Abstract

Traditional clam drying often suffers from energy inefficiency and inconsistent product quality due to manual temperature control that is unable to respond to dynamic environmental changes. This study proposes an adaptive hybrid control system integrating Fuzzy Tsukamoto and PID to enhance thermal stability and drying performance. Temperature and humidity were monitored in real time using a DHT22 sensor, while fuzzy inference and a self-tuning PID mechanism automatically adjusted control parameters. Performance was evaluated through error metrics, temperature stability, drying rate, and statistical validation. The system improved thermal efficiency to 85.2%, reduced Integral Absolute Error by 41.3%, decreased drying time by 22 minutes per cycle, and lowered overshoot by 87.3%. The optimal operating window occurred between 11:00–12:00 with a minimal error of 0.5 °C and a fuzzy output of 64.3, indicating a medium–fast drying rate. Temperature stability of ±0.8 °C results in a more uniform distribution of water content, texture and color, thereby increasing the selling value of the product. These findings demonstrate the strong potential of applying adaptive Tsukamoto–PID control to the seafood-based drying industry to improve process efficiency and quality consistency.

Abstract

HIV/AIDS is a frightening disease for Indonesian society today, so that people with HIV/AIDS often get excessive stigma and discrimination. The design of this study was an observational quantitative study with a cross sectional approach with a research focus directed at analyzing family support and service quality on the utilization of the VCT Poly and compliance of HIV / AIDS patients in undergoing antiretroviral therapy (ARV). at Gambiran Hospital, Kediri City with a sample of 109 respondents taken by Accidental Sampling technique. The results showed that most respondents had sufficient family support, namely 56 respondents (51.4%). Most respondents rated the quality of service in the moderate category as many as 56 respondents (51.4%). Most respondents had moderate utilization as many as 55 respondents (50.5%). Most respondents were not compliant with antiretroviral therapy (ARV), as many as 65 respondents (59.6%). The results of the study using the Path Analysis Test showed a p-value <0.05, so H0 was rejected and H1 was accepted, so it was concluded that there was a significant effect of family support and service quality through the use of VCT Poli on the compliance of HIV / AIDS patients in undergoing antiretroviral therapy (ARV) at Gambiran Hospital, Kediri City. Compliance of HIV / AIDS patients in undergoing antiretroviral therapy (ARV) is influenced by family support, service quality and utilization in the VCT Poly itself. So that patients need to be given good support and improve the quality of services available at the VCT Poly.

Abstract

Background: Antibiotic resistance has become a major global health concern, including in periodontal therapy. Therefore, alternative antimicrobial approaches that do not rely on antibiotics are required. Purpose: This study aims to evaluate the in vitro antibacterial effect of the diode laser on Porphyromonas gingivalis associated with periodontitis. Method: This study employed an in vitro experimental design with a control group and a treatment group. A diode laser with a wavelength of 660 - 900 nm was applied to the P. gingivalis cultures with exposure times of 5, 10, and 15 seconds. The bacterial growth was assessed by measuring the inhibition zone diameter. Result: The results demonstrated a significant reduction in P. gingivalis growth following diode laser irradiation, with longer exposure times producing larger inhibition zones. Conclusion: Diode laser irradiation exhibited significant in vitro antibacterial activity against P. gingivalis. These findings indicate that diode lasers have potential as an alternative antimicrobial modality in periodontal therapy and warrant further investigation through in vivo and clinical studies.

Abstract

High water consumption in retort sterilization processes and the disposal of drain water with reuse potential highlight the need for an objective and automated water reuse feasibility assessment system. This study aims to develop an automated decision-making system based on Mamdani fuzzy logic to evaluate the reuse feasibility of retort drain water using turbidity, pH, and Total Dissolved Solids (TDS) parameters. The scope of this research includes the design of a multi-parameter monitoring prototype, the implementation of a food-grade-based fuzzy inference system, and the integration of decision results with automated valve control. The study adopts a research and development approach, in which sensor data are processed in real-time using a Mamdani fuzzy inference system consisting of 27 rule bases with a turbidity-based rule override mechanism. Experimental results indicate that all sensors achieve accuracy below 1%, repeatability under 0.3%, and good linearity within their operational ranges. Fuzzy logic evaluation demonstrates a decision accuracy of 100% compared to manual calculations. Testing on 30 retort drain water samples shows that 26.67% are classified as reuse, 66.67% as treatment, and 6.67% as reject, resulting in a water-saving potential of 93.33%. The proposed system effectively improves water-use efficiency, reduces operational costs, and supports sustainable practices in the food processing industry.

Abstract

Mountain climbing is currently being popular with the public, both young people and adults. However, there are still many people who are indifferent to the physiological conditions and environmental conditions that exist on the climb. This study aims to combine these two factors, namely physiological factors and environmental factors as an effort to minimize the occurrence of accidents in climbing activities. Physiological factors, namely oxygen saturation and heart rate, are combined with environmental factors of air pressure, which will later be processed with fuzzy logic consisting of 27 rule bases. The test results on the sensor showed high accuracy with an average value of 98.21% for SpO2, 98.01% for heart rate, and 99.10% for air pressure. At the time of the air pressure value of <750 hPa the system is also capable of giving an alarm as a warning. Fuzzy logic testing  is quite effective in determining a climber's health status, where the system consistently assigns a "Normal" status at low altitudes, changes to "Alert" when the air pressure begins to decrease, until it reaches a "Danger" status in extreme conditions. This proves that the system is able to provide an early warning on the condition of a climber.

Abstract

An autoclave is a sterilization device that operates using high-pressure steam to eliminate microorganisms. However, in conventional systems, pressure regulation is still performed manually, which can lead to inconsistencies in the sterilization process and reduced effectiveness. This study developed an automatic pressure control system based on a digital pressure sensor, controlled by an Arduino Uno microcontroller and equipped with an ESP8266 module for real-time monitoring via the Internet of Things (IoT). The system also utilizes a MAX6675 temperature sensor, a solenoid valve as a pressure actuator, and an LCD as a local interface. Testing was conducted at three pressure settings (10, 15, and 25 psi) for a duration of 15 minutes. The results showed that the system was able to maintain pressure with a fluctuation tolerance of ±0.3 psi and successfully transmitted temperature and pressure data to a cloud dashboard in real-time. This system is considered effective in improving the efficiency, accuracy, and safety of the sterilization process, and has the potential to be implemented in medical and laboratory facilities.
