Limited face-to-face learning (PTMT) has been carried out but the implementation of the learning process which lasts 30 minutes for one meeting in learning makes the teacher only convey essential ...material. Face-to-face learning is more effective than online learning. Motivation is one of the important factors in the success of a learning. This study aims (1) to determine the science learning motivation of class VIII students of SMPN 4 Pontianak even semester 2021-2022 during PTMT, (2) to determine the relationship between learning motivation and science learning outcomes for class VIII students at SMPN 4 Pontianak even semester 2021-2022 during PTMT. The research subjects were students of class VIII SMPN 4 Pontianak. The research method is descriptive with a quantitative approach. Science learning outcomes are obtained from the average daily science test scores of students. This research is a descriptive research with a quantitative approach. Data collection techniques use direct, indirect, and documentation communication. Descriptive statistics were used as a data analysis technique. The results showed that the average learning motivation was 70.81% while the percentage of learning outcomes was 81.4%. Both motivation and learning outcomes are included in the high category. The results of the Spearman's Rho test between science learning motivation and science learning outcomes obtained (r = 0.019) < ( r = 0.05) which means that there is a relationship between motivation and science learning outcomes for SMPN 4 Pontianak students, namely the higher the motivation, the higher the student learning outcomes. the higher it is. The results of this study can be concluded that the science learning motivation of SMPN 4 Pontianak students in the even semester of 2021-2022 is high with a percentage of 70.81%. There is a significant and positive relationship between learning motivation and learning outcomes for science students of class VIII SMPN 4 Pontianak even semester 2021-2022 during PTMT.

Liver, colon, and cervical cancer are the top three types of cancer which rank in the top five worldwide in terms of incidence and mortality. Simpur air (Dillenia suffruticosa)plant has traditionally ...been used for the treatment of various diseases, one of which is cancer. This study aims to prove cytotoxic effect and selectivity of simpur air wood bark fractions against liver HepG2, colon WiDr, and cervical HeLa cancer cells. Simpur air wood bark is macerated using 96% methanol. The methanolic crude extract was fractionated with the liquid-liquid partition method using n-hexane and ethyl acetate. Cytotoxicity test using MTT assay method. The result showed that the methanol extract, n-hexane fraction, ethyl acetate fraction, and methanol fraction in liver HepG2 cancer cells had IC50 values 179,32±13,55; 85,14±8,58; 140,08±22,63; >500 µg/mL and in colon WiDr cancer cells had IC50 values 133,02±27,64; 41,54±37,58; 124,76±17,22; >500 µg/mL. Meanwhile, all fractions had IC50 values >500 µg/mL in HeLa cervical cancer cells. These data indicate that the n-hexane fraction in WiDr cells is potentially cytotoxic and selective with a selectivity index value greater than 3. Thus, simpur air wood bark has the potential to be developed as an anticancer drug candidate.
