Abstract

Bioethanol is an alternative and potential fuel derived from plants, which has the ability to reduce CO2 emissions. It contains sugar that can be utilized and processed into bioethanol. This study aims to produce bioethanol from pineapple peel (Ananas comosus Merr.) through acidic hydrolysis and fermentation process using Sacharomyces cereviceae. This research was expected to know the optimum condition of S. Cereviceae mass and the time of fermentation on the conversion of pineapple peel into bioethanol towards amount and content of ethanol produced. The hydrolysis was using sulfuric acid (H2SO4), fermented with variations yeast 20, 40 and 60 gram and 2, 4 and 6 days of time variations. The resulting bioethanol was purified using a distillation process, then analyzed by gas chromatography. The results showed that optimum ethanol content was obtain in yeasts 20 and 40 grams and 2 days of fermentation. The resulting ethanol content was 26.3% and 24.6%.

Abstract

Biodiesel is an alternative fuel for diesel engines produced by a transesterification reaction between vegetable oils or animal fats containing triglycerides and alcohol, one of which is methanol. The use of homogeneous base catalysts in the synthesis of biodiesel still poses a problem for the environment because it is difficult to separate, therefore, researchers use variations of heterogeneous base catalysts. The synthesis of biodiesel from used cooking oil was carried out through a transesterification reaction with technical methanol with a catalyst of CaO impregnated Bentonite, K-Bentonite and Bentonite using the reflux method at 65ºC for 2 hours. The ratio of the volume of oil, methanol, and catalyst used is 5:1:1%-w oil. Based on the research that has been done, the yield of each catalyst is 84.85% bentonite, 84.24% K-bentonite and 89.27% ​​K-bentonite-CaO. The characteristics of biodiesel obtained from each of these catalysts such as calorific value and density have met the quality requirements of the Indonesian National Standard (SNI 7182-2012), except for the acid number and kinematic viscosity which still exceed the quality requirements of SNI 7182-2012.

Abstract

Petroleum waste (crude oil) has become one of the sources of pollution in the sea. The pollution caused comes from several factors, oil spills from tankers, deliberate disposal of irresponsible industries. The layer of crude oil on the surface of the air holds back gas exchange from the atmosphere and reduces the solubility of oxygen in the waters so that it interferes with the respiration and photosynthesis processes in phytoplankton which are food producers in the sea. This study aims to characterize the synthesized TiO2 photocatalyst material using two methods, namely Sol-Gel (SG) and Hydrothermal (HD) which will then be used for applications in petroleum waste. To determine effectiveness of TiO2 photocatalyst in reducing crude oil spills on the sea surface based on fatty oil parameter tests. The synthesis of TiO2 was carried out by the solgel method (SG) and the hydrothermal method (HD) at various temperatures of 300 oC, 500 oC, and 700 oC. Characterization of the material formed using the SEM-EDX instrument, showed that in general it is spherical in shape, and is composed of C, O and Ti elements. The maximum effectiveness of SG-300, SG-500, and SG-700 was able to reduce fat oil content by 57.19%, 66.14% and 41.42% while HD-300, HD-500, and HD-700 were able to reduce fatty oil content. maximum of 60.87%. , 56.41% and 45.68% in the 120 minute irradiation time. The results showed that the photodegradation process in petroleum waste treatment using TiO2 material was able to reduce the fat oil content.
