Cargo pumps are very important in the unloading process, especially crude palm oil cargo on tankers. In order for the cargo unloading process to run smoothly, a strategy is needed in the use of cargo pumps. This study aims to find out the factors that cause damage to cargo pumps and the strategy of using cargo pumps so that the process of dismantling crude palm oil in MT Koan can run smoothly. The research method used is qualitative descriptive with data collection techniques through observation and interviews. The results showed that cargo pump 1 operated better than cargo pump 2, with 77% of the operating time. Damage to the cargo pump is caused by leaks in the mechanical seal and clogging of dirt. Routine maintenance on cargo pump 1 is more frequent than cargo pump 2. The cargo temperature of crude palm oil is relatively low ranging from 39-40°C and there is a decrease in temperature at one observation point which causes the texture of the cargo to become very thick, thus interfering with the performance of the cargo pump. Based on the results of data analysis of the results of observations and interviews, it can be concluded that the factors that cause damage to cargo pumps at MT Koan are lack of maintenance, low load temperature and performance differences in both cargo pumps.

This research aims to provide information about Corn Maintenance Strategies in Bahal Batu III. Corn is a staple food along with rice, and can be used in various dishes as a side dish or snack. Corn not only contains carbohydrates, but also contains enough nutrients and crude fiber as a staple food which has a positive impact on health. Corn is also a substitute food or supplement for humans. Using the right amount of fertilizer will make corn plants grow more optimally. Measuring the growth of productive corn plants by applying various types of compound fertilizer to land in Bahal Batu III village and determining the most suitable type of compound fertilizer for the growth and yield of corn plants on the land. The survey was carried out on the land of Bahal Batu III village. Apart from that, corn can also be used as food for the community and has increased the price of corn consumption in society as a whole. Phosphorus is important for plant growth and yield, playing important roles such as encouraging flower and grain formation and strengthening thatch to prevent dropping and improve quality. The research results showed that even with different complex fertilizer compositions, all the parameters observed were plant height, stem diameter, number of leaves, ear length, ear diameter, number of seeds per row, seed weight per ear, and yield potential.
