Abstract

The rapid development of the world of technology that covers almost all sides of life has encouraged innovation and human creation to make various tools with automatic work systems. Giving fluids using intravenous fluids is one way to enter fluids intravenously to meet the needs of fluids, electrolytes, drug administration, and feeding. The process of replacing intravenous fluids that has reached the minimum replacement limit must be carried out promptly and quickly, so that there will be no delay in changing intravenous fluids which will result in unstable pressure on the infusion set which will result in blood clots. infusion set which will result in blood clots.In its testing, this tool can display information on the total number of intravenous fluid drops, and the condition of the remaining infusion fluid level on the LCD, as well as an additional display of the number of intravenous fluid drops per minute on theapplications client PC and / or smartphone. Adjusting the position of the mini servo of the infusion tap, can be adjusted when the appliance is not or not connected to the client. The sensor optocoupler used can also detect every drop of intravenous fluid. The reading of the sensor optocoupler used can experience an error by a difference of 100% if the dripping of the intravenous fluid is too slow. This is caused by the drip that is read twice by the sensor because one drop of intravenous fluid is read again after more than 50 milli second.

Abstract

Abstrak – The development of insulation in electric power systems meets the optimal level of reliability. This phenomenon is a challenge in finding new materials to isolate electricity use. One of the insulating materials being developed is an epoxy resin polymer material. This study aims to describe the characteristics of epoxy resin composites added with corncob ash filler as a high-voltage insulation material. The cob ash filler, which is known to contain silica resistant to high temperatures, has good inhibition and can increase mechanical strength. This study was conducted using a direct experimental method in which the isolation of epoxy resin was mixed with corncob ash filler with a mixed variation of 0.5 g, 1 g, 1.5 g, and 2 g. The results show that the more corncob ash filler in the epoxy resin, the faster the failure to penetrate the insulating material made. The breakdown voltage value is 21.64kV on pure epoxy resin insulation material, 10.28kV on a mixture of 0.5 gram corncob ash filler and epoxy resin, 8.93kV on a mixture of 1 gram corncob ash filler and epoxy resin, 7,81kV on a mixture of 1,5 grams corncob ash filler and epoxy resin, and 7,26kV on a mixture of 2 gram corncob ash filler and epoxy resin.

Abstract

Utilization of solar energy in the generation of electrical energy has been widely carried out using solar panels. One example of its use at Tadulako University is public street lighting using solar energy as a source of electricity. The solar panels that have been installed so far have not been effective because of the different tilt angle positions. There are those who can capture the maximum rays of the sun and there are those who cannot capture the maximum rays of the sun and consequently the electrical energy generated is not optimal.The purpose of this study was to determine the effect of changes in orientation and angle of inclination of solar panels on the output power and to optimize the performance of PLTS-based public street lighting in Tadulako University. The method used to determine the effect of the photovoltaic slope on the output power is to measure the short-circuit voltage and current from various forward directions and tilt angles.The influence of the slope and the direction of the front of the photovoltaic installation can be seen that the highest output voltage is 18.82V in the forward-to-west position with an angle of 5˚. The highest short-circuit current is 3.82A in the front-to-west position with a slope angle of 5˚. The highest output power is 47.97W in the front-to-west position with a slope angle of 5˚.

Abstract

Automatic Transfer Switch (ATS) is a device that can move the main power source to a backup power source automatically and quickly when the main power source is interrupted or the supply cuts to the load. In this study, ATS was designed based on the Arduino Nano microcontroller as an automatic control that works based on voltage readings. Using the Arduino Nano microcontroller can facilitate the process of making tools and minimize the use of components. This ATS uses the PZEM-004T voltage sensor module. The voltage sensor module functions to detect and measure the value of the PLN voltage. From the test results, it was found that the time lag between the PLN supply being cut off until the battery was supplying and ready to be loaded was an average of 2.79 seconds. Meanwhile, the time lag when the PLN supply turns on again until the battery supply is cut off and the load supply is again served by PLN is 3.07 seconds on average. Other tests found that in measuring battery resistance with a load of 20 watts, the current obtained is 1.66 amperes with a usage resistance of 27 hours, while when the load is 200 watts the current is 16.66 amperes while the resistance to use is 2.7 hours. The length of battery life is affected by the magnitude of the load.

Abstract

Currently, the energy we use is still using fossil energy. In the future, the need for energy will increase because every year there is a large population growth. If you still use fossil energy and don’t find new energy alternatives, then Indonesia will experience a severe energy crisis and certain places will experience blackouts. One of the efforts so that the wind energy crisis can be minimized is to utilize natural energy that has the potensial to generate energy such as the Wind Power Plant. In this study, planning and simulation of Wind Power Plant were carried out to help reduce the use of fossil energy and help the needs of the community in the Talise Beach area. From the results of the study that the average output of wind turbine production is 1,180/hour winh a maximum production of wind turbines per day of 5,665 kW and the construction system cost (NPC) of Rp. 91,340,660,000. Electrical energy that can be generated from wind turbines by utilizing an area of about 42,021.67 m2 is 10,332,498 kWh/year with a total unfulfilled power of 1,416 kW/year. Lack of power or unmet load can be overcome by the existence of a grid/network.
