Bridging a new concept of fisheries subsidies policy to support sustainable fisheries in Indonesia
Authors: Nur Muhammad 
Published: December 2019

Abstract
Indonesia protested the policy of the WTO, which required the abolition of subsidies. Therefore, Indonesia, through the Ministry of Maritime Affairs and Fisheries and the Ministry of Foreign Affairs then attempted to roll out an exception to the WTO provisions. At the 11th Ministerial Conference in Buenos Aires, Argentina, the ministers of the member countries of the WTO agreed to accommodate the interests pursued by Indonesia to review the application of fisheries subsidies. This research then analyzes fisheries subsidies practice in Indonesia. Overall, the results of this study indicate that the policy of fisheries subsidies implemented by the government has not been planned with good policies and management so that the subsidy has an impact on overfishing, overcapacity or IUU Fishing. Therefore, the author initiated the Co-management of Green Fisheries Subsidy policy. The core of this idea focuses on the management of fisheries subsidies that support the sustainability of fisheries resources involving various relevant stakeholders. This idea uses seven principles which are then applied in the stages of establishing a policy of providing subsidies in each region based on the bottom-up principle so that the implementation of subsidies will be more effective and efficient based on the needs of each region. The author uses a normative juridical research method by examining library materials or other secondary materials. The author uses the literature study. The tools used are documents in the form of primary, secondary, and non-legal materials. The data obtained were analyzed qualitatively, then presented descriptively.

Abstract
Tuna fisheries in Morotai Island have great potential economic value. The production of Tuna in 2016 as much as 325 tons. This condition then made Tuna as the superior commodity in this territory [3]. Know the productivity and the pattern of tuna fishing season can maximize tuna production in Morotai Island. The purpose of this research was to investigate the productivity and Yellowfin Tuna fishing season in Morotai Island waters. The study used a survey method by conducting, the preliminary study in June 2018, and collecting data in the field during July-August 2018. The primary was obtained from fishing results data, numbers of the fishing trip from Tuna’s fishers. For the time series secondary data were derived from DKP Morotai Island is the time series data year 2009-2016, DKP Province Maluku Utara, The Log Book of Pacific Tuna Fishers Cooperative, and BPS Morotai Island. The analyzing consisted of CPUE analysis and time series (moving average) analysis. The research results showed that productivity catching Tuna is 0.798 tons/year. Although the productivity in every year was fluctuating but have a low trend, because of the catching of Tuna in Morotai Island used motorboat with small capacity, which is 1,5-3 GT. The analysis results of time series (moving average) analysis showed that the season for fishing Tuna happened throughout the year, with the peak of season happened in March and June.

Abstract
Seaweed is one of the marine biotas that has several benefits for health and cosmetics. The objective of this study was to isolate and test the activity of chloroform fraction of Sargassum hystrix seaweed extract in inhibiting the α-glucosidase and identification of the active fraction compounds. S. hystrix was extracted by maceration, then partitioned using chloroform and methanol. The chloroform fraction was further separated by column chromatography to obtain purer compounds. The extract of S. hystrix, chloroform fraction resulting from partitioning and chloroform fractions from column chromatography were tested for inhibitory activity against the α-glucosidase. The active chloroform fraction inhibits the α-glucosidase then identified its compounds using Gas Chromatography-Mass Spectrophotometry (GC-MS). The result showed that chloroform fraction (IC50 = 0.726 mg/mL) had a higher inhibitory activity of the α-glucosidase than acarbose (IC50 = 1.890 mg/mL). Column chromatography separation produced seven chloroform fractions. The highest inhibition activity was found in the second chloroform fraction (41.62%), third (51.39%), and fourth (30.49%). Based on GC-MS analysis, several compounds were thought to be able to inhibit the α-glucosidase. The identified compounds were 2-Hexadecene-1-ol, 3,7,11,15-tetramethyl-; Hexadecanoic acid, methyl ester; 9-Octadecenoic acid, methyl ester; Phytol; Stigmasta-5,24(28)-dien-3-ol, (3.beta,24Z)- and 6-Hydroxy-4,4,7a-trimethyl-5,6,7,7a-tetrahydro benzofuran-2 (4H )-one.

