Authors: De Oliveira E Silva Francisca , Soares Julio Cesar Mendes , Valdez Aniele , da Silva Ferreira Marcos Vinícios , da Silva Cecim Marcelo
Published: September 2021

:

Essential oils are complex mixtures of volatile compounds, primarily composed of terpenes and abundant aromatic plants. For example, Cymbopogon citratus (lemongrass) is an aromatic plant that produces a monoterpene-rich essential oil, and studies show that this essential oil has excellent antioxidant activity. Erythrocytes incubated under high sugar levels are constantly exposed to reactive oxygen species, which results in the oxidation of their membranes.

Objective:

The aim of this article is to investigate the antioxidant activity of lemongrass essential oil and its protective effect on erythrocytes exposed to high levels of glucose.

Materials and Methods:

The essential oil was obtained by steam dragging distillation; blood cell suspensions were incubated with glucose 5, 20, 50, and 100 mmol/L. The amount of TBARS produced was measured at 532 nm. In addition, the percentage of antioxidant activity was assessed by DPPH free radical assay.

Results:

Lemongrass essential oil showed an increase in the antioxidant activity up to 240 mg/ml, while ascorbic acid used as positive control showed a dose-dependent increase in antioxidant activity starting at 1 mmol/L up to 18 mmol/L. However, such a lemongrass dose prevented peroxidation in erythrocytes incubated under a high glucose media, whereas ascorbic acid showed a protective effect only at a concentration of 1 mmol/L.

Conclusion:

Lemongrass essential oil has high antioxidant activity compared to standard antioxidant as ascorbic acid, and also acts as a protective agent against erythrocyte lipoperoxidation due to hyperglycemia in vitro.

Authors: Wu Tingting , Hu Yanxin , Liu Xianqing , Wang Changhong , Zeng Zijin , She Zengwei
Published: September 2021

Background:

The employment of Phase Change Materials (PCMs) provides a potential selection for heat dissipation and energy storage. The main reason that hinders the wide application is the low thermal conductivity of PCMs. Combining the proper metal fin and copper foam, the fin/composite phase change material (Fin-CPCM) structure with good performance could be obtained. However, the flow resistance of liquid paraffin among the porous structure has seldom been reported, which will significantly affect the thermal performance inside the metal foam. Furthermore, the presence of porous metal foam is primarily helpful for enhancing the heat transfer process from the bottom heat source. The heat transfer rate is slow due to the one-dimensional heat transfer from the bottom. It should be beneficial for improving the heat transfer performance by adding external fins. Therefore, in the present study, a modified structure by combining the metal fin and copper foam is proposed to further accelerate the melting process and improve the temperature uniformity of the composite.

Objective:

The purpose of this study is to research the differences in the heat transfer performance among pure paraffin, Composite Phase Change Materials (CPCM) and fin/Composite Phase Change Material (Fin-CPCM) under different heating conditions, and the flow resistance of melting paraffin in copper foam.

Methods:

To experimentally research the differences in the heat transfer performance among pure paraffin, CPCM and Fin-CPCM under different heating conditions, a visual experimental platform was set up, and the flow resistance of melting paraffin in copper foam was also analyzed. In order to probe into the limits of the heat transfer capability of composite phase change materials, the temperature distribution of PCMs under constant heat fluxes and constant temperature conditions was studied. In addition, the evolution of the temperature distributions was visualized by using the infrared thermal imager at specific points during the melting process.

Results:

The experimental results showed that the maximum temperature of Fin-CPCM decreased by 21°C under the heat flux of 1500W/m2 compared with pure paraffin. At constant temperature heating conditions, the melting time of Fin-CPCM at a temperature of 75°C is about 2600s, which is 65% less than that of pure paraffin. Due to the presence of the external fins, which brings the advantage of improving the heat transfer rate, the experimental result exhibited the most uniform temperature distribution.

Conclusion:

The addition of copper foam can accelerate the melting process. The addition of external fins brings the advantage of improving the heat transfer rate, and can make the temperature distribution more uniform.

