Judul: Aplikasi Tabel Select-dan-Ultimate dalam Penentuan Premi Asuransi
Abstrak: Mortality is one of the three demographic components, namely mortality, fertility, and migration. Life table can be constructed mathematically to give a description of mortality. Life table is also needed to determine insurance premiums. Being insured can reduce losses caused by accidents, because insurance is a product of planning for the future. In general, life table is constructed based on some health informations. But, certain selected health informations may result in different life table, which is called select-and-ultimate table. The purpose of this paper is to study and construct life table as well as select-and-ultimate table. Futhermore, select-and-ultimate table is applied to determine insurance premiums. The results of the analysis show that the select-and-ultimate table can reduce the premiums paid by insurance participants

Judul: Perbandingan Metode Interpolasi Abridged Life Table dan  Aplikasinya pada Data Kematian Indonesia
Abstrak: Salah satu cara untuk menyajikan data kematian suatu negara berupa jumlah penduduk yang meninggal dunia pada umur tertentu, peluang seseorang meninggal dunia sebelum mencapai umur tertentu dan angka harapan hidup seseorang umur tertentu adalah dengan life table atau tabel hayat. Tabel hayat digunakan pada bidang demografi dalam memprediksi jumlah penduduk di masa mendatang. Dalam bidang asuransi, tabel hayat digunakan untuk menentukan besar premi yang akan dibayar oleh pemegang asuransi. Selain itu, tabel hayat juga digunakan di bidang kesehatan dalam menentukan peluang seseorang dapat bertahan hidup dalam jangka waktu tertentu.

Judul: Production of Nanocellulose- Polyvinyl Alcohol- Alginate Based Filaments
Abstrak: Oil palm empty fruit bunches (OPEFBs) are solid waste that are produced from crude palm oil extraction. Generally, it contains around 41-46.5% of cellulose, 25.3-33.8% of hemicellulose, and 27.6-32.5% of lignin (Suriyani 2009). Nanocellulose (NC) was isolated from OPEFBs through several treatments, including delignification, bleaching, ultrafine grinding, and ultrasonication. The obtained nanocellulose was processed further into filaments by mixing with sodium alginate and polyvinyl alcohol (PVA). In this project, nanocellulose- PVA- alginate based filaments were produced by wet spinning method with CaCl2 as coagulant solvent. The effect of several formulations and CaCl2 concentration on the morphological, mechanical, and thermal properties of filaments were observed. The results showed that the increasing of NC concentration produced filaments that have better thermal properties and higher crystallinity, but the morphology of filament surface become rougher. The increasing of NC concentration up to 7% also increased the filament mechanical properties. Meanwhile, the increasing of CaCl2 concentration produced filaments that have better thermal properties, smoother surface, and higher crystallinity (up to 10% CaCl2), but with decreasing of mechanical properties (tensile strength) due to some cracks that occured on the surface of filaments with 13% of CaCl2.
