E-marketplace INTRODUCTION The necessity to pursue the satisfaction in purchasing and selling has of ways.
This is done in order to get the mutual satisfaction in the transaction.
Shopping that is currently in demand is online shopping as it can be done anytime and anywhere.
For instance, e-commerce business models, that can be done anytime and anywhere, just like e-marketplace.
E-marketplace is an internet-based online media which conducts business activities and transactions between buyers and seller (Putra et al.
, 2.
Good online communication will increase trust between sellers and consumers (Bao et al.
, 2.
One of the variables that can influence users to intend to use the E-market place is perceived usefulness 170 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 (Setiyadi et al.
, 2.
E-market place needs to offer the same concept as traditional markets.
This eases the sellers to meet their customers.
The simplicity offered by the E-marketplace makes it faster known, many even describe the E-marketplace as a Department Store.
The expansion of the E-marketplace has almost dominated various parts of the world.
The results of the Sharing Vision survey in 2018 stated that 92% of online consumers shop through the marketplace and 50% use social media.
The number of internet users in Indonesia reached 88 million until almost the end of 2014, while the total population of Indonesia was around 253 million, hence, it is estimated that internet users reached 34.
9% (Fachriyan & Wijaya, 2.
With the increasing number of internet users in Indonesia, it certainly benefits E-Marketplace owners in Indonesia such as Bukalapak and Tokopedia as well as other E-Marketplace holders.
Seeing the increasing number of internet users in Indonesia, the opportunity to become an E-Marketplace holder is very possible and profitable.
Even since the inception of the E-marketplace, it has provided opportunities for new entrepreneurs to start or expand their business (Wiradinata, 2.
The high interest of E-Marketplace users in Indonesia makes Indonesian scientists want to know the extent of the role of the Indonesian people in accepting the development of online In fact, many studies mention that research on e-commerce in the world is currently an interesting topic to research (Farki & Baihaqi, 2.

Sampit has a very fast economic development.
Economic progress is supported by the easy entry and exit of various products, both through seaports and airports.
In addition to these conveniences, in Sampit City there is a Shopping Center called Pusat Perbelanjaan Mentaya (PPM), often visited by people and visitors from outside the city to conduct business transactions.
Progress in various fields is currently being matched by the development of information technology that can make it easier for everyone, such as in online transactions.
Online meetings require a high level of trust because the seller and the buyer do not meet in person.
Based on the problems described above, it is necessary to know the level of public trust in online transactions.
This can help develop an online transaction system in addition to the features required by customers.
This research is intended to recommend the development of an EMarketplace application in Sampit city.
By conducting research on the community in Sampit and its surroundings regarding the level of trust in conducting online transactions.
So that the development of applications can later meet the needs of sellers and buyers on the side.
METHODS
The phases of the research carried out are problem identification, literature study, formulating problems obtained in the identification process, designing models, compiling questionnaires based on interviews and literature studies, testing the validity and reliability of questionnaires, data collection and model validation, analysis of results, conclusions and 171 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 Figure 1 Research Methodology 1 Sampling and data collection This research object is the e-marketplace in Sampit and the subject is the user, the data source in this research comes from online and offline surveys.
Online samples are conducted through online forums by spreading online questionnaire by google form and offline samples are conducted by distributing questionnaire at Pusat Perbelanjaan Mentaya Sampit.
The number of sample size is calculated using Hair formula collecting 224 valid responses from a total of 240 responses, hair formula is used because the population size is not known with certainty.
2 Instruments and measures The measurement instrument in this research is the surveys by spreading online and offline questionnaire, the questionnaire includes three sections.
The first section had demographic questions about the respondents.
The second section asked respondents what kind of e-marketplace they had used and the third section had questions measuring the variables in the proposed model.
The questions given in the third section is about perceived ease of use(PEOU), perceived usefulness(PU), attitude toward using(ATU), behavioral intention(BI), actual usage(AU) and shopping enjoyment(SE).
The questionnaire scale is using likert scale from 1(Strongly Disagre.
to 5(Strongly Agre.
Research data is processed and tested using Structural Equation Model (SEM-PLS) and WarpPLS as a tool, there are two stages of model analysis in SEM-PLS which is : measurement model or the outer model and structural model or inner model.
3 Conceptual Model The model used in this research is TAM and flow theory, there are six variables in this perceived ease of use, perceived usefulness, attitude toward using, behavioral intentions.
Intention, actual usage and shopping enjoyment.
172 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 Figure 2 Conceptual Model of This Study The conceptual model in Figure 2 above, it is known that the hypothesis is as follows:
H1 - Perceived Ease of Use (PEOU) is related positively to the Perceived Usefulness (PU).
H2 - Perceived Ease of Use (PEOU) is related positively to the Attitude Toward Using (ATU).
H3 - Perceived Usefulness (PU) is related positively to the Attitude Toward Using (ATU).
H4 - Perceived Usefulness (PU) is related positively to the Behavioral Intention (BI) H5 - Attitude Toward Using (ATU) is related positively to the Behavioral Intention (BI).
H6 - Behavioral Intention (BI) is related positively to the Actual Usage (AU) H7 Ae Shopping Enjoyment(SE) is related positively to the Behavioral Intention(BI) RESULTS AND DISCUSSION 1 General description of the characteristics of the respondent Respondents in this study are general consumers who have made transactions at the Pusat Perbelanjaan Mentaya (PPM), which is one of the markets in Indonesia.
The number of respondents obtained in this study was 240, after sorting there were 224 respondent data that were suitable for analysis.
Respondent data to be analyzed is obtained from various characteristics, for example gender, age, occupation, city, ever used e-marketplace, e-marketplace used, how many times a month use e-marketplace, how many hours a month visit e-marketplace, and how often to visit e-marketplace.
The prescription data obtained in the study were 48% female and 52% male.
The data collected also shows the age of respondents 10-24 years 44%, age between 25-34 years 47%, ages between 35-44 years 7%, and ages between 45-55 years 2%.
Moreover, if it is viewed from work or status, it is obtained that 31% of students, 33% of workers, 9% of housewives, 10% are selfemployed, and 17% answered others.
Respondent data obtained came from several cities.

