Abstract
Changes in environmental conditions due to climate change have the potential to change the pattern of disease spread and reduce the degree of human health. Health is a human right and a vital factor for human activity. Indirectly, health plays an important role in supporting economic activity and national development. This study aims to analyze the potential economic losses to the health sector due to climate change. The economic impact is calculated from losses through increasing the prevalence of climate sensitive diseases in the future, including dengue fever, malaria, diarrhea, and pneumonia. The distribution of diseases based on climatic factors is used to estimate the total prevalence. The number of disease prevalence was obtained by sensitivity analysis which was adjusted to the results of the RCP 4.5 CSIRO and MIROC models. The results showed that the impact of climate change on climate sensitive diseases has the potential to affect Indonesia’s Gross Domestic Product (GDP) by 0.1% or equivalent to Rp. 7.6 trillion. Climate change is projected to trigger disasters more frequently, thus increasing health losses by up to 1.8% of Indonesia’s national GDP. Strengthening climate change adaptation action in the health sector needs more attention to reduce these losses

AbstractEnvironmental issues are a shared responsibility, concern for ecosystem stability, and environmental productivity. For this reason, government policies also lead to education which must also build a caring character for the environment. In a non-formal way, the education applies environmental care by synergizing all character-building aspects that care for the environment. This study aims to analyze the A-G-I-L Scheme as an effective social system in building the character of caring for the environment through the Adiwiyata program. The method in this research is descriptive qualitative with data collection techniques of observation and documentation. The results show that obtained ecological intelligence through education. Therefore, in environmental awareness, competence is needed in environmental awareness as an indicator of the student’s awareness of a healthy environment. Students developed their sensitivity, awareness, understanding, critical thinking, solving environmental issues, and forming environmentally sound ethics. The Adiwiyata program can help students develop a single “core competence” to practice the principles of sustainable development in society as responsible citizenship. The Adiwiyata program only can achieve the goal if all school components from the school leader, teachers, staff, students, and the students’ parents support the program.

Published: January 2022

AbstractSugar imports are carried out every year in Indonesia to meet domestic needs. The average sugar imports from 2015 to 2019 reached 4.34 million tons. The Spatial Plan of Lamongan Regency 2011-2031 proclaims the development of sugarcane plantations, but the priority assessment of the development area which takes into account the balance of sugarcane availability in the future has not been scientifically studied. This study aimed to analyze the priority areas for sugarcane plantation development in Lamongan Regency. Analysis of development priorities was carried out using the AHP-GeoTOPSIS method and involving six experts. The criteria used include the number of agricultural households, suitability, and availability of land for sugarcane, population, and the balance of sugarcane availability in each sub-district. Land use datasets were used to calculate the suitability and availability of land and the balance of sugarcane availability in each sub-district. Based on the analysis, there were five priority areas for land development. There four subdistricts to be developed are as follows: Ngimbang, Solokuro, Mantup, and Kedungpring with weight values of 0.797, 0.776, 0.726, and 0.683, respectively. The study results can be used as input for the development of sugarcane plantations within the spatial plan of Lamongan Regency.

Abstract
Plastic pollution has become a problem in recent years. Various methods are used to reduce and prevent plastic pollution. Many methods have been used to estimate the abundance and transportation of plastics in waters, especially rivers. This paper presents the use of an Unmanned Aerial Vehicle (UAV) to observe plastic waste in river flow. Monitoring plastic debris was conducted at the downstream part of the Citarum river in the Muara Gembong sub-district, Bekasi Regency, West Java Province, on March 6, 8, and 10, 2021. The type of drone used was the DJI Phantom 3 Pro. Data analysis uses the CVAT program developed by Intel to label images. The results show differences between visual counting and UAV, visual counting has a higher value than UAV, but VC might suffer from an observer bias. The counting bias is dependent on the current and the ability of the eye. On the other hand, the results of aerial surveys during the calculation process can be reinterpreted manually or automatically and corrected again. Monitoring plastic debris using UAVs can be an alternative to observing the plastic transportation process in rivers, especially in areas that are difficult to access.
An Analysis of Spatio-Temporal Water Vapor Variation in the East Java using Ground Based GPS Receivers
Authors: Susilo  , Handoko E Y 
Published: January 2022

Abstract
Water vapor plays a critical role in the global/regional scale of weather and climate changes. Traditionally, the water vapor measurement uses radiosonde balloons which are very sparse in the distribution. The utilization of GPS as a new method for studying water vapor has been studied in several publications. This research analyzed the precipitable water vapor (PWV) based on ground-based GPS receivers in the East Java region. In the first part, the datasets are compared. The Zenith Total Delay (ZTD) from GPS processing will be compared with the Zenith Path Delay from the International GNSS Service (IGS) results. The comparison of ZTD and ZPD shows a good agreement. The comparison of GPS PWV and Radiosonde shows a good agreement. The spatio-temporal of GPS PWV is correlated with the Monsoon Asian-Australian cycles that affect weather and climate in Indonesia. The result indicates that GPS data provide valuable information in meteorology and climatology.

