Authors: Rahayu Tutiek , Fauzan Aji Nur Nur , Pertiwi Kartika Ratna
Published: March 2024

The purpose of this study was to determine the sanitation hygiene of the school canteen, the contribution of wet snack food to meeting the daily nutritional needs of students and to find out whether there were differences in sanitation and nutritional hygiene between wet snacks sold in the school canteen between Adiwiyata school canteens and non-Adiwiyata schools. This type of research is a descriptive observational research. The sample in this study is packaged and unpackaged snacks which are often sold in the school canteen. The variables in the study were the condition of the snacks in SD Adiwiyata and SD non-Adiwiyata in Bantul Regency. The standard instrument from the Indonesian Ministry of Health regarding hygiene, sanitation and nutritional content of food uses a computer application "nutry survey" and the E. coli test at the Microbiology Laboratory of the Faculty of Mathematics and Natural Sciences UNY. The result of the research is that the value of hygiene and sanitation of SD Adiwiyata canteen is 81.43% with good criteria, while non-Adiwiyata elementary school is 68.81% with moderate criteria. The average energy adequacy per day is 1461.6 kcal, while the recommended energy adequacy is 1594.5 kcal, thus only 92% fulfilled. There are differences in the hygiene and sanitation of wet snack food canteens between Adiwiyata and non-Adiwiyata elementary schools. Judging from the presence of E.coli and mold contamination, snacks in non-Adiwiyata school canteens showed that the number of E.coli and molds was higher than Adiwiyata Elementary School both in the morning and in the afternoon. Keywords : hygiene, sanitation, food nutrition, canteen
Misconception tendency of differentiated instruction in publicly shared teaching and learning videos on youtube: A mixed-methods exploration study
Authors: Putra Guruh Sukarno
Published: March 2024

Differentiated instruction is a pedagogical approach in which teachers fulfill students' needs based on their interests and learning profiles. This paradigm is new to the Indonesian educational sector as the government of Indonesia introduced the Merdeka curriculum in 2022, which offers a new style of teaching and learning in Indonesia through differentiation in the classroom. As an unfamiliar approach, the recent practice of differentiated instruction may lead to a misconception, particularly in its implementation. This paper focuses on witnessing teachers' misconceptions regarding differentiated instruction in three major aspects: teacher-student relations, teacher-learning design, and teacher-learning goals, using a mixed method with an explanatory sequential design. The first phase includes video observation for qualitative data collection to build variables and obtain quantitative results. This research used a purposive sampling technique with a total of seventy-seven teaching and learning in Indonesian high school videos from YouTube with particular keywords related to differentiation. All the videos were uploaded on YouTube in 2022, ranging from January 2022 to December 2022, and were from various origins and subjects. The final result and interpretation show that the score of differentiated instruction implementation through the observation checklist was 0.4722, considered satisfactory. Furthermore, this study identifies three aspects of differentiation that need to be strengthened, including learning pace settings, giving oral feedback to students based on their needs, and responding proactively to diverse students. The recommendations for tackling misconceptions regarding differentiated instruction are given for better future implementation.

Published: March 2024

Purpose: The 2018 healthcare waste management crisis catalyzed a critical review of the concerns expressed by the Health Office (dinkes) and healthcare facilities regarding healthcare waste management in the Special Region of Yogyakarta (DIY). Due to this crisis, the Ministry of Health hired Universitas Gadjah Mada (UGM) to look into potential solutions and promote DIY government policy responses. This paper examines the management strategy during crisis times and possible alternative solutions.

Methods: This paper uses focused group discussions reports involving separate groups of (1) environmental health officials from community health centers, (2) hospitals, (3) environment health officials of district health authorities, and (4) cross-sectoral province officials in the Yogyakarta Special Region. It is part of a project 'A case study of strengthening regional-based medical waste management model', fund from the Environmental Health Directorate, Directorate General of Public Health, Ministry of Health (Project KN 01.03/6.1/0198/2019).

Result: A simulation of policy options based on health facility managers suggests that a province-based system is the most profitable in the long term for DIY, with several possible options. The national policy roadmap was considered inadequate to respond to DIY's urgent local needs. Furthermore, the series of meetings succeeded in forming an informal forum between health facilities, provincial health offices, and associations of hospital environmental sanitation experts, monitoring medical waste management.

