Abstract

Cermin Beach is one of the beaches that has an abundant level of diversity and abundance of biota, one of which is the level of diversity of gastropods which have many roles as key organizations in food networks in waters. Gastropods as organisms that live in waters are very sensitive to changes in the water quality where they live. This research was conducted on November 25 2023 with the aim of knowing the types of Gastropods found at Cermin Beach, Paya Dua Village, Peudawa District and to determine the structure of the Gastropod community related to individual density, relative abundance, frequency of presence, diversity, evenness, and similarity of species by applying a survey method with primary data collection carried out using the Line Transet method, namely by walking along the intertidal zone along the specified transect line. The results show that at Cermin Beach in Paya Dua Village, Peudawa District, 46 species of gastropods were found with different numbers at each station. The relationship between physical and chemical factors in Cermin Beach waters also influences the diversity of Gastopoda.

Abstract

Betta fish (Betta sp.) is a type of ornamental fish that has unique characteristics compared to other ornamental fish. This research was carried out in November 2023 with the aim of finding out the behavioral patterns of Betta fish when exposed to different types of light. This research used a quantitative method with a (RAL). The results of the research showed that there were changes in behavior in Betta fish (Betta sp.) that had been given different colored lights. The reason why fish are attracted to light is, among other things, because fish have positive phototaxis properties which cause fish to be stimulated and attracted to gather at light sources. In this research, it can be seen that the movement of betta fish moves away from the light source, because the light coming out of the lamp will become hot if it is turned on for too long. If this goes on for a long time, it is feared that the fish will become bored and also experience stress.
