Kemampuan melaksanakan kegiatan praktikum/demonstrasi dan mengembangkan materi pembelajaran berbasis laboratorium adalah salah satu kompetensi guru fisika. Peningkatan kemampuan tersebut akan meningkatkan daya saing lulusan siswa. Tujuan pelaksanaan kegiatan pengabdian pada masyarakat ini adalah: 1) memperkenalkan pengetahuan tentang laboratorium Fisika material dan Riset bagi guru Fisika SMA se kota Manado; 2) memberikan pelatihan keterampilan penggunaan peralatan laboratorium Fisika material dan riset bagi guru Fisika SMA se kota Manado; 3) menjelaskan manfaat karakterisasi peralatan laboratorium Fisika Material dan Riset bagi guru Fisika SMA se kota Manado; dan 4) menjalin kerja sama antara dunia kerja yaitu Sekolah dengan Perguruan Tinggi (UNIMA) agar tercipta keserasian tentang kebutuhan Sumber Daya Manusia dilapangan dan kurikulum yang diterapkan khususnya pada Program Studi Fisika FMIPA UNIMA. Metode yang dilakukan adalah ceramah, demonstrasi, peragaan, diskusi dan evaluasi. Kegiatan ini akan menghasilkan produk berupa buku panduan bagaimana dan apa yang harus dilakukan dalam mengoperasikan peralatan laboratorium fisika material dan riset. Buku panduan akan dirancang semenarik mungkin disertai gambar dan keterangan serta langkah-langkah dalam mengoperasikan alat laboratorium. Disamping buku panduan, akan dibuat juga buku ajar tentang konsep dan teori terkait dengan peralatan laboratorium fisika material dan riset serta artikel ilmiah. Berdasarkan kegiatan yang dilaksanakan, maka diperoleh hasil sebagai berikut: 1) para peserta (Guru fisika SMA) mengenal pengetahuan tentang spektroskopi UV-Vis (Ultra Violet Visible); 2) memahami pengetahuan tentang spektroskopi FTIR (Fourier Transform Infra red); 3) mengenal pengetahuan tentang SEM-EDX (Scanning Electron Microscopic-Energy Dispersive X-Ray Spectrometric); dan 4) mampu mengoperasikan alat spektrometer UV-Vis, FTIR, dan SEM-EDX.

Results are presented of microtopographical studies on rare-earth orthoferrite RFeO3 (R = Dy, Ho) crystals by scanning electron microscopic and energy-dispersive x-ray analytical (EDAX) techniques. The flux growth yields crystals with habit faces. These crystals are therefore suitable for surface structural studies.The crystals of RFe03 (R = Dy, Ho) are grown from starting compositions of R203, Fe203 (solute), Pb0, PbF2 (solvent), and B203 (additive) in a platinum crucible; the growth procedure has been reported previously. Figures 1 and 2 illustrate platinum deposits on an HoFe03 surface. The modification of advancing growth fronts by an imperfection on an HoFe03 surface is illustrated in Fig. 3.X-ray mapping and elemental line profiles taken across some peculiar structures on an RFe03 crystal indicate that the areas covered by the structures are rich in R but deficient in Fe. Almost the same observations were made on DyFe03 crystals. It is concluded that use of PbO-PbFe2-B203 flux systems for the growth of RFe03 (R = Dy, Ho) results in the precipitation of magnetoplumbite (PbFe12019) and R0F.

Although scanning electron microscopy has a great potential in biological application, there are certain limitations in visualization of the biological structure. Satisfactory techniques to demonstrate natural surfaces of the tissue and the cell have been reported by several investigators. However, it is commonly found that the surface cell membrane is covered with a minute amount of mucin, secretory substance or tissue fluid as physiological, pathological or artefactual condition. These substances give a false surface appearance, especially when the tissue is fixed with strong fixatives. It seems important to remove these coating substances from the surface of the cell for demonstration of the true structure.
