Full textAbstract:
In Vietnam, there were several research on essential oil extraction from citronella leaves by direct steam distillation. However, most studies focused on the effects of temperature, pressure, and distillation time on essential oil yield, mainly aiming to reduce distillation time with little attention to the chemical composition of the citronella oil obtained. Meanwhile, citronella essential oil contains no fewer than 20 constituents with the 3 most important constituents being citronellal, geraniol, and citronellol. The Vietnamese National Standard 11426:2016 (equal to ISO 3848:2016) regulates the chemical content of Java citronella essential oil for export as citronellal 31-40%, geraniol 20-25%, and citronellol 8.5-14%. The current Java citronella oil often has a citronellol content below 20%, thus failing to meet the standard in ISO 3848:2016. The aims of this research were to optimise the distillation process parameters, including temperature, pressure, and distillation time for extraction of citronella essential oil from Tay Giang citronella by direct steam distillation method in order to maximise yield and maintain geraniol content above 20%. The research results have determined the following optimal technical parameters for the extraction of Tay Giang citronella essential oil: temparature 116±1oC, pressure 1.2±0.05 atm, and distillation time 126±1 min to obtain an essential oil yield of 0.94% with a geraniol content of 20.17%. These results can be used to identify the technology for industrial-scale production of Tay Giang citronella essential oil for export purposes.

Objective: Optimum condition for the extraction of citronella oil from citronella (Cymbopogon winterianus) using supercritical carbon dioxide (SC-CO2) was investigated.Methods: In order to determine the optimum extraction condition, a Taguchi experiment with L9 orthogonal array design was used. Effects of pressure, temperature and dynamic extraction time on citronella oil yield were investigated at levels ranging between 10-15 MPa, 35-45 °C and 60-180 min, respectively.Results: The highest citronella oil yield (3.206%) was achieved at a factor combination of 15 MPa, 50 °C and 180 min. The obtained citronella oil yield from SC-CO2 extraction was higher than that of percolation as the solvent extraction method using ethanol, which gave a citronella oil yield of 1.4%. The experimental oil yield at optimum condition was in accordance to the values predicted by a computational process using Taguchi method. Analysis of variance (ANOVA) with 95% confidence interval indicates that extraction temperature is the most significant factor in maximizing citronella oil yield, followed by dynamic extraction time and pressure.Conclusion: Optimization process for oil yield from SC-CO2extraction of citronella (Cymbopogon winterianus) was successfully performed using Taguchi L9 orthogonal array design. This study demonstrates that Taguchi method was able to simplify the experimental procedure of SC-CO2 process.

Full textAbstract:
Escalation fuel consumption occurs in various regions of the world. However, world oil reserves decline from year to year so that it becomes scarce and causes oil prices to surge up. This problem can be solved by saving fuel consumption. One method of saving fuel is adding bio-additives from citronella oil as a sustainable resource to diesel fuels. Citronellal, citronellol and geraniol are the main components of citronella oil which can be used as fuel additives. This study aimed to evaluate the effect of citronella oil fractions as bio-additives to the performance of diesel engine. The research stages include: extraction of citronella oil, vacuum fractionation of citronella oil, physical chemical characterization of citronella oil and its fractions, formulation of bio-additive -fuel blending, characterization of blending, and evaluation of fuel efficiency. The effect of concentration of the bio-additives was examined towards three diesel fuels; dexlite, pertamina-dex, and biosolar. The results showed two main fractions of citronella oil; citronellal dominant component (FA) and citronellol-geraniol dominant components (FB). The concentration variation of bio-additives was 0.1–0.5%. Fuel consumption efficiency was tested using diesel engine at an engine speed of 2000 rpm and a load increment of 1000, 2000 and 3000 psi with 7 min running time. The fractions represented the different tendencies to enhance the fuel efficiency up to 46%, influenced by the mixture’s concentration. Generally, citronella oil and the fractions showed the potency as bio-additive to diesel fuels.

