Abstract

Pada penelitian ini dibuat suatu alat simulator radar yang menggunakan komponen utama mikrokontroler arduino nano dan untuk mendeteksi serta mengukur jarak obyek yang tertangkap simulator radar menggunakan sensor  ultrasonic. Sensor ultrasonic yang digunakan untuk menangkap obyek dikopel dengan motor DC servo agar dapat digerakkan kearah kanan dan kiri dengan simpangan sudut 360°. Permasalahan yang terjadi dengan putaran 360O adalah mengatasi terlilitnya kabel sensor ultrasonic dalam mekanis radar tersebut. Sehingga dibuat dua buah lempengan yang akan menghunbungkan lempengan yang statis dan lempengan yang dinamis dengan empat jalur untuk koneksi ke terminal sensor. Visualisasi obyek yang tertangkap radar (sensor ultrasonic) akan ditampilkan pada layar komputer dengan visualisasi grafik dan memberikan tanda beep setiap menangkap obyek yang ada di depan sensor. Simulasi ini dibuat untuk mendeteksi benda sampai pada jarak 40 cm, dengan membuat skala 1:10 sehingga 40 cm sama dengan 4 meter. Perangkat lunak yang digunakan memvisualkan obyek yang tertangkap radar Arduino menggunakan Processing karena software ini sangat mudah komunikasi antar platform. Hasil pengujian  alat ssudah sesuai dengan tujuan, tetapi masih memiliki rata-rata kesalahan dalam melekukan pengukuran jarak sebesar 0,225.

Abstract

Proses pengabutan bahan bakar pada Injector mesin induk kapal sangat menentukan efisiensi pembakaran. Ketidaksempurnaan proses ini dapat disebabkan oleh tekanan bahan bakar rendah, penyumbatan nozzle, atau kualitas bahan bakar buruk. Penelitian ini dilakukan di kapal MV. SPIL RUMI untuk menganalisis penyebab dan solusi dari ketidaksempurnaan tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan metode observasi langsung, wawancara, dan dokumentasi selama praktik laut di MV. SPIL RUMI. Teknik analisis menggunakan diagram fishbone untuk menemukan penyebab utama permasalahan pengabutan bahan bakar, dengan mempertimbangkan faktor manusia, material, metode, dan mesin secara sistematis dan mendalam. Ditemukan bahwa ketidaksempurnaan pengabutan disebabkan oleh tekanan bahan bakar rendah, penyumbatan nozzle, filter kotor, kualitas bahan bakar buruk, serta purifier yang tidak optimal. Setelah dilakukan perbaikan dan pengujian tekanan, performa Injector kembali normal. Perawatan rutin dan prosedur sesuai manual book menjadi solusi utama untuk mencegah kerusakan serupa. Ketidaksempurnaan pengabutan terjadi akibat tekanan tidak maksimal, penyumbatan nozzle, kualitas bahan bakar rendah, dan filter atau purifier yang tidak terawat. Pencegahan dilakukan melalui perawatan Injector, pengecekan tekanan, penggunaan bahan bakar standar, serta perawatan sistem filtrasi. Perawatan berkala menjamin pembakaran sempurna dan efisiensi mesin yang optimal.   The fuel fogging process in the main ship engine injector greatly determines the combustion efficiency. This process imperfection can be caused by low fuel pressure, nozzle blockage, or poor fuel quality. This research was conducted on the MV. SPIL RUMI to analyze the causes and solutions of such imperfections. This study uses a qualitative approach with direct observation, interviews, and documentation methods during marine practice at MV. SPIL RUMI. The analysis technique uses fishbone diagrams to find the main causes of fuel fogging problems, taking into account human, material, method, and machine factors systematically and deeply. It was found that fogging imperfections were caused by low fuel pressure, nozzle clogging, dirty filters, poor fuel quality, and suboptimal purifiers. After repairs and pressure tests, the Injector's performance returned to normal. Regular maintenance and manual procedures are the main solution to prevent similar damage. Fogging imperfections occur due to suboptimal pressure, nozzle blockage, low fuel quality, and unmaintained filters or purifiers. Prevention is carried out through injector treatment, pressure checking, standard fuel use, and filtration system maintenance. Periodic maintenance guarantees perfect combustion and optimum engine efficiency

Abstract

This study designs and evaluates the feasibility of the TAPTAP digital platform, a Figma-based prototype for measuring port service user satisfaction at the Bontang Harbormaster and Port Authority Office (KSOP Bontang). The study used a Research and Development (R&D) approach adapted into six stages: problem identification, information collection, product design, design validation, design revision, and product trial. Data were gathered through field observation, document review, stakeholder input, and expert feasibility assessment. Two expert testers, consisting of a marine transportation lecturer and an information technology expert, assessed the prototype using a feasibility instrument covering button functionality, initial menu display, completeness and readability of satisfaction questions, presentation of satisfaction results, and overall feature functionality. TAPTAP provides public-side features for satisfaction surveys, complaints, and aspirations, as well as officer-side features for report monitoring and satisfaction-data visualization. The feasibility test produced scores of 80% from Tester 1 and 85.33% from Tester 2, indicating that the prototype is feasible for further pilot testing. The results show that TAPTAP can support more structured service feedback management at KSOP Bontang, although broader public-user testing, database implementation, data security validation, and integration with KSOP systems are still required before operational deployment

Abstract

The electric motor of a ship’s sewage pump operates continuously and plays an important role in the ship’s sanitation system. Therefore, motor condition monitoring is required to prevent operational disruptions. Motor damage is generally preceded by increased vibration caused by imbalance, bearing wear, or improper installation. This study aims to design a real-time monitoring system for electric motor damage of a ship’s sewage pump using a piezoelectric sensor as a vibration detector. The research method used was an experimental method consisting of system design, static testing, dynamic testing, and data analysis. The system was designed using a Moswell MW 125 motor as a representation of the sewage pump motor, a piezoelectric sensor as the vibration detector, an ESP32 microcontroller as the data processor and transmitter, and Node-RED as the monitoring display platform. Dynamic testing was carried out for 30 minutes with data readings taken every 5 minutes. The test results showed that the monitoring system worked according to the design. The motor vibration value under normal conditions ranged from 0.2 to 0.5 mm/s during the testing period, which was categorized as safe and stable. The system was able to display vibration data in a real-time, continuous, and accurate manner through the dashboard. Therefore, the piezoelectric sensor-based monitoring system can be used as an early detection tool for motor damage and to support preventive maintenance of the ship’s sewage pump electric motor.

Abstract

The condition of the ship's generator coolant is always monitored because it affects the performance of the ship's engine. Maintaining the engine coolant temperature is very important to avoid damage that occurs because the engine coolant is too hot on the engine components. With the internet of things, a technological concept has the ability to connect and facilitate the communication process between machines, devices, sensors and humans via the internet network. The aim of this research is none other than to monitor and automatically fill the water level of coolant radiators on generator engines on ships using an IoT system. This research uses a prototyping method system. After designing the tool, testing the tool, monitoring system and automatic filling of the water coolant radiator on the generator engine, the average error rate in the ultrasonic sensor readings when the first test was carried out was 3.02%, the second error was 2.57%, and the third error was 3.63%. Meanwhile, the coolant water discharge data is known to be 3 seconds to 10 seconds with a discharge of 60.7 mL/s. Where this data is monitored on the Blynk 64 mL/s application with an error rate of 5.43%. Therefore, the monitoring and charging system for this water coolant radiator using the IoT system can work well.
