This study aims to describe the design of rural public wireless internet development based on a supply chain structure approach. Now, many new internet services have sprung up in the private, public, business, education, health, and even governmental sectors until considered as the leading global system. Especially in rural areas, the provision of cable internet networks and cellular internet networks have not been able to reach all rural areas, so a new breakthrough is needed, one of which is a public wireless internet network. This research was conducted with a Design-Based Research approach that combines scientific design methods with the problems that occur for internet development in rural areas of Indonesia. The finding that the development of wireless internet in rural areas can be carried out with the concept of a supply chain structure consisting of suppliers (ISP providers of internet sources), manufacturers (local government or village-owned enterprises managing and transmitting wireless internet to wholesaler), wholesaler (installed 5GHz wireless repeater in people residential areas), retailers (installed 5GHz wireless receiver devices from wholesaler and convert to 2.4GHz wireless transmitters installed in every resident’s house) and customers (each resident’s smartphones or notebooks device connected by wireless).

The Payment System is a series of interconnected components consisting of rules, institutions, and procedures used for money transactions in fulfilling the obligations of economic activities. The Duta Bangsa University of Surakarta is a case study in this research where the student payment system is still a billing system. The faculty finance department gives bills tuition fees to students one by one. Moreover, it determines the bank used for payments. It resulted in quite many queues when filling out the study plan card (KRS) and exams. This research aims to produce a web service application and standardization with good performance in the payment process at Duta Bangsa University through virtual accounts from various banks and payment channels. The method used to achieve the authors' goals in this study is the Rational Unified Process (RUP) method. The research result is a web service application that can make invoices, inquiries, payments, and reversals of various bank payment channels. The User Acceptance Test results show a very agreeable value of 94.17%, so that the web service is feasible for the production version application. While testing the response time to measure performance for 7 (seven) days, the average response time was 0.49809 seconds.

There are many forms of advertising on the internet. An agreement between the advertisers and advertisers typically includes the types of ads and host sites that will show their ads Just like Pop-up ads are displayed in a variety of shapes and sizes, typically on a scale that scaled down the browser window with just the "Close", "Minimize", and "Maximize" commands.

This research is a study of socio legal which is a study of law by using approach of law and social sciences [1]. Research Sites in Indonesia. Primary data obtained from interviews with internet users using judgement sampling and secondary data were obtained from literature. Primary legal material is Law No. 8 of 1999 on Consumer Protection and Law Number 11 Year 2008 on Information and Electronic Transactions. Data collection techniques use observation, interview and literature. The sampling technique used is Judgment sampling [2] Data Analysis Technique used qualitative descriptive analysis. Research finding that there is a prohibition for advertising business actors to produce ads that violate ethics (Article 17 letter f of Law Number 8 Year 1999 on Consumer Protection).
