Published: November 2021

Gedebage district is presently experiencing rapid and mass infrastructure development and becoming one of the developed districts in Bandung, Indonesia. A football stadium, several luxury housing, the grand mosque of West Java province, and a business center have been built in this district. However, it is well known that the Gedebage district has turned into one of the Bandung districts that suffers from land subsidence phenomena. Since 2000, the Gedebage district has suffered land subsidence at an average rate of 10 cm per year and becoming one of the fastest sinking districts in Bandung. This fast land subsidence phenomenon is suspected of affecting the infrastructure in this district. Therefore, this work aims to capture the current subsidence rate in the Gedebage district using the geodetic approach of the combination of the Global Navigation Satellite System (GNSS) with Interferometric Synthetic Aperture Radar (InSAR) and investigate the impact of land subsidence on infrastructures in Gedebage district. We use GNSS campaign datasets from the years 2016 and 2019. Each GNSS campaign was performed at least 10-12 hours of observations. We also utilize a similar period of 2016 to 2019 for the InSAR datasets. Utilizing both GNSS and InSAR datasets, we can capture the subsidence with the rate reaching 4 -15 cm per year between 2016 and 2019, and it occurs uniformly in this district. The impact of land subsidence occurred in almost all urban areas in the Gedebage district. These impacts include cracks in buildings, bridges and roads, and also tilted buildings.

To use the Global Navigation Satellite System (GNSS) correctly, the height information should be transformed into orthometric height by subtracting geoid undulation from it. This orthometric height is commonly used for practical purposes. In 2015 geoid of Jakarta has been produced, and it has an accuracy of 0.076 m. In the year 2019, airborne gravimetry has been done for the entire Java Island. The area of DKI Province cannot be measured because there is inhibition from Airnav. For this reason, terrestrial gravimetric measurements are carried out in this region by adding points outside the previously measured area. To compute the geoid in the Jakarta region is needed the Global Geopotential Model (GGM). In this paper, the GMM used is gif48. The “remove and restore” method will be used in calculating the geoid in this Jakarta region. Besides that in this geoid calculation also uses Stokes kernel and FFT to speed up the calculation. The verification of the resulting geoid is carried with 11 points in DKI Jakarta Province. This verification produces a standard deviation of 0.116 m and a root mean square of 0.411 m.

The receiver function method is a method to image the earth subsurface by utilizing Ps conversion waves that are formed due to the velocity boundary. In general, the receiver function method estimates depth of structures such as the mantle-crust boundary by deconvoluting the vertical component from the horizontal component. Typical receiver function data processing is done in the frequency domain where the deconvolution process can be seen as a division between two components. In this study, we tried to reprocess the data using a deconvolution technique in time domain, popularly known as iterative time-domain deconvolution. The principle of iterative time domain deconvolution consists of iterative cross-correlation between the horizontal and vertical component. We use data from the DOMERAPI seismic station network located in the vicinity of Mt Merapi and Mt Merbabu. Mt Merapi is one of the most active volcanoes in the world with frequent eruptions and located at the ring of fire chain volcano in Indonesia. Note that the previous receiver function study in this region showed complex signals at some stations that may be related to sediment at shallow sediment and possible layers of low velocity zone that interfering main signal for a crust-mantle boundary. Our current results show iterative time domain RFs have clearer and smoother signal than the frequency domain that help interpreting the waveform signals. We estimate a range of crust thickness between 26-31 km near Mt Merapi. However, we noticed that iterative time domain calculation requires longer computation time and input signal.

Published: November 2021

The 2020 Sumbawa earthquake of moderate magnitude (M 5.3) produced very significant aftershocks. Based on the computation of Utsu’s method, those aftershocks would be ended after the 20th day. Those earthquakes along 20 days were relocated using double-difference method. The relocation results show the southwest-northeast orientation and getting deeper into the northwest direction. Those two directions show the strike and the dip from the fault plane of the earthquake which was consistent with the focal mechanism released by the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG). Those results showed the majority of earthquakes occurred at a depth of shallower than 20 km. Those earthquake depths were fit with the previous study showing the crustal thickness beneath Sumbawa Island that was about 28 km. We also found that those earthquakes occurred at splay faults propagating to decollement structure. This study is beneficial for earthquake disaster mitigation especially in updating active faults on Sumbawa Island.

