Force balance in thermal quantum many-body systems from Noether’s theorem
Authors: Hermann Sophie , Schmidt Matthias 
Published: November 2022

Abstract
We address the consequences of invariance properties of the free energy of spatially inhomogeneous quantum many-body systems. We consider a specific position-dependent transformation of the system that consists of a spatial deformation and a corresponding locally resolved change of momenta. This operator transformation is canonical and hence equivalent to a unitary transformation on the underlying Hilbert space of the system. As a consequence, the free energy is an invariant under the transformation. Noether’s theorem for invariant variations then allows to derive an exact sum rule, which we show to be the locally resolved equilibrium one-body force balance. For the special case of homogeneous shifting, the sum rule states that the average global external force vanishes in thermal equilibrium.

Abstract
The spread of coronavirus disease 2019 (COVID-19) results in an increasing incidence and mortality. The typical diagnosis technique for severe acute respiratory syndrome coronavirus 2 infection is reverse transcription polymerase chain reaction, which is relatively expensive, time-consuming, professional, and suffered from false-negative results. A reliable, non-invasive diagnosis method is in urgent need for the rapid screening of COVID-19 patients and controlling the epidemic. Here we constructed an intelligent system based on the volatile organic compound (VOC) biomarkers in human breath combined with machine learning models. The VOC profiles of 122 breath samples (65 of COVID-19 infections and 57 of controls) were identified with a portable gas chromatograph-mass spectrometer. Among them, eight VOCs exhibited significant differences (p < 0.001) between the COVID-19 and the control groups. The cross-validation algorithm optimized support vector machine (SVM) model was employed for the prediction of COVID-19 infection. The proposed SVM model performed a powerful capability in discriminating COVID-19 patients from healthy controls, with an accuracy of 97.3%, a sensitivity of 100%, a specificity of 94.1%, and a precision of 95.2%, and an F1 score of 97.6%. The SVM model was also compared with other common machine models, including artificial neural network, k-nearest neighbor, and logistic regression, and demonstrated obvious superiority in the prediction of COVID-19 infection. Furthermore, user-friendly software was developed based on the optimized SVM model. The developed intelligent platform based on breath analysis provides a new strategy for the point-of-care screening of COVID and shows great potential in clinical application.

This research concluded that rainfall affects the catches of fish larvae because it is directly related to the oceanographic condition of the bay waters.
The sensitivity of meteorological drought index towards El Nino-Southern Oscillation
Authors: Koem S , Lahay R J , Nasib S K 
Published: November 2022

Abstract
El Nino-Southern Oscillation (ENSO) contributes to the regional climates, such as precipitation and droughts. The objectives of the present work were to: (1) identify the severity index; (2) analyze the correlation of SPI and RDI, and; (3) identify the response of SPI and RDI towards ENSO. SPI and RDI were calculated for time scales (3, 6, and 12 months), and these represented the seasonal and annual drought. The identification of the responses of the drought severity index, based on ENSO, consisted of several thresholds, namely weak, moderate, and strong. The correlational value and RMSE only represented the performance of SPI and RDI on different time scales. The drought severity index would decline along with an increase in the time scales. The strong El Nino phase could be significant to the seasonal and annual drought. In other words, ENSO was impactful on the precipitation and dynamics of drought. Drought periods were due to the moderate and strong El Nino phase, while the weak phase led to a normal condition. For this reason, ENSO could be functioned as an indicator to predict drought.

