Section: Articles Keywords: Parking, Internet of Things (IoT), Prototype, ADDIE, Black Box Testing, Arduino R3 The rapid development of technology makes us continue to innovate, especially in the field of technology. Internet of Things (IoT) is an example of technological advancement with the aim of simplifying human performance that can be applied, one of which is in the parking system area. In general, the parking system in Indonesia is still controlled manually by going around all parking locations to get empty parking lots. One of the problems in the parking system in malls in Indonesia is that there is no system used to detect the availability of the number of empty parking spaces and the location of empty parking spaces in the basement. In certain situations such as during rainy weather or on weekends, parking attendants have difficulty managing parking lots because there are too many incoming vehicles making it difficult for parking attendants or motorists to find empty parking spaces. These problems can be resolved by providing solutions utilizing the Arduino R3 microcontroller by making a prototype parking information system sensor using LCD and parking location using LED as a research. This development research uses the ADDIE method as a structured framework stage for the development of instructional interventions that involve evaluation and revision at each step. Testing is done using the Black Box Testing method through simulation with a miniature parking lot, where the system automatically receives from the ultrasonic sensor. The results of making this prototype, obtained a percentage of the success of testing the monitoring system 100% in other words, researchers have succeeded in making a parking lot monitoring system that is more effective and efficient.

Analysis of Fluctuations in Consumption and Power Input of Transjakarta Electric Bus Battery Flow
Section: Articles Keywords: electric bus , State of Charge , Transjakarta , battery charging , energy efficiency The increasing use of electric vehicles as a sustainable transportation solution also encourages their integration into public transportation systems, such as those implemented by PT Transportasi Jakarta. One important aspect of electric bus operations is the efficiency of power consumption and the effectiveness of battery charging. This study aims to analyze the percentage decline in State of Charge (SoC), energy efficiency (kWh/km), and battery charging characteristics of the Zhongtong Medium Low Entry electric bus operating on Transjakarta routes under two operational conditions: without passengers and with passengers. The method used involved direct observation and field data recording over four testing periods, covering energy consumption, distance traveled, and charging capacity, with tests conducted under both operational conditions. The results show that the presence of passengers causes an average SoC decrease of 17% compared to the condition without passengers, and an increase in energy consumption of 43%, from 0.27 kWh/km to 0.70 kWh/km. The incoming electrical power during charging exhibited greater variation under the passenger-loaded condition; however, the average difference was only about 2%, indicating a relatively small impact on the battery charging process. These findings confirm that the additional passenger load significantly affects energy consumption efficiency and SoC levels of electric vehicles but has minimal influence on charging power. This study provides important contributions to energy management and the development of battery charging infrastructure for electric buses to support more efficient and sustainable operations.

Haddon Matrix Approach for Road Safety Intervention in Pacitan Crash-Prone Areas
Section: Articles Keywords: Haddon Matrix, Traffic accidents, Road safety, Interventions Traffic accidents remain a major global concern due to their contribution to high rates of injuries, fatalities, and economic losses. Pacitan Regency, characterized by its winding and hilly roads, experiences a particularly high frequency of accidents, especially in designated accident-prone areas. This study aims to analyze the contributing factors of traffic accidents in Pacitan using the Haddon Matrix approach, which examines human, vehicle, and environmental factors across three phases: pre-crash, crash, and post-crash. The findings reveal that driver misconduct, such as traffic violations and the neglect of safety measures, is the leading cause. Poor vehicle maintenance and inadequate road infrastructure also significantly increase accident risks. The Haddon Matrix proves effective in identifying targeted interventions at each phase, highlighting the need for infrastructure improvements, stricter law enforcement, and enhanced traffic safety education. Recommendations based on the 3E principles—Engineering, Enforcement, and Education—are proposed to offer a comprehensive strategy for reducing accidents and improving road safety. Strong collaboration between government agencies, local communities, and relevant stakeholders is essential to build a sustainable road safety system in Pacitan Regency.

The Impact of Implementing a Safety Management System on Reducing the Ratio of Public Transportation Operational Accidents
Section: Articles Keywords: Implementation, Public Transport Company, Safety Management System, Ratio, Accident This study aims to evaluate the level of implementation, identify obstacles, and formulate recommendations for improving the Safety Management System at PT Anugerah Karya Utami Gemilang in Yogyakarta. The research method uses a mixed method approach with a concurrent embedded strategy. Data collection was carried out through questionnaires, interviews, and observations of 30 respondents from various work units. The results show that of the ten SMK elements studied, seven of them have been implemented very well with an average percentage of 94%, while three elements still need improvement, namely increasing competence & training (75%), monitoring & evaluation (92%), and performance measurement (83%). The implementation of the SMK has contributed to a decrease in the accident ratio by 29.47%. The main obstacles identified were the absence of comprehensive procedural guidelines for these elements, as well as a lack of continuous training programs and a thorough understanding of the importance of evaluation. Improvement strategies include the preparation of detailed Standard Operating Procedures (SOPs), increasing continuous internal training, and developing an integrated and periodic evaluation system to optimize the overall implementation of the SMK and ensure a sustained reduction in accident risk.

Innovative Efforts to Improve Traffic Safety through Singing Road Technology on the Waru–Juanda Toll Road
Section: Articles Keywords: Singing Road, traffic safety, toll road, accident-prone area Traffic accidents on toll roads are a significant issue that requires innovative solutions to enhance driving safety. This study aims to design the implementation of Singing Road technology, also known as auditory rumble strips, at a high-risk accident zone located at KM 03+850 on the Waru–Juanda Toll Road. The research method includes data collection through field observations, interviews with operational officers, and secondary data analysis of traffic accident reports. A hazard level analysis was conducted, followed by a technical design of the Singing Road tailored to the geometric conditions of the site. The design results show that auditory rumble strips can be effectively applied at the specified location to provide auditory stimuli that improve driver awareness. The technical planning was developed based on traffic volume data, vehicle characteristics, and pavement standards, and it was supported by effectiveness calculations using a predictive accident model. This technology is expected to serve as a preventive alternative to reduce the risk of accidents on toll roads.
