Abstract

Building construction planning in Indonesia uses SNI 2847: 2013 regulatory guidelines especially in building planning. So we need a combination of standardization used with technological developments that are realized in a computer program to simplify and speed up calculations. The results of the calculation of beam structures and concrete columns in the final project calculations using SNI 2847: 2013 regulations and analysis using SAP2000 code ACI318-14 software obtained the results: a) In plimelinary beam designs with sizes B1 30/40 cm and B2 40/55 cm are not able hold the load on the structure (over strange), then the beam dimensions are enlarged to B1 30/60 cm and B2 40 / 60cm. In the SAP2000 output analysis results after the beam dimensions are enlarged there are no over strange frames and meet the strength of the structure. b) From the beam analysis planning on bending reinforcement using SNI 03-2847-2013 concrete reinforcement regulations and using SAP2000 code ACI318-14 software analysis, the number of reinforcement obtained is more using SNI 03-2847-2013 concrete reinforcement regulations compared to using software analysis SAP2000 code ACI318-14 the amount of reinforcement used has a difference of 0.17%. c). From the planning of column analysis on bending reinforcement using SNI 03-2847-2013 concrete reinforcement regulations and using SAP2000 code ACI318-14 software analysis, the same amount of reinforcement is obtained between calculations using SNI 03-2847-2013 concrete reinforcement regulations and using SAP2000 code ACI318 software analysis -14.

Abstract

The concept of earthquake-resistant buildings is very meaningful to try on buildings located in certain earthquake areas, especially in Indonesia considering the situation which is located in a shock area with a fairly high intensity of events. The purpose of this research is to determine the seismic performance criteria of the planned structure using the SMRF (Special Moment Resisting Frame) structural system from the results of the displacement values using the ATC-40 code, showing the yielding scheme (plastic joint distribution) that occurs from the calculation results of the software program, knowing the pattern of building collapse so that it can be known joint- joint that is damaged and damaged from the pushover analysis. From the results of the research, the building structure is able to provide nonlinear behavior which is indicated by the initial phase and the majority of the occurrence of plastic joints occurs in new beam elements and then column elements and has fulfilled the earthquake-resistant building concept, namely strong column - weak beam. The results of the structural performance evaluation according to the ATC-40 rule that the Performance Level of the SMRF building in the x and y directions is at a Performance Level of 0.011 in the Immediate Occupancy (IO) category where the building is safe during an earthquake, the risk of loss of life and structural failure is not too significant, the building does not experience significant damage, and can be reused and not disturbed by repair problems, where the strength and stiffness are approximately the same as the conditions before the earthquake.

Abstract

In planning and controlling a project, it is often faced with various obstacles, for example, there is a shortage of materials, errors in the work order. In this project there was a delay due to a pandemic which caused the project to be hampered which initially could run according to schedule but became not according to the specified schedule. To minimize the impact of risks that occurred, a project scheduling method was developed using a probabilistic duration, one of which was PERT ( Program Evaluation and Review Technique). In this study, PERT (Program Evaluation and Review Technique) simulation was implemented which was implemented in the Grand Shamaya basement construction project based on the optimistic, pessimistic, and possible durations obtained from the survey results by the project management. PERT calculation using Microsoft Project 2013 software which produces an optimistic duration of 530 days, then for a possible duration of 535 days, a pessimistic duration of 551 days, and finally for a simulation result duration of 534.6 days. The difference in the schedule for the basement construction project of the Grand Shamaya Surabaya apartment when compared to scheduling using the PERT (Program Evaluation and Review Technique) method is the length of duration and the probability of project completion. So the duration of the plan schedule for 535 days produces a probability of 53.19%. The difference in the schedule for the basement construction project of the Grand Shamaya Surabaya apartment when compared to scheduling using the PERT (Program Evaluation and Review Technique) method is the length of duration and the probability of project completion. So the duration of the plan schedule for 535 days produces a probability of 53.19%.

