Abstract

Eksplorasi yang dilakukan saat ini sebagian besar dilakukan di atas permukaan air, sedangkan eksplorasi bawah air masih sedikit dijumpai di Indonesia karna berbagai kendala seperti teknologi untuk mendukung eksplorasi tersebut. Pengembangan teknologi bawah air dibutuhkan untuk mendukung kemajuan ekplorasi bawah laut di Indonesia. Tujuan dari penelitian ini adalah melakukan rancang bangun ROUV tipe Penta Tubular untuk mendeteksi material logam di bawah air. ROUV tipe Penta Tubular menggunakan bantuan kamera untuk navigasi, sensor ultrasonik JSN-SR04T untuk mendeteksi jarak objek, dan inductive proximity sensor LJ12A3 sebagai detektor logam. Wahana ROUV dikontrol menggunakan keyboard dengan keywords tertentu dan dimonitor menggunakan smartphone. Pengujian sensor Ultrasonik JSN-SR04T menggunakan 5 variasi jarak, yaitu 20cm, 40cm, 60cm, 80cm, dan 100cm dengan objek deteksi berupa pelat dengan dimensi 35cm x 35cm. Untuk pengujian inductive proximity sensor tipe LJ12A3 menggunakan 3 variasi material yaitu pelat baja, dan pelat alumunium sebagai objek material logam dan pelat PVC sebagai material kontrol. Pengujian dilakukan di dua medium, yaitu di udara dan di bawah air. Berdasarkan hasil pengambilan data uji coba sensor jarak ultrasonik di udara didapatkan persentase kesalahan terkecil 0,06% dan persen kesalahan tertinggi 0,705%. Pada pengujian di bawah air didapatkan persentase kesalahan 0,49% untuk variasi jarak 100 cm. Sensor jarak ultrasonik tipe JSN-SR04 tidak dapat membaca data jarak dibawah 89,75 cm didalam air karena adanya perbedaan kecepatan rambat suara pada medium yang berbeda. Inductive Proximity Sensor dapat bekerja dengan baik pada medium udara maupun air dengan akurasi 100% pada pelat baja, pelat alumunium, dan pelat PVC.

Exploration carried out today is mostly carried out above the water surface, while underwater exploration is still rarely carried out in Indonesia due to various obstacles such as technology to support the exploration. The development of underwater technology is needed to support the progress of underwater exploration in Indonesia. The purpose of this study was to design a Penta Tubular ROUV to detect metallic materials under water. The Penta Tubular ROUV uses camera assistance for navigation, the JSN-SR04T ultrasonic sensor to detect object distances, and the LJ12A3 inductive proximity sensor as a metal detector. ROUV rides are controlled using a keyboard with certain keywords and monitored using a smartphone. Testing the JSN-SR04T Ultrasonic sensor uses 5 variations of distance, namely 20cm, 40cm, 60cm, 80cm, and 100cm with the detection object in the form of a plate with dimensions of 35cm x 35cm. For testing the inductive proximity sensor, the LJ12A3 type uses 3 variations of materials, namely steel plates, and aluminum plates as metal objects and PVC plates as control materials. Tests were carried out in two mediums, namely in air and under water. Based on the results of data retrieval testing of the ultrasonic distance sensor in the air, the smallest error percentage is 0.06% and the highest error percentage is 0.705%. In the underwater test, the error percentage was 0.49% for a distance variation of 100 cm. The ultrasonic distance sensor type JSN-SR04 cannot read distance data below 89.75 cm in water due to differences in the speed of sound propagation in different medium. Inductive Proximity Sensor can work well in air and water medium with 100% accuracy on steel plate, aluminum plate, and PVC plate.
