ABSTRAK Saat ini, peningkatan kesadaran masyarakat terhadap kualitas udara memerlukan solusi monitoring yang efisien dan mudah diakses. Penelitian ini bertujuan untuk membangun sistem monitoring kualitas udara di ruang terbuka dengan memanfaatkan teknologi Internet of Things (IoT) yang terintegrasi dengan Google Sheet. Terdapat empat parameter yang dimonitoring yaitu konsentrasi gas karbondioksida (CO2), konsentrasi gas karbondioksida (CO), suhu, dan kelembaban udara dengan menggunakan ESP32 sebagai pengatur seluruh proses dalam sistem. ESP32 merupakan sebuah modul mikrokontroler dengan fitur mode ganda yakni WiFi dan Bluetooth. Selain itu, sumber energi listrik yang dipakai berasal dari tenaga matahari yang dikonversi menggunakan panel surya. Uji coba system monitoring dilakukan pada pukul 06.30 WIB sampai 22.51 WIB, dimana system instrumentasi di pasang pada ruang terbuka dengan ketinggian 2 m diukur dari permukaan tanah. Hasil uji coba menunjukkan bahwa sistem IoT dapat melalukan pemantauan secara realtime dan efisien dalam mendeteksi variasi setiap detik terhadap parameter kualitas udara yang diukur. Sistem monitoring berbasis IoT dan Google Sheet ini menawarkan solusi monitoring kualitas udara yang hemat biaya, efisien, dan interaktif, serta memudahkan partisipasi masyarakat dalam upaya pemantauan kualitas udara. Kata kunci—Google sheet, Internet of Things (IoT), Kualitas Udara, Monitoring ABSTRACT Nowadays, the increasing public awareness of air quality necessitates efficient and easily accessible monitoring solutions. This research aims to develop an open-space air quality monitoring system by leveraging Internet of Things (IoT) technology integrated with Google Sheet. Four parameters are monitored: carbon dioxide (CO2) concentration, carbon monoxide (CO) concentration, temperature, and humidity. The microcontroller used is the ESP-32, and the electrical energy source is derived from solar power, converted by solar panels. The monitoring system trial ran from 06:30 to 22:51 local time, where the instrumentation system was installed in an open space at a height of 2 meters from the ground level. Trial results show that the IoT system can monitor in real-time and efficiently detect second-to-second variations in the measured air quality parameters. This IoT and Google Sheet-based monitoring system offers a cost-effective, efficient, and interactive solution, facilitating community participation in air quality monitoring efforts. Keywords—Air quality, Google sheet, Internet of Things (IoT), Monitoring system

In order to increase the durability and quality of bananas, this research discusses the design of an economical gas-based dehydrator with the application of PID control for valves and gas, specifically for small and medium-scale home industries. The main objective was to develop a cost-effective and efficient solution for drying bananas without sacrificing nutritional quality and taste. The dehydrator system is designed using PID control to obtain accurate and precise temperatures during the drying process. The algorithm is that the PID control will regulate and adjust how much gas is released through the valve based on the difference between the desired and actual temperature in the drying room. The best constants of PID we get are P = 1, I = 2, and D = 3. By applying these constants, the time taken by the system to change a signal from 30oC to 100oC of temperature is about 5 minutes, with a maximum overshoot of about 10%. In addition, the system required 25 minutes to achieve a steady state with an error value of about 5% from the setpoint. From the results of this experiment, it would be declared that the performance of the dehydrator built has indicated good performance. The minimum temperature that could be generated by the dehydrator is 90oC, while the maximum temperature is set 150oC. The experiment shows that this dehydrator can reduce the water content of a 1-2 g banana fruit by up to 50% within 60 minutes and 26% for a 10 g banana fruit mass simultaneously. The results also show that the dehydrator maintained optimal banana fruit quality based on texture, colour, and taste. Thus, these results indicate the great potential of gas-based dehydrators with PID control as an innovative solution for the home fruit processing industry, offering a combination of efficiency and cost-effectiveness

Penelitian ini mengeksplorasi strategi pengoptimalan penerapan metode 5S (Seiri, Seiton, Seiso, Seiketsu, dan Shitsuke) dalam pengelolaan laboratorium sekolah menengah serta dampaknya untuk meningkatkan sikap ilmiah siswa. Melalui tinjauan literatur yang sistematis menggunakan pedoman PRISMA, kami mencari berbagai artikel dan penelitian terdahulu yang bersumber dari Google Scholar, ScienceDirect. Dari 150 artikel yang ditemukan, 28 penelitian yang memenuhi kriteria inklusi dan layak ditinjau. Kajian ini mengidentifikasi hubungan antara keteraturan laboratorium dan pengembangan keterampilan ilmiah. Hasil analisis menunjukkan bahwa implementasi 5S secara konsisten meningkatkan efisiensi praktikum, membangun budaya kerja yang sistematis, serta memperkuat sikap ilmiah seperti ketelitian, keterbukaan terhadap bukti, dan pemikiran kritis. Tantangan seperti keterbatasan tenaga laboran, minimnya pemahaman tentang prinsip 5S, serta kurangnya pembinaan budaya kerja masih menjadi hambatan dalam optimalisasi metode ini. Strategi edukasi, mentoring, serta integrasi teknologi dalam manajemen laboratorium dapat memastikan efektivitas metode 5S dalam mendukung pembelajaran sains. Penelitian ini memberikan wawasan bagi pengelola pendidikan dalam merancang kebijakan yang mendukung pembentukan budaya kerja ilmiah dan peningkatan kualitas pembelajaran berbasis eksperimen.

Physics laboratories generate large volumes of complex experimental data that require efficient and secure management systems. The integration of Big Data and IoT offers solutions through real-time monitoring, automation, and advanced analytics. However, adoption in educational and small-scale laboratories remains limited due to high costs, data security issues, and technical skill gaps. This study employs a Systematic Literature Review (SLR) method, analyzing 30 articles published between 2017 and 2024 from open-access sources such as Google Scholar and IEEE Xplore. Data extraction focuses on applications, challenges, and synergies of Big Data and IoT in physics laboratory information systems. The findings highlight key applications such as real-time environmental monitoring, automated data collection, RFID-based inventory management, and advanced data analytics. The main challenges identified include high implementation costs, system incompatibility, and a lack of skilled personnel. The synergy between IoT and Big Data enhances accuracy, operational efficiency, and decision-making. This study presents a structured framework of challenges and corresponding solutions, and also highlights underutilized practices such as LIMS integration and adaptive environmental control. The contributions include theoretical insights into the digital transformation of laboratories and practical strategies based on CERN’s case study that are applicable to educational and research labs.
