Abstract

This research aims to determine the utilization of information technology in mathematics learning in Class VIII of SMP Negeri 1 Parigi Selatan. This is a case study that describes an actual situation. In collecting data, the researcher used data collection procedures through interviews with informants, who, in this case, were students, as the source of data and information. Qualitative data analysis in this research uses the SWOT analysis method, which systematically identifies various factors to formulate company strategies. This analysis is based on the logic that can maximize strengths and opportunities while minimizing weaknesses and threats. Then, identify the types of errors and conclude. From the strengths perspective, the results indicate that implementing online learning allows learning resources to be easily accessed online. From the perspective of weaknesses, an unstable internet connection affects students' focus on learning and teaching. From the perspective of opportunities, online learning enhances students' self-learning skills and provides new insights into technology and learning. Finally, from the perspective of threats, students' learning motivation decreases.

Abstract

This study aims to determine the effect of the implementation of the REACT strategy on critical thinking skills of SMA Negeri 4 Merauke students. This research was an experimental research design with pretest-posttest control group design, where the research was conducted, namely in SMA Negeri 4 Merauke. Hypothesis testing used homogeneity test. The implementation of the REACT strategy is seen through the acquisition of an average posttest score of 75.58 which was more than the average pretest score of 42.65 in the experimental class, with an increase in the moderate category of 0.5738 and based on a paired T-test sample with a sig value. (2-tailed) 0,000 <0.05 which means that there is a difference between the pretest and posttest, in other words the influence of the application of the use of REACT strategies to the critical thinking skills of SMA Negeri 4 Merauke students. Students' thinking skills are better in which students can solve critical thinking questions given in accordance with predetermined scoring indicators, students write what is known from the problems, students make mathematical models, students use strategies in solving problems and are able to make conclusions from solving the given problem. With the test results obtained by students almost weak on the average criteria of the analysis indicators.

Abstract

Poaceae is a cosmopolitan group of grasses whose diversity is very high in Indonesia due to the diversity of ecosystems and geographical conditions that support the growth of the group. The grasses are easy to grow and resistant to drought and waterlogging. Poaceae are used as food ingredients in Indonesia and natural greening materials that play a role in natural balance. This study aims to inventory and identify plant species of the Poaceae family around Cibiru, Bandung, West Java. The method used in this research is descriptive qualitative method. The research was conducted by exploration, namely exploring along the research location and collecting information on the existence of plant species of the Poaceae family. Plant identification was carried out by matching plant morphological characters using various literature both identification books, journals, and websites. There were five species found including Oryza sativa, Zea mays, Imperata cylindrica, Panicum repens, and Panicum maximum.

Abstract

The Cyperaceae family is a puzzle or "papayungan" family. The Cyperaceae family are weeds because they can grow in different environmental conditions. Many species of this family grow in terrestrial and near-water ecosystems. Plant inventory is an activity that aims to classify a plant species found in an area. This activity is carried out to provide information which is used as a reference for the species of this family that exist in the area, with the aim of knowing the distribution of the species of this family and identifying them. This observation uses the exploration method around the UIN Sunan Gunung Djati Bandung Integrated Laboratory. The Cyperaceae family around the UIN Sunan Gunung Djati Bandung Integrated Laboratory obtained 3 species, namely the species Cyperus rotundus L, Cyperus kyllingia Endl, and Fimbristylis globulosa.

Abstract

Plants are a group of living things that have many cells on earth. Plants have three parts, namely roots, stems and leaves. Babakan Siliwangi has been designated as the lungs of the city and a recreational area in Bandung by Unesco. Having an area of ​​3.8 hectares filled with various animals that complement the ecosystem, Babakan siliwangi has become a Green Open Space (RTH) that can be reached by the people of Bandung City. The Fabaceae family is one of the third largest families which belongs to the members of closed seed plants (Angiosperms) which are easily found in the surrounding environment which have a variety of morphology or stature ranging from herbs, seedlings, shrubs and trees.

Abstract

This study aims to determine the effect of the Thinking Aloud Pair Problem Solving (TAPPS) method on students' mathematical communication abilities. The type of research used is a Quasi-Experimental type (pseudo-experimental) and uses the True Experimental Design research design with the Posttest-Only Controll form. The research was conducted at SMP Ikhlasiyah Palembang with a population of all students of class VII consisting of 2 classes. The sample were taken from all members of all population so that class VII.1 as the experimental class was given treatment, namely the Thinking Aloud Pair Problem Solving (TAPPS) method and class VII.2 as the control class which was not given treatment, namely the conventional method. Research data was collected through tests. Based on the analysis of the test results, it shows that the students' mathematical communication skills in the experimental class are higher than those in the control class. This means that the class that was treated with the TAPPS method affected students' mathematical communication skills. Statistical calculations obtained from the test results yield tcount = 2.944 and ttable = 2.013, so that tcount > ttable which causes H0 to be rejected and H1 to be accepted. Thus, it can be concluded that there is an influence of the Thinking Aloud Pair Problem Solving (TAPPS) method on the mathematical communication abilities of class VII students of SMP Ikhlasiyah Palembang.

Abstract

Indonesia is a country with very high biodiversity both in flora and fauna groups so that Indonesia is nicknamed the "Megabiodiversity" Country. The flora group has high diversity so that it always provides space for continuous study. This can be continued from the provincial, district to sub-district levels. Like one of the provinces in the western part of Indonesia, namely West Java. This province has a wealth of flora that is spread to every corner, including in one of the areas directly adjacent to West Bandung district, known as Jatinangor District. Jatinangor District is one of the areas in Sumedang Regency which is currently in a transitional period towards urban areas. The transition period is certainly a study that needs to be considered because it will impact on the richness of the flora in the region. One group of plants that still survives and is quite often found in Jatinangor District is the Fabaceae or legume family. Fabaceae is a group of plants that ranks third largest (after Orchidaceae and Asteraceae). This plant belongs to the Angiospermae division or plants that have flowers. This family is interpreted as having around 730 genera and 19,400 species with the largest genus being Astragalus (has more than 2000 species), then Acacia (more than 900 species), then Indigofera (more than 700 species), then Crotalaria (600 species), and finally Mimosas (500 species). Fabaceae itself is grouped into 3 subfamilies, namely Mimosoideae, Caesalpinioideae and Papilionoideae. ), and Soybean (Glycine max L). Soybean is the main crop grown with quite a lot of results and uniform size. In addition, there are differences in habitus, leaf shape, and leaf surface between the three types of plants. The variation in the number of samples also indicates the diversity of plant populations in the Fabaceae family at the study site.
