Abstract

Background: Dengue remains an important Aedes-borne disease, and Aedes aegypti is the primary vector in many endemic settings. The expansion of dengue risk, increasing insecticide resistance, and the need for environmentally acceptable vector-control options support the evaluation of plant-based larvicides. This study assessed the mortality of Aedes aegypti larvae exposed to garlic (Allium sativum) extract. Methods: A true laboratory experiment with a posttest-only control group design was conducted at the Entomology Laboratory, Department of Environmental Health, Poltekkes Kemenkes Palu, in September 2023. Third-instar Aedes aegypti larvae were allocated to six groups: control (0 ppm) and garlic extract concentrations of 0.8, 0.9, 1.0, 1.1, and 1.2 ppm. Each group had four replications with 20 larvae per container (n = 480). Mortality was observed after 2, 4, 6, 12, and 24 hours and analyzed descriptively. Results: No mortality occurred in the control group. Cumulative 24-hour mortality increased from 8/80 larvae (10.0%) at 0.8 ppm to 12/80 (15.0%) at 0.9 ppm, 13/80 (16.25%) at 1.0 ppm, 14/80 (17.5%) at 1.1 ppm, and 16/80 (20.0%) at 1.2 ppm. Conclusion: Garlic extract produced a concentration-related increase in Aedes aegypti larval mortality, but concentrations below 2 ppm did not produce immediate high-level larval control within 24 hours. These low-concentration findings support further studies on sublethal effects, including delayed larval development, impaired pupation, and reduced adult emergence, alongside broader concentration ranges, lethal concentration analyses, and standard positive-control comparisons

Abstract

Background: Pedicab drivers face prolonged sitting, repetitive pedaling, trunk stabilization, and poor seat ergonomics. This study examined associations among posture, working hours, tenure, and LBP at Pasar Inpres in Palu City. Methods: This analytic observational study used a cross-sectional design and was conducted in June 2024 at Pasar Inpres, Manonda Village, Palu Barat District, Palu City. The population comprised all pedicab drivers in the study area, and 51 respondents were recruited via a total sampling approach. LBP was defined as self-reported pain or discomfort in the lower back region at the time of data collection. Sitting posture was assessed using an observation sheet, while working hours, work tenure, and LBP were collected using questionnaires. Data were analyzed using the chi-square test or Fisher’s exact test when appropriate. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated to estimate the magnitude of association. Results: LBP was reported by 38 respondents (74.5%). Non-ergonomic sitting posture was associated with LBP (PR=1.58; 95% CI: 1.08-2.31; p=0.008). Working more than 8 hours/day was also associated with LBP (PR=1.47; 95% CI: 1.04-2.09; p=0.020), as was work tenure of more than 5 years (PR=2.05; 95% CI: 1.21-3.47; p<0.001). Conclusion: LBP was common among pedicab drivers at Pasar Inpres, Palu City. Non-ergonomic sitting posture, working more than 8 hours/day, and work tenure of more than 5 years were significantly associated with LBP. Community-based occupational health programs should prioritize ergonomic sitting education, active rest, stretching, and simple seat support for pedicab drivers.
