Judul: Evaluasi sifat fisik dan palatabilitas bakso ayam dengan substitusi STPP oleh khitosan
Abstrak: Daging ayam merupakan bahan pangan dengan nilai nutrisi tinggi yang biasa dikonsumsi sebagai masakan siap saji dan juga dapat diolah menjadi produk lebih lanjut seperti sosis, nuget dan bakso ayam. Sodium TriPolifosfat (STPP) merupakan bahan kimia yang ditambahkan pada pengolahan produk bakso untuk meningkatkan daya mengikat air sehingga produk menjadi lebih kompak dan kenyal. Khitosan merupakan bahan organik hasil pengolahan limbah cangkang udang. Bahan orgauik ini mempunyai fungsi yang sama dengan STPP. Tujuan dari penelitian adalah untuk mempelajari sifat fisik dan palatabilitas bakso ayam yang menggunakan bahan pengenyal khitosan. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap dengan tiga taraf substitusi STPP oleh khitosan (0%, 50%, dan 100%) dan empat ulangan. Parameter sifat fisik yang diamati yaitu pH (adonan dan bakso), stabilitas emulsi adonan, daya mengikat air bakso, rendemen, elastisitas dan kekerasan. Hasil penelitian menunjukan bahwa substitusi STPP oleh khitosan tidak mempengaruhi sifat fisik dan palatabilitas bakso ayam. Penambahan 0,3% STPP dalam pengolahan bakso ayam dapat digantikan oleh khitosan tanpa perubahan sifat fisik dan palatabilitas bakso ayam.

Judul: Penggunaan khitosan sebagai pengganti sodium tripolyphospate (STPP) terhadap sifat fisik dan organoleptik baso daging ayam
Abstrak: Chicken meat has an important role in nutritiion requirement fulfillment for human being. Meatball is homogenous mixture of meat, starch and seasoning that have been processed with extrusion and cooking. Chitosan is natural product that made from shrimp waste through demineralization and deproteinization. Generally, functiona of chitosan are similar with STPP, especially in water fixade, thus chitosan probably be able to replace STPP. This research was carried out to investigate physical and organoleptic properties of chicken meatball added by chitosan and STPP.

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.