Abstract
Demand for land use can cause an undesirable impact. Bali Island has been exploited as the midpoint of tourism activities and altering land use over the last two decades. Badung regency is the hinterland area of Denpasar City, the capital city of Bali Province. Land conversion in Badung was caused by the construction infrastructures related to tourism development. Conversion occurred from agricultural lands to built-up lands. This research analyzed remote sensing data, taking the advantage of abundant, serial data acquisition. This study used Landsat 7 ETM and Sentinel 2 satellite images obtained from 2010 to 2020. Land cover types were identified by visual interpretation and LULC changes were analyzed by overlaying land use maps. Identified land-use types included eight categories, i.e. paddy fields, forests, mangroves, built-up areas, mixed gardens/plantations, upland fields, shrubs, and water bodies. Land use has changed significantly in the past 10 years especially in built-up areas, upland fields, and paddy fields. The trend showed that built-up areas persistently increased from 2010 to 2020. Paddy fields, shrubs, mixed gardens/plantations, and mangroves fluctuated in terms of the acreage; rose from 2010 to 2015, but were reduced in the rest of the period. Water bodies did not change throughout.
Utilization of Indonesia’s regional ionosphere model to improve the accuracy of GPS measurements to support disaster mitigation studies
Authors: Safi’i A N , Susilo  , Ramdani D , Muslim B 
Published: January 2022

Abstract
Ionospheric can cause severe degradation of GPS (Global Positioning System) functionality and decrease coordinate accuracy. Increasing the precision of GPS station coordinates will improve accuracy in many applications. Many applications can use GPS for deformation studies, such as geodynamic studies, active fault studies, volcanic deformation monitoring, land subsidence studies, and hazard mitigation studies. We can use global ionospheric correction to produce better coordinates by utilizing post-processing GPS data. With the increasing number of GPS stations in Indonesia, it is possible to develop regional ionosphere models. This study computes regional ionospheric models from real-time streaming GPS data and uses them in GPS processing. Regional ionospheric models can increase the accuracy of GPS station coordinates by 5% -10% compared to global ionosphere models (igsg and codg).

Published: January 2022

Abstract
Spatial Planning (RTRW) is a policy direction and strategy for using regional space used as a reference by the Governments. Inconsistencies often occur between current land use (LU) and spatial planning. The research focus is a similar land use in villages/kelurahan on the border of the two regions. Similar land use is essential to compare inconsistencies in two adjacent districts/cities (e.g., inconsistency occurs in paddy fields in district A, not in district B). The research objectives are 1). Identify LU and its changes in the border area of Bogor Regency and City in 2010-2020, and 2). Analyze similar land use (2020) and alignment with RTRW. The analysis used is the logical matrix tabulation, geographic information system (GIS), and scalogram. The study locations identified 62 villages on the border of Bogor Regency and City. In the border area of Bogor Regency and City, the dominant land use is settlements, and between 2010 to 2020, there is an increase in the area of settlements by 2.196 hectares. This shows that regional development has expanded to the periphery. Furthermore, the alignment of land use with spatial patterns on similar lands in border areas can see the tendency of regional spatial planning policies, whether exploitation or conservation.

Abstract
The Subwatershed of Musi Hulu plays an important role in Bengkulu Province and the South Sumatra region. In 2006, the establishment of the Musi Hydropower Plant increases the functional load of the area hence, there is a need for sustainable land resources management. Therefore, this study aims to identify the key factors that affect sustainable land resources management in the Musi Hydropower Plant catchment area in Bengkulu Province. This research was conducted in the Musi Hydropower Plant catchment area in Rejang Lebong and Kepahiang Regency, Bengkulu Province, Indonesia. The method used was an Interpretive Structural Modelling (ISM) with four criteria, namely objectives, programs, barriers, and stakeholders of land resources management. The results showed that limited budget and weakness of coordination among stakeholders are the main barriers to sustainable land resources management in the catchment area. Meanwhile, non-governmental organization plays significant roles in supporting land resources management. Therefore, with the limited budget of land resources management, it is recommended to improve the coordination among stakeholders to maintain sustainability in the Musi Hydropower Plant catchment area in Bengkulu Province.

