Published: March 2022

Background: PCGF4 as a cancer stem cells (CSC) marker displays stem cell-like properties, and drug resistance in hepatocellular carcinoma (HCC). PCGF2, a homologue of PCGF4, the effect of PCGF2 on liver CSCs (LCSCs) and drug resistance and the molecular mechanism of this effect have not been documented.Methods: To measure the cell viability, CSCs properties of the cells, the Cell Counting Kit-8, spheroid assay, and flow cytometry assays were applied in the HCC cell lines, respectively. The self-renewal was determined by limiting dilution assay. Also, IHC and western blotting were used to detect protein expression of PCGF2 and PCGF4 in human HCC tissues, cell lines and the effects of PCGF2 overexpression on the p38 MAPK genes expression. Kaplan-Meier curves were generated for overall survival (OS) and disease-free survival (DFS). We performed KEGG analysis on target genes through the R language cluster profiler package.Results: IHC showed that expression of PCGF4 and PCGF2 correlate inversely in HCC cell lines and HCC tumors. Overexpression of PCGF2 inhibited the stemness of HCC cells refected by decreasing sphere-forming and self-renewal capacities as well as the expression of CSCs markers. Interestingly, down-regulating PCGF4 led to similar results as up-regulating PCGF2. We also found that PCGF2 and PCGF4 oppositely regulated the stem-like properties driven by the p38 MAPK signalling pathway.Conclusion: Our results suggest that PCGF2 inhibits the stem cell population, reduces the sphere formation ability in HCC cell lines, and increases sensitivity to sorafenib by targeting p38 MAPK signalling.

Published: March 2022

Background: To investigate the differential contribution of the left atrial (LA) function and left ventricular (LV) fibrosis to pulmonary arterial systolic pressure (PASP) in hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM) and reperfused acute myocardial infarction (AMI). Methods: Data of 370 patients with HCM (n=133), DCM (n=114) and reperfused AMI (n=123) who underwent both echocardiography and cardiovascular magnetic resonance (CMR) were comprehensively reviewed. Phasic LA volumes, LA-global longitudinal strain (GLS), and extracellular volume fraction (ECV) of LV were measured using CMR. Results E/e’ was correlated with PASP in all groups; however, the predicted value was significantly attenuated after adjusting for LA volume and LA strain in HCM and DCM, but remained significant in AMI. The E/e’/LA-GLS was related to PASP in HCM (p=0.01) and DCM (p=0.03) independent of LA volume index and E/e', but not in AMI. In DCM, ECV was significantly related to PASP (p<0.001) independent of LA volume index and E/e’. When subdivided according to the linear regression between PASP and E/e’, patients in the discrepantly high PASP group had lower total emptying fraction and reservoir fraction of left atrium in HCM and DCM but not in AMI. Conclusions: The LA function in HCM and DCM and LV fibrosis in DCM correlated with PASP independent of E/e’ and LA size, contrary to that in AMI. These results suggest the presence of atrial myopathy in non-ischemic cardiomyopathies and usefulness of ECV measurement in DCM for the comprehensive evaluation of LV diastolic function.
A novel background field approach to the confinement-deconfinement transition
Authors: van Egmond Duifje Maria , Reinosa Urko , Serreau Julien , Tissier Matthieu
Published: March 2022

We propose a novel approach to the confinement-deconfinement transition
in Yang-Mills theories in the context of gauge-fixed calculations. The method is based on a background-field generalisation of the Landau gauge (to which it reduces at vanishing temperature) with a given, center-symmetric background. This is to be contrasted with most implementations of background field methods in gauge theories, where one uses a variable, self-consistent background. Our proposal is a bona fide gauge fixing that can easily be implemented on the lattice and in continuum approaches. The resulting gauge-fixed action explicitly exhibits the center symmetry of the nonzero temperature theory that controls the confinement-deconfinement transition. We show that, in that gauge, the electric susceptibility diverges at a second order transition [e.g., in the SU(2) theory], so that the gluon propagator is a clear probe of the transition. We implement our proposal in the perturbative Curci-Ferrari model, known for its successful description of various infrared aspects of Yang-Mills theories,
including the confinement-deconfinement transition. Our one-loop
calculation confirms our general expectation for the susceptibility
while providing transition temperatures in excellent agreement with the
SU(2) and SU(3) lattice values. Finally, the Polyakov loops above the
transition show a more moderate rise, in contrast to previous
implementations of the Curci-Ferrari model using a self-consistent
background, and our SU(3) result agrees quite well with the lattice data
in the range [0,2T_c][0,2Tc].

