Sifat Antimikroba dan Pengaruh Perlakuan Bahan Baku terhadap Rendemen Minyak Sereh Wangi (Antimicrobial Properties and Effects of Raw Material Treatments on Citronella Oil Yield)

Citronella oil is one of the non-timber forest products (NTFP) and commercially obtained from the distillation of the leaves of the Cymbopogon nardus L. This study aims to determine the effect of the size of the distillation raw material and storage time of the raw material on yield and determine the antimicrobial properties of citronella oil from plants in the production forest Register 40 KPH Gedong Wani, Lampung Selatan Regency. The research was conducted using a complete randomized block design (RAKL) with two factors, namely the size of the distillation raw material (whole leaf, 5 cm, 10 cm, and 15 cm) and the storage time of the raw material (fresh, 2 days, and 4 days) which was carried out in 3 replications. The variables measured were yield, specific gravity, and solubility of citronella oil in alcohol. The inhibition ability test of citronella oil against bacteria using essential oil obtained from distillation at the highest yield conditions, namely fresh leaves and leaf size of 5 cm using the diffusion well method. The results showed that the storage time factor, the size of the distillation raw material, and the interaction between the storage time and the size of the raw material had a significant effect on the yield of citronella oil. The highest yield of citronella oil was achieved in the condition of fresh leaves with a size of 5 cm, namely 2,09%. Density and solubility in alcohol of citronella oil produced met SNI 06-3953-1995 standard, respectively 0,8718-0,8928 g/ ml and 1:2. Citronella oil has strong antibacterial properties against Propioni acne, Escherichia coli, Staphylococcus aureus, and Bacillus cereus with inhibition zone diameters were 40,20 mm, 18,36 mm, 13,07 mm, and 18,80 mm, respectively. Citronella oil from plants in Register 40 KPH Gedong Wani has potential as a raw material for the cosmetic and disinfectant industry. Keywords: antimicrobial, citronella oil, yiel

Survey and study on yield and quality of patchouli oil in Aceh Barat Daya District, Indonesia based on original area of raw materials, methods and length of distilation

Patchouli oil from patchouli plant (Pogostemon cablin Benth) is one of important essential oils as a source of Indonesian foreign exchange.  It is about 90% of world patchouli oil from Indonesia (Suara Merdeka, 2006). The objectives of this research were to assess the yield and quality of patchouli oils from four different villages in the sub district of Kuala Batee, Aceh Barat Daya based on the original area of raw material and the method of distillation, also based on length of distillation. The nested design was used in this research with the treatment of two factors combination, with the level of one factor similar but not identical. The treatments were the original area of raw material and the distillation method used in the original area of the raw material (BM1-4), and the length of distillation (5, 6, and 7 hours). Parameter observed were yield, specific gravity, refractive index, alcohol solubility, the concentration of patchouli alcohol, ester number, acid number, and the sensory test on color and clarity.  The results indicated that the original area of raw material and distillation method (BM) had a significant effect on yield, refractive index, clarity, and acid number. The yield was 2.85%-4.5%, and patchouli oil from BM4 and BM2 gave higher yield but lower patchouli alcohol concentration, and clarity. The results also indicated that the longer time of distillation the higher patchouli oil yield, specific gravity, and patchouli alcohol concentration. However, it affected the lower alcohol solubility and clarity, the higher ester number, and the darker color of the patchouli oil. The concentration of patchouli alcohol in this study ranges from 21.36% to 34.03%. Patchouli oil yielded in this research have complied the SNI 06-2385-200

