Abstract

Sustainable Tourism Research, Tourism 4.0, digital-based tourism to improve the welfare of people in East Java, is part of the Global Sustainable Cities, Sustainable Development Goals (SDGs) master plan, the Sustainable Development Goals (TPB), which are the global development agenda of countries in the world. Goal 11: Sustainable Cities and Settlements, Green cities as cities that are designed to consider environmental impacts, are inhabited by people who have an awareness of conserving energy, water and food use and minimizing waste disposal, water pollution and air pollution. Sustainable Tourism, not only the concept of conventional tourism, but tourism that considers environmental impacts, inhabited by the community has an awareness of conserving energy, water and food use and minimizing waste disposal, water pollution and air pollution. In 2030, more than 60% of Indonesia's population are residents who live in urban areas, so Sustainable Tourism is a very important need to implement. The aim of the research is to create a sustainable tourism design and model, not only the concept of conventional tourism, but tourism that considers environmental impacts, inhabited by people who have an awareness of conserving energy, water and food use and minimizing waste disposal, water pollution and air pollution, based on digital technology. Research methods, secondary data collection, data analysis, continued with the preparation of digital data and the preparation of geographic information technology 4.0 in the form of web GIS and mobile GIS (Android / iOS). A Geographic Information System (GIS) is a special information system that manages data that has spatial (spatial reference) information. Or in a more narrow sense, is a computer system that has the ability to build, store, manage and display geographically efficient information, for example data identified by location, in a database. In general, the notion of a Geographical Information System is a component consisting of hardware, software, geographic data and human resources that work together effectively to enter, store, repair, update, manage, manipulate, integrate, analyze and display data in information. geographically based. (Prahasta, Eddy, 2003 in Masudara, Jenry J, 2015). According to Pressman (Pressman, 2010 in Masudara, Jenry J, 2015), the waterfall model is a classic model that is systematic, sequential in building software. The name of this model is actually "Linear Sequential Model". This model is often referred to as the “classic life cycle” or waterfall model. The following is an explanation of the steps in the Waterfall model: (1) Communication; This step is an analysis of system requirements. Data collection in this stage can be carried out by conducting a research, interview or literature study; (2) Planning; This stage will produce a schedule or plan that will be carried out in the research; (3) Modeling; The design process will translate the requirements into a software design that can be estimated before coding; (4) Construction; Construction is the stage of making code or coding. Coding is the translation of design or modeling in a language that can be recognized by computers. After the coding is complete, testing will be carried out on the system that has been created. The purpose of testing is to find errors in the system and then fix them; (5) Delivery of the system to customers / users; This stage can be said to be final in making a system. After analyzing, designing and coding the finished system will be used by the user
