Abstract

Sentiment analysis as part of text mining research domain has been being recognized due to the successful implementation in social media analysis. Sentiment analysis methods had intelligent ability to classify texts into negative or positive. Classified texts concluded whole users respond and described opinion polarity about particular topic. Based on this idea, this research took e-learning’s users opinion as object to be measured through sentiment analysis. The results can be used to evaluate the e-learning activity. This research had been implemented in Widyatama University which had been running e-learning activity for several years. Qualitative method by given questioner to users and gather the feedback is commonly used as evaluation of e-learning system previously. Still, questioner doesn’t represent the conclusion about the whole opinion. Hence, it needs the method to identify opinion polarity from e-learning member. The e-learning opinion data sets were gathered from questioner filled by e-learning member included both student and lecturer as participants. The participants gave review about learning outcome after their participation in e-learning activity. Their opinion was needed to describe current situation about e-learning activity. Therefore, the conclusion could be used to make improvement and described few achievements about the e-learning system. The data sets trained by Naïve Bayes classifier to group each user respond into negative or positive. The classification results were also evaluated by a number of particular evaluation metric used in data mining to show the classifier performance such as accuracy, precision, and recall.

Abstract

Student in Faculty of Psycho­logy think that Statistics is very difficult for them, because Statistics is viewed as a hard science than Psychology which is viewed as a soft science. Various attempts have been made to improve student atti­tudes toward statistics, so that student ha­ve more positive attitudes. One of the ef­forts is to transform the curiculum of Sta­tistics in Faculty of Psychology UniversitasPadjadjaran by adding SPSS (Statistical Packages for Social Sciences) practicum courses since 2009. There are a variety of data analysis con­tained in SPSS can be used for data pro­cessing. However, there are still some sta­tistical data analysis used by students of the Faculty of Psychology that is not ava­ilable in SPSS. The aimed of this research is to develop software namely UniversitasPadjadjaran Statistical Analysis Series, which is statistical data analysis software that consist analysis that does not exist in SPSS or other data analysis software. In this preliminary research, modules are de­veloped only for Database Management and Descriptive Statistics.The software development will be carried out by (SDLC = Software Development Li­fe Cycle). SDLC is a series of step or phase that presents a model for development and lifecycle management software or applica­tions.The resulting software is tested on 144 stu­dents in Psychology Faculty in UniversitasPadjadjaran. The trial results showed that the software is most appropriate and "user friendly" software.

Abstract

Paper-based correspondence has many constraints on sending, receiving, and filing. The filling makes it difficult to search document.  The purpose of this research is to facilitate the process of sending, searching, and integrating data and documents. With electronic-based office mail is expected to reduce paper usage. Application development methods using the SDLC method consist of system investigation, analysis, design environments, testing, training, and transition, operation and maintenance.Electronic-based office mail is able to solve many problems regarding the mail system such as speed of delivery, filing, and searching of documents. By utilizing the database system, documents can be stored well and integrated. It's cannot eliminate the use of paper. The main reason is the habit of employees needed paper evidence in their work

Abstract

Currently the learning process cannot be separated from the exchange of digital information and online interaction. Initially using computer technology and internet, then growing with the existence of mobile phone technology. The demand of Digital Learning for efficient and environmentally friendly energy is very important and urgent because of the increasingly expensive price of fuel and the high utilization of mobile phones as a learning tool for the society. Our government itself supports the discoveries, researches, and technologies that use renewable energy such as energy from sunlight and biomass energy. The city of Manado which located in North Sulawesi province has a good hot climate every year and a fairly high solar energy. This is very good if it can be used as a source of energy for certain equipment such as mobile phones. This paper describes a basic research that has been done where the energy of sunlight becomes alternative energy to charge a mobile phone. The research method is literature study, theory comparison, block diagram design, assembly, and testing. The results obtained give hope that in the future there are opportunities to develop further research and design a solar energy source for mobile phones charging, by using solar cells that have specific current and voltage specification.

Abstract

Internship is an undergraduate activity for gaining working experiences.  Hence, it is expected that some universities convert it as an undergraduate course. In our university, registering internship topic is automated using a web-based portal; it takes tremendous effort if done manually. Nevertheless, according to our informal survey, existing portal suffers a lot of limitation, resulting user dissatisfaction. This paper presents a further development of such portal by following phases described in Application Lifecycle Management. According to three evaluation scenarios (black-box, small-group user, and large-group user testing), proposed portal works well and fits user need.
