Authors: Castillo Figueroa Enrique
Published: November 2018

La ciudad se considera una unidad político-administrativa, promotora del desarrollo económico, social y cultural para sus habitantes. En contraparte, los espacios periurbanos son configurados por la voluntad política en dotación de los servicios básicos. El caso de las colonias de origen ejidal: Lomas del Verde Ejidal, Jardines del Verde y Lomas de San Juan, en El Salto, Jalisco, México, muestra cómo la gestión hídrica, a través del capital social de sus habitantes, redujo la marginación a la que sus pobladores fueron sometidos durante 15 años, en  acceso al agua potable.

Authors: Hernández García Adriana , Sandoval Moreno Adriana
Published: November 2018

El objetivo del trabajo es abordar el ordenamiento administrativo de los años noventa que configuró en regiones el territorio de Jalisco y Michoacán, con el propósito de buscar mejores oportunidades de desarrollo y equilibrio económico. Aunado a  procesos rurales, en  polos urbanos se conforma una nueva política pública federal de decreto y conformación de zonas metropolitanas, impulsada en gran parte de México, como mecanismo de desarrollo que a la vez genere procesos económicos más equilibrados. La metodología utilizada en el estudio es un enfoque mixto, cuantitativo y cualitativo, a partir de métodos comparativo y deductivo, así como de técnicas de aplicación de encuestas, entrevistas, recorridos de campo, realización de mapas sobre los cambios locales de los recursos, entre otros. El estudio presenta cómo las regiones Ciénega de Chapala, de los estados de Jalisco y Michoacán, a casi dos décadas de su ordenamiento territorial, se han  ligado a procesos de constitución de zonas metropolitanas que favorecen intereses económicos de grupos de poder regional, pero con implicaciones en la transformación de dinámicas territoriales y desiguales para los pueblos ribereños y agricultores tradicionales.
Ultrasonic detection for tensile-shear strength of spot welding under different indentations based on wavelet analysis
Authors: Qiuyue Fan , Guocheng Xu , Ting Wang
Published: November 2018

Traditionally, the tensile-shear strength is detected using destructive testing. A viable non-destructive testing means, such as an ultrasonic technique, is necessary in the production environment to assess the tensile-shear strength. In this paper, electrode tips that were formed into
different sizes were used to obtain different spot weld indentations. The method, based on the echo amplitude of a faying surface, which is viewed as an effective method by previous studies, was proven to be limited when changing the size of the electrode tip, owing to the occurrence of a
spot welding structure with particular characteristics, ie an indentation and corona bond. The nuggets calculated, based on the echo amplitudes, were at the borders of the indentation, which increase with an increase in the size of the electrode tip. To address this issue, a wavelet function
was designed based on Chebyshev low- and high-pass filters, relating to the frequency and bandwidth parameters of an ultrasonic probe. The largest energy value from the approximate coefficient of five-level wavelet decomposition is used to distinguish the nugget, corona bond and indentation.
The nugget areas obtained, based on the largest energy value from the approximate coefficient, decrease with an increase in the size of the electrode tip and increase linearly with the tensile-shear strength.
Si buscas resultados diferentes, no hagas siempre lo mismo. Las organizaciones de gobernanza de los arquitectos españoles, 1931- 1990.
Authors: Echarte Ramos Jose María
Published: November 2018

Las organizaciones de gobernanza de los arquitectos españoles se establecen de forma definitiva en 1931 con la aparición de los Colegios Profesionales de Arquitectos. Estas instituciones y sus herramientas administrativas y profesionales dimanan, en buena medida, del gremio medieval, del taller artesano y el corporativismo franquista (heredero del primero) y mantienen un funcionamiento continuado y exitoso hasta 1973. A partir de esta fecha, los sucesivos cambios políticos, sociales y económicos que tienen lugar en el país alteran el equilibrio de un modelo profesional que hasta ese momento era prácticamente homogéneo. El periodo de 1970 a 1996, en que el sector comienza una liberalización que aún hoy continúa, supondrá, para los profesionales de la arquitectura españoles y sus organizaciones, un momento de análisis, de producción de información y de toma de posiciones ante una crisis endémica y un nuevo modelo de arquitecto y de ejercicio de la profesión para los que las herramientas de gestión del mercado profesional y sus instituciones no estaban preparadas. Los Colegios abordarán esta tarea introspectiva de formas diversas y sus sucesivas aproximaciones a la situación a lo largo de este periodo discurrirán entre la defensa del origen gremial, del modelo laboral y organizativo basado en el arquitecto liberal -el creador, en buena medida mitificado- y el planteamiento de cambios adaptativos acordes a la cambiante situación española; entre hacer siempre lo mismo y necesitar, cada vez de forma más urgente, resultados diferentes.
Anupama Kundoo. A call for action.
Authors: Paz-Agras Luz , López-Bahut Emma
Published: November 2018

