This final project aims to make a racing camshaft grinding machine so that the work on making the camshaft becomes easier because the machine grinds the camshaft according to that desire. The method used is starting from field surveys, ideas, literature studies, manufacture, assem…
ABSTRACT The business opportunity for coconut shell charcoal briquettes in Indonesia is very large. Utilization of coconut fruit is oriented towards fruit flesh to be used as copra, oil and coconut milk for household needs, while by-products such as coconut shells have not been utilized much. Modifications were made to the blade, namely changing the distance between the fixed blade and the mov…
ABSTRACT Pyrolysis is a process of thermo chemical decomposition of solid materials into solid, liquid and gaseous forms through endothermic reactions. Therefore, the design of a pyrolysis reactor is very important so that the pyrolysis temperature can be reached so that products that can be used are formed, including charcoal, bio-oil, and flamable gas. The life of modern humans depends on th…

ABSTRACT The rapid development of the oil palm plantation industry is currently causing more and more waste to be formed, one of which is palm oil frond waste. Palm fronds have a carbon content of 81.25% which is quite high so that they can be used as activated carbon as an adsorbent which is useful for anticipating or minimizing Cu2+ ion pollution in the environment. This study aims to study …

ABSTRAK A tool for measuring and storing 3-phase induction motor current data that is useful to help the public know where the damage to the induction motor has the smallest percentage of damage to the 3-phase induction motor rotor so that it can be monitored so that further damage does not occur. This tool is equipped with Arduino Uno as a control center to process current sensor data which i…
ABSTRACT This fish feeding tool is very useful to help the community in raising fish, this tool can provide fish feed automatically. This tool is equipped with Arduino Uno as a control center to process proximity sensor data as a feed detector and RTC as a time setting that will be displayed on the 16×4 LCD as time information and feed availability. If it has entered the predetermined feed sc…
ABSTRACT The temperature of the human body can easily change according to the surrounding temperature. Indonesia's tropical climate and global warming are also other factors that make the weather unpredictable. To overcome this problem, a tool is needed to help stabilize the temperature in the human body. One of these auxiliary tools is a fan, but the fans that are widely used today are still …
ABSTRACT Microcontroller technology in industry is programmed in such a way as to be able to control equipment or machines automatically, in order to save time and human effort, for example problems in the parking system, can be controlled by technology, by designing a simple parking system using a microcontroller. Based on this, the researcher felt the need to make an automatic car parking r…
University of Riau ABSTRACT The design of an IoT-based electrical equipment monitoring tool using a smartphone is made in order to facilitate the use of monitoring and managing the use of electrical energy via the internet network. This electricity monitoring tool is equipped with NodeMCU ESP8266 as a microcontroller that processes data from the PZEM-004T module and sends data to the Blynk Io…
ABSTRACT Build-up automation of separator machine palm oil’s stick is a machine which is made for separate between the leaf and the palm oil’s stick easily. In addition, this machine was made so that the user can do separation without a risk of the sharp objects. The propulsion of this machine uses a single phase induction motor with motor power of 70 watts. Operation of this machine is us…
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…

Soebrantas Street–Adi Sucipto Street, According to Lancang Kuning Zebra Operation in October 2022 still found many drivers which violated and unobedient to traffic law. The violation is dominate by motor cycle drivers amount to 61 units, the violation happen to motorcycle driv…
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…
