Abstract

The Southeast Asian box turtle, Cuora amboinensis, known locally as the “Batok Turtle” is one of the world's most endangered turtle species. Conservation is needed to protect this species from the threat of extinction. Conservation efforts are complex and involve multiple scientific disciplines. This research was conducted in the Ex-situ Conservation area of ​​Bengkulu University, to determine the morphometric variations of adult C. amboinensis and determine the differences between males and females based on body size as a conservation effort. The research subjects were 20 adults (8 men and 12 women) of C. amboinensis. Several morphometric measurements that have been carried out include head width, carapace length, carapace width, curved carapace length, curved carapace width, carapace height, plastron length, plastron width, length of the midline on all plastron scales (sugar, humerus, pectoral, abdominal, femoral and anal), tail length, tail thickness, and body weight. Next, a t test was carried out to determine the morphometric characteristics of male and female C. amboinensis. The results of the analysis show that there are significant differences. C. amboinensis males have greater carapace length, tail length and tail thickness than females. C. amboinensis females have greater carapace height and humeral scale diameter than males.

Abstract

Heavy metals are poisonous materials capable of causing damage to the normal aquatic organisms in the community around the Ketahun River estuary. The entry of heavy metals into the waters of the Ketahun River estuary is allegedly from various activities such as bathing, washing, toilet use, palm oil plantations, coal mining, and the disposal of gold mine waste. This is the background for conducting research to analyze the content of Hg, Cd, Pb, and As in Litopenaeus vannamei in the Ketahun River estuary. The determination of sampling locations was done using a purposive method, and the samples were tested using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The ecology of the river estuary was measured using a thermometer, pH meter, Dissolved Oxygen Meter, and Total Dissolved Solid Meter. The research results were analyzed using a descriptive qualitative method. According to the findings of the study, the metal content in Litopenaeus vannamei exceeds the quality standard with an analysis result of 0.2328 mg/kg, while the quality standard is 0.20 mg/kg, which has health implications. For sediment, the heavy metal that exceeds the quality standard is mercury at 0.5921 mg/kg, while the quality standard is 0.15 mg/kg. The ecology of the river estuary continues to be an ideal environment for living biota.
