Authors: Fikry Muhammad , Bustami  , Suzanna Ella 
Published: February 2025

Objective: This study investigates the impact of classroom environmental conditions on student mental health through an integrated Internet of Things (IoT) system. The primary objective is to assess how temperature, humidity, and noise levels influence student well-being and engagement.

Theoretical Framework: The study is grounded in environmental psychology and cognitive load theory, emphasizing how physical learning environments affect cognitive function and emotional well-being.

Method: Data were collected from classrooms in four schools using IoT-based sensors to monitor temperature, humidity, and noise. The mental health of 267 students was assessed using the Hopkins Symptom Checklist. Statistical analyses examined correlations between environmental conditions and psychological well-being.

Results and Discussion: Findings indicate that 42.79% of students exhibited anxiety symptoms and 42.36% showed depression signs, yet only 28.46% sought counselling. Classroom conditions were suboptimal, with an average temperature of 29.8°C and humidity of 80.5%. Noise disturbances affected 61.05% of students, and 50.55% reported temperature discomfort. Statistical analyses revealed a negative correlation between temperature and student activity levels and a positive correlation between humidity and focus.

Research Implications: This study highlights the need for real-time environmental monitoring in schools to enable timely interventions and improve student well-being.

Originality/Value: This research uniquely integrates IoT-based environmental monitoring with direct mental health identification through real-time data analysis. The proposed IoT framework consists of sensor networks that capture environmental parameters and correlate them with student responses using machine learning models. This novel approach enables proactive interventions, providing a structured strategy for improving mental health in educational settings.

Objective: The aim of this research is to analyze the relationship between the increase in the incidence of periodontal disease and the levels of nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO) in the air of Banjarbaru City.

Theoretical Framework: The relocation of the capital from Banjarmasin to Banjarbaru, South Kalimantan can have negative impacts. One of them is the occurrence of air pollution. Air pollution is suspected to be related to the incidence of periodontal disease due to the presence of several pollutants, including NO2, SO2, and CO. However, further studies are needed to examine the relationship between these pollutants and the incidence of periodontal disease.

Method: Data on pollutants NO2, SO2, and CO for the years 2021 and 2024 were obtained through spatial analysis using the Google Earth Engine (GEE) application. The data obtained will subsequently be visualized with the help of SURFER Version 23 software. The incidence data of periodontal disease in 2024 was obtained from the Banjarbaru City Health Office. The increase in pollutant levels was analyzed using a paired T-test, and the relationship between pollutants and periodontal disease was analyzed using multiple linear regression.

Results and Discussion: The research results showed a significant increase in SO2 and CO levels (P < 0.05). The research results also showed an increase in the incidence of periodontal disease from January to December 2024. An increase of 84.86% in periodontal disease is significantly related to air pollutant levels. The results of the statistical test showed a relationship of R2 = 0.72 (p=0.01; p<0.05). The pollutant that is significantly related to this disease is CO (p=0.00; p<0.05).

Research Implications: The results of this study prove that the increase in the incidence of periodontal disease in the city of Banjarbaru is related to the increase in air pollutant levels, particularly CO. The results of this study are expected to serve as a guideline for improving air quality in the city of Banjarbaru.

Originality/Value: The results of this study provide a new perspective on the impact of air pollution on dental health. Some previous research results have extensively discussed the relationship between dental and oral diseases and the increase in PM2.5 and PM10, but this research provides a new perspective that CO pollutants can also increase the risk of dental and oral diseases, particularly periodontal diseases.

Pemanfaatan Kefir dalam Mencegah Kerusakan Hepar Akibat Toksisitas Parasetamol
Authors: Susanti Erna , Rahayu Windaniyah Sri 
Published: February 2025

