In Indonesia, the mortality rate for pregnant women is still high. One of the contributing factors is the lack of knowledge and awareness of communication between pregnant women and midwives in the process of antenatal care, resulting in a delay in recognizing the danger signs of pregnancy. The purpose of this study is to provide a pregnant mother's health application that can be run on an android system. Android as a smartphone operating system, supports the development of new application ideas and innovations to add system functionality. The stages of making the application include (1) analyzing user needs by observing the Independent Practice Midwife in the Polokarto Sukoharo area, Central Java. Next, (2) design a system consisting of two users, including midwives and pregnant women. Finally, (3) the implementation of making a system design in the form of an android application. This Maternal Health Application has a feature that pregnant women can communicate with midwives directly to submit complaints, examination results, information about pregnancy and the calculation of Estimated Birth Days (HPL). Thus, it is hoped that this application can be used as a digital health service that facilitates access to information and public health services, especially those related to pregnancy.

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).
