Judul: ANALISIS KRITIKAL POIN DAN IMPLEMENTASI DAN IMPLEMENTASI PROSEDUR OPERASIONAL BAKU MINUMAN JAHE INSTAN HERBAL DI CV. SARI SEHAT
Abstrak: Red ginger is one of the most popular agricultural commodities in Indonesia because of the properties it contains. CV Sari Sehat is a micro-scale UKM that produces processed ginger products in the form of powdered drinks. Unfortunately, the production process for CV Sari Sehat products does not have certain standards, so the final product quality is not uniform in each batch of production. In this study, the preparation of Standard Operating Procedure (SOP) documents is the result and a solution to the problem of non-uniformity in the quality of the final product at CV Sari Sehat. There are eight important sections in the document SOP including production standards at each step or process, up to the form of the validation process. In the making of SOP documents, food safety is also one of the supporting aspects where critical points can be found through the Hazard Analysis Critical Control Point method. The critical point in the production process is cooking which requires temperatures above 100°C to remove harmful microorganisms.

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.
