Abstract

Family felidae, the order of carnivores, includes Felis Domestica. Domestic cats can be kept as pets, wild domestic cats typically cluster in close proximity to human settlements. Feral domestic cats typically make use of human food resources that have been left over. As a result, the purpose of this research is to determine the variety of domestic cat behaviors in the area of Gampong Meurandeh and Gampong Teungoh in the Langsa Lama District of Langsa City in Aceh. The method used to observe the average daily behavior of domestic cats is by using survey methods and scan sampling carried out at 15 minute intervals. There were three categories of the observed cat's daily behavior: affiliative behavior, self-preservation, and negative behavior. Based on the study's findings, differences in daily behavior based on Gampong differences and time differences were dominated by self-care behavior, then affiliative behavior and then negative behavior. The morning and afternoon feeding times of the cats and humans in the two villages were not significantly different.

Abstract

Langsa City is a city located in the province of Nangroe Aceh Darussalam with an area of 262.41 km2 with a population of 165,890 people. Meurandeh Village is one of the villages located in Langsa city, precisely in Langsa Lama. Meurandeh is one of the places that produces plants from the Tradescantia genus. This research aims to identify and differentiate the stomata of three types of plants from the Tradescantia genus. The method used in this research is a qualitative method with observational data collection techniques. The results of this research show that the three types of plants from the Tradescantia genus have three neighboring cells and a tetracytic type of stomata. Of these three types of plants, there are differences in the shape and structure of the stomata.

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.
