Published: October 2022

Abstract
The development of broiler chicken farm business is not only able to meet the community need for protein, but also causes disturbance to the surrounding environment, especially when it is closely located to residential areas. Business waste can be in the form of physical waste such as wastewater and the presence of flies, as well as social waste in the form of unpleasant odors. This study was aimed to determine the willingness to pay (WTP) of chicken owners for the impact of the waste produced, willingness of the community around the farm to accept compensation (WTA) for the impacts received, the percentage of environmental costs to the total cost structure and the factors that affect the value of willingness to accept compensation. The data analysis used is the Contingent Valuation Method with a bidding game question system and multiple linear regression analysis. The results showed that mean WTP value from farm owners for physical waste was Rp. 3.103.300,-/owner/production period and for social waste was Rp. 280,000,-/head of family/production period. Moreover, the mean WTA value of the community was Rp. 271,866,74,-/head of family/production period. Factors that affected the WTA value included education, income, knowledge, and number of family members.

Abstract
Because pregnant women must frequent health institutions to monitor their pregnancy, they are more prone to catching COVID 19. As a result, adherence to pregnant women’s behavior in preventing COVID 19 is critical. The elements that influence pregnant women’s behavior in terms of COVID 19 prevention are examined in this study. This research is a cross-sectional descriptive analytic non-experimental study. The incidental sampling approach was used to collect samples (n=102). The Chi square test and logistic regression were used to evaluate the data. The findings revealed that COVID 19 preventative behavior was influenced by knowledge, attitudes, fear of COVID 19, and belief in COVID 19 information. Following the completion of the logistic regression test, COVID 19 knowledge was found to be the most influential variable in COVID 19 preventative behavior (p = 0.000). When compared to those with good information, those with less understanding have a 16,101 times higher risk of misbehaving in preventing COVID 19 (Exp(B) 16,101).

Published: October 2022

Abstract
Most districts/cities in Central Java Province fall into the category of high-level disaster areas especially extreme weather hazards. Increasing regional/city resilience and reducing disaster risk have become policies both at the central government level and at the regional (district/city) level. Disaster risk according to ex-ante and restrictive interpretations, is the result of the interaction between the hazards of a natural event and the elements exposed to hazards and their vulnerabilities. Potential areas of extreme weather hazards (hazard level = H) in the Central Java Province, which covers 35 cities/districts; some areas have high hazard level. The potential population exposed to extreme weather (vulnerability level = V); most areas have high level. The potential for extreme weather losses (exposure level = E) all regions have high level. Given that vulnerability (V) in the Central Java Province is dominated by many poor people, the strategy that needs to be done to reduce vulnerability is through poverty alleviation programs. To reduce the level of exposure (E) in the form of large physical and economic losses, it is necessary to provide the urban infrastructure that ensures the sustainability of the social-economic activity system can take place properly. In addition, to overcome environmental damage, it is necessary to carry out an environmental conservation program in the Central Java Province comprehensively and sustainably.

Published: October 2022

Abstract
The objective of this study is to discover and discuss the legal management of natural resources in the Indonesian coastal region using preventive monitoring and licensing tools. The employed method is a normative method with a conceptual and legislative approach. Preventive instruments in controlling pollution and environmental damage in coastal areas need to be implemented using supervision instruments and business permits. The relevant agencies under their respective authorities supervise the coastal regions and small islands in a coordinated manner. Local communities and traditional communities can also carry out control. Everyone who uses coasts and tiny islands, partly and permanently, must have a business permit. Communities governed by customary law are excluded from obtaining business permits for the use of space in coastal and marine zones. Therefore, beginning with the process of planning, usage, supervision, and control in coastal regions and tiny islands, society must be actively involved.

