The aims to determine the effect of chitosan concentration and smoking time on the quality of smoked catfish (Pangasius sp.) and produce Student Worksheet design. This research was divided into two step, there is experimental step and the Student Worksheet design. At the experimental step, used a factorial Completely Randomized Design (CRD). Factor I is the concentration of chitosan, and factor II is duration of smoking time. This study consisted of 12 treatments with 3 replications so that there were 36 experimental units. Parameters observed were protein content, fat content, water content and organoleptic on appearance, scent, taste and texture. The results showed that the effect of chitosan concentration and smoking time had an effect on treated with 3% chitosan and 3 days of smoking showed the best results, with the total protein content was 35.89%, fat content was 29.72% and water content was 15.27%. Meanwhile, the organoleptic test results of smoked catfish on the aspects of appearance, scent, taste and texture, the best treatment was also found in smoked catfish with 3% chitosan treatment and 3 days of smoking time. The results can be used as a student worksheet design on Food Additives material for class XI high school.

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 Parasitology is the study of living organisms as parasites in humans and their relationship as causes of disease, disorders and death. In the course of parasitology, students are faced with the problem of some diseases by parasites that are widely circulated in society, so students are required to have a broader knowledge of a disease caused by parasitic organisms. Thus, the ability of literacy attitude is needed. Literacy of science is an important ability to support the ability to explain and apply science in life. However, in fact the ability of science literacy has not been trained properly. For that done a research in improving the attitude of science literacy in students. This study aims to analyze the improvement of science literacy attitude aspect in biology education students through the application of problem based learning model (PBL) in the course of parasitology. This study is a quasi experiment with non-equivalent pretest research design and posttest control group desaign. The sample of this study consists of 36 students who take the course of parasitology. Technique of data collecting is done by using scale scale of science literacy attitude which arranged by likert scale. Data analysis used SPSS 22 program. The result showed that the N-gain class of experiment and control class were in medium category (0,56 and 0,44). It can be concluded that the learning model of Problem Based Learning can improve the science literacy aspect in biology education students who take the course of parasitology. Keywords: Parasitology, Literacy and Learning Model of PBL

The effect of Naphthalene Acetic Acid (NAA) and Benzyl Adenine (BA) of concentration of leaf eksplan Citrus sinensis L. by in vitro was studied at tissue culture laboratory of Balai Benih Induk Pekanbaru, The experiment was conducted using Completely Randomized Design (RAL) with three replicates. The treatment consist of A (without NAA and BA), B (0,1 ppm NAA and 0,1 ppm BA), C (1 ppm NAA and 0,1 ppm BA), D (10 ppm NA and 0,1 ppm BA), E (0,1 ppm NAA and 1 ppm BA). F (1 ppm NAA and 1 ppm BA). G (10 ppm NAA and 1 ppm BA), H (0,1 ppm NAA and 10 ppm BA), I (1 ppm NAA and 10 ppm BA) and J (10 ppm NAA and 10 ppm BA),The results of this experiment showed that respond growth of good leaf eksplan. NAA and BA at concentration 0,1; 1 and 10 ppm can yield forming o f root and callus can’t forming of buds. Callus initiation and root quickest of concentration 10 ppm NAA and 0,1 ; 1; 10 BA ppm that is 10,00 and 14,66. Amount root o f concentration 1 ppm NAA and 10 ppm BA is 29,66 and wet weight of callus high at gave of concentration 10 ppm NA and 10 ppm BA is 0,25 gr.