Pengembangan Minyak Nilam Sebagai Aromaterapi Dan Potensinya Sebagai Produk Obat

Abstrak. Aromaterapi adalah suatu bentuk terapi atau pengobatan menggunakan bahan tanaman volatil, yang bertujuan untuk mengatur fungsi kognitif, mood, dan kesehatan. Tanaman volatil dikenal juga minyak atsiri. Minyak atsiri biasa diperoleh dari tanaman dengan berbagai cara yang berbeda-beda seperti ekstraksi, penyulingan dan distilasi fraksinasi.  Salah satu minyak atsiri adalah minyak nilam. Kandungan minyak nilam yang utama yaitu patchouli alcohol (40-50%) digunakan sebagai bahan baku, bahan pencampur dan fixative (pengikat wangi-wangian) dalam industri parfum, kosmetik, dan obat-obatan. Pengembangan minyak atsiri sebagai aromaterapi perlu dilakukan sebagai upaya peningkatan pemanfaatan dari produk minyak atsiri. Komponen aroma dari minyak atsiri cepat berinteraksi saat dihirup. Penelitian ini dilakukan untuk mengukur aktifitas lokomotor pada mencit untuk melihat efek yang ditimbulkan setelah di inhalasi dengan minyak nilam. Hasil menunjukkan adanya penurunan aktifitas setelah diinhalasi dengan minyak nilam. Ini menunjukkan minyak nilam memberikan efek depresi sistem syaraf pusat terhadap mencit. Persentase penurunan aktifitas gerak terbesar pada dosis 0,5 ml.Development of Patchouli Oil as Aromatherapy and Its Potential as Medicinal ProductsAbstract. Aromatherapy is a form of therapy or treatment using material from a volatile plant, intended to regulate cognitive, mood, and health function. Volati is also known for essential oil. Essential oil is often obtained from plants in various ways such as extraction, distillation and distillation of fractures. One essential oil is patchouli oil. The primary patchouli oil content is alcohol (40-50%), which is used as a ingredient, mixative and fixative in the perfume, cosmetics, and drugs industry. Commercial loans grew by 14 percent to RPM from the same period last year. Essential oil scent components must interact quickly when inhaled. The study was done to measure the locomotive activities of er er er to see the effect that was caused after inhalation with patouli oil. Results indicate a decrease in activity following inhalation with sapphire oil. This suggests patchouli oil, giving a depressed effect of the central nervous system on chiming. It's the largest drop in activity at a 0.5 ml dose

Beetroot is one of the tubers that grows in Indonesia and is high in antioxidants and carbohydrate content. Beetroot bulbs contain betalain pigments which are a combination of betasianin purple pigments and betasianin yellow pigments which function as natural dyes. Usually beetroot is consumed by juicing or processed again into fine texture food, but it is necessary to diversify beetroot products into attractive and popular products for consumption by the majority of Indonesians, for example rolled cookies. To increase the nutritional value of rolled cookies, other ingredients can be added such as green bean flour. This study aims to study the process of making rolled cookies from beets and also to determine the effect of adding green bean flour and the comparison of the number of beet paste and mung bean flour to the level of preference and acceptance of the resulting rolled cookies. The research design used was a Completely Randomized Design (CRD) with 2 factors studied. The first factor is the ratio of wheat flour and red beetroot paste consisting of 3 levels, namely R1 = 30: 70, R2 = 50: 50, R3 = 70: 30. The second factor is the percentage of green bean flour which consists of 3 levels, namely K1 = 50%, K2 = 40%, K3 = 30%. Each treatment was repeated 2 times to obtain 18 trial units. Observations made consisted of hedonic tests and acceptance levels. From the results of the study it can be stated that the treatment has a very significant effect (P10.01) on the hedonic test which includes (color, aroma, taste and texture), and is very significant (P≥0.01) on the level of acceptance which includes (color, aroma, taste, hedonic quality taste, texture, hedonic texture and overall quality). The best formulation of rolled cookies based on organoleptic parameters is obtained in the K2R2 combination. The best rolled cookies have a preference for color of 3.71 (likes), aroma of 4.48 (likes), flavor of 4.43 (likes) and flavor of 4.56 (likes), while the level of acceptance of rolled cookies is 4.53 ( likes), aroma 4.53 (likes), taste 4.56 (likes), hedonic quality taste 4.50 (likes), texture 4.50 (likes), hedonic quality texture 4.56 (likes) and overall acceptance 4 , 23 (likes)
