Judul: Formulasi dan Analisis Nilai Gizi Produk Mi Berbasis Sorgum (Sorghum Bicolor (L.) Moench.)
Abstrak: Sorghum as cerealia has many advantages over rice, including phenolic compound that have health potential in human body. This grain has good adaptation to dry and tropical climate that is suitable to grow in Indonesia. The objective of this research was to determine the best formula based on organoleptic (colour, taste, and texture), mineral, dietary fiber, and antioxidant activity analysis results. The initial stage of this research was to find the best formula from extrusion processing. The second stage is organoleptic test by hedonic rating and ranking. Mineral analysis (Ca, Fe, and Zn) by AAS method, dietary fiber analysis, and antioxidant by DPPH method were the last stage of this research. The variables that differentiate between formulas are ratio of sorghum to water (60%, 70% and 80%), temperature of starch gelatinitation (80oC, 90oC, and 100oC), and also frying time (1 minute and 2 minutes). Formulas with 60% ratio of sorghum (milled and unmilled sorghum) have the best quality from extrusion processing. Formula with 60% ratio unmilled sorghum at 1 minute frying has the highest rank from organoleptic test. At 2 minutes frying, formula with 60% ratio milled sorghum has the highest rank. Unmilled sorgum noodle have high dietary fiber, 33% compliance rate of nutrient adequacy, and high amount of Fe and Zn. Milled sorgum noodle also have 28% compliance rate nutrient adequacy of dietary fiber. Antioxidant activity from unmilled sorgum noodle (1.98 ppm AEAC/g product) higher than milled sorgum noodle (1.18 ppm AEAC/g product).

Judul: Optimasi Formula Flakes Berbasis Sorgum (Sorghum Bicolor L.) Dan Sagu (Metroxylon Sp.).
Abstrak: Indonesia memiliki berbagai jenis komoditas hasil pertanian, di antaranya sorgum dan sagu. Salah satu produk olahan yang dapat dibuat dari sorgum dan sagu adalah flakes. Tujuan dari penelitian ini adalah melakukan optimasi formula flakes berdasarkan respon tekstur (hardness, total work), pati tercerna, warna (lightness, hue), serta sifat sensori yang diterima oleh anak-anak. Proses optimasi formula yang digunakan pada penelitian ini adalah metode Mixture Design D-Optimal dari program Design Expert 7.0®. Tiga faktor formula yang digunakan antara lain sorgum, sagu, dan maltodekstrin. Hasil penelitian ini menghasilkan formula terpilih dengan komposisi 3.87% sorgum, 29.68% sagu, dan 17.25% maltodekstrin dengan nilai desirability sebesar 0.839. Hasil verifikasi menunjukkan formula terpilih memiliki hardness sebesar 1046 g, total work sebesar 2.26 mJ, pati tercerna sebesar 64.84 g/100g, lightness sebesar 49.14, dan hue sebesar 47.98º. Hasil uji subyektif menunjukkan formula terpilih sudah dapat diterima secara sensori pada semua paramater sensori (warna, aroma, tekstur, rasa). Hasil uji kimia flakes menunjukkan bahwa kadar air, kadar abu, kadar lemak, kadar protein, dan kadar karbohidrat masing-masing 2.86%, 0.55%, 5.40%, 2.06%, 89.14%.

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.
