Abstract

The utilization of technology across various sectors has proven effective in addressing numerous related challenges, including in the field of animal husbandry. One recurring issue in the duck farming business owned by Mrs. Juntak is the determination of duck productivity. Making decisions on whether a duck is categorized as productive or not is a critical process that directly impacts the profit gained from the sale of its eggs. On the other hand, high market demand compels farmers like Mrs. Juntak to consistently provide products in sufficient quantity and with high quality. Therefore, identifying ducks with high productivity is essential to support both market demand and sales performance. This study applies data classification using the C4.5 algorithm, a well-established method for constructing decision tree models. The C4.5 algorithm is an extension of the earlier ID3 method, offering greater sensitivity in determining decisions based on the features used. The aim of this research is to identify the most influential determining factors and their derivatives that affect the productivity of laying ducks. The final output of the study is a branched decision tree that contains valuable insights into the key factors influencing duck productivity. The results indicate that feed is the most significant factor affecting the productivity of laying ducks, compared to other variables considered in the study.

Abstract

The company faces a recurring issue related to product defects, which affect both production efficiency and customer satisfaction. To address this problem, this study applies a causal and experimental research approach using the Taguchi Method as a systematic tool for process optimization and quality improvement. The Taguchi Method is employed to identify the optimal combination of process parameters that significantly influence the quality of cardboard boxes while minimizing defects and production variability. Based on the results of data processing and analysis, it can be concluded that the optimal combination of factor levels that significantly influence the improvement of carton box product quality, as determined through the Taguchi experimental design, is Speed at level 2 (280 mpm), Air Supply at level 2 (0.88 MPa), and Steam Supply at level 2 (5 MPa). These optimal conditions demonstrate the most effective balance between production efficiency and product consistency, and must be properly maintained to ensure stable and high-quality output. Furthermore, improvement efforts based on the Taguchi method emphasize the importance of the human factor or operator in sustaining these optimal settings. Operators must be trained to respond appropriately to changes in process parameters and to maintain consistent conditions during production. The results of this research confirm that the Taguchi Method provides a robust, data-driven framework for continuous improvement, helping  reduce defects, optimize process performance, and achieve sustainable quality enhancement in its cardboard manufacturing operations

Abstract

Strategic supplier selection plays a pivotal role in maintaining the operational stability and competitiveness of & Petcare. Currently, the primary challenge lies in the reliance on a manual, intuition based selection process, which is prone to subjectivity and inefficiency in decision making. This study aims to design and build a web based Decision Support System (DSS) by implementing the Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) to generate objective supplier recommendations. The system development methodology adopts the Waterfall model, encompassing analysis, design, implementation, and testing phases. In this case study, the system evaluates ten supplier alternatives based on five fundamental criteria: product quality, service, distance, price, and delivery time. The computational results demonstrate that the PROMETHEE method effectively provides accurate rankings, with Supplier 5 achieving the top position with the highest Net Flow value of 0.6222. Validation through Black Box and White Box testing confirms that all system functionalities and logic structures operate correctly and efficiently. The implementation of this system proves effective in enhancing accuracy, objectivity, and time efficiency in the supplier selection process.

Abstract

Kuat tekan dinding pasangan bata merupakan parameter penting dalam perencanaan struktur bangunan dan dipengaruhi oleh kuat tekan bata satuan serta interaksi antara bata dan spesi. Namun, hubungan antara kuat tekan bata satuan dan kuat tekan dinding pasangan bata masih sangat bergantung pada karakteristik material dan metode konstruksi yang digunakan. Penelitian ini bertujuan untuk mengkaji hubungan kuat tekan bata satuan dan kuat tekan dinding pasangan bata melalui studi eksperimental menggunakan material lokal. Pengujian tekan dilakukan terhadap beberapa sampel bata satuan untuk memperoleh nilai kuat tekan rata-rata, sedangkan satu spesimen dinding pasangan bata skala penuh diuji di bawah beban aksial hingga mengalami keretakan dan keruntuhan. Hasil penelitian menunjukkan bahwa bata satuan memiliki variasi kualitas yang cukup signifikan, dengan nilai kuat tekan rata-rata sebesar 134,70 kg/cm², yang mencerminkan ketidakseragaman kualitas bata merah lokal akibat proses produksi tradisional. Pengujian dinding pasangan bata menunjukkan bahwa retak mulai terjadi pada kuat tekan sebesar 182,78 kg/cm² dengan deformasi rata-rata dinding sebesar 1,57 cm. Pola keruntuhan didominasi oleh retak vertikal dan retak sepanjang sambungan spesi, yang mengindikasikan bahwa mekanisme keruntuhan dinding sangat dipengaruhi oleh interaksi antara bata dan spesi. Hasil penelitian ini menegaskan bahwa kinerja tekan pasangan bata tidak dapat dinilai hanya berdasarkan kuat tekan bata satuan, serta memberikan pemahaman awal yang dapat digunakan sebagai referensi untuk perencanaan dan penelitian lanjutan

Abstract

Industrial organizations are currently operating in increasingly complex environments characterized by high levels of uncertainty, rapid technological advancement, and growing sustainability pressures. Under these conditions, improvements in industrial performance can no longer be effectively achieved through isolated technical or managerial approaches. This study aims to develop a systems-based framework that integrates operations engineering, management systems, and human resource management (HRM) to support sustainable industrial performance using a System Dynamics approach. The research methodology is systematically structured, encompassing problem formulation, system boundary definition, causal loop diagram development, stock-flow modeling, model validation, and policy scenario simulation. Simulation results indicate that fragmented strategies generate only limited short-term performance improvements. In the baseline scenario, the Sustainable Industrial Performance Index increases from 70.0 to 70.9 within a two-month period. An HRM-focused strategy raises the index to 71.9, while an operations-oriented strategy achieves a higher improvement, reaching 72.8. The most substantial improvement is observed under an integrated policy scenario that combines HRM investment, enhanced operational reliability, and managerial alignment, resulting in an index increase to 73.8 over the same period. These findings confirm that integrated policies create synergistic effects and highlight the critical role of feedback mechanisms and time delays in shaping industrial performance dynamics. This study concludes that sustainable industrial performance emerges from the dynamic interaction among technical, managerial, and human subsystems and provides both theoretical contributions to industrial systems modeling and practical value as a decision-support foundation for strategic policymaking.