Interview with the Indian architect Anupama Kundoo who develops her practice, research, and teaching in a strongly interconnected way. Her works starts from two principles: the low impact for the environment of her proposals and the strong contention that she establishes with the socioeconomic context in which they are.  Besides, she has developed her work in different cultural contexts around the world, which gives a wide view to the issues of contemporary architecture. From this point of view, Kundoo reflects a necessary approach of understanding Architecture that, ten years after the global economic crisis, moves away from the positions of the start architect system and faces the profession’s future from her personal attitude.

The purpose of the study was to assess the infection of tumor tissues with herpesviruses and human papillomavirus (HPV) in patients with squamous cell carcinoma of the larynx (SCCL) and to reveal the impact of viral infections of tumor tissues on the effectiveness of neoadjuvant therapy. DNAs of HSV1,2, CMV, EBV and HPV were studied by PCR in 26 samples of tumor tissues. We revealed a high level of herpesvirus infection in SCCL tumor tissues (up to 92.3 %), while HPV infection was less frequent – 19.2 %, including low-risk HPV (LR HPV, 11.5 %) and high-risk HPV (HR HPV, 7.7 %). Significant differences in the detection rates of the studied pathogens were found (p<0.05). EBV was more frequent (73.1 %), and HSV1,2 detection rate was the lowest (7.7 %). The prevalence of herpesvirus presence in tumor tissue in the absence of HPV was detected (p<0.05). The effectiveness of therapy was higher in patients without viral infections, compared to infected patients (100.0 vs. 80.0 %), but the difference was nonsignificant (p>0.05). There was no significant dependence of the chemotherapy effectiveness on the type of infection (p>0.05). However, the presence of LR HPV, HSV1,2 and especially combinations of herpesviruses with HPV in tumor tissues reduced the number of cases of tumor stabilization and regression which is notewor thy and requires fur ther research.

La educación intercultural como experiencia en la descolonización de los saberes
Authors: Alarcón Puentes Johnny Alberto , Fernández Soto Zaidy
Published: November 2018

Con el objetivo de analizar experiencias en la descolonización de saberes a partir de la enseñanza desde la Educación Intercultural, se aplicó el método etnográfico, a través del trabajo de campo, la observación participante y la entrevista a maestros tanto en Venezuela (Maracaibo) como en Colombia (Maicao). La investigación se fundamentó en el aporte teórico de estudiosos de la Educación Intercultural, tales como: Bonfil Batalla, Esteban Emilio Mosonyi, Xavier Albó y Catherine Walsh e investigadores decoloniales como Baoventura de Sousa y Santiago Castro-Gómez. La vivencia a través de talleres con maestros de escuelas con presencia indígena nos permite concluir que desde la docencia se pueden desarrollar y aplicar prácticas educativas que, lejos de la visión idealizada del indígena y a partir de la producción de conocimiento cotidiano y significativo con sus alumnos, con su comunidad, desde la cultura y sin la desestimación de saberes occidentales, pueden contribuir no solo con la no violencia epistémica, sino, mejor aún, con el propósito de participar en la co/construcción de identidades y la reafirmación cultural desde una perspectiva epistémica de la diversidad.
Investigation on some main glycosides content of Stevia rebaudian B. under different concentrations of commercial and synthesized silver nanoparticles
Authors: Majlesi Zohreh , Ramezani Moazzameh , Gerami Mahyar
Published: November 2018

