Perkembangan industri tekstil di Indonesia menyebabkan peningkatan dalam jumlah limbah yang dihasilkan. Limbah tekstil sebagian besar terdiri dari zat warna yang digunakan untuk proses pencelupan d…
Currently, one crucial issue in the development of rechargeable batteries is to find an alternative battery system to replace lithium-ion battery (LIB) in order to solve the issue of safety and sca…
Material graphene pertama kali ditemukan oleh ilmuwan asal Rusia, Andre Geim dan Konstantin Novoselov pada tahun 2004. Graphene diperoleh dengan cara pengelupasan grafit secara mekanik dengan mengg…
Carbon nano-spheres (CNSs) were synthesized from commercial activated carbons and cooking oil as carbon precursors using simple pyrolytic process and then were used as anode materials of lithium se…
Carbon Nanospheres (CNSs) have been synthesized by thermal pyrolysis method. A mixture of Fe-catalyst supported activated carbons and palm oil was used in the furnace to produce CNSs. Prior to the …
Salacca peel-based porous carbon (SPPC) with high surface area (1945 m2 g−1) and large specific pore volume (1.68 cm3 g−1) was prepared by pre-carbonization and K2CO3 activation method. Based o…
Sodium (Na) ion battery (NIBs) are considered as one of the most prospective battery system to substitute lithium ion batteries (LIBs) especially for stationary applications. In this study, rambuta…
In this work, waste tea-based porous carbons were prepared by hydrothermal carbonization and then followed by the chemical activation using KOH and ZnCl2. As-prepared porous carbons were then used…
Pewarna rambut saat ini sudah menjadi bagian dari gaya hidup. Sangat disayangkan bahwa pewarna rambut yang beredar di pasar adalah pewarna rambut sintetis yang memiliki dampak negatif bagi kesehata…
Petai cina (Leucena leucocephala) merupakan tanaman yang tumbuh subur di Indonesia. Selama ini, petai cina hanya dimanfaatkan sebagai bahan pangan. Padahal biji petai cina mengandung protein teruta…
