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

PT X is a pharmaceutical manufacturing company producing cosmetics, household health supplies, medicines, and quasi-drugs. During the internship period of 8 months, various aspects of agro-industrial logistics were observed, including demand planning. The study focused on addressing recurring issues of stockouts of talcum powder, specifically Salisil Talk Wangi 45 grams, caused by inaccurate forecasting and manual estimation methods. To resolve this, the Double Moving Average method was applied to forecast demand for the product. The results showed that for the Blue variant of Salisil Talk Wangi 45 gr, the forecasting error was MAD = 1.236 and MAPE = 7%. For the Yellow variant, MAD = 1.109 and MAPE = 7%, and for the Green variant, MAD = 1.109 and MAPE = 8%. These results suggest that the Double Moving Average method is effective in supporting raw material planning for better production continuity.
