Abstract

Supercritical carbon dioxide technology was a non thermal processing which might be applied on tempe to preserve its freshness. The aim of the research was to study the effect of supercritical CO2 on the color and texture of tempe, and to identify the aroma of tempe after processed with supercritical CO2. The experiment was carried out using CompletelyRandomized Block Design with three replications. The experimental factors were pressure treatmentat supercritic (Ps) and liquid (Pc), and treatment time (T) at T1, T2, T3, T4 of 5, 10, 15, and 20 minutes, respectively. The results showed that the treatment of pressures, time and their interactions significantly affected the color of ?L*, ?a*, ?b*, ?E*, but not significantly affected the textures.The best treatment was PcT1 producing the tempe with the value of ?L*-2.13; ?a*0.28; ?b*0.97 dan ?E*0.77. Several volatile aromas of tempe were extracted due to the supercritical CO2 treatment, but it also caused the formation of new volatile aroma compounds.

Abstract

The objective of this experiment was to determine the effects of zinc supplementation on health status in dairy calves. Nine Frisian Holstein (FH) at 6-10 months of age were used in this experiment and divided into three groups. First group (no added Zn) for control, the second group was added 60 ppm Zn, and the third group was added 120 ppm Zn. Zn was administered daily for three months. Blood samples were collected from the jugular vein and anticoagulated with EDTA. Whole blood were used for measuring erythrocytes, hemoglobin concentration, hematocrit value, total leukocyte count, and leukocyte cell types. The results showed that no difference among groups for hematological parameters and the value of hematology were in the range values references. In conclusion, 60 and 120 ppm Zn supplementation in the feed is relatively safe for health.

Abstract

Kejadian babesiosis pada anjing umumnya disebabkan oleh Babesia canis  dan Babesia gibsoni. Babesia canis memiliki ukuran yg lebih besar dibandingkan dengan Babesia gibsoni. Babesia canis memiliki ukuran 4 ? 5 um, sedangkan  Babesia gibsoni memiliki ukuran 1 ? 3 um (Zajac & Conboy, 2011). Babesia sp menginfeksi anjing dalam bentuk sporozoid yang terdapat dalam saliva caplak ketika caplak menggigit inang. Sporozoid akan berpenetrasi dalam RBC dan akan mengalami fase parasitic dalam RBC. Sporozoid yg telah masuk dalam RBC disebut tropozoid. Tropozoid dalam RBC akan mengalami pembelahan biner menjadi merozoid. Bersamaan dengan lisis eritrosit, merozoit akan menginfeksi eritrosit yg lainnya (Chauvin et al. 2009).Gejala klinis yg muncul akibat infeksi Babesia sp antara lain: lemas, tidak nafsu makan, demam, anemia, splenomegaly, lymphadenopathy, ikhterus, diare, muntah, melena, dan gagal ginjal (Barr & Bowman 2006).Pengobatan Babesiosis pada anjing (B. gibsoni) dg menggunakan Clindamycin 25 mg/kg BB, per oral 2x per hari selama 14 hari dapat secara bertahap menurunkan tingkat parasitemia dan menyebabkan perubahan morfologi yg diindikasikan adanya degenerasi parasit misalnya, segmentasi, penurunan ukuran, kerusakan inti /  nucleus sel, penurunan atau tidak terlihatnya sitoplasma (Wulansari R. dkk, 2003).

Abstract

Permintaan dunia terhadap protein hewani sangat besar dan terus meningkat setiap tahunnya. Kebutuhan yang meningkat tidak dibarengi dengan kemampuan penyediaan protein hewani yang cukup sehingga sebagian besar dipenuhi melalui import. Pemenuhan protein dalam negeri diharapkan mampu meningkatkan kualitas maupun kuantitas daging melalui perbaikan mutu nutrisi sehingga mampu bersaing dengan pihak luar. Salah satu sumber protein hewani selain dari ternak potong, adalah memanfaatkan sapi jantan dari sapi perah FH. Oleh karena itu ternak jantan dapat digunakan sebagai alternatif sumber protein hewani dalam upaya untuk penyediaan pangan asal ternak.  Pembangunan peternakan diarahkan agar produk ternak dalam negeri mampu bersaing dengan produk ternak impor dalam rangka memantapkan ketahanan pangan nasional. Mineral Zn dilaporkan mampu memperbaiki skor marbling karkas [1].  Hal ini penting untuk memperbaiki kualitas karkas daging sebagai sumber protein hewani. Belum banyak informasi tentang efek suplementasi Zn terhadap pertambahan bobot badan terutama pada sapi FH jantan. Oleh karena itu pengamatan tentang suplementasi Zn terhadap performa (bobot badan) pada sapi FH jantan perlu dilakukan.

