Mass Movement Using the Bingham Fluid Model and the Voellmy Fluid Friction Model. (Case Study of Songan Village, Kintamani, Bali)
Indonesia is located on the Ring of Fire of Pacific Rims. This condition makes Indonesia at risk of geological disaster. One possible occurrence is mudflow. On February 10, 2017, mudflow occurred in Songan Village, Kintamani, Bali, which destroyed 6 houses and killed 13 people. Further study is needed to predict this type of occurrence. This study aims to identify the characteristics of the soil at the deposition area of mudflow and verify the duration, flow depth, and velocity of mudflow. To achieve these objectives, a rheological study is conducted using the Bingham fluid model and the Voellmy fluid friction model in Flo-2D and Rapid Mass Movement Simulation (RAMMS), respectively; the simulation results of both models are compared. From the results of the program simulations, RAMMS’ results are found to exhibit a higher velocity of mass movements than that of Flo-2D’s results. From the results of this analysis, small viscosity is observed to result in small flow depth and high velocity of mass movements. Keywords—Mudflow, Bingham, Voellmy, Flo-2D, RAMMS.
Flow Velocity Distribution Analysis On Free Intake Structure And Its Influence To Intake Capacity
As maritime state, most of Indonesian reside in coastal areas or estuaries, leading sanitation and water supply a major concern of the people. The use of groundwater with considerably limited amount is more limited due to seawater intrusions. On the other side, surplus of freshwater from upstream is very abundant near the estuaries. However, morphological condition of river downstream or in estuaries with huge dimension and depth causes expensive cost in order to utilize freshwater in estuaries. One of the solutions to utilize water downstream or near estuaries as raw water for clean water is to build free intakes around river estuaries. However, as the utilizing proceeding, it is found a problem that intake capacity is far below their design capacity. The research is an experimental research conducted in the laboratory which aimed to investigate the relationship of flow velocity distribution on no free intake and with free intake condition and its influence to the capacity of free intake structures. The result shows that either on no free intake and with free intake condition minimum velocity occurs around channel bed and increasing upright and decreasing again when approaching surface of the channel. The positioning of intake pipe is highly influencing intake capacity. Maximum condition is achieved when intake pipe is positioned on channel bed and near channel surface while minimum condition is achieved when pipe is around middle part of the channel. Keywords—Free intake: velocity distribution: intake capacity.
Modelling Subgrade Modulus Using Deflection of Falling Weight Deflectometer
The value of sub grade modulus is required for pavement management system (PMS), design and evaluation of a pavement system. In the overlay thickness design the first thing should be carried out is to predict the modulus of existing sub grade. While in the PMS this value is used for reference in segmenting of tested road links. There are several methods available to calculate subgrade modulus based on the Falling Weight Deflectometer (FWD) deflections. Generally, calculation of sub grade modulus from FWD deflections need information of total pavement thickness above sub grade level. This information is quite difficult because it needs testing using equipment called Ground Penetrating Radar (GPR). This equipment is relatively expensive and the main thing it needs the skilled engineers to interpret the GPR results. This research aims to find the correlation between FWD deflection to that of the modulus of existing subgrade, so that the calculation of sub grade modulus based on FWD deflection does not need the information of total pavement thickness anymore. The research starts by simulating pavement under standard traffic load (4200 kg) and then calculate the surface deflection on the points which are located as exactly same as the FWD geophone are. The simulated pavement model consists of 3 layers i.e. surface layer of flexible, base layer of granular, and sub grade. A computer program called KenPave is used for this simulation. This program is able to calculate the deflection, stress, and strain in any location of pavement system by inputting layer thicknesses, modulus of each layer as well as Poisson’s ratio. There are 3800 variations of simulated pavement system which vary modulus and thickness of each layer. After that it is carried out modeling of subgrade modulus and the value of deflection at the 900 mm offset (D 900). It is then obtained a logarithmic model that correlates the value of sub grade modulus and the deflection at 900 mm offset. The correlation factor is quite good (r21, A M S Sufanir = 87.5%). The final step of the research is to test this model using field data of FWD and the results are compared to back calculation results using FWDArea and Elmod programs. It is then found that when the results are plotted each other, they all fall around line of equality. It means that the sub grade modulus obtained from the model is not significantly different to that of back calculation result. In the other words, the logarithmic model between sub grade modulus and FWD deflection of 900 mm offset is acceptable. This model could help pavement engineers for predicting the modulus of existing sub grade very fast.
Designing emergency support functions for functional exercise. A case study in field of firefighting in Haiphong, Vietnam
Hazard and risk of accidents exist all over the world as part of human life. From developed countries as United State of America and Japan to developing countries as Indonesia and Vietnam; governments, organizations and communities share their specific responsibility in emergency management depending on history of disasters, policy structures and cultures. Emergency training and exercise are important programs to enhance the resilience of society. The Deming cycle known as Plan-Do-Check-Act (PDCA) cycle is effective instrument for continuous improvement of management. Therefore, doing preparedness exercises play a significant role of emergency plan improvement. Our research focuses on how to evaluate adequacy of emergency plans and resources of organizations through table-top and functional exercises. In particular, we research on designing effective exercises for emergency relief organizations. Through reviewing different styles of functional exercise, we introduce and verify idea of Kitakyushu functional exercise (KFEX) in Vietnam. KEFX is a new style of doing functional exercise by providing methods of exercise design, data observation and results analysis. It provides possibility to evaluate quantitatively trainee performances through timing each task of participants and utilizing a cloud support-software tool for functional exercise. To apply KEFX in context of Vietnam, we designed a functional exercise in considering the structure of emergency relief organizations. Haiphong Police of fire prevention and fighting (Haiphong PoFF) has been defined as a case study to expand KFEX idea. Because emergency support functions (ESFs) are foundation to design exercise, we proposed and checked ESFs for functional exercise in Haiphong city, Vietnam. In March 2017, we implemented the demonstration of function exercise as a feasible study for applying idea of KFEX. Participants in the demonstration include Controller group, Evaluator group and Player group, those belonged to Haiphong PoFF. Task processing network and time consumption for each task were recorded by software support tool. In this paper, we will explain process of exercise design and share results after the demonstration in Haiphong PoFF.

