The Seminar of Civil Engineering and Building Environment Held by Faculty of Engineering University of Bengkulu with The Theme “Green Construction”
This National Seminar is an annual activity held by the Civil Engineering Study Program, Faculty of Engineering, University of Bengkulu. The opening speech was delivered by the Head of Civil Engineering Study Program, Mukhlis Islam, S.T.,M.T. The seminar raised the main topic of Green Construction and invited the experts to deliver the topics. The speeches at this National Seminar were presented by Prof. Dr. Ir. Abdul Hakam, M.T. (Andalas University, Padang, West Sumatra), Dr. Kusnindar Abd Chauf, S.T., M.T. (Tadulako University, Palu, Central Sulawesi), Ahmad Yudi, S.T., M.T. (Institute of Technology Sumatra, Lampung), Lindung Zalbuin Mase, S.T,. M.Eng., Ph.D. (University of Bengkulu), and Dr. Gusta Gunawan S.T., M.T. (University of Bengkulu). At this year's National Seminar, there were 20 papers to be presented, as well as participants who came from various universities and institutions. Then, the agenda was followed by the opening speech from the Dean of the Faculty of Engineering, University of Bengkulu, Faisal Hadi, S.T., M.T. He conveyed a good appreciation of this event and said that the main topic has been raised in this event is very necessary to be conveyed and important for many people, considering the efficiency of green construction will have a good impact in various facets and for long term.
The Seminar was conducted on Wednesday, October 14, 2020 through Zoom Meeting, the first topic was presented by Prof. Abdul Hakam. The topic was focused on Damage of Buildings Due to Liquefaction. Liquefaction is a soil condition that changes from solid to liquid, and causes a sudden and significant land subsidence. In it’s submission the damage of buildings and public facilities is very potentially and dangerous caused by Liquefaction of land, it is important to pay attention and take into account the potential of such Liquefaction with good planning to avoid or prevent damage and losses that will occur in the future. In short, we can achieve efficiency in energy used and resource consumption when we pay attention to good planning against Liquefaction.
Then Dr. Kusnindar Abd Chauf provided the topic by focusing on the uses of wood materials. Wood materials have a much better effectiveness and efficiency, and are environmentally friendly, ranging from planning of the construction to building operations. It should be noted that the use of wood is not obtained from the forest, so as not to interfere with the sustainability of the current forest. Because the wood used is non-forest wood. The method is used Laminate method between two wood materials, and the result is very possible to be used as a building construction material and public facilities as well as produce efficient and environmentally friendly construction.
Further, presenters were still discussing about construction in term of material used, the topic was Zeolite material delivered by Mr. Ahmad Yudi, S.T., M.T. Zeolite material has two types which are natural and synthetic zeolite. In this case, the talk was more emphasized in the use of natural zeolite materials. In the testing carried out, it was expected that the use of natural zeolite materials can be optimized as a substitute for cement. Thus the construction material will be friendlier to the environment because it comes from nature.
Raising the same topic as the previous presenters, Lindung Zalbuin Mase, S.T., M.Eng., Ph.D. delivered about the Liquefaction from a different side, the effect of Liquefaction caused by Earthquake. Through the paper of the results by research conducted that has been produced, a Local Spectra Acceleration Design Map of Bengkulu Region, considered the rate of earthquakes in Bengkulu area is quite high. Local Spectra Acceleration Design produced for Bengkulu area will be very effective for use in civil engineering building design, not only in Bengkulu area but the influence of earthquakes that can cause Liquefaction and damage to buildings directly can certainly occur in any regions. Therefore, good construction needs to be done with that effect in order to achieve long-term efficient construction with Liquefaction potential in consideration.
The last discussion was delivered by Dr. Gusta Gunawan with the topic in terms of Water Management. According to his speech, Indonesia has good water availability, especially Sumatra. For Bengkulu itself 96.53% of water is wasted into the sea, thus meaning that the need for water used is still very little. In spite of that fact, Bengkulu is also a flood prone area. Therefore, it has become a challenge that must be achieved in solving the flood problem. The flood problem can be caused by two sources, which is Flood upstream and Rain. Managing water resources in a good way could prevent flooding that can cause damage and losses economically and in other facets. This can be done starting from the surrounding environment, as well as physically and non-physically.
