<![CDATA[This study aims to develop LKPD based on a scientific approach to the colloid concept for the practice of making green mussel shell crackers. This type of research was conducted using the Four-D model which was adapted from Thiagarajan which consisted of four stages: define, design, development, and disseminate. However, this research is limited only to the development stage. The LKPD eligibility criteria developed were reviewed from several aspects, namely the feasibility aspect of the content, the presentation feasibility aspect, the language aspect, the graphic aspect, the teacher and student responses. The product has been validated and continued with a limited trial phase was carried out on 16 high school/MA chemistry teachers in the Jabodetabek area and 36 students in class XII science at SMAN 4 Tangerang City. Data were collected using a validation questionnaire which was prepared using the Guttman scale and the teacher and student response sheets were compiled using a Likert scale. The results of the limited trial through the teacher's response questionnaire to the LKPD developed were 86%; and the results of the student questionnaire of 83.5% which are included in the very good category and are suitable for use in learning the colloid concept. ]]>

<![CDATA[This study aims to decide the influence of the Learning Cycle 6 Phase - Think Pair Share learning model on knowledge results and student retention on chemical equilibrium material. The research design was a quasi-experimental research design without a pretest (posttest-only control group design). All students of class XI MAN 1 Kota Malang were used as the population in this study. The sample selection was carried out using the cluster random sampling technique and 2 research groups were acquired. Class XI MIPA 6 was selected as the experimental class using the Learning Cycle 6 Phase - Think Pair Share learning model while class XI MIPA 5 was selected as the control class using the Learning Cycle 6 Phase. The number of students in class XI MIPA 5 was 36 students, while the amount of students in class XI MIPA 6 was 34 students. The measurement instrument used is a test. The test was carried out after being given treatment to measure students' skills to recognize the concept of chemical equilibrium. In addition, there is a retention test that is held 1 week and 1 month after students study chemical equilibrium material without prior notification. Test the hypothesis to determine whether there was a substantial difference in education outcomes and retention between schoolchildren taught by the 6-Phase Learning Cycle - Think Pair Share learning model and students taught with the 6-Phase Learning Cycle model in chemical equilibrium material with the Independent Sample T-Test. The data analysis technique used consisted of preliminary analysis consisting of a normality test and homogeneity test and analysis of results consisting of hypothesis testing. The outcomes of the Independent Sample T Test showed a likelihood worth of fewer than 0.05 which indicated that there was a substantial difference between the knowledge outcomes of the experimental group and the control group. The probability values of retention tests I and II are also smaller than 0.05. This shows that there is a substantial difference amongst the retention test of the experimental group and the control group on retention tests I and II. The outcomes of this research show that the midpoint knowledge outcomes in the experimental group are higher than the midpoint knowledge outcomes in the control group, namely 77 in the experimental class and 71 in the control class. This proves that the Learning Cycle 6 Phase - Think Pair Share learning model has an effect on student learning outcomes of MAN 1 Kota Malang on chemical equilibrium material. This model also affects student retention.]]>

The design of this study used the one-group-pretest-posttest experimental method. The target of this research is online learning using Hydrocarbon Adventures media games conducted by 27 grade XI students of Senior High School 1 Sampang. The students will be given a pretest before using the game and post test after using it. After that, students will be given questionnaire for the learning using online learning media. The results showed that student learning outcomes after using the learning media Hydrocarbon Adventures game had increased with classical completeness for values reaching 92.59%, and an increase in student learning outcomes at an average pretest value of 44.19 into an average post test score amounting to 83.41. Student responses about game media were obtained 79.2%. Based on these results, it was concluded that the Hydrocarbon Adventures learning media on the material of hydrocarbon compounds through online learning during the covid-19 pandemic can improve student learning outcomes.The purpose of this study was to determine the application of the game Hydrocarbon Adventures as an online learning medium for hydrocarbon compounds in the covid-19 pandemic.

<![CDATA[This study aims to see the effect of using Chemdroid media on students’ self-efficacy in a thermochemistry topic. Chemdroid is Chemistry on Android. Self-efficacy is related to students’ beliefs in activities in the classroom. This type of research is quasi-experimental using post-test only control group design. In this study, two different classes were used which were declared to be normalyy distributed and homogeneous. The first class is the control class (CC-Class) which conducts conventional learning media as usual. The second class is the experimental class (EC-Class) which uses Chemdroid media for thermochemistry topic as a learning media in the classroom. Both classes have the same learning time, teacher and learning model. The instrument used in this study is a self-efficacy questionnaire that has been developed in previous studies but has been adapted to current research. The statement items used in this measuring instrument are 22 statements with 6 aspects. The test used is the Mann Whitney with the help os the SPSS program. The result of the analysis state that the significance is smaller than level of conficence. This proves that there is a significant difference with the use of Chemdroid media for a thermochemistry topic on the self-efficacy of the control class and experimental class students.]]>
