Abstract
Two 6 t beam dumps, made of a graphite core encapsulated in
a stainless steel vessel, are used to absorb the energy of the two
Large Hadron Collider (LHC) intense proton beams during operation of
the accelerator. Operational issues started to appear in 2015 during
LHC Run 2 (2014–2018) as a consequence of the progressive increase
of the LHC beam kinetic energy, necessitating technical
interventions in the highly radioactive areas around the
dumps. Nitrogen gas leaks appeared after highly energetic beam
impacts and instrumentation measurements indicated an initially
unforeseen movement of the dumps. A computer modelling analysis
campaign was launched to understand the origin of these issues,
including both Monte Carlo simulations to model the proton beam
interaction as well as advanced thermo-mechanical analyses. The main
ﬁndings were that the amount of instantaneous energy deposited in
the dump vessel leads to a strong dynamic response of the whole dump
and high accelerations (above 200 g). Based on these ﬁndings, an
upgraded design, including a new support system and beam windows,
was implemented to ensure the dumps' compatibility with the more
intense beams foreseen during LHC Run 3 (2022–2025) of 539 MJ per
beam. In this paper an integral overview of the operational
behaviour of the dumps and the upgraded configurations are
discussed.

AbstractIn aquaculture, fish larvae regularly need a balanced diet according to the timescale because such diets essential for constant growth and reproduction and can avoid malnutrition. Thus, the use of live food organisms is critical as it will first feed for fish larvae. Studies have shown that zooplankton have more excellent digestibility and are suitable as live prey species for different sizes than other live foods (e.g. rotifer and Artemia). However, zooplankton nutrition still needs to improve to meet the nutritional requirement for fish larvae. Feeding zooplankton with well-nourished microalgae is important as it affects the nutritional value of the zooplankton. Algal growth is related to micronutrients (e.g. nitrogen, phosphorus or selenium) supply in the culture medium and the availability of nutrients affects the quality of the algal. Thus, by enriching the algal diet with micronutrients from the culture media, the nutritional value of zooplankton can be improved. This review focuses on the nutritional value of zooplankton through the manipulation of algal media composition as well as wastewater. The relation between the composition of algal media and nitrogen and phosphorus limitation are also discussed. The review links the microalgae nutrient essential with manipulating algal media composition and the change of zooplankton nutrients.

AbstractCopepods with a wide range of sizes, species, and nutritional compositions are preferred as live food for rearing of Betta splendens larvae. This research focuses on evaluating the efficiency of copepod enrichment diets in improving the coloration and feeding rate of B. splendens. Copepod were enriched withChlorellasp. (T1), capsicum (T2), mixed vegetable (carrot + spinach), (T3), yeast (T4) and rice bran (T5) in 24 hours prior the feeding tests. As a result, proximate analysis of enriched-copepods showed that T1 (70.88±0.41) has highest protein content and T5 (22.01±0.59) has the highest lipid content. The specific growth rate and survival rate of B. splendens was highest in the treatment T1 (2.56±0.07%; 91.11±1.92%) and followed closely by T3 (2.49±0.51%; 85.55±8.39%). Feeding rate, T3 (70.08±3.88%) presented highest rate compared to other treatments. The different enrichment diets used were significantly impact the coloration test on body of L* value (P=0.001, P<0.05), T3 (66.11±3.60) appeared darker in color in contrast to others. As for a* value, the coloration was not impacted with the use of different enrichment on copepods (P=0.158, P>0.05) was detected for T1 (2.84±0.73) that gave a redder shade than other treatments did. T3 (2.40±0.30) exerted a more yellowish shade than the rest for b* value with a significant difference (P=0.015, P<0.05). The current study demonstrates that, rice bran, capsicum and mixed vegetable enrichment (carrot and spinach) have the potential to be an effective means of increasing B. splendens coloring and feeding rate. This potential diet can be further used as a substitution to artificial foods in producing sustainable culture of ornamental fish in the aquaculture industry.

Abstract
Coastal management is an important issue for most regions of the world. This is because the initial activities in the fisheries and marine sector began in this area, ranging from capture fisheries, aquaculture, processing of fishery products to marketing. But in reality the management of coastal areas is not optimal and evenly distributed, even though fishery and marine resources have high economic and ecological value, as happened in the coastal area of Torokeku Village. This study aims to determine the appropriate community development approach strategy through the eco blue sea concept in order to maintain fisheries and marine resources found in the coastal area of the Bajo tribal community in Torokeku Village, South Konawe Regency. The research was conducted using descriptive qualitative analysis method. Collecting data through direct survey techniques in the field. The results obtained show that community-based coastal area management by seeking the development of coastal communities can be carried out through structural and non-structural approaches, so that in order to maintain these resources, their management must be carried out in a planned and integrated manner and able to provide the greatest benefit to all stakeholders, especially coastal communities, and minimize impacts and conflicts that may potentially occur.

Published: November 2021

Abstract
Boiled salted fish is one of the favorite fish processing commodities in Bogor. Every year its production increase in line with potential health hazards for consumers, one of which is caused by contamination of raw materials by microplastics. The socio-economic of people were suspected of having influenced the occurrence of the contamination. The study area took place in Bogor, aiming to analyze the correlation between socio-economic and microplastic contamination in boiled salted fish. The purposive sampling method was used in this study on 150 consumers representing gender, age, education, occupation, and income. The result was analyzed with descriptive and inferential statistics using the likelihood ratio, wald, and odds ratio test to determine which variables had the most influence. The analytical results showed that the variables of gender and education had a significant correlation (95%) with 0.5-7 times of risk. It is shown in the wald result, and the odds ratio is 2.619-17.182 (more than x2
(df,a) value) and 0.453-7.044. It can be concluded that the potential of microplastic contamination in boiled salted fish correlated with gender and level of education and can be controlled by enhancing the understanding of gender groups through improving public education to a higher level.

