Abstract

Along with the development of battery/ACCU technology, the ACCU charging and loading system has also developed manually or automatically. In this paper, the results of research on the manufacture of tools that function to monitor and control the charging and loading of electrical power will be explained from batteries that are burdened with lights and DC motors through a control panel or android smart phone with IoT technology. This tool is designed to monitor 2 ACCUs, namely ACCU1 and ACCU2. ACCU1 is loaded with lamp and parallel with DC motor load while ACCU2 is loaded with DC motor and parallel with lamp load. If ACCU1 and ACCU2 are full, ACCU1 is loaded with only one lamp and ACCU2 is only loaded with DC motor. For example, ACCU1's electrical power is still within the limits that can be loaded with lights and DC motors while ACCU2 can't be loaded because electric power is not capable of being loaded with DC motors, the DC motor's load will be transferred to ACCU1. So that ACCU1 is loaded with DC lamps and motors and ACCU2 is charging the electricity, as well as for the opposite condition. The design of this tool uses the main component of the ESP32 microcontroller, where this component has been integrated with the wifi module and other supporting circuit modules, namely the current sensor circuit, voltage sensor and OLED display. The software design consists of a program code designer for hardware using C++ and an android smart phone application design using MIT App Inventor. The results of this study are in accordance with the design specifications, namely the device can be used to control charging and loading as well as monitor ACCU1 and ACCU2 electrical power on OLED screens and on Android smart phones screens

Abstract

Users of Honda motorbikes have been increasingly popular for many years, ranging from young people to adults. In general, motorbike users do not understand the damage that occurs to motorbikes and tend to hand it over to technicians without knowing whether the damage is simple or complicated to repair. With these considerations, it is necessary to make a system of tools to detect damage that occurs to motorbikes, so we need a system that can help motorbike users to overcome problems of damage that occurs to motorcycles, especially Honda Sport GL Pro, Megapro, and Tiger. A knowledge-based system for identifying motorcycle damage that is displayed using a web-based programming language. forming a decision tree and used to classify the damage into damage that most affects the motor to minor damage. Complaints are generated so that a system can be created that can help users for initial handling that occurs on motorbikes and is expected to speed up the repair of motorbikes that are classified as mild damage.

Abstract

Saat ini kWh meter konvensional masih digunakan untuk memantau konsumsi listrik di Indonesia, sehingga masih diperlukan petugas yang mengunjungi rumah pelanggan setiap bulannya. Hal ini mengakibatkan Perusahaan Listrik Negara (PLN) harus menyediakan pencatat meter yang menjadi beban biaya perusahaan. Sementara itu pencatat meter mengalami kendala ketika rumah pelanggan kosong dan tidak dapat dicatat meternya. Permasalahan ini dapat diselesaikan jika menggunakan teknologi pencatatan yang otomatis dan bisa dikendalikan dari jarak jauh. Saat ini kemajuan teknologi memungkinkan konvergensi antara saluran komunikasi dengan berbagai hal. Teknologi yang dikenal dengan Internet of Things (IoT). Penelitian ini bertujuan untuk membuat pemantauan konsumsi energi listrik berbasis Internet of Things (IoT). Alat ini akan membantu perusahaan (PLN) dalam memantau penggunaan listrik setiap pelanggan tanpa petugas pencatat meter. Prototype alat ini telah berhasil dikerjakan menggunakan PZEM-004T yang kemudian mampu menampilkan tegangan, arus daya, power factor dan waktu. Luaran dari alat kwH meter teknologi IoT ini kemudian dikirimkan ke basis data Firebase. Firebase memiliki keunggulan karena ditempatkan dalam cloud. Sehingga data yang diperoleh dapat juga ditampilkan dalam aplikasi android. Hasil pengujian dari prototype kemudian dilakukan pengujian beban dan dibandingkan dengan alat ukur sejenis yang ada di pasaran. Pengujian beban menghasilkan keakuratan sistem dengan rata-rata persentase akurasi tegangan: 99.25%, arus: 99.82%, daya: 97.50% dan factor daya: 98.78%. Penelitian ini menghasilkan prototipe menggunakan ESP32 dan PZEM-004T yang sangat akurat sehingga dapat direkomendasikan untuk pencatatan daya listrik yang mampu mengurangi beban biaya operasional PLN.

Abstract

The increasing complexity of modern processors and rapid advances in computing technology pose significant challenges for users seeking to select the optimal processor to satisfy their specific requirements. The " Processor Selection with AHP-Profile Matching: Implementation and Performance Analysis" addresses this problem by providing a structured, evidence-based approach to processor selection. This system integrates the Analytic Hierarchy Process (AHP) and profile matching algorithms to evaluate and rank processors based on parameters such as brand, price, socket type, thermal design power (TDP), core count, thread count, clock speed (GHz), DDR compatibility, and PCIe version. User inputs were collected and analyzed using the AHP to determine the relative importance of each criterion. Profile matching aligns user requirements with optimal processor configurations in a database. Results are presented through a comparative analysis that highlights each processor's strengths and limitations. Compatibility checks ensure seamless integration with existing hardware. The results indicate an accuracy of 81% with AHP alone and 91% with the combined AHP-Profile Matching approach. The proposed system significantly improves decision-making efficiency by providing a robust, user-centric processor selection approach and optimizing computational performance.

Abstract

The rejection on ratification of the revision of Indonesian Code Law or known as RKUHP and Corruption Law raises several opinions from various perspectives in social media. Twitter as one of many platforms affected, has more than 19.5 million users in Indonesia. Twitter is one of many social media in Indonesia where people can share their views, arguments, information, and opinions from all points of view. Since Twitter has a great diversity of users, it needs a system which is designed to determine the opinion tendency towards the problems or objects. The purpose of this study is to analyze the sentiment of Twitter users' tweets to reject the revision of the Law whether they have positive or negative sentiments using the Agglomerative Hierarchical Clustering method. The data that being used in this study were obtained from the results of crawling tweets based on hashtag (#) (#ReformasiDikorupsi). The next stage is pre-processing which consists of case folding, tokenizing, cleansing, sanitizing, and stemming. The extraction features Lexicon Based and Term Frequency (TF) which performs the process automatically. In the clustering stage, two clusters use three approaches; single linkage, complete linkage and average linkage. In the accuracy calculation phase, the writer uses the error ratio, confusion matrix, and silhouette coefficient. Therefore, the results are quite good. From 2408 tweets, the highest accuracy results are 61.6%.
