Abstract

Limbah organik maupun anorganik seperti daun, kertas, sayuran, buah-buahan, styrofoam,dan plastik dapat digunakan sebagai sesuatu yang bermanfaat. Pada penelitian sebelumnya, sampah yang sering digunakan antara lain sampah styrofoam, sekam padi, kertas, plastik,dan serbuk kayu dapat dijadikan sebagai alternatif bahan bangunan, dan telah teruji kelebihannya, baik secara fisik maupun mekanik. Pada penelitian ini memanfaatkan sampah halaman yang kadang mengganggu dan tidak terkelola dengan baik, salah satunya adalah daun jambu. Komposit sampah daun jambu dapat digunakan sebagai bahan alternatif furniture seperti papan partikel yang berfungsi sebagai penyangga keyboard komputer, rak sepatu dan lain-lain. Daun jambu yang kering dibuat sebagai komposit dengan polimer alami getah pohon karet. Komposit dibuat dengan cara pencampuran sederhana (simple mixing) dengan perbandingan massa daun jambu dan getah karet masing–masing 5:1, 5:2, 5:3, 5:4 , 5:5 dan 5:6. Sampah daun kering yang sudah dihancurkan kemudian dipress dengan mesin pengepress  pada posisi berat 5 ton tekanan 39,81 MPa dan suhu kamar. Komposisi maksimum dari pencampuran komposit dengan polimer getah karet dapat diuji dengan melakukan uji kekuatan tekan. Kekuatan tekan yang paling baik menunjukkan bahwa komposit daun jambu dengan polimer getah karet layak untuk dijadikan sebagai bahan alternatif furniture pengganti kayu.

Abstract

Penentuan kecepatan sudut dalam motor listrik diperlukan suatu alat yang bisa mengkonkretkan konsep gaya Lorentz menjadi energi mekanik, sehingga diharapkan analisis masalah dan konsep gaya Lorentz  jadi lebih mudah. Kecepatan sudut motor listrik manual diperoleh 17,33 rad/s pada variasi lilitan 280, 330 dan 380 yang memenuhi persamaan  y = 0.054x - 0.657 dan R² = 0.842 artinya 84.2% dari seluruh variasi jumlah lilitan dapat diterangkan oleh regresi, dan 5,8 % lagi yang tidak dapat diterangkan model yang digunakan termasuk ketidaktelitian dalam pengamatan. Sedangkan 19,15 rad/s kecepatan sudut pada variasi  tegangan dengan y= -1.015x + 10.00 dan R2 0,980 artinya 98 % kontribusi variasi tegangan 6, 9 dan 12 volt terhadap besarnya kecepatan sudut motor listrik manual. Sehingga dua variabel yang di variasi ini memenuhi kebutuhan pada penentuan kecepatan sudut motor listrik, semakin besar kecepatan sudut yang dihasilkan semakin besar lilitan dan tegangan yang dibutuhkan.

Abstract

Using the Sky Map application in astronomy learning of celestial coordinates is intended to analyze students' level of understanding of concepts and digital literacy. Students' understanding of concepts and digital literacy was measured through tests and questionnaires. The research was focused on students who took astronomy courses in the physics department of Semarang State University, totaling 40 students. The type of research used is quantitative research. The research design carried out was pre-experimentation with one group pretest-posttest. There are two variables used, i.e. the use of Sky Map application media as the independent variable, and the improvement of the understanding of the student concept as the dependent variable. The analysis using the Wilcoxon signed rank test showed a significant increase in students' conceptual understanding after using Sky Map application media in learning with an N-Gain of 0.21, and digital literacy in the use of Sky Map application media has attained 83.47% (excellent). Therefore, it can be concluded that the use of Sky Map application media in celestial coordinates can help students understand the concept of the material as well as increase their digital literacy skills.

Abstract

The purpose of this research is to determine the tidal flood disasters mitigation understanding and environmental awareness, as well as to measure the achievement of learning outcomes through the implementation of simulation video assisted problem-based learning. This research used pre-experimental design with one-group pretest-posttest, with the sample is seventh-grade students at Barunawati Junior High School Semarang. The instruments used are multiple-choice questions and Likert scale questionnaire. Rasch model was used to measure the instrument validity and to investigate the attitude scale of environmental awareness due to the learning model implementation, while N-gain test and t-test was used for cognitive analysis of climate change and tidal flood disaster mitigation materials. The knowledge of climate change and tidal flood disaster mitigation increased with N-gain of 0.40 and 0.37, respectively, while the results of t-test for learning outcomes in climate change and tidal flood disaster mitigation showed a significant increase in cognitive learning outcomes, since the video simulation-learning encouraged students to be more active and responsive. Furthermore, the analysis of the attitude scale questionnaire showed an improvement with person measure value from 0.04 (pretest) to 0.84 (posttest). It can be concluded the simulation video assisted problem-based learning model can increase climate change and tidal flood disaster mitigation knowledge, and environmental awareness of students

Abstract

Reading is an important activity that must be present in the science learning process, especially reading with meaningful activities, one of which is critical argumentation reading activity. Reading is very closely related to student motivation while reading. This motivation plays an important role in supporting the success of reading goals. So far, research related to students' reading motivation has rarely been carried out, especially for critical argumentation reading activities. Most of the research was conducted at the elementary and secondary school levels. Therefore, this research will be conducted with the aim of analyzing students' motivation while reading using critical argumentation activities. This study involved 83 science teacher candidate students. In practice, students were divided into three classes, namely group experimental class (N = 29), individual experimental class (N = 29), and control class (N = 25). The research was conducted using the think aloud protocol method, in which students were asked questions while reading the text, and recorded all the answers orally. The results showed that students' motivation during reading as part of a self-regulation strategy showed better results when students read using the critical argumentation reading model. In addition, students are able to carry out self-regulation strategies from a better motivational aspect if reading activities are carried out in groups.

Abstract

This study investigates the impact of cashless payment technologies, specifically e-toll and Garda Total Objek (GTO), on customer satisfaction and travel efficiency on the Tangerang-Merak Toll Road. The research demonstrates that the implementation of these technologies significantly enhances travel time efficiency and overall user satisfaction, providing a more seamless and convenient toll payment experience. Despite these positive outcomes, the study identifies several technical challenges that hinder optimal performance. Notably, there is an 18% transaction failure rate, primarily caused by malfunctions in card reader devices and server disruptions, which negatively affect the customer experience. In addition to technological reliability, the quality of service delivered by field staff and the degree of customer loyalty emerge as critical factors influencing sustained use of the digital payment system and overall satisfaction levels.The study underscores the importance of time efficiency and customer loyalty as key drivers for improving service quality and encouraging the widespread adoption of cashless systems. To address these challenges, the study recommends enhancing the reliability of payment devices and network infrastructure through regular maintenance and upgrades. Furthermore, the adoption of Multi-Lane Free Flow (MLFF) technology is suggested to allow toll transactions without stopping, thereby reducing traffic congestion and waiting times at toll plazas. Continuous staff training is essential to improve service response and technical troubleshooting. Additionally, customer loyalty programs offering incentives like discounts and rewards could increase user engagement. The study also emphasizes the need for increased public education on cashless payment systems and their features to minimize resistance and misunderstandings. Finally, ongoing monitoring and evaluation based on user feedback are critical for promptly addressing issues and sustainably improving customer satisfaction.
