Judul: Pendugaan Life Table Multiregional untuk Empat Kategori Wilayah di Indonesia Berdasarkan Sensus Penduduk 2010
Abstrak: Karya ilmiah ini membahas tentang penyusunan life table multiregional Indonesia yang dibagi dalam empat wilayah yaitu wilayah 1 (provinsi Jawa Barat), wilayah 2 (provinsi DKI Jakarta dan Jawa Tengah), wilayah 3 (provinsi Sumatera Utara, Jawa Timur, dan Banten), dan wilayah 4 (provinsi lainnya). Dalam penyusunan life table multiregional, dibutuhkan nilai mortalitas yang diperoleh dari perhitungan life table uniregional dan arus migrasi keluar yang nilainya diperoleh dengan menggunakan model arus migrasi Jawa Bali dan Luar Jawa Bali. Berdasarkan hasil analisis demografi uniregional maupun multiregional menunjukkan penduduk di wilayah 2 (provinsi DKI Jakarta dan Jawa Tengah) memiliki angka harapan hidup tertinggi dibandingkan wilayah lainnya.

Judul: Pendugaan Life Table Penduduk Wanita Indonesia Berdasarkan Data Sensus
Abstrak: Indonesian life tables are obtained indirectly using Coale-Demeny life table, because of the difficulty of getting data required especially the data of population mortalities. One of direct data set to be considered is the number of survival to age . In life insurance, life tables are used to determine the amount of premium to be paid by the insurance holder. This paper is intended to estimate a life table based on census data. This is done using surviving probability method, which will be done in three different approaches, i. e. smoothed Coale-Demeny life table, smoothed logit system, and the third method is the projection and accumulation approach. The resulting life tables are then compared to the life tables of BPS and concluded that both are similar.

Abstrak: Leather tanning using oil as the tanning agent has disadvantages, such as the time of oxidation which is takes a long time in about 9 days. Using sodium percarbonate as oxidizing agent in the tanning process, known to shorten the time into two days, eventhough, the high cost of sodium percarbonate was being obstacle in its use. Other oxidizing agents such as hydrogen peroxide and sodium hypochlorite may have the same function with sodium percarbonate, i.e. acceleration of the oxidation process. The objectives of this research were to investigate the influence of the oxidizing agents and their concentrations on the quality of chamois leather and to determine the best combination of type and concentration of oxidizing agents in the production process of chamois leather. The main research consisted of leather tanning using rubber seed oil, oxidation in drum with three types and concentrations of the oxidizing agents, measurements of physical, chemical and organoleptic properties of chamois leather. The results showed that the three types of the oxidizing agent could be used to accelerate the oxidation process in the manufacture of chamois leather. The type of oxidizing agent gave significant effect on shrinkage temperature, ash content, colour and odour of leather, while the oxidizing agent concentration significantly affected the colour and odour of chamois leather. The treatment of experiment selected based on the quality of leather was sodium hypochlorite with the concentration of 2%. Tanning by using this treatment produced chamois leather with the properties as follows: shrinkage temperature of 75.2oC, tensile strength of 30.5 N/mm2, elongation at break of 134.3%, tear strength of 86.2 N/mm, water absorption of 265% (2 hours) and 286% (24 hours), pH 6.56, oil content of 8.71%, ash content of 1.12%, softness of 8-9, colour of 7-8 and odour
