Authors: Febriani Siti Diah Ayu , Nofitasari Prisca Amalia , Anwar Saiful
Published: September 2023

Biodiesel is an environmentally friendly alternative fuel for diesel engines. The research studies the extraction process of biodiesel from waste produced by a fish canning factory using a heterogeneous catalyst known as cocopeat ash. The experiment was designed utilizing a completely randomized design with two factorial treatments and four repetitions. The primary factor under investigation was the composition of the catalyst, specifically 3%, 5%, and 7% w/v methanol. The second factor examined was the reaction time of either 60 minutes or 120 minutes. Data analysis revealed variations in density, viscosity, acid number, and Free Fatty Acids (FFA) in fish oil before and after refinement. The treatment that yielded the highest results was A3B2, featuring a catalyst composition of 7% and a reaction time duration of two hours, which achieved an impressive biodiesel yield of 81%. Moreover, several parameters tested for compliance with SNI-04-7182-2015 standards showed positive outcomes. These parameters include a density value measuring 876.3 kg/m³, the flash point around 160°C, iodine number reaching 16.36 g/100g, and heating value 47.47 MJ/Kg.

Authors: Twyford Mark , Westby Daniel , Keohane Colum , Tawfick Wael , Walsh Stewart R
Published: September 2023

Background: Intermittent pneumatic compression (IPC) devices apply intermittent compression to the thigh, which is thought to facilitate wound healing by improving wound perfusion in patients with chronic limb-threatening ischemia and no option for revascularization. Wound Express is an IPC device but its safety and efficacy are currently unclear. In this study, we aimed to determine the safety of the Wound Express IPC system in this high-risk cohort.Methods: This was a prospective, non-controlled, non-randomized pilot safety study. In total, 19 patients were screened for inclusion and 10 were recruited. IPC was applied for 2 hours per day for 12 weeks. The primary endpoint was any treatment-related adverse event in the first 3 months. Secondary endpoints included pain using the visual analogue scale, limb status assessed using the Wound, Ischemia, Foot Infection (WIFi) score and quality of life using the Vascular Quality of Life Questionnaire (VASUQOL) score.Results: Of the 10 patients who were enrolled, eight completed the 12-week course. There were no treatment-related adverse events. One patient died from coronavirus disease 19-related disease and two withdrew for reasons unrelated to treatment. Median pain scores were reduced from 6 to 0, while median VASUQOL increased from 10 to 16.5. WIFi scores were reduced in three out of eight of participants (37.5%).Conclusion: Wound Express appears to be safe and may decrease pain, improve wound healing and improve quality of life for chronic limb-threatening ischemia patients. Adequately powered, prospectively randomized trials of the Wound Express system to assess its efficacy and safety are warranted.
Repurposing Rage (or Rage Re-Boot)-- How Audience’s Outrage Supports Generative Processes in Theatre Making
Authors: Nina Marlow
Published: September 2023

This thesis explores process driven creation of new work over five months (April 2023 - August 2023) in Finland. Process included meditation in nature and performances of OUT RAGE, which asked audiences to participate by sharing a concern –outing a rage– with an eco-punk astral messenger. Final products were audience inspired potential products that integrated the overall process, including performance observations and reflections. As a theatre maker with an interest in social and environmental justice, I am invested in creating new work that speaks to the current human condition of our lack of agency on a dying planet. Embracing the certainty of global warming on a human scale, acknowledging anger in society without inciting violence, and then creating new work informed by a collective of participants are at the core of this thesis.

