Abstract

The development of the utilization of electrical energy sourced from the sun is currently experiencing very rapid development. The use of electrical energy sourced from the sun is not only used for industrial generation, currently the transportation industry also utilizes electrical energy sourced from the sun for propulsion and domestic needs. This study discusses the potential of electrical energy that can be generated by solar PV with a capacity of 2x550 Wp which will be implemented on cadet training ships. Solar irradiance is the most important component for the process of generating electrical energy, where later the irradiance value will become electrical energy using solar PV media. The irradiance value is obtained from a web application called solarglobalatlas which already has big data about the irradiation value in various places. This study took irradiation values in the coordinates area -2.953161°, 104.886022° (-02°57'11", 104°53'10") South Sumatra. The data was taken for 12 months to ensure that the data radiation experienced two seasons according to the characteristics of the area. The best irradiance values occur at 11.00 am – 01.00 pm. The results of the discussion show that the annual electrical energy that can be generated by solar PV with a capacity of 2x550 Wp using the monocrystalline PV type is 1,338.2 kWh with the largest electricity production peak occurring in August of 114.4 kWh. Meanwhile, the smallest production of electrical energy occurred in February at 87.2 kWh.

Abstract

Perawatan mesin kapal yang efektif sangat penting untuk memastikan operasi maritim yang aman dan efisien. Metode pemeliharaan tradisional yang didasarkan pada jadwal tetap sering kali tidak memadai karena dapat menyebabkan perawatan berlebihan atau kegagalan tak terduga. Penelitian ini bertujuan untuk mengevaluasi implementasi sistem manajemen pemeliharaan berbasis kondisi (Condition-Based Maintenance/CBM) pada mesin KMP Munic XI guna meningkatkan efisiensi operasional. CBM menggunakan teknologi pemantauan kondisi dan analisis data untuk melakukan perawatan berdasarkan kondisi nyata mesin, bukan interval waktu tetap. Metodologi penelitian ini melibatkan pemilihan mesin kapal yang akan dipantau, pemasangan sensor vibrasi, termografi, dan analisis oli untuk mengumpulkan data kondisi mesin secara real-time. Data yang terkumpul dianalisis menggunakan teknik statistik dan model prediktif untuk menilai kondisi mesin dan memprediksi potensi kegagalan. Implementasi CBM dilakukan dengan memantau kondisi mesin secara kontinu dan melakukan tindakan perawatan saat diperlukan. Hasil penelitian menunjukkan bahwa penerapan CBM pada mesin KMP Munic XI dapat mengurangi downtime hingga 30%, memperpanjang umur mesin hingga 20%, dan mengurangi biaya operasional hingga 25% dibandingkan dengan metode pemeliharaan tradisional. Studi ini juga mengidentifikasi beberapa tantangan dalam penerapan CBM, seperti biaya awal yang tinggi dan kebutuhan pelatihan khusus bagi kru kapal. Kesimpulan penelitian ini menegaskan bahwa CBM merupakan pendekatan yang efektif untuk meningkatkan efisiensi operasional mesin kapal. Dengan memanfaatkan teknologi pemantauan kondisi dan analisis data real-time, CBM dapat mendeteksi tanda-tanda awal kerusakan, sehingga perawatan dapat dilakukan secara tepat waktu. Rekomendasi untuk pengembangan lebih lanjut termasuk peningkatan pelatihan bagi kru kapal dan pengembangan teknologi pemantauan kondisi yang lebih canggih.

Abstract

Increasing interconnectedness of economic and social activities in a region increases the need for an effective and efficient transportation system. The success of regional development is highly dependent on the role of transportation as the various fields such as economy, social, culture, and security. Smooth flow of passengers and goods can improve the regional economy and facilitate regional development. Tanjung Kalian Ferry Port, located in Bangka Belitung Islands Province, is one of the important ports in supporting the mobilization of goods and passengers between the region and South Sumatra Province. However, operation of this port still experiences various problems such as irregular traffic flow and cargo handling due to suboptimal land facilities. This research is expected to provide comprehensive recommendations to improve efficiency and effectiveness of services and optimize control and port operations as to create a safe, secure, organized, and comfortable port area for the community and users.
