Abstract

Kinerja akademik siswa merupakan indikator penting keberhasilan belajar, namun penilaian konvensional sering kali belum optimal dalam memanfaatkan data kebiasaan dan gaya hidup siswa. Penelitian ini bertujuan untuk mengklasifikasikan nilai ujian siswa (Rendah, Sedang, Tinggi) berdasarkan kebiasaan belajar menggunakan algoritma K-Nearest Neighbor (kNN) dan Support Vector Machine (SVM), serta membandingkan performa keduanya. Data sebanyak 1000 entri siswa dari Kaggle.com diolah melalui tahap pra-pemrosesan yang meliputi diskritisasi nilai ujian menjadi kategori dan pemilihan fitur yang relevan, seperti jam belajar, persentase kehadiran, waktu tidur, dan peringkat kesehatan mental. Pembagian data dilakukan dengan random sampling (90% training dan 10% testing) yang diulang 10 kali. Hasil evaluasi menunjukkan kNN dengan N=10 mencapai akurasi tertinggi 0.982. Sementara itu, SVM dengan kernel Linear memperoleh akurasi 0.974 , diikuti RBF dengan 0.939 , dan Polynomial dengan 0.946 , sedangkan kernel Sigmoid hanya 0.712. Performa terbaik kNN (N=10) lebih lanjut dikonfirmasi melalui confusion matrix, menunjukkan tingkat kesalahan klasifikasi yang sangat rendah dan prediksi yang konsisten. Penelitian ini menyimpulkan bahwa algoritma k-NN, khususnya dengan N=10, adalah pendekatan yang paling akurat dan efektif untuk klasifikasi nilai ujian berdasarkan kebiasaan siswa, mendukung pihak sekolah dalam prediksi dan perencanaan pendidikan yang lebih baik.

Abstract

Engineering optimization problems often involve nonlinear objective functions, which can capture complex relationships and dependencies between variables. This study focuses on a unique nonlinear mathematics programming problem characterized by a subset of variables that can only take discrete values and are linearly separable from the continuous variables. The combination of integer variables and non-linearities makes this problem much more complex than traditional nonlinear programming problems with only continuous variables. Furthermore, the presence of integer variables can result in a combinatorial explosion of potential solutions, significantly enlarging the search space and making it challenging to explore effectively. This issue becomes especially challenging for larger problems, leading to long computation times or even infeasibility. To address these challenges, we propose a method that employs the "active constraint" approach in conjunction with the release of nonbasic variables from their boundaries. This technique compels suitable non-integer fundamental variables to migrate to their neighboring integer positions. Additionally, we have researched selection criteria for choosing a nonbasic variable to use in the integerizing technique. Through implementation and testing on various problems, these techniques have proven to be successful.

Abstract

PT Indomitra Global is a company engaged in electrical contracting services and provides various types of electrical panels needed by clients. Electrical panels require many important materials, for example mcb, sockets, cables, and many other important components. The material inventory system carried out at PT Indomitra Global still uses a manual method in the material inventory system. This process has several obstacles, namely not having a centralized database that makes material inventory data vulnerable to loss and there are often differences in the suitability of the amount of material in the warehouse with the amount in Microsoft Excel, because data management is still not easy enough and due to human error or input errors. On the basis of this problem, a web-based material inventory application was made using the Rapid Application Development (RAD) method. The material inventory system produced in this study is able to handle material data management which previously was still not easy enough to do, such as searching for data, managing incoming and outgoing material transaction data and making it easier to generate incoming and outgoing material reports based on time periods

Abstract

Quality of Service in a network is a big thing that must be resolved and dealt with as best as possible. The limitation of the maximum transfer rate in network devices creates an obstacle in the process of transferring data packets. To maximize the transfer rate in network devices, you can use Virtual Link Aggregation which can offer bandwidth optimization and failover in the network. Link aggregation is a solution in combining several physical links into one logical link. The method used in this research is to consider the allocation of bandwidth, load balancing and failover in the link aggregation. From the results of the link aggregation test using two (2) interface bonding, the results of the bandwidth averages when there is a UPD data packet transfer to 0 bps / 184.9 Mbps, which was previously around 0 bps / 91.6 Mbps. While the result of the bandwidth averages when the TCP data packet transfer occurs is 0 bps / 105.5 Mbps, which was previously around 0 bps / 93.8 Mbps. Link Aggregation using a Mikrotik Router is a solution to produce a larger Throughput Bandwidth by combining two (2) Ethernet Physical Links into one logical link.

Abstract

Edge computing has transformed data processing by moving computation closer to the source, enabling real-time analysis and decision-making. Edge devices are decentralized, which creates privacy and confidentiality concerns, especially when applying machine learning algorithms to sensitive data. Privacy-preserving machine learning methods for edge computing are examined in this research. Federated learning, homomorphic encryption, differential privacy, and secure aggregation are examined as data protection methods for network edge machine learning. A thorough study of these methods shows the challenges of balancing privacy, computational economy, and model correctness. Federated learning has promise for collaborative model training without raw data sharing, but communication overhead and convergence speed remain. A fictional healthcare use case shows how federated learning may be used to train collaborative models across many edge devices while protecting patient data. The case study stresses the necessity for sophisticated optimizations to overcome edge device limits and regulatory compliance. Federated learning algorithms, privacy-preserving procedures, and ethics must be improved, according to the research. Future directions include improving heterogeneous edge algorithms, addressing data ownership and consent ethics, and increasing model decision-making openness. This paper presents essential insights on privacy-preserving machine learning in edge computing and advocates for robust techniques for different edge environments. The paper emphasizes the importance of technological advances, ethical frameworks, and regulatory compliance for secure and privacy-aware machine learning in decentralized edge computing
