Authors: Hariyanto I H , Pratomo D G , Darminto M R 
Published: February 2021

Abstract
The accelerated development of Palu City and its vicinity areas surrounding Palu Bay has changed the land use especially in the coastal area. These changes may reduce the function of the beach as a natural bathing wave. The 2018 Palu Bay tsunami have varying heights. This height variation is probably because of the difference in both geographical and geological conditions in coastal areas which are located surrounding the bay. The research used the contingency coefficient as a method for determining the magnitude of the correlation between tsunami heights and several parameters, such as: land cover, slope, and lithology. The results show the land cover parameter has the most effect the height of the tsunami wave recorded. Based on the significance test using the Chi-Square, the slope of the coastal area is the most representative parameter with a 66% confidence level.

Abstract
In the shipping industry, especially shipyards which are used for building and repairing ships, a lot of labor is required. Due to a lot of labor, of course, makes the salary component to be a fairly large cost component in the company. Nowadays, many shipyards have turned to outsourcing-based shipyards, to reduce indirect costs. However, other shipyards have not yet become outsourcing-based shipyards, so the number of workers is still relatively large. The high number of permanent workers in a company indicates the effectiveness and efficiency of the workforce in the company is still lacking, so that the company will experience losses because the workload received by each workforce does not match the salary received by the worker. The research was conducted using the Full-Time Equivalent (FTE) method, which the components required for this method are the effective working days in 1 year and the effective working time in 1 year. After the analysis was carried out, the percentage of reduction in labor remained at 55%, and the percentage reduction in indirect costs is 38%.

Published: February 2021

Abstract
Energy sources that can be utilized by humans are oil and natural gas. However, in exploration activities, there are problems regarding the risk level determination of equipment in offshore platforms. The equipment that has an important function for the processing of oil and gas is a pressure vessel. In the contents of the hydrocarbon flow produced by the production well, it consists of various mixtures (gas, crude oil, and water). Therefore, it is necessary to have a separation process between the three fluid phases by using a device, namely a separator (pressure vessel). If the process of separating the three-phase from the hydrocarbon flow fails, it will result in product failure and also threaten the workers and the surrounding environment. So, this study will use the risk-based inspection (RBI) method to determine the level of risk from a pressure vessel. The risk-based inspection (RBI) method was chosen because the oil and gas processing industry have a high level of risk so that safety for business management and environmental conditions is the main consideration. Another advantage of using the risk-based inspection (RBI) method is the reduced shutdown time and the number of equipment inspections.

Published: February 2021

Abstract
In recent years, small-scale LNG has contributed significantly in supplying the demand from industry users of natural gas as clean fuel. Small-scall LNG has the advantages of providing the greater operational flexibility and lower initial investment cost than conventional LNG or pipeline supply. Focusing on the case in Indonesia, many designed gas-fuel power plants are located in remote area or in the limited depth of water level especially in eastern part of Indonesia, such as Lombok and Bali. Therefore, small-scall LNG is purposed to overcome the natural gas demand in such conditions. Two scenarios were developed in this study in utilizing the conventional LNG carriers to deliver the natural gas from origin located in LNG terminal Benoa, Bali, to several power plants in Bali and Lombok. Both scenarios are new ship LNG building and the conversion of Landing Craft Tank (LCT) into non-conventional LNG carrier. Economic analysis on the LNG Distribution to power plants in Bali and Lombok utilizing mini LNG carriers is the main objective of this study. Capital Expenditure (CAPEX) including mini-LNG carrier, investment in jetty, storage facility, regasification unit and the system distribution to the power plant were considered. While the Operational Expenditure (OPEX) consist of operational and maintenance cost in receiving terminal and LCT. The result of this papers can be concluded that based on the economic perspective, utilizing the mini LNG carriers are feasible and requires relatively small cost to supply the LNG demand in Lombok and Bali.
Field investigation on the state of marine safety of traditional fishery
Authors: Nugroho S , Nugraha S A 
Published: February 2021

Abstract
Gaining an understanding of the characteristics that affect maritime safety is not easy. It is necessary to have sufficient information about what can support safety. Problems in traditional fishing are visible from the low level of safety and the availability of information that supports the fishers’ safety. Several accidents that occur due to negligence of work prove that the low quality of information is also the cause of failure to maintain safety. What commonly happens is that there are differences and discrepancies in recorded accident data with reality on the field, where this is rarely known even though accidents occur. It shows that there is no data integrity to support safety. When talking about safety, there must be a potential failure, which can be identified from the information obtained. However, in reality, the information used to support fishers’ safety is not available, so traditional fishing boats’ safety cannot run optimally due to data unavailability. When safety governance cannot be carried out using correct data, safety management becomes ineffective. By investigating the state of marine safety and examining the role of information on traditional fishers’ safety, it is hoped that it can produce a better mechanism for traditional fishers’ safety.

