This paper presents a coffee aroma detection system based on the Internet of Things (IoT) using gas sensors (MQ-3, MQ-4, MQ-5, MQ-135) and a DHT-11 humidity sensor. Data collection was conducted at the Robotics, Control, and Embedded Systems Laboratory, Faculty of Computer Science, Sriwijaya University, involving coffee aroma, temperature, and humidity readings. The gas sensors provided reading…
Pinch analysis is a method for minimize the consumtion energy of Chemical process to compnte feasible target energy• termodynamic (minimum consumtion energy) and achive it with optimize heat recovery system, supply energy method and process operation condition It’s call integration process, heat integral ion, energy integration or pinch teenology. Comparison with manual analysis, we need te…

This research reports the result about enhancement dielectric strength of kraft paper impregnated with oil blend of diala B oil and corn oil with filler Al2O3 with a concentration of 0.5 wt%. The kraft paper sample used is in the form of a sheet with a thickness of 0.04 mm and a size of 30 mm x 30 mm. The kraft paper samples impregnated with a mixture of diala B oil and corn oil with or without…
Convolutional Neural Network (CNN) is a part of deep learning commonly used for image classification. There are many studies that utilize CNN for classifying tuberculosis and covid-19, as well as normal conditions, using chest x-ray images. However, these studies are still rarely implemented on Indonesian data. Furthermore, the CNN models built have not been deployed in the form of a user inter…
The tendency of people to use private vehicles compared to using public transportation can cause congestion in the city of Palembang. Therefore, it is necessary to visualize spatially in order to be able to know the selection of modes used to head to the location of origin and the availability of public transport infrastructure in the city of Palembang, so that public transport services can be …
Most CCTV systems are typically used for monitoring individuals captured on camera within a specific area under surveillance. In this study, we have developed an interface for CCTV monitoring using deep learning models. The interface is built using Flask as a framework to create a website-based platform. The system of this interface displays the streaming feed from CCTV cameras connected via RT…
In IC-Flash lightning itself there is a special type which is generally called Narrow Bipolar Pulses (NBP) or Narrow Bipolar Events (NBE). These lightning flashes also often initiate CG flash lightning flashes. NBE consists of two types, namely positive polarity (PNBE) and negative polarity (NNBE). Based on previous research, there were 12908 lightning recording data, but only 2545 data could b…
In developing applications, a good database is needed to store data from an application. Data availability and security must be guaranteed by the database developer. Users also need to know what their data is used for by the application. Blockchain provides all the previous features, starting from decentralized, which means the application runs user-to-user, which means that ongoing activities …
With the increasing human population cause a lot of usage the products made of plastic. Among to reduce the accumulation of plastic waste is by recycling plastic waste properly, one of which is by doing the sorting stage. This study aims to create a system of identification and classification of plastic bottles based on the type. The Random Forest method is used to simplify the process of sorti…
A lightning location system (LLS) is designed to determine the location or estimate of a lightning strike more accurately. It is essential to map areas with high intensity of lightning strikes so that they can be used as a reference in determining protection for specific objects and minimizing losses to both inanimate objects and living things. In this project, the data used is secondary data o…
