Abstract

Spirometer is an instrument used to measure the vital capacity of the human lung and is usually only found in large hospitals or clinical laboratories because of its relatively high price. However, to find out how this instrument works, a prototype of the spirometer is made by utilizing a Labview-based interface. This prototype was developed by making an air channel or funnel the size of a human mouth which then the air will be detected by a pressure sensor connected to a signal conditioning circuit and then the measurement information data is forwarded by the Arduino to a computer to be processed into digital data which is then converted into vital capacity information data. lungs. The results obtained from this research are that it can make a spirometer prototype according to its function which is hoped to be used as a learning medium in the field of medical instrumentation by measuring the vital capacity of the lungs in the form of height, age, and gender of a person, besides that the results are in the form of a graphic display. and numerical data from the measurement process on the GUI display in LabVIEW. This prototype was calibrated using a syringe with a volume of 2 liters and the accuracy rate was 99.63% with a standard deviation value of ± 70.61 ml and a precision value of 1.76% from these results.

Abstract

The control of household electronic equipment can now be done remotely using a website, or better known as the smart home controller application to reduce waste of electricity usage. The electronic equipment that is controlled changes the lights and sockets. This electronic equipment controller website is made with the Laravel framework which uses the PHP 5.8 programming language which is closed, therefore a connection is made with the REST API that uses the Javascript programming language to bridge the communication between electronic equipment and the website. Delivery of data between the website and components requires a server and broker to broker data paths. Thus MQTT is needed as a means of exchanging data on the hardware side so it requires a gateway in the form of Node Js to connect PHP with MQTT. Test results are done by testing the speed of the lights using various internet connection media. The test results showed the fastest internet connection media, namely using a laptop connected to a WiFi internet network with an average speed of 0.691 seconds. The smart home controller website named Pantaw can be accessed using the UGM hotspot WiFi network.Keywords: Website, smarthome, MQTT, Laravel, Node Js.

Abstract

In electrical engineering, there are several power terms; active power, reactive power, instantaneous active power, instantaneous active power, instantaneous power, apparent power and complex power. Even though are used in daily activity, electrical practitioners are facing difficulty to explain those terms practically. This paper tries to solve those difficulty by interpret those term in practical way. Firstly, each power term are defined theoretically. Then those terms are presented mathematically. Next, power in single phase sinusoidal electric network is analyzed. Theoretical definition result is connected with power analysis result. Computer simulations are held to strengthen interpretation result. Considering the width of discussion area, this paper only covers most general application, that is single phase sinusoidal network.

Abstract

UAV formation is one of techology development in UAV world. The UAV formation can be utilized in various fields including agriculture, mapping and defense security (HANKAM). Communication is one of the important components in making UAV formations. To make UAV formations, position and direction data (AHRS) from each UAV will be sent to other UAVs so that when forming UAV formation, no collisions occur between UAVs. This study uses a star topology like the one on a computer network. This method involves two or more UAVs, both of which will exchange data. In this study the data sent is in the form of a dummy data package using the xbee module. The purpose of this study is the initial model of communication between UAVs which can later be developed into more complex communication models for many UAVs. The results obtained in the form of maximum communication distance between UAVs is 50m and the recommended optimal distance is 10-20m.

Abstract

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.

Abstract

The adventages of technology make every job easier, but this ease sometimes isn’t matched by safety factors. Security is vital to avoiding this technology being misused by uninvited people.This journal discusses the security of home doors with a microcontroller-based voice. The voice recognition process starts from the sound that propagates and then processes the corresponding easyvr sensor so that the easyvr sends a command to the relay to open the doorlock solenoid. From various tests obtained from voice recognition that can support the sound in the form of recordings, in speech recognition with an achievement level of 45 dB approved sound with an ideal pitch at 0-700 cm, it needs 75 dB sound amplifier with an ideal distance of 0-20 cm. For the percentage of success range with 30-40% different and the percentage of sound success is above 90%.Kemajuan teknologi membuat pekerjaan menjadi mudah, namun kemudahan tersebut tidak diimbangi dengan faktor keamanan. Keamanan menjadi hal yang vital untuk menghindari teknologi tersebut tidak disalahgunakan oleh orang yang tidak berwenang. Pada jurnal ini membahas pengaman pintu rumah dengan pengenalan suara berbasis mikrokontroler. Proses pengenalan suara dimulai dari suara yang merambat lalu diproses sensor easyvr jika sesuai sampling maka easyvr mengirimkan perintah kepada relay untuk membuka solenoid doorlock. Dari berbagai pengujian didapatkan bahwa pengenalan suara tidak dapat mengenali suara dalam bentuk rekaman, pada pengenalan suara dengan tingkat kebisingan 45 dB mengenali suara dengan ideal  pada jark 0-700 cm, kebisingan 75 dB mengenali suara dengan ideal pada jarak 0-20 cm. Tingkat persentase keberhasilan suara yang berbeda 30-40% dan persentase keberhasilan suara yang sama diatas 90%.
