Red ginger is a spice plant that has high economic and social value. One of the uses of red ginger is to process it into a product, namely essential oil. This study aims to determine the optimization of the extraction process conditions on solvent volume, time, and extraction power that can produce optimum yield and residual content of red ginger essential oil solvent. The extraction was carried out with the help of microwaves. The research method is experimental design and optimization process with Response Surface Methodology (RSM) type Box-Behnken Design (BBD). The results showed that the optimum yield was at 700 mL solvent volume, 1 min extraction time, and 10% power (69.9 watts) with the equation Y = 0.2076 + 0.0262A – 0.0300B – 0.0013C and the concentration conditions the optimum remaining solvent with the equation Y = 4.98 – 1.0000A + 4.56B + 5.44C. The optimal yield of red ginger essential oil was 0.205%, with a residual solvent content of 3.8%, specific gravity 0.885, acid number 1.399, refractive index 1.485. The results of the optimum residual solvent content of -6.023%. Based on the results obtained, the yield value with the help of microwaves is higher than that without the help of microwaves. Keywords: Essential oil, Microwave, Residual solvent content, Response surface methodology (RSM), Yield.

Face mist preparations are liquid preparations that are sprayed on the face. A natural ingredient that can be added to the anti-acne face mist preparation is butterfly pea (Clitoria ternatea L.) because it contains flavonoid which has the potential as antibacterial. This study aimed to determine the best concentration of butterfly pea extract in an anti-acne face mist preparation. The research method used was laboratory experimental with data analysis using ANOVA, Duncan's test, and descriptive analysis. This study consisted of 4 treatments with varying concentrations of butterfly pea extract namely: treatment A (0%%) treatment B (2%), treatment C (4%) and treatment D (6%). The results showed that all treatments met the quality parameters of appearance, viscosity, spray conditions, inherent resistance properties, and drying time. It did not irritate as well. The best concentration of butterfly pea extract in an anti-acne face mist preparation was 4% because it complied with the requirements for appearance, viscosity, spray conditions, inherent resistance properties, no irritation, stability for 28 days of storage, and had the highest antibacterial activity.

Pepper is one of the agricultural commodities that Indonesia widely exports. Pepper can be processed into various products, including essential oils. Pepper essential oil can be extracted using several methods, including the microwave. This method can speed up the essential oil extraction process. Optimization was carried out using the Box-Behnken design using the three independent parameters: solution ratio, time, and microwave power. The upper and lower limits used for the independent variables are solvent amount of 1,350 mL and 750 mL, time of 90 minutes and 60 minutes, and microwave power of 440 watts and 136 watts. The optimal data generated is treatment with a solvent amount of 1,050 mL, 90 minutes, and 440 watts of power, resulting in validation data of 99.046%. The optimal essential oil treatment gives a specific gravity of 0.8281, a refractive index of 1.4824, solubility in ethanol 1:2, acid number 0.739 mg KOH/g, ester number 19.599 mg KOH/g, and a hue value of 186,38 (green). Oil with optimum treatment also has an IC50 antioxidant activity of 32,919.9 ppm. Keywords: Antioxidant; Extraction; Microwave; Pepper; RSM.

Lemon contains essential oil compounds found in the peel, namely the flavedo. This section can produce essential oils by various methods, including the distillation method. Differences in distillation methods can affect the quality of essential oils. In the essential oil production process, paying attention to the distillation method and the samples of raw materials used is necessary. This study compares the process of extracting lemon peel oil using hydrodistillation and hydro-steam distillation methods.This research has enormous benefits for obtaining the best essential oils using a method that has stable quality and at a not too high cost. The process conditions are carried out by applying the influence factors of temperature, distillation time, and the ratio of raw materials to yield and aroma characteristics. The heating temperature is 100 oC, the distillation time is 4 hours, the raw material ratio is 1:5, as well as the pretreatment process of raw materials. The resulting steam is condensed, and the distillate, a mixture of oil and water, is separated using a separatory funnel. The oil is purified with anhydrous sodium sulfate (Na2SO4) to separate the oil from the remaining water. The best results were obtained from the research results in the hydrodistillation method with a heating temperature of 100 oC, a distillation time of 4 hours, and a raw material size of 1 cm with a % yield of 0.99%. As well as, the aroma produced is not too strong to get a value of 1 for the hydrodistillation method, and the aroma characteristics are quite strong with a scale of 3 produced by the hydro-steam distillation method. As well as the % yield value generated is 0.495%.

Corn is one of the abundant agricultural commodities in Indonesia. This abundant production of corn leaves considerable waste. One of the wastes produced is corn pericarps. Corn pericarps contain lignocellulose, whose utilization has not been studied much. This study aims to determine changes in the lignocellulosic content of corn pericarps in the physico-chemical delignification pre-treatment using electromagnetic waves with microwaves with various solvents NaOH 4% and distilled water. The lignocellulose content was tested using the Van Soest method. The results showed that the raw material for corn pericarps contained 50.4% hemicellulose, 14.6% cellulose, and 0.98% lignin. The results of pre-treatment using a microwave with NaOH 4% solvent produced 14.6% hemicellulose, 33.98% cellulose, and 0.6% lignin, and distilled water yielded as much as 50% hemicellulose, 15.58% cellulose, and 0.8% lignin. The pre-treatment method using microwave can reduce lignin levels by up to 38.78% with NaOH solvent and 18.37% with distilled water. In addition, this pretreatment method can also degrade hemicellulose as much as 71.03% with NaOH solvent and 0.8% with aquadest solvent. Thus, the use of NaOH as a solvent showed a much better ability to delignify and degrade hemicellulose than distilled water.
