Abstract

This Long Range communication technology is widely used as a substitute for LTE communication tools, but sending text, images, and voice in Long Range communication has a different performance ratio of transmission time speed. This tool uses two TTGO ESP32 LoRa modules, the tools used to design the application using the MIT App Invertor and an additional device, a USB OTG cable. The way this tool works is to send text, image and voice messages without using a server but using point-to-point communication between two devices. The test results of sending text, images, and voice on Long Range communications that have been carried out in data loss testing conditions, show that the results of sending text messages, the farther the distance, the delivery speed is relatively stable with a delay of 1.2 seconds, while for sending images the delay results are getting bigger which is 3.9 seconds and for voice transmission it is not very compatible because LoRa devices can only send 256 bytes of data packets.   Keywords: Pesan Teks, Gambar, Suara, App Inventor, TTGO ESP32 LoRa.

Abstract

In the digital era, information boards have migrated from conventional forms to digital forms, hence the term digital signage. Digital signage is a digital device that has been programmed to display information through a monitor board, LCD TV, PLASMA TV, projectors, and digital billboards. Currently, it is very common for us to pay attention to an information board in offices, in lecture buildings, at airports, and train stations in the form of a flat screen monitor controlled by a computer. Among them, the media can only be placed in one place and it is relatively difficult to move. Therefore, the use of computers will be replaced by using raspberry pi as the operating medium. This research includes raspberry pi, RGB LED as a screen to display information and the web to change data or information displayed on the RGB LED screen. Based on the research conducted, it was found that data in the form of images or videos can be displayed on the RGB LED screen using the web.

Abstract

Lo-Ra (Long Range) is a process of changing a certain periodic wave so that it becomes a signal capable of carrying information. LoRa technology offers a very attractive long term. Such as using low power and data transfer that is guaranteed security. Public networks that use LoRa networks will be able to provide a wider signal coverage. Compared to cellular networks in general, LoRa is a network that covers a wider range. Besides that, it is also easy to fit into the needs we need. This need is like any other electronic device that uses wireless installation. The making of this tool is a fire detector to reduce the impact of forest fires and has advantages over other tools, namely that many fire detection tools used do not meet criteria such as sending information that cannot reach long distances so that a tool that can solve this problem appears, namely Long Range ( LoRa), LoRa can anticipate lost GSM signal coverage. The purpose of this research is to detect and monitor the level of vulnerability to fire and provide information to officers in real time which will be displayed on the blynk. The results of this study obtained that this tool is able to detect forest fires up to a distance of 700 meters, if it exceeds that distance the reading will be error, this tool detects forest fires by reading the three sensors, if the three sensors have reached the threshold point, namely with a temperature sensor greater than 40 degrees Celsius, the humidity sensor value is less than 61%, and the smoke sensor value exceeds 2670 ppm, the tool will give a fire warning that will appear on the Blynk notification. at a distance of up to 700 m, the average delay for node 1 reaches 23.2 seconds and the average delay for node 2 reaches 54.5 seconds. And it can also be seen that the average percentage of temperature error obtained at node 1 reaches 4%, and the average error in humidity for node 1 reaches 6.4%, then the average percentage error temperature obtained at node 2 reaches 8.5%, and the average error at node 2 humidity reaches 18%.

Abstract

SMAS IT Mutiara adalah salah satu sekolah menengah yang ada di kota kecamatan pinggir kabupaten Bengkalis. Materi pelajaran yang diberikan pada sekolah ini seperti pada umumnya disekolah-sekolah SMA pada umumnya, yaitu materi Pendidikan formal sesuai dengan yang ada dikurikulum yang ditetapkan oleh pemerintah. Padahal banyak siswa yang terpaksa tidak melanjutkan ke tingkat Pendidikan yang lebih tinggi dan harus langsung bekerja setelah lulus. Kondisi inilah yang menyebabkan dibutuhkannya pengetahuan dan skill tambahan untuk bekal siswa-siswa tersebut setelah lulus. Skill-skill yang berkaitan dengan Teknologi Rekayasa Jaringan Telekomunikasi yang salah satunya berkaitan dengan Teknologi IoT teknologi yang saat ini sedang berkembang sangat penting untuk mereka kuasai. Berdasarkan latar belakang tersebut maka tim PkM dari Politeknik Caltex riau berinisiatif memberikan skill tambahan kepada siswa SMA tersebut sehingga memiliki bekal kemampuan lain disamping kemampuan akademik yang mereka terima di sekolah. Tim PkM telah memberikan pengetahuan berbentuk workshop pembuatan modul aplikasi IoT dengan diikuti oleh 23 Peserta. Dari hasil survey yang telah disebar ke peserta terkait workshop ini memberikan manfaat bagi peserta dengan persentase yang ditampilkan sebesar 100%. Terkait dengan keberlanjutan manfaat peserta menilai dirange baik sampai sangat baik yaitu 90-95%. Untuk penjelasan materi tersampaikan dengan baik, dengan nilai 100%. Sementara untuk pelaksanaan kegiatan secara keseluruhan, tingkat kepuasan peserta berada adalah 97,85%.

Abstract

The data from Badan Pusat Statistik Provinsi Riau in 2020 indicates that Riau Province is poised to benefit from a demographic bonus, with its population predominantly composed of the younger, productive generation. The abundance of young individuals is anticipated to serve as a driving force in enhancing the quality of life for the surrounding communities. The Riau Youth Leader Club (RiyoLC) is an empowerment program aimed at organizing and implementing community empowerment initiatives within Riau. RiyoLC is envisioned as a platform for Riau's youth to exchange ideas, information, and best practices, empowering them to address local challenges and contribute to the advancement of Riau Province. PT Pertamina Hulu Rokan (PT. PHR) has collaborated with Politeknik Caltex Riau to conduct various capacity-building activities, program development support, and implementation assistance for 34 participants from different regencies and cities within PT. PHR WK Rokan's operational area. The program covered topics such as leadership, problem-solving, critical thinking, project management, communication techniques, and presentation skills. As a result, seven community program proposals have been generated, with three of them receiving implementation support from PT PHR
