Judul: Penentuan Parameter Pengujian dalam Pendugaan Umur Simpan Produk Minuman Susu UHT Asam di PT Danone Indonesia
Abstrak: Shelf lifeis one of theinformationsthatmust be statedbythe food manufactureron the packaging. It is regulatedin theFoodAct1996 andGoverment Regulation No.69of 1999. This researchpurpose isdetermining the test parameters to estimate shelf life ofUHT acidifiedmilkbeverageusingArrhenius acceleratedtest method. Determination of test parameterswasperformed on5quality parameterssuch aspH, sedimentation, sensoricalcharacteristics, color, andtotal acidityfor products which kept in 35oC, 40oC, and45oC for5 weeks. From sensory test results showed that color, taste, and aroma of products significantly different during storage time while the viscosity was not changing.Based on the results the appropriate parameters to predict the shelf life ofthis product are color, sediment and sensory test, while the pH value and the total acidityhave no impact on the product during the shelf life.

Judul: Penentuan Parameter Kritis untuk Pendugaan Umur Simpan Susu UHT yang Diasamkan dengan Metode Arrhenius di PT Danone Dairy Indonesia
Abstrak: Penelitian ini bertujuan untuk menentukan parameter kritis yang akan digunakan untuk menduga umur simpan susu UHT yang diasamkan menggunakan Metode Arrhenius. Parameter yang diujikan untuk menentukan umur simpan adalah pH, sedimentasi, total asam tertitrasi, warna, dan sensori. Penentuan umur simpan dari susu UHT yang diasamkan dilakukan dengan menyimpan sampel pada suhu 350C, 400C, dan 450C selama sembilan minggu. Sampel memiliki nilai awal untuk pH sebesar 3,72; total asam tertitrasi sebesar 0,43; persen sedimentasi sebesar 2,65%; nilai L sebesar 82,58; dan nilai absorbansi 3,889. Parameter kritis yang digunakan untuk menentukan umur simpan dari susu UHT yang diasamkan adalah parameter warna. Umur simpan produk untuk penyimpanan suhu 300C, 350C, 400C, dan 450C adalah 27 minggu, 15 minggu, 8 minggu, dan 4 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.
