Abstract

The needs for colorant is increasing, so the colorant produced by natural substances begin to be substituted for synthetic colorant as technology and knowledge develop. The substitution can reduce production cost, but the synthetic colorants have negative effects. The synthetic colorants can be dangerous to our health and environment if they are used for food colorants and textile industry. Therefore, natural substances such as avocado seeds are still needed for coloring which is eco-friendly by applying science and technological development. This research aim to study the effect of extraction time and the ratio of solvent concentration to the concentration of anthocyanin extract and find good conditions in the anthocyanin color test process with the extraction time and the ratio of solvent concentration variable. This research has been carried out through 4 (four) stages: (i) extracting anthocyanin, (ii) separating the anthocyanin extract uses a solvent, (iii) coloring the fabric uses anthocyanin extract which is more concentrated, (iv) testing the anthocyanin colorant by washing it uses detergent. Dissolved anthocyanin concentration analysis is carried out with a UV-Visible Spectrophotometer. This method is applied for discovering the quantity of anthocyanins dissolved in the detergent solution after washing the cloth that has been colored. The research indicate that the largest anthocyanin extract is 0.10002 mL anthocyanin /mL solvent when the extraction time is 150 minutes and the ratio of solvent concentration is 1:13.

Abstract

Indonesia has various natural resources for traditional medication which have been used hereditary. One of them is Curcuma aeruginosa Roxb. It contains essential oil which has not been optimally utilized. Based on some researches, there are some types of essential oil which have been proved to gain both physical and emotional condition of somebody. The research of temu ireng essential oil is conducted by extracting the oil using volume and solvent variances. The solvents variance and its volume are ethanol (250 ml, 300 ml, 350 ml, 400 ml, dan 450 ml) dan n-hexane (250 ml, 300 ml, 350 ml, 400 ml, dan 450 ml). Subsequently, the extract oil is purified by using distillation apparatus in order to generated Curcuma aeruginosa Roxb essential oil. The analysis of absorbance in each cycle of volume variant and solvent is conducted in this research. Based on this research, it results several types of essential oil in accordance to its solvent and volume variances. By using ethanol as the solvent, it results 250 ml oil (91,433%), 300 ml (91,582%), 350 ml (91,731%), 400 ml (92,030%), and 450 ml (92,179%). Meanwhile, by using n-hexane as the solvent, it results 250 ml oil (91,113%), 300 ml (91,435%), 350 ml (92,081%), 400 ml (92,242%), and 450 ml (92,565%).

Abstract

Biji ketumbar (Coriandrum sativum L) merupakan tanaman bumbu-bumbuan yang sejak lama digunakan dan dimanfaatkan oleh manusia sebagai obat atau untuk meningkatkan cita rasa bahan pangan. Biji ketumbar, terkandung minyak atsiri sebanyak 0,8-1,8%. Minyak atsiri ketumbar memiliki banyak manfaat dan memiliki sejarah panjang akan kegunaannya sebagai obat tradisional. Ekstraksi biji ketumbar dapat dilakukan dengan proses ekstraksi dengan pelarut. Salah satu pelarut yang dapat digunakan ialah N-Heksana. Ketumbar terlebih dahulu dicuci untuk membuang kotoran yang terdapat pada permukaan kulit ketumbar. Lalu ketumbar dikeringkan kemudian dihaluskan. Lalu dilakukan ekstraksi dengan variasi suhu 45OC, 50OC, 55OC, 60OC, dan 63OC, kemudian variasi waktu yaitu 90, 120, 150 , 180, 210, dan 240 menit, dan variasi volume pelarut yaitu 150 ml, 200 ml, 250 ml, dan 300 ml, dengan berat biji ketumbar 70 gram dan dengan kecepatan pengadukan yang tetap yaitu 300 rpm. Setelah diekstraksi, hasil kemudian disaring kemudian didistilasi untuk mendapat minyak atsiri murni. Pada penelitian ini didapat bahwa kondisi operasi terbaik dicapai pada suhu 63O C dengan hasil minyak sebanyak 1,260 ml. Untuk waktu ekstraksi optimal terjadi pada waktu 150 menit dengan hasil minyak 1,561 ml. Kemudian untuk volume pelarut optimal yaitu pada 200 ml dengan hasil minyak sebanyak 1,561 ml.
