Abstract

Hoax news is a problem that needs to be addressed in Indonesia. Launching a report from Kominfo (Ministry of Communication and Information) in 2020 alone there were 3464 hoax news detected. considering the large number, it will be very difficult to identify every news that is in Indonesia, not quickly let alone comprehensively. Therefore, it takes a tool or system that can detect the news that is spread, quickly and efficiently. With this purpose, this research was carried out, using the method used by Multinomial Naïve Bayes (MNB). In previous studies, there are still some shortcomings that can be covered by improvisation. To improvise in the classification of hoax news, the MNB method was chosen for this study. MNB itself is a type of Naïve Bayes which is often used for text analysis where data is represented in the form of a word frequency vector. as a comparison rival for MNB, Gaussian Naïve Bayes will also be brought in for this research. with a total of 994 news data sourced from turnbackhoax.id and as a comparison this study also uses data from previous research which amounted to 250 news. The results obtained by the GNB method reach 94% accuracy and the highest accuracy for the MNB method is 96% which shows MNB is better.

Abstract

Planning activities in a project is a very important part because the planning is fundamental so that the project can run smoothly and the project can be carried out according to the specified time. The success or failure of planning a project can occur due to lack of planning and less effective control. As a result, the project is not efficient. In addition, it can cause delays, decrease the quality of work and increase implementation costs. In the project schedule planning step, the Project manager will determine the sequence of work activities carried out during the project, the work sequence and duration of the activities on the project are adjusted to the type of software project being carried out, so that the sequence of work activities and duration of work can be adjusted to the client's needs. In a company, good management is needed so that it can create structured work. PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) are mechanisms used to organize and sequence activities in companies that are complex and interdependent. This method has the advantage of analyzing projects in terms of estimating the project completion time by finding the critical path, identifying the start and end time of each activity to find the project schedule, and calculating the amount of slack time for each activity so as to minimize project delays. ID Core Indonesia is a company that was founded on October 20, 2018. A new digital startup in Malang city that focuses on software development services (project base). ID Core Indonesia focuses on developing information systems based on website technology and mobile apps. Based on the implementation of the CPM and PERT methods on the management system administration software project, the end-of-semester test of the ID Core Indonesia case shows the project completion within a period of 40 days with a probability of 82%.

Abstract

The CV. UD. Rejeb Ngalah is a company based in Nongkojajar. Rejeb Ngalah owns two SMEs that are developing and are kept for both SMEs. SMEs that are shaded by Rejeb Ngalah are Warnakarsa and Pesendaun located in Malang. This research is based on the researcher's desire to have and change for the better in society and to have a significant influence for better business processes than before. And we chose UD Rejeb Ngalah as a place of research because it had several problems experienced and it made the researchers intend to improve the processes in it. The main problem with Rejeb Ngalah is that between UKM Warnakarsa and Pesendaun, production and administrative activities are currently still carried out in different places and there are often misunderstandings among employees who handle administrative activities at Rejeb Ngalah because there is no warehouse information system for goods so that employees sometimes incorrectly inputting item data and causing the job-desk not to be properly organized as it should be. Because of the digital revolution, if a company wants to improve operations, it must develop new, more efficient business models [1]. Therefore, this research was conducted to develop an information storage system at UD. REJEB NGALAH to make it easier for employees to record goods, clarify the SOP of each employee and all administrative activities can be well organized. The research uses the prototyping method because it will be very effective if the client does not know what the website will actually be like. And at the wireframe/prototyping stage we can present what kind of website description is suitable for clients. The prototyping method can connect directly between developers and users with prototypes that have been designed before being implemented into coding so that the functionality of the system can be clearly described from the prototype [3]. It is certainly more effective for developers not to need to do coding before the user fits the system that has been described through the prototype.

Abstract

E-Learning merupakan pembelajaran berbasis web yang bisa diakses dari internet, sehingga dengan adanya E-Learning ini dosen dan mahasiwa bisa lebih mudah dalam proses pembelajaran. E-Learning juga sudah mulai diterapkan pada pendidikan tinggi khususnya di Universitas Muhammadiyah Malang dengan menggunakan moodle, edmodo dan google classroom. Karena penggunaan e-learning di lingkungan Universitas Muhammadiyah Malang masih belum masiv, perlu melakukan evaluasi dengan mengukur penerimaan dan perilaku pengguna e-learning. Metode untuk melakukan evaluasi menggunakan TAM dan TPB (C-TAM-TPB) yang merupakan model dari Yung – Zug Chang. Pengujian dipenelitian ini menggunakan SEM dengan aplikasi SmartPLS. Hasil dari penelitian ini, penerimaan e-learning pada pendidikan tinggi dapat diterima dengan baik dan perilaku pengguna e-learning juga berpengaruh terhadap penerimaan karena antar variabel saling berpengaruh signifikan. dari penjelasan tersebut, hal yang dapat dilakukan peneliti ialah merekomendasikan penggunaan e-learning secara masiv dikarenakan sangat membantu dalam pembelajaran, hal ini dapat dilihat dari tingginya nilai siginifikasi hipotesis perceived ease of use terhadap perceived usefulness sebesar 52%. Tetapi ada hal yang harus diperbaiki supaya penggunaan e-learning bisa optimal, yaitu penyesuaian fitur terhadap SN DIKTI terkait pembelajaran jarak jauh. Saran ini berdasarkan rendahnya hasil nilai signifikasi hipotesis perceived usefulness terhadap behavior intention sebesar 18%.
