Judul: Characteristics of Sweet Potato Noodles Substitution by Sago Starch or Banggai Starch and Calcium Fortification
Abstrak: Ubi jalar adalah pangan lokal yang mendukung program diversifikasi pangan melalui pengaplikasian sebagai bahan baku pembuatan produk yang banyak disukai oleh masyarakat, salah satunya adalah mi. Penambahan pati sagu dan pati ubi banggai pada adonan mi ubi jalar diharapkan dapat meningkatkan kualitas mi yang dihasilkan, karena kedua pati ini memiliki karakteristik lebih mudah mengalami retrogradasi. Pengolahan menggunakan ekstruder dapat meningkatkan kualitas mi yang dihasilkan melalui pemberian panas dan shear stress. Peningkatan kualitas mi ubi jalar dari segi kandungan nutrisi dapat dilakukan dengan fortififikasi kalsium agar produk mi ubi jalar menjadi pangan sumber kalsium yang dapat mencegah terjadinya osteoporosis. Untuk memperoleh cara pengolahan mi terbaik, pada penelitian ini dilakukan tiga perlakuan, yaitu perbedaan jenis pati (pati sagu dan pati ubi banggai), suhu ekstrusi (90 dan 95ºC), dan penambahan air (35 dan 40%). Cara pengolahan terbaik dipilih berdasarkan hasil pengukuran warna, tekstur (kekerasan, kekenyalan, kelengketan, elongasi), dan cooking loss. Pada formula mi ubi jalar terpilih, dilakukan fortifikasi kalsium dengan dua garam kalsium yang berbeda, yaitu kalsium karbonat dan kalsium sitrat, masing-masing pada konsentrasi 20 dan 30% AKG dan dilanjutkan dengan pengukuran warna, tekstur, cooking loss, dan uji hedonik. Hasil pengujian pada mi ubi jalar menunjukkan bahwa perlakuan perbedaan jenis pati, penambahan air, dan suhu ekstrusi memengaruhi karakteristik fisik mi. Penambahan pati sagu 15%, air 40%, dan pengaturan suhu 95°C dapat menghasilkan mi ubi jalar dengan karakteristik warna agak gelap serta terdapat unsur warna merah dan kuning, memiliki nilai kekerasan diatas 3000 gf, dengan kekenyalan dan elongasi lebih tinggi dibandingkan formula yang lain, serta nilai kelengketan dan cooking loss yang lebih rendah. Fortifikasi kalsium karbonat ataupun kalsium sitrat, konsentrasi 20 dan 30 % AKG pada formula ini menunjukkan adanya perbedaan secara signifikan, yaitu dapat meningkatkan intensitas kecerahan, warna merah, dan kuning pada mi. Fortifikasi kalsium pada mi ubi jalar tidak mempengaruhi tingkat kekerasan, kekenyalan, kelengketan, elongasi, dan cooking loss. Penilaian panelis terhadap tingkat kesukaan menunjukkan bahwa secara keseluruhan mi ubi jalar fortifikasi kalsium dapat diterima oleh panelis., Sweet potato is a local food that supports food diversification programs through its application as a raw material for making products that are liked by common people, one of which is noodles. The addition of sago starch and banggai starch to the sweet potato noodle dough is used to improve the quality of noodles, because these two starches are more prone to retrograde. Processing using an extruder by applying heat and shear stress can improve the quality of the noodles produced. Improving the quality of sweet potato noodles in terms of the components contained can be done by calcium fortification so that sweet potato noodle products become food sources of calcium that can prevent osteoporosis. In order to obtained the best noodle processing method, three treatments were carried out in this study, there were different types of starch (sago starch and banggai starch), extrusion temperature (90 and 95ºC), and the addition of water (35 and 40%). The best processing method was selected based on the measurement of color, texture (hardness, elasticity, stickiness, and elongation), and cooking loss. In the selected sweet potato noodle formula, calcium fortification was carried

Judul: Formulation and Characteristics Dried Sago Noodle Added by Pumpkin (Cucurbita moschata) and Egg
