This research studies the process of extracting citronella oil by the steam-hydro distillation method with microwaves (microwave). In addition, study the effect of temperature (105 ͦ C, 110 ͦ C, 115 ͦ C) and the size of the material enumeration (0.5 cm; 1 cm; 1.5 cm) on the yield of oil produced. This research was conducted by the steam-hydro distillation method. In this method a solvent is added in the form of water to dissolve the oil in the fragrant lemongrass stems and leaves. The resulting steam is condensed and then distillate in the form of a mixture of oil and water is taken after 120 minutes and separated using a separating  funnel. From the results of the study, it was found that the% yield of high citronella oil in the variable size of the enumeration material was 0.5 cm at a temperature of 115 with a yield of 1.92%. The content of Citronella obtained in the oil of this research is 59.28%. The density of lemongrass oil is 0.875. The refractive index value is obtained in the range of 1.46735- 1.46925.Keywords :  Essential Oil, Fragrant, Steam-hydro Distilation, Microwave

Residual result from cyrup of calamansi was plenteous and did not used yet well. This research was used to utilize that residual industry of cyrup calamansi by cultivating it became essential oil by using distillation method. The residual result from cyrup of calamansi were devided into three types; residual result in solid, residual result in liquid 1, and residual result in liquid 2. From 100 kg fresh calamansi could produce 40 kg residual result in solid, 20 liters liquid 1 and 10 liters liquid 2. Each of them produced essential oil which 300,79 gr (from residual solid), 354,39 gr (from residual result of liquid 1) and 22,33 gr (from residual result of liquid 2). By looking at the yield, residual result industry of cyrup calamansi which contain the highest of essential oil was residual result from liquid 1 with the yield 1,771%, essential oil from the solid was 0,752% and the yield from the residual liquid was 0,223%. The essential oil from cyrup of calamansi was near to the characteristic of lime essential oil in density, refractive index and the yield but for solubility in alcohol was different.

Lemongrass essential oil is obtained from the distillation of lemongrass plant. The main content of this oil is sitral content. This study aimed to determine the quality of essential oil produced by the method of water-steam destillation. The experiment was done by water-steam destillation of stalks and leaves of lemongrass, respectively, under 3 repeatations. Lemongrass essential oil obtained from leaves was 0,399%, which is 10-fold greater than the yield of the stalks (0,039%). The specific gravity of Lemongrass essential oil obtained from leaves was 0,8987 where as the specific gravity of Lemongrass essential oil obtained from stalks was 0.8940. The refractive index of lemongrass oil obtained from  leaves was 1.4876 while the refractive index of lemongrass oil obtained from stalks was 1.4880. Based on solubility in 70% alcohol test, lemongrass essential oil obtained from the leaves and stalks were a little bit cloud at a ratio of 1: 5. Based on its yield, it can be concluded that the leave plant produced more oil. However, the quality of both oils showed that lemongrass essential oil met the EAO Standard.

Medicinal Value

Mosquito-borne diseases such as malaria, filariasis, chikunguniya, yellow fever, dengue and Japanese encephalitis are the major cause of remarkable morbidity and mortality in livestock and humans worldwide. Since ancient times, aromatic plants are used for their medicinal value. Essential oils derived from these plants may be used as effective alternatives/adjuvants in pharmaceuticals, biomedical, cosmetic, food, veterinary and agriculture applications. These oils have also gained popularity and interest for prevention and treatment of various disorders. However, several reports on adverse effects including skin eruption, contact artricaria or toxic encephalopathy in children are available for synthetic repellent in the literature. Thus, natural insect repellents like essential oils have been explored recently as an alternative. One such essential oil studied widely, is citronella oil, extracted mainly from Cymbopogon nardus. This essential oil has exhibited good efficacy against mosquitoes. It is a mixture of components including citronellal, citronellol, geraniol as major constituents contributing to various activities (antimicrobial, anthelmintic, antioxidant, anticonvulsant antitrypanosomal and wound healing), besides mosquito repellent action. Citronella essential oil is registered in US EPA (Environmental protection agency) as insect repellent due to its high efficacy, low toxicity and customer satisfaction. However, poor stability in the presence of air and high temperature limits its practical applications. Since specific knowledge on properties and chemical composition of oil is fundamental for its effective application, the present review compiles and discusses biological properties of citronella oil. It also sheds light on various formulations and applications of this essential oil.

Brown Eye Spot

The rust and brown eye spot are the main coffee diseases. The losses are due to intense defoliation of plants, which has reduced its production and longevity. The brown eye spot also occurs in fruits, with negative effects on the beverage quality. Some essential oils have presented promising results in the control of plant diseases, as an alternative to the use of fungicides. The objective of this study was to evaluate citronella essential oil in the control of rust and brown eye spot and in the activation of coffee plants defense responses. Twelve-month-old plants were sprayed with citronella oil 1000 µL L-1, acibenzolar-S-methyl 200 mg L-1 and tebuconazole fungicide 200 mg L-1. Plants were inoculated with Hemileia vastatrix and Cercospora coffeicola seven days later. The application was repeated after 30 days. Plants with five months were sprayed with the same treatments to assess the induced defense responses. Citronella oil controlled rust and brown eye spot with efficiencies of 47.2% and 29.7%, respectively, while tebuconazole presented control of 96.5% and 90.5%, respectively. Acibenzolar-S-methyl reduced brown eye spot by 55.9% and showed no significant control of rust. Citronella oil increased peroxidase and chitinase activities in five months coffee plants 336, and 24 and 336 hours after spraying, respectively. Acibenzolar-S-methyl increased peroxidase, chitinase and ββ-1,3-glucanase activities 192, 288 and 336; 24 and; 240 hours after spraying, respectively. The treatments did not increase accumulation of phenols, but a significant increase in lignin was observed in plants sprayed with citronella oil.

This study aimed to investigate the use of water hyacinth to produce liquid smoke. The study observes the temperature and time variables of yield, pH, density, and refractive index in the production of liquid smoke from water hyacinth. The sequence of the work is as follows: first, water hyacinth was cut into 5 cm sections and then sun-dried for 2–3 d, depending on the weather. Next, 550 g of dried water hyacinth was added to the pyrolysis reactor. The temperature variations were 200°C, 400°C, and 600°C, and the time variations were 1, 4, and 7 h. As a result, liquid smoke was produced with varying yield, pH, densities, and refractive indices. The best results in this research are liquid smoke pyrolysis at a temperature of 400°C and 4 h with the acquisition of a yield of 93 mL, pH 2–4, a density of 1.080,8 gr/mL, and a refractive index of 1.339,6, with chemical component 41.45% total acid, 2.44% phenol and 56.10% carbonyl.