From Biological and Non-Biological Surfaces
Authors: Shukla Sandeep Kumar , Sharma Ajay Kumar , Kalonia Aman , Shaw Priyanka
Published: September 2021

:

Covid 19 is a pandemic disease spread almost in the whole world. To date, no medical
advancement to curb the virus. Coronavirus is an enveloped virus transmitted from the biological
and non-biological surface by direct or indirect contact. Limited literature revealed that the enveloped
virus can be killed by disinfectants. There are many biocidal agents used for decontamination
of the virus, yet they have many issues like toxicity, killing time, activation requirement, etc.
Some are specific to the inanimate surface but not used by a human being. This current situation
showed an urgent need for a biocidal agent which can act on biological as well as non-biological
surfaces without any potential toxicity. Moreover, it should be easy to handle, inexpensive, and
safe for the environment. Hypochlorous acid is a weak acid that acts as a powerful disinfectant and
shows biocidal efficacy against a wide range of microorganisms. Hypochlorous acid is simple to
use, inexpensive, eco-friendly, non-toxic, and stable. The properties of HOCl can be regulated at
the site of preparation and therefore, its compliance is high. Hypochlorous acid seems to be a
promising agent in disinfection and sterilization in healthcare facilities. Due to its diverse biocidal
actions, it may be used as a potent disinfectant against novel coronavirus.
Scandi-Noir in Portuguese: in pursuit of textual transits
Authors: Valente Anabela Quaresma
Published: September 2021

Following the global success of Stieg Larsson’s Millennium Trilogy(2005), Scandinavian crime fiction has attracted considerable attention from researchers in literary studies and other domains. However, a gap still remains with regard to the translations of this sub-genre in Portugal and Brazil. To address this gap, this article attempts to demonstrate how crime fiction produced in Sweden, Denmark and Norway has been disseminated in Portugal and Brazil by means of a bibliographic survey that traces the various transit routes that exist between these (semi-) peripheral languages. The results indicate that indirect translation continues to play an important role in this process, contrary to some predictions.
The first translation of Freud in Portugal
Authors: Hörster Maria António Hörster , Plag Cornelia
Published: September 2021

: The first translation of Freud published in Portugal appears to have been a version of the 1905 text Drei Abhandlungen zur Sexualtheorie, which came out in November 1932 named Sexualidade.Published by the Ática Pressin a collection entitled Scientia Vitæ, the translator's name –Osório de Oliveira –was,surprisingly,displayed in a prominent position on the title page. A comparison between this translation, Freud's original and a French version by Blanche Reverchon, that had come out shortly before, shows that it was a case of indirect translation, which reproduced many of the characteristics of the intermediary version. Forexample, while Freud's original enables the reader to follow the thought processes behind his hypotheses and scientific conclusions, both of the translated texts are much less tentative. This paper explores the circumstances surrounding the production of this Portuguese translation at that moment, the translational options made, and the effect of both on the text's reception. Particular attention is given to the domain of lexis –creation of neologisms, terminological consistency and coherence –and modalization, and whether the terminological options caught on and were reproduced in subsequent translations and commentaries.

To evaluate the effect of calcium salts of long-chain fatty acids (CaLCFA) and protein supplementation on body weight (BW), average daily gain (ADG), pregnancy rate (PR), and blood chemistry, 57 Brahman heifers with 309.1 ± 3.04 kg BW and 1,010 ± 8.51 days of age, were divided into three BW uniform groups and assigned for 102 days to three treatments under a completely randomized design: 1) grazing forage only (F); 2) F+CaLCFA, and 3) F+CaLCFA+protein-energy mix (CaLCFA+CP) with 453 protein g/kg, containing mainly (g/kg) CaLCFA (200), hydrolyzed feather meal (300), and cornmeal (375). About 0.2 and 1 kg/animal/d of CaLCFA and CaLCFA+CP were offered, respectively, with an average intake of 200 and 192 g/animal/d for the same order of supplements. The breeding period (BP) lasted for 45 days and started 57 days after beginning the supplementation period. Body weight showed a treatment × time interaction (p < 0.01), being different at the end of the BP (348; 338 and 331 kg, respectively for CaLCFA, CaLCFA+CP, and F). Average daily gain (g/d) was higher (p < 0.01) for CaLCFA (358) than for CaLCFA+CP (281), and lower for F (206). Overall, PR was higher (p < 0.05) for CaLCFA+CP (68.4 %) and lower for F (36.8 %). Cholesterol (mg/dL) was higher (p < 0.05) for CaLCFA+CP (139) and lower for F (117). Calcium salts of long-chain fatty acids and CaLCFA+CP supplementation improved BW and ADG of Brahman heifers at first mating, while PR and cholesterol increased only with CaLCFA+CP supplementation.

