Abstract

Pada era kemajuan teknologi saat ini penggunaan Internet Of Things (IoT) Telah banyak digunaka oleh bebagai industri, terutama sebagai media untuk memantau pekerjaan yang sedang dilakukan di industri tersebut. Dengan adanya teknologi IoT ini tidak perlu harus berada ditempat pekerjaan untuk mengamati proses yang terjadi, namun proses monitoring dapat diakses melalui jaringan internet kapanpun dan dimana pun selama tersedia akses menuju internet dengan mengandalkan sensor-sensor aktif yang ada. Pada Tugas Akhir ini di buatlah prototype alat untuk menguji coba pipa jika mengalami kebocoran dapat diketahui dengan menggunakan metode pengukuran tekanan air pada sensor tekanan, metode ini menggunakan sensor tekanan yang dipasang pada pada uji coba pada pipa. Setelah dilakukan pengujian, hasilnya menunjukkan bahwa tekanan pada pipa menurun setelah terjadi kebocoran. Tekanan yang turun dapat diketahui melalui grafik yang ditampilkan pada LabVIEW dengan ketelitian sampai ±10% dari tekanan awal pipa sebelum terjadi kebocoran. Alat simulasi kebocoran ini tidak dapat menahan tekanan diatas ± 20 Psi.

Abstract

Several traditional fishing boats in Sendang Biru, Malang Regency are of the sekoci type using an inboard engine drive system with the position of the propeller shaft installed at an angle to the ship's base line. Based on the theory can reduce the performance of the ship propulsion system up to (2-3)%. In this research, we analyzed how much performance was lost/decreased on the lifeboat type fishing boats installed above. The method we use is the Free Running Model Test by making a model of a traditional fishing boat type of lifeboat with a model size of Loa = 100 cm, Lwl = 80.72 cm, B = 19.7 cm, H = 10.68 cm and T = 5, 08 cm made of aluminum sheet. The Free Running Model Test uses 1 motor and propeller which has a thrust of 60 watts, remote control equipment uses the main component of the NRF24L01 transceiver which works at a frequency of 2.4 Ghz with a range of 240 meters to 1 kilometer with conditions without obstacles and camera equipment drone to record the track. The results of this study show that there is a decrease/loss of performance at a 3-degree angle of 0.24%, at a 5-d. gree angle of 0.49%, at a 10-degree angle of 2.52%, at a 15-degree angle of 4.41% and at an angle of 20 degrees of 6.48%.
