Abstract

Lampia Port is planned to be used by PT Sinergi Perkebunan Nusantara to ship its CPO (Crude Palm Oil). Before the plan is realized, it is necessary to conduct a study to determine the technical capacity of the pier structure. Therefore, in this study, a survey of the technical capacity of the pier was conducted to identify the condition of the existing pier structure. The survey includes measurements of the layout and dimensions of the pier structure, hummer test and carbonation test as well as visual observations. Based on the results of measuring the layout and dimensions of the pier, it was found that the shape of the pier is T-type consisting of a trestle with a length and width of 42.5 m and 6.0 m respectively and a pier with a length and width of 80.0 m and 10.0 m respectively. The number of piles for the trestle is 22 piles while for the pier is 64 piles. The pile diameter for trestle and pier is 508.3 mm. The hammer test results show that the concrete compressive strength of the pier structure ranges from K300-K400 which still meets the concrete requirements for the marine environment of K300. The carbonation test results show that the carbonation value is greater than 2.0 cm, so it is necessary to repair the concrete surface at least as deep as the carbonated area or as thick as the reinforcement concrete blanket. Visual observations show that the pier structure has not shifted but the beam and pile cap structures have experienced corrosion and carbonation.

Abstract

This research examines the impact of work motivation, professional competence, and school climate on teacher performance at SMAN 1 Karang Baru, Aceh Tamiang. Teacher performance plays a pivotal role in determining the quality of education, making it imperative to understand the factors that contribute to its enhancement. This study employs a quantitative approach, utilizing survey methods and multiple regression analysis to investigate these relationships. Data were gathered through a structured questionnaire distributed to 50 teachers, with responses analyzed for validity and reliability. The findings reveal that work motivation, professional competence, and school climate significantly influence teacher performance, with work motivation and professional competence exerting a more substantial effect compared to school climate. These results highlight the critical importance of fostering motivation through appropriate incentives, recognition, and career development opportunities. Similarly, the enhancement of professional competence through continuous training and pedagogical skill development is paramount. Although the school climate also plays a role, its impact is relatively moderate, suggesting that personal factors such as motivation and competence are more influential. The study underscores the necessity of targeted interventions to improve teacher performance, emphasizing strategies that enhance motivation and professional competence while cultivating a positive and supportive school environment. These findings are expected to inform policies aimed at advancing educational quality in schools.
