Judul: Studi Pengaruh Lama Penyimpanan, Waktu Pencampuran, dan Penambahan Solvent pada Key Component Terhadap Flavor Release pada Minuman Ringan di PT. Tudung Putra Putri Jaya
Abstrak: Flavor is a sensation that comes and is caused by chemical components of volatile or non-volatile, which originated from natural or synthetic, and occur during eating or drinking. Now, flavor more rapidly adopted by food and beverage industry in Indonesia, especially in beverage productss. The purpose of this study is to understand changes that occur in flavor release in the final product by mixing the flavor concentrat with a solvent that is affected by the concentration of key components, mixing time and length of storage using a flavour 10x more concentrated than the ready to use (RTU) flavor. The Comparison that used between flavor concentrat and solvent are 60:40, 70:30, 80:20, 90:10, and 100:0. Before mixing between flavor concentrat and solvent in some concentration will be conducted preliminary research to find optimum speed mixing using concentrat 10x that diluted until the concentration is equal to the RTU flavors that have been used in products already marketed. Flavor has been mixed to be tested storage for 5 weeks with weekly observation. Observations were using the Different Test with Triangle Test sensory that will prove whether formulations are different or not with the RTU flavor. Further development in industrial scale study will be conducted later.

Judul: Penentuan faktor faktor yang memepengaruhi umur simpan dan penentuan umur simpan orange emulsion flavor dengan metode ASLT di PT. Firmenich Indonesia
Abstrak: Stability of emulsion product such as emulsion flavor is depend largely on interaction between hydrophilic and hydrophobic part of the product. Flavor compounds are generally soluble in oil (oil soluble), insert of these compounds in an emulsion makes it possible to deliver oil-soluble components into the water based. This research aims to estimate the shelf life of stabilized emulsions flavor using Accelerated Shelf Life Testing (ASLT) method. In this method, the storage condition is out of normal so that the deterioration will be occurred in a shorter time. Storage temperatures that used in this research were 20°C, 25°C,30°C and 35°C. Arrhenius equation used as a model in the estimation of shelf life with acceleration method. Arrhenius equation is an approach that uses the kinetic theory, which generally have reaction order 0 or 1 for food. The parameters that can be quantitatively measured are required to analyze the decline of quality with acceleration method. The parameters that used in this research were size particle, odor, spesific gravity, color and microbial. Based on the analysis of particle size, the shelf life of orange emulsion flavor are 0,266 months at 25 ° C. Based on the analysis of sensory attributes of smell, the shelf life of orange emulsion flavor are 5.38 months at 25 ° C, And based on the analysis of sensory attributes of color , the shelf life of orange emulsion flavor are 2.55 months at 25 °. The factors most influential in determining the shelf life of orange emulsion flavor based on AHP analysis include: homogenization, stabilizer, flavor, emulsifier, and type of packaging. While the final quality of the product parameters orange emulsion flavor are: particle size distribution, microbiology, flavor, pH, specific gravity, refraction index, and color.

Judul: Babesiosis pada kuda
Abstrak: Babesiosis pada kuda adalah penyakit menular yang di- sebabkan oleh Babesia caballi dan Babesia equi, yaitu pa- rasit protozoa perusak sel darah yang termasuk dalam genus Babesia. B. equi diduga oleh beberapa ahli termasuk dalam genus Theileria. Karena itu klasifikasi genus Babesia di- bicarakan dan siklus hidup B. caballi dan B. equi diulas. Kuda pada semua umur dapat terserang oleh dua parasite tersebut di atas. Tetapi kuda-kuda yang sudah dewasa (tua) lebih rentan jika dibandingkan dengan kuda-kuda yang masih muda. Kasus-kasus yang paling sering dijumpai adalah kasus-kasus yang bersifat akut walaupun kasus-kasus yang bersifat perakut, subakut dan kronik kadang-kadang terlihat. Serangan oleh parasit Babesia biasanya menyebabkan kerusаkan sel darah merah yang hebat sehingga kuda-kuda yang terserang menderita anemia hebat yang dapat menyebabkan kematian bila tidak segera diobati. Untuk mengatasi hal tersebut perlu dilakukan diagnosis yang tepat dan sedini mungkin. Diagnosis dapat dilakukan dengan cara memeriksa gejala-gejala klinik, preparat ulas darah, inokulasi hewan lain dan dengan mengadakan pemeriksaan secara serologik. Gejala-gejala klinik babesiosis pada kuda yang bersifat akut yang paling sering terlihat, ialah : nafsu makan menurun/hilang, lesu, bulu suram dan tidak mau bergerak. Kuda yang dilepaskan di padang rumput akan mengasingkan diri dan jalan sempoyongan. Faeces yang keluar berwarna cok- lat gelap, diselaputi lendir yang berwarna kekuningan dan urimenya berwarna merah tua. Temperatur tubuh meningkat menjadi 39.5 - 41°C dan pulsus meningkat. Terlihat dispnoe, perdarahan petechi pada mukosa membrana nictitans dan conjunctiva yang lebih pucat dari normal dan juga icteris. Kasus-kasus yang bersifat subakut gejala-gejalanya lebih ringan, tetapi bila tidak segera diobati maka gejala- gejala tersebut secara cepat menjadi hebat. Persendian lutut dan persendian gelang puyuh membengkak dan padanya ter- lihat oedema. Pada abdomen, dada dan kepala juga dapat di- temukan oedema. Gejala-gejala klinik yang terlihat pada kasus kronik adalah penurunan kondisi tubuh kuda secara progresif walaupun diberi makan yang banyak. Perubahan temperatur tidak jelas, nafsu makan berubah-ubah, icterus tidak jelas dan anemia mungkin hanya dapat dideteksi dengan menghitung sel darah merah dan kadar hematocrit…dst
