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.

Judul: Penentuan Model Umur Simpan Produk Minuman Mengandung Susu Berkemasan Botol HDPE dengan Pendekatan Arrhenius di PT Danone Indonesia
Abstrak: Informasi umur simpan produk pangan sangat penting dalam menjamin mutu untuk waktu yang lama. Kewajiban pencantuman umur simpan telah diatur dalam undang-undang Pangan No. 7 tahun 1996 serta peraturan pemerintah No. 69/1999 tentang Label dan Iklan Pangan. Produk minuman mengandung susu yang disterilisasi memiliki umur simpan yang lama, maka dibutuhkan metode yang cepat, tepat, dan efisien untuk menentukan permodelan umur simpan, yaitu dengan metode akselerasi model Arrhenius. Tujuan penelitian ini yaitu membuat model umur simpan untuk memprediksi waktu penyimpanan dan melihat gambaran nilai pH dan sensori pada batas waktu yang telah ditetapkan PT Danone Indonesia serta melihat korelasi antara parameter pH dan sensori. Penelitian ini dilakukan dengan menggunakan produk minuman mengandung susu berperisa strawberry cream (SC) kemasan HDPE (High Density Polyethylene). Pengujian dilakukan dengan masing-masing disimpan dalam penyimpanan normal pada suhu 30 0C selama 6 bulan dan penyimpanan akselerasi pada suhu 35 0C, 40 0C, dan 45 0C selama 6 minggu. Pengambilan data dilakukan berdasarkan parameter kritis yaitu parameter pH dan sensori dengan beberapa atribut yaitu Kualitas Keseluruhan, Intensitas Keseluruhan, Kemanisan, Rasa Susu, Aroma Asing, dan Intensitas Keseluruhan. Modeling umur simpan yang paling representatif digunakan yaitu model ekponensial 2P atau model Arrhenius ordo reaksi 1. Umur simpan produk ditentukan oleh faktor kemasan, suhu proses UHT, dan formula. Korelasi hubungan antara pH dan sensori menunjukkan penurunan nilai pH diikuti dengan penurunan nilai sensori sampai batas standar sehingga didapat waktu umur simpan yaitu 24 minggu.

Judul: Etno-ornitologi Burung Kancilan Flores (Pachycephala nudigula nudigula Hartert 1897) pada Masyarakat Lio di Taman Nasional Kelimutu
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.
