Abstract

The objective of this study is to overcome problems that occur in the garment industry, the company has tried to develop an agile system to increase productivity in this industry. The garment company that focusses on the production of woven bottoms and outerwear, noted that women's woven bottoms products have the highest demand throughout 2022. However, the company was unable to meet Brand demand of 3.5%. Production data shows defects in products, low quality raw materials, and unstable production processes. A modified Value Stream Mapping (VSM) methodology is use to consider all aspects of production. The results of traditional VSM and Value Stream Analysis Tools (VALSAT) analysis include current state and future state, identification of value added and non-value-added elements during the production process, as well as setting priorities to reduce waste in the production process, especially in inventory (19%), defective parts (17%), and transportation (15%). Based on the VALSAT matrix, Process Activity Mapping (33.5%), Supply Chain Response Matrix (21.6%), and Demand Amplification Mapping (15.3%) were obtained. The findings of this research are Pilot Run, which succeeded in becoming an agile and reliable system during the production process. Through the application of the methodology combined with VSM the results have improved compared to the traditional VSM method. This proves that this method is effective in overcoming takt time, cycle time, man power, and value-added ratio. Limitations of this research were also discussed, including that this research only focused on women's woven bottom products only on the production workflow. Kata Kunci: Agile System, Enhance Productivity, Garment Manufacturing, Lean Manufacturing, Value Stream Mapping.

Abstract

Industri pariwisata di Indonesia terus berkembang, didorong oleh gaya hidup lokal yang kaya, sikap ramah pengunjung, dan keragaman budaya. Namun untuk mencapai pertumbuhan berkelanjutan, integrasi teknologi dalam aspek jasa pariwisata menjadi semakin penting. Indonesia Bagian Timur khususnya Nusa Tenggara Timur mempunyai potensi besar sebagai destinasi wisata dengan keindahan seperti Taman Nasional Komodo, Labuan Bajo, dan Flores. Adanya potensi yang besar tersebut, proses pembelian tiket masuk Taman Nasional Komodo masih mengandalkan cara tradisional, hal ini menunjukkan bahwa sektor pariwisata di kawasan ini belum sepenuhnya memanfaatkan potensi teknologi digital. Pemanfaatan teknologi digital pada sektor pariwisata tidak hanya memberikan kemudahan bagi wisatawan, namun juga dapat meningkatkan efisiensi operasional dan meningkatkan daya saing destinasi serta meningkatkan kenyamanan pengunjung saat berwisata. Studi ini mengusulkan penggunaan Technology Acceptance Model (TAM) untuk menilai tingkat penerimaan teknologi di kalangan pengguna, termasuk masyarakat lokal dan wisatawan. TAM terbukti efektif dalam menganalisis faktor-faktor yang mempengaruhi adopsi teknologi oleh pengguna. Dengan penerapan TAM, penelitian ini bertujuan untuk memahami sejauh mana pengguna menerima dan bersedia mengadopsi layanan digital dalam konteks pariwisata. Dengan memahami tingkat penerimaan ini, kita dapat mengidentifikasi faktor-faktor yang mempengaruhi adopsi teknologi di sektor pariwisata Indonesia Timur. Penelitian ini menunjukkan bahwa pengunjung Taman Nasional Komodo secara umum mendapatkan sistem layanan digital yang baik. Mayoritas pengunjung (sekitar 68,6%) menunjukkan tingkat penerimaan yang tinggi, dengan kecenderungan untuk terus menggunakan layanan digital di masa mendatang dan merekomendasikannya kepada orang lain. Faktor-faktor seperti kemudahan penggunaan, manfaat yang dirasakan, dan keyakinan terhadap keandalan layanan digital memainkan peran penting dalam tingginya tingkat penerimaan. Pengunjung juga cenderung merasa puas dengan pengalaman menggunakan layanan digital di Taman Nasional Komodo.

Abstract

The aim of this research is to find the best scenario to optimize the queuing system so that it can reduce waiting time during customer service at KFC Pontianak. Queue systems are prevalent in public services. The research employs Quality Function Deployment (QFD) and Discrete Event Simulation (DES) methodologies. Alternatives generated are simulated using ARENA Simulation. 70 respondents participated in the KFC Pontianak customer questionnaire, comprising 48.6% females and 51.4% males aged between 18-45 years. The results of the questionnaire showed that 51.4% of respondents were dissatisfied with the speed of service at KFC Pontianak. Customer needs identified through QFD include service speed, order accuracy, ease of use, customer satisfaction, queue comfort, food quality, and payment integration. Analysis reveals three queue system scenarios, two of which propose improvements. The second scenario involves 2 cashiers and 2 self-service cashiers. Self-service allows customers to order by scanning a QR code integrated with the service provider's application. Arrival type employs an exponential distribution with an average of 61 seconds, unlimited max arrival, and first creation with a value of 0. In self-service, there is a value difference of 1 and a standard deviation of 0.2. Simulation results indicate that 51 customers choose cashier 1, 41 choose cashier 2, 39 opt for self-service cashier 1, and 53 prefer self-service cashier 2. The total successfully served customers are 94, with a success rate of 51%. In the third scenario involved 4 self-service cashiers only, the values of 1 and standard deviation of 0.2. The total number of successfully served customers is 173, with a success rate of 80%. In conclusion, this research offers valuable insights for optimizing KFC Pontianak's queue system, addressing customer dissatisfaction with service speed. The proposed scenarios, especially those involving self-service options, demonstrate potential improvements in customer satisfaction and operational efficiency.

Abstract

Penelitian ini bertujuan mengoptimalisasi layanan kasir di Kafe Hagami Tangerang dengan memberikan rekomendasi terhadap sistem antrian pada saat peak time. Metode penelitian menggabungkan Quality Function Deployment (QFD) dan Discrete Event Simulation (DES), yang akan diimplementasikan melalui perangkat lunak simulasi ARENA. Hasil awal dari kuesioner dengan 100 responden, 56% perempuan dan 44% laki-laki, usia 18-45 tahun, menunjukkan 53% responden tidak puas dengan kecepatan layanan di kafe tersebut. Customer needs yang diidentifikasi melalui QFD menyoroti Pelayanan Cepat dan Opsi Pemesanan & Pembayaran Digital sebagai prioritas utama dengan masing masing bobot sebesar 19%. Hasil analisis dengan software ARENA selama peak time pada jam 18.00-21.00 menunjukkan bahwa Skenario 3, yang melibatkan penggunaan barcode pada setiap meja, berhasil melayani 85 pelanggan dengan tingkat keberhasilan 50%. Rekomendasi ini diharapkan dapat meningkatkan efisiensi layanan kasir di Kafe Hagami Tangerang pada jam sibuk.
