Abstract

The most common problem faced by kids is the difficulty to sight-read a music score.On the other side, nowadays kids love to learn by playing games in the form of mobile applications. Unfortunately, currently available mobile-based music games tend to target adults, hence not so appealing and therefore more difficult to learn. Considering the difference between every children’s ability, this application is using Fisher-Yates Shuffle algorithm for problem shuffling in each level and also the principal of decision tree for problem choosing based on the problem’s weight and children’s ability. As a solution to the problem stated above, this study is conducted by the design of “Adventure in Music Land”, an Android-based music theory education app specifically designed for kids aged 9 – 13. This application is being used to help kids improve their sight-reading ability.

Abstract

Agar sebuah negara makmur entrepreneurship sangat penting artinya. Salah satu faktor penentu utama dalampeningkatan jumlah entrepreneur adalah sistem pendidikan yang dirancang melalui analisa yang tepat terhadap kekuatan,kelemahan, peluang dan tantangan yang dihadapi oleh institusi pendidikan di Indonesia. Teknologi Informasi (TI) adalahbidang yang menarik minat banyak orang untuk melakukan proses entrepreneurship karena barrier to entry nya yangtergolong rendah dimana investasi lebih banyak bersumber kepada kekayaan intelektual sehingga tidak tergantung padamodal yang besar. Pendekatan yang dilakukan untuk Entrepreneurship dibidang TI memiliki perbedaan yang mendasardibanding dengan bidang lain yang membutuhkan investasi mesin-mesin pabrik dan lokasi fisik. Untuk mendukungkeberhasilan menciptakan entrepreneur dibidang TI, maka sasaran pembelajaran harus mencapai kemampuan mencipta,sehingga metode pembelajaran yang berbasis proyek merupakan pendekatan yang dianggap penting ketimbang modelceramah.

Abstract

Data science competence is still quite uncommon for most people, even though this competence is very important in managing business development strategies in various leading industrial fields. Through data science, companies can find patterns, perform clustering, calculate predictions more accurately to make decisions that have an impact on company excellence. Lack of knowledge about data science, researchers seek firstly in the industry to explore tools that are mostly used, convenience, challenges, measuring success tools and advantages. In this study, the researchers conducted a Focus Group Discussion by interviewing resource persons who worked as Data Scientists. Interview method to discuss aspects of Demographics, aspects of Technology-Task Fitness, and aspects of the Technology Acceptance Model. The results of this study conclude that the tools that are the mainstay of the industry in Surabaya and its surroundings area are Jupyter Notebook, Python, and Tableau.

Abstract

Team climate in organization is an important element to make the innovation process in an organization works. Study on team and its behaviour is done extensively around the world. It shows the importance of a team. Team climate is one of the characteristics of an innovative team. Team Climate Inventory is a measurement scale to examine the climate factors in a team. Earlier TCI was developed by West in 1990 and then extended in 1995 and 1998. Kivinaki and Eloainio made a shorter version of West’s which consists only 14 items. The shorter version is administered to a total five teams of co-working space start-up. The technology start-up has an intensive program every day within a month under a supervision of tutor from international wellknown company and an entrepreneurial-based university. The quantitative survey was followed by interviewing some of the member and leaders of the start-ups. The item analysis shows that all items are accepted with CITC value are above 0.3. And high reliability with Cronbach’s alpha value is above 0.8. The analysis shows that TCI has 3 factors, which consist of vision, participatory safety, and support for innovation. Keywords: Team Climate, Innovation, Technology start-up

Abstract

The digital transformation in the stockbroker industry has led to a significant increase in retail investors, who often lack the expertise to analyse stocks thoroughly. This research addresses the challenge by proposing a classification model to predict stock ratings such as "Reduce", "Hold", "Moderate Buy", and "Buy”, allowing retail investors to make informed decisions. The data analysed is collected from the S&P 500 index through web scraping using Beautiful Soup, resulting in a dataset used for training and testing the classification model. Popular stock indicators are used as attributes in predicting the rating of the stock, which includes the Exchange, Price, Volume, Market Cap, ROE, ROA, P/E Ratio, EPS, Annual Sales, Net Income, Net Margins, and PB Ratio of the stock. The models selected for classification include K-Nearest Neighbors (k-NN), Gaussian Naive Bayes, Support Vector Machine (SVM), Decision Tree, and Random Forest. GridSearch is employed to maximize each algorithm's parameters for optimal performance. Results indicate that the k-NN model outperforms others, achieving the highest accuracy (0.618644) and weighted F1-score (0.605011). However, all models exhibit relatively low accuracy, suggesting the complexity of predicting stock ratings due to external factors not considered in the study.
