Judul: The impact of economic policy and trade liberalization on the performance of the Indonesia soybean industry
Abstrak: Kesenjangan antara produksi dan konsumsi kedelai nasional disebabkan karena lambatnya pertumbuhan produksi dibandingkan laju partumbuhan konsumsi, terutama karena pesatnya perkemkembangan industri pengolah kedelai. Adapun kendala yang dihadapi dalam pengembangan produksi kedelai Indonesia adalah: (1 ) tingkat penerapan tehologi yang rendah (2) tigginya harga input dan rendahnya kedelai, serta (3) rendahnya kemitraan dan partisipasi perusahaan swasta dalam pengembangan kedelai., The gap between national production and consumption of soybean is caused by the slow production rate compared to the high consumption rate as result of the high growth rate soybean processing industry. Constraintts facing the development of soybean production in Indonesia are (1) inadequate application technology, (2) high price of input and low price of soybean, and (3) lack of partnership and participation of private business in developing soybean.

Judul: Impact of soybean development policy on performance and soybean consumer and producer welfare in Indonesia
Abstrak: Soybean is one of the major food commodities. It is a food crop that is rich in protein and it has an important role as a plant nutrients protein source that can improve people’s nutrition. Soybean demand that keeps increasing cannot be complied with domestic production, instead of the fact that Indonesia used to be a self-relying soybean country in 1992. However, the production then decreased gradually until 2010, so finally it must be imported greatly. The big amount of imported soybean is enhanced by the change of soybean business, namely the existence of free trade so that there is a lot of imported soybean with reasonable prices. Imported soybean has made farmers reluctant to grow soybean seeds. This is because local soybean is not competitive enough to imported soybean, seen from the viewpoint of price as well as quality. Farmers feel they do not have any incentive for growing soybean, so that their welfare becomes lower, especially when there is no guarantee during the great harvest. The general objective of this research is analyzing impact of soybean development policy on supply, demand changes and soybean consumer and producer welfare in Indonesia. Methods: The survey was conducted on time-series datas between 1981 to 2010. Data were analyzed using a simultaneous equation model and parameter was estimated using the two stage least squares (2SLS) method that applies SAS/ETS (Statistical Analysis System/Econometric Time Series) program Versi 9.1 for Windows. Conclusions: Soybean production in Indonesia is strongly influenced by the price of soybeans at the farm level, prices of production facilities especially urea fertilizers and soybean seeds, labor wage and soybean imports in which these factors are influential through changes in the increase of crop acreage and soybean productivity. Soybean crop area width is very responsive to changes in prices or wages of agricultural labor both in short term and long term while soybean productivity is less responsive to its constituent factors. One of simulation policies was to increase soybean price in producer level at 35 percent, it would stimulate farmers to increase harvested area, soybean production and farmers welfare. Implications of Policies to increase soybean production, the government should formulate policies that will provide benefits to both producers and consumers. Policies that are partially formulated will not benefit both parties, but only one party. To encourage farmers to increase their production, government policies must not only provide a subsidy of production facilities but also give guarantees in price during harvest time because at this time the bargaining power of farmers is very low. Price protection policy is aiming at output price stability that will determine the farmers’ income, which in turn will change their welfare.

Abstrak: I reevaluated taxonomic of subgenus Papurana position from Halmahera based on morphological and molecular analyses. My results show that two separate species occur on the Halmahera Island, each nested within two distinct clades (hereafter papua clade and celebensis clade), one of which corresponds to H. moluccana (celebensis clade) and the other to an unidentified species (papua clade). By p-distance ranging from 6.9 to 11.5% on the 16S rRNA gene, the unidentified species (Hylarana sp.) is genetically different from all congeners of the papua clade. The Hylarana sp. can be distinguished from all congeners by following combination of charactes: vomer teeth in two oblique rows with narrow inter-vomer distance; snout rounded dorsally; dorsum with few scattered cone-shaped tubercles that are black with white tips; distinct skin folds (ridges) on the dorsal side of the thigh coinciding with dark brown cross bars; a marbled pattern on the ventral side of the thigh and yellowish groin. I also present new data for H. daemeli, H. volkerjane, and H. arfaki from the western region of Papua. Furthermore, I found that H. celebensis has numerous mtDNA lineages, indicating cryptic diversity within the celebensis clade. The discovery of two separate species on Halmahera necessitates more research into the biogeographic history of Hylarana in Northern Moluccas.