Stevia rebaudiana B. extract as a low-calorie sweetener has gained worldwide approval. Synthesized nanoparticles by plant have been used in different programs such as medical, pharmaceutical and agricultural fields. Here, we report the increase of the main glycosides of stevia plant with silver nanoparticles (AgNPs) treatment. This fact has stimulated research on the analysis and comparison of different concentrations of commercial and synthesized AgNPs on the glycosides of stevia plant by highperformance liquid chromatography (HPLC). After AgNPs synthesis, spectrum absorption of extracts was analyzed in different ranges from 300 to 700 nm and the maximum peak was observed at 420 nm. Transmission electron microscopy (TEM) micrograph of synthesized AgNPs from Stevia rebaudiana extract showed spherical shape with the size of 25 nm. A comparison between quantities of glycoside by HPLC under both treatments of AgNP exhibited that synthesized AgNPs were more effective than commercial AgNPs on stevioside and then rebaudioside. On the other hand, results showed that increasing AgNP concentration in both treatments will lead to glycoside content enhancement. Overall, significant changes were observed in the glycosides in plants under synthesized and commercial AgNP treatment that could be used to create plants with higher quality of glycosides for pharmaceutical approaches.

Authors: Choi Hyojae , Kim JaMee
Published: November 2018

This research aims at analysing the usage of 3D Printing in education for school grades and suggest a way to encourage schools to use 3D Printers in Education. For this, a survey was done for 3,247 teachers in Gyeonggi Province on September. Usually schools are trying to buy 3D Printers to use it with software education courses. However with this survey, it turns out that teachers use 3D Printer with after school activities, creativity and experiential activities more than a regular courses. This is because there are not many teaching and learning materials for 3D Printers to be used with regular courses and it is hard for teachers to use 3D printers with professionality due to the fact that lack of the training. Therefore, to activate 3D printers in schools, not only budget support but also trainings for teachers and developing teaching and learning materials should be involved.

Augmented Reality to Promote Guided Discovery Learning for STEM Learning
Authors: Abd Majid Nazatul Aini , Abd Majid Nurfaizah
Published: November 2018

Augmented reality is one of the technologies that will impact teaching and learning. When augmented reality is applied in an educational setting, it can provide a superior learning environment because educators can add specific virtual information to enrich the existing learning materials or to create new learning materials that integrate the environment. Therefore, discussions on augmented reality applications for learning can be vastly found in the literature. Each application utilizes the resources available by using approaches appropriate for the learning outcome in question. The key problem with achieving learning outcome in analysing group one elements in a periodic table, is that some students have difficulties in visualizing an atom and what more to relate them with reactivity. The objective of this paper is to design and develop a learning application that supports science, technology, engineering and mathematics (STEM) education based on guided discovery learning to assist the students through questions based on exposure to various evidences via augmented reality. This application incorporates the use of 3D model of atoms and video of real experiments. To achieve the objective, action research is used to solve existing problem in a selected school. The application was evaluated by 25 students aged 16 years in a secondary school in Malaysia and has proven to be effective in  improving the students’ marks in tests conducted at the end of the application usage. The students can get many benefits from using the augmented reality based application because it supports Education 4.0 like flexibility in teaching and learning where learning is freed for the limitation of time, place and pace of study.
Serious Games for Post-Stroke Rehabilitation Using Microsoft Kinect
Authors: Shapiâ€™i Azrulhizam , Arshad Haslina , Baharuddin Mohd Syazwan , Mohd Sarim Hafiz
Published: November 2018

Traditional rehabilitation is a tedious task which typically reduces the patient’s motivation to perform rehabilitation exercises. Patients therefore need a program that can entice them to do rehabilitation exercises continuously. The proposed game includes two different types of game and three different types of movement for interacting with the game. The game was designed and developed based on the elements of a rehabilitation game and the types of movement in rehabilitation exercises. The interface was developed with the aim of increasing the motivation of players, and the design was based on an analysis of the technology constraints faced by post-stroke patients. Since these patients experience physical limitations, Microsoft Kinect was used for interaction in this game. Using Kinect, the patient is not bound by the controller to interact with the game.  Therefore, rehabilitation exercise games that support multi-player will provide a higher motivation than the single-player. Since most stroke patients suffer from cognitive impairment, cognitive challenge levels are also the key factors in the design of the game so that it does not become an obstacle for the recovery process.  This research develops a prototype of a rehabilitation exercise game that contains aspects of the social context, the type of movement and cognitive challenges. It also provides usability in game design, according to a post-stroke stage so that they can perform recovery activities based on their ability. In addition, this study highlights technology and rehabilitation exercise games in Malaysia.The game also adds a social context that gives patients the opportunity to have a friend to play either by competition or cooperation. The contribution of this research is to measure the effectiveness of Microsoft's Kinect game console and this game can help in recovery the post-stroke patients do additional exercises at home without the supervision of therapist.

