Abstract

Piperine, the primary bioactive compound in Piper retrofractum Vahl or Javanese long pepper, offers various pharmacological benefits, including anti-inflammatory, anticancer properties, and the enhancement of drug bioavailability. The need for efficient piperine extraction has grown as ongoing research emphasizes its potential as a key component in the pharmaceutical and nutraceutical industries. This study aims to evaluate the impact of ethanol concentration and maceration time on the yield of piperine from the plant Piper retrofractum Vahl, commonly known as Javanese long pepper. Piperine is the primary active compound responsible for the pharmacological properties and the pungent taste characteristic of the plant. An ethanol-based extraction method was chosen due to its perceived environmental friendliness and cost-effectiveness. In this study, extraction was carried out using various ethanol concentrations (75%, 80%, 85%, 90%, and 95%) and different maceration durations (14, 16, 18, 20 and 22 hours). The results showed that increasing ethanol concentration and extending maceration time significantly enhanced the piperine yield, with the optimal piperine concentration obtained using 95% ethanol and a maceration time of 20 hours. The extraction product from this operating condition yielded about 35.02%, with a piperine content of 3.245%.

Abstract

Lobster plays a pivotal role in the fisheries industry, and the potential development of this business needs to be thoroughly understood to support regional economic growth, particularly in Sebubus Village, West Kalimantan. This research aims to study prospects and simulations of the techno-economic aspects of lobster cultivation businesses in West Kalimantan. The research methodology involves collecting primary and secondary data through field surveys, interviews with business stakeholders, and analysis of relevant economic data. The data were obtained from lobster business locations in Sebubus Village and secondary data from recent scientific articles. The data used encompass aspects such as production costs, selling prices, and other factors affecting the sustainability of the business. Based on the results of techno-economic simulations with fixed variables of harvest composition (A 30%, B 30%, C 40%), critical factors for lobster cultivation businesses were identified, including a minimum seedling capacity of 14.87 kg, a minimum survival rate of 67.65%, a maximum decline in lobster selling prices of 20.42%. In contrast, an increase in feed prices did not significantly affect the lobster industry. This research is expected to contribute significantly to understanding the lobster business economy in Sebubus Village and surrounding areas. Its practical implications involve efforts to enhance production efficiency, reduce risks, and create a conducive business environment for lobster industry stakeholders.
