Abstract

This study aims to describe the implementation of technological pedagogical and content knowledge (TPACK) in learning in senior high schools. The research approach used is qualitative with descriptive type. Data was collected by conducting in-depth interviews and data analysis using analysis using the Miles and Huberman model with the stages of data reduction, data presentation, and drawing conclusions. The results of this study indicate that the implementation of TPACK in SMA has not been implemented optimally. This is because there are several obstacles encountered such as the unavailability of facilities that support optimally in several schools. The facilities in question include internet networks and learning tools in the form of computers and LCDs. In addition, the increase in the ability of teachers to implement TPACK-based learning is still uneven. This is a challenge in applying TPACK to learning optimally. The alternative chosen in learning is to use conventional learning by utilizing the facilities available at school.

Abstract

This study has been conducted to isolate and identify cellulolytic bacteria from the digestive tract of turkeys (Meleagris gallopavo) as probiotic candidates for poultry. This study has obtained 4 bacteria that have the potential as probiotic candidates through the morphological identification stage, the ability to produce cellulase enzymes and resistance to acidic pH conditions. The test found that RDL code bacteria bacteria have the highest ability to produce enzyme cellulase characterized by the formation of a clearing zone with a diameter of 11 mm, the second highest PVB2 code bacteria with a clearing zone diameter of 7 mm, DB1 4 mm, and RSL 2 mm and the results of bacterial viability tests isolated at low pH (2.0) showed the highest viability after incubating for 4 hours. RDL viability is 65%, RSL 48%, DB1 50%, and PVb2 29%. So based on the tests that have been carried out, it is estimated that the 4 bacteria are candidates for Lactobacillus sp. worthy to be used as a probiotic for poultry

Abstract

The reason for this think about was to look at the impact of Project-based STEAM acquisition on college inventive considering and basic considering aptitudes. The ponder utilized a quasi-experimental plan using a nonequivalent pretest-posttest control gather plan. The populace for ponder were all understudies in Sunan Ampel State Islamic University, Surabaya whereas the test utilized included one department of Biology for the test course and one department of Engineering, utilized as the control lesson. The purpose of this study is to provide an overview in the form of a description of the implementation of STEAM-based acquisition for children aged 5-6 years at Al-Azhar Syifa Budi Surakarta Kindergarten. The information collected was at that point analyzed utilizing the ANOVA test. The pjBL-based STEAM acquisition had a critical impact on understudies’ imaginative considering abilities (P 0.000 < 0.005; Fcount = 25.551). The pjBL-Based STEAM acquisition had a critical impact on understudies’ basic considering aptitudes (P 0.003<0.05, Fcount=9,401). So, PjBL-Based STEAM acquire can be utilized as elective acquire to enable 21st-century abilities.

Abstract

This study aims to determine the storage of biomass in the mangrove ecosystem of Jakarta Bay compared to Ambon Bay. This research used descriptive quantitative method. Sampling technique using the Point Center Quarter Method (PCQM) which was measured around the chest height of mangrove trees (DBH). Data analysis was performed using an allometric equation where each mangrove plant has a specific gravity. The results of this study indicated that the composition of mangrove species in Ambon Bay consists of 6 mangrove species, namely: Bruguiera cylindrica (L.) Bl, Rhizophora apiculata Bl, Sonneratia alba Smith, Aegiceras corniculatum (L.) Blanco, Avicennia officinalis L, Ceriops tagal. In the ecosystem, Rhizophora apiculata Bl and Sonneratia alba Smith had higher biomass values compared to the other four species. Meanwhile, in Jakarta Bay, the composition of mangrove plants is dominated by Sonneratia alba Smith. The subsurface biomass in the Jakarta Bay and Ambon region is lower than the aboveground biomass.

Abstract

The Metal Coating course in Unimed's Mechanical Engineering Education Department only uses learning media in the form of printed textbooks and there is no interactive media that can improve student competence in the affective and psychomotor domains. To increase student competency in metal plating courses, learning media in the form of interactive multimedia that has been validated for its quality is needed. This study aims to validate learning media in the form of interactive multimedia using the ADDIE development model. As for the three acquisitions of interactive multimedia validity, namely analysis of metal plating course requirements, determining learning objectives and designing interactive multimedia, as well as developing interactive multimedia involving several material experts, learning design experts, and learning media experts, as activity validators. Data collection techniques for interactive multimedia validation are carried out by distributing questionnaires. The validation assessment criteria used a Likert scale which was analyzed descriptively. The results showed that the validity of the material expert was 89.7% in the very good category, the learning design expert was 91.58% in the very good category and the learning media expert was 88.3% in the very good category. from these data it can be concluded that the use of interactive multimedia in the teaching and learning process in the metal plating course developed is very valid to be implemented in the teaching and learning process

Abstract

The learning process has not emphasized developing problem-solving skills since students memorize concepts, thus, the skills are not optimally trained. This study aimed to compare students' problem-solving skills between groups of students using the Problem-based Learning (PBL) model with the E-STEM-based student worksheet and the PBL-only model on environmental pollution at one of the Islamic Senior High Schools in Banda Aceh, Indonesia. This study employed a quantitative method with an experimental research approach using the pretest-posttest control group design. The population was all grade 10 students at the school studied, and the sample was 84 students using a total sampling technique. The instrument was ten long answer questions to measure problem-solving skills. Analysis of students' problem-solving skills data was done by t-test at a significant level of 0.05. The results indicated differences in students' problem-solving skills after experiencing the PBL model applied combined with an E-STEM-based student worksheet on environmental pollution.
