Pengaruh Ketebalan Lapisan Tipis ZnO terhadap Kinerja Sel Surya Perovskit Fleksibel

Putri Ekarani — 2023-11-18

Photoelectrode preparation that requires high heating temperatures will hinder the future development of PSCs on flexible plastic substrates. Therefore, ZnO is a viable alternative for flexible PSCs because it can be processed at low temperatures. This research focuses on the influence of ZnO photoelectrode layer thickness on the optical properties and performance of PSCs. The transmittance of ZnO thin films was found to be more than 50% in each sample. In addition, the bandgap obtained ranged from 3.12 to 3.20 eV. The efficiency results are 0.90×10^-5% at a thickness of 10 µm, 1.09×10^-5% at a thickness of 8 µm, 2.68×10^-5% at a thickness of 6 µm, and the best efficiency is 4.31×10^-5% at 4 µm thickness. Based on the results of research that has been carried out, reducing the thickness of the ZnO photoelectrode layer can increase the transmittance and efficiency of solar cells so that solar cell performance increases.

Penentuan Ukuran Butir (Particle Size) Cu dan Ni pada Lapisan Cu/Ni Menggunakan Metode Scherrer Termodifikasi

Rizka Nuzul Islamiyati — 2023-11-18

The Cu/Ni layer is a layer that can be used as a material for low temperature sensors. The coating can be made by means of electroplating. Electroplating has limitations in controlling the number and size of metal particles. Therefore, the purpose of this study was to determine the grain size of Cu and Ni in electroplated Cu/Ni layers at varying voltages from 6 to 8 volts using the modified Scherrer method and to analyze the effect of stress on grain size. The method used in this research is descriptive method using a quantitative approach. The results showed that the grain size of the Cu substrate was D= (0.5071 ± 0.06) nm. As for the Ni layer, stress affects grain size. A voltage of 7 volts can produce the largest grain size of 0.776059 nm.

Ulya Ghifrani Rahmania — 2023-11-18

Gedogan is one of the arts that can be found in several places in Banyuwangi. Gedogan is part of the culture of pounding rice from the Osing Banyuwangi community. This is a musical art that is played by women using a mortar and pestle that are smacked against each other. This study aims to analyze the sounds that appear in the Gedogan. Data were collected by interview, observation, and documentation. Data were analyzed using software (software) Visual Analyzer (VA) which can detect sounds along with the intensity and frequency of incoming sounds. This research illustrates that the sound in Gedogan depends on the material of the mortar, its size, position, and the point of impact. This can be seen from different measured sound frequencies. The Gedogan Rumah Wisata Osing group distinguishes sounds with the techniques of othek 1, othek 2, and othek 3. The frequency produced in the games of the Gedogan Rumah Wisata Osing group ranges from 320-1120 Hz This study is expected that this research will be a way to preserve culture by introducing and integrating related learning.

Efektivitas Penggunaan Media Pembelajaran Edpuzzle Berbasis Video Terhadap Hasil Belajar Peserta Didik pada Materi Suhu dan Pemuaian

Muhammad Syarif Hidayat — 2023-11-18

After Covid 19, computer-based distance learning was opened, but based on a preliminary study in one of the Public High Schools in the Kuningan Regency area, it obtained 710 out of a maximum score of 1600 (low category). The research method uses a quasi experiment with a Pretest-Posttest Control Group Design approach. This research was conducted in January - February 2023 at Public High School. The research population was all class XI IPA of SMA Negeri, consisting of 6 classes with 213 students. The research sample was taken using a random cluster sampling technique as many as 2 classes out of 6 classes, namely class XI IPA 1 as the intervention group and Class XI IPA 2 as the control group. Data analysis techniques used the Chi Square test, Fisher's test, and T-test. The results of the calculation of the hypothesis test using the paired sample t-test with a significance level (α = 0.05) obtained tcount>t_table, namely 3,495>2,030. it can be concluded that there are differences in the effect of using video-based Edpuzzle learning media on student learning outcomes at Public High School.

E-Module Gerak Lurus: Peluang Pengembangan Keterampilan Proses Sains dan Keterampilan Bernalar

Sulur — 2023-11-18

This research aims to develop an e-module based on Predict-Observe-Explain (POE) equipped with questions that refer to the Minimum Competency Assessment (AKM) for high school students on the topic of linear motion that is valid, readable, and practical. This research uses a Research and Development (R&D) research design with a 4D model, namely Define, Design, Develop, and Disseminate. This research produces an e-module for the topic of linear motion in the form of an application that can be used on Android-based devices. E-module has material presented with POE stages in each learning activity, which has the opportunity to improve students' science process skills. Moreover, the e-module is also equipped with AKM questions on the same topic, linear motion, which is expected to improve students' reasoning skills. The results of this research show that the e-module developed is classified as very valid with a percentage of 95.6%. In addition, the e-module also has very good readability and practicality, with a percentage of 94.8%. Thus, the e-module can be used in learning the physics topic, linear motion, for high school students.

Pengembangan Majalah Fisika Pada Materi Usaha dan Energi Terintegrasi Islam

Mukhlis Rohmadi — 2023-11-18

Reading is one of the most important efforts in the learning process. Student learning outcomes, especially business and energy materials, are still low due to the low interest in reading/student literacy, so media is needed that can increase students' reading interest. The purpose of this research is the development of learning media in the form of physics magazines that Islamic Integrated. The development of Islamic integrated magazine media is proceeds using the ADDIE development model. The results showed the results of material expert assessment with a percentage of 72.2% (feasible), media expert assessment with a percentage of 84% (feasible), and interpretation expert assessment with a percentage of 73.3% (feasible). In the trial, students obtained a good and positive response, by obtaining an average percentage of 79.54% with good and decent criteria. From the data from the expert assessment, the learning media for Islamic integrated physics magazines developed is declared feasible and can be used as a learning medium in Business and Energy materials.

Analisis Bahan Ajar Fisika Kelas X Berdasarkan Pilar Education for Sustainable Development (ESD) dan Science, Technology, Engineering, Art, and Mathematics (STEAM)

Sri Wahyuni — 2023-11-18

This study aims to analyze the teaching materials for grade X physics from two important perspectives, namely the ESD (Education for Sustainable Development) pillar and the Science, Technology, Engineering, Art, and Mathematics (STEAM) approach. The research method uses descriptive qualitative research. The population in this study was teaching materials for grade X physics used by teachers in Rembang Regency. The research instrument was a checklist of analysis instruments based on indicators of the Education for Sustainable Development pillars and STEAM components to obtain data. The results of the study found that the teaching materials used had implemented the ESD and STEAM pillars with an average percentage of occurrence of 12% for the socio-cultural pillar, 36% for the environmental pillar, 16% for the economic pillar, 87% in the Science component, 50% in the technology component, 57% in the engineering component, 77% in art, and 40% in the mathematics component.
