Selectivity of Gillnet to Catch Silver Pomfret (Pampus argenteus) in Pangandaran Waters, Indonesia

The purpose of this research was to determine the most selective mesh size of gillnet fishing gear for Pampus argenteus in coastal waters of Pangandaran Regency, West Java. Research on the selectivity of gillnet fishing gear was carried out in the coastal waters of Pangandaran, West Java Province, from August 2018 to January 2019. The method used in this research is experimental fishing, namely operating gillnet fishing gear directly in the fishing area with fishermen. The primary data collected was the measurement of the catch (fish weight, number, fork length, how the fish was caught, circumference (girth opercullum, maximum body girth). Meanwhile, the secondary data collected were supporting data from the Pangandaran District Fisheries and Marine Service, and literature study. In determining the sampling, the method used is the purposive sampling method. The operation of gillnets using 4.5 inches obtained a higher proportion of main catch (75%) than gillnets with a mesh size of 5 inches (44%). Gillnet with a mesh size of 4.5 inches, the silver pomfret caught was distributed between 17-22 cm in size with the highest mode in the 19 cm fork length. Unlike the gillnet fishing gear with a mesh size of 5 inches, the silver pomfret caught was distributed in the fork length range of 17-25 cm with the highest mode in the length class 19 cm fork length. mesh size 4.5 inches has a hanging ratio value of 0.51. Meanwhile, the 5 inch mesh size has a hanging ratio value of 0.54. Based on the length distribution, gillnets with a mesh size of 5 inches were more dominant in catching silver pomfret in a larger size class interval than gillnets with a mesh size of 4,5 inches. Based on the L50 value, both selective gillnets caught more fish at 50% second chance. The selectivity curve shows that gillnet fishing gear with a mesh size of 5 inches has more selective results than gillnets with a mesh size of 4.5 inches.

Gillnet Selectivity on the Narrow-barred Spanish Mackerel (Scomberomorus commerson) Fishery in Pangandaran Waters

Analyzing the selectivity of gillnet fishing gear using two different mesh sizes, namely 3.5 and 4 inches. Gillnets of these mesh sizes are commonly used by fishermen in Fish Landing Base (PPI) Cikidang, Pangandaran Regency, West Jawa. A total of 8 fishing trips were conducted at the coastal waters around PPI Cikidang, Pangandaran Regency, West Java from August 2018 to January 2019 using gillnet fishing gear As for each trip, 2-3 times the operation of the tool is carried out. The operation of the fishing gear is carried out with the help of vessels measuring 2-3 Gross Tonnage (GT). The catch obtained was differentiated based on the main catch and bycatch and the amount is calculated for analysis of the proportion of the catch. Mackerel (Scomberomorus commerson) is caught as the main catch, the fork length was measured for analysis of the length frequency distribution and selectivity curves. The operation of gillnets with a mesh size of 3.5 inches obtained a higher proportion of bycatch compared to gillnets with a mesh size of 4 inches. In addition, the length distribution of mackerel caught by gillnets with a mesh size of 3,5 inches is smaller (27-49 cm FL) compared to a mesh size of 4 inches (40-55 cm FL). Based on the distribution of length distribution, gillnets with a mesh size of 3.5 inches are more dominant in catching mackerel in a smaller size class interval than gillnets with a mesh size of 4 inches. Meanwhile, based on the selectivity curve for the length of mackerel with a 50% chance of being caught, it shows that gillnets with a mesh size of 3.5 or 4 inches are selective in catching mackerel, this is because the chances of catching fish at more than L50 are high.

