Judul: Penentuan Best Opening First (BOF) dengan Pertimbangan Angka Bentuk Dolok Pada Pola Penggergajian Satu Sisi
Abstrak: Industri penggergajian merupakan perusahaan yang padat bahan baku artinya tidak kurang dari setengah total biaya produksi merupakan biaya pengadaan kayu bulat. Kondisi ini menyebabkan perlunya efisiensi penggergajian yaitu dengan cara mengkonversi kayu bulat (dolok) menjadi kayu gergajian sebanyak mungkin (memaksimumkan rendemen).

Judul: Ketersediaan Tenaga Operator dan Peluang Penggunaan Feeder Mekanis pada Penggergajian Kayu Mesin Di Kabupaten Bogor.
Abstrak: Ketersediaan tenaga operator terampil secara kuantitatif akan menentukan produktivitas fisik/volume, dan secara kualitatif akan menentukan kesesuaian dengan kualitas output yang diinginkan.Masalah ketersediaan tenaga operator terampil diharapkan dapat diatasi dengan bantuan alat feeder mekanis.Dari penelitian ini industri penggergajian kayu di Kabupaten Bogor secara umum belum pernah mengetahui dan menggunakan alat tersebut. Pengelolaan industri umumnya masih sederhana, di mana dari sebanyak 30 sampel, hanya 2 unit (6.7 %) industri penggergajian kayu memiliki sistem pembagian kerja, dan hanya 3 (10%) unit yang memakai sistem K3. Kapasitas volume penggergajian kayu beragam dan berkisar antara 20 m3hingga 192 m3. Sebanyak 73.3 % industri penggergajian kayu termasuk kapasitas produksi kecil dan sedang, sertaumur berkisar antara 5 bulan sampai 29 tahun dengan rata-rata 8.7 tahun. Jenis kayu yang diolah dan kualitas kayu yang dihasilkan juga bervariasi, ada kayu berkualitas tinggi, sedang, dan rendah, yang akan digunakan sebagai bahan bangunan, pallet, dan meubeler. Penjualan hasil kayu gergajian masih disekitar Jabodetabek, sehingga kesadaran pentingnya kualitas masih rendah (93.3%).Mereka (53.3 %) juga menilai adanya kesulitan menyediakan tenaga terampil, dan mereka (53.3 %) menganggap alat feeder mekanis DD-1 merupakan solusi untuk mendapatkan hasil gergajian yang lurus dan berkualitas baik. Walaupun sebanyak 25 unit (83.3%) industri penggergajian kayu menganggap kualitas berpengaruh terhadap harga, tapi kenyataannya kualitas tidak berpengaruh terhadap harga karena adanya sistem pemasaran oleh paguyuban.Penggunaan alat feeder mekanis diminati dan diharapkan dapat meminimalisasi angka kecelakaan kerja.Sebanyak 21 unit (70 %) yang memperkirakan harga alat feeder mekanis yang terjangkauuntuk investasi berkisar pada harga Rp 2.000.000- Rp 6.000.000.

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.
