Abstract

The results of this study are the factors of landslides there are many cracks in the ground, normal faults, shear faults and slope of the soil surface. The higher the slope of the land surface, the more potential for landslides. Results of XRF Waru 1 Si 58.3%, Waru 2 Ca 71.37%, Waru 3 Si 43.3%. The results of XRD Waru 1 and Waru 2 were 88% SiO2 compound, Waru 3 in the form of CaCo3 compound was 75.2%. SEM results with 10,000x enlargement Waru 1 is almost homogeneous in the form of slabs which identifies an uneven grain size and with a little porosity indicating the sample is partially amorphous in structure, Waru 2 shows an inhomogeneous sample with a fairly high porous dispersion and is not equally, Waru 3 shows the existence of an almost cube crystal form with high porosity so that it causes frequent landslides due to the density of a sand is still lacking so that it makes it easy for the land to be evicted because there are still many cavities in the soil.

Abstract

Kebijakan diversifikasi energi yang dikeluarkan Pemerintah Indonesia menuntut masyarakat untuk menemukan bahan bakar selain fosil. Penelitian ini bertujuan untuk menghasilkan briket dari campuran arang limbah baglog jamur tiram (JT) dan arang sekam padi (SK) yang berkualitas sehingga dapat digunakan sebagai bahan bakar alternatif. Penelitian ini secara garis besar dilakukan dalam tiga tahap yaitu pengarangan atau karbonisasi, pembriketan dan pengujian kualitas briket. Variabel yang digunakan dalam penelitian ini adalah komposisi campuran JT dan SK. Komposisi campuran yang digunakan yaitu 100% JT:0% SK untuk sampel A, 75% JT:25% SK untuk sampel B, 50% JT:50% SK untuk sampel C, 25% JT:75% SK untuk sampel D dan 0% JT:100% SK untuk sampel E. Dari hasil penelitian disimpulkan bahwa campuran yang paling optimal untuk mendapatkan briket berkualitas baik yaitu dengan komposisi 50% arang limbah baglog jamur tiram : 50% arang sekam padi dimana diperoleh nilai kalor sebesar 3541 kal/gr, kadar air 1.57% dan kadar abu 36.20%.
