Judul: Study the manufacturing goat milk yoghurt and diversification taste with spices syrup
Abstrak: The research aims to make a set of goat milk yogurt and diversification taste of the best formula with syrup made from spices through the test characteristics of sensory, physical, chemical, and microbiological. Formulation of goat milk yogurt is Esa15 (ratio of Etawah goat’s milk and Saanen goat’s milk 1:5, starter culture ratio of 1:1), K11 (goat's milk without the addition of skim milk, starter culture ratio of 1:1), K23 (goat's milk without the addition of skim milk, starter culture ratio of 2:3), K32 (goat's milk without the addition of skim milk, a comparison of culture starter 3:2), KS11 (goat's milk with the addition of skim milk, starter culture ratio of 1:1), KS23 (goat's milk with the addition of skim milk, starter culture ratio of 2:3), and KS32 (goat milk with the addition of skim milk, comparison of starter cultures 3:2). The results of the hedonic test showed that selected one formula goat milk yogurt that is most preferred by panelists is KS32. KS32 formula of goat milk yogurt used for diversification taste with the addition of spices syrup. Spice syrup formula consists of ginger syrup, CKA syrup (cloves, cardamom, anise), and CKK syrup (cloves, cardamom, cinnamon). Furthermore the stability for yogurt made goat's milk without the addition of syrup (plain) and goat's milk yogurt with the addition of syrup is determined. Based on observations, the selected formula indicating a decrease of pH, increased total solid soluble, and a decrease of total lactic acid bacteria in yogurt during storage in 10oC and safe for consumption for 15 days. The yogurt contains moisture content ranged from 81.58 to 83.19% (wet basis), carbohydrate content ranged from 8.99 to 10.91% (wet basis), protein content ranged from 4.05 to 4,63% (wet basis), fat content ranged from 2.60 to 2.65% (wet basis), and ash content ranged from 0.78 to 0.82% (wet basis).

Judul: Diversifikasi Es Krim Susu Kambing dengan Penambahan Yoghurt Probiotik
Abstrak: Susu kambing memiliki nilai nutrisi dan nilai medis yang baik. Konsumsi susu kambing dalam bentuk cair masih dibatasi oleh rendahnya daya terima konsumen terhadap produk tersebut sehingga perlu diperkenalkan cara penyajian dalam bentuk lain. Diversifikasi produk es krim susu kambing dapat dilakukan dengan penambahan yoghurt probiotik. Proses fermentasi pada yoghurt diharapkan dapat menghilangkan bau khas kambing, sedangkan penambahan probiotik melalui penambahan yoghurt dapat menghasilkan es krim yang bermanfaat bagi kesehatan manusia. Penggunaan starter ABT-5® yaitu campuran kultur Lactobacillus acidophilus, Bifidobacteria dan Streptococcus thermophilus merupakan mikroorganisme yang memberikan keuntungan bagi induk semangnya karena mampu menciptakan keseimbangan mikroflora usus. Selain berperan sebagai probiotik, pada proses fermentasi bakteri asam laktat menghasilkan asam yang lebih mudah dicerna tubuh.

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.
