Abstract

The current research has primary objective that is to assess the effect of implementing the Inquiry-Based Learning Model in enhancing students' academic performance in the field of Science at SMA Smart Indonesia. The Inquiry-Based Learning Model promotes proactive student engagement in exploring, gathering, and interpreting information through independent investigation. The study utilized a quasi-experimental design encompassing pre-test and post-test phases. The participants were selected randomly via a simple random sampling technique. The acquired data underwent analysis using the N-Gain method (T-test). The outcomes revealed a noticeable improvement in the academic performance of students in the experimental group who were exposed to the Inquiry-Based Learning Model, particularly in the context of the human respiratory system. Furthermore, the null hypothesis (H0) was invalidated, as was proven by the 2-tailed Significance value of 0.000 that was smaller than 0.05. This discovery underscores the substantial positive impact of applying the Inquiry-Based Learning Model on enhancing students' academic achievements when compared to conventional teaching methods employed in the control group. In conclusion, this study highlights the significant potential of integrating the Inquiry-Based Learning Model into the Natural Science curriculum at the secondary school level, which could potentially elevate the standard of education and overall student learning accomplishments.

Abstract

The Kampar River is one of the rivers in the upper reaches that has caused pollution due to local communities such as excessive activity and gravel and sand mining. The purpose of this study was to determine the density of phytoplankton in the Kampar River in Koto Kampar Hulu Subdistrict, Kampar Regency. Purposive sampling was used to determine observation stations, which took into account habitat types and biological parameters observed such as species composition, abundance, and diversity index. The findings revealed that five classes of algae were discovered in Kampar Chlorophyceae, Cyanophyceae, Zygnematophyceae, Bacillariophyceae, and Xanthophyceae. The abundance of phytoplankton in the Kampar River's waters is classified as moderate fertility, ranging from 2,419.96 cells/liter to 3,629.96 cells/liter.

Abstract

Remaja mengalami perubahan dalam fisik seperti perkembangan seks sekunder dan organ reproduksi. Remaja mulai tertarik dengan seksualitasnya dan memiliki perhatian terhadap lawan jenis. Perubahan tersebut tidak hanya terjadi pada remaja pada umumnya, tetapi remaja disabilitas juga mengalami hal yang serupa. Remaja disabilitas membutuhkan pengetahuan terkait dengan pengalaman seksualnya dan kesehatan reproduksi, tapi kenyataannya pengetahuan remaja disabilitas masih sangat kurang sehingga tak jarang mereka mendapatkan kekerasan seksual. Di SLB Melati guru melaporkan bahwa siswa-siswi mereka belum paham cara melindungi diri dari pelecehan seksual dan kesehatan reproduksi. Lebih lanjut, jumlah siswa-siswi di SLB Melati yang rata-rata sudah memasuki usia remaja menjadi perhatian bagi sekolah untuk pemberian edukasi terkait seksualitas mereka. Maka dari itu, penting untuk memberikan psikoedukasi kepada remaja disabilitas di SLB Melati untuk meningkatkan kesadaran kesehatan reproduksi. Hasil kegiatan menunjukkan bahwa terdapat peningkatan pengetahuan peserta sebesar 46,5% setelah kegiatan dilakukan.

Abstract

Understanding is one of the bases for developing learning models, with an emphasis on indicators of learning understanding. One alternative when learning can enable increased understanding of concepts by using the CTL learning model. The purpose of this study was to determine the effect of CTL on increasing the ability to understand biology students' concepts. The type of research used was a quasi-experimental design in the form of a nonequivalent control group design. The quasi-experimental group has a control group, but cannot fully function to control external variables that affect the implementation of the experimental group. The research design uses the pretest method before the lesson starts, then is given treatment using the CTL learning model, and ends with a posttest to measure differences in the level of students' conceptual understanding abilities at each meeting. The form of this research is quantitative. The results showed that there was an effect of using the Contextual Teaching and Learning (CTL) learning model on students' understanding of concepts with a pretest control class score of 65 and a posttest of 75. Meanwhile, the pretest and posttest experimental class scores were 80

Abstract

This research aims to identify types of aeroplankton as air quality parameters in the Pekanbaru area. Aeroplankton samples were collected using the Purposive Sampling method where samples were taken 1x24 hours for 20 days in 2 different sub-districts, namely Sukajadi District and Tenayan Raya District. Identification and counting of aeroplankton is carried out in the laboratory. The results showed that the abundance of aeroplankton in Sukajadi subdistrict was higher than in Tenayan Raya subdistrict. In both sub-districts, the abundance of aeroplankton is dominated by the phytoplankton and zooplankton groups. Where aeroplankton can be the basis for air quality parameters in the two sub-districts.
