A Python based automated tracking routine for myosin II filaments
Authors: Mosby L S , Polin M , Köster D V 
Published: April 2020

Abstract
The study of motor protein dynamics within cytoskeletal networks is of high interest to physicists and biologists to understand how the dynamics and properties of individual motors lead to cooperative effects and control of overall network behaviour. Here, we report a method to detect and track muscle myosin II filaments within an actin network tethered to supported lipid bilayers. Based on the characteristic shape of myosin II filaments, this automated tracking routine allowed us to follow the position and orientation of myosin II filaments over time, and to reliably classify their dynamics into segments of diffusive and processive motion based on the analysis of displacements and angular changes between time steps. This automated, high throughput method will allow scientists to efficiently analyse motor dynamics in different conditions, and will grant access to more detailed information than provided by common tracking methods, without any need for time consuming manual tracking or generation of kymographs.

Published: April 2020

Abstract
We study the phase diagrams for the Potts model with competing binary, ternary and quaternary interactions on Cayley tree of order 2. At vanishing temperature T, the phase diagram is fully determined for all values of competing binary, ternary and quaternary interactions. We extend the results (for the case Jq
= 0) obtained by Ganikhodjaev et. al. [9]. The results show that the appearance of addition phases: antiferromagnetic and Period 6, in the case of nonzero quaternary interactions for several ranges. Then, we investigate the modulated phase, with the phase being indicated by many different types of commensurate and incommensurate phases by plotting the wavevectors versus temperature. Lastly, the Lyapunov exponent is used to verify the stability of the periods.

Application of electron accelerator for flue gas treatment of coal power plant to support green technology
Authors: Darsono  
Published: April 2020

Abstract
Fossil fuels, which include coal, natural gas, petroleum, shale oil, and bitumen, are the main source of heat and electrical energy, but burning these fuels will emit pollutants to the environment. Most countries use coal burning power plant in generating electricity for living needs such as household electricity and industrial development. This power plant generates large quantities of pollutants (SOX and NOX) that create acid rain and smog leading to the water and soil degradation and they can affect living things. To meet rising worldwide energy demand, projections call for the use of coal to increase by 50 percent from 2006 - 2030, as a consequence SOX and NOX pollutions will rise. There are two conventional technologies to decrease air pollution from coal power plant, the first is FGD (flue gas desulfurization) based on SO2 absorption in lime or limestone slurry; and the second is SCR (selective catalytic reduction) based on NOx reduction over a catalyst to atmospheric nitrogen with ammonia as a reductant. But these technologies cannot treat different pollutants in one step process. To support green technology program, this paper describes a modern technology called EBFGT (electron beam flue gas treatment) which can treat SOx and NOx in one step process using electron accelerator. The technology and economy comparison between FGD, SCR, EBFGT as well as the existing EBFGT in the world are compiled.

Published: April 2020

AbstractSilica gel was synthesized from Lapindo mud by the sol-gel process. XRF analysis confirmed that Lapindo mud contained silica (50%) which was major components, therefore Lapindo mud has great potential as a raw material for silica gel synthesis. Metal silicates commonly used as a precursor to prepare silica gel. A Lapindo mud was mixed with an alkaline solution, stirred and heated to prepare metal silicates. Hydrochloric acid was then slowly added to the metal silicates solution to obtain silica gel. The pH 4 selected as the optimum pH in the synthesis of silica gel. The purity of synthesized silica was determined by XRF and shown that silica purity by 100 mL sodium hydroxide 6 M (4 h, 80 °C) treatment was 63.25% with optimum yielded 32.3%. Whereas 12 M potassium hydroxide 200 mL (5 h, 90 °C) treatment could be produced better purity up to 77.71% with a yield of 39.72%.

Published: April 2020

Abstract
Purple-fleshed sweet potato with high anthocyanins is beneficial to health due to its antioxidant activity. Therefore, 13 promising genotypes of purple-fleshed sweet potato and two improved varieties as checks (Antin 2 and Antin 3) were studied their physical, chemical and sensorial characteristics. The results showed that the flesh colors ranged from red-purple, deep purple to white purplish and their lightness values (L*) negatively correlated with anthocyanin contents (R
2 = 0.65). Six promising genotypes contained anthocyanins >100 mg/100 fw with the highest value observed in RIS 10051-01 (155.47 mg/100 g fw) that was similar to Antin 2. Antin 3 showed the highest content of anthocyanins among all genotypes (177.48 g/100 g fw). MSU 10002-05 and MSU 10010-43 genotypes had higher dry matter contents (33.43% and 37.85%) than Antin 2 and Antin 3, suggesting their promising use for flour processing. High anthocyanins is normally associated with a bitter taste, however the steamed tubers of two deep purple genotypes, namely MSU 10010-43 and Antin 3 and one white purplish genotype (MSU 1000115) were fairly liked for their color, texture and taste attributes, hence they are tailored for steamed food purposes. This information supports the breeder to release a new variety of purple- fleshed sweet potatoes.