Authors: Liu Yi-Shiuan , Yang Chih-Yu , Chiu Ping-Fang , Lin Hui-Chu , Lo Chung-Chuan , Lai Alan Szu-Han , Chang Chia-Chu , Lee Oscar Kuang-Sheng
Published: September 2021

BACKGROUND

Hemodialysis (HD) therapy is an indispensable tool used in critical care management. Patients undergoing HD are at risk for intradialytic adverse events, ranging from muscle cramps to cardiac arrest. So far, there is no effective HD device–integrated algorithm to assist medical staff in response to these adverse events a step earlier during HD.

OBJECTIVE

We aimed to develop machine learning algorithms to predict intradialytic adverse events in an unbiased manner.

METHODS

Three-month dialysis and physiological time-series data were collected from all patients who underwent maintenance HD therapy at a tertiary care referral center. Dialysis data were collected automatically by HD devices, and physiological data were recorded by medical staff. Intradialytic adverse events were documented by medical staff according to patient complaints. Features extracted from the time series data sets by linear and differential analyses were used for machine learning to predict adverse events during HD.

RESULTS

Time series dialysis data were collected during the 4-hour HD session in 108 patients who underwent maintenance HD therapy. There were a total of 4221 HD sessions, 406 of which involved at least one intradialytic adverse event. Models were built by classification algorithms and evaluated by four-fold cross-validation. The developed algorithm predicted overall intradialytic adverse events, with an area under the curve (AUC) of 0.83, sensitivity of 0.53, and specificity of 0.96. The algorithm also predicted muscle cramps, with an AUC of 0.85, and blood pressure elevation, with an AUC of 0.93. In addition, the model built based on ultrafiltration-unrelated features predicted all types of adverse events, with an AUC of 0.81, indicating that ultrafiltration-unrelated factors also contribute to the onset of adverse events.

CONCLUSIONS

Our results demonstrated that algorithms combining linear and differential analyses with two-class classification machine learning can predict intradialytic adverse events in quasi-real time with high AUCs. Such a methodology implemented with local cloud computation and real-time optimization by personalized HD data could warn clinicians to take timely actions in advance.
(Mis)Information on Digital Platforms: Quantitative and Qualitative Analysis of Content From Twitter and Sina Weibo in the COVID-19 Pandemic (Preprint)
Authors: Kreps Sarah , George Julie , Watson Noah , Cai Gloria , Ding Keyi
Published: September 2021

BACKGROUND

Misinformation about COVID-19 on social media has presented challenges to public health authorities during the pandemic. This paper leverages qualitative and quantitative content analysis on cross-platform, cross-national discourse and misinformation in the context of COVID-19. Specifically, we investigated COVID-19-related content on Twitter and Sina Weibo—the largest microblogging sites in the United States and China, respectively.

OBJECTIVE

Using data from 2 prominent microblogging platform, Twitter, based in the United States, and Sina Weibo, based in China, we compared the content and relative prevalence of misinformation to better understand public discourse of public health issues across social media and cultural contexts.

METHODS

A total of 3,579,575 posts were scraped from both Sina Weibo and Twitter, focusing on content from January 30, 2020, within 24 hours of when WHO declared COVID-19 a “public health emergency of international concern,” and a week later, on February 6, 2020. We examined how the use and engagement measured by keyword frequencies and hashtags differ across the 2 platforms. A 1% random sample of tweets that contained both the English keywords “coronavirus” and “covid-19” and the equivalent Chinese characters was extracted and analyzed based on changes in the frequencies of keywords and hashtags and the Viterbi algorithm. We manually coded a random selection of 5%-7% of the content to identify misinformation on each platform and compared posts using the WHO fact-check page to adjudicate accuracy of content.

RESULTS

Both platforms posted about the outbreak and transmission, but posts on Sina Weibo were less likely to reference topics such as WHO, Hong Kong, and death and more likely to cite themes of resisting, fighting, and cheering against coronavirus. Misinformation constituted 1.1% of Twitter content and 0.3% of Sina Weibo content—almost 4 times as much on Twitter compared to Sina Weibo.

CONCLUSIONS

Quantitative and qualitative analysis of content on both platforms points to lower degrees of misinformation, more content designed to bolster morale, and less reference to topics such as WHO, death, and Hong Kong on Sina Weibo than on Twitter.

