ABSTRACT
Citronella oil is a non-timber forest product (NTFP) and is commercially obtained from the distillation of citronella leaves (Cymbopogon nardus L).
Fragrant citronella leaves are one of the raw materials for obtaining vegetable oils in the form of essential oils.
Essential oil is the main component consisting of composition in the form of geraniol and citronellal.
The process of extracting essential oils can be done using various methods, one of which is the Vacuum Hydrodistillation method.
The Vacuum Hydrodistillation method is carried out using a vacuum pump as a pressure guard and the boiling point of the distillation process does not exceed the boiling point temperature of water, which is 1000 C, so that the oil produced is maintained its purity.
The vacuum hydrodistillation process of citronella was carried out for 3, 5, and 7 hours with each treatment using random and whole pieces of raw The resulting essential oil products were analyzed in the form of yield, density, refractive index and oil composition analysis using GC-MS.
The best essential oil yields from citronella were obtained under operating conditions with random samples and distillation time of 5 hours.

Limited public knowledge regarding the processing of refining citronella oil is the main key cause for the decline in the quality of citronella .
According to a report from the Ministry of Trade .

The low production of citronella oil can further increase the value of citronella oil with the presence of derivative products from this oil.

RESEARCH METHODOLOGY
The raw material used is fragrant While the equipment used is a set of vacuum hydrodistillation tools, refractometers, pycnometers, measuring pipettes.
Erlenmeyer and a set of 50 ml titration tools.
25 liters of water is put into the distilled kettle.

10 kg of prepared citronella leaves with whole size and random pieces are put into the distilled The pump is turned on to circulate the cooling water, then the heater is turned on until it reaches a temperature of 100oC and then the distillation process is carried out by varying the boiling time.
Variation of boiling time is 3.
5 and 7 hours.
During the boiling process, the steam from citronella leaves will be cooled using cooling water.
So the oil will come out through the condenser.
After the distillation process is complete, the yield of the oil obtained is calculated and the quality of the essential oil is analyzed.

2 The Effect of Distillation Time on the Density of Essential Oils Yield From the graph above it can be seen that the distillation time affects the density of the essential oil obtained, where the longer the distillation time the lower the density of the oil.
And for the best density value, it was found in samples with random pieces and 5 hours of distillation time, which was 92735 gram/ml.

3 The Effect of Distillation Time on the Refractive Index of Essential Oils From the research that has been done, it is known that the highest oil yield was obtained from the vacuum hydrodistillation process with random sample pieces and 5 hours of distillation time, which is equal to This is because the samples that were randomly cut have a smaller size than the whole pieces the more surface area, so the oil will be easier to extract.
From the graph of the relationship between distillation time and the value of the refractive index of the essential oil samples, it can be seen that the distillation time has an effect on the refractive index.
Where the longer the refining time, the lower the refractive index.
This is because the longer the oil is extracted at a certain temperature, the components of the essential oil will be damaged, so that the value of the refractive index decreases.
While the comparison between the size of the intact sample and the random section, it was found that the index of refraction in the Jurnal Reaksi (Journal of Science and Technolog.
