Abstract
Ratoon rice farming is the method of harvesting rice for 2-3 times by maintaining and growing the shoots from the previous tillers. In Central Java, Indonesia, ratoon rice is local wisdom in farming called Singgang. Nowadays, almost no farmers are implementing ratoon rice farming, in spite of many advantages for climate change adaptation and mitigation. The objectives of this research are to identify and to map out the current implementation of ratoon rice farming in Central Java; and to formulate the strategies to develop the ratoon rice farming as local wisdom in Central Java. This research was conducted from November 2019 to January 2020, using qualitative research with the FGD method. The research location was chosen by purposive sampling according to three irrigation systems, namely: rainfed rice field in Gondangrejo, Karanganyar Regency; Tidal rice field in Tuntang, Semarang Regency; and technical irrigation rice field in Kebonagung, Demak Regency. The data obtained were analyzed using the SWOT (Strength, Weakness, Opportunities and Threats technique). The results showed that the highest potential to develop ratoon rice farming in Central Java is on rainfed land. Development of ratoon rice for climate change adaptation and mitigation is influenced by the characteristics of farmers, environmental conditions, irrigation systems, the activity of extension workers and farmer groups, the motivation of farmers to innovate. Therefore, the strategies suggested to develop the system are: to increase the role of extension workers and farmer groups, as well as agricultural production facilities, so that the motivation to maintain the local wisdom and accept technological innovations raise; and to minimize the decline in ratoon rice production by intensive farming management and specifically create ratoon rice farming area.

Abstract
Nutmeg tree (Myristica fragrans) is Indonesian native tree species originating from Maluku Island, especially Ambon and Banda. The spread of nutmeg in Bogor area can be traced back to the Dutch colonial period when different kinds of spices were traded across the Indonesian archipelago and beyond. Having this long history, nutmeg is now widely used in Bogor’s culinary. At the national level, it has high economic value and become one of Indonesia’s main export products. However, there is little research on nutmeg tree spatial distribution. The objectives of the study were : (1) identify the nutmeg trees spatial distribution in Bogor city (2) mapping the existence and identification of nutmeg trees conditions and growing environment. This research was conducted Bogor City from February - May 2018. The data was obtained through direct interview, study field, and study literature. Data collection is determined based on the distribution of nutmeg trees in Bogor City, and extinct status based on study literature. Furtehermore, the existence of nutmeg trees in Bogor collected used purposive and snowball technique. The results showed that a total of 108 nutmeg trees were found in all sub-districts of Bogor city. These trees grow in a variety of areas such as green corridor, public park, agriculture farm, riverbanks, yard, office park, and cemetery. The results of this study can be used as the basis for determining the preservation strategy and area for nutmeg conservation in Bogor city.

Published: September 2020

Abstract
The flooding risk has always been considered as an important factor ofthe risk safety management of dams. The extreme flooding in the downstream of a dam could be either due to dam failure or sometimes without failure. In both cases, they give serious risks to people and property in the downstream of the dam.Sukamahi dry dam at Cisukabirus River is a part of the upper Ciliwung Watershed, located in Bogor regency. Sukamahi dry dam was design for flood reduction purpose especially for the downstream regione.g. Bogor City, Bogor Regency, Depok City and Jakarta. Sukamahi dam has a capacity in flood reduction of 13.53 m3/s with probability exceeded 2 %, and time to concentration (tc) of peak discharge (Qp) at least 4 hours longer than the existing condition. Construction of dry dam might increase the magnitude of flood prone risk especially on the dam breach caused by spillway capacity failure case, although with lower probability. Simulation using HEC RAS 4.1 and an ex-antehydrological risk valuation Xrisk model wereperformed with three scenarios, i.e. normal risk, risk averse and risk takers, with simplified option value and option risk calculation. Risk valuation can be used by decision makers to evaluate the technical and risk feasibility of Sukamahi dry dam construction.