Authors: Luo Jie , Wang Binpan , Tang Xiaoqi , Huang Ping , Yang Sha , Zhao Shuang , Xie Shuang , Li Qiaofeng , Chang Kai , Chen Ming
Published: September 2023

Tumor-derived exosomes are crucial for early non-invasive and accurate
tumor diagnosis in clinical. The development of highly sensitive, simple
and intuitive exosome assays has sparked a research upsurge in clinical
diagnostics. Here, we develop a bio-responsive the intelligent DNA
hydrogel loaded with CRISPR/Cas12a for universal and ultrasensitive
detection of the exosomes. The aptamer serves as the target response
unit and switch of the intelligent DNA hydrogel network. The target
competitively disintegrates the region of the DNA linkers then
Cas12a/crRNA encapsulated in the intelligent DNA hydrogel can be
released and activated by the collateral sequence, resulting in a high
fluorescent intensity for exosome detection at the detection limit of
119 particles/μL. Moreover, a prefabricated colorimetric tube is made by
loading a colorimetric filter membrane on the tube lid and intelligent
DNA hydrogel on the tube bottom, which enables one-pot portable
colorimetric detection. Without the need for laboratory instruments and
professionals, this strategy allows for naked eye detection with LOD as
low as 104 particles/μL, and shows great applicability in distinguishing
between healthy individuals, pretreatment patients, and post treatment
patients after obtaining a testable analyte. Collectively, this study
constructs an ultra-sensitive detection platform for exosomes, which
enables one-step sensing and dual signal output, making it a promising
tool for the application of liquid biopsy based on exosomes in clinical
diagnosis.

Published: September 2023

Soil fungi are involved in the decomposition of organic matter, and they
alter soil structure and physicochemical properties and drive the
material cycle and energy flow in terrestrial ecosystems. Grazing
exclusion is one of the most common measures used to restore degraded
grasslands worldwide. However, changes in soil fungal community
characteristics during grazing exclusion in different types of
grasslands are unknown. Here, we investigated the effects of a 9-year
grazing exclusion on soil properties, fungal community composition and
diversity in three grassland types (temperate desert, temperate steppe
and mountain meadow). The results showed that in the 0-5 cm soil layer,
grazing exclusion significantly affected the physicochemical parameters
of all three studied grassland types. In the 5-10 cm soil layer, grazing
exclusion significantly increased total phosphorus (TP) in temperate
deserts by 34.1%, while significantly decreasing bulk density (BD) by
9.8% and the nitrogen: phosphorus ratio (N:P) by 47.1%. The soil
fungal community composition differed among the grassland types, For
example, significant differences were found among the three grassland
types for the Glomeromycota and Mucoromycota, Grazing exclusion,
grassland type, and the interaction between the two did not
significantly affect soil fungal α-diversity or community composition(P
> 0.05), but significantly altered fungal β-diversity (P
< 0.05). Overall, our results highlight the importance of soil
nutrient content, especially soil Kjeldahl nitrogen, total phosphorus
and organic carbon on fungal diversity, and the results provide key
insights into how soil fungi respond to grazing exclusion in different
grassland types.
Monitoring of physiologic features and treatment aspects of children on home invasive mechanical ventilation"
Authors: Chawla Jasneek , Tan Hui-leng
Published: September 2023

Paediatric home invasive mechanical ventilation patients are a small but
resource intensive cohort, requiring close monitoring and
multidisciplinary care. Patients are often dependent on their ventilator
for life support, with any significant complications such as equipment
failure, tracheostomy blockage, or accidental decannulation becoming
potentially life threatening, if not identified quickly. This review
discusses the indications and variations in practice worldwide, in terms
of models of care, including home care provision, choice of equipment
and monitoring. With advances in technology, optimal monitoring
strategies for home, continue to be debated: In-built ventilator alarms
are often inadequately sensitive for paediatric patients, necessitating
additional external monitoring devices to minimise risk. Pulse oximetry
has been the preferred monitoring modality at home, though in some
special circumstances such as congenital central hypoventilation
syndrome, home carbon dioxide monitoring may be important to consider.
Children should be under regular follow up at specialist respiratory
centres where clinical evaluation, nocturnal oximetry and capnography
monitoring and/or poly(somno)graphy and analysis of ventilator download
data can be performed regularly to monitor progress. Recent exciting
advances in technology, particularly in telemonitoring, which have
potential to hugely benefit this complex group of patients are also
discussed.