The area of Sulawesi, especially along the Palu Koro Fault, is an area that is largely influenced by the confluence and movement of plates as well as regional fault activity pathways with high levels of seismicity. Determining the location of the hypocenter accurately through relocation is required in identifying the detailed tectonic structures in the area. Relocation of the hypocenter using the Modified Joint Hypocenter Determination (MJHD) method using the IASP91 velocity model in the period August to October 2018 with the arrival time data from BMKG catalog. The results of hypocenter relocation using the MJHD method show that from 132 earthquake distribution points to 63 earthquake hypocenter points after the relocation. The change in the location of the hypocenter was much denser along the Palu Koro Fault route than before the relocation as evidenced by the mean value of rms (root mean square) before relocation was 1.31 and after relocation it became smaller (0.61). Changes in parameter values after relocation using the MJHD method caused the distribution of the earthquake hypocenter to be tighter towards the Palu Koro fault than before the relocation, where the distribution had a random and scattered pattern.

Published: November 2021

Ironsand deposits might contain Fe as well as other valuable elements and minerals that could be used in a variety of applications. Often, high Fe content deposits are preferable for exploration. An earlier study shows that the highest Fe content is found in the very fine sand (VFS) size. In this study, seven VFS samples from Anoi Itam were subjected to magnetic measurements as well as X-Ray florescence (XRF), X-Ray diffraction (XRD), and correlation analyses to investigate further characteristics and how magnetic susceptibility correlates with the elemental composition of ironsand. Magnetic susceptibility varies from 2207.77 × 10-8 m3 kg-1 to 4476.68 × 10-8 m3 kg-1. The main elements contained in the sample are Fe, Ti, Si, and Al. Meanwhile, other elements have small concentrations (<2%). Based on XRD analyses, magnetite and ilmenite are the main minerals with varying concentrations in each sample. The correlation analysis shows that magnetic susceptibility has a weak correlation with Fe probably because Fe forms minerals with very different magnetism, namely magnetite and ilmenite.

Published: November 2021

On May 27, 2006, 05:54 am local time, a moderate crustal earthquake of magnitude Mw 6,3 struck the Yogyakarta province, especially in the Bantul regency in the south part of the province. The earthquake damaged or destroyed more than 400,000 houses and buildings and caused more than 5,700 people killed. Several earthquake stations recorded the ground vibration caused by the mainshock very well, except at the stations closest to the earthquake source, namely YOGI in Gamping, West of Yogyakarta, which experienced saturation due to significant vibration. Therefore, information about the maximum ground acceleration near the source is yet not known. We model the ground vibrations near the earthquake source using a stochastic Green’s Function approach to obtain information about the ground motions’ maximum amplitude. The earthquake source parameters we referred to is the moment tensor solution from the Harvard Moment Tensor. The calculations show that the amplitude is consistent with observations recorded at the BJI Banjarnegara (0.04g) and YOGI Yogyakarta (0.3g).

Published: November 2021

The existence of seismic wave velocity difference in the Earth crust and mantle creates the possibility to use earthquake data for estimating the crustal thickness utilizing the Ps conversion phase in the boundary. The radial component signal was deconvolved from the vertical component in the frequency domain to estimate receiver function for Indonesia region. We implemented the water level deconvolution techniques with a Gaussian filter of 2.5 Hz to eliminate the high frequency noise in the receiver function. The H-k stacking technique was performed to all receiver functions from each event to predict the crustal thickness and the Vp/Vs ratio below the stations. We analyzed ten azimuthally distributed teleseismic earthquakes recorded by 108 stations of BMKG. The result shows that the crustal thickness in Indonesia varies from 20 to 39.9 km. The western part of Sumatera, northern part of Sulawesi Island, and North Maluku region show generally thinner crust with value about 20 to 25 km. The North Sumatera, Central Java, and East Java show a considerably thicker crust of up to 36 km. Furthermore, our result also reveals a difference of crustal thickness about 5 km with the previous studies.

The existence of anisotropy phenomena in the subsurface will affect the image quality of seismic data. Hence a prior knowledge of the type of anisotropy is quite essential, especially when dealing with deep water targets. The preliminary result of the anisotropy of the well-based modelling in deep water exploration and development is discussed in this study. Anisotropy types are modelled for Vertical Transverse Isotropy (VTI) and Horizontal Transverse Isotropy (HTI) based on Thomsen Parameters of ε and γ. The parameters are obtained from DSI Logging paired with reference δ value for modelling. Three initial conditions are then analysed. The first assumption is isotropic, in which the P-Wave Velocity, S-Wave Velocity, and Density Log modelled at their in-situ condition. The second and third assumptions are anisotropy models that are VTI and HTI. In terms of HTI, the result shows that the model of CDP Gather in the offset domain has a weak distortion in Amplitude Variation with Azimuth (AVAz). However, another finding shows a relatively strong hockey effect in far offset, which indicates that the target level is a VTI dominated type. It is supported by the geomechanical analysis result in which vertical stress acts as the maximum principal axis while horizontal stress is close to isotropic one. To sum up, this prior anisotropy knowledge obtained based on this study could guide the efficiency guidance in exploring the deep water environment.

