KESIMPULAN DAN SARAN
5.1 Kesimpulan
Pada penelitian mengenai pengaruh metode ektraksi terhadap persentase yield minyak biji pepaya dapat ditarik beberapa kesimpulan, yaitu:
1. Waktu pengeringan biji pepaya yang dibutuhkan pada temperatur 70°C adalah 420 menit.
2. Kandungan air akhir pengeringan biji pepaya sebesar 7,6%.
3. Kurva pengeringan kinetik biji pepaya sesuai dengan persamaan overhults.
4. Metode ekstraksi terbaik untuk mendapatkan persentase yield minyak terbesar yaitu ekstraksi soxhlet sebesar 28,35%.
5. Variasi temperatur dan waktu terbaik untuk mendapatkan persentase yield minyak terbesar menggunakan ekstraksi pelarut yaitu sebesar 50°C, 24 jam dengan yield minyak sebesar 27,24%.
6. Variasi temperatur terbaik untuk mendapatkan persentase yield minyak terbesar menggunakan ekstraksi superkritik CO2 pada 200 bar yaitu sebesar 80°C dengan yield minyak sebesar 7,2%.
5.2 Saran
Setelah diperoleh hasil penelitian mengenai pengaruh metode ektraksi terhadap persentase yield minyak biji pepaya, maka dapat diajukan beberapa saran untuk pengembangan topic tersebut lebih lanjut. Saran tersebut yaitu:
1. Perlunya penelitian lebih lanjut mengenai analisa kandungan minyak biji pepaya yang diperoleh dari setiap metode ekstraksi.
2. Perlunya penelitian mengenai kandungan heksana yang masih tertinggal pada minyak hasil ekstraksi soxhlet dan pelarut.
3. Perlunya pengembangan ekstraksi superkritik CO2 dengan menggunakan ko- solvent untuk memperbesar persentase yield minyak dari biji pepaya.
4. Perlunya dilakukan pengambilan minyak yang masih tersisa pada reaktor dengan cara melarutkan menggunakan heksana.
5. Perlunya dilakukan penentuan waktu optimum pada ekstraksi superkritik CO2.
