Abstract

Intisari—Dengan Persaingan yang cukup ketat dalam dunia industri beton pracetak saat ini tentunya membuat PT.ABC sebagai manufaktur beton pracetak dituntut untuk dapat menghasilkan produk yang memenuhi ekspetasi pelanggan baik dari segi waktu dan kualitas. Untuk mencapai hal tersebut perlu dilakukan analisis pemborosan dengan menggunakan pendekatan Lean supply chain sehingga akan meningkatkan efisiensi sistem manufaktur. Pendekatan ini dilakukan dengan menggambarkan aliran informasi perusahaan melalui tools Value Stream Mapping (VSM). Aktivitas Perusahaan akan di kelompokkan dalam value added, non value added, dan necessary non value added. Dari pemetaan VSM terlihat pemborosan banyak terjadi di aliran rantai pasok. Hal ini terlihat dari Terjadinya keterlambatan kedatangan material utama dari supplier mengakibatkan proses terhenti, Perubahan rencana produksi yang mendadak, Terganggunya penjadwalan produksi yang disebabkan oleh lead time yang panjang. Oleh karena itu, perlu dilakukan upaya yang efektif dan efisien untuk meminimasi pemborosan di aliran rantai pasok agar dapat memenuhi ekspetasi pelanggan. Penelitian ini berhasil merinci besar value added time adalah 2.025 menit, total necessary but non value added time adalah 335 menit sehingga total supply chain lead time adalah 2.360 menit.Abstract— With the strict competition in the precast concrete industry at this time, causing PT.ABC as a precast concrete manufacturing is required to be able to produce products that meet customer expectations both of time and quality. To achieve this, a waste analysis needs to be done using the Lean supply chain approach so that it will improve the efficiency of the manufacturing system. This approach is carried out by describing the flow of company information through Value Stream Mapping (VSM) tools. Company activities will be classification in value added, non value added, and necessary non value added. From the VSM mapping it is seen that a lot of waste occurs in the supply chain flow. This can be seen from the delay in the arrival of main material from the supplier resulting in the process stalled, a sudden change in production plans, disruption of production scheduling caused by a long lead time. Therefore, effective and efficient efforts are needed to minimize waste in the supply chain flow in order to meet customer expectations. This research succeeded in detailing the value added time is 2,025 minutes, the total necessary but non value added time is 335 minutes so that the total supply chain lead time is 2,360 minutes.

Abstract

This study aims to determine the influence of learning models and practicum activities on students' conceptual understanding, as well as to examine the interaction between learning models and practicum activities on students' conceptual understanding. The research was conducted using a quantitative descriptive method with a 3x2 factorial experimental design, and the data were analyzed using two-way ANOVA to identify differences in variance between two treatment groups. Based on the analysis results, it can be concluded that there is an effect of learning models on students' conceptual understanding. However, there is no effect of conducting practicum activities either at the beginning or at the end of the learning process on students' conceptual understanding. Additionally, there is no interaction between learning models and practicum activities, as practicum activities are considered part of the learning model. The discrepancy between the results and theoretical expectations is influenced by several factors, including students' initial understanding and skills in conducting practicum activities. Furthermore, inaccurate time estimation in executing each step of the learning syntax also contributed to these findings.
