ANALISIS SENYAWA 6-GINGEROL TERHADAP RIMPANG JAHE YANG DIEKSTRAKSI DENGAN METODE LIQUID CHROMATOGRAPHY MASSA SPECTROMETRY (LC-MS)

Data BPS 2017, menunjukan bahwa jahe adalah tanaman biofarmaka kelompok rimpang yang mempunyai luas panen paling tinggi, yaitu sebesar 30 ton per tahun dengan kondisi produksi yang relatif stabil. Ekstraksi pada rimpang jahe adalah penyarian zat-zat aktif dari bagian tanaman obat yang bertujuan untuk menarik komponen kimia yang terdapat dalam simplisia yang didasarkan pada perpindahan massa komponen zat padat ke dalam pelarut. Tujuan dari penelitian ini adalah menganalisis pengaruh proses pengeringan terhadap aktivitas senyawa 6-gingerol pada ekstrak jahe dengan metode ekstraksi maserasi menggunakan pelarut etanol berkonsentrasi 30%, 70%, dan 96%. Hasil dari analisa kadar 6-gingerol dengan menggunakan LC-MS didapatkan bahwa kandungan tertinggi terdapat pada sampel yang diekstraksi dengan etanol 96%, yaitu 2,01%. Sedangkan, kadar terendah terdapat pada etanol 30%, yaitu 0,64%. Di lain sisi, sampel jahe yang diekstraksi dengan etanol 70% memiliki kandungan 6-gingerol sebesar 1,21%. Hal ini disebabkan oleh semakin pekatnya konsentrasi suatu pelarut, maka akan mengakibatkan semakin tingginya konstanta dielektriknya.

PENINGKATAN PENGETAHUAN PETANI TERHADAP PERBENIHAN TANAMAN DURIAN

Carotenoids in red palm olein oil (RPOOO) have been scientifically proven to have good functional properties for the human health so that RPOOO has the potential to be used as one of the healthy drinks. One of the problems faced in the use of RPOO as a health drink is the taste and aroma is less interesting. This study aims to: 1) To obtain the ratio of ratio between RPOO and salak sidempuan extract used to obtain stable emulsion, acceptable viscosity, and acceptable RPOO with salak Sidempuan emulsion product Emulsions were prepared using 2% carbonmethylcellulosa as emulcifier and four different composition ratios of RPOO and salak extract were prepared. Emulsions characteristics and their sensory acceptability were investigated. The results of this study showed that the ratio of RPOO ratio and 1: 2 salak extract obtained the best stability with viscosity of 175 cP emulsion. In addition, emulsions with an RPOO ratio and 1:25 salak extract yield acceptable levels sensory attributes such as color, aroma and taste.

Carotenoids in red palm olein oil (RPOOO) have been scientifically proven to have good functional properties for the human health so that RPOOO has the potential to be used as one of the healthy drinks. One of the problems faced in the use of RPOO as a health drink is the taste and aroma is less interesting. This study aims to obtain the ratio of RPOO and salak sidempuan extract used to obtain stable emulsion, acceptable viscosity, and acceptable emulsion product. Four emulsions were prepared using 1% carbonmethylcellulosa as emulcifier and four different composition ratios of RPOO and salak extract were prepared. Emulsions characteristics and their sensory acceptability were investigated. The results of this study showed that the ratio of RPOO ratio and 1: 2 salak extract obtained the best stability with viscosity of 175 cP emulsion. In addition, emulsions with an RPOO ratio and 1:25 salak extract yield preferable levels of sensory attributes such as color, aroma and taste.

PENGARUH FERMENTASI ALAMI LIMBAH INDUSTRI KALAMANSI TERHADAP PENINGKATAN RENDEMEN DAN MUTU MINYAK ATSIRI

Orange peel oil is stored in the oil glands located on the outer skin. Orange peel contains cellulose, hemicellulose, pectin and other components. Microorganisms can damage the skin layer and are expected to increase oil yield. This study aimed to evaluate the effect of natural fermentation on citrus peel waste on yield and quality of the essential oils produced. This study used natural fermentation time as a treatment factor for 2, 3, and 4 days. The results of this study indicated that the natural fermentation time that occurs in kalamansi peel waste can increase the oil yield. Natural fermentation for 4 days produces the highest yield. This natural fermentation process also does not affect the quality characteristics of the oil.

KARAKTERISTIK MUTU BAKSO BELUT (Monopterus albus) DENGAN VARIASI SUBSTITUSI TEMPE

Meatballs are a type of processed food made from chopped fresh meat, fillers, binders and spices. Besides beef, meatballs can also be made from eel meat because eel meat has a high enough protein. Tempe can be used as a substitute for eel meat because the price of tempe is more affordable and the protein content is also quite high. The purpose of this study was to analyze the effect of the composition of eel and tempe on the protein and organoleptic content of eel meatballs. The results of the analysis showed that the more use of tempe composition, the meatball protein content increased by 19.27%. The results of organoleptic analysis of the color, taste, aroma and texture of meatballs with the treatment of eel and tempe composition showed significant differences. The more the use of tempe composition the assessment of color, taste, flavour and texture is decrease. The results of the average color oranoleptic are between 3,75 (likes) to 4,25 (likes), the average organoleptic taste is between 3,65 (likes) to 4,05 (likes), the average organoleptic flavour is between 3,35 (rather likes) to 4,30 (likes) and organoleptic texture averages between 3,65 (likes) to 4,20 (likes).

PENGARUH VARIASI WAKTU PERENDAMAN SAMPEL DAN JUMLAH PELARUT HOMOGENASI TERHADAP PERSENTASE EKTRAK PROTEIN DAUN KELOR (Moringa oleifera)

This research is one form of utilization of food plants, namely Moringa (Moringa oleifera). M. oleifera can grow well in Bengkulu Province. The leaves of M. oleifera contain protein compounds that behave like lectins. This compound can be used as an antimicrobial material. The stages in this study include the extraction of M. oleifera leaf protein using salting in and salting out methods. This study aims to determine the effect of the immersion time and the amount of solvent in the homogenation stage extraction process on the percentage of protein extract. The results showed that the immersion time had a significant effect compared to the amount of solvent in the homogenation stage of Moringa oleifera leaf protein extraction. The longer the time needed, the greater the percentage of M. oleifera leaf protein extract. This research is useful for researchers, the public, the health sector, and the development of science and education. Keywords: Moringa oleifera, Extraction, Protein
