Published: September 2022

La fuga de corriente y sobrevoltaje son de los problemas más críticos en los sistemas eléctricos y electrónicos, los cuales están relacionados con quejas de clientes, y que se estima representan $ 1,920 millones de dólares en pérdidas anuales. En el presente trabajo se evaluaron la fuga de corriente en dispositivos electrónicos como lo son los capacitores electrolíticos con aplicaciones comerciales, y con especificaciones de 10 µm y 35 V. Dos procesos de envejecido fueron evaluados, el tradicional aplicando voltaje y temperatura, y un nuevo proceso eliminando la temperatura e incrementando el voltaje de operación. La efectividad para cada proceso se evaluó mediante equipos tradicionales de medición de corriente y voltaje. Se utilizaron herramientas estadísticas, como distribución logarítmica normal de 3 parámetros, series de tiempo y diagramas de probabilidad, con la finalidad de analizar los datos obtenidos para cada proceso. Se observó, que la fuga de corriente de ambos procesos es aceptable dentro de los límites de especificación, y para el nuevo proceso los resultados de las pruebas a largo plazo mostraron mayor efectividad
Ansiedad matemática y aprendizaje geométrico: una reflexión acerca de sus implicaciones en el contexto formativo
Authors: Pérez Martínez Roberto Carlos
Published: September 2022

Las matemáticas desempeñan un papel importante en todos los aspectos de la vida, pero la principal contribución de las matemáticas es en el ámbito de la educación. Dada la magnitud del papel de las matemáticas en la transformación de la civilización humana, es una rama de que debe ser dominada por los estudiantes de la escuela secundaria. Sin embargo, las matemáticas se perciben como una de las asignaturas más difíciles de aprender debido a su complejidad y naturaleza abstracta. Es por ello que, el presente artículo, tiene como objetivo desarrollar una reflexión crítica acerca de la influencia de la ansiedad matemática en el aprendizaje geométrico, y sugerir estrategias para limitar la reacción emocional negativa a las matemáticas en el contexto formativo. Se concluye que el concepto de ansiedad por las matemáticas, que afecta considerablemente a los niveles de éxito en matemáticas de los estudiantes, no puede abarcar completamente el tema de la ansiedad por la geometría y que la ansiedad por la geometría puede observarse por separado de la ansiedad por las matemáticas.

Published: September 2022

Kehadiran lembaga keuangan yang memberikan layanan berupa pinjam memimjam uang berbasis technology atau financial technology peer to peer lending (fintech P2P lending) diharapkan menjadi suatu terobosan bagi masyarakat di Indonesia yang belum tersentuh layanan perbankan konvensional. Akan tetapi sejalan dengan perkembangan tersebut, diikuti juga permasalahan hukum yang timbul dari banyaknya fintech P2P lending illegal yang tumbuh dan kehadirannya justru merugikan masyarakat pengguna jasa lembaga keuangan tersebut. Artikel ini merupakan hasil dari penelitian yang berkaitan dengan perlindungan hukum terhadap nasabah Fintech P2P Lending di Indonesia. Penelitian ini menggunakan metode penelitian hukum normatif dan teori yang digunakan untuk mengalisisis kajian ini adalah teori perlindungan hukum. Adapun pendekatan yang digunakan adalah statute approach dan conceptual approach. Hasil kajian menunjukkan bahwa perlindungan hukum terhadap nasabah fintech P2P lending telah cukup diatur, akan tetapi pengaturannya masih bersifat parsial dan tersebar dalam berbagai peraturan perundang-undangan. Kedepan diperlukan pengaturan yang berkaitan dengan perlindungan hukum terhadap nasabah fintech P2P lending, secara komprehensif.
TANGGUNG GUGAT PEMERINTAH TERHADAP PEMBATALAN HASIL TENDER SECARA SEPIHAK
Authors: Hadi Fikri , Gandryani Farina , Indriastuti Dwi Elok
Published: September 2022

