Learning about diffraction and light interference requires media that represent the events. Cognitive structures can represent the quality of students' understanding. Learning Physics is easier to understand through direct experience in the form of practicum. Abstract Physics concepts will be easier to learn with the appropriate visualization. One of the virtual practicums' media uses PhET virtual simulations to improve students' cognitive structure is measured using concept map questions and supported by description questions. The purpose of this research is to increase the cognitive structure of students by using PhET. This research is quantitative research and the experimental design used the experiment method. There are three groups in the experiment, that is a virtual simulation, a real practicum as an experiment class, and a control class. The results of the one-way ANOVA test on the concept map questions showed a significance value (p) 0.05, meaning that there were differences in cognitive structure between groups. The significance value (p) between the virtual simulation group and the real practicum group was 0.014, while the significance value between the virtual simulation group and the control class was 0.00, meaning that there was a significant difference in learning effectiveness between groups. Based on the data of the research concluded that physics learning assisted by virtual simulations can develop students' cognitive structures on the concepts of diffraction and light interference.

Abstract

Due to their properties, ZnO nanoparticles have recently been used as an additive material in active food packaging. ZnO has a wide band gap of about 3.37 eV, making it effectively used under UV light. However, ZnO nanoparticles are not effectively used under visible light. This study successfully synthesized ZnO-Chitosan-Citronella Essential Oil hybrid nanoparticles using sol-gel methods. Adding chitosan and citronella essential oil will affect nanoparticles' structural and optical properties.  The structural, morphological, and optical properties of characterized hybrid nanoparticles were studied using X-ray diffraction (XRD) and FTIR, scanning electron microscope (SEM), energy dispersive X-ray (EDX), and UV-Vis spectroscopy. From XRD, it was obtained that the ZnO nanoparticles produced have a hexagonal wurtzite crystal structure with angles of 2q = 31.76°, 34.48°, 36.30° which are crystal planes with orientations (100), (002), and (101), as well as several other peaks for planes (102), (110), (103), (200) and (112) with a crystallinity index value of 86.5390%, and crystallite size of 8.87nm and 7.5335 nm. From FTIR Characterization, Zn=O functional groups were also obtained at wave numbers 657 and 475 cm-1. The morphology of ZnO nanoparticles from SEM spectroscopy shows a spherical shape with agglomeration, and the composition of the components Zn, O, and N elements is found, which come from chitosan materials. Furthermore, from the UV-Vis spectroscopy characterization, it was obtained that the absorption occurred in the 380-600 nm region with a band gap energy of 3.25 eV (using the tauc plot method), which was slightly different from the empirical results of 3.30 eV. The results show potential future studies of hybrid nanoparticles, such as additive materials in active food packaging.

Abstract

This research aims to develop a set of e-diagnostic four-tier tests on Momentum topics that can be utilized to identify students' learning difficulties and misconceptions. The tests are to be valid, reliable, and effective. This research and development (R&D) project employed the 4-D model, which encompasses the following four stages: Define, Design, Develop, and Disseminate. The Define stage entailed a comprehensive needs analysis and identification of critical issues, while the Design stage encompassed the formulation of e-diagnostic four-tier test grids and instruments. The development stage comprised the implementation of development activities, expert validation, product testing, and the final assembly of the product. The dissemination stage involved the publication of the results of the development of the e-diagnostic four-tier test. The test was constructed in the form of a five-option multiple-choice test. Each question comprises four tiers or levels, ranging from questions, confidence levels, and reasons to the subsequent confidence level. The data collection instrument includes an assessment sheet for product validity, scoring guidelines, and a Likert scale for determining the practicality of product use. The data analysis technique employs the following formulas: (1) Aiken's V for testing validity, (2) Cronbach Alpha for determining reliability, (3) probability of answering correctly to ascertain the level of difficulty of the items, (4) differentiating power to determine the differentiating power, and (5) percentage to measure the level of misconception. The outcome of this research is a series of four-level diagnostic multiple-choice tests accompanied by explanatory material designed to address potential misconceptions. The tests have been evaluated rigorously for validity, item analysis, practicality, and effectiveness.

Abstract

Dancers’ makeup in a performance is an attraction for the community of connoisseurs and observers of the Ebeg. The Mega Laras group in Tanjunganom, Rakit, Banjarnegara was plagued by problems with the makeup of its performers in staging performances, caused by the lack of knowledge and skills of the dancers and makeup artists. With full support from the village government and all group members to conserve Ebeg as an Indonesian cultural heritage, Universitas Negeri Semarang through its community service team provided a solution through facilitation-based action learning model training. The purpose of this activity was to improve the makeup skills of the group members, with main stages of implementation of preparation, training, and result analysis. The preparation included coordinating with partners about the place and time of the activity, and team coordination regarding technical implementation. The training phase included planning, workshop, and mentoring. During the training, a set of tools and makeup materials were distributed to partner. Analysis of the overall activity showed that 80% of participants demonstrated significant skill improvement after the training. The community service activity supports Sustainable Development Goal (SDGs) 4, namely Quality Education, for providing lifelong learning opportunities for the traditional arts practitioners.

Abstract

Adanya tuntutan pelibatan teknologi dalam proses pembelajaran menjadi tantangan yang harus dihadapi guru. Penyelidikan ilmiah dalam pembelajaran fisika menjadi sangat penting, namun sayangnya tidak semua sekolah memiliki fasilitas laboratorium yang memadai. Agar pembelajaran tetap terlaksana dengan baik, keadaan tersebut memaksa guru untuk aktif dan kreatif menciptakan praktikum yang inovatif dengan sumber daya yang ada. Keadaan ini dapat diatasi dengan praktikum digital, yang salah satunya dapat dilakukan dengan memanfaatkan smartphone masing-masing peserta didik. Praktikum fisika dengan smartphone dapat menjadi inovasi praktikum digital karena guru dapat merancang sendiri jenis percobaannya. Kegiatan pengabdian kepada masyarakat ini dilaksanakan dengan metode Community Based Participatory Research (CBPR) pada MGMP Fisika SMA/MA Kabupaten Semarang Jawa Tengah. Kegiatan berupa pelatihan terkait pengenalan set alat praktikum digital, membaca data, mengolah, memvisualisasikan dalam grafik, dan menginterpretasikannya. Aplikasi digital yang digunakan adalah Arduino Science Journal yang dapat dioperasikan dengan memanfaatkan sensor yang telah tersedia pada smartphone android. Alat praktikum yang dihasilkan berupa satu set alat papan luncur yang dapat divariasikan sudut kemiringannya, dilengkapi dengan alat peluncur berupa mobil mainan yang dimodifikasi dengan holder HP. Alat ini dapat digunakan untuk mengukur percepatan, kemudian data digital dapat diolah ke dalam besaran fisis lain, seperti kecepatan dan posisi setiap saat. Pada akhir kegiatan, set alat praktikum disumbangkan kepada MGMP sebagai percontohan agar dapat diadopsi oleh pihak sekolah untuk memenuhi kebutuhan fasilitas laboratorium.
