Penelitian ini bertujuan untuk memanfaatkan limbah kulit kayu kersen (Muntingia Calabura) sebagai penguat komposit matriks polimer yang ramah lingkungan. Serat kulit kayu diekstraksi dan diberi perlakuan alkalisasi dengan larutan NaOH 9% untuk meningkatkan ikatan antar muka serat dan matriks sehingga memberi peningkatkan sifat mekanis komposit. Komposit difabrikasi dengan metode hand lay-upd engan fraksi volume serat 10%, 20%, 30%, dan 40%, kemudian diuji densitas, kekuatan tarik, dan ketangguhan impak. Hasil menunjukkan bahwa peningkatan fraksi serat hingga 40% menurunkan densitas komposit dari 1,208 g/cm³ menjadi 1,173 g/cm³ dan meningkatkan kekuatan tarik, modulus elastisitas, regangan patah, serta energi impak. Temuan ini menunjukkan bahwa limbah kulit kayu kersen dapat menjadi bahan penguat komposit yang ramah lingkungan sehingga dapat memberi kontribusi terhadap pengurangan limbah tidak terurai.