In essence to obtaining information about the demographics of the respondents, this research also receieves the information about respondentsAo experiences in using the EMarketplace.
Based on the data obtained by 240, it is known that 224 respondents have used the e-marketplace.
It also obtained the data on the types of e-marketplace used by respondents.
respondents used Shopee, 16 respondents used shopee, 10 respondents used Lazada, 5 respondents used Bukalapak, and 18 respondents used other types of e-marketplace.
Other respondents have used various types of e-marketplaces.
173 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 The research results also obtain information related to the frequency with which someone uses e-marketplace services.
It is known that the majority of respondents visit the e-marketplace every few months, namely as many as 61 respondents.
It can be concluded that the majority of respondents visit e-marketplaces to shop or look for products / services only when they are in need.
Then obtained information about the length of time the respondents visited the e-marketplace on average less than one hour.
As seen from how often respondents visit the e-marketplace, it is known that 86 respondents use the e-marketplace normally.
2 Processing of Survey Results The result of data collection, shows that Perceived Ease of Use and Perceived Usefulness has the most positive responses.
, it has mean value of 4.
Attitude Toward Using variable has the smallest response.
A description of the mean value of each variable can be seen in Table 2.

In table 3, it is known that the p value is significant, which is less than 0.
05 and of all loading indicator values there is a loading indicator value that is less than 0.
In the other cases, 174 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 according to Sholihin, the requirements for loading values above 0.
60 are often not fulfilled, especially in the case of newly developed questionnaires, therefore, the loading indicator value still needs to be maintained.
According to Hair indicator with loading below 0.
60 it should be removed from the model.
However, the decision to remove indicators with loading values below 60 should first analyze the impact.
This indicator can be removed if it can increase AVE and composite reliability above the limit.
From the above statement, it is considered to maintain the indicator with a loading value below 0.
60 because the AVE results and the composite reliability indicator with a loading value of 0.
60 meet the acceptable threshold.