According to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), an average of 20 typhoons a year visits the Philippines; and one of the significant repercussions of typhoons is flooding. Due to worsening and intensifying typhoons, the flooding problem is also getting worse, and two of the main reasons for this are land subsidence and sea-level rise. Marilao, Bulacan, is one of the Philippines’ municipalities experiencing worsening flood levels. This study tackles an environmental approach to making the municipality adaptive and resilient to flooding by finding the most appropriate use of the land areas of Marilao – to benefit both the environment and its users. The study identified and analyzed the causes of flooding, using relevant maps such as hazard maps, existing land-use plans, and projected land-use plans to draft an effective plan for the municipality. After which, generating projections of the land conditions in the next century was done; to ensure that the proposed plans will accommodate future scenarios within the landscape. These data, along with four possible scenarios on the problems of the site, were analyzed. With this, the study took upon one of the approaches that led to the 2060 Environmental Protection Plan, which primarily focuses on addressing landscape requirements.

Published: November 2021

Urban development has many negative impacts in the form of an increase in the concentration of CO2 in the air. One of them is due to the increase in the volume of vehicles. CO2 causes an increase in global temperature (global warming) through the greenhouse effect. Yogyakarta International Airport has a green open space planted with trees to support the existence of the airport itself. Trees have contributed to efforts to reduce CO2 in the air through CO2 absorption. Control of the amount of CO2 emissions in the air is done by adding carbon stocks on land so that the CO2 concentration does not continue to increase, therefore this research is necessary. The purpose of this study is to analyze the ability of trees to absorb pollutants and store carbon and estimate the value of environmental services that will be contributed by the tree green system at Yogyakarta International Airport based on existing planting plans. The research method used is modeling using CITYGreen 5.2 software to determine the value of tree services in the ability to absorb air pollution, carbon storage capacity, and cost savings that can be done by tree canopies. The method used in this study consisted of preparation, data inventory, and data analysis. The results of this study show that the value of environmental services provided by 125,72 acres of tree canopy cover in absorbing air pollution in the airport area is $ 9.045,54 / year or equivalent to Rp 133.356.587,10 per year, the total concentration of pollutants that can be absorbed is 3.813,30 lbs/year or equivalent to 1.729,68 kg/year, and the capacity of carbon storage is 1.326,46 tons with a sequestration rate of around 29,9 tons/year.

The Government of Bantaeng Regency, South Sulawesi Province is one of the first districts established policies to support community-based forest management and to adopt the Ministry of Forestry (Kemenhut) policy on Community Forests (CF – Hutan Kemasyarakatan HKM) and Village Forests (VF – Hutan Desa HD. There is one VF located in Pattaneteang, which has characteristics and great resource potential. In the VF management process, several problems arise in conflicts between villages over boundaries that increase with reducing the landscape as a resource. The utilization of a geographic information system (GIS) in landscape management is expected to provide complete information for managing the form of VF areas integrated with each other. This study aims to produce a precise map of the VF area based on the image map of the drone results. The latest methods are used to produce accurate delineation of the region through drone participatory mapping (DPM) technology involving several related parties. DPM is a group-based research method that gives participants the freedom to make discussions on topics with minimal intervention from researchers. Simply put, it is an activity in which villagers choose to location referencing and other features related to the topic given on the map. The participatory monitoring method was carried out through a Focus Group Discussion (FGD). The results showed that Pattaneteang Village which, has an area previously about 1303.81 ha after the village was carried out, participatory mapping reducing became 1107.79 ha, then participatory mapping was carried out based on the result of the drone, Pattanetang area was obtained to be 1109.92. While the extensive VF based on Decree of the Minister of Forestry No.55 / Menhut-II / 2010 dated January 21, 2010, Pattaneteang VF forest area was 339 ha after drone based-participatory mapping (DPM) to 429,71 ha related to three types of forest, namely Core Forests, Utilization Forests, and Dispute Forests are covering 48.15 ha, 198.12 ha. and 181.43 ha, respectively. The results of this study can be used as a reference in planning sustainable village forest management areas.
Fore Karst: A Biotope-focused planning approach for the ecological management of Susong Dalaga, Quirino
Authors: Lavilla D , Navarra N , Palarca N
Published: November 2021

