Abstract

In this paper, we conduct research by compiling an abridged life table using the graduation method based on real data obtained at Gegelang Village, West Lombok. The graduation methods used in this study included quadratic spline and Heligman-Pollard. Based on the results, a special case of A was chosen as a method used to make a rough life table before graduation. After the graduation process, it was found that the Heligman-Pollard method was the most suitable. This is based on the chart produced using this method, which is monotonous in nature and does not fluctuate like other graduation methods. In addition, the life expectancy obtained at 65.72 years is close to West Lombok's life expectancy based on 2015.

Abstract

This research aims to reconstruct a life table based on real data obtained in Gegelang Village, West Lombok. The data used in this research is the population in 2016, the death rate in 2014-2018 and the birth rate in 2014-2018. The first step taken was to compile a rough life table using the partial data situation and full data situation methods. Both methods are included in the maximum likelihood method. After carrying out calculations, different life expectancy figures are obtained. The respective calculation results were 62.21 years for the partial data situation method and 73.07 years for the full data situation method. Next, a graduation is carried out using the natural cubic spline method on the life table obtained from a rough life table model calculation. The graphic model produced by the rough life table is fluctuating so it is necessary to graduate using the natural cubic spline method to obtain a monotonically decreasing graph. The life table model chosen for graduation is a life table whose life expectancy is close to the life expectancy of West Lombok Regency in 2015, namely 65.1 years. After graduation, the new life expectancy was found to be 66.92 years.

Abstract

Life tables are a fundamental tool in actuarial mathematics, providing a systematic framework for mortality analysis and survival probability calculations. This study aims to provide a comprehensive overview of life table construction methodology, its applications in the insurance and pension industries, and recent developments in this field. Using a systematic literature review approach, this study analyzes 20 relevant publications from 2014–2024, with a particular focus on the 10 most recent publications from the past 5 years. The results show that life tables have undergone significant evolution in their construction methodology, particularly with the integration of machine learning and big data analysis techniques. Applications of life tables have also expanded, encompassing not only life insurance premium calculations and actuarial valuations, but also longevity risk analysis, retirement planning, and public health policy. Recent developments indicate an increasing trend in the use of stochastic models, dynamic mortality projections, and adaptation to global demographic changes. This study contributes to a holistic understanding of the role of life tables in modern actuarial mathematics and provides insights into future development directions.

Abstract

Pelayanan kesehatan berkualitas dan memuaskan merupakan elemen vital dalam aspek perawatan pasien. Rumah Sakit bertanggung jawab menyediakan layanan yang aman, efektif, dan sesuai kebutuhan pasien. Oleh karena itu, survei kepuasan pasien menjadi relevan dalam konteks rumah sakit. Namun, studi ini mengungkapkan kekurangan dalam layanan survei kepuasan di Website Rumah Sakit Umum Daerah (RSUD) Kota Mataram. Walaupun ada aplikasi mobile SiPasti RSUD Kota Mataram yang memfasilitasi pengaduan pengguna, keterbatasan ini menghambat pengguna yang ingin memberikan tanggapan atau saran secara online. Terutama, ketersediaan aplikasi hanya pada platform Android menjadi kendala. Banyak pengguna mengeluhkan hal ini dan menyatakan perlunya peningkatan layanan survei di website rumah sakit. Sebagai solusi, disarankan agar Rumah Sakit Umum Daerah Kota Mataram mengembangkan Halaman Survei Kepuasan Pengguna Berbasis Web untuk mengatasi kendala tersebut. Dari pengabdian yang telah dilakukan, dihasilkanlah sebuah web survei yang telah menjadi prototype bagi pihak rumah sakit untuk mengembangkan halaman survei dari RSUD Kota Mataram. Dengan adanya sistem ini, pengguna dapat memberikan masukan dan saran terhadap pihak rumah sakit secara lebih personal yang akan dapat meningkatkan pelayanan di RSUD Kota Mataram.
