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: Karakteristik Anatomi Skelet Kepala Badak Jawa (Rhinoceros sondaicus)
Abstrak: Badak jawa (Rhinoceros sondaicus) adalah spesies badak bercula satu yang hidup di Taman Nasional Ujung Kulon (TNUK), Indonesia. Tujuan penelitian ini adalah mempelajari karakteristik anatomi skelet kepala badak jawa yang dikaitkan dengan perilakunya. Penelitian dilakukan dengan mengamati struktur dua buah skelet kepala badak jawa jantan. Skelet kepala diukur dimensi dan volume cavum cranii, dipelajari struktur dan formula giginya, didokumentasi, serta dipindai dengan CT scan. Penamaan unsur-unsur anatomi berdasarkan Nomina Anatomica Veterinaria 2015 dan kemudian struktur anatominya dibandingkan dengan pustaka pada hewan-hewan lain. Secara umum skelet kepala badak jawa memiliki pars splanchnocranii yang sangat berkembang, pars neurocranii yang meninggi ke posterior, dan atap kepala yang konkaf dan tebal disertai simus-sinus di profundal-nya. Skelet kepala badak jawa memiliki permukaan yang kasar pada os incisivum, os nasale, os frontale, dan os maxilla serta memiliki bungkul di os lacrimale dan rigi di os zygomaticum. Selain itu, hewan ini memiliki crista nuchae yang terletak di dorsoanterior condylus occipitalis dan squama occipitalis yang luas dengan persendian occipitoatlantis yang luas di sisi dorsal-nya. Arcus zygomaticus dan fossa temporalis pada hewan ini luas dan berkembang serta angulus mandibularis dan permukaan persendian rahang bawah pada os temporale yang luas. Bagian-bagian tersebut beradaptasi untuk mendukung perilaku badak jawa dalam mencari makan dan bertahan hidup….
