The Design of an Integrated IoT and Artificial Intelligence System for Fish Quality Degradation Diagnosis
type: item
description: In post-harvest handling, fish quality assessment is typically carried out using traditional sensory observations, which are potentially resulting in inconsistent diagnoses. Furthermore, prior research has not fully integrated the Internet of Things (IoT) with artificial intelligence for fish quality diagnostics, and it frequently concentrates on a single quality metric. This study aims to design and evaluate an integrated system based on IoT and artificial intelligence using a Case-Based Reasoning (CBR) approach for diagnosing fish quality degradation. The developed system utilizes IoT-based sensors to monitor physicochemical parameters, such as temperature, pH, and gas indicators, with real-time data transmission to a cloud platform. The collected data are analyzed using a CBR model as a decision support system. Performance evaluation was conducted using 120 testing data under controlled storage conditions and validated through expert assessment. The results show that the system achieves a diagnostic accuracy of 92.5%, with precision of 91.8%, recall of 93.2%, and an F1-score of 92.5%. In addition, the system has an average data transmission latency of 0.87 seconds, enabling near real-time diagnosis. These findings indicate that the system provides accurate and efficient diagnosis of fish quality degradation and supports post-harvest quality management

Analysis of New Students' Science Process Skills Readiness and Its Impact on Basic Physics Learning Outcomes 1
type: item
description: Mastery of science process skills (SPS) is a key foundation in physics education at the university level for building conceptual understanding and scientific thinking skills. Although crucial, first-year students generally have very heterogeneous practical skills due to their diverse educational backgrounds. This study aims to investigate the correlation between SPS and the learning outcomes of the 2024 cohort of students in the Basic Physics 1 course in the Physics Education Study Program at UIN Ar-Raniry Banda Aceh. This study used a quantitative correlational design with purposive sampling techniques on 20 students. Data were collected through the SPS test instrument and documentation of final course grades. Data analysis was performed using Spearman's Rho correlation test, considering that the data were not normally distributed based on the Shapiro Wilk test results. The results showed a significant relationship between KPS and learning outcomes with a correlation coefficient of 0.431 (ρ=0.029) which is classified as moderately strong. An interesting finding in this study highlights the very high gap in SPS mastery among new students, which is inversely proportional to their relatively homogeneous academic achievements. This phenomenon indicates an imbalance between psychomotor competencies in practical work and students' cognitive achievements. Based on these findings, standardizing and strengthening practice-based learning at the beginning of the lecture period is a strategic step needed to minimize the gap in student abilities and improve the quality of physics education comprehensively.

Simulation of Fuzzy Logic Implementation in an IoT-Enabled Water Quality Monitoring System Using ESP8266
type: item
description: This paper presents the design and implementation of a fuzzy logic-based water quality monitoring system using the ESP8266 microcontroller and a set of environmental sensors. The system utilizes temperature, humidity, pH, and Total Dissolved Solids (TDS) as input parameters to assess water quality in real time. Each input is fuzzified into linguistic categories and processed through a fuzzy inference engine to produce a continuous water quality score aligned with WHO standards. The system is integrated with an IoT platform for remote monitoring. Simulation results demonstrate smooth transitions between membership functions and the model’s ability to handle overlapping conditions. For instance, at pH 7.5, the system outputs membership degrees of 0.83 in the "Good" set and 0.17 in the "Moderate" set, reflecting a chemically acceptable state. With sensor inputs of 28°C temperature, 65% humidity, pH 7.5, and 400 mg/L TDS, the system produces a water quality score of 12.6, indicating excellent quality. Field testing under various conditions and comparison with laboratory measurements show an accuracy of 92%. The fuzzy logic model offers more consistent classification than crisp thresholding, especially during transient changes or sensor drift. However, system accuracy heavily depends on proper sensor calibration, and the rule base must be adapted to regional standards. Additionally, real-time fuzzy computation on the ESP8266 is limited, requiring processing to be offloaded to MATLAB or cloud-based systems.

