Abstract

Di era big data saat ini, peran teknik data mining sangatlah dibutuhkan terkait kebutuhan pengambilan keputusan yang akurat. Algoritma decision tree telah lazim diterapkan untuk menemukan pola klasifikasi karena mudah diinterpretasikan namun harus senantiasa dievaluasi tingkat performanya. Adaboost merupakan salah satu metode untuk meningkatkan performa algoritma decision tree. Eksperimen dilakukan pada 141 sampel perusahaan yang melantai di Bursa Efek Indonesia sektor konstruksi-infrastruktur, pertambangan-perminyakan, dan sektor perbankan pada periode 2019, dengan menerapkan teknik adaboost pada decision tree dengan parameter maximum depth dan confidence yang diuji dalam enam skenario berbeda berdasarkan informasi anti-korupsi pada pengungkapan laporan tahunan perusahaan. Hasil ekperimen decision tree untuk akurasi sebesar 69,5%, AUC-optimistis 0,826, dan AUC 0,756, sedangkan rerata hasil dari enam skenario decision tree versi  adaBoost untuk akurasi sebesar 71,16%, AUC-optimistis 0,8905, dan AUC 0,744, sehingga dapat disimpulkan bahwa pengklasifikasian atas prediksi klasifikasi dengan metode adaBoost layak diterapkan sebagai upaya alternatif untuk meningkatkan tingkat performa yang lebih baik.

Abstract

International trade has now become an important activity of a country in boosting its economy. In particular, in the current era of globalization, every country in the world is required to be able to compete for markets in the world. Therefore, economic improvement through the growth of the Micro, Small and Medium Enterprises (MSMEs) sector is one of the alternative solutions in the midst of today's competitive market competition. MSMEs are required to be able to survive and compete with their people's economic pattern in the midst of competitive competition with various large multinational companies. What's more, after the Covid-19 pandemic which had a significant impact on the world economy, many changes were made as an adaptation to recover the economy and rise to compete in an increasingly competitive trade. This economic adaptation also includes how MSMEs and cooperatives run their business units in an effort to survive financially. This Community Service activity uses the method of delivering material from various sources, activists of exportimport activities and academics. The survey method was also carried out to see the knowledge of young MSMEs in Bandar Lampyng related to international business and export-import activities. The external plan for this activity is publication in the LPPM service journal, University of Lampung.
