Abstrak: This research was consisted of 5 steps i.e. to study the characteristic of Home Industrial Food Product (HIFP) of temulawak instant drink, to improve formulation and process of temulawak instant drink, to determine chemical characteristic of the product, certification of temulawak instant drink product of home industrial scale, and analyses of business feasibility. The first step was to determine the condition of Home industrial temulawak instant drink. The data of this step was used to improve formula and process to obtain standard formula. Besides, determination of Standarad Operating Procedure of home industrial of temulawak instant drink was carried out as further step of the improvement of formula and production process. The second step of this research was to analyse the chemical characteristic of the standard formula’s product using proximat analyses. The propose of certification of Home Industrial Food Product (HIFP) to was carried out as the fourth step. Finally, business feasibility analyses on home industrial scale was done to determine whether this business are feasible or not. Formula III (the ratio temulawak and sugar amount 1:2) was chosen as the most acceptable formula since it showed highest preference level as result of organoleptic test. This formula also had the shortest rehydration period and highest yield. The chemical and phsycal properties of instant temulawak are 1,06% of water content; 2,84% of ash content; 3,51% of fat content; 2,07% of protein content; 90,53% of carbohydrat content; and 33,09% of total sugar with L= +52,53; a= +3,29; b= +29,16 representating the color. This instant Coro has 0,428% of dissoluble part and 28 second for rehydration time. Home industrial of temulawak instant drink considered to be sufficient in GMP application and has acquired HIFP certificate with serial number of6123201021009 from governmental health department. The feasibility study based on investment criteria showed the production of instant temulawak was feasible to be done.

Abstrak: Red ginger have been processed into several foods and beverages, such as instant beverage, ginger candy, ginger pickle, ginger coffee, etc. One of household industry that produces instant red ginger beverages is Jahe Gunung Leutik in Ciampea, Bogor. But, the household industry is still has not applying good manufacturing practices and it is still not has standard formula. Therefore, it is need a deep study to determine the standard formula and to apply manufacturing practices in order to get P-IRT certificate from health department. The methods that used in deciding the best formula are analysis of rehydration time, analysis of color, and hedonic test. The formula that used in the test was formula with ratio sugar and red ginger 1:2 (A), 1:1 (B), and 1:3 (C). After that, product from the best formula will be analyzed with proximate analysis in order to meet the requirement of P-IRT certificate’s submission. Moreover, feasibility analysis will be undertaken in this industry. The results showed that rehydration time in all three samples still include in instant beverages because its rapid rehydration time. Color analysis and hedonic test also showed no significant differences between the samples. Therefore, the formula with the ratio of 1:3 was chosen because it is the cheapest material usage. Moreover, Standard Operating Procedure (SOP) that controlled several aspect on industry from purchasing raw materials, production processes, until product shipment has been created according to the obtained formula. The best formula obtained from this experiment is analyzed its chemical composition and the results of moisture content, ash content, fat content, protein content and carbohydrate content are 1.16%, 1.17%, 0.08%, 0.46%, and 97.13% respectively. And after following several processed of certification, the household industry got the P-IRT number as follow 61232010110099. Feasibility analysis also undertaken by this household industry and the conclusion is this industry is feasible from the financial side.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
