Abstract

This study evaluates the ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) profile of nuciferine to assess its potential as a drug candidate. Based on in silico analysis, nuciferine demonstrates favorable oral absorption and extensive systemic distribution, including its capability to cross the blood-brain barrier into the central nervous system. Regarding metabolism, the compound acts as a substrate for CYP2D6 and CYP3A4 enzymes while serving as an inhibitor of CYP1A2 and CYP2D6, which may lead to drug-drug interactions. In terms of excretion, nuciferine displays moderate clearance values and utilizes renal transporter OCT2. However, toxicological evaluations suggest potential risks, including mutagenicity (positive AMES test), hepatotoxicity, and inhibition of hERG II potassium channels, which are associated with cardiotoxicity risks. Despite its favorable bioavailability and distribution properties, concerns about chronic toxic effects and metabolic interaction risks underscore the need for careful consideration in its development. Further research is necessary to validate its safety and efficacy for therapeutic applications.

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

As a transportation infrastructure, roads are essentially an important element in realizing economic growth and achieving healthy and dynamic social stability. Therefore, the performance of road sections needs to be considered. Road section performance can be defined as the extent to which the road is able to carry out its function. A survey conducted on 4 different days showed the performance of road sections during peak hours with a traffic volume (V) in the direction of Bangkinang-Payakumbuh of 905 vehicles/hour and in the direction of Payakumbuh-Bangkinang of 840 vehicles/hour, so that the total traffic volume on the Pasar Kuok road section is 1683 vehicles/hour. The total traffic flow (Q) on the Pasar Kuok road section is 1589.9 smp/hour. The capacity (C) on the Pasar Kuok road section is 2523.53 smp/hour. The degree of saturation (DS) of the Pasar Kuok road section is 0.61 while the V/C ratio on the Pasar Kuok road section is 0.64. That the class of side obstacles on the Pasar Kuok road section is very high (VH). It is concluded that the Sumbar - Riau road section, precisely at the Kuok market, experiences a very high saturation point on market days, namely Tuesday due to the activities of the Kuok traditional market. Because of the many vehicles parked on the shoulder of the road, street vendors (PKL) on the roadside and many people passing by on the road.

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. XYZ is a company involved in various activities related to fuel oil (BBM), such as receiving, storing, and distributing it to gasstations or Pertashop. The process of sending fuel from PT. XYZ to Pertashop is carried out using tanker trucks. One of the problemsfaced is the limited number of tanker trucks, which can cause delays in fuel delivery, so that the distribution schedule cannot be metproperly. In addition, this also reduces the time available for vehicle maintenance and increases the risk of fatigue for tanker truck drivers, which can lead to work accidents. This study aims to find an effective fuel delivery route so that travel time is shorter, so that fuel delivery to various locations can run well and on time. Using the Nearest Neighbor Method, this study can produce a more efficient solution in terms of saving distance when compared to the route currently used by the company. The proposed route with the Nearest Neighbor method has a total distance of 5268.3 km, which is a decrease of 14.49% from the current total distance. The Nearest Neighbor method can also result in savings in the number of tanker trucks, which initially used 119 trucks for 14 days, consisting of 88 tanker trucks with a capacity of 8,000 L and 31 tanker trucks with a capacity of 16,000 L. 41 tanker trucks with a capacity of 16,000 L, which has a savings in the number of tankers of 13.44%
