Abstract

ABSTRAKAnalisis kapasitas momen melalui uji kuat tekan pada sambungan blind mortise-tenon kayu jati dilakukan untuk mengevaluasi pengaruh variasi geometri tinggi tenon. Melalui metode eksperimental, sebanyak 20 spesimen berbentuk L dengan variasi tinggi tenon 25, 30, 35, dan 40 mm diuji menggunakan Compression Testing Machine pada sudut 45°. Hasil uji one-way ANOVA mengungkapkan bahwa penambahan tinggi tenon cenderung menurunkan ketahanan momen akibat penipisan dinding mortise, meskipun terjadi peningkatan kembali pada variasi 40 mm karena distribusi tegangan yang lebih merata. Kapasitas momen tertinggi dicapai oleh variasi 25 mm (257.798,83 Nmm), sementara nilai terendah berada pada variasi 35 mm (161.999,81 Nmm). Kegagalan struktural yang dominan teridentifikasi melalui pecahnya dinding mortise dan retak horizontalKata kunci: sambungan blind mortise-tenon, tinggi tenon, ketahanan momen ABSTRACTAn analysis of moment capacity through compression testing on blind mortise-tenon joints made of teak wood was conducted to evaluate the effect of variations in tenon height. Using an experimental method, 20 L-shaped specimens with tenon heights of 25, 30, 35, and 40 mm were tested using a compression testing machine at a 45º angle. The results of the one-way ANOVA revealed that increasing tenon height tends to reduce moment resistance due to the thinning of the mortise walls, although a slight increase was observed in the 40 mm variation due to a more even stress distribution. The highest moment capacity was achieved by the 25 mm variation (257,798.83 Nmm), while the lowest value was found in the 35 mm variation (161,999.81 Nmm). The dominant modes of structural failure were identified as mortise wall rupture and horizontal cracking.Keyword: blind mortise-tenon joint, tenon height, moment resistance

Abstract

According to BMKG earthquakes that occurred in Indonesia in 2023 with a minimum magnitude of 5.0 with various depths of 243 times. This condition is due to the geographical location of Indonesia is located between three tectonic plates so prone to earthquakes. Therefore, preventive measures are needed to reduce the impact of earthquakes on the failure of building structures. Faculty Of Engineering Building E.03 Tidar University is planned for 2015 with earthquake resistance Planning Standards in accordance with SNI 1726:2012. The planning standard has been revised to SNI 1726: 2019. Therefore, re-analysis according to the latest standards is required to determine the safety of the structure. Analysis using dynamic spectral response method. The maximum deviation of the roof ring beam in the x direction is 49.52 mm and the y direction is 61.25 mm. The largest shear force in the x direction is 7113.99 kN and the y direction is 6971.90 kN. The structural performance level is immediate occupancy with a roof drift ratio in the x direction of 0.0024 and y direction of 0.0030. Faculty of Engineering Building E.03 Tidar University has the ability to withstand earthquake forces with no damage to the structure. Keywords: dynamic response spectrum; seismic base shear force; structural performance level

Abstract

Pemanfaatan blockboard untuk plat lantai di Indonesia masih terbatas, padahal Magelang memiliki potensi produksi yang baik. Penelitian ini mengevaluasi pemanfaatan blockboard sebagai web dan kayu mahoni sebagai flens pada balok penyangga plat lantai kayu berbentuk I-Joist dan untuk mengetahui nilai Modulus of Rupture (MoR) dan Modulus of Elasticity (MoE) pada balok I-Joist .Metodologi menggunakan pengujian eksperimental berdasarkan ASTM D198-2015 dengan panjang balok I-Joist 200 cm, variasi tinggi 22, 24, 26, 28, dan 30 cm, dan setiap variasi terdiri dari dua benda uji. Fabrikasi dilakukan di SMK N 1 Magelang dan pengujian di Laboratorium Teknik Sipil Universitas Tidar.Hasil menunjukkan peningkatan tinggi tidak selalu berbanding lurus dengan kekuatan lentur. Nilai MoR: 22 cm (5,9333 MPa), 24 cm (7,2786 MPa), 26 cm (6,3287 MPa), 28 cm (6,0426 MPa), 30 cm (6,2524 MPa). Nilai MoE: 22 cm (1.545 MPa), 24 cm (1.098 MPa), 26 cm (1.140 MPa), 28 cm (1.335 MPa), 30 cm (940 MPa). Balok tinggi 24 cm menunjukkan MoR tertinggi (6,70 MPa).Secara keseluruhan, variasi tinggi 24 cm memberikan performa terbaik dengan kekuatan lentur optimal. Kombinasi blockboard-mahoni menunjukkan potensi sebagai alternatif material konstruksi ekonomis.
