The synthesis of copper nanoparticles in this study used a reducing agent from the extract of mercurd gum with a solution of CuSO4.5H20. The results of the synthesis of copper nanoparticles using the extract of mercurd gum resulted in the color of the solution becoming clear greenish. The reaction time greatly affects the formation of copper nanoparticles, it can be seen visually that after 5 minutes the reaction shows a color change from clear to clear greenish and a lot of precipitate is formed. As the reaction time increases, the solution gets darker. The color of the copper nanoparticle solution tends to be clear to clear greenish, the clear color will continue to increase with the length of reaction time. In XRD analysis of Cu which has been synthesized from 0.01 M mercury extract solution. It can be seen that Cu nanocrystals have been formed which are indicated by the appearance of peaks at 2q : 18.76˚, 22.24˚, and 23.99, The results of the Scanning Electron Microscopy analysis, the results of the SEM analysis in the study show that the particle sizes produced are different from one another and the distribution of particles is uneven, there are many particles that accumulate into chunks larger than other particles so that the size is not uniform and to form agglomerations. This is because the particle growth is very fast and UV-vis Confirmation of the formation of nanoparticles can be known through UV-Vis spectrophotometer observations by measuring the absorbance value in time intervals.

Textile and dyestuff industrial dye waste remain the most difficult wastewater to treat due to the complex aromatic molecular structure of industrial dyes, which are very difficult to decompose. This research was conducted on the degradation of methyl green using the photosonolysis method. The purpose of this study was to determine the optimum time and amount of ZnO used in degrading methyl green dye. The results of the percentage degradation were obtained from the absorbance value measured using a UV-Vis Spectrophotometer. (λmax) Methyl green obtained from the measurement of a UV-Vis spectrophotometer was 640 nm. The results showed that the optimum irradiation and sonication time to degrade methyl green was 60 minutes with a degradation percentage of 92.77%. For the effect of mass variation of ZnO catalyst obtained the optimum mass of 0.05 grams with a degradation percentage of 96.38%.

Abstract — Silica is one kind of porous material that is suited to adsorben. In the synthesis process, silica gel can be produced using a sol-gel method based on the sodium silicate (Na2SiO3), which is prepared by an acid. The project of this research is to establish optimum conditions in aging time and gel-drying temperatures to produce a broad surface and pore size for silica xerogel. Based on the iod's absorption of variations in aging time (14, 16, 18, 20 and 24 hours) and drying temperatures (60, 70, 80, 90 and 100°C) give the most absorption to optimum conditions of aging time at 18 hours and drying temperatures of 70°C. The presence of XRD pattern leads to amorphous nature structures that dilate at one peak in 2θ = 22.545°, which indicates synthesis of silica xerogel with a basic sodium silicate obtained from natural silica was successfully made and highly pure. Keywords — Silica, Sodium Silicate, Silica xerogel

— In 1970, Davidovits discovered an alternative binder called geopolymer. Geopolymer is a material or binder material synthesized by mixing alumina silicate source material and alkaline activator solution. One of them is Napa land. Napa soil contains high levels of SiO2 and Al2O3 with percentages of 62.70% and 31.16% based on the XRF test. NaOH solution mixed with Na2SiO3 was used as an activator whose concentration varied from 8M to 14M. The ratio of the weight of Na2SiO3 to the importance of the NaOH solution is 1.5. The characteristics of the geopolymer cement based on napa soil showed that the analysis of optimum compressive strength was achieved at a concentration of 14M. Compressive strength tests of cylindrical specimens, splitting tests, and porosity tests were carried out comprehensively to compare the samples from each composition. The higher the concentration of NaOH, the higher the compressive strength produced.

