Judul: Time and Temperature Effects of Ultrasound Treatments on the Resistant Starch Content of Canna edulis Ker
Abstrak: Ultrasonication was applied to Ganyong (Canna edulis Ker) starch for three treatment of times (15, 30, and 45 minutes) at controlled temperature (30⁰, 45⁰, and 60⁰C). Ganyong as a local indigenous plant was chosen as the material in this study because it has big potential to produce resistant starch from its high content of amylose compared to other tuber’s starch, such as cassava, sweet potato, yam and arrowroot. Ultrasonication at 60⁰C and 45 minute was chosen as best treatment combination in this study due to the highest yield of resistant starch produced. Native canna starch was observed to have 1.45±0.24 % of resistant starch, however the number significantly increased to 48.19 ± 0.84% of resistant starch after modification (p<0.05). Further physicochemical changes of native and modified starch were observed. The results showed that there were no significant changes in the proximate analysis profiles before and after treatment. However, the ultrasonication significantly influence the pasting profiles (p<0.05) which was also expected due to the increase of starch granule size range from 30-160 μm to 45-179 μm after modification. The morphological changes were clearly observed by SEM and PLM, which showed swollen granule with rougher surface and fissures after modification. Thermal analysis using DSC did not significantly influenced the gelatinization temperature of the granule starch, however the increase of enthalpy (ΔH) occured from 2.99 to 10.86 J/kg. This result indicated the increase of resistant starch within canna starch granule.

Judul: Modifikasi Pati Ganyong dengan Teknik Heat Moisture-Treatment (HMT) dan Aplikasinya dalam Pembuatan Sohun dengan Penambahan Hidrokoloid
Abstrak: Many tuber and root starches from local source are not widely used in food application due to their poor functional properties. Heat Moisture Treatment (HMT) was applied to native starch of Canna edulis to improve its functional characteristics. Canna edulis starch, was extracted from raw roots purchased from Ciamis. Its composition and physicochemical properties were investigated before and after HMT. Native or moistened canna starches at 20%, 25%, and 30% of final moisture were heat treated at 1000C and 1100C for 4, 8, and 16 hours. Optimation process was choosen based on the starch properties that give the relatively high gelatinization temperature, high setback viscosity, high gel strength, and low swelling power. After optimation process of HMT was reached, native and modified starches were applied in starch noodle formulation in order to know Heat-Moisture Treatment effects on noodle quality. The study of physical characteristics on starch noodle produced from 100% native starch or 100% modified starch with and without hydrocolloid showed that the characteristics of starch noodle from 100% native starch had no significant difference with those of 100% modified starch. The same result was found between noodles from 100% modified starch with and without hydrocolloid. Heat-Moisture Treatment gave no effect to the starch intended for noodle production.

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.
