Pemanfaatan Pupuk Hayati Mikoriza untuk Meningkatkan Toleransi Kekeringan pada Tanaman Nilam

Tanaman nilam (Pogostemon cablin Benth) merupakan tanamanatsiri utama di Indonesia. Saat ini sekitar 90% minyak nilam duniadihasilkan oleh Indonesia. Produktivitas dan mutu nilam sangatdipengaruhi oleh faktor genetik dan lingkungan. Salah satu faktorlingkungan abiotik yang sangat berpengaruh terhadap pertumbuhan danproduksi nilam adalah cekaman kekeringan. Sampai saat ini informasimengenai toleransi nilam terhadap kekeringan masih sangat terbatas.Untuk itu, sebuah penelitian pemanfaatan pupuk hayati mikoriza untukmeningkatkan toleransi kekeringan pada tanaman nilam dilakukan padakondisi rumah kaca di Balai Penelitian Bioteknologi dan SumberdayaGenetika Pertanian pada bulan Januari sampai dengan bulan Juni 2003.Percobaan menggunakan rancangan acak lengkap (RAL) yang disusunsecara faktorial dengan 3 ulangan. Faktor pertama 2 taraf aplikasi mikorisamasing-masing dengan dan tanpa mikoriza. Faktor kedua adalah 4 tarafcekaman kekeringan dengan tingkat pemberian air (KL) yang berbedamasing-masing (1) tanpa cekaman kekeringan (100% KL), (2) cekamankekeringan rendah (75% KL), (3) cekaman kekeringan sedang (50% KL),dan (4) cekaman kekeringan tinggi (25% KL). Aplikasi mikoriza dilakukan1 bulan setelah tanam (BST), sedangkan perlakuan cekaman kekeringandiberikan 2 BST. Hasil penelitian menunjukkan bahwa nilam yang diberimikoriza mempunyai pertumbuhan yang lebih baik. Kekeringan menekanpartumbuhan dan hasil tanaman nilam secara linier. Sebaliknya, cekamankekeringan mampu meningkatkan kadar minyak dan patchouli alkoholdaun nilam. Interaksi antara kedua faktor yang diuji terjadi pada parameterpanjang akar total dan kadar prolina daun nilam. Keberadaan mikoriza didalam akar mampu meningkatkan toleransi terhadap cekaman kekeringan.Kandungan patchouli alkohol daun tertinggi dijumpai pada kombinasiperlakuan aplikasi mikoriza dengan cekaman kekeringan tinggi (25% KL)

Analisis Variabel-variabel Fundamental yang Berpengaruh terhadap Price Earning Ratio sebagai Dasar Penilaian Saham (Studi pada Saham-saham Indeks Lq 45 di Bursa Efek Jakarta)

Purposive random sampling and multiple regression using 16 emittent of LQ 45 stock indices samples were used]. The aims of this research is to know the influence of the fundamental variables on the price earning ratio, and the naturalness of LQ 45 stock indices value. The samples used are the big, established and stable companies included in calculation of LQ 45 indices, and thus would not apply to non LQ 45 indices at the JSX from 1999 through 2000. The results of the study indicate that (1) out of the four explanatory variables used: dividend payout ratio, return on equity, earning growth and financial leverage whereas simultaneously, all the variables showed significant influence; (2) dividend payout ratio was the most significant explanatory variable influencing the price earning ratio; (3) based on the price earning ratio analysis, no natural value was evidence of LQ 45 stock indices at the JSX

Analisis Komponen Reverse Mean pada Harga Saham melalui Perspektif Ekonomi Makro di Bursa Efek Jakarta

Reverse mean reversion and predictability of stock return is probably the most well researched topic in the empirical research of financial economics. Numerous empirical studies have been unable to reject the hypothesis that return unpredictable and that stock price follows a random walk or martingale process. The essence of the mean-reversion hypothesis is that the stocks price contains a temporary component. Thus, the market value of stock deviates from the fundamental value but will revert to its mean. The objective of this study is to test the mean reversion hypothesis in Indonesian capital market, by investigate the size and significance of mean reversion component of stock prices at the Jakarta Stock Exchange, for the period of January 1990 through December 2003, and to investigate the size of the forecast error variance decomposition for real stock prices which is caused by permanent innovation and temporary innovation for a horizon of 2, 3, 4, 6, 12 and 24 months. By placing appropriate structural restrictions on a vector auto-regressive system estimated for the period of January 1990 through December 2003, it was found that the temporary component in the stock prices at the Jakarta Stock Exchange has significant size. From this, it can be inferred that the pattern of share price movements at the Jakarta Stock Exchange has a temporary component which will gradually disperse or undergo reverse mean. This evidence supports the mean reversion hypothesis that stock price are not pure random walks and predictability of stock return and reject the random walk hypothesis