Conclusion: The 2018 medical waste management crisis led to the formulation of policy response choices tailored to the capacity of DIY. These choices considered the expenditures and legal sanctions faced by healthcare facilities and the economic value of a region-based waste system for local government authorities. This comprehensive approach highlights the importance of local capacity. It needs to shape effective and sustainable medical waste management policies, underscoring the necessity of region-specific strategies in the face of national health crises.
Elderly care by village health volunteers during COVID-19 pandemic in Thailand
Authors: Sumiar Haening Ratna , Viwatpanich Kanvee
Published: March 2024

Purpose: This study aimed to understand how village health volunteers (VHV) perform their duties and look after older adults during the COVID-19 pandemic health crisis.

Methods: We used in-depth interviews, group interviews, and observation to collect the data. This study was carried out in Wat Rong Lot, Chiang Rai, Thailand. Eleven people were involved in this research including one Public Health Department officer, Master of the Temple, five VHVs, one nurse, and three older adults in the community. We used content analysis to analyze our data.

Results: Before the pandemic, VHV’s duties included health screening and monitoring, reporting the results to the primary health center, and health education to the older adults in the community. During the pandemic, they perform these duties by making a monthly visit to conduct ADL and living arrangement assessment and drug delivery. Since the lockdown, many VHV duties must be shifted which resulted in pausing regular care plans for the elderly. However, VHVs keep delivering health services to the elderly by making home visits in case of an emergency, drug delivery, and donating masks and medical supplies. They were burdened with additional responsibilities related to COVID-19 prevention, detection, and surveillance. They admitted to facing some challenges such as being unconfident when performing their work and distrust from the community.

Conclusion: The additional responsibilities and lockdown hinder regular treatment. Further research is needed regarding the impact of care plan cessation for the elderly.

Desafíos del debido proceso penal en la diversidad cultural
Authors: Ocampo Muñoa Manuel Gustavo
Published: March 2024

Este documento es una reflexión acerca de los desafíos que el debido proceso penal enfrenta en el contexto de los pueblos y comunidades originarias; escenarios en los que la diversidad cultural se convierte en un obstáculo para el acceso a la justicia. Es mediante el enfoque intercultural del derecho que pueden encontrarse alternativas de solución a los conflictos que se generan dentro de esa complejidad. Se pretende demostrar que en los pueblos originarios la construcción del derecho al debido proceso penal debe incluir componentes interculturales tales como el diálogo, el respeto a las diferencias, los saberes diversos, la cosmovisión, el dominio de la lengua materna, para garantizar a la ciudadanía el máximo disfrute de sus derechos y libertades. El contexto de los pueblos originarios de Chiapas se utiliza para argumentar lo anterior, dado que en dicha entidad habitan al menos doce de los reconocidos por la ley y las instituciones gubernamentales.

Automatic Transmission Line Fault Detection System Using GSM Technology
Authors: Kadao Pankaj D.
Published: March 2024

Abstract: The electrical system is divided into several different parts. One of them is the transmission system, where electricity is transmitted from substations and substations along power lines to consumers. Both methods can experience various types of errors, often referred to as "problems". A fault is simply defined as a sequence of unwanted but unavoidable events that can temporarily disturb the steady state of a power system when the insulation of the system fails at some point. An intelligent fault finding and localization system was used to adequately and accurately mark and locate the occurrence of a fault. This ensures a shorter response time for the technical team to fix these faults, thus helping to save transformers from damage and disasters. The system uses current transformer, voltage transformer, Arduino uno controller, RS-232 connector and LCD display, GSM module, audio signal. The system automatically detects faults, analyzes and classifies them, and then calculates the distance of the fault from the control room by means of an algorithm based on impedance. Finally, the error information is transmitted to the control room.

Classical shadows based on locally-entangled measurements
Authors: Ippoliti Matteo
Published: March 2024

We study classical shadows protocols based on randomized measurements in n-qubit entangled bases, generalizing the random Pauli measurement protocol (n=1). We show that entangled measurements (n≥2) enable nontrivial and potentially advantageous trade-offs in the sample complexity of learning Pauli expectation values. This is sharply illustrated by shadows based on two-qubit Bell measurements: the scaling of sample complexity with Pauli weight k improves quadratically (from ∼3k down to ∼3k/2) for many operators, while others become impossible to learn. Tuning the amount of entanglement in the measurement bases defines a family of protocols that interpolate between Pauli and Bell shadows, retaining some of the benefits of both. For large n, we show that randomized measurements in n-qubit GHZ bases further improve the best scaling to ∼(3/2)k, albeit on an increasingly restricted set of operators. Despite their simplicity and lower hardware requirements, these protocols can match or outperform recently-introduced "shallow shadows" in some practically-relevant Pauli estimation tasks.

