Abstract

Export means transporting or bringing goods and services from one country to another coun-try. In order to evaluate how strong export competitiveness is and identify market opportunities, specific calculation methods and approaches regarding comparative advantage are needed. One of them is using the "revealed comparative advanced" (RCA) method, which provides an accu-rate picture of how competitive a product is in the international market. One measuring tool is the Balassa index, where a value of more than one (>1) indicates a strong level of competitive-ness for export products to the destination country. Conversely, a value less than one (<1) indi-cates low competitiveness and sales difficulties in that market. The calculation results show that Timor Leste has an average Balassa index of 60.685, followed by Brunei Darussalam with a Balassa index value of 12.526 and Malaysia of 4.987 and with a stable value, thus indicating good potential for exporters who want to market coffee products. roast them to the country. However, Thailand has little potential with a Balassa index of 1.944. In contrast, Singapore and the Philippines have an average Balassa index below 1, indicating there is no great potential as a profitable export market.

Abstract

Workshop PT. XYZ is a part of a company that carries out activities in the field of maintenance and repair, especially hydraulic, pneumatic and lubrication equipment. These workshop activities include welding activities, operating machine tools and other mechanical work. This study aims to determine the value of the potential risk of occupational hazards and the level of risk of potential occupational hazards at PT. XYZ in the workshop area. This study uses an approach with the HIRA (Hazard Identification and Risk Assessment) method to determine the value of the risk of occupational hazards and the level of risk of potential occupational hazards. The results obtained by using HIRA (hazard identification and risk assessment) were obtained as many as 29 risks which were classified based on potential hazards, namely 28% extreme risk, 41% high risk, moderate risk of 31% and there is no low risk. Improvement recommendations are made based on the level of extreme risk (extreme risk) and high risk (high risk) to prevent and reduce the level of risk of work accidents in the workshop area, while for the moderate risk level, the mitigation recommendation is to supervise the work and make an SWI (simplified working instruction) to make it easier for workers to understand safe and correct work procedures.

Abstract

A collection of shoes that are not neatly arranged often makes you lazy to tidy up and clean them, whereas the condition of scattered shoes can spoil the view and reduce the durability and functionality of the shoes themselves. On the other hand, plastic waste, especially plastic bottles, is increasing and becoming a serious problem for the environment. In an effort to reduce the impact of pollution and utilize unused items, this study proposes a solution in the form of making a shoe rack from used plastic bottle waste. The use of plastic bottles not only reduces the amount of waste but also provides a practical solution for more organized shoe storage, especially for students who need efficient and environmentally friendly shoe storage space. The method used in this study is (R&D), which aims to develop a shoe rack product and test its effectiveness and feasibility. The test results show that this shoe rack can accommodate 12 pairs of shoes with a maximum strength of 5.5 kg per rack consisting of three levels. The use of 69 plastic bottles for the base and 24 bottles for the walls provides a large enough capacity to store shoes. Based on the test results, this shoe rack not only functions as a place to store shoes, but also as an effort to reduce plastic waste and support environmental sustainability. This product can also be used as an example in learning product design, recycling, and entrepreneurship.

Abstract

All companies hope for an effective and efficient production system, but an imperfect production system means that PT XYZ must improve its production activities. The company strives to produce good products followed by a high level of productivity. In this research, we investigate a case at PT XYZ which produces hot stamping foil in the rewind section. This research found that there was waste that occurred in set-up replacement activities in production. Because it requires a long processing time, we perfected the system by implementing the Single Minute Exchange of Dies (SMED) method, then the process optimized internal activities in the set-up process. The application of the SMED concept is carried out by changing internal activities into external activities with the addition of helpers. This research aims to provide a more effective and efficient set-up replacement process so that machine downtime can be reduced. The results of this research show a 52% reduction in set-up time obtained by adding a helper with a time before implementation of 58 minutes to 30 minutes. This research concludes that SMED is effective in reducing machine set-up time and increasing the efficiency of the production process with benefits after implementing the SMED method by adding a helper of Rp. 10,649,336. In this way, implementing the SMED method helps companies increase production set-up replacement times in the rewind section.