Toward Development of a Framework for Prediction System of Local-Scale Atmospheric Dispersion Based on a Coupling of LES-Database and On-Site Meteorological Observation

An accurate analysis of local-scale atmospheric dispersion of radioactive materials is important for safety and consequence assessments and emergency responses to accidental release from nuclear facilities. It is necessary to predict the three-dimensional distribution of the plume in consideration of turbulent effects induced by individual buildings and meteorological conditions. In this study, first, we conducted with meteorological observations by a Doppler LiDAR and simple plume release experiments by a mist-spraying system at the site of Japan Atomic Energy Agency. Then, we developed a framework for prediction system of local-scale atmospheric dispersion based on a coupling of large-eddy simulation (LES) database and on-site meteorological observation. The LES-database was also created by pre-calculating high-resolution turbulent flows in the target site at mean wind directions of class interval 10°. We provided the meteorological observed data with the LES-database in consideration of building conditions and calculated the three-dimensional distribution of the plume with a Lagrangian dispersion model. Compared to the instantaneous shots of the plume taken by a digital camera, it was shown that the mist plume transport direction was accurately simulated. It was concluded that our proposed framework for prediction system based on a coupling of LES-database and on-site meteorological observation is effective.

Original Research the use of a Neural Network Classifier of Material Facture Criteria for the Rational Choice of the Method for Cutting of Rolled Stocks

To select a rational method for cutting of rolled stocks made from materials with different physical and mathematical properties, an engineer must have the tools to make such a choice. For this, it is proposed to use the well-known synergistic material fracture criteria. In order to find the most informative system of synergetic criteria allowing to classify materials authentically by their fracture sensitivity, the software was developed. It allows to solve the clustering problem in a multidimensional space of parameters and present the obtained information in a visual form using self-organizing Kohonen maps. The cluster analysis of the synergetic criteria of fracture material was carried out. The most informative criterion among the ones characterizing the mechanical properties of steels is the «offset yield strength», among the synergistic ones – «scale criterion». At the same time, among the traditional mechanical features of steels, a set allowing to classify materials with a given integrity by their cutting sensitivity has not been found. It was established that the synergistic criteria: «crack propagation criterion» and «brittleness criterion» are basic informative features. When adding any of the remaining complex criteria («crack nucleation criterion» or «scale criterion»), they form the most informative sets of minimal power, providing the classification of materials by their cutting sensitivity with a given integrity. In order to obtain high quality billets at a minimum conversion cost, recommendations were developed for choice of the method for cutting of rolled stocks in magnitude of criteria values: «crack propagation criterion» and «brittleness criterion». To cut materials «in plastic state», the cutting with a shear should be used, specifically – a closed cut-off scheme or an incompletely closed cut-off scheme with an active transverse clamp or a cut-off scheme with a differentiated rolling clamp. If increased requirements are imposed on the geometric accuracy of the billets, it is recommended to use complex blanking and cutting processes. For cutting materials «in elastoplastic state» there are good reasons to use a cut with a shear, and in particular – an incompletely closed cut-off scheme with an active and passive transverse clamp. Closer to the class interval, it is possible to apply cold bend breaking with the application of an effective stress concentrator. Cold bend breaking should be used to cut «brittle» materials. The carried out experiments confirmed the adequacy of theoretical conclusions and recommendations on the choice of a rational method for cutting of the rolled stocks to obtain high quality billets.

Transparency of Village Financial Management in Pulau Morotai Regency

This study aims to provide an overview of the transparency of village financial management in Pulau Morotai Regency, North Maluku Province, Indonesia. The sample in this study was taken by using a purposive sampling method, involving 440 respondents, and spread in 88 villages in Pulau Morotai Regency. Data processing techniques used descriptive statistics with a class interval approach. The results show that the indicators of clarity of roles and responsibilities, implementation of government affairs are still dominated by the head of the village who has the authority for village financial management. Indicators of budget disclosure show relatively the same as indicators of clarity of roles and responsibilities. The indicators of information availability indicate that the accessibility of public information in villages located in the subdistrict capital is relatively good. In contrast, the last indicator, integrity assurance, shows that data validity still being a problem in the village planning process. This study also discusses the implications as well as suggestions for future studies.

