Abstract

One of the application of zeolite as a multi-function mineral is the use as catalyst. Investigation to utilize Indonesian natural zeolite as a catalyst will increase the added value and gives a chance to reduce the dependency of imported catalyst. One of the main property, which allow zeolite to be used as a catalyst, is a high silica-alumina ratio, where Si/Al >10. As a preminalry stage to form a catalyst zeolite, research has been carried out to increase the Si/Al ratio of natural mordenite from Cikalong, Tasikmalaya. The method applied is dealumination process, which is followed by calcinations and ion exchange. This process is expected to modify the Na-zeolite from natural mordenit to be a NH4-zeolite which can be transformed to a catalyst zeolite. Dealumination process is carried out using HNO3, with variable concentration and time at temperature of 85°C. Thereafter, zeolite is calcined at 700°C and is followed ion exchange process using NH4NO3. The current stage of research has been succeeded to increase the Si/Al ratio of natural mordenite from Si/Al @ 5 to Si/Al > 10. The process condition applied is dealumination with 8N HNO3 for 24 hours at 85°°C and is followed by calcinations at 700°C for 2 hours. Ion exchange is proceeded with 5% NH4NO3 for 2 hours and is followed by another calcinations at 400°C for 2 hours.

Abstract

Latar Belakang: Anak muda merupakan salah satu kelompok rentan anemia sebab hadapi perkembangan sangat pesat diiringi kegiatan- kegiatan jasmani serta berolahraga pula pada keadaan puncaknya. Berartinya bimbingan yang didapatkan anak muda terpaut penangkalan anemia supaya siswi bisa mengidentifikasi ciri serta indikasi anemia dan penangkalan supaya bisa ditangani secara dini, penangkalan anemia bisa dicoba dengan pola style hidup serta jajanan sehat untuk siswa.Metode: Desain dalam riset ini memakai Quasi eksperimen dengan memakai pendekatan one group pretest posttest design.Hasil: hasil uji statistik dengan Uji Paired Samples Test nilai P value yang dihasilkan sebesar 0, 000<0,05, serta nilai P value yang dihasilkan sebesar 0, 000<0,05. Hasil: Dari hasil uji chi- square didapatkan p=0,002 (p value < 0,05.Kesimpulan: Ada pengaruh yang signifikan terhadap pengetahuan serta perilaku anak muda tentang mengkonsumsi tablet tambah darah di Sekolah Menengah Kejuruan(SMK) kesehatan bhakti pertiwi indonesia cicurug sehabis diberikannya pembelajaran pengaruh pembelajaran kesehatan terhadap pengetahuan serta perilaku.
