Abstract

The export and import industry are now a significant determinant of a nation's economic progress in the age of globalization. A nation's ability to export helps it earn foreign cash that it can utilize to fund development and spur economic expansion. Conversely, import-related activities might assist in satisfying the need for products or services that cannot be effectively provided domestically. Entrepreneurs can increase the competitiveness of local products and the quality of their products through imports and exports, which will enhance both industrial progress and community welfare. To maximize the nation's economic progress, the government and business owners must continue to boost import-export activity. The objective of this study is to evaluate Indonesia's export-import sector's performance using the stepwise modeling approach and the DEA method. One technique to determine which export-import sector activities are effective and ineffective is performance evaluation. These two sectors can support the country's economy in this way and do so with a long-term approach. The research results indicate that efficient DMUs have the smallest presentation (20%) and inefficient DMUs have the largest percentage (80%). The efficient DMU category is C (1). Inefficient DMU categories, namely: SK (0.285), S (0.193), M-US (0.472), and T-J (0.11).

Abstract

CV. Mulya Tempe operates in the food sector, namely leaf tempeh, plastic tempeh, mendoan tempeh and round tempeh. The traditional process of making tempeh leaves takes approximately 80 hours or 3 days until the tempeh product is perfectly cooked. In the molding stage, the soybeans are compacted on a rack by hitting them using wooden tools by two workers. This compaction process was repeated 10 times repeatedly. In addition, at the fermentation stage, additional load is provided by stacking red bricks on top of the compacted soybeans. In the molding or compaction stage, the worker's position is standing and bending. Five Mulya Tempe workers experienced complaints about the neck, elbows, arms, back, waist and calves because the shelves owned by Mulya Tempe did not match the anthropometric measurementsof the workers' bodies. The results of calculating work attitudes using the REBA method get scores of 10 and 11, where the scores fall into the high and very high categories, which requires improvement in work attitudes. Where the tempeh fermentation rack was redesigned by carrying out calculations using anthropometric data, percentiles, data adequacy tests and data uniformity tests.

Abstract

PT Multi Kadera Sejati is a company in the furniture industry that has always prioritised quality in the production of woven chairs. One of the problems that PT. Multi Kadera Sejati is a shortage of raw materials for woven chairs, apart from that, there is no optimal raw material inventory control system and they still use the conversion method, which results in the company experiencing production delays and hampers the delivery process to consumers, which can reduce consumers' confidence in ordering woven chairs from PT. Multi Kadera Sejati. The forecasting methods used in this research are Moving Average and Exponential Smoothing. In Material Requirement Planning (MRP), LFL and FPR lot-sizing techniques are considered to be able to solve this problem. The LFL method was chosen because it has the smallest results and the most optimal results. From the results of MRP calculations with LFL and FRP lot sizing, it was found that lowest cost for LFL was IDR 1,350,000

Abstract

Mr Rizal's MSME is located in Jerukgamping Village, Krian Sub-District, Sidoarjo Regency, East Java, processing the production of rose crackers from raw goods to finished products takes a maximum of 1 day and a maximum of 2 days. This is because there is a drying process that still relies on the sun's heat. The separation process Crackers that are done manually result in the resulting output not being optimal because the process takes quite a long time so it cannot be finished on the same day and must be continued the next morning. With the problems that occur in Mr. Rizal's cracker MSMEs, the researcher provides a solution to speed up the process of separating crackers that are still stuck to each other and only requires 1 worker. The solution used for the problems that exist in Mr. Rızal's rose cracker MSMEs is to carry out anthropometric and percentile calculations. which is used to determine the dimensions of the rose cracker separating machine. The cracker separating machine is designed using dimensions from anthropometry and the 50th percentile of workers so that it can be seen that the height of the machine frame is 103.5 cm, the diameter of the cracker separating tube is 67.25 cm, the height of the cracker exit path is 92.9 cm after it is done. In the experiment there was a comparison of the output of crackers that had been separated. The output before design was 113.5 kg, requiring 200 minutes with an output per minute of 0.6 kg. Meanwhile, the output after design was 150 kg, requiring 60 minutes with an output per minute of 2.5 kg.

Abstract

Performance evaluation is essential for an industry's ability to operate successfully. Efficiency management is becoming crucial and important to enhancing the sustainability of the industry. The industry needs to measure its performance for the following reasons: (i) develop the economy and its operation efficiency in a sustainable way; (ii) supply data for decision-making units (DMUs); and (iii) optimize output using the fewest resources. Performance measurement indicators relate to the performance of the industry itself, such as: added value/cost of production factors, indirect taxes, number of workers, input costs, number of companies, added value/market prices, and production index. The purpose of this research is to measure the performance of large and medium-sized industries (LMIs) in Indonesia. LMIs have a strategic role as the main engine and driver of the economy. Measuring LMI performance is very necessary so that LMI can grow and develop sustainably. Data envelopment analysis (DEA) is a method for measuring performance. DEA is a non-parametric linear programming technique and used to determine comparisons between DMUs with different inputs and outputs. The research results indicate that there are three DMU classification categories, namely: Category 1 (ES = 1), Category 2 (ES = 0.9986-0.9998), and Category 3 (ES = 0.9971-0.9974). The percentages for each category are 50%, 37.5%, and 12.5%.

Abstract

The construction industries are inextricably linked to employment, investment, the quantity of infrastructure building projects, and other economic sectors in Indonesia. They serve as catalysts for the expansion of goods and service production. Apart from having a strategic role in the national economic, construction companies also experience various obstacles to developing their businesses. These obstacles include weakening the IDR exchange rate against the US dollar, regulatory and legal frameworks, labor and skills shortages, economic and financial instability, and environmental and sustainability concerns. In order for the construction industry to survive, develop, and remain competitive in the face of international competition, it is crucial to evaluate its performance constantly. This research aims to evaluate the construction industry's performance in Indonesia. There are 151,183 construction companies included in this study. Hence, these companies will continue to survive, grow, and compete in the face of global competition. The methods applied in this research are an input-oriented DEA envelopment model and a stepwise modeling approach. The research results indicated that 3% of the Indonesian construction industry is made up of efficient DMUs, and the remaining 97% are inefficient DMUs. DMUs are classified according to the distribution of efficiency scores. It is considered that for the classification of inefficient DMU, there exist four ranges, Rs: R1 (ES = 0.16-0.99), R2 (ES = 0.050-0.15), R3 (ES = 0.015-0.049), and R4 (ES = 0.000-0.014). The criteria for each classification, in terms of the level of effectiveness, are as follows: i) R0 Range (ES = 1]): Effective; ii) R1 Range (ES = 0.16-0.99): Relatively Low Ineffectiveness; iii) R2 Range (ES = 0.050-0.15): Moderate Ineffectiveness; iv) R3 Range (ES = 0.015-0.049): Significant Ineffectiveness; and v) R4 Range (ES = 0.000-0.014): Very High Ineffectiveness. The percentage of each classification is as follows: inefficient DMU-R1 0%, inefficient DMU-R2 30%, inefficient DMU-R3 37%, inefficient DMU-R4 30%.