Parasetamol obat yang umum digunakan untuk penghilang nyeri dan demam harus diwaspadai terkait efek samping yang ditimbulkan. Meskipun parasetamol merupakan obat yang aman tetapi jika tidak digunakan secara tepat efek samping hepatotoksik dapat terjadi. Sumber radikal bebas dapat berasal dari endogen (mitokondria, retikulum endoplasma, sel fagositosis) maupun eksogen (polusi, alkohol, merokok, logam berat, pestisida, obat seperti halotan, parasetamol dan radiasi). Obat bisa berperan sebagai sumber radikal bebas jika fungsi hepar sebagai organ pemetabolisme tidak berperan sebagaimana mestinya. Tujuan penelitian ini adalah untuk membuktikan efek kefir dalam mencegah kerusakan hepar akibat toksisitas parasetamol. Malondialdehid (MDA) digunakan sebagai marker terjadinya stress oksidatif dan kerusakan hepar sebagai organ pemetabolisme yang dapat ditentukan kadarnya dengan metode Thiobarbituric Acid Reactive Substance (TBARS). Hasil penelitian menunjukkan bahwa kefir pada dosis 1,15 x 108 CFU/ml sebanyak 1 ml mampu menurunkan kadar MDA hepar. Kefir mengandung vitamin C dan E serta mineral yang berperan sebagai antioksidan sehingga dapat menghambat ataupun menetralkan terbentuknya radikal bebas. Sehingga dapat disimpulkan bahwa kefir mampu memperbaiki kerusakan hepar karena efek hepatotoksik parasetamol pada dosis tersebut.

Hepatoprotektor merupakan suatu senyawa yang memiliki kemampuan untuk melindungi hati dari kerusakan akibat senyawa-senyawa hepatotoksik. Kerusakan hati dapat diamati melalui peningkatan kadar enzim serum glutamic oxaloacetic transaminase (SGOT) dan serum glutamic pyruvic transaminase (SGPT). Enzim tersebut akan meningkat jumlahnya dalam darah saat organ hati mengalami stres oktsidatif. Beberapa senyawa bahan alam yang memiliki potensi sebagai agen hepatoptotektor adalah flavonoid, fenol alkaloid dan terpenoid. Salah satu tanaman yang memiliki kandungan senyawa tersebut adalah tapak liman (Elephatopus scaber L.). Tujuan penelitian ini adalah untuk mengetahui potensi efek hepatoprotektor dari ekstrak etanol herba tapak liman pada rentang dosis 150 mg/kgBB – 300mg/KgBB pada hewan uji tikus wistar jantan yang telah diinduksi agen hepatotoksik berupa isoniazid. Jenis penelitian ini adalah eksperimental laboratorium dengan desain pretest and postest control group dengan menggunakan sebanyak 24 ekor tikus yang terbagi menjadi 6 kelompok, yaitu kelompok I (kontrol normal), kelompok II (isoniazid 50mg/kgBB), kelompok III (kurkuminoid 100mg/kgBB, isoniazid 50mg/kgBB), kelompok IV (tapak liman 150mg/kgBB, isoniazid 50mg/kgBB), kelompok V (tapak liman 300mg/kgBB, isoniazid 50mg/kgBB), dan kelompok VI (tapak liman 450mg/kgBB, isoniazid 50mg/kgBB), yang diinduksi secara peroral selama 14 hari. Pengkuran kadar SGOT dan SGPT dilakukan tiga kali pengulangan pada hari ke 0, 7, dan 14. Hasil pengukuran kadar SGOT dan SGPT pada hari ke-7 secara statistik menunjukkan adanya kenaikan yang signifikan pada kelompok II-VI akibat pemberian isoniazid. Pada hari ke-14, kelompok kontrol positif maupun kelompok ekstrak herba tapak liman secara signifikan mengalami penurunan kadar SGOT dan SGPT yang mendekati nilai normal.

Published: February 2025

Intravenous admixtures are sterile solutions prepared by mixing one or more different drugs with a suitable solvent and given to patients via the intravenous route. One of the factors causing contamination of the intravenous preparation mixture is an error in the aseptic technique during the preparation phase. Errors in aseptic techniques can cause infection. Newborns (neonates) are children under the age of 28 days. During 28 days of birth, have the highest risk of dying. The rate of potential adverse drug events (ADE) is three times higher in children than adults and substantially higher in neonates receiving intensive care. Intravenous admixture therapy, often performed in general wards, is highly susceptible to bacterial contamination which can result from aseptic technique errors. Bacterial contamination in intravenous preparations can cause infection which can trigger septic shock to death. The purpose of this study was to evaluate the suitability of the mixing process and the process of administering intravenous admixture drugs to infant patients. This study was conducted on infant or neonatal patients who were hospitalized in general wards and special intensive wards for babies in hospitals. Dr. Moewardi Surakarta. The research took place from February to March 2020 and was carried out using a prospective observational method.
