I. INTRODUCTION
PT. Xacti Indonesia is an Original Equipment Manufacturer (OEM) based company that produces digital products that are then purchased by other companies or retailers using the trademark of the buying company. For now, the product being produced is a digital still camera (Digital Still Camera). At PT. Xacti Indonesia has several divisions to move the company, one of which is the Material Resource Planning (MRP) division. The MRP Division is responsible for managing camera building materials, which will be needed by the production division in manufacturing cameras.
MRP division at PT. Xacti Indonesia categorizes materials for making cameras on shelves, which have been categorized in detail based on the serial number of the material that has been registered since the material came from the vendor received by the Receiving division. MRP division staff operators will take materials according to the production division's requests in producing specific series cameras, then update the stock of goods taken from the ERP system embedded in mobile devices in the form of a compact and portable tablet PC that makes it easier for staff operators to record incoming and outgoing material data on each material shelf in the warehouse a portal application. Before using a tablet PC, the Staff documented the amount of material stock by manually writing it on paper, which at the end of the working day would update the stock on the computer available there.
One of the things that cause companies not to get the benefits and advantages of an ERP system is the reluctance and resistance of users and the company's inability to determine changes in the organizational structure according to the benefits of the technology chosen. [1]. Enterprise Resource Planning (ERP) is a term given to an integrated information system that supports transactions in the form of processed data in managing organizational or company resources that aim to support a company's functions. These resources include funds, people, machines, spare parts, time, materials, and capacity [2]. Enterprise Resource Planning (ERP) consists of a series of integrated software application tools designed to support core business functions [3]. Based on reports at the beginning of implementing the procedure, when the new system was implemented, there were still some employees who had not fully used the tablet PC. It is because there are several obstacles. Therefore they have not fully adapted to using a tablet PC and prefer to use the old manual procedure, which is comfortable and feels that the old procedure has supported their performance well so that it discourages staff operators from using the new procedure. From the problems it was found that the implementation of the portal application embedded in the tablet PC has not been used optimally by staff operators so the focus of this problem lies in the user's intention (Behavioral Intention) to use the latest procedure using the portal application on a tablet INTENSIF, Vol. age, experience, and education. As research conducted by He and Lee states that women have a lower experience using computers because and tend to be more anxious about using computers than men [5]. Improving the system implemented can increase. Staff uses the system more to complete their work than pens and paper (Paper-Based) [6]. It is expected that the MRP division of PT. Xacti Indonesia can increase staff operators' willingness to implement a tablet PC-based ERP system in the future. acceptance. This theory aims to explain user behavior towards information technology used to examine the effect of variables on behavioral intentions [7]. This model results from a review of a combination of eight acceptance models that have been successfully developed previously [8].  Expectancy (the belief that the extent to which the system will help individuals improve their performance), Effort Expectancy (the level of ease of use of the system), Social Influence (the extent to which an individual feels essential that other people believe he should use a new system), and Facilitating Conditions (individual trust in the presence of the company's infrastructure to be used for system use) which all affect Behavioral Intention which will later affect Use Behavior [8]. The UTAUT model is an instrument for company management to assess the success rate of implementing information technology. Besides, UTAUT can also assist management in understanding the aspects that affect the acceptance and use of information technology [3].
This research refers to research conducted previously as a literature review, including Soliman and friends [9]. They researched the modeling of user intention in using the ERP system of universities in Egypt, research conducted by Wagaw [10], namely the acceptance of locally made ERP systems by companies in Ethiopia. From this research, it can be applied the instruments used, such as statement item models and reliability testing techniques which will be used as references in the evaluation of the mobile-based ERP system of PT. Xacti Indonesia. The results of this study can also be used as a reference for the evaluation results of the mobile-based ERP system of PT. Xacti Indonesia considering the results of this research, can also be applied to developing countries like Ethiopia, research conducted by Lukman Hakim [11]. He evaluated public acceptance of the learning site belajarkoding.net Using UTAUT In the method used by Lukman, namely the PLS testing method and the moderator variables using PLS-MGA, which will be used as a reference for evaluating the mobile-based ERP system of PT. Xacti Indonesia on the set moderator variables.

A. Instrument Design
The design of research instruments includes variables, indicators, and items. Questionnaire items in the evaluation of tablet PC-based ERP systems use items that refer to previous studies. It also includes related literature adjusted to the study of operational conditions. Then instrument validity and reliability tests are carried out. Source statement items were adopted from some literature, including source statement items adopted from several kinds of literature, including  the degree to which one believes that using a tablet PC-based portal application will improve their work performance.

