Abstract

This study aims to analyze the concentration of particulate matter, specifically PM2.5 and PM10, in Makassar City during the period from 2019 to 2023. Air quality in Makassar has become a growing concern due to the significant impact of air pollution on public health, especially among vulnerable groups such as children, the elderly, and individuals with chronic illnesses. The method used in this study is a secondary data analysis obtained from the Makassar City Environmental Agency (DLHD). The results show fluctuations in PM2.5 and PM10 concentrations, with a significant decline during the COVID-19 pandemic (2020–2021) and a sharp increase in 2022–2023. The lowest annual average concentration of PM10 was recorded in 2021 at 10.54 µg/m³, while the highest occurred in 2023 at 16.28 µg/m³. For PM2.5, the lowest concentration was recorded in 2021 at 11.05 µg/m³, and the highest in 2023 at 17.83 µg/m³. Seasonal factors such as rainfall, along with economic recovery and the increase in motor vehicle use, are identified as the main contributors to changes in particulate concentrations. These findings highlight the need for more adaptive air pollution control policies.

Abstract

Carbon monoxide (CO) is a hazardous gas produced by motor vehicles and industrial activities, with increasing concentrations in the air. Makassar, as a center of economy and urbanization, faces major challenges related to air quality. Efforts to reduce CO emissions are important to improve air quality and public health in Makassar City. The purpose of this study was to identify fluctuations in CO concentration trends in Makassar City during the period 2019 to 2023, to determine whether there was an increase, decrease, or a certain pattern and to see the factors that influenced it. The results showed that the CO concentration analyzed based on annual data showed a significant increase in CO emissions related to transportation, industrial, and urbanization activities. The analysis showed that urbanization, the number of motor vehicles, and weather patterns affected changes in CO levels. The CO concentration in Makassar showed an annual fluctuation of 1072.88%, which is considered very high, especially due to the large spike in CO concentration in 2022.

Abstract

The increasing demand for ultrasonography (USG) phantoms for training and equipment calibration highlights the need for effective and affordable local alternatives. This study investigates two base materials water and oilas anechoic phantom media through a laboratory-based experimental approach. Phantoms were constructed by placing two test objects a gasoline filled straw and a piece of Styrofoam into separate containers filled with each medium, then scanned using the Mindray DP-10 ultrasound device. Measurements of object diameter and depth were conducted five times to assess precision and image quality. Numerical data and visual outputs were analyzed comparatively to evaluate acoustic characteristics, image clarity, noise level, and stability. The findings reveal notable differences in imaging performance between the two materials, reflecting the influence of acoustic impedance and viscosity on phantom effectiveness in USG applications.

Abstract

Raw water treatment into clean water that meets quality standards is a significant challenge. One method of water treatment is using membrane filtration. In this study, membrane filtration utilized chitosan (shrimp shell) and PVA with activated carbon variations. Activated carbon possesses a large pore structure, allowing various contaminants to be trapped. The membranes were tested for flux and permeability using a dead-end flow system. Meanwhile, the quality of the filtered water was evaluated by measuring TDS and pH. The research results show that the chitosan (shrimp shell) and PVA membranes with activated carbon addition exhibit good performance, as seen from the flux test, permeability test, and membrane performance in water treatment. Specifically, M2, with a 1% activated carbon mixture, demonstrated better flux and permeability values compared to other membrane samples. For M2, flux values of 1.26 L/cm².hr, 5.75 L/cm².hr, and 6.10 L/cm².hr were obtained with increasing pressure applied to the membrane at 0.5, 1, and 1.5 Bar, respectively. It also had a permeability value of 4.11 L/cm².hr.Bar, which is higher than other membranes. Water quality test results also showed good outcomes, indicated by a decrease in pH and TDS values.

Abstract

This study aims to examine the mechanical characteristics of briquettes made from a mixture of coconut shells, corn cobs, and cow dung with tapioca adhesive. Briquettes were tested based on their mechanical properties for density using a vernier caliper and for compressive strength and hardness using a Universal Testing Machine (UTM). Samples were made in different mixture compositions with particle sizes of 60 mesh and 100 mesh. The results showed that variations in particle size and material composition significantly affected the quality of biobriquettes. Biobriquettes with a particle size of 100 mesh have higher density, compressive strength, and hardness than 60 mesh particles. The material composition with a ratio of 44:44:12 produced the best characteristics with a density value of 0.94 g/cm³, compressive strength of 9.32 kg/cm², and hardness of 41.10 HB. This study proved that biobriquettes meet the criteria as an environmentally friendly alternative fuel and have the potential to reduce biomass waste while providing efficient renewable energy.

