SCGC Concrete (Self Compacting Geopolymer Concrete) has the advantage of being easier and more effective in casting, so it can be applied to strengthening building structures, including the Concrete Jacketing method and voute / haunch beam. This reinforcement method is a form of composite concrete application with different concrete ages, which consists of existing structures with conventional concrete material and jacket or haunch section with SCGC concrete material. This study aims to determine the characteristics in the form of direct tensile strength, flexural tensile strength, and pull off tests (bond test) to test the strength of adhesion between concrete joints. Making specimens consists of 4 x 4 x 16 (cm) flexural tensile test beams, and 15 x 15 x 60 (cm) pull off specimens, and direct tensile specimens in the form of numbers 8. The principle of making test specimens is done by casting twice The first casting is done on the first half of the mold, then wait until the concrete age is 28 days. Then a second casting is carried out in the next half, until the concrete age is 28 days. So that the total age of concrete in making connection test specimens is 56 days. From the results of this study it was found SCGC concrete has a higher adhesion than conventional concrete so that SCGC concrete can be applied for structural reinforcement.

Production on May 2019, PT X produced 29,159 kg of Tortillas to be marketed domestically and abroad. The large amount of production shows the high consumer interest in Tortilla, which makes PT X produce large quantities in 1 month. Production of 29,159 kg was completed in 3 weeks with 3 shifts in 7 working days in the first and third week, and 6 working days in the second week. Inaccurate production planning makes Tortilla production exceed warehouse capacity, indicating that the production process is still running even though the number in June is as much as 17,346 kg and 26,835 kg in July resulting in overproduction of 6% in May 2019 and 15% in June 2019 so that there was an increase in July 2019 to 50%. The implementations of the Artificial Neural Network (ANN) method based on Particle Swarm Optimization (PSO) using the Steepest Ascent Hill Climbing Algorithm (SAHC) areoptimize the final mean flow time by 51%, reduction in makespan by 0.5 in MayJune and 0.1 in July, and a reduction in lateness by 13% after reprocessing results in an optimization that can overcome the problem of overproduction.
