power supply equipment, capacitors, etc.
Address: 1163 Inasato-machi, Nagano-shi, Nagano 381-2288

 More detailed information about this OJT schedule please look at the Attachment No. 1

B. MATERIALS AND EQUIPMENTS
The materials and equipments to OJT in JRC’s factory are:
1. Training Module for each section of training
2. Note book
3. Toolset for practice

C. RESULTS
1. First Week
First activity is go to Ueda for factory visit and tour on October 24th

2016, in Ueda factory there are produced marine equipment like radar
antenna, radar processing unit, Inmarsat satellite system, and operation
console also produced in Ueda factory. After factory visit and tour at Ueda
factory, directly go to Nagano factory for introduced factory by Mr.
Takagawa.
Nagano factory activity first is training about Weather Radar Operation
and Maintenance on October, 25th-27th 2016. First day of training Weather

2

Radar Operation and Maintenance is introduced about the weather radar
system, configuration and pilot project in Philippine.
Weather radar JRC have 3 type of band, there is:
a. S-Band Radar
b. C-Band Radar
c. X-Band Radar
The basic different of this 3 type weather radar is observation radius, SBand radar have observation radius 400km, C-Band radar 300km, and for XBand radar 80km. But, for X-Band radar have high accuracy rainfall sensor.
Second day activity is how to operate the weather radar, in this case
operated Rainwatcher X-Band Radar because this training also for Brazil
project. Radar Workstation PC used for control this weather radar like

control azimuth and elevation. Radar Workstation can make task for the
radar, usually task used for scanning schedule.
Third day activity is how to take out the one of unit from radar like TRX
unit. Purpose of this activity is for how to replacing the unit if the unit
broken and other purpose is for maintenance work. The last training was
explained about J-BIRDS software. This software usually install at Master
Station, for communication to Radar Station using broadband network.
Next training is lecture about New RTU on October 28th 2016 at Nagano
factory. RTU is equipment for interface sensor like rainfall sensor, water
level sensor. Not only interface for sensor, RTU have some interface like
Extension I/O, GSM Modem input. After training about New RTU, next
training is DAM control system. DAM control system consists of 4
subsystems, there is:
a.

Telemetry Subsystem
It used for data collection like rainfall data and water level data.

b. Dam Data Processing Subsystem
This subsystem for processing raw data from telemetry subsystem


3

c.

Gate Control Subsystem
For control the gate to open or not based on information from Dam
data processing subsystem

d. Dam Discharge Warning Subsystem
The function is for inform to people surrounding Dam and also warning
if dangerous condition.

2. Second Week
Next training is sensornet communication on October 31 2016 at Kawagoe
office, this training actually for Agam Project. The activity is how to change
sensornet topology, for example: from 6-6 (6 layers and 6 child) to 9-3 (9 layers
and 3 child).
Next activity is sharing session about how to use Pathloss 5.0C, this activity
held by JRC Jakarta staff. After finished, directly go to Nagano for next training.

On November 1 is training about telemetry system operation. At this time
the training is about radio equipment and repeater equipment for telemetry
system operation. Radio equipment consist of 3 units, there is:
a.

Transmitter NSE-1560 (150MHz band)

b. Receiver NRE-1560 (150MHz band)
c.

Power Amplifier NAH-1560 (150MHz band)

Radio equipment has 3 types of band, 70MHz, 150MHz, and 400MHz. The
transmitter output is 1W or 3W. When a higher output is required a power
amplifier can be added for power amplification, so can become 5W and 10W.
Next activity is training about repeater equipment, the outline is repeater have 3
types there is:
a.

V-V repeater

This repeater mean is VHF to VHF communication. For this repeater
used 2 frequencies (f1 and f2).

4

b. µ-V repeater
For this repeater mean is micro to VHF communication. Micro mean is
another media communication like radio link, fiber optic, etc.
c.

S/F repeater
Store and Forward repeater is different with 2 repeaters before. 2
repeaters before is real time repeater, but for this repeater is non-real
time repeater because this repeater will store or save the data for few
millisecond and forward to next node.

Next training is Discharge Warning System Operation, held on November 2
2016 at Nagano factory. Warning equipment has a same CPU and modem with
telemetry equipment, but the software different. In this case, the warning
equipment model is JYY-175. This warning equipment have amplifier 100W with

model NVA-369. This amplifier NVA-369 can handle maximal 3 speakers which
that are standard of JRC.
The last activity is visit to Nakano office and Shinjuku warning system held
on November 4 2016. Shinjuku warning system used many type systems like
used VHF radio, or used fiber optic.

CHAPTER IV
CLOSING

A. CONCLUSION
The conclusion that the writer can take from this on the OJT are:
1. The trainees know about JRC’s company in Japan, manufacturing,
assembling, etc.
2. The trainees already learn about JRC's products and technology
3. Increase the knowledge about products and systems of JRC such as DAM
Control System, Weather Radar Operation & Maintenance, Telemetry
System Operation, Discharge Warning System Operation
4. The trainee capability to increase in system engineering and technical.
5. The trainees understand what the responsibilities of an engineer.
6. This OJT provide some motivation for trainee to learn more about JRC
products continuously and working harder, so that trainees can become a
better engineer.
7. The trainees should be learn more about JRC products to have the ability
to be able to present JRC products to Indonesian market.

B. SUGGESTION
1. JRC factory in Japan very clean, orderly and tidy. Every room has high
security system. So, the trainees should be keeping clean and tidy every
time working at JRC factory. The trainees has a good habit during OJT in
JRC Japan, and it must also be familiarized in the JRC Jakarta Office
2. The trainer for weather radar lecture has very good knowledge about this
system. This lecture was explained by Mr. Okawara. The trainees can try
to operate RAINWACTHER at JRC factory directly. Weather radar systems
is little difficult, so trainee should be learn hard about this system and
need more time to learn for this segment.

7

3. Telemetry System and Dam Discharge Warning System lecture is very
interesting which it explained by Mr. Takagawa. The trainees learn clearly
and can try to operate the equipment at JRC factory directly.
(Wiko Fredy Guspa)

1. The item of training is too much for 2 weeks duration. So, I am no
understand some training because very short time. I think better only
few item of training but we clearly understand than very much item of
training but we no understand some training.
2. I think better we also visit Dam Management System in Japan not only
Warning System at Shinjuku.
3. For training Telemetry System and Dam Discharge Warning System not
so good training, e ause the trainer an’t e plain with English so Mr.
Takagawa needs to translate. This matter become take a time for
explanation, but the trainer very good knowledge and know so well
about the system because when we ask, trainer directly to answer.
