Judul: Egg Quality Appearance of Medium Type Layer Hens in Different Feeding Time and Protein Levels.
Abstrak: Domesticated fowls, in particular the layer hens, play an important as one of the egg and meat producing fowls. The primary commodity produced by these layers composes highly nutritional value and are considered as a highly demanding commodity. This research was conducted at Housing-B of the Poultry Field Laboratory, Faculty of Animal Production, Bogor Agricultural University. The research used 162 hens of Isa Brown medium type layer, 20 weeks old which were raised at individual cages constructed completely with feeder and drinker. The aim of this research was to observe the egg quality of the Isa Brown medium type layer assigned to different feeding times and protein levels. The research used 3x3 Factorial Completely Randomized Design with three feeding time (morning at 08.00, afternoon at 18:00, and dawn at 04.00); and three different protein levels (12, 15 and 18%), treatment consisted of three replicates. Each replicate consisted of six birds. Ration was fJrmuiated iso-caloric energy (2650 Kcal/kg). The variables observed were external egg quality which consist of egg weight, entirety, translucency, egg index, shell thickness, and specific gravity; and internal egg quality which consist of Hallgh Unit, egg yolk color, and yolk and albumen weight. The result showed that here was not effect of interaction between time of feeding and protein level on the observed parameters Feeding time had significant effect on shell thickness. The protein level treatml:uts showed significantly (p<=0.05)on egg weight, shell thickness, egg yolk color, yolk and albumen weight. Based on the cleaness entirely, almost all of the eggs colected were considered clean and undamaged. Key words: feeding time, protein level, egg quality, layer medium hens.

Judul: Organic Mineral Mixed Suplementation in Feed on Isa Brown Laying Hens Performance and Quality 90-97 Weeks
Abstrak: Penelitian ini bertujuan mengevaluasi suplementasi campuran mineral organik dalam pakan pada ayam petelur . Penelitian menggunakan 1444 ekor ayam. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 2 perlakuan dan 11 ulangan. Perlakuan yang digunakan adalah T0 = pakan komersial, dan T1 = pakan komersil + campuran mineral organik. Parameter yang diamati terdiri dari warna kerabang, kekuatan kerabang, ketebalan kerabang, haugh unit, hen day production, konsumsi pakan, bobot telur, dan konversi pakan. Data dianalisis menggunakan uji T. Hasil penelitian berpengaruh nyata meningkatkan hen day production, konversi pakan, konsumsi pakan, warna kerabang, ketebalan kerabang, dan kekuatan kerabang (P <0,05), namun tidak berpengaruh pada bobot telur dan haugh unit (P >0,05). Penerapan suplementasi campuran mineral organik dapat meningkatkan hen day production, konsumsi pakan, konversi pakan, kekuatan kerabang, warna, ketebalan kerabang telur ayam petelur strain Isa Brown, namun belum mampu meningkatkan haugh unit dan bobot telur., This study was aimed to evaluate supplementation of organic mineral mix in feed for Isa Brown hens. The study used 1444 chickens. This study used a completely randomized design (RAL) with 2 treatments and 11 replications. The treatments used were T0 = commercial feed and T1 = commercial feed + organic mineral mixture. Parameters observed consisted of shell color, shell strength, shell thickness, haugh unit, hen day production, feed consumption, egg weight, and feed conversion. Data were analyzed using T test. The results showed that significantly improved hen day production, feed conversion, feed consumption, shell color, shell thickness, and shell strength (P <0,05), but had no effect on egg weight and haugh unit (P >0,05). The application of organic mineral mixture supplementation can increase hen day production, feed consumption, feed conversion, shell strength, color, egg shell thickness of laying hens strain Isa Brown, but has not been able to increase the haugh unit and egg weight.

Abstrak: Perkembangan kota Jakarta dari waktu ke waktu sangatlah cepat, sehingga menyebabkan kota-kota tua banyak yang tergusur untuk dijadikan daerah baru yang lebih modern. Apabila hal tersebut tidak ditanggulangi secara dini maka keberadaan Kota Lama Jakarta akan hilang. Hal inilah yang melatar belakang untuk dilakukan tindakan perlindungan dan revitalisasi kawasan bersejarah Sunda Kalapa.
