Abstract

This investigation aimed to analyze the effects of different diets and determine the optimal feed on the growth performance of guppy Poecilia reticulata (Peters, 1859). In the present study, juvenile guppies were procured from commercial fish breeders, Kolathur, Chennai, and fed with four experimental diets, namely Diet I (Control-Pellet feed), Diet II (Formulated feed), Diet III (Dry Tubifex), and Diet IV (Live feed Brachionus plicatilis) to examine the effects on growth and survival rates. In the experiment, 12 glass circular tanks with a volume of 10 L were used, and ten juveniles having an average body length and weight of 0.8 cm and 0.01 g were randomly introduced into each aquarium (80 cm×30 cm×35 cm) in triplicates. During the experimental study, the fish were fed two times a day ad libitum for 90 days. The various growth parameters and proximate composition of the diets were calculated by following standard methods. The findings showed significant differences (p<0.05) in the fish's various growth parameters fed with different diets. The fish fed with Diet IV 52% crude protein performed better than those provided with lower levels. The increase in growth parameters could be attributed to increased levels of dietary crude protein. However, the diet does not have any significant impact on fish survival rates. Thus, it is concluded that the Live Feed B. plicatilis with 52% crude protein is suitable for theoptimum growth of Poecilia reticulata under the current experimental set-up and recommended for feeding juvenile guppies.

Abstract

One of the world of education components that specifically aims to develop students' creativity is the Youth Scientific group (KIR). Based on the case studies, information was obtained that KIR participants generally still have difficulty generating ideas. Some of the factors that caused KIR participants' difficulty in creating ideas were lack of knowledge and the absence of a guide to guide them in making ideas. The purpose of this study was to develop a technical guidebook for making ideas for KIR students. Products are developed through development research in a sequence of steps: Define, design, and develop. This study provides the results that the product being developed has the following characteristics: 1) consists of 2 parts, namely the formation of new cognitive schemes and the formation of product idea designs, 2) The section on the formation of the New Cognitive Schema is designed based on the cognitive load theory, 3)The product idea design section is designed based on the Creative Process Learning theory. The product developed has a score with a very decent category but needs to be given significant improvements in the aspect of indicators and the addition of entrepreneurship material and SWOT analysis.

Abstract

ABSTRACT Woody plant produce small to large seeds which can affect germination process. Cotyledons as an important food source for early growth of seedlings. The position, function, and type of cotyledons when seeds germinate varies. This research aimed to determine cotyledons characters of woody plant seedlings collection in Bogor Botanic Gardens. The position, function and type of cotyledons were observed for 65 species of seedlings.This research used an observative method and was analyzed descriptively.The position of cotyledons when the seeds germinate are epigeal (above the ground) and hypogeal (remain in the soil). The epigeal cotyledons type found in 44 species that is higher than hypogeal cotyledons type (21 species). The function of cotyledons for seedlings is to reserve food or photosynthesis. Species with cotyledon reserve type were more than foliar cotyledons type (43 species and 22 species, respectively). The proportion of seedling types CER (cryptocotylar-epigeal-reservoir), CHR (cryptocotylar-hypogeal-reservoir), PEF (phanerocotylar-epigeal-foliaceous), PER (phanerocotylar-epigeal-reservoir), PHR (phanerocotylar-hypogeal-reservoir) were 3.08%, 16.92%, 33,85%, 29,23%, 16,92%, respectively.

Abstract

The research background is that it can develop biological assessment based on science process skills because science process skills are important for logical thinking to train students' thinking skills. From the results of the initial needs analysis of class X questions, science process skills are still low, the teacher has not fully developed the science process skills-based assessment because it still uses questions from biology books. This study aims to determine the characteristics and feasibility of assessment based on science process skills developed in biology class X semester 2. This research is development research. Development is carried out using a procedural model by adapting Mcintire's research and development model, with 4 stages of test development including defining competencies, test participants and test objectives, developing test plans, compiling test items, writing administrative instructions. This research stage is limited because it only wants to know the characteristics and feasibility of the assessment. The research instrument used an interview sheet, a questionnaire sheet, and an observation sheet. Expert validation was carried out by 6 expert validators: (1) material experts; (2) linguists; and (3) evaluation experts; The data analysis technique uses qualitative descriptive that refers to the formula adapted by Sugiyono (2018) with a scale of 4. The results of this study are in the form of a biological assessment based on science process skills in the form of multiple-choice questions in which there is biology material for class X semester 2. Biological assessment characteristics are based on science process skills, namely using indicators consisting of observing, grouping, interpreting, predicting, asking questions, hypothesizing, planning experiments, applying concepts, and communicating. The feasibility of a biological assessment based on science process skills based on expert validators, the results are valid to very valid so that the biological assessment based on science process skills developed is feasible to be used to measure the science process skills of class X students.

Abstract

Education is a need for every child to have insight and hope for goals because basics education is helpful until the end of life. The existence of life-long learning indicators is very relevant to be applied by students in learning biology. These indicators include complex thinking, information processing, effective communication, collaboration/cooperation, and thinking habits. This study aims to determine the urgency of providing life-long learning for students in biology learning. The research method uses qualitative methods, the research instrument used in this study is a questionnaire. The results showed that the student's response was in the high category with a percentage of 60%, which means that students already understand the concept of life-long learning but have not applied it in their daily lives. 60.9% of students responded that life-long learning had not been implemented in biology learning at school and agreed if it was applied in biology learning. Therefore, the provision of life-long learning for students in biology learning is considered very important to apply.