Pemerintah dalam rangka mendukung terlaksananya program kerja, maka Pemerintah melaksanakan suatu pengadaan barang dan jasa. Salah satunya yang dilakukan oleh Pemerintah Kota Semarang. Pada akhir 2018, Pemerintah Kota Semarang secara sepihak membatalkan hasil pemenang tender dikarenakan adanya kesalahan penghitungan anggaran. Padahal sejumlah tender telah diterbitkan Surat Penunjukan Penyedia Barang/Jasa. Secara hukum privat, kesepakatan tidak dapat ditarik kembali kecuali atas persetujuan kedua belah pihak. Namun secara hukum publik terdapat larangan untuk melakukan pembelanjaan apabila tidak terdapat anggaran. Oleh sebab itu, artikel ini akan membahas mengenai konsep kontrak yang dilakukan Pemerintah terkait di bidang kontrak pengadaan barang dan jasa serta tanggung gugat Pemerintah Kota Semarang terhadap pembatalan hasil tender. Penelitian ini merupakan penelitian hukum bertipe doktrinal dengan pendekatan konseptual, perundang- undangan dan kasus. Hasil penelitian menunjukkan bahwa kontrak Pemerintah berbeda dengan kontrak privat pada umumnya dikarenakan terikat pada aspek hukum publik (hukum administrasi dan hukum pidana) serta aspek hukum privat. Sehingga dari konsep tersebut dikaitkan dengan kasus di Semarang, pemenang tender yang dirugikan tidak bisa mengajukan gugatan ataupun permohonan ke Peradilan Tata Usaha Negara. Pemenang tender yang dirugikan dapat menggugat Pemerintah melalui peradilan umum berdasarkan konsep tanggung gugat Pemerintah.

Published: September 2022

Kejahatan atau tindak pidana oleh korporasi terhadap pekerja dimungkinkan terjadi mengingat semakin meningkatnya persaingan usaha ditengah menyempitnya lapangan kerja. oleh karenanya penelitian ini dibuat dalam bentuk paper bertujuan untuk mengetahui bentuk tindak pidana oleh korporasi terhadap pekerja dan cara penyelesaiannya. Untuk menjawab permasalahan tersebut, penelitian ini dilakukan dengan cara studi kepustakaan hukum positif terkait ketenagakerjaan melalui logika berpikir deduktif-induktif dan hasil pengamatan yang dilakukan oleh peneliti. Hasil penelitian menunjukkan bahwa bentuk tindak pidana oleh korporasi dikategorikan berupa tindak pidana kejahatan dan pelanggaran sedangkan penyelesaiannya belum dapat menjerat korporasi secara langsung karena tindak pidana oleh korporasi terhadap pekerja merupakan delik aduan yang berpotensi mengakibatkan kerugian yang lebih besar bagi korban tindak pidana, selain itu profesionalitas dan kompetensi penegak hukum dibidang ketenagakerjaan tidak berimbang dengan tingkat kompleksitas tindak pidana serta inkonsistensi peraturan perundang- undangang mengakibatkan sulit terwujudnya penegakan hukum tindak pidana oleh korporasi terhadap pekerja sehingga dibutuhkan terobosan hukum atau cara yang dapat memulihkan hubungan diantara keduanya baik pelaku maupun korban.
THE ELEMENTS OF MAKING: A SOCIAL PRACTICE PERSPECTIVE FOR EVERYDAY CREATORS
Authors: Risner Isabelle , Gauntlett David , Culpepper Mary Kay
Published: September 2022

In contrast to behavioural approaches that attempt to explain creativity, social practice theories commonly emphasize aspects of the material world that shape and reproduce how people engage with them. How might social practice theory clarify how making affects millions of hobbyist creators – and what makes making matter to them? This article examines the theoretical work tying creativity to social practice. It then reports on a project in which small groups of everyday creators in the United Kingdom (n = 95) gathered in workshops to discuss their experiences and opinions regarding the materials, meanings, and competences of making. A model-making research method instigated peer discussion revealing both individual and shared accounts of practice. The data indicated that participants, regardless of practice, experienced creating as an ongoing performance providing many benefits that promote personal and societal transformation. With our graphic iteration of the elements of making, we assert that the meanings these makers attached to their various do-it-yourself practices were underscored by the materials they worked with and the competences they built in creating.