Authors: Diaz Juan Carlos , Bastidas Oriana , Duque Mauricio , Marin Jorge , Aristizabal Julian , Niño Cesar , Hoyos-Ochoa Carolina , Matos Carlos D. , Gabr Mohamed , Steiger Nathaniel , Kapur Sunil , Sauer William H. , Romero Jorge
Published: September 2023

Background: Intracardiac echocardiography (ICE) is increasingly
used during left atrial appendage occlusion (LAAO) as an alternative to
transesophageal echocardiography (TEE) Aim: To evaluate the
impact of ICE vs. TEE guidance during LAAO on procedural characteristics
and acute outcomes, as well the presence of peri-device leaks and
residual septal defects during follow-up. Methods: All studies
comparing ICE-guided vs. TEE-guided LAAO were identified. The primary
outcomes were procedural efficacy and occurrence of procedure-related
complications. Secondary outcomes included lab efficiency (defined as a
reduction in in-room time), procedural time, fluoroscopy time, and
presence of peri-device leaks and residual interatrial septal defects
(IASD) during follow-up. Results: Twelve studies (n=5637) were
included. There were no differences in procedural success group (98.3%
vs. 97.8%; OR 0.73, 95% CI 0.42-1.27, p=0.27;
I=0%) or adverse events (4.5% vs. 4.4%; OR
0.81 95% CI 0.56-1.16, p=0.25; I=0%) between
the ICE-guided and TEE-guided groups. ICE guidance reduced in in-room
time (mean-weighted 28.6-minute reduction in in-room time) without
differences in procedural time or fluoroscopy time. There were no
differences in peri-device leak (OR 0.93, 95% CI 0.68-1.27, p=0.64);
however, an increased prevalence of residual IASD was observed with
ICE-guided vs. TEE-guided LAAO (46.3% vs. 34.2%; OR 2.23, 95% CI
1.05-4.75, p=0.04). Conclusion: ICE guidance is associated with
similar procedural efficacy and safety, but could result in improved lab
efficiency (as established by a significant reduction in in-room time).
No differences in the rate of periprocedural leaks were found. A higher
prevalence of residual interatrial septal defects was observed with ICE
guidance.
The Turn of the Twentieth Century and Ikaho Hot Spring Placed at the Beginning ：The Fabricated Bliss in Tokutomi Roka’s Hototogisu
Authors: ANDOH Shiho
Published: September 2023

This paper reappraises Tokutomi Roka’s Hototogisu, a work which was widely presented in a variety of media between the Meiji and Showa periods. Previous studies on this novel have paid attention to its melodramatic structure, which is based on the representation of the Zushi, and the depiction of Takeo reconciling with his late wife Namiko’s father as marking “the end” (owari). However, the Shinpa versions, which were considered to be the most representative of various stage adaptations of Hototogisu, used the hot spring site of Ikaho as the setting for the opening act of the play, as in the original novel. Both the Shinpa adaptations and the original novel entail the link between the Ikaho hot spring and Hototogisu, in this way centering the portrayal of marital bliss. This is also emphasized in collected essays Ikaho Miyage. To elucidate the function of this bliss in the literary works of later generations, this paper revisits the centrality of Ikaho in the original novel while also considering the instability and multiplicity of the 1890s Japanese society from which it emerged. This focus reveals how the image of “hot springs” is conceptualized and the kind of linguistic network that is constructed in Hototogisu.
“Bullying” as a Trap for Solidarity ：An Essay on Shun Medoruma’s Mā No Mita Sora (The Sky as Seen by Ma)
Authors: HATA Kohei
Published: September 2023

