ABSTRAK
Tingginya pertumbuhan traffic data serta munculnya fitur dan teknologi terbaru seperti internet of thing IoT , mendesak munculnya teknologi komunikasi seluler generasi kelima 5G . Channel coding memiliki peran penting untuk mendukung tiga skenario 5G, yaitu Enhanced Mobile Broadband eMBB , Massive Machine Type Communications mMTC dan Ultra Reliable Low Latency Communication URLLC . Ada tiga kandidat channel coding yang berpotensi untuk memenuhi standar teknologi 5G, seperti yang diidentifikasi oleh 3GPP, yaitu turbo code, low density parity check LDPC code dan polar code.Penelitian ini mensimulasikan dan membandingkan kinerja polar code dan LDPC code berdasarkan parameter yang sesuai dengan skenario mMTC. Evaluasi teknis dilakukan dengan menilai BLER / BER dan coding gain untuk block length yang rendah dengan modulasi QPSK. Hasilnya menandakan bahwa polar code SCL decoder memiliki performa paling unggul dengan nilai coding gain 8.3 dB - 10 dB. Selain itu, polar code SCL decoder juga memiliki nilai Eb/N0 yang lebih kecil dengan perbedaan 1 dB - 3 dB dibanding skema pengkodean lainnya untuk mendapatkan BLER 0.0001. Namun jika ditinjau dari kompleksitas dan waktu decoding, polar code SC decoder mengungguli skema pengkodean lainnya dengan kompleksitas O n log n dan waktu decoding 0.005 s untuk block length 64 bit serta 0.029 s untuk block length 512 bit.

"Dimasa Mendatang, diprediksi akan banyak perangkat yang terhubung pada jaringan komunikasi, selain itu jaringan komunikasi masa depan juga membutuhkan nilai packet loss rate (PLR) yang rendah serta sistem pemrosesan yang sangat cepat. Pada penelitian ini diusulkan sebuah skema akses jamak atau multiple access yang mampu melayani lalulintas komunikasi dengan jumlah perangkat yang sangat banyak  serta nilai PLR yang kecil. Skema akses jamak berupa coded random access (CRA) dipilih dalam penelitian ini karena mampu melayani lalulintas komunikasi dengan jumlah perangkat yang terhubung sangat banyak (throughput yang tinggi. Untuk mendapatkan PLR yang rendah pada CRA, digunakan degree distribusi  yang menghasilkan stopping set sedikit. Sehingga pada penelitian ini dilakukan optimasi pada CRA dengan mencari degree distribusi yang menghasilkan stopping set paling rendah pada throughput yang masih dapat diterima. Optimasi dilakukan dengan menggunakan theory probability stopping set dan simulasi komputer. Untuk memvalidasi ketercapaian throughput, pada penelitian ini dilakukan evaluasi dengan menggunakan metode Extrinsic Information transfer(EXIT) chart analisis. Dalam penelitian ini juga dilakukan validasi antara theory probability stopping set dengan hasil yang didapat dari simulasi komputer. Dari hasil validasi tersebut menunjukan theory probability stopping set sesuai dengan hasil dari simulasi komputer. Sehingga penggunaan theory probability stopping set cukup valid untuk dipakai pada optimasi degree distribusi dengan meminimalkan stopping set. Dari serangkaian penelitian yang dilakukan, didapatkan CRA dengan degree distribusi yang mempunyai stopping set paling minimal sebanyak 48 kali dalam 10.000 sample yang ditandai dengan PLR yang cukup rendah yaitu 10^-3 pada G=0.65 packet per slot (yang artinya 1 paket rusak dalam 1000 sampel dengan mode pengiriman 65% aktif dari seluruh user dan throughput yang masih dapat diterima yaitu G=0.7 packet per slot. Usulan CRA dengan degree distribution optimal dengan minimal stopping set hasil dari penelitian ini diharapkan dapat diterapkan dan bermanfaat pada komunikasi aplikasi krusial dengan nilai kegagalan mendekati nol.

The Future networks predicted with massive number of devices connected to communication networks, beside that the future communication network also requires a low value of packet loss rate (PLR) and a very fast processing system. In this paper, a multiple access scheme is proposed which is capable of serving communication traffic with a very large number of devices and a small PLR value. Multiple access scheme such as coded random access (CRA) were in this paper, because of ability of serving communication traffic with a large number of connected devices(or we can call high throughput needed). To obtain a low PLR in CRA, we use a degree distribution which resulted in a small number of stopping set. This paper was optimized on CRA by looking for a degree distribution that produced the lowest number of stopping set at acceptable throughput. Optimization was done by using probability of stopping set theory and computer simulation. To validate the achievement of throughput, this paper was evaluated using the Extrinsic Information Transfer (EXIT) chart analysis. In this paper, we validate between probability stopping set theory and the results obtained from computer simulations, the result shows that the probability stopping set theory is in accordance with the result of computer simulations. Therefore the use of probability stopping set theory is valid to be used in degree distribution optimization by minimizing stopping sets. In this paper, it was obtained CRA with a degree distribution which has a stopping set of at least 48 times in 10000 samples which is marked by PLR which is quite low at 10-3 at offered traffic 0.65 packet per slot (which means 1 packet is damaged in 1000 samples with delivery mode 65% active of all users) and acceptable throughput in 0.7 packet per slot. The proposed CRA with optimal degree distribution having minimum stopping set results from this paper is expected to be applicable and useful in crucial application communication with asymptotically zero failure."

