Penelitian ini bertujuan untuk mengetahui karakteristik material organik pengganti fantom polymethyl methacrylate (PMMA) dan fantom air dengan parameter backscatter factor (BSF) dan koefisien atenuasi linear (m). Pengukuran BSF dan m dilakukan menggunakan mobile X-Ray dengan faktor eksposi 40-120 kV dengan dua puluh variasi kualitas berkas pada tiga luas lapangan yang berbeda (untuk pengukuran BSF). Hasilnya, fantom organik memiliki nilai BSF yang mendekati fantom standar dengan deviasi < 8% dan < 10%, berturut-turut untuk fantom ekuivalen air dan PMMA. Sementara nilai m untuk fantom-ekuivalen air pada tegangan > 60 kV memiliki tingkat kesalahan < 15% untuk fantom ekuivalen air dan < 18% untuk fantom ekuivalen PMMA. ...... This research aims to verify physical characteristics of water and polymethyl methacrylate (PMMA)-equivalent phantom made of organic materials in terms of its interaction with diagnostic-range radiation. Backscatter factor (BSF) and linear attenuation coefficient (m) were selected as test parameters. Measurement of BSF and m has been performed using mobile x-ray beam with the exposure factor of 40 to 120 kV. For BSF, measurement has been carried out using twenty different beam qualities in three different field sizes. The final results show similarity between water equivalent-phantom and the literature with the error below 8% and below 10% for the PMMA equivalent-phantom. The results of m measurement for water equivalent phantom in the beam voltage above 60 kV shows error below 15% compared to standard water phantom. On the other hand, PMMA quivalent-phantom shows an error below 18%.

In addition, graphene and MAXene in PCM composites were produced through the wet impregnation method to determine the effect of nanoparticles. Natural wax used is soy wax, paraffin wax, and palm wax. Graphene and MAXene (Ti3AlC2) nanoparticles were added at 0.1-1 wt.% to the PCM to increase the thermal conductivity and thermal stability of the nano-PCM composite.

Seiring dengan perkembangan zaman dimana kebutuhan manusia semakin meningkat dan semakin kompleks, teknologi merambat ke semua bidang ilmu pengetahuan, termasuk arsitektur. Ironisnya, kemajuan teknologi justru seperti menarik manusia menjadi semakin jauh dari alam, seperti apa yang terjadi pada masa Revolusi Industri, dimana semua terlihat sama dan diproduksi secara massal, semata-mata hanya untuk memenuhi kebutuhan manusia. Manusia tidak lagi memikirkan cara agar dapat hidup harmonis dengan alam seperti yang dilakukan oleh para leluhur mereka dahulu. Arsitektur dapat menjadi salah satu wadah yang memfasilitasi manusia agar dapat kembali dekat dengan alam, yang seringkali dilakukan oleh para arsitek dengan cara mengambil bentuk atau material yang ada di alam. Inilah asal mula munculnya gagasan tentang arsitektur organik. Terdapat berbagai unsur yang dapat membuat arsitektur disebut sebagai arsitektur organik, dimana unsur yang dominan adalah bentuk dan material yang organik. Namun, seiring dengan perkembangan zaman, terjadi pergeseran dominansi unsur dalam arsitektur organik. ......Throughout the progress of time where human needs are increasing and becoming more complex, technology propagates all field of knowledge, including architecture. Ironically, technological development seems to pull humans further from nature, just like what happened during the Industrial Revolution, which all objects looked the same and were mass produced, for the sole purpose of fulfilling human needs. People have no longer thought about ways to live in harmony with nature as their ancestors did. Architecture can become the vessel that facilitates people to return to nature, by taking the form of objects that are found in nature or using materials that are also found in nature. This is how the idea of organic architecture originated. There are various elements that can make an architecture to be referred as organic architecture, where the dominant elements are organic form and organic material. However, throughtout the progress of time, there is a shift in elemental dominance in organic architecture.
