Abstract

Tandan kosong kelapa sawit (TKKS) merupakan limbah padat utama dari industri pengolahan kelapa sawit yang jumlahnya melimpah namun belum dimanfaatkan secara optimal. Penelitian ini bertujuan untuk menganalisis efektivitas pupuk daun berbasis bio-grafena yang berasal dari TKKS dibandingkan dengan pupuk NPK terhadap pertumbuhan tanaman tomat. Proses penelitian melibatkan beberapa tahap, yaitu pembuatan prekursor bio-grafena oksida (bio-GO) melalui pirolisis TKKS, karbonisasi, dan karakterisasi yang mencakup morfologi, fasa, ke kristalan, dan ukuran partikel. Empat variasi pupuk daun (NPK, NPK+biochar, NPK+grafena, dan grafena) diuji pada tanaman tomat untuk melihat pengaruhnya terhadap tinggi, jumlah daun, bunga, dan buah. Hasil penelitian menunjukkan bahwa pupuk variasi 1 memberikan hasil pertumbuhan terbaik, dengan tinggi tanaman mencapai 145 cm, 292 helai daun, 23 bunga mekar dan 48 kuncup, serta 8 buah besar dan 14 buah kecil. Kemudian, berturut-turut variasi pertumbuhan paling baik setelah variasi 1 yaitu variasi 2, 3, dan variasi 4. Pupuk variasi 1 memberikan dampak paling signifikan terhadap pertumbuhan hal ini karena komposisi NPK yang lebih banyak dibandingkan pupuk variasi lain. Meskipun pupuk variasi 2, 3, dan 4 tidak mengandung NPK sebanyak variasi 1, ketiganya tetap menunjukkan hasil pertumbuhan yang baik, yang mendukung potensi pupuk bio-grafena sebagai alternatif organik yang ramah lingkungan. Penelitian ini menegaskan bahwa pupuk daun berbasis bio-grafena dari limbah TKKS dapat menjadi solusi pertanian berkelanjutan yang efektif sekaligus mengurangi ketergantungan pada pupuk kimia.

Empty palm fruit bunches (EPFB) are the main solid waste product of the palm oil processing industry, which is abundant but has not been optimally utilized. This study aims to analyze the effectiveness of bio-graphene-based foliar fertilizer derived from TKKS compared to NPK fertilizer on tomato plant growth. The research process involves several stages, including the production of bio-graphene oxide (bio-GO) precursors through TKKS pyrolysis, carbonization, and characterization, which includes morphology, phase, crystallinity, and particle size. Four variations of leaf fertilizer (NPK, NPK+biochar, NPK+graphene, and graphene) were tested on tomato plants to assess their effects on plant height, number of leaves, flowers, and fruits. The results showed that fertilizer variation 1 yielded the best growth, with plant height reaching 145 cm, 292 leaves, 23 blooming flowers, and 48 buds, as well as 8 large fruits and 14 small fruits. Following variation 1, the next best growth variations were 2, 3, and 4. Fertilizer variation 1 had the most significant impact on growth, likely due to its higher NPK composition compared to other variations. Although Variations 2, 3, and 4 did not contain as much NPK as Variation 1, all three still showed good growth results, supporting the potential of bio-graphene fertilizer as an environmentally friendly organic alternative. This study confirms that bio-graphene-based leaf fertilizer from TKKS waste can be an effective solution for sustainable agriculture while reducing dependence on chemical fertilizers.
