Desain dan Implementasi Pemotong dan Pengupas Kabel Otomatis Berbasis Arduino
No full textIn the field of audio and light automotive system assembly, the cable cutting and stripping process is a crucial stage that requires a high level of precision to ensure the quality of the connection and neatness of the installation. The use of manual methods often takes longer and has the risk of mismatching the cutting and stripping sizes of the cable. Therefore, this research aims to design and develop an automatic cable cutting and stripping tool based on the Arduino Uno microcontroller equipped with a Nextion LCD touchscreen interface. This system is specifically designed to process NYAF (Nylon Awg Flexible) type cables with diameters of 0.5 mm, 0.75 mm, and 0.85 mm, which are commonly used in audio systems and light automotive electrical installations. This tool uses two NEMA 17 stepper motors controlled by the DRV8825 driver to precisely pull and control the movement of the cable, as well as a servo motor to operate the guillotine-type cutting mechanism. Stripping of the cable insulation is carried out using a V-shaped knife to produce uniform and neat stripping results. Using the Nextion LCD interface, users can adjust the cable length and stripping length as needed, which is then automatically processed by the Arduino Uno. This tool is expected to improve work efficiency, cutting and stripping accuracy, and cable installation neatness in the assembly of audio and light automotive systems

Penggunaan Kalimat Efektif Dalam Pidato Inspektur Upacara Bendera Sebagai Bahan Ajar Untuk Tingkat SMP
Get PDFSentences are the smallest units at the language level. Sentences in language express complete thoughts or ideas. These complete thoughts and ideas can be communicated verbally or in writing. In the form of speech, sentences are marked by intonation in the form of high and low speech, pauses, and ending with a sign of completion. Sentences in written form are marked with spelling and end with appropriate punctuation. Speech certainly requires skills in using language as a communication tool so that information can be conveyed properly and correctly. A sentence is said to be effective if it succeeds in conveying a message, idea, feeling or notification according to what the speaker or writer intended. The application of effective sentences in speech represents a challenge for communicators to be able to package the meaning conveyed adequately and be accepted by the listener. However, there are many phenomena of misunderstanding or information that is not conveyed correctly during a speech due to unclear speech or words that the listener does not understand. In using existing theories, it needs to be scientifically proven to determine the effectiveness of the sentences used in the speech. Departing from these various opinions is the basis for the author's consideration of the need to study the use of effective Indonesian sentences in the address of the flag ceremony inspector at Junior High Schools (SMP) in Colomadu District, Karanganyar Regency, Central Java. By using deep qualitative descriptive research methods audiotape which has been transferred into text form.
