Abstrak: Food safety and food quality need to be guaranteed by the manufacturer as a protection for consumer safety. The guarantees can be provided through the determination of shelf life using the model of shelf life prediction. This study was conducted to determine the kinetic shelf life prediction model with the Arrhenius approach for products containing milk chocolate, processed by UHT and packed with a pouch. Furthermore, this study are aimed to determine the critical factors that influence pH and sensory, to choose the most appropriate sensory attributes in shelf life prediction, and find the correlation between pH and sensory parameters with shelf life based on kinetic model. Prediction models were obtained through the analysis of the products, which were stored at 35oC, 40oC, 45oC for 6 weeks and at 30°C for 6 months, and based on the pH and sensory parameters (overall quality, overall intensity, sweetness, milkiness, flavor intensity and off notes). Based on analysis, the output models are exponensial 2P model, exponensial 3P model and linier model. The test results showed that the most suitable model for estimating shelf life are the exponential 2P model for pH parameter and the linier model for sensory parameter. Packaging is a factor that influence pH alteration, whereas for sensory parameters are the processes and formula.

Abstrak: Information and labeling about shelf life becomes very important for industry, consumers, and distributors related on food safety and to provide quality assurance until the product delivered to the consumer. This research was conducted to estimate shelf life of UHT chocolate milk beverage with two steps which consisted of critical quality attribute screening and shelf life determination using Accelerated Shelf Life Testing (ASLT) method with Arrhenius approach. Test parameters used in this study were pH, sedimentation, color, thiobarbituric acid (TBA) values, and sensory . There were three conditions to store samples, i.e 350C, 400C, and 450C for nine weeks. Based on the results of determination of parameters test, the most appropriate parameter to estimate the shelf life of the product is pH, while the sedimentation and color parameter are less appropriate because the parameter value is relatively constant and it is not affected by temperature changes.

Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
