Hopper is one of the tools for loading and unloading on land which is used to
unload bulk loads. With the increasingly crowded activities at the special port of PT
Semen Indonesia at the Tuban branch, Hopper is expected to be able to improve the
quality of increasingly crowded demolition activities. The purpose of this research is
to find out the factors that influence Hopper in dismantling bulk cargo at a special
port of PT. Semen Indonesia branch of Tuban, and to find out the effect caused by
Hopper being ineffective in the demolition process at the special port of PT. Semen
Indonesia at the tuban branch.
In this thesis, the research method used is quantitative descriptive research
method which regulates a research method using several aspects such as data
collection through observation, literature study, interviews, documentation, and
discussion related to the numbers. In this thesis data analysis techniques use
Strengths, Weaknesses, Opportunities, Threats (SWOT), so data collection is added
with a questionnaire..
From the results of the study can be known factors that cause ineffectiveness of
Hopper in the dismantling process at a special port PT. Semen Indonesia tuban
branch. Among them are weather factors, old Crane Hock Cycle time (HCT), and a
valve opening system that is manual. Based on the results of the study, PT. Varia
Usaha Bahari branch Tuban made an effort to check the weather before and during
the event, replacing the manual Hopper valve opening system to become hydraulic.
Enactment of ship feasibility deterrence, so that HCT from ship Cranes does not
slow down Hopper performance. Thus PT. Varia Usaha Bahari can improve bulk
cargo demolition services at the Special Port of PT. Semen Indonesia branch of
Tuban.
Keywords : Effectiveness, Hopper, Hock Cycle Time (HCT), Bulk Cargo.