Published: March 2024

Â Â Â Â Â Â Â  Indonesian students' ability in mathematical literacy is classified as low; this is shown in several PISA survey results. What causes students' low mathematical literacy abilities in Indonesia is the need for more application of learning models and media that support students' mathematical literacy abilities. This research analyzes students' mathematical literacy skills using problem-based learning-based mathematical comics. This research is a type of qualitative research. The subjects of this research involved 25 class VIIIâ€”1 students at one of the schools in Batanghari, namely SMPN 21 Batanghari. The data collection technique in the study was a mathematical literacy ability test consisting of 5 essay questions. Data analysis in this research includes data reduction, data presentation, and concluding/verification. The research results showed that of the 25 students who took the mathematical literacy ability test, as many as 11 students, or 44%, had high levels of mathematical literacy skills. As many as 14 students, or 56% of students, had moderate mathematical literacy skills. No students had average levels of mathematical literacy skills. Low-level mathematics. Thus, it is concluded that students' mathematical literacy abilities after learning using problem-based learning-based mathematical comics fall into the category of medium-level mathematical literacy abilities as seen from the average score obtained on the students' mathematical literacy ability test, which is 79,72.
Profile of Student Metacognition in Solving Elementary Linear Algebra Problems Viewed from Tempo Conceptual Cognitive Style
Authors: Kartika Dwiani Listya , Muhassanah Nuraini
Published: March 2024

Metacognition is one of the factors that influences students' success in solving mathematical problems. On the other hand, the reality in the field is that students experience difficulties in solving mathematical problems related to Elementary Linear Algebra because they contain a lot of repetitive calculations, so they require high levels of perseverance and accuracy. This research aims to describe students' metacognitive profiles in solving Elementary Linear Algebra problems in terms of cognitive style. The cognitive style chosen is the conceptual cognitive style of pacing through Matching Familiar Figures Tests with research subjects being mathematics students at Nahdlatul Ulama University, Purwokerto. The resulting metacognition profile was obtained from Elementary Linear Algebra problem-solving test data and interviews, which were analyzed and concluded through a series of method triangulation processes. The research results show that students are reflective and impulsive in carrying out all activities that are indicators of metacognitive awareness and regulation, as well as several indicators from metacognitive evaluation. Fast, accurate students carry out all activities that become indicators of metacognitive awareness, regulation, and evaluation. Meanwhile, slowly, inaccurate students carry out all activities that are indicators of metacognitive awareness and several indicators of metacognitive regulation but still need to be able to carry out activities of metacognitive evaluation.

Published: March 2024

Respiratory syncytial virus (RSV) is one of the leading causes of severe
respiratory diseases in children, especially in infants. RSV infections
result in an estimated $80 billion each year in economic losses
globally. The immune responses induced by RSV infection are a fairly
complex process that can contribute significantly to disease severity.
Despite decades of research on RSV, many immune mechanisms remain to be
explored. Despite substantial progress in vaccine development and the
development of monoclonal antibodies over the years, there are still not
enough effective preventive and therapeutic strategies. Recently, Pfizer
developed a pre-fusion F subunit vaccine for preventing RSV infection in
infants, the only vaccine currently approved by the FDA. This review
focuses on how the immune system reacts when children contract the
respiratory syncytial virus. We described the biological characteristics
of RSV, the pathological process of RSV infection, innate
immunity（including Pattern Recognition Receptors and inflammatory
cells）, adaptive immunity (including CD4+ and CD8+ T cells and Humoral
Immune Response), and immune evasion. Understanding the complicated
immune response to RSV infection is essential for developing effective
interventions and vaccine developments. This review will enable an
appreciation of how RSV affects the immune system and enhance the
advancement of pragmatic therapeutic methodologies.

