<![CDATA[Electrical energy is energy that has an important role for society. One of the benefits of electrical energy is for lighting. The need for electricity in the world today is very large. The source of energy used to obtain electricity is still mostly using oil and gas and coal, where oil and gas on earth is very limited, and at some point it is estimated that it will run out. With this problem, one of the renewable power plants that can be utilized is the MHP system (Microhydro Power Plant). MHP is a small-scale hydroelectric power plant by utilizing water from irrigation canals, dams, and rivers that have low head. The utilization of this power can be done by converting it into mechanical energy using a screw turbine type water turbine (Screw Archimedes) with a discharge of 0.01 m³/s, a length of 870 mm, a thread diameter of 350 mm, a shaft diameter of 190 mm with a shaft thickness of 5 mm, 6 blades which divided into 2 threads and a shaft tilt angle of 35°. This research was conducted to simulate the performance of a screw turbine using solidworks software. This study serves to obtain critical points due to fluid pressure on the screw turbine and to analyze the water fluid when the screw turbine is operated.]]>

<![CDATA[Human resources play a very significant role in the running of an organization or company to manage the running of the company's system optimally so that it can support the achievement of the goals of the organization or company. But the problem that is often faced by companies today is how to create human resources that can produce optimal performance and in accordance with what the company expects. This research was conducted at a fertilizer plant in the city of East Java with the main activity of supplying national fertilizer needs. This company includes advanced companies so the demand for fertilizer production is also increasing. With these conditions, the role of employees becomes an important factor for the company in realizing the vision and mission of the company. The company always strives to improve the internal quality of the company in order to compete with competing companies. One of the efforts made is an assessment of employee performance and team work. The purpose of research is to assess the influence and interrelationships between dependent variables (organizational culture) and independent (employee performance and team work). This research population is employees in fertilizer companies who understand the problems and people who are experts in their fields to ensure the data generated is relevant and in accordance with the purpose of the research. The sample used to fill out the variable questionnaire amounted to 52 employees.The methods used are statistical analysis of multiple linear regression, test F and coefficient of determination. The results of research and analysis conducted by researchers showed that independent variables namely team work (X1) and employee performance (X2) simultaneously or together had a positive influence and significance on dependent variables namely organizational culture (Y). Or in other words, if the dependent variable increases, it will be accompanied by an increase in independent variables.]]>
