Abstract

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

Abstract

This study was motivated by the problems that I have found on a mild mental retardation children sitting in class IV C SLB fan-redha Padang. The child is experiencing problems of summation, aims to improve the ability of the sum of integer numbers 1-10 through the media ladder. This study uses a Single Subject Research approach, using AB design and data analysis techniques using visual analysis chart. Subjects were mild mental retardation children fourth grade. Results of analysis of data on baseline conditions (A) shall not exceed six kalipertemuan with the results of 20%, 10%, 0%, 20%, 20%, 20%. A second session interventions (B) observations were made eight times the media ladder observations using numbers as 30%, 50%, 60%, 70%, 70%, 80%, 80%, and 80%. It can be concluded that, the media ladder can improve the ability of the sum of the number of integers 1-10 in children Tunagrahita light in SLB fan-redha Padang. is recommended for teachers to implement the media ladder numbers to increase understanding and summing the mild mental retardation children in mathematics. Kata kunci : Menjumlahkan Bilangan Bulat 1-10, Media Tangga Bilangan, anak tunagrahita ringan, SLB Fan-Redha Padang.

Abstract

Sedimentation is one of coastal dynamic processes. Sedimentation in the mud volcano of Porong at Sidoarjo is an important phenomena to be known as a reference to find out a good solution in the tragedy of mud volcano eruption. Observation of the sedimentation process in the mud volcano eruption of Porong Sidoarjo needs in situ data and data processing technique to know of more details about sedimentation process and the main cause of the sedimentation and the large mud volcano eruption. Therefore, studying of sedimentation process needs the quick timing and high accuracy method. One of the technique which can be used is remote sensing method compared with numerical model and in situ data oservation. Study area is in the Regency of Porong Sidoarjo Province of East Java on August 2008 in position of 7°30’ S - 7°40’ S and 112° 30’ E - 113°30’ E. The aim of this study is to know the pattern of TSM distribution from satellite image using the algorithm which was introduced by Zhou and Kutser. The pattern of TSM from the Landsat and Modis satellite images show that the TSM distribution from the porong river, will then accumulate to the estuary. But, the concentration will decrease in the area that is far from the estuary. This is caused by the influence of the tide current in the Madura strait.From the simulation model was shown that the sediment distribution is influenced by pattern of current generated by tide. High tide where the current move to the upstream sediment in the porong estuary, the sediment was then accumulated in the estuary area. However, at low tide where the current move to the downstream, sediment transportation will move out from the estuary at the maximum level. The pattern of current shows that the moving is to the south direction in the porong coastal that will cause the sediment concentration that out from the porong estuary willgo to to the south direction. The water flow in front of the mouth of porong estuary maybe one of the cause why the sediment distribution tend to move to the south direction.

Abstract

Abstrak. Penelitian ini mengambil judul Efektifitas Pungutan Pajak Bumi Dan Bangunan Perkotaan Dan Perdesaan (PBB-P2) Terhadap Peningkatan Pendapatan Asli Daerah Kabupaten Mamuju. Berdasarkan judul yang dikemukakan diatas maka adapun yang menjadi tujuan penelitian adalah ingin mengetahui Efektivitas Pemungutan Pajak Bumi Dan Bangunan Perkotaan Dan Perdesaan (PBB-P2) Terhadap Peningkatan Pendapatan Asli Daerah Kabupaten Mamuju. Berdasarkan hasil olah data yang ada hasil yang dapat dijelaskan adalah bahwa dari tahun 2015-2019 tingkat efektivitas dari pajak bumi dan bangunan perkotaan dan perdesaan yang terealisasi masih sangat jauh dari persentase yang ditargetkan, hal ini dapat dilihat dari hasil olah data yang menunjukkan bahwa dari tahun 2015-2019 pajak yang diperoleh semuanya hanya mencapai persentase dibawah 50% dan ini juga menunjukkan bahwa pungutan pajak yang masuk pada badan pendapatan daerah Kabupaten Mamuju pada periode tersebut masih jauh dari kriteria efektif apalagi kriteria sangat efektif.
