Design and Implementation of Anti-Theft Distribution Transformer Monitoring System for Rural Africa
Get PDFThis paper designs a 15KVA three-phase distribution transformer incorporated with a three-phase smart meter for automatic monitoring against theft and vandalism. The monitoring system is designed to send short message services (SMS) to the power utility company when there are abnormalities in the transformer parameters [such as overload, temperature rise, load current, oil level, and voltage variation]. The monitoring unit consist of an embedded system which houses the Arduino Microcontroller, global system for mobile communication (GSM) modem SIM900 for sending SMS, load current sensors which determines the load connected to the transformer, and Bypass current sensors which checks for illegal connection to the transformer. The Arduino Microcontroller/embedded system is connected through a relay to the distribution transformer while the SIM900/GSM module is connected to the Microcontroller/embedded system, relay and optocoupler. The optocoupler isolates the high voltage side of the circuit from the low voltage side. The embedded module process, transmit and receive the parameters to/ from the GSM modem while the GSM module is the link between the embedded system and the public GSM network. The utility provider is expected to have a personal computer (PC)-based -server located at the utility control center basically to collect data from the transformer. This paper presents an alternative method of protecting transformer electrical installations using electronic means compared to the conventional cases of using patrol vehicles by the power utility service provider
Public Transport Passenger Satisfaction in Surabaya Using Ordinal Logistic Regression and Importance Performance Analysis
Get PDFPublic transportation has an important role in everyday life, namely reducing congestion and avoiding traffic accidents. However, in reality, public transportation tends to be abandoned by the people of Surabaya. The tendency of public transportation to be abandoned by the people of Surabaya City is due to reduced public satisfaction with the quality of public transportation services. This study aims to determine the factors that affect the satisfaction of public transport passengers in the city of Surabaya using Ordinal Logistics Regression and identify what service quality needs to be improved and maintained in urban transportation using the Importance Performance Analysis method. The results of this study indicate that 70% of public transport passengers in Surabaya are dissatisfied with the quality of the public transportation service. Variables that affect passenger satisfaction are reliability (the ability of the public transportation to provide the promised service immediately), responsiveness (the ability of the driver to assist passengers and provide responsive and fast service), assurance (the knowledge and ability of the driver to maintain passenger trust), empathy (care driver to passenger needs), direct evidence (passenger attractiveness to the physical facilities of the public transportation), and transportation fares. The service quality variable that becomes the main priority for improvement is the ability of the driver to provide the promised service immediately, the knowledge, ability, courtesy and safety of the driver in carrying out their duties as well as attractiveness to physical facilities

Application of Internet of Things (IoT) and Big Data in the Maritime Industries: Ship Allocation Model
Get PDFThe Internet of Things (IoT) and Big Data (BD) are growing significantly. IoT is defined as a gateway of technology to digital transformation. To work effectively, BD, Artificial intelligence (AI), and blockchain all rely on those data. Once the physical framework information is changed into computerized digital data, an opportunity opens up to improve vessel operations. Research shows that much of the hidden information can help improve vessel operations by leveraging BD and IoT. Therefore, other sectors of the value chain players such as consignees, shipyards, shippers, manufacturers, and classification societies are also interested in maritime BD. In recent years, the world's ship logistics industry has undergone major changes due to the global shipping cargo movement. The availability of numerous BD is also growing exponentially. This will make it possible to utilize many BDs and IoT in the shipping industry. Successful utilization of these BDs and IoT will bring about major innovations in the shipping industry. In this study, we reviewed several applications of BD and IoT in the maritime domain and developed a ship allocation model using maritime BD and IoT-extracted data. As a result, ship allocation establishment is discussed, and the ship allocation result is evaluated
