and networking to stimulate Sustainable Energy’

19-20 October 2009

Venue: Semarang, Gran Candi hotel

Report composed by: Eindhoven University of Technology

October 2009

Project leader: Mara Wijnker

Lecturers: Camilo Rindt and Patrick van Schijndel

1. Background and introduction to the workshop

Diponogoro University (UNDIP) has been involved before in EWG activities, but TU/e and

UNDIP never co-operated directly. It was found appropriate to start co-operation by means of

a fast-track program in which UNDIP and TU/e could get familiar with each other. Compared

to the other Indonesian universities with whom TU/e has been working for several years,

UNDIP should also be offered the opportunity of organizing some additional activities. The

workshop in October was organized as part of this fast-track.

The workshop was organized by Joko Windarto (staff member of the Electrical Engineering

department and CASINDO coordinator at UNDIP) and Bambang Purwanggono (vice dean

IV for co-operation and development of the Faculty of Engineering). Venue was the Grand

Candi hotel in Semarang. The setting of the workshop was very good, as well as the

implementation. The workshop consisted of two days of presentations and discussions

(October 19-20, 2009). A detailed program can be found in Annex 1. The number of

registered participants was around 60, spread out over 2 days. The first day of the workshop

around 50 people attended, the second day around 40. Out of the 60 registered participants,

around 40 persons came from UNDIP, the others from industry and government.

Main objectives of the visit were to introduce the running research activities at TU/e on

sustainable energy to staff members of UNDIP who are interested in this field of research, to

discuss current ongoing research activities at both universities, and to explore the possibilities

for co-operation.

2. Report on workshop; discussions of interest; level of

presentations, conclusions of workshop

Day 1

On day 1 the workshop was officially opened by the rector of UNDIP, Prof. Susilo Wibowo,

in the presence of the dean of the Faculty of Engineering, Ir. Sri Eko Wahyuni, Ms.

Session 1 was started with a presentation of Dr. Joko Windarto who spoke about historical,

current and future programs of UNDIP on sustainable energy planning, followed by Dr.

Nazarudin Sinaga who talked about energy efficiency as research and business opportunity.

Session 2 and 3 on the first day were devoted to running research on sustainable energy at the

TU/e (invited presentation) and joint research and cooperation possibilities between UNDIP

and TU/e (group discussion). Mr. Camilo Rindt introduced around 10 examples of

sustainable energy research at the TU/e in about 75 min. There was little response from the

audience. A recommendation for the future is to prepare a presentation which also includes

easier accessible material for a broader audience.

To evaluate the research and cooperation possibilities the attendants were divided into 4

groups. Each group was asked to start formulating running research interests, followed by

brainstorming about research and cooperation possibilities. The results had to be presented in

a central feedback session. This led to the formulation of 16 research topics. Day 2 the list

was extended to 28. In the feedback session possible contacts at TU/e were given who best

fitted to the formulated research topic.

Day 2.

Day 2 consisted of 4 sessions by several lecturers and discussions by TU/e, UNDIP, local

government and the director of ENTEC, which is an Indonesian micro hydropower

construction company.

Day 2 started with a lecture on renewable energy feed stocks given by Patrick van Schijndel.

The presentation focused on different possible renewable energy feedstock and the rising

demand for electricity and fuels in Indonesia. Also several slides have been devoted to energy

efficiency and the urgency to change towards renewable energy feed stocks and thus the

demand for Undip to do their share of researching and teaching it was difficult to get the

audience active although some responses on stronger statements showed that the audience

was aware of the most important topics taught. Although in general knowledge of the English

language is on a high level it might still be advisable to use bilingual sheets and

documentations to overcome communication issues.

After this presentation, the organizers planned to have a discussion on the possibilities of

using different feed stocks. The organization was not present when the discussion should

have taken place and could therefore not provide any guidance. This was unfortunate as there

were people in the audience that had several questions regarding this topic.

In the second session the speaker from UNDIP, Dr. Hermawan, presented topics that had

overlap with the first session. It was expected that the speaker of Undip focused more on

research possibilities for Undip rather than the potential for renewable energy as the former

subject was defined as the workshop topic.

During the third session the presentation was given in Bahasa Indonesia. Its topic was the

energy policies of Indonesia. During the presentation there was to some extent a translation

into English to ensure that the TU/e lecturers could understand. The last part of this

presentation focused on renewable energy implementation in Central Java. It was a good idea

to show what kind of activities is actually ongoing in the region. In the afternoon in the third

session Mr. Gerard Fischer from ENTEC gave an overview of their experience in setting up micro hydro projects in Indonesia. The presentation showed that renewable energy

technology can be technically and economically feasible and also that almost 100% of the

technology and materials can be developed and produced within Indonesia.

In session 4 the list of research topics was extended and discussed. The planned discussion

did not so much materialize. Instead this opportunity was used by the audience to ask

questions, e.g. regarding how the Casindo project could finance research and staff exchange.

Pak Joko and Pak Bambang Purwanggono closed the workshop by means of two speeches,

wishing for a fruitful collaboration between Undip and TU/e. They also mentioned the

preparation of a MoU on the topic of renewable energy technology between both institutes.

General remarks and conclusions about the 2-days workshop

a) The location and setup of the workshop was good. All was functional and everything

started in time. A lot of students were recruited for assistance and that worked out

well.

b) It was a pity that there was no real workshop organizer (chairman) who clearly

explained the objective and tried to stimulate people to actively participate in the

discussions. Positive was that the Rector of UNDIP and the Dean of the Faculty of

Engineering were present at the start of the workshop. The Rector even provided the

opening speech.

c) From discussions in the workshop but also from personal communications it appeared

that staff members are rather pessimistic about raising research funds. They seem to

show a hesitating attitude towards research development. It shows that only part of the

staff is actually involved in research activities and others are not (yet).

