Abstract

Electricity costs in boarding rooms are often unfairly distributed because each room is charged the same amount, even though electricity usage varies. To solve this problem, a system was created to monitor each room's power usage more efficiently using Long Range (LoRa) technology. This system uses an ESP32 microcontroller, a PZEM-004T sensor, and LoRa, programmed with Arduino IDE. The sensor collects power usage data and sends it to the boarding house owner over the LoRa network, with accuracy close to 99% in three tests. The data is transmitted up to 150 meters with an RSSI of -107 dBm in non-line-of-sight (NONLOS) conditions and up to 600 meters with an RSSI of -111 dBm in line-of-sight (LOS) conditions. It is also connected to an Android app for easier power management and monitoring.

Abstract

Kampung Setaman, which is located in Kelurahan Ratujaya, is an area where the majority of the people are Micro, Small and Medium Enterprises (MSMEs). Internet access is an important aspect for people to sell their products. In this community service activity, Politeknik Negeri Jakarta (PNJ) Telecommunication Study Group (KBK) carried out internet installation and coverage area expansion using a microstrip antenna. This aims to ensure that people can enjoy internet access in a wide area without requiring the installation of many access points. There are two installation points, namely Posyandu Kartini 2 and Jami Al-Huda Mosque. The microstrip antenna is made in the form of a 1x4 square patch. From the measurement results, by using the created antenna the access point can reach a distance of up to 115 m with Line of Sight (LOS) conditions. As a result of the installation, people can enjoy free internet access in a wide area.

Abstract

As a natural resource, air plays a vital role in sustaining life. Clean air provides significant benefits to living things, while polluted air can disrupt the balance of the ecosystem. Sources of air pollution include motor vehicle exhaust, fossil fuel-based industrial activities, and forest fires. Maintaining clean air quality requires an air quality monitoring device. With the development of Internet of Things (IoT) technology, this study designed a portable IoT-based air quality monitoring device using a GPS module, MQ-2, MQ-135, MQ-136 sensors, and an LTE module. This device is designed to be easily carried to various locations. The GPS module is used to obtain precise location data, while the integrated air quality sensor will measure parameters such as particulate concentration, toxic gases, and air humidity. The data displayed on the air quality monitoring device are CO, CO2, SO2 values, and location coordinates. The received air quality data complies with the ISPU (Air Pollution Standards Index) standard. Test results show that the sensor can read measurement values ​​with air quality categories of "Good," "Moderate," and "Unhealthy." The Android application can also display test data sent from the Firebase real-time database to the Android application for CO, CO2, SO2, Longitude, Latitude, time, and date.

Abstract

Patrolling is a proactive activity carried out by moving from one place to another, checking and ensuring area security and order. This is necessary because security officers cannot directly observe the areas they handle. To make patrols more efficient, a building guard patrol monitoring system is needed. The patrol officer's equipment is brought closer to the RFID tags in each room. The LoRa Node in the patrol tool then sends data to Firebase via LoRa Gateway in the form of room name, patrol officer's name, username, time, date and status. Then, the Android application will display data on patrol officers' tapping activity in real-time to prevent fraud while on patrol. The LoRa test results using the LOS (Line of Sight) method reached a maximum distance of 900 m and Non-LOS reached a maximum distance of 200 m. Internet connection on Android applications use VSAT. The average QoS parameter results for the VSAT internet network for throughput are 28.88 KB, packet loss is 0%, and delay is 467,697 ms.
