There were two main stages in this research: need analysis and prototype design. Need analysis was began with interviewing colleague, analyzing syllabus and lesson plans, analyzing students’ characteristics, analyzing lesson plan literature, self evaluation and metacognition. Prototype design referred to need analysis. Three experts recommended that lesson plans and self evaluation were valid both in terms content and construct.</em>

Among those problems are: drug abuse, drunks, students fights, free sex, and lack of religious practices. The above mentioned approach is believed to be able to solve the problems by encouraging the teenagers to recite the Holy Qoran, to perform late night prayer (qiyamul lail), to do fasting (compulsory and optional as well), to pray and to have self evaluation (muhasabah) more.</em></p><strong>Kata kunci :<span class="Apple-converted-space"> </span></strong>psikoterapi sufistik, menangani masalah agama, dan moral remaja</div>

Limestone was converted in to PCC by using recarbonation method through calcinations, hydration and carbonation processes.

Based on the analysis of physical properties, the size of particle PCC resulted on temperature 1100<span class="Apple-converted-space"> </span><sup>0</sup>C with the surface area 30,96 μm<sup>2</sup>/g was smaller than one on 800<span class="Apple-converted-space"> </span><sup>0</sup>C, 900<span class="Apple-converted-space"> </span><sup>0</sup>C, 1000<span class="Apple-converted-space"> </span><sup>0</sup>C And the percentage of its optical properties namely brithness was 94,9% and whiteness was 91,1 %.
