Judul: Penentuan Karakteristik Termofisik Bawang Merah (Allium cepa var.ascalonicum)
Abstrak: Information about thermo-physical properties of red onion are needed to know to optimize post-harvest treatment of onions both cooling and drying, as well as to optimize the use of energy during the post-harvest process. The study was to determine the thermo-physical properties of red onion (leaves and tubers) which consist of water content, thermal diffusivity, thermal conductivity, density, and specific heat as well as to obtain a mathematical equation model of the water content towards the thermo-physical properties of red onion. Drying leaves and onion tubers for 6 days obtained in specific heat values, thermal conductivity and density which were proportional to the decrease in the material water content, especially on the dehydration process of red onion leaves. Red onion thermal diffusivity was determined using a numerical method of cooling temperature data of onion tubers which produce data thermal diffusivity 1.433 x 10-8 m2/s with a mean accuracy average of 93.37%.

Abstrak: In storing of shallot seedbulbs, the damage because porous, disease, rooting and sprouting are often occur. The objective of this study was to determine the optimum temperature and packaging in order to maintain the qualities of shallot seedbulbs during the storing time. In this study, the packaging used is plastic net and polyethylene, stored at 10°C, 15°C, and room temperature. Parameters measured were weight loss, moisture content, hardness, damage, and sprouting. Room temperature could withstand the increasing of weight lost from week 2 to week 8 and temperature treatment could not withstand the decreasing of moisture content and hardness during the storing time. Storing at room temperature could withstand sprouting and damage of seedbulbs during the storing time. Plastic net packaging could withstand the increasing of weight loss at week 1 and week 2. Packaging treatment could not withstand the decreasing moisture content and hardness during the storing time. Polyethylene packaging could reduce damage during the storing time. Plastic net and polyethylene packaging could reduce sprouting during the storing time. Storing at room temperature with polyethylene packaging could reduce damage by 11.97% and sprouting by 0.004% during the storing time

Judul: Penetapan Harga Jaminan Polis Asuransi Jiwa dengan Premi  Tahunan dan Opsi Surrender
Abstrak: Asuransi jiwa memberikan perlindungan pada tertanggung (pemegang polis) jika mengalami risiko finansial, dengan suatu perjanjian tertanggung harus membayar premi. Premi yang sudah terkumpul pada perusahaan asuransi dapat diinvestasikan, yang salah satu tempatnya adalah di pasar bursa. Perusahaan asuransi menawarkan suatu kontrak kepada pemegang polis yang disebut dengan kontrak partisipasi. Pada kontrak partisipasi risiko finansial dan keuntungan dibagi dengan pemegang polis dan biasanya keuntungan tersebut dimasukkan ke dalam cadangan polis pada tiap akhir tahun kontrak. Hal ini berarti secara tidak langsung perusahaan asuransi menyatakan penambahan pertanggungan, sehingga mengakibatkan perubahan benefit yang diterima oleh pemegang polis. Pada kontrak partisipasi ini, pemegang polis diberikan hak untuk mengakhiri kontrak (opsi surrender). Pada kontrak partisipasi asuransi jiwa endowmen terdapat opsi bonus (bonus option) yang penghitungan besar preminya dengan pendekatan tipe Eropa dan opsi surrender (surrender option) dengan tipe Amerika.