AbstractOrange-dotted tuskfishChoerodon anchoragowas a Labridae family that could be found in coral reef and seagrass ecosystems. Orange-dotted tuskfish has a wide distribution in Indo-Pacific waters which has an important economic value that needs to be managed sustainably. This study aims to analyze the sex-ratio and maturity of orange-dotted tuskfish. The samples were collected from fishermen catches that were landed at the Rajawali Makassar Fishing Port at Makassar city. The orange-dotted tuskfish sex ratio was not balanced between males and female. Macroscopically, it was seen that orange-dotted tuskfish was a hermaphrodite. The synchronicity of maturity stages between male and female, both based on the sampling period, and the length class indicated that the process of reproduction, especially fertilization, was relatively safe. Female orange-dotted tuskfish that reach the first maturity earlier than male; suggest that orange-dotted tuskfish was most likely a protogyny.

Published: September 2020

Abstract
There is a difference in growth between male and female mud crabs, where males grow faster than females. However, the price of female crabs can be higher than males when female crabs contain eggs which can reach one-third of the whole meat portion. Therefore, the preference for monosex or multi sex cultivation in aquaculture can provide different earnings. Sex reversal has been successfully carried out on various aquaculture fish species, but is yet not common in crustaceans, especially in mud crabs. This preliminary experiment aims to determine the possibility of the masculinization of mud crabs treated with 17α-Methyl Testosterone (MT). The experiments were carried out by the immersion of four-day-old crablets (C-4) with various doses of MT hormones (0, 1, 10, and 100 ppm) for four hours. Following the immersion treatment, crablets reared individually for two months before the male percentage was calculated at the end of the experiments. The result of the experiment showed that immersion with MT hormone solution at a dose of 100 ppm for four hours resulted in total death, whereas no deaths occurred at 0 and 1 ppm. While at 10 ppm treatment, 10% mortality occurred. The MT hormone immersion was found to be ineffective in sex inversion of the C-4 mud crabs where the male sex percentage between treated crab and the control was not significantly different (P>0.05). On the other hand; the second study showed that immersion of C-4 krablet with a dose of 7.5 ppm followed by feeding with MT containing diet for 30 days at 2.5-7.5 mg kg1 feed resulted in 100% male.

Abstract
Seaweed cultures in marine coastal waters provide providing microhabitats, shelter, and food sources to fish and invertebrate. The availability of blue swimming crab (Portunus pelagicus) in seaweed culture area was conducted from October to December 2019 in the south coastal waters of Bulukumba Regency, South Sulawesi, Indonesia. The purpose of the study was to assess the catch, size, and sex distribution of the blue swimming crab in the area. The crabs were caught by set bottom gillnets with 4 inches of mesh sizes and 300 m of a length. The carapace width (CW) and sex for each crab individual were recorded. The results of the study show that the total catch of 21 trips during 3-month fishing operation was 539 crabs that consist of 260 male (48.24 %) and 279 females (51.76 %). The (CW) of males ranged from 53.6 to 143.6 mm, while females ranged from 58.3 to 142.8 mm. There were 38 breeding crabs or 13.62 % from the female total. The carapace width of breeding crab ranged from 92.2 to 138.6 mm. Moreover, it needed to study in the area intensively.

AbstractThe focus of this research is the effect of intensive and traditional ponds on the organoleptic quality of white shrimp (Penaeus vannamei) during 8 days of storage. The study was conducted in a traditional pond at Manjalling Village, Ujung Loe Sub-District, and intensive ponds at Mariorennu Village, Gantarang Sub-District, Bulukumba District. The study design was carried out using the Randomized Block Design experimental method, with storage treatment of 0,2,4,6,8 days. The parameters studied were appearance, odor and texture. White shrimp from intensive ponds and traditional ponds are put in a cooler with a ratio of 2:1 ice and shrimp. The addition of ice is done every day and organoleptic testing is done at 2-day intervals. Around 10-20 g samples were used for organoleptic test using methods employed in SNI 01-2728.1-2006. Data analyzed using Kruskal Wallis continued with multiple comparisons. Organoleptic test of intensive and traditional ponds in 8 days storage shows the value of organoleptic quality decreases and is not acceptable for consumption, with shrimp appearance values 6.28 and 6.64; the odor of 6.15 and 6.59 and textures of 6.24 and 6.6. The standard organoleptic value is 7 based on SNI method. Therefore, shrimp is rejected because it does not meet the minimum specified quality. The conclusion is the organoleptic quality value of traditional shrimp ponds is higher than intensive shrimp ponds.
Characterization chemical composition of skin and head bones barracuda (Sphyraena jello) as collagen raw material
Authors: Harianti  
Published: September 2020

