Analisis Stabilitas Timbunan Tinggi Pada Mortar Busa Menggunakan Metode Elemen Hingga Pada Proyek Pembangunan Jalan Baru Batas Kota Singaraja - Mengwitani
Get PDFThe new road construction of Bts. Singaraja City to Mengwitani has now carried out Phase I (SC 5-6) in 2019 there is a handling of high embankments using a geogrid, a slope of 1:2 at a height of ± 20 meters. At the construction site of this road there is limited land for Right Of Way (ROW) due to hilly area conditions. To overcome this problem, it is necessary to design a road embankment construction plan from a material that is safe and light enough, lightweight foam mortar embankment has been found as an alternative method to protect against overload to the ground, with lightweight structural materials and high compressive resistance to support the load. traffic. Based on the current conditions, an analysis of the stability of the light embankment of foam mortar will be carried out as an alternative for handling high embankments with variations of the vertical slope, 1:1, 1:2 and 1:3, an analysis of the stability of the embankment using the Plaxis application. The results of the analysis show that the greater the slope used, the greater the safety factor that occurs. Based on the results of the analysis, the variation of the slope of the upright embankment collapses so that there is no safety facto

3,6-dimethyl ester-α-mangostin Compound Modified from Isolate α-mangostin Garcinia Mangostana Linn
Get PDFIsolate α-mangostin (1) is a phenolic compound derived from oxygenated and prenylated xanthones and major compounds obtained from the fruit peel of G. mangostana Linn., Which is stated to have inhibitory activity against α-glucosidase enzymes, serves to determine the antidiabetic activity resulting in IC50 value of 29,92 µM, is of the nature moderate to positive control (acarbose) with an IC50 value of 4.55 µM. A modified compound of α-mangostin (1) with acetic anhydride obtained by 3,6-di-methyl ester-α-mangostin (2) derivative showed the inhibitory value of α-glucosidase (IC50 13,89 μM), this value is better than the activity inhibition of α-mangostin (1), but not as active as the positive control value of the acarbose compound. The separation process to obtain α-mangostin isolates from the fruit peel of G. mangostana Linn was obtained by maceration method with ethyl acetate solvent, followed by refraction using a vacuum liquid chromatography (KCV) method over silica gel (Merck 60 G) and eluted using eluent (n-hexane: ethyl acetate) with increasing polarity, to produce as much pure crystal (21.66 g), yield (24%). While the structural characterization of the two compounds was carried out using UV-Vis, IR, HRESIMS, 1H-NMR and 13C-NMR spectroscopic methods, the antidiabetic testing was carried out using the α-glucosidase enzyme inhibition method

Religious Populism and Public Sphere in Indonesia
Get PDFReligious populism has strong and profound influence in Indonesia. It challenges the rational foundation of the democratic structure of the Indonesian Politics. This populist political movement utilizes religious language and symbols as their language of political articulation, negotiation, and contestation, which then occupies the real and virtual public sphere of the politics of Indonesia. Therefore, this use of religious language and symbols has placed democratic system in a serious risk. This critical study is intended to investigate the disadvantages of the use of religious language and symbols in the political arena in Indonesia. I will employ Paul Ricour’s thoughts in his writing, The Fragility of Political Language, as a lens of analysis for that phenomenon. Through that analysis I argue that the use of religious language and symbols in political discourse contradicts the provisional character of political language in democratic political settings. I suggest, therefore, the reenactment of the constitutional and rational foundation of democratic structure of Politics in Indonesia is seriously required
