"One of factors that could influence the degree of degree of conversion of composite restorative material is light intensity. Many researchers have done investigation on the degree of conversion of hybrid, microfiller and microhybrid composite. However, there are still minimum researches on the influence of light intensity on the degree of conversion of nano particle composite which is one of the universal composite that has been developed in dentistry. The used material was Supreme XT nano particle composite (3M ESPE German). Cylindrical specimens with 33 mm in diameter, 2 and 3 mm thickness were prepared. Specimens were cured by Light Emitting Diode (LED) with light intensity variation of 1120, 1040, 800, 560 and 480 mW/cm2, and then incubated for 24 hours at 37°C. Fourier Transform Infra Red (FTIR) was used to determine the degree of conversion. The data were analyzed statistically by using two-way anova and tukey post hoc test. Based on statistic result at a = 0.05 light intensity variation gave significant difference on the degree of conversion of nano particle composite. The highest degree of conversion was achieved with 800 mW/cm2 light intensity, which is 89.67%. The 2 and 3 mm thickness gave no significant difference on the degree of conversion. This research shows that the variation of light intensity has significant influence towards the degree of conversion of nano particle composite."

"Gempa Sumatera 30 September 2009 telah merusak ratusan ribu bangunan di Provinsi Sumatera Barat. Gempa tersebut berlokasi di 100 km lepas pantai dari Kota Padang, ibu kota provinsi tersebut. Survei telah dilakukan untuk menilai kerusakan bangunan dalam beberapa hari setelah gempa. Dalam survei ini, kerusakan bangunan dikategorikan menjadi 3 tingkat yaitu berat, sedang, dan ringan. Tulisan ini membahas tingkat kerusakan bangunan dan intensitas getaran di daerah yang terkena. Selanjutnya berdasarkan koordinat dari setiap lokasi, bangunan yang disurvei diplotkan di dalam sebuah peta bersamaan dengan tingkat intensitas. Hubungan antara tingkat kerusakan dan intensitas gempa untuk Sumatera Barat selanjutnyadibuatkan. Hubungan unik kerusakan-intensitas ini merupakan hal yang sangat penting digunakan dalam memprediksi tingkat kerusakan akibat gempa tertentu. Tingkat kerusakan tersebut dibutuhkan oleh pemerintah untuk menyusun rencana anggaran pada tahap tanggap darurat dan rekonstruksi untuk bencana gempa di masa yang akan datang.

AbstractThe Sumatra 30 September 2009 earthquake has damaged hundred thousand buildings in West Sumatra Province. The earthquake is located in 100 km offshore of Padang City, the Capital City of the province. Survey has been conducted to assess the damage of the building in few days after the earthquake. In this survey, the damage of buildings are categorised into 3 level that are heavily, moderate and slightly damages. This paper explores the level damage of building and then the intensity of the shaking in the affected area. Then based on the coordinate of every building location, the buildings are scattered in a map together with the intensity level. The relationship between the damage level and intensity for West Sumatra then is developed. This special damage-intensity relation is very important to beused for predicting the damage level due to a specified earthquake. The damage level is needed by The Government to develop an emergency and reconstruction budget plan for earthquake disaster in future. "

"Manusia terlahir dengan kemampuan luar biasa dalam menerima dan mengartikan informasi yang mereka terima dari lingkungan sekitar nya. Penilitian ini berfokus lebih mendalam mengenai kemampuan persepsi manusia terhadap stimuli musik yang berhubungan dengan aspek ketertarikan, ekspresi, dan kenikmatkan. Penilitian ini bertujuan untuk mencari tahu efek dari manipulasi bentuk presentasi music dalam penilaian partisipan atau pendengar terhadap stimuli music yang diberikan.Desain penelitian eksperimen antar subjek (within-subject design study) telah digunakan untuk mendelegasi partisipan (N = 60) dari berbagai umur (M = 20,15, SD = 5,10) dan latar belakang pengetahuan musik, kedalam 2 presentasi music berbeda; hanya audio, dan audio dan visual. Hasil penelitian mengindikasi hipotesa yang terdukung bahwa skor penilaian partisipan akan semakin tinggi ketika diberikan stimuli musik dalam rupa audio dan visual. Dapat disimpulkan, penilaian estetik partisipan terhadap penampilan musik yang diberikan terpengaruh dengan presentasi visual nya ketika dibandingkan dengan penampilan musik yang hanya berupa suara tanpa visual.

Humans are gifted with an incredible ability to receive and perceive information from their surround environment. This study focuses on human’s perception towards music stimuli in related to their interest, expressiveness, and enjoyment. The aim of the study is to figure out the effect of presentation manipulation on audience’s or participants’ judgment towards the given musical performance. A within-subject design study was conducted by delegating participants (N = 60) from varying age (M = 20,15, SD = 5,10) with different musical background, into 2 different musical presentation; audio-only and audio-visual. The result indicated a supported hypothesis in related to higher score of participant’s judgments when given and exposed to an audio-visual presentation of the music performance. In conclusion, audience’s and participant’s judgment on the music performance is affected even more significant by the present of the visual compared to being exposed only to the audio stimuli."
