Abstract

ALMELLSHOPZ is a shop that carries out buying and selling transactions for clothes, trousers and shoes. The problems that occur in the system that is currently running, namely for managing incoming and outgoing goods data, stock data, goods delivery data, customer data are still recorded in the ledger according to receipts containing how many goods came in and went out to be sent to customers. and stock inventory data is only recorded on a piece of paper and then copied back to the computer by the cashier, so that sometimes there are difficulti es in calculating goods and getting stock information is difficult, sometimes the information provided does not match the availability of existing goods. The aim of this research is to create a stock inventory data system, which can manage incoming and outgoing goods, stock of goods, goods delivery data, customer data using a Java-based sequential search algorithm method at the ALMELLSHOPZ store so that management data management activities are more efficient. One of the advantages of the Java programming language is that it is in great demand by developers and programmers because Java is a programming language that is multi-platform, aka universal and can be used on any platform. This makes many application developers use the Java programming language base to create the desired applications.

Abstract

Malicious URL Detection (MUD) merupakan komponen esensial dalam pertahanan siber, mengingat kerugian finansial global yang disebabkan oleh phishing, penyebaran malware, dan serangan botnet IoT. Pendekatan tradisional seperti blacklisting terbukti tidak efektif melawan URL yang baru dibuat atau polymorphic. Penelitian ini menyajikan analisis komparatif ekstensif dari tiga kelas algoritma utama: Ensemble Learning (Random Forest/RF), Kernel Methods (Support Vector Machine/SVM), dan Deep Learning (DL), dalam mengklasifikasikan URL yang berpotensi berbahaya. Data yang digunakan bersumber dari repositori publik URLhaus, yang sangat fokus pada malware download, khususnya kampanye botnet Mozi dan Mirai. Metodologi studi ini menekankan pada rekayasa fitur multi-modal, yang menggabungkan fitur leksikal, berbasis host/domain, dan fitur berbasis metadata (tag malware). Kinerja model dievaluasi menggunakan metrik yang sensitif terhadap keamanan siber, yaitu Presisi, Recall, dan F1-Score, untuk meminimalisir False Negatives. Hasil analisis memperlihatkan bahwa meskipun model DL mencapai akurasi tertinggi, Random Forest menawarkan keseimbangan optimal antara kinerja deteksi yang kuat dan efisiensi komputasi, menjadikannya ideal untuk implementasi real-time dalam sistem deteksi ancaman. Malicious URL Detection (MUD) is an essential component of cyber defense, given the global financial losses caused by phishing, malware distribution, and IoT botnet attacks. Traditional approaches such as blacklisting have proven ineffective against newly created or polymorphic URLs. This study presents an extensive comparative analysis of three main classes of algorithms: Ensemble Learning (Random Forest/RF), Kernel Methods (Support Vector Machine/SVM), and Deep Learning (DL), in classifying potentially malicious URLs. The data used is sourced from the public repository URLhaus, which focuses heavily on download malware, specifically the Mozi and Mirai botnet campaigns. The study's methodology emphasizes multi-modal feature engineering, combining lexical, host/domain-based, and metadata-based features (malware tags). Model performance is evaluated using cybersecurity-sensitive metrics, namely Precision, Recall, and F1-Score, to minimize False Negatives. The analysis results show that although the DL model achieves the highest accuracy, Random Forest offers an optimal balance between strong detection performance and computational efficiency, making it ideal for real-time implementation in threat detection systems.

Abstract

Login system security is a crucial aspect in digital application development to protect user personal data. This research aims to implement a modern hashing algorithm, Argon2, and add a security layer through Multi-Factor Authentication (MFA) using One-Time Password (OTP) codes. The Argon2 algorithm was chosen because it is memory-hard, configurable, and more resistant to brute-force attacks and rainbow table attacks. The system development method used is the Waterfall method, where the system is developed using the Kotlin programming language with the Jetpack Compose architecture, and the Firebase Authentication and Firestore databases. An OTP is sent to the user after successful registration as additional verification. Implementation results show that the time cost parameter in Argon2id significantly affects hashing execution time, with higher values improving security while remaining within performance tolerances. The combination of Argon2 and MFA successfully provides a more secure login system and is more resilient to cyberattacks than traditional authentication methods. Test results indicate that the Time Cost parameter in Argon2id significantly impacts hashing time. With the following configurations: Time Cost = 1 → 2.028 ms, Time Cost = 2 → 48.623 ms, and Time Cost = 3 → 71.219 ms. Higher parameter values increase execution time but also increase resistance to brute-force attacks. The combination of the Argon2 algorithm and MFA methods results in a more secure and reliable login system than traditional authentication, while remaining responsive in application performance.
