Floating net cage activities can cause  water quality to decrease. The feed remains and the metabolism of the fish  from these activities produces nitrogen and phosphorus .  The objective of this study  is to obtain the calculation model and the amount of phosphorus released into the waters of Laut Tawar Lake  as a result of floating  cage activities. The resulting  formula  was Pw = (F x [P]p) – ((It – Io) x [P]i), where their variables were given feed (F), phosphorus concentration of feed ([P]p), the final weight of fish (It), the initial weight of fish (Io), and phosphorus concentration in fishes ([P]i). It can be used to predict the increase in phosphorus waste based on the increase in floating net cage area. The weight of tilapia increases exponentially with the  day of cultivation in the equation Y = 12.70e0.02x and the goldfish followed the formula  Y = 2.28e0.03x. Phosphorus in tilapia varies  from 1.58% to 2.23% with an average of 1.97%. Goldfish contain  1.19 - 2.02% phosphorus, with an average of 1.52%. Goldfish  growth  was not optimal due to inadequate feeding,   so  without excessive feeding and did not generate  phosphorus waste. The cultivation of  tilapia releases  0.09 Kg P/m2 of phosphorus waste from floating cages .

Published: September 2021

Hydrogen is a renewable energy source that can be used as a fuel and as an  alternative to fossil fuels. Solid  storage media in solid form are safer to use than liquid (-253 oC) or gaseous media (700 bar) media. To store hydrogen in a solid medium, it requires a metal able to  interact with hydrogen . Magnesium is one of the metals which  can form metal hybrids based on MgH2 which is capable of  absorbing hydrogen up to  (7.6wt%). However, the reaction kinetics for  magnesium are  very slow, it takes at least 60 minutes to absorb hydrogen and the operating temperature is always  very high (300 oC). Several attempts have been made to add the catalytic converter  and milling time. Hydrogen storage material based on MgH2 with a 10wt%Ni catalyst was  successfully synthesized using a mechanical alloy technique with time variations of 2 hours, 5 hours, and 10 hours. From the results of the X-ray diffraction schema  at a diffraction angle of 2θ=37.87o, it shows the presence of a MgH2 phase, Ni phase is at a diffraction angle of 61.85o, the diffraction peak also shows that there was a  widening of the diffraction peak with increasing milling time, this explains that there was  a reduction in the size of the crystal. When  calculating  with the Schereer method, the crystal size of the material reaches 10 nm. The results of the DSC test indicated  a decrease in temperature of 383 oC in 41 minutes with a milling time of 10 hours.

Fish that are high in protein content are prone to quality degradation. This is strongly thought to be due to the influence of microbes that are inside or outside the fish's body. The use of formalin for food preservatives is not recommended because it can interfere with health. In Indonesia, there are many natural preservatives that are safer to use, such as Murayya koenigii L. Spreng which is rich in antioxidants and has antibacterial properties. This study aimed to evaluate the effect of M. koenigii leaf extract as an inhibitor of bacterial growth in Oreochromis. niloticus fish meat and to measure the maximum concentration of M. koenigii leaf extract. The study used a completely randomized design method (RAL) with one factor, namely the concentration of temurui leaf extract (Murayya koenigii L. Spreng) which consisted of concentrations of 0, 10, 20, 40% (g / mL). The data were taken on storage time, namely 0 days, 1 day, 2 days, and 3 days. The observation parameter used was the inhibition zone diameter (mm) which was analyzed using one way ANOVA. The results showed that temurui leaves have the potential to be used as an inhibitor of microbial growth in O. niloticus fish meat at a concentration of 40% (g / mL) which is the maximum concentration.

Appropriate fertilization in the cultivation of high-yielding varieties has a great opportunity to increase soybean production, especially in soybean centers where areas lack water and ex-paddy fields. An assessment was conducted in Ujong Pie Village, Muara Tiga District, Pidie Regency during the 2020 dry season. The study demonstrated the use of appropriate cultivation technology and superior varieties of Anjasmoro soybean. Plants are managed with integrated crop management (PTT). The land used is land that was previously used for rice planting activities. The study applied five treatments, namely the former fertilized N (P1), K (P2), P (P3), and NPK (P4), as well as the pattern of farmers as control (P5). Pest and disease control is carried out with the principle of IPM. The variables measured were the growth rate of plants and their production components. The results obtained showed that the average plant height during the vegetative period at locations P4 and P5 (P0.05) was higher than those who received other treatments. The maximum growth (height) of plants that received the treatment were 56.33 cm and 54.66 cm. The highest average number of pods per plant occurred in plot P5 and then in P4, 16.50 and 15.00 pods per plant, respectively. The highest average seed production per plant was achieved in plot P5 (18.4 g/plant) and followed by plot P4 (17.13 g/plant) or converted in hectares with an average of 1.82 t/ha and 1, 50 t/ha

