Abstract

Cuttlefish is widely consumed by the public because it has a soft meat texture and high nutritional content. This makes the cuttlefish one of the mollusca that is a source of protein in addition to squid and octopus. The disadvantage of cuttlefish is that it is prone to deterioration in quality. One effort to prevent quality deterioration in cuttlefish is by freezing. The purpose of the implementation of this Field Work Practice is to decide the production process of frozen  cuttlefish  (Sepia officinalis) using the Contact Plate Freezing (CPF) method and to know the obstacles that occur in the production process. Field Work Practice was held in PT. Karya Mina Putra, Rembang, Central Java. The stages of the frozen cuttlefish  production  process  at  PT.  Mina Putra's work includes the reception of raw materials, weighing I and sorting, labeling I, weighing II, washing, pan preparation, freezing, glazing, packaging and labeling II, storing in cold storage, and loading. The freezing process is carried out by the Contact Plate Freezing (CPF) method for 6 hours until the temperature reaches -40 ° C. The obstacle in the production process of frozen cuttlefish is there was a Contact Plate Freezing (CPF) machine damage and there are some employees who do not apply the SOP applied to prevent cross-contamination of the product.

Abstract

The freshwater aquaculture fishery sector in Indonesia has the potential to be developed through extensification and intensification. The problem in aquaculture is diseases that infects cultivated organisms, one of which is caused by bacterial infection. Bacterial infection can cause huge losses to cultivation activities, including death which results in economic losses. The purpose of this study is to identify the A. salmonicida and E. ictalury in live fish that will be exported from DI Yogyakarta. The method of examining bacteria used is conventional which consists of isolation, purification, presumptive test, biochemical test, and identification. The results showed that all live fish samples (koi, gouramy, goldfish, catfish, and eel) were not infected with A. salmonicida and E. ictalury. This shows that all live fish are in a healthy condition and suitable to be exported of DI Yogyakarta.

Abstract

Indonesia is known as one of the world's marine biodiversity centers with its rich coral reefs. Coral growth depends on environmental conditions, which in reality do not always remain due to disruptions originating from nature or human activities. The growth of coral reefs in a sea water is strongly influenced by the quality of its waters such as chemical oceanographic factors namely salinity, pH, DO, nitrate and phosphate. The data collection was carried out twice in September and November 2019 in Damas Waters, Trenggalek, East Java. The waters of Damas Beach are located in Karanggandu Village, Watulimo District. The purpose of this study was to determine the condition of coral reefs in Damas Waters, to determine the effect of water quality on artificial reefs in chemistry in Damas Waters and to determine the relationship of quality parameters of chemical waters with artificial coral reefs in Damas Waters, Trenggalek, East Java. The sampling method is done by purposive random sampling that is determining the sample with certain considerations. The location points used by 20 stations are spread, namely on artificial reefs, natural coral reefs, open seas and the area around the harbor. Measurements made include in situ water quality with a multiparameter measurement tool, namely AAQ. The results obtained that in all stations found good water conditions for the life of coral reefs, and also the analysis of the relationship of each parameter and coral reefs influence each other.

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.
