Judul: Pendugaan Umur Simpan Susu UHT Cokelat dengan Metode Akselerasi Model Persamaan Arrhenius di PT Danone Indonesia
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.

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: Prevalence of Bird Lice on Rock Pigeon (Columba livia) in 99Wonderland Park, Selangor, Malaysia
Abstrak: Rock Pigeon (Columba livia) have coexisted with humans for thousands of years and are used for various purposes such as food and in sports. Rock pigeons may have the potential to be infested with a wide range of ectoparasites, which can have a significant impact on their life cycle. This study aims to measure the prevalence of Columba livia with bird lice in 99Wonderland Park, Selangor, Malaysia in the year 2020 and to ascertain the impact of bird lice on the health of these infested birds. Data were collected from clinical records for the month of January to December in the year 2020 from 99Wonderland Park, Selangor, Malaysia. Lice were identified in 42 of the 80 Rock pigeons examined so, the overall prevalence of lice infestations was 52.5%. The prevalence of ectoparasites was found to be higher in young Rock pigeons (60.4%) as compared to adult Rock pigeons (37.4%). Columbicola columbae (wing lice) and Colpocephalum turbinatum (body lice) are two species of lice that have been detected. Body lice were more prevalent in young Columba livia birds at 47.6% whereas wing lice were more prevalent in adult Columba livia birds at 16.7%. Most of the lice were found in the thorax and abdomen area followed by the head and neck area., Merpati Batu (Columba livia) telah hidup berdampingan dengan manusia selama ribuan tahun dan digunakan untuk berbagai keperluan seperti makanan dan olahraga. Merpati batu dapat terinfestasi dengan berbagai ektoparasit, yang dapat berdampak signifikan pada siklus hidup mereka. Penelitian ini bertujuan untuk mengetahui prevalensi Columba livia dengan kutu burung di 99 Wonderland Park, Selangor, Malaysia pada tahun 2020 dan untuk memastikan dampaknya terhadap kesehatan burung yang terinfestasi. Data dikumpulkan dari catatan klinis dari bulan Januari hingga Desember tahun 2020 dari 99Wonderland Park, Selangor, Malaysia. Kutu diidentifikasi pada 42 dari 80 merpati batu yang diperiksa sehingga, prevalensi keseluruhan infestasi kutu adalah 52,5%. Prevalensi ektoparasit ditemukan lebih tinggi pada merpati batu muda (60,4%) dibandingkan dengan merpati batu dewasa (37,4%). Columbicola columbae (kutu sayap) dan Colpocephalum turbinatum (kutu badan) adalah dua spesies kutu yang telah ditemukan. Kutu badan lebih banyak ditemukan pada burung Columba livia muda sebesar 47,6% sedangkan kutu sayap lebih banyak ditemukan pada burung Columba livia dewasa sebesar 16,7%. Sebagian besar kutu ditemukan di daerah dada dan abdomen diikuti daerah kepala dan leher.
