ions (Cr) and color from batik industry wastewater. The study consists of two main phases: a preliminary study and the main research phase. In the preliminary phase, the initial characteristics of batik wastewater were tested, and a coagulation-flocculation-sedimentation process was performed to reduce parameters that could interfere with the adsorption process. The primary adsorbent material used was spent bleaching earth, with a comparative adsorbent consisting of pure bleaching earth and powdered activated carbon. In the main research phase, the treated wastewater was flowed into an adsorption reactor. Variables varied included flow rate (7 mL/minute and 15 mL/minute) and adsorbent mass (30 grams and 50 grams). The analysis revealed that lower flow rates and greater adsorbent masses increased adsorption efficiency. Adsorption capacity was calculated using the Thomas mathematical model. Spent Bleaching Earth proved to be effective in adsorbing chromium ions (Cr) and color, with an adsorption capacity exceeding 85%.

Abstract

Domestic and industrial waste has been identified as containing many heavy metals as indicators in water bodies. The research aims to analyze the heavy metal quality of Surabaya river water and predict its quality as sustainable raw water. This research was located in the Surabaya River in the Karangpilang IPAM intake segment. The research method uses a forecasting approach based on primary data using a purposive sampling method and laboratory tests. The results showed that the heavy metal concentrations ofCr = <0.0117, Cu = <0.0090 and Pb = 0.001-0.010 did not exceed the quality standards based on class I classification of PP No. 22 of 2021 concerning Implementation of Environmental Protection and Management. The concentrations of heavy metals Cr and Cu are still lower than the detection limit of the test equipment, so forecasting is only carried out on the heavy metal Pb. The simulation results for the next 10 years still get results that meet the quality standards, but when compared with the actual ones with MAPE validation, there are several values that exceed the standards with very badforecasting levels.

Abstract

The Kappaphycus alvareziiseaweed in Pulau Panggang, Kepulauan Seribu, DKI Jakarta, has experienced a significant decline in production. From 1984 to 2000, production ranged from 8,106 to 36,625 tons, contributing 25.61% to the total production in the Thousand Islands. However, in 2021, production drastically decreased, reaching only 254 tons in 2019. This study focuses on identifying the factors causing the decline in production. Analysis of water samples indicates that oil and fat pollution in the aquaticenvironment exceeds the established standards, surpassing 1 mg/L, potentially harming marine life, including seaweed. Field observations reveal the fact that the seaweed's ability to survive is within a specific timeframe (seaweed lifespan) that never reaches the harvesting age due to consistent occurrences of death.SEM-PLS analysis shows that both physical and chemical parameters influence the seaweed lifespan by 43.9%.Statistical analysis supports the hypothesis that physical parameters are not significant(p>0.05), while chemical parameters, indicating oil and fat pollution, significantly affect seaweed lifespan(p<0.05).This research provides profound insights into the causes of the decline in Kappaphycus alvarezii seaweed production in Pulau Panggang

Abstract

Addressing the problem of increasingly complex urban household waste requires a multi-aspect approach. Bioethanol fermentation from pineapple peel juice is interesting research to carry out because pineapple peel is one of the fruit wastes that has the potential to be used as raw material for bioethanol production. Disposal of pineapple peel waste can causeenvironmental problems because this waste can become a source of water and air pollution if not managed properly. Therefore, processing pineapple peel waste into useful products such as bioethanol can help reduce the environmental impact of waste disposal. This research discusses the effect of nutrient concentration on bioethanol production in the fermentation process from pineapple peel. The nutrients used include urea and NPK (Nitrogen, Phosphorus, Potassium) which are added during fermentation with varying nutrient concentrations of 11.25 g, 22.50 g,and 33.75 g. This research also considered the initial fermentation conditions, namely the sugar contentof pineapple peel juice of around 4 Brix and a pH in the range of 5.5 to 6.0. Fermentation results are measured in the form of bioethanol content, with production targets of 6%, 7.5% and 9%. Higher nutrient concentrations tend to support better yeast growth and higher ethanol production. However, it should be noted that a proper balance between nutrient concentrations needs to be achieved to avoid negative impacts such as overstimulation and the production of undesirable compounds.
