Penyelenggaraan makanan di pondok pesantren berasrama berisiko mengalami kontaminasi mikrobiologis karena makanan diolah dalam jumlah besar dan dikonsumsi secara kolektif. Pemilihan lokasi penelitian diperkuat oleh temuan bakteri Escherichia coli pada air minum di lingkungan pondok, yang menunjukkan potensi cemaran pada media konsumsi. Penelitian ini bertujuan menganalisis hubungan personal hygiene penjamah dengan keberadaan bakteri Escherichia coli pada makanan di dapur pondok pesantren. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian observasional analitik dan desain cross sectional. Penelitian dilakukan di dapur Pondok Pesantren Darul Hijrah Puteri, Cindai Alus, Martapura. Sampel penelitian terdiri dari 7 orang penjamah makanan dan 21 sampel makanan yang diperoleh melalui tiga kali pengulangan observasi dan pengambilan sampel. Hasil penelitian menunjukkan bahwa sebagian besar personal hygiene penjamah makanan memenuhi syarat, yaitu sebanyak 16 observasi (76,2%), sedangkan 5 observasi (23,8%) tidak memenuhi syarat. Hasil pemeriksaan laboratorium menunjukkan bahwa 18 sampel makanan (85,7%) memenuhi syarat terhadap keberadaan Escherichia coli, sedangkan 3 sampel (14,3%) tidak memenuhi syarat. Hasil uji Fisher’s Exact Test memperoleh nilai p-value sebesar 0,008. Kesimpulan penelitian ini menunjukkan bahwa terdapat hubungan yang signifikan antara personal hygiene penjamah makanan dengan keberadaan bakteri Escherichia coli pada makanan di dapur Pondok Pesantren Darul Hijrah Puteri. Penerapan personal hygiene yang belum konsisten dapat meningkatkan risiko kontaminasi makanan. Pondok pesantren disarankan melakukan pemantauan rutin, serta penguatan penggunaan alat pelindung diri selama proses pengolahan makanan.
Pemanfaatan sampah plastik sebagai bahan baku alternatif pada material konstruksi merupakan salah satu strategi pengurangan sampah plastik yang terus dikembangkan. Namun, penggunaan material berbahan dasar sampah plastik berpotensi menjadi sumber pelepasan mikroplastik ke udara yang dapat memengaruhi kualitas lingkungan dan kesehatan manusia melalui jalur inhalasi. Penelitian ini bertujuan untuk menganalisis kuantitas mikroplastik di udara pada bangunan berbahan dasar sampah plastik dibandingkan dengan bangunan kontrol tanpa bahan dasar sampah plastik. Penelitian deskriptif komparatif dilakukan menggunakan 2 model bangunan miniatur yang terdiri atas bangunan kontrol dan bangunan berbahan dasar sampah plastik. Pengambilan sampel mikroplastik udara dilakukan menggunakan penyedot udara selama 60 hari periode pengamatan, dan dianalisis secara mikroskopis untuk menentukan kuantitas mikroplastik berukuran ≥2,5 µm. Data disajikan secara deskriptif berdasarkan nilai minimum, maksimum, rerata, dan standar deviasi. Mikroplastik ditemukan pada sampel udara bangunan bangunan kontrol antara 11-28 partikel/sampel dengan rerata 22,00 ± 3,99 partikel/sampel. Sementara itu, pada kelompok perlakuan berbahan dasar sampah plastik (n=60), kuantitas mikroplastik udara berkisar antara 26-72 partikel/sampel dengan rerata 38,78 ± 9,78 partikel/sampel. Hasil penelitian menunjukkan bahwa rerata kuantitas mikroplastik pada bangunan berbahan dasar sampah plastik lebih tinggi dibandingkan bangunan kontrol. Kesimpulan: Bangunan berbahan dasar sampah plastik menghasilkan kuantitas mikroplastik udara yang lebih tinggi dibandingkan bangunan tanpa bahan dasar sampah plastik. Temuan ini mengindikasikan bahwa material konstruksi berbahan dasar sampah plastik berpotensi menjadi sumber pelepasan mikroplastik ke udara. Penelitian lanjutan diperlukan untuk mengidentifikasi karakteristik mikroplastik serta mengevaluasi risiko kesehatannya pada kondisi bangunan yang lebih representatif.
