Abstract

This research presents a website-based School Information System at SMP Negeri 4 Kemangkon using the Rapid Application Development (RAD) method. Education, the central pillar of human resource development, requires innovation, especially in applying computerized and internet-connected information systems. Website-based information systems are a solution to facilitate users' access to information, including at SMP Negeri 4 Kemangkon. The formulation of the problem in this study is how to build a website-based school information system at SMP Negeri 4 Kemangkon using the RAD method to facilitate the dissemination of school information and become an effective promotional media. Black Box testing on the functional aspects of this system resulted in 100% validity, signifying the success of system features in meeting requirements and operating without technical problems. The research results in the form of a School Information System of SMP Negeri 4 Kemangkon that can be implemented as an information service and promotional media. This website presents various services, including new student registration (PPDB), extracurricular activities, school vision & mission, teacher data, school contacts, school news, and other information. Overall, this research illustrates the successful development of a school information system with the RAD approach, making a positive contribution in facilitating the dissemination of information and being effective as a school promotion media. Suggestions for future research can be focused on evaluating the system's effectiveness after implementation and developing additional features to improve user experience.

Abstract

The goal of this study is to forecast short-term verified Covid-19 infections in East Java of Indonesia using the NARX-NN model. Here, the external variable used was the weather of East Java. The confirmed data for Covid-19 were obtained from the BNPB, and the weather data of East Java were obtained from the BMKG. Data from July 21st, 2020 to June 20th, 2021, were used for model formation (training data), and data from June 21st to 27th, 2021 were used for validation data. Based on the formatting model results, we can conduct a short-term forecast for three future periods (June 28th to 30th, 2021). This research evaluated the NARX-NN model using the forecasting accuracy of MAPE. The NARX-NN approach is more suitable than the NAR-NN method for predicting daily confirmed Covid-19 cases in East Java, based on the forecasting results of the NAR-NN and NARX-NN methods. The MAPE value was 0.03060 (0.03248 smaller than the MAPE value of the NAR-NN). At the conclusion of the study, the NARX-NN approach was utilized for daily forecasting of Covid-19 instances in East Java from June 28th to June 30th, 2021, namely 1039, 1072, and 1185.

Abstract

One of the factors contributing to the increasing number of banknotes counterfeiting crimes is the technological advancements that have been made in the digital printing industry. Duplications that are very similar and even difficult to distinguish from the original banknote sheet are made easily due to high-quality duplication. Viewing, feeling, and looking carefully at a banknote is the traditional way to check the authenticity of a banknotes. And of course, due to the limitations of human capabilities, such methods are ineffective for many banknotes. Effectively and efficiently, edge detection can be completed by image processing or image processing methods. Using the camera, both real and fake banknotes are transferred. This results in two photos saved as JPG files representing both banknotes. After that, the conversion process to greyscale is carried out, edge observations are made on the image, and then a histogram of both images is created. The results of the histogram were compared and texture was analyzed as judged by the brightness and sharpness of the image. Keywords: Edge Detection, Fake Money, Histogram, Real Money, Texture Analysis.

Abstract

This research aims to identify the readiness of healthcare professionals in regional hospitals to use e-HRD technology. The use of technology in HRM functions is essential to maintain the efficiency and capabilities of human resources within an organization. E-HRD platforms are computerized systems that support the effective and efficient management of HR processes within an organization. To assess the efficiency of employing this technology, it is essential to determine the preparedness of the users. The Technology Readiness Index (TRI) proposed by Parasuraman is applied to assess healthcare workers' preparedness for using e-HRD. The UTAUT (Unified theory of acceptance and use of integrated technology) theory is employed to identify technological readiness. A quantitative descriptive research design is employed to identify the readiness of hospital healthcare workers. The data source for this research is primary data obtained through a questionnaire. The population in this study consists of 420 healthcare workers employed in regional hospitals in the city of Palembang. The sampling technique used in this research is proportional stratified random sampling. Logistic regression is employed to assess the preparedness of healthcare professionals in regional hospitals. The research findings indicate that male healthcare workers have a tendency to be 1.843 times more prepared to use e-HRD compared to female healthcare workers. The likelihood of healthcare workers using e-HRD tends to decrease by 0.002 times with increasing age. The research concludes that healthcare professionals in regional hospitals are moderately prepared to use e-HRD technology. The study recommends that healthcare organizations should provide training and support to enhance healthcare workers' readiness to use e-HRD technology.

Abstract

The rapid development of Electronic Government Systems (EoBS) has brought significant improvements in the efficiency and accessibility of public services. However, the increasing reliance on these systems has also increased concerns about their security and the potential impact of security incidents on government operations and citizen trust. In order to address these challenges, this study proposes a framework for handling security incidents using the ISO/IEC 27035:2023 standard as a reference. The ISO/IEC 27035:2023 standard provides a comprehensive approach to incident management, covering the entire life cycle from preparation and identification to containment, eradication, and recovery. The recommended institution is the Ombudsman of the Republic of Indonesia, a government institution that carries out the function of overseeing the implementation of public services and receiving public complaints regarding alleged maladministration of public services. The preparation of the framework begins with a thorough analysis of the Ombudsman's existing security practices and potential threats to its electronic systems. This assessment is used as a basis for ensuring that the proposed solution is tailored to the specific needs and vulnerabilities of the institution. The stages carried out are preparation, identification, containment, eradication, recovery, and lessons learned. The recommendations produce a framework and insights that government agencies can use to adopt the ISO 27035:2023 standard. This study also shows that the implementation of the standard is relevant and in line with the SPBE policy in Indonesia.
