Abstract

Pulmonary Tuberculosis, hereinafter abbreviated as pulmonary TB, is an infectious disease caused by a group of acid-resistant bacteria, namely Mycobacterium tuberculosis. Pulmonary TB is also still a major health problem in Banjar District, South Kalimantan Province, Indonesia. This research is a descriptive study that aims to identify spatial and temporal clusters of pulmonary TB cases in Karang Intan District, Banjar Regency during 2020 – 2021. The statistical retrospective space-time scan with a Poisson probability model was performed to analyzed the data. The spatial units analyzed in this study included 26 villages in Karang Intan District, with a time unit of 2 years, namely 2020 – 2021. The results of the analysis show that there were 3 clusters of pulmonary TB detected and spread across 26 villages in Karang Intan District. There were 2 clusters in 2020, and 1 cluster in 2021. The transmission of pulmonary TB clusters during 2020-2021 was mostly found in areas with relatively medium or high population density. However, the three detected clusters show a P-value > 0,05 which indicates that the clusters are not statistically significant.

Abstract

Tofu production is known to generate large amounts of wastewater containing a variety of organic compounds, chemicals, and potentially hazardous substances. It is very important to apply proper treatment of harmful substances that impact this wastewater. The aim of this study is to explore advanced techniques for treating tofu wastewater by combining multilevel filtration and TiO2 photocatalysis methods. To evaluate the efficiency of the treatment process, influent and effluent parameters, including pH, total suspended solids (TSS), and chemical oxygen demand (COD), are carefully monitored and measured. The results clearly demonstrate the impressive removal efficiency achieved through the combined use of multilevel filtration and TiO2 photocatalysis in treating tofu wastewater. The treated wastewater showed a promising efficiency in pH (100%), a significant decrease in TSS (40%), and COD (72%). the final measurements of pH met the standards set by government regulations, indicating successful remediation of these specific parameters. Even though TSS and COD haven't met the standard limits, each of them shows a very promising efficiency improvement. Towards the end of this study, it is suggested that the combination of these methods holds promise for effectively remediating tofu wastewater.

Abstract

Catfish farming is often faced with the availability of feed which is relatively expensive, so it is necessary to find a solution to support the catfish farming business—provision of sufficient and good quality feed to support fish growth. This study aimed to determine the level of sludge suitable for use as additional feed. Observations were made using the experimental method with a Randomized Block Design (RBD) research design involving one control group and three treatment groups with three repetitions each. The parameters observed were length (p), width (l), and fish weight (b). The environmental parameters observed were water temperature and pH. The results showed that the best sludge presentation to be given as additional feed was in treatment 1 with an average weight between 71.33-73.75 grams, an average length ranging from 18.13 to 22.17 cm, and a width of 3.16. – 3.27 cm. Survival Rate is between 275-78%. Specific Growth Rate (SGR) 1%. Specific Weight Growth Rate (SWGR) is between 2-3%. Based on the results, this study recommends that in the use of biogas output sludge as pellets, it is necessary to improve the quality of feed by adding good nutritious ingredients for catfish.

Abstract

Households with access to wastewater sewerage in Pamotan in 2022 only be 69.9%. This study aims to find out the factors related to household wastewater sewerage ownership in the Pamotan Community Health Center Working Area. This research was an observational analytic using a cross-sectional design. The research population was all families in Pamotan subdistrict villages with the lowest ownership of wastewater sewerage, with a sample size of 90 families. The independent variables are land availability, length of year residence, knowledge, education, and income for the dependent variable, that are ownership of the Waste Water Sewerage. The data were analyzed using univariate and bivariate statistics, employing the Chi-Square test. The results of the study showed that land availability (p=0.04), education level (p=0.018), knowledge level (p=0.003), and income (p=0.00) are related to household wastewater disposal ownership while the length of year residence (p=0.257) is not related to ownership of household wastewater sewerage in the Pamotan Subdistrict. Based on the research results, the length of year residence is not related to household wastewater sewerage ownership because people's old habits that are not good at managing household wastewater result in wastewater sewerage ownership behavior not fulfilling standards.

