Abstract

The main componenet of lemongrass oil that is sitronellal and rhodinol (sitronellol and geraniol) was isolated by using vacuum of distillation fraksinasi. Variably the research included the variable continue to, that is the sample weight (300 mL) and process time (4 hours); and the variable changed, that is the pressure (80, 95 and 100 mbar) and the temperature (145, 150, and 160o C). Results of the analysis of the ras material showed that lemongrass oil that came from Kota Panjang, Gayo Lues, Province Aceh had the content sitronellal that was high that is of 51.067% and rhodinol of 30.761%. The characteristics from lemongrass oil was yellow faded, the ray index 1.466, the specific gravity 0.889 solubility in alcohol 1:1 clear and the round of optics 19.15. The distillation sitronellal, 28.87% rhodinol (22.60% geraniol and 6.27% sitronellol) and 11% other component. The condition for the process that was good enough in the isolation sitronellol used distillation vacuum of fraksinasi with the temperature and the pressure that were low that is 145o C and 80 mbar. The condition for the process that was quite good in the isolation rhodinol was use to use vacuum of distillation fraksinasi in the temperature and the pressure that were not too high and or low that is 150o C and 95 mbar.

Abstract

Research of energy efficiency for biodiesel production process by combining two orifices on  hydrodynamic cavitation reactor had been carried out. The aim of this reseach was to studied effect of the number of orifices toward increasing temperature without using external energy source to produce biodiesel that generated by cavitation effects on orifices. The results of preliminary research showed by combining two orifices arranged in series can produce the highest thermal energy reached 48oC. Result of biodiesel production showed that yield of the highest biodiesel was 96.34% using molar ratio a methanol:oil with comparison 6:1, KOH as catalyst (1%) for 50 minutes processing time. For biodiesel quality testing showed all selected parameter met the requirements of the Indonesian National Standard (SNI) 04-7182:2006. Identification of biodiesel compound using GCMS showed the biodiesel compounds consisted of methyl oleate, methyl palmitate, acid linoleid, methyl stearate, palmitic acid and oleic acid with the total contents 98.39%.

Abstract

Beluntas leaf (Pluchea indica L. Less) is one byproduct of the agriculture industry is knownas effective agents for efficacious as an appetite enhancer and aid digestion which is expected to spurgrowth. Since the old times, as plant Beluntas is considered have ability believed to reduce body odor,reduce heat and other benefits. Beluntas leaves can be used as a source of antioxidants, anti-stress, antibacterial,anti-cancer, lowering cholesterol, lowering fever, deodorizing fishy. This is due to Beluntascontaining amino acid (leucine, isoleucine, tryptophan, threonine), alkaloids, flavonoids, essential oils,chlorogenic acid, sodium, potassium, aluminum, calcium, magnesium, phosphorus, iron, vitamins A and C.This paper is a revision of some of the results of research that has been done on the potential and utilizationof industrial by products Beluntas leaves.

Abstract

Penelitian ini bertujuan untuk membuat mikrokapsul minyak jahe dengan menggunakan teknik spray drying. Bahan penyalut yang digunakan adalah maltodekstrin. Variabel penelitian yang dipelajari adalah konsentrasi maltodekstrin yaitu 10, 20 dan 30 (%-b/v) dan rasio minyak jahe terhadap maltodekstrin yaitu 1:8, 1:10, 1:12 dan 1:14 (b/v). Variabel penelitian dengan rendemen tertinggi akan digunakan untuk mempelajari pengaruh variasi suhu inlet proses spray drying (160, 170, 180 dan 190 oC). Hasil analisis gas kromatografi-spektrofotometri massa menunjukkan bahwa ada lima komponen terbesar yang terdapat dalam minyak jahe yaitu benzene (28,62%), zingiberene (19,46%), β-bisabolene (13,48%), cyclohexane (12,59%) dan farnesene (5,83%). Rendemen produk mikrokapsul minyak jahe tertinggi diperoleh pada perlakuan konsentrasi maltodekstrin 30% dan rasio minyak jahe terhadap maltodekstrin 1:14 yaitu sebesar 37 gram. Hasil penelitian juga menunjukkan bahwa peningkatan suhu inlet spray drying memberikan pengaruh terhadap kadar air, kadar minyak total, kadar minyak di permukaan dan kadar minyak terperangkap mikrokapsul minyak jahe. Hasil analisis Scanning Electron Microscopy menunjukkan mikrostruktur produk mikrokapsul minyak atsiri jahe yang dihasilkan memiliki bentuk yang bervariasi. ABSTRACTThis study aims to make ginger oil microcapsules using spray drying technique. Maltodextrine was used as a coating material. The process variables studied were maltodextrin concentration 10, 20 and 30 (%-w/v) and ratio of ginger oil to maltodextrin 1:8, 1:10, 1:12 and 1:14 (w/v). The best process variable with the highest product yield will be used to investigate the effect of inlet temperature variations of spray drying process (160, 170, 180 and 190 oC). The results of gas chromatography-mass spectroscopy analysis showed that the five largest components contained in ginger oil were benzene (28.62%), zingiberene (19.46%), β-bisabolene (13.48%), cyclohexane (12.59%) and farnesene (5.83%). The highest yield of ginger essential oil microcapsule products was obtained 37 grams at maltodextrin concentration 30% and ratio of ginger oil to maltodextrin 1:14. The experimental results showed that the inlet temperature of spray drying affected the moisture content, total oil content, surface oil content, and trapped oil content of the ginger oil microcapsules products. Meanwhile, Scanning Electron Microscopy analysis results showed that the microstructure of ginger essential oil products from several research treatments generally have various shape.
