Abstract

Proteolytic bacteria are able to hydrolyze proteins into amino acid and smaller peptides. The objective of this study to determine the abilty of three Bacillus sp. isolated from leaf (BD), root (BA), and stem (BP) of palm oil to produce protease. The proteolytic activity was determine based on the amount of tyrosin liberated in Unit/mL, while the specific activity was indicated by activity per unit weight of proteins. Protein concentration of enzymes extracts was determined by Lowry method. The results showed that all isolates were able to produce protease. Protease activity of Bacillus sp. BD, BA and BP was (711,260 ± 0,735) x 10-3 U/mL, (708,536 ± 0,918) x 10-3 U/mL and (710,027 ± 0,091) x 10-3 U/mL in optimal production times of 24 hours, repectively.

Abstract

Penelitian bertujuan untuk mempelajari interaksi pemberian Trichokompos TKKS terformulasi dan pupuk nitrogen, pengaruh utama keduanya terhadap pertumbuhan dan produksi bawang merah (Allium ascalonicum. L) pada lahan gambut serta serapan hara N. Penelitian dilakukan secara ekperimen dalam bentuk faktorial 4 x 3 disusun menggunakan Rancangan Acak Lengkap (RAL). Faktor pertama yaitu Trichokompos TKKS terformulasi yang terdiri dari 4 taraf (15, 20, 25, dan 30 ton/ha) dan faktor ke dua yaitu pupuk nitrogen yang terdiri dari 3 taraf (150, 250, dan 350 kg/ha). Parameter yang diamati adalah tinggi tanaman, jumlah anakan dan bobot segar umbi per rumpun sampel. Hasil penelitian menunjukkan bahwa interaksi Trichokompos TKKS terformulasi 30 ton/ha dan pupuk nitrogen 350 kg N/ha meningkatkan bobot segar umbi per rumpun sampel secara nyata. Peningkatan dosis Trichokompos TKKS terformulasi dari 15 ke 30 ton/ha meningkatkan tinggi tanaman, jumlah anakan dan bobot segar umbi per rumpun sampel. Peningkatan dosis pupuk nitrogen dari 150 ke 350 kg N/ha meningkatkan tinggi tanaman dan bobot segar umbi per rumpun sampel.

Abstract

This study aimed to get to know the effect of different doses formulated Trichokompos doses on the growth and production of onion varieties in peat area, as well as to get a dose of Trichokompos formulated and the best interaction on several onion varieties. Research using split plot design draft with 12 combination and each treatment was repeated 3 times, analyzed in the laboratory and analysis of variance. The main plot treatments consisted of: (V1): Varieties Bauji, (V2): Varieties Maja Cipanas, (V3): Varieties Bima Brebes. Treatment subplot, consists of 4 levels, namely: T1: (5 ton / ha), T2 (10 tons / ha), T3 (15 ton / ha) and T4 (20 ton / ha). The data obtained were statistically analyzed using analysis of variance (ANOVA) followed by HSD test at 5% level. The results of the research showed that, the provision of oil palm empty bunches Trichokompos formulated doses of 10 ton / ha and a dose of 20 ton / ha on the varieties Bauji can increase the content of chlorophyll by 78.64% and K nutrient uptake value of 2.46 mg / plant. Provision of Oil Palm Empty Fruit Bunch Trichokompos formulated doses of 10 ton / ha on Maja Cipanas varieties could increase plant height of 24.93 cm and a dose of 5 tonnes / ha can increase the diameter of the bulbs by 24.70% and the provision of oil palm empty bunches Trichokompos formulated doses of 5, 10 , 15 and 20 ton / ha on Bima Brebes varieties can increase the number of tillers, the number of bulbs, tubers fresh weight, fresh weight of the plants, the rate of photosynthesis, transpiration rate, stomata conductivity, CO2 concentration, the value of N uptake and nutrient uptake value P. Increasing doses of oil palm empty bunches Trichokompos formulated from 5 to 20 ton / ha on the varieties Bauji, Maja Cipanas and Bima Brebes not affect all parameters observed.
