Abstract

Aquaculture is a fishery activity that produces fish with human intervention to gain profit. Freshwater fish is one of the fishery cultivation commodities that have economic value. Langsa City is one of the cities that has developed freshwater aquaculture. The village in Langsa city that has tried to cultivate freshwater fish is the village of Meurandeh Teungoh. This activity aims to identify the morphology and morphometry of freshwater fish species located in Meurandeh Teungoh Village, Langsa Lama District, Langsa City, Langsa District, Aceh. The methods used in this research are quantitative. Based on the research results, it was found that there were 8 types of freshwater fish consisting of the claridae, pangasidae, anabantidae, cyprinidae, and cichlidae tribes.

Abstract

Yogurt is the oldest dairy product and is quite popular almost all over the world. Yogurt comes from pure cow's milk. Butterfly pea (Clitoria ternatea ) often referred to as butterfly pea or blue bean is a distinctive flower with a single petal in purple, blue, pink and white. Researchers wanted to see the effect of adding butterfly pea flower extract (Clitoria ternatea) to cow's milk yogurt (Bos taurus). This study employs a quantitative approach as its method. A quantitative approach was used to understand what the research subjects experienced from the color, taste, aroma and texture of the yogurt. The results of the study found that the addition of butterfly pea flower extract (Clitoria ternatea) at different levels had an effect on the organoleptic characteristics and texture of yogurt. The best practice produces organoleptic characteristics of taste (slightly sour), color (light blue), texture (slightly thick) and aroma (typical of yogurt).

Abstract

Nila fish (Oreochromis niloticus) is one of the leading commodities in freshwater fish cultivation in Indonesia is a freshwater fish commonly found in Indonesian waters. Media will be the main obstacle in cultivating tilapia on idle land (land that cannot be operated). Different water media influence the physiological responses of tilapia fish. The purpose of this activity is to determine the effect of differences in freshwater, brackish water and sea water media on the physiological response of tilapia fish. The parameters of this research are differences in water media, physical factors of the media, survival of tilapia fish, respiration rate of tilapia fish, mobility of tilapia fish, weight of tilapia fish and flexibility of tilapia scales. This study used quantitative methods with a completely randomized design (RAL). The collection technique makes observations. Data were analyzed using ANOVA with a significance level of 5%. The results of this study show that differences in the aquatic environment significantly affect the physiological response of tilapia. Where in sea water the fish mortality rate is quite high compared to fresh water and brackish water.

Abstract

Peudawa Beach is one of the beaches in East Aceh or more precisely East Aceh Regency. Insects are  part of the coastal ecosystem. Insects are found in almost all ecosystems. Information on the insect diversity of the banks of Peudawa  has not been thoroughly studied. The purpose of this study is to see the diversity of insect species in Peudawa beach. The method used in this study is an exploratory descriptive research method. In this study, three techniques are used in data collection  technique, namely well drop technique, insect net technique and manual sorting technique. The Shannon-Wiever diversity index (Hand#039;) is used in the data analysis technique. The results of this study show that the insect diversity of Peudawa coast, East Aceh District belongs to the moderate diversity index category, which is influenced by the physical factors of the surrounding environment. The result was 22 insect species in 3 research  stations.
