Abstract

Prayer is one of the five important pillars of Islam. This is an obligation that must be fulfilled by humans as a form of worship to Allah. Prayer is not only a religious ritual, but also a way to achieve the goal of perfect worship, by fulfilling the conditions, harmony, and sunnah, and avoiding anything that could cancel it. Even though prayer is not an obligation for young children such as those who have not reached puberty, parents have the responsibility to introduce prayer and other forms of worship from an early age. This research aims to explore the effectiveness of an educational program that focuses on teaching reading and prayer movements for children at TPQ AL – Faqih Gadungan, Puncu, Kediri. The method used in this research is PAR (Participatory Action Research). The research results showed a significant increase in children's prayer abilities because they felt happy and interested in praying both at TPQ and at home. This program also encourages them to get used to praying with full humility and tu'maninah, and to be able to recite the prayer readings fluently and correctly.

Abstract

In the wastewater treatment of leather tanning processes, commercial activated carbon from palm shells is usually used as an adsorbent. Therefore, a study is needed to evaluate the effectiveness of activated carbon that has been repeatedly regenerated and used as a total chromium adsorbent medium in wastewater. This study aims to examine the leaching process that uses acids and bases to analyze the adsorption and regeneration processes of activated carbon. Adsorption time variations of 30 minutes, 60 minutes, 90 minutes, and 120 minutes were used to evaluate how activated carbon interacts with wastewater. Then, the effluent was analyzed by Atomic Absorption Spectrophotometry (AAS) to determine the amount of total chromium remaining in the sample. The activated carbon which had been used as an adsorbent was contacted with 0.1 M H2S04 solution for 4 hours and stirred at 400 rpm using a magnetic stirrer to regenerate the surface of the activated carbon. It is neutralized with an alkaline solution. The Freundlich model is used to determine the value of the adsorption equilibrium constant. After testing 5 times, commercial activated carbon can still be used effectively as a adsorbent medium for total chromium (total Cr) repeatedly. Optimum adsorption contact time was 90 minutes. The optimum absorption efficiency during the fifth stage of the adsorption process was 43.93%.
