Abstract

Ancaman kebakaran gedung yang disebabkan oleh kegagalan instalasi listrik tetap berlangsung setiap saat, selama ada penggunaan energi listrik dalam gedung. Karena ada banyak penyebab kegagalan instalasi listrik seperti sambungan buruk, kualitas bahan yang tidak memenuhi standard dan instalatur yang tidak profesional. Kemudian metode konvensional seperti deteksi suhu, deteksi asap, dan deteksi nyala api tidak memberikan hasil yang baik, khususnya jika ada percikan bunga api yang tertutup di dalam bangunan gedung.                Kebakaran adalah salah satu bencana yang paling serius di gedung-gedung tinggi, maka pencegahannya terpaksa memasang peralatan yang mahal tetapi tidak mengharapkan penggunaannya. Sebab itu, penelitian ini menerapkan metode baru pendeteksi kegagalan instalasi listrik dengan pengamatan pada perubahan unjuk sifat sistem, sebagai indikator awal, mulai  terjadinya  proses kebakaran. Pemecahan dengan menerapkan pemodelan dan perumusan berbasis ilmu pengetahuan kecerdasan buatan dalam  membentuk rumusan unjuk sifat sistem yang normal secara tepat. Dengan rumusan tersebut sebagai referensi jika ada perubahan karakteristik yang membahayakan terjadi dalam sistem, sehingga aliran listrik kedalam gedung diputuskan sebelum ada perbaikan. Hasil uji coba di laboratorium menunjukkan tingkat keberhasilannya dapat mencapai 95 hingga 100 persen.

Abstract

Building Information Modelling (BIM) adalah sebuah pendekatan untuk desain bangunan, konstruksi, dan manajemen. Software Tekla merupakan revolusi baru dalam bidang rekayasa struktur yang memiliki beberapa keunggulan dibanding program aplikasi lainnya. Tekla Structures merupakan perangkat lunak Building Information Modelling (BIM) yang memungkinkan untuk membuat dan mengelola data secara akurat dan rinci, serta dapat membuat model struktur 3D tanpa melupakan material dan struktur yang kompleks. Penggunaan BIM di Indonesia masih hanya sebatas menjawab persoalan bagaimana mengefisiensikan kebutuhan tenaga kerja, waktu dan uang. Jika kita berkaca pada bagaimana pengaplikasian metode BIM di negara lain, potensi yang dicapai dari pengaplikasian metode BIM di Indonesia masih jauh dari kata maksimal. Tantangan selanjutnya adalah bagaimana mengenalkan teknologi aplikasi BIM ini dan mendorong penerapan BIM ini ke seluruh pihak stakeholder sektor konstruksi yang terkait. Maka dari itu, kegiatan pengabdian pada masyarakat ini bertujuan untuk memberikan pengenalan tentang Building Information Modelling dan memberikan keterampilan dasar dalam penggunaan aplikasi teknologi BIM dengan software Tekla Structures. Kegiatan ini dilaksanakan di Departemen Teknik Sipil, Universitas Hasanuddin yang dihadiri oleh 35 peserta yang berasal dari kalangan praktisi dan akademisi. Tahapan kegiatan pengabdian meliputi kegiatan sosialiasi ke stakeholder melalui mitra Lembaga Pengembangan Jasa Konstruksi Provinsi Sulawesi Selatan (LPJKP Sul-Sel), pengumpulan data berupa shop drawing, pembuatan modul, pemodelan dan laporan berupa quantity dan gambar kerja.

Abstract

One way to restore or increase the strength of the structure against earthquakes is to use retrofit method and wire mesh is a material that has high prospects as retrofit material. The purpose of this study was to examine the use of wire mesh as a retrofit material on reinforced concrete columns burdened with cyclic loads. In this study, testing of 3 square column samples of reinforced concrete with dimensions of 300  300 mm. The first specimen is fully retrofit on the entire cross-section of the column, the second specimen is retrofitted on the plastic hinge area of the column and the third specimen is a control column without retrofit. In the first and second specimens were retrofitted with wire mesh size M6 using SCC which was then tested with a cyclic load using displacement control method based on the provisions stipulated in the Indonesian Standard SNI 7834:2012. From the test results and analysis results, it was found that the capacity and ductility of displacement in retrofit specimens increased significantly compared to specimens that were not retrofit. In addition, the decrease in stiffness in retrofit specimens was smaller than in non-retrofit specimens. As for the value of energy dissipation in fully retrofit specimens and in retrofit on the plastic hinge area is almost close. Based on these conditions, the use of wire mesh size M6 and SCC can be used as retrofit material on the column that is burdened with cyclic load. Doi: 10.28991/cej-2021-03091685 Full Text: PDF

Abstract

This study is intended to determine the composition of the concrete mixture, the strength of the concrete and the ratio of the strength of the concrete with the combination of nickel slag and steel slag as a substitute for fine aggregate and coarse aggregate. The percentage of use of nickel slag waste of 50% as a substitute for fine aggregate and steel slag waste varies from 0%, 15%, and 30% as a substitute for coarse aggregate in high quality concrete mixtures (f'c = 42 MPa). In this study, the mix design uses the SNI 03-2834-200 method. The specimens used were 36 cylinders with a diameter of 15 centimeters and a height of 30 centimeters and 9 beams with a size of 15x15x60. Tests made in 7 days, 21 days, and 28 days age variations. Based on the mechanical properties of the average concrete using steel slag waste as a substitution at 30% variation, the greatest results were 45.27 MPa, 4.91 MPa and 5.09 MPa respectively for compressive strength, split tensile strength and concrete flexural strength.

This study aims to determine the development of concrete strength based on concrete compressive strength, split tensile strength, flexural strength, and modulus of elasticity in normal quality concrete mixtures based on variations in the Water Cement Factor (FAS), namely Variations 0,49, 0,52 and 0,55 where the variation with the highest compressive strength is used to further testing. The Mix Design method used is the American Concrete Institute (ACI) method with a design concrete quality of 25 MPa. From the results of the study, the highest strength value was found in the FAS variation of 0,49 with an average compressive strength of 7 days, 14 days, 21 days, and 28 days, respectively, with a compressive strength of 16,977 MPa, 23,301 MPa, 25,276 MPa, and 26,691 MPa. The results of the research carried out, the characteristics produced from the Mata Allo river meet the SNI specification standard to be used as a concrete mixture.