Published: November 2018

Augmented Reality (AR) has proposed several types of interaction techniques such as 3D interactions, natural interactions, tangible interactions, spatial awareness interactions and multimodal interactions. Usually, interaction technique in AR involve unimodal interaction technique that only allows user to interact with AR content by using one modality such as gesture, speech, click, etc. Meanwhile, the combination of more than one modality is called multimodal. Multimodal can contribute to human and computer interaction more efficient and will enhance better user experience. This is because, there are a lot of issues have been found when user use unimodal interaction technique in AR environment such as fat fingers. Recent research has shown that multimodal interface (MMI) has been explored in AR environment and has been applied in various domain. This paper presents an empirical study of some of the key aspects and issues in multimodal interaction augmented reality, touching on the interaction technique and system framework. We reviewed the question of what are the interaction techniques that have been used to perform a multimodal interaction in AR environment and what are the integrated components applied in multimodal interaction AR frameworks. These two questions were used to be analysed in order to find the trends in multimodal field as a main contribution of this paper. We found that gesture, speech and touch are frequently used to manipulate virtual object. Most of the integrated component in MMI AR framework discussed only on the concept of the framework components or the information centred design between the components. Finally, we conclude this paper by providing ideas for future work involving this field.

Published: November 2018

Mental health detection in Online Social Network (OSN) is widely studied in the recent years. OSN has encouraged new ways to communicate and share information, and it is used regularly by millions of people. It generates a mass amount of information that can be utilised to develop mental health detection. The rich content provided by OSN should not be overlooked as it could give more value to the data explored by the researcher. The main purpose of this study is to extract and scrutinise related works from related literature on detection of mental health using OSN. With the focus on the method used, machine learning algorithm, sources of OSN, and types of language used for the mental health detection were chosen for the study. The basic design of this study is in the form of a survey from the literature related to current research in mental health. Major findings revealed that the most frequently used method in mental health detection is machine learning techniques, with Support Vector Machine (SVM) as the most chosen algorithm. Meanwhile, Twitter is the major data source from OSN with English language used for mental health detection. The researcher found a few challenges from the previous studies and analyses, and these include limitations in language barrier, account privacy in OSN, single type of OSN, text analysis, and limited features selection. Based on the limitations, the researcher outlined a future direction of mental health detection using language based on user’s geo-location and mother tongue. The use of pictorial, audio and video formats in OSN could become one of the potential areas to be explored in future research. Extracting data from multiple sources of OSNs with new features selection will probably improve mental health detection in the future. In conclusion, this research has a big potential to be explored further in the future.

Authors: Eissa Manar , Hashim Yumi Z. H Y. , Zainurin Nur Aimi A.
Published: November 2018

Currently, the long-term consumption of aspirin and non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) as anti-inflammatory medicines and pain relievers, have been reported to cause various side effects. Thus, natural compounds of several plant species including Aquilaria malaccensis have been explored as an alternative therapeutic source for inflammation treatment with regard to their safety and efficacy. Despite the accelerating rate on the research of agarwood leaf, the scientific evidences to elucidate the proclaimed pharmacological activities particularly anti-inflammatory activity are still limited. Therefore, it is the interest of this study to investigate the biological activity relating to the anti-inflammatory activity of A. malaccensis leaf extracted using Soxhlet and Supercritical Fluid Extraction (SFE) methods. Results showed that A. malaccensis leaf ethanolic soxhlet extract (ALEXB) gave higher yield (mg/g) of 98.33 ± 4.11 (9.83% wt/wt) as compared to soxhlet extract using hexane (ALEXA); 24.04 ± 5.27 (2.40% wt/wt) after 6 hours of extraction. Meanwhile, the supercritical fluid extract (SFEX) gave a relatively low yield of 12.57 ± 0.61 (1.26% wt/wt). The GCMS analysis revealed that 25, 30 and 16 compounds were detected in ALEXA, ALEXB and SFEX respectively with phytol as the major compound in the soxhlet extracts and n-hexadecanoic as a major compound in SFEX. Subsequently, in-vitro study showed that the extracts demonstrated inhibition of protein (albumin) denaturation in a concentration-dependent manner throughout a concentration range of 400-16000 µg/ml tested. Exclusively, the GCMS of leaf SFEX showed a peak of 1H-Cycloprop[e]azulene, decahydro-1,1,7-trimethyl-4-methylene (0.4205%), a tricyclic sesquiterpene that was testified to have potential analgesic and anti-inflammatory activity. Further research is warranted to explore the anti-inflammatory activities of A. malaccensis leaf extracts and their mechanism of action as an alternative halal ingredient for nutraceuticals and pharmaceuticals.

