Abstract

The purpose of this study was to determine the potential for seismic hazard based on the peak ground acceleration value in the North Konawe office area. This study uses the HVSR method to obtain the dominant frequency, amplification factor, dominant period, seismic vulnerability index and Peak Ground Acceleration. The results obtained from the microzonation of the distribution of the dominant frequency value with a high category were found at 5 measurement points, the amplification factor with a low category was found at 1 measurement point, the dominant period with a low category was found at 6 measurement points and the seismic vulnerability index with a low category was found at 5 points. measurement. Overall the research area is included in the level of seismic hazard risk, not high potential but in the low category. While the microzonation of the distribution of PGA values ​​obtained values ​​ranging from 23,2381-23,3231 gal which belong to the low seismic hazard risk level. Where it can be described in this area the earthquake that occurred can be felt by many people but caused damage. The light objects that were hung swayed and the windows shook. So it can be concluded that this research area is included in the category of low seismic hazard level

Abstract

Perkembangan sistem autonomus robot mobil atau rover sudah semakin maju. Rover menjadi alternatif dalam berbagai bidang untuk membantu menyelesaikan suatu pekerjaan. Dengan bantuan rover suatu pekerjaan menjadi lebih efisien dan lebih aman. Penelitian ini bertujuan untuk mengendalikan rover secara real time melalui Ground Control Station yang terhubung joystick. Kendali rover menggunaan autopilot pixhawk dengan koneksi bluetooth agar dapat mengirim dan menerima data ke Ground Control Station. Autopilot pixhawk mengendalikan rover dengan cara memberian sinyal PWM ke motor brushless untuk dapat bergerak maju dan mundur, serta sinyal PWM ke servo untuk berjalan lurus, berbelok ke kanan atau ke kiri. Operator Ground Control Station akan memerintahkan rover untuk bergerak menggunakan joystick sebagai pengendalinya. Hasil dari penelitian menunjukkan bahwa joystick dapat dipalikasikan sebagai pengganti Remote RC pada rover sebagai pengendali utama. Dengan mengganti telemtri dengan telemetry berjenis long range atau berbasis internet maka rover dapat dikendalikan dari jarak yang sangat jauh.

Abstract

Physics is a field of study that is least favored by all people. This is because the understanding of physics is only limited to theories and difficult formulas. This research aims to change the paradigm that physics is difficult. There are many applications of physics, one of which is the water rocket experiment. The research activity is carried out by designing the water rocket and then making it. The water rocket is then tested to determine its stability. The finished water rocket product is used for accompanying activities in science laboratory practice. The learning method used in this activity is the field experiment method. The students are involved directly in the practical process.

Abstract

Peralatan laboratorium perlu dilakukan pendataan secara digital agar jumlah dan kondisinya dapat diperbarui dengan cepat. Dengan membuat perangkat lunak inventaris alat dan bahan, dapat digunakan petugas laboratorium sebagai sistem informasi ketersediaan alat dan bahan dalam melayani dosen dan mahasiswa pada saat melakukan praktikum maupun penelitian. Perancangan perangkat lunak dibuat sesuai masukan dari petugas laboratorium. Metode yang di gunakan dalam perancangan software adalah manajemen basis data. Semua alat dan bahan yang dilakukan pendataan dilakukan pemberian kode unik yang kemudian disimpan dalam database. Kode unik digunakan untuk mempermudah pencarian alat dan bahan ketika laboran melakukan pelayanan kepada dosen maupun mahasiswa. Hasil dari perancangan perangkat lunak kemudian dilakukan implementasi dan pengujian sistem untuk mengetahui. Pengujian fungsional perangktat lunak yang selesai dibuat kemudian di tes menggunakan metode blackbox testing. Hasil dari pengujian menunjukkan bahwa software yang dirancang sudah sesuai dengan kebutuhan operator dalam melakukan inventarisasi alat dan bahan yang ada di laboratorium.

Abstract

The Internet of Things (IoT) is no longer a foreign concept. All devices have started to use IoT technology to connect with each other, allowing for remote and real-time monitoring. In this research, portable IoT-based temperature and humidity monitoring was conducted. The research was divided into three stages: hardware design, software design, and device performance testing. The system was designed using an Arduino Mega microcontroller for data acquisition and an ESP32 as a web server to display data from the Arduino Mega. The temperature and humidity sensor used was the DHT21. The RTC DS3231 was used as a timer to facilitate the analysis of the readings. The results of the sensor and RTC readings were displayed on an LCD and web server and stored on a microSD for further analysis. The results of the system testing showed that the system can be used for portable temperature and humidity measurement and real-time monitoring of the readings through a web server from multiple devices simultaneously.

Abstract

A prototype of an automatic tractor control navigation system using a microcontroller has been designed. This study aims to design a prototype of a tractor control navigation system automatically. The design begins with initializing ESP 32, followed by reading GPS (Ublox Neo M8N) and compass (QMC5883L). After that, waiting for commands from the wifi network, followed by reading waypoints, moving the motor, then the motor will drive the tractor prototype. The tests carried out included GPS and compass testing, control response testing, and waypoint navigation testing. The test results show that the accuracy of the coordinates of the GPS UBlox Neo M8N is 0.04 m from the Android smartphone GPS, the QMC5883L compass test shows the difference between the analog compass and the android smartphone compass by 0.4 degrees and 1.0 degrees. Testing the navigation system using the waypoint method, it was found that it was able to map an area or location with a distance of less than 5 meters in following the waypoint route and provide accurate coordinate information to the server during the trip as a source of map information.

Abstract

Energi surya telah dianggap sebagai prospek sumber energi terbarukan untuk pembangkit tenaga listrik. Sistem fotovoltaik surya menjadi objek yang populer untuk dikembangkan oleh peneliti. Rendahnya efisiensi dalam konversi energi adalah salah satu kelemahan sistem ini. Modul fotovoltaik memiliki titik operasi tunggal di mana output tegangan dan arus menghasilkan output daya maksimum. Dalam kebanyakan sistem fotovoltaik, algoritma kontrol tertentu, yaitu Maximum Power Point Tracker (MPPT) untuk memanfaatkan secara maksimal energi surya tersebut. Ada tiga metode utama pada MPPT yaitu metode konvensional, metode kecerdasan buatan, dan metode hibrid. Setiap metode memiliki kelebihan dan juga kekurangan. Metode konvensional memiliki kelebihan seperti biaya rendah dan implementasi yang sederhana tetapi juga memiliki kerugian seperti tidak dapat beradaptasi dengan kondisi lingkungan. Metode berdasarkan kecerdasan buatan memiliki Power Point Tracking yang lebih cepat dan koreksi terhadap kondisi lingkungan sebagai kelebihannya tetapi juga memiliki kerugian seperti penerapan yang lebih rumit dan biaya yang lebih mahal.
