Forecasting Shoe Sales Volume with Exponential Smoothing Method at PT Kujang Utama Antasena - Bogor

PT Kujang Utama Antasena is a shoe industry company specifically for security. The purpose of this study is to forecast or predict sales. This study uses a quantitative method with exponential smoothing, smoothing factor/constant (?) of 0.2. In production activities, forecasting is carried out to determine the amount of demand for a product and is the first step of the production planning and control process to reduce uncertainty so that an estimate that is close to the actual situation is obtained. The exponential smoothing method is a moving average forecasting method that gives exponential or graded weights to the latest data so that the latest data will get a greater weight. In other words, the newer or more current the data, the greater the weight.

IMPLEMENTASI METODE DMAIC (DEFINE, MEASURE,ANALYZE, IMPROVE, CONTROL) UNTUK MENURUNKAN CACAT BONDING SEPATU DI GEDUNG 2 (DUA) PADA PT. PARKLAND WORLD INDONESIA

This study focuses on how to control defective products at PT. Parkland World Indonesia, a company engaged in the Adidas brand shoe industry for the period April 2020 to March 2021, the average product achievement reaches 8.37%, while the company wants Zero Defect. The purpose of this study is to reduce bond defects through an approximation approach, where we observe and conduct tests in order to improve performance and reduce. The method to guarantee the quality of the product produced is DMAIC (Define, Measure, Analyze, Improve, Control) which is a data-based problem solving approach that helps to optimally correct defects caused by the production process can decrease. The results of the analyzed data showed 5 CTQ (Critical to Quality) bonds with the highest percentage of bonding stabilizer at 43.70%. The conclusions and recommendations that can be drawn from this study are the causes of shoe ties that can be prevented by implementing several proposed improvements, by providing the latest SOPs, maximum WIP visual standards, brush change visual systems, and providing RCA (root cause analysis) board meetings

Application of Bacterial Cellulose in the Textile and Shoe Industry: Development of Biocomposites

Several studies report the potential of bacterial cellulose (BC) in the fashion and leather industries. This work aimed at the development of BC-based composites containing emulsified acrylated epoxidized soybean oil (AESO) that are polymerized with the redox initiator system hydrogen peroxide (H2O2) and L-ascorbic acid and ferrous sulfate as a catalyst. BC was fermented under static culture. The polymerization of the emulsified organic droplets was tested before and after their incorporation into BC by exhaustion. The composites were then finished with an antimicrobial agent (benzalkonium chloride) and dyed. The obtained composites were characterized in terms of wettability, water vapor permeability (WVP), mechanical, thermal and antimicrobial properties. When AESO emulsion was polymerized prior to the exhaustion process, the obtained composites showed higher WVP, tensile strength and thermal stability. Meanwhile, post-exhaustion polymerized AESO conferred the composite higher hydrophobicity and elongation. The composites finished with the antimicrobial agent showed activity against S. aureus. Finally, intense colors were obtained more uniformly when they were incorporated simultaneously with the emulsified AESO with all the dyes tested.

PERLINDUNGAN HUKUM BAGI PEMEGANG HAK DESAIN INDUSTRI SEPATU TERHADAP IMITASI (Studi Perbandingan dengan Amerika Serikat)

The development of the shoe industry in Indonesia today raises new problems where the similarity of shoe designs between several brands is a new problem that arises. The shoe industry design rights holders which should be highly protected have not fully received strong legal protection and there are no regulations that discuss in detail about design imitation. This writing uses a comparative method, namely the author compares with the United States that has protected industrial design rights holders since 1989 and has proven successful in protecting industrial design rights holders, therefore this comparison is important so that regulations on industrial design rights in Indonesia can benefit rights holders.

Towards footwear manufacturing 4.0: shoe sole robotic grasping in assembling operations

In this paper, we present a robotic workcell for task automation in footwear manufacturing such as sole digitization, glue dispensing, and sole manipulation from different places within the factory plant. We aim to make progress towards shoe industry 4.0. To achieve it, we have implemented a novel sole grasping method, compatible with soles of different shapes, sizes, and materials, by exploiting the particular characteristics of these objects. Our proposal is able to work well with low density point clouds from a single RGBD camera and also with dense point clouds obtained from a laser scanner digitizer. The method computes antipodal grasping points from visual data in both cases and it does not require a previous recognition of sole. It relies on sole contour extraction using concave hulls and measuring the curvature on contour areas. Our method was tested both in a simulated environment and in real conditions of manufacturing at INESCOP facilities, processing 20 soles with different sizes and characteristics. Grasps were performed in two different configurations, obtaining an average score of 97.5% of successful real grasps for soles without heel made with materials of low or medium flexibility. In both cases, the grasping method was tested without carrying out tactile control throughout the task.

Analysis of the quality of modern polymer materials of sole

Modern polymer sole materials used in the molding of the sole in the production of shoes are considered. A qualitative analysis of the composition of the compositions used was carried out. The positive and negative characteristics of the resulting products are revealed. In the course of the analysis, a table was created comparing the characteristics of the materials considered for the optimal and effective choice of production material in the shoe industry.
