ABSTRAK Muhammad Fahmi Al Amiq. PEMBELAJARAN LUKIS PADA TOTEBAG DALAM MATA PELAJARAN SENI BUDAYA DI KELAS X MIA 3 SMA NEGERI 3 BOYOLALI TAHUN AJARAN 2017/2018. Skripsi, Fakultas Keguruan dan Ilmu Pendidikan, Universitas Sebelas Maret Surakarta, Januari 2018. Tujuan penelitian ini adalah untuk mengetahui: (1) Proses pelaksanaan pembelajaran Lukis Totebag di kelas X MIA 3 SMA Negeri 3 Boyolali tahun ajaran 2017/2018. Dan (2) Bagaimana bentuk hasil karya Lukis Totebag yang dihasilkan siswa di kelas X MIA 3 SMA Negeri 3 Boyolali tahun ajaran 2017/2018. Penelitian ini menggunakan pendekatan kualitatif. Sumber data yang digunakan adalah informan yang dipilih yaitu Bapak Subandiyo S.Pd selaku guru mata pelajaran seni budaya di kelas X MIA 3 SMA Negeri 3 Boyolali, serta foto proses pembelajaran, hasil karya siswa dan dokumen arsip. Teknik yang digunakan dalam pengumpulan data adalah observasi langsung, wawancara terstruktur dan mendalam, serta dokumentasi. Uji validitas data dilakukan dengan membandingkan sumber data yang di peroleh berupa daftar hasil wawancara dengan Bapak Subandiyo S.Pd selaku guru mata pelajaran Seni Budaya dengan siswa di kelas X MIA 3 SMA Negeri 3 Boyolali, serta review informant. Analisis data yang digunakan adalah model analisis mengalir, yaitu: reduksi data, sajian data, dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa: (1) Pembelajaran Lukis Totebag diawali dengan pembuatan RPP, selanjutnya pembelajaran dilaksanakan selama tiga kali pertemuan. Strategi yang digunakan guru dalam pembelajaran ini adalah pendekatan scientific. Metode pembelajaran yang digunakan meliputi metode ceramah, tanya jawab, diskusi, dan pemberian tugas. Media pembelajaran yang digunakan berupa slide power point dan media visual berupa sampel karya dari guru. Evaluasi pembelajaran dilakukan dengan menilai aspek kognitif, afektif, dan psikomotorik. Proses pembuatan karya dilakukan dengan beberapa langkah, yaitu membuat sketsa, proses pewarnaan, dan finishing. (2) Secara umum pembuatan karya lukis totebag siswa sudah baik, teknik lukis pada pewarnaan dan finishing dalam membuat karya lukis totebag sudah baik.

Quasi-Two-Dimensional SiC and SiC<sub>2</sub>: Interaction of Silicon and Carbon at Atomic Thin Lattice Plane
The
band gap of graphene is nearly zero, and thus novel two-dimensional
(2D) semiconductor and band gap engineering of graphene is highly
desired for advanced optoelectronic applications. Herein, we have
experimentally produced quasi-two-dimensional (quasi-2D) SiC by reaction
between graphene and a silicon source, which was designed and supported
by Born–Oppenheimer molecular dynamics simulations. The lateral
length of the as-synthesized quasi-2D SiC is mainly in the range of
0.3–5 μm while the thickness is commonly below 10 nm.
Quasi-2D SiC<sub>2</sub> is also found as a byproduct, which is stable
over 3 months in air atmosphere. The exciton binding energy of quasi-2D
multilayers SiC can reach 0.23 eV while the band gap is around 3.72
eV. Additionally, in situ transmission electron microscopy has firmly
proven that quasi-2D SiC can be synthesized through the reaction between
graphene and silicon quantum dots. The first production of quasi-2D
SiC and SiC<sub>2</sub> makes the band gap engineering in the graphene
lattice plane possible
Triboelectrification-Induced Large Electric Power Generation from a Single Moving Droplet on Graphene/Polytetrafluoroethylene
Recently,
several reports have demonstrated that a moving droplet of seawater
or ionic solution over monolayer graphene produces an electric power
of about 19 nW, and this has been suggested to be a result of the
pseudocapacitive effect between graphene and the liquid droplet. Here,
we show that the change in the triboelectrification-induced pseudocapacitance
between the water droplet and monolayer graphene on polytetrafluoroethylene
(PTFE) results in a large power output of about 1.9 μW, which
is about 100 times larger than that presented in previous research.
During the graphene transfer process, a very strong negative triboelectric
potential is generated on the surface of the PTFE. Positive and negative
charge accumulation, respectively, occurs on the bottom and the top
surfaces of graphene due to the triboelectric potential, and the negative
charges that accumulate on the top surface of graphene are driven
forward by the moving droplet, charging and discharging at the front
and rear of the droplet
