Abstract

Foundation is a structure that functions to withstand loads above it and the load itself. These loads are transferred to the ground directly. The case study in this plan is the construction of the Dwi Indah Building in Selodono Village, Kediri Regency. The building has a building area of 308 m2 and a height of 16 m, with the function of the building as an inn. In this planning, the type of pile foundation is used. A Pile foundation is a type of deep foundation that divides the gravity load evenly on the ground and makes the structure of the building strong and strong. The purpose of this planning is to plan a strong pile foundation that is able to withstand the load of the Dwi Indah Building. The method used in this planning is the Meyerhoff method, with a pile diameter of 30 cm and a foundation depth of 800 cm. From the calculation results obtained (single pile bearing capacity) Pall= 42.62 tonnes greater than (maximum pile load) Pmax= 26.00 tonnes (SAFE). For the control of the yield of the buckling factor, the result is (buckling) ω= 178.61 kg/cm2 <(base stress) σ = 2400 kg/cm2 (SAFE).

Abstract

There are several factors that need to be considered in road development planning, such as soil structure, traffic conditions, rainfall, and drainage networks. These things need to be considered because they affect the quality of the road. The road guyangan – simpang empat candi is the main road with a flexible pavement structure. The structure is deemed not suitable for a load of passing vehicles. In terms of these conditions, it is necessary to change the pavement structure to the rigid pavement. The rigid pavement itself is an arrangement of road pavement structures which on the top layer uses cement concrete plates. This study aims to plan the thickness of the rigid pavement, the characteristics of the concrete, and the required budget. The method used to plan is by using the 2017 revised road pavement design manual method. The calculation results obtained concrete with quality class III with 28 days of compressive strength of 350 kg / cm2, the thickness of concrete slab 305 mm with details of the cost of Rp. 12,746,095,600.00 (Twelve billion seven hundred forty-six million ninety-five thousand six hundred rupiahs).

Abstract

Accelerated development of cross-coastal access to southern eastern Java, known as the South Coast Cross Lane (JLS) very dependent with the topography of the southern region of Java island, about 65% of JLS are in mountainous and coastal areas. One of them is the construction of Dimoro Bridge in Malang East Java region with simple composite girder type spans 20.00 meters. According to basic design, girder dimensions use IWF. 980 x 350 x 10 x 35, with the number of girder n = 7 and the girder length 20.40 m. The issue of girder dimensions IWF. 980 x 350 x 10 x 35 is not mass-produced by the steel industry, so there needs to be a design review with the dimensions of girder in the steel industry market with IWF. 800 x 300 x 14 x 26. The analysis of dimensional changes and the number of simple composite girder is reviewed from : (1) the height of the girder profile approaching plan (d), because when the smallest (d) value is taken there will be more number of girder (n) installed. (2) the weight of the bridge structural steel approaching plan (Wr), since if Wr' < Wr means fulfilled by not changing the calculation of the bridge foundation, if Wr' > Wr then it is necessary to recalculate the strength of the bridge foundation. Analyze results for bending moments on IWF girder. 800 x 300 x 14 x 26 is obtained : M precomposite = 43850 kg.cm, M post-composite = 13816200 kg.cm. The moment of resistance (wb) due to Mpre and Mpost = 5003 cm3. Moment of inertia (Ix) = 282554 cm4 (table Ix = 292000 cm4). The moment of resistance (wx) = 7064 cm3 (table wx = 7290 cm3). Control of ultimate stress σau* = 2780 kg/cm2 is obtained Mmax = 12030000 kg.cm, σa' = Mmax/wx = 2405 kg/cm2 > σa = 1850 kg/cm2, the stress σa' exceeds the permit stress σa but still below ultimate stress σau* (safe). Control of deflection, for L/250 obtained Ix = 157733 cm4 < Ix plan = 282554 cm4 (safe). For L/360 obtained Ix = 201819 cm4 < Ix plan = 282554 cm4 (safe). Control of the shear stress obtained T = 229.76 kg.cm2 <T'= 0.58xσa = 0.58 x 1850 = 1073 kg.cm2 (safe). Control of tensile stress and press on composite girder, compressive stress σsu = 389.7 kg/cm2 < σa = 1850 kg/cm2 (safe), tensile stress σsl = 1123.3 kg/cm2 < σa = 1850 kg/cm2 (safe). Preferred on the composite girder is the compressive stress (σsu), and the resulting compressive stress (σsu) after the composite is smaller than the allowable stress (σa = 1850 kg/cm2; σau* = 2780 kg/cm2), the dimensional change IWF girder being 800 x 300 x 14 x 26 is safe to use. The change of girder number to IWF 800 x 300 x 14 x 26, profile area F = 261 cm2 (table F = 267 cm2), girder weight per m wt1 = 261x0.785 = 205.00 kg/m' (table = 210.00 kg/m'), weight 1 girder Wt(p) = 4100 kg. Needs of girder n'= Wt7/Wt(p) = 9.40 → taken 9 girder, Wt9 = 36900 kg < Wt plan = 38556 kg (ok). Accessories on the composite girder include : connection plate + bolt, diaphragm (bracing iron elbow) + bolt, shear-connector. Total weight of Accessories 9 girder = (3692+215+737) = 4644 kg. Total weight of composite bridge steel structure 9 girder Wr = 36900+4644 = 41544 kg < weight plan Wr = 41635 kg (fulfilled by not changing bridge foundation calculation). Keywords: pre-composite moment, post-composite moment, ultimate stress, deflection, shear stress.