Abstract
Barracuda is one type of fish that is widely used in the diversification of processing fishery products. This business will increase the amount of waste if it is not managed optimally. This study aims to utilize fish skin and head bones as raw material for collagen, which can reduce the amount of fish processing waste and provide added value to the waste. Barracuda skin and head bones that will be used as a raw material in the manufacture of collagen are first characterized by analysis of the chemical composition of the skin, which includes water, ash, protein, fat content. This chemical composition analysis aims to assess the initial feasibility of barracuda skin and head bones as raw material for collagen. The results of proximate analysis of the skin and head bones of barracuda (Sphyraena jello) showed a water content of 67.39%; 22.56%, ash content 2.53%; 58.45%, protein content 21.69%; 14.32%, and fat content of 8.38%; 4.58%. Barracuda skin and head bones are still fresh in terms of the value of water content that is still in the range of water content of the skin and head bones in general. High protein levels in the skin compared to head bones barracuda allows it to be used as raw material for collagen. Barracuda skin and bone fat levels are high enough, so pretreatment needs to do to remove fat and minerals so that it can improve the quality of collagen produced.

Published: September 2020

AbstractThe way to prevent or treating bacterial diseases outbreaks with drugs or chemicals is the one of main solutions to solve the problems in aquaculture. The use of antibacterial agents has increased significantly in aquaculture practices, since the antibiotics used in both human as well as veterinary medicines have been tried experimentally to treat bacterial infections of fish. However, the evolving resistance of fish pathogenic bacteria to existing antibiotics has necessitated development of new alternatives. In the last three decades the discovery of metabolites with biological activities from algae has increased significantly. In this study, sixteen extracts from four algae of genusEucheumawere tested byin-vitroagainst five pathogenic bacteria (Aeromonas salmonicida, Aeromonas hydrophila, Pseudomonas anguilliseptica, Vibrio anguillarumandYersinia ruckeri). The algae were extracted in Soxhlet apparatus using solvents with increased polarity (hexane, dichloromethane, methanol and water) for 24 h. The extract solutions were then evaporated and liophilized before using for the antibacterial test with agar diffusion method. The results revealed that three of four extracts (hexane, dichloromethane and water) were active against all pathogens, while methanol did not. The highest activity was shown by water extract, followed by the hexane and the dichloromethane extracts with lower activities. The water extract ofEucheuma spinosumhad a broad activity since it was active against four of five pathogenic strains.Vibrio anguillarumandPseudomonas anguillasepticawere the two most susceptible pathogens, while the most resistant was presented byAeromonas hydrophila. The screening results confirm that algae were potential to be developed as a source of antibacterial compounds or as a health-promoting food for aquaculture.

Published: September 2020

Abstract
Coastal and island communities depend heavily on marine resources for their food and income. During the west monsoon (September to February), fishermen rarely go to sea, and their activities are limited to the small-scale fisheries, including gleaning the Enhalus acoroides fruits. Participants in this small-scale fishery sector are mainly women; with little or no skill required, these gleaners are often overlooked by the district level fisheries-related census. This case study focused on the role of coastal women with different levels of knowledge and utilization of E. acoroides in three cities/districts of South Sulawesi. This study aimed to determine the contribution of E. acoroides fruit collection to coastal community livelihoods and food security, to identify the impacts, and to seek alternative solutions for seagrass management. Qualitative methods were used to gather information on E. acoroides fruit collection, fishery knowledge, livelihood contributions, perceptions of seagrass condition, and alternative management solutions. Around 90% of E. acoroides fruit collectors were women aged between 30 to 80 years old. Women contribute greatly to livelihoods and food security in coastal areas because they play dominant roles in household affairs and the sale of fishery products. Unfortunately, the methods currently used for collecting E. acoroides fruit can be destructive and may have contributed to the decline in seagrass cover. However, prohibiting the collection of E. acoroides would not be an appropriate solution. A win-win solution is needed to empower women while simultaneously managing seagrass ecosystems sustainably.
Early maturity of Sandfish Holothuria scabra offers more prospective broodstock supply of a commercially important aquaculture species

