Judul: Formulation of Centella asiatica Leaf Powder on Weaning Food as Functional Food Product
Abstrak: The aim of this study was examine the formulation of Centella asiatica leaf powder on weaning food as a functional food product. The study was conducted from April to September 2011. The main material used in this study was fres Centella asiatica leaf that will be processed into powder and another materials for the manufacture of weaning food. The instruments used in this study were oven blower FIR, diskmill, HPLC and AAS. The study design used in this study a Randomize Complete Blok Design. The results showed that fresh Centella asiatica leaf contain protein 4,58% wb, beta-karoten 88,76 ppm, vitamin C 79,14 mg/100g, Fe 43,26 mg/100g, Ca 1994,28mg/100g that needed by infants. Drying affects the physical and chemical properties of Centella asiatica leaf. The best drying temperatur for powder Centella asiatica was 550C. Centella asiatica powder has already safe quality on mikrobial contaminan. The time of adding Centella asiatica powder affected the density of weaning food. Average nutrition contant of weaning food Centella asiatica added, water 3,68%wb, protein 13,00%db, fat 2,10%db, beta-karoten 330,63ppm, vitamin C 216,16mg/100g, calcium 276,63mg/100g, Fe 14,29mg/100g, selenium 52,02mg/100g, asiatic acid 0,66%db. Average nutritional value of weaning food Centella asiatica added has met SNI and PAG. Overall the weaning food Centella asiatica was accepted by panelist, and the most aceptable weaning food has been qualified as safe weaning food instan powder.

Judul: Formulasi Bubur Instan Sumber Protein Menggunakan Komposit Tepung Kacang Merah dan Pati Ganyong sebagai Makanan Pendamping Air Susu Ibu (MP-ASI)
Abstrak: The purpose of this study was to formulate instant baby porridge as a source of protein weaning food based on red beans flour and canna starch composite. The design of this study was a complete randomized design with one factor which was the ratio of red beans flour and canna starch in composite composition as instant porridge ingredient (2:1, 3:1, and 4:1). Based on organoleptic test, F2 which used red bean flour and starch canna ratio by 3:1 was the choosen formula. The optimal time to brew the instant porridge was 62 seconds with amount of water used was 3 ml/g. The instant porridge bulk density was 0.61 g/ml and water absorption was 4.67g/g. This instant porridge contained 363 kkal/100 g, 16.57% protein, 1.48% fat, 70.84% total carbohydrate, 197.7 mg calcium, 8.17 mg zinc, and 16.48 mg iron. Protein digestibility of this porridge was 79.83%. As per 27 g serving size of this instant porridge can fulfill 22.25% protein, 55.25% iron, 27.63% zinc so that it can be claimed as food source of protein and zinc, and high iron.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