In this paper, I read Mā No Mita Sora (The Sky as Seen by Ma), written by Shun Medoruma. Medoruma has been regarded as a author of Okinawa literature. However, in many of Medoruma’s works, “Bullying” is expressed. It is important to consider the role of ‘bullying’ in his work. The main characters in this work are “I” and “Ma.” “I” thought Ma was something like him. This is because “Ma” appeared to be frightened by his aggressiveness in “bullying”. Father-on-mother violence was the norm in “I”’s family. “I” both hated my father and feared that one day he would become like him. In this way, this work raises the possibility of being able to stand in solidarity with others through the medium of one’s own familiar “difficulty of living”. However, was that “I” was not aware that I was in a completely different position from Ma. As a result, “I” could not be conscious of his aggressiveness or imagine the structural violence “Ma” was subjected to. Through the above reading, we evaluate this work as a work that expresses through “bullying” the possibility and impossibility of standing in solidarity with others in a different position from our own.
A Study on ‘Villainess’ Japanese Web Novels Using Textmining Method
Authors: NAM Yoomin
Published: September 2023

To this point, research on web novels has centered on male-oriented works, with the result that the analysis of a small number of works has been applied to all such novels. With this in mind, this study examines the sub-genre of Japanese female-oriented web novels and the role of the ‘Villainess’ by employing text mining, a digital analysis technique. The Villainess is a character who opposes a female protagonist in an ‘Otome game’ or a ‘Shojo Manga’. A Villainess plot involves a narrative that makes the Villainess, who is originally a supporting character in the story, the main character. The villainous girl protagonist originally lives in modern Japan, enters the world of games or cartoons through the same process involved in her previous life, and is reborn as a high-status villain character. This new world is one that the main character has already experienced through game play or reading in the previous world. Originally, the villainous young lady is a character who torments the heroine, so she is inevitably given a tragic fate according to the logic of evil and punishment. The main character, who is reborn as a villain, changes her fate based on the world of the original game or manga she knows, in order to escape from this unfortunate fate. By transforming the narratives of games and cartoons in this way, the villainous heroine affirms women who live their lives faithfully and independently without attaching importance to dating, and foregrounds the narratives of such women. In this dimension of transformation, we can read the desire of modern Japanese female readers who are often seen as afficianadoes of villainous characters.
Senses of Language
Authors: KHEZRNEJAT Gregory
Published: September 2023

For most students beginning to study a second language, the image of the native speaker looms large. The native speaker is presented as a model of appropriate language use as well as the final arbiter of the validity of every utterance; to speak “like a native speaker” often becomes the explicit goal of study. But such monolithic images are more projections than reality. Even within communities of first-language speakers, there is an endless diversity of language use. if we accept that language is not a neutral tool to be mastered, but rather a dynamic medium shaped by and reflecting our personal experience of acquisition, then both the feasibility and desirability of speaking “like a native speaker” become questionable. In this essay, I consider what it means to be a first-language speaker and suggest that we may want to reevaluate our common hierarchies of language proficiency. As the use of second languages is becoming increasingly common, it is important to recognize the legitimacy of second-language speakers and their potential for enriching language communities. I discuss my how my own sense of appropriate language has evolved, and briefly touch on movement in the linguistics community to critically consider longstanding “native speaker” biases.

Published: September 2023

Background/Aim. Dental caries is a multifactorial disease that ultimately results in the demineralization of dental tissues and is recognized by the World Health Organization as the most prevalent disease among the global population. Dental varnishes are effective in preventing caries in children. The aim of this study was to investigate the way in which dental varnishes, one of which contained fluoride and the other casein phosphopeptideamorphous calcium phosphate (CPP-ACP), affect the microhardness and roughness of the three most commonly used restorative materials in pediatric dental practice [resin-modified (RM) glass ionomer cement (GIC), high-viscosity (HV) GIC, and micro-hybrid composite (MHCOMP)]. Methods. The study included 60 discs and 60 bars, of which 20 discs and 20 bars each were made from one of the three commonly used dental restorative materials. After preparation, incubation, and subsequent basic measurement, the samples were divided into two subgroups (each subgroup containing 30 discs and 30 bars), and each of them was treated with fluoride or CPP-ACP varnish according to a precisely established protocol. After treatment with varnishes, all samples were retested for microhardness and roughness. Results. The application of fluoride or CPP-ACP varnish in-creased the microhardness of the MHCOMP and RM GIC but reduced the microhardness of HVGIC. The roughness was more pronounced with the composite material, as well as with the RM GIC. Conclusion. Prophylactic varnishes containing fluoride and calcium have the potential to alter the microhardness and roughness of dental restorations; that is why carefully selecting the appropriate varnish is important.

