Published: November 2019

Abstract
The scarcity of land and the lack of communal sanitation in slum areas are common issues in densely populated country like Indonesia. One of them happens in Kampung Nambo, located in South Tangerang City, Banten Province. Those issues encourage some household to build their houses without an adequate sewage disposal system within a very limited land. Wastewater flows directly to the river without any treatment process and it creates negative impact to the environment and human life. Moreover, this kampung also does not have educational and recreational parks facilities, which can fulfil human’s need to socialize and health. The method used in this study is an action-based research. Addressing the problem of scarcity of land and the need for WWTP facilities, the complementary facilities offered are hydroponic farming, workshop venue, playgrounds, reading park, sports facilities that are integrated with the proposed WWTP area. Generally, the WWTP areas often placed in the backside and were not utilized optimally. Meanwhile this study accommodates the WWTP towards integrated and multifunction facility. It is not only to fulfil the needs of education and recreation parks for the community, but also to preserve the location for WWTP extension in the future.

Abstract
The main idea of this research is to investigate the bending strength improvement of patching repair method on partially decayed wood beam. The patching method was carried out by removing the decayed part of the beam and covering the void left by a small piece of identical wood. Epoxy resin with 30 MDGL glue spread and 1 MPa cold pressing was used to stick the small piece of identical wood into the void. Four-point loading method then applied on Jati (Tectona grandis) wood beam specimens that have cross sectional dimension of 60 mm by 80 mm and 1200 mm length. Patching method were applied on two types of beams; the tension and compression side repair of the beam. The experimental result showed that both types of the repair could improve the bending strength of the partially decayed beam. However, the tension side repair was not able to restore the bending strength as the compression side repair beam specimen.

Published: November 2019

Abstract
Domestic wastewater contributes about 40% as the source of water bodies pollutants in Indonesia, causing the spread of pathogens and bioaccumulation effects on the environment. The purpose of this study was to analyze the characteristics of household wastewater in Jakarta and Depok in terms of quantity and quality. The average wastewater quantity estimation results from laundry, bathroom, kitchen, and closet were 49 ± 18, 79.1 ± 5, 24.5 ± 12, and 29.9 ± 3 liters/person/day. The qualitative analysis results stated that blackwater tends to have higher concentration on conductivity 1606-2046 μs/cm, TDS 709-1007 mg/L, ammonia 78-167 mg/L, total nitrogen 511-836 mg/L, total phosphorus 16.6-21.3 mg/L, phosphate 33-46.8 mg/L, potassium 32.5-47.9 mg/L, and fecal coliform 430,000-1.600,000 MPN/100 mL compared to other sources. Meanwhile, laundry greywater tends to have higher concentration on COD 559-1991.6 mg/L, MBAS 0.3-0.31 mg/L, aluminum 1.65-5.09 mg/L, sodium 7.5-61.4 mg/L, and silica 17.7-23.2 mg/L compared to other sources. Statistical results show that some parameters have significant difference in average concentration between each source so that these parameters can be considered as source tracer. The high pollutant concentration and quantity leads to high estimation of pollutant load on the river, as water bodies receiver, in Jakarta and Depok, especially on organic and nutrient load.
Drainage System Evaluation as An Effort to Reduce Flood Inundation in Gedebage Area, Bandung - West Java
Authors: Sarminingsih A 
Published: November 2019

Abstract
Flooding in Gedebage area of Bandung is a recurring chronic problem. Various factors are alleged to be the cause of floods other than natural factors, such as several river courses across the region, and topography. The increase of runoff due to rainfall is not proportional to the drainage capacity. There are only two outlets which are Cinambo outlet and Cisalatri outlet. Various efforts have been made, such as dredging channels, rivers and elevating roads. However, those efforts have not solved the problem yet. Integrated efforts from upstream to downstream to address flooding in this region are needed. This study presents the results of an alternative evaluation of flood mitigation with several scenarios such as improving drainage channel capacity, channel addition, and combination of improving flow capacity and retention basins. The hydraulic analysis was performed using EPA-SWMM model. The analysis result shows almost some segments are overtopping. Increasing carrying capacity only reduces a few segments from overtopping. It needs a combination of increased channel capacity by widening and deepening, adding channels, creating a retention basin to overcome Gedebage flooding problems.

Published: November 2019

Abstract
Correlation between the size of copper nanoparticles and effects they produce on white mustard seedlings were studied in the paper. Copper nanopowders with average particle sizes of 45 and 200 nm with concentrations of 0.01–1000 wt ppm of seeds were used to treat white mustard seeds. Nonlinear dose effects were displayed by copper nanopowders obtained by chemical synthesis with the particle size of 35-60 nm. For 45 nm nanoparticles the highest biological activity with regard to germinating energy, 3-day stem and root weight was registered at 5.0 wt ppm concentration, while for root length and weight of the 7-day stems the 1.0 wt ppm concentration had the most pronounced effect. Copper submicron powder with average particle size of 200 nm displayed some effect only after 7th day of the experiment at high concentrations (from 100 to 1000 wt ppm) according to the measurements of length and weight of the seedlings. The obtained results can be used in the development of copper nanoparticles-based preparations for pre-sowing treatment of seeds.