The Design of a Turbine Emulator for a Pico-Hydrokinetic Power Generation System
type: item
description: Pico-Hydrokinetic Power Plants (PHKPP) utilize the kinetic energy of flowing water as a sustainable alternative to fossil-based energy. However, higher education remains largely theoretical due to limited laboratory facilities, restricted access, and inadequate simulation tools. This study develops a cost-effective PHKPP emulator to support experiential learning and represent real-world operating conditions. A quantitative approach is used, integrating the ADDIE model with experimental testing. The emulator consists of two independent units that simulate a turbine using a three-phase induction motor controlled by Variable Speed ​​Drives (VDRs), while power generation is achieved through a single-phase induction generator. Evaluation results indicate that the emulator effectively supports learning, enabling analysis of turbine performance, control strategies, and energy conversion efficiency. Student responses demonstrated a high level of acceptance, with an average score of 4.43 across all aspects of functionality, usability, relevance, and design. These findings confirm that the emulator effectively enhances conceptual understanding and is an appropriate learning solution for PHKPP learning

IoT-Based Real-Time Monitoring and Control of Well Water Filtration
type: item
description: Controlling a well water filtration system via the internet is a modern solution in the industry 4.0 era to ensure optimal filter performance. This study aims to develop an IoT-based system to monitor and control well water filtration by measuring inlet and outlet pressures. The system uses two pressure sensors, one turbidity sensor, and five solenoid valves to regulate the filtration, backwashing, and rinsing processes. All components are integrated with a NodeMCU ESP32 microcontroller. The IoT user interface was developed using the Blynk application on an Android smartphone, which allows real-time monitoring and automatic notification when filter performance decreases. Experimental trials were conducted by gradually injecting turbid water with varying turbidity levels (low, medium, high) into the filter. The results showed that filter clogging caused an increase in inlet pressure and a decrease in outlet pressure. The backwashing and rinsing processes can be activated via a smartphone when the inlet pressure increases by 24%–45% and the outlet pressure decreases by 37%–72%. The turbidity of the filtered water remained within the range of 0.14–0.19 NTU, which is still below environmental health standards. This demonstrates that the developed IoT-based filtration system is effective for real-time monitoring and control of well water quality.

description: This study aims to design and test a three-phase induction motor speed measurement device based on Arduino Uno. Three-phase induction motors are often used in industry because of their reliability, high efficiency, and easy maintenance. However, these motors have weaknesses, namely low starting torque and difficulty in regulating speed, which can cause operational instability. Therefore, this study developed an Arduino Uno-based control system capable of regulating motor speed by changing the frequency of the electrical supply. This research is quantitative in nature and uses an experimental method. The results of the study show that the designed device is capable of improving the stability and operational efficiency of three-phase induction motors. The use of an LM393 speed sensor aligned with the motor rotor allows the system to respond to load changes in real-time, maintain a constant speed, and reduce energy consumption. Based on these results, it can be concluded that the development of an Arduino Uno-based speed measurement device is effective in addressing the challenges of controlling the speed of a three-phase induction motor and has broad application potential in industry.

A Motorcycle Security System Based on Rfid Technology Using the Indonesian Electronic Identity Card (E-KTP) as an Ignition Key
type: item
description: Motorcycle theft is one of the most frequent criminal acts in Indonesia and is closely related to the limitations of conventional vehicle security systems in preventing unauthorized access. This study proposes the design and implementation of a motorcycle security system based on Radio Frequency Identification (RFID) technology that utilizes the Indonesian electronic identity card (e‑KTP) as an ignition key. The research employs a Research and Development (R&D) approach with the ADDIE model—Analysis, Design, Development, Implementation, and Evaluation—to ensure a systematic and iterative development process. The proposed system consists of an RFID RC522 module, Arduino Uno microcontroller, relay‑based ignition switching, and an LM2596 step‑down DC–DC power regulator. Experimental testing shows a 100% authentication success rate for registered e‑KTP cards, with an effective reading distance of up to 2 cm. Non‑metallic enclosure materials have negligible impact on reading performance, whereas metallic materials significantly attenuate the RFID signal. These results indicate that the proposed design is effective and feasible as a low‑cost embedded security enhancement that integrates the national ID infrastructure into motorcycle access control

