This research has developed the slice test device to test natural rubber composites made of magnetically modified natural zeolite on nanosilica-reinforced natural rubber composites. We tested the sample similarity with incision cadavers in surgical practice with mechanical characteristics like human tissue. Natural rubber was used as a primary component in the production of synthetic human tissue. The natural rubber was blended with magnetic particle nanosilica, an alternative filler that mixes nanosilica, natural zeolite, and magnetite. This project used several materials formulas to give synthetic human tissue the desired mechanical qualities and incision test characteristics. We used technical specifications rubber (TSR) SIR 20 with nanosilica reinforced fillers and Titanate coupling agent (TCA) as filler and elastomer binders. Samples were characterized using Universal Testing Machine and then tested with the incision test equipment specially designed by the team. Mechanical characteristics of different human body part tissue were compared to the control samples and had similar mechanical characteristics with internal human tissue characteristics. It was found that nanosilica fillers combined with magnetically modified zeolites and titanate coupling agents are potentially applicable for synthetic muscle replacement cadavers with a custom formula.

We present an exact solution of the nonlinear Schrödinger equation (NLSE) for beam propagation in nonlinear fiber optics. It is a lossy fiber system with the beam as solitons. Fiber losses are understood to reduce the peak power of solitons along the fiber length. That is due to its value depending on the fiber attenuation constant of α. Considering fiber loss features on the equation, we write one set modification of the NLSE and make models the main topic of our work. We solved the model and found a straightforward analytical solution of modified NLSE for the system via the direct solution method. To the best of our knowledge, no literature has presented such as solution yet. By substituting them into equations, we validate solutions. It is valid as an exact solution to the NLSE. Lastly, we found a solution offering soliton propagation suitable for the system under study.

A study was performed comparing the performance of UO2 and (Th,U-233)O2 fuel in small long-life PWR. The neutronic calculation carried out by PIJ module of SRAC2006 was done to a fuel cell in 10 years of operation. The calculation was conducted by varying the enrichment of U-235 in UO2 and U-233 in (Th,U-233)O2 for 1% - 20% and also by varying the fuel volume fraction for 40%, 45%, 50%, 55%, and 60%. The performance was observed by comparing the enrichment needed by each fuel type to gain criticality in 10 years, the infinite multiplication factor (k-inf) value, and the conversion ratio (CR) value. The calculation results showed that 60% fuel volume fraction gave critical conditions with the lowest infinite multiplication factor and highest conversion ratio for both fuel types. While in terms of fissile nuclide enrichment needed, (Th,U-233)O2 had better performance than UO2, because only 5% U-233 was needed in (Th,U-233)O2 while UO2 needed 9% U-235 to gain criticality in 10 years of operation.

A water quality monitoring system in hydroponics with a Total Dissolved Solid Sensor (TDS) equipped with the Arduino UNO microcontroller has been developed. The TDS SEN0244 sensor read the water sensitivity, which will display the value of the reading on the LCD. Furthermore, if the output is less than 2.30 Volts or 1000 ppm, the buzzer will sound once, and the dosing pump will rotate to automatically add nutrients A and B. The buzzer will sound twice if the output is more than 2.40 Volts or 1200 ppm. When reading the sensitivity of water (well water) with a water value of 400 ppm, the relevant results were obtained, namely, 1000 - 1200 ppm when 4 - 5 mL of the nutrient solution was added to water with a capacity of fewer than 6 liters. The appropriate value was obtained when testing the TDS sensor on several water samples. However, in the salt and soapy water samples, the voltage value reading was unstable or experienced an error. Implementing this system is expected to make it easier for the community, especially farmers, to cultivate hydroponic plants.

Bismuth substituted cobalt ferrite nanoparticle is studied for photocatalytic in this paper. Bismuth cobalt ferrite has been synthesized by the coprecipitation method and low-temperature annealing treatment. The characterization results showed that the XRD spectral pattern is consistent with ICDD 221086. The crystallite size of bismuth cobalt ferrite increases with increasing annealing temperature. FTIR results confirm the available metal-oxide at number wave around 570/cm and 475/cm which is the appearance of octahedral and tetrahedral sites owing cobalt ferrite. The photocatalyst test was carried out by varying the catalyst mass and UV irradiation time. The absorption spectrum decreases with increasing catalyst mass. The increase in UV irradiation time causes the formation of more holes (h+) and electrons (e-). So that the hydroxide reaction occurs that produces free radicals. The results of this study indicate that cobalt ferrite-based nanoparticles have potential as photocatalyst materials.