Abstract
Foothill forest plantations of the Karachay-Cherkessia Republic are considered in this paper. The plantations are created by sowing and planting, strip or group tree espacement, both clear and mixed in composition. Thirteen permanent test plots with a total area of 4 hectares were laid. Six of them were laid in the Cherkessk-Elista-Volgograd State Forest Protection Zone (the Stalin’s Nature Transformation Plan of 1948). Complete enumeration of trees was carried out on each trial plot, defining their preservation, condition and quality. Models (from the trees of medium diameter and height) were selected. The graphs of growth progress in height and diameter were constructed. The calculation of barrel and stock volume was based on special tables. Environmental and economic assessment of the plantations (Kuban forestry, the Karachay-Cherkessia Republic) was carried out. The assessment was based on the methodology by V Tarankov. The calculation of carbon reserves was carried out by the calculation and measurement method using special tables. The current growth of plant phytomass was calculated through the intensity of carbon sequestration. Assessment of carbon dioxide absorption and oxygen evolution was carried out by the calculation method. The research is based on the method of comparison and analysis using variation statistics, which significantly improved the reliability of the data. For the first time, the experience of creating forest plantations in the foothills of the Karachay-Cherkessia Republic is summarized. The research makes a basis for planning and reconstruction of artificial stands in the foothills of the North Caucasus (eastern part).

Published: November 2019

Abstract
The paper discusses the topical issues of investment activities enhancement in the forest sector of the Russian economy by implementing the mechanism of priority investment projects in the field of forest exploitation – economic model of public-private partnership proposed by the forest owner (the State) for the private sector. The aim of the considered investment projects is the development of a timber-processing infrastructure, which is reliably provided with wood raw materials. It becomes possible to ensure certain preferences for businessmen that encourage them to invest money into the forest sector. Thus, the other objective is to develop recommendations for attracting investments into the forest sector of the Russian economy in the framework of priority investment projects. The paper analyzes a ten-year experience in the practice of applying priority investment projects in forest exploitation using an integrated approach to studying project management issues and method of comparison. The research identifies positive moments and a number of organizational and methodological shortcomings related to the development and implementation of investment projects in the forest sector of the Russian Federation. A number of areas contributing to the development of investment activities in forest exploitation is proposed.

Published: November 2019

Abstract
The study sites is located in an iron-mining district of European part of Russia, called The Kursk Magnetic Anomaly. Birch tree (Betula pendula Roth) plantation was created in 1972 in two different types of heap dumps (hydraulic-mine dumps and mining dumps). Afforested dumps are mainly consisted of cenomanian and aptian sands with the admixture of mesozoic carbonate rocks. In particular hydraulic-mine dumps are formed with sand material and mining dumps are formed with sandy-lime material. For improving poor properties of sand substrate before the planting birch trees on hydraulic-mine dumps were used the technique of soil transfer. The re-spreading fertile layer of soil varies from 30 to 80 cm. Substrate quality varied considerably. Long-term growth and survival of birch tree were analyzed and volume per ha were calculated in different slope parts. Study results show that double-layer substrate with fertile layer (30-40 cm) on the top would not appear to be the best way to rehabilitate mine ecosystems and it has significant disadvantages. At the age of 38 years, common birch is characterized by sufficiently high growth parameters, but low survival.

Published: November 2019

Abstract
Effective interaction of society, government and business in a market economy is one of the main factors affecting the sustainable development of all sectors of the economy, including the forest industry. The aim of this work is to develop a concept and tools for assessing the impact of management decisions of individual economic entities of the forest industry on the sustainable development of the region as a whole. All economic management decisions are essentially divided into three groups: operational and production decisions, decisions on wages and decisions on profit distribution. The authors propose a tool to assess the impact of management decisions of forest industry enterprises on the sustainable development of the region using an integral indicator calculated as a result of summation of indicators characterizing the impact of management decisions of enterprises operating in the municipalities of the region.

Authors: Koroleva T , Yakusheva T 
Published: November 2019

Abstract
The ways of innovations in the forestry sector and the main problems arising in this regard are discussed in the present paper. The following reasons restraining innovative activities in forestry may take place, among the others, were pointed out: 1) inadequacy of the legal framework, together with forms, content and procedure, for submitting reports on the implementation of delegated authorities; 2) insufficient interest of the federal and regional governments in the Russian Federation in the field of forestry relations regarding innovations; 3) imperfection of the algorithm for the integration of research and advanced development results into the forestry practice; and 4) weak intersectoral management on providing coordination over activities to find an integrated solution to the problem of increasing the economic efficiency of the forest industry. Furthermore, mechanisms ensuring the formation and implementation of innovation policy in forestry were considered. It was noted that there is an urgent need for developing ways to broadly implement research and development results in leased forest areas provided for all types of using, for instant, cultivation of planting material, hunting, recreational activities, etc. Possible directions in the implementation of these mechanisms were proposed taking into account the successful experience of the Federal Forestry Agency and its subordinate organizations.
