Serious gaming for port development as a learning tool: a case study of port constructor
Authors: Ningrum A D , Van Schuylenburg M 
Published: September 2020

Abstract
Ports play an essential role in nation’s economic growth by fostering trade and development. Making a master plan for port development includes several actions that need to be taken before a final master plan is decided. Implementing such actions in a real situation as a try out for port development will result in time and financial loss, not to mention the effect to the environment and availability of space. Port Constructor is introduced last year as the newest tool to simulate all the planning and development process of a port and see the result of every action in relatively short time. Port Constructor is a serious game, it looks like a game, but it also has a learning objective that needs to be achieved. The primary function of this game is that players can take several actions, undertake tasks, and experience situations which would be impossible to be tried in a real life situation. In addition, Port Constructor allows players to have a position as a port planner and developer, which may not be possible in reality, and experience a real situation within a short period of time. By developing their own port scenario (or real-port scenario) in the Port Constructor, the player will have a real experience as a port planner. This study was conducted to assess the Port Constructor game as a learning tool in port planning and development both for student and more experienced port developers. Furthermore, this study also provides a way of developing scenarios inside the Port Constructor game as well as ensuring that the aim of this game can be achieved by doing a game session together with students and professionals participants. The game sessions were held to prove the playability of the game as a single-player and multi-player game. Resulting in a better outcome when the game played as a multi-player game because players can have a discussion before deciding the next actions that they will take. Examples of several port layouts are provided to prove the flexibility of this game that can be used to accommodate uncertainty of port development when using in the future. In conclusion, developers believe that Port Constructor can be a useful instrument for the learning process of people at the educational level as well as for port developers on their port planning course and project.

Abstract
Semarang city is the capital of Central Java province, which is located on the cost. The Semarang coastal topography is flat, with slope percentage around 0-2%. Most area is almost the same as height as the sea level and in some places are lower. Environmetal problems faced by Semarang related to this topography area tidal inundation, land subsidence and flooding during rainy season. The research was conducted to model locations that area vulnerable to tide inundation. The data of spot height, countour line and the rate of subsidence were analyzed by using Geographic Information System (GIS). The results showed that the Semarang coastal had a high level of vulnerability to inundated area. Tidal flood inundation area was about 2,400 ha with depths varying from 1 to 66 cm. Mitigation of tide inundation impact must be adjusted to land use and social condition of the local community. The house on stilts or lightweight houses that are easy to dismantle pairs is one of the solutions that is suitable for fisherman residential areas. Whereas the trade and service areas must be carried out by raising of the building floor and making protective buildings from sea water.

Abstract
El-Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) climate variability are global climate variability that can affect oceanographic conditions including SST (Sea Surface Temperature). Located between two oceans, the Indian and the Pacific, the variability of SST in Indonesia is influenced by ENSO and IOD. Previous studies have shown that the influence of ENSO in the Java Sea depends on the season, and while positive (negative) IOD decreases (increase) SST in Indonesian seas. This study aims to examine the effect of ENSO and IOD climate variability on the variability of SST in the Java Sea. SST data are obtained from NOAA Pathfinder and Aqua MODIS satellite image data, while wind data is obtained from ECMWF satellite imagery with long observed data for 36 years (1982-2017) using quantitative methods in spatial and temporal, we found that the influence of ENSO and IOD in Java Sea based on the intensity of the anomaly. The intensity of ENSO which is stronger can affect SST more than IOD.

Abstract
Over the past few years, fishery growth has always exceeded economic growth in Indonesia. Based on this performance, more focused policies are needed to manage it. This study aims to develop a strategy for the fishing industry, specifically related to the center of the fisheries processing industry in Indonesia, with a descriptive secondary data approach, including an analysis of the development of fisheries production base areas namely Location Quotient (LQ) and Shift Share Analysis (SSA) during 2013-2018. This study found that LQ scores were high in Maluku Province. The results indicate that related industries have a higher relative advantage than the average of all provinces, or also called basic industries. SSAs with positive scores occur in South Sulawesi Province, which shows that fisheries are a growing industry. Fisheries development strategies from this research include: (1) Improving coordination between sectors, (2) Identification and synchronization of industrial policies; (3) Developing areas that have more than one LQ as a basis for national fisheries; and (4) Selection of suitable industrial scale related to sustainable resources and regional superiority.

Abstract
Since the implementation of AFTA in 2003 and ACFTA in 2004, the fisheries sector is becoming discussed increasingly. AFTA and ACFTA is the door for international trade, especially import and export activities in Indonesia specifically in the fisheries sector. Besides, this sector is one of the labour-intensive sectors that absorbs a significant workforce. To prevent decreasing in export fisheries, competitiveness can be used as an indicator of trade level. This paper analysed the competitive and comparative advantage of Indonesian fisheries products for export destination country such as United States, Japan, ASEAN, China, and the European Union. Data used in this study were retrieved from BPS and World Bank between 2012 to 2017. This paper used several measurement methods to capture comparative advantage measures namely Trade Specialization Index (TSI), Revealed Comparative Advantage (RCA) and Export Product Dynamics (EPD) methods. If fisheries products prove high competitiveness, it can be expected to continue to exist and consistently grow. The results of this study indicate that competitiveness in fisheries sector still increases and encourages domestic production, with the end goal in public welfare. So that in the future, fisheries sector become one of the leading sectors in Indonesia.