A Structure-Function Analysis of DNA Topoisomerase II Inhibitors
Authors: lnsaf Shabana S. , Danks Mary K. , Witiak Donald T.
Published: March 2022

DNA topoisomerases are ubiquitous enzymes that catalyze the interconversion of different topological forms of DNA. Topoisomerases are expressed at higher levels in logarithmically growing cells than in quiescent cells. Possibly, this enables differentiation between cancer and normal cells making this enzyme an attractive target for therapeutic intervention. Different types of topoisomerases, the mechanism of interconversion of DNA topological states, and structural requirements for cytotoxic poisons and catalytic inhibitors of these enzymes are discussed. lntercalative and non-intercalative cleavage complex poisons as well as the direct catalytic inhibitors provide for at least three different molecular modes of action, but future research is certain to show that additional mechanistic subdivions will be necessary to more completely characterize the cytotoxic mechanisms of these drugs.
Dysexecutive Alzheimer’s Disease with Lewy Body Disease Co-Pathology
Authors: Coburn Ryan P. , Botha Hugo , Graff-Radford Jonathan , Reichard R. Ross , Jones David T. , Ramanan Vijay K.
Published: March 2022

Background:

Alzheimer’s disease can present atypically as a progressive dysexecutive
syndrome (dAD), an entity that preferentially affects younger individuals and is frequently misdiagnosed,
highlighting the imperative for additional research.

Objective:

The objective of this study is to characterize the clinical, antemortem neuroimaging, and
postmortem neuropathologic features of two cases of young-onset dAD who displayed evidence of
Lewy body disease (LBD) co-pathology at autopsy.

Methods:

Clinical histories, antemortem MRI and PET imaging, and postmortem neuropathologic
data were reviewed for each patient.

Case Descriptions/Results:

Canonical features of dAD were observed in both cases, including progressive
and predominant impairment in tasks related to working memory and cognitive flexibility, a
lack of major behavioral/personality changes, and evidence of abnormal amyloid and tau deposition by
antemortem amyloid and tau PET and postmortem neuropathology. Relative sparing of hippocampal
involvement was observed in both individuals, in keeping with many cases of clinically atypical AD.
One of the patients developed subtle parkinsonian signs as well as paranoia and irritability in the years
prior to passing. In both cases, transitional (brainstem and limbic) LBD co-pathology was observed at
autopsy.

Discussion:

Although LBD co-pathology is not uncommon in AD overall, the presence of LBD pathology
in these young-onset cases of dAD (including a case with apparent symptomatic correlate)
warrants further investigation for broader frequency and underlying pathophysiology.

Conclusion:

A better understanding of which specific young-onset AD phenotypes are associated with
LBD co-pathology would have important implications for counseling, treatment, clinical trial enrollment,
and knowledge on disease mechanisms.

Published: March 2022

Background and Objective:

Differentiating non-small cell lung cancer (NSCLC) from
small cell lung cancer (SCLC) remains a substantial challenge. This study aimed at evaluating the performance
of dual-layer spectral detector CT (DLCT) in differentiating NSCLC from SCLC.

Methods:

Spectral images of 247 cancer patients confirmed by pathology were retrospectively analyzed
in both the arterial phase (AP) and the venous phase (VP), including 197 cases of NSCLC and 50
cases of SCLC. Effective atomic number (Z-eff), Spectral CT-Mono Energetic (MonoE
[40keV~90keV]), iodine density (ID) and thoracic aorta iodine density (IDaorta) in contrast-enhanced
images were measured and compared between the SCLC and NSCLC subgroups of tumors. The slope
of the spectral curve (λ, interval of 10 keV) and normalized iodine density (NID) were also calculated
between the SCLC and NSCLC. Through the statistical analysis, the diagnostic efficiency of each
spectral parameter was calculated, and the difference in their efficiency was analyzed.

Results:

Both in NSCLS and SCLC, all parameters in VP were significantly higher than those in AP
(p<0.001), except for λ90. There were significant differences in all spectral parameters between
NSCLS and SCLC, both in AP and VP (p < 0.001). Except for VP-λ90, there was no significant difference
in ROC curves of all spectral parameters. VP-NID exhibited the best diagnostic performance with
an AUC value of 0.917 (95%[CI]: 0.870~0.965), sensitivity and specificity of 92.9% and 80%, and a
diagnostic threshold of 0.217.