Abstract

This study investigated the implementation of solar panels in the Dumai Islamic Centre (DIC) Mosque, located in Dumai City, Riau Province, to reduce carbon emissions. The study presents an overview of the significance of solar energy utilization and its potential benefits in the context of mosque buildings. This research was aimed to assess the criteria for selecting the appropriate solar panel type, determine the power output and PV area required for the DIC Mosque, and estimate the carbon emissions reduction resulting from installing solar panels. The study employed a quantitative research design and utilizes the Analytic Hierarchy Process (AHP) to select the most suitable solar panel type. The results reveal that polycrystalline solar panels are the optimal choice based on efficiency, power peak, operation and maintenance, and price criteria. Installing solar panels on the DIC Mosque's roof, positioned at an optimal height, ensures maximum sunlight exposure and energy generation efficiency. Calculations demonstrate a significant reduction in carbon emissions post-installation. The carbon emissions reduction potential is estimated at 57.693 kg CO2 eq per day or 21,057.95 tons CO2 eq per year. This highlights the positive environmental impact of solar energy implementation in the DIC Mosque.

Abstract

Nowadays, most people use eco-friendly bags as alternatives to plastic grocery bags. This comes from the government's strategy of prohibiting plastic bag use and requiring the use of eco-friendly supermarket bags instead. Eco-friendly bags are the most recent developments in supermarket bags made from environmentally friendly raw materials. However, using eco-friendly bags is not the ideal option because it generates new trash clusters as a result of their use and contributes to the impact of climate change. This article examines the effectiveness of using eco-friendly bags in reducing plastic waste and how it relates to SDG 13. This research uses qualitative methods related to analysing the environmental impact of environmentally friendly bags. It was found that bio-based plastics had the lowest GWP values. Several solutions to the problem of plastic bag pollution have been offered, including the development of new biodegradable bag technology, making policies or other incentives encouraging people to reuse shopping bags, and researching eco-friendly bag innovation in Indonesia using LCA.

Abstract

The discrepancy between the use of vehicle fuel types and the vehicle's technical specifications is expected to affect exhaust emissions. This study aims to examine the effect of using four types of fuel with different octane number specifications on two four-wheeled motor vehicles with an EFI fuel delivery system on exhaust gas emission parameters of carbon monoxide (CO), hydrocarbon (HC), carbon dioxide (CO2) and non-emitting gases Oxygen (O2). With a quantitative experimental approach method using the Automotive Emission Analyzer and simple linear regression analysis, the results showed that the use of variations with octane numbers RON 98, RON 92, RON 90, and RON 88 fuels at the same time as variations in engine speed (1000 – 3000) RPM showed an effect on concentration. HC and CO emissions decreased with each increase in the octane number of fuel, RON 92 fuel with the lowest average CO / HC (0.0013% / 0.46 ppm) and RON 98 with the lowest average CO / HC (0.0026% / 0 ppm). The use of RON 92 fuel is more effective and inexpensive to apply to vehicles with an EFI fuel delivery system (with compression of 1:10/10.2) compared to RON 98 fuel which emits higher CO and HC emissions at low engine speed (1000 -1500) RPM.

Abstract

The decline in the quality of waste management has generally started to occur since the prolonged economic crisis in Indonesia. Plastic waste includes inorganic waste, which is currently widely used by industry and households. Therefore, it is necessary to have an alternative recycling process, like converting plastic waste into liquid fuel. The research objective is to utilize LDPE plastic waste (Low-Density Polyethylene) and PP (Polypropylene)in liquid fuelutilizing pyrolysisto determine the effect of using a zeolite catalyst by comparing the results of the pyrolysis process. The investigation took place at the Wonosari landfill in Singkawang, where parameters such as density, viscosity, and color were examined. The pyrolysis results underwent consistency testing through the Mann-Whitney test. According to the study findings, the average physical parameter values for viscosity and density of LDPE pyrolysis liquid fuel were 0.302 cP, LDPE+catalyst was 0.114 cP, with densities of 767 kg/m3 and 737 kg/m3. For PP, the average viscosity was 2.812 cP, and PP+catalyst was 0.248 cP, with densities of 774 kg/m3 and 735 kg/m3. Samples of PP and LDPE with catalysts exhibited lower density values compared to those without catalysts.
