Abstract

The enjoyment of brewed coffee is determined by many things, one of which is choosing quality coffee beans and coffee powder. Quality coffee beans are determined by shape and size (full, half full, or damaged). Checking the size and shape of coffee beans manually is subject to external influences such as fatigue, environment, light, etc. With the help of technologyimage processing, these factors can be overcome. Through this paper a tool is designed to detect coffee defects using the Yolo algorithm. The designed system consists of a camera that captures images of coffee beans which are then processed by the Raspberry Pi and the results are displayed on the laptop screen. Detection results using the YOLO algorithm for 10 trials using 100 coffee beans get an average percentage value of 76.54% for the perfect coffee bean category of 43 coffee beans, then the average percentage of imperfect coffee beans is 73.40% with lots of 48 3 coffee beans and coffee beans were not detected with an average percentage value of 1% and coffee beans included in the two categories were 6 coffee beans with an average percentage value of 19.8%. In this study the YOLO algorithm can maintain an accuracy rate of detection success of 75%.

Abstract

Bireuen Regency is an area that has historical buildings from the Dutch colonial era, one of which is the Bireuen Pendopo. It is a cultural heritage building that is more than 70 years old based on the photo archive of Ir. Sukarno with the Bireuen fighter in 1948 and was certified as "The President Sukarno Heritage List". The building has undergone changes, seen from the period of pre-independence (1934–1944), the period of independence (1945–1999), and the period after the area expansion (1999–2021). Pendopo is a cultural heritage building. A study of its physical changes is urgently needed so that the original shape does not change and the material is not entirely replaced. The purpose of this study is to identify the physical changes in the Bireun Pendopo building. The research method used is descriptive qualitative. The physical elements are categorized into minor transformation, major transformation, and full transformation. The study's results found that the Bireun Pendopo building in the pre-independence period (1934-1944) did not have any changes in its physical form. While during the independence period (1945-1998), it underwent a minor physical transformation. In the period after the expansion of Bireun Regency (1999-2020), it underwent a minor physical transformation, a major transformation, and a full transformation. The results of the study that identified the physical changes of the Bireun Pendopo based on three periods showed that most of the changes were carried out in the post-expansion period with major and full transformation categories.

Abstract

Rapid population growth has both a positive and a negative impact, such as an increase in household waste generation. This also becomes a new chain of problems in other aspects, such as health, flood, air pollution, and environmental pollution. To overcome this problem, an integrated waste management system is needed. Household waste, especially inorganic waste, was valuable. The application was developed to promote a new paradigm; waste is a new source of money. As well as help run a circular economy in the waste recycling industry. The application to be built is "WasteApp", an independent household waste management application that can track and help manage it. This application is built using the Android operating system to make it a user-friendly tool. An application trial was conducted in Geulanggang Baro village, Bireuen district involving the operator, local government, and community. This location was chosen because they already have informal waste management, and it is easier to maximize by information technology intervention. The final result of this research is the “WasteApp” application based on android to manage household waste independently. The community, operator, and local government can work waste independently and systematically through this system. This application contains several menus, including the Home menu, login, register, and the main menu, namely the waste sell history and selling waste, as well as educational articles that contain how to manage waste, from sorting waste to the recycling process. Community participation was needed to increase to full implementation of good waste management.
