Abstract

Harga emas pada saat ini, memang sebaiknya dilakukan dengan menggunakan metode yang mudah di fahami yaitu untuk memepermudah para pembeli maupun penjual dalam melakukan jual beli dan memprediksi turun naiknya harga emas. Untuk menentukan prediksi harga emas menggunakan metode Single moving avarage yaitu metode ini memiliki aplikasi yang sangat luas meskipun sederhanan,karena metode ini hanyalah mengembangkan metode dari rata-rata.sebagian masyarakat yang memiliki. Keberadaan sistem ini semoga dapat membantu masyarakat. Disini penulis memberikan solusi-solusinya untuk mempermudah  para pembisnis dalam melakukan penjualan emas. Dalam penelitian ini peulis jgua memberikan cara memudahkan penjualan emas, agar Penalaran berbasis kasus/single moving avarage merupakan metode yang dipergunakan untuk membangun sebuah sistem berbasis pengetahuan. Sumber pengetahuan sistem diproleh dngan mengumpulkan  data-data penjualan emas. Oleh karena itu banyaknya masalah-masalah  dalam menentukan kisaran harga dan memprediksi harga emas tersebut. Lagkah pertama dalam  menyelesaikan masalah adalah dengan cara mengidentifikasi terlebih dahulu ruang lingkup permasalahan yang akan diselesaikan, hal ini berlaku  juga untuk setiap  pemrograman Artifical Intellegence (AI).

Abstract

Pelatihan dasar akuntansi adalah salah satu bentuk langkah strategis untuk meningkatkan keterampilan manajerial para pelaku Usaha Mikro, Kecil, dan Menengah (UMKM), terutama dalam hal pengelolaan finansial. Kurangnya pemahaman tentang prinsip-prinsip dasar akuntansi menjadi salah satu hambatan utama yang membuat UMKM tidak bisa menyediakan laporan keuangan yang cukup, sehingga menyulitkan mereka dalam mengambil keputusan bisnis maupun mendapatkan akses pembiayaan. Tujuan dari pelatihan ini adalah untuk meningkatkan pengetahuan keuangan para pelaku UMKM melalui pengenalan atas konsep dasar akuntansi, pencatatan transaksi finansial, dan penyusunan laporan sederhana seperti laporan laba rugi dan neraca. Metode pelatihan dilakukan secara interaktif dan aplikatif dengan menggunakan pendekatan studi kasus. Hasil dari evaluasi menunjukkan bahwa pelatihan ini berhasil meningkatkan pemahaman peserta secara signifikan dan mendorong mereka untuk mulai melakukan pencatatan keuangan yang lebih teratur dan sistematis. Dengan demikian, pelatihan dasar akuntansi terbukti efektif dalam memperkuat kapasitas pelaku UMKM menuju usaha yang lebih kompetitif dan berkelanjutan

Abstract

The implementation of online exams differs significantly from exams supervised directly by proctors. Participants' body movements and interactions can be easily read. Even with camera monitoring, participants can still easily switch browser tabs or open applications on their devices. On the other hand, camera-based proctoring solutions can also raise invasive privacy concerns. Furthermore, device limitations can hinder someone from taking the exam due to the lack of a camera, and bandwidth limitations can result in unstable connections during the exam. Sample log activity data from test participants for log_id ranges from 44790 to 46883, while the actions consist of fullscreen_exit, context_switch, standby_log, focus_return, fullscreen_enter, and devtools_open. The results and rules of this test have scores, with each result having an average value of 1, and the rules having an average value of 1-10. In this process, experts assess each detection result using a binary scheme: a score of 1 is given if the expert system's conclusion matches the expert's decision, and a score of 0 is given if the expert system's decision does not match the expert's decision. This study proposes an expert system framework with a cameraless forward chaining method running on the Google Chrome browser (desktop and Android) as decision support. The system utilizes browser event telemetry (visibility changes, fullscreen, standby) that aligns with existing policies, such as mandatory fullscreen mode, copy/paste blocking, and question blurring when exiting fullscreen or a visibility change occurs. This can generate an audit trail that can be audited by decision makers.

Abstract

In the contemporary cybersecurity landscape, the attack paradigm shift from exploiting technical vulnerabilities to manipulating human psychology (social engineering) has reached a critical level. The 2024 and 2025 annual reports from various global and national security authorities indicate that traditional defense mechanisms centered on the technical perimeter are no longer sufficient to stem the tide of attacks targeting the user's cognitive layer. This paper proposes the development and formalization of a new mitigation protocol, TEBAS (Research, Evaluation, Block, Secure, Deliver). This protocol was designed using the Design Science Research (DSR) methodology to address the specific needs of Indonesia's digital ecosystem, characterized by a highly communal culture but facing a significant digital literacy gap. TEBAS integrates human-centric cybersecurity principles with global standard frameworks such as the NIST Cybersecurity Framework 2.0, but is adapted into operational procedures that can be implemented by individuals and communities. Through an in-depth analysis of current attack vectors such as Quishing (QR Code Phishing) and Deepfake Vishing, and validation using a modified Delphi method, this study demonstrates that TEBAS offers a holistic approach that focuses not only on individual detection but also on collective resilience through a community-based intelligence-sharing mechanism ("Convey").
