Abstract

Purpose of this study is to determine the optimum conditions of extraction using conventional methods (maceration) and ultrasonic methods by using response surface method (RSM). The variables used in this study is the ratio of solvent with black pepper, temperature and time of extraction. Solvents used in this study is 99% ethanol. The bigest yield of oleoresin using maceration method was  4.42% with a ratio of solvent and black pepper for 1: 4 g / ml and extraction time of 4.68 hours. GC-MS test showed that the piperine contained in oleoresin extracted by using maceration are respectively69.92% FT-IR test showed that oleoresin extracted using maceration have the same bound that same as piperine bound. Organoleptic test showed that oleoresin produced by using maceration meet the requirement of ISO standards 06-2388-1998 (dark brown color, pepper smell and thick paste form).

Abstract

This Community Service (CS) activity aimed to promote the importance of business licensing and legality through the management of Business Identification Numbers (NIB) using the Online Single Submission (OSS) system. Conducted at the P2PAKB Hall of the West Aceh Regency Government, it involved 20 business actors. The program utilized lectures, discussions, and hands-on practice, providing participants with training on NIB registration procedures and insights into its benefits, such as market expansion and legal protection. The results showed that participants successfully understood and applied the NIB registration process while recognizing the importance of business legality. Their active participation in discussions and practical sessions indicated the program’s success. With NIB ownership, business actors are expected to enhance the competitiveness of agricultural products, expand their market reach, and support local agribusiness sustainability. This initiative represents a strategic effort to drive rural economic development through agricultural innovation and improved business legality awareness.
