Abstract
Improving marine safety of transportation is very important. The Bali Straits is a strategic area that connects between Java island and Bali island. This strait is categorized as a busy strait. Bali straits also categorized as a tourist area. The strait separates Java Island (in the west) and Bali Island (in the east). The Bali Strait is connected by ferry services to the Gilimanuk Port (in Bali) and the Ketapang Port (in Java). Marine traffic safety has given benefit for life. Total ferry operating in one day is around 32 ferries. In this study we have analyzed and evaluated risk of maritime traffic. FMEA method was developed in this paper. RPN value was determined by considering the variables O (occurrence), S (severity) and D (detection). Development of scenario was established to analyze the behavior of the accident risks, with respect to changes in the surrounding traffic condition, meteorological and geographical.

Authors: Prastowo H , Pitana T , Kusuma H P 
Published: September 2020

Abstract
Global shipping accounts for nearly one million tonnes of CO2 emissions annually during 2013 – 2015 period, and could grow 50%-250% by 2050 if the condition is unchanged. The International Maritime Organization (IMO) as the specialized agency responded to this issue written in MEPC.304(72) about strategy of reducing green house gas (GHG) emissions from ships. Energy Efficiency Operational Indicator (EEOI) is a monitoring tool based on CO2 emissions proposed by IMO written in MEPC.282(70). The purpose of this research is to evaluate factors influencing the results of EEOI. Estimation of fuel oil consumption using proposed methods by Bialystocki and Konovessis and Moreno-Gutiérrez, et al. are compared with actual fuel oil consumption resulted in average error of 20.44% and 15.45%. The EEOI results is 0.000905 ton CO2/TEU-nm for MV Meratus Benoa and 0.000509 ton CO2/TEU-nm for MV Meratus Bontang. Benchmarking process using the same voyage route revealed that MV Meratus Benoa is less efficient than MV Meratus Bontang. MV Meratus Benoa carried less average cargo than MV Meratus Bontang, while having more average fuel oil consumption. Proposed improvement for better EEOI results is improving the cargo management especially for MV Meratus Benoa and evaluation in ship’s operational setting for any specific sea conditions.

Authors: Ibadah A S , Saptarini D 
Published: September 2020

Abstract
Mangroves are vegetation that have morphological adaptation in root type to grow in coastal area. This root type adaptation makes mangrove provide habitat for various fauna. In this study we compare fish abundance in three types of mangrove habitat (vegetated area, mangrove fringe area and mangrove sea area) in urban mangrove estuaries area of Wonorejo, Surabaya – Indonesia. A total of 26 species fish species in 17 families were collected. In terms of number of species per family, Engraulidae was the most diverse (7 species), followed by Carangidae (3 species). ANOVA analysis showed that fish abundance varies significantly in three different mangrove habitat types. Habitat type that have highest diversity of fish is mangrove sea area, followed by fringe mangrove area and vegetated area. Some specific species exclusively recorded in certain habitat type, 10 species occurring exclusively in the mangrove sea area, 7 species occurring exclusively in the mangrove fringe area but there is no fish species that exclusively occur in vegetated area. The results indicate that urban mangrove estuary area in Wonorejo has potentially provide habitat for fish, but this potency was combined by a connection of vegetated area, mangrove fringe area and mangrove sea area, not only by vegetated area.

Abstract
Globalization had increased global economic activity, including production, trade and distribution activities in developing countries, especially in Asia. The increasing of trade traffic and cargo transportation in archipelago country like Indonesia, requires the utilization of sea lanes. This study was aimed to present the suitability of ship design to be passengers transportation in Berau Regency, East Kalimantan, Indonesia. The proposed design should be in accordance with the conditions of Berau which has 6 districts crossed by the river which still lack of transportation facilities. This research proposed an optimal ship design that can be used as a reference for renewable ships in Berau waters. This study produced a watershed design analysis concept as part of the reference and boundary dimensions of the ship. The obtained main size of the ship using linear regression method was total length of 12.5 meters, 3 meters wide, 1.5 meters high, and 0.6 meters full of water. Resistance analysis using the Savitsky method showed the engine capacity of 2x150 pk with a service speed of 25 knots. Maximum speed of 30 knots with a distance of 57.32 mill can be reached with 2 hours service speed and 1 hour 40 minutes at a maximum speed of 30 knots with the resistance value 12.8 kN. The total estimated budget for the production of this ship was Rp 1.773.656.800. This design may be adopted as an integrated reference for the procurement of transportation facilities for passenger ships, especially in the Berau river.
Risk Assessment of Subsea pipeline using standard DNVGL-RP-F107
Authors: Waskito R , Artana K B , Pratiwi E 
Published: September 2020

