Abstract

In precast concrete, a connection is needed to unite the components so that they become a whole unified structure. This study aims to determine the reinforcement strength and length of reinforcement in precast concrete connections. To paste reinforcement into precast concrete, giving additional material in the form of grouting which is called sika grout 215 and functions as an adhesive is necessary. Pullout testing is carried out in the laboratory, and its simulation by modeling uses the finite element method based software. This research is divided into 2 phases. The first phase is making specimen to examine the bond strength between the concrete and reinforcement that has been given sika grout 215. So monolithic specimen is made as a comparison. The result of the bond strength of the monolithic test specimen is 6.24 MPa, and the sika grout 215 category is 6.52 MPa. From the experimental results in the laboratory with modeling, it is obtained the bond strength ratio of 0.94. The length of development (ld) based on the results of the testing phase I of 200 mm. The second phase is examining the damage pattern due to the stress that occurred. Specimens are made into 4 categories, namely modeling developments with the length of 120 mm (<40% ld), with the length of 160 mm (<20% ld), with length of 200 mm (= ld), and with the length of 260 mm(> 30% ld) both for monoliths and sika grout 215. The damage pattern, which is in the form of yielding and breaking reinforcement as the result of the pullout experiment in the laboratory shows not much different from the result of simulation using the software.

Abstract

Children with special needs are children who require special services that are different from other children in their educational curriculum. Deaf (hearing impaired) is a general term used to describe people who suffer from hearing loss or impairment caused by damaged or non-functioning hearing aids. Good behavior is a human action or activity that leads in a positive direction according to personal experience. The efforts made by teachers are (1) by providing knowledge and understanding using sign language, (2) by providing a sense of empathy for children through sign language instructions, (3) providing examples of good and appropriate behavior through sign language or body language so that they are easy to understand. understood by children with special needs such as the deaf. The reasons for this research are 1). What is your learning method for applying good behavior to Deaf children? 2.) How do you respond if a child has difficulty accepting material related to good behavior? 3). From the results of the implementation of good behavior at school, is there a particular evaluation and what is done by teachers to encourage enthusiasm for learning in children? To find out how teachers try to implement good behavior at SLB Negeri 5 Bengkulu City, researchers took a qualitative approach using data source methods obtained from three types of data sources, namely, data collection techniques in the form of observation, interviews and documentation.

Abstract

Kesulitan dalam membaca, menulis, dan berhitung (calistung) merupakan tantangan utama dalam pendidikan dasar yang dapat memengaruhi perkembangan akademik siswa. Penelitian ini bertujuan untuk mengidentifikasi faktor penyebab kesulitan calistung dan menawarkan solusi efektif. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan observasi dan wawancara. Hasil penelitian menunjukkan bahwa 60% siswa mengalami kesulitan membaca, 50% kesulitan menulis, dan 70% kesulitan berhitung. Faktor utama meliputi metode pembelajaran yang kurang variatif, minimnya kebiasaan belajar di rumah, serta kurangnya media pembelajaran interaktif. Solusi yang direkomendasikan mencakup pembelajaran interaktif, keterlibatan orang tua, penggunaan media inovatif, serta peningkatan kompetensi guru. Dengan strategi ini, diharapkan kesulitan calistung dapat dikurangi, mempersiapkan siswa untuk jenjang pendidikan lebih tinggi.

Abstract

This study aims to evaluate the effectiveness of using the Quizizzz application as a digital-based learning medium to enhance students' technological literacy at MI Asy-Syifa. The research is motivated by the growing importance of digital literacy in the technology-driven era, particularly in supporting the Merdeka Curriculum, which emphasizes flexibility and the integration of technology in education. A qualitative method was employed, utilizing training sessions that included lectures, demonstrations, and Q&A, involving 39 third-grade students. The findings indicate that Quizizzz enhances student motivation through gamification, though challenges such as limited technological infrastructure and students' low initial understanding were observed. The training successfully introduced Quizizzz features and educated students on the ethical use of technology. The study concludes that Quizizzz has significant potential as an interactive and engaging learning assessment tool, but continuous training and infrastructure support are needed for optimal implementation. This initiative also contributes to the application of the Merdeka Curriculum by leveraging technology to create a more dynamic and effective learning process.
