PENERAPAN LIVENESS DETECTION DENGAN METODE NONLINEAR DIFFUSION DAN CONVOLUTIONAL NEURAL NETWORK

Alvin Christ Ardiansyah — 2025-03-10

With the advancement of increasingly affordable camera technology and the ease of image capture processes, facial recognition has become the biometric authentication method most vulnerable to spoofing attacks. This vulnerability significantly undermines the data integrity and reliability of facial recognition-based attendance systems. Therefore, a liveness detection method is required to help mitigate these spoofing attacks. This study aims to enhance the reliability of existing attendance systems in the teacher and staff attendance application developed for Universitas Mikroskil. In this research, the reliability of the liveness detection system will be tested using a nonlinear diffusion algorithm and Convolutional Neural Network (CNN) against spoofing attacks, employing a confusion matrix method. Based on the conducted tests, the designed liveness detection system achieved an accuracy rate of 87.76%.

KLASIFIKASI FAKTOR PENYEBAB PERCERAIAN MENGGUNAKAN ALGORITMA C4.5

Agnes Irene Silitonga — 2025-03-10

Divorce is a complex social phenomenon that has significant impacts on individuals and society. In Indonesia, divorce is a serious concern for the government and society because the divorce rate has continued to increase in recent decades. Understanding the factors that contribute to divorce is essential to developing effective prevention strategies. The objective of this study is to classify the factors of divorce in Indonesia using the C4.5 algorithm, an algorithm used for data mining in building decision trees. This study used divorce data from 20 provinces in Indonesia in 2023 with various factors causing divorce. Divorce data was obtained from the Central Statistics Agency of Indonesia. The research process includes data collection, data pre-processing, and application of the C4.5 algorithm to build a classification model. The results of the study showed that continuous disputes and quarrels, apostasy, and economy are the most significant factors in divorce. The research results are expected to be a reference for policy makers and marriage counselors in formulating appropriate interventions to reduce divorce rates. The findings of this study can also serve as a foundation for establishing more effective policies and interventions to reduce divorce rates and enhance family institutions in Indonesia.

Untuk menyelesaikan permasalahan tersebut, maka dirancang dan dibangun sistem informasi les privat dengan metodologi waterfall, analisis sistem dengan diagram use case, dan pengujian dengan metode black-box. Hasil dari perancangan dan pengembangan ini adalah sistem informasi berbasis web yang mampu menyelesaikan permasalahan yang masih dilakukan secara manual dalam manajemen kegiatan pembelajaran pada Les Privat Medan dengan lebih efisien dan terstruktur.

SISTEM PENDUKUNG KEPUTUSAN PENERIMAAN BANTUAN DARI PEMERINTAH UNTUK SISWA TIDAK MAMPU DENGAN METODE SIMPLE ADDITIVE WEIGHTING (SAW) PADA SMP PERMATA DEPOK

Muhammad Fiqih Firdani — 2025-03-10

This study aims to develop a Decision Support System (DSS) for the process of receiving government assistance for underprivileged students at SMP Permata Depok. The system is designed using the Simple Additive Weighting (SAW) method to help the school determine aid recipients more objectively and efficiently. The SAW method was chosen for its ability to provide structured assessments based on predetermined criteria, such as parental income, family dependents, and academic achievements. The research process involves collecting data on eligible students, determining the weight for each criterion, and calculating the final score for each potential aid recipient. The result of this system is a prioritized list of aid recipients that can be used by the school as a recommendation in decision-making. The implementation of this DSS is expected to improve transparency and accuracy in the selection process, minimizing subjectivity and potential errors in assessments. Evaluation of the system shows that the SAW method is effective in supporting fair and targeted decisions for students in need of assistance.

IMPLEMENTASI DAN ANALISIS HONEYPOT BERBASIS COWRIE UNTUK MENDETEKSI SERANGAN SIBER

Dhafin Rizky Aulia — 2025-03-10

The use of the internet in Indonesia has grown rapidly. The Indonesian Internet Service Providers Association (APJII) reported that the number of internet users in Indonesia reached 221,563,479 people in 2024, out of the total population. However, as the number of internet users increases, so do the threats that endanger them. Cybersecurity threats continue to evolve alongside the complexity and sophistication of technologies employed by cybercriminals. In addition to building robust security systems, it is equally important to understand the methods used by attackers to design more effective defense strategies. This is where the concept of honeypots comes into play. A honeypot is a security system designed to mimic vulnerable targets, thereby attracting attackers and revealing the tactics, techniques, and procedures they use. One of the most widely used honeypots is Cowrie. This study utilizes Cowrie as an SSH honeypot to be tested against brute force attacks using Hydra. The results show that Hydra successfully identified 15 username and password combinations from the pre-configured Cowrie system.

Affini Salsabilla Isnania — 2025-03-10

Barbershop is a men-only barbershop that has spread in the corners of the city. Barbershop is an option for young people from adolescence to adulthood because barbershop provides more services that cannot be obtained in conventional barbershops. With the high interest of visitors and the need for barbershops, often the search for barbershops becomes an obstacle for visitors because they do not know the location of the barbershop they want, especially to find a barbershop in Baturaja is not easy for visitors from outside the area because of the many barbershops that are in the scope of Baturaja, therefore for the search for barbershopsin Baturaja a Geographic Information System is needed that can make it easier to know the location and distance of barbershops. In designing and building a Geographic Information System, map data is needed in the form of location coordinates by observation at each barbershop. Geographic Information System using Google Maps Application as a map of the region, this system is lighter and easier to use because it only focuses on the location and proximity of barbershop. With the Geographic Information System visitors who come in Baturaja will be helped to find the location of the nearest barbershop.

Samuel Bakkara — 2025-03-13

Fish is one of the most potential animal food products in Indonesia. Over the years, the majority of animal food consumption in Indonesia has been contributed by fish products. The increasing growth rate in North Sumatra is balanced by the food potential that can support the region's food security. Based on data from the fisheries sector potential in North Sumatra, pond fish farming in the province of North Sumatra covers an area of 20,000 hectares, spread across various districts/cities. The pond fish cultivated include catfish, catfish, tilapia, carp, snapper, milkfish, grouper. Given the potential of the pond aquaculture sector and the increasing awareness of the population in North Sumatra to consume fish as a source of nutrition, this research aims to predict pond fish production in North Sumatra. The prediction of pond fish production in North Sumatra is conducted to address the challenges of fluctuating pond fish production, uncertainty in supply and demand using the fuzzy time series method. The results of the study using the Fuzzy Time Series method in forecasting pond fish production in North Sumatra obtained forecast accuracy for catfish of 11.702%, for catfish of 10.359%, for tilapia of 21.636%, for carp of 15.788%, for snapper of 11.487%, for milkfish of 12.87%, for grouper of 12.263%, and for shrimp of 14.814%.).
