ABSTRAK
Seiring dengan perkembangan zaman non-plastik, kebutuhan akan teknologi ramah lingkungan menjadi perhatian penting. Inovasi berkelanjutan terus mengalami perkembangan, khususnya dengan meningkatnya pemanfaatan nanoselulosa yang berasal dari serat alami. Shorgum adalah tanaman yang secara fisiologis menarik karena ketahanannya terhadap lingkungan yang panas dan kering. Meskipun demikian, belum ada penelitian mengenai isolasi...

ABSTRACT
Dalam proses pengecoran aluminium, suhu leleh yang tinggi dapat meningkatkan kelarutan gas hidrogen dalam logam cair, oleh karena itu pembentukan porositas gas selama pemadatan aluminium tidak dapat dihindari dan menyebabkan kelemahan utama pada sifat mekanik. Metode yang paling umum untuk mengurangi porositas gas dalam produk casting adalah degassing. Dalam studi...

The definition of the physical and mechanical properties of sugarcane trash pellets were necessary for the design considerations relating to storage, handling and processing equipment. The mixing ratios of ground sugarcane trash:cassava starch:water content (1.0:0.25:0.85 and 1.0:0.25:1.40 by weight) and pelleting speeds (100, 120, 140, and 160 rpm) were considered...

Pohon memiliki kerentanan tumbang terutama di musim tertentu. Seperti pohon Sengon (P.Falcataria) di lingkungan kampus Universitas Indonesia yang sangat rentan tumbang. Kayu dibagi menjadi 2 kategori berdasarkan kandungan air di dalamnya, yaitu kayu segar (Green Wood) dan kayu kering (Dried Wood). Kayu segar (Green Wood) sendiri diartikan sebagai kayu yang...
