Nd3+: crystal is widely used as an optical gain medium in many applications such as light sensing, lasing medium, telecommunication, etc. Unfortunately, crystal development is an uneasy fabrication and high-cost production. Nowadays, investigation of glass as a host matrix of the gain medium is more attractive due to their potential for replacing crystal. Nd3+ion-doped various glasses such as B2O3, TeO2, P2O5and SiO2 have been widely investigated. However, the effect of B2O3 and SiO2 in Nd3+ion-doped phosphate glass has not been observed in detail. In this work, glass medium with the formula of 60P2O5:15B2O3:10Al2O3:13Li2O:2Nd2O3 (PBAlLiNd) and 60P2O5:15SiO2:10Al2O3:13Li2O:2Nd2O3 (PSAlLiNd) fabricated by melt and quenching technique. This technique is a simple and inexpensive method so that it is one of the solutions to decrease the cost production. The glass sample was melted at 1200 °C for 180 minutes and annealed at 500 °C for 180 minutes. The physical (density and molar volume), optical, luminescence (excitation and emission spectra) and radiative properties of the glass sample investigated for understanding their sensing and lasing potential. From the collected data, the glass medium strongly emits 1062 nm excited by 582 nm. The prepared glass is suitable for light sensing, especially PSAlLiNd glass due to the higher luminescence intensity. Meanwhile, the radiative properties of PBAlLiNd and PSAlLiNd were determined by the Judd-Ofelt theory. From all results analysis, PSAlLiNd glass possesses a higher stimulated emission cross section and radiative transition probability than PBAlLiNd glass. Therefore, PSAlLiNd glass is a more promising material for 1062 nm laser application. The replacing B2O3 by SiO2 in the phosphate glass system increases the luminescence and radiative properties due to the low phonon energy of SiO2 than B2O3.

Particulate matters with the diameter less than $0.1 mumathrm{m}$, as known as ultrafine particles, are derived by the natural and anthropogenic sources. The ultrafine particle concentration in the ambient air has been increasing sharply due to the combustion processes, such as motor vehicles, cooking, smoking, biomass burning, and many others. Ultrafine particles have been identified as a toxic agent for human health and linked to many diseases. In this study, we developed a new technology of an ultrafine particle filtration system using an AC low voltage 12 Volt for motorcycles. For this purpose, three electrostatic filters: F1, F2, and F3 that were made of aluminum plates were tested under two different frequencies: low-frequency LF - 60 Hz and high-frequency HF - 1300 Hz. The purpose of this study was to obtain an efficient filter for motor particle emissions. There were three standard motorcycles used as the ultrafine particle sources. The concentration of ultrafine particles was measured using a TSI P-Trak Ultrafine Particle Counter Model 8525 in five sampling times. The efficiency of the filter determined as the ratio of the ultrafine particle concentrations emitted by the motorcycle samples before and after being equipped with filters. The highest efficiency, 35%, was found in the lowest gap 0.9 mm, with an LF frequency. Meanwhile, the lowest filter efficiency, 7%, was found in the frequency of HF, with the highest gap 3.6 mm. As a conclusion, the filter efficiency depended on the voltage frequency and the filter gap.

The two-liquid diffusion process in a transparent container can be observed based on the laser beam deflection through it. A digital camera is connected to a computer to take laser beam traces on the screen and processing in the form of several image filtering procedures and algorithms to develop the digital value of the laser beam coordinates captured on the screen. Extracting image data into numerical data for the next calculation process must represent the image curve approaching the original curve when the numerical data is plotted. Some algorithms based on the OpenCV programming language was constructed, such as grayscale and applied Canny Edge Detection show significant laser beam traces and specified coordinate values. Canny Edge Detection produces sharper image data and more precise numerical data compared to previous experiments using grayscale, eroded and dilution image processing algorithms. For comprehensive observation, the character of this system is discussed with reference to the Sodium Chloride solution as an observation object. The result of the diffusivity in this experiment was $1.386times 10^{-5} boldsymbol{cm}^{2}/boldsymbol{s}$. It was found in a good agreement within an error bar to a reference, indicating the system is running well.

In order to increase the conductivity and sensitivity of boron-doped diamond (BDD) electrodes for oxygen sensors application, modification with gold nanoparticles (AuNPs) was performed. This study aims to synthesize AuNPs using allyl mercaptan as the capping agent and employ the AuNPs to modify BDD electrodes. Characterization of the synthesized AuNPs by using UV-Vis spectrophotometer showed the specific gold nanoparticles wavelength at about 510 to 580 nm, while the characterization by using Particle Size Analyzer and Transmission Electron Microscopy (TEM) showed that AuNP formed particles with an average size of $11pm 4 mathbf{nm}$. Modification of BDD surface with the synthesized AuNPs by using immersion technique under UV irradiation resulted in homogeneously distributed of AuNPs at the BDD surface with Au:C ratio around 2:98. Preliminary study of the AuNPs-modified BDD to determine dissolved oxygen solutions by using cyclic voltammetry technique suggested that the sensor has comparable capability to gold bulk electrode.

Honey content is constructed by a combination of glucose and fructose which a high sugar content. One of the honey qualities is contributed by the added adulterant in honey producing such as artificial glucose or fructose. Therefore, the soluble solid content of honey is essential to predict according to differentiate the added content of honey. The honey image was acquired using transmittance mode in the Vis-NIR range of 400–1000 nm. The complete system consists of a Hyperspectral camera at 448 bands, slider, a 200 W halogen lamp and light diffuser. The processing method performs image correction, segmentation, feature extraction, feature reduction, and a regression model. The region interest area of the honey sample was selected at the center of honey that prepared in petry-dish. Partial Least Square Regression (PLSR) was used as the feature reduction and regression model to construct the transfer model of soluble solid content based on the transmittance profile of honey. The Digital Refractometer was used to generate the reference standard of the soluble solid content. Three different producers and five types of botanical origin were used as a sample of honey. The artificial glucose or fructose was added to the original honey to produce five variants of soluble solid content. The result of RMSE for training and testing data is 0.07 and 0.45, respectively. Based on the result, the proposed system could be used as an alternative method to predict the soluble solid content in honey with excellent accuracy.

Particulate matter measurement has been found uncertainty due to the particle random and speed movement. In order to collect good measurement results, a computational model can be used as a tool. This study presents a numerical approach to forecast the particulate movement in the indoor. The paper provided information about how the simulation model can be applied in the measurement process as an assistance tool. The numerical approach was developed based on the Navier-Stokes equation. The model was tested in the indoor office room with a single air conditioner system. The exposure speed was settled at 1.5 m/s with the exposure direction 45 degrees downward. The simulation was conducted for 10 minutes for the air conditioner that were operated without any cooling or heating process. In the result, the direction of the particulate was affected by the duration of the movement. The particulate movement depended on the room. The particulate exposure direction changed as a function of time before occupying the room. The model precision is obtained 90% after the simulation data were validated. The model works well in estimating PM0.1 concentration distribution. The model can be used to determine the measurement point in real measurement.
