Distillation Apparatus ala SMPN 2 Karanggede
TAK ADA rotan, akarpun jadi (when there is no rattan, use a root) is an old saying which suggests that we need to find alternative solutions to problems. Suyatno, S.Pd, an IPA teacher at SMP 2 Karanggede, Boyolali, and his 9th grade students applied the saying. Though they have no distillation apparatus, they still did an experiment on distillation.
Pak Suyatno started by brainstorming the process of distillation and giving some examples of it in everyday life. After that, he showed the students how to make distillation apparatus. Next, he distributed the worksheet to his students and told them to make the apparatus. Students made the simple apparatus guided by the instructions on the worksheet. When finished, they tried the distillation process to make oil from Atsiri flowers.
Besides using Atsiri flowers for the experiment, students also used roses, jasmine and pandan leaves.
The result of this process can be used as fragrance or essence for making aroma therapy candles. One group reminded everyone that before doing the whole process it is necessary to ensure that there are no leaks and that there are no kinks in the pipe which could stop the process working. How much did it cost to make the apparatus? Pak Suyatno said that it was very cheap. The cost per unit was only IDR 9,000. From the experiment, students were able to produce fragrance. It is hoped that soon they can produce other things which have an economic value.

School Principals Group in Jepara Keen to Replicate
"FOR ME it is a great loss if we do not replicate the DBE3 program. DBE3 has made a great contribution and we need to make sure that the program is well disseminated. Therefore, I ask the Madrasah Principals Working Groups (KKMTs) to implement replication activities to all MTs in Jepara. The teacher certification program should not just be a formality. It must have substance and improve the quality of learning and the quality of teachers. We hope that DBE3 will help us."
That is the statement made by the Head of the Education Section of the Religious Affairs Office in Kabupaten Jepara, Drs. Ali Arifin, at a meeting with leaders of the KKMTs in his office. The meeting involved the leader of KKMTs 01, Drs. Alif Musyafak (also principal of MTsN Bawu Jepara); the leader of KKMTs 02 KH. Zubaidi (principal of MTs. Matholiul Huda Bugel) and the leader of KKMTs 03, Drs. H. Khamdi (principal of MTsN Keling).
They discussed the DBE3 replication program and agreed that it would take place between September 2009 and January 2010. The replication program involves all the KKMTs in Kabupaten Jepara, with 394 teachers from 88 MTs. The teachers involved are from the subjects of English, Mathematics, Bahasa Indonesia, Science, Social Studies and Civics.