Conclusion:

All parameters of DLCT have high diagnostic efficiency in differentiating NSCLC from
SCLC except for VP-λ90, and VP-NID has the highest diagnostic efficiency.

Authors: Zhang Huaizhong , Peng Xuyang , Wu Xuhui , Wu Gongzhi , Peng Chongxiong , Huang Bin , Huang Mingjiang , Ding Jianyang , Mao Chaofan
Published: March 2022

Purpose:

The study aims to explore the regulatory mechanism of miR-129-2-3p underly-ing esophageal carcinoma (EC) cell progression and generate new ideas for targeted treatment of EC.

Methods:

Mature miRNA expression data and total RNA sequencing data of EC in the TCGA-ESCA dataset were utilized to explore differentially expressed miRNAs (DEmiRNAs). StarBase da-tabase was then utilized to predict targets of miRNA. MiR-129-2-3p and DNMT3B expression in EC cell lines was assayed through qRT-PCR and Western blot. CCK-8, scratch healing, and transwell assays were conducted to assess the impact of miR-129-2-3p on EC cell phenotypes. In addition, a dual-luciferase assay was completed to identify the binding relationship between DNMT3B and miR-129-2-3p.

Results:

MiR-129-2-3p was noticeably less expressed in EC cell lines, while DNMT3B was highly expressed. MiR-129-2-3p could bind to DNMT3B. Furthermore, in vitro functional experiments un-covered that overexpressed miR-129-2-3p repressed EC cell progression while further overexpress-ing DNMT3B would restore the above inhibitory effect.

Conclution:

MiR-129-2-3p is a cancer repressor in EC cells, and it could target DNMT3B, thus hampering the progression of EC cells.
Have public policy and family farming been an unhappy marriage for the past 20 years?
Authors: Roa-Ortiz Santiago Andrés , Forero Camacho Cesar Augusto , Bautista Cubillos Roger Alonso , Zabala Perilla Andrés Felipe
Published: March 2022

The countries of Latin America and the Caribbean (LAC) have made progress in creating and implementing public policies on family farming (FF) by developing their own concepts, which converge in the fact that the family labor force is the most important link. However, this also appears to be their weakness for the future, since the exodus from the countryside to the city is affecting work in this sector, and restrictive policies in this regard could end up denying the resources needed for FF to achieve greater development. This document aims to review the existing policies, official figures, and regulations that have been created over the years to recognize and strengthen family farming (FF) in Latin America and the Caribbean (LAC). To achieve our goals, we carried out a systematic search for technical documents (books, reports, and papers with official figures), policies, and legislation related to FF in LAC. Several countries have developed concepts to make policies focused on family farmers. Nonetheless, all converge in that the family workforce is the most critical link in this conceptualization. However, it also seems to be its Achilles’ heel for the future since the field-city exodus is affecting this sector, and restrictive policies could reduce the necessary resources for FF to achieve more significant development. Furthermore, the most significant challenges are found in conducting research on crops and animal species that mainly affect FF, such as corn, beans, rice, cassava, vegetables, cattle, sheep, goats, pigs, and milk. Finally, efforts need to focus on studying changes in family composition, the quality of land, the role of family farmers as guardians of ancestral and native crops, excluding FF export crops. Unpaid women must not be forgotten as a vital part of FF because domestic and production units are closely related.
Social Media for ImpLementing Evidence (SMILE): Conceptual Framework
Authors: Zhao Junqiang , Harvey Gillian , Vandyk Amanda , Gifford Wendy
Published: March 2022

Background

Social media has become widely used by individual researchers and professional organizations to translate research evidence into health care practice. Despite its increasing popularity, few social media initiatives consider the theoretical perspectives of how social media works as a knowledge translation strategy to affect research use.

Objective

The purpose of this paper is to propose a conceptual framework to understand how social media works as a knowledge translation strategy for health care providers, policy makers, and patients to inform their health care decision-making.

Methods

We developed this framework using an integrative approach that first involved reviewing 5 long-standing social media initiatives. We then drafted the initial framework using a deductive approach by referring to 5 theories on social media studies and knowledge translation. A total of 58 empirical studies on factors that influenced the use of social media and its messages and strategies for promoting the use of research evidence via social media were further integrated to substantiate and fine-tune our initial framework. Through an iterative process, we developed the Social Media for ImpLementing Evidence (SMILE) framework.

