This study aims to determine: the binding capacity of cloth toward methylene violet (MV) dye, the rate of releaseof methyl violet from cloth due to washing, and the effect of the addition of the mordant to the binding capacity and the rate of release. pH, temperature, and equilibrium time were always maintained in all experiments. Data of binding capacity were collected by isothem experiments and performed by measuring the concentration of methyl violet bound by cloth at various added-concentrations of methylene violet. Collected data were analyzed with a Langmuir and Freundlich isotherm equations. Data of release rate were collected by mesuring the concentration of free methylene violet dye in solution due to washing as a function of time. The release data were analyzed using the Lagergren rate equation. The analysis showed that bonding between methylene violet and cloth occurs with releasing protons and via hydrogen bonds. Binding capacity was represented by the Freundlich isotherm equation on which the capacity was decreased by the addition of mordant, with represented bythe constants of k 1 , 2.45 x 10 -8 and 1.75 x 10-8 M MV per gram of cloth, respectively. The addition of mordant also deceleratedoubly the releaseof MV from cloth due to washing whose constants k - 2 were 2103.039 and 1013.958 mmol g-1 min-1, respectively.

The aim of this research was to determine the effect of pH on the adsorption of micronu- trients of Ca 2+ and K . by silica from lapindo mud. Data were collected by the adsorption experiments, on which 3 grams of silica separated from Lapindo mudwere dissolved in 300 mL of 0.0001 or 0.001 M Ca + 2+ or K ., and stirred for 2 hours. The pH of suspension was varied and left for equilibrate for 2 hours, and a sample was taken and measured for free concentration of K + + .cation using Flame Atomic Emission Spectroscopy and of Ca using Atomic Absorption Spectroscopy (AAS). The pH ranges were from 3 to 10. Temperature o 30 C and contact time of 2 hours were maintained. The research showed that both cations were adsorbed in sigmoid curve, increased with increasing pH values. In entire ranges of observed pH, the percentage of cations adsorbed by silica was not different signiﬁ cantly. The adsorbent of silica formed silanol (SiOH) in water. The –OH groups of silica were protonated forming SiOH o at lower pH and deprotonated forming SiO¯ at higher pH. Wether Ca 2+ or K + 2 + . cations were bound to silica surfacesvia cation exchange reactions, on which Ca2+ or K + . exchanged H of SiOH using one charge of the cations, forming [SiO(CaO)] for Ca 2+ , and [SiO-K] for K

This research was conducted to analyze the effect of using the media of chemondro and hybrid video conferences in the teaching-learning toward students’ self-efficacy and students’ achievement on the subject of solubility and solubility product. The instruments of this research are the questionnaire and solubility and solubility product test. Thus, the research was set as quasi-experiment research using post-test only and non-equivalent control group design. By purposive sampling technique, the samples from 6 classes composed of 2 public senior high schools were selected. The classes were divided into 2 of hybrid learning with video conference and chemondro game (A), 2 classes of hybrid learning with video conference (B), and 2 classes of chemondro game (C). The corresponding data were collected on the basis of a self-efficacy learning questionnaire and a multiple-choice posttest of students' achievement in the subject of solubility and solubility product. The data were then tested by Manova. The results show that there was a significant difference in students’ self-efficacy and students’ chemistry cognitive achievement among the three classes, A, B, and C.

One effort to present abstract concepts is the use of learning media. Electronic can provide opportunities for students to learn independently without relying on them. This study aims to determine the feasibility and practicality of guided inquiry-based electronic modules, the difference in students’ chemical literacy abilities in each class, and the effectiveness of learning using guided inquiry-based electronic modules on students’ chemical literacy. This research is a 4D development model consisting of Define, Design, Develop, and Disseminate. This study was conducted at Senior High School 1 Tembilahan Hulu, and the participants were 60 high school students and five chemical teachers, and two validators– data collection in questionnaires and tests. This study used a quasi-experimental method and a post-test-only control group design. The data analysis technique in this research is a descriptive statistical analysis technique of percentages. The results showed that the feasibility of the product assessed by validators showed that the guided inquiry-based electronic module was proper to use in this research. The practicality of the chemistry teacher assessment shows a very good category, the chemical literacy of students who use guided inquiry-based electronic modules in learning is better than students who do not use guided inquiry-based electronic modules in learning. The effectiveness test showed that learning using an electronic module based on guided inquiry scored 0.74 in the medium category.
