“…2. Degradation intensity of the absorption spectra represent presence of decreasing in the concentration of methylene blue in the water [1], [7][8]. The performance of Waste frying oil C-Dots from waste frying oil in the water purification were measured from the length time until there was no absorption spectra of methylene blue in the water.…”

“…Degradation intensity of the absorption from methylene blue solution appear differently in the some process of water purification without photocatalyst C-Dots, using phtotocatalyst C-Dots from frying oil and waste frying oil. Degradation intensity of this absorption is proportional with the decreasing of methylene blue concentration in the water [7,8]. The performance of C-Dots from waste frying oil were observed more effectively as a photocatalyst in the water purification process of methylene blue solution.…”

“…TiO 2 can be effective as a catalyst in the photocatalyst process when obtaining solar irradiation or UV light directly. A high density of TiO 2 about of 4.32 g/cm 3 , causes TiO 2 must to have a modifications by immobilization of TiO 2 particles on a low density and transparent polymer [7,8]. This modification have to do so that TiO 2 particles can float above the water surface and receive solar irradiation or UV light directly.…”

Abstract. Carbon Nanodots (C-Dots) from waste frying oil could be used as a photocatalyst in water purification with solar light irradiation. Performance of C-Dots as a photocatalyst was tested in the process of water purification with a given synthetic sewage methylene blue. The tested was also conducted by comparing the performance C-Dots made from frying oil, waste fryng oil as a photocatalyst and solution of methylene blue without photocatalyst C-Dots. Performance of C-Dots from waste frying oil were estimated by the results of absorbance spectrum. The results of measurement absorbance spectrum from the process of water purification with photocatalyst C-Dots showed that the highest intensity at a wavelength 664 nm of methylene blue decreased. The test results showed that the performance of photocatalyst CDots from waste frying oil was better in water purification. This estimated that number of particles C-dots is more in waste frying oil because have experieced repeated the heating process so that the higher particles concentration make the photocatalyst process more effective. The observation of the performance C-Dots from waste frying oil as a photocatalyst in the water purification processes become important invention for solving the problems of waste and water purification.

“…Then, the solid waste dried was crushed to form fine powders and finally mixed with several weights of PU formed from polyol and diisocyanate polymerization. The weight composition of polyol and diisocyanate is 5:1 [18]. The PU-solid waste composite then was hot-pressed at pressure and temperature of 4 metric ton and 80 C respectively on a mould of 4 cm in diameter.…”

Effect of turbulence modelling to predict combustion and nanoparticle production in the flame assisted spray dryer based on computational fluid dynamics AIP Conference Proceedings 1712, 040002 (2016) A solid waste composite was successfully made. Preliminary, the composite was synthesized using polyurethane (PU) as binder mixed with the solid waste using simple mixing method and then hot-pressed at at pressure of 4 metric-tons and temperature of 80 C for 20 minutes. To enhance its strength, quartz sand partilces with varied content then were added into the PU-solid waste mixture. From the compressive strength test, it was obtained that PU/solid waste composite with PU fraction (w/w) of 0.43 has optimum compressive strength of 38.91 MPa. Having been added quartz sand having average particles size of 0.94 m, its compressive strength attains maximum at 40.47 MPa for quartz sand fraction (w/w) of 4.27 x 10 -3 . The strength is comparable to that of clay brick, slate stone, sandstone, limestone, alder wood, aspen wood, black cherry and pine woods. Therefore, this composite is very adequate to compete the building materials such as the bricks, stones and woods.

Problem statement: Pollutions of water bodies by dye wastes from textile industries and other sources have become critical consideration. A photocatalytic technique using semiconductor materials such as Titanium Dioxide (TiO 2 ) activated by lights has been considered as one economical method to solve this problem. Approach: We attached titanium dioxide on the surface of polymer grains as photocatalyc agents using a cylinder milling method. Photodegradation processes were observed in decomposition of Methylene Blue (MB) solutions, as waste model, under solar illumination. Several parameters were optimized such as the milling temperature, the milling period, number of coated grain layers on the surface of the waste. The repeatability of using the coated grains was also sipected. Results: Two layers of TiO 2 coated grains resulted the optimum decomposition rate of the MB solution. The milling temperature of 100°C and the milling period of 90 min produced the optimal decomposition rate. After five times repetition, the TiO 2 coated grains still function well by decomposition up to 97% MB compound. Conclusion: These materials have the potential in large scale wastewater treatment in the tropical regions and nearly do not require a complicated late handling in the process of separating the catalyst for treated water as well as requires very small energy, expect the sunlight energy.
