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.

The development of a student's personality, particularly during classroom interaction, is heavily influenced by their level of self-confidence. A lack of self-assurance often leads to public speaking anxiety, which subsequently restricts student engagement and diminishes academic performance. This phenomenon is frequently identified among tenth-grade Vocational High School (SMK) students who are navigating a period of environmental transition. This research focuses on enhancing the self-confidence of Grade X SMK students struggling with speech-related anxiety through the implementation of group guidance services utilizing role-playing methods. The study follows a Guidance and Counseling Action Research (GCAR) design conducted over two cycles, consisting of preparatory, executive, monitoring, and evaluative phases. The participants were tenth-grade students with low self-confidence profiles as determined by questionnaires and field observations. Data were analyzed using a descriptive quantitative approach to compare performance levels before and after the intervention. The results demonstrate that group guidance integrated with role-playing is an effective strategy for optimizing student self-confidence, as shown by the consistent upward trend in scores throughout the cycles. These findings suggest that this technique serves as a strategic instrument for school counselors to mitigate social anxiety among students.

Trigeminal neuralgia (TN), sometimes referred to as tic doloureaux or Fothergill disease, is a facial nerve disorder that is widely recognized as one of the most excruciating human ailments. It is characterized by sudden, severe, and recurrent episodes of facial pain that can significantly impair a patient’s quality of life. Oral medications are commonly used as first-line therapy; however, they fail to provide long-term relief in approximately half of patients with trigeminal neuralgia. This condition often leads to repeated clinical visits and the need for alternative therapeutic approaches. A 26-year-old woman presented with complaints of severe, intermittent, and sharp pain localized to her left cheek, consistent with the clinical features of trigeminal neuralgia. Several minimally invasive and surgical treatment options are available for managing this condition, including radiofrequency procedures and microvascular decompression. However, these approaches still carry certain risks and may not be acceptable to all patients. Due to its lower risk profile, ultrasound-guided peripheral nerve block can serve as an effective and safer alternative treatment, particularly for patients who refuse or are not suitable candidates for invasive or surgical interventions.
