Abstract

The study was done in August to September 2015 and located in the Kartama Garden (PSN) on Kartama street Marpoyan Damai district area and KOMPPOS – EM garden (PSO) at the University of Riau, Pekanbaru. The purpose of this research is determining metal Cu (copper) in vegetable (mustard, convolvulus and lettuce) and soil, determining the rate of pollution metal Cu, analyzing the use of fertilizer and pesticide synthetic levels of metal Cu in a sample and analyzing the impact of agricultural income activity for farmers. Based on the research, levels of metal Cu in vegetables and soil PSN had passed of quality standard Director General POM RI namely 5,0 mg/kg and categorized polluted metal Cu. While sample vegetable KOMPPOS - EM garden (PSO) is still under environmental quality category and including contaminated. Using fertilizer and pesticide synthetic and continuing to exceed doses constantly affects levels of metal Cu in a sample of vegetables and soil significantly. Economically, PSN and PSO farming is agricultural activity that can give advantages for farmers.

Abstract

Mineral kaolin yang bersal dari Desa Sencalang Kecamatan Kerintang Kabupaten Indra Giri Hilir dapat digunakan sebagai bahan baku pembuatan zeolit karena mengandung SiO2 yang cukup besar yaitu 60,49-83,02 % dan Al2O3 10,63-24,19 %. Zeolit yang dibuat dari peleburan 25 g kaolin dan 35 g NaOH serta penambahan silikat dan aluminat 1:1, mempunyai karakter yang mirip dengan zeolit A. Hasil difraksi sinar-X menunjukkan adanya pola difraksi sudut 2θ berturut turut 7,20: 10,12; 16,13; 21,70; 24,00; 30,79; 34,24; 36,63; 42,63 dan adanya regangan asimetris O-Si-O atau O-Al-O pada bilangan gelombang 1007 dan 1006 cm -1, 715-720 cm-1 regangan simetris O-Si-O atau O-Al-O dari ikatan TO4 tetrahedral. Bilangan gelombang 463 dan 456 cm-1 merupakan vibrasi tekuk TO4 tertahedral sedangkan serapan cincin ganda terlihat tajam pada nilangan gelombang 559 cm-1.

Abstract

Nipa waste from the nira harvest is a fibrous waste that no further processed by the people of Sabak Auh Village, Siak. Even though it has the potential to use as spent-resources product. It has high economic value. The nipa waste content was lignin which can be processed to produce second generation of bioethanol. It is an alternative material to substitute or mixture of petroleum. Bioethanol made in several stages, sample preparation, pretreatment, hydrolysis, fermentation and purification using distillation process. The purpose of this study was to compare the enzymatic hydrolysis process and acid in producing high-purity bioethanol. Hydrolysis process using white rot fungus extract as an enzyme and 1.5 N HCl solution (acid) as a hydrolyzing agent. The fermentation stage was used Saccharomyces cerevisiae yeast to convert glucose into bioethanol. Based on the results of the research, the hydrolysis process using enzymes was better of hydrolysis in producing bioethanol rather than acid. The highest purity was 11.78%, while bioethanol produced from the acid hydrolysis process had a purity level of 3.4%.
