Abstract

One of the factors for improving the quality of education in schools is teaching materials. Based on the results of observations at SMAN 1 Sitiung students have not used e-modules but use electronic teaching materials in the form of pdf files downloaded from the internet and only in the form of writing and a few pictures. Based on the questionnaire results, it is known that students have difficulty understanding the concept of the respiratory system material. This causes low student learning outcomes as evidenced by the daily test scores that are still below the minimum completeness criteria. So, it takes teaching materials that can help in visualizing the subject matter. This type of research is Plomp model development research which consists of three stages: the initial investigation stage, the development or prototyping stage, and the assessment stage. The research subjects were class XI students at SMAN 1 Sitiung for the 2022-2023 academic year. Validation results by the validator on e-module-based Science Technology Engineering and Mathematics (STEM) show an average grade 88.05% (very valid). Practical results by Biology teachers showed an average score of 87.50% (very practical) and 88.28% students (very practical). Effectiveness test data has effectiveness with very effective criteria in terms of cognitive competency assessment with an average of 83.59, affective with an average of 84.24, and psychomotor with an average of 81.08

The purpose of this research is to produce an android based ebook in Animal Ecology courses that is valid, practical and effective. This research is research and development using the Plomp model. The results of the validation assessment by the validator of the android-based e-book in the Animal Ecology course showed an average value of 82.33% (very valid). The results of the practicality assessment by lecturers of the Animal Ecology course showed an average value of 81.5% (very practical) and student assessment results obtained an average value of 91.64% (very practical). The results of the effectiveness test of Android-based e-books show that Android-based e-books are very effective. Thus, it can be concluded that the developed Android-based e-book is very valid, very practical, and very effective.

Abstract

The educational process aims to make students master science. Education is also very important in shaping the personality and behavior of students. The purpose of this study was to analyze the implementation of the active learning learning process in MTs Negeri throughout Tanah Datar Regency. This type of research is descriptive qualitative,the data analysis used is by scoring, presenting data and determining the frequency of implementing active learning for teachers and students of MTs Negeri in Tanah Datar District. The results of the analysis of the implementation of active learning with a percentage of 30% in the frequent category, 33.33% in the sometimes category and 6.67% in the never category. Where the average implementation of the active learning learning process for MTs Negeri teachers in Tanah Datar Regency is 87.96% which is included in the frequent category and means having good criteria. As for the results of the implementation of each variable such as the use of learning models by 82.5%, lesson planning by 93.3%, implementation of learning 87.2% implementation of evaluation 88.6% and obstacles in learning 69, 3% and the negative impact and positive impact of learning by 81.3%. Implementation of active learning by students gets the value of each variable such as learning planning with a percentage of 73.9% after that the implementation of learning is 83.2% learning evaluation is 90% obstacles in learning 53.9% % and positive and negative impacts of learning by 62%.

Abstract

Technological developments have a big influence on the learning process. Various positive influences can be seen with technological developments, one of which is electronic learning media. The existence of electronic-based media has a positive impact on learning because of the various advantages it has. In reality in the field, there are still many biology teachers who do not use electronic learning media in the learning process. Learning media that does not utilize technology tends not to attract students' attention due to its monotonous nature. Based on these reasons, researchers developed electronic learning media in the form of e-modules based on Google sites. E-module is able to visualize and clarify various abstract concepts. E-modules can help teachers to facilitate students in learning and support the learning process. The development of a Google Sites-based e-module was created using the Plomp model which consists of 3 stages, namely the initial investigation stage (preliminary research), the development or prototyping phase (development or prototyping phase), and the assessment phase (assessment phase). The results of the e-module development show that the overall validation value of the Google Sites-based e-module is 86.40% (very valid) from experts. Furthermore, the practicality assessment given by the teacher towards the Google Sites-based e-module showed an average result of 96.25% (very practical).

Abstract

The development of Student Worksheets (LKPD) based on a scientific approach to material on the human circulation system and digestive system is based on the teaching materials used at SMA Negeri 16 Padang in the form of Student Worksheets (LKPD). The LKPD is not complete in terms of components or in terms of LKPD elements. The LKPD used only takes the form of sheets containing questions, and does not use an approach that contains activities or learning steps so that it cannot train students' science process skills. This research aims to produce LKPD based on a scientific approach to material on the human circulation system and digestive system that is valid, practical and effective to improve students' science process skills. This research is development research using the Plomp model which consists of three stages, namely preliminary research phase, development or prototyping phase and assessment phase.   The results of the LKPD validity test by the validator obtained a value of 84.67% with very valid criteria.   The results of the LKPD practicality test obtained a score of 90.74% by teachers and 88.30% by students with very practical criteria. The results of the T-test showed differences in values between the experimental and control classes with a significance of 0.000 each in the circulatory system and digestive system material. It can be concluded that LKPD based on a scientific approach is very valid, very practical and effective in improving science process skills.

Abstract

Terminalia catappa L. (ketapang) is a multipurpose tree species that is widely found in tropical coastal areas and has significant ecological and economic value. This study aimed to describe the nursery technique of Terminalia catappa L. at the UPTD Certification and Forest Plant Propagation Center (BSPTH), West Sumatera Forestry Service. The method used was direct observation and active participation in all nursery activities, supported by literature review. The results showed that the nursery of T. catappa was carried out generatively using natural seedlings collected from Pantai Tiram, Padang Pariaman Regency. The process consisted of three main stages: (1) collection of seedlings with a height of 15–30 cm with healthy stems and leaves; (2) weaning of seedlings into polybags (12 × 17 cm) with growing medium of soil, compost, and rice husk; and (3) routine maintenance including watering, fertilizing, weeding, and pest control until seedlings were ready for distribution. The success of T. catappa propagation was strongly determined by seedling quality, careful extraction to maintain root integrity, growing medium composition, shade intensity management, and consistency of maintenance activities. This study provides valuable information for forest rehabilitation programs, particularly in coastal replanting efforts in West Sumatera.
