Abstract

Tuberculosis (TBC) adalah penyakit menular disebabkan oleh bakteri Mycobacterium Tuberculosis yang menyebar melalui udara yang terhirup ketika individu yang terinfeksi TBC batuk atau bersin. Kasus TBC di Jawa Timur menunjukkan peningkatan yang signifikan pada periode 2017 hingga 2024. Peningkatan ini terjadi tidak hanya antarwaktu tetapi juga antarwilayah kabupaten/kota yang mengindikasi adanya autokorelasi spasial antardaerah yang berdekatan. Penelitian ini bertujuan untuk memetakan kasus TBC di Jawa Timur dengan analisis regresi spasial, yang mencakup Spatial Autoregressive Model (SAR), Spatial Error Model (SEM), dan Spatial Autoregressive Moving Average (SARMA), dengan penggunaan pembobot spasial K-Nearest Neighbors (KNN) k=1,2,..,10. Model terbaik dipilih berdasarkan AIC terkecil. Data yang digunakan pada penelitian ini bersumber dari BPS tahun 2024. Selain itu, variabel yang digunakan meliputi faktor penyebab TBC dari aspek ekonomi, lingkungan, dan kesehatan. Model terbaik yang diperoleh pada penelitian ini adalah Spatial Autoregressive Moving Average (SARMA) dengan pembobot KNN k=8 dan memiliki nilai AIC sebesar 607,8. Variabel yang berpengaruh signifikan adalah kepadatan penduduk, jumlah puskesmas, persentase rumah tangga yang memiliki air minum layak, tingkat kegemaran membaca, dan rata-rata gaji bersih sebulan buruh/karyawan menurut lapangan pekerjaan (rupiah). Penelitian lanjutan dapat dilakukan dengan metode berbasis pola spatio-temporal seperti regresi panel.
