Abstrak : The problem in this study is the low chemistry learning outcomes of class XI students of SMA Negeri 6 Pekanbaru. Another problem that emerged based on initial observations made by the researcher was the lack of student motivation in chemistry learning. One of the causes of low student motivation is the limited use of media in the learning process. The objectives of this study are: 1) …
ABSTRACT Propylene oxide (PO) is a basic chemical product that is widely used to produce derivative products such as polyurethane, polyether polyols, propylene glycol, glycol ethers, propylene polyols, and several other derivative products. Indonesia's PO production currently still depends on imports to meet domestic demand. Therefore, it is worthwhile to plan the establishment of a PO plant l…
ABSTRACT Methanol is classified as a basic chemical widely used to produce various derivative products such as acetic acid, formaldehyde, Methyl Tertiary Butyl Ether (MTBE), gasoline, chloromethanes, methylamines, polyvinyl, polyester, rubber, synthetic resins, pharmaceuticals, and Dimethyl Ether (DME). Domestic production has not yet met the national demand for methanol. Therefore, the establ…
The Independent Curriculum encourages flexible and student-centered learning that emphasizes in-depth understanding with the UbD approach. However, the chemistry assessment, especially on the salt hydrolysis material in SMA Negeri 4 Pekanbaru and SMA Negeri 6 Pekanbaru, has not been fully oriented towards student understanding and tends to only measure low-level cognitive aspects, so that this …
