JNT Ekspress is one of the many freight forwarding companies that exist today, where JNT has very wide access so it is very easy to use for the public in shipping goods. With the current network, JNT is able to deliver goods to all provinces in Indonesia. With the large number of users, of course there will be a lot of user opinions that appear, both positive and negative opinions. In order to be able to categorize multiple opinions, a machine learning program is needed that can simplify the process of grouping the opinion. There are many algorithms that can be used to classify opinions, one of them is Decision Tree. Prior to grouping or classification, Tweet data that has been collected needs to be preprocessed first so that the tweet data can be recognized by the system. Based on this research, the Decision Tree algorithm gets an accuracy of 94.12% with a comparison ratio of training data and testing data of 90:10

Report recording system and product sales that have been carried out at PT. Officer is still manual by using the Microsoft Excel application which is done by the admin of PT. Officer which is considered very risky in data storage. In addition, if the customer comes directly to the store, the customer must wait at least 30 minutes for transaction processing because the admin is still processing it manually. With the creation of a Sales Information System at this Web-Based PT. Officer, it is hoped that it can help all parties to process the data. Data processing starts from the admin who can add products, edit products and delete products that are directly connected to the database. And customers can make product purchase transactions.This system was developed using Visual Studio Code, PHP, CSS, XAMP V3.3.0 and MYSQL applications. The method used or used in this information system is the Waterfall Method. With this website, transactions and sales reports can be processed in a structured manner and the security system can be guaranteed because it is stored in the database. This website is designed to assist customers in providing the desired product. The results of this information system can simplify the ordering process and the sales process.

As part of the annual community service to help improve the school students' English skills, Technocrat Foreign Language School Tangerang conducted a community service in The Four State Vocational High School in Tangerang Regency, Banten. The English training emphasized improving the students' English communicative skills and their interest in practicing the language. The survey research, which succeeded in the training, indicated some important findings, such as the positive perceptions toward the English training, the perceived importance of English for the student's future careers, the importance of English subjects/courses in higher education as well as in employment. Specifically, the role of English in the hospitality, service, retail, and creative industry will be imperative. Of the four skills, speaking was deemed the most important skill to learn for employment. Concerning their future career, the students expected to have a non-English teaching career after graduating from college. The present study attempted to highlight the issue of the English training, potential employability, and the perceived important skill needed by the vocational high school graduates so that they can have more chances to work in the above industries. Further study should identifiy more skills specifically needed in the above industries so that the amount of unemployment from vocational high school graduates can be reduced.

Aplikasi Smart Campuss telah digunakan secara luas oleh mahasiswa Unisbank, namun masih ditemukan berbagai keluhan terkait kemudahan penggunaan aplikasi sehingga diperlukan evaluasi serta analisis pada aspek usability. Penelitian ini bertujuan untuk mengukur tingkat usability aplikasi Smart Campuss dan merancang perbaikan desain guna meningkatkan aspek pengalaman pengguna. Evaluasi dilakukan menggunakan metode system usability scale (SUS) yang dipadukan dengan pendekatan design thinking. Sampel penelitian terdiri dari 30 responden kuantitatif sesuai teori Laura Faulkner dan 5 responden kualitatif untuk wawancara mendalam mengacu pada rekomendasi Jakob Nielsen dengan partisipan mencakup mahasiswa aktif kelas reguler serta karyawan Unisbank. Hasil penelitian menunjukkan bahwa aplikasi Smart Campuss versi asli memperoleh skor SUS sebesar 60,75 dengan grade D yang mengindikasikan bahwa aplikasi belum memenuhi standar usability dan perlu dilakukan perancangan ulang. Setelah dilakukan perancangan ulang menggunakan pendekatan design thinking, skor meningkat sebesar 18,25 poin menjadi 79,00 dengan grade B. Temuan ini membuktikan bahwa desain ulang mampu secara signifikan meningkatkan tingkat usability sekaligus memperbaiki penerimaan pengguna terhadap aplikasi.

Basis data dianggap sebagai pangkalan data yang paling mendasar dalam sebuah sistem informasi. Seiring perkembangan jaman, jumlah data yang diolah oleh sebuah sistem informasi akan menjaadi sangat besar. Basis data saat ini tidak hanya tersimpan pada satu lokasi media penyimpanan, namun dapat tersimpan pada berbagai lokasi dan tempat penyimmpanan. Hal ini juga di dukung oleh perkembangan teknologi jaringan baik perangkat keras dan perangkat lunak yang mendukung. Model sistem basisdata terdistribusi sangat mendukung untuk pengolahan data yang tersimpan pada lokasi yang berbeda. Banyak implementasi sistem informasi yang mengunakan kopsep sistem basisdata terdistribusi. Penelitian ini bertujuan untuk melihat perkembangan dari implementasi sistem basisdata yang menggunakan teknologi sistem basisdata terdistribusi. Penelitian ini menggunakan metode sistematic literature review. Hasil yang diperoleh adalah bahwa konsep sistem basisdata terdistribusi saat ini masih digunakan untuk mendukung tata kelola sistem informasi yang mengashilkan informasi yang sesuai dengan tujuan pengguna. Sistem yang dibangun menggunakan metode-metode pengambangan pada konsep basisdata terdistribusi memiliki keunggulan dalam beberapa aspek pengembangnnya

This study aims to analyze the implementation of the debate technique in improving students’ speaking skills and to assess the outcomes after its application. Conducted in class XI A3 of SMAN 19 Tangerang Regency, the research involved 36 students and employed Classroom Action Research (CAR) through two cycles. Data was collected via observation, documentation, and speaking tests, and analyzed using both quantitative and qualitative methods. The population of this research is 180 students in the XI science classes, while for the samples, the researcher selected 36 students from XI A3 because this class is considered to be the most passive one compared to others . xxxxx The findings revealed that the debate technique was effective in enhancing students’ speaking performance, self-confidence, and classroom interaction. The pre-test score was 62 . These improved to 68.67 in the in cycle one. In the cycle 2, students exceeded the minimum passing score, achieving 76.89. The results indicate that debate is a beneficial and engaging technique for fostering speaking skills in an EFL context. It is recommended that teachers integrate debate activities into their instruction to encourage student participation, critical thinking, and oral communication. Yet, the improvement on the pronunciation needs more exploration for the next research.
