Appropriate environmental performance is considered one of the most important indicators in the sustainable development of organizations and industries. Evaluating the environmental performance in ports as one of the two main parts of the maritime transport system is of particular importance. Therefore, the current study was designed and conducted to develop a method for evaluating the environmental performance of ports based on the fuzzy analytic hierarchy process (FAHP). In the present study, 22 experts in the field of environment and marine sciences were selected in 2020. Firstly, various studies on the factors affecting the environmental performance of ports were reviewed. Secondly, a questionnaire was designed to assess ports’ environmental performance. Thirdly, this questionnaire was developed using the Delphi technique. Finally, by determining the weight of each parameter, the method of environmental performance assessment in ports was developed based on the FAHP. The final normalized weights for six environmental performance factors including reactive and proactive performance, sustainability, socio-cultural, economic, and governance were estimated 0.202, 0.241, 0.226, 0.070, 0.080, and 0.182. Additionally, it was found that each of the parameters had a different weight and impact on these factors. The highest and lowest impact on the environmental performance index belonged to environmental risk assessment (weight=0.217), cultural effects, and justice (weight=0.107). In the current study, a new method was developed for evaluating the environmental performance of ports based on six factors, 32 parameters, and FAHP. Therefore, this method may provide an effective step in reducing environmental impacts and improving the level of environmental performance in ports to achieve the goal of green port.

Menentukan sumber pembelajaran pendukung yang efektif dalam E-Learning merupakan suatu permasalahan yang kompleks, karena keputusan yang diberikan untuk berbagai kriteria yang ditujukan untuk memberi prioritas kepada alternatif yang digunakan. Pendekatan Fuzzy-Analytic Hierarchy Process (Fuzzy AHP) termasuk salah satu prosedur yang bisa menjadi solusi dari permasalahan ini. Metode ini dapat digunakan untuk menentukan keputusan dalam penaksiran kepada kriteria yang sudah ada sebelumnya. Dari perhitungan pengujian yang dilakukan, YouTube mendapat peringkat tertinggi yang lalu dibawahnya diikuti oleh Google, Brainly, dan yang terakhir Slide Player. Dari perhitungan tersebut, dapat disimpulkan bahwa YouTube bisa dijadikan sebagai sumber pembelajaran pendukung dalam sistem pembelajaran E-Learning.

Today, it is very significant to select appropriate welders in shipbuilding industry. The fact that there is a really tough competition between shipyards triggers the increasing of welder quality. Higher welder quality means higher quality welding workmanship. If a shipyard has a high quality workmanship, it has bigger competitive power than its rivals. Therefore, shipyard management must take welder selection into more consideration. In this study, the weights of welder selection parameters of shipyards were determined by utilizing Chang’s extent analysis method. In this way, it is aimed to understand the point of view of shipyards in selecting welder. In addition, taking into account the important parameters in welder selection, the welders can improve their weak sides. Consequently, the results obtained from this study are believed to be a guide for the people who want to work as a welder in shipyards.
