Managing the spread of COVID-19 pandemic in Indonesian sea transportation

COVID-19 has been pandemic since the early 2020 and many efforts have been carried out worldwide. Among others, managing the spread of pandemic has been focused on air transportation since the mobility of people has been more actively using aeroplane hence the possibility of infecting people is much higher. Despite less intense, efforts to minimise the blow-out of COVID-19 in sea transportation have also been conducted. The International Maritime Organization (IMO) released guidance such pretravel information to crews and customers The types of guidance include the following items, namely pre-departure, social distancing, the use of masks, personal hygiene, environmental hygiene, and training. In the case of Indonesia, similar direction is introduced and implemented to cargo and passenger vessels. The current paper discusses the Indonesian regulation of managing COVID-19, which is based on IMO/WHO guidance, together with its implementation in the daily activities of people in sea transportation. A survey questionnaire is made out to collect the relevant information. The discussion covers the implementation of such guidance to Indonesian cargo and passenger vessels difficulties in applying the regulation on those ships and the related solutions.This work is part of a project that has received funding from the British Council under the Newton Institutional Links Grants -Ensuring the safety of Indonesian seafarers and fishers in the time of COVID-19 and beyond (agreement No. 623457938), in conjunction with the Indonesian Governmental Funding from the Ministry of Education, Culture, and Higher Education (agreement No. 1369/PKS/ITS/2022

Thermal Evolution of the Proton Irradiated Structure in Tungsten–5 wt% Tantalum

We have monitored the thermal evolution of the proton irradiated structure of W–5 wt% Ta alloy by in-situ annealing in a transmission electron microscope at fusion reactor temperatures of 500–1300 °C. The interstitial-type a/2 dislocation loops emit self-interstitial atoms and glide to the free sample surface during the early stages of annealing. The resultant vacancy excess in the matrix originates vacancy-type a/2 dislocation loops that grow by loop and vacancy absorption in the temperature range of 600–900 °C. Voids form at 1000 °C, by either vacancy absorption or loop collapse, and grow progressively up to 1300 °C. Tantalum delays void formation by a vacancy-solute trapping mechanism

Diving into the vertical dimension of elasmobranch movement ecology

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements

Efforts to Improve K3 Culture (Occupational Safety and Health) in Harmonika Door Welding Workshop Smes

Counseling and socialization of the use of Personal Protective Equipment (PPE) is one of the efforts to support Occupational Health and Safety. Welding workshop "Jaya Mandiri" is an activity partner that requires this. The purpose of the activity is to increase awareness and skills on the importance of using PPE when working. For this reason, making SOPs for the use of PPE is a mandatory procedure to start a job. The method used is counseling and demonstration of the use of PPE then followed by the use of PPE while working. The results of the activities were analyzed using a Likert scale. After that, the SOP and supervision methods were determined by the workshop owner in the use of PPE so that it became a habit to become a culture. The results obtained after counseling and demonstration of PPE are an increase in understanding and skills in the use of PPE from employees. From the results of the Likert scale analysis, the highest was the use of welding safety helmets after counseling 74.29% from the previous average of 31.43%. The lowest result is the use of apron (Apron) 57.14% before 22.86%. It was also found that one of the employees who had the highest understanding and skills in the use of all PPE, namely Munahar, reached 84% after counseling from only 40% previously. The skills and discipline of employees in the use of PPE still need to be improved by means of supervision by SME owners. The service implementation team together with the workshop owners and employees agreed to make an SOP in supervising the use of PPE to support K3 so that it becomes a good and entrenched habit
