Abstract

This research was conducted with the aim to evaluate the performance of blood glucose of brek fish (Puntius orphoides) in response to stocking density stress. Fish weighing an average of 2.21 g with a weight of 27 individuals were given stocking density stress by inserting them into 9 cylindrical containers of 200.96 cm2 width and 3 L volume of peat water with stocking differently for 72 hours. These stocking density treatments are A (2 fishes/0.02 m2), B (3 fishes/0.02 m2) and C (4 fishes/0.02 m2) with three replicates. Blood glucose collected from 1 fish per container at 72 hours. The preliminary test was conducted to determine the oxygen demand of fish through the oxygen consumption level test which can then be calculated oxygen demand from the fish in accordance with the density used. The average value of blood glucose levels of brek fish that were given the stress of stocking density 2 fishes / 0.02 m2, 3 fishes / 0.02 m2 and 4 fishes / 0.02 m2 tends to be low, that is 53 mg / dL, 52.67 mg / dL and 49.33 mg / dL respectively. The response of blood glucose to stocking density stress results in stocking recommendations for culture brek fish ranging from 100-200 fish / m2.

Abstract

The gas power cycle of a four-stroke combustion engine is obtained from a mixture of diesel injection+compressed hot air as the working fluid, which in this case is taken from a versatile type of diesel engine from all kinds of fishing communities on the north coast of Java Island, it can be said that in general the use of multipurpose diesel engines used as a propulsion engine for fishing boats. A common sight for Pantura fishermen is hot smoke exhaust from the exhaust of a multipurpose diesel motor driving a wooden fishing boat released into the air. Eventually, it becomes a source of air pollution around the ship, especially nitrogen oxides, which are toxic to human respiration; hot smoke waste resulting from the combustion process released through the piston engine exhaust system still contains valuable energy potential in the form of hot gas released by the exhaust which if attempted to heat the hot gas energy before being discharged into the ambient air, the heat energy can be recovered by installing additional heat exchangers as a benefit of heat sources for heat exchange heaters or heaters the result is cold drinking water turns into hot drinking water. Heat balance is the calculation of the heat released in the combustion of fuel+air in the combustion chamber and its utilization in the transfer of cold fluids to hot fluids, which is the heat energy content of explosion in compression combustion engines based on fossil fuels. All heat products of combustion cannot be converted 100% into practical motor work or power; energy transfer is lost from the combustion motor, such as 25%, to cooling water 32%, in the exhaust gas 34%, pumping losses, 3%, losses -friction loss between parts due to lousy machining inaccuracy 6% and radiation to the air environment. A drinking water heater with hot smoke recovery from a versatile diesel motor exhaust driving a wooden fishing boat works by recovering or recovering heat energy from the exhaust gas in the exhaust directly from the combustion process cycle in a piston-type combustion engine. The hot flue gas flow is forced into direct contact with the wall of the heat exchanger tube before exiting the exhaust. As long as the piston combustion motor is running, the hot stream from the exhaust gas flows into the shell & tube heat exchanger shell. This experiment aims to get clean hot water 70OC with a linked cold water mass = 0.0064 kg/s at 28OC. Another effect of this experiment is to control exhaust emissions into the atmosphere from internal combustion engines.

Abstract

Indonesia has cultural diversity that is the pride of the Indonesian people. Indonesian culture has its unique variations and types. However, the development of the times and the era of openness have led to the entry and development of foreign cultures, which are more in demand by some people because they regard foreign cultures as modern. This results in the younger generation preferring a new culture which may be considered more attractive and practical compared to the local culture. This cultural diversity cannot be separated from the creative economy, which is believed to be a new wave in world economic trends after the biotechnology, information and communication era. As a new wave in the world's thought discourse, it raises various pros and cons from various groups and organizations. This research uses a descriptive analysis method. The research results and discussion show that creative economy-based industries can be developed more broadly using a culture-based approach. With its enormous cultural wealth, Indonesia has great potential and opportunity to become the centre of the world's creative economy. Technological developments in the Industry 4.0 era brought about many changes, especially in the creative industry, where there were many creative industry fields whose developments were greatly assisted by the presence of the Industry 4.0 era.

Abstract

The residents of Cangkring Village, Centigi District, mostly work as fishermen. One type of fishing gear used for catching is the dragon trap, with the main target catch being shrimp. This study aimed to determine the composition of the main catch and by-products of dragon traps and determine the effectiveness of the environmental friendliness of using dragon traps operated in Cangkring waters, Cantigi sub-district, Indramayu Regency. The method used in this research is a descriptive method using primary data and secondary data. The composition of the catches obtained during the study was Penaeus merguensis, Metapenaeus monoceros, Scylla spp, and others such as milkfish, eel, and mullet. The total catch during the study was 39.9 kg. The biggest catch was Penaeus merguensis, as much as 22.1 kg. The main catch during the research was Penaeus merguensis, and the by-catch was: Metapenaeus monoceros, Scylla spp, and others. The resulting catch data is 55% main catch and 45% by-catch. A comparison of HTSU with HTS shows that using dragon traps still needs to be environmentally friendly. However, from the aspect of the utilization of the catch, only a small amount is not utilized (discard catch), namely 2.5%.