Effect Size is calculated from the absolute value of the individual contribution of each latent predictor variable to the R-squared value of the latent criterion variable (Cohen, 1.
According to Kock and Hair in their research cited by (Sholihin & Ratmono, 2.
effect size can be grouped into three weak .
, medium .
, and large .
The effect size value below 0.
indicates that the influence of the latent predictor variable is very weak from a practical point of view even though it has a significant P value.
Table 6 above summarizes the effect size of the latent predictor variables on the latent criterion variable.
[H.
- Perceived Ease (PEOU) is related positively to the Perceived Usefulness (PU).
The results of the Model Test in table 6 present the relationship between the PEOU variable and the PU variable, which has a path coefficient value of 0.
763 and a p value <0.
These results indicate that the two variables have a significant relationship.
Hence, hypothesis 1 in this study is accepted.
In testing the structural model it also shows that the relationship between the predictor variables for the perceived ease of using the e-marketplace and the criterion variable for the perceived benefits of e-marketplace has an effect size of 0.
582, this value indicates that the perceived ease of using a large e-marketplace variable from a practical point of view has a P value significant.
[H.
- Perceived Ease (PEOU) is related positively to the attitude toward using (ATU).
In Table 6, the Model Test Results presents the relationship between the PEOU variable and the ATU variable, which has a path coefficient value of -0.
165 and p value <0.
These results indicate that the two variables have a significant relationship.
Thus Hypothesis 2 in this study is accepted.
In testing the structural model it also shows that the relationship between the perceived ease of using e-marketplace predictor variables with the criterion variable of the attitude of using emarketplace has an effect size of 0.
073, this value shows that the perceived ease of using emarketplace variable is weak on a practical point of view and has a P value significant.
[H.
- Perceived Usefulness (PU) is related positively to the attitude toward using (ATU).
In Table 6, the Model Test Results presents the relationship between the PU variable and the ATU variable, which has a path coefficient value of -0.
38 and a p value <0.
These results indicate that the two variables have a significant relationship.
Thus Hypothesis 3 in this study is accepted.
In testing the structural model it also illustrates that the relationship between the predictor variables for perceived benefits using e-marketplace and the criterion variable for the attitude of using emarketplace has an effect size of 0.
190, this value shows that the perceived benefit variable using e-marketplace is medium on a practical point of view and has a P value.
[H.
- Perceived Usefulness (PU) is related positively to the behavioral intention (BI).
In Table 6, the Model Test Results presents the relationship between the PU variable and the BI variable, which has a path coefficient value of 0.
037 and a p value <0.
This result shows that the two variables have a significant relationship.
Thus Hypothesis 4 in this study is accepted.
In testing the structural model it also shows that the relationship between the predictor variables for perceived benefits using the e-marketplace and the behavioral intention criterion variable has an effect size 026, this value shows that the perceived benefit variable using the e-marketplace is weak in practical terms and has a significant P value.
[H.
- Attitude toward using (ATU) is related positively to the Behavioral intention (BI).
In table 6, the Model Test Results presents the relationship between ATU and BI variables, having a path coefficient value of -0.
027 and a p value of 0.
This result shows that the two variables have an insignificant relationship.
Thus, hypothesis 5 in this study is not accepted.
Then the structural 177 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 model test shows the relationship between the ATU variable and the BI variable has an effect size This value indicates that the variable relationship is not significant.
[H.
Ae Behavioral Intention (BI) is related positively to the Actual Usage (AU).
The Model Test Results presents the relationship between the BI variable and the AU variable, which has a path coefficient value of 0.
66 and a p value <0.
This result shows that the two variables have a significant relationship.
Moreover, hypothesis 6 in this study is accepted.
In testing the structural model, it also shows that the relationship between the BI predictor variable and the AU criterion variable has an effect size of 0.
952, this value shows that the BI variable is large from a practical point of view and has a significant P value.
[H.
Ae Shopping Enjoyment (SE) is related positively to the Behavioral Intention (BI).
The Model Test Results presents the relationship between the SE variable, has a path coefficient value of 0,968 and a p value <0.
The result shows that the two variables have a significant relationship.
Moreover, hypothesis 7 in this study is accepted.

Not Accepted Accepted Behavioral Intention(BI) is related positively to the Actual Usage(AU) Accepted Shopping Enjoyment(SE) is related positively to the Behavioral Intention(BI) Hypothesis 1 is known that there is an effect of perceived ease of use (PEOU) on perceived usefulness (PU), this is due to the fact that the ease of operating e-marketplace services affects the results obtained from these uses.
Ease of operating e-marketplace services affects users so that sales and purchase transactions using e-marketplace services become more effective, faster.
This result is in line with research (Lu et al.
, 2.
, (Pavlou, 2.
which states that convenience perceived ease of use (PEOU) has a very significant effect on perceived usefulness (PU).
Hypothesis 2 is proven that perceived ease of use (PEOU) has an influence on attitude toward using (ATU).
The results of this study indicate that e-marketplace service users feel that using e-marketplace services will increase the effectiveness and efficiency of the transactions they make, such as sales transactions, purchases, search for products or services according to what they Therefore, when users feel that using e-marketplace services is useful, comfortable, and provides convenience, they do not refuse to use e-marketplace services.
The results of this study support previous research conducted by (Adams et al.

suggest that perceived ease of use has an influence on attitude toward In addition, this imperis study is in line with other research conducted by (Venkatesh & Davis, 2.
, (Bruner & Kumar, 2.
, and (Kulviwat et al.
, 2.
and also suggests that there is a positive influence on perceived ease of use (PEOU) on attitude toward using (ATU).
In hypothesis 3 testing, it can be seen that the perceived usefulness (PU) that have a positive effect on attitude toward using (ATU) are accepted, this shows that when users of e-marketplace 178 | P a g e Indonesian Journal of Applied Research Vol 1 No 3 2020 services feel that the use of these services increases the effectiveness and efficiency of their business transactions, they will have an accepting attitude in using the e-marketplace service.
Consumers in Pusat Perbelanjaan Mentaya feel convenient and happy when using e-marketplace services because it is easier for them to make purchases, sales and find and promote their services or products.
Others, if consumers feel that e-marketplace services are not useful, then consumers will not like or reject e-marketplace services to help with their business transactions.
The results of this study support previous research by (Kurnia & Chien, 2.

The results of this study also support previous research by (Lu et al.
, 2.
, (Lou et , 2.
, and (Setiawan, 2.
which states that perceived usefulness (PU) have a significant effect on behavioral intention (BI).
On hypothesis 5 test results, the variable attitude toward using (ATU) affects the variable behavioral intention (BI) the results are declared not accepted.
This is because the attitude in using e-marketplace services does not determine user behavior in the future.
If the userAos attitude towards e-marketplace services tends to be negative, then users will certainly not use the e-marketplace service in the future and look for other alternatives to replace existing e-marketplace services.
This is in line with research (Widyapraba et al.
, 2.
which states that attitudes in the use of technology have no influence on user behavior in using this technology in the future.
This is in stark contrast to research (F.
