Abstract

Indonesia is one of the countries that is prone to earthquakes. In addition to the dead loads, superimposed dead loads, and live loads, the design of buildings in Indonesia must be concerned with earthquake loads. Installing shear walls in the building structure as the Special Moment Frame Dual System is one of a solution to withstand earthquake loads. However, the location of shear walls must be considered, especially in buildings with horizontal irregularities. This study aims to determine the optimum location of the shear walls in a 10-storey building that has U-configuration with dynamic earthquake loads. This research is a numerical simulation ran by modelling the structure with software. To know the effect of the shear wall’s location on a building, several variations of the shear wall configuration with different positions have been conducted. It can be seen the lateral displacement of each floor and the shear force are the response structure to withstand the dynamic earthquake loads. Shear walls that are located close to the center of mass of the building are the optimum variation because the position of the shear wall is the closest to the core area of the building, which is the rotational axis of the building.

Abstract

Di Indonesia umumnya evaluasi geometri jalan dilakukan dengan cara konvensional seperti menggunakan theodolite atau total station. Kegiatan evaluasi merupakan bagian dari monitoring untuk memantau setiap perubahan kondisi jalan baik profil, kepadatan kendaraan dan lalu lintas. Penelitian ini bertujuan untuk melakukan evaluasi kondisi eksisting geometri jalan menggunakan UAV serta menganalisis ketelitian fotogrametri. Lokasi yang diambil dalam penelitian ini bertempat di Jalan Lingkar Dramaga. Kegiatan dilakukan dengan pengambilan foto udara menggunakan UAV bereferensi Titik Kontrol Bantu BIG pada beberapa Ground Control Point (GCP). Evaluasi dilakukan terhadap alinyemen horizontal dan alinyemen vertikal jalan. Evaluasi ini dilakukan setelah dilakukan proses orthophoto terhadap hasil foto udara. Alinyemen horizontal yang dievaluasi berupa sudut belokan, radius belokan, panjang belokan, dan sisipan antar dua tikungan. Evaluasi alinyemen vertikal berupa panjang lengkung dan kelandaian jalan. Hasil uji akurasi berdasarkan kondisi eksisting jalan sebesar 99.2% untuk orthophoto tanpa koreksi dan 99.6% untuk orthophoto terkoreksi ground control point. Berdasarkan hasil evaluasi terhadap kondisi eksisting jalan, alinyemen horizontal jalan telah memenuhi SNI T-14-2004 sedangkan pada alinyemen vertikal terdapat nilai kelandaian yang melebihi pada segmen A1-A2 sehingga dilakukan rekomendasi perbaikan berupa penambahan elevasi sebesar 0.50 m pada STA 0+390 berupa penambahan lapisan perkerasan.

Abstract

A project tends to experience delays if planning and control are not carried out properly. Various things can happen in a construction project that can cause an increase in processing time so that project completion is delayed. The purpose of this research is to identify and classify the factors that cause delays in the "XYZ" project. This data processing uses the help of the SPSS (Statistical Product and Service Solution) computer program version 23.00. Data analysis techniques using validity, reliability and factor analysis techniques. The results of this study obtained 3 new factors from the extraction results of factor analysis, namely: Lack of Expertise and Slow Material Mobilization (Xb1), Lack of Planning and Inadequate Quality of Workforce (Xb2), Changes in Scope and Work Documents (Xb3).

Abstract

One of the regions with high earthquake vulnerability is Java Island. The Sabilulungan 99 Tower, located in Bandung Regency, is a tower with a reinforced concrete structure that features a moment-resisting frame system. The structure's period is 2.6 seconds. The mass participation ratio obtained reaches values above 90% in both the x and y directions in the 9th vibration mode. The base shear force obtained when the performance point is reached in the post-elastic analysis is 10,402.90 kN in the x direction and 10,178.88 kN in the y direction. The lateral displacement of the roof in the x and y directions is 568.53 mm and 602.51 mm, respectively, when the structure's performance point is reached. Based on the structural deformation parameters according to FEMA 356 guidelines, the structure's performance level is Life Safety (LS). The structure's ductility in the x and y directions is 1.7 and 2.4, respectively, classifying the structure as having low ductility in the x direction and moderate ductility in the y direction.

Abstract

Berdasarkan BPJS Ketenagakerjaan, Data angka kecelakaan kerja di Indonesia menunjukkan peningkatan. Kecelakaan kerja yang terjadi pada tahun 2020 adalah sebanyak 221.740 kasus, dan di tahun 2021 menjadi sebanyak 234.270 kasus, naik 5,65% dari tahun sebelumnya. Penerapan safety induction dan mekanisme penggunaan APD merupakan prioritas bagi keselamatan  pekerja. Akan tetapi, pada pelaksanaan di lapangan, masih saja terdapat pekerja yang tidak  mengikuti aturan yang sudah ditetapkan perusahaan. Tujuan penelitian ini yaitu untuk menganalisis pengaruh variabel Jenjang Pendidikan, Tingkat Jabatan dan Pengalaman bekerja pada penerapan Keselamatan dan Kesehatan Kerja (K3) di pembangunan proyek konstruksi Gedung Resto Apung Muara Angke Jakarta Utara. Penelitian ini menggunakan Metodelogi Kuantitatif dengan teknik pengumpulan data melalui riset lapangan, kuisioner, pengutipan langsung dan riset kepustakaan. Teknik statistika yang digunakan saat analisa data adalah uji validasi, uji reabilitas dan uji hipotesis. Berdasarkan hasil pengujian hipotesis  penelitian, dapat disimpulkan bahwa variabel pendidikan, jabatan dan pengalaman bekerja berpengaruh terhadap variabel K3, dengan nilai relatif level Jenjang Pendidikan Sebesar 25,08%, Tingkat Level Jabatan sebesar 30,93%, dan Pengalaman Bekerja sebesar 43,99%. Penerapan K3 pada pembangunan proyek konstruksi Gedung Resto Apung Muara Angke sudah dilakukan dengan baik ditunjukan dengan adanya program  sosialisasi K3, penerapan rambu keselamatan dan spanduk K3, penerapan APD, prosedur Job Safety Analysis (JSA), dan Identifikasi Bahaya, Penilaian dan Pengendalian Risiko (IBPR) yang  dilaporkan ke manajemen, sehingga untuk selanjutnya penerapan K3 perlu dipertahankan dengan terus melakukan monitoring dan evaluasi berkala.

Abstract

The high potential earthquake in Indonesia made the earthquake an important factor in the planning of a building. The study aims to do the way of modeling, analyzing the inner style, displacement occurring in the current earthquake structure and knowing the vibration period and the stiffness of the structure. Research conducted in Kelapa Gading North Jakarta. Research using secondary data obtained from KSO Jaya Konstruksi-Adhikarya by using CSI Bridge. The flyover modeling is based on secondary data. The results show that 12 vibration modes may occur in the flyover structure. The largest period occurred in mode 1 that was equal to 0.84 sec which represented the behavior of the structure so that the total stiffness value of the structure was 275512.95 kN/m. Structures can be categorized as a flexible structure. Displacement is the structure of 92.5 mm and is still below the value of allowable displacement so it could be classified as the safe category. The force that occurs in the structure of the axial force, shear force, torsion, and flexure moment. Keywords: CSI Bridge, displacement, earthquake, flyover, force.