Published: December 2019

Abstract
This study aimed to determine the quality of commercial fish floss in the Yogyakarta region based on the similarity and dissimilarity in the dominant spices perceived by panelists. Projective mapping (PM) or napping has attained much attention in recent literature as a method for fast sensory profiling and measurement of consumer perception. Configurations from PM have been shown to provide similar product maps. Observation of projective mapping was carried out on ten commercial fish floss using 80 untrained panelists. Panelists were instructed to group samples according to their perception in a sheet flat area 60 × 60 cm2. The coordinates of the grouping sample were recorded. Results of the study were able to detect 12 flavored spices obtained; samples were scattered in four groups of dominant herbs. Fish floss AK, KF_T, and DE contain nutmeg, turmeric, tamarind, and ginger as the dominant flavor. The brands N_S, TS, and SM exhibit dominant taste of fish flavor, candlenut, lemongrass, and a slight chili. N_L, SR, and KF_L had the dominant taste of bay leaves, coriander, cutcherry, and chili. SF_S brand had a dominant flavor of galangal. The result of this study can be used as a reference for the development of the fish floss industry in the Yogyakarta area for new industries and the destination of new products from various raw materials of fish.

Optimization of temperature and time in carrageenan extraction of seaweed (Kappaphycus alvarezii) using ultrasonic wave extraction methods
Authors: Mahyati  , Azis Abdul 
Published: December 2019

Abstract
Carrageenan is a hydrocolloid compound from Rhodophyceae extraction of K. alvarezii using alkali solvents. Conventional extraction methods that have been using certain solvents in large volumes require a long time and low yields resulting in high production costs and large amounts of waste which pollute the environment. These adverse effects can be minimized by extraction with the help of ultrasonic waves which will provide an intensive stirring effect to damage the cell walls of seaweed so that the process of mass transfer will be faster. The extraction temperature greatly influences the quantity and quality of carrageenan which is often carried out in conventional extraction. In carrageenan extraction activities from K. alvarezii with the help of ultrasonic waves, the effects of temperature and time on these two parameters will also be studied. This activity was conducted to determine the time and temperature of carrageenan extraction from K. alvarezii seaweed using an ultrasonic frequency of 40 kHz with temperature variations of 30, 40, 50, 60, and 70 °C, and time variations of 20, 25, 30, 35 and 40 minutes. The results of extraction of K.alvarezii seaweed with a time variation of 40 minutes and temperature variation is 70 °C, with the optimum value of temperature and extraction time is 70 °C for 30 minutes which produces carrageenan as much as 44.46%. The carrageenan quality test produced water content ranging from 6.27-14.18%, ash content 12.33-13.69%, viscosity of 10.4-27.9 cP and gel strength ranged from 926.26 to 4945.99 dyne / cm2.

Abstract
“RRD” field is one of the hydrocarbon prospects in North West Java Basin. One of the potential oil reserves in this field was found on Talang Akar Formation Z.2260 layer and indicated by the presence of oil show on drill steam test data. Physical parameters such as acoustic impedance, porosity and hydrocarbon saturation are essential to determine the distribution of reservoir layer. Acoustic impedance can distinguish the reservoir and non-reservoir zone, while porosity and hydrocarbon saturation can be used in the calculation of oil reserves on the layer Z.2260. Model Based Inversion was performed to find out the lithology distribution determined by acoustic impedance. Porosity distribution was identified using crosspiot acoustic impedance and porosity analysis while hydrocarbon saturation distribution was determined using cokriging geostatistical analysis. The result shows the existence of sandstone reservoir with acoustic impedance values ranging from 8500-10.000 (m/s)(g/cc) that spreads over 2 zones in the research area of anticline zone A and R. Sandstone with such acoustic impedance range has a porosity value of 8-12% and hydrocarbon saturation 25-50%. The reservoir zone A has value 0,201 (MMbbl) as well as R area 1,689 (MMbbl).

