Cargo oil pump is an auxiliary machinery on the ship that functions to
carry out the process of loading and unloading fluid by pushing the fluid
perpendicular to the pump impeller shaft. Centrifugal pump impellers will create
centrifugal force to push fluid from the center side of the pump (inlet) to the
outside of the impeller. So that the impeller rotates with mechanical energy
generated by the driving source.
The purpose of this study was to determine the factors causing mechanical
seal damage to the cargo oil pump, the impact caused by mechanical seal damage
to the cargo oil pump and efforts made to prevent the cause of mechanical seal
damage to the cargo oil pump in MT. Balongan The research method used by the
author in the preparation of this thesis is descriptive quality using a fishbone and
SHEL approach to facilitate data analysis techniques. The method of collecting
data that the authors do is by observation, interview and literature study.
Based on the results of research that the author has done, it can be
concluded that the mechanical seal damage factor on the cargo oil pump in MT.
Balongan is the application of PMS (Plan Maintenance System) which is not
carried out according to the provisions, the condition of the worn ball bearings,
the presence of rust deposits on the suction pump filter, and human error because
the engineers performance is less than optimal. The impact is a decrease in
pressure during the discharge cargo and one part of the pump has a leak and the
discharge cargo process is hampered. To prevent the factors that cause mechanical
seal damage to the cargo oil pump, the effort must be made is to apply a PMS
(Plan Maintenance System) must comply with the provisions, check and provide
lubrication for ball bearings periodically, clean the rust deposits on the suction
cargo filter oil pump, and intensive supervision of the work of engineers

REFLEKSI UNTUK MODERASI ISLAM-INDONESIA
No full textThis reflective article describes the author\u27s experience of the common attitude of Indonesian Muslims who are basically uncourageous and afraid of murder, violence, terrorism, radicalism, or the like. Indonesian Muslims prefer to moderate attitude than extreme one. Therefore, Indonesian Muslims--both individual and communal-- will always be moderate from the first onwards. Both experiences while living abroad (Canada) and notably in the country (Indonesia) proved to the author that Indonesian Muslims did not like violence. Moreover, the evidences suggested that the source of violence is external influence. One of related experiences on how Indonesian Muslims abroad tend to avoid violence was also experienced by the author during his lecture at McGill University, Montreal, Canada. In this article the author sketches briefly his story and conclude that the basic characteristics of Indonesian Muslims is moderate, and moderate Muslim trends or movements will be well acceptable and grow up. Artikel yang bersifat refleksi ini memaparkan pengalaman penulis tentang kesamaan sikap muslim Indonesia yang takut pada pembunuhan, kekerasan, terorisme, radikalisme dan sejenisnya. Muslim Indonesia lebih menyukai sikap moderat ketimbang sikap yang ekstrim. Oleh karena itu, muslim Indonesia—baik secara individu maupun kolektif—akan selalu moderat dari pertama kalinya hingga seterusnya. Kedua pengalaman—ketika hidup di luar negeri dan khusunya di negeri ini (Indonesia) membuktikan kepada penulis bahwa Muslim Indonesia tidak menyukai kekerasan. Bahkan, ada banyak bukti yang menyatakan bahwa kekerasan pada dasarnya berasal dari pengaruh luar. Salah satu pengalaman yang terkait dengan bagaimana Muslim Indonesia di luar negeri cenderung menghindari kekerasan juga dialami sendiri oleh penulis selama perkuliahannya di Universitas McGill, Montreal Canada. Di dalam artikel ini, penulis memaparkan kisahnya dan menyimpulkan bahwa muslim Indonesia itu berkarakter moderat dan gerakan-gerakan atau tren-tren Muslim moderat akan diterima dengan baik dan tumbuh
Enhancing Students’ Critical Thinking Skills and Motivation Using STEM Project-Based Learning (PjBL-STEM) Through a Simple Hydraulic Jack Project
Get PDFThis study presents an investigation of the use of STEM Project-Based Learning (PjBL-STEM) as a treatment in the experimental class compared to conventional learning in the control class in improving students' critical thinking skills and learning motivation. The focus of the study was Pascal's Law lessons with a special project in the form of developing a simple hydraulic jack. So far, science learning carried out in schools has made students complain, as it is still rote, teacher-centered, unrelated to real-life developments, and rarely integrates technology. This study, therefore, used a quantitative method with a quasi-experimental design involving 60 ninth-grade students in Pasaman Regency who were evenly divided into control and experimental classes using purposive random sampling techniques. Data was collected through a questionnaire on critical thinking skills and learning motivation, after the implementation of PjBL-STEM. The results demonstrated a significant difference between the two groups, with an independent T-test yielding a value of 0.24 for critical thinking skills and 0.33 for learning motivation. The PjBL-STEM model has been proven to improve student's critical thinking skills with an N-Gain of 0.46 (moderate category) and students' learning motivation with an N-Gain of 0.49 (moderate category).

Novelty/Originality of this study is the use of Outdoor Family Rice Farmers (TKUTLKL), together, the variable land area, income from rice fields, family income and cattle development patterns have a significant effect on the use of laborers outside the family's paddy fields. The coefficient of determination (R2) for this model is 0.56503, which means that 56.503% of the diversity of labor use in paddy fields outside the family can be explained by the variables of paddy yield, family income and cattle development patterns, while 43,497%.
 
Psychological Barriers in Science Education: Correlation of Science Anxiety and Academic Performance
Get PDFScience anxiety is a debilitating combination of anxious negative emotion and cognition in the context of science education. This study investigates the relationship between students\u27 science anxiety and their academic performance in science learning at the junior high school level. Employing a quantitative descriptive approach with a survey-based research design, the study gathered data from 109 students aged 12 to 15 years old. The Science Anxiety was used to assess students\u27 levels of anxiety across personal and environmental dimensions. The survey result shown that science anxiety scale scale among junior high school students is 2.31, which both of them considered as low category. The findings reveal a moderate, negative correlation (r = -0.509, p < 0.001) between students\u27 science anxiety and their learning outcomes. This inverse relationship suggests that as students\u27 science anxiety increases, their academic performance tends to decrease. Conversely, lower levels of science anxiety are associated with better learning outcomes. The results highlight the significant impact of psychological factors, particularly anxiety, on students\u27 engagement and achievement in science education. Based on the students’ answers to open-ended questions, they are feel comfortable when learning science at school because of kind and friendly teacher. On the other hand, students who feel anxious in learning science when they found difficulties to comprehend scientific formulas. The findings provide valuable insights for educators and policymakers to develop targeted interventions and strategies that foster a more positive and inclusive science learning experience for all students
