Abstract

Dalam penentuan besaran nilai premi dipengaruhi oleh tingkat suku bunga. Besaran nilai suku bunga ditentukan dengan menggunakan model suku bunga Vasicek dan model suku bunga CIR. Riset ini bertujuan untuk penentuan besaran nilai suku bunga, besaran nilai premi, dan perbandingan besaran nilai premi dari model suku bunga Vasicek dan model suku bunga CIR. Dalam penelitian ini akan dilakukan perhitungan nilai premi asuransi jiwa berjangka 5 tahun dengan menggunakan nilai suku bunga dengan kasus pertama pembayaran cicilan premi saat besaran konstan tapi berbeda untuk dua periode dan kasus kedua cicilan premi saat besaran meningkat secara linear ketika uang pertanggungan dibayarkan di akhir interval 1/12 tahun. Hasil perhitungan premi asuransi jiwa berjangka yang dihasilkan dari penerapan model Vasicek dan model CIR bernilai positif dan tidak ada perbedaan yang signifikan.

Abstract

The continuous mutation of COVID-19 generates new virus variants with nearly identical symptoms, such as sneezing, runny nose, sore throat, cough, fever, loss of taste and smell, and shortness of breath. Since the emergence of this virus in Indonesia, there still needs to be more research on the symptoms caused by the different COVID-19 variants, leaving the public with minimal information that may result in inappropriate early treatment, inefficient costs, and insufficient recovery time. This study aimed to classify COVID-19 patient data into two clusters based on the severity of the symptoms experienced by patients: the confirmed cluster and the unconfirmed cluster. Using Fuzzy C-Means, patient data will be clustered into two confirmed and unconfirmed clusters of covid 19 disease as the initial step in the research phase. The results of this study are anticipated to provide information on variations in the severity of symptoms among infected patients, thereby enhancing the precision of early diagnosis and treatment. The resulting clustering model is based on data collection and processing outcomes using Python and the Fuzzy C-Means algorithm, which is based on experimentation. Keywords: Cluster, COVID-19, Fuzzy C-Means.

Based on the research gap, this study analyzes the herding behavior of consumers as borrowers. It analyzes consumers’ perspectives as borrowers on technological innovation in peer-to-peer lending in making decisions to fulfill basic physiological needs. The study relays to descriptive qualitative research. It analyzes the social situation that leads to phenomenology. Purposive sampling and snowball sampling were used in this study. There were 31 participants involved in this study that belonged to individuals who have made online loans with the peer-to-peer lending system. A qualitative open-ended question questionnaire was used to collect the data. The finding of this study shows that as many as 70.97% of the 31 respondents use fintech lending applications from recommendations of a friend or relative. In the current phenomenon, consumers imitate people who previously used fintech lending applications. Therefore, the result is in line with the concept of Herding Behavior that respondents select to use the fintech lending application because of an invitation and recommendation from a friend or relative. In addition, most respondents aged 20-30 years who are unmarried use fintech lending applications to fulfill lifestyle needs, while respondents aged 20-40 who are married use fintech lending applications to fulfill basic and business needs.