Abstract
“KHM” structure is one of PT. Pertamina EP oil producing field in Subang, North West Java Basin. One of the hydrocarbon producers of this structure is located in thin bedded Early Miocene carbonate reservoir which in Upper Cibulakan Formation. The thin bedded reservoir becomes a challenge because the post stack time migration seismic resolution can’t resolve the each layer. To distinguish and delineates the reservoir’s lateral continuity needed spectral decomposition analysis. This analysis obtained 3 best frequencies to acquire a better imaging which known as tuning cube, they are 15 Hz, 20 Hz, and 25 Hz . Furthermore, these frequencies were blended to get spectral decomposition volume. The volumes have same frequency and amplitude with post stack time migration seismic data, so it can be used for further interpretation. To predict the distribution and depositional facies of Early Miocene carbonate, performed seismic interpretation by using model based acoustic impedance inversion on spectral decomposition volume and porosity analysis. The result of this study suggest the lateral distribution of Early Miocene carbonate can be characterized. Acoustic impedance zone that associated with porous carbonate have ranges values of 8050 - 9800 gr/cc ml. This is supported by petrophysics analysis that generates porosity values of 7.4 - 13.9 % in this zone. The relationship of both analysis based on the correlation of well, known that porous carbonate was deposited on a shelf margin facies.
Accurate prediction of protein beta-aggregation with generalized statistical potentials
Authors: Orlando Gabriele , Silva Alexandra , Macedo-Ribeiro Sandra , Raimondi Daniele , Vranken Wim 
Published: December 2019

Abstract

Motivation
Protein beta-aggregation is an important but poorly understood phenomena involved in diseases as well as in beneficial physiological processes. However, while this task has been investigated for over 50 years, very little is known about its mechanisms of action. Moreover, the identification of regions involved in aggregation is still an open problem and the state-of-the-art methods are often inadequate in real case applications.

Results
In this article we present AgMata, an unsupervised tool for the identification of such regions from amino acidic sequence based on a generalized definition of statistical potentials that includes biophysical information. The tool outperforms the state-of-the-art methods on two different benchmarks. As case-study, we applied our tool to human ataxin-3, a protein involved in Machado–Joseph disease. Interestingly, AgMata identifies aggregation-prone residues that share the very same structural environment. Additionally, it successfully predicts the outcome of in vitro mutagenesis experiments, identifying point mutations that lead to an alteration of the aggregation propensity of the wild-type ataxin-3.

Published: December 2019

Abstract

Summary
popSTR2 is an update and augmentation of our previous work ‘popSTR: a population-based microsatellite genotyper’. To make genotyping sensitive to inter-sample differences, we supply a kernel to estimate sample-specific slippage rates. For clinical sequencing purposes, a panel of known pathogenic repeat expansions is provided along with a script that scans and flags for manual inspection markers indicative of a pathogenic expansion. Like its predecessor, popSTR2 allows for joint genotyping of samples at a population scale. We now provide a binning method that makes the microsatellite genotypes more amenable to analysis within standard association pipelines and can increase association power.

A note on the accuracy of adaptive Gauss–Hermite quadrature
Authors: Jin Shaobo , Andersson Björn 
Published: December 2019

SummaryNumerical quadrature methods are needed for many models in order to approximate integrals in the likelihood function. In this note, we correct the error rate given by Liu & Pierce (1994) for integrals approximated with adaptive Gauss–Hermite quadrature and show that the approximation is less accurate than previously thought. We discuss the relationship between the error rates of adaptive Gauss–Hermite quadrature and Laplace approximation, and provide a theoretical explanation of simulation results obtained in previous studies regarding the accuracy of adaptive Gauss–Hermite quadrature.

Abstract
The corpus callosum is the commissural bridge of white-matter bundles important for the human brain functions. Previous studies have analyzed the structural links between cortical gray-matter networks and subregions of corpus callosum. While meaningful white-matter functional networks (WM-FNs) were recently reported, how these networks functionally link with distinct subregions of corpus callosum remained unknown. The current study used resting-state functional magnetic resonance imaging of the Human Connectome Project test–retest data to identify 10 cerebral WM-FNs in 119 healthy subjects and then parcellated the corpus callosum into distinct subregions based on the functional connectivity between each callosal voxel and above networks. Our results demonstrated the reproducible identification of WM-FNs and their links with known gray-matter functional networks across two runs. Furthermore, we identified reliably parcellated subregions of the corpus callosum, which might be involved in primary and higher order functional systems by functionally connecting with WM-FNs. The current study extended our knowledge about the white-matter functional signals to the intrinsic functional organization of human corpus callosum, which could help researchers understand the neural substrates underlying normal interhemispheric functional connectivity as well as dysfunctions in various mental disorders.
