Abstract

Ambon City is the most populous city in Maluku, and accessibility is one of the main challenges in meeting health service needs. To overcome this problem, it is necessary to conduct an in-depth analysis of the distance of health facility services in Ambon City.  This study uses a spatial analysis method to map the location and distance between major health facilities such as hospitals, health centers, and clinics throughout Ambon City. The results show that there are diverse spatial patterns in the coverage of health facilities in Ambon City. The spatial pattern of health facility coverage in Ambon City is classified into 5 classes, namely very close covering 7,586, 42 ha, close covering 10,172, 23 ha, medium covering 3,697, 07 ha, far covering 3,473.59 ha and very far covering 7,644, 36 ha. The results of this study also show that Teluk Ambon sub-district has a very large percentage of area at the very close, close and very far reach levels of health facilities compared to other sub-districts in Ambon City, while the area at the medium and far reach levels is dominated by Nusaniwe sub-district which has a larger percentage of area than other sub-districts. This study makes an important contribution to understanding the spatial pattern of health facility coverage in Ambon City and provides a basis for spatially-based decision-making.

Abstract

Buru Island is one of the areas in Maluku Province where forest fires are common. The prolonged summer season, flammable vegetation and the practice of clearing agricultural land and settlements by burning can also trigger forest fires on Buru Island. This research uses fire hotspots in 2019-2023 obtained from the Fire Information for Resource Management System (FIRMS) and analyzed using the Kernel Density method in Arc GIS software. The results showed that in 2019 there were 224 fire hotspots spread across Buru Island, in 2020 there were 30 fire hotspots, in 2021 there were 31 fire hotspots, in 2022 there were 31 fire hotspots, in 2022 there were 32 fire hotspots and in 2023 there were 23 hotspots spread across Buru Island. The results also show that the level of forest fire vulnerability in the very low vulnerability class has an area of 543,868.30 ha or 63.76%, low vulnerability class of 201,449.44 ha (23.62%), vulnerability class of 83,344.31 (9.77%), and high vulnerability class of 24,327.01 ha or 2.85% of the total area of Buru Island.

Abstract

One source that contributes greatly to urban air quality is traffic. The proximity of schools to vehicles will put students at greater risk of exposure to high concentrations of particulate matter. SMP Negeri 1 Jambi City is an education center located in an urban area and adjacent to a busy road. CFD models are good at modeling the movement of pollutants in urban areas by taking into account the influence of buildings. The purpose of this study is to determine the concentration of PM10, PM2.5, PM1, and PM0.1 at SMPN 1 Jambi City based on direct measurement results and CFD modeling results and then see how accurate the modeled PM concentrations are when compared to the results of direct measurements. The results showed that the average concentrations of PM10, PM2.5, PM1, and PM0.1 from direct measurements were 20.66 µg/m3, 11.79 µg/m3, 8.74 µg/m3, and 1.96 µg/m3, respectively, while the modeling results showed lower average concentrations. The ratio of the difference between the measured and modeled PM concentrations is in the range of 11.67 - 233.45% and with the percentage of RMSPE obtained >30% (invalid), where the requirement for a modeling to be valid so that the results can be trusted in explaining the actual phenomenon is when the validity percentage is <30%.

Abstract

Livestock manure which is produced every day can be a problem for the environment if not handled properly. Vegetable waste is generally only allowed to accumulate in the market and immediately disposed of in a landfill without further processing, it can pollute the environment and disturb the aesthetics of the environment. Utilization of organic waste as raw material for renewable energy can be a solution. This study aims to determine the C/N ratio, methane gas production and flames produced from biogas production, as well as knowing the ratio of the ratio of substrate composition and the optimum time to produce the best biogas. This study combined Vegetable Waste (VW) and Cow Manure (CM) with ratio of 90:10, 70:30, 50:50, 30:70, 10:90. Variation of fermentation time was carried out for 5 days, 10 days, 15 days, 20 days and 25 days using a 19 liter volume reactor. The results show that the best ratio of substrate composition in biogas production is VW:CM 70:30 with a C/N ratio of 21.39% and produces 93.78% methane gas and produces a blue flame for 102.35 seconds.

Abstract

Heavy metals are pollutant parameters that contain high toxicity and are dangerous which can accumulate in the tissues of living things. One of the heavy metals contained in wastewater is lead (Pb). This metal is included in the extremely toxic category which can cause health problems. One way to treat waste containing the heavy metal Pb is by bioremediation using microalgae (phycoremediation). In this study, phycoremediation used the microalgae Chlorella vulgaris and Nannochloropsis oculata, as well as a consortium of both. This study aims to determine the ability of each microalga and the consortium of the two microalgae in removing lead heavy metals. The phycoremediation potential was measured based on the ratio of microalgae varied (100:0, 50:50, and 0:100) and the concentration of Pb waste (1, 5, and 10 mg/L) within 14 days on a batch scale. The results showed that the microalgae Chlorella vulgaris in reactor 10B (100% Chlorella vulgaris, 0% Nannochloropsis oculata) was able to remove 85.0% from a concentration of 10 mg/L to 1,5 mg/L.
