Abstract

Turtles are one of the reptile animals that can migrate long distances along the Indian Ocean, Pacific Ocean and Southeast Asia. The purpose of turtle migration is to mate, find spawning locations and to find food. Sea turtles have an important role in maintaining the balance of the marine ecosystem. However, the high utilization of sea turtles by humans causes the turtle population to decline. One of the conservation sites that help the government program is in Serangan, Denpasar Bali, namely the TCEC (Turtle Conservation and Education Center), where there are several types of turtles such as the lekang turtle, hawksbill and green turtle. Data collection techniques in this study used observation methods including beach monitoring, relocation of turtle eggs to semi-natural hatchery hatching, hatchling and turtle nesting as well as measurement of turtle length and width carapase curve (CCL/CCW), sand temperature, nest depth, nest diameter, nest distance and nest calculation of the number of eggs to see the success of hatching. The results are turtle conservation activities, ranging from turtle maintenance, hatching of turtle eggs, relocation of eggs, and maintenance of hatchlings to release turtles. The effectiveness given by TCEC to manage and preserve the existence of sea turtles in Indonesia, especially in the Bali region is to provide awareness to the community by not consuming eggs and turtle meat.

Abstract

Shellfish are a fishery commodity in Indonesia with increasing production annually, including a projected 137 thousand tons in 2024. Among the various types of shellfish, blood cockle is one of the most popular among citizens. Only 11-16% of their body is consumable, while the majority of it consists of shells that end up as waste. This waste is generally processed into crafts or animal feed. Blood cockle shell waste contains nitrogen (N) and phosphorus (P), which are necessary for higher and lower plants. This study was conducted to explore the potential of blood cockle shell waste as a growth medium for the microalgae Nitzschia sp. Reduction of the N and P ratio in this study was carried out to increase cell density by limiting nutrients of Nitzschia sp. There were five treatments with four replications in this study: P1 as a positive control (f/2 medium; N/P 8:1), P2 (cockle shell fertilizer medium/CSF; N/P 1,3:1), P3 (CSF+NaNO3; N/P 0,1:1), P4 (CSF+NaNO3; N/P 0,121:1), and P5 (CSF+NaNO3; N/P ratio 0,144:1). The results showed a significant difference (p<0.05) in the population of Nitzschia sp. in P3 with the highest density of 862.500 cells/ml and average daily growth of 275.000 cells/day. Based on this, the lowest N/P ratio limitation showed the best growth in Nitzschia sp. The low ratio indicates the prevention of toxicity in the culture medium. N limitation in this study also showed optimization of N utilization in the metabolic process of Nitzschia sp. N limitation is a strategy to increase the accumulation of nutrients in some microalgae, including Nitzschia sp., as observed in this study.
