Tips ngawur cara belajar sewaktu kuliah

Kalo sebelumnya gua nge-post di blog pake kata 'gua', sekarang ganti ah pake 'aku' biar lebih terkesan kalem gitu hahaha okelah, let's roll.... mari ngomongin tentang perkuliahan, perkuliahan berasal dari kata kuli, eh maaf, kata kuliah yang menurut KBBI kurang lebih artinya mengikuti pelajaran di perguruan tinggi.

 

Nah, kalo mengikuti pelajaran mah sama aja kayak SMA ga sih? Hmm ya kalo belajar mah sama sih, mau belajar di SD, SMP, SMA, kuliah, yang namanya belajar ya tetep belajar cuma caranya yang beda. Kalo biasanya waktu jaman old, jaman di Sekolah Menengah itu kebanyakan disuapin pelajaran sama guru, sementara di bangku kuliah? KADANG SAMA sih hahaha ya kegiatan belajar-mengajar di dunia perkuliahan sih menurutku kadang kita juga bakal disuapin materi, diajarin gimana caranya menyelesaikan soal tipe ini, tipe itu tetapi kalo katanya orang-orang sih misalnya ada mata kuliah dengan bobot 3 SKS, nah itu artinya 3 jam dialokasikan untuk belajar-mengajar di kelas which is dipandu sama dosen, 3 jam dipake buat belajar mandiri di rumah/kostan/kontrakan/apartemen dan 3 jam dialokasikan untuk berlatih soal dan penyelesaiannya (responsi kalo ga salah namanya).

Karena ini blognya aku, maka aku mau share sedikit pengalaman tentang bagaimana cara belajarku sewaktu masih berstatus anak kuliahan setahun yang lalu. Sejak SMA, aku bukan tipe siswa yang berprestasi dan punya nilai rapor keren cakep ganteng tinggi yang selalu naik podium juara, boro-boro ikut olimpiade huhuhu sejak SMA juga dan bahkan sejak SD kayaknya aku bukan tipe anak sekolahan yang tiap malam punya jadwal sekian jam untuk belajar, buka buku di rumah dan kebiasaan ini kebawa-bawa sampe di bangku perkuliahan dan parahnya lagi tuh biasanya aku kelabakan belajar itu pas udah mepet waktu ujian (UTS atau UAS).

Kok bisa udah tau itu cara yang salah tapi tetep dilakuin? 

Ya, kadang aku ngerasa aku mampu buat ngadepin ujiannya itu sih *bukannya sombong tapi ya gimana hahaha*, tapi kadang karena putus asa juga sih ga ngerti-ngerti wkwks ga deng, canda. 

Jadi gini, prinsip sesat dariku kalo belajar tuh bener-bener harus diserap maksimal saat di kelas, saat dosen sedang ngejelasin materi, apalagi kalo dosennya asik, cecar aja sama pertanyaan-pertanyaan terus sampe kita cukup paham. Selebihnya, jangan lupa catat apa yang menurut kita penting, biasanya sih catatanku itu ga panjang, cukup langkah demi langkah cara penyelesaian soal dan 1 atau 2 contoh soal aja, kalo mau contoh soal yang lebih bervariasi? Fotokopi aja ntaran punya temen hahaha

Kalo pas lagi males di kelas, males dengerin dosen, ngantuk, laper, badmood *halah* gimana dong?

Tenang, jika ga maksimal merhatiin pelajaran di kelas, masih ada temen yang pinter, baik, keren, cakep yang bisa dimintain tolong buat ngajarin. Ga harus temen juga sih sebenernya, itu bisa kakak tingkat, kakak senior lab gitu-gitu biasanya dengan senang hati kok ngajarin dan ngejawab pertanyaan tentang materi kuliah yang masih kita bingungin. Disinilah juga kita bisa belajar pelajaran hidup yang harus kita kuasai, bagaimana caranya membangun relasi dan komunikasi supaya terbangunlah keakraban sama pihak-pihak yang kita rasa mampu membantu kita kalo suatu saat kita stuck dan butuh bantuan informasi.

