Abstract

The Kapuas Kecil River is a river that becomes the lifeblood of the people of Pontianak in supporting their lives. It is raw water source for Municipal Waterworks, industry, fisheries, agriculture, animal husbandry, tourism, and transportation. The variety of activities carried out on the banks of the Kapuas Kecil River contributed to the occurrence of pollution by heavy metals such as Cd. Currently, the Kapuas Kecil River flow is already crowded with industrial shipbuilding activities, which are one of the contributors to Cd metal pollution in the waters. This study aims to identify the source of Cd pollutants and determine the concentration of Cd in the Kapuas Kecil River. Sampling was carried out in October at four sampling points at low tide, then compared with the allowable Cd concentration according to PP 22/2021 which is 0.01 mg/L, and the status of water quality was determined by the pollutant index method. Based on the results of the study, the Cd concentration was still below the quality standard with a value of >0.001 mg/L, and the water quality status met the quality standard.

Abstract

The brick industry has the potential to create a source of pollution in the form of dust which is harmful to the environment and workers health from the burning process. This study aims to determine the risk factors and analyze the relationship between dust exposure and symptoms of respiratory disorder in workers. This study used the total sampling technique to choose a sample of 75 participants for an observational study with a cross-sectional approach. The results showed that the average total dust particulate levels at 13 points was 1748.47 µg/Nm3 and the average inhaled dust content in 75 respondents of 4.56 mg/m3. The results of the analysis showed that the variables associated with symptoms of respiratory disorder were inhaled dust levels (p=0.023), working period (p=0.040), length of exposure (p=0.032), and use of personal protective equipment (p=0.015). Workers in the brick sector in Tegowanuh Sub-District may have respiratory symptoms more frequently depending on their exposure to amounts of inhaled dust, working period, exposure duration, and use of personal protective equipment. During the work process, it is advised to use personal protective equipment as a mask to prevent the onset of respiratory problems.

Abstract

Brantas River is a raw clean water sources that flow through Malang City. The Brantas River water is polluted due to discharging of untreated wastewater, causing a decrease in river water quality. According to these problems, exploring water resources through Brantas River water treatment is essential using Free Water Surface Constructed Wetland (FWSCW) which aims to analyze the performance and improve the water quality of the Brantas River using these wetlands. The research was conducted on a laboratory scale with control treatment and FWSCW with aquatic plants such as Pistia stratiotes, Echinodorus palaefolius, and Heliconia psittacorum. The results showed that pH and temperature were stable, with values between 7.63 to 8.53 and 23°C to 27°C. The removal efficiency of FWSCW and control in reducing turbidity was 99.53% and 98.55%, respectively, and TDS reduction was 0.56% and 2.84%, respectively, for control and FWSCW. The water quality has met the 2nd class of the water quality standards based on Government Regulation of the Republic of Indonesia No. 82 of 2001. At the same time, the efficiency of reducing BOD concentration was 89%. The results show that the FWSCW system can be used as a secondary treatment system to produce clean water.

Abstract

Tanjungpura University is one of the State Universities in West Kalimantan. Waste management in the Tanjungpura University area still applies the old waste management paradigm. Waste management in the Tanjungpura University area still applies the old paradigm of waste management, which has an impact on environmental problems, because waste management has not been handled optimally. Therefore, it is necessary to plan a waste management system with a new paradigm that integrates the 3R concept (Reuse, Reduce and recycle) with the Waste Bank. The research data were obtained through in-depth interviews and field sampling using the SNI-19-3964-1994 method for 8 days. The results of the study show that waste generation in 2035 will be 39,035 l/day. The projected results of waste generation and waste composition form the basis for waste management system planning. The waste management system includes sorting waste at the source, designing segregated containers, designing waste collection cars, processing organic and inorganic waste, and designing 3R-based Waste Processing Site which is integrated with the Waste Bank. This plan is expected to help develop Tanjungpura University with a Green Campus concept.

Abstract

This research proposes to find out the present state of the water's purity in Tukad Badung through an examination of the Pollution Index (PI) adopted from the methodology presented by the Water Quality Index (WQI), which was presented by the Indonesian Ministry of Environment. A series of water samples were taken at three river flow points in the Denpasar City area, representing the upstream, middle, and downstream areas. The water quality parameters were determined based on the characteristics of domestic wastewater pollutant sources that are identified in watershed areas. In accordance with Regulation 22 of the Government of 2021 concerning quality standards for river water used for drinking water, the average concentrations of Total Suspended Solid (TSS), Ammonia, Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) parameters have exceeded quality standards. Meanwhile, the oil and grease parameter, as well as detergents, still meet quality standards. The PI at three monitoring points was obtained at 2.41 – 4.27, categorized as lightly polluted. In the future, efforts to deal with water pollution are critical to meet the downstream water quality standards used as drinking water.
