Abstract

In the determination of employees who have the achievement required assessment of the assessment. There are several policy setting criteria to be able to prevent subjective decision-makers such as the influence of "likes and dislikes", so it is often wrong to judge employees. This paper is intended to provide a solution to the problem of choosing qualified and qualified employees using the AHP method and using decision support systems application Expert Choice to assist decision making in determining outstanding employees based on MBO method references. From the result of comparison of criteria weight that has been inputted and has been adjusted with comparison matrix Sub Criteria of Achievement then got that occupy the highest priority data that is consumer satisfaction with point 0,434, discipline with point 0,285, operational performance with point 0,071 and achievement with point 0,058 with inconsistency 0, 03 with 0 missing judgments.

Abstract

Requirements engineering is a series of activities which aims to elicit, analyze, evaluate, and document the requirements of a system that is being developed. The activities do not stop after the product is deployed but continues as the users use the product and provide feedbacks to the system and matter how decent the functionalities of a product are, if it cannot address the correct problem and/or opportunities of the stakeholders or users, the product cannot be considered useful. That being said, not all stakeholders are willing to participate in providing useful feedbacks to improve the product after deployment, for many reasons. Gamification is considered as an opportunity that can be utilized to improve the motivation of user to use a product by implementing game design elements into an existing software product, thus increasing user participation to contribute in providing useful feedbacks and evolving requirements of a software product. This research proposes a model to support engineers in motivating users to provide feedbacks using gamification and also Naïve Bayes Classifier to classify user feedbacks into categories needed by the developer to extract the requirements stated in the feedback, such as bug reports, feature request, user experiences, etc. Kata Kunci—requirements engineering, gamification, Naïve Bayes, user feedback

Abstract

Tuberculosis is an infectious disease caused by mycobacterium tuberculosis. It can affect some parts of the body: lungs, lymph nodes, intestines, kidneys, endometrium, bones, and brain. According to the survey of tuberculosis prevalence conducted by Republic of Indonesia Ministry of Health in 2013-2014, Indonesia was the second country in the world with the most case of tuberculosis. It makes Indonesia become a country with emergency in lungs tuberculosis. An expert system for lungs tuberculosis detection is built to help people detecting the possibility of suffering from lungs tuberculosis. Therefore, it is hoped that the lungs tuberculosis patient can have early treatment. Certainty factor is used to solve the uncertainty problem delivered by the doctor when examining the patient. Thus, certainty factor is an appropriate method to be used in the expert system for detecting certain disease. This method has been correctly implemented, proved by comparing system detection result to manual calculation result. The expert system has 81.25% accuracy, 83.49% success using DeLone and McLean model, and a cronbach alpha of 0.82 which indicates a good reliability based on the indicators used in the questionnaire. Index Terms— Certainty Factor, Disease Detection, Expert System, Pulmonary Tuberculosis, Situsparu

Abstract

Community-based question answering (CQA) is formed to help people who search information that they need through a community. One condition that may occurs in CQA is when people cannot obtain the information that they need, thus they will post a new question. This condition can cause CQA archive increased because of duplicated questions. Therefore, it becomes important problems to find semantically similar questions from CQA archive towards a new question. In this study, we use convolutional neural network methods for semantic modeling of sentence to obtain words that they represent the content of documents and new question. The result for the process of finding the same question semantically to a new question (query) from the question-answer documents archive using the convolutional neural network method, obtained the mean average precision value is 0,422. Whereas by using vector space model, as a comparison, obtained mean average precision value is 0,282. Index Terms—community-based question answering, convolutional neural network, question retrieval

Abstract

Permasalahan pada sebuah jaringan terus berkembang seiring dengan peningkatan jumlah jaringan yang terbentuk. Peningkatan jumlah jaringan terjadi karena peningkatan jumlah dan jenis dari pengguna jaringan. Hal ini menyebabkan sistem yang ada sekarang harus terus disesuaikan dengan kebutuhan pengguna jaringan. Salah satu yang terus digunakan adalah algoritma TCP untuk mengatur pengiriman data, paket drop dan congestion window. TCP yang biasa digunakan masih dianggap kurang efektif dalam melayani pengiriman data terutama jika terjadi banyak paket drop. Jika banyak terjadi paket drop otomatis waktu yang dibutuhkan sebuah paket untuk sampai pada tujuan akan membutuhkan waktu yang lebih lama. Untuk itu dilakukan beberapa percobaan untuk mencari solusi yang bertujuan mengurangi drop. Salah satunya adalah dengan memodifikasi algoritma TCP. Solusi yang dijabarkan adalah dengan menambah parameter decrease dan increase yang mampu mengatur congestion window sedemikian sehingga mampu mengurangi drop. Index Terms—Congestion window, paket drop, parameter increase dan decrease, TCP

Abstract

Data acquisition is an important part of a series of activities in a wind tunnel test and determine the validity of aerodynamic characteristics information of the test object. One of the factors which affect the success of the data acquisition process is the control of the data acquisition parameters prior to the execution of the wind tunnel test. A large number of data acquisition parameters, and the configuration complexities of the data acquisition parameters, which are still managed manually, urged the development of a software which is expected to facilitate the management of these parameters in a way that is friendly to use and integratable into the existing data acquisition system. Engineering of data acquisition parameters management software was then carried out through the analysis, design and implementation stages in an iterated manner, starting with a simple prototype toward the establisment of operational product.
