Farmers risk of posture injury when operating a tractor. The RULA (Rapid Upper Limb Assessment) is one methods used to investigate the risk of abnormalities will be experienced in carrying work activities. This research is to analyze the risk of farmers' posture when using paddy plow tractor seat. The risk of farmers' posture when driving a rice plow using results seat on paddy field plow is dominantly green, which means the posture is acceptable, where the final score value in the RULA analysis output results is 2, which means the worker works with a posture that has no risk injury.</p> Rossi S Wahyuni Mei Raharja Yuyun Yuniar Rohmatin Adil Areza Copyright (c) 2024 Jurnal Ilmiah Teknik 2024-05-08 2024-05-08 3 2 01 06 ANALISA KEKUATAN TARIK PADA HASIL PROSES PENGECORAN NOZZLE UNTUK BRAKE COUPLING MENGGUNAKAN METODE CETAKAN PASIR JOLT SQUEEZE http://journal.admi.or.id/index.php/JUIT/article/view/1316 <p>Sand casting is one of the metal casting methods that has been developed and is still being improved. Sand casting is a type of metal casting that use sand molds. There are several ways to make sand casting, However, this study use the jolt squeeze technique to create complex product forms such as the nozzle component of the air brake coupling. FCD 500 nodular cast iron alloy castings are used in the production of brake coupling nozzles. The goal of this research focuses on the metal casting technique for nozzle products for brake coupling, and then continue with the tensile testing procedure. Tensile testing utilizing JIS Z 2201 standards with two sampels with different diameters, specifically 12,46 mm and 12,79 mm, and material types FCD 500-1 and FCD 500-2. The research results show the sequence of the nozzle metal casting process for brake couplings, through the stages of designing, constructing models and cores, making molds, melting, pouring, fettling and finishing, and quality control. Tensile stress values of 525 N/mm<sup>2</sup> and 546,189 N/mm<sup>2</sup> were obtained for each FCD 500-1 and FCD 500-2 sampels, with force loads of 64000 N and 70130,66 N, respectively.</p> Aji Abdillah Kharisma Abdul Rahman Agung Ramadhan Copyright (c) 2024 Jurnal Ilmiah Teknik 2024-05-08 2024-05-08 3 2 07 16 10.56127/juit.v3i2.1316 PEMANFAATAN TELEGRAM UNTUK PENDETEKSI KEBOCORAN GAS BERBASIS NODEMCU http://journal.admi.or.id/index.php/JUIT/article/view/1339 <p>A significant increase in consumption of natural resources in the household sector is the use of LPG (Liquefied Petroleum Gas) gas, this can increase the risk of fire due to leaks from gas cylinders.&nbsp;&nbsp;&nbsp; These gas leaks are often unknown to users because not all LPG cylinder manufacturers provide a security system for the LPG cylinders they sell, so not all homes have gas leak sensors on LPG cylinders, therefore a tool is needed to detect LPG gas leaks. In view of these problems, in this research a device was created that can detect gas in a room with an MQ-2 sensor and apply a notification system using Telegram as an SMS notification sender and a buzzer as an alarm. The design of this detection tool as a whole is controlled by the NodeMCU ESP8226. During system testing, when a gas leak is detected at a distance of 1cm – 100cm with the MQ-2 sensor, the system will provide a notification via Telegram and activate the alarm (the buzzer will beep). The process of sending this message takes around 4-6 seconds. The tool was also tested on two different cellphones and obtained the expected results and good performance.</p> Tri Sulistyorini Nelly Sofi Erma Sova Copyright (c) 2024 Jurnal Ilmiah Teknik 2024-05-08 2024-05-08 3 2 17 27 10.56127/juit.v3i2.1339
