INTISARIAntena adalah perangkat yang sangat penting dalam teknologi penyampaiian informasi. Oleh karena itu, pada zaman sekarang ini Beragam jenis antena telah banyak dikembangkan, salah satunya adalah antenna mikrostrip. antenna mikrostrip ini memiliki banyak keunggulan sehingga sering digunakan dalam berbagai perangkat seluler. Semakin bertambahnya pengguna perangkat seluler membuat banyaknya penggunaan spektrum frekuensi untuk komunikasi seluler. Salah satu frekuensi yang banyak digunakan adalah frekuensi 900 MHz untuk sistem GSM. Dalam jurnal ini menyajikan mengenai perancangan antenna mikrostrip yang dapat digunakan dalam Sistem GSM.. Antena ini dibuat dengan bahan substrat epoxy dengan Konstanta dielektrik (Îµr)=4.4 dan ketebalan 1.6 mm serta menggunakan saluran pencatuan feed line. Penambahan element menjadi antena array memiliki tujuan untuk meningkatkan nilai gain antena agar dapat meningkatkan daya yang diterima oleh pengguna jaringan dan dapat menambah jarak jangkauan dari BTS menuju perangkat seluler. Dari hasil pengukuran langsung dilaboratorium, didapatkan karakteristik dari antena yang dibuat memiliki besar return loss -11.077 dB, VSWR 1.775, gain 6.8 dBi. Kata kunciâ€” Antena mikrostrip, Gain, Return loss, VSWR, pola radiasi, Linear arrayÂ ABSTRACTAntennas are very important devices in information delivery technology. Therefore, in this day and age various types of antennas have been developed, one of which is a microstrip antenna. This microstrip antenna has many advantages so it is often used in various cellular devices. The increasing number of mobile device users makes a lot of use of the frequency spectrum for cellular communication. One frequency that is widely used is the 900 MHz frequency for GSM systems. In this journal, it presents the design of microstrip antennas that can be used in GSM systems. This antenna is made with epoxy substrate material with dielectric constant (Îµr) = 4.4 and thickness of 1.6 mm and using feed line rationing channels. Adding an element to an array antenna has the purpose of increasing the antenna gain value so that it can increase the power received by network users and can increase the range of distance from the BTS to the mobile device. From the results of direct measurements in the laboratory, it was found that the characteristics of the antenna made had a large return loss of -11.077 dB, VSWR 1.775, gain 6.8 dBi.Keywords : microstrip antenna, Gain, Return Loss, Radiation Pattern, Polarization

Facial recognition system is a system developed by many technology companies. Face recognition has become a system that is widely used for various purposes such as the development of security systems, identification of identities, as well as processing of an image or film. One of the methods used to create this system is to use the ESP32 CAM module which is connected to the Arduino, where the ESP32 CAM is a module with an OV2640 camera sensor that can be used to take pictures and face recognition. ESP32 CAM is a development of the previous module and has an ESP32 chip with dual connectivity namely WiFi and Bluetooth. The face which is a part of the human body that is often the focus of attention in social interactions because it plays a vital role by showing identity and emotions. Will be used as an indication of the introduction of a person or Face Recognition. The basic principle is that by quoting the face's unique information, the system will read and recognize it. Face recognition is a pattern recognition (pattern recognition). This can be described as a classification of a face whether recognized or not recognized, and once recognized, the face pattern will be stored. The ESP32 CAM that has been connected to the Arduino will detect whether the face is recognized or not, then the data will be sent to the relay and if the face is recognized, the door lock will open automatically, while if the face data is not recognized, the door lock will not open.

WBAN (Wireless Body Area Network) technology is used in this study to provide an integrated health monitoring platform. The device utilizes MLX90615 for measuring body temperature, a Blood Pressure Sensor for measuring blood pressure and pulse rate, and a MAX30102 Sensor for measuring blood oxygen and blood glucose levels. The output of this utility is displayed on an OLED screen and is controlled by the NODEMCU ESP8266. The test reveals an accuracy of 94.8%, indicating that the instrument can provide accurate results and has a relatively low error rate on each sensor.

Security is something that must often be ignored by most people and think it is safe, but it turns out that someone can still lose their valuables. In this final project, we will design an Internet of Things (IoT)-based smart door access tool that uses a fingerprint and pin password using the Optical Scanner Sensor method. The purpose of making and designing a smart door tool based on the Internet of Things (IoT) is one of them to apply the optical method as a method used to recognize fingerprint biometric identification. By using a smartphone (android) as a controller using the NodeMCU contained in the ESP2866 WiFi module via an internet connection connected to an application made with MIT App Inventor. In the application of fingerprint sensors using the optical method, the scanning process is obtained through finger scanning based on the effect of light reflection that occurs on the optical sensor on the fingerprint. So as to produce digital image retrieval on identified fingerprints. The communication that uses the fingerprint sensor and Arduino uno as a data processing unit uses serial data communication. When the command has run according to its function, the results of the data obtained enter in realtime at the data processing place.

The development of information technology in this modern era has progressed very rapidly, many ways have been developed to store large amounts of data, one of which is to use a server. A server is a computer system that serves and controls client access that is connected to it. All activities that we do on the internet always involve the server. Servers play a very important role because of their heavy duty to serve clients. Therefore, the server may not experience interference. One of the disturbances that cause a damaged server is the temperature that is too hot so that this tool is made in order to prevent these problems. This tool is made to regulate the temperature and humidity of the server room that exceeds reasonable limits. This tool is made using Arduino Uno as a microcontroller, DHT11 as a temperature and humidity sensor, Ethernet shield as a link to the internet. This tool also uses the Blynk application as monitoring, from the results of reading temperature and humidity sensors on this device can reduce the temperature by 6˚C cooler when the temperature in the room is hot, in this case the tool functions as it should

There are so many cases that occur at home when the house is empty or being abandoned by its occupants, the impact of the theft is very detrimental to victims who have broken into their homes, these incidents often occur by damaging or breaking into the lock system on the doors and windows of the house. This theft causes unrest in the community because they feel less calm, safe, and comfortable when outside the home. In this study, an application was designed to make it easier to control the house with the use of IoT in creating an android-based information system that was applied to assist security guards in monitoring guests in real time. In this study, the information system used is facial recognition, where if there is a face that is not recognized or dangerous, the system will send a face image to the security guard android smartphone application.