The Willingness to Pay for Telemedicine Among Patients With Chronic Diseases: Systematic Review (Preprint)
Authors: Chua Valerie , Koh Jin Hean , Koh Choon Huat Gerald , Tyagi Shilpa
Published: September 2021

BACKGROUND

Telemedicine is increasingly being leveraged, as the need for remote access to health care has been driven by the rising chronic disease incidence and the COVID-19 pandemic. It is also important to understand patients’ willingness to pay (WTP) for telemedicine and the factors contributing toward it, as this knowledge may inform health policy planning processes, such as resource allocation or the development of a pricing strategy for telemedicine services. Currently, most of the published literature is focused on cost-effectiveness analysis findings, which guide health care financing from the health system’s perspective. However, there is limited exploration of the WTP from a patient’s perspective, despite it being pertinent to the sustainability of telemedicine interventions.

OBJECTIVE

To address this gap in research, this study aims to conduct a systematic review to describe the WTP for telemedicine interventions and to identify the factors influencing WTP among patients with chronic diseases in high-income settings.

METHODS

We systematically searched 4 databases (PubMed, PsycINFO, Embase, and EconLit). A total of 2 authors were involved in the appraisal. Studies were included if they reported the WTP amounts or identified the factors associated with patients’ WTP, involved patients aged ≥18 years who were diagnosed with chronic diseases, and were from high-income settings.

RESULTS

A total of 11 studies from 7 countries met this study’s inclusion criteria. The proportion of people willing to pay for telemedicine ranged from 19% to 70% across the studies, whereas the values for WTP amounts ranged from US $0.89 to US $821.25. We found a statistically significant correlation of age and distance to a preferred health facility with the WTP for telemedicine. Higher age was associated with a lower WTP, whereas longer travel distance was associated with a higher WTP.

CONCLUSIONS

On the basis of our findings, the following are recommendations that may enhance the WTP: exposure to the telemedicine intervention before assessing the WTP, the lowering of telemedicine costs, and the provision of patient education to raise awareness on telemedicine’s benefits and address patients’ concerns. In addition, we recommend that future research be directed at standardizing the reporting of WTP studies with the adoption of a common metric for WTP amounts, which may facilitate the generalization of findings and effect estimates.

Curently, numerous rice yellow stunt disease symptoms are found in the field that caused by the single and simultaneous infection of these two viruses. Brown plant hopper population correlate with the incidence and severity of the disease. Misuse of insecticides, would cause of BPH resistances to imidacloprid. This study aimed to investigate the ability of BPH imidacloprid-resistant and susceptible to transmit of rice yellow stunt disease on rice plants. The variables tested were the acquisition period, inoculation period, number of infesting BPH, and lifespans of the viruliferous BPH that used in this research. Experiments were set as separated Completely Randomized Design with 10 replications for each treatment within an experiment. The results showed that both resistant and susceptible BPH to imidacloprid was able to transmit the virus to healthy plants. The acquisition and inoculation period test showed the BPH could transmit the virus with the shortest acquisition time for 30 minutes followed 24 hours of inoculation, as well as the acquisition time of 10 days with the shortest inoculation time for 30 minutes. Based on the incubation time, symptoms variation, and disease severity, susceptible BPH were more effective in transmitting rice yellow stunt disease than imidacloprid-resistant BPH. Single imidacloprid-resistant  or susceptible BPH was proven able to transmit rice yellow stunt disease to healthy plants during its lifespan. Lifespans BPH viruliferous of imidacloprid-resistant were shorter than susceptible, which was 16 days for resistant BPH and 21 days for susceptible BPH.

Viruses have been a problem on garlic cultivations in various countries. There are several viruses reported infecting garlic. Genera Potyvirus and Carlavirus are the most common viruses found infecting garlic. Mixed infection on garlic is often designated as a “garlic viral complex”. These viruses can be transmitted through imported garlic seeds. Therefore, it is necessary to conduct early detection of garlic seeds to prevent the epidemic of these viruses. This study aimed to detect Onion yellow dwarf virus (OYDV) and Shallot latent virus (SLV) on garlic. Garlic samples were obtained from Enrekang, Magelang, Temanggung, Tawangmangu, and Yogyakarta. Total RNA was extracted from the samples and subsequently used for RT-PCR using two pairs of specific primers SLV-F/SLV-R and OYDV-F/OYDV-R. Primary pair SLV-F/SLV-R in amplicons sized 276 bp, while OYDV-F/OYDV-R in amplicons sized 112 bp. RT-PCR results showed that OYDV was found in all samples tested in this study. Meanwhile, double infections (OYDV and SLV) were found in eight out of ten samples tested. These results indicated that double infections on garlic were common in Indonesia.

