Abstract

Jagung merupakan komoditi unggulan di Desa Bangunsari, Pesawaran, namun hasil panen menyisakan limbah biomassa tongkol jagung. Selama ini limbah tongkol jagung hanya dibuang dan dibakar, sehingga menimbulkan masalah polusi, efek rumah kaca dan pemanasan global. Pemanfaatan limbah tongkol jagung sebagai bahan baku biochar dapat menjadi solusi yang menjanjikan. Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk memperkenalkan manfaat penting biochar sebagai pembenah tanah kepada petani di Desa Bangunsari, membangun tungku produksi biochar, dan mempraktikkan cara membuat biochar dari tongkol jagung. Metode pengabdian menggunakan PLA (Participatory Learning and Action) dengan melibatkan beberapa petani yang dilatih dalam pembuatan biochar. Dari kegiatan PKM ini telah dibangun satu tungku produksi biochar dari batu bata dan tanah liat yang mampu memproses bahan baku berupa limbah tongkol jagung dengan kapasitas proses 35 meter kubik. Petani yang terlibat dalam kegiatan PKM ini mengerti proses pembuatan biochar menggunakan tungku tanah liat

Abstract

Torrefaction has been well known to improve the properties of various biomass pellets. However, the study on torrefaction of andong bamboo pellet is still limited. This study aimed to evaluate the changes in the physical and mechanical properties of Andong bamboo (Gigantochloa pseudoarundinaceae) pellets resulting from torrefaction.  The pellets were torrefied at 200°C, 240°C, and 280°C using an electric furnace for 50 min.  The physical properties analyzed were color, moisture content, density, water adsorption, and resistance to water immersion.  A compressive strength test examined the mechanical property.  The results showed that the color of bamboo pellets torrefied at 200°C, 240°C, and 280°C were changed, showing overall color change (∆E*) values of more than 12. The lightness (L*) of the pellet remarkably decreased with the increase of torrefaction temperature. In other words, the pellet became darker with increasing temperature. The yellow/blue chromaticity (b*) was also decreased with increasing the torrefaction temperature. However, the red/green chromaticity (a*) increased at 200℃ but decreased at 240℃ and 280℃. Moisture content and pellet density decreased with increasing torrefaction temperature.  The pellets’ water adsorption decreased as the torrefaction temperatures increased at 200℃, 240℃, and 280℃.  The results also showed that the torrefied pellets were more resistant to water immersion than the control pellet as they could maintain their original form even after 24 h immersion test.  The compressive strength decreased as increasing the temperature. The torrefaction temperature affected and improved the properties of Andong bamboo pellets.
