Abstract

ABSTRAK Sebuah lini produksi dirancang untuk memastikan bahwa aktivitas produksi berlangsung lancar dengan output maksimal. Namun, kelancaran lini produksi dapat terganggu jika terjadi bottleneck dalam aktivitas atau proses tertentu, yang dapat menurunkan tingkat produksi secara signifikan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis bottleneck dalam lini produksi industri makanan menggunakan pendekatan simulasi. Hasil simulasi kondisi eksisting menunjukkan bahwa proses packing menjadi bottleneck utama. Melalui skenario perbaikan berupa kombinasi penugasan mesin manual packing yang lebih fleksibel dan penambahan konveyor, simulasi membuktikan bahwa throughput produksi per jam dapat meningkat sebesar 8,6%. ABSTRACT A production line is designed to ensure that production activities run smoothly and achieve maximum output. However, its smooth operation can be disrupted if a bottleneck occurs in certain activities or processes, significantly reducing the production rate. This research aims to identify and analyze bottlenecks within a food industry production line using a simulation-based approach. The simulation results of the existing conditions indicate that the packing process is the primary bottleneck. Through an improvement scenario involving a combination of more flexible manual packing machine assignments and the addition of conveyors, the simulation demonstrated that hourly production throughput could increase by 8.6%.

Abstract

This research is driven by the need of PLN Distribution Main Unit to mitigate the extreme risk of high account balances on the 21st of each month, which can disrupt cash flow and financial performance. One mitigation strategy is replacing conventional kWh meters with Advanced Metering Infrastructure (AMI), or two-way meters, which allow remote disconnection. The purpose of this study is to prioritize customers for meter replacement based on limited material availability and to optimize replacement routes under restricted team resources. The method used involves the K-means algorithm for customer segmentation, validated by silhouette score, which resulted in six optimal clusters. Genetic algorithm was then applied to determine the most efficient routes based on distance and time. The results showed that the optimal route had a minimum total travel distance of 1,434.29 km and a total time of 18,868.58 minutes, using a population size of 50 chromosomes and 500 generations. This study is expected to offer an effective solution for improving operational efficiency and risk mitigation at PLN.

Abstract

The coal mining logistics industry in Indonesia has a strategic role as the world's largest coal producer, with a significant contribution to state revenue. This study aims to analyze the main obstacles, wastes that occur, and proposed improvements in the coal loading and unloading process at PT XYZ to increase efficiency and productivity through a lean thinking approach. The methodology of this research includes a qualitative approach through value stream mapping and quantitative using fishbone diagrams to produce a comprehensive analysis. The analysis is carried out through process activity mapping, the preparation of current state maps, and the design of future state maps to provide suggestions for improvement. Based on the results of the study, several recommendations for improvement were obtained from the results of the analysis on coal unloading or loading activities which included Value Added (VA) or Necessary but Non-Value Added (NNVA). The proposed improvements include the application of double crossing dismantling methods, digitization of administrative processes, and the use of drone technology to facilitate the physical inspection process in the field. If the proposal can be implemented, there will be an increase in the time effectiveness of coal loading and unloading activities by 14.20%, with details of unloading activities increasing by 25.30% or from 1,004 minutes to 750 minutes, and coal loading activities by 3.10% or from 3,067 minutes to 2,972 minutes.

Abstract

Ships are often used to move cargo, and their main engines are crucial. Accidents and financial losses might result from the main engine being in poor condition. Before completing maintenance, conducting a failure analysis is necessary. The existing method is static and involves using a list of failure modes from the engine's manufacturing phase. This study proposes a preliminary design of dynamic system prototype that seeks to improve ship engine monitoring of status. It includes features such as a list of failure modes and codes based on ISO 14224:2016, data collection unit worksheet, and dynamic charts for visualizing the results. Two testing iterations were performed on the prototype. First, literature data obtained from the internet was used to generate annual and monthly report charts, confirming the functionality of the prototype. Second, real data from engine failures on the tanker ship were used to ensure logical correlations among failure causative factors. The result from real data testing included Structural Deficiency (STD), External Leakage Fuel (ELF), and Breakdown (BRD) were shown. Based on these results through the prototype simulation, can be taken into consideration for the ship's crew and shipping company management to plan oil monitoring, heating the oil properly, and conduct routine maintenance check as a preventive action to reduce the impact of engine damage in the future due to Engine Breakdown and Structural Defiency.
