Lotion is a cosmetic product with a lighter consistency than cream, consisting of a mixture of oil phase and water phase, with emulsifying ingredients, moisturizers, active substances, and fragrances. Its function is to hydrate the skin, reduce irritation, and protect from environmental influences. Chamomile extract and niacinamide provide additional benefits, such as anti-inflammatory characteristics and increased skin moisture. This study aims to evaluate the effectiveness of triethanolamine (TEA) as an emulsifier in lotion stability during storage, as well as the effect of stirring temperature on lotion quality. The research method used a 2 x 3 factorial design quantitatively. Of the 8 lotion formulas tested, only formula 3 met the standard requirements of organoleptically, pH, specific gravity and homogeneity tests. This formula has a TEA volume of 2 ml, mixing time for 25 minutes at 70℃, pH 8, foam texture, slightly yellow-green color, specific gravity 0.972, and homogeneity. This formula provides a moisturizing effect on the skin without side effects

This study aims to determine the effectiveness of avocado seed oil as a substitute for SLS which can be used to make environmentally friendly detergents. The method used in this research is mixing. The results obtained in this study are in the density test samples that meet the requirements are sample 1, sample 2, sample 5, and sample 6. In the viscosity test, high viscosity results were shown in sample 6. In the overall results of the pH test, the sample obtained a pH of 11 which did not meet SNI standards. If the pH of a detergent is more than 8-10 it will risk causing irritation to the skin and environmental pollution. In the saponin test, avocado seed extract contains saponin compounds because saponin compounds are known to form foam due to the combination of constituent compound structures. In the foam stability test, the foam produced must last around 60-70% of the initial volume and in the observation there are 4 samples that meet these requirements, namely sample 1, sample 3, sample 6, and sample 7 respectively 72%, 81%, 72%, and 81%. It can be concluded that sample 6 is better than the other samples

This study aims to determine the effect of moisture and drying rate on Kepok and milk banana species, on the production process of crispy banana. An electric oven was used to examine the drying process at variable temperatures of 70 ºC, 80 ºC and 100 ºC with slices of 1 mm, 2 mm, 3 mm and 4 mm thickness. The results showed that the lowest moisture content and maximum drying rate obtained in Kepok was at a temperature of 100ºC, namely 69.167% and 0.045 grams/minute respectively. Meanwhile, for milk banana, the lowest moisture and the maximum drying rate was obtained at a temperature of 100 ºC, namely 68.167% and 0.042 grams/minute respectively. Furthermore, the organoleptic test results showed that kepok and milk banana experienced browning at 100 ºC, but did not at 70 ºC and 80 ºC with a thickness of 1mm, 2mm and 3mm. In addition, the pore structure of both bananas expanded, while the structure of the bananas appeared bigger after drying.

Red beet pigments, betacyanin and betaxanthin, possess both health benefits and potential as natural colorants. This study investigated the efficacy of Microwave-Assisted Extraction (MAE) for their extraction from red beets. Pretreated beets were subjected to MAE employing varying microwave power levels (200, 400, and 600 W) and solvents (water, ethanol, and ethanol + citric acid). Betacyanin content varied from 23.77 to 59.28 mg/100g. Higher microwave power significantly increased betacyanin yield (p < 0.05), while the type of solvent did not exert a significant influence. Betaxanthin content was also affected by both microwave power and solvent polarity. Higher power settings and the more polar solvent mixture (ethanol + citric acid) resulted in greater extraction. These findings demonstrate the effectiveness of MAE for extracting both pigments from red beets, with optimal conditions dependent on the target compound of interest.

Every year the production of duck eggs in Indonesia has increased, this case leads to an increase in the waste of duck eggshells. Duck eggshell waste has components that can be utilized into a biosorbent. To improve the quality of the biosorbent, can be done with an activation method and immobilization method. The purpose of this study was to determine the effectiveness of biosorbents made from duck eggshell waste in absorbing Cd(II) metal. In this study, duck eggshells were activated with physical activation by heating in a furnace at a temperature of 900oC for 2 hours. Independent variables of this study are biosorbent mass, contact time and concentration of cadmium solution. Critical values for Cd levels optimization conditions are accomplished when the biosorbent mass 1.45 grams, contact time 100 minutes and Cd solution concentration 86 ppm with a percentage decrease in Cd levels in the amount of 89%.

Biodiesel is an alternative fuel which is generally produced from the transesterification process between vegetable oil and methanol, ethanol, or butanol with the help of a catalyst which aims to speed up the reaction. The raw material for making biodiesel, namely renewable vegetable oil, also sees Indonesia as a tropical country so that biodiesel can be produced on a large scale and is environmentally friendly. Vegetable oil can be classified into two, namely edible oil (food) and non edible oil (non-food). The research was conducted using non-edible vegetable oil, namely kemiri sunan oil, which was carried out using a two-stage transesterification method. This research was conducted to determine the optimization of the ratio of oil and methanol (1: 4; 1: 5; 1: 6), temperature (55⁰C, 60⁰C, 65⁰C) and reaction time (15 minutes, 30 minutes, 45 minutes) in making biodiesel from kemiri sunan oil, where the experimental results obtained the highest yield value of 82.79%. In the experiment, analysis of density, viscosity, moisture content and cetane number was also carried out. The results showed that the viscosity and cetane number obtained did not meet SNI for biodiesel.

Lemongrass oil (Cymbopogon citratus) is a plant that produces essential oils as a raw material for fragrance in cosmetics and perfumes. This study aims to determine the optimum conditions for the preparation of Lemongrass oil-wall emulsion (Tween 80 and Cethyl Alcohol) and to determine the effect of the independent variable in the form of the ratio of lemongrass oil-wall to the viscosity produced using the Response Surface Methodology (RSM). The novelty in this research is lemongrass oil with the addition of Tween 80 and Cethyl Alcohol as natural cosurfactants. Tests were carried out with three independent variables, namely stirring time (15, 20 and 25 minutes), stirring speed (20,000, 22,000 and 24,000 rpm) and lemongrass oil-wall ratio (1:3, 1:4, 1:5), which will be designed with the RSM method to obtain optimum operating conditions. Based on the results obtained, the optimal formula for lemongrass oil emulsion is on the 14th running result, which has a pH value of 6.4; density of 0.852; viscosity of 15,450 cP, type M/A, homogeneous and good stability without any change in colour, aroma, and texture. The influence of the lemongrass oil-wall ratio variable, namely the ratio variable, obtained a P-value of 0.000005, which means it is smaller than the value of α = 0.05 so that it can be said that the ratio has a significant effect on the viscosity of the emulsion.