Results

The SMILE framework has six key constructs: developers, messages and delivery strategies, recipients, context, triggers, and outcomes. For social media to effectively enable recipients to use research evidence in their decision-making, the framework proposes that social media content developers respond to target recipients’ needs and context and develop relevant messages and appropriate delivery strategies. The recipients’ use of social media messages is influenced by the virtual–technical, individual, organizational, and system contexts and can be activated by three types of triggers: sparks, facilitators, and signals.

Conclusions

The SMILE framework maps the factors that are hypothesized to influence the use of social media messages by recipients and offers a heuristic device for social media content developers to create interventions for promoting the use of evidence in health care decision-making. Empirical studies are now needed to test the propositions of this framework.

Wayang Kulit Tradisional dan Pasca-Tradisional di Jawa Masa Kini
Authors: Cohen Matthew Isaac
Published: March 2022

Regional traditions of wayang kulit puppetry remain alive and vibrant in contemporary Indonesia, responding to currents of global culture, changing configurations of patronage, and the challenges of doctrinal Islam. Enterprising artists tap into new funding sources to renew audiences, strategic alliances are struck between academics and performers, and after the long hiatus of a military dictatorship under President Soeharto, wayang kulit has resumed its role as a mouthpiece for political commentary and dissent. In addition to traditional wayang kulit, the last decade has seen a surge of post-traditional wayang kulit. Post-traditional productions, which are generally not linked to ritual events or functions, etiolate and hybridize the conventions of the form, intentionally violating sacred norms and taboos. Traditionally-trained practitioners alive to global popular culture and the demands of the international contemporary art market, sometimes in collaboration with other artists, create new work that draws deeply on wayang kulit conventions and practices to speak to new audiences about issues of current relevance. While traditional and post-traditional wayang kulit present strikingly different aesthetic profiles, practitioners happily cross between the two art worlds, benefiting from contemporary society’s cultural pluralism.

Social media has become more critical for people to communicate about the pandemic of COVID-19. In social media, hashtags are social annotations which often used to denote message content. It serves as an intuitive and flexible tool for making huge collections of posts searchable on Twitter. Through practices of hashtagging, user representations of a given post also become connected. This study aimed to analyze the hashtag of Indonesian COVID-19 Tweets using Social Network Analysis (SNA). We used SNA techniques to visualize network models and measure some centrality to find the most influential hashtag in the network. We collected and analyzed 500.000 public tweets from Twitter based on COVID-19 keywords. Based on the centrality measurement result, the hashtag #corona is a hashtag with the most connection with other hashtags. The hashtag #COVID19 is the hashtag that is most closely related to all other hashtags. The hashtag #corona is the hashtag that most acts as a bridge that can control the flow of information related to COVID-19. The hashtag #coronavirus is the most important of hashtags based on their link. Our study also found that the hashtag #covid19 and #wabah have a substantial relationship with religious-related hashtags based on network visualization.

The bin packing problem is a problem where goods with different volumes and dimensions are put into a container so that the volume of goods inserted is maximized. The problem of multi-objective bin packing is a problem that is more commonly found in everyday life, because what is considered in packing is usually not only volume.In this research, a multi-objective genetic algorithm is proposed to solve the multi-objective bin packing problem. The proposed genetic algorithm uses non-dominated sorting and crowding distance methods to get the best solution for each objective and to avoid bias. The algorithm is then tested with several test classes that represent different combinations of item and container sizes.From the results of the tests carried out, it was found that the proposed algorithm can find several solutions which are the best candidate solutions for each objective.

Decision Support System to Prioritize Ventilators for COVID-19 Patients using AHP, Interpolation, and SAW
Authors: Prasetyo Nikolas Adhi , Wardoyo Retantyo
Published: March 2022

Ventilator shortages is a common problem faced by hospitals during the COVID-19 pandemic era. Healthcare workers are forced to make choices because of how big the difference between resources and lives needing it. This issue rarely comes, because normally every patient has the same rights to receive treatment and resources, but it becomes a clear problem when there are barely enough resources. Therefore, a prioritization mechanism that can objectively decide the allocation must be made to achieve the best outcome.A decision support system is a system that can support humans using data as decision makers to help them decide semi-structured/unstructured problems. The goal of this research is to create a DSS to prioritize patients who need a ventilator by incorporating two different methods, which are AHP, Interpolation, and SAW. It is hoped that the result of the research can be used to rank patients based on predetermined criterias and policy.

