Judul: Makanan Siap Santap Tinggi Kalsium Berbahan Dasar Tepung Jagung dengan Penambahan Tepung Ikan Lele Dumbo (Clarias gariepinus sp.) bagi Pekerja Full-Time
Abstrak: Penelitian ini bertujuan untuk membuat snack food praktis tinggi kalsium berbahan dasar tepung jagung dengan penambahan tepung ikan lele dumbo (Clarias gariepimus sp.) bagian kepala dan badan agar dapat dengan baik diterima oleh kelompok sasaran. Formulasi pembuatan produk terdiri dari formulasi tepung jagung sebagai pangan subtitusi terigu sebanyak 50%, 75%, dan 100%, serta formulasi penambahan tepung ikan lele dumbo sebanyak 23% (F1), 25.5% (F2), dan 28% (F3). Formula terpilih berdasarkan uji organoleptik adalah produk dengan substitusi tepung jagung sebesar 50% atau dengan penggunaan tepung jagung sebanyak 75 g dan penambahan tepung ikan lele sebanyak 25.5% (F2). Tingkat kekerasan produk berdasarkan analisis sifat fisik adalah sebesar 678.7 g force. Analisis kimia produk menunjukkan bahwa 100 g produk memiliki kadar air 32.3%bb, kadar protein 10.0%bb, kadar lemak 11.4%bb, kadar abu 4.5%bb, karbohidrat 41.7%bb, dan 402.1 mg kalsium. Hasil analisis kimia menunjukkan bahwa produk dapat dikategorikan sebagai pangan kudapan tinggi kalsium. Produk pangan ini termasuk ke dalam kategori tinggi tingkat penerimaannya berdasarkan hasil uji daya terima kepada kelompok sasaran (pekerja full-time).

Judul: Formulasi Flakes Pati Garut dan Tepung Ikan Lele Dumbo (Clarias gariepinus) sebagai Pangan Kaya Energi Protein dan Mineral
Abstrak: The objective of this study was to produce arrowroot starch flakes with dumbo catfish (Clarias gariepinus) flour, as a rich energy, protein and mineral food for elderly. Design of this study was using Complete Randomized Design with four formula and each combination was replicated two times. A selected formula was determined based on semi trained panelists preference. Acceptance of selected flakes formula was examined by elderly using hedonic test. Flakes by addition of 33% of dumbo catfish flour was the selected formula. The chemical properties for selected flakes were as follows 4.00% of water content, 4.84% of ash content, 16.90% of protein content, 5.21% of fat content, 69.06% of carbohydrate content, 14.48% of calcium content and 8.61% of phosphorus content. The selected flakes contain 390.71 Kcals energy per 100 g. The selected flakes had contributed more than 20% of energy, protein, calcium and phosphorus for elderly people so it can be claimed as a food product rich in energy, protein and mineral

Judul: : Persamaan Tunggal sebagai Representasi Kurva Komposit
Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
