Abstract

Economic and financial issues such as trade (tijarah), rent (ijarah), mortgage (rahn), accounts payable (mudayanah), wages to pay (ujrah) and others related to the basic norms of economic transactions are arranged all in Islam . Allah has reduced sustenance to this world to be used by humans in a way that has been legalized by Allah SWT and is clean of all acts that contain usury. Usury is an additional requirement in a business transaction without the existence of iwadh (equivalent) which is justified by the shari'ah for the addition. Broadly speaking, usury is classified into two; usury of debt and usury debt buying and selling. Usury debt accounts are divided into two, namely; usury qiradh and usury jahiliyah, while usury selling and buying is also divided into two, namely usury fadhal and riba nasi'ah. The rules relating to usury are also widely discussed by the jurists in their books. KHES is the actual form of Islamic law in Indonesia related to Islamic economic activities. So that with the presence of KHES, economic business actors carried out according to shari'ah principles if a dispute occurs, it can be resolved with this KHES reference. KHES has been used as a guideline that replaces Islamic law, namely the Qur'an and hadith. KHES is a syari'ah principle guideline source for Judges in the Religious Court and also for the Syari'ah Arbitration Agency in terms of resolving sharia economic disputes. The problem is that none of the KHES articles deal with usury. The word "usury" is only a few that can be found in this book of KHES. This is due, among others; First, KHES discusses the contracts in mu'amalah. While usury is not a contract. Second, KHES adopts some of the books of Majallah al Ahkam al ‘Adliyyah of the Ottoman Turks so also there is no discussion regarding usury or interest. Third, avoiding usury is the principle of transactions / contracts in the Shari'ah. The position of usury is parallel with gharar, maisir and dharar which must also be avoided. Fourth, that in the treasury of Islamic law or fiqh it has been discussed / discussed in depth and wide, so that it is felt that there is no need to be raised (specifically discussed) in KHES.

Abstract

Kemampuan chitosan untuk mengikat besi dapat diketahui dengan cara mengukur kadar ferritin serum dan deposit besi jantung pada tikus putih wistar (Rattus norvegicus) jantan model iron overload. Metode yang digunakan pada penelitian ini adalah eksperimen laboratorium in vivo. Tiga puluh (30) ekor  tikus wistar jantan dibagi menjadi 6 kelompok, yaitu kelompok normal (N) diberi makanan standar dan tanpa perlakuan tertentu, kelompok control negative (K-) diberi makanan standar dan diinjeksikan iron sucrose 75 mg/KgBB selama lima minggu (3x seminggu) secara intraperitoneal. Kelompok perlakuan terdiri dari P1, P2, P3 diinjeksikan iron sucrose 75mg/kgBB selama lima minggu (3x seminggu) serta diberikan tambahan perlakuan yang berbeda. Selain diberikan makanan standar, kelompok P1 diberikan chitosan secara oral 16 mg/KgBB/hari, kelompok P2 diberikan chitosan secara oral 32 mg/KgBB/hari, sedangkan kelompok P3 diberikan chitosan oral 64 mg/KgBB/hari. Kelompok control positif (K+) pada penelitian ini diinjeksi iron sucrose dan diberikan deferiprone 75mg/KgBB/hari secara oral. Hasilnya menunjukkan bahwa pemberian chitosan 16mg/KgBB/hari yang diberikan secara oral tidak memiliki perbedaan secara signifikan (p>0,05) dari pemberian deferiprone oral dalam menurunkan kadar ferritin serum dan deposit besi jantung.
