Abstract

Higher order thinking skills are needed in 21st century learning. This study aims to determine the profile of higher order thinking skills at the level of creating biology subjects for high school students in Banten Province and a comparison of students' creative abilities in each district/city in Banten Province. The research method used was a phenomenological approach and school sampling with random sampling technique was used in 8 cities or districts of Banten Province in March-October 2020. Data were collected using a questionnaire technique. The data collection instrument is a questionnaire. The data analysis technique uses the Miles & Huberman model. Based on the results of the study, it was shown that the higher-order thinking ability of students at the creative level in Banten Province was 6.8 which was included in the very poor category. The learning process that has not taken the HOTS approach and is not used to providing students with high-level thinking questions makes students find it difficult to solve the problems they face.

Abstract

Banten is one of the provinces in Indonesia with the quality of education that has not been said to be good. One of the causes of the low quality of education is the low thinking ability of students. This research aimed to determine the HOTS (High Order Thinking Skill) ability analytical skill of biology material for SMA/MA students in Banten Province by used description question. The research method used is descriptive qualitative. The sampling technique used in this study was random sampling. The sample used was 320 students in Banten Province. The instrument used was a description of the analytical skills, interview sheets and questionnaire sheets. The research was conducted from March to November 2020. Based on the results of the research, the average analytical ability of students in Banten Province was in the less category with a score of 22,19.

Abstract

Inquiry skills are important basic skills that science teachers must possess. Inquiry skills underlie the standard implementation of the science learning process. This descriptive study aims to obtain an overview of the mastery of inquiry skills possessed by prospective biology teacher students in plant anatomy practicum. The research method used in this research is descriptive method. The research subjects in this study were prospective biology teacher students (n=42). The instruments used in this research are inquiry skills tests and interviews. The results showed that the average student inquiry skills was 43.36. This result is still below the indicator of completeness in mastering skills, which is 75. The acquisition of an inquiry skills score on the indicators of identifying problems (29.76), designing experiments and carrying out experiments (50.79), analyzing and interpreting data (54.76), constructing explanations (42.86), generate arguments from a number of evidences (43.33) and communicate information (38.69). The conclusion of this study is that the verification practicum learning experience that has been experienced by students has not been able to develop student inquiry skills optimally, so it is necessary to design lecture programs both in class and in laboratory to develop students' inquiry skills.

Abstract

Slamet Reservoir is an artificial reservoir located in the lowlands of urban areas. The existence of this reservoir with a stagnant water habitat type has great potential to become a natural habitat for various types of dragonflies, especially the Libellulidae family. This study aims to inventory and identify the types of dragonflies in the family Libellulidae in the Slamet Reservoir. In this study, the Visual Encounter Survey (VES) method was modified by using the Belt Transect method. This method is an observation by following a predetermined circular line. Sampling was carried out by catching adult dragonflies using insect nets and then preserving them using 50% acetone. After preservation, the body part of the dragonfly was measured using a caliper. The results showed that in the Slamet Reservoir there were 12 species of dragonflies from the Libellulidae family with a total of 131 individuals. The species with the highest relative abundance value in the Slamet reservoir is Brachythemis contaminata with a value of 51.15%. While the species with the lowest relative abundance values were Acisoma panorpoides, Diplacodes trivialis and Pantala flavescens with a value of 0.76%.

Abstract

Production of bioethanol from jackfruit peel waste using Saccharomyces cerevisiae with crude enzyme ratio treatment of Trichoderma reesei and Aspergillus niger. Bioethanol is an alternative energy that is starting to be needed, along with the depletion of petroleum reserves. Bioethanol can be obtained from various wastes, one of which is jackfruit skin with the help of enzymes from T. reesei and A. niger and fermentation using S. cerevisiae. The purpose of this study was to determine the sugar content and the highest ethanol content of jackfruit peel waste using S. cerevisiae with the ratio treatment of crude enzymes T. reesei and A. niger. This research is experimental research. The experimental design used RAL with the independent variables being the ratio of crude enzymes T. reesei and A. niger, namely (1:0), (0:1), (1:1), (1:2), (2:1), (1:3), (3:1) and the dependent variable was the sugar and ethanol content of fermented jackfruit peel using S. cerevisiae. The measurement of sugar content using the DNS method, while the measurement of ethanol content using an alcoholmeter. Data analysis used one-way ANOVA (SPSS version 16). Based on the results of the study, the highest sugar content was in the ratio of crude enzymes T. reesei and A. niger after crude treatment 1:3 (14.21%) and after fermentation 1:2 (14.73%). The highest ethanol content was in the ratio of crude enzymes T. reesei and A. niger 1:1 (1,32%).
