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. Salah satunya beton ringan yang terdiri dari campuran agregat kasar, agregat halus, semen yang dipersatukan oleh air dengan perbandingan yang telah ditentukan. Beton ringan adalah beton yang memiliki berat kurang dari 2000kg/m³, beton ringan biasanya menggunakan agregat atau bahan yang ringan sehingga beton yang di hasilkan juga memiliki berat jenis yang ringan. Limbah puntung rokok fillter adalah suatu limbah yang sulit untuk di daur ulang. Puntung rokok fillter berbahan dasar kapas yang merupakan serat yang memiliki sifat ringan, berpori, dan mudah menyerap air. Untuk penggunaan limbah ini sebagai pengganti agregat kasar secara menyeluruh perlu diadakan  penelitian yaitu besarnya kuat tekan yang di hasilkan dengan penggantian agregat kasar dari limbah puntung rokok tersebut, job mix yang digunakan sesuai SNI K-125 dengan mengganti sepenuhnya agregat kasar dengan limbah puntung rokok,,job mix untuk 1m³ beton terdiri dari semen 276 Kg, air 214 liter, puntung rokok 148,62 Kg, dan pasir sebanyak 828 Kg. Dari penelitian di atas diperoleh nilai kuat tekan pada umur beton 28 hari tertinggi mencapai K-115,56 yang berarti telah mencapai target untuk paving beton sebesar  K-100. Sedangkan untuk nilai absorsinya cukup tinggi dari pengujian berturut-turut selama ¼ jam, 1 jam, 4 jam, dan 24 jam di hasilkan nilai rata-rata  sebesar 0,116 liter, 0,269 liter, 0,374 liter, 0,699 liter.

Abstract

The science of concrete in the present era has developed. Research on efforts to improve the properties and performance of concrete has been carried out a lot. One of them is modifying a concrete mixture with fly ash as a substitute for some cement and coconut shell charcoal as a substitute for some sand. The chemical properties contained in fly ash are 80% in the form of silica and alumina. The purpose of this study was to determine the slump value and the compressive strength value of the test object added with fly ash with variations of 3%, 6%, 9% of the weight of cement, and 3% baroque coconut charcoal by weight of sand. This research method is experimental, which refers to the Indonesian National Standard with a test object cylinder size 15x30 cm totaling 12 samples tested at the age of 28 days with a quality plan fc'16.60 Mpa. The results showed that the highest slump value was obtained in the test object variation 3, namely 7 cm, while the average compressive strength of each variation has exceeded the quality of the plan with the highest value obtained in variation 2 with a compressive strength value of Fc'24.9 Mpa.

Abstract

Foundation is a lower structure that serves to withstand the load of the upper structure. One type of foundation inside is mini pile foundation. Mini pile foundation is widely used in construction with light to heavy loads. This study aims to plan the foundation of mini pile with carrying capacity and dimensions of the stake that is safe for the PT building's lower structure. MAJU JAYA, which will be used as an office. Based on the data of sondir test results obtained from the field on the building project's construction, the stake's foundation will be planned using the mayerhoff method. This plan obtained the results of axial load (sigma Vertical Ultimate) Æ©vu of 145.56, the carrying capacity of a single pole of 31.17 tons, and the group's carrying capacity pole of 173.84 tons. This result will be planned the foundation of mini pile with dimensions of 20x20 with a depth of 8 meters a number of 8 poles.

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 Æ©Vu= 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 bridge becomes a vital building in living today, which is connecting two areas that separated land. The Golo Bridge also connects the two regions, Blitar and Tulungagung. The Golo Bridge in Tumpakoyot Blitar is part of a national project to build alternative and fast routes in the Southern Java alternative route. The existing Golo bridge is a bridge with a PC-I Girder structure 40 m long and 11 m wide. This research aims tore-plan or modify it to become a bridge with a steel plate girder structure by dividing it into 2 spans, collecting the existing data to be processed in the analysis calculation. It's started with determining the dimensions of the initial structure, giving loads, controlling the structure's ability, also for the abutment & pier. The calculation shows that the dimensions of the steel plate girder have a profile of 2500. 700. 14. 40 mm. Meanwhile, the abutment has a total height of 5.70 m, a width of 4.50 m, and 9.50 m. The bridge pillars have a total height of 6.20 m, a width of 6.20 m and a length of 9.50 m. These results show that the structures is able to support the working loads.

Abstract

The slums in Sidoarjo city are caused by people who ignore the cleanliness of the environment. The number of people who dispose of waste, household waste, or production waste in the channel causes the reduced function of drainage channels. This study aims to determine the capacity of existing channels in the flood area of Sidokare and Lemahputro slum, Sidoarjo. The method used uses a quantitative descriptive method—hydrological data obtained from rainfall recording stations for ten years. The data was then analyzed using rational methods to calculate the discharge of flood plans when resetting the 10-yearly. The hydrology and hydraulic analysis calculation results obtained plan discharge (Qr) of 0.092 m3/s and existing discharge (Qs) of 0.032 m3/s. These results showed the existing channel condition could not accommodate the discharge of rainwater runoff, so there needs to be redimence of the channel. From the analysis of the dimensions of drainage channels conducted, obtained a new channel in the form of Box U-Ditch with a channel depth (h) 0.50 width under the channel (b) 0.40 m, with channel discharge plan that 0.128 m3/s can accommodate.
