Abstract

COD level of Pojok Laundry’s wastewater did not meet the quality standard regulated in the Special Region of Yogyakarta Regulation No. 7 of 2016 (>150 mg/l) which was 442.5mg/l. This study was aimed to decrease COD levels using the tray aerator method. Manganese greensand with a diameter of 0.25 mm and a thickness of 2.4 cm/tray was also added. This type of research was a quasi-experimental with Nonequivalent Control Group Design. The sample in this study amounted to 50 samples with 5 treatments (30, 45, 60, 75, and 90 minutes), and 5 repetitions. Samples were taken from the washing machine outlet pipe. There were two groups, where the control group was only given aeration and the treatment group was given aeration with the addition of manganese greensand. Data analysis using the two-way ANOVA test showed that there was an effect of time variations on the decrease in COD levels (p<0.05), there was a difference in the average of decreased levels of COD between the control and treatment groups (p<0.05). The average decrease in COD levels after treatment with a time of 30, 45, 60, 75, and 90 minutes, respectively, was 195.7 mg/l (28.80%); 299.0 mg/l (43.63%); 372.1 mg/l (54.79%); 438.3 mg/l (64.61%); and 513.8 mg/l (75.45%). The decrease in COD levels increased with time. The conclusion of this research was that tray aerator with manganese greensand addition can reduce COD levels with the highest reduction up to 76.69% (90 minutes treatment, detergent usage: 30 g).

Abstract

Introduction: Pulmonary tuberculosis is ranked the second health problem in the world, including Indonesia with reasonably high mortality rates. This study examined the association between the ventilation, physical condition, and the prevalence of pulmonary tuberculosis in the working area of the Sragen Primary Healthcare Center. Methods: This study used a case-control design and purposive sampling to select 40 patients with positive smear pulmonary tuberculosis as the case group and 40 subjects with negative smear pulmonary tuberculosis as the control group who lived in the same area. Results and Discussion: Ventilation volume per hour (p = 0.007; OR = 3.889; 95% CI = 1.533–9.868), ventilation area (p = 0.014; OR = 3.462; 95% CI = 1.379–8.691), lighting intensity (p = 0.007; OR = 3.955; 95% CI = 1.546–10.114) and a humidity level (p = 0.001; OR = 5.762; 95% CI = 2.065–16.079) were associated with the prevalence of pulmonary tuberculosis in patients of the productive age group who attended the Sragen Primary Healthcare Center. The results of the multivariate analysis conclude that ventilation (OR = 5.900), humidity level (OR = 8.414), and occupancy density (OR = 0.113) had joint influences with a significant contribution of 41.3% to TB prevalence. Conclusion: House' ventilation and humidity are the main factors contributing to the incidence of pulmonary tuberculosis in the working area of Sragen Primary Healthcare Center.

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

Tubercolusis is a disease that attacks the lungs. The disease is caused by the bacterium mycobacterium tubercolusis. The bacteria mycobacterium tubercolusis can be killed by antibiotics. However, continuous use of antibiotics can cause bacterial resistance. So we need to find new drugs that can prevent multi-drug resistant tuberculosis. This study aims to determine the antibacterial activity of MDR TB from soft coral symbiont bacteria Lobophytum sp. There were 6 bacterial isolates obtained from soft coral Lobophytum sp. One isolate from Lobophytum-associated bacteria were successfully screened for antimycobacterial against MDR TB bacteria. PLO2 was found to inhibit the growth of MDR TB (MDR TB strain SIRE and R). Based on the results of identification with PCR, soft coral symbionts of PLO2 was closely related to Virgibacillus marismortui with homology of 99%.

Abstract

Dengue hemorrhagic fever has been a public health concern in Cilongok District evident by a sharp increase in its cases in the last two years. This study aims to analyze the relationship between physical, biological, and social environmental factors, as well as the behavior of 3M Plus, with the incidence of dengue hemorrhagic fever in Cilongok District, Banyumas Regency. The research followed a quantitative approach of observational analytics with a case-control design. A total of 60 respondents were involved, consisting of 30 cases and 30 controls that were selected using neighborhood-matched controls based on a residential distance of less than 100 meters. Data analysis was carried out using chi square test and logistic regression. The results of the study show a cumulative increase in dengue cases from 26 cases in 2023 to 126 cases in 2024. Spatial analysis showed an uneven distribution of cases with high concentrations in densely populated areas, especially Langgongsari Village, Pageraji Village, and Panusupan Village. Indoor temperature was significantly associated with the incidence of dengue (p = 0.038; OR = 3.500), as well as air humidity (p = 0.039; OR = 3.455). Biological factors measured through the House Index (p = 0.398; OR = 1.902) and Container Index (p = 0.398; OR = 1.902) do not indicate a meaningful relationship. In social environmental factors, the habit of hanging clothes was significantly related to the incidence of dengue (p = 0.004; OR = 5.675), as well as the absence of gauze wire in house ventilation (p = 0.008; OR = 5,231). The other 3M Plus behavioral variables did not show a significant relationship. This study shows that the incidence of dengue fever in Cilongok District is influenced by microclimatic conditions in the house and specific behaviors that increase the chances of human-vector contact. Efforts to control dengue need to integrate ventilation and humidity management of the house with targeted behavior change interventions, especially reducing clothing storage in the room and increasing household physical protection Keyword: dengue hemorrhagic fever, environmental factors, 3M Plus behavior

Abstract

There are several locations in DKI Jakarta which have the potential become breeding places for Anopheles spp larvae. The aim of this study was to analyze environmental vulnerability to the presence of Anopheles spp. larvae with malaria cases using a geographic information system approach. This study was an observational study with a cross sectional design. This study was carried out in March – June 2023 in North Jakarta City, DKI Jakarta. The sample consists of data from all malaria patients from 2020-2023 in North Jakarta. The global positioning system coordinates were taken at the addresses of malaria patients. In addition, data on the presence of Anopheles spp. obtained from larval surveys conducted in Cilincing and Penjaringan Sub-Districts and the coordinates for the habitat of Anopheles spp. larvae. The GPS points obtained were then used for spatial analysis. The distribution of malaria cases was random, while the distribution of Anopheles larvae was dispersed. Buffering zone >1000 m from the breeding site indicated that it does not have the potential in malaria transmission due to malaria patients were at a long distance from the breeding site of Anopheles spp. and flight distance of Anopheles spp. not exceeding 1000 m
