The development of wireless sensor network (WSN) technology has progressed very rapidly. These developments also triggered the development of wireless modules used in WSN. Xbee and ESP8266 are wireless modules that are often used to design wireless sensor networks. Xbee uses the IEEE 802.15.4 standard while ESP8266 uses the IEEE 802.11 b / g / n standard. In this research will be comparison of wireless modules between Xbee and ESP8266 to test the performance of the wireless module. Comparison is performed by testing the value of throughput, delay packet, and packet lost. The test will be applied to the air quality monitoring system using the MQ135 sensor. The result of the research is the comparison of parameters tested from both wireless modules.

Change and Innovation continues as the times progress. Especially in the field of technology, one of which is the Internet of Things (IoT). With the existence of this technology, electronic devices can be connected to the internet. This will simplify the process of data transmission and device control. With this aim, the authors do research on the implementation of IoT technology on electronic devices, especially in the field of electricity. Electrical energy monitoring systems are used to detect the use of electrical energy used by the load. In this monitoring system, the measurement of the electric current using the current sensor. The measurement data made by the current sensor will be processed by the microcontroller. The research developed arduino-based monitoring systems and databases aimed at detecting and monitoring the use of electric current. In addition, it also performs analysis of data traffic from arduino devices and databases, to find out data delay, throughput or packet loss by using Wireshark.

Received Signal Level (RSL) Strength Assessment of 2.4 GHz in A Hotel Meeting Room Fauzi, Amar; Arrofiq, Muhammad

Publisher : Department of Electrical Engineering and Informatics, Vocational College, Universitas Gadjah Mada

This study aims to analyze the signal quality of the building profile factor at the Ballroom of Tentrem Hotel Yogyakarta, organized by the value of RSL (Received Signal Level) as an indicator of signal strength level of each access point of the Tentrem Hotel Ballroom meeting room, and calculate other parameters such as EIRP (Effective Isotropic Radiated Power), free space loss with theoretical and measurement levels. Receive level signals in the field using the Netsurveyor and Vistumbler applications installed on the laptop and the Wifi Overview and Wifi Analyzer app installed on the smartphone. From the results of both RSL calculations in theory and its changes. Damping factors in the field such as diffraction effect, refraction, reflection, absorption or blocking. The average field summary shows the RSL values in turn "very good" and "good" there is no "low" indicator, the connection in every meeting room of Tentrem Hotel Ballroom is good and normal. Will, found some problems in the field that can cause a decrease in signal quality so that efforts need to optimition. Keywords: Wireless Local Network, Received Signal Level, Effective Isotropic Activated Power, free space loss.

Investasi ilegal telah menjadi permasalahan serius di Indonesia, yang mengakibatkan kerugian finansial yang signifikan bagi investor dan perekonomian. Pengecekan legalitas perusahaan investasi secara manual belum efektif dan memakan waktu. Oleh karena itu, penelitian ini memanfaatkan teknologi machine learning dengan metode text classification untuk melakukan prediksi otomatis terhadap pesan investasi. Metode text classification digunakan dalam penelitian ini untuk mengategorikan pesan investasi berbahasa Indonesia dari media sosial, terutama Telegram, menjadi legal atau ilegal. Tujuan penelitian ini adalah merancang purwarupa sistem deteksi legalitas investasi. Dataset yang digunakan diperoleh dari media sosial Telegram, terdiri dari dua varian dengan jumlah 2996 data dan 210 data yang mencakup pesan investasi legal dan ilegal. Proses penelitian meliputi pengumpulan data, preprocessing, pelatihan model klasifikasi, evaluasi, dan pembuatan aplikasi web untuk deteksi pesan investasi. Dalam penelitian ini, dua algoritma, yaitu BiLSTM dan LSTM, diimplementasikan dan dibandingkan. Pengujian dilakukan dengan mempertimbangkan jumlah data dalam dataset, rasio pembagian dataset, penggunaan algoritma BiLSTM dan LSTM, confusion matrix, serta aplikasi web. Hasil pengujian menunjukkan bahwa model klasifikasi teks dengan algoritma BiLSTM dan jumlah data 2996 dengan rasio pembagian 70:30 memberikan performa tertinggi dibandingkan varian lain. Model dengan algoritma BiLSTM tersebut mampu mencapai akurasi sebesar 96%, presisi 98%, dan recall 93%. Aplikasi web berhasil mendeteksi pesan investasi menggunakan model dengan performa tertinggi dan berjalan sesuai dengan rancangan yang telah ditetapkan.
