Abstract

Customer problems are indeed very complex, therefore they must be handled properly, clearly, and thoroughly. Good service from a company can show the professionalism of the company itself, meaning that seriousness, certainty of time, punctuality and work results that can be accounted for in solving all problems can prove the quality of a company. Clustering is the process of partitioning a set of data objects into subsets called clusters. Objects in the cluster have similar characteristics to each other and are different from other clusters. Clustering is very useful and can find unknown groups or groups in the data. From 2056 customer complaint data, the results obtained are Cluster 1, namely 12, 5, 5, in cluster 2, namely 4, 5, 5 and cluster 3, namely 8, 2, 2. With the number of cluster members 1 883 members, cluster 2 635 members and cluster 3 namely 538 members. From the results of the Matlab cluster, there are similar results, namely the types of complaints in cluster 1 and cluster 2, namely code 5 types of leaking pipe complaints with handling damage to connecting water pipes (gibout join). Keywords : Clustering, Custome Problems, Matlab

Abstract

The IoT-based LPG gas leak detection system with MQ-2 and automatic regulator aperture is designed to protect the environment from the dangers of gas leaks and optimize gas use. The MQ-2 sensor is used to detect LPG gas accurately and sensitively. This system is connected to IoT which allows remote monitoring via smart devices. When the sensor detects that the LPG gas concentration exceeds a safe threshold, the system will send an alert with notification and automatically activate the regulator to cut off the gas supply. This helps prevent the accumulation of harmful gases. This design combines reliable gas detection with automatic operation to improve environmental safety and gas efficiency. LPG gas is very commonly used by the community because it has many advantages, but there are also many risks associated with using LPG gas, such as poisoning, shortness of breath and even fire. It is therefore important to have a leak detection system to prevent accidents that may occur, by integrating the programmable MQ-2 sensor and NoteMCU ESP8266.

Abstract

Book is a window to the world. By reading books, we can get a variety of knowledge that we do not know. The meaning of books as windows to the world can be doubted today. Given the internet provides a lot of information with a much more attractive appearance. Both books and the internet provide a wealth of information and knowledge. But in fact books are still the mainstay of accurate sources of knowledge. A lot of information on the internet is in fact not supported with accuracy. Even in the world of higher education, books are the main reference source in scientific writing. However, old books that may have started to become dull and the writing can no longer be read resulted in the reader of the book not being able to know the knowledge contained in the old book. Based on observations, it is necessary to build a computerized system so that the writings in the book can be read again. One method that can be used is the Thresholding method. The system is designed with MATLAB programming application. In this process, it is necessary to scan or take photos/pictures from cellphone cameras from old book manuscripts to be processed on the system using the Thresholding method. After carrying out the testing process on several images of old books, better results were obtained so that the writing on the manuscript could be seen more clearly with different threshold values for each image entered into the system.
