Abstract

Ship transportation is a very important tool for the sustainability of the maritime industry. Considering the importance of using ships, regular repairs are needed on ship components, one of which is the roller fairlead. Repairs to the roller fairlead on the ABC ship, which were originally only scheduled for 7 working days, were delayed by up to 38 working days. Therefore, this research aims to analyze the factors causing delays in the roller fairlead repair process on ABC Ships carried out by PT XYZ. Data collection was carried out by conducting direct interviews and distributing questionnaires to related parties. The data that was collected was processed using the Kaiser-Meyer-Olkin (KMO) and Root Cause Analysis (RCA) methods to identify and analyze the root causes of delays. The results of the analysis show that the main factor causing delays is a lack of labor allocation with a mean value of 4.38. Based on the results of this analysis, suggestions for improvement are given using the fishbone diagram tool. In this way, PT XYZ is expected to be able to increase work effectiveness, so that similar incidents do not happen again in future projects

Abstract

The purpose of this research is to analyze the effectiveness level of the service system in the commercial livestock feed loading process at PT. JKL and to provide improvement suggestions to enhance the performance of the queue system in the livestock feed loading process. The queuing system problem is solved by implementing the queuing theory concept using the multiple channel query system (M/M/S) method. The use of the M/M/S method can analyze the performance of the queuing system in the livestock feed loading process, which provides 6 service servers during the period from 08:30 to 11:30 and 1 queue line. This research uses primary data consisting of the number of vehicle arrivals and the number of vehicles that have been served. From the data processing results, the highest server utilization rate of 40.9% was obtained during the time period between 08:30-09:31 with 3 vehicles in the system. The probability of no vehicles in the system is 8.54% with an average time of vehicles in the system being 5.522 minutes. From these results, suggestions can be made to improve the performance of the queue system by adding forklift operator staff and increasing the loading speed of the contract workers.

Abstract

Urban aquaculture, like urban farming, entails using aquaculture technology to transform tiny, previously unutilized pieces of land in highly inhabited metropolitan areas into a useful area. Urban aquaculture, in broad terms, can be defined as the fish farming on small plots of land. Depending on the sort of consumable fish commodity to be grown, urban aquaculture can be implemented through home aquaculture and community aquaculture utilizing a variety of techniques. Creating a mandatory product involves the stages of development and design. At this stage, all product components, production costs, design, and assembly time are taken into account. Through sustainable product design and evaluation, it is possible to address the assembly performance and difficulties in the assembly process, as well as assembly time and costs. The design and development of this product use the Design for Manufacturing and Assembly (DFMA) method. DFMA is a method used to determine the product design with the best time and cost. In general, this method can also be used in development to improve the quality and measure the improvement of urban aquaculture product designs. It is hoped that urban aquaculture will provide an alternative product design to achieve high-quality products and low production costs.