Social Factors
MRP Division staff internalization process in using the application that has been provided, which has become a habit of using tablet PC-based portal applications. It can be continued for the pilot study stage, which is a small-scale test by taking a group. The researcher considered to represent the population of this study to test a questionnaire. It has been validated by experts so that it is tested first on the population before taking actual data. [16].
Thirty respondents randomly selected were tested first to test the research instrument that was valid and reliable. The data validity test was conducted to determine the level of data validity and the degree of truth (whether or not an item was valid in the questionnaire given to the respondent) from a data collection process on the research instrument. [13], [17]. The results show that the validity test uses the correlation value of the bivariate Pearson coefficient (r) with the r table with the calculated r-value that has been processed using SPSS calculations. There is 1 item statement that is invalid because the value of r does not meet the value of the r table, so that the statement is not used and is deleted from the study [12], [13], [17], [18]. To test the reliability using the Cronbach's Alpha technique. The result states that all variables are declared reliable because they have a Cronbach's Alpha value above 0.6.  The first stage of testing is the outer model test. This test is conducted to determine the regression value of a reflective latent variable on the indicator that represents it [19] However, items that do not meet the convergent validity requirements need to be removed from the research model [12], [13] to avoid problems at a later stage. as the convergent validity test, which has a Cross Loading value below 0.7 so that the two items are removed from the model. [12], [13].

III. RESULT AND DISCUSSION
The reliability test was conducted to determine the extent to which the measurement results in this study were reliable. The reliability test is calculated by measuring the Cronbach Alpha value and Composite Reliability. If the test value is above 0.7, then the variable is reliable [20]. Based on the results of the reliability test presented in table 3 using Cronbach's Alpha and composite reliability, it shows that all variables show a number above 0.7, which states that the condition of the variable is reliable.

D. Test of Moderator Variables
For the evaluation of structural models influenced by gender moderator variables, the PLS-MGA (Partial Least Square-Multigroup Analysis) method is carried out. It examines whether there is an influence or intervention from the moderator variable on the independent variable's relationship with the dependent variable, a feature found in the application. SmartPLS 3.Significant results are indicated at an alpha of 5% of the error rate if the p-value is less than 0.05 or greater than 0.95 for specific differences from group-specific path coefficients. [22], [23].
Moderator variables can be interpreted by dividing the overall data into two sub-sample groups.
By finding the cut-off point or mean value in a sample, the sample can be divided into two groups [11]. Table 5 shows the PLS-MGA results on the gender moderator variable obtained from the PLS-MGA Report using SmartPLS. The results state that the overall moderator variables, namely gender, age, and experience tested, do not interfere with any relationship between the independent variable and the dependent variable.  [13], [21], [23]. Based on tstatistical testing results, the hypothesis testing model can be described, as shown in Figure 4.  Based on the results of testing the third hypothesis, it shows that Social Influence will affect Behavioral Intention in using a tablet PC-based ERP system. Itis based on the original sample value of -0.213, which means that it leads to a negative relationship and a t-statistic value lower than the t- The results of the test show that only the Performance Expectancy variable is proven to affect behavioral intention (intention to use). Hence, it is seen that the perception of staff operators regarding the usefulness of using the Glovia portal application for work, accelerating work, and increasing productivity and performance affect the intentions of division staff operators. MRP to use the tablet PC-based Glovia portal application.

F. Recommendation
Based on the test results, the effect of Performance Expectancy on Behavioral Intention is proven to significantly affect Behavioral Intention in the use of tablet PC-based ERP systems at PT. Xacti Indonesia. It is necessary to conduct regular socialization to increase their work productivity and interest. They will experience more benefits and improve performance when using the Glovia portal application compared to updating stock material manually using a pen. and paper. According to Marler, Dulebohn, and Liang, who was cited in Asa's research [17] stated that the training carried out by an organization when implementing a new system fulfills at least two important objectives, namely that the organization must facilitate learning how to use the system to be implemented to users. Staff operators must know how to use the Glovia portal application according to the features presented by the application so that the results of the work they produce are better with the work they produce when using the previous system. Second, the training conducted for users must form a positive attitude towards the system to be implemented

IV. CONCLUSION
In the Performance Expectancy variable, the researcher concludes that based on the study results, there is a significant influence on the Behavioral intention variable in using the tablet PCbased Glovia application used by the Operators Staff of the MRP division of PT. Xacti Indonesia.
It indicates that the Staff Operators feel that the glovia application is influential. Especially in improving their performance in recording material stocks using a mobile-based ERP system using a tablet PC compared to using the previous procedure manually using paper material for stock list templates and pens. Moreover, their productivity is also increased more than the previous procedure, which makes the execution of their work can be completed more effectively moderator variable. Suggestions that can be given are expected in future studies to examine other variables that influence the Behavioral Intention variable so that the research results obtained will be better. Although the characteristics of dynamic users are because 50 percent of the population are contract employees (outsourcing), it is hoped that this research can be used as a reference for further evaluation research.
