Abstract

Activated carbon from palm kernel shell has been prepared by using ultrasonic assisted activation.  Carbonization was conducted at mild condition of 400ºC for 90 minutes heating time.  Ultrasonic irradiation (35 Watt,  42 KHz) for 15 minutes increases the carbon iodine number from 452.4021 mg/g  up to 817.4907 which is higher than SNI 06-3730-1995 requirement of mg/ g 750 mg/g for activated carbon. FTIR spectra results show that activated carbon has -OH groups at wave numbers of 3000-3500 cm-1, C = C at wave numbers of 1550-1650 cm-1, CO at wave numbers of 1000-1260 cm-1 and CH at wave numbers of 810- 770 cm-1 . Adsorption test results showed that the prepared activated carbon was able to absorb Pb+2 ion at the optimum concentration of 60 mg/L. Adsorption isotherm study conducted by Freundlich equation produces a regression coefficient R2 = 0.835 with a maximum absorption capacity of 11.0783mg/ g.

Abstract

Silica or silicon dioxide is a chemical compound with the molecular formula SiO2 which can be obtained from the synthesis of crystals, silica minerals, and vegetables. Compounds resulting from the polymerization of silicic acid, which are composed of a tetrahedral SiO4 unit chain with the general formula SiO2. Each silica atom is surrounded by four oxygen atoms. Silica forms a polyhedral network, where the bonds between oxygen tetrahendral are one and the other. Silica will form a framework that has pores that are quite open and allow other molecules to enter and undergo adsorption on the surface of the silica. Modification of silica is done by adding heat at a certain temperature, adding reagents to the active site of silica will change the silica functional group. Silica with the addition of amine compounds reacted with GPTMS can be used as nitrate anion adsorption to see the absorption capacity of silica against nitrate anions using the batch method. The factors used to see this adsorption capacity include pH at pH 7 with an absorption of 1.931463 mg/g and the percentage of absorption is 79.5%. and contact time with a time of 90 minutes with an absorption of 0.32677 mg/g and the percentage of absorption is 67.28785%.

Abstract

The synthesis of ZnO and ZnO/Au nanoparticles using the laser ablation method in liquid has been successfully carried out. Characterization of the optical properties of ZnO and ZnO/Au using a UV-Vis Spectrophotometer (Ocean Optic MAYA Pro 2000) which was measured in the wavelength range of 275 - 875 nm. The characterization results obtained are absorbance values and band gap values of ZnO and ZnO/Au nanoparticles. From this study, the absorbance values of ZnO nanoparticles were found at wavelengths of 330 and 335 nm. After obtaining the absorbance value, the band gap value was analyzed for ZnO and ZnO/Au nanoparticles, respectively, namely 3.23 eV and 3.17 eV. The decrease in the band gap value in ZnO is due to the presence of Au in ZnO nanoparticles which can replace one of the lattices in the ZnO crystal structure.

Abstract

Mesoporous silica is an inorganic materials that has high potential to be applied in various industrial fields, one of its application is the adsorption method. To maximize the adsorption of mesoporous silica, modification of the silica surface was carried out with the addition of amine compounds. The amine compound used as a modifier is dimethylamine (DMA). Mesoporous silica which has been modified with dimethylamine is used in the nitrate anions adsorption process by the column method. The adsorption capacity of the nitrate anion is 0.0917 mg/g. After being adsorbed, the desorption process was carried out to release the adsorbed nitrate anions again. From the desorption process, it was found that HCl proved to be the best desorption agent used on nitrate anions. The optimum concentration of HCl was 0.15 M with the number of  nitrate anions desorbed as much as 0.0459 mg with a 100% desorption percentage.

Abstract

In financial market dynamics, a deep understanding of economic factors that affect JCI performance such as interest rates, inflation, and the rupiah exchange rate is essential in making investment decisions. This study aims to analyze the effect of interest rates, inflation, and the rupiah exchange rate on JCI with profitability as moderation. Through a quantitative approach with purposive sampling techniques in 21 LQ45 companies, data were analyzed using SPSS 26. The results showed that interest rates had a negative and significant impact on JCI, while inflation and the rupiah exchange rate had a significant positive impact. Profitability managed to moderate the relationship between interest rates and inflation with JCI significantly. However, profitability did not have a significant impact in moderating the relationship between the rupiah exchange rate and JCI. Researchers highlighted that the combination of low interest rates, controlled inflation, and stable exchange rates boosted JCI growth and the economy as a whole.
