Mining operations rely heavily on the performance and reliability of heavy equipment used in the production process. One of the most important hauling units in open-pit mining is the dump truck, which functions to transport overburden and coal from the mining front to disposal areas. Due to high operational intensity, dump trucks require effective maintenance management to ensure equipment reliability and reduce unexpected downtime. However, maintenance activities are often carried out based only on routine service schedules without analytical planning based on historical data. This study aims to analyze the implementation of forecasting methods in maintenance management to improve the effectiveness of dump truck maintenance planning in mining operations. The research was conducted during field work practice at PT Putra Perkasa Abadi Jobsite BIB, Tanah Bumbu, South Kalimantan. The data used were historical maintenance records of dump truck units obtained from the maintenance department. The research method used a quantitative approach with time series forecasting analysis to identify maintenance patterns and estimate future maintenance needs. The results show that forecasting-based maintenance planning can help companies predict maintenance requirements more accurately and prepare maintenance resources more efficiently. Furthermore, the implementation of forecasting methods can reduce unexpected equipment failures and support operational efficiency in mining activities.

Coastal areas are transitional areas between land and marine ecosystems that are very vulnerable to natural disasters, one of which is abrasion. Coastal abrasion is the process of erosion of coastal areas caused by wave activity, ocean currents, and human activities such as infrastructure development and sand mining. Ciberi Beach (Tanjung Ciberi) located in Enggros Village, Abepura District, Jayapura City, is one of the coastal areas that experiences continuous abrasion. Its strategic location and direct facing the Pacific Ocean makes this area very vulnerable to coastal erosion. Based on the author's experience while conducting Field Work Practices at the Papua River Basin Center (BWS Papua), it is known that abrasion has caused damage to public facilities and significant coastline decline since 2019 (Cepos, 2024). Strong suspicions arose from the community based on the results of interviews conducted that the construction of the Youtefa Bridge contributed to the acceleration of abrasion. Previous research also showed that the rate of abrasion in the Yos Sudarso Bay area, including Ciberi Beach, reached 0.89 meters per year. Therefore, this study aims to analyze the level of damage to Ciberi Beach due to abrasion during the period 2014–2024, and to provide recommendations for handling to reduce the impact of damage in the coastal area.

One of the fishing tools that is widely used by fishermen in the Pati waters of Central Java is the gill net. This tool has relatively higher productivity and efficiency compared to several other fishing tools because it can catch large numbers of fish when operated. It is one of the fishing tools that is environmentally friendly and popular to use because its operation is not too complicated and is good for development. The purpose of this Field Work Practice is to determine the effect of operational time of gill net fishing equipment on mackerel fish catches in. This Field Work Practice also aims to determine gill net operational times for mackerel fish catches. Data was obtained by conducting experiments from two different treatments, each treatment was repeated 16 times to obtain a total of 32 data. The research method used is the experimental fishing method using t-test analysis, homogeneity test, normality test.  The results of the T-test on 16 repetitions at 07.00-10.00 WIB and 15.00-18.00 WIB were with an average amount of 205.7 kg and 244.4 kg so that a sign (2-tailed) result of 0.004 < 0.05 could be obtained. From the results of the T-test, it can be concluded that H0 is rejected and H1 is accepted, meaning that there is an average difference between the results of tagkapan at 07.00-10.00 WIB and 15.00-18.00 WIB which is influenced by several factors. So it can be concluded that differences in gill net operational times have an effect on mackerel fish. The fishing operation time of 15.00-18.00 WIB is the best operational time compared to 07.00-10.00 WIB which is caused by oceanographic factors, technical factors and natural factors.

During the field work practice, the author observed that there were obstacles in placing pedis examinations on non-cooperative patients so that the examination was not optimal. This obstacle resulted in radiologists not being able to carry out their expertise properly. In addition, if the referring doctor asks for a repeat photo, it will give the patient an excessive radiation dose. With such patient conditions, a fixation device is needed so that the examination produced optimal results. Innovation efforts are needed to overcome this in order to improve services and prioritize patient safety. In addition, according to Lampignano & Kendrick, (2018), it is not permissible to force injured limbs or body parts into a certain position, the position must be adjusted according to needs. So that patients with multiple fractures require special treatment that is different from patients in general. The researcher designed a fixation device that can be used in the patient's supine and sitting positions without having to lift the patient's thigh, genu, and cruris bones and also without looking at the size of the patient's feet.

Placing appropriate Field Work Practices (PKL) for students is very important, because it can maximize the abilities and talents of each student so as to produce graduates who are ready to compete in the world of work. In choosing a place for PKL students at SMK Negeri 4 Malang, the problem that often occurs is a mismatch in students' needs for a PKL place. To overcome this problem, a computer system is needed in the form of a decision support system that can help students at SMK Negeri 4 Malang to choose the right PKL place for students. The decision support system developed in this research uses the Moora and Simple Additive Weighting (SAW) methods in deciding the placement of PKL students. Based on the final results of the decision support system in the form of ranking. Moora's advantages include being stable and strong, this method does not even require an expert in mathematics to use it and requires simple mathematical calculations. Moora also has a good level of selectivity because it can determine goals from conflicting criteria. Where the criteria can be profitable (benefit) or unprofitable (cost). The SAW method was chosen because this method determines the weight value for each attribute, then continues with a ranking process which will select the best alternative. Research is carried out by looking for weight values for each criterion, and then creating a ranking process that will determine the optimal alternative.
