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.

This research aims to provide information about Vocational High Schools (VHS) based on the Regional Public Service Agency (RPSA). This descriptive qualitative research uses a literature study approach, which includes several activities related to library data collection methods, reading, recording, and processing research materials. Meanwhile, content analysis is the analytical approach used. The findings of this study reveal various aspects of the management of VHS based on the regional public service agency: definition, benefits, objectives, requirements towards VHS-RPSA, and organizational structure. The management of VHS-RPSA is not for financial gain but to satisfy customers (students and communities) by providing autonomy in handling finances towards school independence, which has several benefits, such as autonomy in financial planning patterns, improved human resources, improved learning, improved facilities and infrastructure, strengthened character education, and improved cooperation. This research enhances the understanding of VHS management within the RPSA framework, contributes to education governance and public service administration to improve the quality of VHS education, and paves the way for future research.

AbstractThis research is backed by low student learning outcomes. This research aims to determine: 1) The difference of learning outcomes of grade X class MIA SMA Bina Utama Pontianak who use the media simulation Physic Educational Tecnology (PhET) and students who do not use the PhET simulation media on materials molecular shape, 2) determine the influence of the use of the PhET simulation media to study outcomes on the subject of chemical materials molecular shape grade X class MIA SMA Bina Utama. Samples are selected based on the saturated sample technique. The form of research in use is (Quasi experimental design) by designing the research used is "Nonequivalent control group Design". The data collection tools used are test learning results. Based on the analysis of posttest data using Test T obtained the value of Sig (2-tailed) by 0.000. This shows that there is a difference in learning outcomes between students who are taught using the PhET simulation media and students who are tutored without using the PhET simulation media. Learning to use the PhET simulation media on the molecular material in SMA Bina Utama Pontianak has influenced the effect size of 2.45 on the increase of student learning outcomes.
