The techno economic modeling of dried black potato (Plectranthus rotundifolius) was studied by employing electrical cabinet oven. The parameters investigated were including parameter obtained from analysis of capital budgeting, breakeven point and financial ratio of rentability. The obtained payback period was 2 years 11 months by investing 53.000.000 rupiah for machinery and 10.000.000 rupiah for start-up cost as initial capital. By assuming 10 years of dried black potato production, the value of net present value was equal to 1.207.982.611 rupiah. The value of gross profit margin and net profit margin were 0.97 and 0.87, respectively. Regarding to the positive value of net present value, the lower payback period value, and the high value of internal rate of return (74.47%) and also the profitability index (20.17), the modeling of techno economic was positively recommending the commercial application of dried black potato by using electrical cabinet oven.

Homogenization is the process of homogenizing particle size in an effort to maintain the stability of a mixture formed from 2 phases that cannot be fused or commonly called emulsions. This study aims to analyze the effect of homogenization speed and differences in solid concentration in homogenization process using homogenizer. The ingredients used are Virgin Coconut Oil as a solute, Aquadest as a solvent, and soy lecithin as an emulsifier. Several stages of analysis are density, viscosity, microscopic, and emulsion stability analysis. The results obtained from this study were optimum stirring speed of 22,000 rpm with optimum homogenization time of 4 minutes, solid concentration of 60% obtaining density of 0.78 gr/mL, viscosity of 5.86 cP, stability of 100%, and most stable microscope test. The results showed that the greater the stirring speed and time, the smaller the density and viscosity value produced and the greater the stability value obtained. The greater the concentration of solids, the greater the density, viscosity, and stability of the emulsion.

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.

Abstract - 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.

The establishment of subcritical fluid application for zingiberene extraction was studied by employing water as a green solvent. The zingiberene content was observed by using Liquid Chromatography-Mass Spectrofotometry and regarding to the independent variable of temperature, extraction time, ginger-solvent ratio and aging time. By applying subcritical water, the critical value of zingiberene content obtained was 0.036%. This value was approached by the surface modeling of alpha for rotatability design which performed at 125  C, 20 min of extraction time, 0.08 of ginger to solvent ratio and 9 min of aging time of extraction parameters. The surface modeling was validated by plotting the observed and predicted value of zingiberene content and evidenced by the value of R-square at 0.76.

The production of bath soap based on natural ingredients is still rarely found in the market. Many in circulation still use synthetic materials as active ingredients. In this soap-making formulation using natural antioxidants in the form of white tea extract, anti-oxidants from plant extracts are usually added as additives (1-8% of the final soap composition). The research method used is a response surface methodology with a Central Composite Design (CCD) design. The resulting liquid soap product will be analyzed including physicochemical tests and organoleptic tests. Soap with the most appropriate quality according to SNI fell on the 4th variable, with the addition of KOH of 67 grams and a reaction time of 35 minutes. Variable soap 4 has a pH of 10, a free alkali content of 0.0541%, and an unsaponifiable fat content of 0.37%.

Homogenization is the process of uniform particle size in an effort to maintain the stability of a mixture which is formed from 2 incompatible phases or so-called emulsion.Emulsion is a complex system consisting of a liquid phase which is spread over another immiscible liquid phase which is usually through mechanical shear. All emulsions are thermodynamically unstable due to contact between oil and water molecules. However, emulsions can be stabilized rapidly in the presence of emulsifying or thickening agents such as Tween 20 and Tween 80. Apart from the addition of emulsion stabilizing surfactants, the speed of stirring also has an effect in stabilizing the emulsion. This research was conducted to determine the effect of stirring speed and addition of surfactants Tween 20 and Tween 80 on the stability of soybean oil emulsion. The results of density, viscosity, stability, and microscopic tests showed that the emulsion was treated with the addition of tween 80 with a stirring speed of 30.