Abstract
To avoid fuel scarcity, exploitation activities must be carried out to meet the needs of oil in Indonesia. In the process of oil exploitation, facilities are needed to carry out a fluid transfer system from one place to another. One way to carry out the process of fluid transfer at an offshore location is the use of an underwater piping system. However, in the transfer of fluid from one place to another there is a danger that can cause failures in the pipeline system. For example, if an underwater gas pipeline is in the shipping lanes, international and national vessels, there is a possibility of danger that could occur due to a third party. In making this thesis the risk assessment is assessed using the DNVGL-RP-F107 standard. Based on the DNVGL-RP-F107 standard, hazards that may occur in underwater gas pipelines are hazards caused by falling or dropped anchors, anchored dragged pipes and destroyed ship (ship sinking). In risk assessment using the DNVGL-RP-F107 standard, the consequence analysis conducted refers to the damage to the subsea pipeline. After getting the analysis results from the index values that have been made, proceed with making a risk representation using the Risk Matrix. Pipelines that have been evaluated and representations in the risk matrix are in the ALARP zone (as low as reasonably practical) and in acceptable zone.

Published: September 2020

Abstract
Maintenance activities conduct to manage and preserve assets integrity. Risk assessment is used to develop interval inspection hence, maintenance strategy can arrange perfectly. On the other hand, prescriptive inspection is still used as the main consideration to determine the inspection schedule. The consequence is an ineffective inspection activity. Past expert judgement was a major consideration in resulting prescriptive schedule which probably has not been reassessed and updated at present. A quantitative assessment can cover the probability and consequence of failure through a detailed assessment. The assessment takes time to be developed which complex systems and formulas are adjusted to the actual condition. Somehow, this task might be conducted by an external party who has expert knowledge. Therefore, within this schedule vacancy, any deterioration might occur in the system. A qualitative assessment can be done to estimate risk. Local engineers, who have basic knowledge of corrosion and other damage factors, can do the qualitative assessment. The result shall update the previous prescriptive methods. In processing qualitative assessment, fuzzy methods are chosen due to their ability to cover linguistic tasks and numerical value. In this paper, fuzzy logic was used to determine the probability of failure of equipment. The result was compared to API 581 RBI assessment. At the latter, risk value from both methods was evaluated to determine the inspection interval. Both types of equipment have close results from inspection interval calculation. Mostly, the inspection interval from the fuzzy method was earlier than RBI methods. From this calculation, the fuzzy results can be used as an estimation for the local engineer’s consideration to determine any inspection based on qualitative assessment. If the result compared with an 8-years prescriptive inspection interval, inspection interval from qualitative assessment earlier conducted. It means asset integrity could be maintained more precisely. The equipment is pressure vessels in the utility area to support the boiler system from an Indonesian oil and gas company.
An implementation of Three-Dimensional Multi-Component Mooring Line Dynamics Model for Multi-Leg mooring line configuration
Authors: Hermawan Y A , Furukawa Y 
Published: September 2020

Abstract
Multi-component mooring line (MCML) system is widely used and expected to be escalated for deep water mooring operation since it has several advantages comparing with conventional mooring line. The modelling of MCML involving its dynamic effects is strongly required to predict the dynamic behaviours of the mooring line precisely. In this paper, a proposed three-dimensional dynamics model of MCML system is presented and implemented to single point multi-leg mooring line configuration operated in deep water condition. An extending three-dimensional lumped mass method is elaborated to develop the model while the combination of Manoeuvring Modelling Group (MMG) and conventional floating body motion equations is used to perform simultaneous motion between floating structure and mooring lines. The simultaneous motion is performed with respect to wind, wave, and current. The motion of the floating structure and mooring line as well as mooring line tension can be analysed properly by using the presented model. The simulation results of the model show reasonable results for both floating structure and mooring line.

