Judul: Penggunaan Tepung Daun Jati (Tectona grandiss. Linn. f.) dalam Ransum Terhadap Kualitas Telur Puyuh Coturnix coturnix japonica.
Abstrak: Quail eggs are poultry products that can be used as an alternative of protein source by animal. Therefore, it was necessary to find a methode to improve production and the quality of quail eggs. This research was aimed to evaluate levels of utilization Tectona grandiss Linn. f. (tecton) leaves meal in ration to the quality of quail eggs (Coturnix coturnix japonica). The experiment used 180 head of quails aged 40 days and the quails were grouped according to the feeding treatments into four treatments and three replicates. The treatments were R0 (control), R1 (control with 3% tecton leaves meal), R2 (control with 6% tecton leaves meal), and R3 (control with 9% tecton leaves meal). The experiment was conducted using Completely Randomized Design (CRD). The parameters observed were egg quality. The result of this research showed that egg weight, albumen weight, yolk weight, egg shell weight, and haugh unit were significant difference (P>0.05), but shell thickness, and yolk color were not significant. Utilization of Tectona grandis Linn. f. leaves meal up to 6% can increased the quality of quails egg.

Judul: Produktivitas Puyuh Petelur Coturnix coturnix japonica yang diberi Tepung Daun Jati (Tectona grandis linn. f.) dalam Ransum.
Abstrak: This experiment was held at Slamet Quail Farm in Sukabumi, and Poultry Nutrition Laboratory, Faculty of Animal Science, Bogor Agricultural University, Bogor, from June to September, 2013. This research aimed to evaluated the effects of tecton leaf as addition in diet of quail. Laying quails aged 6 weeks and 180 heads had body weight average about 165.11±10.53 g were allowed in completely randomized design, that divided into four treatments with three replications. The treatments were classified into : basal diet (P0), basal diet + 3% tecton leaf meal (P1), basal diet + 6% tecton leaf meal (P2), basal diet + 9% tecton leaf meal (P3). Variables were feed intake, egg production, egg weight, egg mass, feed conversion ration and mortatilty. The result of this research showed that tecton leaf meal did not significantly affect on egg production, egg weight, egg mass, and feed conversion, but significantly decreased on feed intake (P<0.05). There was no mortality during this experiment. The addition of tecton leaf meal in ration decreased value of income overfeed cost. Tecton leaf meal supplementation was increased feed cost.

Judul: Konstruksi Persamaan Friedmann Alam Semesta Friedmann-Lemaitre-Robertson-Walker Termodifikasi Materi Gelap Superfluida
Abstrak: Kosmologi merupakan salah satu objek kajian dari teori relativitas umum. Salah satu model dalam kosmologi adalah model kosmologi Friedmann. Model kosmologi Friedmann dibangun berdasarkan asumsi bahwa materi dan energi terdistribusi secara homogen dan isotropik di alam semesta. Teori relativitas umum dapat dimodifikasi melalui pendekatan teori materi gelap superfluida (MGS). Persamaan medan Einstein untuk teori MGS dapat dirumuskan melalui prinsip aksi dengan memodifikasi Lagrangian pada aksi teori MGS. Selanjutnya dengan memilih metrik Friedmann-Lemaitre-Robertson-Walker (FLRW) datar dengan indeks kurvatur sama dengan nol, dapat dibangun suatu bentuk persamaan Friedmann yang dimodifikasi teori MGS.