Coronal mass ejections (CMEs) are a prominent contributor to solar system space weather and might have impacted the Sun’s early angular momentum evolution. A signal diagnostic of CMEs on the Sun is coronal dimming: a drop in coronal emission, tied to the mass of the CME, that is the direct result of removing emitting plasma from the corona. We present the results of a coronal dimming analysis of Fe xii 1349 Å and Fe xxi 1354 Å emission from ϵ Eridani (ϵ Eri), a young K2 dwarf, with archival far-ultraviolet observations by the Hubble Space Telescope’s Cosmic Origins Spectrograph. Following a flare in 2015 February, ϵ Eri’s Fe xxi emission declined by 81 ± 5%. Although enticing, a scant 3.8 minutes of preflare observations allows for the possibility that the Fe xxi decline was the decay of an earlier, unseen flare. Dimming nondetections following each of three prominent flares constrain the possible mass of ejected Fe xii-emitting (1 MK) plasma to less than a few × 1015 g. This implies that CMEs ejecting this much or more 1 MK plasma occur less than a few times per day on ϵ Eri. On the Sun, 1015 g CMEs occur once every few days. For ϵ Eri, the mass-loss rate due to CME-ejected 1 MK plasma could be < 0.6

mass-loss rate (wind + CMEs). The order-of-magnitude formalism we developed for these mass estimates can be broadly applied to coronal dimming observations of any star.
A New Census of the 0.2 < z < 3.0 Universe. II. The Star-forming Sequence

Published: September 2022

We use the panchromatic spectral energy distribution (SED)-fitting code Prospector to measure the galaxy logM*–logSFR relationship (the star-forming sequence) across 0.2 < z < 3.0 using the COSMOS-2015 and 3D-HST UV-IR photometric catalogs. We demonstrate that the chosen method of identifying star-forming galaxies introduces a systematic uncertainty in the inferred normalization and width of the star-forming sequence, peaking for massive galaxies at ∼0.5 and ∼0.2 dex, respectively. To avoid this systematic, we instead parameterize the density of the full galaxy population in the logM*–logSFR–redshift plane using a flexible neural network known as a normalizing flow. The resulting star-forming sequence has a low-mass slope near unity and a much flatter slope at higher masses, with a normalization 0.2–0.5 dex lower than typical inferences in the literature. We show this difference is due to the sophistication of the Prospector stellar populations modeling: the nonparametric star formation histories naturally produce higher masses while the combination of individualized metallicity, dust, and star formation history constraints produce lower star formation rates (SFRs) than typical UV+IR formulae. We introduce a simple formalism to understand the difference between SFRs inferred from SED fitting and standard template-based approaches such as UV+IR SFRs. Finally, we demonstrate the inferred star-forming sequence is consistent with predictions from theoretical models of galaxy formation, resolving a long-standing ∼ 0.2–0.5 dex offset with observations at 0.5 < z < 3.

Switchbacks are localized deviations from the nominal Parker spiral field in the solar wind. In this study, we investigate the electron distributions inside switchbacks, focusing primarily on the suprathermal (halo and strahl) populations. We explore electron parameters in relation to the angle of rotation of the magnetic field from radial to determine whether electron distributions observed within switchbacks have any differences from those outside of switchbacks. Our observations reveal several trends in the suprathermal electron populations inside switchbacks. We find that the sunward deficit in the electron velocity distribution function typically observed near the Sun is filled in at larger rotation angles. This results in the suprathermal electron density and heat flux in the antistrahl direction changing from a negative to a positive value. On many days, we also observe a positive correlation between the halo density and rotation angle, and this may suggest that the growth of the halo may fill in the sunward deficit. We also find that strahl distributions have an increased average angular spread at large magnetic field rotation angles. The increase in suprathermal electron flux in the antistrahl direction, and the increase in strahl width, together could suggest that enhanced scattering occurs inside switchbacks. Electron core beta values tend to increase with the magnetic field rotation angle, mainly due to a decrease in magnetic pressure. An increase in electron beta may favor the growth of instabilities inside switchbacks. The Parker Solar Probe observations therefore support an enhanced role for wave–particle interactions in switchbacks.

Published: September 2022

We present ALMA observations of CO J = 2 − 1 and CS J = 5 − 4 emission from the disk around TW Hydrae. Both molecules trace a predominantly Keplerian velocity structure, although a slowing of the rotation velocity is detected at the outer edge of the disk beyond ≈140 au in CO emission. This was attributed to the enhanced pressure support from the gas density taper near the outer edge of the disk. Subtraction of an azimuthally symmetric background velocity structure reveals localized deviations in the gas kinematics traced by each of the molecules. Both CO and CS exhibit a “Doppler flip” feature, centered nearly along the minor axis of the disk (PA ∼ 60°) at a radius of 1.″35, coinciding with the large gap observed in scattered light and mm continuum. In addition, the CO emission, both through changes in intensity and its kinematics, traces a tightly wound spiral, previously seen with higher-frequency CO J = 3 − 2 observations. Through comparison with linear models of the spiral wakes generated by embedded planets, we interpret these features in the context of interactions with a Saturn-mass planet within the gap at a position angle of PA = 60°, consistent with the theoretical predictions of Mentiplay et al. The lack of a corresponding spiral in the CS emission is attributed to the strong vertical dependence on the buoyancy spirals, which are believed to only grow in the atmospheric of the disk, rather than those traced by CS emission.

