Abstract

Kindergarten (TK) is the very important phase in child education to develop the next generation of the nation. Therefore, kindergarten teachers play an important role in the student learning. Kindergarten teachers should not only excel in conventional learning, but also in innovative learning, starting with blending Information Technology in student learning process. The purpose of the Community Partnership Program (PKM) is to improve the human resource quality in the implementation of Information Technology in administration and student learning process. The skill improvement focuses on the training of Google Applications such as Google Docs, Google Form, Google Slide, Google Sheet, and social media as well as Blogger to publish school's updated information to public.The consideration of partnering with TK Bina Anaprasa is because of the lower accreditation in C rank for over 23 years of establishment, and the lower understanding in Google and Internet application. In addition, the school do not have social media like blog or web to share information with the public. Therefore, in the short term the PKM program can improve the teachers' skills in area of Information Technology and in the long term the PKM program can establish an Internet-based kindergarten.

Abstract

The tourism sector has been growing rapidly along with the decline of COVID-19. This sector should pay attention to safety and security, which is by tracking the position of tourists. In this work, we propose a tourist positioning tracking system. A node containing a microcontroller with LoRa wireless communication called unknown node (UN) is assembled as a wearable device. We use the received signal strength indicator (RSSI)-based localization technique with an additional normalization method to correct the error rate in position estimation. This method estimates the distance between the anchor node (AN) and UN to approximate the actual distance value. Three-dimensional position tracking (longitude, latitude, altitude) of five UN surrounded by four AN was performed using the quadlateration method. The estimation process was carried out by the UN whereas receiving information is transmitted from the four AN. The communication between AN and UN used a scheduling algorithm on all AN. The position estimation error of the five UNs was measured using mean square error (MSE) yields 20.73 m, 50.32 m, 32.92 m, 21.40 m, and 16.89 m respectively. The accuracy of the estimated distance obtained by the proposed normalization quadlateration method is increased up to 15.22%.

Abstract

Perangkat Internet of Things (IoT) merupakan perangkat yang terkoneksi pada jaringan internet. Salah satu media transmisi yang low power berbasis IoT adalah LoRaWAN.  LoRaWAN mampu menerima data dari banyak user pada jarak jauh dan terkoneksi langsung dengan database server melalui internet.  Pada artikel ini, membahas mengenai monitoring posisi multi node pada jaringan LoRaWAN. Terdapat tiga node, direpresentasikan sebagai end node. LoRaWAN sebagai satu node server atau disebut LoRa Gateway. Pada node server terpasang aplikasi berbasis Graphic User Interface (GUI) yang dapat memantau posisi end node secara real time. Pengujian pada artikel ini, meliputi pengujian transmisi packet loss dari end node ke node server, dan pengujian aplikasi untuk memenuhi Human Computer Interaction (HCI). Hasil transmisi tiga node end ke LoRa Gateway berturut-turut adalah 6,04%, 1,13%, dan 1,9%.  Pengujian kelayakan aplikasi dari segi sudut pandang pengguna telah memenuhi standart HCI dengan nilai sangat setuju 61% dan setuju 50%.
