Transformator daya adalah peralatan penting pada sistem tenaga listrikkhususnya pada penyaluran energi listrik. Dalam penyaluran energi listrikkeberadaannya sangat berpengaruh terhadap kontinuitas pelayanan. Salahsatu faktor yang mempengaruhi umur pemakaian transformator adalah panasyang timbul akibat pembebanan transformator dan suhu sekitar (ambienttemperature). Pada penelitian ini dilakukan sebuah perhitungan dan analisispengaruh pembebanan terhadap susut umur transformator daya pada PT.SUMBER SEGARA PRIMADAYA unit 1. Berdasarkan hasil dari penelitianini diperoleh penyusutan umur transformator terbesar yaitu 0,197 per unitdengan perkiraan sisa umur sebesar 48,27 tahun dan penyusutan umurtransformator terkecil yaitu 0,035 per unit dengan perkiraan sisa umursebesar 266,89 tahun. Nilai perkiraan sisa umur tersebut masih diatasstandarnya yaitu 20,55 tahun berdasarkan standar IEEE C57.91 1999, denganmengetahui perkiraan sisa umur transformator tersebut maka dapat mencegahkerusakan dengan mengganti transformator sebelum terjadi kerusakansehingga kontinuitas pelayanan tetap terjaga

This research is based on the Regulation of the Nuclear Energy Supervisory Agency of the Republic of Indonesia Number 2 of 2018 concerning Conformity Tests for Diagnostic and Interventional Radiology One component that must be tested with a minimum passing standard of ≥ 100 lux at a distance of 100 cm. Data collection is obtained at the Calibration Agency to obtain accurate results. The purpose of this tool, the Lux Meter is equipped with a distance sensor to measure the light intensity of a collimator lamp with an intensity that must be ≥ 100 within a distance of 100 cm from the light source. So, making a tool that can be used to measure the amount of collimator illumination is accompanied by measuring the distance, so that it can ensure the results are in accordance with the limits that have been determined with a Lux Meter equipped with a distance sensor using the BH1750 module and the HC-SR04 module. For testing the tool made, it was compared with a Standard Lux Meter with the HIOKI brand, an average error value of 0.021 at a distance of 50cm, an error of 00.020 at a distance of 100cm, and an error of 0.022 was obtained, while for testing the distance sensor it was compared with a Standard Meter with the FLUKE brand. The average percentage error value is 0.002 at a distance of 50cm, an error of 0.011 at a distance of 100cm, and an error of 0.008 at a distance of 130cm.

To support green energy and reduce the effects of greenhouse gases, it is necessary to conceptualize and explore the use of renewable energy. In this research, the use of new renewable energy, especially photovoltaics (PV), will be applied to educational buildings, especially at ITS PKU Muhammadiyah Surakarta. This system is intended to reduce the use of conventional electrical energy. This system will be installed on the roofs of campus buildings with installation plans to meet the power requirement of 4.8 kW. This photovoltaic (PV) system will be modeled to determine the number of PV panels needed. Based on the simulation results, the number of panels required is 36 panels (2 series, 18 parallel) to produce 4.85kWh of power. Modeling and analysis of this system was carried out using RETScreen and MATLAB SIMULINK software.

A thermohygrometer is a device used to measure temperature, humidity, and the concentration of medical gases (CO and CO₂) in operating rooms. The temperature in an operating room should be maintained between 19°C and 24°C, and humidity between 45% and 65%, to prevent damage to electronic equipment and corrosion caused by low temperatures and high humidity. Medical gases containing oxygen can also accelerate corrosion. Therefore, a thermohygrometer equipped with medical gas readings is necessary. This study aims to design a thermohygrometer using a DHT22 sensor to measure temperature and humidity and an MQ-135 sensor to detect CO and CO₂ gases. The obtained data is displayed on an I2C LCD screen and sent to the Blynk application via WiFi using an ESP32. Testing shows a temperature reading error of -0.02%, humidity -0.02%, CO gas 0.32%, and CO₂ -0.16%, all within a tolerance limit of ±5%.

Thermohygrometer is a tool that functions to measure room temperature and humidity. The temperature and humidity in the operating room are set in the temperature range of 19˚C - 24˚C and humidity of 45% - 65%. Therefore, the operating room requires a good temperature and humidity control system to avoid damage to electronic components due to temperatures that are too low and humidity that is too high which causes corrosion. In addition, the influence of high concentrations of medical gas accelerates the rate of corrosion. Because medical gas consisting of CO and CO₂ gas contains oxygen as an oxidant gas. Therefore, a tool such as a Thermohygrometer is needed but equipped with a medical gas reading. This tool aims to read the conditions of temperature, humidity, and medical gas (CO & CO₂) so that it can be analyzed by Electromedics to regulate the air conditioning system. In addition, a Thermohygrometer system is made to allow data access from outside the operating room. The Thermhygrometer tool is made using two sensors, namely DHT22 and MQ-135. DHT22 is used to read temperature and humidity parameters, while the MQ-135 sensor is used to read the concentration of CO and CO₂ gases. The reading results are displayed on the I2C LCD screen. The components are integrated with ESP32 for data processing and as hardware that can be used to create a WiFi connection system. WiFi connectivity is needed to send data to the Blynk application. Testing by calibrating the DHT22 sensor and testing the suitability of the MQ-135 sensor with the gas analyzer. Based on the tests carried out, the temperature error value was obtained at -0.02% and humidity at -0.02%. While the error value was 0.32% for CO gas and -0.16% for CO₂ gas. The error value is still within the tolerance limit

Peralatan Peralatan kesehatan merupakan komponen penting dalam peningkatan mutu pelayanan, sehingga diperlukan manajemen yang baik untuk menjamin keamanan dan efisiensi penggunaannya. Pengelolaan yang kurang tepat dapat menurunkan kualitas layanan dan membahayakan pasien, sehingga diperlukan intervensi edukasi berupa penyuluhan bagi tenaga kesehatan. Penelitian ini bertujuan mengetahui efektivitas penyuluhan manajemen peralatan medis dalam menurunkan kesalahan pengelolaan di Puskesmas Jayengan Surakarta. Penelitian menggunakan desain kuasi-eksperimental pre-post test one group tanpa kontrol dengan sampel total 30 tenaga kerja. Intervensi berupa penyuluhan selama 1 jam meliputi perencanaan, pengoperasian, pemeliharaan, kalibrasi, dan penghapusan peralatan. Instrumen berupa kuesioner 15 soal pre-test dan post-test, dianalisis menggunakan uji Wilcoxon Signed-Rank. Hasil menunjukkan rata-rata kesalahan menurun dari 3,03 menjadi 0,83 atau sebesar 72,5%, dengan p-value = 0,0000 yang menandakan perbedaan signifikan. Dengan demikian, penyuluhan manajemen peralatan medis terbukti efektif meningkatkan pemahaman tenaga kesehatan dan disarankan dilakukan rutin sebagai pengabdian masyarakat untuk mendukung mutu pelayanan.