Abstract
Poso in Sulawesi, primarily the Lake Poso and Poso River, is known as eel (Anguilla spp.) fishing areas. Therefore, research of eel fishing is required as base information for evaluating and determining policies for its activities. The eel fishing research in the Poso area was conducted through primary data observations, secondary data traces, and interviews from April to June 2021. The fishing activities take place in the Lake Poso and Poso River shore and the rivers of the lake inlets. The fishing gear that contributed greatly to the catch was fence traps and spears. The local community’s fence trap called waya is a unique gear only found in this area, and it is installed in Poso River around the lake outlets. The gears block the rivers to catch downstream migration eels. The spear is fishing gear (including for eels) operated at night in shallow waters, especially in the outlets of Lake Poso. The eel production recorded from the Poso areas for the last four years has been 6.7–15.5 tons per year, and the highest production was in Pamona Puselemba.

Abstract
Banda Aceh is a city at the western tip of Indonesia and is one of the provinces that has a coastal area that can contribute plastic waste to the sea. The source of plastic waste comes from land and human activities which are then carried through river mouths to end up in the sea. The purpose of this study was to determine the characteristics of marine debris at the mouth of the Krueng Aceh River. Data collection is determined based on the time of the tide. The research was carried out using a boat mounted with a marine debris trap. The results showed that plastic waste dominated the mouth of the river by 90 percent, both during high and low tide conditions. There is a difference in the amount of waste that accumulates at high and low tide in the Krueng Aceh estuary.

AbstractLaut Tawar Lake is located in the town of Takengon, Central Aceh district. Currently, Laut Tawar Lake has been utilized by the surrounding community as a fishing spot. One of the fishing gears used by fishermen isBubu wau. One of the catches obtained by fishermen is crayfish. The crayfish has a high economic value, so the lack of control over the intensity of the catch also causes the average size of the crayfish caught, because catching crayfish is a transition from catchingRasbora tawarensis. One of the problems that frequently occur and research on crayfish has never been done before. Therefore, this research needs to be done. The purpose of this study was to determine fishing catch compositions ofBubu wauand the size distribution of crayfish carapace length ofBubu Waufishermen in the Teluk One-one, Laut Tawar Lake. The research was carried out in about March 2021. The description of the fishing catch composition was analyzed by using the describded method. The size distribution of crayfish carapace length was analyzed by the Sturgess rule. From the results of the study, it can be concluded that the catch compositions ofBubu wauin Teluk One-one are crayfish, suckermouth catfish, channeled apple snail and tilapia. The type of crayfish caught by fishermen’sBubu wauwasCherax quadricarinatusamount of 4232 individuals (89% of the total catch), where the total length of the dominant crayfish carapace was 4.4-4.9 cm with a total number of 1403 and the least with a size of 8.6-9.1 cm was 1 crayfish from the total catch

Abstract
With the increased scale of marine aquaculture in the Beibu Gulf, as well as accelerating urbanization and industrialization, frequent harmful algal blooms (HABs) have occurred in this area, especially those formed by Phaeocystis globosa in the past several years. As the P. globosa bloom has been a serious marine ecological disaster in the Beibu Gulf, research on quick and effective methods to eliminate P. globosa blooms is a hot research topic. In this study, the bacteria Streptomyces yatensis B4503 combined with modified diatomite was used to prepare algicidal modified clay, which was then used to study the removal effect on P. globosa blooms in field culture enclosures. The results showed that after 6 h of treatment with algicidal modified clay, compared with the blank control group, the cell density and chlorophyll a content of P. globosa decreased by 26.86% and 64.03%, respectively, and they decreased by 75.23% and 84.81%, respectively, after 24 h. The study indicated that algicidal modified clay can be applied to eliminate HABs caused by P. globosa in coastal water.

AbstractThis study aimed to examine the effect of Gamal leaves flour supplementation in commercial feed on the growth of Nirwana tilapia (Oreochromis niloticus) fingerlings. The experimental design used was a non-factorial completely randomized design consisting of four treatments and four replications. The treatments studied included commercial feed without supplementation of Gamal leaves flour as a control (P0), commercial feed with supplementation of Gamal leaves flour 10% kg−1feed (P1), commercial feed with supplementation of Gamal leaves flour 15% kg−1feed (P2), and commercial feed with supplementation of Gamal leaves flour 20% kg−1feed (P3). Nirwana tilapia fingerlings were stocked at a density of 1 fish L−1. Nirwana tilapia fingerlings size ranges from 2-3 cm. Nirwana tilapia fingerlings maintenance period lasts for 40 days. The Annova test showed that the treatment gave a significant effect on the weight gain, length gain, daily growth rate, and feed conversion ratio (P < 0,05), but did not give a significant effect on the survival rate of Nirwana tilapia fingerlings (P > 0,05). The best dose to increase the growth of Nirwana tilapia fingerlings was commercial feed with supplementation of Gamal leaves flour 10% kg−1feed.