Published: March 2024

Integrated multimodal imaging in theranostics nanomaterials offers
extensive prospects for precise and noninvasive cancer treatment.
Precisely controlling the structural evolution of plasmonic
nanoparticles is crucial in the development of photothermal agents.
However, previous successes have been limited to static assemblies and
single-component structures. Here, an activatable plasmonic theranostics
system utilizing self-assembled 1D silver-coated gold nanochains (1D
nanochains) is presented for precise tumor diagnosis and effective
treatment. The absorbance of the adaptable core-shell chain structure
can shift from visible to near-infrared (NIR) regions due to the fusion
between nearby Au@Ag nanoparticles induced by elevated H
O levels in the tumor
microenvironment (TME), resulting in the creation of a novel 3D
aggregates with strong NIR absorption. With a high photothermal
conversion efficiency of 60.2% at 808 nm, nanochains utilizing the
TME-activated characteristics show remarkable qualities for
photoacoustic imaging and significantly limit tumor growth in vivo. This
study may pave the way for precise tumor diagnosis and treatment through
customizable, optically tunable adaptive plasmonic nanostructures.
The Generic Mapping Tools and Animations for the Masses
Authors: Wessel Paul , Esteban Federico Damián , Delaviel-Anger Guillaume
Published: March 2024

The Generic Mapping Tools (GMT) is a well-known set of software
originally developed for geosciences, allowing scientists in climate and
solid earth disciplines to routinely create publish-ready maps and
graphics. However, GMT users rarely make animations despite their
undeniable benefit for understanding and teaching dynamical processes.
As reading habits shift from print to digital, capitalizing on
animations for illustrating scientific concepts is more accessible than
ever. In the latest GMT version (6.5) we have added and refined the
moving-making modules, alleviating the time-consuming steps that would
hinder GMT users from making such animations. In this paper we will
explain how GMT ”movie” works then provide six representative
examples, from basic to more advanced, to show some of its key features.
We hope our presentation will encourage the masses to routinely create
animations for their publications.
High-resolution Neural Network Demonstrates Strong CO2 Source-Sink Juxtaposition in the Coastal Zone

Published: March 2024

Coastal oceans may play an important role in regulating the
concentration of carbon dioxide in the atmosphere. Quantification of
carbon fluxes at this highly dynamic land-ocean interface will aid in
monitoring, reporting, and verification for marine carbon dioxide
removal. Here, we use a two-step neural network approach to generate
basin-wide estimates from sparse observational data in the coastal
Northeast Pacific Ocean at an unprecedented spatial resolution of 1/12°
with coverage in the nearshore (0 - 25 km offshore). We compiled partial
pressure of carbon dioxide (pCO2) observations as well as a range of
predictor variables including satellite-based and physical oceanographic
reanalysis products. With the predictor variables representing processes
affecting pCO2, we created non-linear relationships to interpolate
observations from 1998-2019. Compared to in situ shipboard and mooring
observations, our coastal pCO2 product captures broad spatial patterns
and seasonal cycle variability well. A sensitivity analysis identifies
that the parameters responsible for the neural network’s ability to
capture regional pCO2 variability agrees with mechanistic processes.
Using wind speed and atmospheric CO2, we calculated air-sea CO2 fluxes.
We report an anticorrelation between net annual air-sea CO2 flux and
air-sea CO2 flux seasonal amplitude and suggest the relationship is
driven by regional processes. We show the inclusion of nearshore net
outgassing fluxes lowers the overall regional net flux. Overall, our
results suggest that the region is a net sink (-0.7 mol m-2 yr-1) for
atmospheric CO2 with trends indicating increasing oceanic uptake due to
strong connectivity to subsurface waters.

Published: March 2024

Acute and chronic SGLT-2 inhibition increase endogenous glucose production (EGP). However, the organ - liver versus kidney - responsible for the increase in EGP has not been identified. 20 T2DM and 12 NGT subjects received [3-3H]-glucose infusion (to measure total EGP) in combination with arterial and renal vein catheterization and PAH infusion for determination of renal blood flow. Total EGP, net renal arteriovenous balance, and renal glucose production were measured before and 4 hours after dapagliflozin and placebo administration. Following DAPA, EGP increased in both T2D and NGT from baseline to 240 minutes, while there was a significant time-related decrease after placebo in T2D. Renal glucose production at baseline was <5% of basal EGP in both groups and did not change significantly following DAPA in either NGT and T2D. Renal glucose uptake (sum of tissue glucose uptake plus glucosuria) increased in both T2D and NGT following DAPA (P<0.05 vs placebo). The increase in RGU was entirely explained by the increase in glucosuria. Single dose of dapagliflozin significantly increased EGP, which primarily is explained by an increase in hepatic glucose production, establishing the existence of a novel renal-hepatic axis.

