Published: November 2021

AbstractThe crust, when viewed over a long period, moves towards one another. Crusts might experience sudden slip on a fault plane and caused fractures or cracks. There are three different types of faults, normal, reverse, and strike-slip faults. Induced stress due to sudden rupture on fault planes capable of creating stress and need to be measured quantitatively to comprehend the earthquake process. To understand the stress that occurs in strike-slip faults in the earth’s crust, the previous researchers study the use of elastic materials as the material of the earth’s crust, so that the earth crust’s deformation is elastic. However, elastic material has linear stress and strain relationship that results in reversible deformations or returns to their original shape. This material is not suitable for modeling the earth’s crust’s long-term deformation, where the deformation of the earth’s crust can be permanent, so a model is needed to solve this problem. In this study, we will compare the stress in the strike-slip fault in the upper crust with elastic materials, while the lower crust and upper mantle have viscoelastic materials compared to purely elastic materials through numerical simulations. This comparison is made to see the comparison between the two approaches with the earth’s layers’ actual state. The two models is chosen to represent the different failure processes of the earth crust, i.e. the elastic deformation part describes the response to stress in a short period, and the viscous deformation can explain the response over a more extended period. The study of both materials above is based on plate tectonic theory, in which the lithosphere plates will relatively move to each other because the layer material underneath is solid but can flow like a liquid for a long period.

Abstract
Hypocenter relocation is one of the keys to success in the analysis of seismicity induction in underground mines. Overburden thickness, topography, geological complexity, and mining activities can result in newly induced seismicity that can endanger the safety of underground mine workers. The relatively narrow underground mine area requires the most accurate hypocenter location information possible. The double-difference algorithm approach is one of the keys to overcoming this problem. The double-difference method is a relative location method that tries to minimize the residuals between the observed and calculated travel time differences for pairs of microseismic events at each station, by adjusting the differences between all pairs of events at each station repeatedly. In this study, we utilized microseismic measurement data in the deepest underground mine in Indonesia. A total of 1783 seismic events were successfully relocated. The relocation results show the rock mass stress which is illustrated by the distribution of events around the cave, especially the abutment area and underground mining tunnels.

Published: November 2021

AbstractPresent day Molucca or Maluku sea plate in the eastern of Indonesia possesses a complex tectonic setting. This complex tectonic setting has been formed due to the collision of an actively moving Eurasian plate and Philippine sea plate toward the Maluku sea plate. At the west, Maluku sea plate is subducting beneath Sangihe arc, which began in the early Miocene. While at the east, Maluku sea plate is subducting under Halmahera arc, since in the middle Miocene. These subduction processes take place up to the present. Therefore, it has formed Maluku sea plate into an inverted U-shape slab under a thickening accretionary complex. Seismicity distribution has clearly shown the U-shape slab. Earthquake events take place on the subducting slab, and interestingly on the above accretionary complex as well. Maluku sea plate might pose hazards to surrounding islands: northern Sulawesi, Halmahera island, Sangihe island and Talaud island. The possible hazard, for instance, a thrusting earthquake which may generate tsunami to the nearby islands. Hence, understanding its tectonic and seismicity signature, especially at the shallow part, are indeed important in the Maluku sea region. Faulting regime could be analyzed using focal mechanism ternary diagram analysis, by categorizing the focal mechanisms’ strike, dip and rake values. Thus, in this study we aim to analyze faulting regime and hazard potential in the complex. Maluku setting using ternary diagram analysis.

AbstractShear-wave splitting (SWS), or the propagation of two independent shear waves, can be used as an indicator of seismic anisotropy. In this study, we utilize this concept using aftershock data of the 2018 Lombok earthquake which had been acquired in period of August 4 – September 9, 2018. The goal of this research is to better understand the crack distribution related to the rupture zone of the 2018 Lombok earthquake. After applying instrument correction to the data, the waveform data were then windowed in each P and S arrival time. To determine the SWS parameters, we performed rotation in each horizontal seismogram components. The horizontal components were rotated from azimuth 0° to 180° with an increment of 1°. Cross-correlation coefficient (CCC) was determined for each rotation angle. The polarization direction and the SWS delay time were chosen from the parameters shown in the highest value of CCC.

