The purpose of this research is to study the effectiveness of smoke clearing with adsorbents measured in situ using the photoelectric type smoke detection system. The influence of the type, size and the mass of the adsorbents was evaluated against the smoke clearing process. Adsorbent types studied were commercial activated carbon, ZnCl2-activated carbon, and activated natural zeolite, with the size of 0.6-1.0 ?m, 1.0 to 2.0 ?m, 53-106 ?m, and 106-212 ?m, and the mass of 1, 3, and 5g. The smoke was generated by burning tissue paper using an electrical soldering apparatus. The adsorbent was dispersed using a pressurized nitrogen system. The results showed that in comparison with no adsorbent, the activated carbon and natural zeolite were more effective for clearing the smoke. The order of clearing effectiveness was best achieved by commercial activated carbon, ZnCl2-activated carbon and activated natural zeolite, respectively. Particle size of 53 micron provided the most effective performance. The more mass of adsorbent dispersed, the faster the clearing process. Clearing process at the top of the column was faster than that at the bottom. The best t10 value obtained for the top, middle and bottom column were 4, 4.6, and 7.7 minutes, respectively. In addition, the average adsorption of carbon monoxide was less than 15%.

Penyimpanan energi panas sistem adsorpsi memiliki reaksi bolak-balik dimana terjadi reaksi eksotermik ketika proses adsorpsi dan reaksi endotermik ketika proses desorpsi. Sistem ini memungkinkan penyimpanan panas untuk sumber energi yang tidak kontinu seperti sumber energi matahari dan sisa panas buang industri. Ketika proses adsorpsi berlangsung, panas dilepaskan dari adsorben dan dihitung sebagai jumlah panas adsorpsi yang dapat disimpan. Zeolite alam merupakan adsorben dengan potensi yang cukup besar mengingat panas adsorpsi yang cukup tinggi, karakteristiknya yang berporos, luas permukaan yang besar, dan kemampuannya untuk meng-adsorp molekul yang sangat kecil seperti air. Selain itu, zeolite alam merupakan bahan alami yang potensi sumber dayanya cukup besar di Indonesia. Dalam penelitian ini, dilakukan analisis terhadap kemampuan penyimpanan panas sistem adsorpsi menggunakan pasangan zeolite alam-air sebagai adsorben-adsorbat untuk temperature pemanasan 160°C dengan variasi temperature adsorber dan evaporator (30°C, 35°C, 40°C). Didapatkan bahwa densitas energi paling besar didapatkan pada temperature 40°C sebesar 69.65 kWh/m³. Terlebih lagi, zeolite alam dapat terus dikembangkan untuk meningkatkan kemampuannya mengadsorp air dan menyimpan panas lebih banyak.

ABSTRACT
Adsorption thermal energy storage has reversible reaction which are exothermic in adsorption reaction and endothermic in desorption reaction. This system is a promising technology for the storage of intermittent energy, such as solar power and industrial waste heat. During the adsorption reaction, heats are released and calculated as the amount of energy that can be stored. Natural zeolite is a potential adsorbent due to its high heat of adsorption, porous structure, high surface area and ability to adsorb small molecule such as water. Moreover, Indonesia has quite a lot of zeolite resourches. In this research, we analyze the storage performance of adsorption thermal energy storage using natural zeolite-water as a pair for charging temperature of 160°C at different evaporator and adsorber temperature ranges (30°C, 35°C, 40°C). As the result, the highest energy density reached at temperature 40°C with 69.65 kWh/m³. Furthermore, natural zeolite can be developed as it can be modified to enhance its ability to adsorb water.

Telah dilakukan modifikasi zeolit alam dari Bayat-Klaten untuk material alternatif pengolahan limbah Thorium di Instalasi Pengolahan Limbah Radioaktif Batan. Zeolit alam yang umumnya merupakan material dengan ukuran mikropori dimodifikasi dengan menggabungkan dua metode yang biasa dilakukan untuk mengubah ukuran mikropori zeolit menjadi zeolit hierarki, yaitu dealuminasi dan desilikasi. Proses dealuminasi diharapkan dapat meningkatkan rasio Si:Al sehingga terjadi proses pengaturan ulang dalam kerangka zeolit, kemudian dilakukan proses desilikasi yang bertujuan untuk melarutkan sebagian Si dalam kerangka zeolit dan mengarahkan pembentukan mesopori dalam zeolit sehingga dapat meningkatkan kapasitas adsorpsi zeolit alam Bayat. Karakterisasi dilakukan dengan menggunakan XRD, FTIR, BET, SEM-EDS, dan AAS. Pola difraksi XRD untuk raw zeolite, zeolit pre-treatment, NaZ, ZA1, ZA2, ZA2B, ZB1 menunjukkan bahwa proses modifikasi ini tidak mengubah struktur kristal zeolit. Dalam penelitian ini setelah proses dealuminasi terjadi peningkatan rasio Si/Al dari sebelumnya 6,688 untuk NaZ menjadi 11,401 untuk zeolit alam termodifikasi dengan metode tandem acid-base treatments (ZA2B). Luas permukaan zeolit juga mengalami peningkatan, dari sebelumnya 125,4m2/g (NaZ) menjadi 216,8m2/g (ZA2B). Zeolit yang berhasil dimodifikasi memiliki sisi aktif yang cukup besar yang dapat berperan menjadi adsorben limbah Th4+ yang lebih baik daripada zeolit tanpa modifikasi. Terlihat dari data UV-Visibel larutan Th4+ yang teradsorpsi dalam zeolit alam termodifikasi adalah ca. 4,2 mg/g pada waktu 120 menit sementara pada waktu yang sama zeolit tanpa modifikasi hanya mengadsorpsi Th4+ sebesar ca. 3,92 mg/g. Adsorpsi Th(IV) oleh zeolit alam dari Bayat ini mengikuti isotherm adsorpsi Freundlich dengan kapasitas adsorpsi untuk NaZ dan ZA2B sebesar 909 mg/g dan 2000 mg/g.