Published: March 2024

Community service activities can reduce disaster risk in Srengsem Village, Indonesia, which is prone to floods and landslides during the rainy season. A survey and analysis of the disaster conditions in Srengsem was conducted to develop structural and non-structural mitigation recommendations, which were then conveyed to affected residents and local regional leaders. Structural mitigation recommendations included, for example, reinforcing buildings and installing drainage systems. Non-structural mitigation focused on increasing community preparedness for disasters through activities such as landslide/flood surveys, outreach, coordination, presentations at community meetings, and distribution of posters and pocket books. These activities helped residents and sub-district officials who previously did not have an understanding of disasters and preparedness to become more knowledgeable and able to carry out mitigation actions independently at the community level.

Beton adalah bahan bangunan yang mendukung upaya pembangunan dan ramah lingkungan apabila mampu memanfaatkan bahan yang merupakan limbah dari industri seperti limbah kulit kopi. Limbah kulit kopi merupakan hasil penggilingan buah kopi yang belum dimanfaatkan secara optimal. Limbah kulit kopi dapat dimanfaatkan dalam konstruksi yaitu sebagai bahan tambahan pada campuran beton yang di harapkan dapat menghasilkan beton padat dan keras dengan cara limbah kulit kopi di bakar kemudian di haluskan. Tujuan penelitian untuk mengetahui pengaruh kuat tekan, kuat tarik belah dan kuat lentur campuran kulit kopi 5%, 10% dan 15% dari berat semen pada beton umur 28 hari fc’ 20 MPa. Metode penelitian yang digunakan adalah eksperimental dalam data kuantitatif dengan sifat data kontinum. Hasil pengujian menunjukan bahwa berat jenis beton masuk kategori beton normal dalam rentang 2200-2500 kg/m³ dan nilai slump masuk dalam rentang rencana 60-180 mm. Hasil Pengujian kuat tekan, kuat tarik belah dan kuat lentur tambahan kulit kopi tidak dapat meningkatkan kekuatan beton dan terjadi penurunan kekuatan dari beton normal. Penurunan kekuatan terjadi karena kulit kopi yang halus dan ringan tidak dapat di ikat oleh semen ketika bereaksi dengan air, sehingga tidak dapat mengisi rongga pada beton dan kekurangan daya lekatnya.

Pertumbuhan jumlah penduduk yang makin lama makin meningkat mengakibatkan penggunaan moda transportasi udara juga semakin meningkat. Penggunaan transportasi udara lebih disukai karena dapat menjangkau daerah yang cukup jauh dengan waktu tempuh yang lebih singkat. Pada sektor ekonomi juga diuntungkan dengan adanya transportasi udara, semua orang dapat membeli barang dari manapun mereka berada tanpa harus ketempat tersebut. Untuk meningkatkan pelayanan pada sektor penerbangan salah satu hal yang dilakukan yaitu menambah jumlah pesawat dengan kapasitas besar. Dengan bertambahnya jumlah pesawat mengakibatkan beban yang melalui runway bandara semakin besar. Untuk mengetahui apakah runway cukup kuat dalam menahan beban pesawat, evaluasi terhadap tebal perkerasan runway harus dilakukan. Pada penelitian ini evaluasi dilakukan dengan menggunakan software COMFAA. Data yang digunakan pada penelitian ini yaitu data pesawat yang melalui bandara Fatmawati, data CBR lapangan dan data eksisting perkerasan runway bandara Fatmawati. Data tebal perkerasan eksisting pada runway bandara untuk STA 0+100 sampai 1+800 yaitu 105 cm dan STA 1+800 sampai 2+250 yaitu 107,5cm, dengan nilai CBR lapangan 6% dan jenis pesawat B737-900ER serta A320 Twin opt.  Hasil analisis menggunakan COMFAA menunjukkan nilai PCN > ACN dan nilai CDF < 1. Sehingga perkerasan runway bandara Fatmawati Soekarno masih layak dan aman digunakan untuk jenis pesawat Boeing 737-900 ER dan A320 Twin opt.
