Published: February 2022

Abstract
As one of the most active volcanoes in Indonesia, Merapi Volcano has potential risk towards the inhabitants living nearby. After the 2010 paroxysmal eruption, Sister Village program was established in Magelang Regency as an alternative strategy to a better disaster management by evacuating people living in the highest volcanic disaster-prone area (affected villages) to safer zones (buffer villages). By taking location in Tamanagung Village, Muntilan Sub-district, Magelang Regency as buffer village, this research tries to understand how the Sister Village program is implemented in this area, specifically to understand community and infrastructure preparedness. The study used both quantitative and qualitative data taken directly in the field by using questionnaires towards 40 respondents, checklists, and interview with keypersons. Community preparedness were analyzed using four parameters: knowledge, policy and guideline, emergency response plan and resource mobilization. The results showed that among four parameters, only knowledge parameter showing a good preparedness, while the four others still need to be improved. The use of information technology by the public, such as Whatsapp application, is widely growing. In terms of infrastructure preparedness in the buffer village, some enhancements in terms of capacity, infrastructure safety, health aspects, and comfort are still necessary.

Published: February 2022

Abstract
Biomass production supports humans need for food so needs to be supported by optimal soil conditions. The study related to the potential for soil degradation in land characteristics is the first step for sustainable agricultural control. Potential soil degradation is compiled from the number of scores for each land map unit (soil type, slope, rainfall, land use) using technical guidelines for the preparation of soil degradation, and the Pearson correlation test to examine the causal relationship of soil degradation from each land characteristic. The results show that the land with the highest potential is with moderate level potential of 4,671.83 hectares (46.44% area) and the other part of 3,953.13 hectares (39.30% area) has low potential level. The main factors for potential soil degradation are the slopes, rainfall, and land use. The steeper the slopes and the high rainfall carried out on intensive agricultural land, the greater the degradation to the soil. Suggested land management strategies include soil conservation with minimal tillage, mulch application, terrace construction, and planting parallel to the soil contour. In addition, erosion research needs to be carried out to determine in detail the magnitude of the erosion prediction in this area.

Abstract
Rahakolowu Watershed is an important and strategic issue area for the South Buton Regency. The characteristic of this region is in the form of hills and having wavy until the very steep slope which is very potential of having high run-off. The purpose of this study was: 1) to determine the potential for surface run-off that occurs in the Rahakolowu Watershed; 2) to map the potential for flash floods that occur in the Rahakolowu Watershed. The approach used in this study was a modified HRU (Hydrological Response Unit) with a run-off occurrence land unit as its unit analysis. Based on the result, the highest run-off water discharge produced in each sub-basin was an average of more than 0.50 m3/sec, both on forest, moor, residentials, mix garden and shrubs. The high slope and the area of each land unit in a flow occurrence is the factor causing the high run-off in the Rahakolowu Watershed. Flash floods occur along the main river channel and become inundation floods when they reach downstream. The accumulation of run-off in the southern sub-basin has more potential as a flood contributor in the Rahakolowu Watershed.

Abstract
The eruption of Mount Kelud in February 2014 released eruptive material that caused lava flooding from the sub-watershed. Lava floods cause land-use changes, land damage, and infrastructure damage. Ngantang Sub-district Malang Regency is the area most severely affected by the eruption of Mount Kelud. This paper aims as a preventive effort to reduce disaster risk through spatial evaluation of vulnerability due to lahar sediments and directives for infrastructure and settlement planning in volcanic areas. Using scoring and map overlay techniques for vulnerability analysis and planning directions. The findings highlight that villages along the river have a higher level of vulnerability and disaster risk and are not recommended to build and use land within a 100 meters radius of the river wall for various community activities. Another finding is the lack of strong indicators of disaster risk reduction capacity in Ngantang Sub-district. This phenomenon proves that there are still many challenges to realizing disaster risk reduction as mandated in Law No. 24 of 2007 and Regulation of the Head of BNPB No. 2 of 2012.

Abstract
Urbanization has changed landscape patterns and ecological functions, resulting in a decline in service ecosystem services and environmental problems, especially in areas experiencing rapid Urbanization. The increase in population will affect the development process and affect land needed to support daily activities, and affect the temperature that triggers the Urban Heat Island phenomenon. A better understanding of the relationship between Urbanization and ecosystem services is critical to future regional sustainability and relevant policy development. This study aims to assess the relationship between Urbanization and ecosystem services in the urban area of Solo Raya, consisting of 7 districts/cities, namely Surakarta, Boyolali, Sukoharjo, Wonogiri, Sragen, and Klaten. The research method used is spatial quantitative descriptive analysis to analyze the impact of Urbanization on ecosystem services in 2020 in an isolated Solo Raya urban area. Ecosystem services are calculated from food production and Urbanization rate measured from four aspects: population, population growth, population density, and land expansion. The results show that areas with a high urbanization rate are automatically viewed in terms of Ecosystem Services. The region will be in deficit or not a self-sufficiency area. In other words, it shows that there is a relationship between the level of urbanization and ecosystem services.

