The Symposium of ICNERE 2014

One of the important events for the researchers is a scientific conference, in which the researchers share their expertise and experiences  on research activities and built the networking among the researchers. It is therefore to intensify the event, University of Indonesia (UI) and Shizuoka University (SU) initiate a join conference on nano electronics research and education and it is defined as International Conference on Nano Electronics Research and Education (ICNERE). ICNERE is a bi-annual conference, the first ICNERE was organized in Bali-Indonesia in 2012 hosted by UI, and the second is organized by in Hamamatsu-Japan hosted by SU. The third ICNERE will be back in Indonesia hosted by UI in 2016, and the forth ICNERE will be in Japan again hosted by SU, and repeatedly bi-annually. The ICNERE is an open conference, meaning that participants are also from other universities beside UI and SU.

Cerita Tentang Pembuatan Peta Politeknik Negeri Bali (PNB)

Sebulan yang lalu saya ingin membuat peta digital Politeknik Negeri Bali (PNB) yang benar-benar baru dan berbeda. Tapi apa boleh buat, para guru besar memberi tugas-tugas harus didahulukan untuk dikerjakan. Saya juga diminta ke Denpasar untuk membantu Karang Taruna Satya Mahardika dalam lomba karang taruna kota Denpasar. Selain itu diperlukan banyak waktu ke PNB untuk melaporkan Penugasan Kembali serta mengajukan ijin Tugas Belajar S3 di Universitas Indonesia (UI). Sekembalinya ke Jakarta, kampus UI memberikan semangat baru untuk menyelesaikan peta ini. Sebagai mahasiswa S3 Teknik Elektro, saya memperoleh ruangan kerja tersendiri yang tenang, full ac, dengan dukungan koneksi internet kampus berkecepatan tinggi yang mampu mengakses berbagai jurnal internasional, bertempat di Gedung Engineering  Center FTUI . Pada ruangan ini juga disediakan water dispenser beserta teh, gula, dan kopi. Sungguh nyaman untuk berpikir dan bekerja dalam waktu lama. Kami menyebutnya ruang KD (Kandidat Doktor). Peta ini dibuat selama beberapa hari di ruang KD dengan konsekuensi pulang ke tempat kost yang semakin malam. Untunglah ada teman-teman yang bisa diajak pulang malam bersama, mengingat bis kuning UI, kendaraan dinas saya di UI, hanya beroperasi hingga pukul 21.00 WIB. Pernah saya merenung di ruang KD membayangkan selama belasan tahun saya bekerja sebagai di PNB, tidak juga dapat ruangan untuk bekerja  secanggih ini. Mungkin karena itu saya jadi jarang ke PNB dan lebih suka kerja sosial. Di Bali, kegiatan sosial kemasyarakatan sangat menarik bagi saya, sehingga saya pernah menjadi prajuru Banjar Catur Panca, lalu pernah ditugaskan sebagai pangemong Pura Jlih Lambih Pekambingan, serta juga dulu pernah aktif mengurus pecalang Tri Jaga Mandala, dan sekarang masih menjabat bendahara LPM Kelurahan Dauh Puri.  Aneh memang, karena sudah jelas pekerjaan sosial ini, PRnya banyak, tapi Rpnya sedikit. Malah sering harus keluar dari kantong sendiri. Lho, katanya cerita tentang Pembuatan Peta PNB, kenapa malah cerita  begini-begitu? Singkat cerita, setelah mencoba dengan berbagai cara, peta digital ini berhasil saya selesaikan walaupun masih perlu disempurnakan mengingat ada beberapa ruangan dan gedung di PNB yang hingga saat ini belum pernah saya kunjungi. Hasilnya dapat dilihat melalui link ini:

Mohon maaf jika ada bagian tulisan ini yang tidak berkenan di hati. Semoga peta ini bermanfaat untuk mengenalkan PNB kepada masyarakat melalui media internet.

Terima kasih kepada Dewa Gede Agus Tri Putra dan Fajar Surya Herlambang yang telah melengkapi informasi untuk peta  PNB ini. Juga untuk teman-teman yang telah melewati waktu bersama di Ruang KD, Gedung Engineering  Center FTUI.

Salam hormat saya kepada seluruh civitas akademika Politeknik Negeri Bali,

Anak Agung Ngurah Gde Sapteka.

Avalanche Photodiode (APD) Animation

This animation describes about an electronic device called Avalanche Photodiode (APD). The device is used to detect visible light by calculating the penetration depth of light, the concentration of its building block (layers) and the effect of dead space. The design of this APD device consists of five layers, namely p1+  layer, pi layer, p2+ layer, n layer and n+ substrate layer, with two regions of electric field, the drift region and the multiplication region (MR). The design takes advantage of the electric field with a range of 1.75 x 105 – 6.40 x 105 V cm-1 at the MR to cause avalanche phenomena.

Loteng Pesanggrahan

This post is part of  Site Map of Puri Denpasar.


Loteng Pesanggrahan (read lo – téng – pe – säng – gräh – än) positioned at the east of Jeroning Ancak Saji. There was a two-stories building here where the guest who visited Puri Denpasar stay. At that time, two-stories building like Loteng Pesanggrahan was very rare in Denpasar. Beside the building, there was a well supplied a good quality of water and also three stables so the guest could place their horses here. The site map of Loteng Pesanggrahan of Puri Denpasar is shown below.

Jeroning Ancak Saji

This post is part of  Site Map of Puri Denpasar.

Jeroning Ancak Saji (read je – ro – nïng än – cäk sä – jï) was the first yard of the palace. There were 4 units of Bale (read Bä – lé) here, 1 unit of well, and 1 unit of high building at south-west Corner called Panggungan (read päng – gung – än). The Panggungan was equipped with some steps made from stone. The King or Cokorda (read Co – kor- de) usually went to Panggungan in the evening to watch the cockfighting, and the people who pass the road. The position was very strategic because it was located at the corner of the cross road to Kesiman, Sanur, Sesetan and Pamecutan. It’s also near from marketplace. So, at that time, Panggungan was one of many favourite places for Cokorda Denpasar to visit.

The picture below described the layout of Jeroning Ancak Saji. The area was about 46.50 m by 45.50 m.  At north, there was an entrance gate to Taman Narmada. At east, there was an entrance gate (Sawangan Kembar) to Loteng Pesanggrahan.

Site Map of Puri Denpasar in Year 1906

Puri (read pu – rï) means balinese palace where the king and his family lives and rules his kingdom. Denpasar (read Den – pä – sär) is one of many kingdoms in Bali. So, Puri Denpasar means the palace of the king of Denpasar. It was located in the centre of Denpasar City. It was? Yes, because this old Puri was destroyed by Dutsch while they conquer the Kingdom of Denpasar in year 1906. Now in this site has been built as the residential of Governor of Bali in Surapati Street, Denpasar, Bali.

The Puri Denpasar has 171 meters length and 158 meters width. It has a thick wall, about 1,5 meters and 6 meters height. To enter the Puri, there are two dignified gates at west and south side of it. Inside it, the yards are separated by walls.The buildings were built from stones. Many of them have their own verandah. A lot of buildings in this palace and also a beautiful park called Taman Narmada.
