Abstract

This research examines Indonesian P2P lending and bad loan management by analyzing borrower characteristics. The large value of problematic loans is a key signal for this investigation. The Big Five Personality Approach is used to survey P2P lending users. This study solely examines if the Big Five personality traits affect evaluation. On March 5–18, 2023, 17 P2P lending sites gathered data from 197 respondents for two weeks. Data validation continued until 11 respondents were pruned. The remaining 186 respondents' data was evaluated using SPSS. The management process yielded two hypothesis tests, the T-test and the F-test, which showed that the Big Five personality significantly affects present assessment activities. F-Test findings show the Big Five Personalities have a big impact concurrently. These two factors suggest that the Big Five Personalities may evaluate decision support systems for borrower recommendations.

Abstract

In symmetric cryptography, the confidentiality of the chosen key and the security of its delivery mechanism are paramount to minimize the risk of unauthorized disclosure. Typically, in such systems, the sender and recipient focus primarily on the message (plaintext and ciphertext) rather than the complexities associated with key management. This approach aims to alleviate the burden of selecting a suitable and robust key for communicating parties. This study introduces a Hill Cipher modulo 95 cryptography method employing a matrix-based key, where key generation is achieved through a quantifiable randomization algorithm. The developed 2x2 key matrix facilitates a substantial number of possible keys, specifically 954 (exceeding 81 million). The key matrix generation process incorporates several functions, including those for ASCII character conversion, prime number verification, relative primality checks, modulo arithmetic, inverse modulo computation, determinant calculation, and inverse matrix determination. To simulate the encryption and decryption process, a desktop application was developed using the Lazarus Development IDE version 3.6. The application demonstrates effective generation of the required key matrix.

Abstract

Perkembangan startup berbasis teknologi informasi (TI) semakin meningkat dewasa ini. Sebagai penunjang keberhasilan bisnis perusahaan, TI memiliki risiko yang timbul di berbagai keadaan terutama di era pandemi COVID-19. Salah satu alternatif yang dapat dimanfaatkan untuk mengelola dan menjamin usaha yang lebih kondusif dan kredibel yaitu manajemen risiko yang tepat. Hal ini karena manejemen risiko menjadi hal yang penting pada bisnis dalam meningkatkan keuntungan dan mempertahankan kontinuitas bisnis, terutama dalam kondisi pandemi COVID-19. Pembahasan manajemen risiko TI secara umum sudah cukup banyak, namun penelitian manajemen risiko dalam menghadapi masa pandemi perlu dipertimbangkan. Hal ini dikarenakan pada masa pandemi ini, TI menjadi salah satu kunci agar bisnis dapat bertahan dan memenangkan kompetisi. Selain itu, pandemi COVID-19 termasuk dalam kasus luar biasa yang belum pernah terjadi dalam kurun waktu ratusan tahun, sehingga secara teknis risiko dari pandemi ini termasuk dalam risiko yang tidak terpikirkan sebelumnya oleh perusahaan. Tujuan penelitian ini untuk mengidentifikasi kondisi implementasi manajamen dan ancaman risiko terhadap proses bisnis pada sebuah perusahaan startup terutama di masa pandemi. Penelitian ini menggunakan metode kualitatif dengan mengacu pada COBIT® 2019 fokus domain DSS04 Manage Continuity dengan melakukan observasi awal terhadap kondisi perusahaan dan wawancara terhadap pemangku kepentingan perusahaan. Hasil penelitian menunjukkan bahwa perusahaan telah melakukan penyesuaian terhadap kebutuhan bisnis selama masa pandemi COVID-19 untuk memastikan keberlangsungan bisnis. Namun dalam pelaksanaannya belum ada pengukuran risk management untuk mengontrol apakah manajemen risiko yang dijalankan sudah tepat, sehingga diperlukan penerapan COBIT® 2019 dalam tata kelola bisnis perusahaan. AbstractThe development of information technology (IT) based startups is increasing nowadays. To support the company's business success, IT has risks arising from various circumstances, especially in the era of the COVID-19 pandemic. One alternative that can be used to manage and ensure a conducive and credible business is proper risk management. This is because risk management is important for businesses in increasing profits and maintaining business continuity, especially in the conditions of the COVID-19 pandemic. There is a lot of discussion about IT risk management in general, but research on risk management in dealing with the pandemic needs to be considered. This is because during this pandemic, IT is one of the keys for businesses to survive and win the competition. In addition, the COVID-19 pandemic is included in an extraordinary case that has not occurred in hundreds of years, so that technically the risks from this pandemic are included in risks that were not thought of before by the company. The purpose of this study is to identify the conditions of management implementation and risk threats to business processes at a company startup, especially during the pandemic. This study uses a qualitative method with reference to COBIT® 2019 focused on the DSS04 Manage Continuity domain by conducting initial observations of the company's condition and interviews with company stakeholders. The results show that the company has made adjustments to business needs during the COVID-19 pandemic to ensure business continuity. However, in practice there is no risk management measurement to control whether the risk management is carried out properly, so it is necessary to implement COBIT® 2019 in corporate business governance.