Abstract
On 31st March 2020, Indonesia pulls out a large scale social restriction (LSSR) policy to depress the spread of Covid19. The regulation leads to the lay-off of schools, workplaces, worship places, and public facilities, including public parks. Despite the time, it is only a matter of time until the new normal and reopening of all public facilities. For that, public parks as public facilities should be prepared in a way before it is reopened so as not to worsen the situation or even create a new pandemic wave. It is an excellent opportunity to build better by applying health protocol for a healthier future, and transforming the future sustainable landscape. This research is studying two public parks in Bogor City, a satellite city of the megapolitan Jakarta area, which affected the most by Covid19, i.e.,, Sempur Park and Kencana Park. This research aims to explore users’ perceptions and preferences of using public parks to plan health protocol for public parks in the new normal era. Data collected through an online questionnaire survey. As much as 192 responses are analyzed. Data and instruments are valid and reliable, with an overall Cronbach alpha value of 0.896. Results showed that the perception of park use pre-LSSR and post-LSSR was significantly different. The trend of park use was similar but at different levels. This indicates that the motivation and willingness to visit and use public parks is decreasing, therefore applying health protocol is a necessity in the future. This study also found that existing parks perceived to be quite appropriate in accordance with health protocols and need to be moderately modified. Another finding was that the considered most required health protocols application were procurement of handwashing facility, park benches placed at least 1 meter apart, and solitary park bench. It is elicited that despite the type of park, the visitors’ preference was the same.
The political economy of soil erosion in Cirasea sub basin, upstream Citarum basin
Authors: Nurysyifa F , Kaswanto  , Kartodihardjo H 
Published: November 2021

Abstract
The current problems of the Upstream Citarum basin, particularly in the Cirasea Sub-Basin, are near related to economic factors and the low political position of the community. One of the reasons is the biophysical aspect, which influenced the erfpacht rights for Dutch and British plantation companies in the Agrarische Wet policy at the end of the 17th century. When Indonesia became independent, the Government had worked on environmental rehabilitation as well as dealing with land conflicts, but rehabilitation activities often failed to meet the primary needs of the community. Therefore, rehabilitation efforts in various programs often fail. The objective of this this study is to figure out the preferences of interests and motives from the government and other access authorities which ultimately affect the lives of other communities through the formulation of an environmental rehabilitation program. The approach is Bernstein Political Economy Analysis. The results show that political economy is be able to reveals the problem of erosion, which is always imposed on groups with a low political position compared to other groups who are more vital in reaching access. Even though the community has limitations in implementing environmentally-friendly agricultural practices. Moreover, the political economy can reveal the government’s interests behind the land rehabilitation program which often sided with big investors and even tended to repeat the pattern of conflicts in the colonial era. Therefore, erosion can be an important element in describing the conditions of poverty that occur in rural areas.

AbstractDue to the acceleration of urbanization, many green spaces are facing the fate of abandonment, especially the urban and suburban green space. In Japan, these suburban green spaces can also be used as a Satoyama. Satoyama is a multi-purpose ecosystem, including some secondary forests, farmlands, lakes, marshes, and so on. They are affected by human beings and benefited each other. It is proof of harmonious coexistence that human beings have been groping for in nature since ancient times. This study collected the records of the Satoyama activity group in Matsudo City, Chiba Prefecture, Japan from 2008 to 2019, and used KHCoder3 to mine the characters. The purpose of this study was to identify that it is found that people use suburban green space in variety nowadays through the activities of volunteers in Satoyama. From the records, the green space has a series of changing stages after becoming Satoyama, in which 2008-2011 is the first stage, and 2016-2019 is the other stage, but 2012, 2014, and 2015 were grouped separately. In addition to the daily maintenance of the forest, there were also some special words that can be seen that people attach great importance to the publicity of Satoyama as a place for Children’s environmental education. For the future, Satoyama activities can afford good references to urban green space multi-function, maintain ecological balance, and keeping sustainable development.

Published: November 2021

Abstract
Jakarta is a city that has a reasonably dense population and continues to grow every year. The rapid increase in the number of residents has caused a lack of harmony between the need of land for housing and existing land availability. This condition has led to a change in the function of riverbank in the area of settlements which happened in Pejaten Timur, South Jakarta. The existing settlements area on the riverbank caused environmental problems such as river width change and pollution. These conditions caused this area is often flooded every rainy season. Therefore, this research was conducted to design the Ciliwung Riverbank and restoring the function of its riverbank which was supposed to be a green open space. Green open space is designed in the form of an urban community park that can be used as a water catchment area, improving the ecological function of the riverbanks, and as a place to relax for the citizens around the site. The design of the park is carried out by the design process method, these design process included preparation, inventory, analysis, synthesis, and site design. In the analysis section, the writer determines the potential and site constraints, and then some appropriate site development plans can be produced. The applied concept is called “Eco-relaxing riverside park”, which is an urban park on the riverbank that is environmentally friendly and has the primary function of a place to relax for visitors. The result of the urban community park design is expected to increase the aesthetic and functional value of the Ciliwung Riverbank in Pejaten Timur, South Jakarta. The final result of this research is the site plan, overall perspective, spot perspective, visible section images, detailed drawings, and explanations of the images.
Continuity of heritage urban landscape: the case of Jeron Beteng Yogyakarta
Authors: Rahmi D H 
Published: November 2021