Sustainable House For Low-Income Community In Indonesia
Efforts to eliminate slum areas in urban areas are a global program undertaken in many developed and developing countries through the provision of housing for Low Income Communities (MBR). In Indonesia, MBR house prices are limited to a maximum of IDR 200 million per unit, so developers effort to find ways to reduce costs to produce houses that meet the standards. This article reviews the house design for MBR which is not only cheap but qualifies for sustainability. The literature review resulted that this design should be able to accommodate a floor space of 10-13 m2 per capita as the optimum value of human social space. In addition, the results of the analysis require developers to provide a minimum green roof of 10% of the flat roof area, in order to lower the environmental temperature that affects the decrease of human aggressiveness and increase social attachment. Preferred materials were materials that were easy to obtain and cheap and certainly feasible to be building materials. Natural lighting during the day could be sunlight from closed glass windows and LED lights for night and enclosed spaces. Together with a number of other specifications, this article provided a concept of sustainable houses for MBR in urban environments that developers could use to reduce costs while ensuring sustainability. This concept refines the old concept that has been used by the government. The government needs to change standards and implement regulations that prohibit adding space or changing the shape of buildings. House prices with sustainable prototypes are slightly more expensive, but this is a compensation for unnecessary renovation while occupying the house

Value-based Design Decision on Building System Selection
This paper presents a decision model for technical solution options on building system selection. There are many studies on design decision making using multicriteria, such as in assessment of exterior building wall system; selection of steel structure; structural alternatives of prefabricated concrete and metal clad; and roof system selection. The characteristic of value criteria has not been widely used to previous research. Existing models that are commonly accepted are optimization-based models, for example aggregation methods, but these are not able to solve the problem of value criteria on design decision. The model is based on a satisficing function/cost preferences. It is multi-attribute, and the environment is in a Value Management (VM) process. Since “value” is the main single objectives for the decision model of VM, the attributes for this decision model therefore is function and cost. This also provides the method to construct the Life Cycle Cost (LCC) analysis for the cost attributes and the Function Analysis System Technique (FAST) for the function attributes. This research applies the satisficing game method where function and cost of solution techniques for a building system is formulated and the reduction of the technical solutions based on function/cost preferences can be made. Therefore solving the problem on computerizing the creativity of human/decision participant helps to elaborate on every possibility of the technical solutions and reduce them before choosing the best solution

Fire Evacuation Plan Based on Availability of Time in a Conservation Area
The preservation of buildings in a municipal conservation area is not sufficiently supported by the regulations imposed on the building when it is restored or converted. The immediate area surrounding the conservation building remains a freely constructed area. The existence of the new buildings can unwittingly threaten the continuity of the conserved buildings. Other forms of threat to the preservation of cultural heritage buildings other than demolition are fire hazards that may originate from buildings around preservation objects that may endanger the continuity of conserved buildings. When access to fire-fighting and human-saving assistance is only by dismantling old building, even conservancy building have to yield. Consideration to the classification of the conservation building, its location in the downtown area, the situation and the density of the surrounding area, adjacent building function and the architectural style of the conservation building is not enough. The readiness of new buildings in terms of response to the fire ignition, the preparedness of water facilities for fire suppression within 45 minutes, occupants rescue, accessibility of assistance, becomes a matter of concern when the building permit is issued. The prediction of time egress for occupants by utilizing IES (Integrated Environmental Solutions) technology, applied to a design as an example can be used as the basis for designing rescue paths, determining the assembly points as a save destination, early in the design process. The results of this time calculation can also be used to prepare the postoccupation fire management in the future. The right action based on the available time to save the conservation area's inhabitants and its surroundings, will also save the conservation building
Perception Study on the Facilities for Walking. (Case Study of Bandarlampung, Indonesia)
Urban transport is single-handedly responsible for emitting approximately around one fourth of global carbon dioxide in the atmosphere. Therefore by improving the development of non-motorized transport modes, the emission could be substantially decreased. The non-motorized transport modes are often referred as low carbon transport mode as they emit zero to low level of carbon. Cycling and walking are the most popular form of low carbon transport with the later often receives less attention in conventional urban development. On previous studies, authors identified key-elements of Pedestrian Profile, Pedestrian Activity, and Pedestrian Environment which are being introduced by authors as its abbreviation, PL.AC.E.

We make onlinesystem gps tracker which utilizestechnology of theGlobalPositioning System available today, can provide precise and accurate information, the public is more in make it easy and get better service. GPS is a satellitebased navigation system developed by the US Department of Defense (US Department of Defense DoD) in early 1970. GPS was originally developed for military purposes in the United States, then in the 1980s opened GPS access also for civilian purposes so that the current GPS can be used both for military and civilian users. At that time in 1973 there are 31 GPS satellites that orbit the Earth (source: http://www.gps.gov,Official US Government information about the Global Positioning System andrelated topics). These satellites transmit the coordinates to a receiver on the ground. The GPS system can monitor and determine the location of an object that wants to be known almost anywhere in the surface of the earth. GPS will capture the satellite signal from the surface of the earth to be translated into a coordinate point. The coordinates of the point we can integrate digital maps to findthe position of an object.
