Abstract

Penelitian ini didasari oleh tingkat motivasi belajar siswa yang rendah, sehingga diperlukan adanya perbaikan dalam pembelajaran dengan tujuan untuk menunjang siswa menumbuhkan motivasi belajarnya. Perbaikan pembelajaran dilakukan dengan menerapkan model pembelajaran kooperatif tipe STAD dengan memanfaatkan media teka-teki silang yang dilaksanakan selama tiga kali pertemuan. Penilitian dilakukan pada siswa siswa kelas VII yaitu berjumlah 24 siswa. Rancangan yang digunakan pada penelitian ini yaitu one-shot case study. Teknik yang digunakan dalam pengumpulan data, yakni lembar angket yang digunakan untuk mengetahui tingkatan motivasi belajar serta didukung dengan lembar observasi aktivitas siswa. Berdasarkan temuan penelitian ini, dari hasil angket dketahui motivasi belajar siswa tergolong pada kategori sangat tinggi yaitu sebesar 85%. Hal ini juga didukung oleh hasil observasi aktivitas siswa yang terus meningkat setiap kali pertemuan dilakukan. Kesimpulan penelitian ini adalah model pembelajaran kooperatif tipe STAD menunjukkan pengaruh dalam menumbuhkan motivasi belajar siswa. Kata Kunci: Student Team Achievement Division, Teka-Teki Silang, Motivasi Belajar

Abstract

This literature study aims to determine the actualization of social media networks on academic learning achievements, especially for high school students or Generation Z and efforts to overcome dependence on social media networks. This type of research is qualitative research with a literature study method. The results of literature studies show that Generation Z students spend more time scrolling on social media. Social media that is often used by Generation Z students is Whatsapp, Instagram, Tiktok, Youtube, Facebook and Twitter. Today's Generation Z tends to get bored when they don't use social media because each social media has its own advantages and characteristics that make its users feel at home staring at their cellphone screens all day long. The intensity of social media use of Generation Z students averages more than 3 hours a day. Usually the electronic devices used to access social media include smartphones, laptops and other electronic devices. The positive impact of social media for Gen Z in using social media is to get information related to knowledge, tips and tricks related to learning and will make it easier when doing assignments so it is hoped that it will support each student's achievement. The surefire way for students to become Gen Z to overcome this dependency or addiction to social media, they do by managing or managing their time as well as possible, limiting the use of social networks, increasing outside activities so as to minimize opening social media, by turning off notifications so they can focus more on doing assignments or other things related to school or daily life.

Abstract

As a form of service to the community, Pj. The Governor of West Sulawesi plans to rehabilitate and reconstruct the West Sulawesi Governor's Office Building. As a result of these activities it has negative impacts in the form of reduced air quality, increased noise, increased surface water runoff, health problems for local employees, and piles of domestic waste resulting from construction activities. In order to overcome the negative impacts that occur and develop the positive impacts of management efforts, it is necessary to carry out environmental impact studies that occur during the pre-construction, construction and operation stages. The purpose of this study is to obtain the results of an managing of environmental impact studies and countermeasures in minimizing the impacts that occur during the pre-construction, construction and operation stages. The method used in this research is the observation method and the scoping method to determine the impact and good handling of the environment. This study uses primary data in the form of field surveys, interviews, and is supported by secondary data. The result of this research is to know the initial environmental baseline conditions at the research location and obtain an analysis of the environmental impacts that occur and ways to minimize the impact with good handling in order to create an environmentally friendly construction.

Abstract

The demand for analytical, synthesis and evaluation skills applies to all students, especially in the Tadris/Mathematics Education study program, FTIK IAIN Padangsidimpuan. Students are educated to become prospective mathematics teachers so that high cognitive abilities are needed. The Tadris/Mathematics Education study program has implemented the 2015 KKNI curriculum. For the Discrete Mathematics course, it has not yet developed learning tools using the KKNI curriculum.The purpose of the study was to determine the validity, practicality, and effectiveness of cognitive and affective assessment tools based on the IQF curriculum for the Discrete Mathematics course. The research was carried out in the tadris/Mathematics education study program in semester 4 T.A. 2019/2020 which consists of 2 classes, namely TMM-1 and TMM-2, each of which amounts to 24 people and 33 people. The development model used in this study is a 4-D model, namely defining, designing, developing and disseminating.The results of the research and discussion showed that the cognitive and affective assessment tools based on the KKNI curriculum for the Discrete Mathematics course developed were categorized as very valid at 3.91 or 97.9% for cognitive assessments and 3.71 or 92.85% for affective assessments. Cognitive and affective assessment tools based on the IQF curriculum in the Discrete Mathematics course for students of the tadris/Mathematics education study program developed were categorized as very practical with the final score percentages of 81.56% and 89.93%, respectively. Practicality can be seen from students using cognitive and affective assessment tools.

Abstract

Yogurt adalah produk yang dibuat dari susu yang difermentasi oleh bakteri asam laktat. Bakteri ini memberikan manfaat kesehatan ketika dikonsumsi, seperti memperbaiki mikroflora dalam saluran pencernaan, sehingga dapat digunakan sebagai bentuk makanan fungsional dengan kolaborasi bahan yang kaya antioksidan. Tingginya paparan radikal bebas dari berbagai sumber seperti radiasi, asap rokok, polusi kendaraan dan pabrik, pestisida, obat-obatan, dan lainnya menyebabkan peningkatan risiko kesehatan. Jumlah radikal bebas dan antioksidan yang tidak seimbang dalam tubuh menyebabkan terjadinya stres oksidatif. Salah satu jenis makanan yang berpotensi menangkal radikal bebas dan sangat akrab bagi masyarakat Indonesia adalah beras merah. Beras merah mengandung karbohidrat tinggi yang merupakan sumber antioksidan utama seperti asam fenolik, flavonoid, tokoferol, tokotrienol, proantosianidin, y-oryzanol, asam fitat, antosianin dan termasuk bagian dari serealia. Metode yang digunakan pada uji antioksidan menggunakan metode DPPH, dirancang dengan melihat nilai absorpsi. menggunakan spektrofotometer uv – vis. Hasil yang diperoleh pada penelitian yogurt sari beras merah didapatkan antioksidan kuat pada konsentrasi sari beras merah 30% dengan hasil 72,67 ppm.

Abstract

This test is supposed to break down the utilization of resource put together learning with respect to understudies' applied mathematical comprehension. All 162 students enrolled in class VIII at SMP Negeri 1 Barumun Baru Padang Lawas Rule for the odd semester of the 2023–2024 academic year are included in this exam, which is broken down into eleven classes. An illustration of this test is 26 understudies in class VIII-An and 26 understudies in class VIII-B who were chosen utilizing the purposive test technique. This investigation utilizes a pretest-posttest control bunch plan. Test data is gotten through preliminaries of sensible mathematical comprehension. This exploratory data examination utilized the Mann-Whitney U test. According to research, asset-based learning has a greater impact on students' understanding of numerical calculations than conventional learning does on students' normal numerical understanding. Considering the endlessly results the executives, the finish of this investigation is that resource based learning doesn't influence the expansion in understudies' mathematical comprehension.