Landscape Resistance Index Aiming At Functional Forest Connectivity

The terrestrial surface is the basis for defining the species dispersion paths and overcoming the matrix resistance. In this approach, connecting paths with high levels of integrity must avoid barriers and anthropized areas. In this context, the main objective of this study was to develop the Landscape Resistance Index based on environment integrity. It was developed through Structural Equation Modeling (SEM), supported by the criteria of Land Surface Temperature, Nighttime Reflectance, and Inverted NDVI, which are called observed variables. The landscape studied in the Green Belt Biosphere Reserve of São Paulo has suffered from urban sprawl. However, it has significant remnants of the Atlantic Forest, which is a biodiversity hotspot. Our results indicated criteria variability in the landscape, however, modeled through the SEM, obtaining a significant adjustment of the Landscape Resistance Index, with CFI of 1.00 and RMSEA of 0.00. The index reflects the resistance levels of the land-use/land-cover, expressed by the class interval, ranging from 0% (1.73) to 100% (493.88), with the highest values associated with the anthropized uses and forest isolation. This way, the index based on environmental attributes reflects the structure of functional forest connectivity, supporting the planning design of forest corridors across landscapes.

Biometric Condition of Seurukan Fish (Osteochillus Vittatus Valenciennes, 1842) Exposed to Mercury in Krueng Sabee River Aceh Jaya Indonesia

Mercury is a dangerous contaminant for aquatic organisms. Seurukan fish (Osteochilus vittatus) is a type of fish in the Krueng Sabee river that is vulnerable to mercury exposure. The study's purposes were to investigate the effect of mercury on the biometric conditions of Seurukan Fish in the Krueng Sabee River, Aceh Jaya Regency. A total of 90 Seurukan fish consisting of 50 males and 40 females were collected from 3 research stations. The research stations represent the upstream area (Station 1), median river bodies (Station 2), and the downstream area (Station 3). Fish samples were taken from July to August 2019. The main parameters observed included class interval, sex ratio, length-weight relationship, condition factors, mercury concentration in sediment and liver, and hepatosomatic index. The results showed that the mercury content in the sediments of the Krung Sabee River was increased both spatially and temporally. Station 1, located in the upstream area, has the highest mercury content in the sediment was 6.278 ± 0.987 mg/kg. Mercury content in liver of Seurukan Fish ranged from 0.182 ± 0.100 mg/kg to 0.198±0.152 mg/kg. Mercury contamination in the Krueng Sabee river caused a decrease in biometric conditions of Seurukan Fish. Seurukan Fish exposed to mercury tended to have smaller size, an unbalanced sex ratio, low hepatosomatic index value, and negative allometric growth pattern.Abstrak: Merkuri merupakan salah satu jenis kontaminan berbahaya bagi organisme akuatik.

Dairy productivity ewes' karachai breed of sheep and its relation with living mass and vertical zoning of pastures

Milk production and live weight of queens in mountain meat-coarse-wool sheep breeding, as one of the main quantitative traits in postnatal ontogenesis, are more susceptible to the influence of paratypical factors, that is, they have a large “rate of reaction” to the conditions of feeding and maintenance.In order to resolve the question * how to select, what animals to leave for the tribe in the mountain meat coarse-wool sheep breeding *? We at OOO Dargan, a mountainous zone of the Kabardino-Balkarian Republic (KBR), according to the methodology, formed five groups of queens, with a class interval of 5 kg.It was found that the milk production of the queens had a certain relationship with their live weight, and was 32.4 kg in group V, which exceeds the same indicator of group IV by 1.4 kg; III - by 3.0; II - by 7.6; I - by 8.5 kg, the difference between IV and III groups is 0.6 kg.At 4 months of age, the rams of group V in live weight exceeded rams of groups IV and III by 0.7 and 0.4 kg, II - by 2.5 kg, I - by 5.3 kg, at 6 months of age - I at 7.9 kg, II - at 4.0 kg, III - 1.5 kg. There were no significant differences between IV and V groups - 0.7 kg.Along with this, it should be noted that with an increase in the vertical zoning of pastures above sea level (above sea level), with steep slopes, the higher milk production potential of large queens is leveled.The obtained research results indicate that in mountain meat and coarse-wool sheep breeding, selection for increasing the milk yield of ewes, in combination with the optimal live weight, is an effective method of increasing the live weight of young animals.
