Abstract

The development of blockchain technology has brought significant innovation to the Islamic finance industry, particularly in the sharia peer-to-peer (P2P) lending fintech sector. One of the main components of this technology, namely smart contracts, offers opportunities to strengthen sharia principles such as fairness, transparency, and efficiency in financial transactions. This study aims to analyze the implementation of smart contracts in the Islamic P2P fintech ecosystem in Indonesia through literature review and analysis of applicable regulations. The results show that although smart contracts have the potential to support maqāṣid al-sharī‘ah, their successful implementation is highly dependent on regulatory readiness, understanding of fiqh muamalah, and the digital literacy of the Muslim community. Sociologically and culturally, smart contracts also reflect a shift in contract practices from traditional to digital forms, challenging the authority of conventional scholars and opening up space for technological ijtihad in Indonesian Muslim society. This study contributes to the understanding of how Islamic values can be transformed contextually in the face of digital change, as well as offering normative reflections on the integration of technology in contemporary sharia economic practices

Abstract

Abstract: Women with disabilities continue to experience multiple forms of discrimination in public spaces resulting from the intersection of gender and disability. This condition often positions women with disabilities as vulnerable and socially perceived as lacking agency. However, empirical realities show that some women with disabilities actively exercise agency in responding to such discrimination. This study aims to analyze the forms of multiple discrimination experienced by women with disabilities in public spaces and to examine how their agency is constructed and practiced in facing these challenges. This research employs a qualitative descriptive-analytical approach. Data were collected through in-depth interviews with three empowered women with disabilities who are actively engaged in public spaces, supported by limited observation. Data analysis was conducted using thematic analysis based on the Miles and Huberman model. The findings indicate that multiple discrimination manifests in symbolic exclusion, paternalistic treatment, and doubts about women’s capacities. Nevertheless, women with disabilities develop agency through family support, education, social and organizational networks, and professional positions. Their agency is expressed through strategies of capacity demonstration, identity negotiation, critical adaptation, and collective agency strengthening. This study emphasizes that women with disabilities should not be viewed as passive subjects but as active social actors capable of navigating and challenging discrimination in public spaces.   Keywords: Women With Disabilities, Double Discrimination, Agency, Public Space.   Abstrak: Perempuan penyandang disabilitas masih menghadapi diskriminasi ganda di ruang publik yang bersumber dari persilangan identitas gender dan disabilitas. Kondisi ini sering kali menempatkan perempuan difabel pada posisi rentan dan dipersepsikan tidak berdaya. Namun, dalam praktik sosial, sebagian perempuan difabel justru menunjukkan kapasitas agensi yang aktif dalam menghadapi berbagai bentuk diskriminasi tersebut. Penelitian ini bertujuan untuk menganalisis bentuk diskriminasi ganda yang dialami perempuan difabel di ruang publik serta mengkaji bagaimana agensi perempuan difabel berdaya dibangun dan dijalankan dalam menghadapi diskriminasi tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan jenis deskriptif-analitis. Data diperoleh melalui wawancara mendalam dengan tiga perempuan difabel berdaya yang aktif di ruang publik, serta dilengkapi dengan observasi ringan. Analisis data dilakukan menggunakan analisis tematik dengan model Miles dan Huberman. Hasil penelitian menunjukkan bahwa diskriminasi ganda dialami dalam bentuk diskriminasi simbolik, perlakuan paternalistik, dan keraguan terhadap kapasitas perempuan difabel. Meskipun demikian, perempuan difabel membangun agensi melalui dukungan keluarga, pendidikan, jaringan sosial dan organisasi, serta posisi profesional. Agensi tersebut diwujudkan melalui strategi pembuktian kapasitas, negosiasi identitas, adaptasi kritis, dan penguatan agensi kolektif. Penelitian ini menegaskan bahwa perempuan difabel bukan subjek pasif, melainkan aktor sosial yang berdaya dalam menghadapi diskriminasi di ruang publik.   Kata Kunci: Perempuan Difabel, Diskriminasi Ganda, Agensi, Ruang Publik

Abstract: Data security is a crucial and urgent issue to address, especially with the increasing number of cyber threats such as hacking attacks, data theft, and malware that can cause material and non-material losses to individuals and organizations. This study aims to implement the International Data Encryption Algorithm (IDEA) symmetric cryptography algorithm to secure text data in .xls format files that are often used to store important and confidential documents. More specifically, this study was conducted to secure .xls file data using the IDEA algorithm and to design and develop a web-based data security application that utilizes the International Data Encryption Algorithm (IDEA) algorithm. The IDEA algorithm is implemented in a web application built using the PHP programming language, where the encryption process is carried out by converting text data from .xls files into ciphertext that cannot be read by humans or machines without the right key, while the decryption process is carried out to return the data to its original form. The results of the study show that the IDEA algorithm is able to encrypt and decrypt .xls files effectively and efficiently with a relatively fast processing time and a very high level of security against various attacks, including brute force attacks.   Keywords: Data Security, Cryptography, IDEA Algorithm, Symmetric Encryption, Web Application Abstrak: Keamanan data menjadi salah satu isu yang sangat krusial dan mendesak untuk diatasi, terutama dengan semakin meningkatnya berbagai jenis ancaman siber seperti serangan hacking, pencurian data, dan malware yang dapat menyebabkan kerugian material maupun non-material bagi individu maupun organisasi.

Abstract

New student admission is a process in educational institutions that screens prospective students according to established criteria. The new student admission process typically involves registration, file selection, and acceptance. However, the student admission selection process at the South Tapanuli Education Institute is still manual, making it difficult to select one candidate from among the prospective students. This problem gave rise to the idea of ??creating a decision support system to make accurate decisions regarding new student admissions in accordance with institutional policies. The parameters used in this decision support system are the average school exam score, academic potential test, parental income, and parental dependents. This decision support system was developed using a ranking technique using Simple Additive Weighting (SAW), weighting using the Analytical Hierarchy Process (AHP) technique. This method was chosen because it allows for the selection of the best alternative from various alternatives. The use of the Analytical Hierarchy Process (AHP) and Simple Additive Weighting (SAW) methods in determining the passing of prospective new students allows for a more objective, transparent, and effective selection process, which ultimately improves the quality of student admissions and supports better decision-making in student admissions at the Tapanuli Selatan Institute of Education.
