Authors: Setyowati Erni , Indriastjario  , Astetika Sara Isti 
Published: February 2020

Abstract
Known as the Rainbow Kampong, the kampong Wonosari is a kampong in the Randusari sub-district, a district within a region of the South Semarang District. Previously known as a slum kampong, people have named the kampong to become the Rainbow kampong due to the thematic kampong program which was accelerated by the Major of Semarang city in 2016. The kampong has two RW (Rukun Warga) with a population of more than 3,000 inhabitants. Based on the population data of Randusari sub-district, the RW #3 of the Kampong Wonosari has 1,724 inhabitants divided into 10 RTs (Neighborhood Groups). With this high level of population density the existence of communal space is very important. Refer to the number of households and the low carbon concept, the kampong could reduce the carbon dioxide emission as much as 21.3689% by re-designing the communal spaces.

Published: February 2020

Abstract
Recent efforts of restoration on the Muslim religious sites in Jakarta take place in several old mosques that were built around the old settlements (kampung) of creole communities in Pekojan. This historic kampung is situated on the western fringe of Jakarta Old Town since eighteenth century and adjacent to the other diverse ethnic groups’ neighbourhood. The challenges emerge when the old mosque continues to expand its space volumes and adapt to accommodate the users’ needs and so the expansion impacts the ethics of restoration. This research specifically took a case study in Jami Mosque of Kampung Baru as one of the heritage mosques built in Pekojan. The early process of the documentation and historical research found various levels of deteriorations and extensions in the building. By applying participatory action research, it showed the early efforts of restoration led by locals. This research also concerned with the responsibility of the owners, functionaries, community officials, and users towards the cultural heritage to be contested. It also extended the conceptual meaning of “ownership” of cultural heritage by definition in terms of religious building in Indonesia.

Abstract
Bidadari Island is one of the tourism area, located in the southern part of Kepulauan Seribu. Tourism activities and its location that directly facing Jakarta Bay, obviously will affect the quality of the waters and ecosystems in Bidadari Island. A study of benthic foraminifera was carried out in 10 surface sediments and water quality samples, collected from the Bidadari Island, in order to determine the connection between abudance of foraminifera with the environmental conditions. Quantitative analysis, including calculation of abundance, community structure, and biplot analysis conducted to obtain this information. The results showed that there were 2473 individuals benthic foraminifera with a total of 33 species from 23 genera. The most abundant genera were Amphistegina, Calcarina, and Operculina. Based on the calculation of the community structure (diversity, evenness, and dominance index), benthic foraminifera on Bidadari island are in the low to moderate category, it indicating that the environmental condition in this area has begun to declined.
Effects of Six Types of Straw Derived Biochar on Anaerobic Biodegradation of Polybrominated Diphenyl Ethers in Mangrove Sediments: A Microcosm Experiment

Published: February 2020

Abstract
Biochar has widely applied as sorbent for sequestrating pollutants, however, its effects on biodegradation of organic pollutants and microbial mechanisms behind remains poorly understood. Here, we carried out a microcosm experiment to investigate the effects of six types of straw derived biochar on anaerobic biodegradation of polybrominated diphenyl ethers (PBDEs) in mangrove sediments. The results showed that the reductive debromination was a critical process of PBDE degradation under anaerobic condition. The reductive debromination efficiency was significantly enhanced after the addition of rice straw and corn straw biochar prepared at relatively low temperatures (C300, C400 and R300), but was inhibited by rice straw biochar produced at high temperatures (R500), indicating that the biochar effects on PBDE degradation depended on its pyrolysis temperature and straw type. The stimulatory effects of C300, C400 and R300 may be attributed to the increased abundance of organohaliderespiring bacteria (OHRB), especially genera Dehalogenimonas, and the high diversity of typical OHRB in family Dehalococcoidaceae. In addition, biochar addition significantly altered the bacterial community compositions, in particular, several OHRB genera were enriched by C300, C400 and R300, facilitating the anaerobic biodegradation of BDE-47 in contaminated sediments. These results will help us to understand the potential of biochar amendment for contaminated remediation.

