E-commerce has become a fairly developed concept in the field of technology today. In addition to providing convenience and advantages compared to conventional shopping concepts, including all the desired information, consumers can be accessed in more detail, quickly without being limited by place and time, and the transaction process can be done more easily. Competition among competitors in the field of e-commerce has been overwhelming and competing with each other in innovation to be superior in the market. This study will conduct a quality test of one e-commerce company using the WebQual method. In its implementation with this method to measure quality on a website based on the observation of the questionnaire to the user as a source of data. The results of this study will conclude a number of factors that are very important to customer satisfaction to be evaluation advice for the company.

In preparing to welcome the era of technology 4.0, especially preparing rural communities to be ready to accept the arrival of the era of technology 4.0, how can rural communities utilize the technology for their interests. Especially how rural communities can promote superior products produced by the community in general as well as rural communities in particular by using these technologies. In this research, it will be discussed how the application of E-Business can help marketing superior village products, and based on the mandate of law number 6 of 2014 "About the Village", article 86 "Information Systems for Rural Development and Rural Area Development". The problems faced, among others, are many villages that have not been touched by information technology, many villages that have superior products have not been touched by information technology, the potential, and superior products of the village are not fully promoted so that the potential and village products are not widely known. The purpose of the research is to provide the best solution so that the existing problems can be resolved, of course by utilizing information technology, which is a web-based application, by incorporating the concept of E-Business in the application to be made. The results of this study are the application of B2B and B2G E-Business to support the creation of E-Marketing Applications that can be used as solutions to problems that occur.

To uncover the insight behind the data, a comprehensive analysis is needed. Exploratory Data Analysis (EDA) is one of practical data analysis that will guide how to reveal any hidden information in the data. By doing EDA, any pattern and issue in the data will be seen and eventually will lead the hypothesis. To do EDA, besides any basic statistic is needed, a good tool to simplify the analysis is also a consideration. Python and R as a famous programming language in the data science world provide methods to implement that analysis. This paper will show how to perform EDA by utilizing Python and R programming.

The village has an important role in improving the national economy. A developed village will have a good impact on people's lives, both from the economy and the welfare of the community. The village head has an important role in running the government in rural areas. One of the indicators for evaluating the success rate of development and prosperity of an area is the success of a village itself so that the village or village has an important role in the process of improving development. With special autonomy regarding village development, the role of the village head becomes central and becomes the driving force for village development. To find out how well the village head is performing, it is necessary to have a breakthrough in measuring the village head's performance index in Pringsewu Regency. In measuring the performance of the Village Head, the criteria and weighting of the Simple Additive Weighting and TOPSIS methods are used. The sample was tested using eighteen villages spread across nine sub regency in the Pringsewu Regency. The application of two methods of decision support systems using Simple Additive Weighting and TOPSIS in measuring the index of Village Heads in Pringsewu Regency can trigger an increase in the performance of village heads to build the villages based on predetermined criteria. Of the eighteen alternatives tested, the highest value was A16 with a value of 0.8901508.

The aim of this work is to study the existence, uniqueness and stability of periodic solutions of some classes for non-linear systems of new Volterra integral equations with singular kernel in two variables by using Riemann integrals. Furthermore, we investigation the existence, uniqueness and stability of the fundamental tools employed in the analysis are based on applications by depending on the numerical-analytic method for studying the periodic solutions of ordinary differential equations which were introduced by Samoilenko.The study of such nonlinear Volterra integral equations with singular kernel leads us to improve and extend Samoilenko method. Thus the non-linear integral equations with singular kernel that we have introduced in the study become more general and detailed than those introduced by Butris .

The greater growth of electricity consumption, especially for high voltage consumers, it is important for PLN to know the effect of the current transformer (CT) error ratio in the accuracy of the kwh of electricity transactions, by researching the error ratio of CT 400/1 and 800/1 R, S, and T phase. When the contracted power of 120 MVA can be used CT class 0.2s ratio 400/1 and 800/1 ratio, when using CT class 0.2s ratio 400/1 then the kwh meter can be set according to the CT ratio that is the ratio 400/1 because CT ratio 400/1 has a negative error ratio at loads below 73.59%, and positive error ratio at loads over 73.59% up to 100% load, and` when using CT class 0.2s ratio 800/1 then the kwh meter can set a CT ratio of 800 / 0.98 because CT ratio 800/1 has a positive error ratio of 0.02% from 1% load to 100% load, so that it does not harm the customer as a positive CT ratio error tolerance . This needs to be done in order to create justice between PLN and high voltage consumers in the calculation of kwh transactions.The greater growth of electricity consumption, especially for high voltage consumers, it is important for PLN to know the effect of the current transformer (CT) error ratio in the accuracy of the kwh of electricity transactions, by researching the error ratio of CT 400/1 and 800/1 R, S, and T phase.

The country of Indonesia is a developing country. This is indicated by the improvement of the development process and business. So, many development projects will appear. With the changing world in the industry with e-Government governance, project data is no longer in paper form. With the emergence of data - a lot of companies need to do project management activities in determining the project strategy to be taken so as not to affect the final results in determining the taking of the project. Then do a lot of research on the project data that appears in the construction world. The method used for this research is the C4.5 Algorithm which is one of the modern algorithms for data mining processes. C4.5 algorithm is also called a decision tree (decision tree) which is one of the classification methods with a tree structure representation. The concept is to collect data and be made into a decision tree based on the rules needed to get an outcome. The pattern and results obtained will be used for recommendations in determining which projects the company will take. The values generated using Rapidminer are Accuracy 97.18%, precision 100%, and recall 94.31%. With the result, 1205 recommended floor construction projects were taken and 784 projects were recommended not to be taken.