Balik lagi ke poin memahami materi secara maksimal di kelas, menurutku kalo udah paham sama materi di kelas tuh ya berarti kita punya peluang lagi untuk jadi lebih paham, hmm maksudnya tuh kayak orang-orang bilang, ilmu tuh kalo disampaikan dan dibagikan maka akan makin nambah dan lengket di otak kita. Nah, jadi buat kita yang udah merasa paham dan ngerti tentang sesuatu hal, bantulah temen-temen yang meminta bantuan belum ngerti, tawarin kalo perlu hehehe insyaallah segala sesuatu yang dengan ikhlas dibagi-bagikan akan ditambahkan oleh Sang Maha Pemberi.

Di saat udah mendekati ujian, ini beberapa hal yang biasanya aku lakuin:

1. Lengkapi catatan dan contoh-contoh soal, fotokopi beberapa lembar kumpulan soal KOPMA punya temen aja biar irit ga perlu beli full yang dijual di KOPMA. Karena biasanya ada kemungkinan kalo soal ujian itu akan mirip kontennya dengan soal-soal ujian sebelumnya, syukur-syukur cuma beda angka.

2. Pantengin jadwal responsi yang diadakan di lab-lab matkul bersangkutan yang biasanya diadain beberapa hari menjelang dimulainya minggu ujian, bukan cuma dari lab tetapi juga dari dosen-dosen yang biasanya di pertemuan-pertemuan terakhir di kelas bakal ngadain responsi.

3. Jika kurang puas dengan responsi umum itu, hubungi kakak tingkat atau kakak senior lab atau anak lab atau anak pinter yang bisa ngajarin, biasanya ini tuh forum tertutup gitu loh, maksudnya isi grup belajarnya cuma orang-orang tertentu doang gitu, nah disinilah pentingnya punya keahlian negosiasi hehehe

4. Paksa diri untuk belajar di h-seminggu sebelum minggu ujian dimulai, kalo aku sih biasanya hampir tiap hari tuh belajar. Karena menurutku, belajar mepet seminggu sebelum ujian tuh paling mujarab diserap otakku, belajar disini bukan belajar dari 0 ya tapi cukup sekedar review dari apa yang sudah dipahami dulu di kelas.

5. Banyak-banyaklah menyimak orang belajar, karena kalo udah ngerasa pede, udah pasrah siap menghadapi ujian, jangan malah tidur-tiduran doang, perbanyaklah nguping orang yang lagi belajar, ya hitung-hitung supaya kita ga lupa juga sama apa yang sudah dipelajari.

Mungkin baru ini yang kepikiran untuk ditulis disini, alhamdulillah dengan cara-cara seperti di atas, aku bisa selesai tepat waktu dan IPK juga ga jelek-jelek amat lah walau ga cumlaude, karena IPK bukanlah segalanya wahai teman-teman, ada faktor doa dan luck juga. Goodluck dan jangan lupa berteman!

Wawancara HR? Wawancara HC? Gimana sih itu?

Hello, long time no post here. Di postingan kali ini akan gunain bahasa Indonesia versi santai aja deh, biar maksud dan tujuan postingan ini dapat dicerna dengan baik. Berhubung lagi ada waktu senggang di sela-sela waktu ngantor di hari jumat ini, gua mau cerita dan berbagi pengalaman tentang apa yang sudah pernah gua lewati selama menjadi jobseeker yaitu tahap interview Human Resource atau Human Capital di beberapa perusahaan multinasional dan perusahaan nasional di Indonesia menurut pandangan gua sebagai kandidat yg ga begitu ngerti tentang mekanisme detail proses rekrutmen.