Design of a Flood Detection System Using VL53L1X Sensor Based on SMS Gateway
type: item
description: Floods often occur suddenly, disrupting community activities, damaging infrastructure, and threatening human lives. Traditional flood monitoring methods, such as using rulers at dams or floodgates, are less effective because they cannot provide real-time alerts. Therefore, a more efficient and responsive system is needed. This research focuses on the design and development of a flood early detection system using the VL53L1X sensor integrated with an SMS Gateway. The system is capable of monitoring both water levels and rainfall in real-time and automatically sending notifications when potential flooding is detected. The study applies the ADDIE method—Analysis, Design, Development, Implementation, and Evaluation—to ensure systematic development and testing. Based on experimental results, the system successfully measured water levels and rainfall while sending SMS notifications. In the first test, the water level was 29.8 cm with 19.25 mm of rainfall, categorized as safe. In the second test, the water level rose to 59.9 cm with 45 mm of rainfall, generating a warning alert. The third test showed a water level of 81.5 cm and rainfall of 47.75 mm, categorized as danger. The system demonstrated reliable performance, with an average notification delay of just three seconds, proving effective for early flood detection

Arima Modeling for High-Frequency Channel Response in Equatorial Region
type: item
description: Indonesia, an archipelagic country located along the equator, is highly vulnerable to natural disasters. At the same time, its geographical conditions require reliable telecommunications to strengthen connectivity across its many islands. One effective solution is the utilization of High-Frequency (HF) communication technology, which enables long-distance communication and supports broadcasting-based telecommunications. This approach can expand available frequency channels, making HF radio communication an important tool for disaster-prone regions like Indonesia. To optimize HF communication, researchers have developed various models of HF channel radio systems, often represented statistically and implemented through channel simulators. Among these approaches, the Auto Regressive Integrated Moving Average (ARIMA) model has been identified as particularly suitable. This is because ARIMA can handle the non-stationary characteristics of time-series data, such as those found in HF channel attenuation measurements. In the modeling process, several ARIMA configurations were tested, including ARIMA (0,1,1), (0,0,5), (1,0,0), (1,0,1), (1,0,2), and (0,0,4). From these options, two models—ARIMA (1,0,0) and ARIMA (1,0,2)—showed the closest fit to the observed data. The final selection was made using the Akaike Information Criterion (AIC), where the ARIMA (1,0,2) model emerged as the best. This model provides the most accurate representation for predicting HF channel attenuation, supporting more reliable telecommunications systems for Indonesia.

type: item
description: The reliability of the electricity distribution system is essential to ensure continuous service to consumers. Maintenance is necessary to uphold this reliability. However, on the SUTM (Medium Voltage Overhead Line) network, maintenance often requires power outages, causing losses for both consumers and the company due to undelivered electrical energy (kWh). This study aims to analyze the SAIDI and SAIFI values, as well as the amount of kWh before and after implementing PDKB (Live Line Maintenance) at PT PLN (Persero) UP3 Langsa. The research uses a quantitative descriptive method with data collected through observation and analysis of kWh, SAIDI, and SAIFI metrics. The results show that PDKB-based maintenance saved 1,457,823.97 kWh with a financial gain of Rp. 1,135,391,541.48. The SAIDI and SAIFI values were 819.456 minutes/customer and 9.29 times/customer, respectively. In contrast, maintenance without PDKB resulted in a loss of 3,921,103.2 kWh or Rp. 3,136,882,560, with higher SAIDI and SAIFI values of 1533.84 minutes/customer and 10.04 times/customer. These findings indicate that lower SAIDI and SAIFI values reflect improved service quality, enhancing the company’s image and reducing losses from power distribution interruptions

