Abstract

The advancement of technology in the field of image recognition has significantly facilitated and improved the effectiveness of object detection in computer-based banknote recognition systems. This study aims to automatically identify banknotes based on their denominations, with the objective of minimizing human errors—such as lack of concentration, fatigue, and other factors—and enabling its application in ATMs and automated payment systems. This research compares the accuracy levels and detection success rates between the YOLO and SSD algorithms in recognizing the denominations of banknotes. The YOLO model operates by dividing the image into grids and predicting bounding boxes along with object classes in a single step, resulting in fast and consistent detection. In contrast, the SSD model employs a multi-scale approach by utilizing feature maps from multiple levels to generate predictions. The parameters used in this study include 7 classes of Indonesian banknotes: Rp1,000, Rp2,000, Rp5,000, Rp10,000, Rp20,000, Rp50,000, and Rp100,000. A total of 353 images were used in the dataset, and three images from each class were selected for testing purposes. The results of the study indicate a significant performance difference. The YOLO algorithm achieved a 100% accuracy rate under both normal and low-light conditions, while the SSD algorithm achieved an accuracy rate of 87.2% under normal lighting and 91.4% under low-light conditions.

Abstract

Double Exponential Smoothing (DES) is a forecasting method that combines two components level and trend, used for data with a trend pattern that tends to increase or decrease over time. In contrast, Triple Exponential Smoothing (TES) incorporates three components: level, trend, and seasonality, making it suitable for data with trend and seasonal patterns. This study uses historical chili price data from 2020 to 2023, obtained from the Bank Indonesia website, managed by the National Strategic Food Price Information Center (PIHPS), to compare the effectiveness of DES and TES in predicting chili prices in Medan City. Prediction accuracy was evaluated using MAPE (Mean Absolute Percentage Error) and MAE (Mean Absolute Error). The study results show MAPE values for DES as follows: Large Red Chili 1.25%, Curly Red Chili 1.39%, Green Bird’s Eye Chili 1.14%, and Red Bird’s Eye Chili 1.13%. TES produced slightly lower MAPE values: Large Red Chili 1.25%, Curly Red Chili 1.38%, Green Bird’s Eye Chili 1.12%, and Red Bird’s Eye Chili 1.10%. The MAE values for DES are as follows: Large Red Chili 447.9, Curly Red Chili 494.83, Green Bird’s Eye Chili 430.92, and Red Bird’s Eye Chili 423.36. TES showed better accuracy with MAE values of Large Red Chili at 447, Curly Red Chili at 493.02, Green Bird’s Eye Chili at 416.2, and Red Bird’s Eye Chili at 409.36. The results conclude that Triple Exponential Smoothing performs better than Double Exponential Smoothing in predicting chili prices.

Abstract

Abstrak– perceraian adalah pengakhiran suatu perkawinan karena sesuatu sebab dengan keputusan hakim atas tuntutan dari salah satu pihak atau kedua belah pihak dalam perkawinan. Islam sendiri telah memberikan penjelasan dan definisi bahwa perceraian menurut ahli fikih disebut talak atau furqoh. Untuk saat ini angka kasus perceraian di Kabupaten Aceh Tengah mengalami peningkatan yang sangat signifikan pada tahun 2019 sampai dengan pertengahan tahun 2022, bahkan dari 23 Kabupaten di Provinsi Aceh yaitu Kabupaten Aceh Tengah adalah kasus perceraian tertinggi hingga mencapai 1273 kasus pada pertengahan 2022. Dari 1273 jumlah kasus tersebut perlu adanya penerapan algoritma kombinasi atau yang di sebut dengan Hybrid Data Mining menggunakan metode K-Means Clustering dan Decision Tree di mana metode ini berfungsi untuk mengolah data kasus perceraian sebagai tujuan mengklasifikasikan data kasus perceraian di kabupaten Aceh Tengah. Pengujian klaster di lakukan dengan 3 model klaster yaitu k=2,k=3 dan k4. Untuk mendapatkan data dari hasil klaster maka di lakukan pengujian kinerja davies bouldin maka menghasilkan nilai kinerja klaster dengan k=2 adalah -2,127, untuk nilai davies bouldin kinerja klaster dengan k=3 adalah -1,794, sedangkan nilai davies bouldin kinerja klaster dengan k=3 adalah -1,854. Berdasarkan simpulan diatas maka pada model 2 dengan jumlah k=3 dapat ditentukan klaster yang akan direduksi yaitu klaster dengan keanggotaan terkecil yaitu cluster 2 dengan jumlah data yang direduksi yaitu 59 data, sehingga jumlah dataset hasil reduksi yaitu 1.214 data. Dengan data hasil reduksi maka di uji menggunakan algoritma decision tree dengan komposisi split data 90:10’80:20 dan 70:10. Dengan demikian maka menghasilkan nilai akurasi data sebelum di reduksi dengan data setelah di reduksi dengan demikian nilai rata-rata akurasi untuk klasisfikasi tanpa reduksi adalah 85,96%, presisi 84,71% dan recall 79,36% dan untuk akurasi setelah direduksi adalah 87,90%, presisi 87,22%, dan recall 82,72%. Sehingga dapat disimpulkan bahwa akurasi klasifikasi dataset setelah direduksi lebih tinggi dari akurasi klasifikasi tanpa reduksi.

