Abstract

Menurut perspektif hukum Islam, euthanasia merupakan tindakan yang diharamkan. Ada beberapa alasan euthanasia dilarang dalam Islam, yaitu: Pertama, eutanasia merupakan tindakan mendahului takdir Allah swt. Setiap manusia sudah ditentukan ajalnya masing-masing oleh Allah swt. yang pada saatnya tiba tidak akan bisa diajukan atau diundurkan sedikit pun. Kedua, karena euthanasia merupakan bentuk putus asa dari rahmat Allah. Ketiga, eutanasia termasuk pembunuhan yang dilarang oleh Allah swt. Pembunuhan itu termasuk dosa besar. Undang-undang hukum pidana yang berlaku sekarang di Indonesia memuat pasal-pasal yang mengancam dengan hukuman bagi orang yang menghilangkan nyawa orang lain dengan sengaja ataupun karena kurang hati-hati dengan 12 tahun penjara. Seorang dokter bisa dituntut oleh penegak hukum, apabila ia melakukan euthanasia, walaupun atas permintaan pasien dan keluarga yang bersangkutan, karena perbuatan tersebut merupakan perbuatan melawan hukum. Kedokteran Islam menilai praktik eutanasia (pembunuhan dengan belas kasihan) diharamkan, Islam sangat menghargai kehidupan dan tidak memberi hak bagi manusia untuk mencabut nyawa seseorang karena masalah nyawa itu adalah hak dan milik Allah.

Abstract

Magnesol membrane has been prepared by mixing chitosan polymer with magnesol particles via phase inversion method. The optimum compositions of adsorptive membranes were 3% chitosan, 15% DMF and 60% loading adsorbent. The porosity of these membranes was 34,17% and swelling degree was 51,91%. The membrane clean water flux was 224,4 Lm?2h?1 at a transmembrane pressure of 2.5 bar.  The adsorptive membrane possesses an open and interconnected porous structure with a large surface area available for biodiesel purities adsorption. The results showed that after contacting in 60 minutes, numbers of acid value was reduced as 81,12% which is in accordance with value of SNI quality standards. In addition, the soap content adsorbed was 86,74%  as potassium soap and 86,73% as sodium soap. The regenerated membrane can be reused with mantaining the high adsorption capacity. The methanol was better than ethanol to regenerate the magnesol membrane. The Magnesol membrane will be a new alternative method for biodiesel purification.Keywords: biodiesel, membrane adsorption, chitosan, magnesol, acid number, soap

Abstract

Janeng starch (Dioscorea Alata) and rice straws are developed to be used as adsorbents in dry washing method to purify crude biodiesel. In this study, we evaluate the potential of rice straw and janeng starch as natural adsorbents in the purification of biodiesel that replace the role of water in absorbing contaminants from biodiesel. The SEM characterization results show that the starch adsorbent and rice straw has an open and porous surface and is evenly distributed for janeng starch. Both adsorbents, either the janeng starch or rice straw, can be applied for the purification of biodiesel. The quality of biodiesel is influenced by the amount of adsorbents used in biodiesel purification. The effectiveness of the adsorbent is shown by the decrease in free fatty acids, alkali numbers, soap numbers and turbidity levels in biodiesel. The concentration of free fatty acid oil in crude biodiesel before the purification step was 0.769 mg-KOH/g, then decreased to 0.128 mg-KOH/g after the adsorption. This acid value had been very low and met the Indonesian quality national standard for biodiesel spesically 0.50 mg-KOH/g. Either janeng starch or rice straw adsorbent was able to reduce the soap content of potassium oleate to level 53.33 ppm from the initial content of 106.67 ppm. These two natural adsorbents can be the alternative adsorbents in the purification of biodiesel that employs dry washing method.

Abstract

Hematite (Fe2O3) was successfully extracted from the Aceh iron ore mineral by precipitation method with employing sulphuricacid (H2SO4) as chemical agent.  Furthermore, the extracted hematite was modified with sodium metal (K), namely it doped with NaOH of 5% and 10% (w/w), respectively. Based on the characterization results using XRD and SEM- EDS proved that modified catalyst (Na2O/Fe2O3) with their homogeneous size were resulted while the hematite (Fe2O3) particles was dopped withNaOH at its low concentration of (5% wt/wt), however while doping with the higher concentration of NaOH (10% w/w), agglomeration was taken place among the catalyst particles in which decreasing the surface area of the modified catalysts. Finally, the modified catalyst (Na2O/Fe2O3) was successfully applied as an inorganic catalyst on transesterification of coconut oil and methanol (T = 55 ? 60oC, 2 h)for forming methyl esters asbiodiesel compounds.

Abstract

Polyurethane membrane made from Rubber Seed Oil has been produced within this research. Rubber seed oil has the hydroxyl number of  40,33 mg/g  and the iodine number of  154,05 g/g which can be used as resource clusters; -OH, in order to make polyurethane. Rubber seed oil can react with hexamethylene-1.6-diisocyanate (HDMI) as another resource cluster, which is -NCO. The production of polyurethane membrane is done by variating the composition of rubber seed oil and HDMI, with the variations of 5:1; 5:3; 5:4; 5:5 dan 5:7 (v/w) and the polymrization temperature of 90-100°C and the curring temperature of  165-170°C. The optimal polyurethane membrane is produced on the composition of 5:4 v/w  which is homogenous, dry, quite elastic and is yellowish brown in colour. The IR results showed that there were urethan bonds formed (N-H on  ? = 3300-3400 cm-1) and the TGA results from polyurethane membrane showed that there were two decompositions on 394,5oC dan 458,6oC.

Abstract

Silica particles had been successfully separated and extracted from rice husk by using solution of sodium hydroxides (NaOH) as solvent and were characterized with SEM-EDX. The data SEM-EDX showed that the extracted component of the rice husk contained 79,55% (w/w) of silica as the primary component. In order to understand the adsorption capacity of silica in removing free fatty acids (FFA) which were recognized as the contaminants in biodiesel., the profile of time dependence and silica amount in the adsorption process had been investigated in this study. The results indicated that the adsorption process showed optimum condition at 30 minutes with the free fatty acids (about 90,64%) of adsorption). Moreover, the adsorption capacity of silica to those impurities contaminated in biodiesel was proportional to the amount of adsorbent used in the experiment. Finally, biodiesel with less FFA was produced, and the FFA residues remained in the biodiesel were 0,58 mg/g.

Abstract

PTAI existence in this globalization era demanded an active role in developing the Islamic studies. Likewise develop the social sciences, humanities independently as part of Islamic studies. PTAI as Islamic educational institutions must develop Islamic education development strategy that refers to the Islamic epistemology. Epistemological occupies a strategic position in the development of Islamic education in PTAI, because he talked about how to get the right knowledge. The strategy of development of Islamic education in PTAI, among others, are (1) Reconstruction of Islamic Studies at PTAI.   (2) Developing the Islamic sciences. (3) The use of science to aid the study of Islam.  (4) Increased research faculty. (5) Improved quality standards PTAI, (6) Modernization PTAI. (7) Strengthening of Islamic education in PTAI epistemology. The effort to develop Islamic education in PTAI namely a) PTAI align themselves with the demands of modern, b) PTAI need to recreate a new paradigm of Islamic education, c) PTAI need to reorient education vision and mission, goals, management, organizational structure, materials and teaching methods, and culture community, d) PTAI should be orientation on improving the quality of faculty and students, e) development of Islamic education is directed through research, f) paradigm PTAI forward directed at cultural paradigm rather than natural, g) PTAI able to translate normative religion into science theoretical.
