    Most of the students had difficultyin understanding the concept of chemistry  which is abstract and cannot connect the concepts studied with the phenomena in everyday life.This is because the instructional media and learning models used by the teacher do not pay attention to submicroscopic representations and do not link chemistry with the environment around students.This study aims to develop Chemical Interactive Multimedia (CIM) based on PBL (Problem Based Learning) to improve students' Generic Science Skills (GSS). PBL-based CIM was developed on the concept of salt hydrolysis in a tutorial format. This study was a Research and Development using the ADDIE design. The research procedure consists of five stages, namely Analyze, Design, Development, Implementation, and Evaluation. The PBL-based CIM effectiveness test against the GSS of MA Darul Habibi NW Paok Tawah students was carried out at the implementation stage using a one-group pretest-posttest design. The instrument used was in the form of a questionnaire to obtain eligibility data and student responses, as well as a description test to obtain KGS data. CIM based on PBL feasibility data will be analyzed using a five-scale absolute norm, student responses were analyzed descriptively, and GSS data were analyzed using a normalized gain score (N-gain). The validation results show that PBL-based MIK has an average score of 92% which means it was very feasible.The limited trial of 12 students stated that PBL-based CIM met the aspects of appearance, readability, language, and ease of use very well.The results of PBL-based CIM trials in learning can increase students' GSS which is indicated by an average N-gain score of 58% in the moderate category.Therefore, it can be concluded that PBL-based MIK was successfully developed in the very feasible category and could improve students' GSS

    Polymer films have become a material for research recently because polymer films have an important role in the application of basic sciences. The polymer film has good mechanical, electrical and optical properties to be used in many applications, one of which is a polymer film that has the potential to be irradiated into a dosimeter. Therefore, modification of polymer film one of which is gamma ray irradiation is important to be further explored. This study aims to explore the effect of gamma ray irradiation on the optical absorption of polymer film blend PVA (polyvinyl alcohol) -trichloroacetid acid (TCA) -methylene blue (MB). Preparation of polymer films by chemical processes using the solvent-casting method. Each polymer film was irradiated with gamma rays with radiation doses ranging from 0 kGy to 14 kGy. Optical absorption was measured using a UV-VIS spectrophotometer with a range of wavelengths ranging from 200 nm to 700 nm. The results showed that three optical absorption peaks were formed on the polymer film PVA-TCA-MB due to gamma ray radiation at wavelengths of 360 nm, 440 nm, and 560 nm. Gamma ray radiation has an effect on optical absorption, where the optical absorption value of polymer film for the first peak (360 nm) and second peak (440 nm) decreased along with the increase in the dose of gamma ray irradiation, but for the third peak (560 nm) there was an increase in the optical absorption value along with an increase in the dose of gamma ray irradiation. The results of further studies are described in this article
