Judul: Proses Pengeringan Sohun Dengan Menggunakan Oven Melalui Pemanasan Bertahap
Abstrak: Vermicelli is a type of noodle that is made from pure starch of sagoo or mung bean. Vermicelli has an appearance like a string, spongy and slick texture, also transparent. On vermicelli making process in small food industry, the drying technique is still using the natural technique which is with sun light. The usage of solar will cause inconsistency in quality of vermicelli and requires many labors and a big lot. These reasons encourage to conduct a research of vermicelli drying process with oven dryer through gradual drying. There were three heating treatments, which were A) 65oC – 10 minutes, 100oC – 10 minutes, and 140oC – 5 minutes, B) 80oC – 10 minutes, 100oC – 10 minutes, and 130oC – 5 minutes, C) 80oC – 15 minutes and 140oC – 10 minutes and the recommended drying treatment was the drying that used for sample B, which was drying technique with temperature 80oC – 10 minutes, 100oC – 10 minutes, dan 130oC – 5 minutes. The vermicelli that was produced by this treatment had characteristics water content 13.09%, cooking loss 11.67%, water absorption 74.56%, elongation 198%, L color 58.03, a -2.58, and b 9.21% which had the slightest differences on water content, cooking loss and elongation analysis with a vermicelli that had been produced by a manufacture (control). The difference between cost for solar drying and cost for oven drying was Rp 24,720,000 in producing 80 tons of vermicelli in a month. Oven drying can reduce the operational cost to 33% compared to solar drying.

Judul: Optimasi Proses Pengeringan Sohun CV Panca Jaya Dengan Menggunakan Pengering Rak
Abstrak: Sohun is a non-wheat noodle product that is made with a typical shape from starch base material. Sohun can be categorized based on the used flour such as mung beans, sago, sugar palm, etc. CV Panca Jaya is one of the medium enterprises which produced sohun since 1984. Kembang Matahari® is a brand name of it. Drying process in this factory is still using sunlight as an energy system. It requires a lot of human resources and also a huge area, so a rising inflation will give direct impacts on the increasing components of cost production, especially on labor wages significantly. This study has done a simulation of sohun production process using cabinet dryer with software RSM (Response Surface Methodology). The result of the optimization process showed that cabinet drying gave similar product with sun drying

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.