Published: September 2020

Abstract
Carp is one of the commercial freshwater fish and requires good preservation to maintain the quality of the meat. The non-thermal food preservation method that is still being developed is by using a high voltage electric shock or often called Pulse Electric Field (PEF). The research on the treatment of electric shock using PEF on carp meat has been done. This study aimed to measure the effect of high voltage electric shock on the quality of the carp fish meat. Fresh carp meat fillets were given exposure to electric shock (30 kV, 60 kV, and 90 kV; frequency 50 Hz; pulse width 0.4 s; 600 pulses) when compared with untreated as a control. The data of log total plate count (TPC) and other quality attributes were analyzed by ANOVA and advanced test with Honesly Significance Different (HSD), while non-parametric data were analyzed using Kruskal-Wallis and Mann-Whitney test. The result showed that in untreated meat fish, the log of TPC is higher than threated meat and significantly different (P < 0.05) at untreated with the treated samples. The electric shock treatment caused temperature increment from 3.3+0.7°C until 5.6+1.3°C but not significantly different between samples. Moisture content decreased significantly due to high voltage electric shock treatment. pH values ranged from 6.46+0.20 to 6.62+0.23 and were not significantly different between treatment. Meat with electric shock treated showed significantly different (P<0.05) on weight loss but not in cooking loss. There are no significant differences in hedonic value except tenderness with 60kV. On the microstructure, the treated meat looks more porous than untreated meat. It is indicating that high voltage electric shock processing was effective in the maintenance of carp meat qualities.

Abstract
The fisheries sector’s potential is quite large in Indonesia, and during the administration of President Joko Widodo, the demand for fisheries experienced a positive growth trend, which increased 48 percent from 2014 to 2018, from 6,400 thousand tons in 2014 to 9,480 thousand tons in 2018. On the demand side, in addition to domestic demand, the demand for fisheries exports has also increased. Even though there is great potential in output, the absorption of fisheries sector loans is very low, which is only 0.20 percent on average along 2014-2018, and the Non-Performing Loans (NPL) of bank loans in the fisheries sector are quite high. From the data of April 2019, the NPL of the fisheries sector was 6.9 percent of the total loans in the sector. This study aims to analyze the factors that affect the NPL in the fisheries sector in Indonesia by using the error correction model (ECM) on the 2010-2019 monthly data, for long and short-term of variables relationship. The empirical model developed to analyze the NPL value of the fisheries are affected by the interest rates, inflation, and output growth of the fisheries sector. This study finds that in the long run NPL is negatively affected by output growth of fisheries sector, and positively affected by inflation and the interest rate of fisheries sector. The cointegration test supports the long-term relationship of the dependent and independent variables of the model. The results of the short run model analysis indicate the suitability of the sign with the hypothesis and in line with the results on the long-term model. The results of the long and short-term analysis can be a policy consideration for financial authorities regarding the projection of NPL in the future.

Abstract
Low carbon development has become a trendsetter in this millennial era. The social and economic factors of the community are commonly used variables in assessing linear functions of the level of social welfare. The level of social welfare is then thought to be one of the main drivers of anthropogenic pressure on the environment. We examine the extent to which social and economic aspects of capture fisheries activities influence the dynamics of CO2 emissions generated from capture fisheries activities in all coastal areas in West Java Province during the 2007-2016 period. Based on the results of geographic information system and statistical analysis, we find that the increasing economic factor can reduce the ghg emission while the increasing of social factor on the contrary can increase the ghg emission. The GIS analysis also show that the level of CO2 emissions was found to be lower in districts that had relatively high levels of social index. It is estimated, the higher level of education and social welfare has a real positive correlation with increasing public awareness in conducting fishing activities that are environmentally friendly and carbon friendly.

Published: September 2020

Abstract
The objectives of the study were to evaluate the effects of exogeneous papain enzyme supplemented feed on the growth and blood profiles of Sangkuriang catfish (Clarias sp). The intensive culture system of Sangkuriang catfish decreases water quality that hinders fish growth. The cultivation practices also develop diseases that further decreases the production, including through feeding that contain immunostimulant. The fish sample was Sangkuriang catfish with the average weight of 12.84 (±0.69) g per fish. The experiment used papain enzyme supplemented feed with 5 (five) treatments. Those treatments were A (0 g papain per kg feed), B (0.5 g papain per kg feed), C (1 g papain per kg feed), D (1.5 g papain per kg feed), E (2 g papain per kg feed). Parameters observed were diet usage efficiency (EFU), ratio of protein efficiency (PER), relative growth rate (RGR), survival rate (SR), blood profiles and water quality. The results show that papain enzyme supplementation in the feed significantly (P<0.01) affected on EFU, PER, and RGR; however, it did not significantly influence SR and blood profiles of Sangkuriang catfish. The optimal dose of the papain enzyme for EFU, PER and RGR were 1 g per kg feed. The water quality during study had been in feasible condition for Sangkuriang catfish cultivation.
