Abstract

This activity describes the planning, installation, and evaluation of the implementation of a Solar Power Generation System (PLTS) at the Istiqomah Community Reading Park, Terjun Village, Medan Marelan District. The objectives of the activity are (1) to provide a reliable independent power supply for lighting and auxiliary learning devices at the reading park, (2) to increase the managers’ capabilities in operating and maintaining the PLTS, and (3) to assess the technical and social sustainability impacts after installation. Methods used include an energy needs and peak load survey, design of an off-grid system based on the survey results, installation of main components (PV panels, controller, batteries, inverter), and operational and maintenance training for the reading park managers. Evaluation was conducted through measurements of energy availability (hours of lighting operation), reduction in consumption from the PLN grid (kWh), and user satisfaction questionnaires. Based on the needs survey, the reading park’s electricity use is mostly allocated to lighting, fans, and computer operation. Results show that the installed PLTS successfully supplied 95% of the reading park’s daily electricity needs, directly resulting in monthly electricity savings of up to Rp 250.000,00. The results indicate that the designed PLTS meets lighting and light electronic device needs during the reading park’s operating hours, reduces dependence on external supply, and increases community participation in literacy activities, making it an effective strategy for achieving energy independence.

Abstract

The rapid growth of Internet of Things (IoT) technology has increased the demand for flexible and user-friendly wireless connectivity in embedded systems. One of the most widely used modules in IoT applications is the ESP8266, which integrates a microcontroller and WiFi capability in a compact and low-cost platform. Despite its advantages, WiFi configuration on the ESP8266 is commonly implemented using static credentials that are hardcoded into the firmware. This approach requires recompilation and reprogramming whenever network parameters change, making it inefficient and impractical for end users and large-scale deployment. This research proposes the design and implementation of a WiFi Manager system on the ESP8266 module to enable dynamic WiFi configuration without modifying the firmware. The proposed system allows the ESP8266 to automatically switch to Access Point (AP) mode when it fails to connect to a previously stored network. Users can then configure WiFi credentials through a web-based interface using a standard web browser. The configuration data are stored in non-volatile memory and used to reconnect the device in Station (STA) mode once a valid network is detected. The research methodology includes system design, firmware development using the Arduino platform, and functional testing to evaluate connectivity performance and reliability. Experimental results show that the WiFi Manager system successfully simplifies the WiFi configuration process, achieves a high connection success rate, and provides stable reconnection after power reset. The proposed approach enhances usability, deployment flexibility, and scalability of ESP8266-based IoT devices.

Abstract

Current advances in knowledge and technology are driving people to think creatively. Similarly, the use of automation technology has advanced to the point where it can automate many daily activities. When automation is implemented on an ongoing basis, it can be leveraged to assist with routine tasks (Tullah et al., 2019). One of the most pressing applications of automation technology today is in the implementation of security systems. Security is essential everywhere and at all times—whether at home, at work, during daily activities, or while resting. One place that requires security is the home, which serves as a storage place for valuables; threats typically come from outside sources such as thieves and scammers (Apsari & Prapanca, 2018). This study aims to design and build a prototype of an IoT-based smart home security system using four different sensors, with the ESP32 serving as the system’s central processor, to effectively detect and respond to security threats. This system offers various benefits, such as enhanced security through accurate threat detection, rapid notifications regarding unwanted security incidents, improved well-being for residents, and the ability to monitor the home in real-time remotely via a smartphone app. The sensors used include a PIR sensor for motion detection, an MQ2 sensor for gas leak detection, an SW-420 sensor for earthquake vibration detection, and a GY-906 sensor for burning temperature detection. To enhance its mobility, the system is designed so that the overall performance of the sensors can be monitored using the Blynk app. This research consists of four stages: data collection, rapid prototyping, prototype design, and prototype testing.

Abstract

This research aims to design and build a prototype of an automatic nutrient irrigation system for hydroponic lettuce plants using the drip method based on ESP32 and the Internet of Things (IoT) using the Blynk platform. The system monitors pH, Total Dissolved Solids (TDS), temperature, humidity, water level, and nutrient flow volume using a 4502C pH sensor, a TDS Meter V1.0 sensor, a DHT11 sensor, an HC-SR04 ultrasonic sensor, and a YF-S201 water flow sensor. The system also utilizes a DS3231 RTC module as an accurate time reference. Nutrient irrigation is carried out automatically at a volume of 340 mL per cycle based on a time schedule. The system is designed to monitor pH (6–7), nutrient concentration (TDS) (560–840 ppm), and solution capacity in the reservoir (>20%). When parameters fall outside the specified limits, the system will trigger an alarm via a buzzer and send real-time notifications to the user via the Blynk platform. The DHT11 sensor is used to classify environmental conditions so that watering intervals can be adjusted adaptively. Furthermore, the system utilizes the Non-Volatile Storage (NVS) feature on the ESP32 to store the last watering data to maintain system consistency after a power outage or restart. The system also features a push button as a reset button to re-initialize the system. Test results show that the pH, TDS, and ultrasonic sensors have error rates of 0.65%, 1.48%, and 0.83%, respectively. The system is capable of precisely controlling watering volume using the YF-S201 water flow sensor. The system can still operate optimally offline without relying on an internet connection. Thus, the developed system can improve the efficiency, accuracy, and reliability of drip hydroponic lettuce nutrient irrigation.

