Abstrak: Goat milk enriched naturally by Omega-3 through feeding with a mixture of carboxylate salt dry (MCSD), has a complete nutrition, but contrairely had a more distinctive smell goaty and high risk off flavour of rancidity. It made goat milk less desirable for consumption. Yoghurt is a fermented milk product that can be balanced the intestinal microflora between pathogens and beneficial bacteria. Cinnamon (Cinnamon burmanii) is a spices aromatic that rich in flavour and antioxidant. The addition of cinnamon extract in goat’s milk probiotic yoghurt aims to minimized the goaty smell and to maintain quality of product. This research has purpose to studied the effect of addition cinnamon extracts with different concentrations (3%, 4%, and 5%) on goat’s milk probiotic yoghurt characteristic include physical, chemical, microbiological and sensorial. The results showed that the addition of cinnamon extract influence the acidity (decreased pH value and increased total acid titrable) and sugar content of product, but there isn’t effect on viscosity, protein and fat content of yoghurt. Extract cinnamon addition at 4%-5% stimulated the growth of lactic acid bacteria to 0.7 log10 – 0.8 log10 CFU/ml. The hedonic-test showed that addition cinnamon extract wasn’t influence yoghurt acceptability, but the goaty flavour found less detectable in fermented product with addition of cinnamon extract becaused of the flavour resulted from fermentation process and volatile acid from cinnamon extract. It could be conclude that the fermentation and the addition of cinnamon extract increased the acceptability of goat’s milk probiotic yoghurt.

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: Pemanfaatan Data Boundary Layer Radar (BLR) Pada Troposfer Bawah Untuk Analisis Awan Hujan Penyebab Banjir
Abstrak: Penelitian ini secara umum ditujukan untuk mengidentifikasi dan menganalisis awan hujan penyebab banjir berdasarkan data Boundary Layer Radar (BLR). sebagai studi kasus bencana banjir besar di Jakarta 2002 lalu. Tahapan-tahapan yang dilakukan dalam penelitian ini ialah: (1) eksploratori data BLR periode Januari - Februari 2002, (2) mengidentifikasi awan hujan di Serpong dan (3) menghubungkan curah hujan di Serpong dengan kejadian banjir di Jakarta periode Januari-Februari 2002. Metode yang digunakan untuk identifikasi awan hujan ialah metode yang dikemukakan oleh William et af. (1995). Parameter-parameter yang digunakan dalarn pengidentifikasian awan hujan adalah data yang berasal dari beam vertikal yaitu echo power, kecepatan doppler dan lebar spektrum. Data curah hujan di Serpong diperoleh dari jenis tipping bucket (IKEDA-5) yang dipasang di Iingkungan BLR. HasH yang diperoleh. pada periode Januari-Februari 2002, curah hujan tertinggi di Serpong terjadi pada tanggal 29 lanuarl dengan intensitas scbesar 103.5 nunlhari dan terjadi secara terus menerus selama 4 jam dengan intensitas Icbih dari 10 mmljam. Awan bujan pada tanggal 29 tersebut teridentifikasi berasal dari awan konvektifkategori deep convective (konvektiftinggi). Dart basil identifikasi awan hujan periode lanuari-Februari 2002 dihubungkan dengan curah hujan, diperoleb bahwa curah hujan yang berasa! dati awan konvektif berkisar ;;::: 10 rrun/jam, sedangkan curah hujan dari awan stratiform :$ 6 mmljam. Pada periode Januari - Februari 2002, kejadian hujan di Jakarta (yang diambil dari data curah hujan 10 stasiun di Jakarta) hampir terjadi setiap hari dengan curah hujan tertinggi terjadi pads tanggal 29 Januari dengan intensitas sebesar 114.7 mmlhari
