Dispersi Partikulat, No2, Dan So2 Dari Operasional Pltu Multifuel Boiler Pt. …

Particulates, NO2, and SO2 from Multifuel Boiler (MB) 21, 23/24, and 25/26 of PT Indah Kiat Pulp &; Paper Tbk have the potential to affect the health of the surrounding community, so this research is important. This study aims to determine the distribution pattern of pollutants emitted by sources based on measurement time, compare ambient air concentrations in the dry and rainy seasons, and com…

Analisis Efisiensi Degradasi Limbah Ampas Sagu Dan Kotoran Kambing Menggunaka…

The Black Soldier Fly Larvae (BSFL) is known to be able to effectively decompose various types of organic waste and convert it into compost. However, the high crude fiber content in waste will affect the effectiveness of BSF larvae to reduce the waste. The purpose of this study was to analyse the degradation efficiency of sago hampas and goat manure and the quality of decomposition residue comp…

Pengaruh Variasi Komposisi Kulit Batang Dan Ampas Sagu Terhadap Karakteristik…

Sago bark and sago pulp are biomass waste from the sago processing process that has not been optimally utilized. The high calorific value of sago bark and pulp, which is 4666.5 cal/gr and 4000 cal/gr, has the potential to be used as briquette fuel. This study aims to analyze the physical and combustion characteristics of briquettes mixed with sago bark and pulp, the concentration of PM2.5 from …

Analisis Pengolahan Effluent Two-Stages Uasb Reactor Menggunakan Pac (Poly Al…

Palm oil mill effluent (POME) is characterized by very high chemical oxygen demand (COD) and total suspended solid (TSS) of 33,600 and 12,667 mg/l respectively, which require treatment to remove these parameters. Treatment with biological reactors such as two-stages UASB can be used, but after passing through the biological reactor process, POME still contain high COD and TSS concentration of 9…
