Judul: Perangkat Sentrifugasi Tenaga Tangan dari Bahan Katun untuk Menilai Hematokrit Domba Bunting
Abstrak: Pemeriksaan nilai hematokrit adalah parameter yang dapat digunakan untuk membantu dalam menegakkan diagnosa. Sentrifuse adalah alat yang digunakan untuk memisahkan komponen penyusun darah berdasarkan sifat-sifat zat penyusunnya. Penelitian ini bertujuan untuk membuat perangkat sentrifugal bertenaga tangan menggunakan bahan katun untuk menilai hematokrit pada domba bunting. Kain katun dipotong membentuk lingkaran setelah diresapi dengan lilin batik sebelumnya. Pada bagian tengah piringan kain katun dimasukkan benang rajut dan setiap ujung tali diikatkan ke handler. Kecepatan rata-rata sentrifugasi yang dihasilkan oleh Katunfuge lebih besar dari 2000 rpm, 99% efektif untuk memisahkan komponen darah dalam waktu 15 menit melalui 14x tarikan tangan. Nilai hematokrit domba bunting bunting lebih rendah (33 ± 4.1) dibandingkan dengan domba yang tidak bunting (38,5 ± 3,4%) dan Katunfuge berpotensi digunakan untuk menilai hematokrit hewan lain.

Judul: Development of Cotton-based Microfluide  Device for Assessment of Hematocrit in Pregnant Ewes, Dehydration and  Septicaemia Models
Abstrak: Perubahan metabolik dapat disebabkan oleh berbagai kondisi dan fase fisiologis, seperti perubahan profil darah pada kondisi kebuntingan atau kondisi patologis lainnya seperti septicaemia. Pemeriksaan darah lengkap biasa dilakukan untuk mengetahui status kesehatan hewan atau untuk mendukung diagnosis. Salah satu pemeriksaan darah adalah pemeriksaan kadar hematokrit. Pengembangan alat mikrofluida untuk menilai kadar hematokrit pada penelitian ini dikembangkan menggunakan kain katun berdasarkan panjang rembesan darah. Sebanyak 3 kelompok darah domba (jantan n=2, bunting n=2, dan tidak bunting n=2) dimanipulasi menjadi 3 kondisi yaitu pengenceran, normal, dan peningkatan konsentrasi, kemudian panjang rembesan dan kadar hematokrit. diukur. Pengaruh penyimpanan darah terhadap kadar hematokrit juga diuji dengan menyimpan darah pada hari ke 0, 2, 4, dan 7. Hasil penelitian menunjukkan bahwa terdapat perbedaan panjang rembesan pada masing-masing sampel darah. Jarak terjauh diperoleh pada kondisi pengenceran. Sementara, jarak terpendek diperoleh pada peningkatan konsentrasi. Pengaruh penyimpanan darah terhadap kadar hematokrit menunjukkan penurunan pada hari ke-7 pada pengukuran dengan menggunakan alat mikofluida di semua sampel darah dan hari ke-4 pada tabung mikrokapiler hematokrit pada sampel darah jantan dan tidak bunting. Sementara, pada sampel darah bunting, kadar hematokrit cenderung stabil. Pengembangan alat mikofluida berbasis kain katun mampu mengukur nilai kadar hematokrit sehingga menjadi bahan pertimbangan sebagai alat diagnostik untuk menilai hematokrit., Metabolic changes can be caused by various physiological conditions and phases, such as changes in blood profile in pregnancy or other pathological conditions such as septicemia. Complete blood count is usually done to determine the health status of the animal or to support the diagnosis. One of the blood tests is the examination of hematocrit levels. The development of a microfluidic device to assess the hematocrit level in this research was developed using cotton cloth based on the wicking length of blood. A total of 3 groups of sheep's blood (male n=2, pregnant n=2, and not pregnant n=2) were manipulate in to 3 conditions, namely dilution, normal, and increasing concentration, and then the wicking length and hematocrite level measured. The effect of blood storage on hematocrit levels was also tested by storing blood on days 0, 2, 4, and 7. The results showed that there were differences in the length of wicking in each blood sample. The longest was obtained in the dilution condition. However, the shortest was obtained at increasing concentration. The effect of blood storage on hematocrit levels showed a decrease in day 7 on measured by using the microfluidic device in all blood samples and day 4 on microcapillary hematocrit tubes in male and non-pregnant blood samples. However, in pregnant blood samples, hematocrit levels tended to be stable. The development of a microfluidic device based on cotton cloth is able to measure the value of the hematocrit level so that it becomes a consideration as a diagnostic tool to assess the hematocrit.

Judul: Lejeuneaceae Subfamily Ptychanthoideae (Hepaticae) in  West Java
Abstrak: Subfamily Ptychanthoideae of the family Lejeuneaceae (Hepaticae) in West Java is still poorly known. Publications on this subfamily are out of dated and written in the 19th or early of 20th century. The last taxonomic treatment of Ptychanthoideae of West Java was in 1933, many species names have changed since then. Studies on Ptychanthoideae of West Java are urgently needed. Studies on the Ptychanthoideae were based on the specimens collected from West Java. A total number of 361 of specimens deposited in the Herbarium Bogoriense (BO), Herbarium Biotrop (BIOT), Gottingen Herbarium (GOET) and Bangi Herbarium (UKMB) were examined, those are old and several recent specimens collected in West Java. Recent collections were made from Telaga Warna, Ciater, Gunung Halimun Salak National Park, Cibodas Botanical Garden, Bodogol Education Center and Conservation (Gunung Gede Pangrango National Park), University of Indonesia Campus Depok, including several collections from Banten Province. Twenty four species of Lejeuneaceae subfamily Ptychanthoideae are known from West Java, belonging to 8 genera namely Acrolejeunea (Spruce) Schiffn. (2 species), Archilejeunea (Spruce) Schiffn. (1 species), Lopholejeunea (Spruce) Schiffn. (10 species), Mastigolejeunea (Spruce) Schiffn. (3 species), Ptychanthus Nees (1 species), Schiffneriolejeunea Verd. (1 species), Spruceanthus Verd. (2 species) and Thysananthus Lindenb. (4 species). Two new records of Ptychanthoideae: Mastigolejeunea indica Steph. and Thysananthus minor Verdoorn are reported for Java. A determination key to the species is presented including their descriptions and illustrations.
