Refinement Method of Retaining Wall (L-Shape Concrete) and CCSP Design in Kalimas Quayside Kademeter 1200-1400 Project
Full text linkAs one of the state-owned enterprises (BUMN), PT Pelabuhan Indonesia III (Persero) Regional Jawa Timur has demanded to obtain the considerable revenues using the limited maintenance funds for port facilities. One of the roles of Engineering Division includes the availability of port facilities that support operation division, so it is necessary to check and maintain the facilities. In consequence, the estimated cost and time of project carried out effectively to mitigate the risk level in the future in order to achieve the main objectives. One of the biggest revenues in the port sector is on the quayside facility services, therefore, maintenance of these facilities needs to be prioritized. The final project provides an analysis of cost and time calculations using the method of repairing the retaining wall (L-Shape Concrete) and the CCSP (Coruggated Concrete Sheet Pile) method for repairing damage to Kalimas Kademeter Quayside 1200-1400 with damage length of 176 meters and width of 9 meters. Based on the observation of cost and time analysis, the estimated cost of using the L-Shape Concrete repair method is much cheaper than using the CCSP (Coruggated Concrete Sheet Pile) method, but the actual project period is much longer. Finally, the selection of repair methods can adjust to the necessity of cost and time aspects, as well as the methods of project
Comparation Study of the Use Naftalena from Coal Tar Waste with Camper Napthtalene as Concrete Admixture
Full text linkConcrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate, and water, with or without additives (admixture).
The naphthalene superplasticizer used comes from distillation of coal tar and a little from the rest of petroleum, but there is also camphor naphthalene. Where camphor grains contain 250-500 mg of naphthalene. Naphthalene is mostly produced from coal tar distillation, and a little from the rest of the fractionation of petroleum, by the molecular formula (C10H8) and in the form of two unified benzene rings. This compound is volatile, volatile even in the form of solids. The vapor produced is flammable.
The purpose of this study was to determine the effect of the use of naphthalene from coal tar waste with camphor naphthalene as concrete admixture, and determine the effect of naphthalene from coal tar waste with camphor naphthalene on concrete toughness, density, water absorption, of concrete compressive strength. It is expected that the use of naphthalene can reduce the use of cement, and reduce water use. But it does not reduce the strength of the concrete so as to reduce costs in making concrete. The variations in the use of camphor naphthalene and coal tar naphthalene are 20%, 30%, 40%

Case Study of Delay Construction Projects in Bidau Dili Timor-Leste Bridge
Full text linkThe process of implementing development projects has many obstacles that were not predicted beforehand resulting in delays in project completion which have an impact on increasing the cost of project implementation. sometimes the project is not completed in accordance with a predetermined schedule that may be caused by certain factors. Various ways can be done to anticipate and be a solution to the delay. The purpose of the study is to analyze the factors that influence delays in bridge construction projects in Bidau Timor - Leste and how to anticipate delays in project work. The research method used is descriptive method by observation and direct interviews. So that there are several dominant factors that influence the delay of the Bidau Timor-Leste bridge construction project, including the types of weather, material and financial. To anticipate delays in construction projects, it is necessary to do a work contract in accordance with the contract law in which all matters are regulated, so that the anticipation, mitigation and accountability are clear. Identification of the application of overcoming delays in the Bidau Timor-Leste bridge construction project if viewed from the side of the existing contract there are still shortcomings, so it needs to be improved in terms of working contract documents and refer to the contract law

Based on the increase of population used is 12.8% and the population is 10 years (2018-2027) for 2.395.75 inhabitants. The balance of clean water needs in urban clean water services
Operational Plan For The Numbers Using Fast Mass Transport Trem In Surabaya
Full text linkTraffic jams often occur in the city of Surabaya. Due to the increasing population and the desire to have private vehicles, this has led to the need for adequate additional road capacity. However, the frequent increase in road capacity is not enough with the very high growth of road users. Therefore, the Surabaya city government planned an alternative route to reduce the congestion that occurred, one of which was building a rapid mass transportation, the tram, the construction of the tram itself was still in the planning stage, requiring a study of the influence of operational plans on public interest in trams, specifically for motorcyclists. What factors can make motorbike riders divert to the tram. One way to find out how much interest motorbike riders have is to use multiple linear regression methods which require data from road users. Questionnaires are needed to retrieve data and collect samples consisting of 200 respondents. In this study the location of the deployment is in the area that trams are going to plan for, starting from Joyoboo - Jl.Raya Darmo - Urip Sumoharjo - Jl.Basuki Rahmat - Jl.Embong Malang - Jl.Blauran - Jl.Bubutan - Tugu Pahlawan - Jl. Indrapura - Jl. Rajawali. While going south will pass Jl. Heroes - Jl. Gemblongan - Jl, Tunjungan - Jl. Governor Suryo - Jl. Panglima Sudirman - Jl. Urip Sumoharjo - Jl. Raya Darmo - Terminal Joyoboy
Technical Evaluation and Boezem Bratang Operation Patterns In Surabaya
Full text linkSurabaya is the second largest and most populous city in Indonesia and is inseparable from the problem of flooding which is still flooded the area of East Surabaya.Flooding is caused by Bratang boezem unable to accommodate rainwater discharge. Boeang Surabaya has an area of 19,900 m2, has two systems namely flood gates and flood pumps. The floodgate system will work to drain the boezem bratang water to wonokromo river if the water elevation at Wonokromo River is at under the elevation of Bratang boezem water and flow Gravitatively while the pump system will work if the floodgate system is no longer functioning. To overcome the problem of flooding in the region, it is necessary to conduct hydrological and hydraulics analysis by performing boezem routing to determine the Boezem capacity whether it can accept the planned rain discharge. a depth of 3 m is unable to accommodate a maximum flood discharge period of 2.5 and 10 years. so it is planned to increase the boezem depth which was originally 3 m to 4.6 m, and increase the pump capacity which was originally from 10.5 m3 / s to 14 m3 / s.From the plan, after the hydrologic and hydraulics analysis using Boezem routing, Boezem has been able to accommodate the planned rain discharge
Analysis and dynamic behavior of portal structures due to reciprocating machine
Full text linkreciprocating engine consists of two driving parts, piston and rotor, when the engine start these two parts move with a certain frequency, resulting in vibrations in the structure. dynamic analysis of the structure aim to find out how the structure behaves due to vibrations generated from the machine, whether the structure is safe for the machine and humans around the machine due to the amplitude of displacement, velocity, and displacement from structure. This dynamic analysis is carried out with the help of SAP 2000 v20.20 software with a dynamic load in the form of a reciprocating compressor operating with a frequency of 49.16 Hz. In this final project, the machine foundation uses a table top type with 1x1.7 m column dimensions and 1.3x1.6 m beams. From the free vibration analysis, the result is a natural frequency structure, from the first ten modes the structure is declared safe from resonance However, in this study the displacement and velocity of structures that occur in the zone B & C while the acceleration into the safe category based on applicable standards. This means that the structure is safe for humans who are around but are not safe for the product and the machine itself if it operates for a long time continuously
