Scheduling is a problem that is often encountered in everyday life, including in manufacturing companies. One type of scheduling problem that is commonly found in the industrial world especially the textile industry is the ...
Many companies in Indonesia already have completed sustainability reporting (SR) in their corporate reporting eventhough the regulation has not required public companies to disclose Integrated Reporting (IR) in their report. ...
Lim, Aswin; Atmaja, Petra Cahaya; Rustiani, Siska(Elsevier, 2020)
This article presents an innovative method of bio-mediated soil improvement for increasing the shear strength of loose sand. The improvement is realized by mixing the loose sand with the inoculum of Rhizopus oligosporus, ...
This paper presents a novel strut-free earth retaining wall system for excavation in soft clay, referred to as the rigid and
fixed diaphragm (RFD) wall retaining system. The RFD system is comprised of four main ...
Lim, Aswin; Chang-Yu, Ou(Southeast Asian Geotechnical Society, 2020)
The paper presents the performance of two deep excavation Case-histories and their three-dimensional finite element
analyses. Case 1 describes the application of cross walls and buttress walls in controlling the diaphragm ...
The U-shape wall is an innovative application of a composite buttress-cross wall to reduce excessive movements induced by excavation. The performance and mechanism of the U-shape wall in controlling the deformations were ...
Pei-Yan, Lin; Lim, Aswin; Shu Ken, Ho; S. Ping, Ho(Taylor & Francis, 2018)
The objective of this study is to propose and evaluate a novel composite earth retaining structure method to
be applied in urban excavations in terms of construction safety, cost, and duration. The novel composite
structure ...
The objective of this study is to examine the stress state of soils during deep excavation, in relation to the determination of appropriate soil parameters for deformation analysis of a deep excavation case using
the ...
Three-dimension finite element analyses of deep excavations with buttress walls were performed to evaluate
the effect of buttress wall shapes on limiting movements induced by deep excavation. Results showed that a combination ...
Salura, Purnama; Clarissa, Stephanie; Lake, Reginaldo Christophori(University of Malaya, 2020)
As a reaction to the monotonous expression of typical International Style architecture, vernacular architecture is often applied to the design of modern buildings. Unfortunately, most of these applications are limited to ...
Salura, Purnama; Clarissa, Stephanie; Lake, Reginaldo Christophori(University of Malaya, 2020)
The architectural discourse in Indonesia generally focuses on traditional architecture that represents specific regional icons, the synthesis of traditional architecture with European-style architecture, and modern ...
The pattern of water use operation is important to ensure the continuity of water supply system of a reservoir. This pattern, which is usually called power rule curve in a hydropower system, should be
optimally obtained, ...
In this study, a two-dimensional cell-centred finite volume scheme is used to simulate dis- continuity in shallow water flows. Instead of using a Riemann solver, an artificial viscos- ity technique is developed to minimise ...
Ginting, Bobby Minola; Mundani, Ralf-Peter(American Society of Civil Engineers, 2019)
In this paper, a shared-memory parallel simulation of flood modeling is presented. The model used has second-order spatial and temporal accuracy, where the Monotonic Upwind Scheme for Conservation Laws (MUSCL) method is ...
In this paper, the Reynolds-averaged Navier Stokes equations supplemented by the algebraic stress model are solved using the central-upwind scheme for simulating 2D turbulent shallow flows. The model is of spatially and ...
Ginting, Bobby Minola; Ginting, Herli(American Society of Civil Engineers, 2019)
In this paper, a hybrid artificial viscosity–central-upwind (AV-CU) scheme is proposed for simulating recirculating turbulent shallow water flows by combining the artificial viscosity (AV) technique with the central-upwind ...
Ginting, Bobby Minola; Ginting, Herli(Elsevier, 2020)
This study highlights the solution of the 2D non-hydrostatic shallow water equations using an artificial viscosity (AV) technique. The model recently proposed by the first author in Ginting (2017) is extended in this paper ...
The launching of the ASEAN Economic Community (AEC) in 2015 opened a regional market of 600 million people. The formation of AEC facilitates the opportunities for entrepreneurs to offer goods and services in the
market. ...
Most of the quantitative studies on price transmission of agricultural products deal with estimating and testing elasticity as well as detecting the presence of asymmetries in the transmission mechanism. It has been argued ...
Widyarini, Maria; Pawitan, Gandhi(Global Science and Technology Forum, 2011)
In this paper, a VAR model is developed to study the effect of exchange rate fluctuation on rice imports in Indonesia.
While the Basic Theory states that the exchange rate depreciation has a positive impact on economic ...
O’Dell, Luke A.; Gunawidjaja, Philips N.; Holland, Mark A.; Mountjoy, Gavin; Pickup, Dave M.; Newport, Robert J.; Smith, Mark E.(Elsevier, 2008)
The HfO2–SiO2 system is attracting interest as a possible new dielectric material in semiconductor devices. Knowledge of the location of hafnium within the silica network and the effect hafnium has on the structure will ...
