Abstract

Purpose: This study aims to investigate the current state and challenges of remanufacturing practices in Indonesia, particularly in the heavy equipment sector, including key barriers and opportunities identification. Methodology: A survey involving 23 companies working in the heavy equipment sector was conducted to gather their remanufacturing practices, challenges, and perspectives. The study examines issues related to definitions, regulations, core availability, and quality assurance of remanufactured items. Results: The survey reveals wide variety and inconsistencies in defining remanufacturing due to the absence of standardized definitions and government regulations. This triggers complexities in business process especially in sourcing high-quality cores and communicating the quality of remanufactured items to consumer. Applications/Originality/Value: The findings highlight the need for future research to create a conducive ecosystem for remanufacturing in Indonesia including regulation and policy development. This study provides valuable insights for enhancing the development of the remanufacturing industry.

Abstract

Dalam aktivitas produksinya, UPT Logam Yogyakarta menghasilkan limbah dari proses pengecoran alumunium berupa terak yang dapat menimbulkan dampak negatif kepada lingkungan dan masyarakat. Oleh karena itu, tujuan penelitian ini adalah untuk mengevaluasi dampak lingkungan yang ditimbulkan dari proses produksi alumunium di UPT Logam Yogyakarta menggunakan metode Life Cycle Assessment (LCA). LCA merupakan salah satu metode penilaian dampak lingkungan yang terdiri dari empat langkah, yaitu penentuan tujuan dan ruang lingkup, life cycle inventory (LCI), life cycle impact assessment (LCIA), dan interpretasi. Produk downlight lampu dipilih sebagai objek penelitian agar dapat memberikan pemahaman yang mendalam tentang implementasi LCA pada proses pengecoran aluminium. Hasil LCA menunjukkan bahwa penggunaan batang aluminium memberikan dampak terbesar pada semua kategori dengan nilai kategori GWP sebesar 355 kg CO2-eq., kategori AP sebesar 1,32 kg SO2-eq. kategori AP sebesar 0,087 kg Phosphate, kategori ODP sebesar 5,36E-13 kg R11, kategori ADP elements sebesar 1,11E-4 kg Sb, kategori ADP fossils sebesar 3,87E+003 MJ, dan kategori HTP sebesar 1,32E+003 kg DCB. Strategi pengurangan dampak lingkungan dapat dilakukan beberapa cara, yaitu dengan menerapkan produksi bersih dan melakukan pengolahan limbah dengan cara yang benar

Abstract

The ever-increasing volume of municipal waste in Yogyakarta brings overload capacity problems to the Piyungan Landfill. This circumstance results in environmental pollution which harms the local residents. Therefore, this study was conducted to determine the impact of pollution in the Piyungan Landfill from an economic, environmental, and social perspective. Furthermore, this study aims to formulate a waste management strategy in the landfill using the fishbone analysis to find out the root causes of existing problems, the stakeholder analysis method to determine the role of each stakeholder involved, and the SWOT analysis method to determine potential strategies for waste management. From those analysis methods, it is concluded that there are six root causes in the landfill, namely the waste management process, the amount of waste, landfill facilities, the technology used, the implementation process, and government policies. This study recommends several waste management improvements from the combination of strengths and opportunities factors (SO Strategy). The combination of these strategies includes: (1) establishing cooperation policies with foreign parties. (S1, O1); (2) optimizing budget and waste management technology. (S2, O2); (3) providing transportation facilities and technology to optimize the recycled waste business. (S3, O2, O3); and (4) maximizing resources to optimize the recycled waste business. (S4, O3). These strategies are expected to be able to increase the capacity and capability of the Piyungan Landfill in managing waste and overcoming environmental pollution.