Design and Development of a Monkey Repellent Device Based On Ultrasonic Waves at the Engineering Prayer Room, Malikussaleh University
type: item
description: The presence of wild monkeys in the Engineering Prayer Room at Malikussaleh University has become a severe problem for cleanliness and worship activities. Monkeys often damage equipment and disturb the comfort of pilgrims, causing material losses and threatening environmental cleanliness. Traditional methods to repel monkeys have proven ineffective for a long time, so technological solutions such as ultrasonic waves are needed. This study looked at the effects of using various ultrasonic frequencies on monkeys at multiple distances to determine their effective range of distraction. The results show higher frequencies cause more significant interference, especially at close range. At 23 kHz and 26 kHz, monkeys were only disturbed at a distance of 1 and 2 meters, without disturbance at 3 and 4 meters. The frequencies 29 kHz and 32 kHz show interference at a distance of 1 and 2 meters, with variations at 29 kHz at 3 meters. At 35 kHz, the monkeys were highly disturbed at 1 meter, disturbed at 2 meters, and slightly disturbed at 3 and 4 meters. The 38 kHz and 41 kHz frequencies cause significant interference at 1 and 2 meters, and interference is still felt at 3 and 4 meters. Thus, using frequencies above 30 kHz has proven effective in driving away monkeys up to a distance of 4 meters, with the highest intensity of interference at a distance of 1 to 2 meters. It is hoped that using ultrasonic technology can maintain cleanliness, safety, and comfort in prayer activities in prayer rooms and demonstrate commitment to sustainable and environmentally friendly solutions.

Design and Construction of an Electric Whip for the Implementation of Criminal Law in Aceh
type: item
description: According to Qanun Jinayat, caning punishment in Aceh needs to be applied in a way that is both efficient and quantifiable. Designing an electric machine-based whipping device that controls the voltage (between 100 and 150 volts) according to the device's strength is the goal of the study. Using an experimental approach, this study displays the outcomes of 10 lashes at 100 volts for 10 seconds. It just takes 4.38 seconds at 150 volts. The punishments of khalwat (10–30 lashes), khamar (40–60 lashes), and zina (100 lashes) were used to test the system. The Aceh Jinayat law's concepts of justice and welfare are used to adjust the tension to the convict's circumstances. It is anticipated that this specially made whipping machine will be the most appropriate and compassionate way to administer caning punishment in Aceh. Therefore, this design provides a quantifiable, quick, and efficient method without disregarding the humanitarian element in Aceh's application of Islamic law.

Performance Analysis Of Centrifugal End Suction Pump And Three Phase Induction Motor In The Distribution Pumping Station of PDAM Tirta Mountala, Aceh Besar Regency
type: item
description: This study evaluates the efficiency performance of the motor-pump system used by the regional water utility company to identify strategies for improving efficiency. The three-phase induction motor utilized is highly dependent on the quality of the supplied voltage. The primary focus of this research includes analyzing the efficiency performance of the system, examining the electrical parameters of the three-phase induction motor, which include voltage and current imbalance, power factor, and Specific Energy Consumption (SEC). Another focus is the optimization of the motor-pump system and estimating the potential energy savings and operational cost reductions achievable within one year. The research method involves measuring electrical and hydraulic parameters. Electrical parameters were measured using a 3-phase power analyzer (type DW-6195), which records current, voltage, frequency, power, and power factor. Hydraulic parameters were measured using an electromagnetic flow meter for flow rate readings, a manometer for pressure measurements, and a measuring tape to measure the water level in the reservoir tank. All measurement results were tabulated and further analyzed to evaluate the performance of electrical parameters and compare them to the hydraulic performance of the system. The results revealed that the efficiency of the PDAM motor-pump system is below 50%, indicating the need for a comprehensive system revitalization. An inspection of electrical parameters showed that voltage deviation is below 10%, voltage imbalance is below 5%, and current imbalance ranges between 5.65% and 7.35%. All electrical parameters comply with IEEE standards. The power factor, at 0.85, also meets electrical standards. The SEC value, below 0.44 kWh/m³, indicates potential energy efficiency. Based on the pump performance curve study, the pump system can be replaced with a pump unit that has a lower electrical power rating, reducing it from 75 kW to 55 kW, while maintaining its hydraul…
