The objectives of this study are to obtain essential oil from Sedap Malam (Tuberose) flower via extraction method and to characterize the physical and chemical properties of the essential oil produced, such as density, rendement, and chemical composition. The extraction process was carried out by using methanol solvent. The ratio between Sedap Malam flower and the methanol solvent was 1:5. After the extraction process of the essential oil finished, the essential oil and the solvent were separated via a simple distillation process. The collected essential oil was then characterized using Gas Chromatography-Mass Spectrophotometry (GC-MS) apparatus and Fourier Transform Infra-Red (FT-IR) analysis to investigate the content of the essential oil extracted from Sedap Malam flower. The physical characterization results showed that the essential oil has average rendement value of 12.605 % and density value of 1.0905 g/mL. Additionally, organoleptic test was carried to test the response of respondents toward the color and odor/fragrance of the essential oil extracted from Sedap Malam flower. Most of the responses were included in categories of “Like” and “Really like”. Additionally, for the fragrance, most of response of the respondents for all the four samples of essential oil were in category of “Really like”.

Bat Guano

Some fertilizers practices could be used to improve Baraka seed Nigella sativa L. as a medicinal crop like organic farmyard manure which efficiently applied to enhance growth and yield. Thus, a field experiment was conducted out at Research Station in Tikrit-Iraq during 2012/2013 season to estimate the impact of bat guano (0, 75, 125 and 175 kg.ha-1), seaweed extract as kelpak (0, 1, 2 and 3ml.l-1) on some physical and chemical essential oil components. Two factors were arranged in factorial experiment in randomized complete block design with three replicates. Thus, results revealed that application of bat guano at 125 kg.ha-1 was superior in enhancement of essential oil and its some physical and chemical properties as essential oil% of 1.53%, specific gravity of 0.95 g.cm-3, refractive index of 1.82, essential oil density of 0.93, dithymohydroquinone of 37.44µg.µl-1 and thymol of 25.73 µg.µl-1. Moreover, kelpak (3ml.l-1) significantly improved physical and chemical properties of essential oil which were essential oil% of 1.52%, specific gravity of 0.93 g.cm-3, refractive index of 1.72, and essential oil density of 0.94 and thymol of 25.92 µg.µl-1. Whereas, the main component dithymohydroquinone effected by application of 2 ml.l-1kelpak of 37.04 µg.µl-1. It could be recommended to use bat guano as alternative to chemical fertilizer fortified with foliar application of seaweed extract as kelpak so as to improve physical and chemical properties of essential oil.

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

And Chemical Properties

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.
