MONITORING ALAT PENGUKUR SUHU RUANG UNTUK PENYANDANG TUNANETRA DENGAN SISTEM KELUARAN SUARA BERBASIS MIKROKONTROLER ATMEGA328
Get PDFThis research results in the design of a room temperature measuring device for the blind using the Atmega328 microcontroller. The design of the tool uses the Thermistor NTC 3950 temperature sensor. The sensor input is converted into a digital signal and processed by the Atmega 328 microcontroller using the Arduino Nano programming language. The results of measuring the temperature value of a classroom with an area of 6.8 x 5.5 m for the blind in SLB show that the temperature value is in the range of 26 – 29o. The accuracy of the instrument is measured by comparing a standard measuring instrument with a digital thermometer TPM-10. Observation of room temperature values was carried out for 10 hours in the reading range of values per 1 hour. From the results of a comparison with the standard digital thermometer TPM-10 measuring instrument, it shows that the accuracy of the tool is 98.35%

Abstract: Evaluation of defect in Hydraulic spare-part production process Based on Failure Mode and Effect Analysis approach. The growth of truck-type commercial vehicles has led to innovation in adding a hydraulic system. UD. RZ is a supplier of dump truck hydraulic spare parts. The producer has been observing a comprehensive solution to reduce defects in the production process of hydraulic spare-part. This study aims to evaluate failures along the production process of hydraulic axles using the Failure Mode and Effect Analysis approach. This study begins with mapping the flow of the production process in order to identify product defects, determining the scale of occurrence, severity, and detection by employees and business owners, calculating risk priorities, and mapping the causes and effects of 5M-based defects. This study result distinguished the two topmost Risk Priority Numbers, which scored 224, namely miscalculation in the measurement process and drilling point errors, with a score of 147. The defect has been studied, and found factors such as inaccuracy in work, and the lack of drilling point tools. The solution can be done by re-turning, increasing the accuracy of workers, adding workers' SOPs, and having drilling point tools. The solution is expected to reduce defects in producing hydraulic spare-part of dump trucks.

PERANCANGAN ALAT BANTU PEMETIK DAUN TEH UNTUK MENINGKATKAN PRODUKTIVITAS DAN MENGURANGI RISIKO MUSCULOSKELETAL DISORDERS (MSDs) MENGGUNAKAN METODE ERGONOMIC FUNCTION DEPLOYMENT (EFD)
Get PDFIndonesia merupakan salah satu negara dengan kekayaan dan hasil alam terbesar di dunia. Sebagian besar hasil alam di Indonesia dimanfaatkan untuk keperluan masyarakat dan penggerak perekonomian Salah satu hasil alam Indonesia yang menjadi komoditas adalah teh. PT. XYZ merupakan perusahaan yang bergerak di bidang pengolahan daun teh. Produk yang dihasilkan oleh PT. XYZ adalah teh hijau (green tea). Dalam memenuhi permintaan, PT.XYZ mengalami kendala pada waktu-waktu tertentu seperti pada musim penghujan. Di musim penghujan daun teh cenderung mudah terserang hama atau penyakit seperti penyakit cacar daun yang disebabkan oleh Basidiospora Exobasidium Vexans. Parasit tersebut berkembang pada embun (kabut setelah hujan), air hujan, dan pada temperatur rendah sehingga salah satu hal solusi yang dapat dilakukan adalah dengan memetik teh lebih awal dan dengan cepat sebelum daun teh terserang hama atau penyakit. Akibat menggunakan alat tradisional saat proses pemetikan daun teh terdapat beberapa permasalahan seperti produktivitas pemetikan dan gangguan yang berisiko menyebabkan Musculoskeletal Disorders (MSDs). Untuk menindak lanjuti hal tersebut, penelitian ini bertujuan membuat rancangan alat bantu pemetik daun teh menggunakan metode Ergonomic Function Deployment (EFD) sehingga rancangan alat bantu pemetik daun teh pemetik daun teh yang dibuat dapat meningkatkan produktivitas pemetikan serta rancangan alat yang sesuai dengan aspek ergonomi (ENASE)
