Abstract

Formalin has banned its use as a food additive as stated in the Minister of Health of RI No.033 in 2012, but is still found to foodstuffs containing formalin. To reduce the impact of formalin, deformalinisasi needs to be done, such as immersion in hot water, or in water leri, and soaking and washing ,. This study aims to determine the difference of soaking and washing the concentration of formaldehyde in various foodstuffs. This study is a quasi-experimental, pretest-posttest design The object of research is to Tahu Tabing, salted Sepat fish, and tuna. This research was conducted with four treatment (15, 30, 45, and 60 minutes) for six times repetition. Data was analyzed using ANOVA. The results showed the largest decline formalin after soaking and washing for 60 minutes, decreased levels of formaldehyde in the Tahu of 31.22%, salted Sepat fish by 6.91%, and the tuna amounted to 2.70%. In statistics show there is a difference of soaking and washing the formaldehyde levels in foodstuffs.

Abstract

The presence of water reservoirs as mosquito breeding sites is a major factor in the transmission of dengue hemorrhagic fever (DHF). This study developed an engineering-based tool to manage larval density and prevent mosquito proliferation. Experiments were conducted using 18 water reservoirs made of fiber, concrete, metal, and plastic, both with and without larval traps, with 900 Aedes aegypti larvae as samples. Data were analyzed using univariate and bivariate methods (T-test) at a 95% confidence level. Results showed no significant difference among container materials in supporting mosquito breeding, allowing flexibility in designing water containers for vector control. A light sensor was later integrated to detect larval presence, and a model for community-based application was introduced. The findings confirm that all types of water storage, regardless of material or size, can support mosquito breeding. Incorporating technologies such as light or motion sensors can enhance larval control efforts. This model also serves as a tool for public education on environmental health, emphasizing the importance of household conditions in preventing mosquito proliferation. Further research will refine and implement the model in real-world settings.
