Changes in leaders in an organization are common and will affect all units from the management level to implementation. This is related to the leadership style and organizational culture developed by new leaders, especially in terms of motivating and providing job satisfaction in achieving the best performance. This research is explanatory research that proves a causal relationship between work motivation, transformational leadership, organizational culture, and employee job satisfaction as a mediating variable on employee performance. The study also aims to see whether or not two or more variables have a relationship, and how significant the relationship is and how the relationship is going. In this study, to analyze and find out the significant level, and the relationship between variables, the structural equation model analysis method is used. The results of the study on 385 respondents who were a sample of research in educational foundations that shelter educational institutions from early childhood education to university level that are spread in almost all regions of Indonesia showed the need for special attention to work motivation which did not significantly influence job satisfaction and satisfaction work does not mediate employee performance against motivation, leadership, and organizational culture variables. Other results indicate that the variables of work motivation, organizational culture, and transformational leaders significantly influence employee performance.

Small and Medium Enterprises (SMEs) have a very important role in the development of the Indonesian economy. Special Region of Yogyakarta (DIY) is one of the provinces that has many SMEs. The SMEs has the potential to penetrate the international market, one of which is a wooden handicraft SMEs. Woodencraft can be used as a cluster because it fulfills three factors that enable it to compete in the international market, namely the factor of global market needs, the factor of superior products, and potential SME product factors. However, woodencraft SMEs still face obstacles in product penetration abroad, namely obstacles from internal SMEs, the government, and international markets. The solution offered to help woodencraft SMEs to go international a program called Integrated Woodencraft Cluster, which is a cluster of woodencraft SMEs that integrates supply chain management (SCM) based distribution systems with four main lines (suppliers, production, sales, and information), internet-based information systems, and Just In Time (JIT) principle. The program involves local government, civil service, wood handicraft SMEs, suppliers of raw materials, and academics. The advantages of Integrated Woodencraft Clusters compared to conventional clusters include having a clear vision for exporting production, a structured managerial system, having an export agency, supplying raw materials, clear lines of information, and being able to facilitate all SME woodencraft, both on a small scale and intermediate.

Accreditation is a government assessment for a Higher Education. Based on the regulation of the minister of education and culture of the Republic of Indonesia number 87 of 2014 article 6, the validity period of the accreditation status and ranking of accredited study programs and tertiary institutions is 5 (five) years. During this time, the institution must prepare the documents used for accreditation. In 2019, the government has implemented changes to the standard accreditation assessment criteria of an institution, the evaluation of accreditation documents refers to several documents, one of them is Study Program Performance Sheet (LKPS) which is recapitulated in an excel. This research focuses on data integration at LKPS. In the LKPS excel data there is a relationship between the data with one another. One of the data that has a relationship is data related to lecturers with tridharma activities. Given that the application of this new rule began in 2019, this research focuses on designing the concept offline, namely Database integration made using Microsoft Access. LKPS analysis results have determined that there are 30 tables of which there are 22 integrated tables and 8 tables that do not have integration.

Decision making by company management is mostly multi-criteria decision making. Multi-criteria corporate decision making is characterized by having to make decisions on several corporate objectives that are mutually contradictory. Service companies generally want to maximize customer satisfaction and minimize company operating costs. Customer satisfaction can be maximized, by implementing programs that are expected to maximize the level of customer satisfaction. Implementation of these programs will increase the company's operational costs, which in turn can reduce company profits. The company's goal to increase customer satisfaction results in increased operational costs, so that it is contradictory to the second corporate goal of minimizing company operating costs, which is a multi-criteria decision making problem.Trade-offs are sought from two contradictory service company objectives, namely maximizing customer satisfaction and minimizing company operating costs, firstly, a multi-criteria decision making model will be developed. The decision-making model developed is a mathematical model consisting of two contradictory objective function functions, namely the maximization of the level of customer satisfaction and the minimization of the company's operating costs, as well as a limitation which is a mathematical translation of the things that limit the achievement of these two company goals. After a mathematical model of multi-criteria decision making is formed, the next step is to look for trade-offs from the two company's goals using the global criterion method.
