<![CDATA[This paper reports ZnPt bimetallic nanoparticles (ZnPtBNs) synthesis through the liquid phase deposition (LPD) of of Zn(NO3)2.6H2O onto the indium-titanium oxide (ITO) substrates at various concentrations. The Effects of growth solution, the morphology, structural, and sheet resistance were studied. After preparation, the materials were characterized by using field emission electron microscopy (FESEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and Four Point Probe (FPP) measurement by using Keithley 2401 source-meter. By inserting a growth solution into the ITO substrate the ZnPtBNs was successfully in-situ prepared. The synthesized ZnPtBNs exhibited homogeneous, fibrous at the (111) orientation with an average diameter of 100-700 nm. The atomic ratio of Zn:Pt and sheet resistance of ZnPtBNs decreased with the increase of Zn(NO3)2.6H2O concentration. The optimal elemental composition of the sample was at a ratio of Zn:Pt (1:25) obtained at 0.467 mM of Zn(NO3)2.6H2O. It showed the smallest sheet resistance (13.41 ?) which was 38% lower than the ITO sheet resistance (18.44 ?).]]>

<![CDATA[Abstract. This research is based on existing problems, namely the absence of teaching materials that can support the implementation of the practicum and plus the learning process carried out during the covid-19 pandemic is learning at home or also called online learning, where students are instructed to study at home with use cell phone. This causes students to have difficulty understanding some chemical concepts. The purpose of this research is to produce a chemistry practicum manual based on learning cycle 5E for class XI SMAN 1 X Koto Diatas that can be used by students in carrying out practical activities at school and at home. This study uses a type of development research using a 4-D development model. The results showed that the validity of this 5E learning cycle-based chemistry practicum manual obtained a percentage of 96.00% with very valid criteria and the practicality results of this 5E learning cycle-based chemistry practicum manual obtained a percentage of 86.60% with very practical criteria. With this, it can be concluded that the chemistry practicum manual based on the 5E learning cycle that is designed is valid and can be used in the process of implementing the practicum.Keywords: Practicum Manual, Learning Cycle 5E, Validity and Practicality]]>

<![CDATA[This study aimed to evaluate the validity and practicality of a Guided Inquiry-Based Chemistry E-module for 11th-grade students at SMAN 1 Sijunjung. The study was conducted using a Research and Development (R&D) approach with the 4-D model (define, design, develop, and disseminate), and only the define, design, and develop stages were carried out. During the define stage, the learning conditions and instructional requirements were understood, while the design stage involved preparing the Chemistry E-module. In the develop stage, the validity and practicality of the E-module prototype were tested. The results of the study show that the Guided Inquiry-Based Chemistry E-module met standards with regard to its construction validity, as evidenced by a result of 94.4%. The module was also found to be highly practical based on student perception, with 86.4% of students indicating that the E-module was useful in the classroom. Overall, the findings suggest that the developed Guided Inquiry-Based Chemistry E-module can serve as an effective learning resource for students.]]>

<![CDATA[This study addresses the insufficiency of teaching materials in the learning process and its negative impact on students' comprehension of provided material. To alleviate this issue, student worksheets based on Learning Cycle 5E were developed to be used as a learning resource for 10th-grade students studying stoichiometry at State Senior High School (SMAN) 1 X Koto Singkarak. The aim of this research was to create a valid and practical Student worksheet based on Learning Cycle 5E. Development research with the 4-D development model (define, design, development, and disseminate) was employed, with the first three stages executed. The define stage was conducted to identify the school's conditions and problems, while the design stage was used to create the initial student worksheet based on Learning Cycle 5E for stoichiometry material. The develop stage was carried out to refine the worksheet. Data were gathered using validation sheets and practicality questionnaires filled out by two chemistry lecturers, one chemistry teacher, and 10th-grade students of SMAN 1 X Koto Singkarak. Data analysis was conducted using a quantitative descriptive method. Results indicated that the Student worksheet based on Learning Cycle 5E met the valid criteria with a validation score of 91.37% and the practical criteria with a student response questionnaire score of 82.09%. Thus, the worksheet can be used as a learning resource.]]>

<![CDATA[This research is motivated by students who do not understand chemistry lessons, especially in explaining formulas and calculations. Even though the learning methods and models used by teachers are different so that students have a "mindset" that learning chemistry is a difficult subject to understand. Another problem experienced by the teacher during learning, only the teacher is actively involved during learning while students are more dominant in listening to the teacher's explanation. The purpose of this study was to analyze and find out the Science Process Skills (SPS) of 11th grade science students at SMAN 1 Pulau Punjung. This research method is qualitative (descriptive). The subject of this research was the class of Stage F.2 which consisted of 27 students. Data collection techniques in this study were observation techniques, interview questionnaires, SPS documentation and questionnaires. The data obtained relates to the science process skills of students. Furthermore, researchers used data analysis techniques, namely the theory of Miles and Huberman which included data reduction, data presentation, and data verification and drawing conclusions, then the data was validated using the triangulation method. Based on the research that has been done, it can be interpreted that the results of the SPS analysis of Phase F.2 students of SMAN 1 Pulau Punjung on the observation indicator with a proportion of 89% and the experimental design indicator with a proportion of 82% both have very good categories. Then a classification indicator with a proportion of 77% and a predictive indicator with a proportion of 68% both have good categories. Then for the hypothesis delivery indicator with a percentage of 58% it is categorized as enough while for the hypothesis preparation indicator it has a proportion of 39% in the not enough category.]]>
