Abstract

Eucalyptus oil is an essential oil popular in Indonesia due to its ability to treat flatulence, induce a sense of warmth, and serve as an antibacterial, antiviral, antifungal, and aromatherapy agent. Melaleuca cajuputi is a species of eucalyptus plant that yields eucalyptus oil. This plant is commonly found in Central Maluku and West Nusa Tenggara. The distilling process of eucalyptus oil took four hours and involved using steam distillation. Several physical parameters, including cineole content, oil weight, specific gravity, optical rotation, and ethanol solubility, were utilized to evaluate the grade of the produced eucalyptus oil. The analysis of physical properties was conducted using SNI 06-3954-2006-compliant methodologies. The volatile compounds of eucalyptus oil were analyzed using the Gas Chromatography-Mass Spectrometry (GC-MS) technique. The test results indicated that the purity of eucalyptus oil from Maluku and NTB specifically met the requirements of SNI 06-3954-2006. GC-MS measurement revealed that eucalyptus oil from Maluku, with a yield of 1.42%, contained 26 chemical components, with 1.8-cineole comprising the highest percentage at 67.38%. In contrast, the yield of NTB eucalyptus oil was 1.84%, and it contained 21 volatile compounds of which the compound of 1.8 cineole made up 66.58% of the component composition

Abstract

Pepper is one of the agricultural commodities that Indonesia widely exports. Pepper can be processed into various products, including essential oils. Pepper essential oil can be extracted using several methods, including the microwave. This method can speed up the essential oil extraction process. Optimization was carried out using the Box-Behnken design using the three independent parameters: solution ratio, time, and microwave power. The upper and lower limits used for the independent variables are solvent amount of 1,350 mL and 750 mL, time of 90 minutes and 60 minutes, and microwave power of 440 watts and 136 watts. The optimal data generated is treatment with a solvent amount of 1,050 mL, 90 minutes, and 440 watts of power, resulting in validation data of 99.046%. The optimal essential oil treatment gives a specific gravity of 0.8281, a refractive index of 1.4824, solubility in ethanol 1:2, acid number 0.739 mg KOH/g, ester number 19.599 mg KOH/g, and a hue value of 186,38 (green). Oil with optimum treatment also has an IC50 antioxidant activity of 32,919.9 ppm. Keywords: Antioxidant; Extraction; Microwave; Pepper; RSM.

Abstract

Pala (Myristica fragrans) merupakan salah satu komoditas perkebunan unggulan Indonesia dengan nilai ekspor yang cukup tinggi dan prospek pasar yang terus meningkat. Biji pala banyak dimanfaatkan pada berbagai bidang, mulai dari industri pangan sebagai bahan penyedap dan flavoring, industri farmasi sebagai komponen obat tradisional, hingga industri kosmetik. Meskipun demikian, dalam beberapa tahun terakhir sejumlah negara tujuan ekspor menolak pengiriman pala Indonesia karena kadar aflatoksin yang terdeteksi melebihi ambang batas maksimum yang diizinkan. Aflatoksin umumnya terbentuk akibat kontaminasi jamur selama proses panen maupun pascapanen, terutama ketika kondisi kadar air tidak terkendali. Proses pengeringan yang kurang optimal dan penyimpanan yang tidak sesuai seringkali meningkatkan kadar air biji pala sehingga menciptakan lingkungan yang mendukung pertumbuhan kapang penghasil aflatoksin. Oleh karena itu, penentuan kadar air kesetimbangan dan kondisi penyimpanan yang tepat melalui pendekatan sorpsi isotermis sangat penting untuk meminimalkan risiko kontaminasi. Penelitian bertujuan mengidentifikasi kondisi penyimpanan optimal yang mampu mencegah pertumbuhan mikroorganisme penghasil aflatoksin pada biji pala. Metode yang digunakan adalah eksperimen dengan menentukan Kurva Sorpsi Isotermis menggunakan larutan garam jenuh NaOH, CH3COOK, MgCl2, Kl, NaCl, KCl, BaCl2, pada berbagai tingkat aktivitas air. Data hasil pengukuran kemudian dianalisis menggunakan model sorpsi Halsey, Henderson, Caurie, Oswin, Chen-Clayton, GAB, dengan mengevaluasi akurasi melalui perhitungan nilai Mean Relative Deviation (MRD). Hasil penelitian menunjukkan bahwa model Oswin  y=0.0851x+0.0333 menghasilkan nilai MRD terendah yaitu 1,6497, sehingga model yang paling sesuai dalam memprediksi kadar air kesetimbangan bubuk pala. Dengan demikian, model Oswin dapat dijadikan acuan dalam merancang strategi pengeringan dan penyimpanan pala untuk menjaga mutu serta meningkatkan ekspor
