Abstract

Telah dilakukan sintesis cetane improver berbahan baku biodiesel yang berasal dari minyak Jarak pagar. Sintesis dilakukan dengan cara nitrasi biodiesel menggunakan campuran pereaksi asam nitrat dan asam sulfat. Proses nitrasi dilakukan selama 4 jam pada temperatur 10-20 oC. Produk hasil nitrasi dikarakterisasi gugus fungsi, flash point dan angka setana. Selanjutnya aditif hasil nitrasi juga dikarakterisasi menggunakan mesin diesel satu silinder untuk menentukan efisiensi termal, BSFC (Brake Spesific Fuel Consumtion), dan nilai smoke.Berdasarkan hasil analisis dengan FTIR diketahui bahwa produk hasil nitrasi mengandung gugus nitro dan nitrat. Selanjutnya berdasarkan hasil pengujian pada mesin diesel secara umum dapat disimpulkan bahwa pada putaran 1200 rpm unjuk kerja mesin (efisiensi termal, BSFC, dan nilai smoke) dari formulasi S0,25% s/d S1,25% tidak lebih baik dibandingkan dengan Solar. Hal ini terjadi pada hampir semua variasi waktu injeksi. Sedangkan pada kecepatan putaran 2200 rpm unjuk kerja formulasi S0,25% s/d S1,25% relatif lebih baik jika dibandingkan dengan solar saja, terutama pada penggunaan aditif dengan konsentrasi sebesar 0,50% (v/v). Penambahan aditif sebanyak 0,10 % dan 0,50% (v/v) tidak merubah nilai flash point, sementara pada nilai angka setana terjadi peningkatan dari 46,3 menjadi 47,1 dan 48,5. Melalui uji aditif secara road test dapat diketahui bahwa penambahan aditif pada bahan bakar solar mampu memberikan penghematan pada penggunaan minyak Solar sebesar 10,4%.Kata kunci : cetane improver, minyak jarak pagar, aditif, minyak diesel

Abstract

The Qur’ân was revealed with justice and equality for human beings regardless of their sex, race, social class and ethnicity, as cardinal principles and intrinsic values in Islamic sharî‘a. If this is the case, modern Muslim society with Islamic law is necessarily of equality and justice. However, their family laws which are grounded on assumptions of past centuries and have little bearing on contemporary realities have not reflected gender relations. Inequality that occurs within the context of Muslim family laws is one of the subtle but most pervasive areas of discrimination against women. It has resulted in a different set of dynamics that help create new demands in favor of change of laws. This study explores the reform strategy through legal mobilization in the Muslim family laws around the world. The findings of the study reveal that the substantive and pluralistic legal mobilization is important to Muslims, and the reinterpretation and renewal of laws have been mobilizing debates among both proponents and opponents, framed by orientations to the modernists who advocate reinterpretation of the original sources and the traditionalists who insist on literal adherence to the received doctrinal corpus.

Abstract

Kahayan River is known to be polluted by mercury due to the gold mining activities which use the mercury in the amalgamation (gold purifying) process. The water and fish in this river are consumed by most of the community live in the river basin. The fish consumed by Central Kalimantan people generally come from Kahayan River. Catfish (Pangasius pangasius) is one of the fish which is often consumed by Central Borneo people. They like the fish because of its delicious taste and its fat flesh. Besides, the fish bones are quite big and do not reach its body flesh. Generally, the yellowtail catfish is also raised by the local citizen inside baskets called karamba along the Kahayan watershed. The purposes of this research are to know: 1) the connection between the concentration of mercury along the Kahayan watershed and the mercury bioaccumulation contained in the catfish’s gill, liver, kidney, and muscles, 2) the catfish’s morphological changes related to the mercury bioaccumulation, and 3) the catfish’s cytological changes related to the mercury bioaccumulation. The results of the research are 1) there is connection between the mercury concentration along the Kahayan watershed and the mercury bioaccumulation contained in the catfish’s gill, liver, and muscles or Ho acceptance, 2) the morphological changes in the fish’s organs are: (a)the gill are experiencing colour changes from red with no spot into pink with spots, (b) the  catfish’s liver are experiencing colour changes from brownish into dark red, and shape changes from compact and not wrinkled into a little bit wrinkled, (c) the fish’s kidney are experiencing colour changes from red into dark brownish red, and shape changes from oval into wrinkled, (d) the fish’s muscles are not experiencing morphological changes either the colour or the shape, there are only some spots in the middle part of the muscle, 3) the cytological changes in the organs cells of the catfish are: (a)the changes in the gill’s cells are in the form of lamella edge swelling, lamella epithelium  cell spreading, and nucleus disappearing; these indicate that there is necrosis in the gill’s cells; (b) the necrosis in the heart cells are marked with the cells colour absorption as the consequence of cells permeability declining and oedema (cell swelling); (c) the necrosis in the kidney cells are marked with the cells colour absorption as the consequence of cells permeability declining and oedema (cell swelling); (d) the cytological changes in the muscles cells of the catfish are not clearly seen, but the blood smear of the sample fish from the villages whose river water indicated to be polluted by mercury like Tumbang Anjir village is having necrosis, indicated by a strong colour absorption as the consequence of cells permeability decliningFrom the research results, it can be concluded that the mercury bioaccumulation in the Kahayan watershed related to the catfish’s morphological and cytological changes is as the result of the toxic nature of mercuryand there is direct connection between the mercury concentration along the Kahayan watershed and the mercury bioaccumulation inside the catfish’s body. Keywords: bioaccumulation, catfish, cytological change, mercury, morphological change