Abstract
Sampang Regency is susceptible to flood which caused by river overflow due to rainfall peak period and rising seawater. Kamoning watershed is one of an area that got annual overflow flood. While the coastal area of Sampang Regency faces rising-seawater flood/high-tide flooding. This research aimed to map the flood susceptibility class in Sampang Regency using a morphological approach. Remote sensing and GIS analysis was used to classify the area into three flood susceptibility classes: high, moderate, and low. After that, the map is verified using hydrostratigraphy analysis using the geoelectric Schlumberger method. Based on the identification, 6 villages in 9 subdistricts located alongside the Kamoning River have a high flood susceptibility owing to river overflow. On the other hand, rising seawater is causing floods in Sreseh Sub-District, Jrengik Sub-District, Pangarengan Sub-District, Sampang Sub-District and Camplong Sub-District in the southern part of Sampang Regency, whereas Banyuates Sub-District, Ketapang Sub-District and Sokobanah Sub-District in the northern part. Consequently, those areas are also classified as high flood susceptibility areas. The hydrostratigraphy analysis showed that the surface of Sampang Regency is mainly composed of clay. With low permeability level (0.0002 m/day), water pools and surface runoff could easily be generated when rain falls.

Abstract
This research was conducted in the tsunami prone area of Parangtritis, Yogyakarta. The purpose of this study is to classify and analyse the distribution of anthropogenic landforms, as preliminary information to identify the potential exposure to tsunami. The method used in this research is descriptive-comparative, i.e. by comparing the variations of anthropogenic landforms typology within the present management zones (core, restricted, supporting zone). For each zone, the type of human intervention were identified with regard to the following classification: industrogenic, urbanogenic, traffic, agrogenic, water management, tourism, and sports. The anthropogenic landforms are then classified into excavation, planation, and accumulation types. The results of the study were presented in the form of tables and maps of anthropogenic landforms in each management zone. Assessment of the level of exposure to tsunami hazard is carried out qualitatively for each anthropogenic landform in the different management zones. This research revealed that type of intervention in each management zone are varied. The supporting zone and restricted zone have the most complex interventions, i.e. industrogenic, urbanogenic, traffic, water management, tourism, and sports. The excavation, planation, and accumulation forms are very diverse, depend on the people activities in each management zone. A particular human activity in the study area has a certain level of exposure to tsunami hazard. It is necessary to consider for reducing the specific risk to tsunami.

Published: November 2022

Abstract
Land valuation is one aspect of the cadastral system that is integrated with land use and land tenure. Land can be valued on the basis of the benefits that can be given. High and low land values are influenced by many factors, including economic, social, government, and physical factors. Based on factors that can determine the value of the land, it is known that the use of land (zoning) can also affect the formation of land values. The statistical analysis of a good land value model must take into account the effect of the location (X, Y) of the land parcels with the variable determining the land value comprehensively plus the city service center variable. The estimation model of land values resulting from the integration of linear regression and non-linear regression can be used as a reference to a single value for various purposes. The resulting land value estimation model is expected to reflect the true value.

Published: November 2022

Abstract
Galunggung is an active volcano with an altitude of 2168 meter above sea level. Galunggung Volcano has a diversity of vegetation and habitat for various fauna. Previous research explained that Galunggung Volcano has at least 43 species of typical plants, which are divided into categories of mature trees, poles, saplings, and seedlings / undergrowth. However, the spectral characteristics of these plant types are still unknown. On the other hand, remote sensing with infrared channels is the right technology to analyze the spectral characteristics of vegetation in Galunggung Volcano. Therefore, this study aims to analyze the specific characteristics of vegetation on Galunggung Volcano based on height zones. This research uses Landsat 8 imagery, Aster GDEM imagery, and Hyperion imagery. It is expected that the results of image processing can show how the altitude affects the different spectral characteristics and types of vegetation in the study area.

Authors: Septianingrum R S , Haryono E 
Published: November 2022

Abstract
Serpeng and Sumurup are allogeneic rivers in Wonosari’s basin, which derive water to Gunungsewu karst drainage system. The river flow characteristics of their allogeneic system are influenced by the watershed and weather conditions of the area. In addition, quantitative morphometry plays an important role in hydrological processes with remote sensing and geospatial techniques used to carry out a morphometric analysis. SRTM (DEM) was an efficient tool for extracting morphometric parameters. The watershed of the Sumurup river was much wider, and covers a total area of 42.80 km2, with a length of the main river being 21.44 km, while the Serpeng watershed covers an area of 10.58 km2 and length of the main river has 8.85 km. However, morphometry of the drainage density of both of them was classified on a medium category which indicates the basin is moderate permeability and has susceptible to flooding and erosion process. The highest order of Sumurup river has 4th level stream orders with has an elongated shape and Serpeng has 3rd level stream orders with an oval shape. Comparative analysis of watershed in the allogenic system could represent the geomorphological expression on the spatiotemporal variation of hydrology behavior of both rivers.