Abstract

Objectives
Serologic testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has experienced a changing landscape of available assays coupled with uncertainty surrounding performance characteristics. Studies are needed to directly compare multiple commercially available assays.

Methods
Residual serum samples were identified based on SARS-CoV-2 reverse transcription polymerase chain reaction (RT-PCR) testing, clinical test results, and collection dates. Serum samples were analyzed using assays from four different manufacturers: DiaSorin anti–SARS-CoV-2 S1/S2 IgG, EUROIMMUN anti–SARS-CoV-2 IgG ELISA, Roche Elecsys anti–SARS-CoV-2, and Siemens SARS-CoV-2 Total antibody assays.

Results
Samples from SARS-CoV-2 RT-PCR–positive patients became increasingly positive as time from symptom onset increased. For patients with latest sample 14 or more days after symptom onset, sensitivities reached 93.1% to 96.6%, 98.3%, and 96.6% for EUROIMMUN, Roche, and Siemens assays, respectively, which were superior to the DiaSorin assay at 87.7%. The specificity of Roche and Siemens assays was 100% and superior to DiaSorin and EUROIMMUN assays, which ranged from 96.1% to 97.0% and 86.3% to 96.4%, respectively.

Conclusions
Laboratories should be aware of the advantages and limitations of serology testing options for SARS-CoV-2. The specificity and sensitivity achieved by the Roche and Siemens assays would be acceptable for testing in lower-prevalence regions and have the potential of orthogonal testing advantages if used in combination.

AbstractAcetyl-dl-leucine is a derivative of the branched chain amino acid leucine. In observational clinical studies, acetyl-dl-leucine improved symptoms of ataxia, in particular in patients with the lysosomal storage disorder, Niemann-Pick disease type C1. Here, we investigated acetyl-dl-leucine and its enantiomers acetyl-l-leucine and acetyl-d-leucine in symptomatic Npc1−/− mice and observed improvement in ataxia with both individual enantiomers and acetyl-dl-leucine. When acetyl-dl-leucine and acetyl-l-leucine were administered pre-symptomatically to Npc1−/− mice, both treatments delayed disease progression and extended life span, whereas acetyl-d-leucine did not. These data are consistent with acetyl-l-leucine being the neuroprotective enantiomer. Altered glucose and antioxidant metabolism were implicated as one of the potential mechanisms of action of the l-enantiomer in Npc1−/− mice. When the standard of care drug miglustat and acetyl-dl-leucine were used in combination significant synergy resulted. In agreement with these pre-clinical data, when Niemann-Pick disease type C1 patients were evaluated after 12 months of acetyl-dl-leucine treatment, rates of disease progression were slowed, with stabilization or improvement in multiple neurological domains. A beneficial effect of acetyl-dl-leucine on gait was also observed in this study in a mouse model of GM2 gangliosidosis (Sandhoff disease) and in Tay-Sachs and Sandhoff disease patients in individual-cases of off-label-use. Taken together, we have identified an unanticipated neuroprotective effect of acetyl-l-leucine and underlying mechanisms of action in lysosomal storage diseases, supporting its further evaluation in clinical trials in lysosomal disorders.

Abstract

Background
The human T-cell leukemia virus type 1 (HTLV-1) subtype c is endemic to central Australia. We report the first large-scale, community-based, health survey of HTLV-1 and its disease associations in this setting.