Abstract

Kualitas kelulusan pendidikan tinggi yang masih belum memenuhi harapan dan standar kompetensi kerja, dampak globalisasi yang akan menciptakan persaingan ketat perlu disikapi dengan mempersiapkan kualitas kelulusan pendidikan tinggi yang mampu bersaing. Pertumbuhan pemenuhan tenaga kerja yang terlibat dibidang jasa konstruksi terus meningkat seiring dengan tumbuhnya sektor konstruksi di Indonesia, untuk memenuhi hal tersebut maka dibutuhkan lulusan pendidikan tinggi yang memiliki kompetensi ini. Dengan diterbitkan Peraturan Presiden Republik Nomor 8 Tahun 2012 tentang Kerangka Kualifikasi Nasional Indonesia (Perpres 8/2012 tentang KKNI) dan ditetapkan Peraturan Menteri Pendidikan dan Kebudayaan Republik Indonesia Nomor 49 Tahun 2014 Tentang Standar Nasional Pendidikan Tinggi (Permendikbud 49/2014 tentang SN Dikti), maka perlu ada pemahaman yang memadai dan arah yang benar untuk menerapkan kebijakan tersebut. Dengan rencana diterapkannya peraturan baru maka muncul pertanyaan mendasar yaitu, apakah model sistem manajemen yang berbeda-beda di masing-masing Perguruan Tinggi dapat mempengaruhi capaian pemenuhan (target dan waktu) standar mutu minimal, Hal ini memerlukan evaluasi internal oleh Perguruan Tinggi itu sendiri dan juga evaluasi eksternal oleh kementerian. Adanya persyaratan untuk tenaga ahli konstruksi harus memiliki pengalaman antara 2 sampai dengan 4 tahun dari tahun kelulusan, hal ini akan mengurangi kesempatan kerja bagi lulusan Perguruan Tinggi dan secara tidak langsung belum mengakui kualitas dari lulusan Perguruan Tinggi siap untuk bekerja di sektor konstruksi. Untuk menjembatani antara kesenjangan antara kompetensi lulusan suatu program pendidikan tinggi dengan kompetensi keahlian maka harus ada sistem akreditasi yang saling menunjang antara sistem akreditasi pendidikan dan sistem akreditasi profesi dan memasukan pendidikan profesi kedalam kurikulum pembelajaran. Variabel yang berpengaruh signifikan terhadap kualitas pendidikan tinggi adalah dosen, kurikulum, mahasiswa, proses pembelajaran, dan sarana/prasarana. Strategi untuk meningkatkan kualitas pendidikan tinggi adalah memperhatikan peraturan yang mengatur tentang pendidikan tinggi, dengan melihat potret kesenjangan antara kompetensi lulusan pendidikan tinggi dengan kompetensi tenaga ahli konstruksi, untuk meningkatkan kualitas dosen, kurikulum, mahasiswa, proses pembelajaran dan sarana/prasarana.

Abstract

Beton bertulang adalah suatu campuran yang terdiri dari pasir, batu pecah, atau agregat-agregat lain yang dicampur menjadi satu dengan suatu pasta yang terbuat dari semen dan air yang membentuk suatu masa mirip batuan. Sifat dari beton yaitu kuat terhadap tekan dan lemah terhadap tarik, oleh karena itu dibutuhkan tulangan baja untuk melengkapi kelemahan dari beton tersebut yang lemah terhadap tarik, yang mana sifat dari tulangan baja itu sendiri adalah kuat terhadap tarik. Beton bertulang mempunyai ketahanan yang tinggi terhadap api dan air, bahkan merupakan bahan struktur yang baik untuk struktur bangunan yang banyak bersentuhan dengan air. Pada peristiwa dengan intensitas rata-rata, batang-batang struktur dengan ketebalan penutup beton yang memadai sebagai pelindung tulangan. Material beton bertulang ini bisa dibuat dari bahan-bahan lokal yang murah, seperti pasir, kerikil, dan air, dan relatif hanya membutuhkan sedikit semen dan tulangan baja Tujuan dalam penelitian ini adalah merencanakan dan menganalisa dimensi kolom, balok dan pelat terhadap gedung bertingkat tujuh lantai. Serta, menganalisa dan membandingkan bermacam-macam mutu beton terhadap biaya yang ditimbulkan, Mutu beton tersebut yang diteliti antara lain K-300, K-350, K400, K-500. Dari keempat mutu beton yang diteliti manakah yang paling murah. Berdasarkan perhitungan yang telah dilakukan mutu beton dengan harga yang paling murah adalah mutu beton K-300.