Abstract

Isodosis contour analysis using surfer type 21 software has been conducted in the radiology installation of Labuang Baji Hospital Makassar to determine the safest distance for radiology medical personnel while in the X-ray aircraft area. Measurements were carried out before and during exposure to a water phantom using an X-ray aircraft with a surveymeter. Radiation exposure rates were measured at 8 track locations in the X-ray aircraft room, consisting of 16 points located on the track (A, B, C, D, E, F, G, H) at 1 m and 1.5 m heights. The processed data showed that the highest radiation exposure dose was in the E-1 track (in front of the X-ray plane), which was 0.001791 mSv with a radiation dose exposure rate of 43.320 mSv/hour for a height of 1 m and 0.001228 mSv in the A-1 track for a height of 1.5 m with a radiation dose exposure rate of 29.7997 mSv/hour. The isodose contours also show variations in the number of passes and different colors for each radiation exposure dose value. The findings of this study indicate that the radiation exposure dose is 0 mSv at a distance of more than 2 m from the X-ray plane, so the radiologist is within safe limits to perform radiodiagnostic procedures.

Abstract

Performance evaluation of diagnostic radiology modalities strongly supports the quality of radiation and images for diagnosis. This test requires certain materials as a substitute for human objects to avoid excessive radiation. Phantom as one of the object replacement media has been directed according to the characteristics of the tissue. This study aims to obtain the radiation response of artificial bone tissue made from eggshells with the addition of rice bran, resin and catalyst, in 4 (four) mixture compositions. Test variations were carried out by changing the X-ray tube voltage (80 kV, 100 kV, 120 kV and 140 kV) to obtain CT-Scan images and analyzed using Radiant DICOM software. The results showed that the Hounsfield unit (HU) value of the artificial bone phantom corresponded to the HU value range of real bone organs, which is between 100 and 700 HU. This value affects the analysis of the resulting image resolution in the form of SNR and CNR values, in the range of (8.07-37.38) and (14.98-28.20), respectively. Conclusion Artificial bone tissue phantom made from eggshells and rice bran has the potential as a testing medium because it corresponds to the characteristics of human bones, especially in adulthood, and has the potential as a testing medium.

Abstract

Geothermal energy presents a promising alternative for electrical power in Indonesia, especially in regions like Papua, where current power plants heavily rely on fossil fuels. As Papua anticipates an increase in energy demand due to regional expansion, exploring renewable energy sources becomes crucial. Mosso Village in the Muara Tami District of Jayapura City is known for its geothermal potential, evidenced by the presence of hot springs in the area. To assess this potential, a geophysical study was conducted focusing on the geothermal system in Mosso Village. This study utilized 3D modeling of subsurface structures through the gravity method. It incorporated both primary and secondary data, with secondary sources including GGMplus gravity model data, digital elevation model (DEM) data, and geological maps. Primary data comprised rock density samples representing surface densities of geological units in the study area. The GGMplus gravity data was central to the analysis, which involved processing, correcting, and modeling these data to identify geothermal features. The 3D modeling revealed a high-density zone at a depth of 1200 m beneath the hot spring source, interpreted as an indication of hot rock or magma intrusion, suggesting it as the geothermal heat source. Additionally, the model identified a low-density area around the hot spring, interpreted as a sedimentary groundwater basin in the geothermal system of Mosso Village. This study highlights the potential for utilizing geothermal energy in the region and provides valuable insights into the geothermal system’s structure.

Abstract

An effective way to address the plastic waste problem is by minimizing the use of non-biodegradable plastics. One approach is to develop biodegradable plastic packaging that is environmentally friendly. This research used Goroho banana peel starch, this type of banana is used because it has good potential with a starch content of 80.89%. In this research, variations in ZnO concentration of 1%, 2%, 3%, 4%, and 5% w/w were conducted. This research aims to determine the characteristics of physical properties of bioplastics with the addition of ZnO. This research uses a laboratory experimental method through several processes, namely goroho banana peel starch extraction and bioplastic manufacturing. The results indicated that varying concentrations of ZnO significantly influenced the physical and biodegradation properties of the bioplastic products. The physical properties of the bioplastics produced have met the Indonesian National Standard (SNI) for water uptake of 21.5% and biodegradation of 60 days. FTIR results show that the functional groups of bioplastics are identical to the constituent functional groups, namely starch, so that their properties resemble the properties of their constituents, which are easily degraded. The most optimum bioplastic is BPZ 2 with the addition of ZnO at 2% w/w, which produces water uptake of 1.859% and degradation time of 12 days.
