Analisis Kelayakan Finansial Internal Rate of Return (IRR) dan Benefit Cost Ratio (BCR) pada Alternatif Besaran Teknis Bangunan Pasar Cinde Palembang

This paper discusses the feasibility analysis of financial internal rate of return (IRR) and benefit cost ratio (BCR) on Cinde market which is one of the oldest markets in Palembang. Feasibility analysis  is done by creating two design alternatives which  were different  from existing alternative and assumes revenues received later. By creating different alternatives, land area, kiosks and parking lot,  alternative A has a 26,08% IRR and BCR 1.18. This alternative makes buyers much easier to go directly to the floor or parking lot they want to go to. Effect of technical quantities of market building will greatly affect the financial feasibility with reference to the existing standard

PENGARUH PEMADATAN BETON SEGAR TERHADAP KUAT TEKAN BETON

Concrete is construction material which frequently used in the field of civil engineering. In constructing process, concrete material is a part of building structure with some superiorities, among others, are: high compressive strength, being able to be formed as needed, no serious maintenance needed, and relatively fireproof and weatherproof. Various studies and experiments in the field of concrete as part of efforts to improve the quality of concrete. One way to increase the strength of concrete is to increase the compacting, which minimizes pores or cavities formed in the concrete. The additive material used in this study is fly ash. Fly ash is a waste of coal burning. The fly ash in this study was taken from PLTU Bukit Asam Tanjung Enim. The type of fly ash used is fly ash F class, which is the result of burning of coal of anthracite/bituminous with low content of CaO, less than 10%.  Maximum density of concrete can be attained by compacting the fresh concrete. The main goal of compaction of the fresh concrete is to eliminate air cavities and to achieve maximum density. The concrete compressive strength will increase if the density of concrete also increases. The compaction of 75 kg / cm ² with no fly ash added   generates  the strength of compressive of concrete  41.08 MPa. The greater compaction of fresh concrete is given, the more compacted the concrete will be, surely the  weight of the concrete content will get heavier. This is because the concrete that has been compacted  will be more compacted, so that air pores in the concrete will be smaller than normal concrete. The maximum weight of concrete of compaction   75 kg / cm ² with no fly ash added is  2.518 ton / m³. In this study the crack tend to form columnar type

PERBANDINGAN METODE PEMBEBANAN VAKUM DENGAN PRAPEMBEBANAN UNTUK MEMPERCEPAT PROSES KONSOLIDASI ( 17-23 )

Palembang Toll Development Project - Simpang Indralaya is built on swamp land. The subgrade of this road is soft clay soil that has low bearing capacity of soil. Low bearing capacity of the soil will cause severe damage to the pavement on the soil heap. Therefore it is necessary to strengthen the base soil to be able to withstand and avoid sliding because it does not decrease.In this final project, there will be comparative analysis of 2 (two) alternatives to improve the embankment in reaching the same degree of consolidation. The first alternative is traditional preloading method and second alternative is vacuum preloading method.From the calculation results, obtained by using vacuum preloading method, the time required to achieve the same degree of consolidation can be shorter than the traditional preloading method
