While it is understandable that lean and green practices are mostly sensible for large companies, it is also important to bring these practices to small and medium enterprises (SMEs), as they are the dominant players in various industry sectors. SMEs are part of larger supply chains and contribute substantially to the economy, and thus perhaps there is a need for a workable model that attracts them to the lean and green practices. This study aims to find gaps in the lean-green research area that require development in future studies, especially for SMEs. This study uses an analysis of systematic literature reviews (SLR) and involves carefully selected articles from different databases or sources. This SLR was conducted in an effective and structured way using keywords entered into the search engine and found as many as 157 peer-reviewed journal articles, which were studied further using quantitative and qualitative approaches. The bibliometric analysis carried out made it possible to observe research trends on lean and green from 1996 to 2022. To find different research dimensions on lean and green topics, an in-depth evaluation was carried out on the linkage between lean, green, supply chain management, sustainability, and other management approaches. This study finds a lack of empirical research studies that comprehensively focus on investigating the impact of lean and green practices on the supply chain sustainability performance of manufacturing SMEs and involve all three aspects of the triple bottom line (3BL). Our review suggests such a robust and workable model for SMEs is not currently available. A limitation of our review is the use of keywords or “terms” to select articles, as well as the subjectivity of the researcher. Finally, we identify the research streams, criteria, findings, limitations, and enablers or challenges of 17 selected published journal papers on lean-green studies in SMEs and propose a number of research questions for future research directions.

One of the major challenges in aquaculture is fish feeding management. Inappropriate feeding practices could threat the fish’s growth and health, may lead to negative environment impact due to excess food contamination, and more importantly high operations cost. This study is aiming at proposing a fish feeding management system for OceanFarmITS, an offshore aquaculture unit designed by Marine Research Centre of Institut Teknologi Sepuluh Nopember Surabaya. One of the most commercially popular fish, Tiger grouper is selected to be cultivated in OceanFarmITS pilot project. The fish feeding management systems include fish feeding arrangement and fish feeder system that is customized specifically to OceanFarmITS operations nature. Automatic fish feeder is an alternative to solve existing feeding problems such us inefficiency of conventional or manual feeding. The proposed system consists of a control system using microcontroller Arduino board to receive data from sensors then send the instruction to the motor driver. Moreover, it has alarm system that sends notification to Aquaculture operator when food storage in silo tank has reached a limit level. The proposed design of feeding system would support operations of OceanFarmITS to conduct feeding activity efficiently by minimizing operations cost and environmental impact while keep fish optimal growth.

New product development is an important innovation that should be done to meet consumers’ new trends. This paper is prominent as it discusses new product development through the inactive problem perspective in SMEs in Indonesia as a way to explore customers’ expectations, which are often challenging to analyze. The capability to develop a new product based on the inactive problem perspective allows SMEs to become pioneers that possess various competitive advantages, including strong brand awareness. This study included 14 samples of SMEs to represent the characteristics of SMEs in Indonesia between 2016 and 2018. We used the particle swarm optimization approach for the decision making of several SME parameters with the profit maximization function. This paper is the first paper to discuss the relationship between the cost of ideas and production costs in the types of SMEs with an inactive problem perspective in Indonesia to obtain maximum profits by considering various factors that affect the costs and revenue of SMEs. This paper also analyzes the cost used for an idea realization to get maximum profit. This study shows that differences were found in each type of SME, and these difference were related to the amount of funds that were used to explore, realize, and make a profit out of a specific idea.

A product redesign strategy can effectively shorten design lead time and reduce the manufacturing cost of innovative development for the manufacturing industry to stay competitive. Identification of function components is the basis of product redesign. Existing practices to identify the critical component and customer requirements are considered while complaint and historical failure data, crucial for improving product reliability, are frequently ignored. The objective of the article is to develop an integrated framework of product redesign and innovation considering customer requirements and product failure modes. The novel framework integrates the design for manufacturing and assembly (DFMA) and design for reliability (DFR) approaches, as well as finite element analysis to address the cost reduction of product redesign at early-stage, reliability improvement, and higher customer satisfaction. The proposed integrated framework is validated using an example of an Indonesian SME’s cooking stove. The redesigned cooking stove showed substantial improvements with 5.46% cost reductions, 20.32% design efficiency, and an 52.81% safety factor.

The main activities in a remanufacturing system includes core acquisitions, remanufacturing operations, and remarketing. Core acquisitions are challenging for remanufacturers because remanufacturing in closed-loop supply chains is characterized by uncertainty in quality, timing and volume. The uncertainty is generally defined as incomplete or incomplete information. Sorting of quality incoming products in the remanufacturing system is a complex problem. On account of all quality conditions can be related either directly or indirectly, making it difficult to define certain conditions individually. Considering that the acquisition process involves many conflicting assessment criteria and subjective-qualitative considerations, an integrated method is needed to prioritize criteria selected. Therefore, this study makes a major contribution to research on multi-criteria sorting problem by developing a new hybrid method. This study focuses on development of a multi-criteria quality sorting model in the remanufacturing system based on a hybrid approach, namely Decision Making Trial Evaluation and Laboratory (DEMATEL) Analytical Network Process (ANP) and Grey Clustering. The DEMATEL approach is proposed to evaluate and to develop the dependency of criteria, and ANP method is utilized for weighting the criteria as well as Grey Clustering is proposed for modelling of uncertainty issues. The model was successful as it was able to identify the most important criteria which proposed. This work has found that maintenance history is the most important attribute in assessing the quality of incoming cores. This finding has important implication for selecting the best maintenance strategy of heavy-duty equipment during the use phase.
