Abstract

PT.XYZ is a company engaged in the logistics sector, which has several lines of business. PT.XYZ is facing issues with trailer truck delays in the import distribution activities of one of its customers. The methods that can be used to address this issue is the application of Lean Six Sigma with the DMAIC approach. This research aims to apply Lean Six Sigma principles to improve the efficiency of import distribution activities using several tools such as Value Stream Mapping, fishbone diagrams, and 5W+1H. The research results show that the sigma value is 2.08. Some of the causes of the problems are due to several factors, namely human resources, methods, machines, and the environment, which are then improvised with questions about the problems that occurred, when, where, why, who, and how the problem could occur. The control stage is carried out by creating a form aimed at controlling the improved process.

Abstract

PT. XYZ is a trading company engaged in the multinational distribution of packaging products. To support the sustainability of its operations and performance, PT. XYZ is required to select vendors that can optimally meet its needs. However, in practice, the company does not yet have a standardized method or clear criteria for vendor selection, relying solely on price considerations. This condition may lead to inaccurate decision-making, which can negatively affect company performance. This study aims to evaluate the paper packaging vendor selection process at PT. XYZ using the Analytical Hierarchy Process (AHP) method. The results indicate that price is the most dominant criterion in the decision-making process, with a weight of 0.377. Among the five vendor alternatives analyzed, Vendor B was identified as the most suitable choice, with the highest priority weight of 0.232. These findings are expected to serve as a reference for the company in adopting a more structured and objective vendor selection process in the future.

Abstract

Kemampuan pengadaan sebuah perusahaan di dalam manajemen rantai pasok berdampak pada kualitas kemampuan kerja perusahaan, perkembangan produk, reaksi konsumen, dan kemampuan anggaran perusahaan. Dalam pelaksanaannya, pengadaan terdiri dari berbagai bentuk dan berbagai tahap yang memungkinkan terjadinya pemborosan (waste) sepanjang aktivitas pengadaan yang memengaruhi efisiensi dan efektivitas dari proses pengadaan itu sendiri. Penelitian ini bertujuan untuk mengisi celah kekosongan terkait perbaikan terhadap proses pengadaan melalui pendekatan lean yang dapat menyederhanakan proses dan mengurangi aktivitas yang tidak memberikan nilai tambah dengan hasil yang diharapkan dapat memberikan kontribusi sebagai panduan bagi perusahaan dalam mengoptimalkan alur rantai pasoknya agar lebih sesuai dengan kebutuhan perusahaan itu sendiri maupun kebutuhan pelanggan. Melalui lean procurement process ditemukan beberapa aktifitas yang tidak memberikan nilai tambah serta bottleneck yang menjadi penghambat jalannya proses pengadaan, dengan potensi pemborosan di dominasi oleh pemborosan waktu dan pengulangan alur kerja. Dengan adanya analisis menggunakan pendekatan lean terhadap proses pengadaan ini dapat memberikan gambaran bagi perusahaan untuk membentuk proses pengadaan yang lebih optimal.

Abstract

Inefficient material distribution at PT XYZ causes production delays in tactical vehicles and increases operational costs. This study aims to identify waste in the material distribution process using the Lean Logistics approach with the help of Value Stream Mapping (VSM) and Process Activity Mapping (PAM) tools. The analysis shows that out of a total distribution time of 6,835 minutes, only 273 minutes (4%) are value-added (VA) activities, while the remainder consists of non-value added (NVA) and necessary non-value added (NNVA) activities. These findings highlight the dominance of wasted time due to delays, transportation, and inefficient storage. The study recommends continuous improvement through lean tools and the implementation of digital technologies to accelerate distribution flow and reduce waste. This approach can enhance overall logistics efficiency and company productivity.

