| Summary: | The world of coal mining is a field of work that has a high risk. Open requires
achieving production without compromising safety aspects. There are types of
heavy equipment to support coal mining operations. One type of heavy equipment
is a mining material pushing tool called a dozer. Dozers generally work in areas
near cliffs that are prone to landslides, where these areas can be classified as
dangerous areas. New technology is needed to increase the safety of dozer operators
from the threat of danger when operating a dozer. Teleremote dozers are one
method that can reduce the risk of accidents that can happen to dozer operators.
Instead of operating the dozer from inside the cabin, the operator operates the dozer
via a remote control device. There is an important aspect in operating a teleremote
dozer, namely the need for a signal that will transmit data and commands from the
remote control to the dozer unit operating in the field. Good and uninterrupted
signal quality is the main key to good teleremote dozer operations with minimal
risk.
The wireless signal network system currently used by companies will enter its
obsolete period. However, the old system was tough and not easily damaged. There
are strategic options for supporting the signal network for teleremote dozer
operations: maintaining the old network system, replacing it with a new one, or
using the old and new systems in a hybrid manner. Because there will only be one
strategy chosen, a decision must be made. The SWOT AHP method is used for
decision making regarding the strategy to be taken. The results of the AHP SWOT
will produce a strategy, which will become a benchmark for making subsequent
alternatives. Determining alternative types of network systems to support
teleremote dozer operations will use the AHP method.
There are criteria and sub-criteria that appear based on SWOT, where the Strength
criterion, with the Enhanced Capability sub-criterion being the strongest factor in
the criteria according to respondents' choice was 46.4% and Global Priority was
28%. Alternative strategies that emerge from the AHP SWOT results will be used
as a reference for determining next steps. Alternative strategies that emerge are
maintaining the old communication network system, replacing a new type of
network system, or using the old and new systems in a hybrid manner. AHP results
for the best alternative strategy are replacing a new type of network system with a value of 57.6%. After the strategy is obtained, it will continue with the stage of
determining the type of new system that will be used. There are several technical
and commercial criteria and sub-criteria that will be used as weights to determine
the 3 available alternatives: Small LTE, Private LTE, and Kinetic Mesh. The
priority criteria for determining alternatives is redundancy with a Global Priority of
23.9%, and the alternative chosen is Kinetic Mesh with a weight of 66.8%.
