PEMANFAATAN ANTOSIANIN SEBAGAI INDIKATOR PADA SMART FILM PACKAGING UNTUK MENDETEKSI KESEGARAN PRODUK PANGAN

Antosianin merupakan pewarna alami yang larut dalam air dan sensitif terhadap perubahan nilai pH lingkungan. Pigmen antosianin dapat diperoleh dari ekstrak buah-buahan, sayuran, dan bunga. Antosianin termasuk ke dalam kelompok senyawa bioaktif dan senyawa fenolik yang memberikan warna ungu, merah, biru, dan oranye. Produk pangan rentan mengalami kerusakan selama proses penanganan yang kurang baik. Kerusakan produk pangan umumnya disebabkan oleh kelompok mikroorganisme. Penggunaan indikator antosianin pada smart film packaging bertujuan untuk memonitor kesegaran bahan pangan yang dikemas secara “real time”. Indikator antosianin dapat menujukkan tingkat kesegaran produk pangan berdasarkan perubahan warna film yang dipicu oleh perubahan nilai pH lingkungan. Beberapa penelitian terbaru meneliti tentang pengembangan smart film packaging berbasis pigmen antosinain sebagai indikator serta penggunaan polimer ramah lingkungan sebagai bahan baku film. Tujuan dari review ini adalah mengulas pemanfaatan pigmen antosianin sebagai indikator smart film packaging dalam upaya meningkatkan keamanan pangan dan mempertahankan kualitas produk pangan

Voluntary Information Disclosure and Corporate Governance: The Empirical Evidence on Earnings Forecasts

This study investigates the determinants of companies' voluntary information disclosure. Employing a large and unique dataset on the companies' own earnings forecasts and their frequencies, we conducted an empirical analysis of the effects of a firm's ownership, board, and capital structures on information disclosure. Our finding is consistent with the hypothesis that the custom of cross-holding among companies strengthens entrenchment by managers. We also find that bank directors force managers to disclose information more frequently. In addition, our results show the borrowing ratio is positively associated with information frequency, suggesting that the manager is likely to reveal more when his or her firm borrows money from financial institutions. However, additional borrowings beyond the minimum level of effective borrowings decrease the management's disclosing incentive.Voluntary information Disclosure, Corporate Governance, management earnings forecast

Value Relevance & Predictive Value of Comprehensive Income from Entities Listed in Ise

After the convergence of IFRS in Indonesia, according to Statement of Financial Accounting Standards 1, economic entity are obliged to provide information about comprehensive income in their financial statement. The change of regulation is expected to increase earning quality, measured by value relevance and predictive value. The purpose of this research is to know deeper about the impact of IFRS convergence in Indonesia, especially related to the presentation of comprehensive income, to the quality of net income and comprehensive income, measured by value relevance and predictive value. Further, the value relevance and predictive value of comprehensive income will be compared to the value relevance and predictive value of net income. This research used the quantitative approach, with the sample from entities listed in Indonesia Stock Exchange in the year of 2011-2014, except for financial sector firm. The result shows that there are significant value relevance and predictive value whether for comprehensive income or net income. But, if the value relevance and predictive value of both incomes are compared, the finding show that net income is superior to net income. But it is important to note that the superiority of net income compared to comprehensive income is not significant

The results showed that the size of the company is not able to moderate the relationship between leverage agains delays in financial reporting

Safety problems in urban cycling mobility. A quantitative risk analysis at urban intersections

The attention to the most vulnerable road users has grown rapidly in recent decades. The experience gained reveals an important number of cyclist fatalities due to road crashes; most of which occur at intersections. In this study, dispersion of trajectories in urban intersections has been considered to identify the whole conflict area and the largest conflict areas between cars and bicycles, and the speeds have been used to calculate exposure time of cyclists and reaction time available to drivers to avoid collision. These data allow the summary approach to the problem, while a risk probability model has been developed to adopt an elementary approach analysis. A quantitative damage model has been proposed to classify each conflict point, and a probabilistic approach has been defined to consider the traffic volume and the elementary unit of exposure. The combination of damage and probability, permitted to assess the risk of crash, at the examined intersection. Three types of urban four-arm intersection, with and without bike paths, were considered. For each scheme, the authors assessed the risk of collision between the cyclist and the vehicle. The obtained results allowed the identification of the most hazardous maneuvers and highlighted that geometry and kinematics of traffic movements cannot be overlooked, when designing an urban road intersection. The strategy proposed by the authors could have a significant impact on the risk management of urban intersections. The obtained results and the proposed hazard estimation methodology could be used to design safer intersections

Semantic Adversarial Attack on Support Vector Machine

Despite the breakthroughs in machine learning, most classifiers are not robust against adversarial attacks. They can be easily fooled by adversarial examples. These examples can be created in a variety of ways. In this thesis, the ideas of detecting edges or critical pixels in an image are investigated that could be used for fooling classifiers. Identifying those critical pixels in an image can lead the way to fix the vulnerabilities and thus making it robust against cyber-attacks. For testing, a Support Vector Machine (SVM) is used to see the success of the adversarial examples generated

Biomethanation of Invasive Water Hyacinth From Eutrophic Waters as a Post Weed Management Practice in the Dominican Republic: A Developing Country

Anaerobic digestion of water hyacinth (Pontederia crassipes Mart.) from eutrophic water bodies could be a sustainable post weed management practice to generate bioenergy. Comparative analyses of the water quality, physicochemical characteristics, and biomethanation kinetics of water hyacinth from two sites with different water types (brackish versus freshwater) in the Ozama river, Dominican Republic, were conducted. Also, the energy produced from the anaerobic digestion and that consumed in harvesting was estimated. The highest non-structural components in the form of protein (18.8 ± 1.9%) and extractives (26.4 ± 0.1%) were found in brackish water hyacinth, whereas that from freshwater had the highest amount of holocellulose (41.2 ± 2.8%). Indicators of plant productivity, i.e., chlorophyll b and bulk density, were more than 30% higher in brackish than in freshwater hyacinth. The methane production rate in the digestion of water hyacinth from brackish water (22.5 N. L/kg VS added\u27 day) was twice that from freshwater (10.0 N. L/kg VSadded\u27 day). The higher nutrient content in the brackish water could have influenced the superior performance of water hyacinth from that source compared with that from freshwater. Overall, the maximum methane potential of the Ozama river water hyacinth was 399.2 ± 32.2 N. L CH4/kg VSadded. The estimated energy produced per ton of fresh biomass was 846.5 MJ, but only 57.9 MJ would be required for mechanical harvesting. The biomethanation of water hyacinth can mitigate weed management costs in developing countries
