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

Pertumbuhan penduduk yang semakin meningkat menyebabkan peningkatan produksi sampah secara signifikan. Kesadaran masyarakat untuk sekadar memilah dan memisahkan sampah pun masih rendah. Sosialisasi pemilahan sampah dan pembentukan usaha bank sampah sebenarnya sudah makin marak. Namun, karena kurangnya promosi bank sampah atau kurang baiknya sistem manajemen bank sampah menyebabkan bank sampah saat ini sepi peminat. Hal ini dialami oleh bank sampah mitra, yaitu Bank Sampah Guyub Rukun. Kesadaran masyarakat di sekitar Bank Sampah Guyub Rukun untuk menabung sampah pun masih rendah. Selain itu pengurus juga masih belum mampu mengelola bank sampah secara profesional. Oleh karena itu, solusi yang ditawarkan: (1) melakukan pelatihan mengenai pengelolaan keuangan, (2) melakukan pelatihan pembuatan paving blok dari sampah plastik, dan (3) melakukan sosialisasi Bank Sampah Guyub Rukun kepada masyarakat yang lebih luas.
