Abstract

In the field of sports, the use of information technology is used to support performance in a sport. Data visualization is the answer to simplifying complex data into a graphical format so that it's easier to understand the data. Data management for one sport is an important process that must be carried out by sports. With good data management, the company gets more value. This added value is like decision support information, in order to be able to increase operational efficiency and effectiveness. This research uses data from one of the sports branches, Bass ball, items obtained from the internet, namely 2426 data. The research was conducted with the help of Google Data Studio tools for making dashboards. The results obtained are that there are several elements that help in making it easier to read information, namely scorecard elements, Pie Chart elements, bar chart elements, geographic chart elements, and table elements. The Record count element displays the total number of records, the average number of players, On the Pie Chart displays product insights in percent, the average attendance is obtained. The bar chart element displays the total player attendance each month, the player with the highest attendance being in May

Abstract

This training is to give the method how to master to speak the English for the students of LKP Royal Skill Training Center. They do not have basic skill of speaking the English. The speakers tell about the technique to study speak English step by step. The methods are used in the descriptions in the field or the location. The students are studying to focus on the computer at the LKP Royal Skill Training Center, they are 18 (eighteen) students or the participants. They are 3 (three) methods to master the speaking English, namely: speak to themselves, to watch the western movie and listen to the English music or songs, the last is to give the respon from the speakers who talk about the materials in English so the listeners or the students have to respon in English so that they will have good habits in English by speaking in English. A few students give the respon by asking the questions and the speakers. The participants are so happy in the training because they have had tricks to master speaking English step by step by doing themselves.

Abstract

Abstract: The inability to accurately monitor the lifespan of motorcycle batteries can lead to sudden failures, disrupt user activities, and increase maintenance costs. This issue is exacerbated by the absence of a predictive system that can assist users and workshops in planning maintenance and managing battery inventory effectively. This study aims to develop a battery lifespan prediction model for motorcycles using the Double Moving Average (DMA) method. The model is built based on historical data from 12 motorcycle units, including usage frequency, duration, terrain conditions, and maintenance habits. Forecasting is conducted through two stages of moving averages followed by trend parameter calculations. Evaluation results show that the model has a high level of accuracy, with MAPE = 0.10, MAD = 1.68, and RMSE = 2.14, indicating very low prediction errors. In addition, DMA is also used to forecast product demand at PT Anugerah Karya Abiwara Kisaran to prevent stock shortages. The system is developed using Visual Studio 2010 and Microsoft Access and has proven effective in supporting maintenance planning and inventory control. With its high accuracy and efficiency, the results of this study provide tangible contributions to decision-making in battery maintenance and inventory management. Keywords: battery; DMA; motorcycle; prediction. Abstrak: Ketidakmampuan dalam memantau usia pakai aki sepeda motor secara akurat dapat menyebabkan kerusakan mendadak, mengganggu aktivitas pengguna, serta meningkatkan biaya perawatan. Permasalahan ini diperburuk oleh tidak tersedianya sistem prediktif yang membantu pengguna dan bengkel dalam merencanakan perawatan serta mengelola persediaan aki secara efisien. Penelitian ini bertujuan untuk mengembangkan model prediksi usia pemakaian aki sepeda motor dengan menggunakan metode Double Moving Average (DMA). Model dibangun berdasarkan data historis dari 12 unit sepeda motor yang mencakup frekuensi penggunaan, durasi, kondisi medan dan kebiasaan perawatan. Proses peramalan dilakukan melalui dua tahap perataan bergerak, yang kemudian diikuti dengan perhitungan parameter tren. Hasil evaluasi menunjukkan bahwa model ini memiliki tingkat akurasi yang tinggi, dengan nilai MAPE sebesar 0,10, MAD sebesar 1,68, dan RMSE sebesar 2,14, yang mengindikasikan tingkat kesalahan prediksi yang sangat rendah. Selain itu, metode DMA juga diterapkan untuk meramalkan permintaan produk pada PT Anugerah Karya Abiwara Kisaran guna mencegah terjadinya kekurangan stok. Sistem dikembangkan menggunakan Visual Studio 2010 dan Microsoft Access, serta terbukti efektif dalam mendukung perencanaan perawatan dan pengendalian persediaan. Dengan akurasi dan efisiensi yang tinggi, hasil penelitian ini memberikan kontribusi nyata dalam pengambilan keputusan terkait pemeliharaan aki dan manajemen inventori. Kata kunci: baterai; DMA; prediksi; sepeda motor.

Abstract

Utama Aluminium is a business engaged in the sale of glass cabinets. The problem faced in the operational activities of this business is irregularity in the management of raw material supplies. This condition is caused by inconsistency in supply from suppliers, which results in stock shortages and delays in orders, and on the other hand, there have also been instances of excess raw materials. The purpose of this study is to design a raw material inventory management application system for the glass cabinet production process, in order to optimize the management of raw material inventory, which has been a challenge in production activities at Utama Aluminium. The method used in this study is a descriptive qualitative method, with a case study approach at the company concerned. The results of implementing a web-based supply chain management (SCM) system showed a significant increase in efficiency: process time decreased by up to 40% through system automation and integration, operational costs were reduced by up to 25% due to labor efficiency and a decrease in error rates, stock accuracy increased to 95% with supplies matching demand, lead time was reduced by an average of 2 days, and the number of product returns decreased by up to 30% thanks to more accurate data information. This research can help the MSME sector improve distribution efficiency and inventory accuracy.
