Abstract

New Zealand White Rabbit (Lepus negricollis) is a good growth by requiring good nutrition for growth. Combination of natural food (Papaya Leaf-Turmeric-Cassava Leaf-Bekatul) as an alternative for rabbit feed. This study aims (1) to determine the effect of a combination of natural food (Papaya-Turmeric-Cassava Leaf-Bekatul) on the growth of New Zealand White (NZW) rabbits (Lepus negricollis), (2) to determine the best combination for New Zealand White (NZW)rabbit (Lepus negricollis)growth, (3) To find out whether the results of this study can be used as a biology learning of source in growth and development material in the form of Student Worksheets(SW). The research was carried out for 30 days, rabbits were given feed at 06:00 AM and 07:00 PM. The results showed that there was an effect of eating a combination of natural foods on the growth of rabbits. The best growth in weight and length was in the P3 treatment with a combination of papaya leaves, turmeric, cassava leaves, rice bran as much as 35% with a long growth yield of 6.75 cm and a weight of 390gr. The results of this study can be used as a learning resource for high school biology class XII in the form of Student Worksheets (SW) for growth material and living things.

Abstract

Pepper (Piper nigrum L.) is a spice plant that has high economic value and has good prospects. The use of the right method will also optimize the growth of pepper seeds, one of the stages of pepper seedling is one of which is covering. The purpose of this study was to determine the effect of the length of coverage on the viability of pepper (Piper nigrum L.). This type of research was an experiment using a completely randomized block design (CRD) and using 3 treatments, one control and 5 replications. The research was conducted for 35 days from 23 March to 3 May 2020. The parameters observed were number of live cuttings, shoot height and root length. The data obtained were analyzed using the One Way Anava Test. The results showed that the length of covering had an effect on the viability of pepper cuttings (Piper nigrum L.).The results of this study can be used as a source of learning biology in the form of LKPD (Student Worksheet).

Abstract

This study aimed to determine the effect of guided discovery learning on the critical thinking skills of students in class VIII Science in SMP N 2 Raman Utara. This type of research is experimental with a design using Posttest Only Control, Researchers use instruments in the form of essay test items (descriptions) that are used by researchers to measure students’ abilities after carrying out the learning process using a guided Discovery Learning. Researchers used 2 groups with research design, namely the control group using the Direct Learning model with the question and answer method and the experimental group using guided Discovery Learning with the group discussion method. The research data is tested for hypotheses with the similarity test of two averages. The test results with the normality test show = 9,93 > X2daf = 11,07 α = 0.05, then, in the similarity test two t-count average > t-daf is 17,9 < 2,01 (= 5%). So there is an influence of guided Discovery Learning on students' critical thinking skills at SMP N 2 Raman Utara.

Abstract

The aims of this study are 1) knowing the effect of MOL concentration of conch mas on cayenne pepper production and 2) knowing the concentration of MOL from conch mas is most optimal for cayenne pepper production. The study used a complete randomized design (RAL) and data analysis using a single-track ANAVA against cayenne pepper production. The study used 4 treatments (4% concentration, 7%, 10%, and 13%), 1 control, and 5 repeats. The results of the study showed that there is an effect of giving MOL and mol concentration of 7% conch mas is the most optimal for the production of cayenne pepper (Capsicum frustescens L.) with a yield of 2.5 kg of 1181 pieces higher than the three concentrate treatments tested. MOL consisting of a mixture of conch mas containing macronutrient protein 12.2 mg, Phosfor (P) 60 mg, potassium (K) 17 mg, as well as various other nutrients such as C, Mn, Cu, and Zn greatly affect the number of fruits/trees.

Abstract

The aims of this research are; to determine the effect of the concentration of red dragon fruit peel extract on the results of the yield and organoleptic tests, to determine the best concentration on the results of the yield and organoleptic tests and for the preparation of teaching materials (LKPD) on biotechnology materials. The organoleptic test aims to determine the level of preference for VCO based on 3 parameters namely: 1) Color, 2) Taste, 3) Texture This research is an experimental research with a RAL research design with 5 treatments (P1; 15%, P2; 20%, P3; 25%, P4; 30%, P5; 35%) and 6 replications. The data analysis technique in this research uses ANOVA 1. Based on the analysis results; The concentration of dragon fruit peel extract influences the yield results and organoleptic tests. The P1 concentration produced the highest yield and the best organoleptic tests on 3 parameters (color, taste, texture). The source of teaching materials (LKPD) for biotechnology material has been validated by design experts and material experts, with a design aspect percentage of 95.27% and a material aspect percentage of 98.43% with the category very valid and suitable for use.
