Pemanfaatan Klasterisasi K-Means untuk Pengelompokan Berdasarkan Indikator Ekonomi, Digitalisasi, dan Produksi Komoditas
Bibliographic record
Abstract
Penelitian ini bertujuan untuk memanfaatkan algoritma K-Means Clustering dalam mengelompokkan entitas berdasarkan berbagai indikator seperti dampak krisis ekonomi, kinerja perusahaan, adopsi digital, dan produksi komoditas. Data yang digunakan berasal dari sumber sekunder, termasuk dataset krisis ekonomi global (1970-2017), indikator kinerja perusahaan, persentase pengguna internet di ASEAN (2010), serta produksi komoditas perkebunan di Gunungkidul (2019). Metode penelitian meliputi tahapan preprocessing data (seleksi fitur, penghapusan missing values, dan normalisasi), penentuan jumlah klaster optimal menggunakan Elbow Method, dan evaluasi kualitas klaster dengan Silhouette Score. Hasil penelitian menunjukkan bahwa K-Means mampu mengelompokkan entitas dengan efektif, seperti membagi negara berdasarkan tingkat keparahan krisis ekonomi, perusahaan berdasarkan kinerja, negara ASEAN berdasarkan adopsi digital, serta kecamatan di Gunungkidul berdasarkan produksi komoditas. Temuan ini memberikan implikasi praktis bagi pengambilan kebijakan dan analisis lanjutan di berbagai sektor.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
