Abstract

Green Public Space is an open social facility where all people can use it. The green public space it self is functioned as a social facility, such as children's playground, place to relax, and a place to exercise, green public space can also be used as a water catchment area that can be used for reducing the occurrence of inundation and flooding. It is expected that the presence of green public space in the housing environment can improve the quality of the surrounding environment, as the identity of this housing, and can also be added value for BRD Residence housing. Designing a comfortable green public space for residents to visit in particular and residents of Pringrejo Village in general and to find out how much the budget plan is needed to build a green public space in the BRD Residence housing. From the results of the survey pad a measurement of the study location obtained a land area of 1148 m2 with a length of 82 m and a width of 14 m, while from the results of analysis, this green public space is a type of park RW. In calculating the budget plan for planning the green public space or park RW, the total cost needed for the construction of green public space is Rp 410.000.000,00 consisting of 5 jobs, including; paving work of Rp 91.618.355,55, playground work of Rp 67.983.960,74, jogging track Rp 45.031.556,25, gazebo work in the amount of Rp 151.351.789,08, and in the flower garden work of Rp 54,018,901.72.Keywords: Green Open Space, Planning, Costs.

Abstract

Concrete added material is an ingredient other than a constituent of concrete added to the concrete mix, before, immediately, or during concrete stirring. Added ingredients that are mixed on the concrete mix are intended to change one or more of the concrete properties while still fresh or hardened, for example the nature of the workmanship is easier, the nature of binding faster, get more plastic fresh concrete, faster rate of strength or compressive strength which is generated larger. The added ingredients used are ashes baggase (baggase ash) and supperplasticizer, and in this study itself aims to find out how much influence the addition of bagasse ash and superplasticizer sikament NN to the compressive strength of concrete, so it can be known how the optimum percentage of bagasse ash cement that produces maximum compressive strength of concrete. Planning of concrete mixture in this research using trial method by taking 5 variation of ash bagasse, 0%, 5%, 10%, 15%, 20% from cement weight and 4 variations of superplasticizer addition that is 0%, 1% , 1.5% of the weight of cement. Testing of concrete compressive strength as much as 60 specimens carried out at the age of 28 days. Based on the result of this research, it can be concluded that maximum compressive strength value in concrete is found on ash bagasse 15% and superplasticizer 1.5% with an average compressive strength of 34,991 Mpa or an increase of 17,790%. From the results of this study, it can be concluded that the use of bagasse ash and superplasticizer can increase the compressive strength of concreteKeywords: Compressive strength, Baggase Ash, Superplasticizer.

Abstract

Semarang is one of big city in Indonesia with a lot of activities in everyday. As the capital city of Central Java Province, Semarang City gives an active contribution which be related with the movement as human, goods and services. The movements that occurs to form knot of traffic so that give rise to traffic jam as seen on Jatingaleh Street. Because of this, it needs to be done an improvement of the capacity of a flyover and transportation management that supports it. This research aims to given flyover models based on transportation management and the policies are related in the transportation system so that is expected to overcome the traffic jam and give benefits which is in lin with the development of the city. In this research, do an analysis of Jatingaleh Street Semarang before availability the flyover and after availibility the flyover than be managed which is conformed with traffic conditions of Jatingaleh Street. Based on the calculation, after the flyover and be done manage reduction in the volume of vehicles was reduced by 4,61 % for light vehicles (LV), 2,63% for heavy vehicles (HV) and 86,59 % for motorcycle (MC) .

Abstract

Infrastructure development in Indonesia experiences rapid development every year, including in Pekalongan City. Infrastructure development in Pekalongan City starts from the construction of roads, buildings, public facilities, and so on. The Pekalongan City Government has made an alternative that is in accordance with the above conditions, namely by constructing offices to improve or meet the needs of public facilities and realize sustainable infrastructure progress. The construction of existing high-rise buildings must be properly planned in accordance with applicable regulations. Based on SNI 2847-2013, regarding calculation procedures for buildings, it is explained that the loads that must be calculated for planning a structure are dead loads, live loads, wind loads, earthquake loads, and combinations of these loads. The building under review is a two-storey office building with reinforced concrete construction. The analysis is carried out with the help of the SAP computer program. Before analyzing, first make a working drawing design with the help of the Autocad program. The final results in this study are in the form of dimensions of structural elements that are planned to be strong and resistant to loads and economical in terms of cost. While the analysis of the main structure in the form of plates, beams, and columns.