—Goethite yellow dye (α-FeOOH) is an inorganic synthesis product with natural iron sand as the basic material. Pure natural iron sand contains magnetic particles oxidized to produce Fe 3+ ions which can be used as starting materials for FeOOH compounds. Synthesis was carried out by coprecipitation method with NaHCO 3 as coprecipitation agent. The variation of the mass of iron sand is aimed at knowing the optimal comparison of the use of iron sand, H 2 SO 4 , and HNO 3 . The optimum ratio obtained between the mass of iron sand, H 2 SO 4 and HNO 3 is 3:10:10. Variations of pH synthesis were carried out at pH 2, 3, 4, 5 and 6 to produce a yellow color with different brightness. The pH causes the yellow color to get darker. The brightest yellow color was obtained at pH 2 synthesis. Characterization was carried out with DRUV-Vis to see the absorption wavelength, FTIR spectrophotometer to see the product's functional groups and XRD to see the crystal structure of the product.

Mesoporous silica is a silica solid with pores between 2-50 nm which can be used in the fields of adsorption, medicine, catalyst synthesis, material purification and stationary phase for chromatography. Mesoporous silica is generally synthesized using TEOS or TMOS, but these precursors are relatively expensive. Na2SiO3 is a precursor of mesoporous silica which is more economical and easy to obtain. Basic materials that contain a lot of silica such as chert can be synthesized into Na2SiO3. Mesoporous silica synthesis generally uses surfactants as templates for the polymerization of silica, therefore a cosolvent is needed that can act as a crystal size enlarger by interacting with surfactants. The purpose of this study was to determine the effect of the addition of hexane on the synthesis of mesoporous silica symbolized by SM and SMH5. Mesoporous silica was synthesized using the sol-gel method with the basic ingredients of Na2SiO3 from chert, P104 as a surfactant, HCl as a solvent and n-hexane as an additive to increase crystal size. Mesoporous silica was characterized using XRD. The results of measurements using XRD showed that the X-ray difragtogram pattern showed peaks at an angle of 2ϴ = 22.29o and 25.33o for SM and SMH5 products, respectively.

— Methylene blue is one of the textile industry wastes which can cause pollution to aquatic ecosystems. So we need a method to treat wastewater contaminated with dye so that it is safe to dispose of and does not pollute the environment. One of the effective methods for removing dye waste is the adsorption method. The purpose of this study was to determine the optimum absorption conditions and maximum absorption capacity of methylene blue using activatedbcarbon from the peel of a banana (Musa balbisiana Colla). In thissstudy, using the Bacht method to adsorb methylene blue dye by varying the pH and particle size. The results of this study showed that the absorption capacity at the optimum conditions of pH 6 and a particle size of 250 µm was 5.4096 mg / g and the adsorption efficiency was 86.54%.

— Pollution caused by industrial waste is a problem for people's lives, one of which is water pollution by dyes. The synthetic dye is difficult to degrade in nature, so it requires an alternative method to be able to degrade the dye. The compound C-Vaniline Kalix[4]Resorcinarene (CVKR) has great potential as an adsorbent to be developed for dye adsorption. This study aims to determine the potential of C-Vanillin Kaliks [4] resorcinnarene (CVKR) as an adsorbent for the adsorption of metanyl yellow dye using optimum condition parameters to affect the metanyl yellow adsorption process which are estimated. The CVKR obtained was in the form of a peach colored powder solid of 0.833 grams. The results of characterization with FTIR showed absorption peaks at wave numbers 3355.12 cm-1 (O-H), 1508.14 cm-1 (C=C benzene) and 1141.58 cm-1 (C-O), the results of UV-Vis measurements showed the presence of adsorption of conjugated dienes at a wavelength of 299 nm with an absorbance of 3.5582 A and CVKR has a melting point is 380 0 C. Analysis of the adsorption of metanyl yellow by CVKR under optimal conditions occurred at pH 5, concentration 250 mg/L, optimum contact time 90 minutes and stirring speed 200 rpm . Adsorption inclined the langmuir isotherm pattern with a determinant value is 0.9175. The % RSD value of methanyl yellow was 1.3361%. The LOD and LOQ values were 0.27568233 mg/L and 0.91894118 mg/L in the analytical method used.
