Abstract

 Penelitian penggunaan slag semen pada campuran beton sebagai cementious telah dimulai sejak tahun 1774. Saat ini di negara-negara maju slag semen telah dimanfaatkan pada setiap campuran beton, bahkan persentasenya mencapai 30% dari cementious, hal ini dapat dilihat dari produksi slag semen yang terus meningkat dari tahun ke tahun. Pembuatan beton dengan menggunakan slag sement sebagai campuran agregat halus untuk subtitusi terhadap semen yang selanjutnya dilakukan pengujian terhadap benda uji beton untuk mengetahui seberapa besar pengaruhnya terhadap nilai kuat tekan pada beton, serta bertujuan juga untuk mendapatkan campuran bahan beton dengan biaya yang lebih efisien dibandingkan beton non-slag. Kuat tekan Beton akan mengidentifikasi mutu dari sebuah konstruksi, semakin tinggi kekuatan struktur yang direncanakan , maka semakin tinggi pula mutu beton yang harus di hasilkan. Beberapa faktor yang mempengaruhi kuat tekan beton, yaitu faktor air semen (w/c), jumlah air, jumlah dan kualitas semen, kualitas agregat, umur beton,  serta perawatan beton. Apabila w/c tidak sesuai dengan beton yang direncanakan maka beton akan mengalami perubahan kekuatan.  Hubungan antara kuat tekan beton dengan nilai w/c berbanding terbalik, kuat tekan akan menjadi tinggi apabila angka w/c kecil dan sebaliknya kuat tekan akan rendah apabila w/c makin besar. Hasil penelitian ini menunjukan bahwa perbandingan komposisi untuk memperoleh mutu yang sama didapatkan hasil pada beton slag ada penambahan air 7 liter/m³ terhadap non-slag, dan mengurangi sementious sebesar 2 kg/m³, serta slag semen memberikan kontribusi terhadap kuat tekan lebih besar dari pada beton non-slag  sebesar  4,3%, akan tetapi dalam mencapai hal itu, slag semen membutuhkan air yang lebih banyak, sedangkan dari segi biaya, dibandingkan beton non-slag, slag semen dapat menekan biaya sebesar  Rp 15.354,00/m3.

Abstract

Success in the construction industry is related to the efficiency and effectiveness of project implementation. Construction projects are not only very complex, but also require project management in daily work in terms of efficiency and effectiveness. This study uses a study-survey type, the purpose of which is to examine and explain project management possibilities for the successful implementation of a project at STS-Pamulang. The statistical calculation used is the crosstab which tests whether there is a relationship between the lines consisting of: planning , controlling , organizing and directing the time, cost and quality of the project. The results of the study make it possible to conclude that, according to the respondents, the project management function influences the success of project implementation at STS-Pamulang. According to respondents, planning and control variables are two aspects that have a significant influence on the success of project implementation at STS-Pamulang. To achieve this success, stakeholders wish to reduce project duration/time by expanding the planning and organizational aspects of project management. If you want to reduce your overall costs, you need to improve the planning and management aspects. And finally, if we want to improve the quality of our projects, we need to improve the planning and management of project management.

Abstract

In a project, it is necessary to have a work between owners and contractors that are used as a legal basis, in the form of construction contracts. One of these contracts is a contract for the procurement of goods and services based on the charge of its fiscal year consisting of a single-year contract which is the execution of a contract of work binding funds for 1 year while the contract of the plural year is a contract for the execution of work for a period of more than one fiscal year on the budget. Project delays almost occur every year and this results in huge losses for service users and service providers both in terms of finance and time. Project delays are divided into several types, namely: excusable delays, unforgivable delays, and delays that get compensation. Project delays are caused by several factors such as late payments and design changes. This factor greatly affects the performance of implementation in the field. The research process is carried out by conducting a survey. Starting with disseminating questionnaires to Owners, Contracts and outside parties as well as through literature studies, it is carried out to find out the comparison of the causes of project delays

Abstract

Abstract: The Green House display building is an exhibition building of living plants from various mountains in Indonesia including the mountains of Java, the mountains of Sumatra, the mountains of Kalimantan, and the mountains of Papua. This building is the only building in Indonesia, which presents the atmosphere of the mountains exactly the same as the original mountains, both plants, soil and air temperature, but is in a closed room. This building is very prone to fire because there are so many flammable materials such as leaves, wood and others. Therefore, the application of Building Fire Safety Management in this building must be applied as well as possible. To analyze the above, an inspection of the building's fire safety system equipment will be carried out for compliance with applicable regulations. The analysis will be carried out by checking directly and participating in tests or tests on the function of the installed fire protection system. The inspection and testing of the fire safety system in question includes: checking the completeness of the fire protection system, checking the use of fireproof materials, checking the provision of evacuation route access and checking the reliability of fire safety. Based on the results of the inspection and tests, it can be concluded that based on NFPA standards and the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia No: 4/MEN/1980, yard hydrant equipment and Light Fire Extinguishers in the Green House Display building, still do not meet the requirements, but for the use of building materials in this building, almost all of them can be categorized as building materials that are quite resistant to fire/not flammable. For access to fire safety facilities/evacuation routes in this building is well installed and the radius of coverage is in accordance with the Indonesian Minister of Health Regulation number 48 of 2016, which is a maximum of 45 meters between emergency stairs. As for the reliability of the building safety system in this building, it can be categorized as "Good" based on the Puslitbang PU Pd-T-11-2005-C.

