Abstract

PT X yang berlokasi di Padang merupakan perusahaan yang bergerak di bidang produksi pakan ternak, didukung oleh gudang bahan baku yang berperan krusial dalam efisiensi operasionalnya. Penelitian ini digagas karena masih terdapat inefisiensi pada tata letak gudang saat ini, khususnya penempatan bahan baku yang kurang tepat dan tidak dikelompokkan berdasarkan jenisnya. Tujuan utama penelitian ini adalah untuk meningkatkan efisiensi pengambilan bahan baku dan mengoptimalkan tata letak gudang dengan cara mengatur bahan baku berdasarkan klasifikasi dan frekuensi pemakaiannya. Metode shared storage digunakan untuk memungkinkan alokasi penyimpanan yang fleksibel, sehingga bahan-bahan dengan karakteristik yang berbeda dapat ditempatkan di area yang sama berdasarkan prioritas pemakaian. Pengumpulan data dilakukan melalui wawancara dengan petugas gudang dan pengamatan langsung terhadap aliran material dan praktik penyimpanan. Hasil penelitian menunjukkan bahwa bahan baku yang sering digunakan disimpan terlalu jauh dari area produksi, sehingga mengakibatkan waktu pengambilan yang lama dan penumpukan. Tata letak yang diusulkan merekomendasikan reposisi bahan baku tersebut lebih dekat dengan pintu masuk produksi, dengan jarak optimal berkisar antara 16,5 hingga 125,5 meter. Desain ulang tata letak ini bertujuan untuk mengurangi waktu penanganan material dan meningkatkan efisiensi gudang secara keseluruhan melalui pengaturan yang sistematis berdasarkan jenis dan frekuensi pemakaian.

Abstract

Pharmacy services are a critical support unit within the healthcare system of hospitals, particularly for BPJS (Indonesia's National Health Insurance) patients, whose numbers continue to rise. However, pharmacy service processes often face several challenges, including prolonged waiting times, inefficient queues, lengthy initial registration procedures, and drug stock mismatches. This study aims to analyze and propose performance improvements in pharmacy services for BPJS patients at XYZ hospital using a Lean approach. The method employed in this research is Value Stream Mapping (VSM) to map out the service flow and identify waste. Data were collected through direct observation, interviews, and documentation, covering initial process mapping, service time for each process activity, and the number of prescriptions served monthly. The analysis revealed several non-value-adding activities affecting service efficiency, such as high waiting times, inefficient staff movements, drug stockouts, and disorganized drug storage. After implementing improvements based on Lean principles, average patient waiting time decreased, with compounding drug service time reduced from 23 to 20 minutes and non-compounded drug service time reduced from 17 to 14 minutes. The study concludes that applying the Lean method can significantly enhance the performance of pharmacy services. Strategic recommendations are also provided to maintain work efficiency and ensure continuous quality improvement at XYZ Hospital.

Abstract

The pharmaceutical industry faces increasing pressure to maintain efficient supply chain operations amid dynamic market conditions. This study aims to identify the most accurate sales forecasting method to optimize pharmaceutical logistics and support the competitive advantage of PT “X” in producing Black Cough Syrup 100 ml. Using historical monthly sales data from August 2023 to January 2025, the study applies four quantitative forecasting techniques: Single Moving Average (SMA), Weighted Moving Average (WMA), Single Exponential Smoothing (SES), and Linear Regression. Forecast accuracy is evaluated using Mean Absolute Deviation (MAD) and Mean Absolute Percentage Error (MAPE). The results reveal that the 3-period SMA method yields the lowest forecast error (MAD: 954; MAPE: 21.09%) and is the most suitable model for the case. These findings highlight the strategic importance of integrating forecasting methods into pharmaceutical logistics to improve production planning, reduce stockout risks, and enhance customer satisfaction. By adopting accurate forecasting tools, PT “X” can strengthen interdepartmental coordination, improve inventory turnover, and build a sustainable competitive edge in the pharmaceutical market.
