Abstract

Virgin Coconut Oil (VCO) is a processed coconut product with high economic and health value. VCO production is known to be relatively easy, inexpensive, and capable of producing high-quality oil rich in benefits, including as a traditional medicine and natural ingredient for beauty and health. This community service activity aims to provide students of the Biology Education Study Program at Buton Muslim University with an understanding and practical skills regarding the VCO production process as a form of utilization of local natural resources, especially coconuts. The methods used in this activity include lectures or delivery of theoretical material, interactive discussions on the content and benefits of VCO, and direct practice in making virgin coconut oil using the settling method. This method was chosen because it does not require complicated equipment, does not use excessive heating, and is able to maintain the natural quality of the resulting oil. During the implementation, students are invited to observe and follow the entire process, from selecting good coconut raw materials, the grating process, squeezing coconut milk, natural fermentation through settling, to the process of separating oil from sediment and filtering. The results of this activity demonstrated that students not only understood the concept and theory of VCO production but also produced 1,500 ml of virgin coconut oil packaged in five 300 ml bottles. The VCO was then sold to the public for approximately Rp 30,000 per bottle. Through this activity, students not only gained contextual learning experiences but also developed insights into sustainable, locally-based entrepreneurship.

Abstract

This research is motivated by the potential of the waters of South Palabusa, Buton, as an ideal habitat for pearl oyster cultivation. This region has ecological advantages that can support the growth of oysters producing high-value pearls. However, pearl production is still strongly influenced by the application of nucleus implantation techniques and the condition of the aquatic environment. Therefore, this study aims to determine the effect of nucleus implantation on pearl growth and quality and identify environmental factors that play a significant role. The research method used is descriptive quantitative, with subjects being Pteria penguin oysters cultivated by the local community for a period of one month. The main parameters observed included the oyster survival rate, pearl size growth, and the quality of the resulting nacre. The findings provide valuable insight into how nucleus implantation can optimize pearl farming practices. The results showed that oysters implanted with nucleus implants had a survival rate of between 85–90%. Pearl diameter growth reached 1–2 cm per month, with a thicker nacre layer and brighter color than oysters without nuclei. Environmental factors, such as water temperature of 28–30°C, salinity of 30–35 ppt, pH 7.5–8.5, moderate water currents, and high plankton availability, have been shown to support successful cultivation. These environmental factors act as natural enhancers that improve pearl quality and survival rates. The findings of this study imply that the application of appropriate nucleus implantation techniques, accompanied by good environmental management, can increase pearl yield and quality. This not only provides significant economic benefits for cultivators but can also serve as a basis for developing sustainable pearl cultivation strategies in potential Indonesian waters. Thus, sustainable pearl aquaculture can become a promising sector for local communities.
