Abstract

Financial Distress merupakan kondisi kesulitan keuangan perusahaan yang menyebabkan perusahaan tidak dapat memenuhi kewajibannya untuk menjalankan bisnis. Berdasarkan beberapa penelitian sebelumnya analisis financial distress terhadap suatu sektor bisnis dapat menggunakan model Cox-Hazard Regression dengan menggunakan variabel EPS sebagai indikator terjadinya financial distress pada perusahaan dalam suatu sektor bisnis. Penelitian ini bertujuan untuk mengetahui peluang survive 19 perusahaan sektor kesehatan di Indonesia berdasarkan perusahaan yang terdaftar di Bursa Efek Indonesia dan mengetahui apakah rasio keuangan Return on Equity, Debt on Equity Ratio, dan besarnya Sales terhadap terjadinya financial distress pada perusahaan sektor kesehatan dengan menggunakan Metode Cox-Hazard Regression. Data diperoleh dari laporan keuangan perusahaan-perusahaan sektor kesehatan yang terdaftar di Bursa Efek Indonesia pada tahun 2019-2023. Berdasarkan hasil analisis survival diperoleh hasil bahwa peluang survive dari financial distress perusahaan cenderung tinggi meskipun dilanda pandemi COVID-19. Namun, peluang survive perusahaan dari financial distress mengalami penurunan yang berarti pada akhir tahun 2022 hingga tahun 2023. Variabel independen Return on Equity, Debt on Equity Ratio dan jumlah Sales secara simultan berpengaruh secara berarti terhadap terjadinya financial distress perusahaan kesehatan di Indonesia yang terdaftar di Bursa Efek Indonesia tahun 2019-2023. Secara parsial, variabel independen Return on Equity dan Debt on Equity Ratio memberikan pengaruh yang berarti terhadap terjadinya financial distress pada perusahaan kesehatan di Indonesia yang terdaftar di Bursa Efek Indonesia tahun 2019-2023 sedangkan total sales tidak memberikan pengaruh yang berarti.

Abstract

Stunting is a disorder in children caused by chronic nutritional problems. Stunting is usually characterized by a child’s failure to grow and develop optimally.

The causes of stunting required scientific study to help the government understand the scientific factors that causing stunting. Therefore, this study aims to analyze the factors causing stunting the children in the Tangerang regency. The data analysis method in this study use the Seemingly Unrelated Regression (SUR), which is integrated with a machine learning, namely Random Forest. The data used in this study were obtained from primary data through questionnaires. The subjects of this study were parents of stunting and non-stunting children who were at “Posyandu” under of “Kelapa dua” and “Binong” health centers. Sampling method in this study is purposive-random sampling. The results of the data analysis showed that the five variables from the factors measured had the most significant influence, namely nutritional, socio-economi, and pregnancy and childbirth history factors. Five variables that influence children stunting are animal protein, which has the highest probability of 87.5% when the children consumes protein once or twice a week. The children consume vitamin A twice has a 97% probability. The source of income for the parents, whether from the private or self-employment, has a probability of over 90%. Furthermore, the consumption of iron-boosting tablets by mother during pregnancy and the amount of income from the parents have a probability of 84%.
