Abstract

Sistem pemintalan elektrik jarum tunggal dan kolektor bidang memiliki kelemahan, yaitu laju produksi yang rendah. Untuk mengatasinya digunakan sistem jarum banyak yang berjejer (multi nozel) dan kolektor berbentuk silinder berputar (kolektor drum). Banyaknya jarum dimaksudkan untuk menambah laju produksi, kolektor drum berputar dimaksudkan agar dihasilkan nanoserat dalam bentuk lembaran yang seragam. Tujuan penelitian adalah untuk menguji pengaruh medan listrik pada proses pemintalan elektrik multi nozel dan kolektor drum berputar, serta mengontrol morfologi nanoserat poli(vinil alkohol)/PVA yang dihasilkan dengan cara mengubah laju alir larutan. Hasil penelitian yang didapat adalah: (1) telah berhasil dibuat nanoserat PVA dalam bentuk lembaran yang menumpuk di kolektor drum, (2) pada pemintalan elektrik dengan sistem multi nozel terjadi distorsi medan listrik pada ujung jarum yang menyebabkan serat pada kolektor tidak rata, (3) morfologi nanoserat PVA yang dihasilkan pada laju alir 0,4 dan 0,6 ml/jam banyak mengandung butiran, sedangkan pada laju alir 0,8 ml/jam jumlah butiran berkurang.ABSTRACTElectrospinning system with single needle and planar collector has the disadvantage of a low productivity. To overcome this problem drum collector and multi-nozzle system were employed. The multi-nozzle system was used to improve the production rate, while the drum collector was used for maintaining the uniformity of the size. The purposes of this study were to examine the influence of electric field in the electrospinning process and to control the morphology of the obtained poly(vinyl alcohol)/PVA nanofibers by changing the solution flow rate. The obtained results were: (1) PVA nanofibers membrane have been successfully produced stacked on the drum collector, (2) distortion of the electric field at the tip of the needle was occurred, which results in inhomogeneous thickness of the stacked nanofibers, and (3) the morphology of the obtained nanofibers at the flow rates of 0.4 and 0.6 ml/hour have many beads while at 0.8 ml/hour the number of beads decreased.

Abstract

Saat ini banyak cara dilakukan untuk meningkatkan kualitas pembelajaran dengan memanfaatkan media pembelajaran yang dirancang sendiri oleh guru. Pada penelitian dirancang media pembelajaran yaitu mengukur viskositas oli menggunakan metode viskositas bola jatuh dengan memanfaatkan dua kumparan sebagai sensor pendeteksi. Dimana dua kumparan dihubungkan dengan osiloskop dan hasilnya diolah menggunakan software freewave3. Dengan memberikan sinyal sinusoidal pada kumparan dan menjatuhkan bola kedalam tabung yang berisi fluida, akan didapatkan informasi perubahan tegangan saat bola tepat melewati kumparan. Dari data yang terekam pada software freewave3 dapat dihitung besar kecepatan terminal bola. Kecepatan terminal bola ditentukan dengan menghitung gradien dari grafik jarak terhadap waktu. Sehingga didapatkan nilai viskositas oli sebesar μ=0.85 Ns/m2. Lembar kerja siswa diuji cobakan pada beberapa mahasiswa dan didapatkan 87,5% mahasiswa menganggap bahwa pengukuran viskositas dengan menggunakan viskometer dua kumparan adalah hal baru bagi mereka, mudah diikuti, mempermudah dalam memahami dan menghitung viskositas fluida, dan memotivasi mereka dalam belajar fisika. Nowadays, there are many ways done to improve quality of learning by taking benefits from learning media designed by teacher. In this research, a viscosity measurement learning media was designed by applying two coils as transducer. Two coils were connected to osciloscop and the result was managed by freeware3 software. By giving sinusiodal signal to the coils dan droping ball into the tube containing oilt, an information of voltage change at the time of the ball passes the coil will be gathered. From the recorded data, the ball terminal velocity can be found by calculating the slope of distance-time graph, with the result of μ=0.85 Ns/m2. Student worksheets were distributed to several students and it was found that 87,5 % of the students considered that the measurement was a new thing for them , easy to follow , make them easier to understand and calculate the viscosity of the fluid , and motivate them to learn physics.

Abstract

Many problems that arise in today's society are rooted in the issue of morality as a result of the marginalization of the values of character. To solve this problem, need to be enforced the values of good character on every member of the community, and the proper way is through the educational process, including through education in schools ranging from elementary education to higher education. To find out whether the teachers in elementary schools are ready to take this work, the research conducted to determine the readiness of teachers and the problems associated with its implementation. Through a questionnaire calculated in descriptive percentage on a sample of elementary school teachers who are spread in Semarang, Semarang District and Temanggung, it can be concluded that in teachers’ view it is very important to integrate the learning of characters in the lesson. However, they need guidance /examples to develop learning model with its features, which integrate the values of the characters in the science subject.Banyak persoalan yang timbul di masyarakat dewasa ini berakar pada persoalan moralitas sebagai akibat terpinggirkannya nilai-nilai karakter, Untuk mengatasi persoalan ini, perlu ditegakkan lagi nilai nilai karakter yang baik pada setiap anggota masyarakat, dan cara yang tepat adalah melalui proses pendidikan, di antaranya melalui pendidikan di sekolah mulai dari pendidikan dasar sampai pendidikan tinggi. Untuk mengetahui apakah para guru pada Sekolah Dasar siap mengemban tugas ini, maka diadakan penelitian untuk mengetahui kesiapan para guru dan masalah-masalah yang terkait dengan pelaksanaannya. Melalui angket yang kemudian diolah secara deskriptive persentasi pada sampel guru SD yang tersebar di Kota Semarang, Kabupaten Semarang dan Kabupaten Temanggung, dapat diketahui bahwa para guru menganggap sangat penting untuk mengintegrasikan pembelajaran karakter dalam matapelajaran IPA. Namun demikian mereka membutuhkan bimbingan/ contoh untuk mengembangkan model pembelajaran dengan fitur-fiturnya, yang mengintergrasikan nilai-nilai karakter dalam mata pelajaran IPA.

Abstract

The direction of current science is emphasized on the importance of science literacy skill as a preparation for students returning to community after finishing school. Science literacy skill is believed can help the individuals to solve the problem scientifically and accountable. Science textbooks are instructional tools that help students learning science. The purpose of this research is to analyse the textbooks of Physics for high school grade X about Optical Instruments topic based on science literacy indicator. The study conducted in four senior highschools. There were two textbooks used in those schools, Book A and Book B. The results showed that on average the emergence of science literacy indicator of science nomenclature was 17.5%, intellectual process skills was 45.5%, the rules of scientific evidence was 8.5%, postulate of science was 19%, and scientific disposition was 9.5%. Book A contained of more research activities than Book B, but Book B linked the second indicator more comprehensive. The advantages and disadvantages of each analyzed textbooks can be used as a further background study for developing the good quality teaching material of physics-based scientific literacy.