Authors: Samsudin Nurhusna , Hashim Yumi Z. H Y. , Arifin Mohd A. , Salleh Hamzah M.
Published: November 2018

Oil/water emulsion solvent evaporation method was employed to fabricate polycaprolactone (PCL) microcarriers. In order to produce porous microcarrier, the method was slightly modified. The porous network channels were generated inside the microcarrier by introducing camphene that was dissolved in the same solvent used to dissolve raw PCL. The evaporation of solvent and sublimination of camphene during the process of emulsion solvent evaporation method, produce solidified porous microcarrier beads. The surface porous microcarriers beads were further modified to make it competent for cell attachment and proliferation. The surface of these microcarriers were modified with UV/O3 system to introduce functional group and charge on the surface. The treatment followed with the immobilization of halal gelatin on the surface to imorove the biocompatibility of the microcarrier. Porous microcarrier with optimal size distribution was successfully fabricated. The average pore size of 11.74±8.32 µm was obtained with the concentration of 20% (w/v) of camphene. The porous PCL microcarrier was further tailored with gelatin through surface treatment with UV/O3 system and gelatin immobilization and validation of its compatibility towards mammalian cell was tested with cultivation of green monkyer kidney cell (Vero) in the suspension culture. Vero cells attach and proliferatie well on the gelatin coated porous PCL microcarrier with maximum cell number  of 3.90 í— 105 cells/ml as compared to cell proliferation on UV/O3 treated porous PCL microcarrier (1.83 í— 105 cells/ml). The developed microcarrier may be potentially applicable as a cell delivery scaffold for cell tissue culture and tissue engineering application.
Real Time Monocular Visual Odometry Using Hybrid Features and Distance Ratio for Scale Estimation
Authors: Nugroho Diky Septa , Ardiyanto Igi , Cahyadi Adha Imam
Published: November 2018

Real time dead reckoning navigation is important for supplying information of the current position of an autonomous mobile robot to complete its task, especially in certain areas such as hazardous and GPS-denied areas. Monocular visual odometry is a good choice as it is one of the dead reckoning navigation method which only uses single camera. For real time task, visual odometry requires fast feature extraction without ignoring its accuracy. Therefore, we propose the usage of a hybrid feature, i.e. Censure feature detector and upright SURF feature descriptor, as feature extraction. Yet, the scale ambiguity for the monocular visual odometry becomes a challenging problem. Without additional information from other sensors, estimating the scale is solely the only way. In our proposed work, distance ratio is employed to tackle such problems. Experimental results show the performance of the designed algorithm. A real example of running the proposed algorithm under an embedded device is also provided for demonstrating its real time capability.

