Doctor of Civil Engineering Study Program, Faculty of Engineering (FT) Untar Open Dissertation Defense inaugurated Lonny Siahaya as a Doctor of Civil Engineering, Wednesday (2/8) at Untar auditorium.
Lonny Siahaya managed to defend her dissertation which titled “Development of Road Construction Hardening with Bina Marga Method Utilizing Local Materials of Sarmi Regency, Papua Province”.
Her dissertation focuses on the development of road structure in Papua using Lime Base Cement (LBC) technique. The structure of roads in Papua consists of a mix of limestone and cement.
Lonny said her dissertation started from the condition of roads near her house, which often worsen in a short amount of time, even after reconstruction.
According to her, Papua produces limestone which has durability twice of Indonesian standard. Therefore, theoretically, roads in Papua should be able to sustain longer.
Regarding this, Lonny stated several recommendations to the problem. Papua, especially Sarmi Regency, needs to have an adequate laboratory. This is needed to conduct extended research and test of structures and materials before executing construction.
Therefore, there will be cost reduction and an increase in effectiveness of construction. Lonny said that currently, the nearest laboratory is located in Jayapura, around 300 kilometers from Sarmi.
“I hope this research will be able to be implemented in Papua for the betterment of Papuan roads and general welfare of Papuans, particularly those in Sarmi,” Lonny said.
This statement was supported by Lead Promoter Prof. Dr. Ir. Bambang Sugeng, DEA. Prof. Bambang in his closing statement said that the knowledge owned by Lonny could be beneficial for Papua, based on the natural resources available in Papua.
Lonny Siahaya is the 70th graduate of Doctor of Civil Engineering Study Program, Faculty of Engineering Untar.
Lonny graduated with a very satisfactory predicate in the dissertation defence which was led by Rector of Untar Prof. Dr. Ir. Agustinus Purna Irawan, M.T., M.M., I.P.U., AE, and as examiners Dr. Ir.
