Abstract

UMKM sebagai penyumbang Produk Domestik Bruto (PDB) nasional memiliki peran penting dalam pemulihan ekonomi Pasca Pandemi Covid-19. Perkembangan dan juga peningkatan kemampuan UMKM agar dapat bersaing di pasaran perlu difasilitasi dan dibantu. PT Nirwana Unggul Restu tercatat sebagai UMKM yang baru didirikan dan masih belum memiliki media promosi yang memadai. Oleh karena kegiatan pengabdian Masyarakat ini berfokus pada implementasi pengembangan media pemasaran dan digitalisasi pemasaran di PT Nirwana Unggul Restu. Kegiatan ini dilakukan selama kurang lebih 4 bulan dari mulai bulan Agustus hingga November 2023 dengan jumlah anggota pelaksana tiga orang dosen dengan bidang program studi yang berbeda. Adapun beberapa teknologi yang dihasilkan melalui media digital, yaitu diantaranya logo usaha, label produk, mockup packaging produk, dan media promosi melalui Instagram bisnis.

Abstract

This research was conducted at PT Tri Sapta Jaya, a medical equipment distributor company. The product distribution to consumers was inefficient due to using traditional methods. The division of regions and determination of delivery routes was based on districts and cities. The existing delivery method faced various challenges, including delivery delays and inefficient routes. This inefficiency results in potential financial losses for the company in terms of delivery costs. To assist the company in improving delivery efficiency, this research focuses on determining vehicle routes considering vehicle capacity (Capacity Vehicle Routing Problem). In solving and searching for solutions, the research uses Simulated-Annealing algorithm. The algorithm generated an initial solution randomly and improved the solution by changing the positions of consumers within a route and switching positions of consumers between routes to obtain the best solution. The computation time of the developed Simulated Annealing algorithm was quite efficient, taking only 2 seconds for 25 consumers. Based on the data from PT Tri Sapta Jaya, the best solution obtained was 615,319. This result was achieved using the Simulated Annealing algorithm with the parameters T0 = 100,000, Ta = 1, and α = 0.9.

Abstract

PT Nandya Karya Perkasa is a manufacturing company that produces motor vehicle spare parts. PT Nandya Karya Perkasa supplies its products to several automotive companies. The company faces issues with its inventory due to frequently fluctuating demand, often leading to order cancellations. Data from the past three months shows the company had to cancel approximately 19% of orders. This issue arises because of the limitations of the previously used application. Some crucial data, such as stock levels, which should support decision-making, is still missing, as the existing system only focuses on recording goods' inflows and outflows. This study aims to propose improvements to the use of the Inventory Management System application to facilitate the planning department in planning the production process, ensuring the availability of goods in the warehouse to meet all consumer demands. The method used to address this problem is a web-based application for monitoring goods, which can provide feedback for production planning improvements in case of demand changes. The system is developed using the Prototype method. A two-month trial has shown a reduction in order cancellations to 11%.

Abstract

This study aims to provide an overview of the concept of Value Stream Mapping and its significance in process improvement. It highlights the key steps involved in creating a VSM and emphasizes its role in identifying and addressing various types of waste, such as waiting time, unnecessary movement, and rework. By mapping the current state of a process, organizations gain insights into its inefficiencies and areas for improvement. Furthermore, the importance of developing a future state Value Stream Map that outlines the desired state of the process after implementing improvements. It emphasizes the need for continuous monitoring and evaluation to ensure sustained progress and ongoing optimization. Overall, Value Stream Mapping offers organizations a systematic approach to analyze, optimize, and enhance their processes. By visualizing the value flow and identifying opportunities for improvement, businesses can achieve higher levels of efficiency, reduced costs, improved quality, and ultimately deliver greater value to their customers. The calculation and analysis explained that the total processing time was 105.8 minutes and the total lead time was 47 minutes resulting in a non-value added (NVA) of 34 minutes. If the converted into a process percentage form, it is 32% of the total time spent on operational air freight.

Abstract

Service quality is crucial for companies in the service sector, directly impacting customer satisfaction. PT BLI, a company offering TPS warehouse rental services, is facing issues with a low influx of containers and customer complaints. This research aims to analyze the service quality at PT BLI's warehouse storage section using the Servqual method, which encompasses five quality dimensions and 24 attributes, followed by Importance Performance Analysis (IPA) to identify attributes that require immediate improvement. The Servqual analysis revealed that 10 attributes of PT BLI's service quality do not meet customer expectations. Through IPA, five attributes were identified as high-priority for improvement: the safety of goods in the warehouse (gap of -0.07), the informativeness of employee service regarding activity updates (gap of -0.14), the speed of employees in processing goods in and out of the LCL warehouse (gap of -0.34), the ability of employees to understand consumer needs (gap of -0.01), and the communication skills of employees in providing excellent service (gap of 0.32). Addressing these critical service quality gaps will help PT BLI enhance customer satisfaction, reduce complaints, and potentially increase the number of incoming containers, positively impacting the company's standing in the warehouse rental industry.

Abstract

PT Sinar Mas Andhika menghadapi masalah dalam proses pengiriman barang. Ketidakseimbangan rute berdasarkan jam aktual dan jumlah barang yang dikirim berbeda-beda. Hal ini menyebabkan ada armada yang kembali terlalu cepat, sementara yang lain terlalu lama. Beban kerja operator pengiriman yang menjadi tidak seimbang dan keterlambatan pengiriman sering terjadi. Penelitian ini bertujuan untuk menyeimbangkan rute dan mengoptimalkan jumlah armada yang digunakan dalam pengiriman barang di PT Sinar Mas Andhika dengan mempertimbangkan batasan jam aktual pengiriman. Permasalahan Vehicle Routing Problem (VRP) ini merupakan varian Heterogeneous Vehicle Routing Problem (HVRP) karena kapasitas armada pada PT Sinar Mas Andhika yang berbeda-beda. Dalam menyelesaikan permasalahan ini maka dipilih Metode algoritma sweep untuk membentuk kelompok rute dengan mengalokasikan 19 titik tujuan berdasarkan koordinat polar, menggunakan aplikasi GeoGebra sebagai alat bantu. Hasil penelitian menunjukkan bahwa rute baru yang dihasilkan berjumlah 5 rute pengiriman, memungkinkan perusahaan untuk menggunakan hanya 5 armada. Usulan perbaikan ini menghasilkan penghematan waktu sebesar 17,32%, penghematan jarak tempuh sebesar 20,47%, dan penghematan biaya pengiriman sebesar 21,51% atau Rp 46.136,50 per hari. Selain itu, utilisasi kapasitas kendaraan meningkat karena pembagian muatan yang lebih merata, dengan hanya 2 kendaraan mengalami pengurangan muatan yang sudah dialokasikan ke armada lainnya. Implementasi usulan ini diharapkan dapat meningkatkan efisiensi operasional PT Sinar Mas Andhika, mengurangi biaya, dan meningkatkan kepuasan pelanggan dengan layanan pengiriman yang lebih andal dan tepat waktu.