Full textAbstract:
Abstract The main disease in cocoa pods is fruit rot caused by the fungi Phytophthora palmivora. The loss caused by P. palmivora is almost 90%. Currently, the control is still using synthetic fungicides which are harmful to humans and the environment. Therefore, the use of essential oils as fungicides is a safe control for the environment. This study aims to obtain a combination of nutmeg, cloves, and citronella that are effective as a botanical fungicide to control cocoa pod rot disease. The study was conducted at the Lampung State Polytechnic Plant Laboratory using a completely randomized design with 8 treatments which were repeated 5 times. The treatments tested were (1) negative control (water), (2) positive control (synthetic fungicide), (3) nutmeg oil, (4) clove oil, (5) citronella oil, (6) nutmeg + clove oil, (7) nutmeg oil + citronella, and (8) Clove and citronella oil. Essential oil testing on the growth of P. palmivora was carried out in vitro by inoculating agar pieces containing fungal culture on the surface of PDA containing essential oils. The results showed that all essential oil combination treatments were able to suppress the growth of the P. palmivora on PDA media. The combination of nutmeg oil and clove oil can suppress fungal growth by 77%, while the combination of nutmeg oil and citronella oil reaches 56.5% and the combination of clove oil and citronella oil reaches 27%. However, the single treatment that best suppressed the growth of P. palmivora was citronella oil, which was 32.8%.

Minyak atsiri dapat dijumpai di berbagai jenis tanaman yang tersebar di seluruh dunia. Indonesia setidaknya memiliki 40 jenis tanaman penghasil minyak atsiri komersial. Minyak atsiri memiliki berbagai manfaat, yaitu sebagai bahan baku kosmetik, obat-obatan, parfum, lilin, dan flavor. Salah satu atsiri yang diproduksi di Indonesia adalah citronella oil, citronella oil termasuk salah satu jenis atsiri yang populer digunakan sebagai anti-nyamuk, anti-jamur, dan anti-oksidan. Meskipun di Indonesia sudah berkembang luas petani yang berkebun serai wangi dan mengolahnya hingga menghasilkan minyak, akan tetapi masih banyak di antara mereka yang memproduksi citronella oil yang belum memenuhi standar. Oleh sebab itu, perlu adanya kajian mengenai faktor-faktor yang mempengaruhi kualitas citronella oil yang dihasilkan oleh usaha perseorangan agar dapat memenuhi standar industri. Untuk mengetahui kandungan citronella oil, dilakukan pengujian GC-MS. Hasil penelitian menunjukkan bahwa citronella oil yang dihasilkan memiliki kadar sitronellal yang lebih rendah dibandingkan industri besar, yaitu 11.37%. Sedangkan standar minimal untuk sitronelal adalah 35%, hal ini diduga berkaitan dengan umur panen, kualitas tempat tumbuh, kualitas mesin, dan pretreatment.

Essential oils from the stems of citronella and clove leaves contain chemical compounds, namely citronellal, eugenol, and geraniol, which function as mosquito killers. This study aims to make essential oils from fragrant lemongrass stems and clove leaves using the distillation method. Characteristic tests were carried out in the form of determining color, density, aroma resistance, and mosquito repellency of essential oils. The results of the color determination test showed that the essential oil from clove leaves was more brown in color and the density was greater than the essential oil from the citronella stem oil, while the durability of the aroma in the citronella oil was longer than that of the clove leaf oil. In testing the repulsion of mosquitoes, observations were made for 20 minutes to determine the number of dead mosquitoes, then the value of repulsion (DT) was calculated using probit analysis. The results of the mosquito repellent test showed that the DT value of the essential oil from the citronella stem was 60%-67%, the essential oil from the clove leaf was 54%-60%, while the mixture of the essential oil from the citronella stem and clove leaf was 67%-80 %. This shows that the essential oil from a mixture of citronella stems with clove leaves is able to kill mosquitoes better than only essential oils from citronella stems or clove leaves.©2020 JNSMR UIN Walisongo.

Lemongrass is an herbal plant with the Latin name Andropogon nardus L. In Indonesia alone, lemongrass is widely cultivated. Not only as a flavoring in cooking, citronella is also a plant that produces atsiri oils. The chemical components contained in citronella are quite complex, but the most important are citronella and geraniol, as determinants of odor intensity, fragrance, and the value of the price of citronella oil. Not only the benefits of citronella can be taken, the waste from citronella can also be utilized. One area that produces citronella is Pendalian Village, Rokan IV Koto District, Rokan Hulu Regency, Riau. The owner of the garden directly carries out the production process and markets it to collectors, but since the COVID-19 pandemic, the price of citronella oil has dropped drastically and is difficult to market. The data collection method is carried out with partner site analysis and surveys. With this service, it is hoped that the owners of the lemongrass gardens in Pendalian Village can overcome the processing and marketing of citronella oil production, so that it can trigger the economic development of Pendalian Village.

