Innovation within Small-Medium Scale Contractors in Indonesia
Get PDFIn order to survive within the industry, small-medium scale contractors are required to be adaptive. However, many obstacles have been experienced by this group to deal with. The term of survive can be interpreted by doing continuous innovation. This research was conducted to investigate the innovation issues related which possibly could triggering or canceling the innovation within small-medium scale contractors. Literature study was conducted as a primary and followed by a field research using questioners. From the research it was found that the main motivation and orientation within innovation processes was the competitiveness among the group of contractors and followed by the attempt to respond the recently industry environment. However, they tend to avoid the change in their business concept. Finally, the availability in source of funding was highlighted as the main factor which might brough innovation initiative successful. 
Concrete Asphalt Marshall Stability Using Concrete Objective Waste
Get PDFThe road is one of the most important infrastructures. The community needs it because the road functions to connect the source of production. Asphalt is an aggregate binding material in road pavement construction, which plays an important role in determining road pavement performance. Road Pavement, in general, uses materials that are still fairly common. This study uses a fine aggregate of crushed concrete specimens. The method used is an experiment on the addition of concrete test specimens with percentages of 10%, 20%, 30%, 40%, and 50%. Marshall method which is the basis for calculating the stability value and flow. the results of 5 Marshall test samples of asphalt concrete mix utilizing concrete waste obtained the characteristics of the average value of the study that all had met Highways' requirements at a VMA value of 18.22%, a value of 4.22 VIM.%, VFB value 75.04%, STABILITY value 4806 kg, FLOW value 3.24 mm, and Marshall Quotient (MQ) value 14958.1 kg / mm
A Study of The Density of Motor Vehicles In Front of Bunda Hospital Margonda Depok Against Noise Pollution
Get PDFDepok became a pilot as an orderly city with traffic arrangements and diverse patterns of population movement. The diversity of the city residents' trips has resulted in an increasingly diverse population passing through the region. Population mobility also requires adequate transportation facilities and infrastructure. This study aims to obtain traffic data and the level of noise pollution caused by the speed of motor vehicles (SPM, MP, MAU) in front of the Bunda Hospital Margonda Depok. The calculation and analysis obtained are on the equation with the first largest R value on the second day of the third point study (Sound Level Meter 3), with a contribution of 50.50%. As equation, y = 73.824 + 0.030x1 - 0.020x2 - 0.324x3, the addition of motorcycle density is 0.030 and the reduction in private car density and public transport car density is 0.344, the noise pollution level will be reduced by 0.314 dBA in SLM3. The second largest R value with motorcycle density, private car density and public transport car density has a moderate effect on noise pollution in the second day of the research point (Sound Level Meter2) with a contribution of 48.50%
STRONG TEST PRESSURE CONCRETE USE OF ASBEST WASTE
Get PDFConcrete is a significant and most dominant material used in building structures. Concrete consists of a mixture of cement, aggregate, water, and added ingredients. Concrete said material has an essential role in making concrete because it can change the real properties to suit the needs. Li, asbestos is a concrete-added material that can reduce the use of cement and produce concrete with absolute consistency. The purpose of this study was to determine how the effect of adding asbestos waste to cement. The method used is an experimental method based on previous research. The specimen used was cylindrical with a diameter of 15 cm and a height of 30 cm. The percentage variation of asbestos waste addition is 0%, 50%, and 100% of the weight of cement used. Typical concrete test results obtained an average value of 22.08 MPa, a 50% percentage produces an average compressive strength of 21.32 MPa, and a portion of 100% provides a compressive strength of 22.93 MPa. Then the results of the then actual strength test have increased in the percentage of asbestos waste 100%

Existence of Licence, Infrastructure, and Energy Recources in Increasing Small Business Capacity in Sidoarjo District in The New Normal 4.0
Get PDFThis research was conducted in Sidoarjo Regency which has a lot of potential to grow and develop small businesses in three regions that is Krembung, Jabon, and Tulangan. The problem is one of the potential growth and development of small business activities in these three districts which has been supported by increased speed in business licensing, adequate infrastructure and the availability of renewable energy sources (gas) for smooth running and assistance for small businesses in the regions. To prove this, this research requires an increase in licensing, provision and improvement of infrastructure, and energy resources that can support its development activities for small business growth in the new normal 4.0. Of the three regions that were the object of research, at random there were 173 small business owners who were subjected to data collection in the field. As a basis for making decisions in an effort to overcome the above problems, the method used in this study is Crosstabs analysis, to test and determine whether there is a linearity between the potential for small business development with the availability of licensing management facilities, infrastructure provision, and supply of energy resources. the main pillar of the smooth running of small businesses in developing business activities, distribution and marketing of their products. From the test results, it turns out that the three facilities mentioned above, all have a linear relationship with the growth of small businesses in the three districts
