INTRODUCTION
Islamic banking emerged because financial institutions that were only conventional banks and the emergence of Islamic financial institutions in Indonesia after Law No.10 of enactment of this law has triggered the birth of new Islamic banks, both in the status of commercial banks and sharia business units.
The Analyze that are always used to measure performance in the bank, especially in the field of finance is profitability ratios and the ratio of liquidity. With the analysis of banks can evaluate the state financially in times past and the present and projecting the results that will come. State financially in times past and present can be evaluated so it can be known performance (Sumarta & HM, 2003).
Banks based on sharia principles operate on the basis of sharia or Islamic regulations. In this procedure, Islamic banks avoid activities that contain elements of usury and are filled with investment activities on the basis of profit sharing. In operation, Islamic banks are clearly no different from the objectives of other conventional banks, namely to gain as much profit as possible. However, what distinguishes it is that the profits obtained by Islamic banks are used not only for the interests of owners or investors, but are used for the bank's business itself (Trinugroho et al., 2017).
Liquidity relates closely to profitability, because of liquidity indicates the level of availability of capital employment companies are sufficient so that companies do not encounter difficulties in operation. However, on the one hand, excess working capital indicates that the company's management is not optimal because there are funds that are not productive. Management must ensure the availability of capital employment companies are sufficient, so no shortage of capital and also not there funds that clicking the wine.
Companies that do not have sufficient working capital cannot pay their short-term obligations on time and will face liquidity problems that will disrupt the company's day-today operations. Working capital requires good and healthy management because excessive use of working capital indicates unproductive funds. However, if the company lacks working capital, the company will lose the opportunity to make a profit. The end result of working capital reflects the success of company management (Taiwo et al., 2017).
Capital work is one of the sources of power that is important for the company, bleak capital of work net, which is the difference between total assets smoothly with total debt smoothly. Working capital is used to finance the day-to-day operations of the company, it is hoped that the funds that have been spent can be returned in a relatively short period of time (Trinugroho et al., 2017).

The framework describes the relationship of the independent variable, in this case working capital (X1) to the dependent variable, namely financial performance (Y) at Bank Syariah Mandiri Jambi.
According to , Financial management is the management of financial functions. These financial functions include how to raise funds (raising of funds) and how to use these funds (allocation of funds ). The financial manager has an interest in determining the amount of assets worthy of investing in various assets and selecting sources of funds to spend on these assets ".

Working capital
Capital work is divided on two when seen from the balance sheet that is "capital actively " is capital that is listed in the next discharge of the balance sheet, which describe the forms in which the entire funds were obtained in planting right, while the notion of "capital passive" is capital that listed on the next loan of balance sheets that describe the sources from which the funds in acquired. The elements of active capital will always change, will always change in a short time (cash, inventory, accounts receivable). Meanwhile, the value of passive capital within a certain period is relatively permanent (Anwar & Ali, 2018).
Based on the method and duration of active working capital turnover can be differentiated into: -Current asset -Fixed assets Current assets are assets that are depleted in one turn in the production process, and the turnover process is short-lived (generally less than one year). Judging from the definition of working capital itself, from several concepts, current assets are elements of working capital.
What is used to determine the amount of working capital in this study is: Working Capital = Current Assets -Current Liabilities At knew their three capital concept of work, namely: The concept of quantitative, describing the whole (amount) of assets smoothly, where assets well is all spin and can return to the form of the original in a period of time short. The concept is in call with capital work gross -gross working capital.
Quality concept, It is the difference between assets smoothly on top of debt smoothly, or a portion of the assets of current that actually can be in use to finance the operations of companies without waiting for liquidity. The concept is in call with a netnet working capital.
Functional concept, tacking emphasis on the function of the fund in generating revenue income from the business principal company. Generate revenue in the period accounting (current income) and the period of time the next (future income).
This concept is the last of the three concepts based on the function of generating (income). Because every fund that is worked on or used in the company is intended to generate income, given that the funds are used entirely, only a portion of the funds for use is operating in an accounting period which are entirely direct to generate income for that period, and some of these funds are used during that period, but entirely used to produce.
There are two concepts of working capital, net working capital and gross working capital.
1. The concept of capital working net (net working capital), the concept is a difference in the value of money between assets smoothly and liabilities term is short, this is one of the measurements to see the extent to which the company is protected from problems of liquidity.
2. The concept of capital work is dirty (gross working capital), the concept is based on the administration of the kinds of assets smoothly companies namely, cash and securities worth (securities and securities) are in perjual traded, accounts receivable and inventory as well as funding (especially liability period shorter (which required to support current assets ). Thus in the two concepts mentioned above, that each concept has a fulcrum or in other respects each function that is interrelated with one another. So the working capital used in company operations is still active in carrying out its activities .

The smaller or lower the turnover rate, the higher the need for working capital and vice versa. Thus, a high enough inventory turnover is required in order to minimize the ratio of losses due to price reductions and to save costs for storage and maintenance of supplies.
