Abstract

Kelemahan bambu untuk bahan bangunan adalah bambu rentan terhadap gangguan jasad renik, serangga, perubahan temperatur, dan air hujan. Sedangkan usaha pengawetan yang banyak dilakukan dinilai kurang effektif, karena memerlukan waktu yang lama, menimbulkan bau, dan merusak warna bambu atau garis-garis dekorasi bambu. Penelitian ini dilakukan guna menghasilkan bambu yang kuat, absorbsi kecil, tidak berbau, dan tetap memiliki garis-garis dekorasi, tetapi dengan proses waktu pengawetan yang cepat. Metode penelitian dilakukan dengan cara modifikasi metode Baucherie, yaitu dengan cara mengalirkan suspensi semen dengan bantuan kompresor ke dalam bambu segar atau bambu baru tebang, dimana pori bambu masih terbuka sempurna. Proses suspensi akan membuat pori-pori bambu terisi oleh semen dan akan mengeras. Variasi campuran suspensi semen : air ditetapkan sebesar 1:8, 1:7, 1:6, 1:5, dan 1:4. Pengujian dilakukan guna mengetahui campuran suspensi optimal dan perubahan karakteristik fisik dan mekanika bambu setelah tersuspensi semen. Hasil pengujian yang dilakukan terhadap 3(tiga) jenis bambu yaitu Ampel, Wulung, dan Tali menunjukan bahwa, kadar campuran suspensi semen optimal adalah sebesar 1:7 dan akan meningkatkan nilai kerapatan, kuat tekan, dan kuat lentur bambu masing-masing sebesar 47,76% ; 25,84% dan 36,02%, dan menurunkan nilai absorbsi dan elastisitas bambu masing-masing sebesar 20,13% dan 20,84% terhadap nilai karakteristik bahan bambu awal sebelum disuspensi.

Abstract

Productivity growth in the construction is lower than that of in the industry sector. Level of innovation in this sector is too low. Many problems of inefficiency in the construction process are a lotof waste of resources that do not produce value. According to  LCI (Lean ConstructionInstitute) waste in the construction industry is about 57% while the activity that adds value is only 10%. The construction industry has a lot to learn from manufacture industry. Some innovations by applying an appropriate and efficient  methods in the field of construction adopted many of the manufacturing, including modular systems/fabrication (precast concrete). Construction materials are mass produced in acontrolled environment and then assembled inthe site. The use of precast on any project shows that there are advantages obtained are: cheaper, faster/more productive and guaranteed quality. The duration of the Rusunawa (Simple Flats for Rent) Structure construction phase in Cilacap for precast method is 168 days while for the implementation of the conventional method is 196 days. The duration of the construction of precast structures is faster 28 days (14%) faster than that of the conventional structures. In high-speed rail project on the border of Belgium and the Netherlands, use Rheda 2000 NL method, which development of Rheda method, can increase productivity and lower overtime costs as 24.6%. In the residential case, quicklyconstructed building criteria can be categorizedinto several aspects, such as dimensions, weight components and connection systems.The suitable selection criteria will accelerate instalment proses of the wall panel.

Abstract

Reinforcement Foundation is a method to increase the capacity of supporters, so they can support the load of the building. This is required for buildings located on soft ground. Strengtheningthis foundation is also needed if the structure above will be increased so that the burden of building work increased. In this study, attempted to strengthen the foundations of the method by placing the sheet piles on the side of the foundation. Tests performed on two-dimensional model in thelaboratory, by comparing the carrying capacity of thefoundation with sheet piles and without sheet piles. Strengthening the foundation carried outwith3 (three) length variation of plaster that is: L / B = 0.75, L / B = 1.00 and L / B = 1.25. B, and 3 (three) variations in thelocation of plaster, which is in distance S /B = 0.5, S / B = 1.0 andS / B = 1.5. Test results showed that the installation of sheet piles can increase the capacity of foundation support. The results ofthis study showed the longer the higher the sheet piles supporting capacity building, with the results of 33%, 55% and (80% -100%), one each for L/ B = 0.75; 1.00 and 1.25. However, increasedcapacity is not much influenced by the location of plaster especially for short plasterof L / B = 0,75 and L /B = 1,00. While for L/ B =1,25, where the sheet piles getting closeto the foundation, increase capacity increased aswell..