Sebagai seorang jobseeker tentunya sudah ga asing sama yang namanya wawancara atau interview, tahap ini bisa terbagi ke beberapa part sesuai dengan materi wawancara dan background si pewawancaranya. Contoh wawancara yang pernah gua jalanin itu mulai dari wawancara psikolog hingga ada yang namanya wawancara dari bagian Human Resource atau Human Capital, kesemua wawancara ini kebanyakan diletakkan pada tahap kedua atau ketiga proses rekrutmen karena tahap awal rekrutmen sih mostly tes psikologi tertulis maupun berbentuk online assessment atau initial user interview yang pernah gua ikuti di salah satu perusahaan multinasional telekomunikasi di Indonesia.

Kalo ngomongin tentang wawancara psikolog, biasanya tahap wawancara ini adalah bagian cross-check atau konfirmasi terhadap hasil tes psikologi yang telah kandidat kerjakan, baik itu psikotes tertulis maupun psikotes online. Menurut pengalaman gua, kalo wawancara psikolog itu kebanyakan materi yang ditanyakan berupa beberapa buah studi kasus yang mengharuskan kita menjawab dan memberikan solusi terhadap sebuah kasus tersebut menurut versi unique kita sendiri sesuai dengan sifat dan sikap kita, ada beberapa juga yang bertanya dan membahas tentang track record selama kuliah dan keluarga tetapi lebih banyak ke problem solving atas suatu kasus/permasalahan sih. Contoh pertanyaan di wawancara psikolog yang paling bikin gua kaget adalah "Selama kamu menjabat di posisi X di organisasi Y, coba sebutkan apa kecurangan yang pernah kamu lakukan?" BOOM!! Tentu jika dihadapkan dengan pertanyaan seperti ini, terlintas di hati kecil kita yang paling dalam ingin menceritakan dan membeberkan 'dosa' tersebut langsung PLEKKK kepada pewawancara, namun menurut gua untuk menjawab bagian ini, cobalah untuk memberikan jawaban tentang 'dosa' yang menurut kita masih ada celah untuk diberikan pembelaan setelahnya, sehingga kita ga keliatan salah-salah banget karena ada alasan demi kebaikan dibalik itu semua. Eaaaa. Yang terpenting, jangan bohong deh karena kalo bohong sama psikolog mah kemungkinan besar ketahuan hahaha

Nah selanjutnya bahas tentang wawancara oleh bagian Human Resource atau Human Capital, di tahap wawancara ini tentunya di suatu perusahaan itu memiliki bagian rekrutmen yang biasanya berada di bawah bagian HR atau HC. Wawancara HR ini biasanya membahas tentang background pendidikan, keluarga, organisasi, pengalaman kerja (kerja praktek juga bisa), pengalaman meng-handle suatu project, kontribusi saat mengikuti lomba dan pernah juga gua ditanyain hal-hal teknis yang berhubungan dengan posisi yang gua lamar dan jurusan kuliah gua, meskipun biasanya hal teknis yang lebih detail bakalan ada di tahap interview dengan user, mungkin saja hal teknis yang ditanyakan di wawancara HR ini dibuat untuk nge-test sejauh mana kesiapan kita sebagai kandidat karyawan mereka kalo ditanya hal-hal yang di luar dugaan. Oh iya, di wawancara HR juga sangat besar peluangnya ditanya mengenai pengetahuan kandidat tentang perusahaan yang dilamar, jadi sebaiknya cari tau dulu sejarah perusahaan, job-desc posisi yang dilamar, nama pejabatnya juga deh kali aja ditanya. Namun, menurut gua tahap wawancara HR (maupun wawancara psikolog) ini digunain buat menilai seberapa cocok pribadi si kandidat karyawan ini dengan budaya perusahaan dan bagaimana kesiapan si kandidat karyawan untuk bergabung dengan perusahaan, besar kemungkinannya hasil wawancara HR ini akan menentukan kandidat karyawan tersebut akan diteruskan proses rekrutmennya ke bagian/departemen/divisi apa nantinya saat di tahap wawancara dengan user.

