Isobutyl Palmitate is used as plasticizers, namely materials that function to increase the workability and flexibility of plastics. Isobutyl palmitate is produced by reacting palmiti…
ABSTRACT Palm oil is Indonesia's mainstay commodity which plays an important role in the economic development of the Indonesian nation. One of the products produced from the oleochemical industry is fatty acid. Palmitic acid is one of the largest fatty acid fraction found in Crude Palm Oil (CPO). The process used is a hydrolysis process with raw materials of CPO (Crude Palm Oil) and water. The…
ABSTRAK In everyday life, many used aluminum cans that are found around us become waste that can interfere with environmental hygiene and it turns out that so far it has not been processed properly by recycling. This is because the largest canned beverage producer in Indonesia is currently lacking in canned waste treatment systems. This final project aims to press used beverage cans with a can…
ABSTRACT Many coal mining companies use motors equipped with Variable Speed Drive (VSD) in the mining process. Variable Speed Drive (VSD) is a power electronic equipment that functions to regulate motor speed, but the use of Variable Speed Drive (VSD) can cause new problems that can reduce power quality in the electrical system, the problem is harmonics. The current solution that is widely use…
ABSTRACT Screw conveyor is a type of conveyor often used to move semi-solid materials. This examination will analyze the stress on the screw conveyor type 12S624R by modifying the length of the shaft. According to the Screw Conveyor Catalog & Engineering Manual, the length of each screw shaft for a screw conveyor with a diameter of 0,3 meters is about 3,75 meters, if the screw conveyor need le…
ABSTRACT Leaf springs as a component of the suspension system function to absorb shocks from the road and wheel vibrations so that they are not transmitted to the vehicle body directly and increase the tire's grip on the road surface and support the overall weight of the vehicle, both the weight of the body, engine, passengers, frame and other loads supported on it. The old leaf spring used wi…
ABSTRACT Main object of this research is to perform experimental test on a clothes dryer using an air conditioning system. The air conditioning system varied into three type which is split type, windows type and portable type. This research has to be done using pre heat for 30 minutes before examination started. Examination was conducted to obtain the performance parameters of SMER, SEC and Dr…
ABSTRACT Dimethyl formamide ((CH3)2HCON) or abbreviated DMF is an organic compound in the form of a colorless liquid that can be mixed with water and most organic liquids. Dimethyl formamide can be used as a solvent in the peptide coupling process for pharmaceuticals, in the peptide production process, and in the production of adhesives, synthetic leather, film coatings, and others. The manufa…
ABSTRACT The development of industry has a positive effect in the form of increasing the national economy, but has a negative effect, namely heavy metal waste pollution. Copper ion (Cu2+) is one of the causes of polluted environment. The maximum limit of copper ions (Cu2+) allowed in environmental water according to the PERMENKES RI NO.492/MENKES/PER/IV/2010 is 1.0 mg/l. Pineapple leaf fiber h…

ABSTRACT This final project discussed abaout the design of an automatic temperature controller broiler for chicken broiler farm based an arduino uno as controller, LM35 as temperature sensor,light as heater and electric fan as cooler. The temperature required for broiler chicken is between 30ᵒC - 33ᵒC. if the temperature is above 33ᵒC then the electric fan will be active, if the temperat…
ABSTRACT In modern times like this in the name of electronic devices are needed by humans to facilitate daily activities. For example, onion cutting and peeling tools to facilitate activities at the age who are doing work, so that there is no need to cut and peel onions manually so that they cause a lot of wounds and pain on the eyes when cutting, therefore with the presence of this tool can r…
ABSTRACT Technology is applied to simplify every means needed for human survival. Indirectly technology has reduced humans needs in some routine activities that are usually carried out. The rapid development of technologyandits application in all fields can be a solution to solve problems faced by humans, one of which is pets at home. This tool utilizes a series of astable multivibrator IC 555…
ABSTRACT In general, toilets in Indonesia still use a manual system. Especially on the lighting system and toilet indicators are in use. Turning on the lights using a switch that you forgot to turn off has an impact on wasting electrical energy. Then it often happens that toilet users do not know the toilet is being used or not. This problem requires a solution or solution by updating the toile…
ABSTRACT The escalation of the human population and industrial activities induced the availability of energy sources to reduce. This energy crisis forced humans to save and look for alternative energy sources. The utilization of empty palm oil bunches waste was expected to be one of the solutions to overcome this energy crisis. The empty palm oil bunch waste and spent bleaching earth were empl…
ABSTRACT Methanol plant from glycerol is a good prospect in Indonesia. Until 2021, methanol is only supplied by one methanol producer located in East Kalimantan, namely PT. Kalimantan Timur with a production capacity of 660,000 tons/year. Therefore, the methanol plant from glycerol has a very important meaning for the acquisition of foreign exchange as well as employment. This article presents…
ABSTRACT The development of the palm oil industry in Indonesia tends to focus on food products, whereas the largest added value obtained is in non-food products used by the cosmetics, oleochemical, soap and detergent industries. Surfactants have nearly eight times added value when compared to crude palm oil (CPO and PKO). In general, surfactants are synthesized from petroleum and natural gas d…
ABSTRACT Every year, Indonesia experiences a rise in demand for benzyl alcohol. In addition to being a key component in other chemical industries, benzyl alcohol is frequently used in the production of medications, cosmetics, solvents, perfumes, and textiles.
