Abstract

Chlorine Ca(OCl)2 is another compound of chlor that can also remove various kinds of organic and inorganic substances, where these substances have oxidizing and reducing abilities. Two-valence iron (Fe2+) contained in groundwater is caused by the dissolution of water that seeps into the soil, so that the groundwater contains ferrous bicarbonate [Fe(HC03)2], where the water when used will harm the user. This experimental study aims to determine the effect of the dose of chlorine as an oxide in a simple water filtration process on reducing iron (Fe) levels in groundwater using water samples from the borehole complex of the Tanjungkarang Health Polytechnic, Department of Environmental Health. The research was conducted in the laboratory of the Environmental Health Department of Tanjungkarang Health Polytechnic, by making several doses of chlorine treatment in 1,000 ml of raw water, namely P1 = 0.5 gr, P2 = 1.0 gr, P3 = 1.5 gr, P4 = 2.0 gr and P0 without chlorine as a control. The treatment process is carried out by dosing chlorine, stirring (V = 70 rpm, t = 5 minutes), settling (t = 5 minutes) and filtering with a sand filter (0 = 0.1 - 1.5 mm, h = 20 cm) at a discharge of 100 ml / minute. The research results from 5 experiments showed the following experimental results of chlorine 0.0 gr (70.00%); 0.5 gr (84%); 1.0 gr (90%); 1.5 gr (97%) and 2.0 gr (98%). The statistical test used is the analysis of variance, where the hypothesis of the experimental results is rejected, which means that there is a significant difference in the effect of dosage as an oxidizer in a simple water filtration process on reducing iron (Fe) content in groundwater. Further research is needed for maximum results

Abstract

Home industries are small- to medium-scale production units operated within or near households, typically relying on family members or a limited local workforce, with modest capital and without large-scale industrial technology. In furniture production, the main outputs are household items such as chairs, tables, wardrobes, beds, and shelves, while by-products include sawdust and unused wood pieces. Airborne pollutants— particularly wood dust (PM₁₀ and PM₂.₅) from sanding and cutting, along with fumes from paints, solvents, and adhesives—pose significant short- and long-term health risks to workers. This community service project, in collaboration with higher education institutions, aimed to establish long-term control measures. Initial steps involved measuring PM₁₀ and PM₂.₅ concentrations and assessing workers’ blood oxygen levels. Using a descriptive approach, workplace conditions were compared before and after work. Findings revealed a correlation between dust levels and blood oxygen saturation, supporting recommendations for long-term occupational health interventions.

Abstract

Dengue Fever is a viral infection that spreads from mosquitoes to humans. In Susunan Baru Health Center, the number of dengue cases increased by 55% in 2024. Mosquito nest eradication (PSN) with 3M Plus combination, fogging, and community service can reduce the breeding of Aedes mosquitoes and reduce Dengue Fever. The purpose of this study was to determine the relationship between 3M plus behavior and Dengue Fever in Susunan Baru Health Center, Bandar Lampung City. This method is quantitative research, case control study. The sample was 128 samples, 64 case respondents and 64 control respondents (1:1). Case samples were taken with total sampling technique, control samples were taken with purposive sampling technique. Data analysis was conducted with chi-square test (α)=0.05. Conclusion There is a significant relationship between closing water reservoirs (p value = 0.000), draining water reservoirs (p value = 0.003), recycling used goods (p value = 0.000), changing flower vase water (p value = 0.000) and sprinkling larvicide powder (p value = 0.036) with the incidence of Dengue Fever in the Susunan Baru Health Center Working Area, Tanjung Karang Barat Subdistrict, Bandar Lampung City.
