Abstract

The application of risk management aims to minimize the probability and or consequences of unfavorable events as well as increase awareness of risk in strategic and operational decision making in an effort to achieve organizational goals. The Internal Audit Unit (SPI) Politeknik Pelayaran Surabaya is a supervisory unit formed to assist the implementation of Good University Governance by carrying out inspections or audits of all work units in the non-academic field.Risk treatment is required through risk management as the implementation of the management function in risk management at SPI Politeknik Pelayaran Surabaya. The risk management process uses a standard risk management process 31000 which consists of a context setting process, risk identification, risk analysis, risk evaluation, risk management, monitoring and review, and communication and consultation. This study uses a descriptive qualitative method with a case study at Internal Audit Unit (SPI) Politeknik Pelayaran Surabaya which describes and analyzes risk management using interview and documentation techniques in data collection. Data were analyzed using an interactive model, including data collection, data reduction, data presentation, and conclusions or verification. The final result of the risk management analysis of the internal audit unit (SPI) Politeknik Pelayaran Surabaya is a form of handling strategy in the implementation of internal control.

Abstract

Risk management aims to minimize the probability and or consequences of unfavorable events and increase risk awareness in strategic and operational decision-making to achieve organizational goals. The Internal Audit Unit (SPI) Politeknik Pelayaran Surabaya is a supervisory unit formed to assist the implementation of Good University Governance by conducting inspections or audits of all work units in the non-academic field.  Risk treatment is required through risk management to implement the management function in risk management at SPI Politeknik Pelayaran Surabaya. The risk management process uses a standard risk management process 31000, consisting of a context setting process, risk identification, risk analysis, risk evaluation, risk management, monitoring and review, and communication and consultation. This study uses a descriptive qualitative method with a case study at the Internal Audit Unit (SPI) Politeknik Pelayaran Surabaya, which describes and analyzes risk management using interview and documentation techniques in data collection. Data were analyzed using an interactive model, including data collection, reduction, presentation, and conclusions or verification. The final result of the risk management analysis of the internal audit unit (SPI) Politeknik Pelayaran Surabaya is a form of handling strategy in implementing internal control.

Abstract

The increasing demand for electrical energy and the limited availability of fossil fuels have driven the development of renewable energy sources, including marine current energy, which remains underutilized in coastal and remote maritime regions. This study presents the design and realization of a small-scale marine current power generation prototype using a horizontal axis propeller turbine with a NACA S814 blade profile and analyzes the effect of turbine rotational speed on electrical power output. The system converts marine current kinetic energy into mechanical energy through turbine rotation and subsequently into DC electrical energy using a generator, which is stabilized by a Buck–Boost Converter and Maximum Power Point Tracking (MPPT) for charging a 12 VDC battery. Real-time monitoring of electrical and mechanical parameters is implemented using an Internet of Things (IoT)–based system comprising an ESP32 microcontroller, a PZEM-017 sensor, and an RPM sensor. Experimental results demonstrate a positive correlation between water flow rate, turbine rotational speed, and generator output voltage. The system begins operating at a minimum flow rate of 35.2 L/s at 56 RPM, producing 0.2 V, while optimal performance is achieved at 45.3 L/s and 516 RPM, generating up to 13.3 V. These results indicate that the proposed prototype is a viable alternative renewable energy source for marine applications.
