separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.

Sweet corn is a high-value horticultural crop with steadily increasing demand for both fresh consumption and use as a raw material in the food industry. This study aims to evaluate the effectiveness of NPK 16-16-16 fertilizer on the growth and yield of sweet corn. The research was conducted at Sindangbarang Experimental Field, Faculty of Agriculture, IPB University from July to October 2025. This experiment used a Randomized Complete Block Design (RCBD) with a single factor, namely the dose of fertilizer application. Treatments were using fertilizer dosages of 0, 50, 0,75, 1,00, and 1,50 NPK 16-16-16, with a control treatment for comparison. During the vegetative phase, sweet corn exhibited similar growth responses across all fertilization levels relative to the control. However, all fertilizer doses significantly improved stover weight, cob weight with and without husk, cob length, cob diameter, yield per plot, and overall productivity compared to the control. The application of NPK 16-16-16 fertilizer at the recommended (1.0) rate achieved the highest relative agronomic effectiveness (103.11%), corresponding to a 1.03-fold yield increase over the control and outperforming the comparison treatment. Application of NPK 16-16-16 at the 1.0 recommended dose is suggested as the most efficient fertilization strategy for sweet corn production, as it maximizes yield and productivity without unnecessary increases in fertilizer input.

This study aims to analyze the workload of sewing operators within a single production line and to equalize the workload using the line balancing method at PT. Pan Brothers. The garment industry requires high production efficiency; therefore, balanced workload distribution among operators is necessary to ensure optimal production processes. This research used an observational approach with data collection through direct observation of the sewing process, literature study, and documentation of production data. The research population consisted of 36 operators on the observed production line, analyzed through time study activities. The analyzed data included cycle time, takt time, and work processes at each workstation. The results showed that several processes had cycle times exceeding the takt time, specifically in processes number 2, 5, 6, 12, 17, 23, and 26, which caused bottlenecks and workload imbalance among operators. The calculation results indicated that the actual process time reached 520 seconds per product, while the ideal time based on takt time was 287 seconds per product, resulting in a time difference of 233 seconds or about 44% longer than the standard time. The implementation of the line balancing method was carried out by redistributing work elements from processes with high workloads to processes with remaining work capacity. The improvement results showed that the workload among operators became more balanced, the production process became more efficient, and the potential for bottlenecks could be minimized, enabling the company to achieve its production targets.

Vegetables are an important horticultural commodity in fulfilling community nutritional needs; however, their consumption level in Indonesia remains relatively low, necessitating efforts to increase production. Spinach (Amaranthus sp.) is a promising vegetable due to its short growth cycle, ease of cultivation, and high nutritional value. Limited agricultural land, particularly in urban areas, poses a major constraint to conventional cultivation, thereby encouraging the adoption of alternative technologies such as hydroponics. The hydroponic system, especially the Nutrient Film Technique (NFT), offers efficient use of land and water while enabling better control of plant growth. This review aims to identify hydroponic cultivation techniques for spinach in greenhouse conditions and to analyze factors influencing its success, including nutrient concentration, growing media, pH, temperature, and light intensity. The findings indicate that optimal nutrient concentration ranges from 410–900 ppm, supported by proper environmental and pH management to enhance vegetative growth. The implementation of the NFT system improves production efficiency, resulting in more uniform, cleaner, and higher-quality yields. Nevertheless, challenges remain, including nutrient management, environmental fluctuations, and pest and disease risks. Therefore, proper and sustainable system management is essential to ensure successful hydroponic spinach cultivation.

This study aims to analyze the impact of inflation on the profitability of Micro, Small, and Medium Enterprises (MSMEs) operating in traditional markets. Inflation influences key business aspects, including rising production costs, declining consumer purchasing power, and instability in input prices, all of which can disrupt business performance. The research employed a quantitative approach using survey data collected from MSME actors to assess these effects. The findings reveal that inflation has a significant negative impact on MSME profitability, particularly through the reduction of profit margins. This occurs as businesses face higher raw material costs while simultaneously experiencing a decline in sales volume due to weakened consumer demand. As a result, many MSMEs struggle to maintain financial stability and sustain their operations under inflationary pressure. These findings highlight the need for adaptive strategies among MSMEs, such as cost efficiency and pricing adjustments. Additionally, the study offers important policy implications for the government to support MSMEs through targeted interventions, including price stabilization measures and financial assistance programs, in order to maintain business resilience and economic sustainability.

This study analyzes the concept of al-Kasb in the view of Muhammad ibn al-Hasan al-Shaybani and assesses the relationship between this concept and contemporary work ethics. With the changes in the modern economic system, which emphasize efficiency, objective rationality, and the achievement of optimal results, various ethical conflicts in the professional and business world have become more apparent. The methodology applied in this study is a literature review with a descriptive-analytic approach, through the analysis of classical and contemporary texts to explore the theological, ethical, and social aspects contained in the concept of al-Kasb, and then conceptually compare it with the characteristics of modern work ethics. The findings of this study show that al-Kasb is not only understood as an economic activity aimed at accumulating wealth, but also as a normative guide that integrates the goals of worship, ethical responsibility, and social obligations in the production process. Work activities are viewed as an individual responsibility that supports the practice of worship and as a collective responsibility to maintain social-economic welfare and harmony. Therefore, al-Kasb provides an integrative ethical foundation that has the potential to enrich and strengthen current work ethics by emphasizing values of integrity, justice, and social responsibility in the economic aspects of life.

Abstract: One of the most common harmful bacteria, particularly in hospitals, is Pseudomonasaeruginosa, which is also the most frequent cause of wound infections. Because it leads to antibioticresistance and persistent infections, one of the most significant virulence factors it produces isbiofilm. The goal of the current study is to prevent P. aeruginosa isolates from wound patients fromforming biofilms by using plantaricin, which is a peptide with broad-spectrum antibiotic generated byLactobacillus plantarum. In order to produce plantaricin, so that Lactobacillus plantarum isolates from rawbuffalo milk were screened. The plantaricin was then purified using ammonium salts and a gelfiltration column, with a final 40% recovery. The isolates of P. aeruginosa with more production tobiofilm from wound infections were tested for the inhibitory impact of pure plantaricin. The resultsshowed that the plantaricin reduced the development of biofilms in a dose-dependent manner, with alarger percentage of biofilm inhibition reaching 46–68% at 150 µg/ml.
