“…Based on the interview with several owners of traditional shipbuilding companies, it is known that the COVID-19 pandemics have disrupted shipbuilding activities, resulting in a decline in ship production. Using the seven waste principal for manufacturing such as Transport, inventory, motion, waiting, over-processing, overproduction and defects (Putri and Dona, 2019; Praharsi et al , 2019a, 2019b), non-value-added activities that interfere the shipbuilding process are identified in Table 8. The three shipyard owners identified four wastes categories, namely, inventory, waiting, over-processing and defects.…”

Purpose This study aims to apply a Lean Six Sigma framework to support continuous improvement in the maritime industry (shipbuilding, logistics services and shipping companies) during COVID-19 pandemics. By applying the concepts of Lean Six Sigma and supply chain resilience, the most suitable continuous improvement method for the maritime industry is developed to maintain a resilient supply chain during COVID-19. Design/methodology/approach A specific shipbuilding, logistics services and shipping company in Indonesia is chosen as the research object. The Lean Six Sigma framework reveals the wastes through the supply chain resilience concept, and implements internal business processes to maintain optimal system performance. Findings The paper identifies important implementation aspects in applying Lean Six Sigma to shipbuilding, logistics services and shipping. The DMAIC (define, measure, analyze, improve and control) approach is applied to achieve supply chain resilience. Resilient measures are generated for the case companies to maximize performance during the pandemics. Practical implications This paper provides a new insight for integrating Lean Six Sigma and resilience strategies in the maritime industry during COVID-19 disruptions. The authors provide some insights to sustain the performance of the maritime industries under study. Originality/value This study is part of the first research in the maritime industry that focuses on continuous improvement during COVID-19 using Lean Six Sigma and supply chain resilience.

“…Traditional boat design can be improved in order to improve safety and performance, and it is still accepted by a local fisherman after the improvement. The improvement of the traditional fishing boat construction was proposed with model validation [1]. The fishing boat was designed based on local wisdom in Southeast Sulawesi Fishermen [2].…”

Indonesia Government through the Ministry of Maritime Affairs and Fisheries is holding a fishery boat procurement assistance program of gross tonnage (GT) 5 to 30. In order to be effective investment for the program, a comprehensive study on fishing boat is emphasized to be carried out. This study aims to determine the investment components of a fishing boat with GT of 12, 21 and 30 based on the consideration of the local content, determine the feasibility of fishing boats investment including the local content aspect, and determine the weight of local content for the investment of fishing boat. The investment feasibilty was analysed by using Net Present Value (NPV) and Internal Rate of Return (IRR). In the present results, the three fishing boat sizes of GT 12, 21, and 30 were economic feasibility and suitable in order to support the welfare of fishermen in Sinjai Regency, South Sulawesi Province. The NPV and IRR within 10 years for the fishing boat size of GT 12 are approximately 823 million rupiahs and 77% respectively, 988 million rupiahs and IRR of 54% for GT 21, and 979 million rupiahs and 38% for GT 29. The weight of the local content aspect contributes in average of 81.47% on the investment of the fishing boat wherein the local content includes boat hull buliding, fishing equipment, and labor cost. In addition, the weight of the local content aspect for ship operation is average of 61.88% wherein the local content includes fishermen salary and fishing aggregating device.

“…Within this context, wood, which can be considered the most ancient material used for boatbuilding, presents the following advantages: it requires low amounts of energy for growth and production as compared to FRP and steel and it is a renewable resource and has a net carbon negative footprint [14]. It is currently reacquiring its appeal, and several studies focused on wooden boats have been recently proposed [6,17,18].…”

The aim of the present investigation was to assess the behaviour of strip-planked parts by comparing wooden specimens glued using two different bio-based adhesives with wooden specimens glued using a conventional epoxy resin generally used in boatbuilding. Experimental tests in accordance with UNI EN standards were performed in order to evaluate mechanical properties such as tensile strength, shear strength, elastic modulus and shear modulus. In addition, compression shear tests were performed in order to assess the shear modulus of the adhesives. The obtained results demonstrate that the mechanical properties of the investigated bio-based adhesives are comparable to, and sometimes better than, the conventional epoxy resin. Moreover, the experimental results give useful information for the design of wooden boats when the strip-planking process is used. Furthermore, a new procedure to assess the shear modulus of elasticity and shear strength, using the application of compression loadings, was proposed. The results were compared to standard lap-joint tests and showed even lower dispersion. Consequently, the testing procedure proposed by the authors is valid to assess shear properties under compression loading, and it can be applied in most laboratories since it involves the use of common testing devices.
