Abstract

The demand for canting stamps continues to increase along with the development of batik. This need cannot be met by canting cap producers because their productivity is low as a result of the process of making canting caps still being manual. This research developed a canting cap using the conductive material Acrylonitrile Butadiene Styrene (ABS)–electroformed by copper (CABS-EBC). The research procedure consists of 1) design and 3D-printing procedure and 2) electroforming and assembling procedure. Design and 3D-printing procedures consist of preparation steps, designing, slicing process, and printing process. Electroforming procedure consists of preparation, pre-treatment, electroforming. Then proceed with the assembly steps. The process is depicted through diagrams, pictures/photos and explained step by step. From the experimental results it can be concluded that canting caps can be made using conductive ABS and copper electroforming materials

Abstract

Operating room scheduling is a complex problem due to the limited availability of surgeons, nurses, and operating rooms, as well as the variability in surgery durations. Inaccurate predictions or scheduling may cause conflicts such as overlapping surgeon schedules, violations of contamination level restrictions, and unavailability of nurses or rooms, ultimately reducing the quality of hospital services. This study integrates multiprocedure surgery duration prediction using machine learning with scheduling optimization based on genetic algorithms. The prediction model considers the American Society of Anesthesiologists (ASA) physical status classification, patient profiles, and sets of surgical procedures variables. Scheduling optimization employs a lexicographic approach with three main objectives: minimizing patient waiting time, nurse overtime, and operating room idle time, while ensuring surgeon presence during critical phases and nurse availability according to shifts. The results show that the Catboost algorithm achieves the best prediction performance. Incorporating the ASA variable reduces prediction errors by 33.880 minutes in MAE and 55.575 minutes in RMSE compared to model without the ASA feature. The optimization model successfully eliminates all scheduling conflicts, ensuring full compliance with medical procedure constraints. Recovery bed utilization remains efficient, with a maximum of five units used, representing less than 50% of the total capacity.

Abstract

Research on new product development (NPD) has led to tools, methods, models, and frameworks that enable researchers to develop better products. However, a comprehensive review of the methods, models and frameworks related to NPD is lacking. This literature study aims to identify research trends, methods, and frameworks used in NPD between 2010 and 2019. A systematic literature review is conducted by developing a structured research protocol. An analysis of 50 selected papers shows that research on NPD can be categorized into 15 conceptual papers, six review papers, 28 case studies, and one survey paper. This paper provides an overview of each tool and presents future research opportunities. This paper concludes that future research can be directed toward combining several methods to design products that satisfy consumer desires with shorter design times, aspects of NPD collaboration, and aspects of changing consumer preferences.

Abstract

Nglanggeran Village, located in Gunungkidul Regency, Yogyakarta, has substantial potential for the development of the local cocoa industry. Cocoa production in this village is integrated and managed by Griya Cokelat Nglanggeran, a community-based enterprise that focuses on processing cocoa beans into various derivative products. Despite its strong potential, the production process still faces several inefficiencies, particularly in the cocoa powder manufacturing stage. These inefficiencies hinder productivity and reduce overall process effectiveness. To address these challenges, this study applies the Lean Manufacturing approach, which emphasizes waste reduction and value enhancement throughout the production chain. Specifically, the research utilizes Value Stream Mapping (VSM) and Process Activity Mapping (PAM) to systematically visualize the production flow, identify non-value-added (NVA) activities, and analyze existing sources of waste. In addition, Fishbone Diagram, Failure Mode and Effect Analysis combined with Simple Additive Weighting (FMEA-SAW), and Fault Tree Analysis (FTA) are employed to trace the root causes of inefficiencies and propose prioritized improvement strategies based on risk levels. The findings indicate that, of the entire set of observed production activities, 196 were classified as waste, while only 24 contributed direct value. Among the seven types of waste, motion and transportation were identified as the most dominant, leading to the need for improvements in workspace layout and material handling management. After implementing corrective measures derived from the analytical results, the total duration of NVA activities decreased significantly from 3,059,830 seconds to 261,301 seconds, representing a 76.98% improvement in process efficiency relative to the total production time. These findings demonstrate that the application of Lean Manufacturing tools can significantly optimize cocoa powder production at Griya Cokelat Nglanggeran, while also providing a feasible model for other small-scale agro-industry enterprises seeking sustainable operational efficiency.

Abstract

Used cooking oil can be utilized as an alternative raw material for making batik wax. Recycling batik wax involves using recycled materials such as used wax, used cooking oil, and other substances like paraffin, microwax, colophonium resin, and damar resin. The recycling of used wax and the utilization of used cooking oil are crucial for the batik industry as they reduce production costs and environmental pollution. A combination of Taguchi and Grey Relational Analysis (GRA) method is employed to obtain optimal values for the response characteristics of line width continuity and permeability of wax. Recycled and new wax is applied to mori fabric and compared based on batik quality criteria. The research results indicate that the optimal composition for recycled wax consists of 510 grams of used wax (41.5%), 36 grams of used cooking oil (2.9%), 102 grams of paraffin (9.8%), 84 grams of microwax (6.8%), 300 grams of colophonium resin (24.4%), and 180 grams of damar resin (14.6%). According to batik experts' assessments, the quality of recycled batik wax is equivalent to that of new batik wax. Recycled batik wax has the melting point of 67.9 °C, the viscosity value of 90.15 cP, and the production cost of Rp 30.909,00.