Abstract
Clean Ecosystem service measurement model for urban population clean water monitoring Clean water as one of the ecosystem services and also a protected natural asset provides important information about the availability of natural resources for humans in response to the impacts of climate change and overall ecosystem health. The emergence of the COVID-19 pandemic which was exacerbated by the emergence of low-pressure areas for piped clean water services (PAM water) increasingly shows that if humans destroy biodiversity, it will have implications for other life support systems including clean water. This study identifies aspects of quantity, continuity, and quality (called 3K) of clean water from the piping system in the eastern part of DKI Jakarta, especially in areas with low pressure water supply. Through the Research and Development method, the aim of the study is to build a new model for measuring ecosystem services in monitoring clean water for residents in urban areas. Until the end of the first semester of 2020, the results of the study showed that it was true that there were areas with low pressure, but statistically it was not proven to significantly affect the emergence of complaints in terms of quantity, continuity, and quality of water supply to the population, so more in-depth parameters are needed. regarding the parameters of small water complaints (quantity), dead water (continuity), and piped clean water quality.

Published: February 2022

Abstract
The article discusses modern views on the problem of pipeline waxing when transporting highly paraffinic oil from the Kyrtaelskoye field in the Komi Republic via the Kyrtael - Chikshino oil pipeline and possible ways to improve the rheological properties of the pumped oil. The paper presents the results of measuring the rheological characteristics of samples from one batch of oil as it flows through the pipeline, as well as the results of modeling the operation of the pipeline in the NIPAL 3.0 program for various pumping options. It has been established that, taking into account the complex rheological properties of oil pumped through the interfield oil pipeline PPSN “Kyrtael” - PSP “Chikshino”, the operation of the oil pipeline is possible at pumping volumes of at least 2300 tons / day due to an increase in the critical operating pressure in the oil pipeline. At the moment, a Flexoil depressant is injected into the oil stream to improve the rheological parameters. In connection with a gradual decrease in the volume of oil pumping, the speed of oil movement decreases and the temperature of the pumped oil decreases below the pour point. Even with the use of a pour point depressant, the pipeline will not be able to operate at the beginning of 2024 (according to the existing operation scheme). The analysis of the problem of pumping oil through an interfield oil pipeline performed in this work shows the need to achieve optimal parameters for pumping oil during the operation of the pipeline under consideration in order to ensure the safety of oil transportation from the Kyrtaelskoye field and further pumping into the system of Transneft-Sever JSC into the Usa-Ukhta main oil pipeline. The paper considers standard methods of oil heating with the help of line heaters, as well as the method of oil heating on the linear part of the interfield oil pipeline using induction flow heaters, which were first proposed when pumping oil through the oil pipeline PPSN “Kyrtael” - PPSP “Chikshino”.

Published: February 2022

Abstract
The possibilities of using blockchain in the electric power sector are analyzed based on a study of key blockchain projects and startups initiated by the world’s leading electric power companies, defining the type of blockchain platform, as well as the goals and contribution of each project to improving energy efficiency. The key types of blockchain projects in the electric power industry have been identified. The authors came to the conclusion that in the Russian Federation, despite the large number of startups, including pilot blockchain projects, the demand for such developments is constrained by the insufficient development of the regulatory framework in the field of electricity and tariff regulation. Studying foreign experience of legislative regulation and practical application of blockchain in the electric power industry will make a significant breakthrough in achieving the goals set by the concept of “Digital Transformation 2030”

Abstract
This article discusses the solution to the problem of active proppant removal from a hydraulic fracture into the wellbore. To reduce the amount of proppant removed not only at the stages of well development, but also during its operation, it is proposed to compact the proppant pack in the created hydraulic fracture with elastic hydraulic waves, which can be generated using a hydraulic spool vibrator. Well treatment according to the technology described in the article makes it possible to attract additional formation fluid to the working agent during hydraulic vibration treatment in field conditions. The use of this technology when testing an exploration well in an oil field has shown high efficiency in terms of increasing its oil production rate.
