Abstract

Plastic is one of the materials most widely used by humans. The more plastic that is used, the more plastic waste is released into environment and will polute water areas in various sizes, both macroplastics and microplastics. Microplastic are classified as plastic particles whose diameter is less than 5 millimeters. One type of microplastic that has an adverse impact on the life of aquatic organisms is polyvinyl chloride (PVC). The aim of this research was to determine the effect of PVC microplastic exposure on the survival rate and growth performance of tilapia, Oreochromis niloticus. This study was conducted in a completely randomized design (CRD) consisting of four treatments with three replications. The treatments were as follows: MP0 = No addition of microplastics (control); MP1 = Addition of 5 mg/L microplastics; MP2 = Addition of 15 mg/L microplastics; MP3 = Addition of 20 mg/L microplastics. The results showed that exposure to polyvinyl chloride microplastics on the survival rate and growth performance of tilapia through water made a real difference to Survival Rate (SR), absolute weight growth, absolute length growth, Specific Growth Rate (SGR), Feed Convension Ratio (FCR) and the abundance of polyvinyl chloride microplastics in fish gut.Keywords:MicroplasticPolyvinyl chlorideTilapiaSurvival rateGrowth performance

Abstract

Indonesia ranks third globally in Pinctada maxima pearl quality, yet small-scale farmers in Sugian Village, East Lombok face critical challenges with spat survival rates of only 1-5%, far below the economically viable minimum of 25-30%. Limited knowledge and skills in providing quality live feed constitute the primary constraint. This community service program aimed to enhance community capacity in communal live feed cultivation and establish sustainable production systems through technology transfer. The program employed a community-based learning approach with 18 participants, involving socialization, participatory facility development, technical training in Chaetoceros sp. cultivation, and comparative trials between outdoor and laboratory culture systems over four months. The outdoor culture system achieved Chaetoceros sp. density of 3.28 × 10⁶ cells/ml on day-3, only 9.8% lower than laboratory conditions (3.60 × 10⁶ cells/ml). Training significantly improved participants' knowledge from 16.7% (pre-test) to 83.3% (post-test), with 88.9% demonstrating independent culture capability and 46% mastering cell density calculation techniques using haemocytometer. The communal live feed cultivation model proved viable and sustainable, providing knowledge foundation for improving spat survival rates through consistent quality feed provision. This replicable model offers a practical framework for empowering small-scale pearl oyster farmers, potentially increasing spat survival rates from 1-5% toward the target of 25-30% through adoption of proven immersion feeding techniques.
