| Abstrak (Bhs. Indonesia) | Biomulsa lembar mulai banyak dikembangkan dan diaplikasikan dalam pertanian untuk mengurangi penggunaan mulsa plastik yang dapat mencemari lingkungan. Alang-alang dan jerami merupakan bahan dasar potensial untuk pembuatan biomulsa lembar karena ketersediaannya sangat melimpah dan murah. Namun, kajian tentang kalaikan/performansi biomulsa lembar tersebut masih sangat terbatas. Penelitian ini bertujuan untuk: 1) mengukur sifat fisik-mekanik biomulsa lembar berbahan dasar alang-alang dan jerami, dan 2) mengetahui pengaruhnya terhadap penekanan laju evaporasi dan gulma. Biomulsa lembar dibuat dengan bahan dasar jerami (J) dan alang-alang (A), masing-masing dicampur dengan bahan perekat eceng gondok sebanyak 80% (1), 50% (2), 40% (3), dan 10% (4), sehingga diperoleh total 8 kombinasi perlakuan, yaitu J1, J2, J3, J4, A1, A2, A3, dan A4. Performansi biomulsa lembar tersebut dikonfirmasi melalui uji sifat fisik-mekanik, meliputi rendemen, ketebalan, daya serap air, kuat tarik, kuat tekan, dan ketahanan (vilensky), serta uji lapang selama 1 minggu untuk melihat kemampuan penekanan laju evaporasi dan gulma. Data dianalisis dengan F-test/Anova. Hasil penelitian menunjukkan bahwa rendemen dan ketebalan biomulsa lembar tertinggi masing-masing adalah 75,6% (A4) dan 4,01 mm (A4), sedangkan daya serap air tertinggi diperoleh sebesar 6,66 ml/g (A1). Kuat tarik dan kuat tekan tertinggi diperoleh pada A4, masing-masing sebesar 0,083 dan 5,56 kg/cm2. Berdasarkan Uji Vilensky, biomulsa lembar yang dibuat tidak tahan terhadap air lebih dari 1.000 tetes, kecuali J1, J2, A1, dan A2. Secara keseluruhan biomulsa lembar tersebut mampu menekan gulma hingga 100%, namun hanya A4 yang efektif menekan laju evaporasi lebih dari 60%. |

| Abtrak (Bhs. Inggris) | Sheet biomulch has been developed and applied in agriculture recently to reduce the use of plastic mulch that potent to be pollutant to environment. Paddy straw and grass reed are the potential basic materials for sheet biomulch since the materials are available and cheap. However, feasibility/performance study to the sheet biomulch has been yet limited. This study was aimed to: 1) measure physical-mechanical properties of sheet biomulch originated from paddy straw and grass reed and 2) identify the effect of reducing evaporation rate and suppressing weeds. The sheet biomulches were made of paddy straw (J) and grass reed (A), mixed with the water hyacinth-based gluten of 80% (1), 50% (2), 40% (3), and 10% (4), thus totally 8 combined treatments namely J1, J2, J3, J4, A1, A2, A3, and A4 were obtained. Performance of the sheet biomulches were confirmed through the physical-mechanical properties test including yield, thickness, water absorption, tensile strength, compressive strength, and endurance (vilensky), and also the 1 week field evaluation to identify the ability to reduce evaporation rate and suppress weeds. The data were analyzed using F-test/Anova. The results showed that the highest yield and thickness of the sheet biomulch were 75.6 (A4) and 4.01 mm (A4), respectively, while the highest water absorption was 6.66 ml/g (A1). The highest tensile and compressive strength was obtained in A4, namely 0.83 and 5.56 kg/cm2, respectively. According to Vilensky test, the developed sheet biomulches could not stand against water higher than 1,000 drops, except J1, J2, A1, and A2. The overall sheet biomulches were able to suppress weed up to 100%, but only A4 was effective to reduce evaporation rate more than 60%. |
