Judul: Kinerja Pengolahan Stroberi dengan Pendekatan Nilai Tambah dan Profitabilitas. (Studi Kasus: Kharisma Stroberi Kabupaten Bandung).
Abstrak: Stroberi adalah salah satu komoditas buah subtropis yang sangat potensial untuk dikembangkan di Indonesia. Stroberi mengandung kadar air tinggi sehingga mudah rusak. Salah satu upaya untuk mengatasinya yaitu dengan mengolah stroberi menjadi produk olahan seperti dodol, selai, dan manisan stroberi. Kharisma Stroberi merupakan salah satu usaha pengolahan stroberi yang terletak di Desa Alamendah, Kecamatan Rancabali, Kabupaten Bandung, Jawa Barat. Tujuan penelitian ini adalah untuk menganalisis kinerja pengolahan Kharisma Stroberi dengan menghitung besarnya nilai tambah dan profitabilitas. Analisis nilai tambah menggunakan metode Hayami dan tingkat profitabilitas dengan perkalian antara persentase Marginal Income Ratio (MIR) dan Margin of Safety (MOS). Hasil penelitian menunjukkan bahwa nilai tambah dari pengolahan dodol, selai, dan manisan stroberi sebesar Rp49 286, Rp11 658, dan Rp32 218. Profitabilitas yang dihasilkan dodol, selai, dan manisan stroberi sebesar 52.97%, 15.40%, dan 36.76%. Kinerja pengolahan dodol stroberi menghasilkan nilai tambah dan profitabilitas paling tinggi dibandingkan selai dan manisan stroberi.

Judul: Sistem Pemasaran dan Nilai Tambah Produk Olahan Stroberi di Desa Alamendah, Kecamatan Rancabali, Kabupaten Bandung.
Abstrak: Stroberi merupakan salah satu tanaman hortikultura yang memiliki nilai ekonomis yang tinggi dan memiliki peluang pasar cukup baik. Harga di petani lebih rendah dibandingkan di konsumen akhir menyebabkan marjin pemasaran tinggi. Selain itu, terdapat kegiatan pengolahan stroberi. Tujuan penelitian ini adalah menganalisis lembaga dan fungsi pemasaran, saluran pemasaran, struktur pasar, perilaku pasar, menganalisis marjin pemasaran, farmer’s share, dan rasio keuntungan terhadap biaya; menganalisis nilai tambah dodol, sirup, dan selai dengan metode Hayami. Pengambilan data menggunakan metode random sampling untuk responden petani, snowball sampling untuk responden lembaga pemasaran dan untuk responden pengolah stroberi. Hasil penelitian sistem pemasaran menunjukkan bahwa saluran satu, sepuluh, dan dua belas relatif efisien dalam menyalurkan stroberi grade AB dan C sedangkan saluran dua relatif efisien dalam menyalurkan stroberi grade BS. Hasil penelitian nilai tambah olahan stroberi menunjukkan bahwa dodol stroberi memiliki rasio nilai tambah dan tingkat keuntungan terbesar dibanding sirup dan selai.

Judul: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.