This paper adopts the precise vapor-liquid phase equilibrium instrument to collect the binary system of citronellal-citronellol, citronellal-geraniol and citronellol-geraniol with the absolute pressure of 1.2kPa. Meanwhile, the corresponding phase equilibrium diagrams are drawn, which provide data support for the distillation of citronella oil.

<p>The <em>Aedes aegypti</em> mosquito can develop an immune system against the insecticide used. Control efforts with the use of insecticides are no longer effective if the target insects have become resistant. So there needs to be an effort to overcome the insect resistance that is targeted. Citronella grass is an herbal plant that can be used as an ingredient in vegetable pesticides. The leaves and stems are distilled to produce essential oil known as citronella oil. This research is about studying the effects of citronella oil against the resistance of the vector carrier for dengue fever, namely <em>Aedes aegypti. </em>The detection of citronella essential oil (<em>Cymbopogon nardus</em> L.) by Thin Layer Chromatography showed a reduction in UV<sub>254</sub> visualization (Rf 0,68). The resistance test showed that the mortality percentage of adult mosquitoes <em>Aedes aegypti</em> exposed to 0.03% alphacymethrin was 73,7% resistant criteria (<90%). The mortality percentage of adult mosquitoes <em>Aedes aegypti</em> exposed to Alphacypermethrin (0,03%) and citronella oil was 2,5% each; 5%; 7,5% and 10% with treatment time 15 respectively, namely 18,7%, 50,7%, 70,7% and 82,7%; the treatment time of 30 minutes consecutively is 62,7%, 89,3%, 96% and 97,3% and the treatment time is 60 minutes respectively, namely 93,3%, 98,7%, 98,7% and 100%. There was an increase in the percentage of mosquito deaths exposed to the combination of alphacypermethrin and citronella oil, compared to those without citronella oil, this indicates that mosquitoes are more susceptible and resistance has decreased due to exposure to citronella oil. <strong></strong></p>

The fruit borer (Helicoverpa armigera Hubner) is one of the key pests of chili pepper in Indonesia. Yield loss due to this insect pest may reach up to 60%. Chemical treatment for con-trolling this insect pest is ineffective and eventually leads to environmental pollution. More environmentally safe insecticides are developed based on natural plant ingredients as their active compound such as essential oils. This study aimed to assess the potential of citronella oil for managing H. armigera on chili pepper. The experiments were conducted at the Indonesian Vegetables Research Institute from April 2009 to March 2010 and in Cirebon, West Java from November 2009 to March 2010. A field experiment was designed in a randomized complete block design with five treatments and replicated five times. Citronella oil was extracted by steam distillation from Cymbo-pogon nardus. The oil was then chemically characterized by using GC-MS and its efficacy (ovicidal and feeding deterrent) against H. armigera was tested both in laboratory and field conditions. The GC-MS result showed that major chemical compounds of the citronella oil used were citronella (35.97%), nerol (17.28%), citronellol (10.03%), geranyle acetate (4.44%), elemol (4.38%), limonene (3.98%), and citronnellyle acetate (3.51%). The laboratory experiment revealed that the highest concentration (4,000 ppm) of citronella oil reduced egg laying by 53-66%. Ovicidal activity was concentration dependent, and egg hatchability decreased by 15-95% compared to control. The field experiment showed that treatment of citronella oil at 2.0 mL L-1 significantly reduced fruit damage by H. armigera similar to the plots treated with spinosad at the recommended dose (60 g ai ha-1). Application of citronella oil significantly reduced fruit damage by 72% and increased quality of the chili pepper. Because oviposition and feeding deterrent properties are key factors in controlling the pest, therefore this study revealed that citronella oil has potential to be incorporated into the controlling program of H. armigera on chili pepper.<br /><br /><br />

Essential oils are volatile aromatic compounds produced by plants. Essential oils are known by various names, including ethereal oils because they have ether properties, volatile oils because they evaporate easily at room temperature, and essential oils because they contain the essence of a plant. Lemongrass is one of the plants that produce essential oils. Extraction of citronella oil can use several methods such as hydrodistillation, pressing, solvent extraction, and adsorption by vaporizing solid fat (enfleurage). In this study the method that will be used is hydrodistillation. This study aims to determine the effect of the mass ratio of citronella oil to the volume of solvent, namely aquadest, on the yield of citronella oil and to determine the effect of the length of extraction time required on the yield of citronella oil.