Inti dari setiap wawancara ini yaitu sama, bagaimana kita bisa impress pewawancara tentang diri kita, memberitahu mereka apa yang telah kita kerjakan baik di bangku kuliah, tanggung jawab di organisasi, tugas-tugas di perusahaan kerja praktek, andil di lomba yang pernah kita ikuti dan tentunya apa yang bisa kita tawarkan terhadap perusahaan tempat kita apply. Tetap santai dan jujur, jangan melebih-lebihkan sesuatu yang tidak bisa kita kerjakan karena tentunya (jika luckily lolos ke tahap berikutnya) semua yang kita sampaikan akan ditanyakan lebih detail lagi pada tahap rekrutmen selanjutnya.

Pengalaman dari wawancara-wawancara yang sudah pernah gua ikuti sih, wawancara tahap ini berlangsung sekitar 20-40 menit tergantung dari seberapa antusiasnya pewawancara terhadap apa yang kita sampaikan dan juga seberapa clear jawaban kita ke pewawancara. Jadi, kalo wawancaranya cepat selesai tuh bukan berarti diri kita ga menarik, begitu juga sebaliknya wawancara lama bukan berarti kita orangnya bertele-tele, tetap percaya diri aja cuy. So, good luck dan jangan lupa berdoa!

Two-way Wireless Communication using Xbee (Part I)

Few months ago, I was wondering how to use Xbee for sending and receiving data wireless-ly. I looked for some references in internet but no tutorial had ever made for this. As we know that Xbee is a wireless transceiver (transmitter-receiver) device which operates in frequency of 2.4 GHz and this device communicates using serial communication. 

First, we have to understand how serial communication works from this picture below:

As we can see from the picture, serial communication will send data bit per bit or if we make a simple example by having 1 road from A to B, but this road is 1 way only so that if there are few vehicles which want to go to B from A, it must make a queue because the road is only limited for 1 vehicle at the time. The data transfer process will be slower indeed, but the other factor is that it depends on how wide is the channel we have, the wider channel we use for smaller data, the faster connection we can achieve for sure.

I understood about that serial communication and how it works, but the big question was how to make controlling and monitoring process by using Xbee, as we know that Xbee is also working on hall-duplex transmission that we can see the difference of it in this below picture:

In half-duplex data transmission, only 1 channel is available to be used in transferring data regardless it is from A to B or B to A. So, if a data wants to be transferred from A to B, the other data in B which will be transferred to A should wait for the channel available after data from A to B is completely arrived in B. From this comprehension, we can take a conclusion that it is absolutely possible to make two-way communication by using Xbee.

Xbee is using Zigbee protocol which can be configured to 3 kind of AT function; they are Coordinator AT, Router AT and End Device AT. For the simple explanation, Coordinator is used as aggregator to collect any kind of data which is sent to it from another device with the same PAN ID with it (PAN ID is such a network number), as long as i tried, Coordinator node can do both controlling (sending) and monitoring (receiving) data but in half-duplex transmission.

The other one is End Device AT, from experiments that i've done, End Device node is only able to send data and unable to receive data from the other node either Coordinator or Router. So Xbee with End Device configuration is good for sensor node in the Xbee network, sensor node only does sensing and producing data without needing any incoming control data (or etc) and then the data will be sent to the other node.

Router, as we can read that this node is used for forwarding data from End Device or the other Router node to the destination node. With this kind of ability, Router node is able to do receiving and sending data which makes this node has similar purpose with Coordinator but has less function such as authentication for security, forming network and etc. Thus, to make a two-way communication with using Xbee, we should only have at least 1 Router node and 1 Coordinator Node.

I will separate this thread into 2 parts, the next part will be discussing about the configuration and steps to an example of project. See you in Part II!