Abstract– Divorce is the termination of a marriage for any reason by a judge's decision based on the demands of one or both parties in the marriage. Islam itself has provided an explanation and definition that according to fiqh experts, divorce is called talak or furqoh. Currently, the number of divorce cases in Central Aceh Regency has increased very significantly from 2019 to mid-2022, In fact, of the 23 districts in Aceh Province, Central Aceh District has the highest number of divorce cases, reaching 1273 cases in mid-2022. Of the 1273 cases, it is necessary to apply a combination algorithm or what is called Hybrid Data Mining using the K-Means Clustering and Decision Tree method, where this method functions to process divorce case data for the purpose of classifying divorce case data in Central Aceh district. Cluster testing was carried out with 3 cluster models, namely k=2, k=3 and k4, To get data from the cluster results, the Davies Bouldin performance test was carried out, resulting in a cluster performance value with k=2 which was -2.127, for the Davies Bouldin value of cluster performance with k=3 is -1.794, while the Davies Bouldin value of cluster performance with k=3 is -1.854. Based on the conclusions above, in model 2 with the number k=3, the cluster that will be reduced can be determined, namely the cluster with the smallest membership, namely cluster 2 with the amount of data reduced, namely 59 data, so that the total dataset resulting from the reduction is 1,214 data. With the reduced data, it was tested using a decision tree algorithm with a data split composition of 90:10'80:20 and 70:10. In this way, the accuracy value of the data before reduction is produced with the data after reduction, so the average value of accuracy for classification without reduction is 85.96%, precision is 84.71% and recall is 79.36% and for accuracy after reduction is 87. .90%, precision 87.22%, and recall 82.72%. So it can be concluded that the classification accuracy of the dataset after reduction is higher than the classification accuracy without reduction. Keywords: divorce data, hybrid, k-means clustering, Decision Tree.

Abstract

The development of Internet of Things (IoT) and artificial intelligence technology has driven the increasing use of voice user interfaces (VUI) as a more natural form of human-computer interaction. One widely used VUI implementation is voice recognition-based smart speakers. Despite its widespread adoption, voice recognition performance on smart speakers is not necessarily optimal when used in real-world conditions, particularly in far-field scenarios that are influenced by user distance, environmental noise, and system response time. This study aims to analyze and compare the voice recognition performance of Amazon Alexa smart speakers and the Interactive Speaker System as a non-vendor comparison system. Testing was conducted at varying user distances in a non-soundproof room to represent real-world operational conditions.The obtained performance data was analyzed using the Random Forest method as a classification tool due to its ability to handle multivariate data and nonlinear relationships between variables. The results showed that variations in user distance significantly affected the voice recognition performance of both systems, with a tendency for performance to decrease as distance increased. In addition, differences in system architecture characteristics also influenced the level of resilience to environmental conditions. The application of the Random Forest method also enabled the identification of dominant factors that influence the success of voice recognition. This research is expected to provide theoretical contributions in the study of voice recognition performance in far-field scenarios, as well as practical contributions as a basis for consideration in the selection and development of more reliable voice-based interaction systems in real environments.

Abstract

This study compares the performance of the Temporal Convolutional Network (TCN) and Gated Recurrent Unit (GRU) models in predicting the price of Ethereum, which is important to support cryptocurrency investment strategies. With the high volatility of the cryptocurrency market, an accurate and reliable prediction model is needed. In this study, Ethereum's daily closing price data over four years was analyzed using TCN and GRU models to evaluate its predictive capabilities. Model accuracy is measured using Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and Mean Squared Error (MSE). The results showed that the TCN model excelled in average accuracy with lower MAE and MAPE values, while the GRU model showed excellence in reducing the impact of large errors with smaller MSE values. This reflects TCN's superiority in capturing the overall pattern of price movements, while the GRU is more responsive to short-term price fluctuations. These findings demonstrate the potential of both models in cryptocurrency price forecasting, with their respective advantages. This research provides valuable information for investors and researchers in developing predictive strategies in dynamic financial markets. A combination of TCN and GRU models can also be explored to improve prediction performance in the future.

Abstract

This study investigates the implementation of an analytical firewall on the Mikrotik Cloud Core Router (CCR) device for network protection against Domain Name System (DNS) and Synchronise Flood (SYN Flood attacks in the information technology infrastructure of the North Aceh Regency Government. DNS-based attacks and SYN Flood have demonstrated a significant disruptive capacity for the continuity of electronic public services, illustrating the urgency of robust security protocols on government infrastructure. The study implemented a quantitative-experimental approach, with methodological triangulation in empirical data acquisition through controlled attack simulations, firewall log analysis, and semi-structured interviews with technical personnel. Experiments are designed with variations in attack intensity to evaluate system resilience thresholds, while firewall log analysis facilitates the identification of anomalous patterns through detection algorithms. The analytics process applies parametric evaluation to temporal mitigation metrics, packet processing capacity, and operational implications on network performance, complemented by descriptive statistical analysis that explores data distribution and temporal trends. The results indicate the differential effectiveness of the specific firewall configuration against a specific attack typology, with an empirical determination of optimisation parameters for real-time mitigation. This research contributes to the corpus of knowledge regarding the security of government networks through the derivation of protective models that are adaptive to the operational characteristics of public infrastructure. The findings have substantive implications for cybersecurity policy formulation in the administrative context of local governments, with extensive significance for the implementation of network architectures that are resilient to volumetric attacks and protocol exploitation.