Published: April 2020

Abstract
The relation between cell and turbidity (cloudiness) in suspended form is studied intensively to facilitate the estimation of the cell number. A standard curve in turbidimetry has utility to compare the turbidity reading value for the determination of Saccharomyces cerevisiae cell number and using a model. A standard curve is a prospect in this issue for the cell that has an inherent inaccuracy in the method as well as spectrophotometry. This research is conducted to obtain a model for the standard curve using analysis and diagnosis of the linear regression which was measured the relative standard error (SE) value of the dependent variable by simulation of turbidity value and verification of the applied model. We obtained the smallest relative SE from one of the five datasets that resulted in less than 10% of the relative SE on the estimated cell number. Plotting all of the bivariate data resulted in a larger error on the scattered light intensity at the higher cell number value, and this characteristic was named heteroscedasticity. Application of turbidity method for cell enumeration per mL in the media was significant equal and lower coefficient variation than the result of verification by a viable method.

Published: April 2020

Abstract
The aims of this study were to know flowering and fruiting pattern of the four Cinnamomum and their response in relation to seasonal change in rainfall, temperature and air humidity in Purwodadi Botanic Garden. The vegetative and reproductive activities were observed once per week based on the abundance of leaves, flowers and fruits using a scoring method from 0-4, for 6-8 years of observations. The rainfall per month, temperature, and humidity were simultaneously recorded. Data were analysed by Principal Component Analyses to determine the microclimate variables that have correlation to the reproductive activity patterns of all four species. Most species started flower budding during Juni – August, except C. burmanii which produced flowers 2-3 times per year in small quantity. Flowering of C. burmanii showed positively correlations with rainfall intensity, while flowering the other three species did not relate to microclimate in PBG. Six dry months preceding a long dry season in 2015 caused C. burmanii did not produce flowers and fruits.

Authors: Yakin K , Rusmana N I , Setyaningsih I , Tirono M 
Published: April 2020

Abstract
The getting older of people age, the density of bone will be further reduced. The process speed of bone formation decreases progressively after reaching peak bone mass in the age range 25-30 years. The reduction in bone density is known as osteoporosis. This phenomenon occurs due to an interruption on remodelling bone due to some conditions. Therefore, this study is going to simulate the effect of mechanical stimuli on femur bone density using walking and standing mechanical stimuli. In this study, there are four stages passed. First, build the femur bone construction which consists of two layers (cortical and trabecular). Then input the properties of bone based on age (Young’s modulus and Poisson’s ratio). Then calculate the stress, strain and strain rate and calculate the bone density using thermodynamic equation of V. Klika and F. Marsik with Runge-Kutta method of 4th orde. The bone density given standing mechanical stimuli (1290 N) for age 25 is 0.7963 g/cm2 and walking mechanical stimuli (1741.5 N) is 1.0698 g/cm2. Then the bone density given standing mechanical stimuli (1200 N) for age 51 is 0.7703 g/cm2 and walking mechanical stimuli (1620 N) is 0.9885 g/cm2.

Published: April 2020

Abstract
Nowadays, environmental problems are important issues that require people to respond in the right ways to prevent worse disasters. For that reason, environmental literacy discourse is an important issue to be built informal and non-formal education and in the public sphere. Environmentally literate individuals have the knowledge and skills required to analyze the environmental problems so that they can behave pro-environmentally. This paper has a purpose to know how the local young people in Trenggalek (a rural district in the southern coastal area of East Java) develop environmental literacy through a local portal of “Nggalek.co.” The Trenggalek-based portal “Nggalek.co” is intended as the means for communicating their localities to their community and the world. This paper will explore the environmental literacy discourse presented in the portal by using Critical Discourse Analysis by Fairclough. This analysis applied three levels of analysis, micro, meso, and macro. The study shows that environmental literacy is a somehow essential issue in this portal, especially when it is related to governmental policy in environmental problems. The awareness of the environmental problems shows a high level, especially because it is directly related to people’s daily life, that is when there is “natural” disaster people got direct impact.

Authors: Hutagalung J M , Tobing C I , Debastri J , Amanda R T 
Published: April 2020

AbstractNon-operational satellites and other space junk, including jettisoned spent rocket stages, old satellites and other space objects, are creating a huge stock of garbage in outer space. Space debris environment poses a damage risk to spacecraft in Earth orbit and also poses the risk of damage on the ground if debris survives Earth’s atmospheric re-entry. From the early 1960s, Indonesia has promptly begun to perform space activities. From rocket research and development in 1970, programs related to space science and technology in 1980, and currently Indonesia operates its own 6 satellites (5 in GSO and 1 in LEO). Indonesia has ratified Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, 1967 (Outer Space Treaty) with the Law Number 16/2002 and also enacted Law Number 21/2013 on Space Activities. However, the lack of regulation regarding on environmental protection aspect on outer space should highlight Indonesian law system as the development of space technology threaten the territory also. This writing aims to study the space debris and environmental protection on the national level and utilized that as a means on space environmental sustainability in Indonesia.

Abstract
The progress of a country is marked by the rapid development. The impact will require a lot of land to support development. Lately there has been a widespread process of releasing forest land for the benefit of the company as one of the sectors supporting economic development. Making this need to be further investigated in terms of the benefit of nature and humanity for the survival of human life in the future. Environmental fiqh as an idea which regulates how humans are able to synergize with nature appropriately in accordance with Islamic laws and certainly will not neglect the interests of the State. So that by using this approach development will not be hampered, but also can be realized. This study uses the method of literature by analyzing using the fiqh and usul ulh fiqh principles which strengthen the argument about the importance of the environmental Jurisprudence approach to achieving maslahat-based development.
