Abstrak: Selaginella is a single genus belong to family Selaginelaceae which include approximately 750 species spread all over the world. The diversity of Selaginella can be found in lowland to mountain rainforest. This study aimed to describe the diversity of morphological characters and the distribution of Selaginella in Central Java, then to provide descriptions and identification key of Selaginella species in Central Java. The method used to assess the diversity Selaginella in Central Java included observation and identification of morphological characters. In Central Java, there were found 10 species of Selaginella, namely S. plana, S. remotifolia, S. involvens, S. ornata, S. ciliaris, S. opaca, S. modica, S. aristata, S. subalpina, and Selaginella sp. Selaginella varied on some morphological characteristics such as branching pattern, rhizofor, lateral leaves, median leaves, axillary leaves, and Strobilus shape. The distribution of Selaginella is fairly even in Central Java ranging from the altitude of 200 to 2771 m asl. Selaginella species found in the lowest altitude was Selaginella sp. (200 m asl), while at the highest altitude was S. plana (2771 m asl).

Abstrak: Selaginella is a genus of ferns in the family Selaginellaceae. It is characterized by having small leaves and the spongarium on the tip of each branch. The society of West Java have been a long time used Selaginella as vegetable and dill, but the taxonomic information of Selaginella in West Java is still poorly known. The aim of this research was to describe the diversity of Selaginella in West Java. This research used 316 herbarium specimens of Selaginella collected by Plant Taxonomy Laboratory, Department Biology of Bogor Agricultural University and Herbarium Bogoriense Botanical, Research and Development Cibinong. From each specimen was observed the mophological characters, recorded the spread site, identified, then arranged the identification key. This study showed that 18 species found in West Java, namely S. aristata, S. biformis, S. ciliaris, S. frondosa, S. intermedia, S. involvens, S. mayeri, S. opaca, S. ornata, S. plana, S. remotifolia, S. rothertii, S. subalpina, S. subspinulosa, S. uncinata, S. willdenovii, S. zollingerian and Selaginella sp 1. Selaginella is able to live at altitudes ranging from 20 m above sea level (asl) to > 2500 m asl, with a variety of habitats including primary forest, in the rice fields, near the waterways, and in the open area. An identification key of Selaginella in West Java was provided in this paper.

Judul: Sectoral Effects Of Monetary Policy
Abstrak: The purposes of this study are three folds: (1) identifying which channels are effective for transmission of monetary policy; (2) assessing whether the transmission mechanisms at industry level are consistent with that at aggregate level; and (3) explaining why and how a channel becomes effective. The analyses are facilitated impulse response function (IRF) derived from a vector autoregression (VAR) model. Three channels are identified in this study: interest rate, real credits and exchange rate channels. The IRF results show that exchange rate is the only effective channel in affecting aggregate output and at least in five industries (the manufacturing industry; the construction industry; the trade, hotel, and restaurants industry; the transport and communication industry; and the finance, real estate, and business services industry). Meanwhile, the other two channels are not effective at aggregate and all industry. This finding suggests that there is some form of consistency between aggregate effects and industry effects. Moreover, the effect of real depreciation tend to be contractionary and thus supporting the idea of Krugman and Taylor (1976) among others. Output contraction seems to be associated with inflationary effect of the depreciation. This is a truly Keynesian type demand side story: following a real currency depreciation, purchasing power tends to weaken which then soaks the aggregate demand.
