Abstract

Nifedipine is a drug with a small solubility in water, a consequence, in order to obtain the desired drug release, the solubility of nifedipine should be increased by the addition of PVPK-30.This study was aimed to know the effect of HPMC K15M, PVP K-30 on the release of nifedipin, and Avicel PH 102 on the floating lag time of nifedipine floating tablet, and to find out the proportion of each ingredient to produce the optimum formula of nifedipin floating tablet. The study was conducted using Simplex Lattice Design (SLD) with 3 components i.e. HPMC K15M, PVPK-30 andAvicel PH 102 in order to obtain 14 formulas. The optimization parameter consists of absorption tablet, floating lagtime, C360 and DE360. The four parameters were analyzed using Design Expert7.1.3 software to determine the optimum formula. The optimum formula was obtained by determining the desired target for each parameter. The absorption was selected in maximum target, floating lag time was selected in minimum target, C360 targeted at number 54 and DE360 targeted at number 40. HPMC K15M at the highest concentration affected the smallest release of nifedipin, the highest PVP K-30 concentration affected the most of nifedipin release, where as high concentration Avicel PH 102 had a small affected reduce in floating lag time of nifedipin floating tablet. The composition of the optimum formula is as follows: 80mg HPMC K15M, 97mg PVPK-30 and 45mg Avicel PH 102. The results of tablet absorption, C360 and DE360 did not differ significantly; floating lag time gave significantly different results to obtain from software. The release kinetics of all formulas fit order 1, which indicated that the drug release occurred through a diffusion mechanism.

Abstract

There is a diversity of interpretations regarding the Quranic verse on the jilbab. Among these interpretations, some are robust in terms of argumentation, while others appear biased and subjective. This article delves into Quraish Shihab's thoughts on the jilbab verse and critically analyzes them. This research is a type of library research using a descriptive analysis method, which describes the research findings based on a focused problem by critically analyzing them to produce objective results. The approach used is content analysis. The primary sources for this research are Tafsir Al-Mishbah and Jilbab Pakaian Wanita Muslimah. The research findings indicate: First, in Quraish Shihab's perspective, wearing the jilbab is not obligatory; its command is merely a recommendation and applies only during the time of Prophet Muhammad. Scholars also do not unanimously agree on the boundaries of a woman's aurat, and the jilbab sharia is a teaching that takes into account Arab societal traditions, making it not applicable to other nations that do not wear the jilbab. Second, Quraish Shihab's interpretation of the jilbab verse lacks a strong argumentative basis in Islamic studies. The wording of the command in the jilbab verse is still understood as an obligation and cannot be transformed into a mere recommendation because there is no evidence diverting it; scholars have unanimously agreed on the boundaries of a woman's aurat, which extends from the top of the head to the tips of the toes, excluding the face and the palms of the hands; the sharia of the jilbab remains applicable until the end of time, even though it was revealed under specific conditions and in a particular region, as Islam is a universal religion.

Abstract

Dalam dekade terakhir, radikal bebas dapat menyebabkan banyak penyakit, misalnya kanker. Antioksidan merupakan senyawa yang mampu menghambat aktivitas radikal bebas. Indonesia memiliki kekayaan sumber daya alam yang bisa dieksplor aktivitas antioksidannya. Salah satu tumbuhan Indonesia yang potensial yaitu kepundung (Baccaurea racemosa). Bagian daun, batang, buah, kulit buah, dan kulit batang kepundung dilaporkan memiliki aktivitas antioksidan yang tergolong sedang sampai sangat kuat. Namun, aktivitas antioksidan biji kepundung belum pernah dilaporkan. Oleh karena itu, penelitian ini bertujuan untuk mengekplorasi aktivitas antioksidan biji kepundung dan korelasinya dengan kandungan fenolik totalnya. Biji buah kepundung diekstraksi dengan metode maserasi bertingkat diawali dengan pelarut petroleum eter kemudian dilanjutkan dengan kloroform lalu etil asetat. Ekstrak petroleum eter, ekstrak kloroform, dan ekstrak etil asetat biji kepundung dianalisis aktivitas antioksidannya menggunakan metode penangkapan radikal bebas 2,2’-diphenil-1-picrylhydrazil (DPPH). Sementara itu, kandungan fenolik total diuji menggunakan metode Folin-Ciocalteu. Korelasi antara aktivitas antioksidan dan kandungan fenolik total dianalisis menggunakan Person correlation test. Hasil menunjukkan bahwa ekstrak petroleum eter, ekstrak kloroform, dan ekstrak etil asetat secara berurutan memiliki persen penghambatan radikal DPPH sebesar 6,35 ± 0,97 %; 28,84 ± 5,48 %; dan 50,78 ± 1,18 %. Sementara itu, kandungan fenolik total ekstrak petroleum eter, ekstrak kloroform, dan ekstrak etil asetat secara berurutan yaitu 0,10 ± 0,01; 15,12 ± 0,52; dan 30,62 ± 0,87 mg ekuivalen asam galat/ gram ekstrak (mg EAG/g). Senyawa fenolik ekstrak biji kepundung berkorelasi positif dan signifikan dengan aktivitas antioksidannya. Senyawa fenolik berkonstribusi sebesar 98,9% terhadap aktivitas antioksidan biji kepundung. Biji kepundung dapat dikembangkan lebih lanjut sebagai antioksidan alami.
