<![CDATA[During the period of compulsory education in Indonesia, which is 12 years, the government requires mathematics as the main subject of external learning which will continue to have an impact on people's lives. The level of ability in a field of science must be measured to obtain valid data for the development of education in Indonesia. The use of Sagemath Mathematics Software in schools in Indonesia is not surprising at this time, technological developments have made the use of Sagemath Mathematics Software commonplace. The research method used in this research uses a literature study research method where researchers research the results of previous research. In groups There were 55.88% of experiments that experienced an increase (normalized gain) in the high category and 44.22% were in the medium category. Meanwhile, the average increase (normalized profit) in this group was 0.71, which is included in the high category. The results of this study concluded that students' abilities in mathematical computational thinking on Sagemath software are very high, this is due to several factors between the tendencies of students' desires and creativity of the teaching profession. Students' computing abilities when using Sagemath software can be done through students' mathematical algorithm features.]]>

<![CDATA[This study aims to describe the validity of climate change teaching materials based on science literacy and curiosity character of junior high school students. The research method used is research and development (R&D) through the modified four-D (4 D) model. This modul development procedure includes three stages, whisch are define, design and develop. The subjects of this research and development include 5 expert validators. The type of data obtained is quantitative data in the formdof product validation questionnaire scores. The results of research and development of junior high school science teaching materials based on science literacy and characterised by curiosity on the topic of climate change by expert validators obtained validity results with a total of 0.90 with valid criteria. This is reviewed from three aspects: (1) content feasibility scored 0.90 with valid criteria, (2) presentation feasibility aspect scored 0.88 with valid criteria, (3) linguistic feasibility aspect scored 0.92 with valid criteria. So it can be concluded from all the validity tests that the teaching materials developed are classified as valid criteria.]]>

<![CDATA[The part of the basil plant is the leaves which have various types of benefits if studied further. With the introduction of secondary metabolites, it can be said that basil leaves contain eugenol compounds. The eugenol compound can be used as a reducing agent in the synthesis of TiO2 nanoparticles. The precursor used in the synthesis of TiO2 is titanium isopropoxide which has an oxidation state of +4. By utilizing the green synthesis method, TiO2 was reacted with basil leaf extract and then characterized using XRD and FTIR. The resulting particle size is 10.86 nm. And FTIR shows a wave number of 874.59 which represents the Ti-O functional group. Photocatalytic activity can take advantage of the synthesis of TiO2 nanoparticles by placing the nanoparticles in a methylene blue solution which has a concentration of 20 ppm and varies based on contact time and adsorbent mass. Photocatalytic activity testing obtained a degradation percentage of 79%-84% which varied based on adsorbant mass and contact time. Varying the adsorbant mass and time results in a degradation percentage that increases with each additional mass but will not increase again if it has reached the optimum phase and can reduce the degradation percentage.]]>