The density inhomogeneity is a typical feature in various magnetoplasmas in the corona, where kinetic Alfvén waves (KAWs) are effectively generated and contribute greatly to the inhomogeneous heating of coronal plasmas. Proton beams exist widely in various space and solar plasma environments. In this paper, based on the kinetic Vlasov theory, we investigate the resonant mode conversion of Alfvén waves to KAWs in the presence of proton beams in an inhomogeneous plasma and the plasma heating of KAWs due to wave−particle interactions. It is found that the wave properties of excited KAWs are highly sensitive to the density of proton beams n

Published: September 2022

The dairy and meat industry has rapidly developed in the last decade in Turkey and is playing a key role in supplying animal proteins for human consumption. Viral pathogens continue to threaten the dairy and meat industry leading to serious economic losses worldwide, including Turkey. The Turkish cattle industry has been vulnerable to the spread of viral diseases within the country in the continent. Combating animal diseases is crucial for the economy of Turkey. A good cattle health management policy may reduce the direct losses associated with viral diseases and thereby lead to increase in export of animals and animal products. Countries that are unable to combat animal diseases remain excluded from international trade. Control and eradication of cattle diseases require the availability of effective and practical interventions including vaccination and biosecurity measures. This review summarises the currently available information about viral diseases in cattle in Turkey and emphasizes the need for disease monitoring and research, along with implementation of disease control measures to mitigate economic losses to farmers and the country. The information presented here can be of great value in the research, prevention, and control of cattle diseases.

Introduction: COVID-19 is a major public health concern in this century. The causative agent SARS-CoV-2, is highly contagious and spreads continuously across territories. Spatial analysis is of enormous importance in the process of understanding the disease and its transmission mechanisms. We aimed to identify the risk areas for COVID-19 and analyze their association with social vulnerability in Maceió, Alagoas. The study was conducted in 2020.
Methodology: This is an ecological study to evaluate the incidence, mortality and case fatality rate of COVID-19 and their relationship with 12 indicators of human development and social vulnerability. Multivariate and spatial statistics were applied. A 95% confidence interval and a 5% confidence level were considered.
Results: The spatial scan statistic revealed the existence of six high-risk clusters for the incidence of COVID-19. The regression model showed that social indicators, such as literacy of people, residents of private households, households with more than four residents, and resident brown population, were associated with COVID-19 transmission in Maceió-AL. The disease affected localities whose populations are exposed to a context of intense socioeconomic vulnerability.
Conclusions: Based on the results, it is necessary to adopt measures that take into account the social determinants of health in order to minimize the damage caused by the pandemic.

Introduction: Schistosoma (S.) haematobium is the aetiological agent of urogenital schistosomiasis endemic in Sub-Saharan Africa and the Middle East. Microhaematuria is strongly associated with schistosomiasis diagnosis. Praziquantel (PZQ) is the treatment of choice.

Methodology: We conducted a monocentric survey among African migrants from January 2017 to December 2018. The diagnosis of S. haematobium was performed by direct microscopic examination of urine. The treatment was PZQ 40 mg/Kg/die for three days.

Results: We enrolled 91 male patients with a median age of 20.2 years (IQR 18.9-23.4)]. Forty-five (49.5%) described a history of haematuria. Sixteen (17.6%) evidenced the presence of red blood cells (RBCs) during urine microscopy. Eighteen (19.8%) had urogenital schistosomiasis. Their median white blood count (WBC) was 5.15 x 109/L (IQR 4.45-6.08) and it was 6.37 x 109 /L (IQR 5.14-8.27), p = 0.009, after 15 days from treatment. Baseline eosinophil count was 0.5 x 109/L (IQR 0.3-0.6) and 0.7 x 109/L (IQR 0.2-1.9; p = 0.032). According to the univariate analysis, origin from Mali [odds ratio (OR) 3.6 (CI 1.2-10.9), p = 0.022] and microscopic evidence of RBCs [OR of 10.7 (CI 2.5-45.1), p = 0.001] were main predictors of urogenital schistosomiasis diagnosis. One (5.6%) treatment failure was registered. Three (16.7%) patients had bladder cancer.