Published: February 2021

Abstract
Stowage planning is a tedious job. It involves technical and administrative tasks. Evolving data along the process and information completeness should be considered, when dealing with the updating of stowage plans. Recent IMO Regulations have brought forward a set of advanced stability criteria, far beyond the computation of metacentric height. The paper outlines the challenges on the implementation of proper stowage planning practices from the perspectives of safety and operational efficiency.
User Aspiration and Design of Functional Architecture in Seafarer’s Certification Management
Authors: Nugroho S , Putro A T 
Published: February 2021

Abstract
Maritime (kepelautan) is matters related to manning, education, certification, authority, rights and seafarer’s obligations. In marine transportation activities, there are several main instruments that must be in place, namely transportation facilities (ships), transportation facilities providers (shipping companies / government), ship operator service providers (seafarer), certified seafarers / producers of seafarers (training institutions) and infrastructure, such as ports, channels, warehouses, and so on. The relationship between seafarers and seafarer certification (education and training institutions / government) and shipping companies is a concern in this study, especially in relation to the impact of many falsification of seafarer certificates, despite the implementation of an online database certification system that is centralized in Directorate General of Sea Transportation (DJPL). There are 3 (three) major problems that are still popular at this time, for instance unoriginal of seafarer certificates, unpaid seafarers or late receiving wages for more than 1 (one) wage period, and seafarers have a difficult time to find jobs on board. One of the available instruments to solve this problem is the intelligent transport system (ITS) architecture which is liable to be adopted in mapping the aspirations of marine transportation stakeholders, blockchain technology, such as decentralizing (one of the pillars / characteristics of blockchain technology) seafarer certificate database. A cost benefit analysis will be used in this study to obtain how much does it cost to improve the system and to see the benefit of the product.
Study the variation of surface topography & corrosion resistance of Cr-GO nanocomposite coatings by addition of GO nanoparticles
Authors: Mahmoudi Delaram , Taghizadeh Tabrizi Arvin , Aghajani Hossein 
Published: February 2021

Abstract
The chromium-graphene oxide nanocomposite coating was synthesized successfully by the electroplating method in this investigation. The influence of the addition of GO on surface topography, microhardness and the corrosion behavior of chromium coatings was studied by polarization and electrochemical impedance microscopy methods. The maximum surface microhardness value was measured at a sample with 10 wt% of GO particle equals to 766 HV. The results of surface analysis (Atomic Force Microscopy and microhardness) reveals that the combination of two main factors of GO particle addition and coating thickness has more effect on the surface microhardness than the grain size of topographies. Corrosion results show the addition of the GO particles reduces the corrosion resistance of chromium coating but layer with 5 wt% of GO particles has better corrosion resistance than other composite coatings. Also, results show that corrosion resistance has a meaningful relationship with Sa/Sp ratio.
‘I Kinda Like to Go Off the Track’: Finding David Lynch in the Middle World of Dune
Authors: Amadio David 
Published: February 2021

Abstract
For many scholars of David Lynch’s work, Dune is considered a spectacular failure, a costly creative misstep on the way to Blue Velvet. While it may not be regarded as one of his signature films, Dune contains enough of Lynch’s creative personality to warrant a critical re-examination. The purpose of this study is to place Dune within the context of his earlier work, namely Eraserhead and The Elephant Man, and to mine it for those tropes with which Lynch has become synonymous: enabling the grotesque, interiority and the unconscious mind, and the relationship between industry and flesh. By the director’s own admission, Dune forced him into an aesthetic middle world, wedging him between the midnight movie and mainstream cinema. Using Thomas Leitch’s theory of adaptation in both an archival and teleological reading of Dune, I demonstrate how Lynch asserts himself in this middle world, how he succeeds in honouring the source material while also meeting his authorial desire to reinvent it, to decouple from the archive and ‘go off the track’.
Blood Pressure Trajectories Across the Life Course
Authors: Allen Norrina B , Khan Sadiya S 
Published: February 2021

