Nanopartikel yang menjanjikan untuk baterai pemasok listrik di daerah 3T

Skema katoda baterai logam-udara.

Peneliti di Laboratorium Elektrokimia dan Korosi, Departemen Kimia ITS telah mengembangkan teknologi berbasis nanopartikel mangan dioksida yang dapat digunakan sebagai pengganti katalis Pt yang harganya mahal untuk reaksi reduksi oksigen. Nanopartikel ini dibuat dengan elektrolisis larutan kalium permanganat dalam air. Dengan mengatur keasaman larutan, morfologi nanopartikel mangan dioksida dapat diatur menjadi nano-batang atau  nano-pipih.

Perangkat penyimpan energi elektrokimia merupakan komponen penting dalam jaringan energi masa depan untuk menyangga pembangkit dan pasokan energi yang diturunkan dari sumber terbarukan. Diantara beberapa kandidat potensial, baterai logam-udara adalah salah satu yang paling menjanjikan. Baterai ini tersusun dari anoda logam dan katoda yang menghirup udara dalam elektrolit yang sesuai. Katoda memiliki arsitektur berpori yang mengijinkan pasokan oksigen terus-menerus dari udara di sekitarnya, yang selanjutnya direduksi dengan adanya katalis (umumnya Pt).

Kedua jenis nanopartikel tersebut memiliki aktivitas katalitik yang bagus untuk reaksi reduksi oksigen dengan mekanisme 2-elektron. Keberhasilan pembuatan katalis murah ini mungkin dapat membantu untuk pengembangan baterai statis untuk daerah tertinggal, terluar, terdepan dimana tidak ada pasokan grid listrik.

Proceeding of NNS2013 has been published by AIP

ImageThe collection of papers presented on the 5th Nanoscience and Nanotechnology Symposium (NNS2013; Gallery) held in Surabaya on 23-25 October 2013 has been published online by American Institute of Physics (AIP) (AIP Proceeding vol. 1586). This proceeding is edited by Prof. Heru Setyawan, Dr. Widiyastuti and Dr. Siti Machmudah and is open access that can be downloaded freely.

The NNS is a high-quality international scientific symposium held every two year that brings together scientist and engineers interested in the nanoscience and nanotechnology. This symposium is held under the auspices of the Materials Research Society of Indonesia (MRS-id) and the Physics and Applied Physics Society of Indonesia (PAPSI). The 4th NNS was held in Bali on September 23-25, 2011. This year, the 5th Nanoscience and Nanotechnology Symposium (NNS 2013), in conjunction with The 2nd Japan Powder Technology Forum, was held in Surabaya on 23-25 Oktober 2013 and organized by Institut Teknologi Sepuluh Nopember (ITS), Institut Teknologi Bandung (ITB) and Padjajaran University (UNPAD) and supported by PT. Grafindo Nusantara and Horiba Scientific.

The aim of this symposium is to provide an up-to-date picture of the board research field of nanoscience and nanotechnology. Various topics concerning with nanoscience and nanotechnology, e.g., nanonaterials, nanoelectronics, etc., were discussed. Experts around the world shared new knowledge and exchange the knowledge and ideas in the field. This symposium was a good opportunity for the participants to learn together, to foster cooperation, to interchange ideas, and build capacity to get ready for any upcoming challenges.

We would like to extend our thanks to the Symposium Committee and our student helpers who run all aspects of the technical organization and program of this prestigious event. Special thanks go to our Plenary, Invited and Contributed Speakers and to all of you who came to Surabaya to present and share your own work. We are grateful to our sponsors for their interest and support for the symposium.

Within “the 5th Nanoscience and Nanotechnology Symposium (NNS 2013)” held by Study Center of Materials and Nanotechnology LPPM ITS on 23-25 October 2013 in Meritus hotel, Surabaya, the Department of Chemical Engineering ITS, cooperated with the Society of Powder Technology Japan, held “Japan Powder Technology Forum (JPTF 2013)”. Both NNS 2013 and JPTF 2013 were organized by our laboratory. The Forum was aimed to introduce the technological development related to powder/particle developed by Japanese companies to Indonesian companies/society. The program started at 13.00 p.m. and officially opened by Prof. T. Matsuyama, head of Kanto Section of the Society Powder Technology Japan. The forum was chaired by Prof. Wuled Lenggoro of Tokyo University of Agriculture and Technology.