Conventional planning approaches that prioritize built-up areas and rapid urbanization for economic growth and social security, instead of the environment and the ecological services they provide have consistently been problematic in maintaining sustainability. Because of this, there is a growing need to shift from the conventional to a greener approach. The research argues that an ecological management approach is a viable choice of approach in protecting the ecological integrity of the landscape, especially in biotopes where ecological services are sought-after, such as the karst system Susong Dalaga found in Cabarroguis, Quirino Province. This approach is done by identifying the different biotopes to find the existing relations, services, and underlying issues of the place. In assessing the items mentioned earlier, the research finds that the natural systems are slowly dwindling due to the expansion of agriculture and built-up areas. Each biotope is then assigned with an appropriate approach, and with the consultation of the stakeholders, policies are then strategized for specific functions. It is hoped that the study would help push the application and integration of ecological management approach, and green approaches and principles in general, to future urban planning projects in the Philippines.

Authors: Murad A R P , Syartinilia
Published: November 2021

Javan Hawk-Eagle (JHE, Nisaetus bartelsi) is an endemic species in Java Island and an important biological indicator of ecosystem health. The government has issued regulations to protect this species and increase the population by 10% from 2015 until 2019. East Java has the largest JHE potential habitat in Java Island based on a previous study using satellite images of 2002. Therefore, the current habitat distribution of JHE’s is essential for getting knowledge about patch dynamics in JHE’s habitat. This study’s objective was to analyze patch dynamics of JHE’s habitat from 2002 until 2015 and validate habitat distribution. Previously predicted probability map (2002) of JHE’s were updated using Landsat 8 satellite images of 2015 and was validated through ground-truth checked. Results showed that the distribution of JHE’s habitat after validation is 28 patches, which is covered 4766.26 km2. The dynamics that occur in the JHE’s patch are patch lost(1 patch), patch area decreased (5 patches), patch area increased (13 patches), new patch (4 patches), and merged patch. After validation, there are six newly identified patches, and one patch area increased. The total area increased by 2156.14 km2 or 82.61% of the total area occupied by JHE’s in 2002. About 39.89% of total habitat patches were located inside the protected area. This study recommends continuing monitoring activities on habitat patches, including potential habitat patches in lowland areas, and proposing conservation activities based on habitat patch dynamics that occurred from 2002 to 2015.

Authors: Zabortseva T I
Published: November 2021

The Laboratory of Economic and Social Geography of the V B Sochava Institute of Geography SB RAS (Irkutsk, Russia) has been carrying out socio-economic research in the indicated field over the past decade. We consider the Siberian macroregion traditionally within the space of Western and Eastern Siberia with the inclusion of the Republic of Sakha (Yakutia). The research results reflect, firstly, the growth path of Siberia in the new millennium, taking into account the multidirectional external and internal factors. Secondly, our findings include the identified spatial patterns of the main socio-geographical structures (specialization of existing industries, infrastructure, market and non-market services and the population) as the basis of regional policy with the aim of sustainable development, ensuring the modern level of quality of life of Siberians. We studied the key Baikal region in more detail.
Social marginalization in regions of Siberia and Far East of Russia: Factors, Features, Trends
Authors: Babkin R A
Published: November 2021

The social marginalization is one of the most acute problems of modern Russia as it results in its development slowdown and a loss in its social and human capital. The marginalization is particularly wide-spread in the regions of the Asian part of the country. The marginalization is characterized by a complex of problems including the social diseases, the spread of crimes in various forms, the economic and social benefits deprivation, etc. Due to the impoverishment of the human capital, the progress is slow in the Siberian and Far Eastern regions, and this threatens the sustainable economic development here. In this paper, the authors propose a system of indicators and a methodology enabling a comprehensive assessment of the social marginalization. An attempt is made in the paper to link some statistical indicators of the social deprivation with the most striking characteristics of the marginalization in the society. Also, in the paper, the heterogeneity and the regional specificity of this phenomenon are shown. The main factors of geographic, economic, cultural and institutional origin making their impact on the level of marginalization have also been identified.

Authors: Bardakhanova T B , Munkueva V D
Published: November 2021

The object of the research is the Russian border areas of North Asia, which include Tyumen Oblast, Omsk Oblast, Altai Krai, Tyva Republic, The Republic of Buryatia, Zabaikalsky Krai and Amurskaya Oblast. This research aims to conduct a comparative analysis of agricultural development in these territories over a long period from the early 1970s to the present. The authors have analysed the dynamics of the gross regional product of the considered regions and its structure, the share of agriculture in GRP of the regions, the volume of agricultural production (in US dollars), cultivated areas and a number of indicators of agricultural development efficiency. Conclusions are made about the low role of the considered regions in the formation of the RF GDP, as well as about the insignificant share of agricultural products in GRP of the regions and the decreased efficiency of agricultural land use in comparison with the average indicators for the Russian Federation.

