Abstract

The background of this research is the oyster mushroom cultivation process where people often have difficulty regulating temperature and humidity because these values change frequently, so people often have to monitor where the mushrooms grow to check the temperature and humidity. The purpose of this research is to make it easier for oyster mushroom farmers to monitor and control normalizing temperature and humidity by means of automatic watering and wider ventilation openings, this is done via the website by sending data from NodeMCU to a realtime database. The results of the research conducted show that the steam pump will automatically turn on if the DHT11 sensor detects a temperature of 28ºC or 60% humidity. The pump will automatically stop watering when the normal temperature is 22ºC-28ºC or humidity is 60%-70%. Vents will automatically open when the temperature is 22ºC or humidity is 70%. The vents will remain closed when the temperature is 22ºC or 60% humidity. Apart from watering, this system can also monitor the temperature and humidity status of the kumbung in real time through the website by sending data via firebase.

Abstract

Long Range (LoRa) is a wireless communication technology using Chirp Spread Spectrum (CSS) that allows for sending low-power long-distance data via the ISM (Instrumentation Science and Medical) band. This study aims to utilize LoRa technology with a Master Slave communication model combined with a Wireless Sensor Network (WSN). The devices used in this study are LoRa, ESP32 and MQ135 sensors. The MQ135 sensor functions to measure ambient air quality. Then data from the sensor is sent using the LoRa module via 3 nodes to the master node. The OLED display is used to display the results of sensor readings in the form of CO and CO2 values. Then ESP 32 functions to process data from the sensor and regulate system performance. The air quality detection system was tested under two different conditions, areas with and without obstacles. Areas with obstacles is located on Campus 1 PNUP. Areas without obstacles is located on Mandai Underpass. The results of the tool test show that the area with obstacles located at Campus 1 PNUP, the furthest distance that can still be reached by LoRa is 100 meters. For the second location of the Mandai Underpass, the furthest distance LoRa still communicates is 140 meters.

Abstract

The Garassik Micro-Hydro Power Plant in Panassang Village, Enrekang Regency, with an installed capacity of 3.7 kW, experiences an energy deficit due to the community's electricity demand of 390.74 kWh per day. Despite its efficient operation, the plant generates a maximum of only 88.8 kWh per day, underscoring the need for capacity enhancement. This study explores the potential of utilizing turbine wastewater as an energy source by designing a Multi Powerhouse (MPH) Micro-Hydro Power Plant to optimize water energy usage. The proposed MPH system evaluates water energy potential, determines optimal powerhouse placements for effective head height, and calculates total power output. Unlike the single-powerhouse model, the MPH system addresses water flow limitations, particularly during periods of reduced flow, significantly improving total power output to 160.235 kW, a 171% increase. Key advantages of the MPH model include better utilization of turbine wastewater, enhanced operational flexibility, and improved water energy efficiency. Using a descriptive quantitative research method, this study begins with a location survey to collect turbine wastewater characteristics, followed by mathematical modeling for analysis. Results reveal output flow rates of 0.189 m³/s, 0.187 m³/s, and 0.185 m³/s across three powerhouses, with effective head heights of 24.782 m, 29.725 m, and 34.729 m, respectively. The system uses Crossflow turbines, ideal for medium heads and moderate flow rates. Economic analysis indicates an NPV of IDR 2.400.000.000,- an IRR of 14%, and a BCR of 2.5, with a payback period of 5.45 years, making the project financially viable and sustainable.

Abstract

Edge detection is a fundamental technique in digital image processing, crucial for identifying object boundaries. However, detecting edges in low-intensity and noisy images remains a significant challenge. This study proposes an optimal edge detection method by integrating the Canny algorithm, Contrast Limited Adaptive Histogram Equalization (CLAHE), and Perona-Malik Diffusion Filter, with automatic kappa (k) value determination using the Fractional Order Sobel Mask. The process begins with noise reduction through the Perona-Malik Diffusion Filter, followed by local contrast enhancement using CLAHE, and concludes with edge detection via the Canny algorithm. Experimental results demonstrate that the proposed method significantly enhances edge clarity and robustness against noise compared to the conventional Canny algorithm, particularly for low-intensity images and images with noise. Tests on leaf and medical images confirm the effectiveness of this method in improving edge detection quality in digital images.

Abstract

This study analyzes the distribution of the magnetic field outside a solenoid using an experimental and theoretical approach with the Hall effect sensor SS49E, amplified by the IC LM358. Measurements were conducted in three dimensions to characterize the magnetic field along the solenoid. The experimental results indicate that the magnetic field distribution is non-uniform, with the highest intensity near the solenoid's ends and a minimum value at its center. Empirical data were compared with a theoretical model based on Biot-Savart’s law, showing a 98% correlation, which indicates the accuracy of the measurement method used. This research provides additional insights into the magnetic field outside solenoids and it can be an excellent school project for undergraduate students.
