Abstract

Penurunan tekanan aliran fluida dalam sistem perpipaan merupakan permasalahan yang sering terjadi di berbagai industri, seperti industri minyak dan gas, industri kimia, dan industri air minum akibat faktor gesekan yang terjadi didalam pipa. Faktor gesekan pada aliran fluida dalam pipa dapat dipengaruhi oleh beberapa parameter seperti densitas fluida, kecepatan fluida, diameter pipa, panjang pipa, dan kekasaran pipa. Pada tahun 2023 alat ukur penurunan tekanan milik Laboratorium Rekayasa Sumber Daya Air dan Pantai di Departemen Teknik Sipil ITS digunakan untuk menghitung besar faktor gesekan pada aliran fluida, namun saat ini penggunaannya masih bersifat analog dan local, hal ini membuat pengguna harus mencatat secara langsung dengan mengamati pressure drop pada sensor, lalu menghitung besar faktor gesekan secara perhitungan manual. Dalam penelitian ini telah dikembangkan sebuah dashboard simulator untuk menghitung besar faktor gesekan pada aliran fluida dalam pipa dimana sensor tekanan dan sensor flow didigitalisasi dan diintegrasikan dengan microcontroller dan mini PC sebagai media data processing untuk mengolah pembacaan sensor tekanan dan aliran agar dapat ditampilkan dalam sebuah graphics user interface. Dari hasil validasi sensor tekanan didapatkan nilai akurasi rata-rata sebesar 98,10% dengan ketidakakuratan 1,9%. Dari hasil validasi sensor flow didapatkan nilai akurasi rata-rata sebesar 98.30% dengan ketidakakuratan 1,70%. Berdasarkan hasil uji kinerja dashboard simulator menggunakan data dummy, dapat dikatakan faktor ukuran diameter pipa dan penurunan tekanan dapat meningkatkan faktor gesekan yang terjadi pada aliran fluida didalam pipa. Dari hasil uji kinerja dashboard pada plant pipa dengan memvariasikan debit air dapat disimpulkan semakin besar debit fluida maka faktor gesekan akan mengecil.

The pressure drop in fluid flow pressure within a piping system is a common issue in various industries such as oil and gas, chemical, and drinking water industries, due to the friction factor occurring inside the pipes. The friction factor in fluid flow within pipes can be influenced by several parameters such as fluid density, fluid velocity, pipe diameter, pipe length, and pipe roughness. In 2023, the pressure drop measuring device owned by the Laboratory of Water and Coastal Resources Engineering at the Department of Civil Engineering, ITS, was used to calculate the magnitude of the friction factor in fluid flow. However, its current usage is analog and local, requiring users to directly observe pressure drop on the sensor and manually calculate the friction factor. In this study, a dashboard simulator was developed to calculate the friction factor in fluid flow within pipes, where pressure sensors and flow sensors were digitized and integrated with a microcontroller and mini PC as data processing media to process pressure and flow sensor readings and display them in a graphical user interface. The validation results of the pressure sensor showed an average accuracy of 98,10% with an inaccuracy of 1,9%. The validation results of the flow sensor showed an average accuracy of 98,30% with an inaccuracy of 1,70%. Based on the performance testing of the dashboard simulator using dummy data, it can be concluded that the diameter of the pipe and the pressure drop can increase the friction factor occurring in the fluid flow inside the pipes. From the performance testing of the dashboard on a pipe plant by varying the water flow rate, it can be inferred that the higher the fluid flow rate, the smaller the friction factor.
