<![CDATA[Photo-responsive molecule Sudan III has been developed in form of thin film to pursue their excellent properties especially for optical sensor device application. However, thin film of Sudan III possesses a weak mechanical property. And therefore in order to enhance this functional property of the Sudan III molecule was embedded within polymer matrix to form composite material. In this research, the thin films composite of Sudan III-Poly(N-Vinylcarbazole) or Sudan III/PVK were fabricated by using casting and spin coating methods. The structure of Sudan III-Poly(N-Vinylcarbazole) composite material were characterized by using FTIR, XRD measurement and for the optical property (absorbance) by UV-VIS measurement. In this paper the experiment results are presented]]>

<![CDATA[Tujuan dilakukannya penelitian ini adalah untuk mengkaji efek permukaan substrat ITO dan medan listrik luar dalam mengatur orientasi molekul film DR-1; dan juga mengkaji sifat optik film DR-1 untuk aplikasi divais fotonik. Metode fabrikasi yang digunakan adalah metode EFA-PVD (Electric Field Assisted Physical Vapor Deposition,). Metode tersebut adalah modifikasi dari metodekonvensional PVD (Physical Vapor Deposition) yang dilengkapi dengan penambahan medan listrik luar (E) dalam chamber. Film dibuat di atas permukaan substrat ITO (Indium Tin Oxide) dengan deposisi molekul-molekul DR-1 oleh variasi medan listrik luar. Film dianalisis dan dikarakterisasidengan menggunakan spektroskopi SEM, difraksi sinar-X, dan reflektometer. Hasil analisis pengukuran SEM, dan difraksi sinar-X memperlihatkan bahwa molekul-molekul DR-1 tersusun teratur (stacking) tegak lurus permukaan substrat, yang menunjukkan suatu indikasi efek permukaan (surfactant effect) substrat yang kuat dari ikatan hidrogen (hydrogen bonding) molekul DR-1 dengan substrat. Hasil pengukuran sifat optik menunjukkan bahwa dengan peningkatan medan listrik luar, terjadi peningkatan konsentrasi molekul-molekul DR-1 yang terdeposisi teratur paralel (stacking) tegak lurus permukaan substrat yang ditandai dengan peningkatan indeks bias film.Kata kunci: Disperse red-1. EFA-PVD, stacking, ikatan hidrogen]]>

<![CDATA[Perkembangan penggunaan material/bahan bangunan rumah dengan menggunakan atap seng berbasis baja ringan semakin pesat karena dengan menggunakan material tersebut lebih tahan lama dan relatif lebih cepat pekerjaan diselesaikan. Namun demikian pengerjaan konstruksi bangunan/rumah/garasi dengan atap seng berbasis baja ringan diperlukan pengetahuan tentang material, disain dan konstruksi serta ketrampilan dalam pembuatannya. Berdasarkan pengamatan kami bahwa, Masyarakat-Tukang di Kelurahan Titiwungen Selatan, Kecamatan Sario Kota Manado kalah bersaing dengan tenaga kerja dari luar daerah dalam mengerjakan konstruksi bangunan/rumah dengan atap seng berbasis baja ringan karena mereka hanya terbiasa dengan mengerjakan atap seng berbasis kayu (konstruksi dengan bahan kayu). Disamping kekurangan tentang pengetahuan disain dan kosntruksi atap seng dengan baja ringan mereka juga belum memiliki ketrampilan serta peralatan seperti bor-elektrik. Dengan demikian mereka kehilangan peluang kerja sehingga sangat berdampak pada masalah ekonomi/pendapatan keluarga. Melalui Pendidikan dan Latihan Kerja merupakan solusi tepat yakni memberikan pengetahuan dan ketrampilan bagi masyarakat-tukang agar mereka boleh bersaing dan mendapat peluang kerja dan akhirnya dapat meningkatkan pendapatan keluarga. Melalui PKM Latihan Kerja ini para tukang (masyarakat) di Kelurahan Titiwungen Selatan Kecamatan Sario Kota Manado telah berhasil meningkatkan pengetahuan dan ketrampilan membuat disain dan konstruksi atap seng berbasis baja ringan. Para tukang (masyarakat) di Kelurahan Titiwungen Selatan Kecamatan Sario Kota Manado menyarankan agar PKM Latihan Kerja ini kiranya dapat di kembangkan untuk pola /disain konstruksi yang lebih variatif.]]>

<![CDATA[Abstract. Highly crystalline thin films of photorefractive Disperse Red 1 (DR 1) molecule have been fabricated on clean substrate of ITO (indium tin oxide) glass by means of physical vapor deposition at various substrate temperatures. In addition to molecular orientation and organization revealed by their XRD and FTIR spectral characteristic and the enhancement of those effects by substrate temperature, further analysis of FTIR spectrum around nitrobenzene absorption band indicates the formation of strong hydrogen bond resulting in a head-tail stacking of the molecules. The deposited films also show systematic reduction of light absorption in the visible region with increasing substrate temperature. This modification of the optical property is clearly favorable for long wavelength photonic applications of DR1 film. Pengaruh Suhu Substrat pada Film Tipis 'Disperse Red 1' yang Dideposisi pada Gelas ITO dalam VakumSari. Dalam eksperimen ini telah berhasil diperoleh melalui proses deposisi vakum sejumlah film tipis bahan fotorefraktif dari molekul "Disperse Red 1" (DR1) dengan krisalinitas tinggi di atas substrat gelas ITO ("indium tin oxide") pada berbagai suhu. Selain efek orientasi dan organisasi molekul yang ditunjukkan oleh karakteristik spectra XRD dan FTIR bersangkutan serta peningkatan efek tersebut dengan suhu substrat, analisis lebih lanjut dari data FTIR di sekitar pita absorpsi nitrobenzene telah mengungkapkan tanda embentukan ikatan hydrogen yang kuat yang menghasilkan susunan "head-tail" yang bertumpuk. Film yang terdeposisi juga memperkihatkan pengurangan absorpsi cahaya secara sistematik di daerah tampak, seiring dengan peningkatan suhu substrat. Perubahan sifat optik ini jelas bermanfaat bagi aplikasi film DR1 untuk devais fotonik dalam daerah gelombang panjang.]]>

<![CDATA[The Probabilistic Seismic Hazard Analysis (PSHA) method is a method used in seismic hazard analysis based on the definition of a probability distribution function that takes into account and combines the uncertainties of the earthquake event scale, location, and frequency of occurrence, to obtain a comprehensive picture of the hazard level or a location that reviewed. The Likupang area, North Minahasa is a location that is prone to earthquake disasters, for this reason, early mitigation is needed, one of which is mapping the potential for disaster hazards. Maximum ground vibration acceleration (PGA) is the greatest value of ground acceleration at a place caused by earthquake vibrations in a certain period of time. In this study, the results of the PSHA calculation in the North Minahasa Likupang area were obtained, the largest PGA value was 1.4g–1.8g, tilapia SA T= 0.2 seconds was 1.7g-2.1 and SA T=1 value, 0 seconds is 0.5g – 0.6g. Based on these results, the danger of light to severe damage can be caused.]]>
