Abstract

Mangrove has numerous ecological functions, such as a habitat for various biota, a place of care and rearing, with a microclimate regulator and spawning. This ecosystem can store the highest carbon compared to tropical, subtropical, and boreal forests. This research aimed to model the estimation of mangrove carbon stocks using drone images. The method used consists of several steps as follows: (1) Taking and analyzing drone images, (2) Identification and estimation of biomass with carbon stocks, (3) Modeling of mangrove carbon stock using drone and field data. The results of mangrove carbon estimation using logarithmic regression of drone images were the best, by the equation y = 0.0455ln (x) + 0.244. Therefore, the results showed that the R2 value was 0.7454, with the RMSE accuracy-test being 689.9 kg, at 35.4%.Keywords:DronesMangroveCarbon stock

Abstract

The shipyard industry plays an important role in supporting fishing activities and efforts to fulfill animal protein for humans. It is an industry that has an orientation to produce a product in the form of a ship. There are two types of shipyards, which are offshore buildings and floating buildings - both are used to build new ships and repair old ships. Based on the level of technology used by the shipyard industry, it is divided into modern, traditional, and semi-modern shipyards. Its productivity can see the advantages and disadvantages of a shipyard to ensure this industry remains to exist. Several factors need to be taken into account to increase the shipyard productivity, including land or location, human resources, technology, and materials.Keywords:ProductivityShipyardTechnology

Abstract

Barramundi (Lates calcarifer) is one of the commercial fish in Indonesia. The phenomenon of climate change due to global warming has affected the life of aquatic biota, including fish. The objectives of the present study were to determine a critical thermal maximum (CTMax) and the behavior of Barramundi (L. calcarifer) due to the increase in water temperature. The research was conducted at the Fishing Technology Laboratory, Faculty of Marine and Fisheries, Universitas Syiah Kuala in February 2021. The experiment was conducted in 10 aquariums equipped with heaters. The initial temperature of the treatment was 28oC and increased gradually every one minute by 0.2oC. The results showed that the abnormal behavior of Barramundi fingerling was started to appear at 37oC where the fish began to swim fast, then swim sideways at 38oC-39oC, hit the container wall at 39oC-40oC, jumped and weakened then dead at 40oC and 41oC. The average critical temperature of Barramundi fingerling was recorded at a temperature of 41oC within 65 minutes. Therefore, it is concluded that the Barramundi (L. calcarifer) display an abnormal behavior above the temperature of 35oC, however, they can survive up to 42oC exposure for 70 minutes.Keywords:Critical thermal maximumTemperature riseGlobal warming

Abstract

The waters of Palabuhanratu Bay are fertile and rich with fish resources. For a long time, fishermen have used the fish resources in these waters. Hairtail (Trichiurus sp.) was one of the fish resources in Palabuhanratu Bay that caught by fishermen using handlines. Fishery production landed at Palabuhanratu Fishing Port in 2019 was 5,414,240 kg with a total hairtail production of 314,107 kg. The problem raised in this study was knowing the right hairtail fishing season so that it provides optimum benefits for fishermen. In addition, knowing potential fishing areas could assist fishermen in choosing their fishing time and fishing ground. The purpose of this study was to describe the hairtail fishing unit, to analyze the catch composition of handline, to analyze the fishing season patterns of hairtail fish, and to analyze hairtail fishing ground in Palabuhanratu bay. The results of the analysis showed that the fishing season for hairtail (Trichiurus sp.) in the waters of Palabuhanratu Bay lasts for 5 years with the peak in October. However, the reality is that fishing operations can be carried out throughout the year. The average catch per unit effort (CPUE) of hairtail (Trichiurus sp) duringfishing seasons was 11.32 kg/trip in 2019. The potential fishing ground was in the waters of West Ujung Genteng, Southern waters of Sawarna, Southern waters of Karanghawu and the waters of West Ujung Karang Bentang.Keywords:Fishing season patternHairtail fishFishing groundPalabuhanratu Bay

Abstract

Global biodiversity, especially fish, has experienced a decline, this occurs as a result of over-exploitation, the presence of introduced fish species and climate change. This condition makes researchers look for solutions to overcome these problems by using cryopreservation techniques. The main purpose of cryopreservation is to store, maintain, and ensure the survival of genetic material, so that using cryopreservation techniques can maintain the viability and function of gamete cells both immunologically, biologically and physiologically. The success of the cryopreservation technique has made this technique widely developed in various species of living organism including fish. This article summarizes and reviews the history of the development of cryopreservation of animal species with specific focus on fish.Keywords:CryopreservationHistoryDepikEndemic species

Abstract

Several marine research have attempted to design a data observation system using Internet of Things (IoT). In the future, this system is predicted to become a necessity for marine researchers as a strategic technology to continuously access data. Therefore, this study provides information on the development and application of observation and data collection systems using IoT. The coastal weather and tidal data were obtained via the automatic coastal weather station and acoustic gauge respectively. Meanwhile, the various research activities commenced in July, 2018. In the first year, an operational observation system was developed, while comprehensive baseline data such as air temperature, humidity, wind speed, and sea surface level were also collected. This collection system is reliable, provides real-time data, and easily accessible with internet connection. Furthermore, the Bintan Marine Observation System (The Bintan MOS) is also suitable for other uses such as; monitoring water quality and marine mammals, as well as disaster mitigation. The adoption of this system by other sectors potentially conditions marine researchers for data exchange, to fully understand the fluctuations in coastal weather of Western and Eastern Indonesia as well as the tropical and sub-tropical marine weather. This study successfully developed the Bintan MOS, capable of providing reliable information both off-line and real-time.Keywords:Marine observation systemCoastal weatherTidalBintan