Abstract: Mulching has long been used to conserve soil moisture, manage weeds, modify soil temperature, and create a microclimate for plants. There are a variety of strategies for improving crop growing conditions, including increasing productivity and reducing the amount of water necessary to grow the crops. However, mulching paper, also known as agricultural film, is one of the most effective ways to cover the soil and keep the crop in the right environment This mulching paper comes in a varietyof varieties, but because plastic mulching is well-known for requiring less effort, we've chosen to work on an automatic mulching paper laying machine that also includes a drip laying attachment. Moisture in the soil is critical for crop survival in arid environments. Mulching with plastic paper film around theroot area of plants prevents weed growth while also storing water and preventing soil dehydration, however this method takes a lot of money and time. So the 'Mulching paper laying machine with hole punching' will save money and time because it will handle both chores at once, laying mulching paper and punching holes in the ground. A body, a mainframe with hoeing blades, hole punching wheels, drip role holder, and punching mechanism make up the plastic mulch laying machine. The mulch was laid on the prepared plantation bed by the machine in conjunction with the drip pipe. This will lay mulch onthe bed without destroying it, as well as punch the holes to the desired dimensions. The product might be used in agriculture to grow tomatoes, watermelons, muskmelons, and other hybrid varieties of crops. Bylowering the capital cost and time of laying the mulching paper using the most convenient way, as well as installing the drip irrigation pipe in one pass of the machine, it will be simple for the farmer.

This research aims to describe the attitudes in preventing the spread of Covid-19 of the villagers of Gampong Lampuuk and Gampong Cot Suruy, Aceh Besar. It uses a case study of the qualitative approach. Data is collected by using observation and interview techniques and analyzed by using the thematic technique. There are positive responses from the community who received counseling on the prevention of Covid-19, although the level of public concern about Covid-19 was low due to the distrust of the existence of the Corona virus. Followed the World Health Organization (WHO) declaration of the existence of Covid-19 as a pandemic on March 11, 2020, The Indonesian government issued some regulations related to preventing the spread of Covid-19. The realization of each regulation involves the central government, local government, head of the villagers, and the whole society. Specifically, The head of the villagers (Geuchik) and health workers mobilize outreach activities to prevent the pandemic. In fact, not all people are willing to apply health protocols for preventing the spread of the disease.

The government is expected to develop a public service paradigm from a centralized service to a service that focuses more on community satisfaction-oriented management. Moreover, the village apparatus (gampong in Acehnese language) as part of the state apparatus has a direct relationship so that they should better understand the living conditions of the people who are within the scope of their administration. In this case, the author takes a case study of the Gampong Empee Trieng Government, where the author performed community service tasks. To meet the demands of excellent administrative services, Gampong government officials are required to provide good services, especially in providing professional services, having work systems and service procedures that are transparent, integrated, responsive, and adaptive to any changes. This study uses a descriptive approach with qualitative research that will provide an overview of how the performance of the Gampong Empee Trieng government in improving the quality of public services for its people. The three principles of government administration that focus on public services will be used as indicators to measure the quality of public services in Gampong Empee Trieng, Darul Kamal District, Aceh Besar District.

Heavy metals are naturally occurring elements, but they are regarded as significant environmental pollutants due to their high density and high toxicity even at low concentrations. The aim of this paper is the evaluation of the pollution level of heavy metals in the river and riverbank sediments, as well as the estimation of their origin and spatial differences along the course of the Vrbas River through Banja Luka. The concentrations of metals have been assessed using the Inductively coupled plasma ? optical emission spectrometry and Advanced mercury analyzer for mercury determination. The anthropogenic impact on heavy metal concentration in sediments was estimated by the calculating of pollution indices: geoaccumulation index (Igeo), contamination factor (Cf), pollution load index (PLI) and potential ecological risk index (Er). Obtained results indicate that there is no statistically significant spatial difference in metal concentration, indicating that heavy metals in sediments have a constant source. The anthropogenic impact expressed by the values of pollution indices showed that sites are generally uncontaminated by Co, Cr and V and moderately contaminated by Zn, Cu and Ni. On the contrary, lead, mercury and cadmium pose the highest ecological risk. The anthropogenic source of Pb, Hg and Cd is industry, municipal waste and the combustion of fossil fuels. The obtained results demonstrate the high ecological risk and the need for environmental monitoring, with the aim to support an efficient strategy to reduce local pollution and contamination of the investigated system.

