Abstract

Molecular geometry is one of the biggest challenges in science education. Since molecular structures exist at a microscopic level, students often struggle to visualize them in three dimensions (3D), making it difficult to understand concepts such as bond angles, molecular shapes, and electron pair interactions. This study explores the role of spatial ability in high school students’ understanding of molecular geometry. Using a quantitative descriptive method, the study examined the spatial ability and molecular science comprehension of 58 high school students. Data were collected using standardized tests, including the Mental Rotation Test (MRT), shape assembly, and 3D visualization for spatial ability, along with a molecular science comprehension test focusing on VSEPR theory. The results obtain that students' spatial ability is significantly low, with average scores falling far below expected standard. The results suggest the need for more effective teaching strategies that incorporate 3D visualization tools to enhance students’ ability. Future research should focus on interactive learning approaches, such as virtual simulations to help students better visualize molecular structures and improve their understanding of science concepts.

Abstract

Masalah penumpukan sampah yang tidak terkelola dengan baik di Indonesia butuh adanya kesadaran yang tinggi dari masyarakat dalam mendaur ulang sampah melalui sebuah edukasi. Penelitian ini bertujuan untuk merancang prototype website edukasi pengelolaan sampah menggunakan metode design thinking. Tahapan penelitian meliputi empathize untuk mencari tahu kebutuhan pengguna, define untuk mengidentifikasi masalah utama, ideate untuk menghasilkan sebuah ide dan solusi, prototype untuk menciptakan antarmuka yang sesuai dengan kebutuhan pengguna, dan test untuk mengevaluasi hasil antarmuka. Hasil pengujian menghasilkan wawasan dalam perbaikan design sebelum website dikembangkan lebih lanjut. Penelitian ini menunjukkan bahwa metode design thinking merupakan metode yang tepat dan efektif dalam menciptakan ide dan solusi berbasis teknologi yang relevan. Penelitian ini menghasilkan rancangan design UI/UX yang tidak hanya meningkatkan pengalaman pengguna namun juga membantu pemerintah dalam mendukung masyarakat untuk memperoleh edukasi mengenai pengelolaan sampah yang lebih baik dan ramah lingkungan.

Abstract

Masalah pencatatan transaksi penjualan dan persediaan obat-obatan di Apotek X masih dilakukan secara manual, sehingga pekerja sering melakukan dan mendapatkan kesalahan dalam pencatatan transaksi penjualan ataupun stok obat. Kesalahan tersebut meliputi kesalahan menghitung harga yang harus dibayar pembeli, pengembalian uang, dan pencatatan stok obat yang memakan waktu tidak sedikit. Penelitian ini bertujuan untuk merancang prototype yang sesuai dengan kebutuhan pengguna dalam menggunakan sistem apotek berbasis desktop menggunakan metode design thinking. Tahapan design thinking mencakup empathize untuk mengetahui permasalahan yang dialami oleh pengguna, define untuk menganalisis permasalahan yang telah dikumpulkan, ideate untuk menghasilkan ide ataupun solusi kreatif, prototype untuk menghasilkan desain sebagai implementasi ide ataupun solusi yang telah diberikan, dan test untuk mengevaluasi kekurangan apa saja yang terdapat pada prototype tersebut. Hasil dari penelitian ini adalah menghasilkan desain UI/UX yang dihasilkan dengan metode design thinking sehingga dapat meningkatkan efektivitas pekerja dalam melakukan pencatatan transaksi penjualan dan persediaan obat-obatan.

Abstract

Chemical molecules are a challenging topic for students because they are abstract and difficult to visualize. Students continue to struggle with understanding sub-microscopic concepts and lack the analytical skills necessary to solve chemical problems. Spatial and analytical abilities are essential for developing a deeper understanding of chemical molecule structures. This study aims to enhance students' spatial and analytical abilities by applying the Inquiry-Based Learning model using PyMOL as a 3D visualization medium in teaching chemical molecule structures. The method used in this study is a quasi-experiment with a pretest-posttest control group design, involving two groups of tenth-grade classes. The experimental class utilized PyMOL as a 3D visualization medium, whereas the control class employed Molymod kits. The results showed that students who learned using PyMOL experienced significant improvements in both spatial and analytical abilities. Correlation analysis showed a positive relationship between spatial and analytical abilities. Students' responses to the learning process are positive. This study demonstrates that using PyMOL as a medium for technology-based 3D visualization can make abstract concepts easier to understand and help students develop critical and systematic thinking skills.

Abstract

Abstrak — Keamanan pangan merupakan aspek fundamental dalam operasional dapur hotel, mengingat dapur menjadi pusat produksi makanan yang rentan terhadap risiko kontaminasi biologis, kimia, maupun fisik. Untuk itu, sistem Hazard Analysis and Critical Control Points (HACCP) hadir sebagai pedoman internasional yang bertujuan mencegah bahaya sejak tahap penerimaan bahan baku hingga distribusi makanan. Penelitian ini bertujuan untuk menganalisis efektivitas penerapan HACCP di lingkungan dapur hotel serta menilai sejauh mana prinsip-prinsip HACCP berpengaruh terhadap peningkatan keamanan pangan dan efisiensi operasional. Metode yang digunakan adalah penelitian deskriptif-kualitatif dengan pendekatan Systematic Literature Review (SLR), melalui telaah 11 literatur relevan yang terbit pada rentang 2015–2025. Hasil penelitian menunjukkan bahwa keberhasilan penerapan HACCP sangat dipengaruhi oleh pelatihan staf dapur, monitoring titik kendali kritis (CCP), dokumentasi prosedur, serta dukungan manajemen. Penerapan sistem ini terbukti efektif dalam menekan potensi kontaminasi, menjaga kualitas makanan, serta meningkatkan efisiensi kerja dapur hotel. Dengan demikian, HACCP bukan sekadar kewajiban regulatif, melainkan strategi manajemen yang berperan penting dalam menjamin keamanan pangan sekaligus memperkuat daya saing hotel melalui peningkatan kepuasan tamu.
