ABSTRACT Lubricants are widely used in mechanical systems to reduce energy loss and wear caused by friction. The problem of pollution to the environment caused by lubricants has attracted attention. Biolubricants are an alternative to lubricants that are clean for machines and renewable. To produce biolubricant is by transesterification. In this study, biolubricant was produced by varying the …

Regenerasi Kimia Adsorben Karbon Aktif Tongkol Jagung Dengan Variasi Kecepata…

ABSTRACT Activated carbon is known as an adsorbent with a large surface area and micropore volume, which gives it a high adsorption capacity in various applications, particularly in the removal of heavy metals from solutions. However, activated carbon used as an adsorbent in the adsorption process will eventually reach saturation when its adsorption capacity has been fulfilled. This leads to a…

Perencanaan Tempat Pengolahan Sampah Terpadu (Tpst) Di Kecamatan Bukit Raya K…

ABSTRACT Bukit Raya District is one of the sub-districts in Pekanbaru City with a population in 2023 of 107,347 people. Population growth and high consumption patterns cause an increase in waste generation which is only transported to Muara Fajar landfill without processing, thus reducing landfill capacity. To overcome this problem, the construction of an Integrated Waste Management Site (TPS…
