Abstract

Abstrack: This study aims to determine the effect of the addition of maltodextrin on the composition of instant powder drinks produced by jackfruit seeds (Arthocarpus Heterophyllus Lamk.) As a design of student worksheet (LKPD) for X11 grade biotechnology material. This study used a factorial Completely Randomized Design (RAL) method consisting of 5 treatments and 3 replications, namely protein content using (M0 = 0; M1 = 5%; M2 = 10%; M3 = 15%; M4 = 20%; and M5 = 25%), carbohydrate treatment (M0 = 0; M1 = 5%; M2 = 10%; M3 = 15%; M4 = 20%; and M5 = 25%), levels fat (M0 = 0; M1 = 5%; M2 = 10%; M3 = 15%; M4 = 20%; and M5 = 25%), as well as organoleptic tests (descriptive and hedonic). The results showed that the addition of maltodextrin to the levels of protein, fat, carbohydrate after the results of a variance test (Variant Analysis) showed that the addition of maltodextrin in the composition of instant powder drinks produced by jackfruit seeds had no significant effect. Then the DMRT test was not carried out at the level of 5%. However, the highest and best levels were obtained from protein, carbohydrate, fat, and organoleptic content, namely in the M5 treatment (25%). All scientific facts from the research can be used to design student worksheets (LKPD) on conventional biotechnology materials in class XII of high school using the project based learning (PPA) model. However, before the design of the LKPD is used on a broader scale it is recommended that a feasibility test be carried out on a limited scale.Key Words: jackfruit seeds, maltodextrin, student worksheet (LKPD).

Abstract: This study aims to determine the effect of fermentation time and roasted rice concentration on the quality of Pangas catfish (Pangasius sp.) and produce a booklet design on the conventional biotechnology concept of class XII SMA. This type of research is a quantitative research. The research was conducted in 2 stages. The first stage, namely the experimental stage, is the stage of making Pangas catfish marks. The method used was an experiment with a completely randomized design (CRD) with a 3x3 factorial pattern with 3 replications of the concentration of roasted rice and fermentation time. The fermentation time was 7 days, 14 days, and 21 days and the roasted rice concentration was 40%, 50%, 60%. The research parameters were fat content, protein content and pH. Furthermore, the second stage, namely the design of the booklet, includes the analysis and design stages. The results showed that the duration of fermentation and the concentration of roasted rice affected the quality of Pangas catfish (Pangasius sp.) Marks with the parameters of fat content, protein content and pH where the best quality of catfish (Pangasisus sp) was found in the T3P3 treatment (21 days of fermentation. and roasted rice concentration of 60%) which has a fat content of 1.4661%, a protein content of 10, 7841%, a pH value of 3.3. Based on the potential analysis, the research results can be used as a Booklet Design for Conventional Biotechnology Material for class XII SMA.Key Words: Booklet, fermentation time, roasted rice, Pangasius sp