Abstrak: Penambahan labu kuning dan telur dalam pembuatan mie sagu diharapkan dapat meningkatkan nilai nutrisi mie sagu serta membuat produk baru yang dapat diterima oleh masyarakat luas. Tujuan penelitian yaitu mengetahui formulasi penambahan labu kuning dan telur terbaik pada pembuatan mie sagu dilihat dari komponen fisikokimia dan daya penerimaan konsumen. Percobaan disusun dengan 4 perlakuan, perlakuan K tanpa penambahan labu kuning dan telur, perlakuan A dengan penambahan labu kuning 30% dan telur 3%, perlakuan B dengan penambahan labu kuning 30% dan telur 5%, perlakuan C dengan penambahan labu kuning 30% dan telur 10%. Daya terima konsumen diuji berdasarkan uji organoleptik serta perlakuan terbaik diuji menggunakan indeks efektivitas. Hasil uji produk terbaik secara fisikokimia yaitu mie sagu dengan penambahan pasta labu kuning 30% dan telur 10% dengan karakteristik kadar air 11,76%; kadar abu 1,11%; kadar lemak 7,31%; kadar protein 3,11%; kadar karbohidrat 76,31%; kadar serat 3,39%; cooking loss 18,65%; daya rehidrasi 115,23%. Daya terima yang paling disukai yaitu mie sagu dengan penambahan labu kuning 30% dan telur 3% dengan karakteristik warna 3,80 (agak menyukai); rasa 3,14 (netral); aroma 3,40 (netral); dan tekstur 3,80 (agak menyukai). Penambahan labu kuning dan telur dalam pembuatan mie sagu dapat meningkatkan karakteristik fisikokimia pada mie sagu., Addition of pumpkin and eggs in the production of sago noodles is expected to increase the nutritional value of sago noodles and create new products that can be accepted by the consumers. The purpose of the study was to find out the best formulation for adding pumpkin and eggs to the production ofsago noodles in terms of physicochemical components and consumer acceptance. The experiment was arranged with 4 treatments, treatment K without the addition of pumpkin and eggs, treatment A with the addition of 30% pumpkin and 3% eggs, treatment B with the addition of 30% pumpkin and 5% eggs, treatment C with the addition of 30% pumpkin and eggs. eggs 10%. Consumer acceptance was tested based on organoleptic tests and the best treatment was tested using an effectiveness index. The results of the best physicochemical product test were sago noodles with the addition of 30% pumpkin paste and 10% eggs with a water content characteristic of 11.76%; 1.11% ash content; fat content 7.31%; protein content 3.11%; carbohydrate content 76.31%; fiber content 3.39%; cooking loss 18.65%; rehydration power 115.23%. The most preferred acceptability is sago noodles with the addition of 30% pumpkin and 3% eggs with a color characteristic of 3.80 (somewhat like); taste 3.14 (neutral); fragrance 3.40 (neutral); and texture 3.80 (rather like). The addition of pumpkin and eggs in the production of sago noodles can improve the physicochemical characteristics of sago noodles.

Judul: Truncated Stop Loss as a Optimal Solution of Reinsurance Agreement in One-Period Model
Abstrak: Reinsurance is one of risk management efforts of an insurance company, which is called the cedent. Similar with insurance, reinsurance constitutes the cedent to pay the premium. We consider one-period reinsurance model and derive a rule which minimizes the ruin probability of the cedent for a fixed reinsurance premium. Therefore, it is needed to construct an optimal reinsurance agreement for the cedent. The premium is calculated according to four different principles, i.e. economic, generalized zero-utility, Esscher, and mean-variance principles. Stop loss is a reinsurance contract which protect the insurance company for losses that exceed a certain amount. The result of this research shows that a truncated stop loss is an optimal agreement in the class of all reinsurance contracts with various premiums calculated using above mentioned principles.