Calculation of wet areas carried out with the help of millimeter block paper has the disadvantage of copying the edges that are less precise and the calculation time is quite long. Another problem is the consistency and accuracy that is generated depends on the subjective factors of the person and one's fatigue. In order for the process to be faster and more consistent, the calculation process using image processing is very necessary. Image preprocessing includes cropping, grayscalling, lowpass filter averaging, convertion to binary image based on otsu thresholding, and complementing images to pixel objects of value 1. Segmentation with morphological operations, including opening operations to remove small objects around objects, Holes Filling operations to fill holes in objects, opening operations again to remove objects other than wet areas. The process of calculating wet areas uses chain code. Based on the results of testing of 81 images, the use of morphological operations is able to produce segmentation of wet areas that approach the original wet area. The scale value affects the accuracy and the best scale is obtained from the use of the ruler. The use of chain code is able to calculate the wet area on filter paper with an average accuracy of 95.73%, the value is higher than extensive use by summing the pixel value even though it is not significant. The average calculation of wet areas uses a system of about 0.8 seconds or 379 times faster than using millimeter block.

Efisiensi Daya Pada Smartlock Bike-Sharing Berbasis LoRaWAN Dengan Metode GPS Duty Cycle
Authors: Nugroho Alfian Andi , Ashari Ahmad
Published: March 2022

Bike-sharing or commonly called Public-Use Bycycle (PUB), Bycycle Transit, or Smartbike is a short-term bicycle rental system that allows users to borrow bikes from a self-serve bike-sharing station to a point. Due to technological advances, the bike-sharing system that was once simple, now also utilizes technology in its operations. The modern bike-sharing system is equipped with IoT and GPS technology that is useful for sending data on the actual location of the bicycle, bicycle lock conditions, or even for M2M communication with other stations or bikes. However, this data transmission can cause the battery to run out quickly because of frequent sending and using GSM which requires a large enough power that is 200 mA when sending data and 80 mA when receiving, so that an alternative solution is needed to be able to save power. Therefore, the GPS Duty cycle is used as a method to increase power efficiency on the smartlock. In addition to using the GPS Duty cycle, this study also uses LoRa as a data delivery medium which has lower power usage compared to GSM technology. The results of this study are the duty-cycle algorithm can increase the efficiency of power usage up to 59% when compared to smartlocks that do not use the duty-cycle algorithm. It was also found that LoRa succeeded in sending data up to a distance of 750 meters with a successful delivery of 39.3 percent

Pre-processing is done to visualize radar data from Yogyakarta Climatology Station into a two-dimensional image. After capturing features using the RGB and HSV methods and labeling the rain class, classification is performed using the Neuro-fuzzy algorithm with the Adaptive Neuro-fuzzy Inference System (ANFIS) architecture. The results showed that the Neuro-fuzzy System algorithm was able to classify rainfall better on the RGB feature with an accuracy of 85.02% and a precision of 86.19%, while for the HSV feature the accuracy was 82.68%, 86.67% precision.

Blood type in the medical world can be divided into 4 groups, namely A, B, AB and O. To be able to find out the blood type, a blood type test must be done. So far, human blood type detection is still done manually to observe the agglutination process. This research applies a blood type identification process using image processing. This system works by reading the blood type card image that has been filled with blood samples, then it will be processed through a histogram process to get the minimum and maximum RGB values and pixel locations which are then classified by Artificial Neural Networks (ANN) to determine the blood type from the training results and data matching. From the test results using 12 samples, it was found that the average error in blood type identification was 16.67%.

