The existing antenna has undergone many modifications to obtain several parameters to achieve the desired function. In this research, the dimensions and design of a coaxial-fed microstrip antenna were calculated and worked at a frequency of 2.4 GHz. The purpose of this study was to see the effect of the truncated corner on the bandwidth and return loss of the 2.4 GHz microstrip antenna. An experimental approach was taken to see antenna optimization by adding a truncated corner to increase the bandwidth of the antenna. The addition of a truncated corner using the parameter sweep technique for a truncated corner (ptc) coefficient from 0 to 6 was carried out to see the effect on the bandwidth, return loss, and working frequency of the antenna. The results showed that the addition of a truncated corner affected bandwidth where the bandwidth increased to a certain value of 1.3 MHz. In addition, there is also a shift in the working frequency of the antenna to a higher and lower frequency followed by a change in the value of the return loss obtained. Keywords: Truncated Corner, Bandwidth, Return Loss, dan Microstrip.

Abstract

This study developed and evaluated an integrated Internet of Things (IoT)-based access control system that unifies residential gate operation, garage door automation, and garage lighting within a single platform. Conventional home automation deployments typically address only one function at a time, resulting in fragmented control and limited interaction between subsystems. Compared to prior smart home implementations that focus on single subsystems, the proposed platform jointly manages gate, garage door, and lighting and reports scenario-based reliability metrics. To address this gap, the proposed system used an ESP32 microcontroller as the central controller, ultrasonic distance sensors for vehicle detection, servo motors for mechanical actuation, and a relay module for lighting control. A mobile application built with the Blynk platform provided real-time monitoring and remote control via smartphone. The prototype was tested under three scenarios-manual mobile control, fully automatic sensor-triggered operation, and combined operation-with 20 repeated cycles per scenario. Performance metrics included servo actuation time, communication latency between the mobile application and the ESP32, sensor accuracy, and operational reliability. The gate and garage door achieved opening times of approximately 1.0-1.2 s and 1.5 s, respectively, while end-to-end communication latency remained between 300 ms and 480 ms across all tests. Ultrasonic distance measurements showed a maximum error of 1.8 cm and an average error below 1.2 cm, with no system failures in any scenario. These results demonstrate that the integrated design is technically feasible, reliable, and suitable as a cost-effective foundation for residential access control.  Future work will focus on scaling the prototype toward full-size installations and extending integration with additional smart home services.

Abstract

Environmental problems caused by suboptimal waste management have become a major issue in Nagari Batu Basa, particularly the habit of residents disposing of waste into rivers. This condition worsens during the dry season, as waste accumulation generates unpleasant odors and poses health risks, especially from plastic waste that is difficult to decompose and has even contributed to malaria cases among some community members. This community service activity aims to increase public awareness of integrated plastic waste management and to discourage residents from disposing of waste into rivers. The methods employed consist of four approaches. The first approach involves the provision of educational waste posts as an initial effort to prevent indiscriminate waste disposal. The second approach is the construction of an integrated plastic waste collection facility at the nagari office, equipped with dry waste sorting facilities. In addition, the community was provided with training on ecobrick production, which could be exchanged for incentives. The fourth approach applies a door-to-door collection method through the involvement of KKN students from Universitas Negeri Padang (UNP), who collected waste that had been gathered by the community from shops, schools, and mosques. The results of the community service activities indicate positive community engagement, as evidenced by the successful production of 300 ecobricks by the community in collaboration with KKN UNP students, of which 260 were branded as Nagari Batu Basa ecobricks. This activity contributes significantly to building community awareness of household-level waste segregation and supports the creation of a healthier and more sustainable nagari environment.
