Judul: Optimasi Sebaran Panas Pada Ruang Sterilisasi Jamur Tiram Putih Menggunakan Satu Pipa Konveksi
Abstrak: It has been produced for the temperature distribution inside the sterilization process oyster mushroom in drum using a pipe convection. Fuel used for the process is rice husk. Sterilization itself aims to kill bacteria and other unwanted fungi on baglog. Sterilization is done with the traditional way of steaming baglog drums arranged in four rows to the top, with a long steaming 6 hours. Convection pipes built at the drums. Steaming is done by varying the diameter of the pipe convection is 6 cm and 8 cm with two replications of data retrieval. From the experimental results obtained that the use of convection pipe 8 cm better than the convection pipe 6 cm. It is shown from the number of fungal contamination on the pipe less than 8 cm convection convection pipe 6 cm. The experimental results corroborate the results of previous studies carried out using computer simulations with finite difference method.

Abstrak: Sterilization of oyster mushroom with three and five variation of convection pipe has been sucsessfully done, that used rice hull hearth. Sterilization process of oyster mushroom is very influence at baglog and mushroom result. Functional group had been got of sterilization process at three and five pipe that is at micelyum baglog and mushroom contain C-O, C-H, C=O and O-H. Spring constant at micelyum baglog for three pipe in a series are 779 Nm-1, 470 Nm-1, 1110 Nm-1 and 564 Nm-1 whereas vibrational wave number are 1365 cm-1, 2924 cm-1, 1659 cm-1, and 3371 cm-1. Spring constant at micelyum baglog for five pipe in a series are 751 Nm-1, 470 Nm-1, 1080 Nm-1, 501 Nm-1 whereas vibrational wave number are 1366 cm-1, 2924 cm-1, 1636 cm-1 and 3371 cm-1. Spring constant at mushroom for three pipe in a series are 821 Nm-1, 470 Nm-1, 1110 Nm-1 and 591 Nm-1 whereas vibrational wave number are 1373 cm-1, 2923 cm-1, 1658 cm-1 and 3371 cm-1. Spring constant at mushroom for five pipe in a series are 803 Nm-1, 470 Nm-1, 1110 Nm-1 and 547 Nm-1 whereas vibrational wave number are 1365 cm-1, 2924 cm-1,1659 cm- 1 and 3371 cm-1.

Judul: Berat Badan Dan Morfometrik Leopard Gecko (Eublepharis Macularius) Pada Berbagai Umur
Abstrak: Leopard gecko (Eublepharis macularius) adalah jenis tokek yang hidup di permukaan tanah dan aktif saat fajar dan senja. Studi morfometrik dalam leopard gecko masih terbatas. Tujuan dari penelitian ini adalah untuk mengukur dan membandingkan berat badan dan morfometrik leopard gecko dari berbagai umur. Sebanyak 14 ekor leopard gecko (3 ekor jantan dan 11 ekor betina) dikelompokkan menjadi empat kelompok: 0-6 bulan, 7-12 bulan, 13-18 bulan, dan 19-24 bulan. Pengukuran dilakukan setiap bulan selama tiga bulan sehingga hewan dapat ditimbang dan diukur lebih dari sekali. Selama 90 hari pascatetas, pengukuran berat dan panjang dilakukan setiap hari, dua hari, atau setiap minggu tergantung dengan tingkat pertumbuhan. Hasil penelitian menunjukkan bahwa kelompok umur 0-6 bulan memiliki berat badan 10.69±5.68 g dan total panjang 12.79±3.68 cm; 7-12 bulan memiliki berat badan 16.57±4.52 g dan total panjang 16.7±1.23 cm; 13-18 bulan memiliki berat badan 21.12±3.13 g dan total panjang 19.4±1.15 cm; dan 19-24 bulan memiliki berat badan 27.9±1.53 g dan total panjang 20.8±1.51 cm. Dapat disimpulkan pada leopard gecko kelompok umur 0- 6 bulan memiliki pertumbuhan yang lebih bervariasi pada berat badan, panjang kepala, panjang kaki belakang, dan panjang ekor dibandingkan dengan yang lain.
