Judul: Keragaman Plasma Nutfah Blewah (Cucumis melo L.) dari Enam Daerah di Jawa Timur
Abstrak: Genetic variability information anlong germplasm collections is very important for plant breeding, since effective utilization of germplasm is key factor of varieties development. A wide range variability of germplasm is needed by breeders, wich comprise not only standard cultivars and breeding lines related to them but also unexploited germplasm, as well as primitive cultivars or land races.

Judul: Keragaan Plasma Nutfah Blewah (Cucumis Me/O L.) Oari Enam Oaerah 01 Jawa Timur
Abstrak: Pengetahuan tentang keragaman genetik diantara koleksi plasma nutfah sangat dibutuhkan dalam pemuliaan tanaman, terutama bagi pemanfaatan plasma nutfah yang efektif. Keragaman yang luas dari plasma nutfah dibutuhkan oleh pemulia, mencakup tidak hanya kultivar standar dan galur-galur yang digunakan dalam pemuliaan, tetapi juga plasma nutfah yang tak tereksploitasi dan varietas lokal atau land races. Untuk mengetahui keragaman genetik plasma nutfah blewah, pengujian dilakukan terhadap 17 aksesi blewah yang dikumpulkan dari enam daerah di Jawa Timur. Penelitian dilakukan di Tajur. Bogor, pada ketinggian 250 m di atas pennukaan laut, dengan menggunakan Rancangan Acak Kelompok (RAK) tiga ulangan. Hasil penelitian menunjukkan adanya keragaman genetik pada peubah kuantitatif umur panen, tinggi tanaman, nomor buku tempat buah muncul/terbentuk, panjang mas, bobot buah, kelunakan kulit buah, lingkar buah, jumlah juring, panjang buah, tebal daging, dan kadar gula. Keragaman genetik antar aksesi bervariasi dari 36.2% untuk peubah bobot buah sampai 7.9% untuk umurpanen. Sumber genetik yang potensiai untuk pembentukan populasi dasar adalah aksesi nomor: 18 dan 6 untuk peubah bobot buah dan panjang buah, nomor: 21 dan 20 untuk peubah kelunakan kulit buah, nomor: 22 dan 28 untuk brix, serta nomor: 17 dan 6 untuk peubah tinggi tanaman. Koleksi tersebut rnerupakan sumber genetik potensial bagi perakitan varietas unggul Cucumis melD L.

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.