С помощью маломощных источников УФ-излучения впервые изучено стациальное распределение совкообразных чешуекрылых в центральной части северного склона Киргизского хребта. Выявлено 174 вида, распределенных по 7 стациям: 78 в полынно-типчаковой степи, 111 в разнотравно-ковыльной степи, 94 на ксерофитном лугу, 49 на субальпийском лугу, 49 в зарослях кустарников, 40 в смешанном лесу, 13 в хвойном лесу. Показано, что фауны Noctuoidea большинства стаций на исследованной территории несходны, однако близкие по условиям стации (оба типа степей и ксерофитный луг, заросли кустарников и смешанный лес) объединяются в кластеры. Количество эврибионтных видов среди отмеченных для исследованного локалитета составляет 85%. Доля среднеазиатских эндемиков среди стенобионтных видов составляет более 57%.

For the first time, the habitat-related distribution of the owlet moths in the central part of the northern slope of the Kyrgyz Mountain Range was studied with the help of low-power UV-sources. In total, 174 species in seven types of habitats were identified: 78 species in the sagebrush-fescue steppe, 111 species, in the forb-feather grass steppe, 94, in the xerophytic meadow, 49, in the subalpine meadow and in the thickets of shrubs each, 40, in the mixed forest, and 13 species in the coniferous forest. The fauna of Noctuoidea at most stations in the study area are not similar, but the stations that are similar by conditions (both types of steppes and a xerophytic meadow, thickets of shrubs and mixed forest) are combined into clusters. The number of eurybiont species among those noted for the studied locality is 85%. The share of Central Asian endemics among stenobiont species exceeds 57%.
Targeting Spike Protein: Modified Antibody for Broad-Spectrum Binding to Coronaviruses: An In Silico Study
Authors: RC Rai
Published: September 2023

An antibody-mediated immune response against the Spike protein is one of the potential ways to target the SARS-CoV-2 virus. The discovery of a highly effective vaccine or an antiviral drug that specifically targets the viral entry or its replication pathway, are commonly pursued as a way to combat COVID-19-like situation. The SARS-CoV-2 virus has RNA as its genetic material, which is known for its high mutation rate. This makes the efficiency and efficacy of the vaccine against it suboptimal later due to the continuous mutations in the epitope region of the virus. This was evident in the case of the spread of the Omicron (B.1.1.529) variant. Here we tested an in-silico approach towards finding an antibody that has the potential to recognise and bind against the Spike protein of the virus across most of the variants. We achieved this by altering the sequences of the VDJ region in the heavy and light chains of the natural human antibody against the Spike protein of the SARS-CoV-2 virus (Wuhan, PDB ID: 7BWJ). This was one of the first antibodies to be studied and published along with a crystal structure during mid2020, and known to have the ability to bind and neutralize the Wuhan isolate. Iterative substitutions were induced in the 7BWJ antibody sequence in different combinations. After 28 iterations, a potential antibody was found to bind across the variants with a comparatively higher docking score. This antibody also showed the potential to target the Spike protein of many members of Coronaviruses.

