The purpose of this study was to determine the effect of learning the Teams Games Tournament type assisted by crossword puzzles (TTS) media on the interests and learning outcomes of Class XI MIA SMA Terpadu Hati Tersuci Maria Halilulik Academic Year 2021/2022. This research was conducted in a control class, colloidal system material was taught using a conventional model, while in the experimental class using the Teams Games Tournament type learning model assisted by crossword puzzles (TTS) for 4 meetings. For students' interest in learning, both classes were given questionnaires before and after learning activities. The results of the research hypothesis test showed that there were significant differences in interest and learning outcomes between students who were taught using the Teams Games Tournament type learning model in the form of crossword puzzles (TTS) and students who were taught using conventional learning models. The t-test results obtained sig.2-tailed value <5% significant level, namely 0.02<0.05 so that H0 was rejected and H1 was accepted.Keywords: Teams Games Tournament, Crossword Puzzles, Interest in Learning, Learning Outcomes

Kegiatan pengabdian kepada masyarakat ini dilaksanakan secara daring bagi guru-guru Kimia se-NTT pada tahun 2022. Dasar pelaksanaannya adalah kebutuhan guru-guru Kimia akan suatu panduan dalam pembelajaran dengan memanfaatkan teknologi yang inovatif guna meningkatkan minat belajar siswa seiring dengan perkembangan era digital. Kegiatan ini bertujuan untuk meningkatkan kemampuan guru dalam memanfaatkan teknologi guna mendesain pembelajaran yang menarik dan inovatif. Di era digital saat ini, guru-guru tidak hanya dituntut untuk meningkatkan kemampuan mengajar berdasarkan pengetahuan materi yang dimiliki, namun juga dituntut untuk dapat menerapkan pembelajaran yang interaktif dan inovatif guna mendorong dan memotivasi siswa dalam belajar dan berpikir kritis. Media pembelajaran yang digunakan dalam kegiatan ini yaitu pembuatan instrumen soal menggunakan quizizz dan wordwall. Biasanya guru-guru di sekolah memberikan soal ujian kepada siswa dalam bentuk manual, sehingga siswa merasa bosan untuk menjawab pertanyaan dalam soal tersebut. Pembuatan soal menggunakan quizizz dan wordwall akan memotivasi siswa dalam mengerjakan soal karena disajikan lebih menarik dan interaktif. Layar akan menampilkan skor siswa secara realtime, sehingga siswa dapat melihat urutan skor mereka dengan antusias. Media ini juga cukup mudah untuk dikembangkan bagi guru sehingga memudahkan guru untuk menerapkannya dalam pembelajaran. Guru juga akan lebih mudah dan cepat dalam menyusun nilai ujian siswa.

Penelitian ini bertujuan untuk mengetahui efektivitas pembelajaran kimia melalui pemanfaatan teknologi daring serta mengetahui perbedaan hasil belajar mahasiswa selama pandemi covid-19 menggunakan teknologi daring dibandingkan hasil belajar mahasiswa secara tatap muka/langsung di program studi pendidikan kimia Universitas Nusa Cendana. Metode penelitian yang digunakan adalah metode kombinasi penelitian kuantitatif dan kualitatif. Terdapat perbedaan hasil belajar mahasiswa sebelum pandemi covid-19 (pembelajaran luring) dan selama pandemi covid-19 (pembelajaran daring) pada mata kuliah Kimia Fisik 2, Statistika, Belajar dan Pembelajaran, Pengembangan Program Pembelajaran Kimia, dan Komputer untuk Pembelajaran Kimia, sementara untuk mata kuliah Kimia Dasar 2 tidak ada perbedaan hasil belajar mahasiswa sebelum pandemi covid-19 (pembelajaran luring) dan selama pandemi covid-19 (pembelajaran daring). Nilai rata-rata mahasiswa yang lebih tinggi pada saat pembelajaran daring dibandingkan pada saat pembelajaran luring yaitu mata kuliah Kimia Fisik 2, Statistika, dan Pengembangan Program Pembelajaran Kimia. Itu artinya bahwa pembelajaran daring pada mata kuliah tersebut tergolong efektif. Sementara nilai rata-rata mahasiswa yang lebih tinggi pada saat pembelajaran luring dibandingkan pada saat pembelajaran daring yaitu mata kuliah Belajar dan Pembelajaran dan Komputer untuk Pembelajaran Kimia. Itu artinya pembelajaran daring pada kedua mata kuliah itu masih kurang efektif sehingga perlu diperbaiki segala kekurangan yang ada. Mahasiswa dan dosen lebih cenderung menggunakan perpaduan aplikasi pembelajaran daring yang mudah digunakan guna mendukung kegiatan pembelajaran selama pandemi covid-19, seperti Zoom, Google Meet, Whatsapp, dan E-Learning. Ketertarikan mahasiswa dalam pembelajaran daring masih tergolong cukup. Hal ini dipengaruhi oleh beberapa faktor yang salah satunya adalah mahasiswa kadang-kadang mengalami kendala gangguan internet, sehingga pembelajaran daring menjadi terganggu

The study of chemistry from a cultural standpoint is known as ethnochemistry. If it is used in the learning process, it could improve students' accomplishment and retention in chemistry. Because learners knowledge originates from their own culture. However, the application of culture-based chemistry learning has problems integrating culture with chemistry materials. This is also Relevant with Kakor Village, in South Lembor Sub-district, West Manggarai Regency. So a study was conducted with the aim of examining the chemistry that exists in local cultural products, one of which is songke woven fabric. The research design used is qualitative with an ethnographic approach. The instruments used are observation, interviews and documentation that have been verified. The triangulation methodology was used to confirm the data, and then examined qualitatively, which has three stages: reduction, data presentation, and conclusions. The results demonstrate that chemistry plays a role in the production of songke woven fabric, namely in the phases of the yarn dyeing process when it comes to reaction rates, acid-base balance, and chemical bonding.

The making of traditional woven fabrics has traditionally used natural coloring. But at present, the manufacture of woven fabrics has been greatly influenced by the use of yarn from factories that have been colored with textile dyes. The use of colored yarn from the factory is due to the use of natural materials that fade quickly. The traditional knowledge of natural coloring began to forgotten. The Nekamese area has the potential for plants that can used as natural dyes. In addition, there are also natural ingredients that can be used as a mixture so that the color of woven fabrics does not fade. However, the partners do not have the knowledge and skills to utilize plants as natural dyes for making woven fabrics.
