Abstract

The increasing demand for sustainable agriculture has accelerated the development of biopesticides as environmentally friendly alternatives to synthetic pesticides. However, their application remains constrained by poor stability, low solubility, rapid degradation, and inconsistent field performance. This review aims to evaluate the relationship between bioactive compound production methods and appropriate encapsulation techniques, focusing on fermentation- and extraction-derived biopesticides. A comparative analysis of recent literature was conducted to assess the compatibility of fermentation and extraction processes with coacervation and nanoemulsion encapsulation technologies. The analysis shows that fermentation-derived bioactive compounds, including microbial spores and protein toxins, are best protected through coacervation, which enhances environmental stability and enables controlled release. Conversely, extraction-derived bioactive compounds, such as essential oils, terpenoids, and phenolics, are more effectively formulated using nanoemulsions, improving solubility, dispersion, bioavailability, and biological efficacy while reducing application rates. Matching bioactive production methods with suitable encapsulation strategies significantly enhances formulation stability, active ingredient delivery, and pest control performance. This integrated approach provides a practical framework for developing effective, stable, and commercially viable biopesticides to support sustainable agricultural systems. This review, based on a comparative analysis of recent studies, highlights that fermentation-derived bioactives are more compatible with coacervation systems, whereas extraction-derived bioactives are better suited for nanoemulsion formulations. The findings emphasise that aligning the characteristics of bioactive sources with suitable encapsulation techniques is crucial for improving stability, active ingredient loading, and pest control performance. This integrated approach provides a strategic framework for designing effective, stable, and commercially viable biopesticide formulations that support sustainable agriculture.

Abstract

Desa Tugurejo di Semarang memiliki potensi rumput laut yang melimpah dan belum dimanfaatkan oleh masyarakat secara optimal, maka diperlukan langkah strategis dalam pengembangan pemanfaatannya. Ketersediaan tambak di wilayah ini mencapai sekitar 535 hektar, dengan mayoritas digunakan untuk budidaya ikan dan udang. Selain itu, terdapat tambak yang dimanfaatkan oleh petani untuk budidaya rumput laut dengan hasil produksi rata-rata 2-3 ton per hektar dalam satu masa panen. Masalah pada Sea Farm yaitu penurunan kualitas dan stabilitas hasil produksi rumput laut terutama saat musim hujan dengan kandungan kadar air pada rumput laut hingga 30-40%, petani rumput laut terkendala dalam pengelolaan usaha seperti manajemen usaha, produksi, dan pemasaran. Solusi yang dapat di aplikasikan yaitu advanced technology in seaweed drying berbasis IoT, serta penerapan pengelolaan usaha dengan melakukan manajemen usaha, produksi, dan pemasaran. Tujuan pengabdian ini adalah meningkatkan kuantitas hasil rumput laut dan penggunaan teknologi alat pengering otomatis sehingga meningkatkan kesejahteraan petani serta masyarakat Kelurahan Tugurejo pada umumnya. Metode yang akan dilakukan meliputi koordinasi tim dengan mitra PKM, konstruksi alat advanced technology in seaweed drying berbasis IoT, Praktik penggunaan alat drying, Sosialisasi dan pendampingan penggunaan alat kepada mitra, kemudian yang terakhir yaitu evaluasi pelaksanaan dan keberlanjutan program di lapangan.
