Abstract

Innovation in floor plate methods has been developing nowadays, one of the methods is the precast method. However, this method cannot behave monolithically with other structures so that the deflection does not meet the permit. To overcome this problem then the half-slab plate innovation comes with a combination of precast and conventional method for the topping. This study discusses the ratio of half-slab and conventional floor plate capacity based on the thickness variation. The capacity analysis covers the bending moment, shear force, deflection and stress due to gravity loads. The total thickness of plate was 120 mm and 130 mm, with the three thickness variations which were the precast is thicker than the topping, the topping is thicker than the precast, and the topping is equal to the precast. The results show that the half-slab plate capacity is 8 to 20 times larger than the conventional plate, due to the lifting and shoring forces. In addition, the variations in the topping and precast thickness affect the value of half-slab capacity, which is the thicker the precast the greater the capacity. Adding thickness every 5 mm could increase the moment capacity by 1,58-7,14%, the shear capacity by 1,61-7,14%, the deflection by 1,69-2,08% and could decrease the normal voltage by 1,76%. So the good variation in the half-slab plate thickness is the plate with the precast thickness which is smaller than the topping thickness. From the two types of plates, plates with a thickness of 130 mm have the capacity 4 to 8 times larger than 120 mm. This is influenced by the lift point placement, shoring plots and a larger 130 mm plate width. Keywords: floor plate capacity, half-slab, thickness variation

Abstract

This study analyzes the critical thinking tendencies of students with physical disabilities in mathematics learning at SMA-LB Negeri 3 Yogyakarta using a Grounded Theory approach. A qualitative method was applied, with data collected through observations, interviews, and questionnaires. The results indicate that 80% of students exhibit positive critical thinking tendencies, while 20% face internal challenges such as shyness, lack of confidence, and difficulty in collaboration. The main factors influencing critical thinking tendencies include the role of teachers, student participation, and classroom conditions. Teachers who implement interactive learning strategies, such as discussions and cooperative learning, play a crucial role in motivating students. A comfortable learning environment and adequate facilities also support the development of students' critical thinking skills. This study concludes that interactive teaching strategies and a conducive learning atmosphere are key to fostering students' critical thinking tendencies.

Abstract

Paving block merupakan material perkerasan permukaan tanah yang dibuat dari campuran semen, agregat, dan air. Penelitian ini bertujuan untuk menganalisis karakteristik paving block dengan menggunakan HDPE dan Fly Ash sebagai bahan substitusi pasir, serta mengevaluasi kesesuaiannya terhadap SNI 03-0691-1996. Metode yang digunakan adalah metode eksperimental dengan benda uji berukuran 20 x 10 x 6 cm. Substitusi agregat halus dilakukan menggunakan campuran HDPE dan Fly Ash dengan variasi persentase sebesar 0%, 5%, 10%, 15% dan 20%. Pengujian meliputi pengujian kuat tekan, ketahanan aus, penyerapan air dan ketahanan natrium sulfat. Pengujian dilakukan pada umur 28 hari sesuai dengan ketentuan SNI 03-0691-1996. Hasil penelitian menunjukkan penggunaan HDPE dan Fly Ash pada proporsi tertentu mampu meningkatkan mutu paving block. Nilai kuat tekan tertinggi diperoleh pada variasi 15% sebesar 26,667 MPa. Seluruh variasi memenuhi mutu B untuk kuat tekan, ketahanan aus memenuhi mutu A, sedangkan penyerapan air menunjukkan mutu B dan C tergantung variasi.

Abstract

Abad ke-21 adalah abad digital. Komunikasi dilakukan melewati batas wilayah negara dengan menggunakan perangkat teknologi yang semakin canggih. Kemajuan teknologi tersebut dirasakan oleh berbagai industri dan manufaktur. Namun dari berbagai bidang yang ada, pendidikan adalah bidang yang paling merasakan dampak positif terhadap kemajuan teknologi dan informasi. Salah satu penerapan pembelajaran abad 21 adalah modul blended learning. Modul berbasis blended learning akan memberikan warna baru yang dapat dengan mudah dilakukan oleh siswa dengan bimbingan guru. Salah satu kelebihan modul blended learning yaitu bahan ajarnya memberikan pengalaman bagi peserta didik dalam belajar mandiri dengan melakukan intruksi-instruksi untuk melakukan tugas dengan bisa mengakses materi-materi secara online. Kegiatan ini bertujuan untuk melatih peserta dalam menyusun modul Blended Learning yang dapat digunakan pada pembelajaran. Peserta merupakan guru-guru SMKN 6 Kota Bekasi dan SMKN 1 Cikarang Barat sejumlah 45 orang. Peningkatan nilai dari pretest (62,22) ke posttest (69,33) menunjukkan pemahaman peserta mengenai penyusunan modul Blended Learning meningkat.