Conclusions: Detection of RBCs was a significant predictor of S. haematobium infection and could be used as a screening method in migrants coming from endemic areas. Early urogenital schistosomiasis diagnosis and ultrasound diagnostic tools are crucial for reducing the risk of potential neoplastic evolution.

Introduction: Vulvovaginal candidiasis (VVC) is a yeast infection of the vulva, which is caused by Candida species and affects women worldwide. Pregnant women are more vulnerable to VVC due to certain risks. Moreover, their offspring are also exposed to the risk of preterm birth. In this context, ascertaining the burden of VVC is of paramount importance and this meta-analysis was conducted to estimate the occurrence of VVC among pregnant women in Africa.

Methodology: Database search was carried out through PubMed, Scopus, Science-Direct, and Google Scholar from the date of inception until December 2020. All the studies on the prevalence of VVC among African pregnant women were included in the analysis. The pooled prevalence was estimated based on the Random-effect model DerSimonian-Laird approach with Freeman- Tukey double arcsine transformed proportion. Heterogeneity was assessed using I2 test and subsequently explored using subgroup and meta-regression analysis.

Results: A total of Sixteen records having a sample size 4,185 were included in this study. The overall prevalence of VVC was pooled at 29.2% (CI 95%: 23.4 – 33.0). Subgroup analysis revealed a higher prevalence in Eastern Africa, followed by Western Africa and North Africa (35%, 28%, and 15% respectively). Moderator analysis indicated that the studies that used advanced methods of detection had a higher prevalence (p = 0.048). In addition, the large sample size was associated with higher prevalence (p ≤ 0.001). No other moderators were found to be statistically significant.

Conclusions: The overall prevalence of VVC among African pregnant women is comparable to other studies worldwide. However, appropriate identification techniques and larger sample size could likely be associated with an increased prevalence. Our findings necessitate the need for further investigations to determine the geographical distribution of VVC across African regions.

Introduction: Since the COVID-19 pandemic began in December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has continuously evolved with many variants of concern emerging across the world.

Methodology: In order to monitor the evolution of these variants in Morocco, we analyzed a total of 2130 genomes of the delta variant circulating around the world. We also included 164 Moroccan delta variant sequences in our analysis.

Results: Our findings suggest at least four introductions from multiple international sources and a rise of a dominant delta sub-lineage AY.33 in Morocco. Moreover, we report three mutations in the N-terminal domain of the S protein specific to the Moroccan AY.33 isolates, T29A, T250I and T299I. The effect of these mutations on the secondary structure and the dynamic behavior of the S protein N-terminal domain was further determined.

Conclusions: We conclude that these mutations might have functional consequences on the S protein of SARS-CoV-2.

Background and objectives: non-pharmacological treatment for depression and anxiety includes a variety of treatments, such as various types of psychotherapy, education, and supporting measures. Behavioral treatments such as progressive muscle relaxation and abdominal breathing exercises have been shown to be effective in the treatment of anxiety and depression in cancer patients. Therefor this study aimed to evaluate the effect of progressive muscle relaxation and abdominal breathing exercise techniques on anxiety and depression among breast cancer patients in Erbil City- Iraq. Methods:  A quasi-experimental study was conducted at Rizgary Teaching Hospital-department of oncology and Nanakali Oncology Hospital at Erbil city-Iraq, Patients from both hospitals were selected as the intervention and control group respectively. Patients were assessed through; the demographic data questionnaire, Hospital anxiety and depression scale. Results: A total of 88 patients 44 from the control group and 44 patients from the study group participated. At the end of the study, there were significant improvements in anxiety and depression (p-value was 0.001) result was observed in both post-tests at 4-week and at 8-week. Conclusion: The women who got progressive muscle relaxation and abdominal breathing exercise techniques had lower anxiety and depression levels than those who only received routine nursing care, according to the findings. Oncology nurses should educate patients with breast cancer to use the progressive muscle relaxation technique to reduce their anxiety and depression. Keywords: Anxiety, Depression, Breast cancer and Relaxation.

