This research aims to determine the regional core competencies to strengthen the city of Payahkumbuh's Regional Innovation System by developing processed livestock products such as Rendang, a traditional dish popular in the Province of West Sumatra. Rendang is processed meat obtained from a long low-temperature cooking process using chilies and coconut milk. The city of Payakumbuh, located in West Sumatra, is one of the centers for the rendang processing industry that produces different types of rendang products including beef rendang, chicken rendang, egg rendang, lung rendang, sweet potato rendang, etc. This research discusses the added value of rendang products as an effort to increase the food industry to increase competitiveness and food production within the framework of a regional innovation and development through livestock product processing industry. Primary data were obtained through interviews with actors within the rendang industry. While secondary data derive from rendang industry literature. The data analysis used is the value-added analysis drawing on the Hayami method. The results show that the highest ratio of added value is egg rendang product (16.19%), followed by lung rendang with a value-added ratio of 8.44%.

Utilization of the potential energy of water scale piko hydro is still very small, one of the challenges is that water turbines are not sold freely on the market, to get it must be ordered in advance to certain shops or workshops so that the price of turbines becomes expensive. The purpose of this experimental research is to analyze the performance of alternative fluid engines that can function as water turbines, namely pumps as turbines (PAT). Tests were carried out on three sizes of centrifugal pumps, namely 1 inch, 1.5 inches and 2 inches. using the same test equipment. The test results found that centrifugal pumps can be used as a good alternative as a water turbine. The larger pump size results in a lower head, power and efficiency. The results of testing at constant rotation and head, PAT 1 inch superior to PAT 1.5 inches, and PAT 2 inches. The maximum power and efficiency of 1 inch PAT is 235 W and 38% occur at a constant head of 15 m, 4.1 L/s discharge and 850 rpm rotation. This data inspired the researchers to create head and discharge standards suitable for each PAT size. Furthermore, many centrifugal pumps are sold in the market, it is necessary to do further research to get the right recommendations about the type, brand and size of the ideal pump used as a pico hydro scale water turbine in accordance with the potential for water and head discharge in the community.
