In the AC-WC mixture, the filler is the material that significantly influences the characteristics and quality of the asphalt concrete mixture. Fillers can come from environmentally friendly materials. One material that is often found is shell waste. The method used in this research is quantitative descriptive. Based on research conducted, the shells used to meet the requirements as filler with a percentage of passing sieve no. 200 was 75.12% and the gradation composition of the mixture for AC-WC was 2% for shell filler, 50% for stone ash, 33% for screening, and 15% for the split. Meanwhile, the asphalt used in the AC-WC mixture is PG 76 Asphalt. Based on the test results, it was found that the characteristics of PG 76 asphalt were not too flexible and tended to be stiff, resistant to hot temperatures, and had homogeneous properties. In testing the AC-WC mixture, Marshall’s results obtained an optimum asphalt content of 6.3% with a stability value of 2877 kg and a flow value of 2,716 mm. This shows that the use of shell filler can increase the stability value of the mixture, however, a high stability value accompanied by low flow indicates that the mixture has a stiff pavement and will be brittle. Meanwhile, for the runway pavement thickness design at Nusawiru Airport using the FAA method and FAARFIELD software, a total thickness of 14 inches was obtained with details of a Surface Course thickness of 4 inches, a Base Course thickness of 6 inches, and a Subbase Course thickness of 4 inches.

Indonesia as one of the member countries with the largest GDP in the world. has its own challenges to be able to maintain and even increase GDP. In fulfilling this, the government is still trying to increase the provision of infrastructure in Indonesia to support construction developments in industrial areas and work together with the private sector (investors, contractors and operators) to realize the provision of these areas. The process of developing industrial estates this requires tools to analyze risks. In reality it is very difficult to control the emergence of risks that cannot be resolved or overcome, starting from identifying risks to finding ways to reduce their impact on achieving project objectives regarding the level of risk involved. Risk factor analysis is seen from the magnitude of the impact (impact) and the probability (probability) of the risk event. Based on previous research, a summary is made by separating the risk into 2 stages of risk. The first is the risk during pre-construction and the second is during the construction stage. The risk weights and risk categories are obtained from the results of risk identification, the risks identified in development projects in the industrial area are 28 risks and 8 types of risk sources. It is the risks that have quite a large value that are the most dominant risks that occur in development projects in industrial estates, based on the results of an analysis of the frequency of occurrence of risks and based on the impact of the risks that occur. Risk of tender process error, contract document error, standardization differences, community rejection, risk of weather conditions.

The drainage system on the Cihanjuang road in Cimahi City experiences flooding problems, especially during the rainy season. Flooding factors are caused by sedimentation, clogged garbage, and rainwater runoff from each settlement that cannot be accommodated. Based on these problems, research was carried out as an effort to overcome the problems that occurred. The method in this research uses a descriptive evaluative method, namely a research method that evaluates conditions objectively/as is. Primary data in this research was obtained by surveying the condition of the drainage channel at the location to determine the dimensions and existing conditions of the channel. Secondary data in this research was obtained via the NASA website in the form of rainfall data for the last 20 years. The rainfall calculation method used in this research is the Log Normal method with a rainfall intensity value of 74.316 mm with a return period of 2 years. This research uses EPA SWMM 5.2.3 computer software as a tool to carry out hydraulic analysis. The research results showed that there were four channel locations with existing drainage channel capacity that could not accommodate water runoff, namely J_10, J_17, J_21, J_48. So that Low Impact Development (LID) planning is carried out in each water catchment area to reduce water runoff. The results obtained show that the application of LID can overcome flooding problems. Apart from that, cost calculations were also carried out in making the four types of LID used, namely Bioretention-cell, Rain Garden, Permeable Pavement and Rain Barrel.