Published: September 2020

Abstract
The supply of broodstock is a critical limitation on aquaculture of the commercially important sea cucumber Holothuria scabra. Previous research reported that H. scabra mature at a size of more than 450 g. This size is questionable because biologically primitive organisms such as H. scabra mature relatively early. This study aimed to analyze the size at first maturity of H. scabra. The first sexual maturity was analysed by dividing the H. scabra by weight with 25 g weight class intervals, resulting in 12 weight groups. The size at first sexual maturity was determined using mature H. scabra (Stages III, IV, and V). The first maturity of H. scabra was reached at a smaller size than previously reported, from 178 H. scabra that were observed, the first sexual maturity is achieved at 42 g gutted body weight. Small H. scabra potentially used as broodstock, which will produce H. scabra seeds in hatcheries. Although small in size, H. scabra mature can reproduce, of course, with a smaller reproductive capacity. Small size at the first sexual maturity offers the potential for dramatic improvements in the procurement of broodstock stock, by providing a much more accessible supply of H. scabra prospective broodstock.

Abstract
Anatomical structure, fiber dimension, and several physical properties of the 13 years old solomon-clone teak (Tectona grandis) wood planted in Bogor District, West Java Province, Indonesia have been studied. Macroscopic characteristics were observed directly by handy loupe, while microscopic characteristics were observed through microtome specimens. Fiber morphology was measured through maceration specimens, while physical properties were measured by modification of British Standard 373.1957. Results showed that anatomical structure and fiber length of this solomon-clone teakwood were not significantly different from those of common teakwood. The wood consists of 53% fiber, 29% vessel, 10% axial parenchyma, and 8% ray parenchyma; with 905.44-1199.36 μm fiber length and 2.50-6.72 μm cell wall thickness. Average of wood density and specific gravity was 1.04 g/cm3 and 0.51, respectively. Compared to those of 29 years old conventional teakwood as well as 4 and 5 years old faster grown teakwood planted at the same area, specific gravity of this wood was higher. In general, this solomon-clone teakwood is suitable as raw material for wooden furniture manufacturing. This wood is classified as the Strength Class of III, has decorative figures, wood grain is straight, wood texture is fine and even, lower in volumetric shrinkage, and without crystal or silica.
Inspiratory muscle training for improving inspiratory muscle strength and functional capacity in older adults: a systematic review and meta-analysis
Authors: Manifield James , Winnard Andrew , Hume Emily , Armstrong Matthew , Baker Katherine , Adams Nicola , Vogiatzis Ioannis , Barry Gill 
Published: September 2020

Abstract

Background
The ageing process can result in the decrease of respiratory muscle strength and consequently increased work of breathing and associated breathlessness during activities of daily living in older adults.

Objective
This systematic review and meta-analysis aims to determine the effects of inspiratory muscle training (IMT) in healthy older adults.

Methods
A systematic literature search was conducted across four databases (Medline/Pubmed, Web of Science, Cochrane Library CINAHL) using a search strategy consisting of both MeSH and text words including older adults, IMT and functional capacity. The eligibility criteria for selecting studies involved controlled trials investigating IMT via resistive or threshold loading in older adults (&gt;60 years) without a long-term condition.

Results
Seven studies provided mean change scores for inspiratory muscle pressure and three studies for functional capacity. A significant improvement was found for maximal inspiratory pressure (PImax) following training (n = 7, 3.03 [2.44, 3.61], P = &lt;0.00001) but not for functional capacity (n = 3, 2.42 [−1.28, 6.12], P = 0.20). There was no significant correlation between baseline PImax and post-intervention change in PImax values (n = 7, r = 0.342, P = 0.453).

Conclusions
IMT can be beneficial in terms of improving inspiratory muscle strength in older adults regardless of their initial degree of inspiratory muscle weakness. Further research is required to investigate the effect of IMT on functional capacity and quality of life in older adults.
