Abstract

Introduction: The diseases caused by some vectors, such as dengue, malaria, chikungunya, and filariasis are still being an issue. In 2019 the Larva Free Index (LFI) in Indonesia showed a percentage of 79,2% and this number has not reached the target of the ABJ program of > 95%, with 138,127 dengue cases recorded. In order to prevent mosquito larvae, biological control is used with mosquito’s natural enemy. This research aims to identify the differences abilities between the Betta Fish and the golden cichlid as the mosquito larvae of Aedes aegypti control. Methods: This type of research was quasi-experimental with a completely randomized design (CRD). The data collected by observation. Repetition/replication in this study was 18 samples. The data analysis used an Independent T-Test with a confidence level of 95% (α = 0.05). Result and Discussion: Betta fish has ability to prey on 20 larvae within onehour, total amount of larvae eaten in 9 times repetition was 175 larvae (96.4%). The golden cichlid has the capability to prey on 18 larvae within one hour, with the total amount of larvae eaten 9 times repetitions was 146 mosquito larvae (80.6%). Betta fish had a higher predation ability than golden cichlid (p value = 0.000). Conclusion: There was a difference in the ability of Betta fish and golden cichlid to control Aedes aegypti mosquito larvae (p value = 0.000). Betta fish was able to be more effective predators of mosquito larvae than golden cichlid.

Abstract

Introduction: Laying hen farming constitutes a vital agricultural subsector that plays a significant role in meeting the demand for animal-based food products. However, livestock production is also recognized as a major source of atmospheric ammonia emissions. Ammonia has a negative impact on public health and the environment. This study aims to analyze the environmental health risks of exposure to ammonia gas around laying hens farms. Methods: The research was carried out using a descriptive design method of environmental health risk analysis (EHRA). The population in this study was the community around the laying hen farm with a sample of 95 respondents. Measurement of ammonia gas was carried out using a spectrophotometer using the Indophenol method based on SNI 19-7119.6-2005. Air samples were taken at three points. Results: The results of this study showed that the largest concentration was 0.00807 mg/Nm3 and the lowest was 0.00711 mg/Nm3. Based on an analysis of environmental health risks, the RQ value at the highest concentration was 0.00466 for the adult population and 0.00618 for the child population. Conclusion: The conclusion of this study is that exposure to ammonia gas in the adult population weighing 55kg and the child population weighing 25kg around the laying hen farm in Darsono Village is still within safe limits for a frequency of 350 days/year for the next 9 years. The advice that can be given is that the farm concerned needs to carry out livestock waste management as a source of ammonia emissions in laying hen farms.
