Abstract
The gender perspective in community forest management in Central Lombok Regency is focused on analyzing gender equality in domestic and productive activities, particularly access and control of forest resources. This research is conducted by using Framework Harvard Analysis through interviews with respondents, in-depth interviews and focus group discussions with certain informants. The unit of this research’s analysis is women whose household has the right to manage community forest. This study shows that there is a gender equality bias which is indicated by the low participation of women in controlling forest resources (planning, regulation, evaluation) due to the stereotypical view of gender roles in decision making which is dominated by men. However, the high participation of women is more involved in terms of access to forest resources (implementation, crop productivity, utilization) to improve household food security. Forest farmer households with a high level of gender equality through the active involvement of women in controlling forest resources will improve social and economic adaptation strategies with a high level of diversity.

Abstract
The pattern of food consumption determines the level of household welfare, but for households with low income, the share of food expenditure is dominated by carbohydrate food. Protein foods are the second food consumed after carbohydrate staple foods. This study analyzes food consumption patterns away from home as a source of protein for households in Indonesia. The research data uses secondary data in the form of Susenas data in 2020 which covers of thirty-four provinces and the samples cover 334,127 households in total. The research data is in the form of total household expenditure data, data on the number of household members, consumption and expenditure data of FAFH as a source of household protein in Indonesia covering eight types of food, namely 1) soup namely soto, gule, sop, rawon 2) satay, tongseng 3) meatball noodles, chicken noodles 4) cooked fish 5) cooked chicken or meat 6) processed meat 7) chicken porridge, and 8) dumplings, batagor. The consumption preference model approach uses the Probit Model. The results showed that all FAFH foods had a high significant effect on FAFH consumption patterns. However, the household size variable shows a negative relationship. The higher the household size, the lower the possibility of consuming FAFH. The findings of this study demonstrate that, despite the COVID-19 pandemic, the intake of FAFH protein is increasing, albeit at a very slow rate. This also demonstrates that FAFH food is a source of protein for households in Indonesia.

Abstract
Arafura Sea is well-known as the important area for commercial shrimp fisheries in Indonesia. The density of shrimps was highly influenced by their fishing pressure and environmental condition. The objective of this research was to study the distribution of shrimps based on its stock density and their relationship with the environmental variables. Trawling swept area method was used in 16 sampling sites of Arafura Sea during the transition monsoon in 2016. Some environmental variables in bottom layers as shrimp habitat were measured, including chlorophyll-a, dissolved oxygen, depth, salinity, temperature and pH. The results showed that the largest density of shrimps was found in the southern coast of Aru where it has the largest concentration of chlorophyll-a and dissolved oxygen. Among all the environmental variables, Chlorophyll-a was the main variable affected the density of shrimps. Three most dominant species were Penaeus semisulcatus, Metapenaeus endeavouri and Metapenaeus ensis. There was indication of the decreasing shrimp stock in Arafura Sea. The ecosystem-based fisheries management should be developed to rebuild the stock density and to enhance the environmental quality of Arafura Sea.

Abstract
Coral reef degradation in Indonesia is increasingly alarming. For this reason, efforts are needed to rehabilitate coral reef ecosystems. In this study, we explained the effect of coral transplantation on the structure of coral fish communities in the waters of Harapan Island, precisely on Rosa and Pamegaran Island, Seribu Archipelago National Park. The study of the reef fish community structure was carried out for 8 weeks from February 2019 to April 2019. This study was conducted by scuba diving to dive directly into the coral transplant sites. During the study period, a total of 35 species (14 families) were observed. There is an increase in fish abundance per 50m² which is significant over time for 8 weeks of observation (α 0.05). Significant differences in abundance of reef fish also occurred between the two islands (α 0.05), indicating that differences in the depth of the location of coral transplants can also affect the abundance of reef fish. It can be concluded that coral transplantation efforts succeeded in increasing the abundance of individual reef fish on both coral transplantation islands.

AbstractMangrove forest habitats of great variety can be found in the Karimunjawa Islands, which is located in Indonesia. The Karimunjawa Islands, located in Jepara Regency, is a group of 27 islands in the Java Sea. Mangrove is a type of vegetation that protects coastal habitat. The ecosystem’s long-term sustainability will be determined by its regeneration condition. This study aimed to examine mangrove community structure and mangrove regeneration at Karimunjawa. The study area was determined by purposive sampling technique with plot at size of 10 x 10m for tree, 5 x 5m for sapling, and 1 x 1m for seedling. This study revealed 11 mangrove species with the highest IVI value of 63.60% forR. stylosaat Kemujan Island, andL. racemosawith an IVI value of 109.71% at Jati Kerep Aquaculture Area. The diversity index (H’) was ranging between 1.55 to 2.00 and both study areas shared high similarity (SI = 70.59%). It was revealed that mangrove species grow at a slightly slower pace in Karimunjawa, as indicated by the number of individual number of seedlings (179 ind/ha) < sapling (234 ind/ha) < tree (239 ind/ha). Further test using one-way analysis of variance (ANOVA) revealed that there was a non-statistically significant difference in mean between Kemujan Island and Jati Kerep Aquaculture Area (F(1,4) = [3.136], p = 0.151).