Published: February 2020

Abstract
In this paper, a new type of indoor air purification device was designed. Corona discharge combined with catalysis and physical adsorption was used in this device. Formaldehyde (PA), a typical indoor air pollutant, was chosen as the model pollutant. The effects of MnO2 in degradation of PA by electrical discharge were discussed. The results showed that corona discharge can effectively remove PA, and the addition of MnO2 can not only accelerate the degradation rate, but also solve the problem of excessive ozone (O3). Besides, the corona discharge plasma also has the function of in-situ cleaning for MnO2. The new reactor has the characteristics of high efficiency, energy-saving, without secondary pollution.

Published: February 2020

Abstract
In this paper, the removal performance of Triamcinolone acetonide (TA) by ClO2, NaClO, O3, K2FeO4, and KMnO4 oxidation was assessed. The effects of pH value and humic acid (HA) on TA removal during KMnO4 oxidation process were also investigated. The results showed that ClO2, NaClO, and O3 were not sufficient for TA elinimation. However, K2FeO4 can capable of removing TA effectively, and the removal rate of TA can be achieved 84.6% at 60 min while K2FeO4 dosing at 10 mg/L. However, the removal effect of TA in water was inhibited as the concentration of K2FeO4 overdosed. KMnO4 can degradate TA effectivly. TA can be completely removed after 90 minutes while the initial concentration of TA is 250μg/L and the KMnO4 dosage at 50mg/L.Weakly acidic and neutral conditions can promote TA removal, the effect of Humid acid (HA) on TA removal was based on the HA dosage, an inhibitory effect was obsearved when the dosage of HA from 1mg/L to 5mg/L, however when CHA≥7mg/L, HA can accelerate TA removal.

Published: February 2020

Abstract
Incorporating uncertainty assessment into hydrological simulation is of vital significance for providing valuable information for conserving and restoring the ecology environment in arid and semiarid regions. In this study, a sparse polynomial chaos expansions method was developed to quantify hydrological model parameter uncertainties on model performance in Kaidu river basin, China. A four dimension two order polynomial chaos expansions model was built and the effect of four parameters were quantified based on the coefficients of the polynomial chaos expansions model. Results indicated that precipitation in summer has more significant influence on model output than that in other seasons. High Sobol sensitivity indices values (0.22 in spring, 0.17 in summer, 0.21 in autumn and 0.29) for the interaction of precipitation and maximum capacity for fast store demonstrate that they are the major factors affecting runoff generation. These results can help reveal the flow processes and provide valuable information for water resources management.

Published: February 2020

Abstract
In this study, a Water-footprint Assessment Method (WAM) is proposed to assess agricultural water footprint and its flow in Uzbekistan’s agricultural sector. Several findings can be summarized: (i) the annual average water footprint of the agricultural sector is 33.3 billion cubic meters, which is in a downward trend, the main reason is the reduction of crop yield and the improvement of water use efficiency; (ii) the Green Water Footprint (GWF) and Blue Water Footprint (BWF) are 133 and 20 billion cubic meters respectively, cotton contributed most of the BWF, indicating that cotton consumed a lot of surface and groundwater, which indirectly led to the shrinking of the Aral Sea; (iii) an annual average of 3.23 billion m3 of total water footprint (TWF) flows to neighbouring countries such as Russia Federation, China and Bangladesh through agricultural products, accounting for 6.6% of the total water resources of Uzbekistan. These findings will provide theoretical and data support to policy makers for water resources optimization management.

Microbiota as an indicator of the environmental burden of mined-out sites
Authors: Boturova K 
Published: February 2020

Abstract
The article focuses on the characteristics of the microbial community in the postmining territory of Poproč (Slovak Republic), where polymetallic ore was mined in the past. The investigated waste substrates are characterized by the still high presence of antimony, arsenate, lead and other toxic and potentially toxic metals and semimetals. Microbial activity in postmining substrates was established on the basis of the presence of functional microbial biomass by fumigation-extraction method. The results are complemented by additional ecosystem parameters, in particular, the representation of individual cultivable groups of microorganisms. The activity of the microbial community is in direct interaction with the post-mining environmental burden and can, therefore, be considered as an indicator of the revitalization of the in situ environment.

