Abstract

Adolescents are a vulnerable group to HIV/AIDS transmission due to risky behaviors and lack of proper knowledge and understanding of HIV/AIDS prevention. One of the prevention efforts that can be done is through health education using audiovisual media. This study aims to determine the differences in HIV/AIDS prevention behavior in adolescents before and after being educated with the IAIC (I'm Aware I Care) method at SMA Negeri 1 Telaga. This study uses a quasi-experimental design with a one group pretest-posttest design. The research sample amounted to 186 respondents who were taken using random sampling techniques. Data analysis was carried out using the Paired Sample t-test. The results of the study showed an increase in HIV/AIDS prevention behavior in adolescents after being educated on the IAIC method. The results of the statistical test obtained a p-value of 0.000 (p < 0.05), which shows that the education of the IAIC (I'm Aware I Care) method based on the Health Belief Model is effective in HIV/AIDS prevention behavior in adolescents at SMA Negeri 1 Telaga. It is recommended that students are expected to increase knowledge, awareness and positive attitudes on HIV/AIDS prevention by utilizing audiovisual media and applying it in daily life.

Abstract

Dug well water is one of the sources of clean water that is used by the community as a water supply facility in daily life. However, the water quality of dug wells often does not meet the requirements, especially in chemical parameters, especially iron content (Fe). High iron levels in water can reduce water quality and increase health and economic problems, so effective, safe and environmentally friendly water management efforts are needed. Corn cobs can be used as activated carbon which acts as a bioadsorbent against iron ion (Fe) pollution. This study aims to test the effectiveness of corn cob charcoal powder in reducing iron (Fe) levels in dug well water with variations in corn cob dosages of 10 grams, 15 grams and 20 grams. The type of true experimental research with a pre-test-post test approach. Iron levels were determined using the spectrophotometry method with three repetitions. Data were analyzed using the Kruskal Wallis test (alpha = 5%). The results of the study showed that the decrease in iron content in the water of the dug well after treatment with a dose of 10 grams with an average value of 0.2341 Mg/L, a dose of 15 grams with an average value of 0.1859 Mg/L, and a dose of 20 grams with an average value of 0.2076 Mg/L This study shows that corn cob charcoal powder is effective in reducing iron levels in dug well water and the dose of corn cob charcoal powder that is effective in reducing iron (Fe) levels in dug well water is the dose 15 grams with a p-value of 0.026 < 0.05, iron content reaches 0.1859 Mg/L and the effectiveness reaches 82%. It is suggested that the community can use corn cob waste as an adsorbent in reducing iron levels and modifying the management of corn cob waste.
