Published: September 2020

Abstract
Using electron beam manipulation, we enable deterministic motion of individual Si atoms in graphene along predefined trajectories. Structural evolution during the dopant motion was explored, providing information on changes of the Si atom neighborhood during atomic motion and providing statistical information of possible defect configurations. The combination of a Gaussian mixture model and principal component analysis applied to the deep learning-processed experimental data allowed disentangling of the atomic distortions for two different graphene sublattices. This approach demonstrates the potential of e-beam manipulation to create defect libraries of multiple realizations of the same defect and explore the potential of symmetry breaking physics. The rapid image analytics enabled via a deep learning network further empowers instrumentation for e-beam controlled atom-by-atom fabrication. The analysis described in the paper can be reproduced via an interactive Jupyter notebook at https://git.io/JJ3Bx

Abstract
Amongst assorted regio-selective and targeted oral drug delivery strategies accepted for the gastro-retentive drug delivery system (GRDDS), the floating drug delivery system (FDDS) holds a major share as clinically accepted formulations. The major objective of the present investigation was to explore the silk industry waste protein, silk fibroin (SF) as a possible electrospun nanocarrier for the FDDS. In a nutshell, electrospinning (ES) is one of the flexible and astonishing strategies for the fabrication of porous electrospun nanofibers (NFs), which offers the potential to amend the floating profile, dissolution rate, solubility, and release patterns of the drug, etc as per compendial requirements. Looking at the prospects of floating SF-NFs preparation, we have isolated and lyophilized the SF from industrial waste cocoons and prepared drug-loaded SF single polymer nanofibers (SPN). Lafutidine (LF) being a good candidate for GRDDS selected as a model drug, which is an excellent proton pump inhibitor, mainly used in the treatment of gastric ulcers. Finally, the obtained LF loaded SF-NFs (LF-SF-NFs) were successfully analyzed for physicochemical characteristics, porosity, swelling index, antioxidant activity, mucoadhesion strength, floating properties, enzymatic degradation, and accelerated stability study, etc. Further, these LF-SF-NFs were evaluated for percent drug content, weight variation, in-vitro dissolution in 0.1 N hydrochloric acid (HCl, pH:1.2) and fasted state simulated gastric fluid (FSSGF), and accelerated stability study. It has shown significant floating time >18 h, about 99% ± 0.58% floating buoyancy with sustained release up to 24 h. LF-SF-NFs showed good compatibility, entrapment efficiency, antioxidant activity, mucoadhesion strength, enzymatic degradation, and long term stability. Soon, the essential floating and drug release profiles can claim single polymer (SF) based electrospun protein NFs as a possible novel oral nanocarrier for FDDS.
Thermodynamics of non-elementary chemical reaction networks
Authors: Avanzini Francesco , Falasco Gianmaria , Esposito Massimiliano 
Published: September 2020

Abstract
We develop a thermodynamic framework for closed and open chemical networks applicable to non-elementary reactions that do not need to obey mass action kinetics. It only requires the knowledge of the kinetics and of the standard chemical potentials, and makes use of the topological properties of the network (conservation laws and cycles). Our approach is proven to be exact if the network results from a bigger network of elementary reactions where the fast-evolving species have been coarse grained. Our work should be particularly relevant for energetic considerations in biosystems where the characterization of the elementary dynamics is seldomly achieved.

Published: September 2020

Abstract
The second post-Newtonian solution for the equatorial motion of a test particle in the Kerr spacetime is derived under the harmonic coordinates. The effects of the spin-induced quadrupole on the equatorial motion are obtained. The solution is formulated in terms of the Kerr black hole’s mass and spin, as well as the particle’s orbital energy and angular momentum.

Electric Dipole Moment Measurements at Storage Rings
Authors: Pretz J 
Published: September 2020

Abstract
Electric Dipole Moments (EDM) of elementary particles, including hadrons, are considered as one of the most powerful tools to discover CP-violation beyond the already known sources of the Standard Model. Such CP-violating mechanisms are required to explain the dominance of matter over anti-matter in our universe.
Up to now experiments concentrated on neutral systems. Storage rings offer the possibility to measure EDMs of charged particles by observing the influence of the EDM on the spin motion. Different options and a strategy towards storage ring EDM measurements will be discussed.