Methods
Aboriginal community residents aged &gt;2 years in 7 remote communities were invited to do a health survey that included a questionnaire, spirometry, and clinical examination by a physician blinded to HTLV-1 status, clinical records, and spirometry results. Blood was drawn for HTLV-1 serology and proviral load (PVL). Pulmonary disease was assessed clinically and spirometrically and, where records were available, radiologically after the clinical assessment. Associations between specific diseases and HTLV-1 status were determined using logistic regression, adjusting for available confounders.

Results
Overall, 579 residents (164 children aged 3–17 years; 415 adults) were examined (37.7% of the estimated resident population). HTLV-1 prevalences for children and adults were 6.1% and 39.3%, respectively. No associations were found between HTLV-1 and any assessed clinical condition among children. Chronic pulmonary disease and gait abnormalities were more common among adults with HTLV-1 infection. Adjusted odds ratios among participants with PVL ≥1000 per 105 peripheral blood leukocytes were 7.08 (95% confidence interval [CI], 2.67–18.74; P &lt; .001), 9.81 (95% CI, 3.52–27.35; P &lt; .001), and 14.4 (95% CI, 4.99–41.69; P &lt; .001) for clinically defined chronic pulmonary disease, moderate-severe expiratory airflow limitation, and radiologically determined bronchiectasis/bronchiolitis, respectively, and 5.21 (95% CI, 1.50–18.07; P = .009) for gait abnormalities.

Conclusions
In the first study of HTLV-1 disease associations based on community recruitment and blinded assessment, HTLV-1 infection was strongly associated with pulmonary disease and gait abnormalities.

Abstract
This systematic review describes the influence of co-occurring substance use on the effectiveness of opiate treatment programs. MEDLINE/PubMed, Embase, PsychINFO, and the Cumulative Index to Nursing and Allied Health Literature were searched from database inception to November 28, 2018, to identify eligible opioid treatment studies in the United States that assessed the relationship between co-occurring substance use and treatment outcome (i.e., opioid abstinence and treatment retention). A total of 34 eligible studies were included. Overall, co-occurring substance use was associated with negative treatment outcomes regardless of intervention type. However, patterns varied by substance and intervention type. In particular, co-occurring use of cocaine or marijuana with opioids was associated with reduced treatment retention and opioid abstinence regardless of intervention type. Co-occurring use of amphetamines, compared with no use or reduced use of amphetamines, decreased treatment retention. Co-occurring use of alcohol was both positively and negatively associated with treatment outcomes. One study reported a significant positive association between sedative use and opioid abstinence. Generally, findings suggest that combined interventions reported better health outcomes compared with pharmacological or behavioral intervention studies alone. The findings of this review emphasize the need to comprehensively study and address co-occurring substance use to improve opiate treatment programs.
Assessing tree crown volume—a review

Published: September 2020

Abstract
Tree crown volume is a fundamental tree characteristic. It correlates to forest biomass production and most relevant ecosystem and environmental functions, such as carbon sequestration and air pollution reduction. When researching these relationships, it is necessary to clearly define and then quantify tree crown variables in a both accurate and operational manner. In this paper, we review the reported literature on the assessment of tree crown volume. First, we compile the varying definitions of crown volume and other tree crown variables that may be used as inputs to quantify crown volume. Then, we examine the data sources for quantifying these variables, including field measurements, terrestrial photographs, aerial photographs and laser scanning. Furthermore, we compare the published approaches on translating these crown variable measurements into tree crown volume. These approaches include the approximation of simple geometric solids, approaches of computational geometry and voxelization. We also compare the reported accuracies and major challenges of these approaches. From this literature review, the reader may craft a suitable approach for the assessment of crown volume.

Published: September 2020

Summary
Green space is important for health, yet, objective research on children’s use of green space is sparse. This study aimed to objectively assess children’s use of green space in both public and private settings during their summer leisure time, using wearable cameras. Images from cameras worn by 74 children were analysed for green space use over 4 days. Children spent an average of ∼1/10 h of leisure time in green space in the summer months, were physically active 68%, and with others 85%, of the time. Green spaces are important places for children’s health because they are places they frequent and places where they are physically active and socialize. Wearable cameras provide an effective method for objective assessment of green space use.
