Abstract

Sayuran terutama sayuran hijau merupakan hasil pertanian yang cukup melimpah di Propinsi Lampung. Sayuran hijau yang terdiri bermacam jenis yaitu bayam, kangkung, kacang panjang, brokoli, sawi dan lain-lain. Dalam hal hasil pertanian berupa sayuran hijau tersebut, masyarakat selalu mengkonsumsi sayuran hijau tersebut untuk kebutuhan sehari-hari sebagai penambah asupan gizi keluarga. Dalam hal mengkonsumsi sayuran ini, secara umum sudah terpola bahwa ada kesulitan untuk memberikan jenis makanan ini pada anak-anak. Kelompok mitra yang terdiri ibu-ibu PKK dan ibu-ibu rumah tangga di Desa Tulung Salak ini tidak pernah punya ide untuk mengolahnya menjadi produk makanan ringan. Untuk mengatasi hal ini Tim pengabdian memberikan materi pelatihan cara membuat sayur krispi. Produk ini berupa sayur krispi yang prosesnya menggunakan alat peniris minyak (spinner). Dengan pengetahuan ini diharapkan selanjutnya para peserta tersebut dapat mempraktekkan langsung pengetahuan yang mereka peroleh. Masyarakat diharapkan dapat membuat sayur krispi sendiri dan dapat dijual untuk usaha sampingan sehingga pendapatan keluarga dapat meningkat. Kegiatan ini juga dapat menjadi alternatif untuk usaha skala rumah tangga.

Abstract

Corncob is abundantly available lignocellulosic biomass resources obtained from crops harvesting and found to be solid waste accumulation on a field. Less corncob is used as a solid fuel for cooking, and a more significant portion is vanished on the field by burning. Promisingly, corncob contains considerable cellulose as one value-added component potentially utilized as biomaterial or biofuel feedstock. However, the presence of lignin in natural lignocellulosic biomass results in recalcitrant structure and hinders cellulose accessibility. This study aimed to investigate microwave-assisted alkaline treatment to retain cellulose in the solid product while removing other impurities in corncob, especially hemicellulose and lignin. Sodium hydroxide was selected as a chemical with some variations in concentration. The chemical treatment was carried out under 400 W microwave power with various residence times and a 1:10 solid to liquor ratio. The cellulose content upgraded from 26.97% to 71.26% while reducing hemicellulose and lignin from 38.49% to 18.15% and 19.28% to 6.4%, respectively, on chemical treatment using 8% sodium hydroxide concentration for 20 minutes residence time. Scanning electron microscope (SEM) and Fourier transform infrared (FTIR) analysis also confirmed the results. The treated corncob also increased its crystallinity from 30.11% to 52.91%.