Abstract

The rapid development of robotics technology drives the need for efficient automation systems, particularly in the industrial and educational sectors. One widely developed implementation is the robotic arm that can mimic human movements to manipulate objects with precision. This research aims to design and build a robotic arm prototype based on an Arduino microcontroller with four servo motors as the main actuators. The methods used include stages of information gathering, system requirements analysis, mechanical and electronic design, hardware construction, programming using the Arduino IDE, and system testing. The research results show that a robotic arm system with four degrees of freedom (4 DOF) is capable of performing basic movements such as picking up, lifting, and moving objects quite well. The integration between mechanical systems, electronics, and software works optimally, with the microcontroller able to controlling the movement of the servo in a coordinated manner. The robot can also be operated in manual mode using a joystick or in automatic mode based on predetermined parameters. Tests show that the robot is able to lift loads up to 350 grams optimally, but experiences limitations with larger loads. The implication of this research is that the designed system can be used as an effective learning medium for understanding basic robotics concepts, particularly related to actuators, control systems, and system integration.

Abstract

Water quality is an important factor that affects human health, the environment, and various sectors of life. However, conventional water quality monitoring methods still have limitations, such as requiring a long time, high costs, and being unable to provide real-time data. This study aims to design a Smart Water Quality Monitoring System based on the ESP32 microcontroller capable of monitoring water quality automatically and continuously. The system uses several key parameters, namely pH, temperature, turbidity, and Total Dissolved Solids (TDS), which at the design stage are simulated using a potentiometer. Data from the sensors is processed by the ESP32 through an analogue-to-digital conversion process, then displayed in real-time on a 16×2 LCD and potentially sent to an Internet of Things (IoT) based platform. The design results indicate that the system is able to read and display data accurately according to input changes, and operates according to the designed algorithm. This system has advantages in terms of efficiency, ease of development, as well as multi-parameter monitoring capability. Thus, the designed system can serve as an alternative solution for more effective water quality monitoring and has the potential to be developed into an IoT-based remote monitoring system.

Abstract

Conventional lighting systems in green open spaces, such as city parks and residential gardens, predominantly rely on manual controls or static timers. This conventional approach often leads to significant electrical energy waste, as the lights continuously operate at maximum intensity regardless of the presence of visitors or activity in the area. In addition, the increasingly urgent issue of environmental pollution necessitates the availability of microclimate monitoring data that the public can easily access prior to engaging in outdoor activities. This research aims to design and implement an Internet of Things (IoT)-based Smart Integrated Garden Light prototype as an intelligent solution that integrates energy efficiency with an environmental monitoring station. The prototype utilizes the ESP32 DevKit V1 microcontroller as the central processing unit, interfaced with four primary sensors: a Light Dependent Resistor (LDR) to detect day and night ambient lighting conditions, a Passive Infrared (PIR) sensor to detect visitor movements, a DHT11 sensor for temperature and humidity monitoring, and an MQ-135 sensor to detect fluctuations in harmful gases (air quality). The methodology employed includes literature review, hardware and software design using a multitasking approach in the Arduino IDE, physical assembly, and functional testing scenarios. Through this design, the system is expected to significantly reduce energy consumption by implementing an adaptive lighting mechanism (dimming), wherein the light will operate in a dim state (standby mode) when the park is empty at night, and automatically switch to full brightness upon detecting visitor presence. Furthermore, the system is designed to transmit microclimate parameter data continuously and in real-time to a cloud platform via the Blynk application, allowing users to transparently access environmental information using a smartphone. It is concluded that this innovation has the potential to transform garden lamp posts from mere conventional lighting devices into intelligent infrastructures (smart nodes) that support security, energy efficiency, and a sustainable Smart City concept

Abstract

Operational reliability in the modern manufacturing sector is highly dependent on the performance of induction motors as the main drive [1]. This dependency poses a significant risk if maintenance is still reactive, as sudden failures can trigger significant financial losses. As a solution, the MachinaSense Predictive Engine Guardian system is designed using ESP32-based Internet of Things (IoT) technology to continuously monitor machine conditions [2]. This system integrates four critical sensor parameters to detect anomalies early. [3]. Meanwhile, the vibration sensor plays a role in detecting mechanical disturbances such as bearing wear through vibration frequency analysis [5]. To prevent insulation damage due to heat, a temperature sensor is used to monitor the condition of the stator [4], while the rotational speed is monitored through an RPM monitoring system to analyze the motor slip value according to the fundamental theory of electrical machines [6]. All sensor data is acquired using I2C and UART communication protocols and then sent to a cloud platform via a WiFi network [4]. This multi-sensor integration has been proven to be able to identify operational deviations before they exceed critical thresholds, thus providing a much more accurate diagnosis than single-sensor methods. The application of this technology not only minimizes downtime, but also becomes a concrete step in the transformation towards Industry 4.0 which prioritizes data-based predictive maintenance [7].
