Abstract

Papaya leaves have long been known as leaves that contain meat tenderizers. Papaya leaves can soften the meat because it contains papain which is one of the protease enzymes. In the fresh papaya leaves there is sap which contains 5.3% papain. Meat tenderizer in powder form is more practical and more durable. One of the papain enzyme powder drying methods that is considered appropriate to be applied in the ginger powder production process is the foam mat drying method. This study aims to examine the foam drying process on papain enzyme activity using tween 80 (foam agent) and maltodextrin as filler to help maintain foam consistency. The drying process was carried out by varying the drying temperature (50oC, 55oC, 60oC, 65oC, and 75oC) and drying time (2 hours, 3 hours, 4 hours, 5 hours and 6 hours). The results of the analysis showed that the highest enzyme activity reached 408.7 U/mL for drying at an operating temperature of 60oC with a time of 2 hours..

Abstract

Sterno gel of hibiscus leaves (Hibiscus rosa-sinensis L.) is an alternative energy source that can be used as fuel because it has non-volatile characteristics, during the combustion process it does not smoke, does not have soot and does not produce harmful and carcinogenic gas emissions and does not have any harmful gases. the impact of emissions on the environment, Inside the hibiscus leaf contains saponins, -sitosterol, stigmasterol, taraxeryl acetate and 3-cyclopropane and their derivatives which will dissolve in both water and ethanol and will form colloids in water. With this composition, the researchers used hibiscus leaf biomass as fuel for sterno gel, where in this study the variables were filtrate mass of hibiscus leaf :10,1 20, 30, 40,50,60 and 70 grams and mass of carbopol :1, 1.5, 2 and 2.5 grams. From the research, it was found that the best burning time was 60 grams of hibiscus filtrate mass and 2.5 grams of carbopol mass, which was 25.02 minutes with the resulting gas emission values ​​of NOx: 4 ppm, SO2: 3 ppm and H2S: 2 ppm. While the calorific value is 3500 calories.

Abstract

Minyak jahe diketahui memiliki berbagai fungsi dan mempunyai nilai jual yang cukup tinggi. Permasalahan utama yang dihadapi industri minyak jahe di Indonesia adalah bahwa minyak jahe dari Indonesia tidak dapat memenuhi persyaratan karakteristik mutu yang ditentukan pada standar internasional yakni putar optik yang bernilai negatif akibat dari rendahnya kadar zingiberene minyak jahe. Kecilnya komposisi zingiberene pada minyak jahe Indonesia dikarenakan pada proses destilasi konvensional, zingiberene mengalami degradasi thermal. Alternatif proses produksi minyak jahe yang ditawarkan adalah proses produksi minyak jahe menggunakan teknologi Microwave Assisted Extraction (MAE). Penelitian ini bertujuan menentukan kondisi optimum proses ekstraksi minyak jahe menggunakan teknologi MAE. Variabel pada penelitian ini meliputi daya dan perlakuan bahan. Hasil penelitian menunjukkan bahwa hasil terbaik diperoleh pada ekstraksi daya 300 Watt yaitu rendemen 2,01 % dan kadar Zingiberene 6,72 % sesuai dengan SNI 06-1312-1998. Minyak jahe hasil ekstraksi menggunakan proses MAE memiliki kadar Zingiberene yang lebih besar dari kadar Zingiberene yang dihasilkan dari proses ekstraksi dengan pemanasan konvesional.

Abstract

Essential oils are often also referred to as Essential Oils, Etherical Oils, or Volatile Oils, which are compounds that are volatile and insoluble in water and have natural extracts from plants derived from leaves, flowers, wood, seeds, roots, as well as fruit skin. Lemon oil is an essential oil that is obtained from the distillation of lemon peel and is used as an aromatherapy oil to cure several disorders such as headaches and nausea. The main content of lemon peel oil is limonene, which is about 94%, besides that there are other compounds such as terpenes, sesquiterpenes, aldehydes (about 3.4-3.6 n-citronella citral) and esters (about 1% geranyl acetate). Steam distillation is a separation process to produce lemon peel oil which is separated by distillation, the steam is obtained by distillation which is carried out at 96 oC, for 1.5-2 hours. The variables used were pretreatment temperature: 30 oC, 45 oC, 60 oC, 75 oC, 90 oC and pretreatment time: 1.5 hours, 2 hours, 2.5 hours, and the best results obtained for lemon peel oil were for material treatment at 1.5 hours. with a temperature of 45oC with Limonene content of 36.714%, α-Pinene 2.678%, and yield 0.0659%.

Abstract

Indian pluchea leaf is one of the medicinal plants included in the essential oil group that is not traded in Indonesia, even though it has flavonoid levels that are useful, especially in the health industry. For this reason, research related to the process of extracting beluntas essential oil is still limited. The use of microwaves is considered to extract essential oil better and faster. This study aims to compare modern extraction methods, namely MAE (Microwave-Assisted Extraction) and MAHD (Microwave Assisted Hydro-Distillation) using different solvents. Other variables used in this study were drying method and microwave power. The results showed that the best results in the use of MAHD method with oven drying type and Microwave power of 300 watts which produced flavonoid content of 3.64%

Abstract

Essential oil, also known as etheric oil (Aetheric Oil), is a volatile compound widely utilized in various industries, including pharmaceuticals, cosmetics, and aromatherapy. In this study, the main material used is orange peel (Citrus aurantium), which is extracted into essential oil using the Microwave-Assisted Extraction (MAE) method. The study aims to obtain a high essential oil yield with optimal quality. The variations in microwave power used include 100 W, 150 W, 200 W, 280 W, and 399 W, with soaking durations of 3, 4, and 5 days. Various parameters were analyzed to assess the quality of the obtained essential oil, including organoleptic tests (color), yield, refractive index, density measurement, and analysis using Gas Chromatography-Mass Spectrometry (GC-MS). The results indicate that the optimal condition was achieved at a microwave power of 280 W with a soaking duration of 5 days. Under these conditions, the essential oil yield was relatively high, with a refractive index of 1.040 and a density of 1.039. The obtained essential oil had a dark yellow color, indicating good quality. GC-MS analysis revealed that limonene, the main component of orange essential oil, was detected at 1.30% at a retention time of 3.675 minutes, followed by 1.80% at a retention time of 4.240 minutes, and 0.28% at a retention time of 12.750 minutes. Based on these findings, the MAE method proved effective in extracting essential oil from orange peel, particularly under optimal power and soaking conditions. This study provides further insights into efficient extraction techniques for producing high-quality essential oils.
