Judul: Basic Taste Threshold and Preferences in Food Matrices by Multicultural Approach in Indonesia
Abstrak: Taste is the most important parameter for food acceptance. Each of the basic tastes; sweet, bitter, sour, salty, and umami, has its minimum concentration to be detected or identified by human senses, called threshold. Cross-cultural studies showed that eating habit was one of the factors that affect taste threshold and preference of food, associated with taste intensity in the food. Indonesia is an archipelagic country with multiethnic citizens with more than 740 ethnic groups. Each ethnic group has its unique food taste and eating habits. Bogor Agricultural University as one of the best university in Indonesia could be a good representative of Indonesian multiethnicity. First year undergraduate students are good representatives. They have lived in Bogor for a short time, thus it can be assumed that their eating habit based on ethnicity still remains. The aim of this study was to evaluate taste threshold of three basic tastes (sweet, bitter, and salty) and preference in food matrices (tea, coffee, and vegetable soup broth) of three ethnic groups in Indonesia. The other aims were to evaluate the influence of gender to taste threshold and preference in Indonesia and to evaluate the correlation between taste threshold and its preference in food matrices. This study was conducted in four stages: (1) preliminary study to determine concentration series of taste threshold and preference tests, (2) panelist recruitment, (3) evaluation of taste threshold and preferences in food matrices, and (4) data analysis. The panelists were first year undergraduate students in Bogor Agricultural University recruited from regional student organizations of three ethnic groups: Minangese, Javanese, and Nusa Tenggara. Recruitment criterias are age (17-25 years old) and having lived in the area of ethnic origin for 10 years minimum. Each ethnic group was represented by 30 panelists, with the proportion 60:40 for female and male. Sensory tests were conducted in Food Sensory Analysis Laboratory, SEAFAST Center, in individual booths on room temperature (25oC). Taste threshold determination was conducted by using three-alternative force choice (3-AFC) ascending concentration series method of limits (ASTM E679), while preference test was conducted using Rank-Rating method. Data analysis were using Microsoft Excel for Windows 2007 and SPSS 20. Analysis of questionnaire data showed that umami and sweet taste were dominantly found in Minangese, Javanese, and Nusa Tenggara foods. Minangese foods were uniquely dominant in spicy taste. The beverages from three ethnic groups were dominant in sweet taste. The average of sweet taste threshold of Indonesian was 6.027 mM of sucrose, 0.713 mM of caffeine for bitter taste, and 1.982 mM of NaCl for salty taste. Minangese had the highest threshold for sweet taste (8.139 mM of sucrose) and bitter taste (0.770 mM of caffeine). Javanese had the highest threshold of salty taste (2.177 mM of NaCl). Panelists from Nusa Tenggara had the lowest threshold of all tastes (4.070 mM of sucrose, 0.671 mM of caffeine, and 1.895 mM of NaCl). Statistical analysis showed that ethnic groups have significantly affected sweet taste threshold (p=0.034) between Nusa Tenggara and Minangese. Gender differences showed that female panelists had lower threshold of all tastes. Statistical analyses of threshold differences

Judul: Studi Preferensi Varietas Unggul Beras pada Konsumen dari Beberapa Wilayah yang Mewakili Konsumen Beras Indonesia
Abstrak: Indonesia is an agricultural country. One of the most important agriculture product is rice which is a staple food for people of Indonesia. Every province in Indonesia has a difference of high yielding variety of rice. It relates to the acceptance and preference of the consumers which are influenced by social environment and origin of area of the consumers where they live. The preference of consumers and the palatability determine quality and sensory characteristic of rice. This study aimed to characterize the sensorial quality of rice, identify preference of consumers to cooked rice, and to relate between the preference and the sensory descriptive of cooked rice. Four domestic high yielding varieties were evaluated by trained sensory panels and 152 peoples who consist of peoples from West Java, West Sumatra, South Sulawesi, and Papua. The result showed that the preference of consumers from West Java and South Sulawesi was influenced by the taste and texture of cooked rice. They less liked taste and texture of cooked rice from Cisokan. Thr preference of these consymers to the taste and texture of Ciherang and Membramo rice was more than those of Cisokan. However, the consumers from West Sumatra less prefered taste, aroma, and texture of cooked rice from Ciliwung. The consumers from Papua less prefered aroma of cooked rice from Ciherang. According to consumers, the sensory characteristics most important to acceptance of cooked rice were pandan aroma, vanilla aroma, nutty aroma, salty, umami, hardness, particle size, and roughness of mass. Using descriptive data, the researcher evaluated predictive models of cooked rice from high yielding varieties’ preference. Data collected here could be useful for Indonesian’s government in developing an understanding of the drivers of high yielding varieties of rice acceptance.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