Main parameters of a wastewater treatment plant up to 2000 PE in the Czech Republic
Authors: Hlustik P 
Published: February 2020

Abstract
The article deals with optimising the design parameters of wastewater production and specific pollution production in wastewater treatment plants up to 2,000 PE. The values of design parameters for the WWTP calculation are laid down in the legislation (ČSN 75 6401 and ČSN 75 6402) recommending their use with a potential reduction in the pollution of up to 50% according to the size of the municipality. Determination of the pollution reduction is no longer defined in standards and design values for different drainage systems are not defined, either. The design values for WWTP calculations should be based on realistic measurements covering at least the past three years. The objective of this article is to determine more precise design values applicable to WWTP calculations and different drainage systems on the basis of statistical evaluation of individual water quality indicator analyses.
Dishwashing detergents and their effects on respiration inhibition of activated sludge
Authors: Klimantova V , Raclavska H , Bouchalova J 
Published: February 2020

Abstract
Nowadays, many households in the Czech Republic have a dishwasher. Their use releases the remnants of the dishwashing detergents used therein into the sewerage network. These substances affect the activity and also the lifetime of microorganisms in wastewater treatment plants (WWTP). Research is focused on respiration inhibition of microorganisms contained in activation sludge from WWTP and their affected by dishwashing detergents. In view of Regulation No 259/2012 of the European Parliament and of the Council concerning the limitation of the total phosphorus content of dishwashing detergents (into force on 1 January 2017), there have been significant changes in the structure of these detergents. The article describes the effect of selected dishwashing detergents on respiratory inhibition of activation sludge from a large municipal WWTP Ostrava and a small municipal WWTP Michálkovice. Both of these WWTPs are owned by OVAK (Ostrava waterworks and sewerage). Subsequently, the research is focused on the comparison of obtained results. The highest variation in values were measured for sample 3, where the inhibition measured when testing a sludge from a large WWTP differed by up to 60% from that measured when testing a sludge from a small WWTP. The research also evaluates possible causes of respiration inhibition of microorganisms when testing specific sample solution.

Authors: Singrova V , Hlustik P 
Published: February 2020

Abstract
The aim of this article is to describe and compare individual laws concerning wastewater discharges and their monitored indicators. Relevant laws and government regulations have been in existence since 1953, when the Central Administration of Water Management was established, with the latest regulation being Government Decree No. 401/2015 Sb. This article deals with the development of legislation, its amendments and improvements. This results in a gradual adjustment of the monitored indicators and decreasing indicator values in connection with improving treatment processes and technologies. This is also related to the Czech Republic’s accession to the EU and the adoption of Council Directive 91/271/EEC, which emphasises, inter alia, environmental protection.

Authors: Zaoralova Z , Kupka J , Stalmachova B 
Published: February 2020

Abstract
This paper explores whether orthopteran insects (Orhtoptera) may be used to study bioaccumulation of potentially toxic elements in their bodies on the territory of Ostrava City. For the purpose of laboratory analysis, we used a common species Metrioptera roeselii (Ensifera) and Chorthippus parallelus (Caelifera). The laboratory analysis confirmed a bioaccumulation of some potentially toxic elements (Ni, Zn, Cu, Cr), which is probably dependent on the distance of the sources of pollution and main wind direction.
Rheological Characteristics of Reclaimed Asphalt Pavement (RAP) Evaluation using Reclamite Rejuvenating Material
Authors: Twidi Bethary Rindu , Sugeng Subagio Bambang 
Published: February 2020

Abstract
Using reclaimed asphalt pavement (RAP) does not only reduce costs but is also environmentally friendly. In its use, it is very important to know the empirical and rheological properties of the asphalt. The testing in this study used a Dynamic Shear Rheometer (DSR) to test asphalt pen 60/70, RAP and Reclamite rejuvenating material mixed with RAP. The results of the pen asphalt 60/70 empirical test met the Bina Marga 2010 General Specifications of Roads and Bridges, while the RAP showed the characteristics of an aging asphalt. In the rheological test based on SUPERPAVE, from the value of the performance grade (PG), it was found that Reclamite reduced the critical temperature value on RAP, so the PG value was the same as the asphalt pen 60/70. The master curve results also showed that Reclamite can reduce the RAP stiffness modulus near the value of asphalt pen 60/70 stiffness modulus. Meanwhile, as seen from the results of the black diagram, the original condition has a range of phase angle (δ) greater than the RTFOT and PAVT conditions because the asphalt has undergone aging. At the same Sbit, asphalt pen 60/70 has a greater (δ) than RAP, while for RAP added with Reclamite, the value is between the RAP and asphalt pen 60/70 value. This illustrates that the Reclamite rejuvenating material makes RAP more viscous.