Abstract
Fishbone (FB) is a nutritionally dense by-product of fisheries processing, which is a good source of Ca and other elements. This study aimed to determine the effect of sonication and water bath treatments on the size and nutritional value of Pangasius bone powder. Pulverized FB was soaked in 40% lime solution (pH 2) under different conditions in a sonicator and water bath for 30 min. and 60 min. at 60 C, and then powdered. The whiteness index (WI), pH, particle and distribution size, proximate and mineral contents of FB powder were investigated. This study showed that sonication treatments were 89.09-89.17 for WI, 6.99-7.14 for pH, 860.15-1029.3 nm for particle size, 3.66-3.95 % for fat, 14.62-16.10 % for protein, 50.48-50.91% for Ca, 14.77-15.08 % for P and water bath treatments were 88.91-88.93 for WI, 7.36-7.43 for pH, 734.5-959 nm for particle size, 3.22-3325 % for fat, 14.78-15.23 % for protein, 50.97-50.95 % for Ca, and 14.97-14.99 % for P. Both showed a mono-modal size distribution and trace amounts of other minerals in all treatments. In conclusion, a 60-minute water bath treatment is a promising method for reducing the particle size of FB powder without significantly altering its nutritional composition.

Abstract
Bacterial disease control in shrimp ponds was currently taking a more environmentally friendly approach. Thwas study aims to find out the effectiveness of Porphyridium aerugineum as a controller of Vibrioswas in ponds. This research was carried out at with two treatments with three replications. The first treatment was the administration of whole-cell microalgae P. aerugineum and the second treatment was control without microalgae administration. Tiger shrimp was stocked at the stadia PL 12 (density of 8 shrimp fry/m2). The study used 6 ponds measuring 10m x 25m with a water depth of 80cm. Microalgae was given once a week. A sampling of pond water and sediment was carried out once in two weeks. The results showed that the addition of wholecell microalgae P.aerugineum in ponds can reduce the ratio of total Vibrio bacteria and total plate count in ponds water but not in pond sediments. In ponds fed microalgae P.aerugineum, shrimp survival rate and production were higher than those of in controls. The results of thwas study showed that the adminwastration of microalgae as an additional supplement in ponds gave better results compared to the control.

Abstract
The experiment was aimed to describe the growth performance of the second generation (G2) of domesticated blue swimmer crab, Portunus pelagicus. The crablet stage was cultivated in three different outdoor rearing conditions: a) each crablet was placed individually in 250 ml-plastic (plastic-cup), b) crablets were reared in an 8 m2 concrete tank with shelters (concrete), and c) crablet reared in the 90-t concrete tank with sandy bottom (sandy-bottom). The crab was fed a commercial prawn diet, and the growth and survival rate (SR) were recorded. The result showed that the final weight (W) and carapace width (CW) in all treatments were significantly different (P>0.05), where the highest in sandy-bottom followed by concrete and plastic-cup. However, there was no significant difference (P>0.05) in the W and CW between the female and male crabs from concrete and plastic-cup systems. Still, males grew significantly higher than females (P<0.05) in sandy-bottom. Meanwhile, the SR varied between rearing conditions. The highest SR was recorded in plastic-cup (97%), in contrast to 52% and 32% for concrete and sandy-bottom, respectively. In addition, a part of the female crab from the sandy-bottom population could have reached the mature stage at the end of the experiment.

Abstract
Marine debris one of the source of marine pollution that will damage marine ecosystems and be harmful to human health. To deal with marine debris, the government has formed a national action plan for marine debris 2018-2025 as the implementation of Presidential Regulation No. 83 of 2018 concerning the handling of marine debris. Law enforcement is one of the strategies in the action plan, but in practice, law enforcement cannot implemented effectively. The absence of sanctions given to the garbage throwers and the absence of socialization of the rules regarding marine debris make there no deterrent effect and therefore increase the amount of marine debris in Indonesia. This study uses a normative juridical approach with analytical descriptive research to describe and analyze the use of international legal instruments nationally. The results of this study are that strict rules must be made, especially the imposition of sanctions on the perpetrators of marine waste disposal so that it will have a deterrent effect, sanctions can be in the form of fines or criminal sanctions. The government also must socialize to the public regarding the provision of these sanctions, so that there is good cooperation between government and community.

Abstract
Nilem carp, Osteochilus hasselti is one of the local species which has an economic value in Indonesia especially the fingerling size “baby fish”. The purpose of this research is to determine the suitable of aeration rate for feeding incidence, survival, and growth. The aeration rates of this research were adjusted to A) 0 ml/minute; B) 500 ml/minute; C) 1,000 ml/minute; D) 1,500 ml/minute; and E) 2,000 ml/minute. Each treatment consisted of three replicates. 600 of newly hatched larvae (1 day old) were stocked in the fiber tank with size of 60 x 40 x 40 cm. Each fiber tank was completed by water heater. Larvae were cultured for 45 days. Larvae were fed Artemia and artificial diet. The parameters observed such as feeding incidence, survival, absolute weight and absolute length. The result showed that the aeration rate has influenced feeding incidence, the survival, absolute weight, and absolute length (P<0.05). The water quality parameter such as dissolved oxygen was affected by aeration rate where the higher of aeration will be led to increase the value of dissolved oxygen concentration. The aeration rate of 1,000 ml/minute is recommended to be suitable for larviculture of nilem carp in order to increase the seed production.

