This study aims to: 1) describe the mechanism of the level 2 IQF (the Indonesian Qualifications Framework) descriptor development for electrical engineering, and 2) formulate a set of detailed-level-2 descriptors for electrical engineering. The method used to develop the descriptors is brainstorming between the researcher and several experts from both academicians and practitioners. Meanwhile, the method to formulate the IQF descriptors for electrical engineering is literature review referring to The Indonesian National Work Competency Standard (SKKNI) and focus group discussion involving experts from academicians, Professional Certification Institute Gema PDKB, the Association of Indonesian Electrical Works (APEI), Consortium for Electrical Installation Safety (KONSUIL), and industry practitioners such as PT. LEN Bandung, PT. Bukaka Teknik Utama, PT. Schneider Electric Indonesia, and PT. Smart Energi Semesta. The descriptors are in the form of the guttman scale questionnaire. The questionnaire was then tested on limited-scale respondents. The KR 20 method was employed to examine the reliability and resulted in r11 = 0.9;thus, the guttman scale questionnaire was considered "very reliable". The respondents consisted of 8 academicians, 8 electrical engineering teachers at vocational high schools, and 8 industrial practitioners. The collected data were then analyzed descriptively. This study resulted in a set of level 2 IQF descriptors which were designed according to the taxonomy of electricity system, namely electric power transmission system descriptors, electric power distribution system descriptors, and electric power utilization descriptors. In regard to electric power transmission system, 103 out of 154 (67%) descriptors were approved by more than 80% of respondents;for electric power distribution system, 83 descriptors (75%) were approved by more than 80% of respondents;and for electric power utilization system, 61 descriptors (94%) were approved by more than 8

Activated carbon is a versatile porous material that widely applied to purify, deodorize, decolorize, remove or reduce some gases harmful constituents and storage of gas. For different application different characteristics of activated carbon is required. This paper concerns to find out the characteristics of activated carbons derived from tabah bamboo (Gigantochloc nigrociliata) that physically activated with different activation holding time. Prepared tabah bamboo was carbonized by heating up to the temperature of 800 °C for two hours. The char produced was powdered and then activated physically by heating up to 800 °C, soaked at that temperature during each 1, 1.5 and 2 hours under 100 mL/min N2 flow. Activated carbons manufactured were characterized by proximate and ultimate analyses and SEM observation. The results show that the highest fix carbon (82.52%) and lowest ash (5.91 %) was obtained at 1 hour soaking time with moisture and volatile contents were 3.56% and 8.00 % respectively;the highest carbon (C) content of 84.16 % was yielded at soaked time of 1.5 hours;SEM observation shows that there were significant differences of morphology structure between raw material and activated carbons for all of the soaking time variations. The pores structures have been formed in the activated carbons produced. © Published under licence by IOP Publishing Ltd.

Research on the effect of T6 heat treatment and artificial life time on crystal size, density dislocation, hardness, and microstructure of Al 6061 alloy material made from powder metallurgy. The T6 heat treatment starts with a solid solution which is heated at 530 ° C, held for 60 minutes, then quenching into the water media, and the artificial aging process at 200 ° C and variations in the holding time of 1h, 24h, and 30h. Crystal size, dislocation density and lattice microstructure testing using X-ray diffractometer, hardness testing with Vickers scale and surface microstructure with SEM-EDX. Test results of crystal size, dislocation density, and micro lattice strain on 4 phase α-Al at the miller index plane (111), (200), (220), and (311) show that the crystal size increases with the duration of heating time of artificial aging. While dislocation density and micro lattice strain increase over a heating period of 1h to 30h, dislocation density and lattice strain decrease at the Miller index plane (111) to (311). The hardness testing of Al 6061 as-cast material was 54 HV after quenching the water hardness value of 75 HV, but after artificial aging the hardness decreased with a longer holding time from 45.50 HV to 39.95 HV. Microstructure observations with SEM-EDX, showed that the Al 6061 test sample without heat treatment showed a dominant α-Al matrix, whereas in the Al 6061 sample after the T6 process it was seen that the Mg2Si phase functioned to harden the Al 6061 alloy.

By using the principle of circular economy, the value of products and materials is maintained and utilized as long as possible, so that the landfill can be limited as little as possible. Electronic devices that are no longer used sooner or later will end up at the final processing site such as landfills or incinerators, where they will release toxic material into the air, soil and water, whereas the circular economy concept for e-waste can also be applied. Therefore, this research aims to make a small to medium size e-waste collection pilot project within the scope of UNTAR and UPH industrial engineering students, with participatoryergonomic approach. The research method used is action research anddata collected includes the number of core team students' participation, the amount of participation outside the core team, the form of participation, the network created, the average length of time for e-waste storage before donating, the amount of e-waste per category. In this project there were 102 students involved and divided into 19 groups. Total e-waste collected was 738 pieces.
