Abstract

Pneumonia is a lung infection that causes inflammation in the air sacs within the lungs. This disease is caused by microorganisms such as bacteria, viruses, fungi, or even inhaled substances. This study aims to identify significant factors influencing the incidence of pneumonia in children under five years old in North Sumatra Province in 2022. In this case, the dependent variable has an excessive number of zero values (excess Zero), leading to overdispersion. By using the Zero Inflated Negative Binomial (ZINB) regression method, significant factors affecting the incidence of pneumonia in children under five years old in North Sumatra Province were identified. The study found that the variable of the number of low birth weight babies (BBLR) (X5) significantly influences the incidence of the disease in North Sumatra Province in 2022. It can be seen from the significant variables affecting the occurrence of pneumonia in children under five, which are 0.0406% (X1), 0.00952% (X2), 0.006506% (X3), and 2.122% (X4).

Abstract

Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang memengaruhi pemilihan peminatan mahasiswa pada Program Studi Matematika di Universitas Islam Negeri Sumatera Utara (UINSU). Terdapat dua peminatan yang ditawarkan, yaitu Statistika dan Operasi Riset. Data diperoleh dari 84 mahasiswa yang terbagi dalam dua kelompok peminatan, dan dianalisis menggunakan metode analisis diskriminan. Hasil analisis menunjukkan bahwa variabel minat dan bakat serta peluang kerja memiliki pengaruh signifikan terhadap keputusan peminatan, sedangkan lingkungan sosial tidak memberikan pengaruh yang berarti. Fungsi diskriminan yang dibentuk mampu mengklasifikasikan peminatan mahasiswa dengan tingkat akurasi sebesar 76,2%. Temuan ini menekankan pentingnya pengenalan minat pribadi dan prospek karier dalam proses bimbingan akademik mahasiswa.
