Abstract

Quality has become a research concern in the field of manufacturing or services. Currently, there are several tools available that can be used to improve service quality. Each tool has advantages and disadvantages, so integration between tools is needed to increase the effectiveness and efficiency of improvement efforts. Some tools that can be integrated to evaluate service quality comprehensively are SERVQUAL, KANO, and QFD. This scientific article provides experiential information on applying quality tool integration in the health sector. A hospital was selected as a case study for an example of the application of service quality improvement steps. The trial of SERVQUAL, KANO, and QFD integration in the case study showed that the integration of SERVQUAL and KANO selected 30% of critical service attributes that need improvement. Furthermore, QFD plays a role in executing the improvements effectively and efficiently.

Abstract

In this study, a marketing strategy for Xiaomi mobile phones in Indonesia was designed based on market share analysis using the Markov Chain method and SWOT analysis. The mobile phone market is very competitive, so to maintain and increase market share, it is necessary to understand the dynamics of consumer movement between brands. The Markov Chain method is used to model the possibility of customer movement from one brand to another based on historical market share data of several major brands, including Xiaomi, iPhone, Samsung, Oppo, Asus, and Vivo. After the Markov Chain, it is continued with SWOT Analysis and Marketing Strategy Design. Some strategies that Xiaomi can use include creating a user-friendly Xiaomi image, actively advertising and promoting both electronic and non-electronic media, using public figures as brand ambassadors, creating recycling movements, and creating a campaign. This strategy successfully increased consumers' probability of choosing Xiaomi as their main choice.

Abstract

Salah satu tujuan dari kegiatan Pengabdian kepada Masyarakat–Usaha Produk Unggulan Daerah (PM-UPUD) pendanaan 2025 ini adalah untuk menguatkan manajemen operasional produksi pada mitra Bina Logam, salah satu IKM produsen komponen logam di Jogorepuh, Pasrepan-Pasuruan. Hasil observasi menunjukkan bahwa proses produksi saat ini memiliki ketergantungan yang tinggi pada pemilik IKM dan seluruh instruksi produksi dilakukan secara lisan. Perencanaan kebutuhan dan target produksi dipikirkan secara manual hari demi hari untuk memenuhi permintaan pada tanggal tertentu. Situasi ini dapat menimbulkan risiko miskomunikasi, bottleneck, dan ketidakseimbangan beban kerja antar mesin. Perbaikan adaptif, efektif dan sederhana yang dilakukan pada aktivitas PM-UPUD pendanaan 2025 ini adalah merancang excel-based MRP yang mampu mengintegrasikan Master Production Schedule (MPS) dan perhitungan kebutuhan material secara otomatis hari demi hari hingga periode tertentu. Implementasi sistem ini membantu mitra dalam mengatur jadwal produksi, mengoptimalkan penggunaan mesin, dan meningkatkan transparansi komunikasi antar-pekerja. Model sistem ini dapat direplikasi pada IKM serupa untuk mendukung transformasi digital dan efisiensi proses produksi.

Abstract

The role of a production supervisor in manufacturing operations is a key factor in maintaining quality, stability, and the success of the production process. A production supervisor must maintain process effectiveness, output quality, and daily operational stability. Empirically, the scientific field that aligns with the scope of work of a production supervisor is Industrial Engineering. However, there is still a gap between the competencies of Industrial Engineering graduates and the qualifications required by companies for production supervisor positions. To fill this gap, this article aims to formulate qualification criteria for Industrial Engineering graduates interested in filling Production Supervisor positions in the manufacturing industry. The formulation of qualification criteria is based on job qualifications and requirements data from various types of manufacturers, collected through interviews with human resources department representatives and field observations. The research method used is a survey of experts experienced in the selection and development of human capital. Using the affinity diagram, the job qualifications and requirements are grouped into objective criteria, subjective criteria, and absolute requirements. Then, integrating the Pareto principle with the LINMAP method yields prominent qualification criteria. The results show that companies place the greatest emphasis on subjective qualifications, especially attitude (0,43) and software proficiency (0,43), followed by objective qualifications such as technical knowledge (0,36) and educational background (0,3).  These findings can be a basis for industry in the employee selection process and for universities in designing competency development programs and career preparation for Industrial Engineering students interested in careers as production supervisors.

Abstract

Complaints are a critical indicator that can reveal problems or failures in internal processes and require quick recovery. Therefore, complaint management must be well-designed. However, this will not be meaningful if failure, a cause of complaint, is not managed well. This article aims to establish a framework for failure management that can enhance the effectiveness of complaint management. Failure is a probability that can be prevented, anticipated, and managed. Failure management frameworks must be designed in accordance with global standards to achieve acceptance. In addition, the failure management framework must be flexible, robust, and comprehensive. Based on the definition of failure, ISO 31000:2018 provides a suitable basis for developing a failure management framework to enhance complaint management. Industry can utilize the findings to improve complaint management effectiveness by increasing stakeholder involvement in anticipating failures. This involves managing, assessing, preventing, handling, monitoring, reviewing, and recording failures to facilitate continuous improvement.