The first speaker for the first session was General Manager and CEO of Ohkawara Kakohki Co. Ltd., M. Osuga dan M. Ohkawara, respectively. They introduced spray dryer technology with twin jet nozzle. This technology has been applied at many industrial segments including food, pharmaceutical, organic chemistry, inorganic chemistry, industrial waste, advanced ceramics, etc. The presentation was continued by speech by CEO of Makino MFG Co. Ltd., T. Makino, who discussed about pulverizer to produce rice flour. They developed a machine, that although the raw materials have different characteristics but have the same quality of products. The first session was ended by the talk by S. Nagare, PhD. from Nara Machinery Co. Ltd. They introduced their developed technology to modify particle surface and composite materials by hybridization system.

The second session was opened by a presentation about the application of industrial microwave on bulk solid handling processing by the president of Matsushima Machinery Laboratory Co. Ltd. One application of this technology is on the measurement of solid level in silo. The next presenter was president director of Nishimura Machine Works Co. Ltd. who talked about weighing and filling machine of powder. Then, president of Tokuju Co. presented about milling and classifying process. This session was closed with presentation by Dr. N. Aya of National Institute of Advanced Industrial Science and Technology who discussed about fine bubble technology and international standardization.

The Forum was attended by representatives from 14 Indonesian companies, namely: PT. Petrokimia Gresik, PT. Pupuk Kalimantan Timur, PT. Molindo Raya, PT. Grafindo Nusantara, PT. Trans Sulawesi Tenggara, PT. Trans Sulawesi Sejahtera, PT. Trans Jawa Sulawesi, PT. Ultimate Carbometal Nusantara Dua, PT. Carbonindo Nusantara Jaya, PT. Gunung Sabak, PT. Wali Mining, PT. Latambaga Raya, PT. Lasolo Karya Sejahtera dan PT. Mekongga Sejahtera. Two companies run business on production of fertilizer and the others mostly on mining and minerals production. The participants were very enthusiast with the discussion demonstrated by many questions arised during discussion sessions.

The forum was closed by the launching of Indonesian Powder Association to build better networking for developing powder technology. The association was established to answer the concern about  the neglect of development of powder technology resulting natural resources and minerals spreading around the area of Indonesia exported in the form of raw materials without added value. To overcome the problem, Indonesian Powder Association was established to build networking and cooperation among industries, universities and research institution. It is expected that technology transfer from universities and research institution from fundamental and applied research will be implemented.  The Department of Chemical Engineering ITS took an active role on establishing this association where one of its academic staff, Prof. Heru Setyawan, is head of international collaboration and has had collaboration with PT. Trans Jawa Sulawesi for developing magnesia processing.

The organization of the Indonesian Powder Technology is in the following.

– Chairman: Husni Thamrin
– Vice Chair: Budi Santoso, Surya Widjaja
– Secretary: Rudy Achmad Ridwan, Dr. Camellia Panatarani, M.Si
– Finance: Sylvia, Gloria Rizki Adiarti Wakil
– Head of Division:
* Research and Development Division: Dr. I Made Joni, M.Sc.
* Corporate and Development: Anton Rianto, Hartono
* Laws and Legal: Aji Setiadi, SH
* Communication and Human Relation: Haddy Arief, RA. Vitadevi Wing Wiryawan
* Organization and membership: Deden Sukarna
* International Collaboration: Prof. Dr. Heru Setyawan
* International Relation: Prof. Dr. Wuled Lenggoro
– Inspectors: Suratto S., Yorrys R., Deddy A. Soemanegara, Prof. Dr. Ganjar Kurnia

There are 11 companies that have joined the Indonesian Powder Association as corporate members. The eleven companies are: PT. Grafindo Nusantara, PT. Trans Sulawesi Tenggara, PT Trans Sulawesi Sejahtera, PT Trans Jawa Sulawesi, PT. Ultimate Carbometal Nusantara Dua, PT Carbonindo Nusantara Jaya, PT Gunung Sabak, PT Wali Miniing, PT Latambaga Raya, PT Lasolo Karya Sejahtera and PT Mekongga Sejahtera. Most of the companies are on the mining and minerals business. We hope there will be more companies from various fields of business join this association in the near future to support and contribute to the development of Indonesia.
