Pogostemon Cablin

Tanaman nilam (Pogostemon cablin Benth.) merupakan salah satu tanaman penghasil minyak atsiri atau yang lebih dikenal dengan nama Patchouli Alcohol (PA). PA merupakan senyawa yang terbesar di dalam minyak nilam sebagai penentu mutu minyak nilam, kadar PA dalam minyak nilam menurut SNI 06-2385-2006 yaitu minimal 30%. Sampel minyak nilam yang digunakan adalah minyak nilam yang berasal dari Aceh Tamiang. Tujuan penelitian ini dilakukan untuk mengetahui kadar PA sebelum dan sesudah adsorbsi menggunakan Nanomontmorillonite (Nano-MMT) sebagai adsorben dengan menggunakan metode kualitatif dengan uji warna dan metode kuantitatif dengan analisis Gas Cromatography Mass Spectrometry (GC-MS) untuk menentukan kadar PA, mengingat Nano-MMT adalah jenis tanah liat (clay) yang dapat digunakan sebagai adsorben yang mengadsorpsi kontaminan metalik dengan baik dikarenakan Nano-MMT mempunyai muatan negatif yang dapat mengikat spesies yang bermuatan positif kontaminan metalik seperti logam berat. Berdasarkan hasil analisis diketahui bahwa kadar PA sebelum diadsorpsi 7,74% b/v, dan kadar PA setelah diadsorpsi berkisar antara 4,47%-7,86% b/v, kadar tersebut belum sesuai dengan SNI. Hal ini disebabkan karena banyak hal diantaranya terdapat komponen pengotor berupa kontaminan metalik seperti logam, terjadinya oksidasi, tercampurnya minyak nilam dengan bahan lain, pencemaran wadah penyulingan minyak, dan waktu penyimpanan yang relatif lama.

Bemisia tabaci is one of the red chili pests that plays a role as a Begomovirus vector. This vector can be controlled through Integrated Pest Management (IPM) practices. One of the potential practices is by utilizing corn as a barrier crop to prevent the vector from attacking the main crop. The aim of this research was to examine the repellence activity of the volatile compound obtained from various ages of corn crop against B. tabaci. The volatile compound was collected from the corns at 4 week after planting (WAP), 6 WAP, 8 WAP, 10 WAP, and 12 WAP. Volatile compound capture device was designed with two solvents, i.e. hexane and ethanol, then the volatile compound analyzed by Gas Chromatography Mass Spectrometry (GC-MS). B. tabaci repellency against volatile compound was examined using Y-tube olfactometer. Each treatment was employed with 5 replications. Data were analyzed using ANOVA with 95% and further analyzed by Least Significant Different (LSD). The parameter observed was the total of B. tabaci avoided the volatile compound tested until half of the control olfactometer arm. The results showed that all ages of the corn produced repellent compound and the most optimal were corn aged 12 WAP with repellency rate of 83.72%. GC-MS analysis identified the volatile compound were citronella, limonene, β-phellandrene, β-caryophyllene, 1.8 cineole, farnesol, caryophyllene, and patchouli alcohol.

Pogostemon Cablin

This research aims to isolate oil from patchouli (Pogostemon cablin Benth) and identify the chemical components of patchouli oil using Gas Chromatography-Mass Spectrometry (GC-MS). Patchouli plant samples were obtained from Welulu Village, Kolaka Regency, Southeast Sulawesi Province. Fresh patchouli leaves are dried in the sun for four days to a constant weight. Patchouli leaves water content is 77.41% (w/w). Dry patchouli leaves are distilled using the water and steam method for two hours. Water and oil distillates are separated using a separating funnel. Patchouli oil obtained was dried using Na2SO4 anhydrous and yield 0.73% (w/w). The results of GC-MS analysis showed that patchouli oil contained 13 chemical components compounds, namely β-patchoulene (4.56%), cedr-8-ene (1.24%), trans-caryophyllene (7.96%), α-guaiene (18.61%), seychellene (5.70%), patchoulene (2.88%), eremophilene (1.33%), azulene (8.74%), delta-guaiene (18.90%), cyclohexanone (1.10%), globulol (1.88%), veridiflorol (4.39%), and alcohol patchouli (22.7%).