Abstract
High blood pressure (BP) is a strong modifiable risk factor for cardiovascular disease (CVD). Longitudinal BP patterns themselves may reflect the burden of risk and vascular damage due to prolonged cumulative exposure to high BP levels. Current studies have begun to characterize BP patterns as a trajectory over an individual’s lifetime. These BP trajectories take into account the absolute BP levels as well as the slope of BP changes throughout the lifetime thus incorporating longitudinal BP patterns into a single metric. Methodologic issues that need to be considered when examining BP trajectories include individual-level vs. population-level group-based modeling, use of distinct but complementary BP metrics (systolic, diastolic, mean arterial, mid, and pulse pressure), and potential for measurement errors related to varied settings, devices, and number of readings utilized. There appear to be very specific developmental periods during which divergent BP trajectories may emerge, specifically adolescence, the pregnancy period, and older adulthood. Lifetime BP trajectories are impacted by both individual-level and community-level factors and have been associated with incident hypertension, multimorbidity (CVD, renal disease, cognitive impairment), and overall life expectancy. Key unanswered questions remain around the additive predictive value of BP trajectories, intergenerational contributions to BP patterns (in utero BP exposure), and potential genetic drivers of BP patterns. The next phase in understanding BP trajectories needs to focus on how best to incorporate this knowledge into clinical care to reduce the burden of hypertensive-related outcomes and improve health equity.
Comparison of Fat Repositioning Versus Onlay Segmental Fat Grafting in Lower Blepharoplasty
Authors: Hedén Per , Fischer Sebastian 
Published: February 2021

Abstract

Background
Lower blepharoplasty is one of the most challenging procedures in aesthetic surgery. In particular, blending the lid-cheek junction and correction of the tear trough are prone to failure and unsatisfactory outcomes.

Objectives
The aim of this study was to combine lower eyelid blepharoplasty with a novel technique of autologous fat grafting, commonly called segmental fat grafting, and to analyze the safety and efficacy of this approach.

Methods
A retrospective analysis of 339 lower blepharoplasties was performed to compare the novel technique of segmental fat grafting to traditional fat transposition during lower blepharoplasty. Outcomes were assessed objectively by several measurements as well as via online survey of 148 invited experts in plastic surgery. Statistical analysis included t test for unpaired and paired samples as well as 1-way analysis of variance for matched data.

Results
There were no differences in baseline characteristics and comorbidities between study groups. After a mean follow-up of 12.9 months (range, 5-120 months), the group that underwent segmental fat grafting had a significant reduction in tear trough width compared compared with the group receiving lower blepharoplasty with fat transposition. Based on an expert (blinded) online survey, segmental fat grafting was superior or equal in 47% and 35% of cases, respectively. Complications (4%) and revision surgeries (9%) did not differ significantly between study groups.

Conclusions
The novel technique of transplantation of a segmental fat graft during lower blepharoplasty is a safe and effective way to overcome tear trough deformity and blend the lid-cheek junction.

Published: February 2021

Abstract
Reproductive efficiency in livestock is a major driver of sustainable food production. The poorly understood process of ruminant conceptus elongation (a) prerequisites maternal pregnancy recognition, (b) is essential to successful pregnancy establishment, and (c) coincides with a period of significant conceptus mortality. Conceptuses at five key developmental stages between Days 8–16 were recovered and cultured in vitro for 6 h prior to conditioned media analysis by untargeted ultrahigh-performance liquid chromatography tandem mass spectroscopy. This global temporal biochemical interrogation of the ex situ bovine conceptus unearths two antithetical stage-specific metabolic phenotypes during tubular (metabolically retentive) vs. filamentous (secretory) development. Moreover, the retentive conceptus phenotype on Day 14 coincides with an established period of elevated metabolic density in the uterine fluid of heifers with high systemic progesterone—a model of accelerated conceptus elongation. These data, combined, suggest a metabolic mechanism underpinning conceptus elongation, thereby enhancing our understanding of the biochemical reciprocity of maternal–conceptus communication, prior to maternal pregnancy recognition.

Authors: Allin Kristine H , Jacobsen Rikke K , Ungaro Ryan C , Colombel Jean-Frederic , Egeberg Alexander , Villumsen Marie , Jess Tine 
Published: February 2021

Abstract

Background and Aims
The aim of this study was to examine the risk of new-onset inflammatory bowel disease [IBD] following bariatric surgery.

Methods
We conducted a nationwide population-based prospective cohort study of the entire Danish population 18 to 60 years of age, alive, and residing in Denmark, from 1996 to 2018. Bariatric surgery was included as a time-dependent variable, and Cox proportional hazards regression models were used to estimate hazard ratios [HRs] of IBD. We used a model adjusting for age, sex, and birth cohort and a multifactor-adjusted model additionally including educational status and number of obesity-related comorbidities.

