Abstract

Layanan pesan masyarakat secara online berupa teks yang perlu mendapatkan tanggapan sesegera mungkin oleh pihak terkait. Oleh karena itu dibutuhkan sistem klasifikasi teks dengan akurasi yang baik. Salah satunya adalah dengan metode Support Vector Machine (SVM) yang memiliki variasi kernel. Akan tetapi kelemahan SVM adalah untuk penentuan parameternya. Salah satu pendekatan dalam optimisasi penentuan parameter adalah menggunakan Algoritma Genetika (AG). Penelitian ini bertujuan melakukan optimisasi parameter pada SVM menggunakan AG pada kasus layanan pesan masyarakat pada Sambat Online Kota Malang. Jumlah sampel data diambil pada layanan tersebut sebanyak 200 pesan dengan tujuh kelas kategori yang dibagi menjadi data latih dan data uji yang bervariasi perbandingannya. Paremater yang dioptimasi pada masing-masing kernel antara lain kernel linear (C), polynomial (C, ????, derajat), RBF (C,????), dan sigmoid (C,????). Optimisasi dan pengujian dilakukan dengan variasi persentase rasio data latih dan data uji yaitu 20:80, 40:60, 60:40, 80:20. Pengujian dilakukan dengan menerapkan parameter hasil optimisasi dan mengukur tingkat akurasinya. Hasil pengujian terbaik diperoleh pada kernel linear dengan tingkat akurasi sebesar 85,37% pada rasio data latih terhadap data uji sebesar 80% : 20%. Hal ini menunjukkan bahwa kernel linear lebih sesuai dibandingkan kernel lainnya apabila digunakan pada kasus klasifikasi teks pada layanan Sambat Online.

Abstract

ABSTRACTThe internship program is an integral part of the Vocational School Higher Education curriculum.

In a pandemic situation that has recently lasted for approximately two years, the internship program for students within the company is also ongoing even though with different methods and methods, namely what is called WFH (Work From Home). For students, internships are not only an opportunity to learn practical work in the world of work, internships also mean an opportunity to learn about the culture of other people or companies. The internship program is an opportunity for students to learn more about how to adapt to other people's cultures or the existing company culture. With a qualitative approach, this paper tries to explore more deeply how the internship program is a good opportunity for students to be able to know or learn about cultural issues from other people, which include: work culture, time discipline, and other existing habits in a company.Keywords: Internship, Culture, Human Resource Management, Vocational.
