Effectiveness of Indonesian Essential Oil Mixture of Lemongrass, Cananga, and Patchouli in Relaxation Through Inhalation: a Clinical Test on Healthy Woman with High Potential for Stress

Relaxation is one of many mechanisms for coping with stress. One of the most widely used methods for relaxation is aromatherapy with the application of essential oils. Known for their therapeutic benefits, essential oils can be extracted from various Indonesian native herbs such as lemongrass (sereh wangi or Cymbopogon winterianus), cananga or ylang-ylang (kenanga or Canarium odoratum), and patchouli (nilam or Pogostemon cabin). This study aims to examine the effectiveness of a mixture of Indonesian essential oil made of lemongrass, cananga, and patchouli extracts. Experiment was conducted by asking a number of subjects to inhale the oil mixture and assessing its effectiveness in terms of psychological relaxation by using Visual Analog Scale or VAS) and of physical relaxation by examining the subjects’ blood pressure (MAP), pulse frequency, and breathing frequency. The result was then compared with that of lavender oil and with the control group. The study was conducted on 60 healthy women through single-blind clinical trials (before and after) using the “intent to treat” approach, followed by a startle test. Participants were divided into three groups: (1) 20 participants who were treated with Indonesian essential oil mixture, (2) 20 participants who were treated with lavender oil, and (3) 20 participants who served as the control group. Psychological relaxation measurement showed that Indonesian essential oil mixture produced the same degree of effectiveness as lavender oil and the control groups did, although both treatments tended to produce better results than the control group did. However, physical relaxation measurement showed that Indonesian essential oil mixture produced a higher degree of effectiveness than lavender oil and tended to produce a better result than the control group did, especially in terms of blood pressure based on MAP scores.    &nbsp

Sensitivity Analysis of Transportation Production Costs in Indonesia

The transportation production cost (TPC) considerably has strong influence to the national economic condition. This paper focused on the analysis of the transportation production cost sensitivity in relation to the variation of the external affecting factor, which are fuel price, rupiah exchange rate and Bank of Indonesia interest rate. Based on the R2 values, the TPC components in general have significant correlation, with the fuel prices. However, they do not have high correlation to the fluctuation of interest rate and rupiah exchange rate. The sensitivity analysis shows that a 10% rise on fuel price would cause 6%, 2%, 7%, 2.4%, and 4.9% rise on the TPC of intercity bus, ferry ship, interisland ship, train, and airline, respectively

Variasi Spasio-temporal Jenis Makanan Ikan Motan, Thynnichthys Polylepis Di Rawa Banjiran Sungai Kampar Kiri, Riau [Spatio-temporal Variation in the Diet of Thynnichtys Polylepis in Floodplain River of Kampar Kiri, Riau]

The research aimed to describe diet composition of Thynnichthyes polylepis. The diet compositions of population from two sites (Mentulik and Simalinyang) in floodplain river of Kampar Kiri, were compared according to the month. Fishes were captured using experimental gillnet and trap. For food habits analysis, the index of preponderance method was used. The collections were performed monthly from July to December 2008, where the stomach contents of 479 specimens were assessed. Prey items of T. polylepis were basically composed of phytoplankton and zooplankton, especially Cocconeis, Nitzschia, Navicula, Cyclotella, Pleurotaenium, and Testudinella. At site Mentulik, the most common items were Cocconeis, Nitzschia, and Navicula. Conversely, at site Simalinyang, Cocconeis, Pleurotaenium, and Nitzschia more representative. In general, main food of fish origin showed the highest index values at Mentulik, whereas at Simalinyang. The composition of items varied monthly, especially at Simalinyang. Food habits of fish may be flexible according to resource availability in spatial and temporal variation