Dye is an important factor in determining the efficiency of a dye-sensitized solar cell (DSSC) device. One of the dyes derived from natural resource is anthocyanin. At the same time, one of the natural resources containing anthocyanin is a tropical plant called mangosteen. In this work, the characteristics of anthocyanin extracted from mangosteen pericarps using different solvents have been examined. The anthocyanin was extracted from mangosteen pericarps using various different solvents, i.e. dry ethanol, ethanol containing 1% HCl, and ethanol containing 1% acetic acid. Absorption characteristic of dye extracted from different solvents was determined using ultraviolet-visible spectroscopy (UV-Vis). Fourier transform infrared (FTIR) was used to examine the functional groups of the extracted dye. Visible light absorption and photo-sensitizing characteristics of the extracted natural dye were then investigated through their applications in a DSSC device. The results from infrared characterization showed that all of the extracted dyes indicated the same tendency with the characteristic of anthocyanin. At the same time, the UV-Vis examination revealed that the dye extracted using solvent HCl 1% acidified ethanol was found to have a visible light absorption at a wavelength of 533 nm. This result indicated that HCl 1% acidified ethanol was the best solvent to extract anthocyanin from mangosteen pericarps. The activity of the DSSC device sensitized using the extracted dye through a photocurrent-voltage examination showed a power conversion efficiency of 0.23% and 0.18% for the device using the commercial dye and the mangosteen extracted dye, respectively. This result is quite convincing and promising for the next DSSC device development using natural dye extracted from mangosteen pericarps.

Textile wastewater contains a lot of pollutants which is hazardous if directly discharged. Coagulation and flocculation using inorganic salts were widely used to treat textile wastewater. However this method pose some drawbacks, such as high coagulant cost, large volume of sludge was produced, and potential health problems if the water is consumed. In this study we explore utilization of natural coagulant as an alternative to inorganic salts to treat textile wastewater. This study describes utilization of papaya seeds powder as a natural coagulant for synthetic textile wastewater of drimarene dark red (DDR) with initial concentration of 10 mg/L. The effect of coagulant dosage and pH to the %removal of colour in wastewater was studied using central composite design. The potential active functional groups in papaya seeds powder was characterized using Fourier Transform Infrared Spectroscopy (FTIR). It was found that papaya seeds powder contained -OH, -NH, C=O functional groups that indicate good potential as natural coagulant. The cubic model obtained was in good fit with experimental data, which was shown in R-squared value of 0.995. It was found that coagulant dosage, pH, and its interaction were significant to the removal of synthetic dye in wastewater. The decrease of pH gave higher %removal due to protonation of papaya seeds powder active coagulating agent resulting on better electrostatic interaction with dyes. The increase of dosage also gave increase in %removal until its optimum condition. After optimum condition, the %removal decreased due to colloid re-stabilization. The optimum condition was obtained at dosage of 0.57g/L and pH 1.97 with 84.77% of predicted colour removal and this result was in agreement with experimental response value.

Performance of microfiltration (MF) and ultrafiltration (UF) membranes to separate of folic acid from corn (Zea mays var. indentata) hydrolysate equipped in stirred filtration cell (SFC) mode were performed as a reference guide toward semi pilot scale. Separation on hydrolysate suspension of yellow dent corn (HSYCD) and hydrolysate suspension of white dent corn (HSWCD) as a results of hydrolysis of protease enzyme of Rhizopus oligosporus strain-C1 0.025 % and 0.075 % (w/w, dissolved protein) at pH 5 and 30 °C for 24 hours was conducted by MF (0.45 µm) and UF (100000 MWCO) membranes at stirrer rotation speed 400 rpm and trans-membrane pressure (TMP) of 20, 30 and 40 psia for 30 minutes. The experimental result showed that based on optimization of fluxes, the best performances of MF and UF membranes on HSYDC and HSWDC were achieved at TMP 40 psia and gave fluxes of 0.0534 and 0.0508 mL/cm2.min., respectively. In these process conditions, it take place an increase of folic acid in concentrates of HSYDC and HSWDC compared with before process (feed). Identification of molecular weight (MW) on folic acid from HSYDC and HSWDC displayed dominant folic acid monomer at T2.7, and T2.4 and T2.89. This matter showed that commodity of yellow dent corn has more potential use as source of folic acid compared with white dent corn at both similar condition of hydrolysis and separation and/or purification processes.

