Abstract

The current rapid technological advancement allows companies to increase production speed through the use of machinery. However, this often leads to monotonous and physically demanding work, especially in Manual Material Handling (MMH) activities. Inappropriate MMH activities can result in Musculoskeletal Disorders (MSDs), involving disruptions to muscles and joints. To address this issue, the design of ergonomic work aids is necessary.The NIDA method (Need, Idea, Decision, Action) is employed to design work aids by considering needs, innovative ideas, design decisions, and implementation actions. The REBA method (Rapid Entire Body Assessment) to assess the working position or posture of an operator’s neck, back, arms, wrists, and legs . Research results indicate that the use of specialized aids in activities such as measurement can reduce MSDs complaints, where the score on employee body posture analysis is obtained on averange 3 and the NBM questionnaire date shows an averange score of 30, whwere this score included in the low risk category. And before the work facility design was carried out, the score was for REBA 6 and with NBM questionnaire data 41, the category indicates medium risk. Previous research has also utilized the NIDA method in designing work aids with positive outcomes. In conclusion, the use of the NIDA method in designing ergonomic work aids can alleviate MSDs complaints and enhance productivity at PT Citra Tubindo TBK and similar industries.

Abstract

Cigarette smoke not only reduces indoor air quality but is very dangerous for the health of both those who smoke and those around them. The chemicals contained in cigarette smoke can cause disease to attack the body. Several actions to reduce the impact of cigarette smoke, such as the government's policy of making pictures of mouth cancer on cigarette packs, writing and pictures prohibiting smoking are often ignored by smokers so they are still seen smoking in public places. Previous research showed that monitoring systems in the form of SMS text messages and website-based applications were still deemed to be less effective. Therefore, in this research, a cigarette smoke detector was built in a closed room using the MQ-2 sensor and the SHARP GP2Y1010AUOF smoke sensor as a smoke detector and controlled using Arduino Uno and NodeMCU V3. Sensor reading values are sent using an internet connection then stored in real time in the Firebase database and displayed on the Android smartphone application. If the sensor detects cigarette smoke, the application provides a notification on the application and a buzzer sounds on the device.

Abstract

Data security is a crucial aspect in today's digital era, especially with the increasing exchange of information over the network, so network security seeks to secure from physical and logical dangers and threats that can steal personal data. This research aims to analyse and design a text data security system by utilising the Secure Hash Algorithm (SHA) cryptographic algorithm in order to increase the level of security and integrity of text data through the application of reliable cryptographic technology. The research method used is Secure Hash Algorithm (SHA) 256 to analyse text data, and later the text data will be processed using the SHA 256 application to find out how it works and its implementation on securing text data. The results for how SHA works have a predetermined initial value for each hash literacy generated from several prime numbers, the message to be hashed is divided into smaller blocks, each of which has a length of 512 bits and padding is done so that the length of the text can be divided by 512 which later for each text block is processed repeatedly for 64 rounds, after all text blocks are processed, the resulting hash value is a series of bits with a certain length. The results for the SHA implementation steps are first to take the text data to be secured, then convert the text data into ASCII/Unicode format, run the SHA algorithm to find the hash value, save the hash value into the database, then verify the authenticity of the text data, run the SHA algorithm on the data and compare the hash value generated with the hash value previously stored, if the result is the same, then the text data is original. Recommendations that can be given are to explore and develop the blockhchain side and improve the SHA 256 application in the testing section.fritzing.

Abstract

The research proposes an IoT-based temperature alarm system addressing challenges in maintaining precise enclosure temperatures for reptile husbandry. The system, utilizing the DHT11 temperature sensor and Blynk platform, enables remote monitoring of reptile enclosures. When temperatures deviate from the desired range, the sensor transmits data to the system controller, which, in turn, sends warning notifications to users' smartphones. This prototype empowers users to make timely adjustments, such as deactivating UV lamps or activating fans, to maintain optimal enclosure temperatures. Ultimately, the system offers a practical solution for reptile caretakers, ensuring the well-being of reptiles by closely mimicking their native habitats through effective temperature control.

Abstract

The temperature in the room in the milling section reaches 37'C which is not in accordance with the limit of room temperature regulations. Employees who are too tired to work with hot room conditions make work concentration unfocused and can endanger the workers themselves. The purpose of this study is to determine the state of room temperature at PT Team Metal Indonesia, determine the concentration of working employees at PT Team Metal Indonesia and the relationship between room temperature and concentration of working employees at PT Team Metal Indonesia. This study uses a simple regression method. Based on the results of the study, it is known from the measurement of room temperature that the average value is 39.77 and the percentage value is 79.54%. This value is not good at the room temperature in the company. It is known from the measurement results on work concentration that the average value is 40 and the percentage value is 80%. This value is not good for the concentration of work felt at the company and there is a significant influence between room temperature and work concentration on milling department employees at PT Team Metal Indonesia.

Abstract

The use of computers began for typing until now computers can become tools that imitate the work of the human brain. The watermelon plant is a fruit plant generally used by Indonesian people. However, watermelon plants are plants that are susceptible to disease attacks. To be able to manage the plants well, farmers need to make efforts to deal with them, both in selecting seeds and increasing production. The source of the problem is the fact that watermelon plants are very susceptible to plant diseases which can and do attack at any time, whether from sprouting or sowing seeds until harvest time. Therefore, this research was carried out by creating an expert system application that provides information about diseases that attack watermelon plants and identifies disease symptoms based on physical characteristics so that the expert system application can help farmers in dealing with diseases and can provide solutions to overcome them. Expert systems are a branch of artificial intelligence that can help humans to solve various problems as if the human were an expert who can solve problems. From this research it can be concluded that the expert system designed can provide accurate diagnoses using the forward chaining.
