Purpose: The study’s goal was to analyze the adoption of online motorcycle taxi (in Indonesia it is called an ojek online) technology with the purpose to keep using the application.Methods: The study used the System Success Model to develop this research model. It was conducted based on the premise that information quality and system quality positively influence the ease and usefulness of the system application. The ease and usefulness of the system application have implications for user satisfaction and the intention to continue using the system. The study employed Structural Equation Modeling (SEM) using PLS (SEM) 4.0 to test and evaluate the measurement model and structural model. A sample of 235 respondents who are users of the online motorcycle taxi system in Semarang City was used in the study.Result: Out of 10 hypotheses tested, 9 hypotheses were accepted and 1 hypothesis was rejected. The usefulness of the system had a negative and insignificant influence on the intention to continue using the system. The intention to continue using the online motorcycle taxi application was strongly determined by the ease of the application system and user satisfaction. The discoveredings also showed that the quality of the system had the strongest influence on the ease of the system. Novelty: This study was unique in combining the Technology Acceptance Model and Mclean Delone approach to test the quality of the online motorcycle taxi application towards user satisfaction and intention to continue using the application.

Kata majemuk gabungan morfem dasar yang kesemuanya berstatus kata dengan pola fonetik, gramatikal, dan semantik tertentu sesuai dengan kaidah bahasa yang bersangkutan. Pola khusus ini membedakannya dari frasa atau kombinasi kata—kombinasi morfem yang bukan kata majemuk. Pembatasan ini berlaku untuk sejumlah dimensi, dan persamaan kosinus paling sering digunakan dalam ruang positif berdimensi tinggi. Misalnya, dalam pencarian informasi dan penambangan teks, setiap istilah secara tidak langsung diberi dimensi yang berbeda, dan dokumen diberi label sebagai vektor, di mana nilai di setiap dimensi sesuai dengan berapa kali istilah tersebut muncul dalam dokumen. Kesamaan cosine kemudian memberikan ukuran yang berguna tentang seberapa mirip dua dokumen dalam hal topik. Pada penelitian ini penggunaan kata majemuk sebagai kata kunci dalam pencarian dokumen menghasilkan dokumen yang lebih tepat. Data yang digunakan sebanyak 15 file. Data yang mengandung kata majemuk sebanyak 10 file. Data 5 dokumen tanpa kata majemuk. Hasil pencarian dengan menggunakan algoritma kesamaan menghasilkan nilai kesamaan yang tinggi, namun 33,3% kata majemuk tidak ada. Dan hasil pencarian dengan nilai kemiripan lebih rendah tetapi mengandung kata majemuk sebesar 66,3%. Sehingga dengan adanya penambahan data berupa kata majemuk di dalam pencarian membuat hasilnya lebih baik.

The growth rate of internet users in recent years has increased very rapidly and is growing rapidly. This triggers the creation of a new business model in the form of a marketplace that is used to buy and sell goods. This study aims to load an online store that is simple and lightweight but can meet the needs of sellers who use this website. Application development uses methods while the prototype in modeling the application uses use case diagrams, class diagrams, activity diagrams, and sequence diagrams. The research is expected to produce a web-based marketplace application that facilitates the transaction process of consignment providers and consumers at the Indonesian Helmet Shop. Furthermore, the design of this messaging service application prototype still needs to be developed in terms of user interface and user experience so that consumers can be more comfortable in transacting.

This research aims to create an Android-based search engine application using the Elastic-search algorithm which can later be used for students learning object-oriented programming. This media contains a search for material that makes it easy to learn and do assignments. The method used in developing this application is 4D from Thiagarajan and using Java language programming. The results of this study indicate that this application is valid for use in terms of Quality of visual and auditory perception, Ease of interaction and collaboration, Ease of learning to operate, Ease of use. It can be concluded that the Search engine application with Elastic Search algorithm is declared valid to be used as learning for students who want to learn about programming.
