Abstract

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. If there was significant (P<0.05) analysis continued with Tukey Pairwise comparison to find the difference among treatments. Results showed that treatment (without pretreatment and with pretreatment of NaOH 6% b/v) combined with levels of urea gave significant effect on reducing sugar and bioethanol content in all observations. Combination of without pretreatment and urea level at 1% and 2% resulted in the highest bioethanol content of 4,91% v/v.Bioethanol is one of the energy alternatives which environmentally friendly and sustainable.

Abstract

Acacia decurrens, originally from Australia, is a woody plant that has become a concern in the erupted areas of Merapi volcano in 2006. The purpose of this study was to quantitatively describe the ecology of Acacia decurrens, and its invasive potential. Vegetation analysis was carried out in four areas of Mount Merapi National Park (TNGM), namely Kalikuning, Kaliadem, Plawangan and Pranajiwa. Ordination using the Non Metric Multidimensional Scaling (NMDS) method and Canonical Correspondence (CCA) and Spearman's bivariate correlation were carried out in data analysis. The results of NMDS analysis (2D stress = 0.14) showed that open areas due to eruption in Kaliadem are now dominated by A. decurrens. The results of the analysis also showed a significant negative correlation (Spearman rho = 0.6) between the abundance of A. decurrens and the level of species diversity in the sampling location. From the results of CCA, A. decurrens in the seedling stage appeared to coexist with other types of ground cover such as Alangium javanicum and Araliaceae. But in the tree phase, this species tended to form pure stands and only occasionally appeared to live side by side with other types of Fabaceae such as Albizia lopantha. Tree-level A. decurrens seemed to prefer sites with lower pH levels while A. decurrens seedling levels were more commonly found in sites with higher pH. Acacia decurrens have the potential to become a weed in TNGM due to its dominant distribution and tendency to decrease the level of species diversity in TNGM.

Abstract

Herbivorous fish have an influence on habitat quality and a major factor in determining coral reef community. This herbivorous fish used as indicator of monitoring refers to reef resilience since of its ability to retain and restore the coral reef condition after disturbance. The presence of herbivores is important in influencing succession of algae, it can reduce and control algae on coral reefs. It’s causes in the availability of space or substrate for corals to recruit. So the research conducted that aims to know the abundance of herbivorous fish in fish apartment as one indicator of monitoring based on endurance. This study had conducted after six months of fish apartment placed in the coastal waters of Tangah Island, Pariaman City, West Sumatra. Then, the observation had done every month for six months in July 2015 - January 2016 at the location of the fish apartment. Observation abundance of herbivorous fish had done by visual census method at fish apartment location. From the results of observations for six months found 10 species of herbivorous fish with total as many as 289 individuals. Zebrasoma scopas is a species with the most individuals than 97 individu. However, to see the effect of herbivorous fish on coral recruitment in fish apartment needs to do further research. Keywords: abundance, herbivorous fish, fish apartment