Abstract
The Monitoring of paddy fields conducts to guarantee national food data. One of the ways is to use the Sentinel-1A (Synthetic-Aperture Radar) system with a spatial resolution of 10 meters and able to penetrate the clouds. The purpose of this research is the identification of the spatial distribution of rice planting period and planting patterns within one year. The variable is a value of rice plating period based on backscattered value on Sentinel-1A imagery. The image analysis method used supervised maximum likelihood classification with training sample based on ground truth survey to generate rice planting period. The rice planting periods was land preparation, vegetative, reproductive, generative, and fallow phase. The results showed that the backscatter value in the land preparation phase was very low (-25.81 dB), then continued to increase upon entering the vegetative phase (-20.64 dB), which achieve maximum value on reproductive phase (-14.82 dB). At the time of paddy field entering the generative phase, the backscatter value would drop to averages -17.76 dB. The fallow phase is characterized by backscatter values that are ascending or not patterned due to the absence of roughness changes on the paddy field’s surface. The results of the study found there are three times of rice planting period in Pabuaran Subdistrict. Moreover, the research found there are six rice planting patterns, which are (1) paddy-paddy-paddy, (2) paddy-paddy-fallow, (3) paddy-fallow-paddy, (4) fallow-paddy-paddy, (5) paddy-fallow-fallow, and (6) fallow-paddy-fallow. This research concludes that spatial distribution dominated with rice planting patterns is paddy-fallow-paddy and distributed spread around Pabuaran Subdistrict.

Abstract
The local government of Jakarta has limited capacity to meet the needs for residential. Therefore, A private developer has the opportunity to help the local government respond by building a large-scale planned residential named Bintaro Jaya. It is developed in the South Jakarta Area and the South Tangerang Region. The development caused a gated community and led to physical and social segregation with the previous local community. This research is aimed to identify the spatial segregation in Bintaro Jaya. These hypotheses are analyzed by using a socio-spatial approach and descriptive analysis. The method is interpreted from Google Earth Imagery map Landsat 8 OLI/TIRS based on the masterplan of Bintaro Jaya to identify delineation settlement status and field observation as an image interpretation data validation. This paper describes the phenomenon of spatial segregation that potentially can be exclusive space. The form of segregation is identified by walls, roads, and economic centers. In which the economic center can be a transitional space that functions as a communal space between segregations.

Abstract
Environmental damage caused by industrial development is not only a result of industrial activities, but also a result of the demands of human life which require humans to adapt to the environment and all its changes through education and technology. In this case, a change in human behavior in managing natural resources is needed as a solution to these problems. Environmental damage in the PT. X Bojenegara - Banten, which is engaged in the oil and gas industry is still happening. Most of the causes of environmental damage in the region of PT. X such as air pollution, water, and soil as a result of the behavior of workers who don’t have an attitude of environmental awareness in the work. Several factors, namely environmental awareness and Industrial Hygiene program used to see the connection with the behavior of workers at PT. X. This research was conducted at PT. X Bojonegara, Banten in February 2015 to March 2015 by using a quantitative approach. Data were collected by using questionnaires, field observation and in-depth interviews. There are 79 respondents and 5 informants which were analyzed by univariate, bivariate and multivariate statistics. The result shown that there are any relationship between environmental awareness and Industrial Hygiene program with worker behavior (R = 0.292). The correlation value of 0.292 indicates that the relationship between environmental awareness and Industrial Hygiene program with worker behavior is moderate. The conclusion from these results shows that the higher the environmental awareness and the more understanding of the Industrial Hygiene program, the better the behavior of the workers.
