Precast system is one of the reinforced concrete construction methods that can be used for development. GFRP-S (Glass Fiber Reinforced Polymer Sheet) is one of material that can be used as materials in precast concrete connections. The research aimed at analysing the strenght and behaviour of the concrete beams on beam-column joint precast with GFRP-S.The research was conducted at the Laboratory of Civil Engineering Structures and Materials Hasanuddin University. Beams dimensions was 15cm x 20cm x 120cm and the column was 45cm x 20cm x 100cm. The testing materials were the precast beams with GFRP-S. The imposition given is monotonic static load in one direction.The results showed that an increase in stiffness of the precast beams with GFRP-S. LSI amounted to 16.64% of the LS. LIS amounted to 31.70% of the LS. The average deflection of LS are 55.05 mm. The average deflection of LSI are 45.89 mm. The average deflection of LIS are 37.60 mm. The models of failure in the precast beams with GFRP-S are rupture failure of GFRP-S.
Artikel ilmiah merupakan sesuatu yang sangat penting dalam dunia kampus khususnya untuk mahasiswa dan dosen dimana bagi mahasiswa artikel ilimiah adalah syarat wajib untuk kelulusan sedangkan bagi dosen merupakan salah satu kewajiban tridarma perguruan tinggi serta sebagai syarat kenaikan pangkat dosen. Penggunaan aplikasi Mendeley Bagi mahasiswa merupakan salah satu kebutuhan untuk menulis skripsi dan menjadikan sebagai salah satu penyimpanan referensi skripsi sedangkan bagi Dosen pelatihan Mendeley mendorong percepatan publikasi ilmiah pada jurnal internasional bereputasi. Pelakasanaan Pengabdian Kepada Masyarakat (PkM) Pelatihan Penggunaan Mendeley dilaksanakan pada Program Studi Diluar Kampus Utama (PSDKU) UNTAD Morowali dengan pesertanya adalah mahasiswa sebanyak 45 orang, dan Dosen sebanyak 5 orang. Metode pelaksanaan yang digunakan pada Pelaksanaan PkM menggunakan dua Metode yakni knowledge transfer dan Model Community development dengan tahapan pelaksanaa; 1) perencaanaa, 2) Pelaksanaa, dan 3) evaluasi .pemaparan materi dilakukan melalui tatap muka di Program Studi Diluar Kampus Utama (PSDKU) UNTAD Morowali. Hasil dari kegiatan ini adalah 40 mahasiswa dan 5 dosen peserta sudah mampu untuk melakukan download, instalasi aplikasi plug in pada Ms. Word, mensitasi artikel, mencari referensi jurnal dan membuat daftar pustaka secara otomatis Citation Management Training (Using Mendeley) for Lecturers and Students of PSDKU UNTAD Morowali Scientific articles are something that is very important in the campus world, especially for students and lecturers, where students scientific articles are a mandatory requirement for graduation, while for lecturers it is one of the three obligations of higher education as well as a requirement for a promotion. from the lecturer. The use of the Mendeley application is a necessity for students to write theses and use it as a repository of thesis references, while for lecturers the use of Mendeley is needed to accelerate scientific publications in reputable international journals. The Community Service Training (PKM) with Mendeley was held Program Studi Diluar Kampus Utama (PSDKU) UNTAD Morowali with 45 students and 5 lecturers as participants. The implementation method used in the implementation of PkM uses two methods, namely the transfer of knowledge and the Community development model with the stages of implementation; 1) planning, 2) implementation, and 3) evaluation. The material was delivered face-to-face at the Main Campus Off-campus Study Program (PSDKU) UNTAD Morowali. The results of this activity were that 40 students and 5 participating lecturers were able to download, and install plug-in applications on Ms. Word, cite articles, look for journal references, and create bibliographies automatic.
Huntap (Permanent dwelling) is a building intended for people whose houses are affected by disasters. The main requirement is that the building be proven to survive if an earthquake occurs around the Permanent dwelling located in the future. This research begins with the completion of the architectural drawing of the Banua Tadulako’s House (Rumbako) according to input from the Spatial Planning and Settlement Service of Palu City and the Directorate of Housing and Settlement Engineering Development of the Ministry of PUPR. The next process is the preparation of materials and equipment. Structural analysis using SAP 2000 software. Based on the analysis and simulation results, the following results are obtained: The stresses that occur on the surface of the wall do not exceed the allowable stress of the brick wall infill material, The cross-sectional capacity of the reinforcing steel is quite safe against the combination of loading applied to the structure. The basic seismic shear force of the structure capacity from the pushover analysis is 226 kN. More than the design earthquake force of 121 kN. Minimum connection details and truss structural elements have been calculated and qualify the requirements for strength and stress ratio.
Colo Volcano is an active volcano located on Una-Una Island, Tojo Una-Una Regency, Central Sulawesi Province. Volcanism and magmatism of Mount Colo are still in progress, and this has certainly triggered mineralization in volcanic rocks which is interesting for study. This research aims to reveal the mineralization characteristics of volcanic rocks in the study area. This research was conducted through investigative methods in the form of field observations and laboratory through petrographic and rock chemistry (X-Ray Defraction analysis) to reveal the presence of alteration minerals as a characteristic of mineralization. The results of this study indicate that the volcanic rocks present are tuff and volcanic breccia in the form of pyroclastic deposits associated with alluvial material and andesite rocks. Identification of alteration minerals through XRD test shows the presence of hydrothermal alteration minerals with a formed temperature of 300 ° C such as Quartz, Calcite, Clinochlore, Albite, Dickite, Andesine, and K-Feldspar which are classified into Argillic and Propylitic alteration types.
Nupabomba village roads frequently undergo landslides, so that detain transportation access flow pattern as a result of rock slope stability problem, which has become the landslides trigger. Furthermore, to find out landslides prone area slope stability level, an analytical study using a scientific approach is required to reveal this question in the study area. The slope elevation in this area is ± 75 meters, with an average slope angle of 60°, where its lithology consists of Schist, Greenschist, Filite, and Granite. Some of these rocks have different weathering levels (e.g., slightly - high weathering), and there are lots of discontinuity. Moreover, its geological strength index (GSI) value showed around 15-75 with the surface shape of blocky and disturbed. Besides, the uniaxial compressive strength (UCS) value was obtained based on the compressive strength carried out in the field, and slope stability rating (SSR) values have gained the range of 9-81.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
