Abstract

Crafts copper and aluminum metal is well known as the only craft villages featured in Bambu Kuning  District Boyolali which is the center of industry UKM need to be given guidance and training , especially for UKM that there is little need of such a helping hand for community service programs ( IbM ). IbM basic selection service programs to improve the quality and productivity of  the aluminum craft in which the earlier process of making traditional , manually ( using hand -made) in order to become more mechanical craft aluminum kitchen equipment especially produced more precise form, include : Improvement of the manufacturing process of aluminum kitchen utensils mechanically, Design a simple hydraulic press tools according to their ability to operate and care for craftsmen improvement of more uniform product specifications in order to look more attractive.The method offered on IbM activities provide training and guidance to craftsmen on how to operate the hydraulic press tools properly and correct , also perfect the shape of the product so that the resulting shape kitchen tools more precise, more improved quality and can be sold at a higher price also to the wider marketing and export between islands . Plan that will be implemented to produce products in accordance with the Standard of food quality ( SII ) , starting from :1. Improvement of human resources with training and consultation on technology printing process2. Technology improvements equipment by designing a simple hydraulic press toolsTarget outcomes kitchen appliance is able to sell the product in accordance with the SII marketing broader, reaching levels of economical operation in the field of technology , management and promotion through the integration and synchronization of marketing flows from the point of production to the level of use of the product by the user or the user.

Abstract

Abstract Freezing is one way of preserving food for maintaining the quality before consumption. Frozen foods which are now circulating in the supermarket are not given yet a tool to monitor whether the food is never experienced thawing (melting) for some period. In the frozen product that has undergone uncontrolled thawing will increase microbial content rapidly at increasing temperature 10 0C. In this study the temperature-time estimator tool manufactured for frozen beef products and shrimp. This estimator tool consists of citric acid and blue litmus paper. The response will appear in blue litmus paper that changes the color becomes red when positioned at the undesired temperature. In this study, the temperature-time estimator tool is made from citric acid 1.1%, cotton and litmus paper packed in cellophane. The response is influenced by the position of estimator tool and this tool-time temperature estimator can be applied for frozen beef products and shrimp. Keywords: beef, frozen, indicators, shrimp

Abstract

Abstract   Oil production process with fermentation is one of method to produce virgin coconut oil (VICO). In this research, fermentation process done with coconut extract fermentation method as substrate, with biocatalysator, are Rhyzopus oligosporus, Rhyzopus orizae, body of crab and bromelin enzyme from raw pineapple. Design which used is a completed blocked random design. Source of variation is comparison of starter and substrate. From research which has done by biocatalysator, the most effective is Rhyzopus oligosporus with comparison starter and substrate 0,75 : 1, with velocity agitation 150 rpm, produce efficiency 90,23 % test of peroxide number until five weeks keep is 2,7-4,4, acid number 0,02, iod number 8,1, this result is comformable with food oil standard.   Key words : coconut extract – fermentation – Virgin coconut oil (VICO)
