Abstract

Zeolite-X is a potential material for CO2 adsorption. To increase the performance of zeolite-X, kapok fiber was used as a support material. The growth of zeolite-X on the surface of kapok was affected by activation of the surface. This research aims to optimize the immersion time of kapok fiber using NaOH in order to achieve high crystallinity of the zeolite-X. The Zeolite-X supported on kapok fiber was synthesized by the simple hydrothermal method at immersion time variation of 12 to 36 h. XRD results show that zeolite-X on kapok surface has the highest crystallinity at immersion time of 24 h. The topography of kapok surface from AFM indicates that the surface was damaged due to peeling reaction of NaOH. SEM results show that zeolite-X has grown on the kapok surface in considerable amounts. From TGA analysis, it was shown that the thermal stability of zeolite-X supported on kapok surface was up to 300 °C. Adsorption of CO2 measured by gravimetric method shows that CO2 adsorption capacitywas up to 15.097 wt.% at room temperature.

Abstract

Abstrak - Garam merupakan salah satu kebutuhan pelengkap dari kebutuhan pangan dan merupakan sumber elektrolit bagi tubuh manusia. Kelompok usaha garam Tiberias merupakan salah satu kelompok usaha garam yang terletak di Kelurahan Oesapa Barat Kecamatan Kelapa Lima Kota Kupang. Tujuan dari penelitian ini yaitu untuk mengetahui kadar air, natrium klorida (NaCl), iodium, magnesium (Mg) dan kalsium (Ca), pada garam masak tradisional di Kelompok Tiberias, Kelurahan Oesapa Barat, Kota Kupang. Penelitian dilaksanakan pada bulan April-Mei 2021. Penelitian ini menggunakan metode kualitatif dan kuantitatif dengan analisis data menggunakan metode deskriptif komparatif. Untuk pengujian kadar air, natrium klorida (NaCl), iodium, magnesium (Mg) dan kalsium (Ca) dilakukan pada Laboratorium PT. Saraswanti Indo Genetech, Bogor. Hasil penelitian menunjukkan bahwa kadar air memenuhi SNI 3556-2016 dan SNI 4435-2017, kadar NaCl belum memenuhi SNI 3556-2016 tetapi memenuhi SNI 4435-2017 dan tergolong pada garam K2 (garam kualitas sedang), kadar iodium tidak memenuhi SNI 3556-2016, kadar magnesium sebesar 183,71 mg/100 g dan kadar kalsium sebesar 503,70 mg/100 g. Kesimpulannya adalah teknik pembuatan garam masak menggunakan alat tradisonal yaitu garam krosok sebanyak 18 kg, air tawar 100 liter dicampur dengan garam krosok, penyaringan berlangsung selama ±1 jam, pemasakan selama ±6-7 jam, penirisan garam berlangsung selama ±5 jam, dan pengemasan garam kedalam karung berkapasitas 50 kg dan kualitas garam yang diproduksi. Untuk pengujian kadar air: 4,6-4,75%, NaCl: 91,02%, iodium: 8,45mg/kg, magnesium: 183,71mg/100g dan kalsium: 503,70mg/100g. Kata Kunci: Garam, Tradisional, Air, NaCl, Magnesium, Kalsium
