Air pollution generated from airport activities has become public concern and the subject of more rigorous government regulations. The Airport Operators are stipulated to control the pollution and for the accountability of air quality that might affect public health. The main objective of this study is to establish a model for the distribution of air pollutants and to predict their concentrations generated by the runway and apron operations at Sam Ratulangi International Airport (Manado) until 2024, in accordance with the airport expansion program. The data was collected in the airport surrounding area in 2018, while the climate data over a span of 10 years, from 2009 to 2018, was obtained from Sam Ratulangi Meteorological Station. The modeling on dispersion of air pollutant gases was developed by the Gaussian Plume Equation. The simulation was performed using AERMOD software, and the results visualized by GIS software. AERMOD software was recommended by the US-EPA to predict the impact of air pollutants. The results predicted that the maximum concentrations of NOx; HC; and CO generated by runway activities modeling in 2024 were 250 μg.m-3; 6.4 μg.m-3; and 87 μg.m-3 respectively. The results also predicted that the maximum concentrations of NOx; CO; and PM10 due to apron operational activities in 2024 were 260 μg.m-3; 892 μg.m-3; and 2.5 μg.m-3 respectively. The model predicted that in 2024 the air pollution at Sam Ratulangi International Airport will remain under the limit as defined in Indonesian Government Regulation No. 22 of 2021. To mitigate the future increase in air emissions due to the increase in airport capacity, the recommendation were proposed in the several areas, which were including operation management, technology, policies and airport regulations, as well as the provision of green area.

Publisher : Universitas Gadjah Mada

In this study, we successfully developed gold nanoparticles capped with histidine (His-AuNPs) for Hg2+ detection using trisodium citrate as the reducing agent. The optimum pH for the detection of Hg2+ by His-AuNPs was 12. The addition of Hg2+ to the His-AuNPs caused the color change from red to black-blue, which is readily detectable by the naked eye. This color change is followed by a decrease in the intensity of the primary Surface Plasmon Resonance (SPR) peak at a wavelength (λ) of 525 nm and an increase in the secondary peak at λ = 650 nm. His-AuNPs effectively detected Hg2+ with limits of detection and quantitation of 1.77 µM and 5.89 µM, respectively. His-AuNPs exhibited good performance for the detection of Hg2+ in waste water collected from a steel industrial facility in Banten Province, with a recovery and a percent relative standard deviation of 115% and 1.02%, respectively.

ABSTRACT: Gajahwong River is one of the 3 rivers that pass through the city of Yogyakarta. There are many activities carried out by the local community around the riverbank, such as settlements, industry, which have the potential to affect the water quality of the river. This research was aimed to evaluate the water quality of the Gajahwong River in the Balérejo-Wirokertèn segment and to determine the water quality status using the STORET, Pollution Index and Water Quality Index (IKA). This study used primary data which were examined at 7 sampling points between the Balérejo Bridge to the Wirokertèn Dam. The research was conducted in the dry season, June 2022. The water quality parameters were DO, BOD, phosphate, nitrate, Cu, Ag, pH, temperature, total coliform (CT) and TDS. Based on the results after calculating the status of water quality using these three indices, the Gajahwong River in the study segment has exceeded the Class II quality standard. In addition, it was shown that there were 5 parameters that most dominantly affecting the status of water quality, namely: CT, Cu, Ag, BOD, and phosphate. These five parameters contributed greatly to the decline in the water quality of the Gajahwong River, particularly in the Balérejo-Wirokertèn segment. Generally, river water quality of Gajahwong river in this study is between marginal to heavily polluted.

Well water used by the community often does not meet quality standards because it contains high levels of iron (Fe) and manganese (Mn). This study was intended to reduce Fe and Mn levels in well water by using filtration technique with activated charcoal media. The effect of hydraulics and backwash dynamics on the efficiency of filtration process was also investigated. The filtration apparatus was made of PVC pipe with the diameter of 4 inches and 120 cm height. The determination of optimum hydraulic conditions of filtration was carried out by varying the size of the activated carbon filter media (8-10, 12-14, and 16-18 mesh) and flow rate (1, 2, and 3 L/min) at the service time of 10 hours. The results showed that the size of filter media has significant effect on removal efficiency of Fe and Mn, with the most effective size was 16-18 mesh with the removal efficiency of 83.33% (Fe) and 93.33% (Mn). The highest head loss value in the filtration column was 0.15 cm, which occurred at the flow rate 3 L/min. Backwash should be performed after filtering process of 35 hours, 44 hours and 55 hours at the flow rate 1 L/min, 2 L/min, and 3 L/min repectively. The single filter design in this study reduced Fe and Mn concentration to meet clean water quality standards.

Bioplastic as an antioxidant and antibacterial packaging has been synthesized from chitosan and sago starch with Black fruit leaves ethanolic extract. The bioplastic synthesis was done by mixing a solution of chitosan, sago starch, glycerol, and ethanolic extract of Black fruit leaves, pouring it into a petri dish, and then drying it in an oven. The bioplastic produced was then characterized using Fourier transform infrared spectroscopy (FTIR). The results show that increasing the weight ratio of chitosan/sago starch increased tensile strength, decreased elongation, decreased thickness, and increased biodegradation time. The addition of ethanolic extract of black fruit leaves reduces tensile strength at a chitosan/starch weight ratio of 4:1, increases tensile strength at a chitosan/starch weight ratio of 1:1, tends to minimize elongation at both Chitosan/starch ratios, tends to increase thickness at a chitosan/starch weight ratio of 4:1, decreases thickness at a Chitosan/starch weight ratio of 1:1, and increases biodegradation time. The best bioplastic formulation in this study found in CS11E1 (weight ratio of Chitosan/starch 1:1, extract concentration 1%), with a tensile strength of 4.71 MPa, elongation of 29.33%, thickness of 0.07 mm, and biodegradation time of 6 days.
