Abstract

The equipment of experiment and research of oceanography at the Physics Laboratory of the Faculty of Mathematics and Natural Sciences, Bengkulu University are still very limited of type. One of the oceanography equipment is a current meter to measure the temperature and speed of ocean currents. This equipment has limited data recording which is still manual so that it is prone to human error in its measurement. In an effort to overcome the limitations of the current meter above, in this study a temperature and ocean current velocity data logger was developed. This study aims to develop a data logger and test its effectiveness which was carried out in July – November 2021 with four stages. The first stage is design, including hardware design and software design. The second stage is the manufacturing stage, namely the manufacture of data logger hardware following the system block diagram and software development using Arduino software following the system flow diagram. The third stage is the testing stage, which includes the process of testing system performance, calibration and field testing. The fourth stage is evaluation, namely evaluation of system performance, accuracy of measurement results, and refinement of data loggers. Comparative test of the results of temperature measurements using a data logger and current meter experienced a difference between 0.1 - 0.8 oC. While the current velocity measurement using a data logger and current meter shows a difference between 0.3 – 1 m/s. The data logger has been successfully developed and works well, but its accuracy still needs to be improved by replacing the water velocity sensor with a higher sensitivity.

Abstract

The power supply as a voltage source with a DC (Direct Current) output voltage or direct current is often used for electronic equipment, both office equipment and household equipment (Imam Saukani, 2020). In using the power supply, the output voltage is selected and high accuracy is required to obtain the output voltage that suits the user's needs. Often times, the power supply used in the practicum does not produce the right output voltage. The purpose of this study is to determine the value of the difference in the output voltage error generated after first determining the voltage value to be used at no-load using a digital multimeter and an analog multimeter as a comparison. After measuring the output voltage of the power supply, the correct voltage value is obtained in each practicum, measurements made at the same time can give definite results of the value of the output voltage of the power supply, the relatively small difference in results ensures that the power supply is in good condition, the output voltage of the power supply is measured using the measuring instrument with repeated measurements 7 (seven) times at each predetermined voltage and obtained a difference of 0.01V – 0.02V. After taking measurements using digital and analog multimeters, it can be concluded that measurements made before the practicum by measuring the output voltage of the power supply can help get the correct voltage value in each practicum, measurements by comparing measuring instruments at the same time can provide definite results of the resulting voltage value by the power supply, the difference in the results obtained is relatively small so as to ensure that the power supply is in good condition, the power supply can be used on loads or electronic equipment that requires a DC voltage source (Genta Subni Ananda Putra, et al, 2020). Practicum can be done well by measuring the output voltage of the power supply. This difference in output voltage results is what the author uses as research material for scientific writing which aims to find solutions to existing errors.

Abstract

Vocational Colege required a lot of practice. The practice of Refrigeration System, one of practice is charging refrigerant and vacuuming the refrigeration system. Because it was carried out by several groups, what happened was that the refrigerant that had been put into the system was wasted during the process of vacuuming the other groups. This causes an impact on the environment and the health and safety of the practitioner. The type of refrigerant used by the practitioner is the type of HCFC-22 or R-22, which has begun to be limited in use because it is less friendly to the environment and causes damage to the ozone layer on earth. One of the efforts to overcome the large amount of refrigerant that is released into the environment is to manufacture a refrigerant recovery device. This tool is used to take refrigerant from the system into the recovery tube prior to the practice of vacuuming, so as to minimize the wasting of refrigerant into the surrounding air. This study aims to determine how efficient the use of refrigerant is in the Refrigeration System practicum using a refrigerant recovery device. The method used is to compare the amount of refrigerant that enters and leaves during the vacuum process, with and without a refrigerant recovery device. From the results of the research, the efficiency values of refrigerant saving for practice using refrigerant recovery tools were 65.22%; 65.00%; 66.67%; 77.78% and 88.24%. So it can be concluded that the use of refrigerant recovery is able to save the use of refrigerant in the practice of the Refrigeration System.
