Abstract

Keterbatasan bahan bangunan konvensional seperti kayu, baja, dan beton yang sering berdampak negatif terhadap lingkungan mendorong pencarian material alternatif yang lebih ramah dan berkelanjutan. Bambu menjadi salah satu pilihan karena memiliki karakteristik ringan, kuat, lentur, dan dapat diperbarui dengan cepat. Pada konstruksi umumnya, bambu utuh digunakan sebagai elemen utama atap, sedangkan lidi bundle hanya dipakai sebagai komponen tambahan. Akan tetapi, dalam penerapan terkini, lidi bundle mulai digunakan sebagai elemen utama meskipun belum ada kajian ilmiah yang mendukung kekuatannya. Penelitian ini dilakukan untuk menganalisis perbedaan kinerja antara bambu utuh dan lidi bundle melalui simulasi numerik dengan metode elemen hingga menggunakan perangkat lunak ABAQUS. Benda uji sepanjang 760 mm dimodelkan dengan tumpuan sederhana dan beban yang menyerupai kondisi riil. Pemodelan memakai elemen solid 3D tipe C3D8R dengan properti material yang diperoleh dari hasil pengujian laboratorium. Analisis mencakup kajian statik nonlinier untuk menilai deformasi serta distribusi tegangan, dan analisis buckling untuk mengevaluasi kestabilan. Hasil simulasi menunjukkan bahwa lidi bundle mampu menahan gaya maksimum sebesar 0,95 kN dengan deformasi lebih kecil, sedangkan bambu utuh hanya mencapai 0,023 kN. Temuan ini menegaskan bahwa lidi bundle memiliki performa lebih unggul dan berpotensi diaplikasikan sebagai elemen utama struktur atap bambu yang efisien, inovatif, dan ramah lingkungan.

Abstract

Kegiatan pengabdian masyarakat ini dilaksanakan di Pura Bangkak, Desa Sibetan, Kabupaten Karangasem, Bali, sebagai upaya mengatasi permasalahan ketidakstabilan dinding tanah pada area parkir pura yang memiliki ketinggian ±3 meter dan panjang ±50 meter tanpa struktur penahan. Kondisi tersebut menimbulkan risiko longsor yang dapat mengancam keselamatan dan keberlanjutan fungsi pura sebagai pusat kegiatan keagamaan masyarakat. Metode pelaksanaan meliputi survei lapangan, pengukuran geometri, pengujian tanah (SPT, kadar air, dan permeabilitas), serta pemetaan topografi menggunakan drone untuk memperoleh data kontur secara akurat. Berdasarkan hasil analisis, disusun desain teknis dinding penahan tanah berbahan beton bertulang dengan sistem drainase yang sesuai dengan karakteristik geoteknik setempat. Kegiatan ini juga mencakup sosialisasi dan pelatihan kepada masyarakat mengenai pemeliharaan serta deteksi dini kerusakan dinding penahan tanah. Hasil kegiatan menunjukkan peningkatan pengetahuan masyarakat dalam menjaga infrastruktur sederhana, terciptanya desain teknis yang aplikatif, serta penguatan sinergi antara akademisi, masyarakat, dan pemerintah desa. Program ini sejalan dengan implementasi Merdeka Belajar Kampus Merdeka (MBKM) serta mendukung pencapaian Indikator Kinerja Utama (IKU) perguruan tinggi melalui keterlibatan aktif dosen dan mahasiswa.

Abstract

Bridges are structures that need to be well-planned to function optimally. Bridges come in various shapes and sizes, one of them is an arch bridge. Through this thesis preparation the author tried to plan the upper structure of a bridge with an arch type on Tukad Ayung Bridge. The initial planning data includes a length of the existing bridge of 64 m and a width of 15 m. The planning method using LRFD and SAP2000 for the software. The arch rib dimensions in the planning of the through arch steel bridge on Tukad Ayung is 900.600.30.40 box profile with a cross-sectional height. It is using steel material of special type of structural steel for bridges with ASTM A 709 grade 50 specifications. From the analysis result, the stress melting point is fy= 345 MPa and the modulus of elasticity steel is E= 200000 MPa. The cross-sectional height is 900 mm, cross-sectional width is 600 mm, the body thickness (tw) is 30 mm and the wing thickness (tf) is 40 mm.

Abstract

Bali is one of the provinces that are destinations for foreign and domestic tourists. This causes Bali to follow developments in several sectors, one of which is the construction sector. Of course, every building in Bali must guarantee its safety and comfort. Especially in infrastructure buildings, the security of which must be guaranteed because it involves the safety of many people inside. For example, hospital buildings included in risk category IV need to pay attention to their deviations. For example, in the Udayana University oral dental hospital building which was previously planned using SRPMK, the design deviation value met the requirements or did not exceed the permit deviation. This oral dental hospital building will be re-planned using a dual system. So these two structural systems are chosen for comparison regarding the deviation values ​​between the two to provide information regarding which structural system is more optimal. In this writing, the analysis shows that the deviation value produced by the dual system is smaller than the special moment resisting frame system. Namely, with a maximum value of the double system of 8.96 mm and SRPMK with a maximum value of 21.696 mm with a clearance of 30.77 mm on the 2nd floor in the x direction and in the Y direction the maximum value of the double system is 12.60mm and SRPMK with the The maximum value is 20.07 mm with a permit of 26.92 mm on the 3rd floor.

Abstract

When planning a tall building structure, the deviation due to lateral forces is very important to be taken into account in the planning of tall building structures. To reduce the amount of deviation in the structure adding by special structural elements, as shear walls. With the shear wall, can increase the stiffness of the building structure and absorb large shear forces along with higher the building structure and lateral force on structure will not fully accepted by frame structure which will result a decrease in deviation. Guestwing 1 The Ritz Carlton Hottel located in South Kuta District, Badung Regency, Bali. This building has a height of 20.2 m consisting of 6 floors. Planning with 2 models: a) SRPMK Existing Modeling, b) Dual System Model. Material specifications and loading are the same, just different in addition of shear walls and reducing the dimensions the building. Based on the results the analysis of the two models, the largest inter-storey deviation value in the existing model X=52.014mm; Y=47.960mm and for the dual system model X=25.614mm; Y=26.026mm. From the results of deviation analysis on both models, can be concluded that with addition of shear walls, there is a decrease in deviation 63.27% in X direction and 68.18% in Y direction. The most significant decrease occurs in dimensions and reinforcement of column K1 from size 350x800mm with 22 D22 reinforcement to column 300x600mm with 18 D22 reinforcement, beam B3 250x450mm for support area 17 D13 and field area 10 D13 to beam 250x400mm with the number of support reinforcement 11 D13, and the number of field reinforcement 7 D13. From the results of this planning can be used as a consideration for the construction of the next building for the use of shear walls in the structure.