Published: September 2023

Background: The STEAM (Science, Technology, Engineering, Arts, and Mathematics) approach in education has been gaining traction for its holistic and integrated framework that fosters critical and reflective thinking. Previous studies have shown its effectiveness in various aspects of mathematical competencies, yet there is limited research concerning its impact on students' reflective thinking skills in statistical material.Aim: This study aims to analyze students' mathematical reflective thinking skills in statistical material, using the STEAM approach.Method: Utilizing a qualitative research design, this study engaged six twelfth-grade students from MAN 1 Karanganyar as its subjects. Data were gathered through a combination of essay-based tests focused on data interpretation tasks and comprehensive interviews. The analysis was performed through observation, interviews, testing, and data triangulation, followed by thematic data reduction.Result: The findings disclose that students exhibited varying degrees of mastery over reflective thinking in the context of tackling statistical problems. While they demonstrated competence in technical and mathematical aspects under the STEAM approach, their proficiencies were less apparent in scientific, artistic, and technological dimensions.Conclusion: The study concludes that although the STEAM approach facilitates technical and mathematical skill enhancement, it may not fully equip students with comprehensive reflective thinking skills, particularly in statistical contexts. Therefore, there is a need for a more targeted pedagogical approach to bridge these gaps and cultivate well-rounded, reflective thinkers.

Published: September 2023

Science learning in elementary schools is expected to provide students with an understanding of scientific terms through experiments that can provide generic science skills. But this is still rarely done at the elementary school level. This study aims to analyze the science generic skills of elementary school students as an effort by the teacher to create learning that is able to make students understand and remember scientific terms. This study is qualitative approach. Sources of data in this study were obtained from class teachers and fifth grade students at Elementary School Muhammadiyah 22 Surakarta. Data collection techniques using observation, interviews and documentation. Test the validity of the data using the credibility test and source triangulation. Data analysis techniques consist of data collection, data presentation, drawing conclusions, and verification. The results showed that students' generic science skills in science learning obtained a percentage of 75%. The highest score is in the aspect of symbolic language (25%) shown by the activities of students mentioning symbols, symbols and scientific terms in presentations related to the water cycle process. The lowest score 0% absence of student activities. The research contribution is teachers must teach science through experimental activities of measuring rainfall, or similar experiments that are adapted to the topic of the material so that aspects of generic science skills can be developed in a more balanced way in each aspect so as to be able to provide more comprehensive science skills and knowledge in learners.
Possibilities of using mussels (Mytilus galloprovincialis) to predict rotavirus contamination in Albania
Authors: Lugaj Arta , Korro Kastriot , Tolomeo Anna Maria , Bakiu Rigers , Santovito Gianfranco
Published: September 2023

Introduction

Rotaviruses are non-enveloped viruses that each consist of 11 double-stranded RNA molecules. These viruses are able to persist in the environment, and therefore play a fundamental role in the epidemiology of gastroenteritis and severe diarrhoea in children worldwide. While mussels have been primarily used as indicators of chemical pollution, they can also be used to monitor viral contamination. The purpose of this study was to demonstrate that the Mytilus galloprovincialis mussel can also be used to detect microbial contamination, owing to its tendency to naturally concentrate viruses and other pathogens.

Material and Methods

A total of 102 Mytilus galloprovincialis mussel samples from Albania were collected over a three-year period: 37 samples off the Cape of Stillo in 2015, 39 samples from Butrinti Lake in 2019 and 26 samples from Butrinti Lake in 2021.

Results

The presence of rotavirus in the Cape of Stillo samples in 2015 was noted in 47% of samples from site 1, 33% from site 2, and 52% from site 3. In Butrinti Lake the percentage of infected individuals in 2019 was 33% from site 1, 41% from site 2, and 33% from site 3, whereas in 2021, it was 50% from site 1, 19% from site 2, and 0% from site 3. In total the percentage of infected individuals off the Cape of Stillo in 2015 was 44%, in Butrinti Lake in 2019 it was 36%, and in Butrinti Lake in 2021 it was 23 %.

Conclusion

These results indicate the presence of rotavirus in the shellfish specimens tested, and further analysis is needed to assess the potential health risks associated with consuming these shellfish. This study also indicates that mussels can be used in marine virological surveillance programmes.