Abstract

Background. Exposure to high air temperature in late pregnancy is increasingly recognized as a risk factor for preterm birth (PTB). However, the combined effects of heatwaves with air pollution and green space are still unexplored. In the context of climate change, investigating the interaction between environmental factors and identifying communities at higher risk is important to better understand the etiological mechanisms and design targeted interventions towards certain women during pregnancy. Objectives. To examine the combined effects of heatwaves, air pollution and green space exposure on the risk of PTB. Methods. California birth certificate records for singleton births (2005–2013) were obtained. Residential zip code-specific daily temperature during the last week of gestation was used to create 12 definitions of heatwave with varying temperature thresholds and durations. We fit multi-level Cox proportional hazard models with time to PTB as the outcome and gestational week as the temporal unit. Relative risk due to interaction (RERI) was applied to estimate the additive interactive effect of air pollution and green space on the effect of heatwaves on PTB. Results. In total, 1 967 300 births were included in this study. For PM2.5, PM10 and O3, we found positive additive interactions (RERIs >0) between heatwaves and higher air pollution levels. Combined effects of heatwaves and green space indicated negative interactions (RERIs <0) for less intense heatwaves (i.e. shorter duration or relatively low temperature), whereas there were potential positive interactions (RERIs >0) for more intense heatwaves. Conclusion. This study found synergistic harmful effects for heatwaves with air pollution, and potential positive interactions with lack of green space on PTB. Implementing interventions, such as heat warning systems and behavioral changes, targeted toward pregnant women at risk for high air pollution and low green space exposures may optimize the benefits of reducing acute exposure to extreme heat before delivery.

Authors: Dinariyana A A B , Avesina M A , Sambodho K , Fahrirozan F 
Published: September 2020

Abstract
Lombok Strait is one of the water areas that designated for international shipping lanes since it has been adopted as the Indonesia Archipelagic Sea lane (IASL) II in 1998. Foreign-flagged ships passing through the strait from southbound to northbound and vice versa. Along with being an archipelagic sea lane, the strait also occupied by high-density crossing traffic connecting Bali and Lombok islands. This crossing traffic mainly dominated by passenger ferry Ro-Ro and pleasure ships as both Bali and Lombok islands are well known as tourist destinations. Aside from being a tourist destination, several islands around the Lombok Strait are also dedicated to Marine Protected Areas (MPA). There are two areas designated for MPA by the Indonesian government in the vicinity of Lombok Strait; Nusa Penida on the west side of IASL II and Gili Matra on the east side. The traffic condition allows the potential for collisions on ships passing through and crossing the Lombok Strait which is very likely caused by navigation errors, human errors, weather conditions, and other technical problems. This study aims to determine the collision risk analysis in terms of annual frequency of collision and grounding as well as the potential dispersion of oil that occurs in the event of a ship collision near the MPA of Nusa Penida. Based on one-year traffic data and forecasted to 20 years, collision and grounding frequencies analysis was conducted using iWRAP method. The analysis found that annual frequency including head-on, overtaking, crossing, merging, bend, and grounding is 4.73×10-1. In addition to the frequency of collisions, oil spill dispersion simulations were carried out using GNOME under two different conditions wind and sea current directions; wind and sea currents that heading to the Northwest, and Southwest. Given a scenario of collision occurred close to Nusa Penida island involving tanker ship that resulting hull damage and oil spill while the wind and sea current directed to Southwest, simulation resulting that oil spill will disperse and polluting MPA of Nusa Penida.