Authors: Lynda Golea
Published: September 2021

Pyrazole and its derivatives are contemplated crucial compounds in heterocyclic chemistry which are also used extensively in organic synthesis. These cycles are known for their biological and pharmacological activities. The present investigation is in the interest of some synthesized derivatives containing the pyrazole moieties. (5-Hydroxy-3,5-dimethyl-4,5-dihydro-pyrazol-1-yl)-pyridin-4-yl-methanone (1) and Furan-2-yl-(5-hydroxy-3,5-dimethyl-4,5-dihydro-pyrazol-1-yl)-methanone (2) were synthesized by cyclocondensation of the 1,3-dicarbonyl with the hydrazine derivative with a simple and rapid approach to obtain substituted pyrazole. All structures of these compounds were elucidated by spectral (1H NMR and 13C NMR) analysis. The antibacterial activity of the synthesized compounds was screened against two Gram-positive and Gram-negative bacteria, and all of them displayed moderate activity. The radical scavenging activity of these compounds were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH), the synthetic compounds showed moderate antioxidant activities. In addition, the results obtained from antibacterial activity were further explained with the help of DFT and molecular orbital calculations with a basis set 6-311+G (d, p). The synthesized compounds were docked with 6RKV enzymes with the use molecular docking tools and the docking results are explained all interactions amino acid residue of enzyme and compounds.
Art and Environmental Action, One Bird at a Time
Authors: Cartiere Cameron
Published: September 2021

The environmental problems of climate change and species decline can feel overwhelming. Individuals are often at a loss, questioning what impact they can actually have. Through chART Projects, we have witnessed the dramatic effect of community-engaged art as a direct path to environmental action and impact on local ecosystems. During the 27thInternational Ornithological Congress, bird enthusiasts from around the world focused their attention on Vancouver, Canada. This article is a reflection on how chART took advantage of this assembly, creating an ambitious venture aiming for a sustainable effect on the public’s relationship to urban birds. As the Crow Flies was a public art project bringing creative connections to urban birds directly into the hands of the public. Works included sited-sculpture, community-engaged interventions, projections, workshops, performances, and 6,000 ceramic crows.

chART’s founder, Cameron Cartiere has been working with an interdisciplinary team to address the loss of pollinators through Border Free Bees. That research project used environment-based art to engage communities to take positive action in order to improve conditions for pollinators, with tremendous success. As the Crow Flies took a similar approach to highlight the loss of bird species and actions individuals could take to improve the odds for their feathered neighbours.
Play as a Player in Design. Rethinking a ‘Curious Practice’ for Co-designing Public Space
Authors: Winge Laura , Wagner Anne Margrethe , Lamm Bettina
Published: September 2021

‘Move the Neighbourhood’ is a research project experimenting with co-designing playable installations for a public green space in Copenhagen through a design-based collaboration between children and design-researchers.
We employed a co-design process to investigate whether deconstructing the rules for both play and design could trigger new ways of thinking about playable spaces. The aim was to test a participatory process in order to identify what might be meaningful in relation to both play and designing for play, along a spectrum ranging from rules to collaborative improvisation. Our fieldwork cultivated what Haraway calls ‘response-ability’ in a ‘curious practice’ that explores the unanticipated in the collaboration between children and designers.
The metaphor of a ‘jelly cake’ from play-research was used to illustrate the messiness of play and to frame the discussion on collaborative design. We see play as a serious co-player that evokes collective worlds through productive, messy fields of action, and enables actors to engage in the co-design of playable public space.
In this article, we investigate how play can create agency, spark imagination and open up practices in both artistic and academic processes. Drawing on Barad’s concept of ‘intra-action’, we investigate design/play as a dynamic engine for exploring collaborative design practices as a dialogue between art, play and co-design.
六/6: Finding Meaning. The Expanded Exhibition and the Post-Pandemic World
Authors: Baldini Andrea Lorenzo
Published: September 2021

How will artistic exhibitions function in the post-pandemic world? Visiting museums and galleries is a health hazard. 六/6: Finding Meaning is an attempt to offer an alternative. It embodies a novel exhibiting format called the expanded exhibition, which inhabits an expanded public space, between the physical and the digital. 六/6shows us that, once liberated spatially, exhibitions can be effective tools of meaning-making and social change even in a post-pandemic world. By exploiting the interplay between the digital and the physical domains, expanded exhibitions such as 六/6 can build alternatives of cultural production that can cope with social distancing, while being participatory, democratic with respect to access, and politically transformative by displacing the colonialist hierarchy center/periphery.
Artistic Acupuncture Missions. Penetrating the Public Space
Authors: Bashiron Mendolicchio Herman
Published: September 2021

9 places in Europe, 9 artists and collectives, 9 hosts (European Festivals of Art in Public Space) and one multi-layered artistic framework and methodology –the acupuncture– to respond to specific challenges related to urban renewal, social justice or cultural identities. The IN SITU Network has developed this ambitious project in collaboration with its partners between autumn 2018 and the end of 2019. The artists have explored different territories and got to know their specific challenges by engaging in conversation with a wide range of stakeholders. After a short residency period the artists come up with their imaginative proposals, based on a fresh look and inquiry. Built on the analysis of the 9 artistic acupuncture missions, this portfolio aims at focusing on the innovative methodology and strategies employed by the artists in different and complex contexts. The text explores how the artists, in collaboration with their hosts, have developed their creative missions and interpreted the changing meanings, values and functions of public space.
