<![CDATA[Occupational Health and Safety (K3) is our effort to create a healthy and safe work environment so as to reduce the probability of occupational accidents and diseases due to negligence which results in demotivation and deficiency in work productivity. At PT. Equiport Inti Indonesia, the application of forklift operating safety regulations has not been carried out thoroughly. The non-implementation of the implementation of the regulations as a whole can trigger work accidents. The purpose of this final project is to find out the steps taken by the company in preventing work accidents in forklift operations. The method used in this final project uses interviews and direct observation in the company to fill in the checklist table that has been prepared as a data collection tool. The analysis in this final project uses a fishbone diagram. The use of fishbone diagrams is carried out to trace the causes and effects that arise from the deficiencies found that can lead to forklift work accidents. The results of this final project show that PT. Equiport Inti Indonesia still lacks in implementing safety standards in forklift operations, including the absence of pedestrian paths, incomplete forklift safety signs, and the operator's lack of seriousness in operating forklifts. From the results of this final project, it can be concluded that the company pays little attention to the procedures for implementing occupational safety and health in forklift operations.]]>

<![CDATA[There are two factors that determine the rate of heat transfer from hot water to air as a cooling medium, namely the contact time and the surface area between the phases, where to determine the performance of the cooling tower, the performance of the cooling tower needs to be identified. Because of this, research is needed which aims to determine fluid circulation in induced draft counterflow cooling towers and to determine the cooling ability with a standard inlet water temperature of 70oC and a standard outlet water temperature of 27oC. This research uses a structured or quantitative approach method where the research process is carried out by making a design and design of a cooling system which is then identified by measuring and calculating cooling towers. Based on research conducted on the mechanism of fluid circulation in induced draft counterflow cooling towers, it starts with hot water entering the tower being expelled through the nozzle, where the falling water will break and slow down as it passes through the filler. At the same time air enters through the inlet and passes through the filler, hot steam will be attracted along with the air and cold water will fall into the cold water pool. The cooling tower is capable of cooling water from a temperature of 70oC to a standard discharge temperature of 27oC with an average range of 44.38oC and an average approach of -0.67oC and produces an effectiveness value of up to 100% and a maximum heat absorption capacity of up to 225 kW.]]>

<![CDATA[The increasing development of science and technology is marked by the rapid progress that occurs with the creation of increasingly sophisticated equipment as well as security systems such as door locks. The design of this tool aims to increase the security of the door and to increase the power of creativity, innovation and expertise. This system uses an Arduino microcontroller board that functions as a control center, a fingerprint sensor is used to open the lock from outside and an ultrasonic sensor is used to open the lock from inside the room, and this system is equipped with a conventional key as an unlocker if a problem occurs in the system. The results of testing this tool on the fingerprint sensor, the test is carried out using five fingers, where three fingers have been registered and two fingers are not registered. Two fingers that have been registered can be read and one finger that has been registered cannot be read, this can occur due to several factors such as dirty sensor fingers, incorrect finger positions and others. In the ultrasonic sensor there is no problem with the sensor. This tool has the advantage that the level of security is higher than conventional keys and has a conventional key as a backup in case of a problem with the system. This tool also has the disadvantage that it must always be connected to a power source, but in the event of a power outage, it can use batteries. Some components of this tool will also heat up if it is continuously connected to a power source but can be overcome by using a heatsink or other type of cooler.]]>

<![CDATA[Hand washing is a simple activity, but it has enormous effects and benefits for health. Especially in this time of the covid-19 pandemic, we all have to wash our hands. Hand washing tools, both manual and automatic, have their respective roles. For manual hand washing tools, we still use our hands to turn the water faucet. So in the process of making this hand washing tool, we aims to design a hand washing machine with an automatic system and implement the design in the form of a product. From the results of the design of the automatic hand washing tool that we made, namely using a 4x4 hollow iron with a tool height of 145 cm and a width of 55 cm, while this automatic hand washing control system we use 4 components consisting of a proximity sensor, relay, IC 7805, electric water pump and produce a hand washing tool that can help make washing hands easier without having to turn the water faucet, because this tool has used a proximity sensor / motion sensor. Then the results of this design still need to be done further research and development, for example, such as adding a hand dryer in order to optimize performance.]]>
