Abstract: The aim of this research was to determine the effectiveness 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: Effectiveness of Chitosan, Salted fish Cork, Learning Module.

Abstract : The research was conducted to determine the types of insect pollinators on watermelon (Citrulus lanatus) agricultural land Pekanbaru City in February to June, 2014. Research results are used to teaching materials in the form of learning modules, insektarium media and interactive learning media. This research was carried out by two stage that is the field research stage and stage development of learning resources. Data retrieval technique using total sampling with threere search stations. Station I : located in the Naga Sakti Street, RT 02/RW 02, SimpangBaru Village, Tampan District, Pekanbaru. Station II : located in the Lintas Timur Street Kilometers 18, RT 05/RW 08, Kulim Village, Tenayan Raya District, Pekanbaru. Station III : located in the Ikan Parang Street, RT 03/RW 05, Muara Fajar Village, Rumbai District, Pekanbaru. Biological parameters observed are the type of insect pollinators and physical parameters include temperature, humidityand light intensity. The results showed that there are 13 species of insect pollinators belonging to 6 families and 3orders that the Order Hymenoptera, Order Lepidoptera and Order Diptera. Order Hymenoptera Family Apidae (2 species), Family Anthoporidae (1 species), Family Vespidae (1 species). Order Lepidoptera Famliy Nympalidae (5 species), Family Pieridae (3 species) and Order Diptera Family Syrphidae (1 species). Results of the study can beusedas a learning resourcein the form of learning modules, insectarium media and interactive learning media on biodiversity material class X High School. The average valueof learning resources developed ranged from 3.31 to 3.51with the validity criteria are very valid. The final stageof the research conducted limited testingof learning modules were tested in class X SMA N 8 Pekanbaru the number of students as many as 34 students. Based on the results of this research is that learning resources developed can already be implemented with the validity criteria are very valid.

Abstract: Nongsa is Batam eastern coastal area which is crowded with a variety of industrial activities, transportation and domesti. The waste products of these activities will result in waste of heavy metals Pb and Cd which can pollute the surrounding waters. In order to investigate the quality of coastal waters in the nongsa beach, Batam city, the measurement of heavy metals lead and cadmium in sea water, sediment and Anadara granosa has been done in June 2014 with a survey method. Results of measurement used for the preparation of the student assignment sheet on the concept of water pollution through the stages of analysis, design, and development. The average heavy metal Pb content in sea water is 2,760 ppm, in sediment is 3,870 ppm and in Anadara granosa is 1,460 ppm. While the average heavy metal content of Cd in seawater is 0,032 ppm, in sediments is 0,029 ppm and in Anadara granosa is 0,081 ppm. The results of research can be used as material for the preparation of the student assignment sheet on the concept of water pollution in high school with category Very Good. Meanwhile, to ensure the quality of this product, the testing steps still need to be followed up to the stage of Implementation dan Evaluation. Keywords: heavy metals lead (Pb) and cadmium (Cd), water pollution, Anadara granosa, student assignment sheet

Abstract : The research was conducted to investigate diversity insectpollinators inlong beans (Vygna cylindrica) agricultural land Pekanbaru City in February to June, 2014. Research results are used to development of instructional media in the form of learning modules, student worksheet and interactivemediaofthe results ofthe inventoryof insectpollinators.This research was carried out by two stage that is the field research stage and media development stage. The research was conducted at 3 locations observation using total sampling at each station. Station I: located in the Tenayan Raya District, Seroja Kulim Street. Spacious long beans gardenrange between ± 60x 40 meters. Station II: located in the Rumbai District, Palas Village, Tengku Ibrahim Street Spacious long beans garden ±60x 40meters.Station III : located in the Tampan District, Bina Widya Street, faculty of Agriculture, University of Riau. Spacious longbeans gardenrange between±25x 30 meters the inventory of insect pollinators and environmental physical parameters include temperature, humidity and light intensity. The results showed that there are seven species of insect pollinator sare found in the long beans (Vygna cylindrica) agricultural land Pekanbaru City. Belonging to 6 families and 3 orders that the Order Hymenoptera Family Anthporidae (1 species), Family Apidae (2 species), Family Pesvinae (1 species). Order Diptera Family Syripidae (1 species) and Order Lepidoptera Family Lycanidae (1 species). temperatures ranged between from 25.4 to 31.9 OC, humidity ranged between 69-84% and light intensity ranges from 1673.2 to 3173.5 all physical environmental factors are still within the range of tolerance. Results of the study can be used as a source of learning namely learning modules, student worksheets and interactive media on the concept of interaction patterns of living creatures in Junior High School.
