This study presents the design and implementation of a hybrid propulsion control system for a trimaran vessel using fuzzy logic. The system integrates a Brushless DC (BLDC) motor and an internal combustion engine, controlled by STM32 and ESP32 microcontrollers, with sensors for speed and current monitoring. The fuzzy logic algorithm was developed with two input variables—speed error and delta error—and one output variable for motor control. Experimental testing was conducted on a trimaran prototype in river conditions to evaluate system performance. The results show that, without fuzzy logic, the vessel’s speed fluctuated significantly, deviating from the reference set point. In contrast, with fuzzy logic control, the vessel maintained a more stable speed, achieving an average error of less than 5%. This demonstrates that fuzzy logic can effectively address the non-linear characteristics of hybrid propulsion systems, providing adaptive control that enhances speed stability and energy efficiency.

The maritime transportation sector, especially in archipelagic countries like Indonesia, faces significant challenges in optimising ship speed and fuel efficiency, particularly when using hybrid propulsion systems. This study aims to design a ship speed control system based on fuzzy logic integrated with a hybrid propulsion system (BLDC motor and diesel engine) for a trimaran vessel. The research employed both static and dynamic testing on the system, measuring parameters such as motor RPM, current consumption, voltage, and fuel efficiency across different speed modes (from 4 km/h to 11 km/h). The results showed that the fuzzy logic-based control system notably improved speed stability and fuel efficiency, especially at lower speeds, compared to conventional systems. Additionally, the system effectively adapted to environmental conditions such as waves and currents, optimising power distribution between the BLDC motor and diesel engine. The conclusion emphasises that this fuzzy logic-based control system offers a promising solution to enhance operational efficiency in hybrid propulsion systems for maritime vessels, ensuring reduced fuel consumption and improved environmental sustainability.

This study examines how employee capabilities and technology-mediated channels shape well-being in hierarchical hotel contexts marked by coercive leadership. Drawing on Approach–Avoidance Motivation and Diffusion of Innovation, we theorize a resource-and-channels model in which (a) Exapro-a capability bundle combining professional experience and proactive personality-enhances employee well-being, and (b) electronic diffusion of innovation (e-DOI) strengthens the welfare returns to Exapro by providing safer, auditable pathways for idea sharing when face-to-face voice is risky. We test the model using a three-wave longitudinal design across 26 three- to five-star hotels in Central Java and the Special Region of Yogyakarta (Indonesia) with N = 100 employees concentrated in frontline, rotating-shift roles. Using PLS-SEM (SmartPLS 4), measurement properties met recommended thresholds. Results show that the direct effect of despotic leadership on well-being is not significant (H1 rejected) once resources and channels are modeled. By contrast, despotic leadership positively predicts Exapro (H2 supported), Exapro positively predicts well-being (H3 supported), and e-DOI positively moderates the Exapro → well-being link (H4 supported). The model explains a moderate share of variance in well-being (R² ≈ .52). The findings reframe leader–well-being debates by demonstrating a suppressed/contingent direct effect of despotism and highlighting that what employees can do (Exapro) and how they can safely make it visible (e-DOI) are pivotal for sustaining well-being. Practically, hotels should build experience-based scripts, select/develop for proactivity, and institutionalize digital codification of micro-innovations while strengthening leadership accountability.

Fires on board a ship are an emergency situation that poses a high risk to the safety of the crew, cargo, and the ship itself. Therefore, the readiness and quality of fire extinguishing system maintenance, especially fire hydrants, are crucial aspects in supporting shipping safety. This study aims to analyze the actual condition of fire hydrant maintenance on the MV Habco Carina, identify challenges encountered, and formulate maintenance optimization efforts to ensure the fire extinguishing system functions optimally during emergencies. The study used a qualitative descriptive method through direct observation on board the ship and interviews with the ship's officers and crew. The study was conducted during the researcher's 12-month sea practice on the MV. Habco Carina. The research results show that several fire hydrant components such as hoses, nozzles, valves, and fire pumps are not in optimal condition due to a lack of regular maintenance, minimal technical competence of some crew members, and weak supervision and documentation. This results in low water pressure and suboptimal system function during fire drills. Recommended optimization efforts include improving the quality of scheduled technical maintenance, strengthening the implementation of the PMS, improving crew competence through technical training, and routinely evaluating the effectiveness of the fire hydrant system. With the implementation of more structured and standardized maintenance, the fire hydrant system is expected to support ship preparedness in preventing and handling fires.

The disproportionate growth between the transportation fleet and the infrastructure causes congestion, pollution, inconvenience and poor service. However, the high growth in transportation fleets managed by the private sector more than those managed by the government is not effective, on the other hand the government does not have enough funds to provide adequate public transportation facilities, so the concept of Allocation Cheap Sourcing is needed which is a collaboration between fleets managed by the private sector and the government. The method used in this study is Evidence based policy . The results of the study show that the effectiveness of collaboration can be in the form of partnerships and new forms of organization (NFO).

Penelitian ini bertujuan untuk menganalisis secara komprehensif korelasi fungsional dan pengaruh variabel kecepatan bongkar (discharge rate) terhadap durasi waktu tunggu (waiting time) armada tongkang di Pelabuhan IBT Mekar Putih, yang berperan sebagai simpul vital dalam rantai pasok energi nasional. Dalam ekosistem logistik maritim yang kompleks, inefisiensi operasional pada terminal curah kering (dry bulk terminal) sering kali bermanifestasi sebagai stagnasi antrean di area labuh (anchorage area), yang berdampak langsung pada pembengkakan biaya demurrage dan ketidakpastian jadwal pasokan batubara ke pembangkit listrik. Menggunakan desain penelitian kuantitatif eksplanatori, studi ini menguji hipotesis pengaruh kinerja alat dan manusia terhadap durasi antrean armada. Data empiris dikumpulkan melalui instrumen kuesioner berskala Likert yang didistribusikan kepada 30 responden ahli operasional (termasuk Department Head, Supervisor, Foreman, dan Operator) selama periode Desember 2024 hingga Juni 2025, yang kemudian dianalisis menggunakan teknik regresi linier sederhana dan uji hipotesis. Hasil analisis statistik mengungkapkan nilai Koefisien Determinasi (R2) sebesar 0,763, yang mengindikasikan bahwa 76,3% variabilitas waktu tunggu tongkang dipengaruhi secara signifikan dan dominan oleh stabilitas kecepatan bongkar. Persamaan regresi yang dihasilkan, Y = 11,801 + 0,717X, mengonfirmasi secara matematis bahwa setiap peningkatan unit performa bongkar akan secara nyata mereduksi durasi waktu tunggu armada. Temuan ini memberikan implikasi bahwa stagnasi di area labuh dapat diminimalisir secara efektif melalui strategi pemeliharaan preventif alat bongkar, peningkatan kompetensi ritme kerja operator, dan digitalisasi sistem penjadwalan sandar guna mencapai efisiensi operasional pelabuhan yang berkelanjutan.
