Judul: Morfologi, Pola Protein Dan Kariotip Eulipoa Wallacei G. R. Gray, 1860 (Megapodiidae, Galliformes, Aves)
Abstrak: Tujuan penelitian ini adalah untuk mengetahui morfologi termasuk morfometri, pola warna bagian-bagian tubuh, pola protein dan kariotip burung Eulipoa wallacei sebagai informasi dasar untuk menelusuri ke- dudukan taksonomi dan kekerabatannya dengan spesies burung lain yang tergolong famili Megapodiidae. Penelitian ini dilakukan dalam dua tahap, yaitu (1) penelitian di lapang yang terdiri dari penentuan lokasi, penangkapan burung untuk pengukuran morfometri dan pengamatan pola warna, pengambilan sampel darah dan pengambilan telur, (2) analisis pola protein dan kariotip. Tahap penelitian di lapang dilaksanakan di desa Kailolo, kecamatan pulau Haruku, Maluku Tengah. Di daerah ini terdapat tempat bertelur burung Eulipoa wallacei yang dekat dengan pantai, dengan keadaan pasir berwarna putih. Di seki- tar lokasi ini terdapat hutan kecil dan hutan ini merupakan tempat berlin- dung sementara bagi burung-burung betina dewasa yang belum sempat meletakkan telur pada malam harinya karena hari terlanju bagi anak burung hutan ini merupakan tempat hidup sementara atau tempat pertumbuhan anak burung sampai dapat terbang jauh ke habitatnya yang sebenarnya. Temperatur lubang tempat meletakkan telur pada musim panas maupun hujan pada kedalaman 40 dan 80 cm berkisar antara 31-35 °C. Musim bertelur di lokasi ini terjadi sepanjang tahun dan puncaknya pada bulan Oktober s/d Maret khususnya selama bulan terang. Peletakan telur terjadi pada malam hari. Bentuk telur bulat panjang, berwarna kuning kecoklatan sampai coklat kemerah-merahan. Telur burung Eulipoa wallacei memiliki panjang rata-rata 78,18 mm, diameter 48,89 mm dan berat 102,82 gram….dst

Judul: Kajian Perkembangbiakan Embrio Burung Mamoa (Eulipoa wallacei) di Kecamatan Galela Kabupaten Halmahera Utara
Abstrak: Some studies on embryo’s reproduction on bird has already been done, however scientific studies on mamoa bird are very few. This research was done to study characteristics of hatching nest on laying habitat, embryo development stages which naturally and artificially hatched, compare the rate of natural and artificial hatchability and also vibiliability of Mamoa chick at 1 month old. This research was done in 3 laying area around the beach in Galela district. By using 70 eggs each or natural and aryificial hatching. Parameter observed were nesting and hatching characteristic. The result showed that laying habitat of Mamoa bird around the beach were sandy soil SiO2 pH between 5.9-6.7, and high SiO2 content (51.2%). Hatching nests dimension were affected by season (rain/dry) and moon’s shine (dark/light). Embryo’s weight were high on artificial hatching than natural hatching on day 21 to 35, while in other day were not insignificant. Both of naturally and artificially hatched eggs were develop on day 10. Fertility and hatchability on natural hatching wete better (100%) if it compared to artificial hatching (81.18%). One month age Mamoa bird on viability of natural and artificial hatching were (100%). Regression analysis between egg weight and hatching weight on both hatching methods shows linier correlation.

Judul: Perdagangan Karet Spesifikasi Teknis antara Thailand dan China
Abstrak: Thailand and China play important roles in the trade of natural rubber because both countries are respectively the biggest exporter and importer of natural rubber in the world. However, there are many problems such as supply shortage of natural rubber to meet the demand for natural rubber and unstable prices. Therefore, it is necessary to examine how the behaviors of both countries affect the supply, demand and price of natural rubber in international trade in particular technical specified rubber (TSR) where this type of rubber have the greatest amount traded between the two countries. This study has two main objectives that include the following: (1) to analyze the factors that influence the export supply, import demand and price for technical specified rubber in Thailand and China, and (2) to analyze the impact of internal factors and external factors alteration to the export supply, import demand and price for technical specified rubber in Thailand and China. This study used econometric analysis and implemented two stage least squares (2SLS) method and simultaneous equation model and used time series secondary data from 1990 to 2010. The results showed that: (1) Thailand’s supply for TSR exports to China was influenced by amount of TSR Thailand export to China in previous year and amount of TSR Thailand production, while Thailand’s supply for TSR exports to non-China was influenced by amount of TSR Thailand production and amount of TSR Thailand exports to China, (2) China’s demand for TSR imports of Thailand influenced by China’s participation in WTO, amount of automotive production in China and China’s real price import of TSR, while China’s demand for TSR imports of non-Thailand influenced by amount of China’s TSR imports from non-Thailand in previous year, amount of automotive production in China and import tariff in China, and (3) world TSR real prices was influenced by world TSR real price in previous year, amount of exports supply of the world in previous year and amount of imports demand of the world, while real price TSR exports of Thailand was influenced by world TSR real price, amount total of TSR Thailand exports and USA fuel real price, while real price TSR import of China was influenced by world TSR real price ratio and real price TSR import of China in previous year. Historical simulation and forecasting simulation results show that increased production quantities of TSR policy in Thailand and abolition of import tax of TSR policy in China performed within TSR rubber trade between Thailand and China because it enabled to increase foreign exchange for Thailand's technical specified rubber exports.
