Published: January 2024

Offshore facilities are exploration areas that can be removed on the beach from a geographical location. Offshore facilities are located offshore and far from land with different forms of construction and very limited space for workers, so that occupational safety and health factors are a top priority in implementing For this reason, it is necessary to pay attention to the proper scheduling and equitable replacement of crew so that activities carried out at Offshore Facilities can reduce the impact of offshore worker accidents. The Critical Path Method (CPM) identifies the critical path as a series of components for the total number of activities and indicates the longest time period with the fastest project completion. The critical path starts from the first activity to the last project. The critical path is important for implementation projects. Activities that are delayed on one track will cause a delay in the project as a whole. The estimated time used in CPM is only one that represents normal time (Kholil, et al, 2018). In carrying out a management project to get the critical path, use a parallel layout which is arranged proportionally by calculating the distance traveled. If the company is able to apply the Critical Path Method (CPM) method well, then the project can be completed in the right timeframe and can help the company in planning and controlling projects with more efficient time and costs. PERT (Program Evaluation and Technology Review) is a project management technique that uses three time estimates for each activity. The three estimation numbers, namely a (optimistic timeframe), b (pessimistic timeframe), and m (most likely timeframe). By carrying out the Rescheduling Process using the CPM and PERT Approaches, it can provide information and applications to complete the ongoing project schedule and which will be carried out at a later date besides indirectly contributing to cutting costs incurred in completing the project.

However, recently in several palm oil mills (POM), the Soxhlet method has been replaced by the Near Infrared Spectroscopy (NIRS) method which is equipped with free and open-source software (FOSS). Therefore, the purpose of this study was to examine the application of NIRS in measuring oil loss in EFB and to test its accuracy compared to the Soxhlet method. The data is from primary source of POM during April-June 2022 period (peak harvest times). Normality test and paired T test is used to analyze data. This research also cites case studies of CPO processing companies in Indonesia in the last 10 years (2013-2022) with a focus on oil loss in EFB. The results showed that the oil loss in EFB using NIRS and Soxhlet were 0.50% and 0.49%, respectively. These two values are below the company's oil loss standard (0.62%). Both data are normally distributed and based on the paired T test, it was found that there were no significant differences in the results of oil loss analysis using the NIRS and Soxhlet methods. Compared with data for the last 10 years, they are also below the standard limit of other companies which reaches 3%. Therefore, NIRS is more recommended in terms of time efficiency, safe and does not damage the material.

IMPROVING PERFORMANCE OF THE BANANA AGROINDUSTRY SUPPLY CHAIN USING MCDM (MULTI CRITERIA DECISION MAKING)
Authors: Andanu Odi , Sundari Utari Yolla , Setyowati Erni Dwi Puji
Published: January 2024

The problems faced by the banana agro-industry include the procurement process of raw materials from banana suppliers, which has not been able to meet the industry's needs. The selection process of banana suppliers has not been a factor considered by the industry in its strategic planning. The technology used should be able to produce quality processed banana products, but in reality, production is still below the available normal capacity. The distribution of processed banana products to consumers has not been well identified, and market access is still limited, resulting in stagnant industry development. The aim of this research is to identify the problems related to the performance of the banana agro-industry supply chain, measure the performance of the banana agro-industry supply chain, and provide and evaluate solutions that can be used to improve the performance of the banana agro-industry supply chain. The method used in this research is to measure the performance of the supply chain using weighting with the multiple criteria decision-making (MCDM) method, which consists of the Analytical Hierarchy Process (AHP), determining alternative solutions using the VIKOR (Vise Kriterijumska Optimizacija I Kompromisno Resenje) method. The results show that the identification of problems in the banana agro-industry supply chain consists of 5 main criteria and 20 sub-criteria, as well as 7 proposed solutions. The measurement of the supply chain performance resulted in a score of 32.032 (poor), indicating that the performance of the banana agro-industry supply chain is still low. The alternative solution provided to improve the performance of the banana agro-industry supply chain is to establish collaboration and partnerships among supply chain stakeholders.
Do Autistic Traits, Handedness, Sex, and Age Predict Hemispheric Bias During Facial Emotion Processing?