Published: September 2021

Pasaran is the only productive small island functioning as the anchovy and green clam production center in Bandar Lampung. Its water use has, however, increased since its designation as an economically fishery-based development area or minapolitan in 2012. This is due to the fact that groundwater resources in small island ecosystems surrounded by seawaters with a narrow diameter are easily affected by the insistence of seawater. Moreover, population pressure and land-use change are also feared to be affecting groundwater quality. Therefore, this research was conducted to analyze and evaluate groundwater resource quality in Pasaran Island using five wells on the entire island as sampling points selected based on census. The samples were tested for physical, chemical, and biological parameters in the laboratory and compared with water quality standards (Minister of Health’s Regulation No. 32/2007). The results showed relatively low water quality because the samples contained up to 3900 μS/cm salinity, 3771.9 mg/l chlorides, 31.7–141.52 mg/l nitrates, and 6.8–170 MPN/100ml total coliform which exceed the standards for drinking water. Meanwhile, wells 1, 4, and 5 were found to be safe for sanitation-hygiene purposes and well 1 was suitable for public baths even though they are not of drinking quality. This means the groundwater quality generally met Class II-water requirements for clean water supplies.

Stunting has become a global concern. The incidence of stunting in the world contributes to 15% of under-five mortality, with 55 million children losing their health, and it is estimated to reduce the country's GDP level by up to 7%. In Indonesia, the incidence of stunting has become one of the main health problems that need to be solved immediately. Malang Regency is one of the districts in East Java Province that has received the spotlight regarding this problem. This research examined the risk factors of stunting in Malang Regency through Geographically Weighted Regression (GWR). GWR was carried out to calculate the correlation between predetermined demographic, health, and economic variables, which were assumed to influence risk factors of stunting. GWR allocation and model examinations are important in understanding risk factors of stunting in the study of disease transmission in the investigation zone. Based on GWR analysis, the research shows that only four (4) sub-variables were significant: the number of poor people, level of education, number of health facilities, and access to health facilities. We also found that Lawang, Gondanglegi, and Turen districts have high-risk areas to stunting. Therefore, within this study that correlates to government policy to decrease or eliminate stunting incidents, districts belonging to the high-risk class should be prioritized or concerned. Moreover, based on LISA, some districts are affected by the risk factors of stunting from the surrounding districts with higher stunting potential value such as Gondanglegi and Pagelaran Districts.

Pandeglang Regency is an area that has the potentiel to be hit by tsunamis. The plate subduction paths of Indo-Australia and Anak Krakatau Volcano make Pandeglang Regency a region with a high tsunami potential. One step that can be taken to overcome and minimize losses is to do spatial planning to protect it against potential tsunami damage. This research aimed to evaluate the spatial area of Pandeglang Regency based on the identification of potential tsunami hazards.  The concept of modelling the tsunami inundation height developed by Berryman and based on Head Regulation No.4 of 2012 of the Indonesian National Board for Disaster Management has been used to identify potential tsunami hazards. The modelling was carried out by calculating the potential distribution of tsunami wave heights in coastal areas.  Three scenarios were used to estimate the distribution. The results showed that the first scenario predicted a maximum tsunami height   of 7.5 meters above sea level with the furthest tsunami inundation reaching 1,700.12 meters. Second scenario predicted maximum height of 15 meters, with the furthest tsunami inundation reaching 3,384.62 meters. Meanwhile, the last scenario was able to predict a height of 20 meters and showed the furthest tsunami inundation reaching 5.155,11 meters. These results proved that in all scenarios, the widest inundation would occur in Panimbang Regency. This is due to the relatively small variations in roughness and slope of the surface. The same condition also occurs in the last two scenarios, in which Sumur District was the area most ffected. Therefore, the spatial plan of Pandeglang Regency needs to be evaluated and the function of residential area changed to reduce and prevent large losses.
