Published: December 2022

Abstract
Organic matter is one of indicators of environmental fertility in both land and aquatic ecosystem. In the coastal area, the content of organic matter in a certain amount can be useful for aquatic biota, but it can also cause a disturbance if the amount exceeds the assimilation capacity of the waters. This study aims to determine the organic matter content in the water column and sediment at high and low tide conditions in the waters of the East coast of Bengkalis Island as well as to determine their relationships. The study was carried out by survey method where samples and data were collected directly in the field and then were taken to the laboratory for further analysis. The results showed that the mean organic matter content in the seawater was lower at high tide (17.38 mg/L – 25.28 mg/L) than at low tide (29.63 mg/L – 35.55 mg/L), whilst in sediments the organic matter content at high tide conditions was also lower (2.28% - 5.37%) compared to low tide (3.46% - 8.62%). The sediment of the east coast of Bengkalis Island was dominated by mud type (53.62 - 93.94 %). The organic matter content in seawater and sediment showed a strong correlation with r value of 0.730 both during high tide (Y= -1.423 + 0.271X) and also during low tide (Y= -14.912 + 0.615X with r value of 0.844), respectively. Further study is still needed to provide a comprehensive understanding on the sustainable environmental condition of the east coast of Bengkalis Island as it is one of the important fishing ground.

Abstract
The fishing port is an important supporting facility for achieving high-quality of fishery production. Maintaining the quality of fishery products is needed by optimizing the function of fishing ports as they are the cutting edge and a prime mover in the management and utilization of fish resources and port environment, ranging from preproduction, production, processing, and marketing. On the other hand, the fishing port has various environmental problems such as waste management, water quality degradation and liquid waste management. The objective of this study is to identify the solid waste input to a fishing port by using remote sensing approach. The research was conducted in Karangantu Fishing Port (Pelabuhan Perikanan Nusantara Karangantu), located in Serang, Banten. This study shows that the high-resolution satellite imagery was proven to be able to estimate the solid waste input to the fishing port area. The result shows that solid waste input to Karangantu Fishing Port was estimated to be 142.95 tons in 2020, which was derived from office activities, shipping activities, and tourist activities surrounding fishing port area. The method approach from this study is expected to support environmental management in the other fishing port areas.

Abstract
Rhu Bay is located in Rupat Island, Bengkalis Regency, Riau Province, Indonesia, under influence of the Malacca Strait. The main purpose of this study is to analyze shoreline changes in the Rhu Bay Coastal Area for 18 years, from 2012 to 2022 based on characterstics of sediment and physical Oceanography. Analysis of shoreline changes using Google Earth (Landsat Copernicus) covering the entire Rhu Bay area in 2002, 2008, 2014 and 2020. This research was carried out in Rhu Bay in June 2022 through two research stages:1) processing of secondary data in using Lansat Imagery Data and 2) the sediment samples were collected using sediment grab and oceanographic observation (currents, tides and waves) was also carried out at the coast. Digital Shoreline Analysis System (DSAS) is empowered in processing spatial data to calculate the rate of abrasion and accretion in Rhu Bay, using the methods applied of Net Shoreline Movement (NSM) and End Point Rate (EPR). The results of the study show that the coastline changes dominantly in Rhu Bay experiencing abrasion of 7.87 - 11.24 meters/year in a period of 18 years. The oceanographic parameters in Rhu Bay showed that the waves had a height of 0.2 m with a period of 3 second, current velocity of 0.36 m/s to the northwest. The change in shoreline is thought to be due to the current that flows from the Malacca Strait at high and low tide, as well as the transport of coastal sediment (dominated by medium sand fraction) towards the Malacca Strait by the currents.

Published: December 2022

Abstract
Lobster rearing has been widely carried out in Indonesia, especially to prevent a decrease in stocks in nature due to fishing that does not pay attention to the aspect of resource sustainability. However, in the effort to rear lobsters, there are obstacles, namely necrosis to the tail fins of sand lobsters reared with recirculation aquaculture system (RAS) caused by infectious diseases. This research was carried out at the Field Test Facility of Fish Health and Environmental Assessment Center (BPKIL) Serang in June-November 2021. Sand lobsters had an initial size of 50-100 grams which were reared in 1000-L fiberglass tanks with a density of 25 individuals per tank and reared with RAS. Samples from diseased sand lobster after being reared in RAS for 176 days. Necrosis (red color and erosive) can be seen in the tail fins of sand lobsters reared with the RAS. From the results of laboratory tests, it was found that there were parasitic infections of the types of ciliates, protozoa, and vorticella. The results of further testing at the Microbiology Laboratory found that there was an infestation of vibriosis disease caused by the bacteria Vibrio alginolyticus and Vibrio parahaemolyticus. Diseases caused by parasitic and bacterial attacks do not affect mass death in sand lobsters, even these symptoms can disappear if sand lobsters can replace their skin (moulting) perfectly. Observations also show that the most mortality occurred in sand lobsters with smaller sizes (weight ≤100 grams). This disease infection occurred due to a decrease in the water quality of the sand lobster rearing media in RAS, mainly because of the high organic matter concentration in the water.

