Abstract

The TPS Reduce, Reuse and Recycle Tenggilis Mejoyo faces a problem with waste residue levels of 58.61%, far above the ideal target of 30%. This research develops an automated waste sorting device using the Quality Function Deployment (QFD) approach to optimize the sorting process. The research methodology employs four QFD phases from Voice of Customer to production planning. A prototype measuring 40x10 cm with a conveyor speed of 10 cm/s was developed based on high-priority technical responses. Testing was conducted with 5 repetitions using 150 mixed samples of plastic and paper. Results showed an overall accuracy of 83.95% with details of 85.3% for plastic and 82.6% for paper/cardboard. Actual capacity reached 13 sorts/minute for plastic and 21 sorts/minute for paper. Implementation of the device increased accuracy from 65% to 84% (19% improvement). The automation system with YOLO algorithm proved effective in improving sorting effectiveness and contributing to waste residue reduction at the 3R TPS.

Abstract

The development of internet brings great influence in business management, especially in supply chain. Transaction conducted through the internet in supply chain known e-fulfillment, is an integrated process from receiving customer order, managing transaction, warehousing, managing transportation, communicating, with customer using media of information technology. Online sales concept opens up the researchers to conduct research on online sales and offline sales simultaneously, known Dual Channel Supply Chain (DCSC). One category of products that are sold using this structure is fashion product. However, selling fashion product using DCSC structure it still has shortcomings and challenges. Due to customer can not make a selection, viewing and researching product and quality inspaction product dierctly. Based on this, some enterprises provide product warranty sales system offered. Warranty as a guarantee given to customer to provide security and comfort for making purchases. Warranty gives impact on price of product, both online and offline. This leads to the need to do a calculation the optimum price considering money back warranty. Optimum price obtained in the model demand function using quadratic programming adressing the objective function in the form profit maximum in individual channel (Pw, Ps dan Po) as well as whole profit in DCSC by considering the value of money back warranty (g). The result obatained is optimum price for two scenarios. There are optimum price in individual channel without money back warranty and optimum price in online channel with accomodate money back warranty. Keywords—dual channel supply chain (DCSC); money back warranty; optimization.

Abstract

Residential high-rises are unique properties that differ from landed properties such as bungalows or terrace houses. They are unique insofar as, after the properties have been occupied, facilities must be jointly managed by residents. The continuous growth of high-rise residential buildings specifies that there is a need for effective ownership and property management system to instill a valuable living experience among high-rise residents in this country. Looking at this scenario, this research takes an initiative to develop a mobile application that supports streamline information with assistive features to improve communication and information sharing for high-rise residential management in Malaysia. This aim is achieved by answering three research objectives, including identifying user requirements, designing the application prototype and developing the artefact and evaluating the artefact. The study was conducted together with LT Sdn Bhd, the property management company responsible in managing and maintaining property related matters of Seroja Apartment. An adopted conceptual framework for property management based on the sustainable indicator dimensions for property management and applicable features from existing mobile application to develop the artefact has been proposed. The conceptual framework was proposed based on literature review and nature of work observed on site. Lastly, the study successfully validated the proposed adopted framework against the artefact, the MyLT mobile application.

Abstract

The increasing activity of container handling in depots requires improvements in service efficiency, particularly in inbound and outbound processes that often experience long truck queues. PT Seacon Bintang Sejahtera Surabaya faces delays that exceed its Key Performance Indicator (KPI) of 35 minutes. This study aims to analyze the performance of the queueing system and propose improvements to minimize service time using Arena simulation software. Primary data were obtained through direct observation, including truck arrival times, service start times, and service durations. The simulation model was validated to match real operational conditions, followed by testing several improvement scenarios such as additional servers and optimized service flow. The simulation results indicate that the proposed scenarios significantly reduce waiting times compared to the existing system, providing a basis for improving operational performance in container depot services
