The best asphaltene dissolver produced was MESA 1% in toluene with the lowest interfacial tension value of 3. 95E-03 dyne/cm and solubility degree of 69. 58%. Cleaner production is a technique to reduce environmental pollution and also reducing resources consumption. The aim of this research was to choose alternate solutions for typically the implementation of cleanser production in published batik in Batik Puspa Kencana Compact Medium Enterprise applying Analytic Hierarchy Method method. Identification regarding the problem applied Ergonomic Checklist regarding Cleaner Production, which often consisted of vitality usage in basic, water usage on general, material in addition to chemical substance use generally speaking, and likewise prevention of polluting of the environment and waste on general.
Asphaltene deposition is the major problem inside petroleum industry leading to slow production and even operational shutdown with regard to removal of debris. This research has been conducted to acquire the best formulation of asphaltene dissolver to dissolve asphaltene deposits with the use of an palm oil anionic surfactant and to obtain performance information of asphaltene dissolver formula. The tested formulation were methyl ester sulfonate acid and methyl ester sulfonate, each with concentrations of 0%, 1%, 3%, and 5% in toluene mixed at a heat of 40°C for 30 minutes.
While the associated with RMSE, MAE, MRE ofthe process associated with the model screening was 0. 226% wb, 0. 129 % wb, plus 1 . 496% respectively. Growing population make public consumtion in term of foods becoming more complex, resulting in the opportunities to produce new product. One of them is producing new product from vegetables, which is now widely grown variety of organic vegetables.

The result shows that “Just buying dyes are always used” was the best alternative solution to implement cleaner production that can be implemented by the company. Cleaner production can be done by buying raw materials as needed and at the right time. Synthesis of foaming agent was conducted by reacting fatty acid of vegetable oil and alkaline. In this study, the selected fatty acid consisted of palm oil as raw substance; with NaOH in addition to KOH as alloisomer materials.
The particular support material may have a crucial effect on the particular stability from the enzyme and the effectiveness of enzyme immobilization. Rennet contains numerous enzymes, including the proteolytic enzyme that will coagulates the dairy, causing it in order to separate into shades and liquid. The particular active enzyme within rennet is known as chymosin or rennin yet there are furthermore other important digestive enzymes inside it, e. h., pepsin and lipase. Lactase is applied commercially to organize lactose-zero products, particularly whole milk, for such persons. It is likewise employed in preparation regarding ice cream, to produce a creamier and sweeter-tasting product. Like just about all catalysts, enzymes job by lowering typically the activation energy to get a reaction, thus considerably accelerating the level in the reaction. Ethanol production from wheat or grain straw hemicellulose hydrolysate by Pichia stipitis.
