Currently, nutrients are analyzed using spectroscopy and electrochemical techniques, which are tedious and sophisticated. This study was conducted to develop a localized surface plasmon resonance (LSPR) fiber optic sensor technique to measure how much content of these nutrients should be added in the soil to increase crop fertility. The main objectives of this study are to study the LSPR fiber sensor technology on NPK in hydroponic systems, to create a fiber optic sensor technique for measuring NPK in hydroponic systems, and finally to characterize the performance of fiber optic sensors for measuring NPK in hydroponic systems. The utilization of the sensing materials, chitosan in this work is to improve the sensitivity feature of the sensor. Chitosan is coated on the surface of the tapered optical fiber prior to the LSPR NPK detection. The results of the absorption spectra will be visible at the end of the experiment where the obtained data are analyzed using SpectraSuite software. The results show that a good linearity was obtained when used AgNP/chitosan as the sensing material with the sensitivity of 0.041 nm ppm-1 in comparison to that of AgNP with the sensitivity of 0.039 nm ppm-1. A better limit of detection (LOD) and limit of quantification (LOQ) was also observed for AgNP/chitosan which are 35.61 ppm and 107.91 ppm, respectively. Meanwhile, AgNP exhibits LOD and LOQ of 106.16 ppm and 494.43 ppm, respectively. It is expected that this work will be a good contributor to the United Nations Sustainable Development Goals (UN SDG), No. 2: Zero Hunger.","PeriodicalId":318457,"journal":{"name":"Jurnal OptoElektronik","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121801972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main solutions for high-speed data transfers for this objective are millimeter-wave RF signals. It is difficult to produce these high-frequency RF signals on the electrical field, so more study is given to the photonic generation of these signals. In this study, the utilization of a dual-drive Mach – Zehnder Modulator (DD-MZM) illustrates a special optical millimeter-wave(MMW) generation. A new method for producing a local oscillator frequency quadrupling optical carrier suppression (OCS) MMW signal utilize two equivalent DD-MZMs based on this form is shown.

A self-started DS mode-locked pulse was observed at 1559.89 nm central wavelength with 3-dB bandwidth of 19.72 nm at threshold pump power of 33.5 mW. Its pulse width of 7.89 ps was recorded at 7.94 MHz repetition rate. The nature of pulse splitting was observed up to three pulses which were separated with 2.62 ns time spacing with the increment of pump power until 134.2 mW.

Gold nanoparticles (AuNP) had been incorporated with the nanocomposite material to induce strong LSPR responses. CS/rGO nanocomposite was coated on top of AuNP and had been utilized as active layer for Pb(II) ion sensing. The morphology and physical properties of gold nanoparticle-chitosan/reduced graphene oxide (AuNP-CS/rGO) nanocomposite was studied using field-emission scanning electron microscopy (FESEM), atomic force microscopy (AFM) and x-ray diffraction (XRD) analysis. FESEM exhibits a rough and wrinkle surface of AuNP-CS/rGO after the addition of rGO. AFM shows a higher surface roughness for AuNP-CS/rGO due to the presence of oxygen atoms in rGO where these oxygen atoms provide more sites for adsorption of Pb(II), hence enhance the sensitivity of the sensor. A good sensitivity of the LSPR sensor for detection of Pb(II) utilizing AuNP-CS/rGO was obtained which is 1.544 ppm-1 and the linearity of the sensor are 0.99 and 0.97.
