Abstract

Blockchain merupakan sistem terdesentralisasi yang terbuka yang dapat dimanfaatkan untuk melakukan pelacakan dan verifikasi keaslian dokumen. Sifat keterbukaan tersebut menjadi masalah jika isi dari dokumen bersifat rahasia atau dilindungi oleh undang-undang perlindungan data pribadi. Dalam penelitian ini, sebuah sistem verifikasi dokumen berbasis Blockchain dirancang dengan memanfaatkan algoritma ZKP (Zero Knowledge Proof) yang diimplementasikan dalam sebuah Smart Contract pada jaringan Blockchain Polygon. Algoritma ZKP melindungi informasi yang bersifat rahasia tetapi dapat diverifikasi kebenaran dan keasliannya oleh pihak yang berkepentinga tanpa menguak informasi tersebut. Penelitian ini melibatkan perancangan smart contract yang terdiri dari fungsi-fungsi untuk mengatur proses verifikasi dokumen, serta implementasi sistem verifikasi dokumen yang terintegrasi dengan Smart Contract. Hasil penelitian menunjukkan bahwa sistem yang dibangun dapat meningkatkan keamanan proses pelacakan dokumen dengan tidak menguak isi dokumen yang bersifat rahasia dan dilindungi oleh undang-undang.

Abstract

Previous studies have shown a relationship between secure attachment and marital quality in married couples. However, the correlation between secure attachment and marital quality shows varying results. This meta-analysis aims to evaluate the relationship between secure attachment and marital quality for married couples by revealing how true r is and the effect size of the correlation between the two variables. This meta-analysis research identified 15 studies that he considered eligible, with a total sample of 4.840. The results of the analysis confirm that there is a positive correlation between secure attachment and the quality of marriage in married individuals at a strong level with 95% CI [0,401; 1,053]. The heterogeneity test showed good results, and there was no publication bias.

Abstract

Higher education institutions facechallenges in collaborating with the corporate sector and other academic entities, necessitating secure and effective communication channels. The Merdeka Learning program provides students with an expansive platform to acquire scientific knowledge and ensures equitable competencies among graduates. This study aims to address the increasing importance of data governance in such collaborations by proposing a blockchain-based framework specifically for internship grade conversion. Blockchain technology offers a secure and tamper-proof solution for managing and sharing data, addressing challenges in transparency and consistency. The research adopts an experimental approach combined with a comprehensive review of blockchain technology and its integration into existing data governance frameworks. The proposed outcome includes a detailed data governance framework with a prototype data management layer built on blockchain, ensuring robust data security and reliable internship evaluations. By leveraging blockchain immutability and transparency, the framework enhances the reliability of grade conversion, reduces manual errors, and promotes fair assessments. This research contributes to improving the operational efficiency of academic institutions and fostering trust among stakeholders. Furthermore, the framework aligns with the goals of Merdeka Learning by supporting seamless internship management and ensuring transparent evaluation processes. The findings aim to provide a scalable and impactful solution for higher education institutions, facilitating a more reliable and innovative approach to managing data in collaborative environments.

Abstract

Quick Response Code Indonesian Standard (QRIS) is a QR code standard adopted in Indonesia as an electronic payment method. QRIS allows users to make payment transactions easily using mobile phones. Although QRIS provides many benefits regarding ease and efficiency of transactions, there are some security risks from payment methods using QR codes. A lack of public awareness regarding the safety of using QRIS can open the risk of misuse by irresponsible parties. This study aims to measure the level of security awareness in using QRIS Merchants in the DKI Jakarta areaThe research data was collected using questionnaires based on the Kruger and Kearney models involving 3 (three) dimensions, namely knowledge, attitudes, and behavior, as well as 6 (six) focus areas. The number of samples obtained was 110 respondents. The results showed that the safety awareness of QRIS use in the DKI Jakarta area was 91, in the average value category. With an average score of 91, most respondents realize the importance of paying attention to security aspects in transacting using QRIS.