Published: September 2022

There is increasing awareness of the need to develop innovative and relevant methodologies to best capture the voices of Young Men Who Have Sex with Men (YMSM), which will inform HIV prevention. This article discusses the process of researching with YMSM in Bali, the solution to methodological gaps in research for Internet-based HIV prevention. This research endorsed the Habermas Communicative Action Theory which was then translated to Participatory Action Research (PAR) methodology. Nine YMSM aged 18-24 years old participated in this research through multiple research activities for four months. Data collection included structured group meetings, group workshops, informal participant observations, and after-hour conversations over afternoon tea and shared meals. Participants used a range of visual and digital media to share their collective ideas and different trial strategies. We argue for the opportunity for participatory action research to strengthen the roles of YMSM in HIV prevention.
Correlation between Platelet Count and Grading of Esophageal Varices in Liver Cirrhosis Patients: A Meta-Analysis
Authors: Baihaqi Fahri Ahmad , Delarosa Dinda Olinda
Published: September 2022

BACKGROUND: Esophageal varices are a major complication of liver cirrhosis. Esophageal varices bleeding is life-threatening and an urgent medical emergency. Low platelet count and esophageal varices are common findings in liver cirrhosis. Platelet count is suggested as a non-invasive screening tool to predict the grading of esophageal varices in liver cirrhosis patients. Several studies have found a correlation between platelet count and grading of esophageal varices in liver cirrhosis patients. However, the results are conflicting.
AIM: This meta-analysis aimed to evaluate the correlation between platelet count and the grading of esophageal varices in liver cirrhosis patients.
METHODS: A systematic literature search was performed through the database search from PubMed, SCOPUS, Ovid EMBASE, and EuropePMC to obtain all relevant articles with the following search terms: "correlation" and "platelet" or "thrombocytopenia" AND "esophageal varices" and "liver cirrhosis" or "chronic liver disease" that were published within the year of 2000-2021. Articles were collected by using PRISMA flow diagrams. The data were extracted from the eligible study within inclusion and exclusion criteria. The quality of each study was assessed using the Newcastle Ottawa Scale (NOS). A meta-analysis was conducted to determine the overall pooled correlation coefficient (r) and 95% confidence interval (CI).
RESULTS: There were a total of 1008 patients from eight included studies. The meta-analysis showed that the pooled correlation coefficient between platelet count and grading of esophageal varices in liver cirrhosis patients was r = -0.42 (95%CI -0.65 to -0.13; p = 0.005; I2 = 96.06%).
CONCLUSION: There was a moderate negative correlation between platelet count and grading of esophageal varices. Thus, low platelet count may indicate higher grades of esophageal varices in liver cirrhosis patients.

Abstract Background:.   labor pain can stress the mother and cause pain impulses to multiply and potentially weaken uterine muscle contractions. Pain can cause distress to the baby. One way to reduce pain is by giving herbal therapy or aromatherapy. Aromatherapy is one of the non-pharmacological methods to reduce labor pain. Aromatherapy often used to reduce labor pain is Lavender, Rose, Jasmine, Citrus Aurantium.   AIM: This study aims to determine the use of herbal therapy to reduce labor pain.The purpose of this study is to analyze the challenges in implementing health education in elementary schools in Banda Aceh   Methods: the design in this study was a literature review article. Search for articles using relevant ones obtained from data based on Pubmed, Proquest, Ebsco, ScienceDirect, and Google Scholar in the past ten years (2011–2021) received 121 articles. Results: The study results show several challenges in implementing health education. Lack of understanding about School Health Services, School Health Services is not considered a strategic program, Low attention from policymakers, School Health Services Program has not been understood as part of the national target, Implementation of UKS program in schools is only a formality, Implementation and development School Health Services program is not evenly distributed. Barriers to the Implementation of School Health Services in  Elementary School are the lack of optimal inter-sectoral cooperation, lack of trained personnel, high workload, and the impact of conflicting health issues, causing various School Health Services activities to be hampered in their Implementation   CONCLUSION: Utilization of herbal therapies such as Lavender, Mawar, Jasmine, Citrus, Aurantium has been proven to reduce labor pain which can be used in various methods such as inhalation, bath, massage, and foot soak. The easy use of aromatherapy can be an alternative to reduce labor pain.
