Abstract: Do research on the effectiveness of the addition of chitosan mengetaui shells on the quality of salted mackerel (Rastrelliger sp) to draft a student worksheet that was conducted in April and May 2016. The study was carried out by two phases: the field research and resistant design student worksheet (LKS ). Research experiments were conducted using a completely randomized design (CRD) non factorial, consisting of 5 treatments and 3 replicates in order to obtain 15 units of the experimental design. The observed parameters including moisture content, protein content, fat content and organoleptic value which include appearance, aroma, taste and texture. The results showed that the addition of shrimp shell chitosan significant effect on water content, protein content and fat content in the salted mackerel (Rastrelliger sp). Where to lower the moisture content of up to 9.545%, fat content up to 1,543% and can also increase the protein content of up to 48.905%. While hendonik organoleptic test appearance and taste of the most favored panelist on the addition of 3% chitosan concentration, aroma on chitosan 2% and while the texture preferred chitosan panelist at 4%. Results from the study are used as a design student worksheet (LKS) on the subjects of biology in high school.Key words: Chitosan, Salted Mackerel Fish, Student Worksheet.

Abstract

The research was conducted to determine the difficulty of the material science learning and implementation technology in the teaching learning process of high students in junior schools. The conducted at study was SMP Negeri 28 Pekanbaru, Al-Azhar Syifa Budi Middle School, Metta Maitreya Middle School and Bukit Raya Pekanbaru Middle School. The research methods useng descriptive qualitative which is obtained using Likert scale questionnaire sheets and interviews. Data were analyzed using descriptive analysis toolpak. The results showed that Skeleton System Material included in the category of Fairly Difficult with an of average 25% and the Application of Information, Communication and Technology (ICT) in Schools is still low due to inadequate. Based on the results of the analysis it was concluded that the application of ICT in junior high schools was still very low, so the development of disruptive so, the development of disruptive technology media is needed such as Tech Teacher that it was expected to improve student learning outcomes.
