Abstract

Human needs are increasing in the world of transportation, especially for two-wheeled vehicles or more. In the automotive world, especially cars, there are various kinds of systems that work. These systems work in conjunction with one another so that if one of these systems is damaged, the car will be damaged. such as damage to the cooling system which can cause overheating of the engine. Overheating is the occurrence of excessive heat above the engine's working temperature which is caused by damage to one of the components of the cooling system. The occurrence of overheating in the Hilux double cabin car engine is caused by a lack of coolant, the thermostat is not functioning properly, the radiator cap is leaking, the inlet and outlet hoses are cracked and the water pump is damaged. To avoid damage, preventive maintenance must be carried out.

Abstract

This research modifies the bottle jack to remove the electric motor bearing of a water pump with a jack capacity of 2 tons. Bottle jacks are generally used to lift vehicles such as cars. The bottle jack can be modified so that it can be used as a bearing removal device. In general, the way to remove the bearing is still manual, namely by hitting it. The purpose of making this tool is to make it easier to remove the water pump electric motor bearing. The specifications of the tool are that it has a height of 16 - 27 cm. The width of the tool is 6 cm and the maximum pressure capacity of the bottle jack is 2 tons. The trial results of the bottle jack modification tool to remove the water pump electric motor bearings obtained an average time of 45 seconds.

Abstract

The palm oil plantation and processing industry is a key industry for Indonesia's economy. Palm oil exports are an important source of foreign exchange earnings, and this industry provides employment opportunities for millions of Indonesians. According to data from the Indonesian Ministry of Agriculture, the total area of palm oil plantations in Indonesia currently reaches around 8 million hectares, twice the area in the early 2000s, with around 30% located on the island of Kalimantan. In an analysis of the factors affecting Indonesia's palm oil exports (Ditjenbun, 2018). This research method is a qualitative research that emphasizes more on the process and results, how a treatment and care occurs and how to handle it effectively. Conclusion, Preventive maintenance is carried out on bucket bolts, bucket chains, transmission chains, and buckets. Preventive corrective maintenance is carried out on gearboxes, transmission chains, sprocket bearings, buckets, and bucket chains. Preventive breakdown maintenance is carried out during the replacement of bucket chains, sprocket bearings, and transmission gears. There are various types of damage that commonly occur in Fruit Elevators, including: damage to buckets, sprocket bearings, gearboxes, oil seals, and bucket chains. The causes of damage generally come from wear and tear, lack of lubrication, or mechanical wear due to high workload. Daily, weekly, monthly, and annual maintenance has been carried out with respective procedures such as lubrication, component checks, replacement of spare parts, and overhaul. The implementation of this maintenance schedule has proven effective in reducing the frequency of damage. Component replacement history data shows that components such as liners, sprockets, buckets, and gearboxes have the highest damage rates, thus requiring special attention and periodic monitoring to prevent repeated damage.
