Abstract

Perkembangan teknologi otomotif salah satunya ditandai dengan semakin beragamnya produk kendaraan yang ada di pasaran. Perkembangan ini juga mengarah pada penyempurnaan desain bentuk mobil yang lebih aerodinamis untuk mengurangi gaya gesek udara yang dapat mengurangi konsumsi bahan bakar. Penelitian dilakukan untuk menguji gaya drag dan pengaruh kecepatan angin. Pengujian dilakukan dengan mengukur simpangan drag pada terowongan angin terhadap 4 model yaitu VW Classical Bus, VW Classical Beetle, VW New Beetle dan VW Lupo serta 5 variasi kecepatan dengan 5 kali ulangan untuk setiap variasi pengujian. Hasil pengukuran ini dipakai untuk menghitung gaya drag yang selanjutnya dilakukan uji statistik. Kesimpulan yang didapat dari penelitian ini adalah VW Classical Bus memiliki gaya drag tertinggi diikuti VW, New Beetle, VW Lupo dan VW Classical Beetle dan ada pengaruh kecepatan angin terhadap gaya drag jika diinteraksikan dengan model.   Kata kunci : Model mobil, Kecepatan angin, wind tunnel, aerodinamis dan gaya drag

Abstract

Tingkat pemakaian kendaraan bermotor semakin tahun semakin bertambah  dan akan menyebabkan  tingginya konsumsi bahan bakar dan kadar polusi. Dengan kinerja mesin yang optimal dan pembakaran yang sempurna pada kendaraan bermotor dapat dikendalikan. Proses pembakaran bahan bakar di dalam silinder dipengaruhi oleh: temperatur, kerapatan campuran, komposisi, dan turbulensi yang ada pada campuran. Apabila temperatur campuran bahan bakar dengan udara naik, maka semakin mudah campuran bahan bakar dengan udara tersebut untuk terbakar.Tujuan penelitian ini adalah untuk mengetahui pengaruh pemanasan bahan bakar dengan media radiator terhadap konsumsi bahan bakar supaya lebih hemat dan  meningkat kinerja mesin (daya mesin). Kata Kunci : Radiator, Pemanasan, bahan bakar, kinerja mesin.

Abstract

Elektro kardiogram umumnya dipresentasikan dalam amplitude basis waktu. Dalam basis frekuensi, suatu sinyal akan dipresentasikan dalam magnitude terhadap frekuensinya, sehingga terlihat fekuensi – frekuensi penyusunnya. Penelitian ini bertujuan untuk merepresentasikan Elektro kardiogram basis spasial kondisi Normal dan Abnormal kedalam spectrum frekuensi menggunakan Program Excel. Metode sampling digunakan untuk mengubah sinyal analog kontinyu menjadi sinyal diskrit. Penerapan metode Fast Fourier Transform pada data diskrit akan diperoleh magnitude berbasis frekuensi yang dikenal dengan spectrum frekuensi. Lead II merupakan acuan parameter bagi lead-lead yang lain karena memiliki morfologi yang jelas untuk amplitude PQRST. Dalam penelitian ini, data diskrit ECG diperoleh dari Physionet MIT-BIH dan Laboratorium CVCU RS Saiful Anwar Malang. Hasil penelitian menunjukkan bahwa pada rentang frekuensi 0-40 Hz memiliki spectrum frekuensi yang tinggi untuk kondisi normal sedangkan untuk kondisi abnormal spektrumnya rendah. Pada frekuensi 0-0.05 Hz Phasenya menurun untuk kondisi normal sedangkan kondisi abnormal phasenya menaik.

Abstract

This research examines business model innovation (BMI), which has recently received attention from academics and practitioners due to the enhancement of global competition and the constant need to adapt to the changing environment. Therefore, the main objective of this study is to provide an overview of state-of-the-art research on business model innovation by conducting a systematic literature review. The author's review provides a deeper understanding and detail on the main components of Business Model Innovation (BMI). Likewise, the author's research identifies the role of digitalization in Business Model Innovation. This study comprises a comprehensive literature evaluation with a particular focus on studies linked to the use of digital technologies and business models to understand better attempts to promote the usage of digital systems. This study aims to promote the academic conversation about how industrial companies might use digital technologies to innovate business models and create a sustainable industry. Implementing new business models that promote the implementation of digital systems necessitates an essential shift of the corporate ecosystem into one in which appreciation is jointly generated by suppliers, environment partners, and consumers through resource optimization and efficient functioning and use of technology.

Abstract

The development of the industrial world which is increasingly developing at this time will lead to high competition in the industrial world. So that the profits of each company also have an influence. New ideas are urgently needed to bring the business world in a more advanced direction so that it can keep up with increasingly fierce competition. Terang Alam Semesta is one of the MSMEs that operates in the Bag Manufacturing Sector. In this research, the Linear programming method is used as an operational research model in applied mathematics studies which is widely used in industry and business organizations and can be used in the process of obtaining solutions and solving production problems. From the results of research using POM for Windows software, it was found that Terang Alam Semesta would gain maximum profits if it could produce 15 Premium Leather Bags and 10 Semi-Leather Bags with a profit of IDR. 900,000 per day.

Abstract

In today’s era of advanced globalization, competition in the business landscape is becoming increasingly intense, particularly within the fashion industry, including the batik sector. As a symbol of Indonesia’s rich cultural heritage, batik has evolved significantly, gaining popularity not only in domestic markets but also on an international scale. Once regarded solely as traditional attire, batik is now embraced as part of contemporary fashion that appeals to a wide range of consumers. Batik Malabis, a local batik business based in Bangkalan, Madura, is one of the enterprises that has actively adapted to these changing trends. By integrating traditional Madurese patterns with modern design elements, Batik Malabis seeks to engage a broader customer base—especially younger generations who are beginning to view batik not only as a cultural expression but also as a stylish and fashionable choice. This research adopts a qualitative method using a case study approach to explore the marketing strategies employed by Batik Malabis in boosting the sales of its modern batik products. This approach enables a thorough investigation into various aspects of marketing, including promotional tactics, pricing strategies, and the use of digital platforms tailored to the preferences and behaviors of the target market. Data were gathered through literature review from diverse sources such as scholarly journals, academic books, and industry publications related to marketing in the fashion and batik sectors. This provides a well-rounded understanding of the effectiveness of the marketing efforts implemented by the business. The purpose of this study is to examine how Batik Malabis applies marketing strategies to enhance product sales. Furthermore, the research aims to identify the strengths and weaknesses of these strategies, offering practical and relevant recommendations to support Batik Malabis in remaining competitive in a dynamic and increasingly challenging marketplace.
