Published: October 2019

Abstract
A growing number of dielectric elastomer actuators have been proposed to build soft robots and soft electronic devices. However, it remains a big challenge to design soft bistable actuators. Most of existing bistable actuators based on soft materials generate either limited actuation range or unrepeatable actuation. In this article, we present a new bistable rotating mechanism using dielectric elastomer actuators, which exhibits a relatively large actuation angle range and repeatable motion. The mechanism is featured by an antagonistic structure with mechanical locks to create two symmetric stable configurations. We develop an analytical model to help design and explain the electromechanical behavior of the bistable rotating mechanism. Powered by the dielectric elastomer actuators, it shows fast response and large load capability. We build a binary manipulator to further demonstrate that the bistable rotating mechanism can provide a promising route for the design of binary systems.

Abstract
Single-photon laser enabled Auger decay (spLEAD) is an electronic de-excitation process which was recently predicted and observed in Ne. We have investigated it using bichromatic phase-locked free electron laser radiation and extensive angle-resolved photoelectron measurements, supported by a detailed theoretical model. We first used separately the fundamental wavelength resonant with the Ne+ 2s–2p transition, 46.17 nm, and its second harmonic, 23.08 nm, then their phase-locked bichromatic combination. In the latter case the phase difference between the two wavelengths was scanned, and interference effects were observed, confirming that the spLEAD process was occurring. The detailed theoretical model we developed qualitatively predicts all observations: branching ratios between the final Auger states, their amplitudes of oscillation as a function of phase, the phase lag between the oscillations of different final states, and partial cancellation of the oscillations under certain conditions.

Abstract
Time-temperature control is a critical issue in cold supply chain, so it is very important to be tracked. Time-temperature indicator (TTI) label is devices that visually show the cold-chain accumulated history, from both time and temperature fluctuation effects. Diffusion model of TTI’s indicator based on vegetable oils blend (VOB) has been investigated. The VOB indicators were made from canola oil (CA), soybean oil (SB), and olive oil (OV) that have blended with palm oil (PO). Nine formulas of indicator were designed in combination with the oils blendings i.e (A) PO:CA:SB, (B) PO:SB:OV, (C) PO:CA:OV and the combination of various ratio were (1) 50:40:10 %v/v, (2) 50:25:25 %v/v, and (3) 50:10:40 %v/v, then the blendings were added 0.25 %m/v red lake (C.I. 16255). The diffusion kinetics of this TTI indicators have tested on a waterproof photopaper material and storaged at 4, 18, 29, 37, and 40°C. The result present that the activation energy (Ea) values of indicators were about 28.925 – 40.646 kJmol−1. The B3 and C indicators have an Ea value which have matched with Ea value of a commercial diffusion-based TTI. Based on Arrhenius equation, the diffusion model (x, m) for B3, C1, C2, and C3, respectively were xB30.5=2t.e−4017(1/T)-4.4053, xC10.5=2t.e−4124.3(1/T)-4.0196, xC20.5=2t.e−4245.1(1/T)-3.7130, and xC30.5 = 2t.e−4888.9(1/T)-1.6641. Overall, the diffusion length of the indicators have significantly correlation with time-temperature changing and this diffusion model established can represented the diffusion behaviour of TTI’s indicators.

Abstract
Bengkulu Province is located on the west coast of Sumatra, part of Fisheries Management Area of Indonesia Republic (WPP-RI) 752 based on the Regulation of the Minister of Maritime Affairs and Fisheries No. 1 of 2009. The population living in this region consists of various tribes, both native and immigrants. Communities living in the coastal areas have a maritime culture characteristic which exists for a long time. At the era of globalization, these socio-cultural values are still a guide for some coastal communities. However, some people in certain regions is no longer pay attention and even ignore these social values. Therefore, with the socio-legal research method, this research attempts to examine the problem of how to strengthen and sustain the socio-cultural values as a legal culture of coastal communities in supporting the sustainable fisheries resources in the era of globalization. This paper is the result of research that shows how to support the sustainability of fisheries resources in the era of globalization. The result shows that it is necessary to strengthen the social values of marine culture as the legal culture of the people of the west coast of Sumatera. This can be done by giving recognition to the existence of the community legal culture through the establishment of legal regulation in the area concerned.

