Arus Jenuh Dan Panjang Antrian Pada Simpang Bersinyal Angkatan 66 Kota Palembang

The high saturation flow, long queues, and long delays at the signalized intersection are the factors causing traffic congestion at the intersection. This study discussed saturation flow analysis and long queues at the Angkatan 66 signalized intersection in Palembang City. The intersection legs at this intersection, namely Jln. Sukamto toward Jln. Basuki Rakhmat, Jln. Amphibi toward Jln. Angkatan 66, have high saturation flows and long queues, so that the intersection needs to be improved. There are 3 improvement alternatives, including the change in cycle time period, the change in intersection geometric, and the construction of flyover. Of the three alternatives, only the construction of fly over construction can reduce significantly the queue lengths

Karakteristik Transportasi Kabupaten Banyuasin Sebagai Daerah Penyangga Kota Palembang

Banyuasin Regency is a buffer zone of Palembang. Many of Banyuasin residents work in Palembang, and vice versa, causing a lot of travel between these two regions. The objective of this research was to study the characteristics of the transport, trip generation and attraction, as well as the traveling route in these two areas. Origin and destination interview surveys as well as the calculation of the traffic volume were conducted in this study, followed by the calculation of interaction and connectivity. These studies suggest that the purpose of travel is predominantly for work (30.1%) with a distance of more than 20 km. Generated trips consist of 178 private vehicles, public transport of 270 people, and 99 goods transport vehicles. While the attracted trips consist of 156 private vehicles, public transport of 298, and 116 goods transport vehicles. Only 12 districts have overland routes to Palembang while 7 others do not have a land route to Palembang

Effect of voids in kaolin stabilised by ground granulated blast furnaces slag mixtures

Kaolin is known as problematic soil which has a low strength that needs to improve before construction. Chemical stabilization with cement is used widely to stabilize different clay types; however, using it comes with disadvantages associated with carbon dioxide emission and sustainability issues. As an alternative to cement, Ground Granulated Furnaces Blast Slag (GGBS) has been applied to stabilise kaolin. The increment in the strength is due to the formation of new products that fill the soil voids. The formation of those new products is verified using Field Emission Scanning Electron Microscopy (FESEM). However, the changes in pore space cannot be quantified using FESEM. Thus, this study uses Image J to calculate voids area detected by (FESEM) for different kaolin-GGBS mixtures with different content of GGBS cured for different curing period. The book-like structure for the raw kaolin have changed slightly when mixed with GGBS. This is due to the formation of hydrate gels as a result of the pozzolanic reaction. The results from image J indicates that the void decreases as the content of GGBS increases as well as the curing period