Establishing an appropriate organizational structure is an essential condition for the successful implementation of a corporate strategy. According to current strategists, strategy and structure are interrelated and should be developed in parallel. There is no definitive organizational structure of a company. Based on theories and research on the organizational structure of selected passenger rail transport organizations, it has been shown that an appropriate organizational structure is an important prerequisite for the implementation of the selected strategy. New organizational structures can provide new and interesting opportunities for managers and employees. However, these structures may pose a threat to employees due to the scale of work and, possibly, they may threaten their job. Developing new organizational structures without considering the consequences for those affected is surely inappropriate. At a time of liberalization and increasing competition, an effective organizational strategy is becoming a significant competitive advantage for rail passenger transport organizations.

In this work, we build a satellite attitude Proportional-Integral-Derivative (PID) controlled system by using the Hubble Space Telescope (HST) parameters as a reference and tune its controller parameters using various tuning methods. First, we give the equations for the motion of a satellite. We elaborate the control structure as controller, actuator, dynamics, and kinematics subsystems and construct an external disturbance model. We use a reaction wheel assembly used in the HST with the same configuration as the actuator. We evaluate the performance of the linearization by comparing it with the nonlinear model output. By working on the linearized model, we tune the PID controller parameters using two different methods: “Model-Based Root Locus Tuning” and “Genetic Algorithm Based Tuning”. First, we obtain the controller parameters by manipulating the poles on the root locus plot of the linearized system. In addition, we use genetic algorithms to find the optimized controller values of the system. Finally, we compare the performances of the two methods based on their cost function values and find that the Genetic Algorithm-based tuned parameters are more fruitful in terms of the cost function value than the parameters obtained by the Root Locus-based tuning. However, it is found that the Root Locus-based tuning performs better in disturbance rejection.

Wood charcoal is a sustainable, renewable, and environmentally friendly material with the use that the acoustic device can produce. Charcoal made of wood waste materials allows for improving indoor acoustical quality. Therefore, this objective of the article is to investigate the sound scattering coefficients of QRD with the perforation ratio of oak wood charcoal elements. Sound scattering coefficient calculated with the measurement of the reverberation time in the reverberation chamber. The calculation results of the scattering coefficient show the growth of scattering in the frequencies - the highest value reached 0.88 (diffuser N7 with charcoal). The effectiveness of diffusers to diffuse sound waves increases as the number of wells grows. The diffuser with 80 % charcoal elements showed a higher scattering coefficient compared to the diffuser without charcoal elements.

