<![CDATA[Final grades of student who participated in the Course of Instrumental Analytical Chemistry in Odd Semester, Academic Year of 2022/2023 indicate a low student achievement. The objective of this study was to improve the instruction of Instrumental Analytical Chemistry Course by increasing student learning activities and student achievement on the topic of infra red and nuclear magnetic resonance analysis by utilizing HyperChem and ChemOffice Software. Student and lecturer observation sheet were used for measuring student and lecturer activities, respectively while, an essay test sheet was given to measure student cognitive ability. Student and lecturer activity scores for Cycle 1 were 22 and 27, respectively and fell in “Good” category. Student activity score rose up to the maximum score, 27 while, lecturer activity score remained in maximum score in Cycle 2. Lecturer activity already had a maximum score in Cycle 1 because the lecturer was well-prepared in the instruction as well as successful implementation of learning plan. Increasing student achievement was also recorded from Cycle 1 (average 80.2) to Cycle 2 (average 88.5). The percentage of student who gained score above 65 was 93% in Cycle 1 and went up to 100% in Cycle 2. HyperChem and ChemDraw are able to assist the instruction of Instrumental Analytical Chemistry course on the topic of IR and NMR.]]>

<![CDATA[[The Influence of the Problem Based Learning (PBL) Model on Students' Analysis Ability on Buffer Solution Subjects]. This research is a pre-experimental research type aims to determine the effect of applying the Problem Based Learning (PBL) model on students' analytical abilities on buffer solution materials. The research was conducted at SMAN 4 Bengkulu City with a sample of class XI IPA 3, which consisted of 36 students. The instruments used in this study were analytical ability test sheets and observation sheets. From the research results obtained (1) the average pretest-posttest results experienced a significant increase, namely 7.67 to 64.43 from a maximum score of 100. The results of hypothesis testing using a t-test at the significance level of 0.05 obtained a Sig Value (2tailed) of 0.000 with a decision H0 is rejected and H1 is accepted. This shows that the problem-based learning model has an effect on students' analytical abilities, (2) the N-gain test results obtained an average of 0.61 in the medium category. The percentage increase in analytical skills on differentiating indicators is 66%, organizing indicators is 67%, and indicators of attributing are 51%.]]>

<![CDATA[This research aims to identify students' misconceptions on redox reaction material using the Four Tiers Diagnostics Test. The four tiers/stages are selecting answer, affirmation of the chosen answer, selecting reason of the chosen answer, and the affirmation of the selected reason. The diagnostic was carried out at SMAN (senior high school) 5 Bengkulu. The trial of the diagnostic test was conducted to students of class X MIPA 3 and the misconception diagnostic was conducted to students of X MIPA 2. The results show that the percentage of student misconceptions regarding the redox reaction material was 35% (medium category), while 40% of students understand the concept, and 25% of students do not understand the concept. The highest misconception occurs in the sub-concept of reduction and oxidation reactions (42%), follows by dispropornation and conpropornation reactions, (38%), oxidizing-reducing agents (37%), change in oxidation number from element to compound (24 %).]]>

<![CDATA[The subject of Chemistry is still relatively unfamiliar among junior high school students because it is still part of the broader Science subject taught at that level. This is also the case at SMPN 28 Bengkulu Utara, where students are still unfamiliar with chemistry. To introduce chemistry and create a positive impression of the subject among students at SMPN 28 Bengkulu Utara, an outreach activity was conducted focusing on interesting chemical phenomena — in this case, the phenomenon of quantum fluorescence.During the activity, explanations were given about the meaning of fluorescence, the causes behind it, and its applications in everyday life. The outreach activity also included demonstrations of the fluorescence phenomenon. Participants engaged in the event enthusiastically, as seen through the students' active participation. This activity is expected to help participants become more familiar with chemistry, a subject that has long been considered difficult, intimidating, and abstract. Keywords: fluorescence; chemistry; carbon quantum dots; light]]>

<![CDATA[This study aims to develop interactive learning media on the topic of complex reaction kinetics as an effort to stimulate students' systematic thinking skills. This type of research is development research using the ADDIE model. The test subjects in this study were students of the Chemistry Education Study Program who participated in the Chemistry Kinetics course in the 2022/2023 academic year. The data collection techniques in this study included feasibility data from the developed media based on expert validation of the media and material, as well as responses from students participating in the course regarding the developed media. The instruments used in this study were a questionnaire on the needs of course participants, a validation sheet, and a student response questionnaire. The results showed that the interactive learning media developed was deemed very feasible from the perspective of media and material validation, with average percentages for media and material validation of 92.5% and 93.75%, respectively. The results of the response test of students taking the Chemical Kinetics course to the interactive media developed showed an average score percentage of 86.6% and was in the very good category. The responses of the students also showed that the media developed could stimulate students' systematic thinking skills in the topic of complex reaction kinetics.]]>