Abstract By planting citronella, the community has historically and culturally promoted citronella oil production for decades (Cymbopogon nardus L). The most common energy sources for distillation are distillation waste and firewood. The completion energy distillation of citronella oil is becoming more challenging as it becomes more difficult to obtain firewood and the price increases. This limitation renders citronella oil production untenable. For the distillation process, alternative energy sources with the attributes of Consolidated, Continue, Controllable, Clean, and Affordable are introduced, in this case, an electromagnetic power generator energy source. The research was carried out at Sirna Jaya Village, Gunung Halu District, West Bandung Province. The Electromagnetic Power Generator consists of three major components: 1. Starter for beginning rotation; 2. Electromagnet Guider for controlling the repulsion force between comparable magnetic poles, which is subsequently transferred to kinetic energy; and 3. Generator for producing electrical energy. It has been demonstrated that the power generator innovation can create 1500 watts of electrical energy and be scaled up. It has been demonstrated that the Electromagnetic Power Generator is a valuable energy source for processing citronella oil.

A preparation of essential oils to control chicken lice (Menopon gallinae) and mites (Ornithonyssus bursa) was developed. Each essential oil was effective against lice and mite in vitro. Citronella oil at the lowest concentration of 0.208 µg/cm2 resulted in a mortality rate of 100% in chicken lice, whereas a higher concentration of cloves, lemongrass, ginger, Makwan oil (0.416 µg/cm2), and Litsea oil (0.832 µg/cm2) was also found to be effective. A 100% rate of mortality for mites was observed using citronella and ginger oil at a concentration of 0.416 µg/cm2. At the same concentration, cloves, lemongrass, Litsea, and Makwan oil exhibited mortality rates in mites of 77.96%, 93.33%, 87.30%, and 93.49%, respectively. The efficacy of citronella oil and ginger oil against lice and mites was further examined in vivo. Citronella and ginger oil affected the rate of decline in lice from day 1 to day 14, whereas the number of mites living in nests declined from day 1 to day 7. The reduction of these parasitic insects may be correlated with the chemical constituents present in each essential oil. The active ingredients likely acted insecticidal agents against both parasitic insects. Moreover, the preparation developed here did not cause any side effects, such as dermatitis and respiratory disorders, during animal trials. Hence, preparations comprised of the essential oils of citronella and ginger can be further developed and used as insecticidal agents to control and/or eliminate chicken lice and mites on commercial farms.

One of the problems in papaya cultivation is the high attack of pests and diseases. The mealybug, P. marginatus L (Hemiptera: Pseudococcidae) is currently found to attack papaya plants. The infestation of mealybugs greatly affects the yield and quality of fruits. The purpose of this study was to determine the effect of the concentration of citronella oil on mealybugs on papaya plants. The study for the observation of mortality and fecundity used a Randomized Block Design (RAK), with 4 treatment levels of citronella oil concentration, namely 0 (control), 0.5 mL/L, 1 mL/L and 2 mL/L. Observation parameters included preference level of papaya mealybugs on the aroma of citronella oil, repellency, fecundity and mortality of mealybugs, with the application of citronella oil. The results showed that citronella oil has the potential to be used to control papaya mealybugs. The application of citronella oil at concentrations of 0.5, 1 and 2 mL/L showed repellent activity against mealybugs, reducing fecundity and causing mortality. The higher the concentration of citronella oil applied, the more potential to control mealybugs. However, the application of citronella oil must be considered for its impact on plants. Too high a concentration can cause toxicity to plants.

Java citronella (Cymbopogon winterianus Jowitt) is an important perennial aromatic grass cultivated in different parts of India. The steam-volatile essential oil from the citronella herb is widely used in perfumery, in manufacture of deodorants and mosquito repellent creams and in flavouring beverages. Systematic cultivation of this crop is being taken up and application of large quantities of N fertilizers was found to increase yield (Narayana et al. 1975; Bommegowda, 1978; Singh, Pathak & Bodoloi, 1980; Prakasa Rao et al. 1983). However, the efficiency of N utilization by this crop was found to be quite poor (Prakasa Rao et al. 1983). No systematic data are available in India on the effect of harvest season and N fertilizers on the principal constituents of citronella oil. Therefore the present experiment was made with two objectives: (i) to determine the effect of harvest season and N fertilizers on the essential oil concentration and the principal constituents of the oil which determine the oil quality, and (ii) to determine the effect of neem cake, an indigenous cheap material which is reported to have nitrification inhibitory properties, on the herb and essential oil yields of citronella.

