Abstract

Transport of liquefied hydrocarbon gases and their derivatives (methane, ethane, propane, butane, ethylene, propylene and other liquefied gases) is done using gas carrier tankers. Large gas carriers are equipped with re-liquefaction system to handle cargo during the process of loading, voyaging, and unloading. A reliquefaction system is installed on gas carriers to handle the Boil off-gas (BOG) problem. Operation constraints Reliquefaction system operating the reliquefaction system include the compound characteristics, liquefaction unit operating conditions, and system performance. These issues also hinder the BOG liquefaction process. This research sought to investigate the whole operation process of the system. This case study was conducted by observing the objects directly on the MT. Chinagas Legend vessel whose main cargoes are LPG. In case studies, research is carried out by studying the phenomenon of case problems that occur directly on the object. The identified problems and its resolutions could add valueable information to science. The research results revealed that MT. Chinagas Legend had a reliquefaction system with 2-stage or 3-stage options. The former type was used for butane (C4H10) cargoes and the latter was used for propane (C3H8) cargoes. The common problem in the process of reliquefaction systems was the presence of contaminants carried with seawater and clogging the filters. A leak in the intake or discharge valve slowed down the reliquefaction process and rendered it ineffective. The problems can be overcome through periodic routine inspections on components that are directly in contact with sea water, such as sea water filters.

Abstract

The urgency of this research is how a company is able to obtain better of HR performance, develop knowledge, improve service quality and can create competitiveness for the company. This study objective is to describe whether quality knowledge can encourage technical superintendent motivation so that it can improve technical superintendent work performance during monitoring and evaluation of inventory on board using computer-based applications and knowing quality knowledge can improve technicalsuperintendent work performance so as to realize the performance of monitoring and evaluation of inventory list on board effectively. The method used in this study is the explanatory method. Data collection was carried out online from the distributed instruments. The target population in this study were employees in the fleet division at 7 (seven) shipping companies which were used as research objects with a total number of employees of 160 employees. The data obtained is then tabulated, then data reduction is carried out and after obtaining proper data, calculations are carried out using the SPSS application by carrying out validity tests, variable reliability tests, normality tests and homogeneity tests. According to the results, it is known that there is a strength relationship between the knowledge quality and human resources performance.

Abstract

This study aims to examine the influence of career potential and motivation on performa kerja within ship manning agencies. Ship manning agencies play a crucial role in the maritime industry by providing crew members for vessels. Understanding the factors that contribute to enhanced performa kerja in this sector is vital for the efficiency and effectiveness of these agencies. The research problem revolves around identifying the extent to which career potential and motivation affect performa kerja among employees in ship manning agencies. Additionally, the study aims to explore the specific dimensions of career potential and motivation that have the most significant impact on performa kerja. To solve the research problem, a quantitative research approach will be employed. A survey questionnaire will be distributed among employees of various ship manning agencies, collecting data on career potential, motivation, and performa kerja. Statistical analysis, such as correlation and regression analysis, will be conducted to examine the relationships between the variables. Results of data processing and tests between variables using SPSS and SEM AMOS series 24 applications. The results of the construct variable tests showed that all constructs met the eligibility standards and the results obtained were that career potential had an effect on work performance of 0.893, the effect of motivation on work performance was 0.844. so that it meets the eligibility standard for Correlation > rtable, namely 0.3494. The results of the Amos SEM test show that all variable test results (estimated regression weights) are ≤ 1.96 so that the regression test results of all variables and indicators in this study are significant. The sample used in this research was sailors who attached ships to crew providing companies totaling 150 respondents. The objects of this research are two companies providing crew vessels in Jakarta, namely PT. Oceanindo Ship Crew Staffing Agent, PT. Scorpa Pranedya Utama.
