New Normal becomes the way out to keep Indonesia's weakened economy because of covid-19 pandemic stays in balance. Of course, New Normal must be well-balanced with the application of strict protocols to reduce transmission rates and anticipate a surge in new cases. From a few points of pandemic protocols, using face mask is considered as the most-effective basic need. Re-designing the mask is aiming at eliminating the worsening feature and developing the improving feature. This research is developing the widely used 1-ply mask, which doesn't meet WHO standard regarding cloth-material mask that must be made in 3-ply. The method used in this research is TRIZ (Teoriya Resheniya Izobreatatelskikh Zadatch), an inventive problem solving theory to the issues regarding ideas, products, or concepts, in this case is face mask redesigning concept. In this research, the data are collected by doing library research to obtain secondary data that will be processed in qualitative and quantitative methods. The results shows the aspects that should be eliminated from cloth-material face mask are brittle for being easily damaged, short period of usage, and non-reusable. After the redesigning concept is carried out using the principles and features of TRIZ method, some aspects such as weight, material, design, and functionality are developed. The result is a relatively light weight face mask because the using of PLA+ filament-based material with good durability and environmentally friendly. This design has longer period of usage, and user only needs to replace the additional inserted tissue every 4 hours. The researchers hope that the new design can be further developed by government to deal with New Normal and other possibilities in the future.

This article explains the execution and delivery progression phases of the project lifecycle. It is the third phase of the project lifecycle that leads to the final realization of the project's goals. However, this essay will describe the understanding of the ‘enlightened planning’ approach during the execution and delivery strategy progress of a project’s lifecycle. The features and details in the Enlightened Planning and PMI PMBOK Guide are compared. The author explored the nature and role of basic frameworks such as the project lifecycle, the process phase structure, and key project definition questions — the seven Ws (Who, Why, What, Which way, Wherewithal, When, Where). Combining Enlightened Planning and PMI PMBOK Guide, the differences between the two approaches are given. In addition, the author elaborated the advantages and disadvantages of the two approaches in current practice.

A buttress on the need for welfare program in Nigeria and the important obligation to consider the Economics’ and CIA’s contextual position for the dependency ratios, both total and elderly dependency ratio alongside the consideration of the age structure and demography statistics of Nigeria relatively to other economies, particularly as an elixir for the declining older population in Nigeria and the aged male contraction in the nation. Although, older female population is higher in every country as obtainable globally, the Nigerian case is that of drastic contraction in both aged male and older population generally. Therefore, the submission is that the government has to consider total dependency ratio to the elderly dependency ratio, which is all-encompassing in order to cater for the declining older population and to appropriate the requisite welfare cum benefits programs in the nation.

Bullying is rampant and has severe effects on the health and wellbeing of the employees. Additionally, it also undermines job satisfaction and performance, thus affecting productivity. Bullying among seafarers is widespread, and their isolation from the rest of the people while at sea can enhance aggressive behaviour. Bullying is widespread among seafarers and severely affects them in core areas of their life. There is a significant effect of bullying on mental health. However, the Omani seafarers are loyal to their jobs and claim to be happy at sea despite the challenges and hardships. While there are different forms of bullying in the workplace, verbal abuse is the most rampant. The study seeks to highlight the impact of bullying on seafarers' happiness and job satisfaction who work in a shipping company. A questionnaire with nine questions was prepared based on the authors' experience and sent by mobile phone to fifty officers and crew members working onboard. More insight into workplace bullying among seafarers is essential in formulating adequate law, thus improving seafarers' health and safety.

In Container terminals, a quay crane's resource hour is affected by various complex nonlinear factors, and it is not easy to make a forecast quickly and accurately. Most ports adopt the empirical estimation method at present, and most of the studies assumed that accurate quay crane’s resource hour could be obtained in advance. Through the ensemble learning (EL) method, the influence factors and correlation of quay crane’s resources hour were analyzed based on a large amount of historical data. A multi-factor ensemble learning estimation model based quay crane’s resource hour was established. Through a numerical example, it is finally found that Adaboost algorithm has the best effect of prediction, with an error of 1.5%. Through the example analysis, it comes to a conclusion: the error is 131.86% estimated by the experience method. It will lead that subsequent shipping cannot be serviced as scheduled, increasing the equipment wait time and preparation time, and generating additional cost and energy consumption. In contrast, the error based Adaboost learning estimation method is 12.72%. So Adaboost has better performance.

This study aimed to determine the waste that occurs in activities from receiving to delivering of finished products that can result in delays in the delivery of audio to Japan. The waste identified is limited to activities in the finished goods warehouse. The problem that occurs is the delay in product delivery, because the product is not ready to be delivered so that it causes delays. The lean approach is used to reduce waste in the overall work process activities in the finished goods warehouse. Waste identification was performed through the 7 waste approach. Process Activity Mapping is one of the tools of VALSAT, and is looking for critical waste to find the root cause of waste. Delay can be minimized by making improvements to the layout of the warehouse and routine inspection of goods transporters. Companies should use lean to reduce the waste that occurs so there is no delay in the delivery of audio products.
