Abstract

Pemantauan laju korosi pada struktur baja di lingkungan laut hingga saat ini umumnya masih dilakukan secara manual dan inspektif, baik melalui metode destructive seperti pengambilan sampel material, maupun metode non-destructive (NDT) seperti inspeksi visual atau pengukuran potensial di lapangan. Seluruh pendekatan tersebut membutuhkan kehadiran teknisi secara langsung di lokasi dan tidak memungkinkan akuisisi data secara kontinu dan real time. Keterbatasan ini menyulitkan proses deteksi dini terhadap peningkatan laju korosi yang dinamis, khususnya pada struktur baja seperti jacket pile di Semi Permanent Jetty (SPJ). Penelitian ini bertujuan untuk memberikan alternatif simulator sistem monitoring laju korosi jarak jauh secara real-time menggunakan metode pengukuran resistansi material dengan memanfaatkan kombinasi sensor Tegangan DC dengan sensor Arus INA219 yang terintegrasi dengan ESP32 dan module LoRa sebagai sistem komunikasi jarak jauh. Proyek Akhir ini menggunakan spesimen pipa baja yang umumnya digunakan sebagai material jacket pile SPJ. Pengujian korosi spesimen pipa baja pada proyek akhir ini, didapatkan rentang nilai resistansi spesimen 1 pada rentang 7,63 - 8,72 Ohm dan nilai laju korosi 0,00191 sampai 0,00218 mmpy. Sedangkan spesimen 2 mendapatkan nilai rentang resistansi 6,10 - 5,48 Ohm dan nilai laju korosi 0,00272 sampai 0,00303 mmpy. Hasil penelitian ini menunjukkan bahwa sistem monitoring laju korosi mampu menghasilkan nilai laju korosi yang tepat pada spesimen pipa baja sebagai representasi material jacket pile SPJ. Selain itu, proyek akhir ini juga dapat digunakan untuk mengevaluasi efektivitas proteksi material berupa coating dan Alumunium cathodic protection (SACP) dengan membandingkan nilai laju korosi antar spesimen.

Corrosion rate monitoring on steel structures in marine environments is still predominantly conducted manually and through on-site inspection methods. These include destructive approaches such as material sampling, as well as non-destructive techniques (NDT) like visual inspection or potential measurement in the field. All of these methods require technicians to be physically present on site and do not allow for continuous or real-time data acquisition. Such limitations hinder early detection of increasing corrosion activity, especially on steel structures like jacket piles in Semi Permanent Jetties (SPJ). This research aims to propose an alternative system for remote real-time corrosion rate monitoring using a material resistance measurement method. The system utilizes a combination of DC voltage sensors and INA219 current sensors integrated with an ESP32 and LoRa module for long-range communication. This final project uses steel pipe specimens commonly employed as jacket pile material for SPJ. Corrosion testing
of the steel pipe specimens revealed that Specimen 1 had a resistance range of 7.63–8.72 Ohms and a corrosion rate of 0.00191 to 0.00218 mmpy. Specimen 2 showed a resistance range of 6.10–5.48 Ohms and a corrosion rate of 0.00272 to 0.00303 mmpy. The results of this study indicate that the corrosion rate monitoring system is capable of producing accurate corrosion rate values for steel pipe specimens representing the jacket pile material of the SPJ. Additionally, this final project can be utilized to evaluate the effectiveness of material protection methods, such as coating and aluminum sacrificial anode cathodic protection (SACP), by comparing the corrosion rate values between different specimens.
