Abstract

It has been investigated about the analysis of characteristic, of cement which used the natural pozzolan in Aripan Solok region in analyzing the blaine, normal consistency and setting time. This research is aimed to recognize the infuencial characteristic of additional natural pozzolan to setting time, blaine and normal consistency. The testing characteristic of natural pozzolan to cement used devices vicat and blaine, the testing pracess was done in some variatation of percentage of 0%, 5% and 9.5 %. The result ot the reseach indicated that the characteristic of addition of natural pozzolan to cement which fulfil SNI 152049-2004 could make the setting time longer in cement hidration and it needed a big volume of water as the normal consistensy. Addition of natural pozzolan in cement will influence the blaine of cement it tells about the maximal addition of natural pozzolan 9.5 %to indicates the blaine of cement to be rough.

Abstract

In the face of the Revolution industry 4.0, global connection, artificial intelligence, and automation have disrupted technology. This made the industrial world's development in work competition, not linear and even created new jobs. Digital talent and innovation are needed to face the world of work. This study discusses the construct effect between digital talent, individual innovation behavior, and Skills Revolution Industry 4.0, and the effect of Skills Revolution Industry 4.0) as a mediator to digital talent constructs' relationship. Data collection is obtained directly (face to face). Samples were previously clustered by sampling technique. Questionnaires use the Likert Scale. Then, the data gotten were processed by SEM-PLS with Software 3.8.2. The result showed that digital talent has a positive effect on individual innovation behavior. This meant that skill of revolution industry 4.0 as a construct mediator was successful. The stronger digital talent influences, the stronger individual innovation behavior influences, and it is accelerated with revolution industry skills 4. This study proposes a model to build mastery of digital talent and individual innovation behavior of Universitas Andalas students through the mastery of skills of revolution 4.0 as a mediator. This research can pave the way to improve students' readiness in facing the world of revolution 4.0, one of which is in the field of digital innovation.
