In this study, biosolid and wood waste biomass were used as fuel by turning them into fuel pellets. The purpose of making fuel pellets with various compositions was to compare the type of biosolid pellets and wood waste in terms of proximate testing. The benefits of making biosolid pellets can...

This research was conducted to synthesize and characterize hydroxyapatite-titania (HA/TiO2) composites and test their photocatalytic degradation activity on the remazol red RB textile dye. The chemical precipitation method was utilized to produce hydroxyapatite (HA) based on the converting of...

The removal of organic matter from the restaurant wastewater was investigated using the electrochemical oxida-tion method with multi carbon electrodes in a parallel construction. The degradation process was monitored by the measurement of COD concentration as a function of electrolysis time. The...

This research aimed to investigate the potential screening of wood degrading fungi to degrade the textile dye. Nine fungi were selected based on their ability to remove the turquoise blue textile dye on liquid potatoes dextrose médium. Fungal which have a high color removal efficiency were...

Dan biomassa limbah bambu dimanfaatkan sebagai bahan bakar dengan cara mengubahnya menjadi pellet bahan bakar. Tujuan pembuatan pellet bahan bakar dengan berbagai komposisi untuk mengetahui perbandingan jenis pellet biosolid dan limbah bambu ditinjau dari pengujian proksimat. Manfaat pembuatan pellet biosolid dapat mengurangi penimbunan sampah yang menyebabkan pencemaran lingkungan. Hasil penelitian menunjukkan Nilai kadar air tertinggi terdapat pada pellet dengan komposisi limbah bambu dan biosolid (90:10) yaitu sebesar 7,55%, nilai kadar abu tertinggi terdapat pada pellet limbah bambu dan biosolid dengan komposisi (50:50) yaitu sebesar 49,33%, nilai zat volatile tertinggi terdapat pada pellet limbah bambu dan biosolid dengan komposisi (90:10) yaitu sebesar 68,70%, nilai karbon padat tertinggi terdapat pada pellet limbah bambu dan biosolid dengan komposisi (90:10) yaitu sebesar 11,99%. Sementara itu, nilai kalor tertinggi terdapat pada pellet dengan komposisi limbah bambu dan biosolid (90:10) yaitu sebesar 3,692 kal/g. Kata kunci: biosolid, limbah bambu, pellet, proksimat, nilai kalor Abstract In this study, biosolid and biomass bamboo waste used as fuel by turning them into fuel pellets. The purpose of making fuel pellets with different compositions to compare the type of biosolid pellets and bamboo waste in terms of proximate testing. Benefits manufacture biosolid pellets can reduce the accumulation of waste that cause environmental pollution. The results showed the highest water content value contained in the pellets with bamboo and biosolid waste kompesisi (90:10) that is equal to 7,55%, the highest value of ash content contained in bamboo waste and biosolid pellets with the composition (50:50) that is equal to 49,33%, the highest value of volatile substances contained in waste bamboo and biosolid pellets with the composition (90:10) that is equal to 68,70%, the highest value of solid carbon contained in the waste bamboo and biosolid pellets with the composition (90:10) that is equal to 11,99%. Meanwhile, the highest calorific value contained in the pellets with bamboo and biosolid waste composition (90:10) in the amount of 3,692 cal / g. Keywords: biosolid, pellets, bamboo waste, proximate, calorific value

One of the fuels made from biomass are Charcoal briquettes. The biomass used in this study was coffee husk and coffee wood. This study aims to find out the ratio of coffee husk and coffee wood that accordance the briquette standards of the Minister of Energy and Mineral Resources (ESDM) and...
