Abstract

This paper presents sentiment analysis in online reviews using Support Vector Machine (SVM) algorithm. This research aims to classify the sentiment of online reviews into positive or negative by utilizing the SVM algorithm. The dataset used in this research consists of online reviews from May 2020 to April 2024 from www.tripadvisor.com. The results show the effectiveness of the SVM algorithm in accurately categorizing sentiment in online reviews, with a high level of precision and recall. The findings of this study have important implications for understanding and analyzing sentiment in online content, and can be utilized in various applications such as market research, customer feedback analysis, and opinion gathering.

Abstract

The crew is the main element in running the ship's operations. It is important to procure or dispatch crew members. However, crew dispatch has a relatively long and drawn-out process and often crew members do not follow the process according to schedule, causing delays. This research is a qualitative study that aims to determine the causes of crew on board delays. Data collection in this study used interviews, observation, and documentation methods. The results of this study indicate that there are obstacles in the ship's crew process. From the results of data analysis, the causes of crew on board delays are due to several factors, namely delays in certificate revalidation, difficulty in finding candidates according to qualifications, and sudden changes in crew requests. Efforts that can be made in overcoming this delay problem include giving a statement letter and sanctions if you do not follow existing procedures.

Abstract

Dwelling Time is the time required from unloading a container at the port until the container leaves the port. Dwelling Time at the port is a problem that hinders the smooth flow of goods, causes high logistics costs, and reduces competitiveness. This study was conducted because of the problem of high Dwelling Time in several ports in Indonesia. This study covers three processes in Dwelling Time, namely Pre-Clearance, Custom Clearance, and Post-Clearance. The purpose of this study is to analyze the Implementation of Container Handling Procedures that Exceed the Stacking Time Limit (Long Stay) Against Dwelling Time at PT Terminal Petikemas Surabaya. This study uses a qualitative method with a purposive sampling technique. Data were collected through in-depth interviews with data sources. The data analysis methods used include data reduction, data presentation, and data verification and analysis. The results of the study indicate that the main obstacle in Dwelling Time is caused by delays in service users regarding the completeness of documents, which has an impact on increasing the YOR value during the loading and unloading process. Although Dwelling Time does not have a direct impact on export and import activities, the long duration will affect the performance of PT Terminal Petikemas Surabaya and ultimately reduce the company's income.

Abstract

This study aims to analyze the relationship between stress coping and cadets’ learning motivation in Vocational Maritime Education and to formulate relevant policies. The study population consisted of 95 first-year cadets’ at the Vocational Faculty of Maritime. The sampling technique used was saturated sampling, where all 95 cadets’ became research participants. Data collection methods included questionnaires, observations, and interviews. Data analysis was conducted using multiple regression analysis, with hypothesis testing performed using t-tests and F-tests. The results showed that Emotion-Focused Coping did not significantly affect learning motivation when analyzed separately. However, Problem-Focused Coping had a significant impact on learning motivation. When considered simultaneously, both coping strategies significantly influenced cadets’' learning motivation. Based on these findings, this study suggests the necessity of a comprehensive policy to help cadets’ manage stress. This includes providing guidance and counseling services and developing effective stress management training programs to enhance cadets’ well-being, reduce dropout rates, and increase learning motivation. Implementing these policies is expected to support cadets’ in achieving optimal academic performance and completing their education on time.

Abstract

Aktivitas pelabuhan berkontribusi signifikan terhadap degradasi lingkungan, seperti peningkatan emisi karbon, pencemaran air, dan penumpukan limbah. Kondisi ini menjadikan pelabuhan sebagai salah satu sumber tekanan ekologis yang perlu segera ditangani. Konsep Green Port hadir sebagai pendekatan ramah lingkungan dalam pengelolaan pelabuhan, namun implementasinya di Indonesia masih belum merata. Selain itu, kontribusi energi terbarukan dan manajemen limbah terhadap keberhasilan Green Port belum banyak diuji secara empiris. Penelitian ini bertujuan untuk mengkaji pengaruh energi terbarukan dan manajemen limbah terhadap kinerja lingkungan pelabuhan, baik secara langsung maupun melalui peran mediasi implementasi Green Port. Pendekatan yang digunakan adalah kuantitatif eksplanatori, dengan analisis menggunakan Structural Equation Modeling berbasis Partial Least Squares (SEM-PLS). Responden dalam penelitian ini sebanyak 77 pegawai tetap PT Terminal Teluk Lamong Surabaya, yang dipilih melalui simple random sampling. Hasil penelitian menunjukkan bahwa energi terbarukan dan manajemen limbah memiliki pengaruh langsung yang signifikan terhadap implementasi Green Port dan kinerja lingkungan. Selain itu, Green Port berperan sebagai mediator yang memperkuat hubungan antara variabel-variabel tersebut dan kinerja lingkungan. Temuan ini menekankan pentingnya integrasi kebijakan energi bersih dan sistem pengelolaan limbah dalam upaya mendorong operasional pelabuhan yang berkelanjutan dan ramah lingkungan.

Abstract

This study aims to analyze the effect of leadership style and work motivation on the performance of truck drivers at PT Manggala Kiat Ananda, East Java area. A quantitative approach with a survey method was employed. Data were collected through questionnaires distributed to truck drivers as respondents and analyzed using multiple linear regression analysis. The results indicate that partially, leadership style has a positive and significant effect on truck drivers’ performance. Meanwhile, work motivation does not have a significant partial effect on performance. However, simultaneously, leadership style and work motivation significantly influence truck drivers’ performance. These findings suggest that drivers’ performance is more strongly influenced by structural and leadership factors than by individual motivational aspects alone. In a work environment characterized by standardized procedures and strict operational regulations, effective leadership plays a crucial role in enhancing discipline, responsibility, and work compliance. This study implies that transportation companies should strengthen operational leadership capacity and manage work motivation in an integrated manner to sustain performance improvement.
