Abstract

Batik wastewater comes from the dyeing process of batik fabrics. Reactive dyestuffs are synthetic dyes that are often used. Reactive dyes that are often used are Methyl Orange (MO) and Methyl Blue. Only 5% of the dyestuffs are used in batik dyeing, the remaining 95% will be discarded. The content of dyestuffs used causes batik liquid waste to have alkaline, cardiogenic properties, difficult to decompose and contain high organic substances. So that batik wastewater treatment is needed before it is discharged into water bodies, coagulation is one of the waste treatment methods that can be used. The purpose of this study is to determine the decrease in pollutant parameters in the form of TSS and color by the biocoagulant of dried luffa cylindrica. This study was conducted by varying the dose of coagulants and pH of coagulants with a stirring speed of 200 rpm for 2 minutes and a stirring speed in the flocculation process of 60 rpm with a time of 40 minutes. The highest removal of color content and Total Suspendid Solid (TSS) occurred in the use of biocoagulant at a dose of 3500 mg / l pH 6, namely 76% and 75% respectively.

Abstract

The need for water must be directly proportional to the supply of clean water. The government through PERUMDA Drinking Water through the Sustainable Development Goals (SDGs) program in point six regarding clean water and adequate sanitation is trying to meet the target by 2030. In the distribution of clean water, the hydraulic system is an important aspect because flow and pressure influence the continuity of the hydraulic system. happen. This research was carried out using a quantitative analysis method with a case study of the distribution network development project carried out by PERUMDAM Tirta Dharma Purabaya in Sumberejo Village. Distribution network modeling was carried out using EPANET v.2.2 software to analyze discharge, flow velocity, pressure and pressure loss in the distribution network system on an ongoing basis for the next 10 years as well as evaluating and optimizing the water sources that will be used. Based on the EPANET v.2.2 simulation results in 2022, it shows that there are 24 pipes with problematic speeds, 21 junctions with problematic pressures, and 3 pipes with problematic headloss gradients. So recommendations for improving the distribution network in Sumberejo Village are made in accordance with the planning criteria of Minister of Public Works Regulation Number 27 of 2016 to optimize the performance of the distribution system for the next 10 years. The maximum head loss in the distribution network in 2022 will be 14.26 m/km and improvements are recommended so that by 2032 it will be 7.10 m/km.

Abstract

Production activities in the palm cooking oil and margarine industry generate emissions, both from combustion and non-combustion processes. This analysis aims to determine the results of the emission dispersion model from immovable sources on ambient air quality using AERMOD Software in the area around the Industry. The AERMOD modeling method is carried out by using generated emission load data, topography and meteorological data of activity locations for the last 10 years with air pollutant parameters measured including Particulates (TSP), Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2). After running the data, the results of the air emission dispersion modeling show that the highest concentration of emissions is located in settlements that are to the southeast of industrial emission sources. With the concentration of each parameter, namely for SO2 it is at 3.65 mg/Nm3 at a distance of 537 meters from the emission source, the NO2 parameter is at 5.98 mg/Nm3 at a distance of 497 meters, and the particulate parameter is at 1.31 mg/Nm3 with a distance of 498 meters. Distance can affect the emission concentration, namely the farther the distance from the emission source, the lower the emission concentration. Modeling using AERMOD shows that the dispersion of emissions on ambient air quality around the palm oil industrial area still meets the quality standards which refer to Government Regulation Number 22 of 2021 Appendix VII concerning Ambient Air Quality Standards.

Abstract

Wastewater generated from the operation of the Eco Resort and Marine Tourism activities originates from domestic activities. Wastewater from domestic activities is treated at the Sewage Treatment Plant (STP) and discharged into the sea. This research aims to provide a deeper understanding of the spatial distribution patterns of wastewater parameters (COD, BOD, and Ammonia) from Eco Resort and marine tourism activities in the Flores Sea. This study was conducted during the west season in January 2021, followed by modeling using MIKE 21 EcoLab, to determine the magnitude and distribution patterns of pollution in the Flores Sea. The modeling results show that outfall 3 significantly influences the increase in COD and BOD concentrations, especially during peak tide conditions and when the tide is receding. Another factor causing an increase in COD and BOD values is the proximity of the outfall to the wastewater discharge point. Based on the simulation results, the increase in ammonia concentration is influenced by environmental factors and tidal changes. During low tide conditions, the seawater current from the Flores Sea flows northward, transporting wastewater from outfalls 1 and 2 to the north, resulting in increased ammonia concentrations in that area.
