Perbaikan Kinerja Defect free supply chain Dengan Pendekatan Simulasi Model System Dynamics (Studi Kasus: PT. NPC)
Full text linkThe garment industry plays an important role in supporting the Indonesian economy with a significant growth of 15.08% in 2019. This study aims to reduce the defect rate at Line 9 Factory C, PT. NPC to strengthen supply chain performance, especially performance related to the defect free supply chain. This study will explore in detail the production defect rate using the Seven Tools approach and design a defect reduction strategy with a Dynamic System Simulation approach. The Seven Tools method helps identify dominant defects such as Poor Shape, Open Seam, and Broken Stitch through Check Sheet, Pareto, and Fishbone Diagram analysis. The simulation results show that the Company's existing condition has an average defect rate of 12.15%, exceeding the company's target of less than 10%. The proposed strategic steps are to conduct interventions in the form of intensive training for operators and the addition of Inline QC officers. The simulation results show that training reduces the defect rate by 0.70%, while the addition of Inline QC officers reduces the defect rate by 1.16%. The combination of both strategies resulted in the largest reduction in defect rates of up to 1.34%, indicating a positive direction of improvement towards the company's target. The implementation of quality control strategies not only increased operational efficiency, but also increased the company's supply chain performance.

Analisis Terstruktur Faktor Risiko Operasional Industri Manufaktur Kertas Menggunakan Pendekatan ISM-MICMAC
Full text linkPenelitian ini menganalisis faktor risiko yang memengaruhi kinerja operasional manufaktur kertas dengan pendekatan ISM (Interpretive Structural Modeling) dan MICMAC. Sepuluh faktor utama teridentifikasi melalui wawancara dan observasi, termasuk produk gagal, produk ditolak bagian quality control (QC), produk dikembalikan konsumen, masalah mesin, serta keterampilan pekerja. Hasil penilaian menunjukkan produk dikembalikan konsumen dan keluhan pelanggan memiliki skor tertinggi (mean 4,0), diikuti kesalahan manusia (mean 3,7) dan produk ditolak QC (mean 3,3). Analisis ISM menempatkan faktor produk gagal (RF1), produk ditolak QC (RF2), dan produk dikembalikan (RF3) pada level tertinggi dengan driving power = 10, sehingga menjadi prioritas strategis. MICMAC mengklasifikasikan seluruh faktor dalam cluster linkage, menandakan tingkat keterkaitan yang tinggi antar risiko. Hasil ini mengimplikasikan bahwa optimasi pengendalian kualitas harus difokuskan pada reduksi defect produk, penguatan inspeksi QC, serta peningkatan kecepatan respon terhadap keluhan konsumen. Selain itu, departemen QC perlu menetapkan standar evaluasi berbasis data numerik untuk menurunkan tingkat produk cacat, sementara departemen produksi harus memperketat jadwal perawatan mesin guna mencegah downtime. Dengan demikian, perusahaan dapat merancang strategi mitigasi risiko yang lebih efektif, menekan biaya akibat retur konsumen, serta meningkatkan daya saing di industri manufaktur kertas
A bibliometric analysis of leadership management
Full text linkBeing a leader means having to use the resources that are available to you, whether they be material or human, in order to achieve goals and maintain organizational unity. Analysts define leadership as the process by which one individual inspires a group of people to work together toward a single objective. The main objective of this study was to quantify and identify the current state of leadership management through bibliometric analysis, to identify emerging issues, and to lay the foundation for subsequent research in the area. We use bibliometric analysis with VOS Viewer and have outlined the research literature from 2013 to 2023 to demonstrate the outlook for leadership management. This paper resulting in a refined dataset of 3691 articles. This study provides an in-depth bibliometric analysis of leadership management, revealing the global research landscape, international collaboration, publication trends, research hotspots, and emerging frontiers. The global output of publications maintains a balanced growth, highlighting the active engagement in this field.

