Abstract

Skipjack Tuna (Katsuwonus pelamis L.) is a pelagic fish that dominates the waters of the Indian and Pacific Oceans. This fish has unique physical characteristics, including an aerodynamic body, a metallic blue or teal back, and transverse stripes that distinguish it from other species. In Indonesia, skipjack tuna is abundant in the waters of Manado and Maluku. This study aims to determine the types of bacteria present in processed skipjack tuna floss (abon cakalang) based on morphological and physiological characteristics through biochemical tests. This study employs a qualitative descriptive approach conducted in a laboratory setting. Data were gathered through direct observation of samples undergoing various tests and subsequently presented in a descriptive manner. Based on the identification data, 30 bacterial isolates were found in the processed skipjack tuna floss. The isolates were identified macroscopically and microscopically. The findings of the study reveal that the bacteria found in processed skipjack tuna floss, based on biochemical tests and profile matching, are suspected to belong to the Staphylococcus and Vibrio genera.

Abstract

Mosquitoes are vectors of infectious diseases that must be controlled. One of the efforts to control mosquito vectors is by using anti-mosquito products, including anti-mosquito gel spray. Most anti-mosquito products are composed of chemicals that are harmful to health and the environment, so alternative anti-mosquito products made from natural ingredients are needed. The aim of this research is to determine an effective anti-mosquito gel spray formula from a combination of marigold flowers and chrysanthemum flowers. This research uses experimental methods to find the most effective gel spray formulation from different percentages of marigold and chrysanthemum flowers. The variations used are 0%, 2.5%, 5% and 10%. Tests were carried out using 30 adult female mosquitoes. The results obtained through the extraction of marigold flowers showed a yield of 8.922% and a yield of chrysanthemum flowers of 4.560%. The organoleptic test carried out on 10 panelists showed that on average the panelists thought they liked (in the range 4-5) their preference for color and aroma. , texture and reaction after 10 minutes of using the gel spray. The pH test showed that the four gel spray formulas had a pH of 6 or neutral. The results of the homogeneity test carried out with a glass object showed that the four gel spray formulas were homogeneous. The protective power of the 2.5% gel spray formula is 18.01%; gel spray formula 5% is 66.29% and gel spray formula 10% is 88.61%. From these results, it can be seen that a formula with a concentration of marigold and chrysanthemum flower extracts of 10% can be the most effective anti-mosquito gel spray. It is hoped that the results of this research will be useful for society in terms of using mosquito repellent that is environmentally friendly and safe for health.
