Efektivitas Penggunaan Herbarium Book Sebagai Media Pembelajaran Morfologi Tumbuhan Terhadap Hasil Belajar Mahasiswa Program Studi Pendidikan BiologiUniversitas Pasir Pengaraian
Get PDFLearning media has an important role in supporting the learning process. An educator must be able to create an effective and fun learning atmosphere. The use of visual media in the form of a herbarium book is one way that can be done. The herbarium book learning media is able to help students understand the material presented, so that learning objectives can be achieved. This study aims to determine the effectiveness of the use of herbarium book as a learning medium on leaf shape material on student learning outcomes in the 3rd semester of Biology at Pasir Pengaraian University. This type of research is a quasi experiment. The design used is a one-group pretest-posttest design. The population in this study were all students of the Biology Education Study Program, FKIP UPP. The research sample was the 3rd semester students of Biology Education FKIP UPP determined by purposive sampling technique. The data analysis technique used validity test, normality test, homogeneity test, and Wilcoxon mean difference using SPSS 16 software. Wilcoxon test obtained sig value. (2-tailed) of 0.000. Because the value of 0.000 is smaller than 0.05 with a mean pretest value of 26.04 and a mean posttest of 68.79, H0 is rejected and Ha is accepted. This means that the herbarium book media is effectively used to improve student learning outcomes of the biology education study program, Faculty of Teacher Training and Education, University of Pasir Pengaraian
Application of Gaussian Naive Bayes Algorithm in Weather Classification of Tanjungpinang City
No full textCuaca mengacu pada kondisi atmosfer sesaat di tempat dan saat tertentu. Cuaca dapat berubah dalam beberapa jam. Cuaca terdiri dari beberapa elemen cuaca. Perkiraan cuaca yang akurat bisa membantu kegiatan sehari-hari warga yang didapat dari klasifikasi yang tepat. Landasan dari klasifikasi Bayes adalah teorema tentang probabilitas bersyarat. Algoritma Naïve Bayes dan algoritma Gaussian Naïve Bayes berbeda satu sama lain. Teknik ini menggabungkan distribusi Gaussian untuk mengatasi perbedaan tersebut. Stasiun Meteorologi Raja Haji Fisabillillah Tanjungpinang menyediakan data suhu, kelembaban, tekanan udara, dan kecepatan angin yang digunakan sebagai parameter penelitian. Data tersebut merupakan data harian yang mencakup periode 1 Januari 2019 hingga 31 Desember 2019 dengan total 365 data. Hasil penelitian dikategorikan ke dalam beberapa kategori cuaca yaitu thunderstorm (TS), Lightning, Mist, lightning rain (TS/RA), Cloudy, rain (RA) dan haze (HZ). Output dari penelitian ini didapatkan akurasi tertinggi sebesar 60,87% dengan jumlah data training sebanyak 50%.Weather refers to the instantaneous atmospheric conditions at a specific place and time. Weather can change within a few hours. Weather consists of several weather elements. Accurate weather forecasts can help the daily activities of citizens obtained from proper classification. The foundation of Bayes classification is the theorem of conditional probability. Naïve Bayes algorithm and Gaussian Naïve Bayes algorithm are different from each other. The Gaussian Naïve Bayes technique incorporates a Gaussian distribution to overcome these differences.

Sosialisasi pencegahan dan penangangan perilaku perundungan di Sekolah Dasar
Get PDFPerilaku Perundungan merupakan suatu fenomena yang cukup meresahkan masyarakat. Hal itu tidak hanya terjadi di lingkungan masyarakat, melainkan terjadi pula pada setiap satuan pendidikan termasuk di SD Inpres Negeri 4 Dobo. Sosialisasi pencegahan dan penaggulangan perilaku dan korban perundungan perlu untuk dilakukan kepada guru-guru di sekolah tersebut. Kegiatan sosialisasi ini bertujuan untuk meningkatkan kesadaran terhadap dampak perilaku perundungan serta pembentukan tim pencegahan perilaku perundungan di sekolah. Kegiatan ini melibatkan guru agama, guru kelas, dan kepala sekolah. Metode yang digunakan pada kegiatan pengabdian ini yaitu sosialisasi dengan teknik pengumpulan data menggunakan kuesioner yang disebar kepada seluruh peserta kegiatan sosialisasi. Data yang diperoleh, dianalisis dengan menggunakan analisis kualitatif dan kuantitatif. Berdasarkan hasil analisis, diketahui bahwa mayoritas guru menghendaki dibentuk layanan khusus penanganan perundungan di sekolah dengan melibatkan orang tua murid, namun mayoritas guru tidak menghendaki pelibatan komite sekolah dalam tim penanganan pencegahan perundungan. Selanjutnya, responden mayoritas mendukung pencegahan dan penanggulangan korban perundungan dan penegakan kode etik atau tata tertib sekolah. Semangat dan motivasi mengikuti seminar atau pelatihan pencegahan dan penangangan perundungan relatif sedang. Fenomena perilaku perundungan di tingkat satuan pendidikan dasar perlu dilakukan pencegahan dan penanganan melalui kerja sama antara pihak sekolah dengan orang tua dengan membentuk tim penanganan dan pencegahan perilaku Perundungan. Peserta kegiatan makin menyadari pentingnya pencegahan dan penanganan kasus perundungan yang terjadi di sekolah
Effect of Sintering Temperature on The Adhesion Quality of Hydroxyapatite on Porous Tantalum for Cancellous Bone Implant Application
Get PDFPorous tantalum has been recently recognized as a conventional orthopedic implant for bone substitute applications besides stainless steel, cobalt-chromium, titanium, and other metallic alloys. Porous tantalum has excellent mechanical and osseointegration properties similar to cancellous bone structure. To optimize the utilization, the dip coating technique was applied to coat porous tantalum with hydroxyapatite (HA). X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques investigate the coating characterization. HA is a bioceramic material that used for bone substitutes due to its chemical and structural similarity to bone minerals. Coated porous tantalum requires the sintering process of porous tantalum to adhere to HA. During the sintering process, various temperatures (650°C, 750°C, 850°C, 950°C, and 1100°C) were used to determine the optimum temperature for porous tantalum coated with HA. The heating rate is 1°C/1 min and the holding time is 60 minutes. The result shows that the optimum temperature of HA-coated porous tantalum is at 850°C. The morphology structure of the HA-coated porous tantalum shows that the adhesion between porous tantalum and HA is in good condition. The element in the HA-coated porous tantalum shows that the existence of HA is high.