Right-hemisphere brain regions are strongly implicated in facial emotion processing (FEP), a phenomenon termed right-hemispheric bias (RHB). Variability in FEP hemispheric bias is thought to underpin differences in facial emotion recognition ability. Differences in FEP hemispheric bias have been associated with autistic traits. However, research to date investigating factors affecting FEP hemispheric bias is inconsistent. 427 adults recruited from the general population aged 18-67 years completed the Autism-spectrum Quotient (AQ). We also assessed covariates previously linked with FEP hemispheric bias including age, handedness, and biological sex. FEP hemispheric bias was indexed using laterality quotients (LQs) calculated from a Chimeric Faces Task, where participants indicated which of two identical (but mirrored) half-emotional half-neutral (no emotion) chimeric faces were more emotive. Linear regression models revealed that AQ total score did not significantly predict FEP hemispheric bias. RHB was stronger in right- compared to left-handed participants. These findings indicate that the relationship between autistic traits and FEP hemispheric bias is nuanced. Additionally, handedness influences hemispheric bias effects during FEP. Future research should endeavour to investigate if FEP hemispheric bias is dependent on the emotion being observed and consider use of more direct measures of hemispheric bias.
Collective victimhood and conflict-related attitudes: A meta-analysis
Authors: Kljajic Marko , Shelef Nadav , vanderWilden Ethan
Published: January 2024

This study presents a meta-analysis of collective victimhood's impact on conflict-related attitudes. Examining 745 estimates from 103 articles, we assess the impact of collective victimhood on hawkishness, reconciliation (attitudes towards current or former adversaries), out-group exclusion (attitudes towards groups with which one is not in direct conflict), and in-group attachment. We find that collective victimhood is associated with greater conflict-enhancing attitudes, though "inclusive" victimhood generally has opposing effects. These results are consistent across a wide range of geographic contexts, types of victimhood experiences, and identities. They also extend to the impact of collective victimhood on the emotions and cognitive perspectives that are often identified as mediators. Methodologically, observational and experimental studies reach similar conclusions about the direction of collective victimhood's impact, but experimental studies find consistently smaller effect sizes.
Near-source effects on DAS recording: implications for tap tests
Authors: Kennett Brian , Lai Voon , Miller Meghan , Bowden Daniel , Fichtner Andreas
Published: January 2024

In the immediate vicinity of a source there are strong gradients in the seismic wavefield that are tamed and modified in DAS recording due to combined effects of gauge-length averaging and local stacking on the local strain field. Close to a source broadside propagation effects are significant and produce a characteristic impact on the local DAS channels. In the presence of topography, of surface or cable, additional effects are introduced that modify the expected signal. All these influences mean that the results of tap tests used to calibrate the channel positions along a DAS cable may give a distorted view of the actual geometry. Such effects can be important for detailed mapping of faulting processes and comparable features.
Chance as a (non)explanation: a cross-cultural examination of folk understanding of chance and coincidence
Authors: Hong Ze
Published: January 2024

Causal explanations are a key component of human cognition. While we possess certain causal models of the world that offer satisfactory explanations for a range of phenomena, our cognitive capacities have their limits when dealing with the complexities of the world, leaving the causes of many events elusive. In this paper, I integrate ethnographic and historical evidence to show that, despite our limited understanding of why certain events occur, people throughout human history and across diverse societies have seldom invoked “chance” – a concept that has gained significant importance in contemporary, modern societies – as an explanation. Instead, they frequently propose putative causal relationships or posit intermediary entities such as “luck” to account for why specific events unfold within their particular spatial-temporal contexts. I discuss the psychological, cognitive and cultural evolutionary factors that hinders the development of chance-based explanations, and argue that the conceptualization of chance as something measurable and its subsequent acceptance as a legitimate explanation emerged relatively late in human history, marking a pivotal intellectual shift with profound implications on how we perceive and manage uncertainty in our daily lives.
