Makalah ini menyajikan kendali heading pada trajectory tracking menggunakan sensor kompas dan global positioning sensor (GPS) pada miniatur robot mobil. Permasalahan yang timbul ketika miniatur robot mobil mengikuti lintasan ialah terjadinya slip pada roda. Oleh sebab itu menimbulkan kesalahan heading yang dapat diperoleh dari sensor kompas dan pembacaan posisi dari GPS pada miniatur robot mobil tersebut. Untuk meminimalisir permasalahan yang terjadi, kendali proporsional integral derivatif (PID) diterapkan untuk mengendalikan heading miniatur robot mobil dengan menggunakan metode ke-2 Ziegler Nichols. Dalam proses pencarian parameter dari kendali PID ini diperoleh dengan hasil Kp=0.6; Ti=2.5; dan Td=0.625. Selanjutnya, penerapan metode Haversine digunakan untuk menghitung jarak terpendek antara dua titik lintasan saat proses pembacaan posisi dari GPS. Dari hasil pengujian diperoleh bahwa kendali PID dan metode Haversine mampu membuat pergerakan miniatur robot mobil sukses mengikuti lintasan uji.

The postpaid KWH Meter reading by officers is sometimes constrained to reach the physical KWH Meter because the house fence is locked or the KWH Meter is inside the house. This often causes problems such as reading errors and the officer must come to the customer several times. Therefore a telemonitoring system for KWH Meters is made through an online WiFi network to help officers record electricity usage for consumers. This system uses ACS712 current sensor, ZMPT101B voltage sensor, different phase sensor, RTC DS1307 as a timer and date, Arduino as a data processor, Micro SD Card for storing date, time, and sensor readings, LCD as a viewer, and transmitted with modules ESP8266 Wi-Fi to a smartphone or PC with a simple web display. The test results show that all components can function properly. ACS712 30A current sensor has an average error of 1%, and the ZMPT101B voltage sensor is capable of carrying out voltage readings in load or no load conditions with an average error of0.5% and a different phase sensor has an average error of 1% for resistive load and 4.2% for inductive loads of TL lights. Power measurements have an average error of 1.3% for 75W incandescent lamp loads and 300W irons. The ESP8266 Wi-Fi module emits a maximum of 15 meters when not blocked and 10 meters when blocked. All measurement data can be stored on the SD Card.

Light or sunlight can be converted into electricity using solar panel technology. The measurement process is needed on current and voltage parameters to determine whether a solar panel is working correctly or not. The application of the Internet of Things (IoT) is a suitable method for monitoring efficiency measurements on solar panel performance in real-time by combining several computational components, protocols, and sensors to interact more quickly and help all activities become more efficient. One IoT technology that can work efficiently is the Long Range Wide Area Network (LoRaWAN). LoRa communicates using radio frequencies with a wide coverage range and has a low power consumption level. In this study, the implementation of LoRaWAN technology as a communication protocol between three series of nodes and one gateway in building a solar panel system is then visualized on a web that can monitor currents and voltages in the form of graphs and numbers. Displays notifications when there is a change in the condition of the large voltage from the solar panel can control the state of turning on or off the lights and turning off the whole node, and displaying a history of current and voltage readings. The functionality of the system will later be tested using black-box testing. There was also a distribution of questionnaires to 35 respondents to measure the level of agreement that the system designed was running well.

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.

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.

Robotika dalam aspek kehidupan manusia dewasa ini sangatlah penting. Tidak terkecuali pada bidang milter. Saat ini banyak negara berlomba-lomba menunjukkan kemuktahiran robot ciptaannya dalam bidang militer. Indonesia merupakan negara dengan prajurit tempur yang cukup disegani di tingkat Asia, sebut saja Kopasus (Komando Pasukan Khusus). Satuan prajurit Tentara Nasional Indonesia (TNI) ini sangat handal di dalam pertahanan darat Indonesia. Namun hal ini tidak cukup, saat ini banyak negara-negara melibatkan robot sebagai sarana bantu para prajuritnya. Hal ini lah yang mendorong peneliti untuk ikut mengambil peran dalam membantu para prajurit Indonesia nantinya dalam hal surveillance atau pengamatan dengan bantuan sebuah robot. Peneliti merancang dan mebuat sebuah prototype atau purwarupa robot mainland surveillance yang akan digunakan pada prajurit tentara darat. Tahap awal perancangan mekanisme gerak robot merupakan menjadi titik konsern peneliti. Dengan menggunakan roda platform mecanum wheel, robot mainland surveillance diharapkan memeliki navigasi yang memungkinkan dapat bergerak kesegalah arah.
