EEPIS-Online, From the 14 proposals approved by the DIKTI for PKM-T field (Student Creativity Program Technology and Engineering), EEPIS only be able to get a team to PIMNAS (National Students Science Week). Student team consisted of M. Vishwanathan, M. Masru, Oxi Purbaya and Anang Priyono. The group that gets assistance from Ir. Era Purwanto, M. Eng, Indhana Sudiharto, ST. MT and ST S. Endro Wahjono a senior are students who are in class B 3 D3 ELIN except Sam who is in class 2 D3 ELIN A.
The team can go to PIMNAS XXII in 2009 which will be held at Brawijaya University, Malang (21-25/08). This time PIMNAS theme is "achievement to Increase Competitiveness In order to build the Nation State".
Technology offered by the team led by Firman is titled “Intelegen Regulator Kompor Gas Elpiji†and as a final assignment of Firman and Masru. There were a lot of explosions caused by LPG leak in society; it becomes a reason for Firman to make this creation. There are a lot of gas leak detectors distributed in the community; this creation is the development of the existed tool. Most of the gas leak detector installed a solenoid valve on the pipe regulators. It still allows a gas leak in the tube. That’s why they take solenoid valve not in regulator pipe but in valve which directly connected with the tube. It was done because the gas density is lighter than air, so gas is always moving downward. If there was a gas leak, the gas will be detected by the sensor. Sensors that are connected to the module are able to make the solenoid valve work. With a microcontroller as a base module, the gas is changing into a voltage. As a result, the plunger will move downward so that the plug closes the hole on the port and prevent gas passing through the valve.
Placement of solenoid valve in the valve makes a point plus in this device. To support the device, they observed to PERTAMINA in Rungkut, Surabaya. Through repeated experiments, finally this device can detect the gas leak properly.
When asked about the preparation of the race before then, “our equipments are ready, but posters are still in the process, we are still preparing the exam of TA which will be conducted on day 21 coincided with the first PIMNAS" said Masru.
Masru also give advice to EEPIS students who want to follow the next PIMNAS to try to make a simple tool, easily applied and beneficial for the medium society. Agreed with Masru, Firman also reveals the same thing. "To bring our creative ideas, we must be sensitive to the condition of society" he added. (Dha / nnd)
