Authors: Kristianto L , Rarasati A D , Sjah J 
Published: August 2021

Abstract
Determining building design and type of material is very important before initiating a construction project because structural design changes can impact the project’s cost and duration. This study will discuss the impacts of such changes in building design, both on structure and on cost and duration. It will focus on a case study of a showroom office building that intends to change the design of its roof from concrete to steel frames. The research will be carried out using the Finite Element Method numerical modeling, as well as cost and duration analysis. The use of steel frame may shorten the construction duration while the use of concrete roof may lower the cost.

Abstract

As one of dam priority in Indonesia, Cipanundaan dam faced severe problem related to the sedimentation. The sedimentation in Cipanundaan derived from both soil erosion and landslide (earth slide and earth flow) along the river. Based on analysis, total potential sediment reached until 137,819 m3, which is shortened the dam lifespan only for 10 years. This research is conducted the effectivity of application of underwater dam in order to maintain intake system. Three underwater dams are constructed for controlling 8 mm/year of sedimentation from both erosion and translational landslide. The numerical modelling used ANSEDIM program to develop surface sediment elevation in reservoir. The result showed the infrastructure is succesfully suspending sediment enter the system, thus, the dam has a longer lifetime. The research revealed that application of three underwater dams will reduce 2.5 times of sediment volume, increase up to 6 times of effective volume and extend the dam’s lifetime until 250% from existing condition. This outcome will be helpful to planner, engineers and managers for better managing of reservoir sedimentation and water resources.

Authors: Susilawati C L , Hartono  
Published: August 2021

Abstract

Mbay City is a lowland city flanked by rows of mountains and agricultural rice fields. This barren mountain range causes rainwater mostly flow towards the urban lowlands, as flood. The city of Mbay which consists of 3 different regional groups, namely mountains-lowlands-rice fields, encourages a sustainable water supply and management with an eco-hydraulic concept. First, it is necessary to understand the terms eco-hydraulics, sustainable water management and sustainable water supply as well. Furthermore, we can find the right innovation to handle the three distinctive areas of the different Mbay cities. Mountain areas need water conservation that applies ecological concepts, while urban plains need hydraulic handling to drain flood water from the city, and rice fields also need ecological handling so that rice fields are protected from overflowing sea water when high tide occurs. Finally, it can be said that the integrated handling of ecology and hydraulics concepts has made the city of Mbay able to manage and supply water in a sustainable manner.

Abstract
Economic movements in Indonesia and the logistics and distribution systems that accompany them are highly dependent on road transportation modes. On the other hand, the islands of Sumatra and Java are the centers of concentration for the Indonesian economy where the number of people inhabiting the two islands reaches 80% of the total population of Indonesia. In order to accelerate development and increase the economic integration of Java and Sumatra, it is necessary to build the Sunda Strait Bridge. The main bridge considered incudes the long span suspension bridge. At present, the planning and construction of the long bridge including suspension bridge was greatly affected by the failure of the Taccoma Narrow Bridge on 7 November 1944. Due to the wind load, the bridge structure shook until it finally collapsed. Although the cause of the collapse was not immediately known, it is currently concluded that it was caused by a single degree of freedom torsional flutter caused by self-excited wind load. This phenomenon is classified as an aerodynamic phenomenon on long span bridges. The flutter analysis performed on the Sunda Strait Suspension Bridge using the Direct Flutter Analysis method will be presented in this paper.

Abstract
The hydraulic jump is a process is to reduce most of the energy that occurs in spillway. It can also raises the water level in the lower reaches. A very large energy flow that must be reduced so as not to endanger the end of the dam’s overflow channel. The dissipation structure, such as stilling basin at the end of the spillway, plays a role in reducing kinetic energy flow before the flow enters the river. This paper aims to analyse the effect of the baffle block along with the layout of the stilling bed. The experiment was comparing the stilling basin without and with a baffle block, where hydraulic jump intently occurs with variation of flow rate from Q50 to QPMF. This research results that stilling basin with baffle block with a bucket angle of 23.33°has the most effective variation among the others compared to Lj and Hj values. Lj/H1 and H2/H1 has linear relationship with Froude Number (Fr), which is the higher discharge rate, the higher Lj/H1, H2/H1 and Fr value they obtain.

Authors: Subroto Annisa Azzahrah , Zuraida Rida 
Published: August 2021

Abstract
The increasing mobility drives demand for fast, reliable, and safe public transportation. Nowadays, the citizen of the main city in Indonesia relies on app-based transportation to fulfill these needs, especially the motorbike taxi services. Many factors affect the convenience and safety of the passenger, especially a driver’s driving behavior. This research aims to measure a motorbike taxi driver driving behavior level using a Manchester Driving Behavior Questionnaire (MDBQ). Furthermore, the correlation between emotional intelligence (X1), the need for self-recovery (X2), and work motivation (X3) variables with driving behavior (Y) was measured. Using a set of questionnaires, the 200 app-based motorbike taxi drivers’ opinions on those variables were collected. The participants were drivers who operate in the Indonesian capital city and its four adjacent cities. To see the correlation of the variables, a Binary logistic regression method was applied. One way ANOVA was also utilized to find out whether the age, driver’s income, and driving duration differentiate the level of Y, X1, X2, and X3. The result showed that X1 had a negative influence on the Y, while X2 and X3 had a positive influence. The correlation can be explained by the equation Y=- 7,491 + 0,067X1 + 1,388X2 + 0,577X3
. One way ANOVA results showed that the emotional intelligence level statistically different among the age class (p = 0.095), the work motivation level statistically different among drivers with different driving duration per day (p= 0.035). This research provides a new perspective that driving behavior is influenced by those variables. The implication, to manage or to correct the driving behavior of drivers, the app-based transportation company service could set some regulations related to this matter. The company may consider limiting the driving duration and give rewards to the drivers who able to manage their driving duration and their driving behavior.
