Judul: Mempelajari flavor release perisa mint dan pemanis pada chewy candy dan chewing gum dengan metode Time-Intensity
Abstrak: Flavor release merupakan proses yang dinamis yang tidak cukup diukur dengan analisis sensorf konvensional yang hanya mengukur persepsi secara statis atau unipoint. Metode Time-Intensity (TI) merupakan metode analisis senson deskriptif yang dapat membenkan informasi secara simultan terhadap proses flavor release yang tetjadi. Dengan metode TI dapat terlacak waktu dimulainya flavor release, durasi, dan nilai intensitas komponen flavor yang tertepas. Data yang diperoleh berupa kurva dengan parameter-parameter yang terukur : Tstart (waktu dimulainya sensasi), Tmax (waktu intensitas sensasi mencapai maksimum), Tdec (waktu intensitas sensasi menurun dari intensitas maksimum), Tend (waktu berakhirnya sensasi yang dirasakan), Imax (nilai intensitas maksimum sensasi), dan Area Under Curve / AUC (luas area dl bawah kurva TI).

Judul: Studi Pengaruh Lama Penyimpanan, Waktu Pencampuran, dan Penambahan Solvent pada Key Component Terhadap Flavor Release pada Minuman Ringan di PT. Tudung Putra Putri Jaya
Abstrak: Flavor is a sensation that comes and is caused by chemical components of volatile or non-volatile, which originated from natural or synthetic, and occur during eating or drinking. Now, flavor more rapidly adopted by food and beverage industry in Indonesia, especially in beverage productss. The purpose of this study is to understand changes that occur in flavor release in the final product by mixing the flavor concentrat with a solvent that is affected by the concentration of key components, mixing time and length of storage using a flavour 10x more concentrated than the ready to use (RTU) flavor. The Comparison that used between flavor concentrat and solvent are 60:40, 70:30, 80:20, 90:10, and 100:0. Before mixing between flavor concentrat and solvent in some concentration will be conducted preliminary research to find optimum speed mixing using concentrat 10x that diluted until the concentration is equal to the RTU flavors that have been used in products already marketed. Flavor has been mixed to be tested storage for 5 weeks with weekly observation. Observations were using the Different Test with Triangle Test sensory that will prove whether formulations are different or not with the RTU flavor. Further development in industrial scale study will be conducted later.

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.
