Abstract

The Aedes aegypti mosquito is a species of mosquito that is known to be the main factor in the spread of Dengue Hemorrhagic Fever (DHF). This outreach aims to educate about the potential of the citronella plant as a natural mosquito repellent. Citronella (Cymbopogon nardus L.) is a plant that contains essential oils consisting of citronellal (27.87%), citronellol (11.85%), geraniol (22.77%), geranial (14.54%) , neral (11.21%). The citronellol compound contained in citronella essential oil has toxic properties that cause dehydration in animals, especially insects. In the Flagship KKN program Batch 50, KUBAR 12 Group, Mulawarman University innovated in making anti-mosquito spray from citronella plants and provided outreach and carried out direct practice with PKK women in Long Iram Seberang Village, numbering approximately 20 people.  The manufacturing process includes drying, cutting, boiling, and mixing with alcohol to maximize the effectiveness of mosquito repellent. The results of this activity show that the resulting spray can last for approximately three days at room temperature and up to seven days if stored in the refrigerator, making it a simple but effective solution in protecting families from mosquito bites. It is hoped that this activity will succeed in increasing public awareness of the importance of maintaining environmental cleanliness and identifying local habits that can naturally reduce the risk of spreading dengue fever

Abstract

This study aims to analyze the effect of artificial feed with different doses of tryptophan amino acid supplementation and determine the appropriate dose of tryptophan amino acid supplementation on the survival and growth rate of tinfoil barb (B. schwanenfeldii). This study used a Completely Randomized Design (CRD) with 4 treatments and 3 replications : P1 (0% tryptophan), P2 (1% tryptophan), P3 (2% tryptophan), and P4 (3% tryptophan). The results showed that the supplementation of tryptophan amino acid to artificial feed did not significantly affect survival and growth, as well as feed utilization efficiency and feed conversion ratio. The supplementation of tryptophan amino acid to artificial feed resulted in 100% survival rate in all treatments. The highest growth rate in total length was achieved in treatment P2 (1%), the highest growth rate in absolute weight was achieved in treatment P2 (1%), and the highest growth rate was achieved in treatment P2 (1%). the highest result for feed efficiency was obtained in treatment P2 (1%), and the lowest result for food conversion rasio was obtained in treatment P2 (1%). The lowest results for total length growth, absolute weight growth, growth rate, and feed efficiency were obtained in treatment P4 (3%), while the highest food conversion rasio was obtained in treatment P4 (3%). Water quality parameters during the rearing period were still considered suitable to support the survival and growth of tinfoil fish (B. schwanenfeldii).
