Dalam penyelesaian jenjang strata atau diploma, mahasiswa harus melewati tahap akhir yaitu penyelesaian tugas akhir. Dengan banyaknya mahasiswa yang mengajukan tugas akhir, proses pengarsipan dokumen tugas akhir berdasarkan topik membutuhkan klasifikasi yang dilakukan oleh Perpustakaan Universitas. Klasifikasi topik tugas akhir secara manual dapat menghambat proses lain yang harus diselesaikan oleh staff perpustakaan. Oleh karena itu, diperlukan adanya klasifikasi dokumen tugas akhir secara otomatis, cepat dan akurat untuk klasifikasi topik tugas akhir. Penelitian ini memanfaatkan pembobotan TF-IDF serta pendekatan algoritma Multiclass Support Vector Machine. Pembobotan TF-IDF ini merupakan formula yang merepresentasikan signifikansi suatu kata (term) dalam sebuah dokumen dan korpus. Pemobotan yang sudah dihitung dengan TF-IDF, kemudian menghitung hasil prediksi bobot menggunakan Support Vector Machine. Dikarenakan Support Vector Machine hanya bisa menentukan 2 kelas, diperlukannya metode one against rest dalam algoritma support vector machine untuk menentukan lebih dari 2 kelas. Penelitian ini bertujuan untuk membuat sistem yang dapat mengelompokkan topik tugas akhir secara otomatis, cepat dan akurat untuk pengarsipan tugas akhir di Perpustakaan. Hasil dari perhitungan pengujian dengan data latih dan data uji menggunakan pembobotan TF-IDF dan algoritma multiclass support vector machine menghasilkan persentase sebesar 90.71%.

Measurement of electrical energy consumption is very important for everyday life as well as in the industrial sector. As it is known that this amount of energy is the basis for calculating the cost of using electrical energy in kWh units, so that later it will appear in the payment bill. However, this important information is very impractical and inconvenient if to see the amount of the bill, we have to check directly on the KWH meter that is mounted on the wall, and this becomes impractical with a large number of electricity meters. Therefore an IoT-based KWH measurement system is designed that allows monitoring of KWH quantities to be carried out mobile or even remotely via the internet network in a dashboard, making it more practical and efficient. The main components consist of the PZEM-004T module which functions as a measure of AC current and AC voltage used by the load, while the ESP32 module processes the results of measurements made by PZEM-004T and then connects to a computer so that the measured values can appear by PZEM- 004T. The results obtained show that the accuracy of the current and load voltage measurement results, when compared with the results of manual measurements using a digital voltmeter and ammeter, shows a difference of below one percent, meaning that the results of remote measurements with the PZEM-004T provide a good accuracy value.

Vuxia Beaute Cafe is a business in the beauty cafe industry established since September 2021. They always strive to ensure customer satisfaction by serving high-quality beverages. However, in running their business, they face challenges in determining the right syrup brand for their drinks. This is crucial because the syrup brand can influence the quality of the beverages they serve. Currently, the issue they are facing is the difficulty in finding a syrup brand that aligns with the customers' preferences and the lack of an effective procedure to objectively evaluate syrup brands. Currently, the evaluation of syrup brands is done subjectively based on the assessments of the cafe owner and head barista, making it challenging to determine the best syrup brand objectively. To address this problem, Vuxia Beaute Cafe needs a decision support system to assist in determining the best syrup brand based on the predefined criteria. In this research, the criteria used are taste, aroma, price, expiration date, and texture. The Simple Multi-Attribute Rating Technique (SMART) method was chosen because it is faster, simpler, and more effective in solving the problem. The data processing results indicate that the best syrup brand for Vuxia Beaute Cafe is Delifru with a score of 0.79, chosen based on the predefined criteria.