Abstract

ABSTRAKPelat lantai merupakan bagian yang banyak dilalui berbagai alat berat dan kendaraan pada bangunan industri, gedung parkir, dan pergudangan. Oleh karena itu, dibutuhkan beton yang berkualitas baik untuk menghasilkan struktur bangunan kuat dan tahan lama. Proses pengecoran pelat lantai biasanya banyak terjadi penurunan agregat kasar sehingga permukaan pelat hanya tersisa agregat halus. Hal ini menyebabkan daya tahan aus dan kuat tekan beton menjadi rendah. Pengikisan terus menerus permukaan lantai pelat beton mengakibatkan penurunan dari mutu beton itu sendiri. Floor hardener merupakan bahan tambah yang bisa digunakan untuk meningkatkan ketahanan aus permukaan beton. Penelitian ini bertujuan untuk mengetahui pengaruh floor hardener terhadap ketahanan aus dan kuat tekan beton. Pengaruh penggunaan floor hardener juga akan meningkatkan biaya satuan untuk pekerjaan pelat beton tersebut sehingga faktor biaya juga ditinjau dalam penelitian ini. Dosis floor hardener yang digunakan pada beton yaitu  0, 3, 5, dan 7 kg/m2. Hasil pengujian menunjukkan bahwa kuat tekan mengalami peningkatan sebesar 3.18%, nilai abrasi beton turun 24.34%, dan semakin tinggi dosis floor hardener yang digunakan, semakin mahal pula biaya satuan pekerjaan pelat beton.Kata Kunci: Floor hardener, Kuat Tekan, Ketahanan Aus, BiayaABSTRACTThe floor plate is the part that is often passed by various heavy equipment and vehicles in industrial buildings, parking buildings, and warehousing. Therefore, good quality concrete is needed to produce a strong and durable building structure. The process of casting floor slabs usually occurs a lot of decrease in coarse aggregate so that the surface of the slab is left with only fine aggregate. This causes the wear resistance and compressive strength of concrete to be low. Continuous abrasion of the concrete slab floor surface results in a decrease in the quality of the concrete itself. Floor hardener is an additive that can be used to increase the wear resistance of concrete surfaces. This study aims to determine the effect of floor hardener on the wear resistance and compressive strength of concrete. The effect of using floor hardener will also increase the unit cost for the concrete slab work so that the cost factor is also reviewed in this study. The floor hardener doses used in concrete are 0, 3, 5, and 7 kg/m2. The test results show that the compressive strength increased by 3.18%, the concrete abrasion value decreased by 24.34%, and the higher the dose of floor hardener used, the more expensive the unit cost of the concrete slab work.Key words: Floor hardener, Compressive Strength, Wear Resistance, Unit Cost

Abstract

ABSTRAKBangunan gedung tinggi menjadi pilihan utama di kota-kota besar di dunia karena harga lahan yang sangat mahal dan adanya kebutuhan untuk fungsi perkantoran, tempat tinggal, hotel, dan berbagai fungsi lainnya. Selain memberikan manfaat yang besar, bangunan gedung tinggi juga ada konsekuensi berupa meningkatnya risiko kebakaran pada bangunan. Kebakaran pada bangunan gedung tinggi dapat menimbulkan korban jiwa dan material. Untuk mengatasinya dibutuhkan strategi keselamatan terhadap bahaya kebakaran yang terintegrasi dan efisien. Saat ini, pendekatan keselamatan dilakukan dengan merancang, menerapkan dan memelihara sistem proteksi kebakaran menggunakan cara-cara tradisional.  Building Information Modelling (BIM) merupakan proses pemodelan gedung yang awalnya berbasis model 3D dan telah dikembangkan sampai 7D yang menyediakan informasi dan alat yang membantu proses perencanaan dan perancangan lebih efisien dan efektif dalam proses konstruksi. BIM pada awal kemunculannya berfungsi  untuk membantu fungsi perancangan, pembangunan dan pengoperasian gedung. Walaupun belum banyak dilakukan, saat ini mulai dikembangkan  fungsi BIM untuk membantu meningkatkan keselamatan kebakaran. Penelitian ini bertujuan untuk memperluas peran BIM untuk keperluan fire safety pada bangunan gedung bertingkat tinggi dengan pendekatan potensi pemanfaatan pada tahap pra konstruksi, konstruksi dan paska konstruksi, serta mengidentifikasi peralatan dan pekerjaan yang berhubungan dengan fire safety yang mendukung peningkatan keselamatan kebakaran pada bangunan gedung tinggi. Metode yang dilakukan yaitu metode kualitatif deskriptif yaitu dengan kajian literatur dan validasi pakar dengan cara wawancara.  Hasil yang didapat berupa proyeksi ideal penggunaan BIM untuk meningkatkan keselamatan kebakaran pada bangunan gedung tinggi. Hasil proyeksinya divalidasi oleh ahli BIM dan fire safety.Kata Kunci: BIM, keselamatan kebakaran, bangunan gedung bertingkat tinggiABSTRACTHigh rise building has been the main choice in big cities across the world as land price is significantly expensive and the needs for office, residence, hotel and many others are increasing. While high rise building provides great benefits, it also has negative consequence with regard to increasing risks of fire in building. High rise building fire could cause fatalities and losses. To overcome it, an integrated and efficient fire safety strategy is required. To date, the approaches for safety are design, implementation and maintenance of fire protection system from the stage of pre-construction, construction and post-construction using traditional methods. Building Information Modelling (BIM) is a process of modelling a building that initially is based on 3D and it has been enhanced to 7D that provides information and tools to help planning and designing in construction process to be more efficient and effective.  At its initial emerge, BIM were used to help planning, construction and operational of buildings. Recently, BIM has also been employed to improve fire safety. This study aims to extend the application of BIM on fire safety in high rise building using the approach of utilizing its potency from the pre-construction, construction and post-construction stage, as well as identifying equipment's and works related to fire safety that support fire safety enhancement on high rise buildings. The method implemented was qualitative descriptive that performed using literature review and expert validation through in-depth interview. The result is an ideal projection of BIM implementation to heighten fire safety on high rise buildings. The projection was validated using BIM and fire safety experts.Key words: building information modelling (BIM), fire safety, high-rise building
