Abstract

The COBIT framework has evolved into COBIT 2019 and is still the most widely used framework by IT auditors who use complete or customized model components to assess IT governance in an organization or company. COBIT has made it clear that to gain a complete insight into the governance model in an organization, IT auditors must incorporate organizational culture assessment into the audit approach. This study aims to analyze the implementation of the COBIT 2019 framework to improve information technology performance in Tokopedia. This study uses a qualitative descriptive approach where data collection is carried out using primary and secondary data from direct observations of Tokopedia's e-commerce system through tokopedia.com pages and literature reviews from several relevant journal articles. The results showed that the results of the evaluation of the performance of information technology governance in the Tokpedia e-commerce system that focuses on the DSS (Deliver, Support, and Service) domain show that some e-commerce systems still do not fully carry out good information technology delivery, support, and services.

Abstract

This study aimed to analyze the steps contained in the updated model. The model includes six interrelated dimensions of information system (IS) success, namely system quality, information quality, service quality, user satisfaction, and net benefits. The research method used is an explanation with a quantitative approach. The type of research conducted is a survey, where data is collected through filling out questionnaires through Google Form. The data used in the study was collected between January and March 2023. The study sample consisted of 96 respondents who had filled out questionnaires. The results showed that hypothesis 1 was accepted, which showed that the quality of information had a positive effect on customer satisfaction, with a P-Values value of 0.012. However, hypothesis 2 was rejected, which showed that the quality of the system had no effect on customer satisfaction, with a P-Values of 0.185. Furthermore, hypothesis 3 is accepted, indicating that service quality positively affects customer satisfaction, with a P-Values of 0.000. Hypothesis 4 is also accepted, which shows that customer satisfaction positively affects net benefits, with a P-Values of 0.000. Keywords: net benefit, user satisfaction, information quality, service quality, system quality

Abstract

EOT (Engine Order Telegraph) is the embodiment of a machine-human interface that is controlled by the captain of the ship for safe and sustainable ship maneuvers as a basic part of a connected remote propulsion system. Remote control systems on modern ships usually have a control transfer system that allows control to be transferred between locations. Remote control is usually possible from two locations: the platform and the Engine Control Room (ECR). Some ships do not have a remote control handle on the ECR. When in bridge control mode, the bridge handle directly controls the engine set point. When in Engine Control Room mode, the bridge handle sends a telegraph signal to the ECR and the ECR handle controls the control system set point. In local control, the remote control system is inactive and the bridge handle sends a telegraph signal to the local control position and the machine is operated by its manual control in the engine room. In this study, an EOT device will be realized using the Arduino Mega2560 microcontroller and data communication using the RS485 serial from the bridge to the engine control room.

Abstract

The main objective of this research is to improve the operating efficiency and performance of ship main engines by optimizing coolant flow. Improper coolant flow can cause excessive temperature rise in the engine, which in turn can reduce engine life and efficiency. In this research, the coolant flow control system is implemented using the fuzzy logic method. Fuzzy logic allows modeling that is more adaptive to parameter variations and uncertainties in the operational environment. Fuzzy rules are developed based on practical knowledge of experts and operational data related to the host machine. The test was carried out through a simulation using a water flow control circuit that supplies the coolant to the ship's main engine with the main components being an ESP32 microcontroller chip and three DS18B20 temperature sensors. The results of this research show that the use of fuzzy logic in regulating coolant flow is able to provide a faster and more accurate response to changes in engine operational conditions. This has the potential to increase cooling efficiency and prevent engine over-temperatures, which can ultimately increase the overall service life and performance of the host engine. The practical implications of the results of this research can be applied in the development of more intelligent and adaptive control systems for various types of host machines, with the potential to increase operating efficiency and reduce the risk of damage due to excessive temperatures