Published: November 2021

In this paper we revealed the problems of development of border rural areas, causing their low economic and social attractiveness. We determined that the development of border rural areas involves the formation of mechanisms for the growth of economic and social activity. The methodological basis of the study is the concept of development of border rural settlements as the most important parts of the economic space. This development is based on the integrated use of economic, social and environmental resources while launching innovative and diversification projects as part of the regional development strategy. We showed the need to form a network of growth centres throughout the region, just as competing for economic, social and environmental resources, so complementing each other in terms of integrated use of resources. The global mission of border rural areas in the innovation economy as well as possible incentives to increase the socio-economic attractiveness of rural areas have been identified. The need for state support for cross-border rural areas was economically justified by identifying opportunity costs. A policy of “smart” protectionism and its effectiveness for the development of border rural areas was described. We proposed a model and main mechanisms for the development of economic, social and environmental activity in the border rural areas. We also revealed the specifics of development of border rural areas of the Republic of Buryatia where world heritage sites are located.

The uneven development of countries and regions is one of the major topics of geography. Since its subject, as defined by N N Baransky, is the difference from place to place. Considering economic activity, socio-economic processes and indicators in the territorial aspect, we are confronted with the inequality of their distribution across the territory. This problem is particularly relevant, because the objective reality, due to the diversity and uniqueness of local conditions, as well as historical, economic, political reasons. Currently, there are various approaches to measuring socio-economic asymmetry. The “centre-periphery” model is remarkably resilient and flexible, and is able to maintain its properties under different socio-economic conditions. Based on statistical analysis (1995-2018), GRP per capita by regions of Russia was examined, as well as correlation coefficients.

Authors: Zhamyanova Y B , Darbalaeva D A
Published: November 2021

In modern conditions, human capital is of great importance in the production of the value of goods and services. At present, the social and living conditions of people in rural areas lag far behind urban ones. Russia has identified a socially oriented model of society development among the development priorities for the coming years, which involves the support of social spheres of the economy that determine the conditions for human capital development. The article discusses the main conditions for the formation of human capital in rural areas of North Asia, which covers the territories of the least populated federal districts – Siberian, Ural and Far Eastern. The selected entities are different in terms of economic development and infrastructural potential. The article highlights the main factors in the formation of human capital and the conditions for its development in this region. The importance of the role of the state in ensuring the availability and improving the quality of social services, reducing the differences between rural and urban living conditions is shown.
Interregional cooperation in the Russian Federation in the post-COVID reality: challenges and prospects
Authors: Violin S I
Published: November 2021

The COVID-19 pandemic has seriously distorted the public administration systems around the world. In certain countries, like the Russian Federation, the pandemic has triggered different responses by authorities on a regional level. This article argues that the lack of the interregional coordination has exacerbated the negative effects of the pandemic both on the economic development and the well-being of citizens. The goal of this research is to search for ways to improve interregional cooperation in crises of interregional scale and importance. The main hypothesis is that the lack of interregional coordination leads to ineffective crisis management and unnecessarily prolongs the recovery process. Retrospective, statistical and comparative analysis have been used to test this hypothesis. On the example of Russia, the system of crisis management coordination on the interregional level is introduced and explained. The results of this research can be used for public policy in Russia and other federal states as well as to study coordination mechanisms on a supranational level.
Poverty and inequality in the light of modern approaches to overcoming Russian poverty
Authors: Belousova S V
Published: November 2021

The subject of the article is the phenomenon of poverty in light of the problems of excessive economic inequality, which is the main source of formation of Russian poverty, and indicative of institutional analysis which involves a critical revision of social-economic policy of the state instead of the official way of dealing with this problem without considering the reasons of its formation (targeting of poverty). The aim of the work is to update the cause-and-effect factors of poverty formation in Russia, the main of which is a critically high level of inequality with an assessment of the role, nature and causes of its causes. The hypothesis of the study is the thesis that the fight against poverty is ineffective based only on increasing the number and level of social payments and social programs, without taking into account the causes of poverty, thus not affecting any socio-economic processes for its formation. Meanwhile, both the indicative and institutional approach to the analysis of the main causes of poverty shows the dominant role of excessive inequality in the formation of the problem of Russian poverty. In turn, inequality is caused by the inefficiency of the state’s distributive and redistributive policies, caused by the lack of scientific conditionality and systematic political decisions.
