Judul: Perbedaan Ukuran Screen dan Die Terhadap Kualitas Fisik Pelet dan Performa Tikus Putih (Rattus norvegicus)
Abstrak: The purpose of study was to obtain pellets feed for White Rats (Rattus norvegicus) on growth phase form which has the best physical quality of pellets and rats performance. The research was carried out using factorial randomized complete design 2 x 2. The first factor was screen size (3 mm and 5 mm) and the second factor was die size (4 mm and 16 mm). The treatments were P1 (screen 3 mm die 4 mm), P2 (screen 3 mm die 16 mm), P3 (screen 5 mm die 4 mm), P4 (screen 5 mm die 16 mm). The study on physical quality of pellets was performed in four replications for each treatment. Parameters measured were durability, bulk density, density compacted and true density. The study on in vivo trial on rats was conducted in five replications for each treatment. Parameters measured were body weight gain, consumption, dry matter digestibility, and organic matter digestibility. Data were analyzed using Analysis of variance and Duncan multiple range test. The result showed that there was an interaction effect between screen and die size on durability (P<0.01) and true density (P<0.01) of pellets, and body weight gain (P<0.05) and consumption (P<0.01) of the rats. It was concluded that pellet P1 has the best physical quality and P2 showed the best performance of rats.

Judul: Performance of White Mouse (Mus musculus) on Use of Different Litters
Abstrak: Manajemen pemeliharaan pada aspek perkandangan merupakan salah satu hal yang penting, karena dengan kondisi kandang yang baik dapat memberikan kenyamanan terhadap mencit sehingga produktivitas dan performa menjadi meningkat. Salah satu alternatif pada aspek perkandangan yang dapat diupayakan untuk meningkatkan produktivitas dan performa mencit yang baik yaitu pemakaian jenis alas kandang. Penelitian ini bertujuan mengetahui pengaruh perbedaan penggunaan alas media yang berbeda terhadap pertambahan bobot badan, jumlah konsumsi air, jumlah anak serta mortalitas pada mencit putih. Penelitian ini menggunakan rancangan acak lengkap dengan tiga perlakuan dan empat ulangan. Hasil penelitian menunjukkan bahwa perlakuan tidak berpengaruh nyata terhadap pertambahan bobot badan, jumlah konsumsi air, jumlah anak serta mortalitas. Pertambahan bobot badan mencit putih tertinggi pada perlakuan alas sekam (P1) sebesar 20,54 ± 3,83 g, jumlah konsumsi air mencit putih tertinggi pada perlakuan alas sekam (P1) sebesar 26,85 ± 1,15 ml, jumlah anak tertinggi mencit putih pada perlakuan alas zeolit (P2) sebesar 6,50 ± 2,34 ekor, dan mortalitas tertinggi pada perlakuan alas kertas (P3) sebesar 0,25 ± 0,20 ekor., Maintenance management in the housing aspect is one of the important things, because good cage conditions can provide comfort for mice so that productivity and performance will increase. One alternative in the cage aspect that can be sought to increase the productivity and good performance of mice is the use of a type of cage mat. This study aims to determine the effect of differences in the use of different litters on body weight gain, amount of water consumption, number of children and mortality in mice. This study used a completely randomized design with three treatments and four replications. The results showed that the treatment had no significant effect on body weight gain, total water consumption, number of children and mortality. The highest weight gain of white mouse was in the husk base treatment (P1) of 20.54 ± 3.83 g, the highest amount of water consumption of white mouse was in the husk base treatment (P1) of 26.85 ± 1.15 ml, the highest number of children was mice in the treatment zeolite base (P2) was 6.50 ± 2.34, and the highest mortality was in the paper mat treatment (P3) was 0.25 ± 0.20.

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.