Abstract
Mangrove Crab (Scylla serrata) is one of the marine commodities that have high economic value. The problem of mangrove crabs is the limited availab ility in nature, so this condition requires cultivation efforts to maintain the population in nature. Panipahan is one of the mangrove crab cultivation sites in Riau Province, which has been going on since 2013. This study aims to analyze the critical factors for the sustainability of mangrove crab farming businesses in the ecological, economic, institutional social and technological dimensions. Data collection techniques are carried out by observation, in-depth interviews and literature studies. The data analysis technique used is Multi-Dimensional Scaling (MDS) through the Rapfish approach. Informants in this study are experts consisting of cultivators, fisheries services and academics. The results of the analysis of the sustainability of the mangrove crab farming business on an MDS basis are in a less sustainable status with a score of 48.13. In the ecological dimension, the critical factor that affects sustainability is the source/availability of seeds. In the economic dimension, sustainability is influenced by business profit factors. In the institutional social dimension, the dominant key factors are the involvement of family members in the mangrove crab business and the potential for conflict. The dimension of technology that affects sustainability is technical assistance from the government and post-harvest handling. Operational steps that can be taken to obtain optimal results for mangrove crab cultivation business management in Panipahan are to carry out policies/programs related to key factors.

Is quantum computing green? An estimate for an energy-efficiency quantum advantage
Authors: Jaschke Daniel , Montangero Simone 
Published: December 2022

Abstract
The quantum advantage threshold determines when a quantum processing unit (QPU) is more efficient with respect to classical computing hardware in terms of algorithmic complexity. The ‘green’ quantum advantage threshold—based on a comparison of energetic efficiency between the two—is going to play a fundamental role in the comparison between quantum and classical hardware. Indeed, its characterization would enable better decisions on energy-saving strategies, e.g. for distributing the workload in hybrid quantum–classical algorithms. Here, we show that the green quantum advantage threshold crucially depends on (a) the quality of the experimental quantum gates and (b) the entanglement generated in the QPU. Indeed, for noisy intermediate-scale quantum hardware and algorithms requiring a moderate amount of entanglement, a classical tensor network emulation can be more energy-efficient at equal final state fidelity than quantum computation. We compute the green quantum advantage threshold for a few paradigmatic examples in terms of algorithms and hardware platforms, and identify algorithms with a power-law decay of singular values of bipartitions—with power-law exponent

Democratic Aesthetics, Aesthetic Democracy
Authors: Greiman Jennifer 
Published: December 2022

AbstractThis essay reviews four new books, each of which assesses the prospects of contemporary democracy in the face of wide-ranging crises—from the legacies of settler colonialism to the resurgence of right-wing nationalism—and finds possibilities for democratic renewal in aesthetic orientations and practices. Taken together, Jason Frank’s The Democratic Sublime (2021), Andrés Fabián Henao Castro’s Antigone in the Americas (2021), Michael Steinberg’s The Afterlife of Moses (2022), and Elisabeth Anker’s Ugly Freedoms (2022) suggest that the aesthetic turn in democratic theory most closely associated with the work of Jacques Rancière has been decisive. But if democratic theorists now fully embrace the centrality of creativity, performative assembly, and affective attachment and aversion to democratic renewal, they do not fully agree on the more fundamental question of whether democracy is a stable form that has aesthetic features or whether it is constitutively aesthetic—in other words, whether its people comes into being in moments of materialization with no prior referent.If contemporary political theorists . . . have found better prospects for the revitalization of democratic politics in collective performance and creative resistance than in . . . legal and political institutions, this shows how seriously . . . democratic thought has come to take democracy’s aesthetic dimensions.
Display site selection in a ground dwelling bird: the importance of viewshed

Published: December 2022

AbstractWe studied the effects of visibility, female and male distribution, microhabitat and distance to human infrastructure on display site selection in a ground-dwelling bird, the Canarian houbara bustard. Using a very high-resolution digital elevation model based on LIDAR technology, and a complete census of the breeding population, we compared 98 display sites with randomly generated sites through generalized linear models. Univariate analyses showed that males displayed at locations that increased their visibility, both at short and long distances. Interestingly, although numbers of females and males around sites did not differ between display and random locations, from display locations males could see more females and males at both distance ranges. The absence of vegetation and stones was also critical as it allowed males to perform display runs on a ground free of obstacles. The amount of trophic resources did not correlate with the selection of the display site itself, though an appropriate vegetation cover seemed to be important at a wider habitat scale. Finally, display sites were farther away than random sites from sources of human disturbance, such as urban nuclei, buildings and tracks. Logistic regression analyses confirmed the importance of viewshed, low stone and vegetation cover, and distance to urban centres and tracks, and model averaging identified short-range visibility and females visible in the long range as the most important visibility variables. These results are compatible with the sexual advertisement and predator avoidance hypotheses. We provide recommendations to ensure an appropriate management of the breeding habitat of this endangered subspecies.
CCSynergy: an integrative deep-learning framework enabling context-aware prediction of anti-cancer drug synergy
Authors: Hosseini Sayed-Rzgar , Zhou Xiaobo 
Published: December 2022

Abstract
Combination therapy is a promising strategy for confronting the complexity of cancer. However, experimental exploration of the vast space of potential drug combinations is costly and unfeasible. Therefore, computational methods for predicting drug synergy are much needed for narrowing down this space, especially when examining new cellular contexts. Here, we thus introduce CCSynergy, a flexible, context aware and integrative deep-learning framework that we have established to unleash the potential of the Chemical Checker extended drug bioactivity profiles for the purpose of drug synergy prediction. We have shown that CCSynergy enables predictions of superior accuracy, remarkable robustness and improved context generalizability as compared to the state-of-the-art methods in the field. Having established the potential of CCSynergy for generating experimentally validated predictions, we next exhaustively explored the untested drug combination space. This resulted in a compendium of potentially synergistic drug combinations on hundreds of cancer cell lines, which can guide future experimental screens.