Abstract
Tsunami-prone areas on the western and southern coasts of Sumatra, Java, and Bali are home to more than a hundred million Indonesians. As preliminary research, the main goals of this paper are to present a hazard assessment methodology that identifies areas of high tsunami hazard and the spatial distribution pattern of inundated areas and its energy transfer to the inland with various relief (land) in coastal cities. The methods established here are based on a geographic information system (GIS) approach by combining the numerical modelling, wave height, and remote sensing data. We also examined the variations of spatial hazard distribution with a medium spatial resolution (30 m) among the pilot sites studies. The result stated that medium spatial resolution has limitations to model the inland tsunami inundation and its energy in the plain area. Still, it can model in the dynamic elevation variation. Under the 10 m wave height scenario, the highest mean of inundation depth among four pilot sites is in Kuta (5.9 m with an energy wave (Ewave) of 38.34 MJ), followed by Banyuwangi (5.5 m with Ewave of 33.32 MJ), Pacitan (5m with the Ewave of 27.53 MJ) and Sibolga (3.9 m with the Ewave of 16.75 MJ), respectively.

Abstract
The measured of 210Po concentration in the commercially fish muscle has been conducted in fish species collected in southern coast of Sukabumi in 2021. 210Po is a natural occurring radionuclide from the 238U series in the environment and become a concern due to radiotoxic effect for the health of consumers. This study aims to determine the concentration activity of 210Po and to evaluate the annual effective dose of 210Po on fishery products in southern coast Sukabumi. There were ten different species of marine fish were analyzed using an alpha spectrometer. The results showed that the highest concentration of 210Po activity was in a common dolphinfish at 13.57 ± 2.03 Bq Kg−1 dry weight. This activity value was exceeded tolerable limits as reported by the global recommended concentration of 210Po for fish was about 2.4 Bq Kg−1. The lowest concentration of 210Po was found in Pink ear emperor fish at 0.18 ± 0.10 Bq Kg−1 of dry weight, which below minimum threshold of limit concentration activity. The results of the investigation that the average effective dose from one year fish consumption in Sukabumi for adult consumers ranged from 1.05-112 (µSv/a), children (10 years) ranged from 2.27 – 243 (µSv/a), and infant consumers (1 year) ranged from 7.67 – 821 (µSv/a). The annual dose from 210Po intake in the recent study are lower from reference level of 1 mSv, therefore 210Po was not become a concern.

Abstract
Tempe, Sidenreng and Lapompakka lakes have potential fisheries. One species mostly consumed is Tawes, Barbonymus gonionotus. Household waste, and industrial and agricultural activities around the lake are suspected to be the source of metal pollution to these lakes and their organism, particularly of lead (Pb) and cadmium (Cd). This study aim to analyze the lead (Pb) and cadmium (Cd) concentration in Tawes, Barbonymus gonionotus and to determine whether this Tawes species is still safe to be consumed. Total samples collected were 54 fish. The Pb and Cd concentration was determined from the fish flesh and analyzed using the Atomic Absorption Spectrophotometry (AAS) method and presented descriptively. The results showed that the concentrations of Pb and Cd in this species of all three lakes were not detected. Based on the quality standards for metal contamination of Pb and Cd in the fish and its processed products according to SNI (2011), the concentrations of Pb and Cd in the three lakes have not exceeded the standard, meaning that Tawes fish is still suitable for consumption.

Abstract
Ledulu Lake is one of the lakes in the Rote Ndao Region. Lake Ledulu was formed in the Quaternary period with Cenozoic constituents and Neogene deposits based on geological formations. The formations found in the Lake area are sediment, chemical, limestone. The purpose of this study was to measure the metal content in the lake water and its absorption by aquatic vegetation in the ecosystem of Ledulu lake, using Instrumental neutron activation analysis (INAA) technique. NAA is one of the modern methods that is able to measure the level of heavy metal uptake in aquatic biota (water animals and aquatic plants). The metal content in the water of the lake (mg/L) is: Bromine 405.06, Calcium 7,195.66, Cerium 9.10, Cobalt 2.43, Chromium 45.90, Lanthanum 12.07, Magnesium 1,189.93, Sodium 24,382.31. Aquatic plants that absorb heavy metals in lake Ledulu are Panicum sp, Ludwigia adscendens (L.) H.Hara, Ottelia alismoides (L) pers, Najas sp, Ipomea aquatica Forssk, Pontederia korsakowii (Regel & Maack) M.Pell. & C.N.Horn, Callitriche sp, Bacopa monnierii, and Nymphaea alba L. Sodium is not absorbed by Panicum sp, Ludwigia adsendence (L), and Nymphaea alba. Lanthanum is only absorbed by Panicum sp and Callitriche sp. All other elements can be absorbed by aquatic plants in the Ledulu lake ecosystem with different absorption concentrations.
