Security is an important aspect that must be considered from a house, building, and environment. The purpose is to avoid various types of crime such as theft and robbery that can cause loss. In various regions in Indonesia, the rate of theft and robbery is still high, so a good security system is needed so that cases of theft and robbery can be avoided as early as possible. In the era of technology that is developing so rapidly nowadays, there are many breakthroughs in security systems for homes, buildings, and environments that utilize technology, one of which is a security system based on IoT (Internet of Things). In this paper will focus on reviewing the concepts applied by several previous papers relating to security systems for homes, buildings and the environment. Then the results of the review can obtain appropriate and relevant concepts to be applied for home security systems with minimal internet network conditions.

Information technology is not just a bridge for delivering information but has become part of a strategy to achieve the organization's vision and mission. ABC Health Center is a government organization that functions as a provider of firstlevel public health facilities. ABC Health Center so far still relies on Microsoft office data processing information technology and some data still uses paper. This creates several problems such as vulnerability to damage, loss and duplication of data or documents. Seeing these problems requires an integrated information technology so that health services can be more effective, efficient, fast, and relevant. To produce a good information technology, it is necessary to design an information technology architecture that refers to a framework. In this study the TOGAF ADM (Architecture Development Method) framework has been proposed as a reference for architectural design. Where TOGAF ADM itself provides details on how to determine an enterprise architecture based on the organization's main needs. The output generated from this framework is a blue print that is used as a reference for ABC Community Workforce to develop information system technology. Thus, each business process contained in the ABC Health Center can answer all the vision and mission to be achieved.

Collecting the Tourism Contextual Information data to support the tourism recommendation system

Clean water is an essential basic requirement for humans. In eastern Indonesia, especially the provinces of East Nusa Tenggara (NTT), Maluku and Southeast Sulawesi, the need for clean water is quite urgent. The socio-cultural conditions, geographical conditions, low rainfall levels, and the distribution of freshwater from the Regional Water Company (PDAM) is still not right. Communities in the three provinces utilise clean water buying and selling services using tank cars to fulfil their daily needs for clean water in reservoirs and water tanks. Orders still use telephone or SMS, so it seems slower. Thus the design of mobile ordering applications for clean water was proposed in this study and was named Go-Water. With the Go-Water app, users can order clean water by choosing the closest shelter model and driver, and then the order is forwarded to the driver for processing. The User-Centered Design (UCD) method use for Go-Water application design. The Go-Water application can help users to order clean water quickly and help improve business quality for service providers. The results of the usability perspective analysis on the Go-Water application design obtained an average percentage of 83%. The result shows the design of the Go-Water app, can be accepted according to user needs. The contribution in this study is the design of the proposed mobile application centred on the user, previously there was no system for ordering 5,000 litres and 6,000 litres of clean water using a tank car and the price offered was more beneficial for both parties.
