Judul: Fortifikasi Mikroenkapsulasi Besi pada Biskuit Tepung Komposit Pisang, Ubi Jalar, Tempe, dan Wortel sebagai Pencegah Anemia Defisiensi Besi
Abstrak: Penelitian bertujuan untuk manghasilkan biskuit berbahan dasar tepung pisang, ubi jalar, tepung tempe, dan tepung wortel dengan fortifikasi mikroenkapsulasi Fe untuk menanggulangi masalah anemia defisiensi besi. Pembuatan biskuit menggunakan bahanbahan lokal dengan metode dry mixing sebagai upaya diversifikasi pangan. Mikroenkapsulasi Fe dilakukan dengan teknik spray drying yang berbahan dasar ferrous sulphate heptahydrate dengan maltodekstrin dan gum powder sebagai penyalut. Jumlah mikrokapsul besi yang ditambahkan yaitu sebesar 33%, 35%, 37% AKG zat besi usia anakanak 7-9 tahun untuk mencapai klaim tinggi besi. Formula terpilih berdasarkan skor ranking berdasarkan nilai mutu organoleptik. Kandungan gizi formula terpilih yaitu 1.80% air, 2.81% abu, 14.00% lemak, 9.13% protein, 55.84% karbohidrat, dan 8.3 mg/100 gram zat besi (tinggi besi). Nilai bioavailabilitas zat besi dari biskuit sebesar 20.00% (tinggi biavailabilitas). Biskuit dengan fortifikasi mikrokapsul besi diharapkan dapat dijadikan sebagai pangan alternatif pencegah anemia defisiensi besi.

Fortification of Iron Microencapsulated to composite flour from banana, sweet potato, soybean, and carrot as an alternative food to prevent iron deficiency anemia. Supervised by EVY DAMAYANTHI. The objective of this research was to create a biscuit flour-based from sweet potato, banana flour, soybean flour, and carrot flour with iron microencapsulated fortification to prevent the problem of iron deficiency anemia. The method for this research were making biscuits using local ingredients with dry mixing method, iron was microencapsulated using maltodextrin and gum powder as the coating materials by the spray drying technique, and iron bioavailability of biscuit measured by dialysis bag. The amount of iron microencapsulated was added about 33%, 35%, and 37% from iron RDA of children’s aged 7-9 years old to achieve food with high iron content. The selected formula’s score was 74% of panelist accept the biscuit based on the score ranking of the organoleptik quality. Contributions of biscuits towards energy sufficiency and iron seen from the proximate test. Nutrient content of the best formula were 1.80% of water, 2.81% of ash, 14.00% of fat, 9.13% of protein, 55.84% of carbohydrate, and 8.3 mg/100 g of iron (high iron). The iron bioavailability was 20.00% (high bioavailability). Biscuit with iron microencapsulation can be used as an alternative food to prevent iron deficiency anemia, because every serving size contain 4.15 mg iron which has a claim to food with high in iron.

Judul: Formulasi Biskuit Substitusi Tepung Ubi Kayu dan Ubi Jalar dengan Penambahan Isolat Protein Kedelai serta Mineral Fe dan Zn untuk Balita Gizi Kurang
Abstrak: Moderate undernutrition is one of major nutritional problems in Indonesia, with a prevalence of 13%. Instead of lack of energy and protein intake, undernutrition children commonly are deficient in iron and zinc. One of the effort to overcome this problem is by giving them foods which contain high energy and protein as well as met with iron and zinc requirement. The objective of this research was to formulate biscuit which were made of cassava flour, sweet potato flour, and soy protein isolate with addition of Fe and Zn as side dish of moderate undernutrition children. Cassava and sweet potato flour is an indigenous food of Indonesia which high in energy content, so can be used to substitute wheat flour in making biscuits as source of energy. To increase protein content of biscuit, it was used soy protein isolate which contains about 90% protein. Gizikita is a multivitamin mineral supplement containing high iron and zinc in microcapsules form. Design of this research was experimental which factors that used were kind of flour (cassava, sweet potato, and composite flour) and level of flour substitution (20%, 40%, and 60%). Based on organoleptic test showed that the selected formula was A1B1 (20% cassava substitution). Biscuits A1B1 has 457 Kcal/100g of gross energy; 2.960,2 gram force of hardness; 8,31% water content (wb); 3,12% ash (db); 13,93% protein (db); 14,23% fat (db); 68,71% carbohydrate (db); 8,38 mg/100g Fe; 10,61 mg/100g Zn; 81,48% protein digestibility; 10,87% bioavailability of Fe ; and 29,45% bioavailability of Zn.

Judul: Implementation of Spatio-Temporal Change Query in Relational Database.
Abstrak: Geographic object changes in various views. Object changes are recorded using a model of static storage. No historical connection between old version data and new version data has been built. For that, a storage model of spatio-temporal queries that can analyze spatio-temporal changes has been developed. The object changes the geometry are grouped according to the taxonomy of Spatio-Temporal Pattern Change. This research has been able to apply the query patterns change including born, expand, merge, contract, split, normal and die. This query based on geometric (area) changes. The implementation of spatio-temporal change queries represents an object changes continuously with easy, change detection is done by comparing two versions of data. Keyword: spatio-temporal change query, spatio-temporal change pattern.
