Judul: Quality of Eggs Based on Different Age of Chickens from Yong's Farm, Seremban, Malaysia
Abstrak: This study aimed to determine the quality of eggs from different ages of chickens from Yong’s Farm, Seremban, Malaysia. The method used was 60 eggs were collected from three of different ages of chicken; 25 (n=20 eggs), 35 (n=20 eggs) and 58 weeks old (n=20 eggs). The variables included egg weight, shell thickness, yolk color, yolk index, albumen index and Haugh unit. The results showed the highest egg weight was recorded with 58 weeks old chicken. The egg shell thickness found at week 25 week (0,455 ± 0,08 mm), 35 weeks (0,495 ± 0,08 mm) and 58 weeks (0,475 ± 0,08 mm). Yolk color was at the highest mean of.12,6 ± 0,68 (25 weeks) while on week 35 and 58 it ranges between 5,45 ± 0,51 and 5,55 ± 0,51. The yolk index was recorded on week 25 and no specific trends were observed and the yolk index was not significant between 35 and 58 weeks of age. Albumen index was highest at week 25 were (0,129 ± 0,0), week 35 (0,113 ± 0,03) and week 58 (0,088 ± 0,02). The highest HU was recorded at week 25 (94,81 ± 5,33) and decreased to (90,52 ± 6,64) at week 35 and (81,95 ± 6,24) at week 58. It can be concluded that chicken influences both exterior and interior quality, except the yolk color with the quality of eggs decreasing as the age increases.

Judul: External Quality of Hatching Eggs of Ayam  Kampung Unggul Balitbangtan (KUB) from Different Hen Ages
Abstrak: Peningkatan umur ayam dapat menyebabkan warna kerabang telur semakin pudar, kerabang telur semakin tipis dan bobot telur semakin berat sehingga menurunkan kualitas telur yang dihasilkan. Tujuan penelitian adalah menganalisis perbedaan kualitas eksternal telur tetas ayam KUB dari induk parent stock (PS) yang berumur 40 dan 60 minggu yang berasal dari pembibitan ayam Taman Teknologi Pertanian (TTP), Cigombong, Bogor, Jawa Barat. Kualitas eksternal telur yang diamati meliputi bobot, bentuk telur, indeks bentuk telur, bobot kerabang, kebersihan kerabang, warna kerabang dan tebal kerabang telur. Jumlah telur yang diamati sebanyak 30 butir setiap kelompok umur. Data yang diperoleh dianalisis dengan statistik deskriptif yaitu pada kebersihan kerabang, bentuk telur, warna kerabang, dan kehalusan kerabang. Uji T (T-Test) independen digunakan untuk menganalisis data bobot telur, indeks bentuk telur, bobot kerabang dan ketebalan kerabang. Hasil penelitian menunjukan perbedaan yang nyata (P<0,05) pada bobot telur, indeks bentuk telur, bobot kerabang dan ketebalan kerabang. Penelitian ini menduga faktor lingkungan kandang, dan juga kesehatan ayam juga menentukan kualitas eksternal eksternal telur., The increasing of hen age may reduce the hatching egg color and shell thickness, and also increase the hatching egg weight. The aim of the study was to analyze the differences in the external quality of hatching eggs from 40 (P1) and 60 weeks of age (P2) of KUB chicken parent stock produced by chicken breeding farm TTP Cigombong, Bogor, West Java. The external hatching egg quality observed were included off the weight, egg shape, egg shape index, shell weight, shell cleanliness, shell color and egg shell thickness. There were 30 hatching eggs which were observed in this study for each age of group. The shell cleanliness, egg shape, shell color and shell smoothness were analyzed descriptively. The egg weight, egg shape index, shell weight and shell thickness was analyzed by T test (T-Test) independent. There were significantly differences (P< 0.05) in the egg weight, shell weight, and hatching egg shell thickness between hatching eggs produced by hens aged 40 (P1) and 60 weeks (P2). This study predicts that the environmental factor, and also chicken health might influence the external quality of chicken hatching egg.

Judul: Uji coba kultur in vifro untuk perbanyakan tabat barito (Ficus deltoidea Jack)
Abstrak: Tumbuh-tumbuhan yang d i j a d i i bahan bak- obat, khususnya obat tradisional mencapai lebih dari 100 jenis dan 74% diantaranya merupakan tumbuhan liar yang hidup di hutan. Tabat Barito (Ficlis deltoidea Jack.) adalah salah satu tumbuhan hutan yang digunakan sebagai obat. Sebagian besar bahan baku obat Tabat Barito masih berasal dari panen secara langsung di alanl. Sementara itu jika laju pelnanenan lebih cepat dibandiigkan dengan kemampuan alam untuk memulihkan populasinya maka proses kepunahan tidak dapat dielakkan. Untuk itu perlu dilakukan pembudidayaan baik in-situ maupun ex-situ dengan cara generatif dan vegetatif. Pengembangbiakan secara vegetatif dengan cara mikropropagasi melalui kultur in vitro dapat digunakan sebagai salah satu alternatif perbanyakan untuk menghasilkan bahan tanaman relatif lebih cepat.
