Abstract

This study aims to determine the effect of superplasticizer usage on concrete compressive strenght with variation of water cement ratio using subdivided crude aggregates (split). This research cylindrical test object with diameter 15 cm and height 30 cm. Compressive strength concrete design fc’ 35 MPa, with variation of water cement ratio W/C 0,4; 0,45; 0,5 and using Superplasticizer Sikament LN materials 0,5% of the weight of cement and slump value 12 ± 2 cm.The result of research showed an increase the value of concrete compressive strength with the addition of superplasticizer. The average of concrete compressive strength without the addition of superplasticizer and variation of water cement ratio W/C 0,4; 0,45; 0,5 at 28 days in a row is 36,14 MPa, 34,73 MPa, 29,82 MPa. While the value of concrete compressive strength with the addition of superplasticizer increase to 39,73 MPa, 37,18 MPa, 31,23 MPa.

Abstract

This research was conducted to assess the Level Of Service (LOS) pedestrian path around the Tanjung Barat Station area. In addition, to see in terms of comfort and security in reaching a TOD concept area. For this reason, a model of pedestrian design is needed so that track users can enjoy the pedestrian pathway feeling comfortable and safe. The results of this study indicate that the level of pedestrian service on the Tanjung Barat Raya road and on the road in Lenteng Agung raya: For the Tanjung Barat Raya road the LOS index is categorized as "B" while the Lenteng Agung Raya road is in the LOS index in the "C" category. And for the prediction of the next 5 years, LOS is categorized as "B". This indicates the need for improvements in terms of supporting facilities for pedestrians on the two St. Western Cape. This indicates that the pedestrian support facilities need to be improved which will have an impact on the increasing number of pedestrian users around the West Tanjung station for the next 5 years.

Abstract

This research is a analysis of capacity and level of service at Jalan Raya Bogor segment Cisalak Market in existing condition with a purpose to optimize it based on rule that already assigned in Highway Capacity Manual (MKJI) year 1997. The result of analysis showed that capacity of Jalan Raya Bogor segment Cisalak Market can be optimize, from 3307 smp/hour to Jakarta become 3596,36 smp/hour. The direction to Bogor also having incresement from 2696,52 smp/hour become 3329,04 smp/hour.The degree of saturation and level of service direction to Jakarta can be upgraded from 0,47 (C) become 0,43 (B) at Sunday morning if its does not affect by the activity of the market, also in Monday morning which is restrained in LoS E with Ds 0,85 become 0,79 or in LoS D and in Monday afternoon with LoS D (0,76) become C (0,69). Meanwhile direction to Bogor can be upgraded in Saturday afternoon from LoS C (0,61) become B with the number of Ds 0,49, then in Sunday morning and afternoon also Monday morning respectively can be upgraded from C to B. Last, in Monday afternoon into LoS C with number of degree of saturation is 0,62 from LoS D with 0,76.

Abstract

This inquiry aims to investigate whether the use of green mussels shell powder as an alternate filler in Laston mix can meet the Marshall parameter or not. Method used in this inquiry is experimental method that examines Marshall parameter at various percentages of green mussels shell powder use in which their level are 0%, 6,5%, 7,5%, and 8,5% as an alternate of half of filler. The experiment of green mussels shell powder is generate a maximum level of filler at 7,5% percentage with stability value in 987,478 kgs, flow value in 3,70 mm, Marshall Quotient value in 266,738 kgs/mm, Void in Mineral Aggregates value in 17,597%, Void Filled with Bitumen value in 71,958% and Void In the Mix value in 4,709%. By this result, it can be concluded that green mussels shell powder can be used as an alternate filler in AC-WC asphalt mix for heavy traffic road with 7,5% percentage of filler level.

Abstract

The purpose of this research is to determine the Superplasticizer Sikament LN as a added of cement in compressive strength test in an effort to determine the maximum compressive strength of the concrete. This research was partially adding cement with Superplasticizer with a variety of percentages 0%, 0,5%, 1%, 1,5%, and 2% of the total weight of cement. Concrete design f’c 35 MPa, W/C 0.4, 12±2 cm slump, amount of sample was 30 (3 samples for each variation for concrete life of 7 and 28 days). The results showed that 0,5% variation of Superplasticizer reached the average concrete compressive strength is 43,5 MPa; 1% variation of Superplasticizer is 42,56 MPa; 1,5% variation of Superplasticizer is 40,86 MPa and 2% variation of Superplasticizer is 40,2 MPa. The maximum concrete compressive strength contained 0,5% variation of Superplasticizer.
