Abstract

The ship being analyzed is a Ferry ro-ro 2000 GT sailing from Bali to Lombok via the Lombok Strait crossing route with a distance of 38 nautical miles. Identification of the use of diesel fuel for ship operations is important for ferry vessels, especially in connection with efforts to efficiently use of diesel fuel in ship operations. In solving problems, efficiency analysis is completed by applying technical analytical, correlational-predictive, and comparative methods. The technical analytical method is specifically used to calculate engine characteristics in fuel use, and the correlational-predictive method is used as an approach method to the phenomenon of the relationship between engine characteristics in the use of different fuels in ship operations, in contrast, the comparative method approach will be used to provide a detailed illustration. More complete in a case study of the use of diesel as fuel for the operational main engine of a ferry ship.

Abstract

Glass strain carp (Cyprinus carpio) is highly demanded by farmers due to its delicious, dense meat and fewer spines. To meet the increasing demand for carp, it is necessary to improve the efficiency of aquaculture. The season is known to stimulate one hormone production. The purpose of this study was to determine the effect of season (rainy and dry seasons) on reproductive hormones (follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estrogen, and interstitial cell-stimulating hormone)) in C. carpio glass strain. Idi research was conducted using the descriptive method by rearing fish in different seasons (rainy season and dry season). The results showed that the reproductive hormone of C. carpio strain glass increased during the rainy season. During the rainy season, changes in the environment and water flow patterns are detected by the fish's sensory system. The results showed that the highest hormones in a row were: ICSH hormone (12.82 pg/mL), FSH hormone (male: 3.73 ng/mL; female: 12.10 ng/mL), LH hormone (12.48 MIU/ml), testosterone hormone (9.27 ng/mL) and estrogen hormone (21.84 ng/mL). Further research is needed to observe the growth and abnormality of fish larvae produced in different seasons.

Abstract

Piezoelectrics are materials that can produce electrical voltage when subjected to mechanical stress. This unique property makes piezoelectrics widely used in various applications, such as sensors, actuators, and transducers. One important factor that can influence piezoelectric performance is the tilt angle. The tilt angle is defined as the angle between the piezoelectric surface and the direction of the applied force. This research aims to optimize the tilt angle of immersed piezoelectrics on a laboratory scale. Using the experimental method, this research was carried out using piezoelectric PVDF. Piezoelectric PVDF was chosen because it has good piezoelectric properties and is easy to obtain. Experiments were carried out by applying mechanical force to the piezoelectric PVDF with various tilt angles. Experimental results show that the optimal tilt angle for submerged piezoelectric PVDF is 90 degrees with a value of 7.46196 milliVolts at a flow speed of 1.2m/s. At this tilt angle, the piezoelectric PVDF produces the highest electrical voltage. The results of this study indicate that the optimal tilt angle for sunken piezoelectrics is 90 degrees. This could provide a basis for the development of more efficient and high-performance piezoelectric designs.
