Abstract

Currently the problem of Optical Distribution Point (ODP) infrastructure is important in fiber to the home (FTTH) network access because ODP infrastructure development is no longer dependent on demand, so placing ODP manually without a systematic method can cause an increase in the value of optical fiber attenuation. on the length of the cable and cause the cable distribution to be irregular. This study aims to optimize the placement of ODP devices in PT BCV's FTTH network by using the Traveling Salesman Problem (TSP) scheme with the genetic algorithm (GA) approach and using hybrid GA, testing is carried out using Matlab software. Testing with development using Hybrid GA gets the best path with a fitness value of 28.6457 and a computation time of 89.93 seconds.

Abstract

This research aims to design an ergonomic toddler dining chair that meets the needs of safety, comfort, and usability for families, restaurants, and daycare centers in Padang City. The study identifies deficiencies in existing products and proposes solutions that suit user preferences and ergonomic standards. This research utilizes a mixed-method approach, starting with the Kano model to classify user needs into categories such as "must-have," "performance," and "attractive" features. These needs are then translated into technical specifications using the Quality Function Deployment (QFD) methodology. Data were gathered through questionnaires distributed to families with toddlers and toddler chair providers. The analysis involved validity and reliability tests using SPSS, ensuring the responses were consistent and accurate. The House of Quality (HoQ) matrix was employed in two phases to map customer needs to technical and design characteristics. Anthropometric data were incorporated to ensure that the design meets ergonomic requirements. This research contributes to the theory of ergonomic product development by demonstrating the integrated use of the Canoe and QFD models to prioritize and address user needs effectively. This research offers a solid foundation for developing an ergonomic toddler feeding chair that improves safety and comfort for toddlers, reduces the risk of musculoskeletal disorders, and improves usability for parents and service providers. The findings also emphasize the importance of anthropometric data in creating products tailored to specific user groups. The research made a new contribution to toddler furniture design by developing a dining chair that integrates important ergonomic features, including adjustable height, folding mechanism for portability, secure and comfortable backrest, and durable and easy-to-clean materials. This design addresses the concerns of users identified through comprehensive data analysis, offering a safer and more convenient product compared to the options on the market. In addition, this research framework can be a reference for future studies in developing ergonomic products.

Abstract

Indonesia is listed as the second largest contributor to plastic waste in the world. The problem currently faced is the increasing amount of plastic waste which is one result of the business processes of companies using plastic packaging or plastic packaging manufacturers, one of the plastic packaging waste that comes from cooking oil packaging. The method to solve the problem of processing cooking oil packaging waste carried out in this study is to modify the existing system into a reverse logistics system. Currently, cooking oil companies have not implemented reverse logistics to reduce plastic packaging production. The reverse logistics system applied in this study is to modify cooking oil packages into packages that can be used repeatedly. The reverse logistics system that is applied is then modeled linerly to find out the minimal costs in implementing reverse logistics for the packaged cooking oil. Based on the development of the packaged cooking oil waste management model, it is known that the results of determining the model solution with the linear programming model are the minimal costs for reverse logistics of packaged cooking oil. The model is designed to do a sensitivity analysis by making changes to the reverse logistics cost parameters, changes in the reverse logistics cost parameters resulting in changes to the results that are directly proportional. The designed model is implemented using PT. XYZ which has a similarity with the designed system.

Abstract

The definition and function of inventory management reveal the importance of modern industry in formulating policies that regulate the supply of raw materials, semi-finished products, and finished products. Unfortunately, most companies fail to consider the characteristics of their raw materials when determining inventory strategies. Raw materials that are perishable are those that consider their service life and storage time. Inventory management plays a crucial role in supply chain management, especially for perishable raw materials, such as food products. PT X, a food business in Padang, experienced difficulty in meeting the demand for rendang products due to a lack of raw materials. Therefore, this study aims to develop an inventory management model that takes into account the perishable raw materials' expiration time. The model development consists of three stages: model development design, inventory model formulation, and model testing. The proposed model resulted in a storage time interval of five days and an optimal order quantity of 34 kg of meat with a safety stock of 14 kg. Implementing this model led to lower total inventory costs for PT X than the actual conditions of the company. The total inventory cost obtained using this model is Rp279,797,822. This study emphasizes the importance of considering the characteristics of raw materials in determining inventory strategies to optimize inventory management effectively and efficiently. The study's findings can serve as a reference for other food businesses encountering similar inventory management challenges in the perishable food industry.
