Abstract

To ensure a comprehensive and scientifically rigorous analysis, adhering to standardized procedures serves as the foundation of any investigation. In the realm of digital forensics, the establishment of well-defined protocols for generating exhaustive reports to analyze digital evidence holds paramount importance. These reports not only carry significance in legal contexts but are also increasingly valuable across various industries for internal purposes. Esteemed organizations like the International Organization for Standardization (ISO) and the National Institute of Standards and Technology (NIST) have played a pivotal role in shaping recognized standards in this domain. The primary goal of this report is to conduct an in-depth comparison between two prominent digital forensics standards: ISO/IEC 27037, widely embraced in industries, and NIST SP 800-86, predominantly prevalent in academic circles. Through this comprehensive analysis, the report aims to provide valuable insights to Digital Evidence First Responders (DEFR), including law enforcement, academia, and industry professionals. By elucidating the discrepancies, scopes, and limitations inherent in each standard, DEFRs can bolster their understanding, thus empowering them to make well-informed decisions during digital investigations. Future works in this field should focus on the continual evolution of digital forensic practices, adapting to new technologies and challenges, and ensuring that standards remain up to date with the dynamic digital landscape.

Abstract

The use of e-absence for government servants is currently an innovative way to improve the efficiency of work activities in local government. The focus on how the system is implemented and used by government servants is also important to discuss. The research aims to explore how government servants intend to use the e-absence application provided by the Dumai city government. The unified theory of acceptance and use of technology (UTAUT) model is used for examining research problems in which the model has been modified to include a new variable, attitude. This study used a quantitative approach and quota sampling technique that included 100 respondents, all of whom were government servants working for different Dumai government agencies. Questionnaires were distributed using Google forms, with questions adapted from previous research. The study showed that performance expectancy, social influence, and attitude are all significantly and positively connected to intention to use e-absence dan effort expectation and social impact are not significantly and negatively to the intention to use e-absence. Several recommendations for theoretical advancement and the development of the e-attendance system itself have been provided.

Abstract

Sistem Pendukung Keputusan (SPK) merupakan sistem yang dapat memberikan pemecahan masalah, melakukan komunikasi untuk pemecahan masalah tertentu dengan terstruktur maupun tidak terstruktur. SPK didesain untuk dapat digunakan dan dioperasikan dengan mudah oleh orang yang hanya memiliki kemampuan dasar pengoperasian komputer. Pada sekolah untuk menentukan siswa dan mendapatkan siswa berprestasi yang sesuai dengan kriteria sangatlah penting. Sekolah MI-AL IKHLAS sendiri belum memiliki digitalisasi pada bagian administrasinya seperti pendaftaran, absen, penilaian dan juga mengkategorikan siswa berprestasi, tentu saja hal tersebut dapat menghambat pertumbuhan sekolah dalam era digitalisasi saat ini yang dimana sekolah lain sudah melakukan digitalisasi pada bagian administrasinya. Oleh karena masalah tersebut, peneliti bermaksud membangun sebuah aplikasi yang menggunakan metode Simple Additive Weighting (SAW) dalam membantu guru dalam memberikan pertimbangan dan penilaian dalam membuat keputusan. Yang mana berfungsi untuk mengurutkan siswa berprestasi secara otomatis untuk membantu kinerja guru dalam membuat ranking siswa

Abstract

Penelitian ini membahas konsep dan penerapan zakat pada beberapa kategori harta, yaitu gaji, penghasilan, emas, perak, maskawin, dan hewan ternak. Zakat merupakan salah satu rukun Islam yang wajib dilaksanakan oleh setiap Muslim yang memenuhi syarat tertentu. Fokus utama dari kajian ini adalah bagaimana syariat Islam menetapkan nisab dan kadar zakat untuk masing-masing kategori harta tersebut serta bagaimana pelaksanaannya dalam konteks modern. Melalui metode kualitatif dengan pendekatan deskriptif-analitis, penelitian ini menganalisis sumber-sumber hukum Islam, termasuk Al-Qur'an, Hadis, dan pendapat para ulama. Hasil penelitian menunjukkan bahwa setiap kategori harta memiliki kriteria dan metode perhitungan zakat yang berbeda, yang ditentukan oleh nilai ekonomis dan potensi keberlanjutannya. Misalnya, zakat gaji dan penghasilan dihitung berdasarkan jumlah akumulasi tahunan, sementara zakat emas, perak, dan maskawin berdasarkan berat dan nilai pasar. Adapun zakat hewan ternak dihitung berdasarkan jumlah dan jenis ternak yang dimiliki. Penelitian ini juga menemukan adanya tantangan dalam penerapan zakat di era modern, seperti kurangnya pemahaman masyarakat dan keterbatasan lembaga zakat dalam mendistribusikan zakat secara efektif.
