Extraction is a crucial process for obtaining active compounds from natural materials, such as medicinal plants, spices, and other biomass. The success of the extraction process is greatly influenced by the method used, as each method has its own mechanism, efficiency, and yield. This study compared seven commonly used extraction methods: maceration, percolation, infusion, soxhletation, reflux, Ultrasound-Assisted Extraction (UAE), and Microwave-Assisted Extraction (MAE). Based on data collected from various scientific journals, it was found that modern methods such as UAE and MAE are capable of producing higher yields than conventional methods. Furthermore, both methods are more efficient in terms of extraction time and solvent usage, making them more environmentally friendly and suitable for industrial-scale applications. However, conventional methods such as maceration and percolation still play an important role, especially in initial research or in laboratories with limited equipment. For example, maceration is easy to perform, does not require high energy, and is suitable for heat-sensitive materials. Other factors that influence extraction results include the type of solvent, temperature, time, and the characteristics of the natural material itself. Therefore, the choice of extraction method must be tailored to the research objectives, the type of compound to be extracted, and the availability of resources and equipment. Combining several methods can also be considered to improve the efficiency and quality of the extraction results. It should be emphasized that extraction yield is influenced not only by the method, but also by the type of material, solvent, temperature, time, and particle size. Therefore, the choice of extraction method must be tailored to the nature of the material, the type of target compound, as well as the objectives and availability of resources. In some cases, a combination of extraction methods can also be used to increase efficiency and obtain optimal results.

This study is motivated by the downstream Teh Walini industry’s reliance on third-party logistics (3PL) services for product distribution, which restricts the company’s control over several key aspects, including logistics costs, delivery speed, routing efficiency, and product handling quality. The primary objective of this research is to analyze and compare distribution costs between outsourced logistics and self-managed delivery, and to evaluate the potential cost efficiency of an independently operated shipping system. A descriptive comparative quantitative method is employed, incorporating movement generation analysis, distribution spread mapping, and Vehicle Operating Cost (VOC) calculations to estimate the cost implications of self-shipping. Data were obtained through company documentation and analyzed using multiple linear regression involving six major distribution points. The results reveal that shipment volume significantly influences movement generation, with Waingapu, Makassar, and Padang identified as the dominant distribution destinations. The cost comparison analysis demonstrates that self-managed delivery is more cost-effective than third-party logistics services, making it a more viable long-term option. These findings suggest that transitioning to a self-delivery system could improve cost control and logistical efficiency for the company. However, this strategy should be implemented gradually, supported by regular updates on operational cost data and proactive management of external factors that could impact distribution performance. The study concludes by recommending broader coverage and the inclusion of additional relevant variables in future research to further validate and enhance decision-making related to distribution strategies. A well-informed shift toward internal logistics could ultimately contribute to greater competitiveness and sustainability in the company’s distribution operations
The spice industry faces significant challenges in maintaining product weight consistency as part of quality assurance and compliance with production standards. A case at PT X revealed that a newly installed filling machine produced deviations from the target weight of 50 grams, with hypothesis testing showing that out of 30 samples, 17 samples fell outside the confidence interval. To mitigate this issue, this study proposes the development of a real-time data-driven Decision Support sistem (DSS) combined with statistical approaches. The methodology includes two-tailed hypothesis testing to detect weight deviations and Failure Mode and Effects Analysis (FMEA) to identify dominant failure causes based on high Risk Priority Numbers (RPN), such as delayed machine calibration, operator error, and worn-out machine components. These findings serve as the foundation for designing the DSS architecture, which consists of sensor input modules, statistical data processing, risk mapping, and an automated corrective recommendation engine. The sistem is designed to enable early detection of deviations, accelerate response time to quality issues, and support data-driven decision-making on the production floor. The study concludes that a structured implementation of DSS can be an effective strategy to improve product weight consistency and enhance operational efficiency in spice manufacturing.
