Judul: Keanekaragaman Selaginella di Jawa Tengah
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).

Judul: Biodiversity, Ethnobotany, and Antioxidant Ability of Selaginella spp. from Halimun-Salak Mountain National Park (TNGHS).
Abstrak: Biodiversity and ethnobotany of Selaginella were studied in Halimun-Salak Mountain National Park (TNGHS) to describe the diversity and the use of Selaginella as medicinal plant. The diversity study of Selaginella was done by exploring Selaginella at 6 sampling points. The ethnobotany study of Selaginella was done by interviewing respondents at the villagers around Bunder Mountain, Citalahab Sentral, and Kasepuhan Adat Banten Kidul. There were eight species Selaginella found in TNGHS which were S. willdenovii, S. ornata, S. plana, S. intermedia, S. involvens, S. alutacia, S. subalpina and one species that has not been identified yet. The first two species were found dominantly in this location. The community in the location of study called Selaginella as paku rane. At the villages around Bunder mountain and Citalahab Sentral, Selaginella is also called as rande. The plant was traditionally used as fresh vegetables, postnatal and wound treatment, and body fitness maintenance. Antioxidant ability of Selaginella was tested by performing hydroxyl radical scavenging activity based on Fenton reaction. Three species of Selaginella were tested their hydroxyl radical scavenging activity. S. plana was the most potential species as an antioxidant followed by S. ornata and S. willdenovii. The crude extract of S. plana showed the best antioxidant activity at concentration of 75 μg/ml.

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.
