Abstract

In this paper, we investigate a hexagonal two-layer photonic crystal fiber based on surface plasmon resonance (HT-PCF-SPR) which is easy to fabricate as a sensor for detecting the refractive index of analytes. After performing numerical simulations using COMSOL multiphysics based on the finite element method (FEM), it was found that the HT-PCF-SPR could detect the analyte's refractive index in the range 1.34-1.37 RIU and in the wavelength range from 730 nm to 810 nm. The plasmonic material used in the design is gold with a thickness of 40 nm which is located outside the layer and in two opposite air holes in the core. The HT-PCF-SPR design has good performance in detecting analytes, it is found that the sensitivity in detecting analytes is 2,000 nm/RIU, meaning that every 1 RIU shift of analyte shifts the wavelength by 2000 nm. Meanwhile, the sensor resolution obtained from the design is 6.67×10-5 RIU, and it is found that the larger the air hole, the greater the confinement loss value.

Abstract

Musa balbisiana Colla in Kuantan Singingi Regency can survive from the disease that cause banana in many other areas loss their diversity. Currently, there is no information about the diversity of M. balbisiana from Kuantan Singingi. The purposes of this study were to record, characterize, and measure the diversity of M. balbisiana from Kuantan Singingi based on the morphological characters. M. balbisiana Colla samples were collected from three locations in kuantan singingi, i.e. Pangean, Cerenti, and Inuman. A total of 88 morphological characters of M. balbisiana were analyzed. The UPGMA analysis was conducted to find out the diversity of M. balbisiana. The result showed that there were six M. balbisiana cultivars, namely Aceh, Bungo, Kara, Jambi, Nipah, and Beluluk which were found in this study. The similarity coefficient values of these six banana cultivars was ranged from 63-89 %. Cluster analysis based on 88 morphological characters of M. balbisiana produced dendogram with 2 primary groups at percentage of similarity values of 66 %.  Kara cultivar contained the highest carbohydrates, vitamin C, fiber and sodium content, while aceh cultivar had the highest potassium content. Key words: diversity, Kuantan Singingi, morphology, M. balbisiana, nutrient content

Abstract

Pulau Rupat adalah pulau kecil di wilayah Sumatra yang memiliki keanekaragaman hayati tinggi. Salah satu flora di Pulau Rupat adalah bambu. Bambu memiliki kemampuan beradaptasi tinggi terhadap kondisi asam pada lahan gambut, tetapi informasi tentang spesies bambu di Pulau Rupat belum pernah dilaporkan. Tujuan dari penelitian ini adalah untuk mengetahui keanekaragaman spesies dengan mengidentifikasi dan memeriksa berdasarkan kunci identifikasi karakter morfologi. Metode penelitian yang digunakan adalah survey eksploratif. Hasil inventarisasi mengidentifikasi total sembilan spesies dari empat genus (Bambusa vulgaris, Bambusa vulgaris var. striata, Bambusa heterostachya, Bambusa multiplex, Gigantochloa sp., Gigantochloa cf. velutina, Gigantochloa hasskarliana, Schizostachyum brachycladum, Schizostachyum zollingeri, Thyrsostachys  siaminensis). Sebanyak sepuluh aksesi bambu diamati karakter vegetatifnya. Hasil skoring 53 karakter tersebut dianalisis menggunakan program NTSYSPC 2.02 untuk mengetahui pengelompokkannya. Hasil penelitian menunjukkan koefisien kemiripan berkisar 48%-77%.
