Abstract

MBKM (Merdeka Belajar – Kampus Merdeka) is a program provided by the Ministry of Education, Research, and Technology (Kemenristek) to improve the quality of education in Indonesia. One of the most popular MBKM programs is the MSIB Program (Certified Independent Study and Internship Program). Internship based on MBKM (Merdeka Belajar Kampus Merdeka) is an internship/work practice program that can be taken by students who have completed at least semester 5 of their studies. This program is a form of university collaboration with industry to provide independent learning. The purpose of MBKM is to hone hard skills and soft skills to suit the needs of the times and be ready to welcome the world of work. MSIB (Certified Independent Study and Internship), this program allows students to do internships at companies or take learning to increase their knowledge in the world of work. Independent Study Program is a non-degree learning program organized by organizations or industries that provide knowledge and skills with a high level of relevance in the world of work and business in the form of short courses, bootcamps, massive open online courses (MOOCs), and others, which are continued with collaborative activities with fellow participants or partner organization personnel in a project or case study. The following are the characteristics of Independent Study certified by Kampus Merdeka. For MSIB7 as a partner of MBKM Yayasan Decoding Indonesia, the MBKM team is entrusted as a means of certified learning assisted by DPP (Program Supervisor) whose participants are all lecturers throughout Indonesia who have been declared to have passed as DPP by Kampus Merdeka.

Abstract

This study examines the application of Python-based Google Colab in implementing tree theory through the Random Forest Classifier algorithm for income classification in data science, artificial intelligence, and machine learning professions. The research adopts an experimental quantitative approach using secondary data sourced from a global employment dataset. The methodological process includes data preprocessing, feature selection, class balancing, model training, and performance evaluation within the Google Colab environment. The results demonstrate that Random Forest effectively represents tree theory through ensemble decision structures capable of handling complex and heterogeneous data. Model evaluation indicates a satisfactory level of accuracy, confirming the classifier’s ability to generalize patterns across different income categories. Feature importance analysis reveals that job title, experience level, and company location play a significant role in determining income classification. These findings highlight the relevance of Random Forest as both a predictive and interpretative model, while emphasizing Google Colab’s effectiveness as a computational platform for machine learning experimentation. Overall, the study contributes to the practical understanding of tree-based algorithms and their application in analyzing labor market dynamics within the digital economy.

Abstract

Penelitian ini bertujuan untuk mengklasifikasikan sentimen ulasan pelanggan pada platform e-commerce (Shopee, Tokopedia, Bukalapak, dan Lazada) guna mengevaluasi tingkat kepuasan pengguna secara otomatis. Metode yang digunakan adalah algoritma Naive Bayes dengan pembobotan kata TF-IDF, yang diimplementasikan pada dataset sebanyak 40.000 ulasan dari Kaggle Dataset. Proses penelitian mencakup tahapan preprocessing yang terdiri dari cleaning, case folding, tokenizing, filtering, dan stemming. Hasil penelitian menunjukkan bahwa model pada algoritma Naive Bayes mampu mencapai tingkat akurasi sebesar 84,88%. Berdasarkan analisis distribusi sentimen, aplikasi Shopee memperoleh ulasan positif terbanyak (6.769 ulasan), sedangkan Bukalapak menerima ulasan negatif tertinggi (4.365 ulasan). Meskipun sangat efektif dalam membedakan sentimen positif dan negatif, model ini belum mampu mengidentifikasi sentimen netral, sehingga disarankan penggunaan teknik oversampling pada penelitian selanjutnya untuk menangani ketidak-seimbangan data.
