Abstract

Penelitian ini menangani masalah tingginya tingkat penolakan (1,93%) dalam manufaktur komponen elektronik HE-EC2 di sebuah perusahaan semikonduktor, yang melebihi tingkat target 0,60%. Dengan menerapkan metode DMAIC (Define, Measure, Analyze, Improve, Control), penelitian ini secara sistematis mengidentifikasi, menganalisis, dan memperbaiki akar penyebab masalah penolakan. Analisis menunjukkan bahwa Gripper dalam proses Final Assy adalah penyumbang utama penolakan. Untuk mengatasi hal ini, parameter gripper, awalnya diatur pada 14 mm, dikurangi secara metodis menjadi 10 mm. Penyesuaian ini menghasilkan penurunan substansial dalam tingkat penolakan, dari 1,93% menjadi 0,57%. Analisis statistik menunjukkan bahwa tingkat cacat awal setara dengan DPMO (Defects Per Million Opportunities) sebesar 2751 dan nilai sigma sebesar 4,28. Setelah penyesuaian parameter, tingkat penolakan menurun menjadi DPMO sebesar 815, disertai peningkatan nilai sigma menjadi 4,65. Keberhasilan penerapan metode DMAIC, terutama dengan fokus pada parameter Gripper dalam proses Final Assy, menandakan peningkatan signifikan dalam kualitas produk. Penelitian ini menekankan efektivitas pendekatan sistematis dalam mengidentifikasi dan mengatasi faktor-faktor kunci yang memengaruhi penolakan, akhirnya mendekati tingkat penolakan yang ditargetkan sebesar 0,5%. Wawasan yang diperoleh dapat menjadi acuan berharga bagi perusahaan manufaktur yang bertujuan meningkatkan kualitas produk melalui optimasi proses yang tepat.

Abstract

Kontribusi pertumbuhan industri manufaktur tidak terlepas dari adanya peranan pekerja dalam pengelolaannya. Untuk mendapatkaan hasil ukuran kerja manusia yang terbaik, maka dibutuhkan pengukuran waktu kerja. PT. ABC belum mengetahui secara pasti berapa waktu standar dan tingkat produktivitas pada proses packing, sehingga perlu melakukan pengukuran waktu kerja. Metode studi waktu dan gerak telah digunakan untuk mengukur waktu kerja, yaitu menilai waktu standar dan produktivitas pekerja diberbagi sektor industri. Untuk menentukan waktu standar, diawali dengan menghitung waktu siklus dan waktu normal serta mempertimbangkan tingkat penyesuaian dan kelonggaran. Berdasarkan hasil pengolahan data dan pembahasan diperoleh bahwa waktu standar sebelum perbaikan sebesar 42,56 detik, sedangkan setelah perbaikan melalui koreksi gerak dan waktu, jumlah waktu standarnya menurun menjadi 40,79 detik. Untuk menghitung produktivitas pekerja berdasarkan hasil perbandingan jumlah output produk yang dihasilkan dengan jumlah pekerja. Hasil perhitungan produktivitas pekerja pada proses packing setelah koreksi perbaikan sebesar 96,59%, hal ini menunjukkan bahwa produktivitas pekerja dapat dikategorikan baik dan terjadi peningkatan produktivitas pekerja sebesar 3,5%.

Abstract

In the era of Industry 4.0, digital transformation integrates advanced technologies such as the Internet of Things (IoT), artificial intelligence, and data-driven manufacturing, driving advancements in science and technology. Within this framework, this study focuses on the design and fabrication of a cantilever-type 3D printer aimed at producing a prototype capable of efficient and functional 3D object printing. Additive Manufacturing (AM) technology, particularly Fused Deposition Modeling (FDM), enables the conversion of digital designs into physical products through the layer-by-layer deposition of material. The 3D printer is designed using the VDI 2221 methodology, which encompasses four key phases: task clarification, conceptual design, embodiment design, and detailed design. A key consideration during the design process is the use of filaments derived from plastic bottle waste to mitigate environmental impact. The results identify the Cartesian model variant (Variant 1) as the optimal solution, selected based on functional performance, cost efficiency, and ease of assembly. This machine achieves nozzle temperatures up to 270°C and bed temperatures up to 80°C, with a total production cost of Rp 3,657,000.00. These findings demonstrate the potential of 3D printing technology to advance plastic waste recycling and promote the development of more sustainable 3D printing solutions.

Abstract

Blue Ocean Leadership (BOL) is a strategic leadership approach that focuses on creating new market space, redefining the boundaries of competition, and optimizing resources to achieve sustainable competitive advantage. Although it has been widely applied in the business sector, empirical studies on BOL in the context of higher education, especially in Indonesian Private Universities (PTS), are still limited. This research aims to explore the implementation of BOL in XYZ University Batam, a large private university that is facing intense competitive pressures and demands for organizational transformation. Using a qualitative case study approach, the research relies on in-depth interviews with university leaders, lecturers, and education staff, as well as a review of the institution's strategic documents. The findings show that the implementation of BOL contributes to driving organizational innovation, improving the efficiency of internal processes, and generating a distinctive value proposition that differentiates the university from its competitors. However, there are a number of challenges in implementation, including organizational cultural resistance, limited resource capacity, and low technical understanding of the operational principles of BOL. This research makes a theoretical contribution to the strengthening of strategic leadership studies in the higher education sector and provides practical recommendations for PTS in adopting more responsive, adaptive and innovative leadership strategies to strengthen the institution's competitive position amid increasingly complex global dynamics.

Abstract

This study aims to understand the role of organizational culture in improving employee performance at Sekolah Tinggi Ilmu Ekonomi Bentara Persada (STIE BP) Batam. A qualitative approach was employed, using triangulation techniques to validate data through interviews and direct observations. The findings reveal that the organizational culture established at STIE BP characterized by values such as honesty, responsibility, care, fairness, and consistency has been internalized by employees and serves as a guiding principle in carrying out their duties and responsibilities. This culture is reflected in routine activities such as staff recollections, the use of symbols and uniforms, as well as the implementation of the institution’s motto and vision-mission. In addition, the quality assurance system and the application of Key Performance Indicators (KPIs) contribute to increased productivity and work motivation. The findings also indicate that organizational culture fosters a sense of belonging, enhances self-confidence, and strengthens employee engagement with the institution. Thus, a strong organizational culture not only functions as a tool for social control but also serves as a key driver of employee performance.
