Abstract

Agricultural waste, including coconut pulp, contains lignocellulose and is a very important, renewable and sustainable industrial raw material. Many of the food, textile, pharmaceutical, paint and resin, agrochemical, oil processing, and other sectors utilize lignocellulosic derivatives. The objectives of this study were to determine the availability of coconut pulp in Padang City-West Sumatra, analyse the lignocellulosic components contained and cell surface morphology, and observe the chemical elements in coconut pulp waste. An exploratory approach was used in this study to achieve these objectives. The results showed that there were 98 coconut milk entrepreneurs spread across traditional markets in Padang City, West Sumatra. Every day the coconut milk squeeze business examined produces ± 1.18 tonnes of coconut pulp. Coconut waste also contains 47.18% cellulose, 10.58% lignin, and 12.10% hemicellulose. Based on the XRD results, the crystal size of coconut pulp obtained from XRD observation is 11.8 nm.

Abstract

Kuantifikasi mikroorganisme menjadi aspek penting untuk menjamin keamanan dan mutu produk pangan. Metode kultur tradisional yang umum digunakan memerlukan waktu lama dan kurang sensitif dalam mendeteksi mikroba viabel. Flow cytometry (FCM) berkembang sebagai teknik analisis mikroba yang cepat, akurat, dan multiparameter dengan kemampuan mendeteksi sel individual berdasarkan karakteristik fisik dan kimia, termasuk viabilitas sel. Studi ini menggunakan pendekatan systematic literature review dengan protokol PRISMA untuk menyintesis hasil penelitian terkini (2020-2025) terkait aplikasi FCM dalam kuantifikasi dan evaluasi viabilitas mikroorganisme pada produk pangan. Dari 450 artikel awal, terpilih 15 artikel yang memenuhi kriteria inklusi. Hasil kajian menunjukkan FCM unggul dibanding kultur tradisional dalam kecepatan, serta tingkat sensitivitasnya pada sel viable but non-culturable (VBNC), dan kemampuan multiparameter, walaupun terdapat variabilitas hasil akibat perbedaan protokol pewarnaan dan kompleksitas produk pangan. Standarisasi prosedur dan validasi antar-laboratorium menjadi kunci keberhasilan implementasi FCM. Aplikasi inovatif seperti integrasi Flow-FISH dan Imaging Flow Cytometry memperluas kemampuan analisis mikroba pangan. Keseluruhan, FCM memberikan potensi besar sebagai metode cepat dan sensitif untuk monitoring mikroba pangan dalam penelitian dan industri.
