Pengaruh Tingkat Kepadatan Kandang terhadap Eritrosit, Hemoglobin, dan Hematokrit Broiler Sistem Closed House
No full textKepadatan kandang merupakan salah satu faktor manajerial yang secara langsung mempengaruhi performa, kesejahteraan, dan parameter fisiologis ayam broiler. Sistem Closed House menawarkan kontrol lingkungan yang optimal sehingga memungkinkan penerapan kepadatan tinggi tanpa mengorbankan kesehatan ayam. Meskipun demikian, batasan kepadatan optimal yang tidak berdampak negatif terhadap kondisi hematologis ayam broiler masih menjadi perdebatan. Penelitian ini bertujuan untuk mengkaji pengaruh tingkat kepadatan kandang terhadap jumlah eritrosit, kadar hemoglobin, dan nilai hematokrit ayam broiler strain Ross dalam sistem pemeliharaan Closed House. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan kepadatan yaitu 8, 10, dan 12 ekor/m²; masing-masing terdiri atas lima ulangan. Data dianalisis dengan metode analisis ragam (ANOVA) dan dilanjutkan dengan uji Duncan apabila terdapat perbedaan nyata. Hasil penelitian menunjukkan bahwa terdapat pengaruh yang tidak signifikan (P>0,05) dari tingkat kepadatan terhadap ketiga parameter hematologi yang diamati. Temuan ini menunjukkan bahwa ayam broiler mampu beradaptasi dengan rentang kepadatan 8–12 ekor/m² tanpa mengalami gangguan fisiologis yang berarti. Faktor pengelolaan lingkungan dalam sistem Closed House berperan krusial dalam mempertahankan stabilitas hematologis ayam. Oleh karena itu, dapat disimpulkan bahwa penerapan kepadatan kandang 8–12 ekor/m² pada sistem Closed House masih berada dalam batas aman dan tidak memengaruhi status hematologi ayam broiler strain Ross

When Students Encounter PISA Questions: From the Perspective of 4C Skills
No full textPISA is a prestigious platform for assessing students\u27 learning achievements globally, including 4C skills: creative thinking, critical thinking, communication, and collaboration. However, the 2022 PISA results once again showed disappointing achievements for Indonesia. Indonesian students struggle with solving complex problems (critical thinking), have difficulty conveying ideas effectively (communication), are less prepared for creative challenges (creative thinking), and lack effective collaborative learning approaches. This research aimed to analyze the 4C skills of students at SMP Negeri 31 Medan. The study involved 29 students from class IX-3. Data were collected using two selected essay questions from the 2022 PISA mathematics test, specifically designed to assess 4C skills through indicators like interpreting, formulating, and reasoning. Collaboration was assessed through semi-structured interviews with the class teacher to gain insights into students\u27 interaction and teamwork skills, complementing the written test results. Qualitative descriptive analysis was used to interpret students\u27 written responses, while collaboration data were analyzed based on teacher observations. Assessment criteria followed established indicators for critical thinking (Employ and Evaluate), creativity (formulate), communication (interpret), and collaboration (effective teamwork). The results indicate that 69.56% of students correctly answered interpretation questions (communication, level 3), 39.13% and 43.47% answered employability questions correctly (critical thinking, levels 2 and 1a), and 30.43% correctly answered formulation questions (creativity, level 2). However, teacher observations revealed that students still struggle with effective collaboration, reflecting a broader challenge in fostering teamwork and peer learning. Overall, although communication skills are relatively strong, significant improvements are needed in critical thinking, creativity, and collaboration
Analisis Pengaruh Data Augmentasi Pada Klasifikasi Tenun Menggunakan Deep Learning Berbasis Convolutional Neural Network: Analisis Pengaruh Data Augmentasi Pada Klasifikasi Tenun Menggunakan Deep Learning Berbasis Convolutional Neural Network
No full textThis research develops a classification model of Timorese weaving motifs using Deep Learning method based on Convolutional Neural Network (CNN). Timor\u27s diverse weaving motifs reflect the richness of local culture, but manual classification takes a long time and is prone to subjectivity. To improve model performance, Data Augmentation techniques, such as flipping, rotation, and zooming,, are applied to enrich the variety of pre-processed Timor weaving image datasets. In addition, the CNN model was developed using Transfer Learning techniques to improve training efficiency.
Experimental results show that CNN without augmentation achieves 95.00% accuracy, 95.00% precision, 95.08% recall, and 95.04% F1-score, with a computation time of 2.37 minutes at 30 epochs. Meanwhile, applying Data Augmentation increased the model accuracy to 96.66%, precision 96.66%, recall 96.87%, and F1-score 96.77%, and reduced the computation time to 2.11 minutes.
Analysis of the effect of augmentation data shows that increasing the variety of images contributes to the improvement of model generalization. Therefore, the use of CNN with Data Augmentation is a more optimal solution in the classification of Timorese weaving motifs. This research has the potential to support cultural preservation as well as the development of an artificial intelligence-based weaving motif identification system

SINTESIS ZnO BERSTRUKTUR NANO MENGGUNAKAN CAMPURAN PELARUT AIR-ETILEN GLIKOL DAN KARAKTERISASI STRUKTUR, MORFOLOGI DAN ENERGI CELAH PITA PARTIKEL
No full textSeng oksida (ZnO) adalah salah satu material semikonduktor yang banyak diaplikasikan dalam berbagai bidang, salah satunya adalah sebagai fotokatalis. Karakteristik penting untuk menunjang aplikasi ZnO sebagai fotokatalis adalah luas permukaan dan densitas cacat kristal. Penelitian ini bertujuan untuk meningkatkan potensinya sebagai fotokatalis dengan cara mengontrol morfologi dan densitas cacat kristal melalui sintesis menggunakan campuran pelarut air-etilen glikol. Struktur partikel hasil sintesis dikarakterisasi menggunakan difraksi sinar x (XRD), morfologinya diamati menggunakan Field Emission Scanning Electron Microscope (FESEM), dan energi celah pita partikel ditentukan menggunakan persamaan Kubelka-Munk berdasarkan spektrum absorpsi yang diukur manggunakan UV-Vis Diffuse Reflectance Spectroscopy (DRS). Hasil penelitian menunjukkan bahwa ZnO berstuktur kristal wurtzite dengan morfologi tiga dimensi berstruktur nano berhasil disintesis menggunakan campuran pelarut air-etilen glikol dengan keberadaan urea sebagai agen penghidrolisis. Etilen glikol berperan sebagai capping agent yang teradsorpsi ke permukaan kristal ZnO, sehingga mengarahkan petumbuhan kristal anisotropik dan menghasilkan ZnO berstruktur nano. Meskipun ZnO hasil sintesis memiliki energi celah pita lebar (3,16 eV), keberadaan cacat kristal dapat meningkatkan performanya dalam berbagai aplikasi jika dibandingkan dengan ZnO konvensional. Karakteristik material yang dihasilkan menunjukkan bahwa partikel ZnO hasil sintesis berpotensi memiliki kinerja unggul dalam aplikasinya sebagai fotokatalis