Kepuasan konsumen sebagai moderasi kenaikan PPN dan celebrity endorser terhadap minat beli
Full text linkTechnological advances and changes in tax regulations, competition in the business sector present various possibilities and difficulties for business people who want to increase consumer interest in their products. With consumer satisfaction as a moderator variable, the purpose of this study is to determine whether celebrity endorsers and VAT increases affect purchase intention. This study collected data using purposive techniques and a quantitative approach using a questionnaire involving 100 respondents who are users of skin care products and have seen promotional advertisements for skin care products on social media in the Special Region of Yogyakarta. Data were analyzed using Structural Equation Modeling (SEM) techniques with AMOS software. The results showed that celebrity endorsers and VAT increases have a positive effect on consumer interest, which shows that these two strategies can increase consumer interest in making purchases. The results also reveal that the moderating variable of customer satisfaction can moderate the relationship between the increase in VAT and celebrity endorsers on purchase intention. This shows that an increase in VAT and celebrity endorsers can increase consumer buying interest, so both can be used as effective marketing strategies. In addition, customer satisfaction plays an important role as a moderator that strengthens the influence of these two factors on purchase intention
Techno-economic analysis of the transition from off-Grid to on-grid electricity in the mining industry
Full text linkThe mining sector's reliance on off-grid diesel generators imposes significant economic and environmental costs, including high energy expenditures and substantial greenhouse gas emissions. While existing techno-economic studies have explored renewable hybrids for off-grid mining operations, there remains a critical gap in evaluating grid-connected transitions—especially in emerging economies with coal-dependent grids like Indonesia. This study aims to find out how can transitioning from diesel to grid electricity in Indonesia’s mining sector achieve cost savings and emission reduction. Through integrated Levelized Cost of Electricity (LCOE), Net Present Value (NPV), and CO₂ emission analysis of a mining company as a case study, we demonstrate two key novel contributions: (1) a framework for quantifying trade-offs between cost savings and emission reductions in coal-reliant grids, and (2) empirical evidence that grid adoption reduces energy costs by 66% (from 0.17/kWh) while delivering a projected NPV of $14.46 million (IRR: 32.34%). Moreover, switching to on-grid PLN shows a potential emission reduction of 2,054 tons/year (15% decrease). These findings highlight the dual imperative of grid electrification and renewable integration for sustainable mining, offering policymakers and industry stakeholders a replicable model to balance economic and environmental goals in resource-intensive sectors
The Role of Interpersonal Communication in The Family: (Literature Review to Minimize Divorce Cases)
Full text linkOne of the strong bonds resulting from a sustainable relationship between individuals is marriage. However, along the way, commitment in marriage is often accompanied by challenges and problems that often occur. Even if this situation cannot be adequately resolved, it has the potential for a divorce rate that continues to increase. Referring to data from the Central Statistics Agency (BPS) of Indonesia in 2024 explains that 408,347 cases continued to emerge and were spread across several major cities, such as West Java, East Java, Central Java, North Sumatra, and DKI Jakarta. So, it can seriously impact other family members, from children to closest relatives. Ironically, some of the adverse effects that arise can be in the form of trauma, inhibited emotional development and drastic changes in a person's mood. This study aims to analyze the role of interpersonal communication in the family in more depth. Using a descriptive qualitative method, the study results show that a concrete strategy is needed to optimise family life, one of which is the openness of communication. That way, divorce cases can be minimized to create a comfortable environment and form a positive mindset for children.

Challenges Implementation of The Permendikbudristek PPKS In 6 Universities In Yogyakarta Province
Full text linkPermendikbudristek Number 30 of 2021 concerning Prevention and Handling of Sexual Violence in Higher Education Environments (Permendikbudristek PPKS) is over 3 years old. All universities, both public and private, are required to comply with these regulations.This step was taken by the Ministry of Education and Culture as an effort to encourage a world of education free from sexual violence. Implementing the PPKS Ministerial Education and Culture Regulation is not easy, especially in the process of preventing and handling sexual violence. This article discusses 3 main things, firstly regarding the understanding of higher education academics in Yogyakarta regarding these regulations, secondly the implementation of the PPKS Permendikbudristek and thirdly the challenges faced by the PPKS Task Force. This research uses empirical juridical methods. The PPKS Task Force studied has also carried out efforts to prevent and handle sexual violence, but the priority in implementing these two things depends on the resources the university has. The challenges faced by the PPKS Task Force in prevention efforts include human resources, learning from the Ministry of Education and Culture's PPKS modules, resistance from higher education leaders in forming the PPKS task force, and the lack of clarity regarding the PPKS task force in the university's organizational structure. The challenges in handling sexual violence faced by the PPKS Task Force are that cases stop because the reporter disappears, there is a lack of human resources, a lack of understanding and empathy for the PPKS Task Force, there is a lack of mentoring facilities at universities, lack of centralized handling of sexual violence in the PPKS Task Force, and finally, the system is not yet clear.
