Abstract

Occupational Safety and Health (K3) is an effort to create a safe, healthy and prosperous work environment, free from accidents, fires, explosions, environmental pollution and work-related diseases. Work accidents can cause losses for workers, employers, government and society, which can include loss of human life, damage to property and the environment. For this reason, concrete steps need to be taken to prevent and reduce the occurrence of work accidents as much as possible. One of the conditions where work accidents can occur is in the educational environment. The research uses descriptive methods with the aim of identifying the types of work accidents and how to overcome them that can occur. Based on the research results, it was concluded that occupational safety and health are very important, potential accidents in the Akmet environment can be identified. By using the HIRADC method, potential hazards can be identified and controls that must be implemented, such as using elimination methods to creating a quality manual and creating procedures for academic activities. This research has produced a draft Quality Guide for Occupational Safety and Health as well as procedures for academic activities in the Akmet environment.

Abstract

Tangki Ukur Mobil merupakan suatu jenis tangki yang digabungkan dengan sebuah kendaraan sehingga tangki ukur ini bisa dipindahkan dari satu tempat ke tempat lainnya dengan mudah. TUM termasuk UTTP yang wajib ditera/ tera ulang setiap dua tahun sekali. Dalam pengujian TUM, terdapat penentuan indeks penunjuk dengan cara mengukur tinggi cairan (t2) dan jarak permukaan cairan hingga manhole atau ketinggian ruang kosong (t1). Kegiatan tersebut jika dilakukan secara manual kurang praktis, karena harus mencari posisi batas tercelupnya dip stick di dalam zat cair tersebut untuk mengetahui tinggi cairan dan menggunakan salib ukur untuk mengukur jarak ruang kosong. Selain itu juga memungkinkan terjadinya kesalahan pembacaan skala (paralaks) pada alat ukur yang digunakan. Dikaitkan dengan efisiensi dan pemenuhan kebutuhan, pengukuran ketinggian indeks pada tera/tera ulang TUM menjadi hal penting untuk dilakukan. Dengan demikian dibuatlah prototipe berbasis teknologi Internet of Things (IoT) yang dapat diakses melalui aplikasi Blynk, mampu memberikan hasil secara realtime. Komponen yang digunakan berupa modul WiFi ESP32 sebagai transmitter yang dipadukan dengan sensor ultrasonik HCSR-04. Sensor ultrasonik ini akan mendeteksi ketinggian indeks pada TUM dengan memanfaatkan gelombang ultrasonik. Hasil pengujian menunjukkan bahwa prototipe ini memiliki rata-rata error 1,29% dan akurasi 98,71%. Sistem ini diharapkan dapat memberikan kontribusi dalam mempermudah kegiatan tera/ tera ulang TUM secara efektif dan efisien.

Abstract

Manual water quality monitoring in accordance with Minister of Health Regulation No. 2 of 2023 is urgently needed to detect early physical, chemical, microbiological, and radioactive contamination that could potentially endanger public health.. This water certainly has certain qualities, including its turbidity level. In accordance with Ministry of Health Regulation No.2/2023, the maximum turbidity limit for sanitary water is below 3 NTU. Therefore, a device is needed that can monitor the turbidity level of water practically. The purpose of this study is to design a prototype device for monitoring the turbidity value of sanitary hygiene water in accordance with Permenkes No. 2 of 2023. This study used the Analysis, Design, Development, Implementation, and Evaluation method. This method is expected to produce a structured and systematic approach to the development and design of the prototype that will be created. The prototype design process uses a TS 300B turbidity sensor to detect turbidity, NodeMCU ESP8266 as a microcontroller and IoT, and a 128x64 I2C OLED display. The application of IoT in this prototype is based on the use of a website to display and store measurement data. Testing was conducted on the TS 300B turbidity sensor on three samples with three repetitions, compared to the standard Nephelometric Turbidity Unit (NTU) solution. The test results showed an average accuracy and precision of 99.76% and 99.72%.  Currently, some of the detection device models on the market have an accuracy of between 0-200 NTU with the added feature of data connectivity, but they are relatively expensive.Therefore, in the future,  the role of IoT-based technology will be further optimized, with the aim of improving the quality of life for all
