    This study aims to determine the effect of the Quantum Teaching model on the learning outcomes of seventh grade students of Sint Aloysius Niki-Niki Catholic Middle School. This type of research is quantitative research with a quasi-experimental method and the research design used is the Nonrandomized Control group Pretest-Posttest Design. The population in this study were all seventh grade students of Sint Aloysius Niki-Niki Catholic Middle School. The data analysis technique used descriptive analysis and inferential analysis. The results showed that the post test score in the experimental class that applied the Quantum Teaching model was higher, namely 86.37 compared to the control class who applied the conventional learning model, namely 69.13. Anacova test results show the calculated F value is 0,000 or less than 0.05. This shows that H0 which states that there is no effect of the Quantum Teaching model on the learning outcomes of seventh grade students of Sint Aloysius Niki-Niki Catholic Middle School is rejected and the consequence is that Ha states that there is an effect of the Quantum Teaching model on the learning outcomes of seventh grade students of SMP Catholic Sint Aloysius Niki Niki accepted. The results of the activities of students who took part in the experimental class were also higher at 90%. compared to the control class, namely 86.65%. And the teacher's ability to manage learning in the experimental class is included in the good category, namely 98.91%.This study aims to determine the effect of the Quantum Teaching model on the learning outcomes of seventh grade students of Sint Aloysius Niki-Niki Catholic Middle School.

    Methylene blue is a cationic dye often used for various industries. Methylene blue waste harms aquatic biota. Most ways have been done to reduce the methylene blue pollution that includes photocatalytic, electrochemical, and adsorption. This study aimed to reduce the impact of methylene blue pollution on the aquatic environment and to test the adsorption isothermal for methylene blue adsorption using coconut fiber. The abundant coconut fiber waste around the Kupang city was taken and prepared to be used as an adsorbent. The characterization results showed that the active groups in cellulose were clearly described on the FTIR spectra which showed the presence of  O-H vibrations at 3296.35 cm-1, C-O vibrations were seen at 1267.23 and 1060.85 cm-1, at wavelengths 1608.63 cm-1 and 817.72 cm-1 there is a vibration from the C=C bond, while the C-H vibration appears at a wavelength of 2939.52 cm-1. The results of this research analysis showed that the adsorption of methylene blue according to the Langmuir isotherm indicated by the value of the equation of the straight line R2 being one and the direction of the curve depicting occurring the effective adsorption. The maximum adsorption capacity was 4.467 mg g-1 with the percentage of methylene blue adsorbed at 99.3%. Adsorption occurs chemically with an energy of 27.29 kJmol-1 so it can be determined that the adsorption occurs with a monolayer mechanism

The waste of blue methylene can reduce the environmental balance, especially for aquatic biota, by inhibiting the penetration of sunlight into the water. The experiment used the most natural ingredients and methods to minimize the existence of the dye. In this research, coconut husk was activated with NaOH solution and then used for blue methylene adsorption. The coconut husk started aims to reduce the pollution of the adsorbent to increase the adsorption capacity. The study result showed the optimum adsorption of blue methylene at pH 7 for 75 minutes of adsorption with the capacity adsorption of 1.41 mg g-1. The development of the kinetic study described the adsorption process according to a second-order pseudo reaction kinetic model with the constant adsorption rate of 2.54 x 10-4 g mg-1 minute-1