3. Report on visit of laboratories and discussions with

lecturers

Wednesday morning October 21 was reserved for laboratory visits. Besides Joko Windarto

also Bambang Pudjianto, vice dean I for academic affairs of the Faculty of Engineering, and

both staff members and students of the Mechanical, Chemical and Electrical Engineering

departments were present (around 15 in total). The program consisted of 3 lab visits of 45

minutes each and a concluding lunch of 1 hour.

Chemical Engineering Laboratory

We visited 3 smaller labs: the instrumentation lab, the separation technology lab and the

energy and process engineering lab. The labs of Chemical Engineering are organized quite

well and appear clean. Some set-ups look impressive. Posters are used to summarize the

research work. We have been introduced to various set-ups and instrumentation, which are

summarized below.

We were guided around by Dr. Moh. Djaeni. Djaeni performed a computational study using

COMSOL to optimize a multi-stage adsorption dryer. He published on this topic together

with Wageningen University. This partly explains his positive attitude for research. We asked

him to hand over a list of publications of the Chemical Engineering department over the last

couple of years. During lunch he handed over a list including conference proceedings,

national and international journal articles. The list shows an active attitude of the Chemical

Engineering department in publishing their results.

Set-ups and measurement equipment presented:

- biogas digester set-up;

- set-up to upgrade bio-ethanol;

- set-up for catalytic cracking of plastic waste using zeolite;

- set-up for convective drying using zeolite adsorption;

- desalination set-up based on reversed osmosis;

- atomic absorption photo-spectrometer;

- gas chromatograph (to be set up)

- high-pressure liquid chromatography setup

Mechanical Engineering Laboratory

Also in Mechanical Engineering we visited several smaller labs: the tribology lab, the

metallurgy lab, the energy lab, the manufacturing lab, the metrology lab and the flow lab (the

names mentioned are not the official ones). The tribology lab is a virtual lab without any set-

ups or measurement equipment. Only computer simulations are performed. The metallurgy

lab: there was only a rapid prototyping set-up which appeared to be used for research. The

energy lab was introduced by Dr. Nazaruddin Sinaga (invited speaker in session 1 of the

workshop) with a presentation on the research topics of the last couple of years and the plans

for future research in cooperation with TU/e. From the presentation it appeared that they

switched research topic every year. Dr. Nazarudin Sinaga elucidated that the choice of

research topics was highly driven by project possibilities. In the presentation of his research

plans he made clear that he wanted to become a centre of excellence for smart driving. The

manufacturing lab is mainly used by students in practical exercises using classic or CNC

turning- and milling-machines. In the metrology lab we were only introduced to the 3D-

coordinate measuring machine. The flow lab looked the most impressive of the Mechanical

Engineering labs and consisted of several wind tunnels, a water channel and some engines.

We were guided around by Dr. Jamari who did his PhD at Twente University and acts now as

a student advisor of the graduate program. According to him the department of Mechanical

Engineering hosted 2 PhD-students in cooperation with Twente University. Also according to

him the department has national journal publications.

Set-ups and measurement equipment presented:

- hardness measurement set-up;

- set-up for rapid prototyping;

- large gas engine;

- dual-fuel engines equipped with self-made dynamometers;

- around 10 CNC turning- and milling-machines;

- around 10 turning- and milling-machines;

- 3D-coordinate measuring machine;

- 2 wind tunnels with different sizes and velocities;

- water channel;

- Diesel and petrol engine equipped with dynamometer and self-made consumption

meter.

Electrical Engineering Laboratory

In Electrical Engineering we visited 3 labs: the power lab, the communication lab and the

control lab. The power lab houses a high-voltage set-up, some set-ups made by undergraduate

students and standard measurement equipment for lab work. The communication lab seats

around 20 undergraduates for practical exercises using standard measurement equipment like

oscilloscopes. Also the control lab seemed to be used by only undergraduate students for

project work. It showed among other things a smart wheelchair, a rain meter and robotic cars.

4. Conclusions and recommendations

Conclusions

The following conclusions can be drawn from the workshop and the visit to the labs.

Possible research topics are formulated on which UNDIP and TU/e could work together

in the future.

Recommendations

The following recommendations can be given.

1. It is advisable to define the objective of a workshop well beforehand and to make sure

there is one staff member who can push and motivate the participants during all the

sessions It is also important that at the end of the workshop the topics discussed and

concluded are summarized and also that some kind of follow up is defined.

2. All the ins and outs of the CASINDO project were not known to the TU/e-

representatives. In principal that is not a problem but it is unavoidable that participants of

the workshop pose questions about it. To avoid confusion it is advisable to hand over a

summary of the main points in the project.

3. The presentation of TU/e on sustainable energy didn’t cover all research themes as

defined within the master program Sustainable Energy Technology and didn’t match

always with the scientific level of the participants. It is advisable to prepare a presentation

which also includes easier accessible material for a broader public and covers more

themes.

4. During the workshop research and cooperation possibilities are formulated by the

participants. It is important to give this a follow-up. In spring 2010 a delegation of the

scientific staff of UNDIP is visiting the TU/e. An option could be to partly use this visit to

explore in more detail these research cooperation possibilities.

5. Use of bilingual sheets can always be recommended if time allows for translation.
