Abstract
Pencemaran mikroplastik, khususnya polistiren termodifikasi amina (PS–NH₂),
menimbulkan ancaman serius terhadap ekosistem perairan. Adsorpsi menjadi metode yang
efektif untuk penghilangan mikroplastik karena efisiensi tinggi, proses sederhana, dan
memungkinkan pemanfaatan adsorben berbasis biomassa. Adsorben berbasis biomassa seperti
biochar dan karbon aktif telah banyak digunakan, namun masih memiliki keterbatasan dalam
biaya dan kondisi sintesis. Proyek akhir ini menyintesis dan mengkarakterisasi komposit
Hidrochar Teraktivasi/Zeolit-A (AHCZ) sebagai adsorben alternatif dalam sistem kolom
kontinu. AHCZ disintesis melalui karbonisasi hidrotermal serbuk kayu yang diaktivasi
menggunakan KOH, kemudian dikombinasikan dengan zeolit-A hasil sintesis dari kaolin.
Komposit yang dihasilkan akan dikarakterisasi menggunakan FTIR, XRD, SEM, BET, dan
Potensial Zeta guna mengevaluasi struktur dan sifat permukaannya. Selanjutnya, kemampuan
adsorpsi komposit AHCZ terhadap mikroplastik polistiren termodifikasi amina akan diuji pada
variasi pH 4, 6, dan 8 untuk menentukan efisiensi penghilangan dan kapasitas adsorpsinya.

Microplastic pollution, particularly amine-modified polystyrene (PS–NH₂), poses a
serious threat to aquatic ecosystems. Adsorption is considered an effective method for
microplastic removal due to its high efficiency, simple process, and the potential use of
biomass-based adsorbents. While biomass-derived adsorbents such as biochar and activated
carbon have been widely used, they still face limitations in terms of cost and synthesis
conditions. This final project aims to synthesize and characterize a Hydrothermally Activated
Carbon/Zeolite-A composite (AHCZ) as an alternative adsorbent in a continuous column
system. AHCZ is synthesized via hydrothermal carbonization of wood powder activated with
KOH, followed by combination with Zeolite-A synthesized from kaolin. The resulting
composite will be characterized using FTIR, XRD, SEM, BET, and Zeta Potential analysis to
evaluate its structure and surface properties. Furthermore, the adsorption performance of AHCZ
toward amine-modified polystyrene microplastics will be tested at pH variations of 4, 6, and 8
to determine its removal efficiency and adsorption capacity.
