Abstract

Krisis energi pada masa ini, membuat kita belajar akan memanfaatkan atau mengembangkan suatu sumber daya energi terbarukan untuk mengurangi penggunaan bahan bakar fossil yang tidak dapat diperbaharui layaknya seperti batubara. Penggunaan sumber daya energi terbarukan ini sangat ramah lingkungan serta bisa meminimalisir dampak buruk dari penggunaan bahan bakar fosil untuk pembangkit listrik. Metode dalam penelitian sistem monitoring energi solar dan wind kincir vertical dengan sistem hybrid berbasis internet of things. Memonitoring kedua pembangkit solar dan wind dengan sistem hybrid mengunakan mikrokontroller Arduino Uno sebagai pengolahan data yang di dapat dari sensor yang digunakan untuk penelitian dan NodeMCU yang digunakan sebagai proses pengiriman datanya, data hasil tersebut dapat dimonitoring melalui smartphone ataupun pc dengan sebuah website.Hasil pengujian sistem monitoring energi solar dan wind kincir vertikal dengan sistem hybrid berbasis internet of things, dapat membaca keluaran yang diberikan oleh kedua pembangkit energi solar dan wind. Sensor yang digunakan dalam pengujian ini Sensor tegangan DC yang memiliki galat rata – rata 0,085%, sensor arus DC ACS712 30 yang memiliki galat rata – rata 0,14%, sensor tegangan AC ZMPT101B yang memiliki galat rata – rata 0.37%, sensor arus AC712 5A yg memiliki galat rata – rata 80.9%, dari ketiga sensor tersebut bisa dikatan pembacaan sensor yang presesi sedangkan penggunaan ACS712 5A dikatan tidak presisi karena arus yang tebaca oleh sensor bisa kurang dari 0A atapun dalam pembacaan mA.

Abstract

Fluid flow rate measurement is important in industries, especially determining fluid flow rate. This process requires a good level of precision and accuracy because it refers to each volumetric's price or custody transfer processor. Many devices are used to measure flow rates, but from some devices, ultrasonic flowmeters are considered, which have more advantages than others. Ultrasonic flowmeters also have some problems, especially in installation, so this research aims to simulate the position of path configuration. The method refers to the weighting process of multi-path configuration and the simulation of track performance, which includes three-factor, hydrodynamic (H), orientation sensitivity (S) and orientation range (T). Each trajectory pattern is rotated 1ᴼ at each angle. In addition, there are also parameter functions that are used to image the profile. The test uses 7 path configurations, so an ideal form is obtained to be implemented. After multiplying weighting factors, the obtained value of hydrodynamic (H) for Area weighting method (1.002), the best value 1. Orientation sensitivity (S), with Area weighting method (0.019), the best result is 0. Meanwhile, with orientation range (T) 1%, with Area weighting method (163,2), the best value is 180.

Abstract

This paper aims to modification the transducer ultrasonic for measuring the distance to develop measure time of flight in the pipe with simultaneous method. To implement the application, we try to develop the microcontroller with one command transmitter and one command receiver in the same time, different from the conventional way, the transmitter and receiver work with consecutively. We try to reduce the delay time in two different transducers. In industrial, the symmetries profile must be ensured the profile always laminar. In this research, we try to use one path configuration. The result with the reference hot wire, we got the 27.76 percentage the difference of result. This is because the hot wire can measure the one path of flow in the one way of dot point.
