<![CDATA[This paper presents a study of Rapid Visual Screening (RVS) using FEMA 154 and applied in Indonesia based on SNI 1726. RVS is a method to asses potential earthquake hazard of a building based on visual observation (“sidewalk surveyâ€) of the exterior and interior building if possible, and a Data Collection Form. This study is intended to see how important the RVS of the FEMA 154 can be implemented in Indonesia with a case study at Yogyakarta. The buildings that reviewed were assumed to have the same parameters as mention in FEMA 154 and compatible with SNI 1726 (Indonesian earthquake map). The results from field survey were compared to the numerical analysis. From the case study, it was found that the administration building of ATK Academy, the dormitory building of Ministry of Internal Affairs, the office building of Department of Agriculture, and the educational building of Health Polytechnics have a score more than 2, and the buildings are also declared safe according to SNI 1726.]]>

<![CDATA[Indonesia has high a demand level of wheat flour for both the industrial and households sectors, such as bread industry. Wheat flour is the dominant composition of bread, however it is the source of gluten which may promote celiac disease (CD). The lifetime obedience to the gluten-free diet is the only treatment for this disease. The finding of a new material in order to obtain gluten-free product is an important topic. Furthermore, Indonesia is a tropical region that is rich in natural resources, such as cassava (Manihot esculenta) and Sorghum (Sorghum-bicolor (L) Moech). Fermentation was used to improve nutritional content of sorghum flour and cassava flour, resulting modified cassava flour (mocaf) and modified sorghum flour (mosof), respectively. A strategy for utilization of cassava in production of mocaf was demonstrated. Mocaf flour can be produced by fermentation use L. plantarum, S. cereviseae, and R. oryzae that are cheap and non pathogenic to increase the levels of protein and decrease the levels of cyanide acid in the mocaf flour. This work has also shown that lactid acid is produced as by-product during the fermentation.]]>

<![CDATA[The study focuses on the utilization of pineapple leaves fiber as a raw material for the production of geotextiles. The fiber yarns were weaved based on required size of sample issued by the Philippines Textile Research Institute (PTRI) of the Department of Science and Technology (DOST). The Zwick/Roell Tensile Strength Tester Z050 (CRE) with 50 KN full scale load was used with the Wide-Width Strip Method in order to get the average tensile strength of the specimens each for both pineapple and abaca geotextile samples. The resulting average tensile strength and average nominal thickness for pineapple leaves geo-textile, when compared to abaca geo-textile has higher tensile force for a thinner sample of pineapple leaf geo-textile.]]>

<![CDATA[This research presents a method of detecting critical situation for longitudinal vehicle dynamics. First, the dynamical system is modeled that consists of longitudinal tire force and longitudinal aerodynamic drag force. The longitudinal tire force is well known to be highly nonlinear. However, one can classify it in three types of operation : normal zone, critical zone and skidding zone. Normal zone represents the linear part of longitudinal tire force while in the critical zone, the vehicle does no longer correspond to the linear system. The difference between the nonlinear force and its linear model is considered as a fault that has to be detected. The aim of this project is to detect that fault. As the system depends on the speed of the vehicle, a Linear Parameter Varying (LPV) dynamical system is considered and an LPV fault detection approach is handled. An extension of the parity-space approach for LPV systems is applied to detect the fault on the vehicle. In order to accommodate the existence of the faults, the H∞ robust control system has been designed. Afterward, it is found that the controller can accommodate the faults. This research have been also implemented on a 1/5th scale vehicle by the simulation.]]>

<![CDATA[Yogyakarta is always flooded by tourists both domestic and foreign. Malioboro street corridor, from Tugu Station to Keraton Yogyakarta, is one of the most visited tourism area in Yogyakarta. However, Ahmad Dahlan’s corridor as one of the important access that link the tourism area reduces its identity by the declining quality of its outdoor space. The analysis techniques are spatial behavior analysis, character appraisal and walkthrough analysis. The study found that declining quality of the outdoor space, such as lack of identity and sustainable street furniture that supports the activities of visitors in tourism areas. In this case, the linkage design, as a transition must be able to show the identity of the corridor to connect the surrounding area visually and spatially]]>

<![CDATA[The market share of freight transport which is dominated by road transport and accompanied by unbalanced of infrastructure’s growth and freight demand has created various negative impacts on existing transportation system. The shift of freight transport from road to rail and sea is expected to reduce those impacts. Research on the behavior of freight mode choice and the extent to which the user is willing to trade off the attribute change needs to be done so that the amount of modal shift will be known. The main objective of the study was to produce a model of mode choice based on preference surveys among forwarders, as well as to provide inputs for policy improvement and or improvement of freight transportation services. One of the surveys to be conducted is the revealed preference (RP) survey. The important stage before the RP survey is to conduct a preliminary survey. This stage aims to determine the important trends related to the choice of modes by the forwarder and test the response rate of respondents. The survey is also useful for assessing the credibility of the data instrument, identifying potential errors in the data instrument, and determining non-conformities in survey management before the actual survey. Data collection was done by sending questionnaires. The structure of the questionnaire consists of questions about characteristics of : shipment, travel, and modes. The results of survey showed relatively low response rate because it was only 8 respondents who were willing to answer the questionnaire. This indicates that the questionnaire needs to be combined with other methods, such as: face to face interviews and or focus groups. The results of the preliminary survey show that the main factors for the choice of existing modes are: shipment costs, loss/damage, and time travel. The implementation of the next stage survey should consider that each company has more than one shipping commodity so it is necessary to group questions and analysis based on each commodity.]]>

<![CDATA[Bangkalan district has the potential unallocated aggregate to be applicated as a concrete mixture in the form of fine aggregates (sand) and coarse aggregates (gravel). In fact, Bangkalan aggregate implies excellent structure, so this material is rarely used as a mixture of concrete because with its fine structure the quality of the concrete produced will be less good. To maximize the use of aggregates from Bangkalan, a concrete mixture design analysis is conducted. The study is based on a test of the physical properties which are classified into five variations. Variation one implies a combination of 5/10 and 10/20 use of gravel and sand from Bangkalan when modification two only change the subject of Bangkalan sand to Lumajang sand with the same proportion. Variation three is treated a combination two with a given 0.3% of additive type D. The variation is increased to be added more additive in variation four with 0.6 % type F. As a final variation, with the same proportion of Lumajang sand and Bangkalan gravel of 5/10 and 10/20 combined with 0.3% additive type D and 0.6% additive type F. The capacity is compared based on physical properties and compression test. As a result, the best proposed design is variation three with a compression test over standard design with 29.44 MPa.]]>

<![CDATA[Public open space (POS) does not become an adequate priority in urban planning and design in developing countries, including Indonesia. The cities are almost ‘full of buildings’ and ‘less of POS.' Meanwhile, many studies show that the POS has a significant effect on citizens’ quality of life. By this situation, the research means to explore the quality of public open space in relation to its utilization. The study observed POS in several small towns in North Sumatra Province, where new urbanized area had been rising by autonomy regulation. A visual survey was carried out to record, map and identify the quality of the public open spaces. Besides, the visitors were interviewed to get their perception of the quality of POS. The investigation indicates that almost of public life did not always equal with the design of the POS. Almost POS have no pedestrian linkage to make it connect with the other urban space. Thus, the majority of POS was alienated with the other part of cities.There was no integration with public transport, too. The facilities were less of maintenance. However, the community kept coming to the place and doing many activities. The respondents perceived the POS as quite good, but not good enough. Still, they mostly believed that the POS have a real impact on their quality of life.]]>
