Abstract

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.

Abstract

One of dried tea product competitiveness can be seen from the quality of the tea. Therefore, to produce good quality tea is necessary to reduce the damage to dry tea. The implementation of Good Agricultural Practices (GAP) during the process of picking fresh tea leaves and Good Manufacturing Practices (GMP) during processing to produce dry tea is a way to obtain quality tea. This study aims to analyze the causes of damage to the tea during the production process and to find a preventive solution. A case study conducted on KSU XXX, Sukatani Village, District Cilawu, Garut regency producing Iroet tea. The research method used is a case study and used qualitative design. Some of the causes of damage occurring in the Iroet tea production process are the farmers' bad habits while picking tea shoots, carelessness of factory workers when sorting, and the production process activities are undertaken by the workers are inconsistent with GAP and GMP. Based on the three causes, the main cause of damage to Iroet tea products are workers who do not apply GAP and GMP during the production process, resulting in poor quality of the resulting tea. The solution to prevent the destruction of iroet tea products is to add one to three grading workers, and pay farmers shoots in accordance with the grading results.

Abstract

Vegetative stage is an essential element for plants that shoot harvested. At that stage, the growth regulator application can directly increase the production quantively accelerate the potential formation and growth of roots and shoots. Coconut water is one of a  natural sources of growth hormone that has a potency to increase the early growth of the tea plant. This experiment aimed to find out the response of tea plant growth on the lowlands after centering with coconut water application. This experiment was conducted in experimental garden of Faculty of Agriculture Unpad, Jatinangor, Sumedang at an altitude of 750 m above sea level and Inceptisol terrestrial soil. The experiment began in February 2016 until June 2016 using Split Plot Design, consisting of two factors and three replications. The main plot is a type of clone (K) which consists of two levels, namely: k1 = GMB 7, k2 = GMB 11. Sub plot is a coconut water concentration (A) consisting of five levels: a0 = coconut water application (control), a1 = coconut water concentration 25%, a2 = coconut water concentration 50%, a3 = coconut water 75% concentration, a4 = coconut water 100% concentration. The experimental results showed that coconut water had a significant effect on all treatments. The interaction of plant height variable at 14 WAC - 16 WAC (Week After Centering), canopy width at 12 WAC - 16 WAC and stem diameter at 14 WAC - 16 WAC and no significant effect on plant height at 2 WAC - 12 WAC, canopy width at 2 WAC - 10 WAC, and stem diameter at 2 WAC - 12 WAC, at 2 WAC - 12 WAC. In general, GMB 11 clone tea plant that applied 75% coconut water performed the best growth response on tea growth in the lowlands after centering.

Abstract

White tea is produced from tea shoots with simplest processing. This unfermented tea contents a lot of chemical constituents such as polyphenol that present potent antioxidant capacity. In this research, we analyzed total phenolic content and antioxidant capacity of white tea ethanol extract after exposing simplicial with gamma rays doses of 0; 2.5; 5.0; 7.5; 10.0; and 12.5 kGy. Gamma ray irradiation in pharmaceutical can be used as one of the most efficient method to reduce microorganisms. The extraction of simplicia used Microwave-assisted extraction (MAE) with ethanol 60% as the extraction solvent. The determination result of total phenolic levels of white tea extract irradiated at a doses of  0; 2.5; 5.0; 7.5; 10.0; and 12.5 kGy were 121.62; 148.73; 187.28; 161.88; and 162.28 mg GAE/g. The antioxidant capacity value was 16.67; 19.63; 30.08; 25.60; 23.11; 16.15 %. The total phenolic content and antioxidant capacity showed the highest irradiation at 5 kGy dose.

Abstract

The instability of tea shoots supply from the plantation to the factory was often a problem. In the flush season where tea shoots are abundant, an overcapacity often leads to the uncontrollable withering process. This problem was the cause of the decreased quality of black tea. Theaflavin (TF) and Thearubigin (TR) were chemical substances that positively correlated to the black tea quality. This research conducted to characterize TF and TR quality in two-stages chemical withering. This research treatment consists of two treatments, namely treatment A (plus season), treatment B (minus season), and one control/routine production (treatment C). Treatment A and B used 25 kg of fresh tea shoots to be withered, the first stage was to wither the leaves until it reached 60%, 65%, and 70% of water content. The second stage was to blended those leaves at the first stage and withered it until it reached about 54-56%. For treatment A and B, the enzymatic oxidation (fermentation) time used 90 minutes. Treatment C used 25 kg of fresh tea shot that processed as normal routine production of black tea orthodox-rotor vane process, with enzymatic oxidation time 110 minutes. Every treatment was repeated 3 times. Treatment A produced TF of 0,97% d.b and TR of 15,39 d.b. (ratio 1:15,97). And treatment C produced TF of 0,92% d.b and TR of 13,69% d.b. (ratio 1:14,82). It was concluded that two-stage chemical withering was able to maintain the chemical and organoleptic qualities of black tea.
