Abstract

Basically, product quality is one of the important factors that becomes one of the benchmarks for the success of a product and the future of a company. Even though the production process is carried out well, the resulting product is often not as desired, or in other words it produces a damaged/defective product. The presence of defective products will reduce product quality and this causes losses to the business. To meet consumer satisfaction, business actors must be able to maintain product quality in accordance with consumer needs, in quality control which is very much needed to control the production process so that it conforms to predetermined standards. Small and Medium Industrial Factory (IKM) Bapak Warianto is one of the tempe production factories where in the tempe production process he found several tempe defects ranging from color, shape, to the packaging of the tempe that could not be sold. This research, which was conducted at tempe factory Bapak Warianto, aims to identify quality problems in tempe products, analyze the causal factors in tempe products and provide solutions to improve the tempe production process. The Seven Tools Method is the method that will be used in this research, where this method consists of several statistical tools that are used to determine product quality. From 10 sampling times, there were 4 types of defects in tempeh, of which the four types of defects were eaten as the most dominant/frequent defects. This is because the storage area for tempeh when fermented is not clean and not covered enough so that small animals can still enter. Lack of air circulation and human factors where workers are not careful are also some of the causes of damage to tempe.

Abstract

This research develops an Internet of Things (IoT)-based smoke detection system using MQ135 and DHT22 sensors integrated with WhatsApp chatbot via HTTP protocol. The system is designed to provide real-time notifications related to air quality, including gas concentration, temperature, and humidity. The test results show accurate and stable sensor performance in detecting environmental parameters. Evaluation is done through Quality of Service (QoS) analysis based on delay, jitter, packet loss, and throughput parameters. The test shows a fairly high network stability with 0% packet loss and an average throughput of 2045.53 Kbps, which falls into the Excellent and Good categories. However, the average delay of 2173.65 ms and jitter of 254.11 ms were classified as Poor, indicating the need for improvement in the responsiveness aspect. This research is expected to contribute to the integration of air quality monitoring systems with practical and easily accessible instant messaging services. The system offers an innovative solution for real-time smoke detection and early warning. Limitations of this study include limited data size and room for improvement in the interpretability and scalability of the system for wider IoT implementation.
