Abstract

Bahan bakar adalah faktor penting dalam kelancaran pengoperasian kapal. Bahan bakar MFO (Marine Fuel Oil) banyak digunakan sebagai bahan bakar mesin penggerak utama karena harganya lebih murah dibandingkan dengan bahan bakar minyak lainnya. Pada proses pembakaran, untuk menghasilkan kalor pembakaran yang tinggi sehingga menghasilkan daya guna yang maksimal salah satunya harus mengetahui karakteristik kimia fisika seperti sifat-sifat fisik bahan bakar dan unsur-unsur yang terkandung di dalamnya. Sifat-sifat bahan bakar meliputi berat jenis, kekentalan, kadar belerang, kadar zat arang C, kadar air, titik beku, titik nyala, dan kadar abu. Karakteristik Marine Fuel Oil (MPO) sebagai bahan bakar residu berat sangat menentukan keandalan dan efisiensi mesin induk kapal. Tujuan penelitian ini adalah untuk mengidentifikasi karakteristik sifat kimia fisiaka bahan bakar MFO (Marine Fuel Oil) dan dampaknya terhadap kualitas pembakaran bakar pada mesin penggerak utama. Penelitian dilakukan dengan studi literature dan mengumpulkan data terhadap obyek melalui observasi, wawancara serta menggunakan dokumentasi pengambilan gambar secara langsung di kapal. Hasil penelitian ini menunjukkan dengan mengetahui bagian-bagian penting dari karakteristik bahan bakar maka kualitas bahan bakar dapat diketahui untuk menghasilkan proses pembakaran mesin induk yang sempurna meliputi tahap persiapan pembakaran (atomisasi, penguapan, pencampuran), reaksi pembakaran, emisi gas buang, ketahanan material mesin, sehingga menghasilkan daya guna yang optimal.

Abstract

This study examines the strategic role of lecturer innovativeness in improving academic performance in maritime higher education institutions. The research analyzes the influence of information technology utilization, knowledge management, and job satisfaction on lecturer innovativeness and lecturer performance. The study applies Innovation Theory, Knowledge-Based View Theory, and Job Satisfaction Theory as the theoretical foundation. A quantitative explanatory method was employed using Structural Equation Modeling (SEM). Data were collected from 203 permanent lecturers at maritime higher education institutions under the Ministry of Transportation in Java Island, Indonesia. The findings indicate that information technology utilization, knowledge management, and job satisfaction positively and significantly influence lecturer innovativeness. Lecturer innovativeness also has a significant effect on lecturer performance, particularly in teaching, research, publication, and community service activities. Furthermore, lecturer innovativeness acts as a mediating variable between the antecedent variables and lecturer performance. This study contributes to the higher education management literature by emphasizing lecturer innovativeness as a strategic factor in improving academic performance and institutional competitiveness.
