ANALISIS DESKRIPTIF DALAM PENERAPAN PROJECT BASED LEARNING MELALUI PENDEKATAN TEACHING THE RIGHT LEVEL (TARL) PADA PEMBELAJARAN IPA KELAS 8 SMP

Rizmeia Nur Atmasari — 2024-05-01

This study examines the implementation of the Teaching at the Right Level (TaRL) approach within Project Based Learning (PjBL) in science classes at SMP Negeri 1 Malang for eighth graders, focusing on its impact on learning styles and student learning outcomes. The background of this study is based on differences in abilities and learning styles of students that require a more individualized learning approach. The research used a qualitative descriptive analysis method to observe and document the learning processes and outcomes. Data were collected through interviews, observations, and document studies. The results indicate that the implementation of TaRL within PjBL helps students better understand the material and increases their motivation to learn. Students showed significant improvements in concept understanding and active participation in learning. This research recommends the wider application of the TaRL approach in the curriculum for subjects that require deep conceptual understanding.

Students' active participation during the learning process is one of the main keys to success in education. Therefore, learning media that are interesting and appropriate to student characteristics are needed to encourage active student involvement. The snakes and ladders game can be used as a learning medium because it suits the characteristics of elementary school students, who tend to enjoy playing, moving, working in groups, and demonstrating something directly. This approach centers learning on students and encourages their active participation during learning activities. This research aims to analyze the activity of second-grade elementary school students using snakes and ladders media in lesson study-based mathematics learning. The research employs qualitative methods by analyzing data descriptively. The subjects of this research were 25 second-grade students at SDN Kauman 2 in Malang City. The data collection techniques used were interviews, observation, and documentation. Data analysis followed the Miles and Huberman model. The research results showed that the application of snakes and ladders as a learning medium significantly increased the activity of second-grade students at SDN Kauman 2, Malang City, from an initial activity percentage of 46% in the "Low Activity" category to 76% in the "High Activity" category. Therefore, it can be concluded that the use of snakes and ladders as a learning medium plays a significant role in encouraging students to be actively involved during the learning process.

PENGARUH KETEBALAN LAPISAN PDMS-H TERHADAP PERFORMA NANOGENERATOR ZNO NRS/ PDMS-H/ CU

Afiifatur Rachmah — 2024-05-01

In the past decade, piezoelectric nanogenerators have demonstrated relatively low power performance, necessitating advancements to enhance their efficiency. The performance improvement of piezoelectric nanogenerators can be achieved by incorporating conductive polymers into the nanogenerator layers. This study aims to investigate the effect of hydride-terminated polydimethylsiloxane (PDMS-H) layer thickness on the conductivity and performance of piezoelectric nanogenerators. The piezoelectric nanogenerators were fabricated by growing ZnO nanorods (ZnO NRs) on an ITO PET substrate using the hydrothermal method at 95°C. PDMS-H was applied over the ZnO NRs using the spin coating method with varying thicknesses, determined by spin coating speeds of 2000 rpm, 3000 rpm, 4000 rpm, and 5000 rpm. Subsequently, Cu was deposited onto the PDMS-H layer using the DC magnetron sputtering method, forming a single device. XRD patterns confirmed the successful growth of ZnO NRs with a hexagonal (wurtzite) crystal structure. SEM results showed that ZnO NRs had diameters ranging from 431 nm to 1038 nm. Additionally, UV-Vis characterization of ZnO NRs indicated a bandgap of 3.63 eV. FTIR characterization revealed absorption peaks for ZnO NRs in the region from 4000 to 400 cm^-1 and for PDMS-H in 838 cm^-1 and 3243 cm^-1. The electrical conductivity for each variation was4,98 x 10²Ω^-1cm^-1, 3,98 x 10² Ω^-1cm^-1, 1,37 x 10² Ω^-1cm^-1, and 0,05 x 10² Ω^-1cm^-1, with corresponding performance outputs of 732.9 µWatt, 270.3 µWatt, 170.7 µWatt, and 128.7 µWatt. The study results indicate that piezoelectric nanogenerators' electrical conductivity and performance are directly proportional to the PDMS-H layer thickness. As the PDMS-H layer becomes thicker, the conductivity and performance of the piezoelectric nanogenerators increase, and conversely, as the PDMS-H layer becomes thinner, the conductivity and performance decrease.

In this Merdeka Curriculum era, a learning model is needed that can increase students' activeness and understanding. Student-centered learning is expected to increase students' understanding and role in the learning process. Understanding concepts in physics science learning is very important to improve so as not to cause misunderstanding or misconceptions in the future. The material of object motion consists of several sub-materials, namely distance, displacement, velocity, speed, acceleration, and deceleration. The purpose of this study was to analyze the understanding of students regarding the concept of motion of objects in science learning as indicated by the acquisition of the percentage of students answering questions correctly using the method used is descriptive quantitative. The instrument used in this study was a multiple-choice question of 10 questions. Respondents who participated were 33 students of VII D class in SMPN 12 Malang. The results showed that overall the percentage of students who answered correctly was 62% and included in the high category. Students' understanding of the sub-materials of distance, displacement, and speed is in the high category. As for the sub-materials of speed, acceleration and deceleration are included in the medium category.

URGENSI PROGRAM RESITASI UNTUK PEMAHAMAN KONSEP MAHASISWA PADA MATERI KINEMATIKA 1 DIMENSI

Nabila Lailatul Mahmudah — 2024-05-29

This research aims to determine the level of urgency of the recitation program as an interactive medium in increasing students' conceptual understanding of 1-dimensional kinematics material. The program contains questions and feedback so that students can find out where they made mistakes after choosing an answer option. The research method used is a literature study with a qualitative descriptive approach. Research sources come from articles in previous journals related to 1-dimensional kinematics material and recitation programs. The research results show that there are still many students who do not know how to draw Uniform Linear Motion (GLB) and Uniformly Accelerated Linear Motion (GLBB) graphs correctly, the difference between velocity and speed, the difference between distance and displacement, and the concepts of GLB and GLBB. Another case study revealed that an effective way to increase understanding of physics concepts is by implementing a recitation program. Therefore, creating a recitation program is very urgent as a support in optimizing students' understanding of the concept of 1-dimensional kinematics.
