Abstract

The escalating buildup of petrochemical based plastic waste has intensified efforts to develop sustainable bioplastics derived from renewable materials. Accordingly, this research investigates how variations in carrageenan content influence the physical and mechanical characteristics of alginate carrageenan composite bioplastics formulated with glycerol as a plasticizer. Alginate was extracted from Sargassum sp. and carrageenan from Kappaphycus alvarezii. Bioplastics were prepared using carrageenan concentrations ranging from 1.5 to 3.5 grams and characterized for tensile strength, elongation, thickness, water resistance, biodegradability, and opacity. The results indicate that carrageenan concentration significantly affects tensile strength, elongation, thickness, biodegradability, and opacity, while water resistance is not significantly influenced. The optimal formulation was obtained at a carrageenan concentration of 1.5 grams, complying with Japanese Industrial Standard and SNI 7188.7:2016. Further studies are recommended to incorporate additional materials to improve water resistance and functional performance of the bioplastics.

Abstract

Packaging plays a strategic role in preserving product quality, shaping consumer perception, and supporting supply chain efficiency, particularly in the ready to drink coffee industry. This study aims to evaluate the performance and importance of Tens Coffee packaging attributes and to identify improvement priorities. This research employs a descriptive quantitative approach using a Likert scale questionnaire distributed to 165 Tens Coffee consumers selected through accidental sampling. Data were analyzed using Importance Performance Analysis (IPA). The results indicate that packaging design and product protection performance meet consumer expectations. However, ease of opening and environmentally friendly materials show high importance but insufficient performance, making them key improvement priorities. These findings suggest that packaging quality is closely related to supply chain efficiency and sustainability. Further research is recommended to explore alternative materials and ergonomic packaging designs to enhance consumer satisfaction and operational efficiency.

Abstract

Food security is an important matter that is of concern to the government, through Bulog the Government controls rice supplies in the country, especially in the city of Semarang where there is a stock out, to overcome this problem a safety stock of 681.93 kg per month is needed as well as the application of three lotting techniques namely lot for lot, EOQ and LUC to determine which lotting technique produces the minimum total inventory cost. Of the three lotting techniques, the lot for lot technique is considered more profitable with a total inventory cost of Rp. 100,620,861 compared to using the EOQ lotting technique with a total inventory cost of Rp. 111,910,165 with a difference of Rp. 11,289,304 greater than the lot for lot lotting technique. The largest total inventory cost by applying LUC lotting is Rp. 128,058,510, with a difference in total inventory costs of Rp. 25,437,684 or 25.3% greater than lot-for-lot lotting, this is because in the simple EOQ model it is assumed that orders arrive all at once and will increase inventory, in reality, orders arrive according to the transport capacity, which is 4 tons. So it can be concluded that if these three lotting techniques are applied, the lot-for-lot technique has the lowest inventory costs.

Abstract

The pipe bending process in the manufacturing industry, particularly for air conditioner (AC) components, often faces quality problems in the form of flattening (ovalization) and wrinkle defects, which can reduce product functionality and strength. Initial data show that the defect rate reached 8.2%, exceeding the company’s target of ≤ 3%. This study aims to reduce these defects by applying the PDCA (Plan–Do–Check–Action) method supported by the Seven Quality Control Tools. Data were collected from 18,000 production units during the January–March period using check sheets and analyzed using histograms, Pareto diagrams, and fishbone diagrams to identify dominant defects and their root causes. Improvement actions included adjusting bending machine parameters, modifying the mandrel design, developing and implementing Work Instructions, adding measuring tools, applying lubrication, and providing operator training. The results show a significant reduction in nonconforming products from 691 units to 37 units, equivalent to 0.21% of total production, with the bending process operating in a stable and statistically controlled condition. Thus, the integration of PDCA and the Seven Quality Control Tools is proven to be effective in improving quality and production efficiency.

Abstract

The palm oil industry is a strategic sector in Indonesia; therefore, the sustainability of Fresh Fruit Bunches (FFB) supply is a crucial factor in maintaining the continuity of Crude Palm Oil (CPO) production. PT Teupin Lada experiences uncertainty in FFB supply due to its dependence on external suppliers without fixed contracts, which leads to raw material downtime and reduced operational efficiency. This study aims to forecast FFB supply and to formulate supply security strategies based on the forecasting results. The Holt–Winters method is employed because it can accommodate trend and seasonal patterns in time series data. The data analyzed consist of historical FFB supply data from January to December 2024. Forecasting accuracy is evaluated using the Mean Absolute Percentage Error (MAPE). The results indicate that FFB supply exhibits a seasonal pattern. The additive Holt–Winters model provides the best performance, with a MAPE value of 6.28%. The forecasting results are then used as a basis for developing supply security strategies, including minimum supply contracts, seasonal incentives, and backup suppliers.