The business model that will be used is using the St. business model. Gallen Magic Triangle as a tool for analyzing business model components in IoT business development. Data is obtained from various literary sources along with interviews with several cellular operators in Indonesia for IoT implementation. In general, the IoT business model implemented by cellular operators has led to platform providers as a first step to developing the IoT ecosystem in stages. In heading to the ideal condition to be an end-to-end provider, a strategy is needed in the business components of the model used. The results of the study show that there is a need to strengthen the development of the platform that has now been developed by strengthening the development of the strategy for the desired revenue model in an effort to implement various IoT business monetization strategies and efforts to increase the value proposition offered to customers. Recommendations that can be conveyed are cellular operators that regularly carry out internal or external investment analysis in order to improve the company's capability to accelerate its special role in the IoT supply business and analyze technology roadmaps and platform development towards the establishment of ecosystems with telecommunications operators as digital hub enablers."

"Internet of Things (IoT) merupakan sebuah teknologi yang memungkinkan perangkat untuk berkomunikasi dan mengirimkan data melalui jaringan tanpa campur tangan manusia. Kompleksitas pada jaringan IoT menyebabkan sistem mengalami kesulitan dalam mendeteksi properti serangan dan memaksa sistem untuk memperkuat keamanannya. Salah satu upaya yang paling sering digunakan untuk pertahanan jaringan IoT adalah Intrusion Detection System (IDS). Penggunaan IDS dapat memberikan peringatan dini dan mampu melakukan pencegahan terhadap potensi serangan pada jaringan. Penelitian ini menggunakan dataset Aegean WIFI Intrusion Dataset (AWID2) yang berisikan lalu lintas trafik internet pada jaringan WIFI. Data AWID2 berisi 2,3 juta records dan dikelompokkan ke dalam empat kelas yaitu normal, impersonation, injection, dan flooding. Penelitian ini dilakukan untuk melakukan klasifikasi jenis serangan siber pada jaringan IoT melalui penerapan teknik machine learning dengan metode Whale Optimization Algorithm – Support Vector Machine (WOA-SVM) dengan kernel RBF dan pendekatan One vs Rest, dimana Whale Optimization Algorithm (WOA) digunakan sebagai optimasi parameter yang digunakan pada metode Support Vector Machine (SVM). Untuk mengatasi permasalahan dimensi data yang tinggi pada dataset yang digunakan, dilakukan seleksi fitur untuk reduksi dimensi data dengan menggunakan metode seleksi fitur filter Information Gain. Kinerja model dievaluasi berdasarkan nilai metrik accuracy, precision, recall, dan F1 Score dengan memperhatikan waktu klasifikasi dan proprosi train-test split berkisar dari 50%-90%. Hasil penelitian menunjukkan bahwa model WOA-SVM memperoleh kinerja terbaik dengan menggunakan 40 fitur terbaik dari hasil seleksi fitur Information Gain menghasilkan tingkat accuracy sebesar 99,5951%, precision sebesar 96,3928%, recall sebesar 99,8888%, F1 Score sebesar 98,0662%, dan waktu klasifikasi selama 16,831 detik. Hasil kinerja model WOA-SVM tersebut lebih baik jika dibandingkan dengan tanpa menggunakan seleksi fitur dan SVM tanpa optimasi parameter WOA.

The Internet of Things (IoT) is a technology that enables devices to communicate and transmit data over a network without human intervention. The complexity of IoT networks poses challenges in detecting attack properties and necessitates enhanced security measures. One of the most commonly employed defenses for IoT networks is the Intrusion Detection System (IDS). The use of IDS provides early warnings and can prevent potential attacks on the network. This study utilizes the Aegean Wi-Fi Intrusion Dataset (AWID2), which contains internet traffic data on Wi-Fi networks. The AWID2 dataset comprises 2 million records categorized into four classes: normal, impersonation, injection, and flooding. This research aims to classify types of cyber-attacks on IoT networks by applying machine learning techniques using the Whale Optimization Algorithm - Support Vector Machine (WOA-SVM) method with an RBF kernel and a One vs. Rest approach. The Whale Optimization Algorithm (WOA) is used to optimize the parameters employed in the Support Vector Machine (SVM) method. To address the high-dimensional data issue in the dataset, feature selection is performed to reduce data dimensions using the Information Gain filter method. The model's performance is evaluated based on the metrics of accuracy, precision, recall, and F1 Score, considering computation time and train-test split proportions ranging from 50% to 90%. The results indicate that the WOA-SVM model achieves the best performance by using the top 40 features from the Information Gain feature selection, yielding an accuracy of 99.5951%, precision of 96.3928%, recall of 99.8888%, F1 Score of 98.0662%, and a computation time of 16.831 seconds. The performance of the WOA-SVM model is superior compared to models without feature selection and SVM without WOA parameter optimization."