Published: September 2020

Abstract
Subsea pipeline is one of alternatives to transport gas from offshore platform to onshore production facility. In Surabaya West Access Channel (APBS), there are some subsea gas pipelines lay on seabed. Maintenance of subsea pipeline should be carried out to ensure the sustainability of gas delivery, such as replacement of Sacrificial Anode Cathodic Protection. Since the replacement activity includes operation of Diving Support Vessel (DSV) along the subsea pipeline, it could potentially induce ship collision between DSV with other ships passing through the channel. This paper carried out a risk assessment of ship collision during replacement of anodes of subsea gas pipeline in APBS. The frequency of ship collision is analyzed by using Computerized Risk Assessment of Shipping Hazards (CRASH) and Traffic Based Models. The consequence is analyzed using Finite Element Method (FEM) which results the impact of collision on the hull of ship. Deformation of hull requires cost of repair which further becomes the outcome of consequences analysis. The risk is represented in the risk matrix which adopted from the Australian Standard Guidelines. The result shows that frequency of collision is 0.1342 per year while the consequences analysis results US$ 2,160,077 which required for repair. The risk representation shows that the anodes replacement has an extreme risk level based on the Australian Standard Guidelines. Further preventive measures are required to reduce the level of risk to be medium or low level of risk.
Maritime Aerial Surveillance: Integration Manual Identification System to Automatic Identification System

Published: September 2020

Abstract
Indonesia has an almost 100,000 km coastline with a very busy shipping and maritime activity. To regulate ship traffic, the government relies on Vessel Traffic Service (VTS) and Automatic Identification System (AIS). VTS functions like Air Traffic Control (ATC) in commercial flight traffic control, which relies on radio conversations to communicate between VTS officers and the ship’s captain. While AIS uses transponders mounted on ships to send ship position data which are then displayed virtually in the form of ship icons. However, both VTS and AIS do not display the real picture of the ship’s description. VTS, AIS Receiver and Electronic Chart Display Information System (ECDIS only presented the ship’s movement through radio voice and the ship’s icon on the monitor. With Reporting Interval from 2 seconds until 180 seconds. It is because AIS is designated to send data every 2 – 180 seconds depending on vessel moving status. But within the reporting interval 180 seconds, the condition of the ship can change a lot. This is the motivation of this paper was written to propose monitoring vessel traffic through an aerial flying camera that can monitor real ships with cinematic class video quality in real-time because the video latency can be achieved faster than 10 milliseconds. The research is conduct by simultaneous monitoring the marine traffic through web and launching the flying camera at the same time and place. And the results is very surprises, because many ship found not AIS detected compare to flying camera results video.
Study of Green-Ship Routing Problem (G-VRP) Optimization for Indonesia LNG Distribution
Authors: Siahaan Joshua J A , Pratiwi E , Setyorini P D 
Published: September 2020

Abstract
Natural gas is distributed around Indonesia mainly to be used as fuel in electrical power plants. The increase of consumption of electricity in Indonesia is on average of 6.8% annually. In response, the government considers developing gas power plants in central parts of Indonesia. As an archipelago, Indonesia depends heavily in connectivity between islands which is obviously supported by seaborne vessels or ships. These facts make the LNG transportation a complex matter in Indonesia. The distribution of LNG by ship can be designed as a hub and spokes liner shipping. A single hub and spokes network has one hub port and several feeder ports. In LNG supply chain network, the hub is the liquefaction plant and the feeder ports are receiving terminals. Various optimization methods have been established to optimally utilize a fleet. Other than the cost-efficiency, there are other considerations in optimizing the fleet. One of the current trending considerations is the emission. In the past few years, concern about environment has been increasing. IMO released a number based on research that shows that maritime transportation has 2.7% contribution to global anthropogenic emission. The aim of this research is to determine the optimal fleet and its routes of an LNG shipping to minimize the CO2 emission while also minimizing the cost of LNG distribution in central part of Indonesia that covers South Eastern Sulawesi. Demand points are the power plants of Kendari, Baubau, Selayar, Bombana, and Kolaka with a total of 828 m3 daily needs for LNG. The cost calculation was done in a G-VRP framework which took emission into account. A method called Bin Packing Problem within the context of Vehicle Routing Problem was established to minimize the total distribution cost and emission for each cluster. After acquiring the best route and fleet option, this research compared and analysed the benefits of using conventional diesel engine and a dual fuel diesel engine scenario for the chosen vessel. The result of this optimization study shown that the transportation shall use one unit of type-A ships with a capacity of 1100 m3 for the routes Ambon-Bombana-Kolaka Utara-Ambon. And two units of type-B ship with a capacity of 2500 m3 for Ambon-Kendari-Ambon and Ambon-Baubau-Selayar-Ambon route. All ships use LNG as fuel. The total expense for this scenario is $2,980,768.63 and the use of dual fuel diesel engine instead of a conventional diesel engine for the ships can reduce the total costs by $2,434,348.97 or 44.95%.

