Abstract

This paper presents a novel approach for tracking the peaks in the FBG spectrum using the Gaussian polynomial method. The proposed algorithm involves preprocessing the FBG signal, detecting the peaks, and fitting the peaks with a Gaussian function. The performance of the algorithm is evaluated using both simulated and experimental FBG spectra. This method involves fitting a Gaussian function to the peak of interest and using the fitted parameters to estimate peak height, width, and location. The method is highly accurate and precise and can provide detailed information about peak shape and position, making it effective for tracking complex or overlapping peaks. However, the method can be computationally intensive and may require careful selection of initial parameters to ensure accurate results. Despite these limitations, the Gaussian polynomial method is a powerful tool for peak tracking and analysis in various application.

Abstract

In this study, zinc oxide (ZnO) and silver (Ag) nanoparticles were synthesized using Annona muricata leaf extract as a reducing and stabilizing agent with variations in the molar ratio of 1:3, 1:5, and 1:7. Optical characterization using UV-Visible spectroscopy revealed that the variations of molar ratio influence the absorption peak and band gap energy of the resulting ZnO and Ag. UV-Vis results show that the molar ratio 1:5 was optimal for synthesizing ZnO and Ag. The band gap value of synthesized ZnO and Ag at a 1:5 molar ratio was 3.27 eV and 2.01 eV, with absorption peaks at 355 nm and 435 nm respectively. XRD characterization shows that ZnO nanoparticles has a hexagonal wurtzite structure with lattice parameters of a = 76 Å and c = 4. 95 Å and for Ag nanoparticles has a face centered cubic structure with lattice parameters a = b = c is 4.15 Å. Annona muricata leaves extract shows photocatalytic properties that can be applied to the degradation of polluted water. This shows that ZnO nanoparticles via green synthesis using Annona muricata leaf extract is a very simple, low-cost and environmentally friendly method.

Abstract

This study explores an innovation based on IoT and biomass energy for the efficient production of processed food, specifically crackers. Biomass energy, derived from plant materials, is utilized to generate heat in the processing room. This innovation significantly reduces the processing time for crackers to just 2 hours, compared to the conventional method that requires 2 days of sun-drying. The biomass energy source used in this study includes rambutan tree trunks, which not only provide efficient heat but also impart a pleasant aroma to the final product. The research employs a direct experimental method to design and implement this technology in industrial settings. The primary ingredient for the crackers is cassava, mixed with fish, shrimp, and jengkol. The heat energy generated from the combustion of rambutan tree trunks is effectively utilized in the combustion chamber. Observations indicate that the crackers produced are of high quality, with appealing color and fragrance, making them suitable for market distribution. This innovation demonstrates the potential of combining IoT and biomass energy to enhance food processing efficiency and product quality.