Abstract

A slow and inefficient inbound process is a major challenge in the warehouse operations of PT DE, a company in the FMCG sector. This study aims to optimize the inbound process through the implementation of Lean Logistics. The method used is a quantitative approach by combining Lean Six Sigma through the DMAIC cycle and Kaizen principles through the PDCA cycle. Observations show that most inbound activities fall under Necessary Non-Value Added (NNVA), such as manual inspections, data entry, and documentation, accounting for up to 93% of the total process duration. Root cause analysis was carried out using Value Stream Mapping and Fishbone Diagram. Improvement solutions include implementing barcode/RFID technology, automated conveyors, employee training, and standardized procedures. After implementation, there was a significant increase in the speed and accuracy of goods receipt. Control was maintained through regular audits and a digital monitoring system. The application of Lean Logistics proved effective in reducing waste, increasing efficiency, and supporting continuous improvement in the FMCG warehouse environment

Abstract

UMKM merupakan salah satu sektor penting dalam pertumbuhan ekonomi Indonesia, termasuk di Kota Bandung. Salah satu tantangan yang dihadapi adalah tingginya tingkat pemborosan produksi, seperti yang terjadi pada UMKM Takomi. Penelitian ini bertujuan untuk mengidentifikasi dan mengurangi pemborosan dalam proses produksi takoyaki dengan menerapkan metode Lean Six Sigma menggunakan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control). Metode yang digunakan adalah deskriptif kuantitatif melalui observasi, pencatatan produksi harian, perhitungan DPMO, serta analisis akar masalah dengan diagram fishbone dan teknik 5 Whys. Hasil penelitian menunjukkan bahwa pemborosan utama terjadi pada proses penakaran adonan yang tidak sesuai dan proses penggorengan yang tidak optimal. Melalui pembuatan SOP, penyediaan alat bantu, pelatihan, dan evaluasi rutin, pemborosan dapat ditekan secara signifikan. Kesimpulannya, penerapan Lean Six Sigma efektif dalam meningkatkan efisiensi produksi dan kualitas produk di UMKM Takomi.

Abstract

Tujuan: Penelitian ini bertujuan untuk mengidentifikasi akar penyebab dominan dari cacat kemasan beras selama proses distribusi, serta merancang dan memvalidasi usulan perbaikan yang efektif menggunakan kerangka kerja Six Sigma DMAIC. Desain Penelitian dan Metodologi: Penelitian ini menggunakan pendekatan kuantitatif dengan desain studi kasus pada proses distribusi beras PT. XYZ (Januari-Juni 2024). Analisis data dilakukan melalui siklus DMAIC, memanfaatkan alat seperti Diagram Pareto, Failure Mode and Effects Analysis (FMEA), dan Simulasi Monte Carlo untuk validasi solusi. Hasil dan Pembahasan: Kinerja proses awal berada pada level 4.0 Sigma (DPMO 6.125) dengan kondisi tidak stabil. Cacat dominan adalah "Jahitan Penutup Lepas" (94,85%). Analisis FMEA mengungkap tiga akar penyebab kritis dengan RPN tertinggi (560): ketiadaan Standar Operasional Prosedur (SOP), pelatihan formal, dan alat bantu penanganan material. Implikasi: Implementasi usulan perbaikan terpilih (pembuatan SOP, demonstrasi oleh pengawas, dan pengadaan alat bantu) diproyeksikan mampu meningkatkan kapabilitas proses hingga level 4.5 Sigma (DPMO 1.224). Hasil ini memberikan kerangka kerja praktis bagi perusahaan logistik untuk mengurangi kerugian dan menegaskan relevansi DMAIC untuk mengatasi masalah kualitas yang bersumber dari faktor manusia dan metode dalam lingkungan operasional yang dinamis.

Abstract

Supplier X in Lembang faces distribution efficiency issues due to a conventional delivery system that results in long travel distances and high operational costs. This study aims to optimize the distribution system through the implementation of a Milk Run System based on Lean Logistics and the Vehicle Routing Problem (VRP) method using the Nearest Neighbor algorithm. This case study involves the delivery of cabbage to five local markets with a total demand of 1,000 kg using a single pick-up vehicle. The analysis stages include data identification, distance matrix development, savings calculation, and route simulation. The results show a reduction in travel distance from 101.8 km to 41.3 km, travel time to 99.12 minutes, and distribution cost efficiency from Rp326,800 to Rp267,700 per day. This study recommends the implementation of an integrated lean-based distribution system as a strategy to enhance logistics efficiency and operational sustainability.
