Abstract

This research focuses on applying Internet of Things (IoT) technology to measure energy consumption levels to reduce work accidents based on ergonomics. Work accidents caused by ergonomic factors, such as physical fatigue and discomfort, can be overcome by understanding and managing energy consumption in the work environment. Comparisons made between IoT-based approaches and traditional methods, such as manual observation and periodic evaluation, are often less efficient and unresponsive to changes in the dynamic work environment.The research methodology consists of three main stages. First, design and implement an IoT system involving intelligent sensors to measure energy consumption and ergonomic factors. Second, real-time data collection by analyzing data using artificial intelligence algorithms. Third, performance comparison between IoT-based and traditional methods through field trials and statistical analysis. The research results are expected to provide new insights regarding the effectiveness and efficiency of IoT technology in managing the risk of work accidents based on ergonomics. Future implications of this research include the potential for widespread use of IoT technology in various industrial sectors to improve worker safety and well-being. In addition, this research can pave the way for developing more sophisticated technological solutions tailored to the specific needs of each sector.

Abstract

PT. XYZ is a manufacturing company engaged in the manufacture of packaging cardboard. In the production process at PT. XYZ still found the presence of waste, especially in defects, waiting, and excessive transportation. This study aims to minimize or eliminate waste by providing recommendations for improvement using a lean manufacturing approach, then the improvement recommendations are designed through system simulation using proModel software. The lean manufacturing method used in this research is Value Stream Mapping (VSM) to map the entire value stream in the production process from start to finish, where the VSM manufacturing process is supported based on the tools selected from the Value Stream Analysis Tools (VALSAT). Furthermore, to find the root cause of waste, Fishbone Diagram is used, and to determine the cause of the most critical waste, the Failure Mode and Effect Analysis (FMEA) method is used. The results showed that with the improvement recommendations given, the processing time could be reduced from 9743.70 seconds to 6417.15 seconds, and based on the simulation results the improvement showed an increase in the average number of products per month which was 64.26% with an increase from 52962 pcs to 87000 pcs.

Abstract

PT PJB UBJOM and PLTU Pacitan are using steam power to produce electricity called a Steam Power Plan. The process uses a coal-fired boiler to heat water and produces steam (high-temperature water vapor) to turn a turbine. There is always a risk of crushing injuries, electrical shocks and burns, boiler fires, and explosions, and contact with hazardous chemicals in the work environment, which is frequently hot and noisy and involves several large equipment and processes. The objective of this research is to analyze the risk assessment in Boiler systems with Hazard and Operability Study (HAZOP). Additionally, the usual risk matrix was used to quantify and rank the likelihood and severity of each deviation. The five probability and severity categories are divided into four risk assessment levels by the 5x5 risk matrix. This study uses the risk matrix on PT. PJB standard. According to the results of the Hazard and Operability Study (HAZOP) on PT PJB's boiler system, there are two study nodes with extremely high-risk levels: the feed water setting to the steam drum has a damaged feed water pump, and the steam pressure on the steam drum has a damaged safety valve. As a result, the water level is low, and the boiler trips. The controls implemented by PT PJB are pump repair/ replacement, feed water flow sensor, steam drum level sensor, inspection/ safety valve repair, leak check, sensor level, sensor pressure, and safety valve certification.

Abstract

Pemilihan penyedia sangat penting dalam upaya meningkatkan daya saing bisnis. Pemilihan pemasok yang tepat dapat membantu perusahaan mengatasi masalah biaya produksi sehingga perusahaan dapat meningkatkan keuntungannya. Membeli produk dengan harga murah dari supplier karena kualitas barang yang dibeli kurang baik akan menimbulkan keluhan dari pelanggan. Penelitian ini bertujuan untuk memilih supplier terbaik di CV. Saonek Raya dalam kegiatan penyediaan bahan baku bangunan. Terdapat 5 vendor yang akan dianalisis dalam penelitian ini yaitu UD. Sri Rezeki, Toko Gedung Hendra, Toko Gedung Safira, Toko Gedung Sayosa dan Toko Gedung Banjar.Metode yang digunakan dalam penelitian ini adalah Analytical Hierarchy Process (AHP) sebagai metode pemilihan supplier utama dalam penelitian ini. Dari hasil analisis dengan menggunakan metode AHP, Toko bangunan Hendra mendapat skor 2.898, toko bangunan Sayosa mendapat skor 2.100 dan toko bangunan Banjar mendapat skor 7.002. Berdasarkan hal tersebut maka Toko Bangunan Banjar merupakan pemasok terbaik bagi perusahaan dalam mensuplai kebutuhan bahan baku bangunan.

Abstract

PT XYZ has a problem with the delayed arrival of ordered production materials. Although the company is aware of the delays based on data, the company does not yet know the causes or sources of problems that cause delays. On the other hand, not all factors can be controlled to reduce the delay in the arrival of production materials. The company intends to predict the change in delay time if control or intervention is carried out on certain factors by utilising data availability. The factor to be treated is requisition-to-order lead time A causal inference model is used using the Dowhy library (a Python library for causal inference by graphing the model, quantitatively evaluating causal effects, and validating the causal assumptions) to estimate the quantitative causal effect between requisition-to-order lead time and the arrival time of the ordered material by considering other factors that also affect the delay. The results of the causal effect estimation are that by intervening or controlling the requisition-to-order lead time factor by one day, there is a decrease in the average delay in material arrival time by one day

Abstract

In today's competitive business world, organizations are striving to improve their operations and stay ahead. Lean Six Sigma is a popular approach that helps optimize processes and reduce waste. This research focuses on using Lean Six Sigma and TRIZ together to reduce waste in the shuttlecock industry. The study uses a structured process and tools like Value Stream Mapping and Fault Tree Analysis to find and solve waste issues. The results show problems like unnecessary activities, delays, and defects in the production process. Using TRIZ, suggestions for improvements are made based on the analysis. This study shows that combining Lean Six Sigma and TRIZ can effectively reduce waste and improve processes. The findings add to our understanding of using these methods in the shuttlecock industry and offer insights for future research and improvements.