Klinik sanitasi atau yang disebut dengan Breaksit Reborn (Brantas penyakit bersama klinik sanitasi) didirikan tahun 2017 di Puskesmas Kecaatan Kebon Jeruk. Namun kejadian ISPA dan tuberkulosis masih tergolong tinggi dari tahun ke tahun. Penelitian dilaksanakan pada bulan April 2022 menggunakan pendekatan kualitatif dengan teknik pengambilan data wawancara mendalam, observasi, dan telaah dokumen. Informan dalam penelitian ini terdiri dari 5 orang yaitu Kepala Puskesmas,  2 petugas sanitarian, dokter ISPA dan dokter TB. Hasil Penelitian: Pelayanan klinik sanitasi pada penyakit ISPA tidak berjalan di masa pandemi. Kunjungan pasien Tuberkulosis yang melakukan konseling di pelayanan klinik sanitasi lebih banyak dibandingkan pasien ISPA. Gejala yang dikeluhkan pada penyakit ISPA demam, batuk, flu dan sesak nafas, sedangkan gejala pasien TB batuk menahun, berat badan turun, keringat malam, batuk darah, menggigil, dan nafsu makan berkurang. Pelayanan klinik sanitasi sudah tersedia sejak tahun 2017 dan fasilitas klinik sanitasi di Puskesmas Kecamatan Kebon Jeruk sudah memadai. Kesimpulan: Pelayanan klinik sanitasi perlu ditingkatkan mengingat gejala penyakit berbasis lingkungan memiliki kemiripan, baik ISPA, TB, maupun Covid-19. Puskesmas diharapkan untuk lebih mengoptimalkan pelayanan klinik sanitasi, dan melakukan kerja sama dengan dokter ISPA dan TB baik dalam pelayanan dalam maupun luar ruangan.---A sanitation clinic or what is known as Breaksit Reborn (disease fighting together with a sanitation clinic) was established in 2017 at the Kebon Jeruk District Health Center. However, the incidence of ARI and tuberculosis is still relatively high from year to year. The research was conducted in April 2022 using a qualitative approach with in-depth interview data collection techniques, observation, and document review. The informants in this study consisted of 5 people, namely the Head of the Puskesmas, 2 sanitarian officers, an ARI doctor and a TB doctor. Research Results: Sanitation clinic services for ARI disease do not run during the pandemic. Tuberculosis patients who do counseling in sanitation clinic services are more than ARI patients. Symptoms complained of in ARI are fever, cough, flu and shortness of breath, while the symptoms of TB patients are chronic cough, weight loss, night sweats, coughing up blood, chills, and decreased appetite. Sanitation clinic services have been available since 2017 and sanitation clinic facilities at the Kebon Jeruk District Health Center are adequate. Conclusion: Sanitation clinic services need to be improved considering the symptoms of environmental-based diseases have similarities, both ARI, TB, and Covid-19. Puskesmas are expected to further optimize sanitation clinic services, and cooperate with ARI and TB doctors both in indoor and outdoor services.

Natrium siklamat (C6H12NNaO3S) merupakan salah satu jenis pemanis buatan yang memiliki tingkat kemanisannya kurang lebih 30 kali dari pada sukrosa dengan jumlah kemanisan yaitu 3,94 kkal/g. Anak-anak paling rentan terhadap dampak negatif pemanis buatan, untuk anak-anak berpotensi merangsang keterbelakangan mental karena otak masih dalam tahap perkembangan dan terakumulasi pada jaringan syaraf. Penelitian ini bertujuan untuk mengetahui kandungan siklamat pada minuman es teh yang dijual oleh pedagang keliling di empat Sekolah Dasar Kelurahan Melayu, Kecamatan Tenggarong. Penelitian ini merupakan jenis penelitian deskriptif dengan pemeriksaan laboratorium menggunakan uji kualitatif dengan metode pengendapan padalima penjual minuman es teh keliling di Sekolah Dasar Kelurahan Melayu. Hasil penelitian menunjukkan bahwa dari total lima sampel uji terdapat 2 sampel es teh positif mengandung siklamat. Berdasarkan data dapat disimpulkan bahwa kedua sampel es teh yang positif mengandung siklamat diketahui karena penggunaan serbuk minuman instan yang mengandung Natrium Siklamat pada saat observasi dilakukan.---Sodium cyclamate (C6H12NNaO3S) is one type of artificial sweetener which has a sweetness level of approximately 30 times that of sucrose with a total sweetness of 3.94 kcal/g. Children are most vulnerable to the negative effects of artificial sweeteners, for children it has the potential to stimulate mental retardation because the brain is still in a developmental stage and accumulates in neural networks. This study aims to determine the content of cyclamate in iced tea drinks sold by traveling vendors in four elementary schools in the Melayu Village, Tenggarong District. This research is a descriptive type of research with laboratory examination using a qualitative test with precipitation method on five mobile iced tea drink sellers in the Elementary School of Melayu Village. The results showed that from a total of five test samples, there were 2 samples of iced tea that were positive for cyclamate. Based on the data, it can be concluded that the two samples of iced tea that were positive for containing cyclamate were known to be due to the use of instant drink powder containing sodium cyclamate at the time of observation.
