Abstract

Models with sample-selection biases are widely used in various fields of economics such as labour economics (see Maddala, Amemiya, and Mroz). The models are usually estimated by Heckman's two-step estimator. However, Heckman's two-step estimator often performs poorly (see Wales and Woodland, Nelson, Paarsch, and Nawata). The data used in this study originated from the survey was conducted by the National Population and Family Development Board of Malaysia under the Ministry of Women, Family and Community Development of Malaysia, called the Malaysian Population and Family Survey 1994 (MPFS, 1994).  The survey was conducted through a questionnaire, were randomly and specifically for married women. The data set focus on married women which provides information on wages, educational attainment, household composition and other socioeconomic characteristic. The Original sample data based on Mroz (1987), there are 4444 records married women. It is necessary to use the maximum likelihood method to estimate the models in such cases. For solving uncertainty data of  a parametric sample selection model, in this paper needs to consider the models estimation using fuzzy modeling approach, called Fuzzy Parametric Sample Selection Model (FPSSM). Fuzzy Parametric sample selection model (FPSSM) is builds as a hybrid to the  conventional parametric sample selection model. Finally, the result showed, FPSSM by Maximum Likelihood Estimator (MLE) estimates of the mean, Standard Deviation (SD).   Keywords:    Econometrics, Fuzzy Number, Heckman Two-Step Estimator,  Married Women,  MLE, Non-participation, Sample Selection Model.

Abstract

With qualified data or information a better decision can be made. The interval width of forecasting is one of data values to assist in the selection decision making process in regards to crime prevention. However, in time series forecasting, especially the use of ARIMA model, the amount of historical data available can affect forecasting result including interval width forecasting value. This study proposes a combination technique, in order to get get a better interval width crime forecasting value. The propose combination technique between ARIMA model and Fuzzy Alpha Cut are presented. The use of variation alpha values are used, they are 0.3, 0.5, and 0.7. The experimental results have shown the use of ARIMA-FAC with alpha=0.5 is appropriate. The overall results obtained have shown the interval width crime forecasting with ARIMA-FAC is better than interval width crime forecasting with 95% CI ARIMA model.

Abstract

SMK Telkom Bandung is one of the educational institutions under the Telkom Education Foundation called Telkom Schools. As a school that has a mission to implement information system based on Information and Communication Technologies (ICT) for learning media, SMK Telkom Bandung must have an information system that can process student data related to student absences and grades. The management of absence and grade of student is not efficient because in once assesment process still requires a long time, there are a lot of errors in the sum result and data loss. Where these data are used to measure of the progress of student achievement. Therefore, it is necessary to develop a monitoring system for students who can deliver absent report and student grades to parents quickly through SMS Gateway notifications to help monitor the teaching and learning process in schools. This information system was developed using the SDLC prototype and PIECES analysis approach by integrating Gammu SMS Gateway as a notification feature. In the testing phase using black box testing the results show that the system can documentation absent and grades in a structured manner, be able to convey student attendance report information and grades quickly, teachers can present and evaluate attendance report and reports and grades accurately, as well as with the SMS Gateway notification parents can help monitor the teaching and learning process at school.

Abstract

Economic demands make working mothers currently a trend in society, especially in DKI Jakarta. The dual role of a mother makes it difficult for them to divide the time to take care of the child, especially if the child is still at the age of a toddler. Along with this, the existence of a Daycare is increasingly needed as an alternative parents to take care of their children while they are working. Therefore, in this study a web-based Daycare search application will be created that can help parents search for Daycare in DKI Jakarta. This application uses the Content Based Filtering method that is by providing recommendations based on the similarity of criteria between Daycare that are being seen in detail by Parents and Daycare who have been given a rating by them with other Daycare available in the system so that it can be a comparison for Parents in choosing Daycare. The results obtained from this study are made with an application that applies the Content Based Filtering method that supports the "Daycares You May Like" feature in the application for the highest similarity Daycare with Parents details being seen as a recommendation tool in this application. After doing the research, it was concluded that by using the Content Based Filtering method the system can display Daycares that has similarities based on its facilities.

Abstract

It's very rare to find people who can easily read the Koran, dhikr and give alms especially for workers. Busy activity makes them feel difficult to do religious activities, especially if they have to carry the holy book Al-Quran and Tasbih. along with these problems the presence of technology is very much needed as an alternative to the holy book of the Koran to uphold the community in carrying out their worship activities in their preoccupations. Therefore, in the current research an application will be made as a Tool and Guidance for Islamic Worship, an application that can help the community more easily in conducting worship activities reading Al-Quran and Dhikr. This application uses the RAD (Rapid Application Development) method. From the results of this study produce a Zipedia application by implementing a Rapid Application development method, the conclusion that with the Rapid Application development method can produce Islamic applications that can facilitate the community in worshiping, the conclusion that with the RAD method in conducting worship.

Abstract

Mobile healthcare application (mHealth app) assists the frontline health worker in providing necessary health services to the patient. Unfortunately, existing mHealth apps continue to have accuracy issues and limited number of disease detection systems. Thus, an intelligent disease diagnostics system may help medical staff as well as people in poor communities in rural areas. This study proposes a scheme for simultaneously selecting the best neural network models for intelligent disease detection systems on mobile devices. To find the best models for a given dataset, the proposed scheme employs neural network models capable of evolving altered neural network architectures. Eight neural network models are developed simultaneously and then implemented on the Android Studio platform. Mobile health applications use pre-trained neural network models to provide users with disease prediction results. The performance of the mobile application is measured against the existing available datasets. The trained neural network engines perform admirably, detecting 7 out of 8 diseases with high accuracy ranging from 86% to 100% and a low detection accuracy of 63%. The detection times vary from 0.01 to 0.057 seconds. The developed mHealth app may be used by health workers and patients to improve resource-poor community health services and patients' healthcare quality.