Full textAbstract:
Introduction: The comprehensive research on the chemical composition of citronella grass led to various advantages, including the development of analytical tools for quality evaluation, which is the primary reason the plant is cultivated. Attacks by pests such as stink bugs, brown planthoppers, grasshoppers, ladybugs, and aphids are the most significant threat to crop productivity. Other problems include grasshoppers. This assault slows the development of the rice plants, resulting in a decrease in productivity or possibly preventing harvesting altogether. Applying chemical pesticides may help minimize the number of illnesses and pests. Using chemical pesticides over an extended period, on the other hand, may wreak havoc on the environment. Objective: This review aims to examine the biological & insecticidal effectiveness of citronella oil, which can help to understand to use of this oil to control insects and mosquitos. Method: Multiple computerized databases, such as PubMed, Google Scholar, ScienceDirect, etc., were used to write the paper. Result. The medicinal benefits of Citronella oil have been extensively documented, and the oil's components have been well studied. Citronella oil has been used as an antifungal, antiparasitic, effective insect repellent, and antibacterial, thanks to extensive research into its medicinal potential. Conclusion: Oil of citronella contains citronellol, citronellal, and geraniol. If they enter the environment, some will vaporize. In water, they evaporate slowly. Once vapours are airborne, their half-lives range from 38 minutes to 3.2 hours. Instead, microbes degrade citronellol and geraniol.

This study was conducted to evaluate some terpenes effect on the behavior and immune function of hemocytes in adults of the red palm weevil Rhynchophorus ferrugineus. Six individual different terpenes these are: (±)-menthol, B-citronellol, ( + )-3-carene, (R)- ( + )- limonene, citronella oil and orange terpenes. The results revealed significant differences between the terpenes used on the olfactory response on this insect, in that half of the compounds were very attractive while the other half were repellant to them. This behavior study results with olfactometer citronella oil exhibited an 80% attraction response rate for both sexes, while menthol exhibited a 60% attraction response rate for females and 100% for males. By contrast, menthol had a more significant effect on adults than citronella, lethal concentration at 50 scale (LC50) values of 1.03, 0.89, and 0.9 mg, and LC95 values of 5.09, 2.01, and 1.59 mg, after 24, 48 and 72 h, respectively. For citronella oil, the LC50 values were 2.09, 1.76, and 1.70 mg after 24, 48, and 72 h, and the LC95 values were 5.5, 3.7, and 1.5 mg after 24, 48 and 72h, were noted. In the present study, the effects of citronella and methanol insecticides were observed on six types of hemocytes namely prohemocytes, granulocytes, plasmatocytes, oenocytes, coagulocytes and spherulocytes. Both citronella oil and menthol had a histopathological effect on the hemocytes of the adult red palm weevil, specifically, on the cell membrane, cytoplasm, and nucleus. The findings also revealed that the vacuoles in some hemocytes, specifically, the prohemocytes, plasmatocytes, and granulocytes were more sensitive than those in other hemocytes, which remained unaffected by the treatment. The effects of citronella and menthol on RPW immunity were demonstrated in this study, and this information may be applied to their usage in integrated pest control at sub-lethal dosages.

Full textAbstract:
Laboratory assays were conducted to evaluate deterrency and contact toxicity of six essential oils to the Argentine ant, Linepithema humile (Mayr), and the red imported fire ant, Solenopsis invicta Buren. In choice tests, both Argentine ants and fire ants crossed barriers treated with multiple rates of basil, citronella, lemon, peppermint, or tea tree oil less frequently than paired control barriers. Eucalyptus oil did not prevent movement of either species at any of the rates tested. In continuous exposure assays, citronella oil killed 50% of Argentine ants in 34.3 min and was the only treatment to cause 100% Argentine ant mortality after 24 h. Argentine ant mortality after 24 h was 89.8% with peppermint oil and 85.7% with tea tree oil, with the remaining treatments having mortality not significantly different from the control. Only citronella oil caused significant mortality of red imported fire ants, with 50.6% of the ants being dead after 24 h of continuous exposure.

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.

A field experiment was conducted for 2 years (1993–95) at Central Institute of Medicinal and Aromatic Plants, Field Station, Bangalore, India to evaluate the nitrification inhibitors, benzotriazole, o-nitrophenol, m-nitroaniline and dicyandiamide in a perennial aromatic grass, Java citronella. Citronella responded to applications of high doses of nitrogen (300 kg N/ha/year). The interaction between N doses and nitrification inhibitors was significant. Nitrification inhibitors performed better at the highest N dose (450 kg N/ha/year) and the increase in the essential oil yields was to an extent of 27·3 to 34·6% when compared with ‘N alone’ treatment. The nitrification inhibitors also increased the apparent N recoveries by citronella considerably. The oil content in the herb and its quality were not affected by the treatments. The nitrification inhibitors increased citronella yields and improved N economy.

