<em>Tea is a popular drink in the world. Types of tea which is rarely used is white tea. Besides consumed as a beverage, white tea can also be used in extracted form. White tea extract contains polyphenols compound, particularly catechins that can be used as an antibacterial. One of white tea extract uses that can be added to production of olive oil transparent soap based. This study aimed to determine the process of transparent soap production, looking for the best concentration of white tea extract, determine the characteristic and quality of transparent soap, and look for the extend of inhibition zone of Staphylococcus aureus in transparent soap. The treatments given in this research were the concentration of white tea extract 1% (w / v) with the addition of A (control soap) = 0% (w / w), B = 0,5% (w / w), C = 1,0% (w / w), and D = 1,5% (w / w) of 300 grams of soap bases. Transparent soap characteristics observed were physical-chemical properties, antibacterial and organoleptic test. The analysis showed that all transparent soap baths complied the SNI 06-3532-1994 requirements of solid soap, except the water content and evaporated substance and the amount of fatty acids. The best result of this research was soap with treatment B (with 0,5% (w/w) extract addition), which was chosen based on organoleptic test (such as aroma, hardness and foam quantity) and Indonesian National Standard (SNI) qualities of solid soap with best result in unsaponified fraction test, hardness, and foam stability.</em>

Physical And Chemical

The amount of mango production in Indonesia is quite high, but the quality of postharvest mangoes is still quite low. The quality of the fruit will decline due to contamination; one of the contaminants is fungi. The way to reduce the damage of postharvest products is by coating applications. The purpose of this study was to study the physical, chemical and antifungal activities of harumanis mangoes’s quality which had been given coating during storage that could cause postharvest losses of harumanis mangoes. There are 3 treatments, each of them are respectively the provision of corn based coating  6% tobacco extract, 8% tobacco extract and 10% tobacco extract. The physical and chemical properties of the antifungal coating of tobacco extract made from corn coating for post-harvest damage on harumanis mangoes were obtained by weight loss, texture, colour, respiration rate, vitamin C and total dissolved solid. Preventing coating can prevent damage after harvest and protect the harumanis mango; therefore the quality of the mangoes can be maintained. The best results from the priority with the largest diameter inhibition zone were given corn starch 10% tobacco extract. Then the higher the concentration of extract used, the greater the diameter of the inhibition zone obtained. Based on all the tests performed (physical, chemical, and antifungal) the best treatment from the treatment was obtained that consisted of mangoes with antifungal layers of corn starch 10% tobacco extract. Because the P3 obtained the best results in maintaining physical, chemical content and fungi for 15 days.

Kaffir lime has long been used by Indonesian people for hair care. The purpose of this research is to formulate anti-dandruff shampoo with active ingredients of kaffir lime extract, and physicochemical evaluation based on the Indonesian National Standard of shampoo products. The addition of ethyl acetate extract at concentrations of 20, 30, and 40% as the active ingredient of anti-dandruff shampoo formula. All shampoo formulas showed very strong anti-dandruff activity (inhibition zone 35.67 ± 0.58 mm), but still lower than the inhibition zone of chemical-commercial shampoo (p <0.05). The lime juice extraction shampoo formula is preferred by 34 panelists (p <0.05) in the hedonic test. The results also showed that all shampoo formulas met the pH and water content requirements according to the Indonesian National Standard. Further studies are needed to determine the stability and safety of shampoo preparations.

The Relationship

White tea is an unfermented tea made from young shoots of Camellia sinensis protected from sunlight to avoid polyphenol degradation. Although its levels of catechins are higher than those of green tea (derived from the same plant), there are no studies addressing the relationship between this tea and obesity associated with oxidative stress.The objective of this study was to evaluate the effect of white tea on obesity and its complications using a diet induced obesity model. Forty male C57BL/6 mice were fed a high-fat diet to induce obesity (Obese group) or the same diet supplemented with 0.5% white tea extract (Obese + WTE) for 8 weeks. Adipose tissue, serum lipid profile, and oxidative stress were studied. White tea supplementation was not able to reduce food intake, body weight, or visceral adiposity. Similarly, there were no changes in cholesterol rich lipoprotein profile between the groups. A reduction in blood triacylglycerols associated with increased cecal lipids was observed in the group fed the diet supplemented with white tea. White tea supplementation also reduced oxidative stress in liver and adipose tissue. In conclusion, white tea extract supplementation (0.5%) does not influence body weight or adiposity in obese mice. Its benefits are restricted to the reduction in oxidative stress associated with obesity and improvement of hypertriacylglycerolemia.

Sample Pair

The study aimed to describe the utilization of waste frying oils, originated mainly from households, in home-made soap production and to emphasize the advantages of soap biodegradation in comparison to biological treatment of oils. The physicochemical analyses of soaps were used to check the differences between the samples made of fresh and fried oils. Significant (p < 0.05) difference between the soaps made of fresh/fried olive oil pair was obtained, while the rapeseed sample pair did not differ significantly (p < 0.05). Malondialdehyde (MDA) exhibited notable differences with an increase from 1.94 μg/g to 2.33 μg/g for olive oil fresh/fried pair and from 3.43 μg/g to 4.10 μg/g for rapeseed–palm oil fresh/fried pair. The studies addressing the soap biodegradation process revealed that soaps are degrading up to four times faster than oils in waste processing plants. Literature data showed the syntrophic ways of soap degradation and degradation solely done by sulfate-reducing bacteria. Obtained results, same as literature data, indicated that soaps produced from fried plant oils represent acceptable products from the economic and environmental point of view. Soap production can be considered one of the possible ways toward reduction of waste oil disposal.

The Impact

Production of rice husk in Central Java province is around 2,825,000 tonnes annually. It can be used as an alternative energy source to substitute coal in combustion during cement production. This study was conducted to determine the impact of rice husk as a substitute energy source in cement production. The observations of rice husk comprised calorimetric tests, physical and chemical tests, and percentage rice husk substitution for coal as firing energy. The chemical properties of the cement tested include the chemical content, MgO and SO3 contents, loss on ignition, insoluble residue, and total alkali. The results show that the chemical content of cement which is produced using rice husk as a substitute for coal in the combustion process still meets the Indonesian National Standard.
