ABSTRACT Chip pin processing plays an important role in the pulping production process. Pin chip separation was carried out on the pin screen diamond roll acrowood machine which aims to separate pin chips from fines. A decrease in the performance of the diamond roll acrowood pin screen machine will reduce pulp production at PT RAPP. The purpose of this research is to study the factors influenc…
ABSTRACT Recausticizing Lime Kiln is one of the areas in PT RAPP which is responsible for producing white liquor cooking liquid for wood chip cooking needs in the digester. In the process, the causticizing reaction produces a byproduct in the form of lime mud (CaCO3) which can be converted back into burnt lime (CaO). This process requires a lime kiln unit to burn lime mud so that a calcination…
ABSTRACT At this time, one type of paper that is in great demand is the offset paper type. One of the qualities that must be met on offset paper is that the paper has a good internal bond. The internal bond value is closely related to the refining process, refining load and cationic starch. With the increase in the internal value of the bond, the strength properties of the paper will be better…
ABSTRACT Black liquor or WBL is obtained from washing pulp generally has a solid content of 15-16%. This WBL must be concentrated until it reaches 80-82% or it can be called Firing Liquor. The unit used to concentrate WBL is called evaporation plant unit. The results of the process in the evaporator unit are firing liquor and condensate. One of the condensates, namely condensate C (foul c…
ABSTRACT In the chemical plant department, chlorine dioxide is produced by reacting strong chlorate and hydrochloric acid. Strong chlorate is produced in the electrolysis process that occurs in the electrolyzer. Then, the strong chlorate that is formed will be reacted with HCl in the generator and then leave a weak chlorate solution which overflows to the evaporator. Weak chlorate evaporator i…

ABSTRACT It is indicated that most of the contributors to CO2 emissions in the air come from industrial cement. One of the materials that can be used as a substitute for cement in concrete mixes namely fly ash, but the use of fly ash can increase drying shrinkage which reduces the initial strength and mechanical properties of concrete. This study aims to examine the compressive strength, split…
ABSTRACT Friction Stir Welding (FSW) is a relatively new solid state joining process. This splicing technique is energy efficient, environmentally friendly and versatile. Initially FSW was developed only for metals such as aluminum, titanium and other materials that are difficult to weld by fusion welding. However, in recent years research on FSW for non-metallic materials such as polymers has…
ABSTRACT Trailer is an additional train in the form of a connecting train or an outboard train for transporting goods. The development of trailers for the needs of transporting of Selembayung ‘s Team energy-efficient cars which has been done before so it’s mobility to the training ground is quite constrained, therefore a standard flat bed type trailer is designed to facilitate the mobility…
ABSTRACT Catfish is a type of fish that is widely cultivated in Riau Province. This fish has a high growth rate and is not difficult to breed. However, after observing several fish farming ponds, it was found that the fish have different appetites at certain temperatures. Feeding should be done effectively and efficiently to save costs and prevent the pond water from becoming toxic to the fish…