Published: October 2019

Abstract
In responsible and sustainable fisheries, marine resources should be exploited at optimum level in which potency, production and utilization level is known. This research was conducted to analysed potency, production and utilization level of pelagic fish in Ambon Island waters. Data for the analysis was obtained from the secondary data of Dinas Kelautan dan Perikanan Maluku province in the form of catch and effort for period 2005–2015 and then analysed by using Schaefer model. Estimated Maximum Sustainable Yield (MSY) was 103,513 tons with Total Allowable Catch (TAC) was 82,811 tons. Production of pelagic fish fluctuated but tended to increase due to increasing of fishing vessels and fishing gears. Catch per unit effort of purse seine and pole and line contributed more for the pelagic fish production than five other fishing gears. The utilization of pelagic fish resources in Ambon tended to increase with annual average 61.7% from TAC or 49.40% of MSY during the period of 2005-2015. In the last three years (2013-2015) the level of utilization increased significantly and has reached 98.31% from TAC or 78.65% of MSY which leads to fully exploitation. These results indicated that fishing effort should be maintained and monitored strictly to prevent over exploitation of pelagic fish resource.

Abstract
Abstract; Generally in Inner Ambon Bay (IAB) the sedimentation problem generate revamp of waters base configuration that influence IAB circulation process. We use model tool of MIKE 3 FM in this research to modeling three-dimensional hydrodynamics of process circulation and modeling of particle tracking. The purposes of the research are to analysis pattern of water mass circulation which is considering the baroclinic mode, to estimate the movement and pattern of cohesive sediment from every river inflow and to estimate the flushing as well as residence time of IAB. Simulation result of models is to represent circulation and particle movement in rainy season and dry season in IAB. In baroclinic mode the vertical eddy dominant happen in middle of IAB and in front of Poka-Galala sill. This vertical eddy is influenced by topography configuration and stratification water mass due to the rivers inflow. In model simulation of particle tracking the pattern of particle movement is dominant in middle of bay and along coastal of Lateri and Halong. The average of residence time and flushing time are 5 days and 9 days in rainy season, respectively while those in dry season are 2 days and 5 days respectively.

Abstract
Start Nickel (Ni) is common marine pollutant and derived from discharge of industries, mining and agriculture. Elevated Ni concentrations, could be harmful the organisms in marine environment such as corals reef. The sea anemones Exaiptasia pallida has been widely used for toxicity tests in the laboratory because it is easy to maintain and culture in contained aquarium conditions. To understand the pathway of uptake and storage of elevated Ni between the sea anemone host and symbiotic algae, and the model sea anemone E. pallida was exposed to three different Ni concentrations (500 xg/L, 1000 xg/L, 2000 xg/L) and control treatment over 9 days and 18 days. Ni accumulation was assessed in both the host anemone tissues and the Symbiodinium spp. The concentration of Ni was measured using Perkin Elmer NexION 300D ICPMS (Inductively Couple Plasma Mass Spectrophotometry) after sampel digestion. The statistical analysis was completed using R version 3.5.0 (R core team 2013) R Foundation for Statistical Computing, Vienne, Austria. The model was chosen by Akaike Information Criterion (AIC) after to comparing between model options. Shapiro-Wilks test was used to verify the normal distribution of the date set to be analysed.The overall result showed the accumulation of nickel was highest in Symbiodinium spp. (212.62 + 50.12 mg/Kg) after a 9 days exposure period in concentration 2000 xg/L while 18 days exposure period was less ( 129.66 + 31,94 mg/Kg) in concentration 2000 xg/L. The lower uptake of Ni in Symbiodinium spp. in the longer exposure time of 18 days compare to 9 days exposure might be due to the ability of Symbiodinium spp. to release the Ni through their metabolism or the Ni dose may have inhibited normal function of the algae, although the accumulation of both times period was significantly higher than the control treatments. Meanwhile, host anemones accumulated 77.43 + 6.28 mg/Kg Ni over 9 days exposure period and the 2000 xg/L treatment and increased after 18 days exposure in concentration 2000 xg/L (45.54 + 4.12 mg/Kg).The result of these finding highlight the importance of understanding the metal accumulation in host and cnidarian. This is particularly important if these species are used in biomonitoring studies where bleaching may occur due to stress, but may in effect be a depuration pathway for metal load, masking the biological uptake and interaction between metal and organisms.

