Abstract

Tapai is a fermented product that is very popular with the public and has better nutritional value. Using various substrates in producing tapai can be a new alternative in diversifying food processing, one of which is purple sweet potato and Kepok banana, which are a problem in production and occupy the top ranking of agricultural products in Indonesia. Purple sweet potatoes and Kepok bananas have the same essential ingredients as cassava, namely starch. This research was conducted to determine the effect of fermentation time and substrate variations on the physical properties, organoleptic characteristics and acidity levels of cassava tapai, purple sweet potato and Kepok banana. This research was conducted using a completely randomized design experimental research method with a factorial pattern consisting of two factors. The first factor is the substrate factor, and the second is the fermentation time length. The analysis showed that the fermentation time and substrate variations influenced the physical properties, organoleptic characteristics and acidity level of the tapai. Overall, tapai-fermented food was preferred by panelists on the third day of fermentation.

Abstract

This research analyzes students' creativity in making posters using the Project-Based Learning (PjBL) Model. This research uses a case study method. A case study is an empirical investigation that investigates a phenomenon in the context of real life. There are four aspects of creativity. First, creativity is defined as a force within the individual. Second, creativity is managing information and using skills and imagination to do or create something. Third, creativity produces something new or a work of art. Fourth, creativity is a product that is produced, for example, ideas, written works, or products. In this case, creativity shows students' ability to develop ideas about HIV and AIDS in poster form and complete posters on time. Poster-making is an assignment that will foster student creativity. In making posters, students will determine essential things about the material included in the poster. Therefore, using the Project-Based Learning (PjBL) model in the assignment to make posters in class X Science at one of the senior high schools in Serang City can initiate student creativity.

Abstract

Currently, the main challenge in education is to increase student engagement in science learning. Scientific communication skills are critical skills students need. The use of Pictorial Riddle method is a technique, way or effort made in learning to inform scientific facts for students through images, for example presented in the form of posters, pictures on the blackboard, or projections contained in object transparencies. This study aims to explore how the use of Pictorial Riddle learning method can improve students' scientific communication skills and at the same time arouse their interest in science learning. The method used in this research is a case study, using a sample of 57 students of class XI MIPA selected by random sampling technique. The results showed that the Pictorial Riddle learning method has a good effect on students' interest in science learning where students get learning equipped with pictures on the learner worksheet to be analyzed by students. The Pictorial Riddle approach opens space for student creativity, increases active participation, and strengthens understanding of scientific concepts. This can be the basis for innovative learning approaches, namely with a group learning system to develop scientific communication skills and increase student interest in science learning

Abstract

Today's education requires students to manage their learning independently, so that students can set learning goals, set strategies, and even evaluate learning, so that students' understanding of concepts increases. This is related to the learning model used, one of which is guided inquiry. This study aims to determine the influence of guided inquiry on the understanding of the concept of evolution. This study is a quantitative research with a quasi-experimental research design with a non-equivalent pretes-postes control group design The subjects in this study are students of class XII IPA MA Miftahul Ulum Bettet Pamekasan even semester of the 2024/2025 academic year. Class XII Science B is an experimental class with 32 students, while class XII Science C is a control class with 31 students. Sampling was carried out by random sampling technique. The hypothesis test in this study uses the Unpaired T Test. The results showed that there was no influence of guided inquiry on the understanding of the concept of evolution. However, guided inquiry remains a reference for a learning model that can empower a variety of skills for students. Researchers should then consider the factors of student readiness, especially in student habits and learning styles, time factors, and teachers or researchers should have mastered the learning model to be used.

Abstract

This research was motivated by problems identified in a school where the presentation of teaching materials on the human reproductive system did not align with the characteristics of Generation Z students, thereby reducing their interest in learning. To address this issue, relevant and engaging teaching materials are needed. Therefore, a digital magazine format was selected as a potential solution. This study aims to assess the feasibility of a hypercontent digital magazine as teaching material for the human reproductive system, based on material and media aspects. The research employed a Research and Development (R&D) design adapted from Borg and Gall (1983) which is limited to the stages of developing the initial product and conducting expert validation. The research results showed that the product achieved a feasibility rating of 80% (High) for the media aspect and 78% (high) for the material aspect. These findings suggest that the developed hypercontent digital magazine is feasible for use as teaching material on the human reproductive system.

Abstract

Carnivorous plants are plants that have morphological adaptations to prey on and digest small animals as an additional source of nutrition. There are several genera of carnivorous plants, namely Nepenthes, Drosera, Heliamphora, and Pinguicula. Among these genera, they have similar morphological and molecular characteristics and uniqueness. Molecular characterization needs to be carried out to analyze the genetic relationships between carnivorous plant species through the construction of phylogenetic trees. This study aims to obtain information on genetic relationships in several genera of carnivorous plants using an in silico phylogenetic tree based on Internal Transcribed Spacer (ITS) sequences. ITS sequences were collected from NCBI by searching for species names and then aligned using Clustal-W. Subsequently, the construction of the phylogenetic tree was performed using MEGA X with the Maximum Likelihood method and Bootstrap analysis of 1000. The results of the phylogenetic construction of several carnivorous plant genera are divided into two main clades. Clade I is divided into sub-clades: clade IA consists of species from the genera Heliamphora and Drosera with a bootstrap value of 76, while clade IB consists of species from the genus Pinguicula and one species from Nepenthes with a bootstrap value of 56. Clade II consists of species from the genus Nepenthes with a bootstrap value of 52. The results of this phylogenetic construction show the grouping of carnivorous plant species based on genetic similarity.
