One of the factors less successful learning process in the classroom is that lecturers are less innovative in applying learning methods. Lecturers still use the classical method of discussion. For that, a learning innovation is needed by applying problem solving methods. The study used quasi experimental design. The research population is medan aviation polytechnic cadets amounting to 40 cadets consisting of 20 people control group and 20 people experimental group. The data collection techniques used include interviews, observations, questionnaires, and tests. The statistical analysis used is Pearson ProductMoment to test validity, Cronbach'sAlpha to test reliability, Lilliefors to test normality,Levene's to test homogeneity, and t test and to test differences and effectiveness. Based on the results of the difference hypothesis test using independent samples t test,critical thinking ability data shows the value of tcalculated>ttable (3,740 > 1,998) with a level of significance (0.000 < 0.05) and the value of cadet learning results shows the value of tcount>ttable (3,656 > 1.998) with a significance level of less than 0.05 (0.001 < 0.05). Meanwhile, the results of the effectiveness hypothesis test using one sample t test,critical thinking ability data showeda table >ttvalue (5,724 > 2.037) with a significance level of < 0.05 (0.000 < 0.05) and a cadet learning value showing a>ttable t value (6,009 > 2,037) with a significance level (0.000 < 0.05). So, it can be concluded that there is a difference in critical thinking skills and learning outcomes between those who use problem solving methods and those who use discussion methods. Problem solving methods are effective in improving critical thinking skills and learning outcomes.

Abstract This study discusses the implementation of the Hazard Identification, Risk Assessment, and Mitigation (HIRM) system at the Electrical Workshop Laboratory of Politeknik Penerbangan Medan as part of efforts to create a safe practice environment and foster a culture of occupational safety from an early stage. The laboratory serves as a facility for students to perform practical electrical engineering activities such as soldering, panel assembly, electrical measurements, and handling heavy equipment—activities with inherently high safety risks. The research applies the HIRM approach through stages of hazard identification, risk assessment using a probability and severity matrix based on ICAO Doc 9859 standards, and the formulation of mitigation strategies. Results identified seven main activities with moderate to high-risk levels. The highest risks were found in electrical installation assembly, battery testing, and distribution panel work, which can cause electric shock or serious injuries. Recommended mitigation includes the use of personal protective equipment (PPE), regular safety training, strict implementation of standard operating procedures (SOPs), and increased instructor supervision. The study concludes that HIRM is effective for implementation in vocational education settings, particularly in electrical engineering fields, and recommends the future development of digital monitoring systems for real-time risk assessment and improved laboratory safety management..

Street lighting plays a vital role in ensuring safety and comfort for road users at night. However, the lighting system in Poltekbang Medan Housing Complex is still operated manually without remote monitoring, leading to potential energy waste and inefficiency. This study aims to design an Internet of Things (IoT)-based street lighting monitoring and control system that enables real-time supervision via smartphone. The research method includes literature review, hardware and software design, and system testing. The main components are the ESP32 microcontroller, PZEM-004T sensor for electrical parameter measurement, and relay module for lamp control, integrated with the Blynk application through Wi-Fi connection. Test results show that the system can accurately display electrical data and respond well to control commands, with measurement deviations remaining within acceptable tolerance. The measured lighting intensity of 84 lux closely matches the calculated value of 85.2 lux and complies with the Indonesian National Standard (SNI) for secondary local roads. Therefore, the system is considered feasible as it enhances energy efficiency, accelerates fault handling, and improves safety and comfort through real-time remote monitoring and control.

This research aims to design a VFR Corridor that can connect airports located in the province of North Sumatra, especially those airports that do not yet have a VFR Corridor. The research method used is Research and Development (R&D). Data was collected using observation, literature study, interviews, and documentation. The results showed that the current condition of the VFR Corridor has not connected the eight airports in the North Sumatra region. However, the eight airports can be connected with the new VFR Corridor design consisting of three segments. This design allows VFR aircraft to follow the VFR Corridor path rather than flying direct. In addition, the VFR Corridor design also ensures that the movement of VFR aircraft will not interfere with IFR aircraft following STAR at Kualanamu Airport in Medan and Sisingamangaraja Airport. This study has implications for improving the safety and efficiency of flight operations in the North Sumatra region. With a structured and connected VFR Corridor, VFR aircraft pilots have clearer guidance in air navigation, so the risk of collisions with IFR aircraft can be minimized. In addition, this design also supports the development of aviation infrastructure in North Sumatra, especially in facilitating connectivity between airports that do not yet have a VFR Corridor.
