Abstract

Male inflorescence residue of the oil palm rich in fibre and contains cellulose content and has the potential to synthesize Carboxymethyl Cellulose (CMC). Male inflorescence is considered necessary removed in the early stages of the oil palm cultivation process to develop stem size, string and robust root systems. This activity generates plentiful of oil palm male inflorescence residues in the plantation. The aim of this research is to synthesis and characterize CMC fabricated from oil palm male inflorescence (OPMI-CMC) waste for use as an ice cream stabilizer, using a variety of treatments, which are commercial CMC 0.2%, OPMI-CMC 0.1%, 0.2%, and 0.3%. The results showed that CMC can be produced from organic waste of male flowers of oil palm plants. The water content, pH, purity, and degree of substitution meet the standard. The optimal concentration of OPMI-CMC for ice cream stabilizer is 0.3% based on melting time and overrun value. The FTIR analysis shows that the main functional group of the OPMI-CMC is highly comparable. Therefore, to possibly be employed as an alternative to organic CMC for food stabilizers, other standards must be fulfilled, and further research is required.

Abstract

Alang-alang (Imperata cylindrica) and Saliara (Lantana camara) are dominant weeds in several crop cultivation areas, so that when control is carried out, waste from both weeds will be produced in large quantities. Management of waste from both weeds can be done by utilizing it as a more environmentally friendly bioherbicide. Bioherbicide application is carried out pre-growth so that control is carried out faster and attacks newly germinated weed seeds, so that weeds do not appear on the surface and weed control activities will be more efficient. Alang-alang is the most dangerous weed and is highly avoided because it contains allelochemical compounds that can inhibit the growth of the main plant, this compound is found in all parts of the weed but is found most in the roots. Saliara also has a high content of allelochemical compounds which causes a distinctive aroma from its leaves. The allelochemical content of both weeds can be used as active ingredients in bioherbicides and is effective in controlling other weed species. Several studies have reported that bioherbicide extracts from both weeds are effective in inhibiting weed growth so that they can be used as an alternative to herbicides. However, bioherbicide application must be carried out with the right technique and concentration so as not to interfere with and inhibit the growth of the main plant.
