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.

Abstract: This research was conducted to determine the diversity of insects in lowland rice farming in Bungaraya Village, Siak Regency as a biology pocket book design for class X SMA. The study was carried out in lowland rice farming in Bungaraya Village for insect sampling. Meanwhile, insect identification was carried out at the Laboratory of the Biology Education Study Program, Department of Mathematics and Natural Sciences, FKIP, Riau University. This research was conducted in October - November 2021. This research consisted of two stages, namely identification and analysis of insect diversity, the second stage was the design of a pocket book. Parameters measured in this study were insect species composition, insect diversity index, air temperature, humidity, and light intensity. The results showed that the diversity of insects at rice planting age had different diversity. Insect diversity at stations I, II, and III was moderate. The diversity index value at 30 days of rice planting age was 1.87, 60 days of rice planting age was 1.58, and 90 days of rice planting age was 1.55. The types of insects found in lowland rice Oryza sativa Kampung Bungaraya consisted of 5 orders, namely Odonata, Orthoptera, Coleoptera, Hemiptera, and Lepidoptera. The results of the study can be used as an alternative source of learning in the form of a pocket book for learning biology in high school.Key Words: Insect, Arthropoda, Pocket Book, Bungaraya

Abstract: This research was conducted in May - June 2022 with the aim of knowing the bivalve community structure in the mangrove area of Tanah Merah Village for the design of handouts as biology teaching materials for class X. This research was carried out in the mangrove area of Tanah Merah Village for bivalve sampling while for identification of bivalves carried out at the Laboratory of the Biology Education Study Program, PMIPA FKIP Department, Riau University. The parameters measured in this study were species composition, abundance, diversity, dominance, temperature, salinity, pH, sediment type, and organic matter. The research method used was a survey method, where sampling samples used the squared transect method. At the study site, 3 (three) observation stations were determined, three transects were drawn at each station, where each transect was placed in a 5m x 5m square plot. Based on the research results, 3 species of bivalves were found, namely Anadara granosa Phapia textile, and Geloma erosa. Bivalve abundance values obtained between stations ranged from 0.57-0.89 ind/m2. The index value of species diversity ranges from 0.68-1.51, which is classified as moderate and the dominance index value ranges from 0.37-0.71. The results of the study can be used as an alternative teaching material in the form of handouts in class X high school biology learning.Key Word : Bivalve, Handout, Structure Community