Published: September 2020

Abstract
Indonesian Navy continues to build 60 Meter Fast Missile Boat (KCR-60) is one of them and acts as a fast patrol boat and high-speed combatant ship in the archipelago warfare. The bow of the ship is an important part in the design of the ship as well as the bow of the KCR-60, because it is the most stressed, stressed from the waves, with the bow design that has a bow profile like an axe, the slender shape of the waterline is able to reduce the impact waves, increase the efficiency of the inflow rate, reduce the resistance of the vessel received so increase a better speed. This study changed the design of the Conventional Bow KCR-60 into the Axe Bow design concept with numerically calculated the total resistance of the Bow Bow design using the Holtrop method and performed a comparative analysis with the computing program MARIN DESPPC 1999 and Maxsurf Resistance V8i software. The results of this study found the total resistance value of KCR-60 Axe Bow type at 28 Knots speed was 364.2 KN and Conventional Bow type was 374.5 KN, the difference was 10.3 kN or 2.75% smaller than the Conventional Bow type in the analysis comparison of Maxsurf Resistance V8i software. For comparative analysis of the MARIN DESPPC 1999 program the total resistance value of the KCR-60 Axe Bow concept at 28 Knots is 283.6 KN and the Conventional Bow type is 288.1 KN, the difference is 4.5 KN 1.56% smaller than the Conventional type.
Near Miss Detection for Encountering Ships in Sunda Strait
Authors: Prastyasari F I , Shinoda T 
Published: September 2020

Abstract
Sunda Strait has played an essential role to the Indonesian marine transportation. Safety of navigation is one issue that often leads to an accident, especially ship collision. A collision risk assessment in a waterway is critical not only to predict the probability of collision accident but also to understand its consequences to human life, shipping company, as well as to the environment. However, it could be hard to evaluate the accident due to the scarcity of real accident data. Thus, a near miss analysis can be considered as an equivalent substitute. A one-week of Automatic Identification System (AIS) data is taken as the sample to test the methodology proposed in this paper. The target area of the near miss analysis discussed in this paper is TSS area in Sunda Strait. To categorise the encounter as a safe or unsafe encounter, this paper utilises the closest point of approach (CPA) as the indicator and it contains two parameters, the distance to CPA (DCPA) and the time to CPA (TCPA). Four values of DCPA and TCPA are used as the threshold, those are introduced by Park, Fukuto and Imazu, Goodwin, and Limbach. In this time range, 135929 sample data are collected, but only 92,379 points from 276 ships are found inside the target area. The number of situations that are categorized as near miss encounters (NNM) for each threshold are 1668, 5870, 9370, and 13549, respectively. The combined threshold is proposed to adjust with the condition of Sunda Strait and produce a result with 9,946 points detected as near miss encounter.

Abstract
Mangrove ecosystems are resources of landscapes, flora, fauna, and local communities that interact with each other. Mangrove ecosystems have important ecological, economic and social functions for coastal development. Conservation is a means of involving the community in mangrove recovery and management activities as a preservation effort. This paper examines the potential of mangrove ecosystems in the southern coast of Bangkalan as a conservation area. The fact, mangrove ecosystems have a pressure that decreased area significantly. Data collection used the quadratic transect method and satellite image analysis. Mangroves on the southern coast of Bangkalan have increased area over the past 10 years. Mangrove vegetation found consisted of 4 families and 8 species. There are also found fauna i.e. insects, snakes, primates and birds. The observations indicated that conservation of mangrove forests on the southern coast of Bangkalan needs to be done. This effort can be supported by ecotourism activities which are expected to improve the community welfare.
