Abstract
Tujuan penelitian ini adalah menganalisis pengaruh gelombang ultrasonik pada
metode Microwave Steam Diffusion (MSDf) terhadap penggunaan energi, serta yield dan
kadar minyak jeruk yang dihasilkan. Selanjutnya, membuat produk obat pengusir
nyamuk dari ekstrak minyak jeruk sebagai alternatif obat pengusir nyamuk yang aman
bagi tubuh dan praktis.
Pada penelitian ini dilakukan proses ekstraksi dari kulit jeruk manis. Proses
ekstraksi ini dilakukan dengan 2 metode yaitu microwave steam diffusion (MSDf) dan
microwave ultrasonic steam diffusion (MUSDf). Pada tahap MSDf, kulit jeruk kering
(kadar air 10%) ditimbang masing-masing 250 gram, kemudian dimasukkan ke dalam
labu leher 3 dan menambahkan air sebanyak 300 mL. Kemudian dilakukan proses
ekstraksi dengan microwave pada suhu 100oC pada tekanan 1 atm. Sedangkan pada
tahap MUSDf, kulit jeruk kering yang sudah ditimbang dimasukkan kedalam gelas beker
dan ditambahkan air sebayak 220 mL. Dilanjutkan dengan proses ekstraksi ultrasonik
selama 30 menit. Kemudian setelah melalui proses ekstraksi ultrasonik dilanjutkan
dengan proses ekstraksi microwave seperti pada tahap MSDf.
Dari hasil penelitian yang telah dilakukan, didapatkan bahwa metode yang terbaik
untuk menghasilkan ekstrak minyak jeruk dari limbah kulit jeruk manis (Citrus
auranticum) adalah dengan menggunakan metode MUSDf. Hal ini dikarenakan yield
yang dihasilkan pada waktu 30 menit pada metode MUSDf sebesar 0,204% lebih besar
dibandingkan metode MSDf sebesar 0,179 %. Sedangkan kadar minyak jeruk yang
didapatkan dari metode MUSDf sebesar 73,163 % dan MSDf sebesar 69,09%. Selain itu,
metode MUSDf dapat mempercepat waktu ekstraksi selama 33,3% dan konsumsi energi
yang lebih rendah 30% dibandingkan dengan MSDf. Berdasarkan hasil uji efektivitas
lotion anti nyamuk didapatkan persentase daya tolak nyamuk untuk lotion minyak jeruk
sebesar 85,7% lebih baik dibandingkan dengan autan sebesar 64,2% Berdasarkan hasil
uji organoleptik terhadap lotion anti nyamuk yang dihasilkan, didapatkan aroma, warna,
tekstur, serta kelembaban yang cukup baik
========================================================================================================================The purpose of this study was to analyze the effect of ultrasonic waves on Microwave
Steam Diffusion (MSDF) on energy usage, as well as yield and oil content of oranges
produced. Furthermore, making mosquito repellent products of citrus oil extracts as an
alternative mosquito repellent that is safe for the body and practical.
In this study the extraction process is done from sweet orange peel by two methods,
namely microwave steam diffusion (MSDF) and microwave ultrasonic steam diffusion
(MUSDf). At this extraction of the MSDF, dried orange peel (moisture content 10%)
weighed 250 grams each, then put in a 3-neck flask and add water up to 300 mL. Then do
the extraction process with microwave at 100 ° C and 1 atm for pressure. Whereas MUSDf,
dried orange peel that has been weighed inserted into the glass beaker and added 220 mL
of water. Followed by ultrasonic extraction process for 30 minutes. Then, after going
through the process of ultrasonic extraction followed by microwave extraction process like
extraction procces of the MSDF.
From this research, it was found that the best method to produce extracts of citrus
oils from sweet orange peel waste (Citrus auranticum) is using MUSDf. This is because
the yield is generated at the time of 30 minutes at MUSDf method amounted to 0,204%
higher than the MSDF methods of 0,179%. While the levels of orange oil obtained from
MUSDf methods of 73,163% and amounted to 69,09% MSDF. Besides, the method can
accelerate the extraction time of MUSDf amount 33,3% and lower energy consumption of
30% compared to the MSDF. Based on the test results of the effectiveness of anti-mosquito
lotion percentage obtained for the thrust mosquito lotion orange oil amounted to 85,7%
better than the Autan of 64.2% based on the results of the organoleptic test repellents
produced, obtained aroma, color, texture, and moisture.
