Judul: Potensi Sorgum Sebagai Pengganti Jagung Dengan Penambahan Tepung Duckweed (Lemna Minor) Terhadap Kualitas Dan Nilai
Abstrak: Penggunaan sorgum dalam pakan puyuh petelur harus diimbangi dengan pemberian sumber pakan yang mengandung karoten salah satu tanaman yang berpotensi sebagai sumber karotenoid adalah Lemna minor (duckweed). Penelitian ini menggunakan 5 taraf perlakuan, P0 = ransum control jagung, P1 = ransum control sorgum, P2 = ransum sorgum + 1.5% tepung duckweed, P3 = ransum sorgum + 3% tepung duckweed, dan P4 = ransum sorgum + 4.5% tepung duckweed. Penelitian ini menggunakan uji deskriptif dengan objek observasi 32 ekor puyuh berumur 44 hari. Peubah yang diamati adalah skor warna kuning telur, kualitas telur seperti bobot telur, bobot kuning, bobot putih, tebal kerabang, serta pengukuran nilai MDA. Hasil penelitian menunjukkan bahwa sorgum dapat dijadikan sebagai sumber energi untuk pakan puyuh petelur dan dapat meningkatkan kualitas kuning telur puyuh jika diimbangi dengan pemberian tepung duckweed. Penggunaan tepung duckweed dengan taraf 1.5% belum mampu menandingi skor kuning telur jika dibandingkan dengan ransum jagung, sedangkan taraf 3% dan 4.5% mampu menandingi dan melebihi. Penyerapan vitamin A yang berasal dari beta karoten tepung duckweed juga dapat terlihat dari nilai MDA, perlakuan dengan penambahan tepung duckweed dapat menekan nilai MDA jika dibandingkan dengan P0 dan P1.

Judul: Substitusi Jagung dengan Sorgum yang Ditambahkan Tepung Daun Singkong terhadap Kualitas Telur Puyuh
Abstrak: Sorgum is an energy sources which is highly potential to develop. It has low carotene level, so it has to be balanced by adding carotene in the feed meal. Cassava leaf meal is a kind of forages which has high carotene level 154mg kg-1. This research aimed to study the effect of White Sorgum as corn subtitution with cassava leaves meal combination on the quality and vitamin A of Japanese Quail Egg. This observations used completely randomized design with five treatment and three repetition (10 eggs/repetition). The treatments are control (P1), 50% sorgum + cassava leaves meal 0% (P2), 50% sorgum + cassava leaves meal 1.5% (P3), 50% sorgum + cassava leaves meal 3% (P4), 50% sorgum + cassava leaves meal 4.5% (P5). It is concluded that sorgum and cassava leafs meal were able to increase egg weight, yolk color, albumin weight, haugh unit, and vitamin A level.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