Plot Sebagai Penjelasan Sejarah: Perihal Kembalinya Arjuna dari Kematian atau Hilangnya

Arjuna died. He was accidentally killed by Prabu Suteja. There was a war between Prabu Suteja and Raden Purwagada, sons of Prabu Kresna. In its next few scenes, Arjuna is revived and appears in Dwarawati Kingdom’s scene without any explanation. It is narrated in a play entitled Kresna Adu Jago by Ki H. Anom Rusdi from Cirebon. Arjuna disappeared since the war between Prabu Kresna and Dewi Pertiwi’s son Bomanerakasura and Samba the son of Prabu Kresna and Dewi Jembawati. Punakawan reported that Arjuna had died in the war. Arjuna and punakawan were both vanished while Arjuna actually lives as an ascetic in Mintaraga cave and later be called as Begawan Ciptaning Mintaraga. Arjuna as Begawan Ciptaning Mintaraga appears in Mintaraga play by Ki Timbul Hadiprayitno from Yogyakarta. Kresna Adu Jago and Mintaraga plays are not identical. Names of the involved characters are different though problems within both plays are similar: a war between sons of Kresna which exacerbates the next problem. The next problem in Kresna Adu Jago is Nerakasura’s grudge against the death of his father, Prabu Suteja, which makes him face Gatutkaca and meet the same fate: died in Gatutkaca’s hands. Problem in Mintaraga is liberation efforts of Dewi Supraba in avoiding Prabu Nirbita Niwatakaca’s intention to marry the angel. Both plays appear identical only on matters of Arjuna’s death, disappearance, as well as his reappearance. Arjuna’s reappearance have the most important difference: Arjuna’s reappearance in Kresna Adu Jago is without reason while it has reasons in Mintaraga. In theories of plot, this cause-effect or effect-cause patterns (instead of a time-based sequence) are called plot. In historical theories, this cause-effect interaction, rather than a sequence of events based on the background of time, is referred to as historical explanation. Through theories of plot, Arjuna’s death in Kresna Adu Jago is a muted history. Through historical theories, Arjuna’s reappearance in Mintaraga is a forged history. Both ways of telling, as options of storytelling, are equally valuable as aesthetic strategies.
Rhoma Irama: Konstruksi dan Reproduksi Tubuh Sang Raja Dangdut
Authors: Raditya Michael H.B.
Published: March 2022

This article deals with the relationship between construction and reproduction in dangdut music, particularly Rhoma Irama. The impact of Rhoma Irama's dangdut construction stimulates the reproduction space of listeners with various creativity through the medium of the body. Power became the main capital in perpetuating construction and reproducing the figure of Rhoma Irama. I would like to discuss the 'fake' body or fake singer phenomena to read construction and body relations. In my opinion, the phenomenon of the fake body in music practice is not just a fandom pattern or for purely economic reasons, but an intertwined form of construction and power. This reproduction makes the construction scheme even more attractive. To disclose the problem, I refer to Michel Foucault for power relations in discussing this practice. This article uses a literature study and ethnography to provide a holistic analysis of the constellation of culture through musical practice. The findings of this article articulate the pattern and power negotiation between Rhoma Irama and the agents—such as listeners, fans, or other dangdut musicians. This article provides an important concern for body reading in the anthropological world of popular music. Artikel ini membahas relasi antara konstruksi dan reproduksi dalam musik dangdut, khususnya merujuk pada Rhoma Irama. Secara lebih lanjut, dampak konstruksi dangdut Rhoma Irama yang menstimulasi ruang reproduksi dari pendengar dengan beragam kreativitas melalui medium tubuh. Kuasa menjadi modal utama dalam melanggengkan konstruksi dan mereproduksi kembali figur Rhoma Irama. Dengan menautkan beberapa fenomena besar atas tubuh ‘palsu’ atau penyanyi palsu, pembacaan relasi tubuh dan konstruksi menjadi perhatian utama. Bagi saya, fenomena tubuh palsu dalam praktik musik bukan sekedar pola fandom atau guna alasan ekonomi semata, melainkan wujud yang berkelindan atas konstruksi dan kuasa. Pilihan-pilihan reproduksi tersebut lantas membuat skema konstruksi menjadi semakin menarik. Dalam mengartikulasikan relasi tersebut, saya merujuk Michel Foucault atas relasi kuasa dalam membahas praktik tersebut. Dengan menggunakan mix-metode antara studi literatur dan etnografi, artikel ini memberikan satu analisis yang holistik dalam menyingkap konstelasi budaya melalui praktik musik. Temuan dari artikel ini akan mengartikulasikan bahwa alasan reproduksi terjalin karena adanya tarik ulur kuasa antara Rhoma Irama dan pelaku reproduksi—baik pendengar, penggemar, ataupun pelaku musik dangdut lainnya. Artikel ini memberikan satu perhatian penting atas pembacaan tubuh dalam jagad musik populer secara antropologis.
