Abstract

In 2013, Kerasian Island experienced erosion, which caused the coastline to shift ± 100 m from the initial condition. In some places, the retaining wall has been damaged so that it does not function properly. An effort is needed so that the beach does not experience abrasion and is safe for the activities of residents or tourists who come there. Before deciding on an alternative, first of all, is to choose from many erosion prevention methods that are suitable for the beach conditions there. The selection was conducted using the Analytical Hierarchy Process (AHP) method. Based on the AHP method, groin combined with mangrove planting is a suitable method to be applied on Kerasian Island. The groin design refers to the Pd T-04-2005-A guidelines issued by the Indonesian Ministry of Public Works. The dimensions of the design results and groin material used are explained in detail in the paper.

Abstract

Project cost control is important in the project management process to avoid losses. Project control can be carried out in terms of cost and time. One way to control project costs is to choose the design, materials to be used in the project, and the implementation methods to be used. The objective of this study is to obtain an alternative structural design with an optimal construction cost of structural work by considering the use of concrete quality in reinforced concrete structures, column spacing and cross-sectional dimensions of structural elements. The existing design is to use quality K250 concrete. In this study the cost analysis of the concrete structure, foundation, tie beam, beam, column and ring beam work results from value engineering. The stages of research start from the design information stage, the creative stage that is determining the design alternatives and the analysis stage. The analysis was carried out by structural analysis using SAP2000 and analysis of concrete work costs. The results of the analysis of alternative designs namely reducing the dimensions of the cross-section, using K300 quality concrete, eliminating structural elements that do not need to meet in the calculation of the structure. The next step is to calculate the cost of the concrete work. Concrete structure work when using an alternative design that is to reduce the dimensions of the structure, change the quality to K300 and eliminate unnecessary elements that can save costs by IDR.35,956,756.00 or 37.02%.

Abstract

At the smelting plant of PT Smelting Company Gresik produces waste in the form of copper slag. Copper slag waste has several advantages including increasing concrete compressive strength, reducing heat hydration, increasing resistance to sulfate in seawater, reducing alkali-silica and chloride attack. Probolinggo power plant there is the waste product from burning coal. The waste is divided into two types. The flying waste is fly ash obtained by being captured by other particle filtration equipment before the exhaust gas reaches the coal chimney. Whereas the waste that goes down is called bottom ash. This study uses copper slag waste as a partial replacement for sand with fly ash as a partial replacement for cement. The variant used are 40% copper slag, 40% copper slag + 5% fly ash, 40% copper slag + 7.5% fly ash, 40% copper slag + 10% fly ash. Copper slag comes from PT. Smaleting Company Gresik, while the fly ash from PT. Paiton. Tests carried out at PT. SCG Readymix. Test carried out at the age of 14 days, 28 days and 56 days. Normal concrete compressive strength was obtained more than 42 MPa, the highest compressive strength at a variation of 40% copper slag + 10% fly ash with compressive strength of 58.13 MPa at the age of 56 days.

Abstract

The use of pavement is increasing as an impact of urban development. The pavement of the land surface is very influential on increasing surface runoff. The surface runoff will cause flooding and inundation if the drainage system is not good. The use of pavement that can reduce runoff is needed, to reduce the occurrence of floods. This study aims to determine the effect of the land surface on the value of the surface runoff coefficient (C). The material used is in the form of paving blocks with the fill of grass between paving blocks. This research was conducted using a rainfall simulator. The material used is brick-shaped paving blocks of size 20 x 10 x 8 cm with a variety of brick stacking patterns and woven mats combined with mini elephant grass with a mix ratio of 75%: 25%. The measurement results are rainfall intensity, runoff volume, and surface runoff coefficient (C). The results showed that the addition of mini elephant grass had an influence on the value of the runoff coefficient. In paving blocks without the fill of mini elephant grass has a greater coefficient. The runoff coefficients produced include: soil runoff coefficient values ranging from 0.39 - 0.44, paving blocks for brick stacking runoff coefficients range from 0.42 - 0.46, paving blocks woven mat ranges from 0.41 - 0.45, paving blocks brick stacking patterns with the fill of mini elephant grass runoff coefficient ranging from 0.40 to 0.45, and paving block woven mat patterns with of mini elephant grass runoff coefficient ranging from 0.36 - 0.41.