Results
We followed 3 917 843 individuals of whom 15 347 had a bariatric surgery, for development of new-onset IBD. During 106 420 person-years following bariatric surgery, 100 IBD events occurred [incidence rate 0.940/1000 person-years]. During 55 553 785 person-years without bariatric surgery, 35 294 events of IBD occurred [incidence rate 0.635/1000 person-years]. This corresponded to a multifactor-adjusted hazard ratio [HR] of 1.15 (95% confidence interval[CI], 0.94–1.40) for IBD. Multifactor-adjusted HRs of Crohn’s disease [CD] and ulcerative colitis [UC] were 1.85 [95% CI, 1.40–2.44] and 0.81 [95% CI, 0.61–1.08], respectively. Among women, the multifactor-adjusted HR for CD was 2.18 [95% CI, 1.64–2.90]. When limiting the study population to individuals with a diagnosis of overweight/obesity, bariatric surgery remained associated with increased risk of CD, multifactor-adjusted HR 1.59 [95% CI, 1.18–2.13].

Conclusions
This nationwide cohort study shows that bariatric surgery is associated with increased risk of development of new-onset CD, but not of UC. The underlying mechanisms remain elusive.
Presence of Native and Non-native Ants Linked to Lower Emergence Success of Loggerhead Sea Turtle Nests: Implications for Management
Authors: Braman Charles A , Pfaller Joseph B , Williams Kristina L , Forschler Brian T 
Published: February 2021

Abstract
Ants have been suggested as one of many population pressures sea turtles face potentially affecting nesting-beach survival of eggs and hatchlings. However, little is known about the extent to which ants act as incidental or primary mortality factors. Most research has focused on New World fire ants (genus Solenopsis), with confirmed records of other ant species interactions with sea turtle nests in situ being rare. Our study documented the ant species associated with loggerhead sea turtle Caretta caretta (Linnaeus) (Testudines: Cheloniidae) nests in Georgia and determined if ant presence was linked to lower hatching or emergence success. Samples (n = 116) collected from sea turtle nests on eight islands contained 14 ant species including Solenopsis invicta Buren (Hymenoptera: Formicidae), the red imported fire ant, which was the most common ant species encountered. Ant presence was not correlated with lower hatching success, but when other known disturbances were removed, correlated with significantly lower nest emergence success (P &lt; 0.0001). Logistic modeling suggests that proximity of sea turtle nests to the primary dune significantly increases risk of ant predation on hatchling sea turtles. Population managers can reduce this risk by maintaining a 1-m buffer shoreward between dune vegetation and relocated sea turtle nests. Our results suggest that ants may exert a density-dependent pressure on nesting sea turtle populations and call for additional investigations to determine if managing native and invasive ants augments other efforts to improve hatchling survival.

Abstract

Aims
In low-gradient aortic stenosis (LGAS), the high valvulo-arterial impedance observed despite low valvular gradient suggests a high vascular load. Thoracic aortic calcifications (TACs) and valvular aortic calcifications (VACs) are, respectively, surrogates of aortic load and aortic valvular gradient. The aim of this study was to compare the respective contributions of TAC and VAC on 3-year cardiovascular (CV) mortality following TAVI in LGAS vs. high-gradient aortic stenosis (HGAS) patients.

Methods and results
A total of 1396 consecutive patients were included. TAC and VAC were measured on the pre-TAVI CT-scan. About 435 (31.2%) patients had LGAS and 961 (68.8%) HGAS. LGAS patients were more prone to have diabetes, coronary artery disease (CAD), atrial fibrillation (AF), and lower left ventricular ejection fraction (LVEF), P&lt;0.05 for all. During the 3 years after TAVI, 245(17.8%) patients experienced CV mortality, 92(21.6%) in LGAS and 153(16.2%) in HGAS patients, P=0.018. Multivariate analysis adjusted for age, gender, diabetes, AF, CAD, LVEF, renal function, vascular access, and aortic regurgitation showed that TAC but not VAC was associated with CV mortality in LGAS, hazard ratio (HR) 1.085 confidence interval (CI) (1.019–1.156), P=0.011, and HR 0.713 CI (0.439–1.8), P=0.235; the opposite was observed in HGAS patients with VAC but not TAC being associated with CV mortality, HR 1.342 CI (1.034–1.742), P=0.027, and HR 1.015 CI (0.955–1.079), P=0.626.

Conclusion
TAC plays a major prognostic role in LGAS while VAC remains the key in HGAS patients. This confirms that LGAS is a complex vascular and valvular disease.