Aceh has experienced the critical event in three periods (political conflict, tsunami disaster, regular period) which they are different in risk characteristics. These critical events have inflicted on the sectors of life, including the construction sector. Some risk variables have been identified from previous studies that will be applied and analysis in this area by using risk assessment theory. In this research, we focus on the project risks in the three periods that it has an impact on the loss of profit on the contractors in Aceh. The potential risk variable and its pattern will be analyzed crossover in all the three periods. Qualitative risk analysis is used to describe the project risk of contractors who have conduct project in those periods. The potential risk variable, unofficial levies charges by bullies (P11), is the most extreme than other risks variables in the 1st period, has decreased in subsequent periods (2nd period and third period). The risk variable of P11 is the most avoided by the contractor because it is very influential on the achievement of the project objectives. This P11 variable not only emerged during the political conflict period but also in the post-tsunami period due to social, economic factors, although it has decreased. This P11 variable not only affects the risk singly but also could trigger the other variable, thus providing a double effect on project risks, such as increased costs for safety and security in project areas (P5) and Increased labor costs due to increased wages (P6). The result of risk analysis using qualitative risk analysis method with Risk Important Index (RII) shows that risk variable of P1 (Bureaucratic of the owner delays payment terms), P12 (Contractors shortage of funds caused by the cost overrun on the project), has experienced decreasing from 2nd period to 3rd period. However, the hypothesis results show that the decreasing is not significant. It indicates that this test is critical to include in risk analysis, especially on the method of qualitative risk analysis.

Foamed concrete is one of lightweight concrete innovations without coarse aggregates by adding foam to concrete mortar mixtures. The concrete was developed as a non-structural element in the building. This research utilizes rice husk ash (RHA) as substitute material for cement. This study determines the effect of foam percentage and the use of rice husk ash (RHA) on foamed concrete's microstructures. The percentage of used foam is 30%, 40%, 50%, and 60%, while the percentage of RHA substitution is 5%, 10%, 15% and 20% on cement. The use of RHA is to show the secondary reaction of cement to make new CSH. Tests conducted in this study include fresh concrete test, compressive strength of 28 days, and SEM test. Fresh concrete test includes slump flow test, and setting time. Research shows that the value of slump flow decreases with increasing percentage of foam and RHA substitution on cement. Percentage foam 30% to concrete volume with RHA 0% shows the maximum slump flow value, that is 63.25 cm. Setting time test results are increasing as the percentage of foam and substitution of RHA increases. The maximum setting time value is on 60% foam to concrete volume with RHA 20%. Percentage foam 30% with RHA 10% showed the maximum compressive strength value of 28 days at 7.77 MPa with density 1,378 kg/m3 and air void/bubble structure with smallest diameter.

This paper presents an estimation of demand and its comparison to the capacity of the existing tsunami shelters in Padang. A combination of horizontal and vertical evacuation plans was simulated with giving priority to the horizontal ones. Demand for the existing shelters was estimated with an assumption that the population is spreading uniformly within the administrative area. It was also assumed that the number of people who entered the area is the same as those who went out of the area at the time of the anticipated earthquake occur. The coverage areas of shelters were estimated based on the distance that can be reached by people within an effective available evacuation time. The capacity of the tsunami shelters was obtained from secondary data. The study found that almost half of the existing shelters in Padang will be overloaded if all of the people in the coverage area of a shelter being evacuated to the shelters. Addition of 37 more shelters with a capacity of 2000 is needed.

Dengue disease is one of the serious and dangerous diseases that cause many mortality and spread in most area in Indonesia. There are about 201,885 cases had been reported in 2016 including 1,585 death cases. The availability of nowadays clinical data of Dengue disease can be used to train machine learning algorithm in order to automaticaly detect the present of Dengue disease of the patients.  This study will use the Extreme Learning Machine (ELM) method to classify the dengue by using the clinical data so that first aid can be given which can decrease some death risk. The back propagation neural network is one of the popular machine learning technique that capable of learning some complex relationship and had been used in many applications. However, back propagation neural network still suffers with some limitations such as slow convergence and easily getting stuck in local minima during training. Therefore, this research proposed an improved algorithm known as ELM which is an extension of Feed Forward Neural Network that utilize the Moore Penrose Pseudoinver matrix that gain the optimal weights of neural network architecture. The proposed ELM prevents several backpropagation issues by reducing the used of many parameters that solves the main drawbacks of Backpropagation algorithm that uses during the training phase of Neural Network. The result shows that the proposed ELM with selected clinical features can produce best generalization performance and can predict accurately with 96.94% accuracy. The proposed algorithm achieves better with faster convergence rate than the existing state-of-the-art hierarchical learning techniques. Therefore, the proposed ELM model can be considered as an alternative algorithm to apply for early detection of Dengue disease.
