Judul: Studi Pembuatan Beras Analog Dari Berbagai Sumber Karbohidrat Menggunakan Teknologi Hot Extrusion
Abstrak: Analog rice is artificial rice product made from non rice and non wheat raw material by twin screw extruder. The objectives of this research were to formulate and to characterize rice analog made from a mixture of sorghum, corn, mocaf, maizena and aren sago. The method of rice analog production is hot extrusion by twin screw extruder. The research steps were formulation of analog rice, hedonic rating sensory evaluation to choose best sample, and characterization physico-chemical of best sample. The best two samples were choosen. They were analog rice made from sorghum flour 30% maizena 15% and aren sago 15% and analog rice made from mocaf 30% and maizena 30%. Both of best samples had higher carbohydrate and dietary fiber content than polished rice.

Judul: Development of Rice Analogues from White Corn, Sorghum and Soy and Its Potential as a Functional Food
Abstrak: Development of rice analogues is one of the alternatives to support diversification program. Rice analogues is an artificial rice, shaped like rice grains and can be made from non-rice flours. One of rice analogues raw materials is corn. Corn is second carbohydrate source after rice and contain high level protein (7-12%). The utilization of white corn pulut harapan variety that contain low amylose and lokal variety white corn that contain moderate level of amylose is aimed to produce rice analogues with not too pera and sticky texture. Sorghum and soy flour are also used to develop rice analogues as functional food. Sorghum contains high protein (11.61%) and high fiber (4.09%). Soy flour contains high protein (above 35%) and low glycemic index (GI = 21). Extrusion technology was used to produce rice analogues because of the process effectiveness and because it produces rice analogues that is similar to conventional rice. The purpose of this study were: (1) to characterize the raw materials, (2) to obtain the best rice analogues formulation, physicochemical properties, and sensory quality, (3) to produce rice analogues from white corn and sorghum with the addition of soy flour, and (4) to analyze the glycemic index of rice analogues. The study was conducted in several stages: (1) preparation and characterization of raw materials, (2) formulation of rice analogues from white corn and determination the best composition of the ingredients, (3) evaluation of glycemic index of selected rice analogues. The best rice analogues formula based on the sensory test was composed of pulut and local corn (4.3% : 65.7%) and sago starch 30%. Its containing 5.35% dietary fiber so it can be used as a food source of dietary fiber. Rice analogues from white corn and sorghum raw material and soy flour potential as a functional food because were resistant starch (2.59% - 3.31%), total phenol (0.18 – 0.25 mg GAE/g sampel) and it can be used as a food source of dietary fiber (5.35% – 6.14%). Rice analogues from white corn raw material (JP) and white corn and soy flour (JPK) raw materials were selected for glycemic index test. The analysis results of JP and JPK formulation respectively were resistant starch 2.59% and 3.28%, total phenol 0.24 mg GAE/g sampel and 0.25 mg GAE/g sampel, total dietary fiber 5.35% and 5.84%. Glycemic index of JP rice analogues was 69 while JPK rice analogues was 50.

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.