Abstract
The article presents the calculation of the stress-strain state of an earthen dam on a loess base on a computer. The calculation of the joint operation of the dam with the foundation was carried out using finite difference methods using shifted approximating grids (displacements and velocities are determined at the nodes of one mesh; deformations and stresses at the nodes on the other). The use of the developed algorithm, on the one hand, and the improvement of the mathematical model of the soil, based on experimental studies of samples for expansion, on the other hand, make it possible to assess the formation of trenches by calculation methods. The obtained calculation results are compared with the data of experimental model studies of the stress-strain state of an earthen dam with a subsidence base on a centrifuge. The correctness of the previously stated position was confirmed that for calculations of crack formation, the values of the limiting extensibility of the soil should be taken. It is necessary to determine these values by simulating the complex stress state of soil samples in laboratories. The areas of the dam have been identified as potentially the most in terms of cracking (a ridge zone with low compressive loads, close to uniaxial expansion in terms of operating conditions, and near-edge buried in places of a sharp break in the slope of the banks with significant stresses and destruction of soil material in a complex stress state by tension with sliding).

Abstract
The hydropower and water management complexes include pressure systems with pumping stations that supply the required amounts of water to specified heights. Modern pressure systems are complex and varied. The control elements of these systems, primarily pumping stations, are continually becoming more complex and improved. In this regard, the costs for the construction and operation of pressure systems with pumping stations can be very high, therefore, the issue of choosing the best option when designing these systems becomes especially important. In this case, it is necessary to take into account transient processes, that is, transitions in operational conditions from one stationary mode to another. A significant change in these parameters leads to a violation of the normal operation of pressure systems, premature failure of their individual elements, and sometimes to accidents. Despite the accumulated experience in the construction and operation of pressure water supply systems, there are still no sufficiently general methods for calculating transient processes that ensure an increase in the reliability of structures. The paper presents the mathematical modeling of the calculation of transient processes in pressure water supply systems, the main directions for their further improvement are given.

Published: January 2022

Abstract
Grape regenerant plants obtained from apical meristems were assessed for the presence of the viruses using PCR and enzyme-linked immunosorbent assay (ELISA). The vast majority of the samples studied for the presence of the most common viruses (Grapevine Leafroll-Associated Virus – 1 (GLRaV-1); Grapevine yellow mosaic virus; Grapevine vein banding; virus; Grapevine Leafroll Virus; Grapevine stemm pitting) by ELISA showed negative results. Testing of regenerant plants of the Augustine variety clones showed that only one plant out of 80 plants showed a positive reaction to the presence of this virus. Analysis of 80 plants of the Moldova variety clones revealed a positive reaction to the yellow mosaic virus (Grapevine yellow mosaic virus) in 1 plant as well as in the original donor plant (Moldova variety). The rest of the regenerated plants (79 pcs.) were absolutely healthy. PCR analysis showed that the spectrum of fragments of the original genotypes of Moldova varieties (lanes 1–4) and Augustin (lanes 5–8) contained DNA fragments of 450 bps, corresponding to Candidatus Phytoplasma vitis Flavescence doree. In Bart variety (lanes 9–11), no pathogen was detected. Analysis of the spectrum of fragments of grape regenerant plants obtained from apical meristems (lanes 1–4) and Augustine (lanes 5–8) showed the absence of the pathogen Candidatus Phytoplasma vitis Flavescence doree.

Authors: Chekusov M S , Kem A A , Schmidt A N , Keruchenko L S 
Published: January 2022

AbstractFour wheels are installed on the frame in the front part, the rear part of the frame is supported by two rows of rollers to ensure stable operation of the Stepnyak-7.4 cultivator in depth and maintain the required ridgeness of the soil field. The speed of movement of the unit, the depth and the running uniformity of working tools, and the traction resistance of the machine depend on the ridgeness and microrelief of the field. A priori ranking of factors of the cultivator’s operation revealed that the most significant factors in studying the ridgeness of the cultivated soil are the speed of movement of the unit Va, the diameter of the rolling basket drum Drb and the setting angle of the scraper γ. The variation levels of natural factors are established and values of coded values of factors are calculated. An orthogonal central composite design was used to design the experiments. Based on the results of experimental data processing, a mathematical model of field ridgeness variation after processing depending on the varied factors is obtained, and rational ranges of operational parameters are determined. The studies revealed that the minimum ridgeness of the field soil is achieved with a rolling basket diameter of 0.40-0.45 m and an inclination angle of the scraper bend of 75-80 degrees with a unit speed ranging from 2.8 to 3.2 m/s.

Published: January 2022

AbstractThe paper experimentally assesses the characteristics of grape raw materials (vines, leaves) in terms of quantitative and qualitative composition of polyphenols - the main functional biologically active ingredients of grape processing products. For obtaining alcoholic extracts, vines and leaves of grape were pre-dispersed and extracted using the ethanol. The extraction was carried out at room temperature for several months until an equilibrium concentration of polyphenols was obtained. The extracts were separated by leaking off on a sieve. The qualitative and quantitative composition of polyphenols in alcohol extracts was determined by the HPLC method. The analysis of the obtained data shows that a broad array of polyphenols appropriate for grape pomace, seeds and stalks (flavones, flavan-3-ols, hydroxy-cinnamic, oxybenzoic acids, stilbenes, oligomeric and polymeric procyanidins) is present in vine and leaves.
