- In the organization of good service of efficient and efficient activities. The better the service will affect the level of satisfaction felt by the community. These efforts will increase higher. Enforcement of discipline makes work more effective and efficient. The research method used is descriptive quantitative by digging data using techniques, interviews and questionnaires. Test the instrument using Product Moment's expression and reliability test using Alpha Cronbach's. Hypothesis test consists of simple regression test and multiple regression test. The results showed that: (1) there was a positive relationship between Quality of Service to Satisfaction Society with rx1y = 0,594; r2x1y = 0.353; t count (8,196)> t table (1,979) at 5% significance level. (2) positive condition between Work Discipline to Satisfaction of Society with rx2y = 0,59; r2x2y = 0.359; t arithmetic (8.298)> t table (1.979) at a significance level of 5%. (3). Conditions and Discipline Against Satisfaction of Society with Ry(1,2) = (0,671); R2y (1,2) = (0,450) F value count (49,989)> F table (3,07) at 5% significance level. Keywords: Service Quality, Work Discipline, Public Satisfaction.

Penyakit tuberkulosis merupakan penyakit menular dan mematikan di dunia, bahkan World Health Organization (WHO) mencanangkan sebagai  penyakit kedaruratan dunia (global emergency). Banyak gejala  yang bisa terjadi pada  seseorang yang terjangkit tuberkulosis, dan  untuk menganalisa gejala tersebut bukan hal yang mudah, perlu dilakukan  tes dahak  pada penderita.  Selain itu,  dibutuhkan  juga  sebuah  metode  yang dapat  mempermudah  saat melakukan  analisa dan  menggali informasi pasien dari data rekam medik  yang tersedia. Pada penelitian ini, penulis akan menerapkan metode klasifikasi data mining, yaitu Algoritma C4.5 untuk mendiagnosa penyakit tuberculosis. Berdasarkan hasil pengukuran performa dari model tersebut dengan  menggunakan  metode pengujian Cross Validation, Confusion Matrix dan Kurva ROC, diketahui bahwa algoritma C4.5 memiliki tingkat akurasi sebesar 84,56% dan nilai area under the curva (AUC) sebesar 0,938. Hal ini menunjukkan bahwa model yang dihasilkan termasuk kategori klasifikasi  sangat baik karena memiliki nilai AUC antara 0.90-1.00.
