Abstract

This study aims to evaluate the performance of two IPv6 routing protocols, namely EIGRP and RIPng, based on Quality of Service (QoS) parameters such as throughput, packet loss, and delay on a network with a configuration of two routers and five routers. The method used is Design Science Research Methodology (DSRM), which includes literature review, network simulation design, data collection, and analysis. Tests were conducted using the EVE-NG simulator and Wireshark to analyze network traffic. The results show that EIGRP has a higher throughput than RIPng, with an average throughput of 3910 bit/s on two routers and 4118 bit/s on five routers, while RIPng recorded a throughput of 3594 bit/s and 4090 bit/s on the same configuration. In addition, EIGRP also showed a lower delay of 999 ms in both configurations, compared to RIPng which recorded a delay of 1570 ms for two routers and 1530 ms for five routers. Both protocols had similar results on the packet loss parameter (0%). These findings indicate that EIGRP is more efficient in maintaining throughput stability and reducing delay, thus it is superior in providing responsive network performance, even with a larger number of routers.

Abstract

This research aims to evaluate the performance of a Hyperledger Fabric-based blockchain system implemented for digital diploma management. The system is tested using the Caliper benchmark tool in various network and scalability scenarios, including normal conditions (baseline), network delay of 50ms, 100ms, 200ms, and 500ms; packet loss of 1%, 5%, 10%, and 15%; bandwidth limitation of 5 Mbps; high transaction load (scalability standard and scalability optimized); and extreme conditions in the form of Byzantine attacks with malicious nodes of 10%, 30%, and 50%. The evaluation was conducted using four key metrics: transaction success rate, failure rate, average transaction latency, and throughput (TPS). The system recorded high performance under normal network conditions with a success rate of 99.8%, latency of 0.89 seconds, and throughput of 9.7 TPS. Network disruptions such as delay, packet loss, and bandwidth limitation had only a minor impact, with the success rate remaining above 99% and latency gradually increasing. High load in the scalability scenario caused latency to increase to 27.21 seconds and failure rate to rise, but improved significantly after chaincode optimization. Meanwhile, the Byzantine scenario showed a drastic drop in performance with the success rate decreasing to 12.83% and the failure rate increasing to 87.17%. These results show that the Hyperledger Fabric-based digital diploma management system is resilient to common network disruptions and reliable at medium scale, but still requires strengthening the consensus mechanism to deal with extreme conditions and maintain reliability in environments that are not fully trusted.

Abstract

Penelitian ini bertujuan untuk memahami pengaruh frekuensi sampling terhadap masalah aliasing dalam pengolahan sinyal digital menggunakan MATLAB. Penelitian ini dilakukan melalui eksperimen dengan menguji tiga skenario yang berbeda, yaitu visualisasi sinyal, pemrosesan audio, dan penerapan penyaringan dengan Low-Pass Filter (FIR). Hasil penelitian menunjukkan bahwa masalah aliasing cenderung terjadi pada frekuensi rendah, namun dapat dikurangi dengan meningkatkan frekuensi sampling. Penggunaan frekuensi sampling yang lebih rendah menghasilkan audio yang kurang jelas dan terdistorsi, sementara frekuensi sampling yang lebih tinggi menghasilkan hasil yang lebih jernih dan berkualitas. Penerapan Low-Pass Filter (FIR) berhasil mengurangi efek aliasing yang terjadi. Temuan ini menggarisbawahi pentingnya pemilihan frekuensi sampling yang tepat untuk menghindari masalah aliasing dan memastikan kualitas sinyal yang optimal dalam pengolahan sinyal digital. Penelitian ini memberikan panduan praktis bagi para pengguna MATLAB dalam memilih parameter sampling yang sesuai untuk menjaga integritas dan kejelasan sinyal digital. Kesimpulannya, pemilihan frekuensi sampling yang tepat sangat penting untuk mencegah gangguan aliasing dan memastikan hasil yang akurat dalam aplikasi pengolahan sinyal digital. Dengan demikian, penelitian ini memberikan wawasan berharga bagi pengembangan teknologi pengolahan sinyal yang lebih baik di masa depan.

Abstract

Kemajuan teknologi telekomunikasi, khususnya jaringan 4G atau LTE (Long Term Evolution), telah mengubah dunia komunikasi seluler secara signifikan. Namun, dengan meningkatnya penggunaan layanan 4G LTE sering kali diikuti oleh gangguan sinyal yang cukup mengganggu. Studi ini menggunakan metode literature review dengan menggali data yang ada sebelumnya, diikuti dengan analisis dan eksplanasi rinci untuk melengkapi penelitian sebelumnya. Penelitian ini berfokus pada berbagai tingkat modulasi, termasuk QPSK, 16-QAM, 64-QAM, dan 256-QAM. Parameter utama yang diamati adalah throughput, yang merupakan ukuran utama untuk mengevaluasi efisiensi teknik pengiriman data dalam berbagai kondisi. Hasilnya menunjukkan bahwa modulasi tingkat tinggi, seperti 256-QAM dan 64-QAM, menunjukkan nilai throughput  yang lebih tinggi dibandingkan dengan modulasi QPSK. Diharapkan bahwa penelitian ini akan memberikan gambaran umum tentang hubungan antara modulasi dan teknologi 4G LTE.