Abstract
The Holothurian is one of the echinoderms which has well known as the sea cucumber. The coastal communities in Maluku often harvest the sea cucumber for their livelihoods both for consumed and sold them. Recently, the number of sea cucumber has been decreased due to anthropogenic and environmental degradation. Therefore, the data of bio-ecology of the resources are needed to manage the resources for its sustainability. The objective of the study was to analyze the biodiversity of holothurians. Data were collected by purposive random sampling. The research was carried out from October 2017 to October 2018. The results showed that there were five species of holothurians found during this study. The abundance of holothurians ranged from 18 to 173 individuals which the highest abundance was found in March 2018 whereas the lowest abundance was found in November 2017. The diversity of species differed each month. The study indicated that there were temporal changes in diversity. The diversity index (H’) ranged from 0.733-1.346, meaning low species diversity. The evenness index showed that the abundance of each species had almost similar. So, that there were no predominance species. Nevertheless, three species have a high number or tend to be dominant later namely Bohadschia similis, Holothuria scabra and H. atra.

Published: October 2019

Abstract
Sedimentation is one of the limiting factors for coral life. Suspended and deposited sediment have negative effects on the coral community. The rate of sedimentation can lead to low coral cover, low growth rate and low recruitment. Sediment that enters inner Ambon bay comes from 8 rivers around the bay. In this research, we assess coral reefs condition, calculate the rate of sedimentation, analyze effects of sedimentation on the coral reefs, and observe the change of coral reefs condition in inner Ambon Bay. Distribution and general condition of coral reefs was observed using manta tow method. Three places were then chosen to be surveyed in detail using line intercept transect to determine the percentage of coral cover. Resuspendedsedimet were measured by using sediment traps placed on coral reefs for 3 days. Sea water was collected with Niskin bottle, filtered and analyzed in laboratory to determine suspended particulate matter. The results showed that percentage of coral cover in Hunut, Kate-Kate and Halong are 5.62%, 5.26%, and 8.92% respectively and fall into the category of poor coral reef condition. The percentage of coral cover decreased progressively since 1985. The suspended particulate matter in three locations is more than 20 mg/l and resuspension sediment at Kate-kate is 18.39 mg/cm2/day, Hunut 16.29 mg/cm2/day, and Halong 10.12 mg/cm2/day. The degree of sedimentation in inner Ambon Bay is at the level of moderate to severe.

Abstract
The application of solid boxes to prevent the sinking of small boats had been executed by the authors with small tuna-long boats. This concept was continued to be applied on small passenger speed-boats to find the possibility of application of solid boxes. This is due to some restrictions of spaces inside small passenger boats. The purpose of application of solid boxes on board is to reduce the incoming water and to prevent the boat from sinking. The data of full-scale boats were collected and developed into Maxsurf software. A scale boat model was developed by this software in order to compute and analyze the boat parameters as well as to construct the real boat model. The boat model was arranged for the details of weight components and their centers. The incoming water was filled into the model and tested for its sinkage. The results showed that the boat was sink. Therefore for future work, other method should be considered on the model in order to prevent it from sinking.
