<p><em>The presence of a local software house company is a solution choice for companies on a small, medium and large scale. The software house company has been able to provide solutions to fulfill information systems and produce good quality software products. However, local software house companies face operational problems with the company's internal information technology in completing projects obtained from their customers. To solve the company's internal information technology problems, the company applies the enterprise architecture method to streamline the company's operations. So far, information technology operations in software house companies have experienced ineffective operations with various application systems that have been implemented. Changes in information technology operations by rearranging using the Enterprise Architecture method, and applying it to the company's software house. This study aims to develop Enterprise Architecture in a software house company, where all are designed using Information Technology Planning based on the TOGAF-based Enterprise Architecture Framework. With the application of Enterprise Architecture, information technology operations can be changed to be more organized and more efficient in supporting company operations.</em></p><p><strong><em>Keyword:</em></strong> <em>Software House; Enterprise Architecture; TOGAF; Information System</em><strong></strong></p><p align="center"><strong> </strong></p><p><strong>Abstrak</strong>. Hadirnya perusahaan <em>software house</em> lokal menjadi pilihan solusi bagi perusahaan dalam skala kecil, skala medium dan skala besar. Perusahaan <em>software house</em> telah mampu memberikan solusi pemenuhan sistem informasi dan menghasilkan produk <em>software</em> yang berkualitas baik. Namun perusahaan <em>software house</em> lokal menghadapi permasalahan operasional informasi teknologi internal perusahaan dalam menyelesaikan proyek yang didapat dari pelanggannya. Untuk menyelesaikan permasalahan informasi teknologi internal perusahaan, perusahaan menerapkan metode <em>enterprise</em> arsitektur dalam mengefektifkan operasionalnya. Selama ini operasional teknologi informasi di perusahaan <em>software house</em> mengalami operasional yang tidak efektif dengan berbagai sistem aplikasi yang telah diterapkan. Perubahan operasional teknologi informasi dengan menata ulang menggunakan metode <em>Enterprise Architecture</em>, dan menerapkannya ke dalam perusahaan <em>software house</em>. Penelitian ini bertujuan untuk mengembangkan <em>Enterprise Architecture</em> pada perusahaan <em>software house</em>, dimana semua dirancang dengan menggunakan <em>Information Technology Planning</em> dengan <em>Framework Enterprise Architeture</em> berbasis TOGAF. Dengan penerapan <em>Enterprise Architecture</em> dapat mengubah operasional informasi teknologi menjadi lebih tertata dan lebih efisien dalam mendukung operasional perusahaan.</p><p><strong>Kata kunci</strong><strong>:</strong><em> Software House; Enterprise Architecture; TOGAF; Sistem Informasi</em></p>

Freshwater fish farming is currently booming in Indonesia, and many use small ponds for efficiency or due to limited location, this can be a problem due to Indonesia's hot climate. Small ponds with not much water volume will cause the water temperature to rise more easily on hot days, of course this is not good for the fish colonies in it. To prevent temperature rise, farmers generally irrigate ponds with fresh water to stabilize the water temperature. Due to the unpredictable weather in Indonesia lately, it will be difficult for farmers to monitor their ponds manually, so a tool is needed that can detect the heat of pond water and turn on the water pump to irrigate ponds. This research is expected to make it easier for farmers to regulate pond temperatures more easily. The use of a microcontroller in Internet of Thing devices is very much needed, considering that the microcontroller is able to carry out the task of controlling the existing sensors. The sensor used in this study uses a temperature sensor that is used to control the pool water. The prototype for detecting pool water temperature and increasing water flow is used to reduce heat in pool water and increase water flow that is reduced due to evaporation of water during the day. The purpose of this research is to make a prototype to detect pond water temperature and increase pond water discharge which is useful for reducing pond water temperature to be cooler and reducing the risk of fish death. The prototype developed is a NodeMCU ESP 8266 micro-controller, a temperature detection sensor in water, a relay as a switch and a mini pump