The consumption of diesel fuel in Indonesia is increasing every year, one way to overcome this problem is to use natural bioaditive in the form of essential oils found in Indonesia. Essential oils used in this study are fragrant lemongrass because fragrant lemongrass contains carboxylic compounds (-COOH) [1,2,3]. With the aim of improving engine performance and reducing fuel consumption. This research was conducted by mixing fragrant citronella oil with diesel oil with a percentage of 1%, 0.5% and 0.1% of the total volume. Diesel engines are operated with variations in loading 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 W at a constant engine speed of 1500 rpm. The variables measured and calculated in this experiment are power, torque, Break Mean Effective Pressure (BMEP), Specific Fuel Consumption (SFC). The results showed that adding citronella oil to diesel fuel with a percentage of 1%, 0.5% and 0.1% significantly reduced fuel consumption by 15.5%, 3.6% and 2.6% respectively. The maximum reduction in fuel consumption reaches 0.055 liters / hour at 200W loading with a bioaditive level of 0.1%. The next study planned is to mix clove oil and citronella oil as bioaditive so that it is expected to reduce fuel consumption and engine corrosion.

Characterization and catalytic activity of modified natural zeolite for the conversion of citronella oil to menthol was investigated. In this research, natural zeolite was prepared by acid activation with HCl and impregnated with Ni metal. The addition of Ni metal of around 12.5 nm in diameter provided a bifunctional catalyst for two steps of citronella oil conversion i.e. cyclization and hydrogenation. The process was performed in a one-pot reaction system by stirring at 200oC with pressure of 20 bar H2 for 3h. The reaction products changed slightly with varieties of reaction temperature and amount of catalysts employed. Results showed that Ni/NZB-HT catalyst was the best catalyst which was able to convert citronella oil to menthol with a selectivity of 50% menthol and 100% conversion of citronellal.

To confirm that Korean Food and Drug Administration (KFDA) guidelines are applicable to test the efficacy of mosquito repellents, these guidelines were used to test the efficacy and complete protection times (CPTs) of three representative mosquito repellents: N,N-diethyl-3-methylbenzamide (DEET), citronella, and fennel oil. The repellency of citronella oil decreased over time, from 97.9% at 0 h to 71.4% at 1 h and 57.7% at 2 h, as did the repellency of fennel oil, from 88.6% at 0 h to 61.2% at 1 h and 47.4% at 2 h. In contrast, the repellency of DEET remained over 90% for 6 h. The CPT of DEET (360 min) was much longer than the CPTs of citronella (10.5 min) and fennel oil (8.4 min). These results did not differ significantly from previous findings, and hence confirm that the KFDA guidelines are applicable for testing the efficacy of mosquito repellents.

In Indonesia, in general, it has a very abundant natural resource potential, one of which is lemongrass. Lemongrass is still not widely cultivated in Indonesia, this plant is processed and processed into essential oils, it will get a high selling value. Currently, the development of essential oils is a considerable concern of the Indonesian government. Of the various raw materials for making essential oils, one of the raw material plants for essential oils in Indonesia that is good to be developed is citronella. The purpose of this study was to examine experimentally the manufacture of citronella oil (Citronella oil) from the leaves and stems of citronella. Citronella oil is generally used for health, ranging from bacteria and fungi, headaches, to hypertension and is also used as aromatherapy. The advantage of the fractionation column method is the process of separating the components from the Constituent substances of a mixture of solution compounds based on the difference in boiling points by using multilevel distillation, so as to produce good quality essential oils with low water content. From three Tests of essential oil distillation apparatus with fractionation column of citronella, the results of the first test is as much as 940 ml with a mass of 920 gr and a density of 978.2 kg/m3, the second test results obtained as much as 80 ml with a mass of 70 gr and a density of 875 kg/m3, the third test results obtained as much as 70 ml with a mass of 50 gr and a density of 714.2 kg/m3. The average density from the first to the third Test was 855.8 kg / m3. The combustion temperature in the reactor tank is very influential on the duration of combustion and the number of results that come out and the quality of the results obtained.
