Abstract

In response to increasing competition in the manufacturing sector, PT X—a copper busbar manufacturing company—implemented Lean Manufacturing supported by Value Stream Mapping (VSM) to improve production efficiency and reduce supply chain costs. This study utilizes VSM, Value Stream Analysis Tools (VALSAT), and Root Cause Analysis (5 Whys) to identify sources of waste and formulate improvement strategies. The analysis identified three dominant wastes: waiting time, product defects, and excess inventory. These were mainly caused by the lack of standardized material procedures, inadequate supporting equipment, and poor integration between the incoming inspection process and the Enterprise Resource Planning (ERP) system. To address these issues, the study proposes installing silica rolls, providing air wipers and flatness tools, developing standardized work instructions, and integrating Internet of Things (IoT) technology with the ERP system for real-time monitoring. As a result of implementing these solutions, PT X successfully reduced its defect rate from 6.23% to 1.32%, decreased lead time, and achieved notable savings in supply chain costs. The findings demonstrate that integrating Lean Manufacturing principles with VSM can effectively eliminate non-value-added activities, streamline production processes, and enhance overall competitiveness. This study reinforces the strategic value of Lean tools in continuous improvement initiatives within the manufacturing industry.

Abstract

tantangan tersendiri dalam proses produksinya, terutama dalam efisiensi waktu produksi karena metode produksi yang masih bersifat manual dan semi-manual. Penelitian ini bertujuan untuk mengidentifikasi aktivitas yang tidak bernilai tambah (Non-Value Added) dan mengoptimalkan lead time produksi pashmina eco-print menggunakan pendekatan Lean Manufacturing dengan alat bantu Value Stream Mapping (VSM). Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan teknik pengumpulan data berupa observasi, wawancara, dan dokumentasi secara langsung di lokasi produksi. Hasil dari analisis menunjukkan bahwa total lead time produksi sebelum perbaikan mencapai 9.040 menit. Setelah dilakukan perbaikan berdasarkan pendekatan Lean Manufacturing dan pemetaan ulang menggunakan VSM, total lead time berhasil dikurangi menjadi 4.677,5 menit. Efisiensi dicapai melalui pengurangan waktu tunggu, perbaikan layout kerja, eliminasi aktivitas tidak bernilai tambah, serta peningkatan koordinasi antar proses produksi. Penelitian ini menunjukkan bahwa penerapan Lean Manufacturing mampu meningkatkan efisiensi proses produksi secara signifikan dan dapat menjadi strategi yang efektif dalam industri kecil menengah berbasis seni dan budaya.

Abstract

Examining the production costs employed by PT. Lasting Prosperous Industry is the aim of this study. The research approach used in this study was qualitative research methodology. The population and sample of the study were selected to represent the societal issues that the PT firm deals with. Langgeng Makmur Industri uses field research, including observation, interviews, and documentation, as well as library research. The results of the investigation show that PT. Langgeng Makmur Industri's production cost approach does not fully utilize current theory; yet, because the company levies a 3% reserve fee, the estimation procedure is nevertheless regarded as normal.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kualitas pelayanan, persepsi harga, dan fasilitas terhadap penentuan lokasi kantin di Universitas 17 Agustus 1945 Surabaya. Penentuan lokasi kantin yang tepat menjadi faktor penting dalam mendukung kenyamanan dan kepuasan mahasiswa sebagai konsumen utama. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Sampel penelitian berjumlah 100 responden yang merupakan mahasiswa Universitas 17 Agustus 1945 Surabaya, yang dipilih menggunakan teknik purposive sampling. Pengumpulan data dilakukan melalui penyebaran kuesioner terstruktur yang telah diuji validitas dan reliabilitasnya. Data yang diperoleh dianalisis menggunakan metode regresi linier berganda dengan bantuan program SPSS, yang meliputi uji t untuk menguji pengaruh parsial, uji F untuk menguji pengaruh simultan, serta koefisien determinasi (R²) untuk mengetahui besarnya kontribusi variabel independen terhadap variabel dependen. Hasil penelitian menunjukkan bahwa kualitas pelayanan, persepsi harga, dan fasilitas secara parsial berpengaruh positif dan signifikan terhadap penentuan lokasi kantin. Secara simultan, ketiga variabel tersebut juga berpengaruh signifikan dan mampu menjelaskan sebesar 63% variasi dalam keputusan mahasiswa dalam menentukan lokasi kantin. Temuan ini mengindikasikan bahwa peningkatan kualitas pelayanan, penetapan harga yang sesuai dengan daya beli mahasiswa, serta penyediaan fasilitas yang memadai dapat meningkatkan daya tarik dan keberhasilan lokasi kantin di lingkungan kampus. Penelitian ini diharapkan dapat menjadi bahan pertimbangan bagi pengelola kantin dan pihak universitas dalam pengambilan keputusan strategis.

Abstract

In the dynamic and exciting technology startup industry uncertainty , management project device soft need approach adaptive and responsive to risk . This study explores synergy between Scrum methods and management risk in increase success project at PT XYZ, a startup that implements the Agile-Waterfall hybrid model. Qualitative methods with studies case and analysis descriptive used for digging practice management integrated risk informally in Scrum processes, such as Sprint planning and retrospectives, with support tool collaborative such as Trello and spreadsheets. The results show This synergy increases identification and mitigation risk , collaboration team , and success project in a way technical and managerial . However , the challenges Still found in the documentation risks and the roles of the Scrum Master and Product Owner that need to be considered reinforced . This study recommends development documentation more standardized risks and strengthening role the key to increasing Agile maturity and resilience projects in the technology startup environment
