Abstract

Proses identifikasi merupakan bidang teknologi yang sedang menjadi perhatian untuk dikembangkan. Salah satu cara dalam proses identifikasi seseorang antara lain dengan menggunakan pengenalan suara. Penelitian ini bertujuan untuk mrngukur kinerja MFCC sebagai ekstraksi ciri sinyal suara dengan Support Vector Machine (SVM) sebagai algoritma klasifikasi. Sampel suara yang digunakan adalah bacaan dari AL-Qur’an yang terdiri dari 4 surah yaitu, Surah Al-Baqarah ayat 255 dan 256, Surah At-Thalaq ayat 2 dan 3, Surah At-Thariq ayat 1-3, dan Surah Al-Ghasyiyah ayat 17-19. Hasil transformasi sinyal suara menggunakan ekstraksi MFCC dan unjuk kerja SVM pada pengujian masing-masing surah menghasilkan nilai true yang berbeda. Nilai akurasi tertinggi diperoleh pada surah At-Thariq ayat 1,2, dan 3 sebesar 70%. Nilai akurasi terendah diperoleh pada surah Al-Ghasyiyah ayat 17, 18, dan 19 sebesar 56%. Hal ini menunjukkan bahwa pengukuran kinerja ekstraksi MFCC sebagai ekstraksi sinyal suara dengan SVM sebagai algoritma klasifikasi dapat dijadikan alternatif dalam pendekatan pengenalan suara.

Abstract

This research aims to find out how to design and build an employee e-recruitment information system using the simple additive weighting method. There are three types of data collection methods in this research: observation, interviews, and literature study. The system development method used in this research is the OOAD (Object-Oriented Analysis and Design) method with the rapid application development model, while the tools used in object modeling are UML (Unified Modeling Language). From the discussion that has been described, the following conclusions can be drawn: This e-recruitment information system was designed and built using the RAD system development method and the SAW method for calculations in decision-making, using the PHP and MySQL programming languages as the database, and tested with black box testing. By using the e-recruitment information system to recruit employees, the HR and general divisions have a reference for selecting which prospective employees most closely match the predetermined criteria. This e-recruitment information system can reduce the possibility of human error occurring during the selection process, and with the value of each applicant calculated in the system, it will become a reference for HR staff in selecting employees more objectively. The administrative selection process, which takes one month, can be reduced to a maximum of seven working days. With the e-recruitment information system, selection results that were previously reported via message can now be seen directly in each applicant's account at a predetermined time.

Abstract

The selection of partners at the Central Statistics Agency of Central Aceh Regency faces challenges because manual selection methods are considered inefficient and inaccurate. Therefore, this study aims to improve the accuracy and efficiency of the selection process by applying the Promethee (Preference Ranking Organization Method for Enrichment Evaluations) method. This method is used as a multi-criteria decision-making technique and is implemented using the Python programming language for automatic and real-time data processing. The data used comes from the 2024 partner recruitment process at the Central Statistics Agency of Central Aceh Regency, consisting of candidates who have met the administrative requirements. The validity of the promethee method is tested through the calculation of an error percentage that reaches 10%, demonstrating the method's ability to filter partners according to the established criteria. In conclusion, the application of the promethee method has been proven to improve the efficiency and accuracy of the partner selection process, where the Python-based system developed can reduce the time and effort required in decision-making while producing more valid and reliable partner recommendations.

Abstract

This study aims to determine the nutritional status of toddlers in the Peulimbang sub-district using a clustering method that can group toddlers based on their dietary indicators, such as gender (jk), age (u), height (tb), weight (bb), and upper arm circumference (Lila). By using data analysis techniques such as K-Means clustering, this study successfully identified several groups of toddlers with different nutritional statuses, ranging from malnutrition to good nutrition to obesity nutritional status. The data for this study were taken directly from the Peulimbang Health Center, and as many as 765 toddler data were collected from 16 villages in the Peulimbang area. The programming language used in this study is PHP, which functions in web development and is often used to process data sent via web formula, interact with databases, and manage user sessions. Based on the results of clustering with the K-Means method using Euclidean Distance as a measurement between points, toddler data has been grouped into three Clusters, namely C1, C2, and C3. Cluster C1 covers 22.81% of 147 malnourished toddlers, C2 covers 48% of 323 well-nourished toddlers, and C3 covers 29.19% of 205 obese toddlers. Based on the clustering results, improving nutrition education programs for parents is essential, especially in areas with poor or lacking nutritional status. This program can include counseling on the importance of balanced nutrition, nutritious cooking methods, and choosing the right Food for toddlers. Thus, this study is expected to contribute to improving toddlers' nutritional status and overall public health in the Peulimbang District area.
