Judul: Identification of Cryptosporidium sp. in Long-tailed Macaque (Macaca fascicularis) at Primate Research Center of IPB University
Abstrak: Monyet ekor panjang (Macaca fascicularis) merupakan hewan yang rentan mengalami kepunahan dan terinfeksi parasit Cryptosporidium sp. Selain menginfeksi M. fascicularis, Cryptosporidium sp. juga menginfeksi manusia sehingga berpotensi menimbulkan penyakit zoonosis. Oleh karena itu, penelitian ini perlu dilakukan untuk mengidentifikasi keberadaan Cryptosporidium sp. pada M. fascicularis. penelitian ini bertujuan memeriksa keberadaan Cryptosporidium sp. pada feses M. fascicularis di penangkaran ex-situ PSSP IPB. Pemeriksaan sampel feses dengan metode flotasi(35) dan Pewarnaan Ziehl Neelsen (69). Hasil pemeriksaan ini menunjukkan bahwa tingkat infeksi dari Cryptosporidium sp. pada M. fascicularis dewasa dengan metode flotasi dan pewarnaan ZIehl Neelsen sebanyak 25,71% dan 24,64%. Tingkat infeksi Cryptosporidium sp. pada M. fascicularis muda dengan metode pewarnaan Ziehl Neelsen sebanyak 27,27%. Hal ini menunjukkan bahwa M. fascicularis muda lebih mudah terinfeksi Cryptosporidium sp., Long-tailed monkey (Macaca fascicularis) is an animal that is prone to extinction and is infected with the parasite Cryptosporidium sp. Besides infecting M. fascicularis, Cryptosporidium sp. It also infects humans and has the potential to cause zoonotic diseases. Therefore, this research needs to be done to identify the presence of Cryptosporidium sp. on M fascicularis. This study aims to examine the presence of Cryptosporidium sp. in feces of M. fascicularis incaptivity of ex situ PSSP IPB. Examination of stool samples by flotation method (35) and Ziehl Neelsen staining (69). The results of this examination indicate that the infection rate of Cryptosporidium sp. on M. fascicularis adultby flotation method and Ziehl Neelsen staining were 25.71% and 24.64%, respectively. The infection rate of Cryptosporidium sp. in M. fascicularis youngwith the Ziehl Neelsen staining method as much as 27.27%. This indicates that M. fascicularis are youngmore easily infected with Cryptosporidium sp.

Judul: Identifications of Gastrointestinal Parasites in Long-Tailed Monkey (Macaca fascicularis) at The Primate Research Center of IPB  University
Abstrak: Infeksi parasit merupakan salah satu masalah yang sering ditemukan pada satwa primata, termasuk monyet ekor panjang (Macaca fascicularis). Infeksi parasit pada saluran pencernaan perlu diwaspadai karena dapat mengganggu kesehatan monyet ekor panjang di penangkaran dan berpotensi menjadi sumber penyakit zoonotik yang dapat menyebar kepada manusia. Penelitian ini bertujuan mengidentifikasi parasit gastrointestinal pada feses monyet ekor panjang di Pusat Studi Satwa Primata (PSSP) IPB. Sebanyak 69 sampel feses monyet ekor panjang diperiksa menggunakan metode natif dan pewarnaan trichrome untuk mengidentifikasi parasit. Hasil pemeriksaan menunjukkan bahwa terdapat Entamoeba spp., E. polecki, E. coli, E. histolytica/E. dispar, Endolimax nana, Balantidium coli, Iodamoeba bütschlii, Giardia sp., dan Ancylostomatidae, yang diduga bersumber dari air yang digunakan di PSSP IPB. Perubahan konsistensi feses diduga diakibatkan faktor selain infeksi parasit., Parasitic infection is a problem that is often found in nonhuman primates, including the long-tailed monkey (Macaca fascicularis). Parasitic infections in the digestive tract need to be concerned because they can interfere with the well-being of long-tailed monkeys in captivity and have the potential to become a source of zoonotic diseases that can spread to humans. This study aims to identify gastrointestinal parasites in long-tailed monkey feces at the Primate Research Center of IPB University. A total of 69 samples of long-tailed monkey feces were examined using native method and trichrome staining to identify parasites. The results showed that there were Entamoeba spp., E. polecki, E. coli, E. histolytica/E. dispar, Endolimax nana, Balantidium coli, Iodamoeba bütschlii, Giardia sp., and Ancylostomatidae, allegedly derived from the water in PSSP IPB. Change in stool consistency is assumed to be due to factors other than parasitic infection.

Judul: Rancang Bangun Elemen Pemanas Bahan Bakar Minyak Nyamplung Untuk Motor Bakar Diesel dengan Memanfaatkan Panas Gas Buang
Abstrak: Tamanu oil is one of biosolar substituter as diesel engine fuel. High viscosity of tamanu oil becomes main obstacle in direct using of tamanu oil as diesel engine fuel. Heater element is made to decrease tamanu oil viscosity. Heater element is benefitted high temperature of diesel engine exhaust gas as reheating source. Optimum temperature which is needed to reduce tamanu oil viscosity of 3-5 cSt is 110 Celcius degree (biosolar viscosity of 30oC is 5-7 cSt). IV design of element heater has optimum tamanu oil reheating. There are four kind of tamanu oil that has different treatment. degumming neutralization (N4) tamanu oil has best quality with the lowest viscosity of 30cSt in 30oC. Tamanu oil (N4) usage as fuel occur reduction power of 12.26 %, torsion of 9.59 %, power maximum of diesel engine is 5.39 kW and maximum torsion of 123.74 Nm. Maximum power of diesel engine using biosolar is 5.99 kW and maximum torsion of 144.53 Nm. But then, tamanu oil can replace biosolar (fossil energy), without made as biodiesel first and mixed with biosolar.
