Highway is part of the Science of Civil Engineering and always develops over time. In increasing the provision of land transportation, roads are important infrastructure that must be considered in development. The availability of adequate road infrastructure will have a positive impact on the development of community activities from the economic, political, social, cultural, defense and security aspects of the country.This research was intended to utilize Masuppu River Stones in Masanda Subdistrict as a mixture of AC-WC. The methodoIogy in this research is to conduct a series of tests for the characteristics of coarse, fine, and fiIIer aggregates, then design the composition of the Laston AC-WC mixture and the Marshall test to obtain the characteristics of the mixture and the MarshaII immersion test to obtain the immersion index (IP) / residuaI strength index (IKS) / durabiIity of the mixture with optimum asphaIt content. The results of research carried out at the Laboratory of Engineering and AspaI Functions of Engineering Department of Civil Engineering, Christian University of Indonesia, PauIus Makassar, show that the characteristics of the pavement material in the form of Masuppu River rock, Masanda District, meet the specifications as a road pavement coating material.

Pavement Construction

The implementation of road pavement construction so far has used materials imported from other places, and most of the road pavement constructions have been damaged before reaching the design life, so maintenance is carried out and even additional coating is given. This study aims to test the characteristics of the mixture of Laston Lapis Antara by utilizing Sungai Pucak aggregate according to laboratory tests. The research method is the Conventional Marshall test which is used to determine the KAO, then the manufacture of the KAO test object to obtain the Marshall Remaining Stability (SMS). The results showed that the characteristics of the aggregates originating from the Pucak River, Maros Regency for the Laston Lapis Antara mixture were in accordance with the General Specifications of Highways in 2018. The results of the characteristic test of the conventional Marshall mixture obtained that the values of stability, flow, VIM, VMA, and VFB all met the General Bina specifications. Marga in 2018. The Marshall Immersion test has complied with the 2018 General Highways specifications, where the value is 95.56%≥90%.

Floods And Droughts

Located in the Southeast Asia region, Indonesia has rainy and dry seasons. In the rainy and dry seasons that occur in Indonesia, often causes many problems in various business sectors and community activities, including floods and droughts. It is known that the disaster will have an impact on material and non-material losses. This study uses climate data and disaster data at the village level to determine the effect of rainfall on disasters. This study uses the instrumental variable method because the model has endogeneity problems. The study results concluded that increased rainfall had a positive impact on flood disasters with a coefficient of 0.003038. Simultaneously, rainfall also impacted drought with a coefficient of -0.000377.  Variables in the regression model that are formed can explain 1.74 percent of the flood disaster and 0.59 percent of the drought disaster. These results indicate that most of the other variables can influence flooding and drought. Through this research, it is known that rainfall for floods and droughts is quite significant. Therefore, government and community efforts are needed to anticipate similar disasters.

Pavement Construction

Several factors that can affect road damage are excessive traffic load, temperature (weather), water, and pavement construction that does not meet the technical requirements. The durability of an asphalt mixture is the resistance of the mixture to the effects of water, water vapor, and temperature. A mixture with a high durability value provides a good mix quality and long-term use. The purpose of this study was to determine the durability of the AC-BC mixture using Mount Baba stone. The general specifications of Bina Marga in 2018 are the reference in this study. By using the standard Marshall test method, the results obtained through the Marshall AC-BC mixture immersion test with a duration of immersion time of 0.5 hours, 12 hours, 24 hours, 36 hours, 48 hours, 60 hours with a durability value of 95.49% - 86.99%. The increase in immersion time causes a decrease in the durability of the mixture.

ABSTRACTAs part of their required curriculum, undergraduate students in the Civil Engineering Department at the University of Arkansas take a course that studies the materials commonly used in the construction of buildings, bridges, highways, and the like. This course is titled CVEG 2113 - Structural Materials. A focal point for this course is the examination of concrete, its production, engineering properties, and uses in structures.Since concrete can be delivered to a job site while still in a workable form, it is often necessary to perform a series of tests on the “fresh” material prior to its placement in a structure. Prior to the mid-1980's results from the field testing of concrete were often dubious. In an effort to improve the quality of testing, and thus the reliability and accuracy of the test data, organizations such as the American Concrete Institute (ACI) initiated programs to certify field testing technicians. With the students in CVEG 2113 already receiving instruction relative to testing, as well as having the opportunity to perform the applicable tests in the laboratory, it quickly became evident that ACI certification could, and should, be incorporated into the course syllabus. Being certified adds a tangible skill to a student's resume thus making the student more marketable for summer and long-term employment. The concrete industry benefits from an increased pool of highly qualified engineers. The Department of Civil Engineering benefits from an enhanced reputation from the perspective of both the students and industry.

Sepuluh November Institute of Technology (ITS) encourages the ECO Campus program. The program enables ITS to systematically identify, evaluate, manage and improve their environmental performance and practices. One of the program issue is energy saving in building. The energy saving effect of an air-conditioning system retrofit project is analyzed by Energy Conservation Opportunities (ECOs) Method. These ECOs are assessed in terms of their costs and benefits, and an economic comparison to rank the various refrigerants. Finally, an Action Plan is created where certain ECOs are selected for implementation. Civil Engineering Department has a responsibility to design infrastructure and green building concept planning. This department also has the largest energy consumption in this faculty comparing the other department. The energy consumption on this Department is 60829 kWh/month. The value of IKE is 13.39 per month with the largest electrical energy consumption in air-conditioning system is 57% from total consumption. The energy used of air-conditioning sytem is 523.692 kWh. The energy saving opportunities by CFC retrofitting with hydrocarbon can save its power consumption about 20%. It also saving cost and reducing the electricity bill of 1643871.838 IDR/month. The payback period of investment costs of retrofit R-22 to Hydrocarbonis about 13 month.