How to reach Karimun from Bandung or Jakarta (via Batam)?

I recently told about what Karimun looks like and where it is, and in this new post i would like to tell about how to get there by using airplane either from Jakarta or Bandung. Why do i want to write about it? Because some friends of mine usually think that visiting Kepulauan Riau especially Karimun is quite expensive. In fact, reaching Batam or Karimun is more cheaper than flying to Papua or even only to be arrived in Makassar.

As a student who studies in Bandung, i usually fly from Batam to Jakarta or directly to Bandung by using airplane but before that i have to sail to Batam first because i am from Karimun as well as if i go back to Karimun. It is certainly not possible to reach Java island by bus or car directly from Batam, because Kepulauan Riau is surrounded by sea and there are only 2 choices either using ship or flying with airplane.

Batam has a good international airport named Hang Nadim. Batam and Jakarta is connected by many airlines services, from low cost airlines until premium class airlines like Garuda Indonesia or Batik Air. The frequency of flight between Batam and Jakarta is more than 5 flights in a day. Besides Jakarta-bound flight, Batam is also connected to Bandung via direct flight operated by Lion Air and Citilink that each has 1 flight only in a day. Below i post snapped pictures from Traveloka website (accessed in February 22nd, 2017 at 6.30 p.m.) for flights operated from Jakarta to Batam:

and below is from Bandung to Batam:

For the ticket prices available on that website, there has almost similar price between flight from Jakarta and flight from Bandung. For example, we look at flight operated by Citilink, the difference is only about 22k between flight directly from Bandung to flight from Jakarta. Then let's talk about the other price we should have to pay including transportation to Husein Sastranegara airport in Bandung or Soekarno-Hatta airport in Cengkareng, Jakarta. We are not only having to take notice about transportation price to reach the airport but also about time we should take to get there.

I am living in Buah Batu region in Bandung, it is located in the south of Bandung city. First, let's detail about time and price we should have from Bandung to Karimun:

Buah Batu to Husein Sastranegara Airport takes 40 minutes or maximum 1 hour by using motorbike or gojek, if using self-owned motorbike only needs 10k rupiahs for driving to the airport for fuel. But if we take taxi, it almost spends 80k-120k rupiahs according to traffic condition and maximum time is 1 hour for standard road or 40 minutes via toll road. It's only max 1 hour to get airport in Bandung, and then 1 hour 45 mins to fly to Batam. After arriving in Batam, there is airport taxi which can be used to go to the harbour. There are 2 choices of seaport in Batam that serve ferry service to Karimun, they are Sekupang International Ferry Terminal which costs about 165k rupiahs from airport and it takes 30-45 mins according to traffic, otherwise for the nearest seaport from airport of Batam is Harbour Bay International Ferry Terminal which only needs 30 mins from airport with spending about 120k-135k rupiahs.

If it's compared to price and time we take from Jakarta, i usually use bus transportation operated by Primajasa directly from Batu Nunggal bus terminal to Soekarno-Hatta airport in Jakarta. Taxi service from Buah Batu to Batu Nunggal bus terminal spends about 30k-35k rupiahs and then for the bus service costs 110k rupiahs including baggage allowed 20kg. It takes 2.5-3 hours to reach Soekarno-Hatta airport in Jakarta from Batu Nunggal, Bandung. It takes longer time to be arriving in Batam if we're using transit in Jakarta first compared with flying directly from Bandung to Batam. Moreover, it cannot be predicted how many hour it will take to reach airport in Jakarta because traffic condition in Jakarta is rather difficult to be predicted.

After reaching seaport in Batam either it's Sekupang or Harbour Bay, ferry service to Karimun should be taken by paying ticket 90k rupiahs from Sekupang and 110k rupiahs from Harbour Bay excluding tax (last rechecked price in January, 2017). Ferry trip takes about 70 mins from Sekupang and about 95 mins from Harbour Bay. Ferry services are almost (and always) available in every 2 hours, the earliest is at 6.30-7 a.m. in the morning and the last is at 5 p.m. from Harbour Bay.

