Generative Phase

Reproductive traits determine the selection method in plant breeding. The benggala grass of the Hamil cultivar was thought to be apomictic; thus, a study was conducted to determine its reproduction. The research began by studying the morphological characters, continued with observing the generative phase and seed production of the cultivar planted from seeds (generative) and from pols (vegetative). The experiment was conducted in the greenhouse of the Research Institute of Animal Production. The experimental design was a completely randomized design with ten replications, and the treatments were different types of plant materials: seeds and pols. The Hamil cultivar taken from RIAP Collection was planted in pots with a diameter of 40 cm and a height of 30 cm. The results showed that most of the morphological characters of the Hamil cultivar planted from seeds and from pols were not different (P >0.05), so it was presumed that they were apomictic. The difference in morphology was only in the length and width of the flag leaves and the length of the internodes, where the cultivars planted using seeds were higher. The production of seeds, pithy seed weight, and seed germination of cultivars planted using seeds were higher (P <0.05). Further research is needed to determine the apomixis properties based on cytologically Hamil cultivars.   Keywords: apomixis, benggala grass, morphology, plnting material; seed

Bioethanol is one of the energy alternatives which environmentally friendly and sustainable. This research employed Completely Randomized Design with Factorial. There were two treatments, namely without pretreatment and with pretreatment and these were factorized with three levels of urea, namely 0, 1 and 2% with three replications. Finely dry ground banana peel samples were pretreated with NaOH 6% w/v. Simultaneous saccharification and fermentation was performed in 60 mL fermenter.  Sample (4% w/v) was placed in a fermenter and the following ingredients were added: 0.06 g KH2PO4, 0.06 g MgSO4 and citrate buffer with pH 5. Fermenter was enclosed and autoclaved at 121oC for 15 minutes and then cooled down at room temperature. Enzyme cellulose (6% w/v) and inoculum of Saccharomyces cerevisiae (10% v/v) were added into the fermenter. The mixture was incubated at 30oC for 9 days, and every day 3rd, 5th, 7th, and 9th was measured for reducing sugar content, pH and bioethanol content. Bioethanol content of the distillate was measured using picnometer.  Data was analyzed using ANOVA (Analysis of Variance) with Minitab 17 software.

Melon is a type of fruit that has a high water content. High water content causes limited fruit storage, therefore it is necessary to preserve it to maintain the freshness of the melon. One method that can maintain the freshness of the fruit is edible coating. The purpose of this study was to determine the characteristics of organolepic melons given starch-based edible coatings from several types of tubers, namely cassava, canna, and lesser yam. This study used factorial Completely Randomized Design (CRD) with two factors. The first factor is the difference in CMC with a concentration of 1% and 1.5%. The second factor is the difference in glycerol with a concentration of 1% and 3%. The results of the study based on the ANOVA test showed that the type of starch treatment and the concentration between treatments did not have a significant effect on the texture, color, and aftertaste of the melon, but significantly affected the taste and aroma of the melon. So it can be concluded that from all edible coating formulations, panelists preferred the PS I formulation (cassava starch) with 1% CMC concentration and 1% glycerol.Keywords: cassava, canna, edible coating, lesser yam, melons
