ABSTRACT The research was to determine utilization of organic waste with starter fluid cow rumen raw material for biogas production in March and May 2015. Results of the study are used to enrich the teaching materials in the form of biology modules vocational school Agriculture on the concept of waste management. This research was carried out by two phases: experimentation and enrichment modules. Research conducted experiments using completely randomized design (CRD) non factorial, which consists of 4 treatments and 3 replicates in order to obtain 12 experimental design. If there is a real test there will be a further test Duncans Multiple Range Test (DMRT) at 5%. The parameters observed biogas volume, the color of the flame, calor and power. Enrichment module is performed on the stage of analysis and design. The results showed that the use of organic waste with starter fluid cow rumen could potentially produce methane gas as a source of biogas. Treatment A (25% substrate: 75% starter) are best produce biogas with a biogas volume of 11.57 L, color blue flames, calorific value 5670 J and power 132.98 watts for 28 days of fermentation. The results could be used as an module enrichment for biological subjects Agriculture vocational school on the concept of waste management. Keywords: Module, Organic Waste, Fluid Cow Rumen, Biogas.

ABSTRACT The aim of this study is develop of student worksheets based on constructivism on sirculation system for biology subject of class XI Senior High School. This development consisted of six student worksheets. This study was conducted in Biology Education Program University of Riau and Senior High School Babussalam Pekanbaru on September to December 2015. Validation sheets and student responses sheets were used as data collection instruments. Validation sheets were filled by the internal and external vaidators. Student responses sheet were filled by student class XI Senior High Scholl Babussalam Pekanbaru. The development of student worksheets use 4D pendekatan that consists of define, design, develop and disseminate but only until develop. Collected datas were analyzed by descriptive statistics. The result of this worksheets development showed that the student worksheets were very valid with score 3.38-3.64. Student responses to the worksheet were very good with score 3.33-3.72. Based on validation result and student responses, this students worksheets based on contruktivism approach could be implemented with filed test.

ABSTRACT The aims of this research to determine the quality of tempeh milk powder by time fermentation and designing Student Worksheet relevant to a material Food Biotechnology Food Fermentation sub material. This study consisted of two phases. The first phase, were the making of tempeh milk powder using the experimental method with completely randomized design (CRD), which consists of 5 treatments and 3 replications. Parameters measured were moisture content, protein content, fat content, pH and organoleptic test. The results obtained were analyzed by ANOVA and a further test DMRT at 5% level. The second phase were the development of Student Worksheet from the results of the first phase. This research used ADDIE development model (Analysis, Design, Development, Implementation and Evaluation) are simplified into phases Analysis, Design and Development. Data of Student Worksheet development obtained from the validation sheet which validated by 3 validators with 5 validity criterias were analyzed descriptively. Results showed that the time of fermentation influence on moisture content, protein content, fat content, pH and organoleptic test. Fermentation time 12 hours is a long time to produce the best fermented tempeh milk powder quality. Which results in moisture content of 0.78%, 2.61% protein content, fat content 2.00% and 5.01 pH levels. As for organoleptic texture, color, aroma and flavor contained in the fermentation 36 hours. Results of the study can be used as Student Worksheet in the sub materials Food Fermentation on the material Food Biotechnology with a mean value of 3.32 validity valid category. Keywords : Student Worksheet, Food Biotechnology, Tempeh Milk Powder, Time Fermentation.

ABSTRACT The aim of this research was to determine the effectiveness addition of chitosan shells on the shelf life of salted fish cork (Ophiocephalus striatus) in February and May 2015. The results are used to develop the concept of learning modules on the subjects of food biotechnology Biotechnology. This research was carried out by two phases: the field of research and development phase of learning modules. Research conducted experiments using completely randomized design (CRD) non factorial, which consists of 4 treatments and 3 replicates in order to obtain 12 experimental design. If there is a real test there will be a further test DMRT. The parameters observed water content, protein content, fat content, organoleptic color, aroma and texture. The results showed that administration of chitosan have a significant effect on water content, protein content and fat content in cork salted fish (Ophiocephalus striatus). Chitosan concentration of 2% is the best concentration. Where to lower the water content of 23.11%, amounting to 0.182% fat content can also increase the protein content of 60.95%. While the color and aroma of salted fish most preferred cork panelist in the treatment of 1.5% while the texture of the panelists preferred the treatment of 1%. Results of the study can be used as a learning module that is in the food preservative materials on subjects Biotechnology. Keywords: Chitosan, Salted fish Cork, Learning Module.
