Abstract

One of the endemic turtle conservation areas is the sea turtle conservation area on the coast of Aceh Tamiang Regency, Aceh Province (Batagur borneoensis). This animal is categorized as an endangered animals. The IUCN (International Union for Conservation of Nature and Natural Resources) designated sea turtles as Critically Endangered (CE) in 1996. The distribution of sea turtles is limited because the beach type must be suitable for spawning and survival. The goal of this study was to determine the physical, chemical, and biological characteristics of sea tuntong (Batagur borneonsis) habitat in a conservation area in Aceh Tamiang Regency. In this study, the descriptive method was used. The data collection process was completed. Data was gathered through direct observation in the field. Purposive sampling was used to identify observation stations. There are three research stations: Pusong Kapal (hatching hatchlings), Ujung Tamiang Beach (habitat for adult sea turtles), and Pusung Cium Beach (habitat for sea turtles) (nesting habitat). The study's findings revealed differences in physical, biological, and chemical characteristics at the three stations. It is possible to conclude that the water area off the coast of Aceh Tamiang Regency, Aceh Province, is suitable for sea turtle habitat (Batagur borneoensis)

Abstract

Putak fish (Notopterus notopterus) is a type of fish native to Indonesia which is protected based on Government Regulation Number 7 of 1999. Habitat and environmental factors are one of the factors that influence the survival, morphological and biological characteristics of putak fish. The waters of Rokan Hilir Regency, Riau, are one of the habitats of the putak fish (Notopterus notopterus). This research aims to determine the morphological, biological and physicochemical characteristics of the aquatic environment of putak fish (Notopterus notopterus) in the Rokan River, Rokan Hilir Regency, Riau. The method used in this research is a two-station observation method, identifying research stations using a purposive sampling method. Station 1 is in a community settlement and Station 2 is in an oil palm plantation on the riverbank. Data analysis uses quantitative description with simple linear regression. The results showed that at each station there were 22 fish consisting of 11 male fish and 11 female fish. The results of the morphological characteristics of total length are more dominant in female fish with an average length at station 1 of 211.91 mm and an average of 255.91 mm at station 2 compared to male fish with an average length of 211.91 mm exceeding 178.55 mm at station 1. and an average of 222.00 mm at station 2. Regression analysis shows that the morphology of putak fish (Notopterus notopterus) is in a positive biometric criteria state or at station 2 with TL/SL characters, while the other characters are negative. biomass state. The results of data on the biological characteristics of putak fish (Notopterus notopterus) at station 2 are higher than at station 1. The physicochemical factors of the two stations are differences in temperature, where the temperature at station 2 is higher than at station 1.
