Abstract

Puyuh merupakan jenis burung yang tidak dapat terbang, ukuran tubuh relatif kecil, berkaki pendek dan dapat diadu. Burung puyuh dalam Bahasa asingnya disebut Quail, merupakan bangsa burung (liar) yang pertama kali diternakkan di Amerika Serikat pada tahun 1870, dan terus dikembangkan ke penjuru dunia. Sementara itu di Indonesia puyuh mulai dikenal dan diternak semenjak akhir tahun 1979. Kini mulai bermunculan di kandang-kandang ternak yang ada di Indonesia. Usaha kecil budidaya dapat menjadi alternatif yang sangat tepat untuk memaksimalkan pendapatan rumah tangga. Budidaya puyuh pada skala rumah tangga sangat dianjurkan karena perekonomian Indonesia yang belum stabil. Peluang usaha ternak puyuh sangat menguntungkan sementara permintaan telur puyuh dari tahun ke tahun semakin naik. Telur puyuh terkenal karena mengandung banyak gizi, diantaranya adalah vitamin, mineral, bakteri salmonela dan tidak mengandung protein atau lemak jahat. Selain itu, telur burung puyuh juga memiliki citra rasa yang lezat sehingga dapat dijadikan sebagai usaha kuliner yang menguntungkan. Daging puyuh ternyata juga diminati oleh masyarakat, banyak restoran yang saat ini menyediakan menu dengan bahan dasar puyuh. Biasanya puyuh yang dijual untuk diambil dagingnya adalah jenis burung afkiran. Puyuh afkiran biasanya kurang baik untuk bertelur sehingga kemudian dijual untuk dimasak sebagai menu masalan di beberapa warung makan atau restoran. Untuk meningkatkan budidaya puyuh petelur di Desa Rajamandala Kulon Kecamatan Cipatat kabupaten Bandung Barat dilakukan upaya menggulirkan modal yang efisien dan efektif dalam bentuk budidaya Puyuh Petelur. Pelaksanaannya dilakukan secara terintegrasi mulai dari penetasan telur, pembesaran, penjualan telur puyuh, daging puyuh, kuliner puyuh, pembuatan pakan puyuh, serta pemanfaatan kotoran puyuh. Dengan pengalaman tersebut diharapkan akan lahir para wirausaha profesional dalam bidang ternak burung puyuh yang terintegrasi terintegrasi. Program ini merupakan salah satu usaha revitalisasi pengembangan peternakan puyuh disamping kegiatan lainnya yaitu pembentukan kelompok dan peningkatan kualitas sumber daya manusia di desa tersebut.

Abstract

Facility design refers to the method of organizing factory facilities to support the efficiency of the production process and the effectiveness of production results. This improvement is done by updating the design of previous facilities or designing a complete facility that has not yet been built. In designing this facility design system, Soft System Methodology (SSM) was used. SSM is a structured approach to information system development that is used to understand the problem thoroughly, design conceptual models, assess the feasibility and desired changes, and then implement them into reality. In this research, SSM proved to be a highly effective framework for designing facility design systems in the context of the clothing convection industry. SSM includes abstract problem mapping, needs analysis of stakeholders involved in the system, CATWOE analysis, depiction of desired and undesired inputs and outputs through IO Diagram, expression description through Rich Picture, and grouping of core activities with Conceptual Modeling. The result of this research is a description that is traceable to the problem situation that exists in the facility design system so that it can know and master the involvement of actors in the system and the relationship between actors and activities that take place.Keywords – Clothing Convection Industry, Facility Design, Soft System Methodology(SSM), System Approach.

Abstract

PT. XYZ is a manufacturing company engaged in the automotive sector by producing various automotive components. Based on the results of observations and interviews at PT. XYZ, it is known that there is a shortage of stock, so that customer or consumer requests are not fulfilled at each existing distribution center (DC). Based on the problems that occur, the research result suggestions for the best forecasting method based on the time series plot of each DC request processing using the Distribution Requirement Planning (DRP) method. In addition, with the DRP method, there is additional stock. The company still has remaining stock so it can still meet customer demand for each DC, and the product distribution process runs more regularly if any defective product should be replaced. Based on research results, the DRP method is able to minimize the risk of unfulfilled demand due to product defects.

Abstract

Effective inventory management is crucial for companies distributing perishable products. PT XYZ requires a precise control method to optimize inventory and minimize losses. This study aims to determine the top 5 priority products, identify the best forecasting method with the smallest error and analyze the implementation of Single Order Quantities (SOQ) in inventory management. Using primary and secondary data collected from 1 January 2021 to 4 April 2022, the study employed ABC Analysis to categorize products, followed by demand forecasting using Single Moving Average, Single Exponential Smoothing, and Fuzzy Time Series to select the most accurate method. Inventory planning was then carried out using SOQ to enhance efficiency. Among 196 vegetable types, 5 were identified as the highest priority: Birdseye Chili Pepper (1 kg), Red Cayenne Pepper (1 kg), Birdseye Chili Pepper (Min. 5 kg), Local Cucumber (1 kg), and Bulk Green Paprika. The SOQ method enabled optimized inventory strategies, ensuring product availability while minimizing excess stock. This research provides practical insights for effective inventory planning, particularly for businesses handling perishable goods.Keywords - Demand Planning, Fuzzy Time Series, Inventory Planning, Perishable Product, Single Order Quantity.

Abstract

Polyester yarn is a key raw material in textile manufacturing due to its durability and affordability. PT ABC relies on external suppliers for polyester yarn, making inventory management crucial for production efficiency. However, the company's current ordering approach has led to occasional stock shortages, impacting operations. This study develops an inventory control model using the Economic Order Quantity (EOQ) method, incorporating safety stock and reorder point calculations to minimize stockouts and reduce inventory costs. Additionally, Artificial Neural Networks (ANN) are used to forecast demand for 2022, improving estimation accuracy. Based on historical demand data from 2019 to 2021, the EOQ method lowers inventory costs compared to the company’s approach, achieving efficiency gains of 19%, 12%, and 29%, saving IDR45,745,000, IDR23,735,000, and IDR98,020,000, for each respective year. The ANN model utilizing the TrainLM training function achieves the lowest Mean Squared Error (MSE) of 0.063528 and forecasts a total raw material requirement of 2,510,628 kg for 2022. The EOQ value for 2022 is set at 44,817 kg, with safety stock and reorder point levels of 8,438 kg and 29,360 kg, respectively.Keywords – Artificial Neural Network, Economic Order Quantity, Inventory, Reorder Point, Safety Stock.