Abstract
The urban landscape, which is in a dynamic environment, continues to change, meaning it has transformed the relationship between humans and the environment. Many changes have occurred since the early formation of the city until now. Nevertheless, many heritage urban landscape that has been formed hundreds of years ago are continuing to date with their various elements remain the same. Jeron Beteng is a part of the Yogyakarta Sultanate Palace, which has existed since the early construction of the palace. This traditional area was once a residential area for the abdi dalem (people who served the Sultan and Palace) and the sultanate princes or brothers of the Sultan. Along with the developments of Yogyakarta, Jeron Beteng has developed into a dense urban settlement. Various changes have occurred, both the function of the area, architecture building, and land use. As a heritage area, it is interesting to know whether Jeron Beteng can adapt to the changes and continue as the cultural identity of the Yogyakarta Palace. This paper is based on research that intends to identify the urban landscape characters of Jeron Beteng and examine the continuity of its physical landscape characters as the cultural identity of the Yogyakarta Palace. A qualitative method is used with two approaches: interpretation of the history of Jeron Beteng and qualitative approach based on the contemporary empirical phenomenon. This research found that Jeron Beteng today is the culmination of hundreds of years of physical and social management. It is not just a collection of heritage buildings, events, and precincts, but the whole landscapes, that have unique characters. The character of Jeron Beteng is mostly formed by its physical elements that have heritage values, mainly the Palace, Alun-alun, and the beteng wall. Changes in the spatial and physical environment have happened, however, the essence or core of the physical landscape character of Jeron Beteng is continuing and contributes to the cultural identity of the Yogyakarta Palace and the city.

Published: November 2021

AbstractThe development of high way that crosses wildlife habitat will inevitably cause wildlife casualties. The purpose of this study was to identify wildlife road mortality in Rawa Aopa Watumohai National Park, Southeast Sulawesi (mostly consisted of savanna). Road kill data was collected by driving along the 22.4 km highway in February and March 2020 (n=28). Traffic volumes were recorded by taking traffic samples in 5 different times of the day, an hour duration each (totaling 70 h). There were 37 species being killed (totaling 529 individuals, of which 49.3% happened along km 0-10), consisted of 19 bird species, 3 small mammal species, 10 reptile species, and 5 amphibian species. Based on taxa, the highest number of road mortality was amphibians (dominated byIngerophrynus biporcatus), followed by birds (mostlyLonchura malacca), mammals (dominated byRattus argentiventer), and reptiles (dominated byVaranus salvator). Among mammals, no big mammal (booted macaqueMacaca ochreata, wild boarSus scrofa) was killed. Landscape transformation clearly has impacted wildlife in the study area. To reduce the occurrence of road kills, it is recommended to create corridors for wildlife crossings, limiting vehicle speed in the hot spots locations, create speed bumps, as well as adding more signage and road signs along the highway.

Abstract
This article examines the features of the formation of the population of the city of Ulan-Ude - the capital of the Republic of Buryatia (Russia). It shows how socio-economic and administrative changes have affected the total population, the share of the city in the overall population structure, as well as how the territorial structure has been transformed over the past 60 years. In the post-Soviet period, urbanisation has affected not only the capital city itself, but also suburban areas, while small towns and urban-type settlements have largely lost their prospects for territorial and demographic development. Unlike other regional centres of the Far Eastern Federal District, Ulan-Ude is experiencing population growth due to both migration and natural increase. The study is based on the analysis of official data from the All-USSR and All-Russian population censuses and the results of annual statistical reports by Rosstat and Buryatstat.
Comparative analysis of renewable energy development in the Republic of Buryatia (Russia) and Mongolia
Authors: Badmaev A G 
Published: November 2021

Abstract
The constantly growing demand for electricity and relatively small energy capacities are forcing the Republic of Buryatia (to a greater extent) and Mongolia, which are limited in some types of economic activity, to look for new sources of energy. One of these restrictions is the ban on the construction of hydroelectric power plants on rivers of the Lake Baikal basin. Therefore, Buryatia and Mongolia have taken the path of building environmentally friendly power plants and have succeeded in many ways. Despite the high costs of setting up clean power plants, infrastructure investments in alternative energy are long-term and expected to be profitable. Investors (including foreign ones) placing their money in a seemingly low-profit project, having long-term expectations. Competent investors do not run after “quick money”, realising that the return period of the constructed power plants will be long, as at the moment of development they have a relatively low efficiency. Despite the criticism of some researchers [1], they invest in green energy, modern infrastructure and a future without emissions (CO2, NO2, SO2 and other gases) from burning coal, fuel oil and firewood. Other experts see in the development of alternative energy a great potential [2-5], refuting arguments of critics about high cost of electricity [6].
