Abstract

Screening to genomic library of soybean cultivar Slamet in ë phage to isolate the gene encoding for peroxidase(per) was performed by two steps. cDNA of per gene from Arabidopsis thaliana labeled by alkalin phosphatasewas used as probe. The first screening was done by using 105 recombinant pfu (plaque forming unit). The secondscreening was carried out on 100 recombinant pfu isolated from the first screening. The result of second screeningshowed that all screened clones were supposed containing per gene. The ë phage resulted from second screeningwas infected into E. coli BM 25.8. Due to the Cre recombinase in E. coli BM 25.8, two lox P sites flanking the insertDNA of soybean created recombination. The recombination in loxP sites resulted the excision and formedrecombinant plasmid containing per gene of soybean. To multiply, the recombinant plasmid was introduced into E.coli DH5á. Analysis southern hibridization of recombinant plasmid cut by Bam HI showed that Bam HI 3.7 kbfragmen of S52121R clone, 5,3 kb of S2412R clone, 2,4 and 5,3 kb fragments of S2532R clone were supposed tocontain per genes.

Abstract

AbstractIn the last two decades many countries have been starting to employ Inflation Targeting Framework (ITF) as their main monetary policy framework. This is done to achieve an objective of anchoring public expectation on inflation which in the end will steer the price level movement towards ITF’s ultimate target of relatively low and stable inflation rate. By conducting Difference-in-Difference method on panel data consisting of five countries implementing ITF since 2001 and twenty-one selected non-ITF countries for period 1990-2010, it is statistically proved that ITF adoption has a significant effect on inflation. In case of Indonesia, through Structural Break approach, the implementation of ITF since 2005 is also proved able to lower and stabilize inflation rate.Abstrak Dalam dua dekade terakhir ini banyak negara yang telah mulai menggunakan Inflation Targeting Framework (ITF) sebagai kerangka utama kebijakan moneter mereka. Hal ini dilakukan guna mencapai tujuan pengendalian ekspektasi publik yang pada akhirnya akan mengendalikan pergerakan tingkat harga relatif rendah and stabil. Dengan menggunakan metode Difference-in-Difference pada data panel, yang terdiri dari lima negara yang telah mengimplementasikan ITF sejak tahun 2001 dan dua puluh satu negara bukan pengguna ITF, untuk periode 1990-2010, disimpulkan bahwa ITF memiliki dampak signifikan pada tingkat inflasi. Untuk kasus Indonesia yang telah mengimplementasikan ITF sejak tahun 2005, melalui metode Structural Break disimpulkan hasil yang sama, yaitu tingkatan harga yang rendah dan stabil.

Abstract

This article investigates whether following Bank Indonesia's explicit inflation targets (forward-looking) is a more accurate method of predicting inflation rate in Indonesia than forecast methods utilizing past information of macroeconomic data (backward-looking). The analysis is conducted by performing naive, univariate, and multivariate time-series models with an out-of-sample forecast evaluation period of January 201-December 2016. It is found that the backward-looking approach outperforms the forward-looking approach at all forecast horizons, indicating that Bank Indonesia still does not succeed to anchor inflation expectation towards the desired level.
