Abstract

This research was conducted at PT Tri Sapta Jaya, a medical equipment distributor company. The product distribution to consumers was inefficient due to using traditional methods. The division of regions and determination of delivery routes was based on districts and cities. The existing delivery method faced various challenges, including delivery delays and inefficient routes. This inefficiency results in potential financial losses for the company in terms of delivery costs. To assist the company in improving delivery efficiency, this research focuses on determining vehicle routes considering vehicle capacity (Capacity Vehicle Routing Problem). In solving and searching for solutions, the research uses Simulated-Annealing algorithm. The algorithm generated an initial solution randomly and improved the solution by changing the positions of consumers within a route and switching positions of consumers between routes to obtain the best solution. The computation time of the developed Simulated Annealing algorithm was quite efficient, taking only 2 seconds for 25 consumers. Based on the data from PT Tri Sapta Jaya, the best solution obtained was 615,319. This result was achieved using the Simulated Annealing algorithm with the parameters T0 = 100,000, Ta = 1, and α = 0.9.

Abstract

Teknologi memungkinkan akses informasi yang cepat dan efisien menjadi kunci penting dalam memenuhi kebutuhan informasi di era digital. Mesin pencari digital seperti Google, memainkan peran krusial dalam memberikan akses cepat dan akurat terhadap informasi yang diinginkan. Pengguna hanya perlu memasukkan kata kunci tertentu, dan dalam sekejap, berbagai sumber informasi relevan akan ditampilkan memberikan gambaran cepat tentang topik yang dicari tanpa harus membuka setiap laman. Mesin pencari menggunakan algoritma canggih untuk menilai relevansi dan kredibilitas laman web berdasarkan kata kunci yang dimasukkan oleh pengguna yang juga mempengaruhi posisi laman dalam hasil pencarian. Optimisasi kata kunci menjadi strategi penting bagi pemilik laman web untuk meningkatkan visibilitas mereka. Penelitian ini bertujuan untuk mengeksplorasi dampak kata kunci terhadap hasil pencarian di mesin pencari dari berbagai perspektif peneliti, dengan fokus pada bagaimana penggunaan kata kunci memengaruhi relevansi, akurasi, dan kepercayaan terhadap informasi yang diperoleh. Melalui tinjauan ini, diharapkan diperoleh pemahaman mengenai strategi optimasi kata kunci dan dampaknya dalam konteks pencarian informasi digital.

Abstract

Science education often faces challenges related to conceptual errors made by students, which can hinder their understanding of the material being taught. This study aims to identify and analyze common conceptual errors through the application of machine learning algorithms. The method employed in this research is a literature review approach, where various relevant studies are analyzed to understand the application of machine learning in the context of science education. The findings of the study indicate that several machine learning algorithms, such as large language models and interactive visualization techniques, can be utilized to detect misconceptions in students with higher accuracy and provide more personalized feedback. Although there are some challenges related to the accuracy and reliability of the systems used, the application of these techniques shows significant potential in enhancing the effectiveness of science education. Overall, the application of machine learning in science education can make a substantial contribution to helping teachers analyze and correct the conceptual errors made by students, ultimately improving the quality of the learning process. The implications of this research suggest the need for further development to create technology-based education systems that can better respond to students' learning needs.

Abstract

PT Nandya Karya Perkasa is a manufacturing company that produces motor vehicle spare parts. PT Nandya Karya Perkasa supplies its products to several automotive companies. The company faces issues with its inventory due to frequently fluctuating demand, often leading to order cancellations. Data from the past three months shows the company had to cancel approximately 19% of orders. This issue arises because of the limitations of the previously used application. Some crucial data, such as stock levels, which should support decision-making, is still missing, as the existing system only focuses on recording goods' inflows and outflows. This study aims to propose improvements to the use of the Inventory Management System application to facilitate the planning department in planning the production process, ensuring the availability of goods in the warehouse to meet all consumer demands. The method used to address this problem is a web-based application for monitoring goods, which can provide feedback for production planning improvements in case of demand changes. The system is developed using the Prototype method. A two-month trial has shown a reduction in order cancellations to 11%.

Abstract

Culture is an important part of English language teaching and learning. Students must be exposed to the culture related to the communication skills being taught. Textbook can be a medium for the teachers to present different kinds of culture along with the language content. Therefore, it is essential for an English textbook to properly include cultural contents. This study aims to investigate the target culture included in a junior high school English textbook used by many teachers in Indonesia. Qualitative descriptive design was employed in order to describe the target culture in the textbook without any manipulation to the data. Moran’s (2001) five dimensions of culture that include products, practices, perspectives, communities, and persons was used to analyze the data. The results found 61 items in the textbook that contained references to the target culture. The ways those target culture were presented were not vary. Almost all of those items were presented in words or passages.