Abstract

The active operation of a trammel net by a sweeping technique is commonly used by fishermen in Cilacap, which are often referred as ciker nets. They are operated by lowering the net in a straight line and pulling the tail end from a ship moving in a full circle, while the other end functions as a circular axis. The effect of active operation allows for changes in performance with time, such as easy lifting or less buoyancy, and the unstable display of gears. This makes it necessary to perform design engineering, especially on buoys, sinkers, and high nets. However, the suitable quantity of these components for ciker net has never been ascertained. Calculations about how many buoys, sinkers, and net height to add need to be done to enhance ciker net construction for active operation. This research aimed to determine the optimum configuration of buoys, sinkers, and net height, and determine the engineering design of ciker nets based on the optimum ratio of buoyancy force to the sinking force of the trammel net. Therefore, the parameters measured include hanging ratio, stretched net length, buoyancy force, and sinking force. The results showed that the optimum configuration of buoys, sinkers, and net height was 59 pieces, 341 pieces, and 1.5 m respectively. Changes in the design of ciker nets, especially in the three components that affect the addition of buoyancy and sinking force ratio were based on the comparison of the trammel nets which was 1:5 greater than the design owned by fishermen at 1:4.Keywords:Bouyancy forceSinking forceCiker netTrammel netShrimp

Abstract

A 28-days trial was conducted in an aquaponics culture system to determine the effect of the different vegetable plants application on the growth performance and survival rate of common carp (Cyprinus carpio). Common carp seeds were obtained from local fish farmers in Aceh Besar District. A total of 360 common carp fingerlings (size 3-5 cm) were used and placed in 12 containers with the capacity of 80 L each. The study used four treatments, namely A (control), B Kale (Ipomoea aquatica), C Lettuce (Lactuca sativa), and D Pakcoy (Brassica rapa subsp. chinensis), with three replications for each treatment. The result showed that different vegetable plants' applications significantly affected (P 0.05) the absolute weight gain, absolute length gain, and survival rate of common carp fingerlings. The highest value obtained was in treatment B (Ipomoea aquatic) with an absolute weight gain of 3.93 ± 0.28 g, absolute length gain of 3.81±0.21 cm, and survival rate of 100±0.0%, while the lowest was in treatment A (control) with an absolute weight gain of 1.21±0.76 g, absolute length gain of 1.70±0.10 cm and survival rate of 91±0.86%. Water quality was also collected in this study and the parameters during rearing were still within the tolerance limits of common carp rearing. Therefore, it can be concluded that the Kale plant, Ipomoea aquatica is the most recommended vegetable plant to be co-cultured with common carp in the aquaponics system.Keywords:AquaponicsCommon CarpVegetable Plants

Abstract

 The purpose of this study was to identify the tiger shrimp (Penaeus monodon) histopatology status in traditional cultured ponds at Bireuen Regency, Aceh Province. The sampling was carried out by purposively random method from seven ponds and two shrimps were sampled from each pond. Several water quality parameters were checked like temperature, pH, salinity and ammonia. Result showed that black tiger shrimp (Penaeus monodon) which were cultivated in traditional ponds in the Bireuen Regency, Aceh Province were histopathologically changes. It was suspected the hepatopancreas changes were associated with viral infection like Hepatopancreatica Parvovirus (HPV) and White Feces Disease (WFD). Ammonia concentrations were found higher in some ponds like Alu Buya Village, Jangka Keutapang Village, Jangka Mesjid Village, Alu Kuta Village and Punjot Village. The management of regular feeding and water quality control is highly recommended to anticipate the viral potential attack in traditional shrimp pond farming at Jangka District, Bireuen Regency, Aceh Province.Keywords:Tiger shrimps Histopathology Water quality

Abstract

Limited information about Mollusks in Menganti Beach, Central Java has been a strong basis for researching its diversity. This study aimed to determine the mollusks' diversity in Menganti Beach, Kebumen. The research was conducted from April to May 2020, using a survey method and purposive sampling technique. Sampling was undertaken at three stations with the belt transect method. The results revealed 37 species with 1767 individuals from the Class Bivalvia, Gastropods, and Polyplacophora. Based on the diversity index value H '= 3.3, station 1 with the rocky sand substrate is the best for mollusks' habitat. The H' value at station 1 shows the highest diversity that the base substrate is dominated by sand and rocks, which are very supportive of mollusks. It is supported by the evenness value (E), which indicates evenly distributed species, and dominance value (D), which does not indicate a species' dominance. The a-biotic parameters at the three stations obtained an average morning temperature of 29 oC and 30 oC in the afternoon, pH of 7, and a salinity of 30 ‰ so that these values support the Mollusk habitat at Menganti Beach, Kebumen.Keywords:MolluskDiversityIntertidal ZonesCoastal
