Building Materials Composition Influence to Sound Transmission Loss (STL) Reduction Erni Setyowati1,a, Anggana Fitri Sadwikasari2,b 1Building Science Laboratory, Engineering Faculty, UNDIP, Semarang, Indonesia 2Islamic University of Indonesia (UII), Yogyakarta, Indonesia aernisyahdu@gmail.com, banggana@gmail.com Keywords: Airport noise, building material composition, STL reduction.
The development of the airport always causes the noise impact to the surrounding environment.1 Housing close to the airport will be annoyed by the aircraft noise, especially if the building is not added by absorber building materials.
The decrease of the noise level found out from the research is caused by the value of Sound Transmission Loss (STL) of the building materials composition.
In some journals that I wrote that the building models are not assumed to be a single model.

The materials transportation system with storage bin is widely used in mines, power plants, material yards, and etc.
Introduction In some materials transportation system, storage bins are often set.
The block diagrams of the materials transportation system with storage bin.
(1)When links ahead of bin 1 are in failure, links behind bin 2 can continue transporting materials of bin, The maximum value of materials of bin is designed bin capacity Q tons.