Purpose – This study aims to optimize the function of sharps containers in preventing needlestick injuries (NSIs) among nursing students during laboratory practice sessions. Design/methods/approach – This study employed a quasi-experimental design using a one-group pretest–posttest approach. The intervention consisted of optimizing sharps container utilization through: (1) standardization of container availability at each practicum table, (2) implementing a maximum fill limit of 75%, (3) ergonomic placement of containers, and (4) training on proper usage. The sample comprised 86 second-semester nursing students selected through purposive sampling. Data were collected through observations of sharps disposal behavior, knowledge questionnaires, and documentation of NSI incidents. The Wilcoxon signed-rank test was used to analyze differences before and after the intervention. Findings – Students’ compliance in using sharps containers increased significantly from 68.5% to 92.3% (p < 0.001). The practice of needle recapping decreased from 45.2% to 12.7%. The incidence of NSIs during laboratory sessions decreased from 8 cases (9.3%) in the pre-intervention period to 1 case (1.2%) in the post-intervention period. Students’ knowledge regarding sharps waste management improved from a mean score of 68.4 to 89.7 (p < 0.001). Research implications/limitations – This study was limited to a single institution with a relatively short observation period (2 months per phase). Further research using a controlled design and longer observation periods is required to assess the generalizability and sustainability of the findings. Originality/value – This study provides practical contributions to the development of standard operating procedures for sharps waste management in nursing education laboratories and serves as a foundation for occupational safety policies for students as future nurses.
Digital thermometers are measuring instruments needed to perform temperature measurement actions and must be calibrated periodically according to standard measurement methods. The purpose of developing this tool is to add PID control to the calibration media where PID control aims to regulate the stability of the temperature setting to be achieved. This is achieved by studying and evaluating the effect of temperature stability on the heater and LM35DZ temperature sensor. This research method uses the Arduino Nanosystem for data processing and PID system control. The LM35DZ temperature sensor on the heater is regulated by a 2 Channel SSR module using a PID system then the temperature generated by the heater will be read by the LM35DZ and displayed on the LCD. The results of this study, digital thermometer calibrator measurements have been successfully carried out by comparing 3 digital thermometers with different brands, namely Omron 343F, Omron 245, and ThermoOne. The difference in error values in oil media is 3-4% and in water media 2-4% with the value of time stability in water media for 3-3.3 minutes and in oil media for 1-2 hours. With this comparison of calibration media, it is hoped that it can help in measuring temperature with better and more effective results. find methods, results, conclusions.
The Positive End Expiratory Pressure (PEEP) parameter is a parameter that must be considered in the process of determining the patient's condition, a safe threshold, and must be in accordance with the settings. However, often the PEEP value on the ventilator does not match the settings so that the measuring instrument capable of detecting PEEP on the ventilator is the Flow Analyzer. The purpose of this study was to design a Flow Analyzer using the MPX2010 sensor to analyze the stability of the PEEP parameters on the ventilator. This study used PEEP settings of 0, 5, 8, 11, 14, 17, 20, 23, 26, and 29 cmH2O. Data were collected using a ventilator with VCV (Volume Control Ventilation) and PCV (Pressure Control Ventilation) modes. The tool used for reference from standard measurements uses the Standard Flow Analyzer tool. The results of this study indicate that the measurement accuracy of PEEP parameters with the Flow Analyzer module at each PEEP setting has the smallest error of ±0% at 0 cmH2O setting so that it also has the smallest value of 0 by standard. deviation and uncertainty (UA) value 0 at each setting. The Flow Analyzer measurement module has the largest error in the 5 cmH2O setting, which is ±13.2% with the largest correction value of 0.77. From the data obtained, it can be said that the monitoring of the PEEP parameter is quite stable even though the value is still out of tolerance. Monitoring of PEEP stability parameters can be implemented during the ventilator calibration process which needs to be carried out to analyze damage and reduce the time of damage to the ventilator.
