In this paper RT / RW-Net has been designed and realized as a system to access the internet network. The system was built using the Mikrotik Router as an operating system, access point as a network distributor, and an omnidirectional antenna as transmitter and receiver of Wi-Fi signals. The user manager feature on the proxy plays a role in managing several functions such as bandwidth limitation and quota limitation. Quotas and grace periods can be made according to customer requests. The network is tested when the customer is connected to the RT / RW-Net hotspot automatically on the customer's device the RT / RW-Net page will appear to enter the username and password that has been given by the administrator. The system is tested by measuring the RSSI value (Receive Signal Strength Indicator) to determine signal quality based on applicable standards. Based on the test results, the lowest RSSI value is -65 dBm at a distance of 280m to the west with a note that there is no obstacle in the omnidirectional antenna to the customer's device. This system can also inform the remaining quota status and active period to the customer on the RT / RW-Net homepage.

ABSTRAKKondisi kendaraan yang saling bergerak pada sistem komunikasi Vehicle-to-Vehicle (V2V) menyebabkan daya sinyal yang diterima berfluktuasi. Selain itu, dengan adanya pergeseran frekuensi Doppler mengakibatkan semakin sulitnya menjaga level Bit Error Rate (BER) kurang dari 0,001. Mengubah threshold channel gain pada modulasi adaptif adalah salah satu metode yang dapat diterapkan untuk menjaga level performansi tanpa mengorbankan nilai Signal to Noise Ratio (SNR). Sayangnya threshold yang memberikan SNR optimal belum diketahui. Pada penelitian ini digunakan algoritma random forest regression untuk mencari nilai threshold channel gain demi didapatkannya nilai SNR terbaik. Dari hasil prediksi dengan jumlah estimator sebanyak 7, didapatkan threshold 0.1Â dan 0.3 hanya membutuhkan SNR sebesar 25.59 dB untuk menjaga BER di level< 0.001.Kata kunci: Modulasi Adaptif, Pergeseran Doppler, Random Forest RegressionÂ ABSTRACTThe condition of the moving vehicles in the Vehicle-to-Vehicle (V2V) communication system leads to fluctuating received signal power. In addition, the Doppler shift increases the difficulty to maintain the Bit Error Rate (BER) less than 0.001. Changing the channel gain threshold in adaptive modulation is one method that can be applied to maintain the performance level without sacrificing the Signal to Noise Ratio (SNR) value. Unfortunately, the threshold that provides the optimal SNR is not yet known. In this research, a random forest regression algorithm is used to determine the channel gain threshold in order to obtain the best SNR value. Based on the prediction results the number of estimators of 7, it is obtained that the thresholds of 0.1 and 0.3 only require an SNR of 25.59 dBÂ to keep the BER at the level < 0.001.Keywords: Adaptive Modulation, Doppler Shift, Random Forest Regression

ABSTRAKKomunikasi Vehicle to Infrastructure (V2I) memungkinkan kendaraan dapatÂ terhubung ke berbagai macam infrastruktur. Dengan kondisi kendaraan yangÂ bergerak, maka kondisi lingkungan yang dilewati mempengaruhi parameterÂ komunikasi. Implementasi modulasi adaptif pada skema V2I memperbolehkanÂ sistem menggunakan skema modulasi yang berbeda untuk mengakomodasiÂ perubahan kondisi lingkungan. Pada penelitian ini digunakan skema modulasiÂ QPSK, 8PSK, dan 16-QAM dengan memanfaatkan reinforcement learning danÂ algoritma epsilon greedy untuk menentukan skema modulasi yang digunakanÂ berdasarkan level AWGN. Dari hasil simulasi dengan kondisi nilai epsilon yangÂ divariasikan dari 0.1 hingga 0.5 didapatkan bahwa semakin tinggi nilai epsilonÂ maka semakin sering agen tidak memilih skema modulasi dengan reward tertinggi.Kata kunci: Reinforcement learning, Modulasi Adaptif, AWGNÂ ABSTRACTVehicle to Infrastructure (V2I) communication allows vehicles to be connected toÂ various infrastructures. Under the scenario of a moving vehicle, the environmental conditions which is passed by the vehicle will affect the communication parameters. The adaptive modulation implementation in the V2I scheme allows the system to use different modulation schemes to accommodate changing environmental conditions. In this study, the QPSK, 8PSK, and 16-QAM modulation schemes were used by utilizing reinforcement learning and the epsilon greedy algorithm to determine the modulation scheme used based on AWGN level. From the simulation results with the conditions of the epsilon value varying from 0.1 to 0.5, it is found that the higher the epsilon value, the more often the agent does not choose the modulation scheme with the highest reward.Keywords: Reinforcement learning, Adaptive Modulation, AWGN

Human activity recognition systems can be used for various purposes such as monitoring, authentication, and telemedicine. In this research, a non-invasive, high privacy, easy to implement, and affordable human activity recognition system based on WiFi and deep learning is developed. Sixteen activities; including upper body, lower body, and whole body movement; were recognized by utilizing Channel State Information (CSI) contained in the WiFi signal. Measurements were carried out in an empty room with dimensions of 6*8 m with the distance between the transmitter and receiver being 1, 3 and 6 meters from the subject. Google Teachable Machine is used to recognize activities carried out. From the measurement result, the accuracy shows more than 97%. It is also evident that the further the measurement distance, the worse the recognition results. This is due to the increasing amount of noise in the radio channel as the distance increases.