Abstract

Dengan berkembangnya teknologi didalam dunia konstruksi khususnya di negara Indonesia semakin banyaknya inovasi yang digunakan dalam proses konstruksi. Salah satu nya yaitu dalam penggunaan cetakan beton (bekisting). Bekisting harus memenuhi syarat kekuatan, kekakuan, dan stabilitas. Syarat ini harus dipenuhi karena penggunaan bekisting digunakan secara berulang-ulang pada gedung bertingkat dan memerlukan biaya yang besar untuk menggunakannya. Posisi pemasangan bekisting harus berdiri tegak, kokoh dan kuat agar mampu menahan beban-beban yang terjadi seperti beban vertikal dan beban horizontal. Pemasangan bekisting kolom dapat dikerjakan setelah pemasangan tulangan kolom telah siap. Kolom adalah salah satu elemen struktur vertikal yang berfungsi meneruskan beban aksial lalu diteruskan ke pondasi. Pengerjaan tulangan kolom harus memerhatikan dimensi tulangan, jumlah tulangan utama dan tulangan sengkang, serta jarak antar tulangan utama dan tulangan sengkang. Tujuan dari penelitian ini adalah untuk mengetahui perbandingan pemasangan tulangan kolom kotak dan kolom bulat, mengetahui perbandingan penggunaan bekisting jenis konvensional dan bekisting jenis pelat baja serta mengetahui beban yang dipikul oleh kedua bekisting tersebut saat pengecoran. Metode yang digunakan dalam penelitian ini adalah deskriptif studi kasus. Pengumpulan data primer dilakukan dengan pengamatan secara langsung, wawancara kepada staff lalu menganalisis data. Sedangkan pengumpulan data sekunder diambil dari buku literatur, jurnal, dan internet. Hasil penelitian menunjukkan bahwa beban hidup merata yang didukung oleh tulangan kolom dimensi 80x80 lebih besar dibandingkan dengan tulangan kolom dimensi 60x60. Mu = 6.273.10-5 t.m 3.287.10-5 t.m. Sedangkan penggunaan bekisting jenis pelat baja lebih baik dari segi penggunaan, waktu dan biaya dibandingkan dengan penggunaan bekisting jenis konvensional serta untuk beban mati dan kombinasi beban yang dipikul oleh bekisting jenis pelat baja lebih besar dibandingkan dengan bekisting jenis konvensional sehingga bekisting jenis pelat baja lebih kuat memikul beban yang terjadi saat pengecoran.

Abstract

There are two access bridges that have different functions, i.e., to cross the Ciliwung river as an access road from the RSCM Kencana building to RSCM Kirana, where there is access to the bridge that is specifically for car/motorcycle riders and a special bridge for pedestrians. However, the density of motorists and pedestrians can hinder traffic access. Thus, supporting infrastructure was built, namely a vehicle bridge and connecting pedestrians from the Kencana RSCM building to the Kirana RSCM building. The type of built bridge is a concrete slab steel frame bridge. This study aims to determine the values of the ultimate moment, shear, and axial forces that occur with the object viewed from the longitudinal and transverse girders whether they exceed the nominal profile value or not, and the deflections that occur on the behavior of the structure on the bridge based on SNI 1725:2016 loading with the aisstance of the MIDAS Civil 2019 software. The results of the calculation and capital analysis on the MIDAS Civil 2019 software, the values of the internal forces on the object under review do not exceed the nominal strength value of the profile. First, the girder extends against ultimate moment of ϕMn ≥ Mu = 3.762,080 kNm ≥ 528,869 kNm, against shear force ϕVn ≥ Vu = 1.095,444 kN ≥ 909,282 kN, against axial compressive force ϕPn ≥ Pu = 8.532,876 k N ≥ 3.115,265 kN, to the axial tensile force ϕPn ≥ Pu 7.726,842 kN ≥ 2.434,744 kN. Second, the transverse girder with respect to the ultimate moment of ϕMn ≥ Mu = 1.242,046 kNm ≥ 53,723 kNm, against the shear force ϕVn ≥ Vu=1.076,400 kN ≥ 81,513 kN, against the axial compressive force ϕPn ≥ Pu = 3.805,349 kN ≥ 255,812 kN .The deflection value that occurs at the ultimate state of the structural behavior of the bridge is 48.70 mm, this value is smaller than the allowable deflection of 55 mm, making the bridge structure is safe when it receives the ultimate load.

Abstract

With the rapid development in the field of construction, various material innovations are increasingly emerging, especially in concrete. Concrete is in high demand for its durability, resistance to pressure, and low maintenance costs. Made from a growing mix of cement, coarse aggregate (split), fine aggregate (sand), water, and additives, concrete is becoming a top choice in modern infrastructure. This study aims to explore the relationship between compressive strength and flexural strength in 30 MPa quality concrete. The method used was a laboratory experiment with cylindrical and block-shaped test pieces, which were tested at the ages of 7, 14, and 28 days. The main materials used include coarse and fine aggregates, water, fly ash, and Portland type I cement. The study measured the compressive strength values of concreate, and evaluated the formula  \(fs=0.62√(fc^' ) \) as stated in SNI 2847:2013 to test its relevance to this quality concrete. The results showed that the flexural strength increased with the age of the concrete, with the largest difference between compressive strength and flexural strength at 1.3%. These findings support a deeper understanding of the performance of concrete at a given age and the relevance of the standard formula for 30 MPa quality concrete.