I think that's enough for this post. See you in next post and let's visit Kepulauan Riau! #wonderfulkepri

Karimun, the infamous paradise in Malacca Strait

Karimun, as shown in the picture below is actually located in the famous Malacca Strait in Kepulauan Riau province. It is only 90 minutes away from Singapore which is located in the north of this island and also only 60 minutes away by ferry from Kukup, Malaysia. Sometimes it's funny how i heard question from some friends such as "Karimun? Karimunjawa?", it's totally different between Karimun in Kepulauan Riau and Karimunjawa which is one of best tourism destination in Central Java province.

Photo by @arkurniadi

I also have been asked about how close this island from the other neighboring countries is, it is exactly as close as your eyes may be able to sight the skyscrapers in Singapore or lighthouse in coast of Malaysian if the weather is not too cloudy, but also it's sometimes having a good view when it is sighted after the rain. It also has a nice view in the evening because the lights of the skyscraper will be sighted from afar. Usually the people of Karimun spend the night of new year eve by gathering around the coastal area of this island which is faced directly to Malacca Strait and they are able to have a fabulous view of fireworks.

For reaching this island, there is a port (seaport) which serves some destinations like domestic destination to Batam or another island and also international destination such as Singapore and Malaysia. The ferry services are available all the day, it's usually started at 6 a.m. in the morning until the last service is usually at 5 p.m and 6.30 p.m. for the last arrival. Frequent ferry services serve Karimun and Batam route, it has 2 destinations to Batam from Karimun, they are Sekupang Ferry Terminal and Harbour Bay Ferry Terminal. Karimun seaport also has destination to Riau province such as Dumai, Bengkalis and surroundings.

Most of the people in Karimun use sea transportation for reaching another island including the central of trading in Batam or the capital city of Kepulauan Riau in Tanjung Pinang where 2,5 hours apart from Karimun. Moreover, there are 2 flights in a week fly from Karimun to Pekanbaru (capital city of Riau province) operated by Susi Air and it only takes about 1 hour to reach Pekanbaru instead of spending 6-7 hours if using sea transportation.

I will tell more about this island in the other post, writing more about the island where my home is located and my past was spent. Thanks for reading.

Welcoming speech

Hi, this is the first post of my new blog. I have already had few blog before, one of them was my academic (purpose) blog which is used for submitting some task(s) or just for sharing about my campus activity. My previous blog can be accessed in bimagty.student.telkomuniversity.ac.id, i have some posts (actually only 2 posts) there, those are about my internship program and about an advanced optical communication which is posted for completing my campus assignment.

In malayan or indonesian culture, there is some saying (or adage) like Tak kenal maka tak sayang or It will never be a love without knowing each other first. So i will introduce my self, usually some friends of mine call me Bima, i am 21 years young. For this blog, it will be written in some languages, they are English, bahasa Indonesia and even bahasa Melayu (Kepulauan Riau). I may be writing in bahasa Melayu-Kepulauan Riau because i come from an island in Kepulauan Riau named Karimun island (or Tanjung Balai Karimun as the capital) where the spoken language is bahasa Melayu or Malay but having some differences in some-word(s) with Malaysian spoken language, so that i can use that language well to be written in this blog aside from english or bahasa Indonesia.

I decided to write and share in blog because i think that writing in blog is very useful and more simple to express about my opinion in some issues. As we know, blog is accessible by using many kinds of gadget and can be accessed (or updated) wherever we are, as long as we can be connected to internet. In addition to share about my opinions, i will mostly try to post and write with using english as the main language because i want to improve my ability to write (and also read) in english quicker than before. For some mistakes that i will be doing in grammar or anything in english, it is such a good appreciation for me to have correction(s) and pardon(s) from the reader of this blog. ENJOY!
