Abstract

Agricultural wastes are very diverse in type and have low nutrient values, especially in lignin and cellulose, which are difficult to digest. One way of overcoming this problem is by biological treatment using microorganisms, also known as silage. The availability of bio-activators that are both cost-efficient and easy to make further suggests that using local microorganisms may be an effective possible solution. This study focused on processing food crop waste (corn leaves) into silage using local microorganisms as the bio-activators. Research took place in the Agrotechnology Laboratory, University of Jember. The experimental design was completely randomized with four treatments: Treatment 1 (rumen), Treatment 2 (rumen + banana humps), Treatment 3 (rumen + petung bamboo shoots), and Treatment 4 (rumen + gamal leaves). The parameters tested were local microorganism quality (pH, total microbial, and organoleptic) and silage quality (nutrient composition, pH, and organoleptic). After three weeks, the organoleptic local microorganism test results in all treatments showed clear colors, an acidic aroma, small number of fungi, and normal pH (3–5). In terms of silage quality, the resulting local microorganisms could be used as a bio-activator in the silage fermentation process, with the maturity level indicated by a color change (green to brownish green), sweet and acidic aroma, softer tape and texture, and pH of 4–6. The proximate test results of this silage feed showed better nutrient content in the addition of formulations in the manufacture of local microorganisms. Petung bamboo shoots, gamal leaves, and banana humps can increase the nutrient content, mainly the protein. We therefore conclude that local microorganisms from the rumen and local materials can be used as activator materials in making silage from corn leaves with an increase in the value of waste nutrients.

Abstract

The growth and yield of taro (Colocasia esculenta L.) plants are influenced by the planting material. The use of planting material derived from corms is expected to improve the quality and quantity of taro growth and yield. This research aimed to find the best type of planting material and cultivars for taro growth and the potential of taro plants as animal feed. The experiment was carried out in Jember, East Java ( elevation ±89 m asl). The experiment used the randomized completed block design method with two treatment factors, the type of planting material (B) as the first factor (B1: taro corms, B2: taro tiller, B3: taro stolon) and the use of taro cultivars (V) as the second factor (V1: green taro, V2: ketan taro, V3: Sukabumi taro). The treatment was repeated four times. The results showed that there was an interaction between the use of taro planting material and taro cultivar that could influence the tuber weight per plant. The types of planting material had a significant effect on the number of tillers, leaf area, corm weight and diameter, and the planting of several taro cultivars significantly affected all observed variables. The treatment that gave the best results was planting material from taro tuber (B1) and Sukabumi cultivar (V3) with a tuber weight yield of 362.58 g (±14.5 tons/ha). Meanwhile, the Sukabumi cultivar (V3) had the best potential as animal feed. Overall, the stems and leaves of taro had a protein content of 1.19–2.02%, while the corms had 2.82–4.09%.