Abstract

Health Information System is a systematic way of managing information at all levels of government to provide healthcare services to the community. In providing services to the community, the health information system is a systemic management of information at all levels of government. Every healthcare facility in Indonesia must maintain electronic medical records based on Permenkes No. 24/2022. This shows that the role of Health Information Systems is needed in a health system. However, using electronic medical records (EMR) in Indonesian healthcare facilities must be uniformly and sufficiently implemented, so it cannot provide accurate and timely data. This study aims to assess the implementation of EMR in Indonesian hospitals. This study used the literature review method by reviewing 15 journal articles published between 2016 and 2022, retrieved through Google Scholar. The results showed that several hospitals in Indonesia had implemented EMR; some hospitals have effectively implemented it and benefit from the implementation of EMR, such as improving the efficiency of time and effort in providing health services to patients. Patients also receive better medical care. The study findings aim to encourage all healthcare facilities to optimize the use of EMR to enhance healthcare services.

Abstract

Purpose: To evaluate the governance of the LaporGub Central Java service portal information system using the COBIT 2019 framework to obtain a comprehensive overview of the implemented capability levels. Methods: This study employs a qualitative method using the COBIT 2019 framework to assess capability levels, which is further combined with CMMI to provide improvement recommendations. The method produces valid and accurate results as respondents are selected using the RACI model, and the assessment is conducted at the subdomain level. Consequently, each domain yields valid outcomes, enabling precise and well-targeted recommendations. Results: This study successfully determined the level of LaporGub service capability using COBIT 2019 and showed that most domains have achieved, and in some cases even exceeded, the set targets. However, several areas still require improvement, especially in services security and business process control, as well as problem management. These findings indicate that the Central Java Provincial Communication and Information Office has a strong foundation in operational management and service sustainability. With proper improvements in IT governance, LaporGub is expected to serve as a model for adaptive and accountable digital public services that can be replicated in other regions across Indonesia. Novelty: This study introduces innovation by integrating COBIT 2019 with CMMI, an uncommon combination in capability level assessments within government institutions. Innovative techniques such as text development, respondent questionnaires based on the RACI model, and interviews are used to avoid redundancy in the research findings. By utilizing questionnaires, interviews, and document reviews, this approach enhances the validity of the study results.

Abstract

Purpose: The research aims to determine the factors that encourage users to upgrade service packages, provide actual recommendations for application developers to improve service quality, and provide insights for the development of similar applications in the future. Future Link is an application that offers efficient online fingerprint analysis with the support of artificial intelligence (AI). Despite these advantages, user acceptance and satisfaction remain challenges that hinder service package upgrades. Methods: This study combines the TAM and EUCS models to identify the variables that influence users' intentions to upgrade their service packages in a fingerprint analysis application. TAM includes key constructs such as perceived usefulness and attitude toward using, while EUCS encompasses dimensions like content, accuracy, format, timeliness, and ease of use, which collectively represent users’ satisfaction with the quality of information provided by the application. Additionally, two external variables curiosity and buying intention were added. A quantitative approach was employed using a survey method, with data collected from 151 respondents who are active users of the application. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) through Smart-PLS 3.29. The analysis process included instrument development based on validated indicators, testing for construct reliability and validity, followed by evaluation of the structural model to assess the significance and explanatory power of the hypothesized relationships among variables. Result: The findings show that eight out of nine hypotheses were accepted. Significant variables influencing attitude toward use include curiosity, content, format, accuracy, perceived usefulness, and ease of use. User attitude significantly influences satisfaction, which in turn impacts service package upgrade intentions. Novelty: The combination of two theoretical models the TAM and EUCS model is used to analyze user behavior in the context of service package upgrades in fingerprint analysis applications. While previous studies have applied TAM and EUCS separately to evaluate general technology adoption or information satisfaction, this study integrates both models to provide a more comprehensive framework that considers both perceptual and experiential factors influencing user decisions. Furthermore, this study introduces two additional variables curiosity and purchase intention to reflect emerging user motivations in the use of digital services. The results are expected to support the development and improvement of applications in the future.

Abstract

This research presents the development process of a machine learning neural network model for predicting hemodynamic changes in patients after premedication, aiming to enhance the performance of medical interventions. The model was constructed using 3055 patients’ data who underwent premedication processes. The developed neural network model has an architecture consisting of 10 nodes in the input layer, 10 nodes in the hidden layer, and 3 nodes in the output layer. The evaluation results of the model indicate an overall accuracy of 85%. The precision values are high for normal class predictions at 0.85 and for hypertension class predictions at 0.81 with corresponding recalls of 1 (high) and 0.6 (moderate), respectively. However, predictions for the hypotension class still have a low precision of 0.6 and a recall of 0.04 (very low) due to the significantly lower number of samples in the hypotension class compared to the normal and hypertension classes. While testing with new data, the model has successfully predicted whether patients will experience hemodynamic pressure changes. It is expected that this model can contribute to improving the performance of medical interventions, thereby minimizing undesirable hemodynamic pressure changes.
