Abstract

Tinea pedis is a type of superficial mycosis. Tinea pedis is a dermatophyse that is most often found in humans and is usually called water fleas. Lack of maintaining cleanliness and wearing closed shoes is one of the factors that causes Tinea pedis. Tinea pedis usually affects adults who work in wet or humid places, such as car and motorcycle washers, garbage collectors and farmers. When doing activities, the average farmer uses boots for too long. However, some farmers who do not wear boots while working experience itching on the soles of their feet. This research aims to determine the prevalence of fungal contamination that causes water fleas (Tinea pedis) in farmers in Tegalharjo village, Banyuwangi Regency. The population of this research are 30 farmers in Tegalharjo village, while the research sample Is skin scrapings between the toes of the farmers. Then the sample obtained is directly examined by using a microscope and 10% KOH reagent. The results shows that the farmers who are contaminated with the fungus that caused Tinea pedis are 6 people with a percentage (20%) and 24 people who are not contaminated with a percentage (80%). The incidence of infection Tinea Pedis among farmers in Tegalharjo Village, Banyuwangi Regency is also influenced by the duration of working in a day and the habit of wearing boots.

Abstract

Culex quenquefasciatus is a mosquito that acts as a vector of filariasis disease. In Indonesia filariasis is still one of the endemic diseases. This proves that the handling of vector Culex quenquefasciatus is still not done optimally. One way that can be done to control mosquito vectors one of them is to use larvacide. Larvacide which is widely used today is still synthetic. Although very efficient in causing mosquito mortality, larvacide synthesis harms the environment and can cause vectors resistance. Then another larvacide alternative is needed that is effective and does not cause negative effects. Plants can be a choice of larvacide from nature. The study aims to find out the potential of the water extract of bay leaves and papaya leaves in killing the larvae of the Cx. quenquefasciatus mosquito as well as the value of LC50 after 24-hour observation. The type of research used is experimental research. The concentration of the water extract of bay leaves and papaya leaves used is 10%, 30%, 50%, 70%, and 90% with trhee times replication. LC50 is calculated using the Finney formula (1971), the calculation is carried out using application SPSS statistical version 26. Based on the research conducted, the value of bay leaf water extract LC50 = 62.89 g/ml and papaya leaf water extract LC50 = 45.10 g/ml. So based on the LC50 value, ita can be concluded that papaya leaf water extract is more effective in causing mortality Cx. quenquefasciatus compared with bay leaf water extract.
