Instruments that can record and transmit the sea level in real time are essential for preventing potential disasters. This study presents the design, construction, and evaluation of an instrument for measuring sea level using a pressure sensor, a microcontroller, and a GSM module. The sea level analyzed using T Tide analysis. The instrument's accuracy was established through a calibration process, resulting in a sensor reading accuracy of 96.76% and a low root mean square error of 3.24 cm. The linear regression model confirmed the strong correlation between sensor readings and actual water depth, with a coefficient of determination of 0.999. The instrument achieved an accuracy of 96.76% and a low root mean square error of 3.24 cm. Field testing over three days showed the instrument's reliability in measuring sea levels, with an accuracy rate of 91.93% and an root mean square error of 8.07 cm with a packet loss of 7.86%.

Abstract

Hydrophilic and hydrophobic coated metal foams have been successfully prepared via a cleaning procedure and a simple spraying technique to be used as a wick structure in a heat pipe. The main object of this work is to explore the effect of hydrophilic and hydrophobic layers on the metal foam and to study the properties of the metal foams. To achieve this goal, 3D-OM analyses were performed to identify the pore size of the metal foam. To observe the surface morphology and porosity of the metal foam, SEM analysis was carried out and succeeded in observing the changes in the surface roughness of the hydrophilic and hydrophobic coated metal foams. The pore diameter, porosity and density of metal foam were 633.38 µm, 48.46% and 4.62 g/cm3, respectively. FT-IR analysis was also performed with the results showing that the hydrophobic coating did not affect the overall molecular group composition. Contact angle analysis shown that the values were 74° and 112° (first day) on the hydrophilic and hydrophobic coated samples.

Abstract

This study investigates the precision of coordinate positioning using Global Navigation Satellite System (GNSS) technology, focusing on GNSS Neo Series modules and the GSM SIM 7000E module. The research aims to address the lack of comparative studies evaluating these GNSS receivers simultaneously. A field test spanning 24 hours was conducted to collect data on satellite acquisition and Horizontal Dilution of Precision (HDOP). The GNSS systems were deployed in a controlled environment at the Class I Meteorological Station Hang Nadim, Batam. The system developed comprised GNSS modules (Neo 6M, Neo 7M, Neo 8M, and GSM SIM 7000E), an ESP32 microcontroller, Arduino UNO, and a Micro SD shield module. Data processing involved converting coordinates to meters and calculating longitude and latitude errors. Root Mean Square Error (RMSE) analysis and one-way ANOVA were performed to assess accuracy and compare the GNSS receivers. Results indicate that the GSM SIM 7000E demonstrated superior satellite acquisition, leading to higher accuracy in coordinate positioning compared to the Neo Series modules. The study also identified optimal data collection times for accurate dispersion. These findings provide valuable insights into selecting and deploying GNSS receivers, enhancing performance in location-based services and scientific applications.

Abstract

New Renewable Energy (EBT) is an environmentally friendly energy source that can be continuously renewed. One of the EBT technologies that is widely used is solar panels, which utilize solar energy as an electrical resource. This research aims to analyze battery charging patterns based on using solar panels with capacities of 5WP, 10WP, and 20WP, as well as charging modules such as TP4056 and INA219 sensors to monitor voltage and amperage. The research results show that solar panels with a capacity of 20 WP have faster charging capabilities compared to solar panels with a capacity of 5 WP and 10 WP. The average battery charging time in sunny weather is around 3 hours, while the battery charging time in cloudy weather is around 6 hours. This shows that solar panels with higher capacity can increase the efficiency of the battery charging process. Keywords : New Renewable Energy, Solar Panels, Lithium-Ion Batteries, INA219 Sensors

Abstract

This study explores the spectral characterization of seaweed, Kappaphycus alvarezii, using the SparkFun Triad Spectroscopy Sensor AS7265x to assess the relationship between water content and light intensity. This research aims to provide a foundation for non-destructive monitoring of post-harvest seaweed quality using spectral techniques. The SeaSpec device was constructed using an ESP32 microcontroller, a TFT display, and the AS7265x sensor. Seaweed samples were collected from the coastal area of Karimun Islands and subjected to a controlled drying process at 40°C to determine the water content in the seaweed. The spectral data were recorded across 18 channels in the visible and infrared spectra, highlighting distinct patterns that correlate with varying moisture levels. A multiple linear regression analysis was employed to determine the contributions of individual spectral channels to water content prediction, revealing that each channel has its own unique contribution to the model. Coefficient of determination (R²), percentage error (%), and percentage accuracy (%) were also used to assess model performance. The results indicated that higher water content corresponds to increased light intensity. The analysis indicated that the visible spectrum outperformed the infrared spectrum in predictive accuracy, with an R² value of 0.79 compared to 0.61 for the infrared spectrum. This indicates that the visible light spectrum is more effective in predicting water content in K. alvarezii. The findings underscore the potential of spectral analysis as a reliable method for assessing the physico-chemical properties of seaweeds, advancing the use of optical sensors in aquaculture and environmental monitoring while paving the way for future research.
