Abstract

One of the aims of the tracer study is to obtain information about the early careers of alumni, so that some of the questions on the questionnaire need to be explored further. The question items discussed were length of study, length of time to get the first job, field of work, total income, alumni's perception of the closeness of the field of study to work, and the suitability of education level on the job, and taking into account gender and average level of competence. The purpose of this study was to analyze the relationship between these variables in the 2020 tracer study data from alumni of 4 science fields at FMIPA and FKIP Unsri. The method used is descriptive statistics and simple correspondence analysis. Almost all respondents from both faculties stated that the suitability of the level of education with the field of work was at the same level. In respondents from both faculties, there is a significant relationship between respondents' perceptions of the closeness of their field of study with their field of work. The average total income of FMIPA respondents is higher than that of FKIP respondents. FMIPA respondents who stated that their field of study was "less close" to their field of work had a high total income and their field of work was self-employed. FKIP respondents who had a length of time to get their first job of less than 3 months (even before graduating) tended to have a length of study of 4 years and their field of work was in government/BUMN and private institutions. The respondents have the perception that their field of study are "very close" to their field of work.Keywords: tracer study, field of work, first job, Unsri alumni, correspondence analysis

Abstract

Salah satu tujuan tracer study atau penelusuran alumni adalah untuk mengevaluasi daya saing lulusan dan memperoleh informasi evaluasi relevansi dari perguruan tinggi. Penelitian ini membahas hubungan antara persepi lulusan (alumni) pada tingkat kompetensi yang dikuasai dengan tingkat kompetensi yang dibutuhkan dunia kerja, serta mengeksplorasi kecendrungan apakah ada perbedaan persepsi alumni pada dua tingkat kompetensi dari setiap item kompetensi yang ada di kuesioner tracer study. Selain itu, tujuan dari penelitian ini adalah menganalisis hubungan antara gender dengan masing-masing tingkat kompetensi yang dikuasai dan kompetensi yang dibutuhkan dunia kerja. Data yang digunakan adalah hasil jawaban kuesioner tracer study Unsri tahun 2020 pada pertanyaan 29 item kompetensi dari 3.850 responden. Responden merupakan 65,82% dari semua lulusan S1 Unsri tahun 2018.  Dengan menggunakan korelasi Spearman, uji Wilcoxon, deskrispsi histogram, uji c2 pada hasil analisis korespondensi, maka didapat bahwa ada 8 item kompetensi yang perlu ditingkatkan supaya sesuai dengan tingkat kompetensi yang dibutuhkan bidang pekerjaan. Grafik yang diperoleh merepresentasikan bahwa mayoritas responden mempunyai tingkat kategori kompetensi yang dikuasai dan yang dibutuhkan pekerjaan yang sama dan terletak pada kuadran yang sama, terutama pada tingkat 3 (“Sedang”) dan 4 (“Tinggi”). Menurut gender, item tingkat kompetensi yang dibutuhkan bidang pekerjaan yang perlu ditingkatkan bagi alumni laki-laki adalah Bahasa Inggris, Manajemen waktu, Kemampuan adaptasi, dan Kepemimpinan. Sedangkan bagi alumni perempuan, tingkat kompetensi yang dikuasai yang perlu ditingkatkan adalah pengetahuan di luar bidang ilmu dan kepemimpinan.

Abstract

This study aims to explore patterns of student academic performance specifically about questions on exponents and roots using K-Means clustering and Principal Component Analysis (PCA). An exploratory quantitative method was employed, using data from a final mathematics examination involving 100 ninth-grade students and 10 questions. Twenty students who gave no answers were excluded from the analysis, leaving 80 students for the clustering process. The function of K- means in this research were defined students on the same group with same categorize with similarities responses. PCA was used for dimensionality and visualize for reduce data distribution groups that found. The analysis revealed two distinct groups where 75 students in the primary group scored a mean of 7.36 while 23 students in the secondary group scored a mean of 3.12. The highest silhouette score from these two different groups is 0,3128 that shows different significant patterns that seen. PCA results showed that primary and secondary principal components accounted for 42.70% and 14.89% of the variance with a cumulative explained variance of 57.58%. K-Means grouping effectively shows variations on these findings based on students’ responses with exponents and roots question. However, the diverse for the result between grouping that was written down, some overlap shows that the patterns are not entirely separate. These clustering results can serve as a basis for more detailed diagnostic investigations into how students respond to mathematical problem-solving.
