Abstract

The use of early warning system is potential adaptation options to reduce the impact of the climate variability and change.  This study aims to develop a dengue early warning model using climate information.  The model was developed through three steps of analysis.  First step was to determine the length of periods used in prediction and optimal time for eradicating Aedes aegypti mosquito’s breeding sites.  Second step was to identify the best prediction model of dengue incidence rate (IR).  Third step was to develop an early warning model using stochastic spreadsheet.   It was found that the best predictors for predicting dengue incidence rate at week-n (IRn) were (1) rainfall index with two weeks lead time (ICHn-2).  The rainfall index of week-nth is a function of three week moving averages rainfall (CH3), i.e. (CH3n-1.155*CH3n-1+0.702*CHn-2), and (2) IR with one week lead time (IRn-1).  The IR model prediction was IRn = 0.795*IRn-1+0.067*ICHn-2 with R2=76.6%.  These models (result model from first and third step) can be used to provide early warning on optimum time for controlling the mosquito’s breeding sites and the need for fogging action in order to avoid the dengue incidence rate beyond the critical limit defined by the Ministry of Health

Abstract

The digital technology has permeated almost every aspect of life. Meanwhile, the responses from the field of language teaching in Indonesia to this new development have been scarce. The paper aims to provide an answer to the question whether language teachers perceive Information and Communication Technology (ICT) as a threat or a helpful assistant. To achieve this, a survey was conducted to 110 English teachers in Java, Indonesia. Five closed-ended items and two open-ended items in an online questionnaire asked them several questions about what conditions they see as threats, how they perceive ICT, and what digital facilities they have been using in their work. The results show that most of them perceived ICT positively, seeing it as a beneficial rather than threatening force. To them, ICT has been an attractive source that provides learning resources, fosters communication and collaboration, and spices up teaching-learning activities. Those who expressed their worry over ICT mentioned the importance of teachers’ upgrading their ICT skills and called for institutional support for the teachers. Three models, TAM (Technological Acceptance Model), UTAUT (Unified Theory of Acceptance and Use of Technology), and TPACK (Technological Pedagogical Content Knowledge) were then discussed to address the need for helping teachers adapt to the fast-changing digital technology.

Abstract

Building Information Modeling (BIM) has attracted ever increasing attentions from construction industry stakeholders around the world including Malaysia. Numerous studies have been conducted in exploring the benefits of BIM and proposing strategies for BIM implementation. However, to convince the industry stakeholders to implement BIM technology is relatively challenging. Tangible evidences are needed to bring up the industry’s acceptability towards the technology. In Malaysia, the Construction Industry Transformation Programme (CITP) has been developed to drive the transformation and development of the construction industry. One of the cases highlighted in the CITP is on the limited adoption of information technology such as BIM. Therefore, currently the Malaysian government is actively engaging with construction industry stakeholders to encourage the BIM implementation. This paper aims to propose a framework of BIM implementation stages in the construction industry of Malaysia. Three case studies have been analysed as a fundamental study to develop the framework. The results show that two of the companies are at the adaptation stage and one of the companies is at the application stage. At this point of time, the results indicate that the companies are more comfortable to experience only some part of the BIM benefits compared to fully utilise the technology. Fundamentally, the companies will only be at the adoption stage once the confidence level towards the technology is increasing and the companies will be categorised in the application stage when the companies are able to perform knowledge transfer related to BIM technology. This implementation stages can be used as an indicator to predict the direction of BIM in Malaysia. Thus, to ensure the successfulness of BIM implementation, there is a need to understand the current stages of company’s BIM implementation and propose the criteria needed for a company to move from one BIM stage to another.

Abstract

The importance of usability can determine the success or failure of the web application. Conventional approaches of usability evaluation methods only consider the average score from usability assessment which represents the frequency of problems from users when using the website. Another approach to measure the impact of usability factors can be calculated using the method of Partial Least Square. The case study show that combining between this two approaches (average score of usability assessment and impact of usability factors) can be considered for decision makers in prioritizing factors usability.

Abstract

Today, the usage of food additives can be found in nearly every food, especially in packaged foods. Meanwhile, the majority of people are unaware of the impact of the use of food additives in the human body when consumed freely. One of the easiest ways to determine the ingredients of a packaged food,  is to read the label of product composition. If it is doubtful, then the product was not consumed. However, public knowledge about food ingredients listed in the product composition is generally relatively low. So, even if they could determine the ingredients of the packaged food products, but still do not know the impact of their use. In this research, built an Android app of Food Additives Glossary that presents information about each type of food additives. This app has a barcode scanner and decoder using ZXing library to facilitate the acquisition of data from the food additives listed in packaged foods. User reads the barcode of packaged food products using the barcode scanner. This applications will display of food additives contained therein. Furthermore, the user can select one of the food additives and the application will display some information, such as: INS code, category (safety, unhealthy, dangerous), ADI (Acceptable Daily Intake) limits, side effects and further description of the food additives.

Abstract

IT investment decisions made by the company have uncertain value characteristics; have a high risk than other capital investment failures and intangible benefits of expected. In this situation, effective decision making is an important (perhaps most important) part of managerial activity. In this article, we analyze the influence of decision making under uncertainty, company size, and environmental hostility to intuition and analyze the intuition of company performance. There are five companies as study sample (ie: university, hospital, regional owned enterprises, creative industry, and software house industry) in East Java, Indonesia. The method used was a survey. The respondents were Top Level Management that is responsible for IT investment decision. Data analysis techniques used was Structural Equation Modeling-Generalize Structure Component Analysis (SEM-GSCA). Although intuition process is critical for effective IT investment decision making, we found that: (1) decision making under uncertainty and environmental hostility did not affect on intuition; (2) company size has a positive effect on intuition, and (3) intuition has a positive effect on company performance
