Abstract

Currently, information has become a commodity or basic need, it can even be said that we are already in an "information-based social" era. It is undeniable that the ability to access and ensure the availability of information quickly and accurately has become a very essential component for an organization, whether in the form of social or commercial organizations, educational institutions such as universities, government agencies, and individuals. Various channels were created to regulate access rights to information, to prevent unauthorized people from accessing it, to minimize losses for the owner of the information. Based on the results of interviews with the research object of XX college, there are still frequent disruptions to information system security such as attacks on servers that result in server downtime, attacks on institutional e-mails that result in being unable to receive or even send e-mails, and other disturbances. This certainly harms information services at the tertiary institution, therefore an information system security audit is required. This study aims to measure the level of information system security capabilities using the Cobit 5 framework in the APO13 and DSS05 domains. Based on the results of the audit, it was found that the GAP value was 3.6 for the APO13 domain or at level 1 while 3.4 for the GAP DSS05 value or at level 2, it can be concluded that the information system security maturity level is still very low so that it needs improvement. It is recommended to make SOPs and documentation of maintenance, control, and periodic security evaluation, install an antivirus that has high and up to date protection accuracy, and make regular maintenance reports both on software and hardware.

Abstract

Reliable and up-to-date information services are one of the parameters for the achievement of an organization's performance, including for a university, which is currently required to be able to adapt to technological advances to produce graduates who can master information technology to support the competence of their respective fields. The curriculum changes launched by the current government are also proof that the application of information technology in higher education is a must. Seeing this, universities have a difficult task, especially at the implementation stage of implementing information technology, because they must prepare not only infrastructure but also human resources who can develop good information system governance. Therefore it is necessary to carry out an IT governance audit. From the results of observations made, XYZ College has utilized information technology in academic services and other information services. However, it was found that information technology governance does not yet have a standard so that it is considered not to be able to meet the desired goals, and instead will cause various problems including uncontrolled operational costs and other problems. The purpose of this study is to measure the performance of information technology governance at XYZ College using the COBIT 2019 framework. Based on the results of an audit conducted from 7 EGIT components, namely processes, organizational structure, information flow and items, people skills and competencies, policies and procedures, culture, ethical behavior, and service infrastructure and application are on average at level 3, it can be concluded that the application of information technology has been running, the infrastructure is adequate but does not have good governance procedures or standards. It is recommended that XYZ Higher Education make standards for information technology governance as well as periodic evaluations of the use of all components of information technology, both software, hardware, and brainware.

Abstract

For a company, employees are the spearhead for the company because they have a function as Customer Service, customer satisfaction is obtained after interacting with the company through the performance of its employees. Employees are expected to meet all customer needs with the applicable regulations in the company and become a source of income for the company. To get reliable employees, one way is to assess the suitability of their placement in the appropriate position. With the assessment of the suitability of positioning, companies can consider and determine the provision of rewards, promotions, punishments, training, coaching, counseling, or transfers for their employees. The choice of method used to assess the suitability of employee placement in a company is Fuzzy Mamdani. With the Fuzzy Mamdani method, a system that is completely measurable and human assessments that tend to be immeasurable can be bridged. Assessment of the suitability of employee placement using the resulting fuzzy method, is expected to be an alternative solution for companies to give positions to their employees.

Abstract

Patient segmentation based on perceptions of service quality is a crucial step in improving patient experiences, optimizing resources, and enhancing healthcare service quality. However, understanding patients' needs and priorities in depth poses a challenge, particularly for hospitals serving populations with diverse demographic backgrounds. This study aims to cluster patients in a private hospital in Jambi City based on their perceptions of service quality using the K-Means algorithm. Data were collected from a 2022-2023 survey, covering patient demographics and perceptions of service quality. The data were processed through preprocessing steps, including missing value imputation, normalization, and encoding. The optimal number of clusters was determined using the Elbow and Silhouette Score methods. The results revealed three main clusters with distinct characteristics. The first cluster (34.29%) includes patients prioritizing service speed and procedural ease. The second cluster (46.12%) consists of patients who emphasize staff competence and cost fairness as their main priorities. The third cluster (19.59%) comprises patients with higher educational backgrounds who are more critical of facility quality and complaint handling. Evaluation using the Davies-Bouldin index demonstrated good cluster separation (score -0.645). This study concludes that patient segmentation based on perceptions of service quality can serve as a foundation for strategic decision-making to improve hospital service quality. Recommendations for future research include applying other algorithms such as DBSCAN, integrating sentiment analysis, and employing a hybrid approach to predict patient needs. These approaches are expected to provide a deeper understanding and more effective personalization of patient care.

Abstract

This article discusses the modification of the Caesar Cipher algorithm by adding a key as a way to increase its security. Caesar Cipher is one of the classic algorithms used to encrypt messages by shifting each letter in the original message 3 times, where the shift is 3 times as the key used. However, even though Caesar Cipher is relatively simple and easy to implement, this algorithm is vulnerable to brute force attacks because it only has 26 possible shift ciphers. Therefore, the authors propose a modification by adding a key to this algorithm. In this modification, keys are added to each letter of the original message before it is shifted, thus making the resulting shift patterns more complex and difficult to solve. The test results show that modifying the Caesar Cipher algorithm with the addition of a key can improve message security. However, the author also realizes that although the addition of keys can improve security, this algorithm still has other weaknesses such as being vulnerable to frequency analysis attacks. Therefore, the authors conclude that this modification can only improve Caesar Cipher's security to a certain level and still needs to be combined with other encryption techniques to achieve better security.

Abstract

Improving the quality of maternity services is a strategic priority in the health system. With the development of technology, data mining has become an effective approach to evaluate the quality of big data-based services. This study aims to compare the performance of two data mining tools—RapidMiner and SPSS—in analyzing labor service data to assess the effectiveness, efficiency, and ease of interpretation of the analysis results. A quantitative approach was used as a method with a comparative design of 500 childbirth data from hospitals. Data were analyzed using RapidMiner with Decision Tree and K-Means algorithms, as well as SPSS with logistic regression and correlation tests. The indicators assessed include prediction accuracy, processing time, and ease of use. The results of the analysis showed that RapidMiner achieved a prediction accuracy of 85.4% and was able to cluster with a silhouette coefficient of 0.65. The processing time is about 12 minutes. SPSS shows an accuracy of 81.2% with a faster processing time of 8 minutes. Significant factors found include the mother's age, complications, and type of delivery. RapidMiner excels in predictive analysis and big data processing, while SPSS is more efficient for conventional statistical analysis. A combination of the two is recommended to obtain more comprehensive service evaluation results. The integration of data mining in health information systems needs to be strengthened to support data-based policies in improving the quality of maternity services.