Abstract
Banten Bay coastal waters continuously receive waste input from anthropogenic activities including heavy metal concentrations, which it has increased and caused accumulation in aquatic biota such as green mussels (Perna viridis) that live in the waters. This study aims to determine the accumulation level of heavy metals Hg, Cd, Pb, and Cu in the green mussels in Banten bay of Bojonegara. Sampling of the green mussel and water quality observation were conducted in the bay for three months from August to October 2020. Analysis of the heavy metals content was conducted using Atomic Absorption Spectrophotometer (AAS) method. Water quality parameters observed in-situ and ex-situ were temperature, transparency, turbidity, TSS, pH, salinity, and DO. Bojonegara coastal water quality was in accordance to the standard quality value. Heavy metals Hg, Cd, Pb, and Cu in the waters were below the quality standards. Heavy metal bioaccumulation Cu in the green mussels in medium to high category, while heavy metals bioaccumulation Hg, Cd, and Pb were in low category. The safety limit for consumption of the green mussels for children (15 kg) was 5.91 kg of meat/week, while for adults (50 kg) was 19.69 kg of meat/week.

Published: October 2022

Abstract
Sphagnum mosses play a significant role in the plant communities of the south-belomorian bogs. The adaptation of these plants to environmental conditions can be traced through changes in the pigment complex. In this work, the content of chlorophylls a and b and carotenoids was determined in some ridge species (Sphagnum fuscum, S. rubellum) and hollow species (S. lindbergii and S. majus) in June and September. An increase in total pigments in species growing on ridges is observed in autumn and that can be explained by the formation of comfortable conditions for photosynthesis. The growth of algal biomass can cause a decrease in the pigment content in the species of hollows.
Diversity of herb-Sphagnum rich-fen communities in north European Russia
Authors: Kuznetsov O L 
Published: October 2022

Abstract
Seven associations of herb-Sphagnum rich-fen communities were identified in the north of European Russia. The identification was done by the topological-ecological method based on dominant species and eco-coenotic groups of species. The associations differ in scope from Northern and Central European syntaxa. East Fennoscandian syntaxa should be construed as Fennoscandian races of associations with wider distribution ranges. A classification of North Eurasian herb-Sphagnum rich-fen communities needs to be developed using a common methodology.

Published: October 2022

Abstract
The paper presents a new paleoecological evidence covering the last 6500 years based on detailed AMS radiocarbon dating, plant macrofossils, loss on ignition and macroscopic charcoal records from a 8 m long peat sequence, obtained from the palsa mire situated near Igarka (Yenisei Siberia). The obtained data show that the peatland initiation, development of the perennial frost mound and local vegetation history were strongly influenced by the Holocene climatic fluctuations and permafrost dynamics. The main stages of palsa uplift occurred at about 5360 cal yr BP and 2250 cal yr BP and coincided with the periods of cooling in the Russian Arctic region. According to the radiocarbon dating and plant macrofossil analysis of the upper part of peat sequences the peat accumulation rate in the palsa decreased significantly during the last 2000 years. Nevertheless, we consider that the rate of the peat vertical growth could be underestimated due to the disturbance of the frost mound, water erosion and wildfires.
Short-term design of geosynthetic-reinforced embankments on soft foundation soils
Authors: Romeo D , Pezzano P , Rimoldi P 
Published: October 2022

Abstract
The stability of an embankment on soft foundation soil is most critical during the construction period, because of the relatively low permeability of the soft foundation. Since the stability increases as the foundation consolidates, related design is controlled by short-term constraints. Geosynthetics for basal reinforcement enhance the stability of an embankment over soft soil by preventing lateral sliding of the fill, extrusion of the foundation and rotational failure. The stabilizing force developed by the reinforcement is generated by shear stresses mobilized along both the interface surfaces of the reinforcement, with the foundation soil and the embankment fill respectively. In fact, the reinforcement has the double function of carrying the outward shear stresses transmitted by the embankment fill and of providing inward shear stresses to restrain the foundation soil from lateral squeezing-out. For each of the limit states mentioned above, the associated reinforcement strength and bond length should be checked to ensure that the limit state tensile load can be generated in the reinforcement. Starting from considerations proposed by the British Standard 8006:2010, this paper focuses on lateral sliding and foundation extrusion limit states by presenting a design method to evaluate the reinforcement strength and bond length required to provide the maximum improvement for an embankment on soft soil.
Reduction of carbon footprint of roads construction thanks to the Pavement Optimisation with hexagonal geogrids
Authors: Mazurowski P 
Published: October 2022