Abstract

Lactobacillus sp B441 and II442 were species of lactic acid bacteria isolated from tempoyak, a kind of food fermented made from durian flesh. Staphylococcus aureus is a pathogenic bacteria that has natural habitat on the surface of human body such as on the skin and in mucous membranes like the nose. Contamination of Staphylococcus aureus was a risk factor in tempoyak fermentation, especially, during taking the durian flesh from seeds. The aim of this research was to observe antagonistic property of Lactobacillus sp B441 and II442 isolated from tempoyak during low temperature fermentation against Staphylococcus aureus. Phenotypic identification using API 50 CHL test kit indicated that isolates were Lactobacullus plantarum B441 and Lactobacillus plantarum II442. Based on co-culture analysis show that isolates of Lactobacillus plantarum B441 and II442 have bactericidal effect against Staphylococcus aureus ATCC 25923 as a indicator of pathogenic bacteria. At 25 th hours, population of Staphylococcus aureus ATCC 25923 in mix-culture with Lactobacillus plantarum B441 and Lactobacillus plantarum II442 decreased 3 – 4 log cycle from initial population. However, population of Staphylococcus aureus ATCC 25923 in mono-culture increased 2 log cycles at 25 th hours.  ABSTRAKLactobacillus sp B441 dan II442 merupakan spesies bakteri asam laktat yang diisolasi dari tempoyak yaitu makanan fermentasi dari daging buah durian. Staphylococcus aureus adalah bakteri patogenik yang habitat alaminya pada permukaan kulit manusia dan membran mukosa seperti hidung. Proses fermentasi tempoyak khususnya saat pemisahan daging buah durian dari bijinya beresiko terkontaminasi oleh Staphylococcus aureus. Tujuan dari penelitian ini adalah mengkaji sifat antagonistik dari Lactobacillus sp B441 and II442 yang diisolasi dari tempoyak terhadap Staphylococcus aureus. Identifikasi secara fenotif menggunakan API 50 CHL test kit menunjukkan bahwa isolat bakteri asam laktat tersebut adalah Lactobacullus plantarum B441 dan Lactobacillus plantarum II442. Berdasar uji co-culture diketahui bahwa kedua spesies tersebut mempunyai efek bakterisidal terhadap bakteri Staphylococcus aureus ATCC 25923.

Abstract

The purpose of this study was to determine the pasting properties of modified canna starch produced with heat moisture treatment (HMT) and addition of xanthan gum (XG) for gluten free bread. This research used a Factorial Randomized Completely Design with two factors as treatments for pasting properties and one factor of starch?s type for bread dough formulation. The first factor (A) was HMT temperatures (80 and 100oC) for 8 hours at canna starch water content of 15% and the second (C) was the concentration of XG (0; 0.5; 1; 1.5; 2% w/w). The parameters determined were pasting properties and specific volume, texture, and sensory analysis for bread. The results showed that all treatments and their interaction had significant effect on the pasting properties, while XG concentration had no significant effect on the gelatinization time. Meanwhile, interaction between HMT temperatures and XG concentration had no significant effect on the setback. The best treatment was canna starch modified by HMT at 80oC and added with 1.5% of xanthan gum, with 72.25±0,23oC of gelatinization temperature; 6.16±0.04 minutes of gelatinization time, 4556±107.01 cP of peak viscosity, 5141±64.00 cP of final viscosity, 2235±27.51 cP of breakdown, and 2818±15.52 cP of setback. The specific volume of the bread produced was 2.85±0.017 cm3/g, texture of 109.03±7.50 gf and average hedonic scores for taste, color, texture and aroma of 5.34; 5.46; 5.56 and 5.80 respectively (5=least liked, 6=liked).

Abstract

Long-tailed macaque (Macaca fascicularis) belongs to least concern categories of animals, and often found in various regions of Indonesia, including Kupang, East Nusa Tenggara. Their habitat are one of the tourist destinations, causing interaction between them and humans. The interaction facilitates the transmission of disease agents, for example endoparasit. This study was conducted to find out the diversity and prevalence of endoparasites in long-tailed macaque, weather effects, and zoonotic potential in Kupang City. Fifty fecal samples were collected and analyzed using formalin ethyl acetate concentration technique (FECT). A total of six endoparasites were recovered including four helmints (hookworm, Strongyloides, Toxocara, and Acantocephala) and two protozoans (Balantidium coli and Entamoeba sp.). The highest prevalence of infection occurred in February (rainfall 302.4 mm) and consisted of hookworm (86%) and B. coli (66%). If rainfall increases, prevalence will also increase. The high prevalence of parasites is not always associated with the appearance of clinical symptoms. An individu diagnosed with parasites if the eggs or cysts have been identified from the faeces. The high prevalence caused by the absence of deworming program. Among the endoparasites that have been found, some of which are potentially zoonotic, such as: Strongyloides sp., Toxocara sp., Acanthocephala, B. coli, and Entamoeba sp.&nbsp;
