    Abstract
    A materil such as charcoal briquet can be used as an alternative energy. This material has been regenerated from a coconut shell charcoal blended with organic glue. It has caloric value approximatly 5000 cal/gr with compressibility number is 2,64 kgf/cm2 To improve the quality both caloric value and compressibility number is an objective of this study. A coconut shell was carbonized at (600 - 700) lie in limited air condition. The charcoal formed then wascrushed, sized to (40 -60) in mesh. These particel were impregnated in uatrium silicate (Na2SiO3) solution under arange cocentration (0,1 - 1,0) %. The impregnant was blended with an organic glue then molded to be a briquet. These briquets were tested their caloric value and their compressibility. A maximum caloric value was obtained 8083,84 cal/gr with its compressibility number 4,45 kgf/cm2 in 0,2 % natrium silicate (Na2SiO3) solution.
     
    Briket arang adalah suatu sumber energi alternatif yang dapat diturunkan dari arang tempurung kelapa dan perekat, namun mutunya seperti nilai kalor bakar masih berkisar 5000 kal/gr dengan kuat tekan 2,64 kgf/cm2 ,untuk meningkatkan mutu ini maka perlu dilakukan penelitian lanjutan. Tempurung kelapa dikarbonisasi pada (600 - 700) ºC dengan udara terbatas, arang yang dihasilkan digiling dan diayak sampai (40 - 60) mesh. Partikel halus ini diimpregnasi dalam larutan natrium silikat (Na1SiO3) dengan variasi konsentrasi (0,1 - 1,0) %. Bahan ini (impregnan) selanjutnya dicampur dengan perekat organik dan dicetak menjadi briket. Briket ini diuji kalor bakar dan kuar tekannya, kalor bakar maksimum diperoleh 8083,84 kal/gr dengan kuat tekan 4,45 kgf/cm2 pada konsentrasi 0,2 % larutan natrium silikat (Na1SiO3).