Abstract

Concrete is a building construction material that has an important role. Concrete itself tends to have strong properties in resisting compressive forces, but weak in resisting tensile or flexural forces. The use of additives in concrete is an option to improve the basic properties of concrete. Latex or rubber latex is one of the natural materials that can be used in concrete mixtures. Its adhesive properties can be utilized in improving the quality of concrete. This study aims to determine the compressive strength and flexural strength of concrete with the addition of latex. The research was conducted experimentally by making concrete specimens in the laboratory. The addition of latex by 10% and 30% with a planned concrete quality of fc' 29.5 MPa. The test object used is a cylinder measuring 15x30 cm and a beam measuring 15x15x30 cm. The tests carried out were testing the compressive strength and flexural strength at the age of 28 days. The results showed that the highest compressive strength was at the addition of 10% latex with a value of 9.96 MPa. While the highest flexural strength value obtained was 3.20 Mpa at the addition of 10% Latex or. From these results it can be seen that the addition of latex has not been able to improve the quality of concrete and has not been able to increase the compressive strength or flexural strength of concrete. So that these results can be used as research development or concrete production.

Abstract

The function of the foundation as a substructure that transmits the load received from the upper structure of the building into the foundation makes the foundation have an important role. The strength of the foundation is something that needs to be planned properly. This planning aims to plan the foundation for the Permata Indah Building, Nganjuk Regency, which will later be used as a boarding house building. Planning that is carried out includes selecting the type of foundation, calculation of dimensions, and foundation reinforcement. Based on soil investigation results, the foundation type pile was chosen because the hard soil was located at a depth of 17 m. The method used to calculate the bearing capacity of the pile includes the Meyerhoff, Begemann, and Trofimankove methods. With a diameter of 30 cm and 4 poles, the carrying capacity of group piles (Pg) was obtained using the Meyerhoff method of 224.60 tons, the Begemann Method of 199.59, and the Trophimankove Method of 259.36 tons. From these results, the group pile bearing capacity value is still greater than the value of ƩVu= 146.28 tonnes. Meanwhile, for a single pile settlement Se= 2.13cm <Sijin= 3 cm SAFE and a pile settlement group Sg= 3.98cm.

Abstract

The foundation is a lower structural element that serves to with stand the load of the upper structure. Pile foundation is one type of deep foundation, which is widely used in the construction of buildings. Pile foundation used in hard soil cases is located at a very deep depth. Abipraya Building is a building located in kediri regency which later functioned as a rural office. This study aims to increase the carrying capacity of pile foundation in the abipraya building project using the begemann method. Calculations carried out include the calculation of loading, carrying capacity, buckling factor and determination of foundation point.  Based on the calculations obtained the results of axial load (sigma Vertical Ultimate) Σνυ of 99.70. with a single-pole carrying capacity of 38.89 tons and a group pole carrying capacity of 117,917 tons. These results will be planned the foundation of the stake with a diameter of 30 with a depth of 8 meters, amounting to 4 poles. Calculation factor buckling results in 194.14 kg/cm2 smaller than the allowed maximum 2400 kg/cm2. Thus, with the known components of the planning of the pile foundation, it can be used as a reference in the construction of the abipraya building.

Abstract

Concrete is a vital component of construction. One of them is lightweight concrete consisting of a mixture of coarse aggregate, fine aggregate, cement which is united by water in a predetermined ratio. Lightweight concrete is concrete which has a weight of less than 2000kg / m³, lightweight concrete usually uses aggregate or lightweight material so that the concrete produced also has a light specific gravity. Waste cigarette filler waste is a waste that is difficult to recycle. Cotton filter cigarette butts are cotton-based fibers that are lightweight, porous and easily absorb water. For the use of this waste as a substitute for overall coarse aggregate, research needs to be carried out, namely the amount of compressive strength produced by replacing coarse aggregate from cigarette butts waste, job mix used according to SNI K-125 by completely replacing coarse aggregate with cigarette butts waste, Job mix for 1m³ concrete consists of 276 kg of cement, 214 liters of water, 148.62 kg of cigarette butts, and 828 kg of sand. From the above research, the highest compressive strength at 28 days reached K-115.56, which means that the target for concrete paving has reached K-100. As for the absorption, value is quite high from consecutive tests for ¼ hours, 1 hour, 4 hours, and 24 hours produced an average value of 0.116 liters, 0.269 liters, 0.374 liters, 0.699 liters. The results of the study of concrete density with a coarse aggregate of cigarette butts waste reached an average of 1831.11 kg / m³, for the study the pore figures yielded an average value of 0.2854, then the results of the porosity values obtained an average of 0.222016.                                                 AbstrakBeton merupakan komponen vital pada suatu konstruksi.

Abstract

Proyek konstruksi merupakan penumbang terbesar adanya kecelakaan kerja. Salah satu penyebab kecelakaan kerja adalah unsafe action. Tindakan unsafe action disebabkan oleh para pekerja yang kurangnya peduli lingkungan/kebersihan. Dengan alasan tersebut maka peningkatan peduli lingkungan merupakan salah satu upaya dalam mengurangi kecelakaan kerja maupun kenyamanan lingkungan sekitar. Pengabdian ini dilakukan pada salah satu proyek rumah sakit di nganjuk. Tahapan pengabdian ini diantaranya identifikasi, sosialisai dan evaluasi. Hasil dari pengabdian ini adalah adanya peningkatan kepemahaman dari 11 unsur lingkungan yang ditanyakan dan dihadiri oleh perwakilan pimpinan kontraktor/konsultan. Pengabdian ini memerlukan komunikasi / tindakan yang berkelanjutan agar peningkatan lingkungan lebih baik lagi / peningkatan unsur baru dalam lingkungan.
