Abstract

Black pepper is one of Indonesia's agricultural commodities, contributing foreign exchange to the country. However, the economic value of this commodity has decreased. It is influenced by the lack of diversified black pepper products, which of course, have a higher value than raw material marketing. One product diversification that can be developed is black pepper oil. In obtaining essential oils, appropriate methods and technology are needed so that the resulting product is of high quality and the process is carried out efficiently. The latest methods in extraction that are being developed are microwave and ultrasonic technology. Therefore, in this study, black pepper oil extraction was carried out using the microwave hydrodistillation method, whereas previously, ultrasonic pretreatment was given for the material. In this case, observations were made on the influence of extraction parameters. Based on the research, it was found that increasing the distiller size flask and ambient temperature could increase the percentage of essential oils yield. At the same time, the longer extraction time caused a decrease in yield. Decreasing the material particle size and increasing microwave power could cause an increase in yield up to a certain point. The best results in black pepper oil extraction were obtained under extraction conditions using a distiller size of 1000mL, extraction time of 60 minutes, at an ambient temperature of 30 oC, the particle size of 60 mesh, at a power of 450 W with a yield of 1.056%, with the characteristics of having a clear greenish colour and anRI of 1.480. These specifications comply with ISO 3061:2008 for essential oil from black pepper. Thus, these parameters can be considered in the black pepper oil extraction process to produce marketable products. As a suggestion for further research, modeling, and process scale-up can be developed.

Abstract

Piper nigrum l. atau lada hitam, merupakan tanaman asli Indonesia yang juga tumbuh di Malaysia, Sri Lanka, Vietnam dan negara Asia Tenggara lainnya. Lada hitam dapat diolah sebagai oleoresin dengan melakukan ekstraksi. Ultrasound-Assisted Extraction adalah metode untuk meningkatkan hasil dan efisiensi ekstraksi oleoresin. Tujuan dari penelitian ini yaitu untuk mengkaji pengaruh waktu dan suhu ekstraksi terhadap rendemen, densitas, dan indeks bias, mengkaji komponen kimia oleoresin lada hitam serta mengkaji hasil relatif terbaik sesuai SNI 01-0025-1987-B. Bubuk lada hitam diekstraksi dengan ultrasound menggunakan pelarut etanol Rasio bahan dan pelarut yang digunakan adalah 0,37 b/v. Kondisi operasi dilakukan pada waktu ekstraksi 20, 35, 50, 65, dan 80 menit serta suhu ekstraksi 30, 40, 50, 60, dan 70 ˚C dan frekuensi 40 kHz. Hasil dari penelitian menunjukkan pengaruh waktu ekstraksi yang semakin lama dan suhu ekstraksi yang semakin tinggi maka rendemen, densitas, dan indeks bias yang dihasilkan akan semakin besar. Hasil relatif terbaik diperoleh pada waktu ekstraski 80 menit  dan suhu 70˚C dengan warna coklat pekat, berbentuk pasta cair, beraroma khas lada, rendemen sebesar 22,57%, densitas sebesar 0,8350 gram/ml, kadar piperin sebesar 74,78%, kadar minyak atsiri sebesar 25,22%, dan indeks bias sebesar 1,4900.