Abstract
There is a growing demand on reduction of greenhouse gases emission from all branches of industry. Roads construction is responsible for a substantial part of building industry carbon footprint. One of the ways to reduce its carbon footprint is the use of Pavement Optimisation (PO) with hexagonal geogrids technology. This technology utilizes the phenomenon of aggregate stabilisation by interlock within apertures of geogrid. When aggregate is placed and compacted on a layer of geogrid, a geogrid/aggregate composite – called Mechanically Stabilised Layer (MSL) - is created. Stiff geogrid ribs resist particle movement reducing layer deformation, which increases its stiffness. Increased stiffness of aggregate can be utilized in design, and has a substantial influence on pavement life. This provides the possibility to reduce the thickness of a pavement, including thickness of asphalt. Thinner pavement will require less materials, workforce, time and energy. It will be cheaper, and its construction will result in lesser emission of CO2. This paper presents the overview of Pavement Optimisation technology and results of full scale accelerated pavement tests confirming the influence of hexagonal geogrids. Case studies of projects with optimised pavements and calculations of carbon footprint savings achieved thanks to the use of PO are presented.

Published: October 2022

Abstract
The results of drained triaxial compression tests and DEM simulations of sand-rubber mixtures presented in the literature were analysed using of frictional state concept. The stress-plastic dilatancy relationship at different shear stages can be approximated by straight lines determined by critical state angle and two parameters of the frictional state concept. The points representing failure state lie on the frictional state line as for pure sand without rubber. The frictional state concept can be used to simply describe the stress-dilatancy relationship of various sand-rubber mixtures.
Investigation of force transmission during indirect activation of a geogrid in transparent soil
Authors: Derksen J , Ziegler M 
Published: October 2022

AbstractThe composite material geogrid reinforced soil has a wide range of applications. In most cases the geogrid reinforcement is indirectly activated by an applied load via the surrounding soil, for example in base layers of embankments, foundation pads and fill structures. Within these geogrid reinforced structures, different areas can occur in which the direction of force transmission might differ from soil to geogrid and vice versa. In particular, the force transmission in the soil-geogrid-interface involves a fundamental need for research. Therefore, this paper firstly introduces a conceptional model for indirect geogrid activation, secondly presents a test rig in which the interaction mechanisms can be investigated on micro scale and thirdly determines various areas with different directions of force transmission. For this purpose, transparent geogrid reinforced specimens are biaxially loaded, whereby an area-wide and undisturbed insight into the soil-geogrid-interface is enabled. The transparent soil is created as a two-phase medium consisting of a crushed fused quartz and a white oil with a corresponding refractive index. The displacement fields of the geogrid and the surrounding transparent soil were determined using a digital image correlation (DIC) method based on images taken continuously during the test. Then, strain profiles were derived for the longitudinal tensile members, which were converted into a force distribution along the geogrid. As a result, the conceptional model can be verified.

Published: October 2022

Abstract
The focus of this paper is on providing an overview of the results of the nearly 20 years of research related to the discovery, examination, and potential benefits of semipermeable membrane behavior of bentonite-based geosynthetic clay liners (GCLs) commonly used as barriers or components of barriers in a variety of hydraulic and chemical containment applications, such as water and chemical retention ponds, tailings and coal ash impoundments, and solid waste landfills. First, the concept of solute restriction underlying semipermeable membrane behavior and the development of a solute-restriction or membrane efficiency coefficient (ω) and chemico-osmosis (q
π) are described. Second, previously measured values of ω are presented for clays and GCLs for the purpose of illustrating the physical and chemical factors affecting ω. Third, the potential benefits of both ω and q
π in terms of hydraulic and chemical containment applications are illustrated, and the relative importance of ω versus q
π is described. Finally, some of the remaining issues related to the semipermeable membrane behavior of GCLs, such as the uniqueness of the measured ω and the persistence of ω at high salt concentrations, are discussed.
