"Saat ini kompetisi di industri telekomunikasi semakin ketat. Perusahaan telekomunikasi yang dapat tetap menghasilkan banyak keuntungan yaitu perusahaan yang mampu menarik dan mempertahankan pelanggan di pasar yang sangat kompetitif dan semakin jenuh. Hal ini menyebabkan perubahan strategi banyak perusahaan telekomunikasi dari strategi 'growth '(ekspansi) menjadi 'value added services'. Oleh karena itu, program mempertahankan pelanggan ('customer retention') saat ini menjadi bagian penting dari strategi perusahaan telekomunikasi. Program tersebut diharapkan dapat menekan 'churn' 'rate 'atau tingkat perpindahan pelanggan ke layanan/produk yang disediakan oleh perusahaan kompetitor. Program mempertahankan pelanggan ('customer retention') tersebut tentunya juga diimplementasikan oleh PT Telekomunikasi Indonesia, Tbk (Telkom) sebagai perusahaan telekomunikasi terbesar di Indonesia. Program tersebut diterapkan pada berbagai produk Telkom, salah satunya Indihome yang merupakan 'home services' berbasis 'subscriber' berupa layanan internet, telepon, dan TV interaktif. Melalui kajian ini, penulis akan menganalisa penyebab 'churn' pelanggan potensial produk Indihome tersebut, sehingga Telkom dapat meminimalisir angka 'churn' dengan melakukan program 'customer retention' melalui 'caring' yang tepat. Mengingat ukuran 'database' pelanggan Indihome yang sangat besar, penulis akan menganalisis data pelanggan tersebut menggunakan metoda 'Big Data Analytics'. 'Big Data' merupakan salah satu metode pengelolaan data yang sangat besar dengan pemetaan dan 'processing' data. Melalui berbagai bentuk 'output', implementasi 'big data' pada perusahaan akan memberikan 'value' yang lebih baik dalam pengambilan keputusan berbasis data.

"Perkembangan teknologi informasi dan internet dalam berbagai sektor kehidupan menyebabkan terjadinya peningkatan pertumbuhan data di dunia. Pertumbuhan data yang berjumlah besar ini memunculkan istilah baru yaitu Big Data. Karakteristik yang membedakan Big Data dengan data konvensional biasa adalah bahwa Big Data memiliki karakteristik volume, velocity, variety, value, dan veracity. Kehadiran Big Data dimanfaatkan oleh berbagai pihak melalui Big Data Analytics, contohnya Pelaku Usaha untuk meningkatkan kegiatan usahanya dalam hal memberikan insight yang lebih luas dan dalam. Namun potensi yang diberikan oleh Big Data ini juga memiliki risiko penggunaan yaitu pelanggaran privasi dan data pribadi seseorang. Risiko ini tercermin dari kasus penyalahgunaan data pribadi Pengguna Facebook oleh Cambridge Analytica yang berkaitan dengan 87 juta data Pengguna. Oleh karena itu perlu diketahui ketentuan perlindungan privasi dan data pribadi di Indonesia dan yang diatur dalam General Data Protection Regulation (GDPR) dan diaplikasikan dalam Big Data Analytics, serta penyelesaian kasus Cambridge Analytica-Facebook. Penelitian ini menggunakan metode yuridis normatif yang bersumber dari studi kepustakaan. Dalam Penelitian ini ditemukan bahwa perlindungan privasi dan data pribadi di Indonesia masih bersifat parsial dan sektoral berbeda dengan GDPR yang telah mengatur secara khusus dalam satu ketentuan. Big Data Analytics juga memiliki beberapa implikasi dengan prinsip perlindungan privasi dan data pribadi yang berlaku. Indonesia disarankan untuk segera mengesahkan ketentuan perlindungan privasi dan data pribadi khusus yang sampai saat ini masih berupa rancangan undang-undang.

The development of information technology and the internet in various sectors of life has led to an increase in data growth in the world. This huge amount of data growth gave rise to a new term, Big Data. The characteristic that distinguishes Big Data from conventional data is that Big Data has the characteristic of volume, velocity, variety, value, and veracity. The presence of Big Data is utilized by various parties through Big Data Analytics, for example for Corporation to incurease their business activities in terms of providing broader and deeper insight. But this potential provided by Big Data also comes with risks, which is violation of one's privacy and personal data. One of the most scandalous case of abuse of personal data is Cambridge Analytica-Facebook relating to 87 millions user data. Therefor it is necessary to know the provisions of privacy and personal data protection in Indonesia and which are regulated in the General Data Protection (GDPR) and how it applied in Big Data Analytics, as well as the settlement of the Cambridge Analytica-Facebook case. This study uses normative juridical methods sourced from library studies. In this study, it was found that the protection of privacy and personal data in Indonesia is still partial and sectoral which is different from GDPR that has specifically regulated in one bill. Big Data Analytics also has several implications with applicable privacy and personal data protection principles. Indonesia is advised to immediately ratify the provisions on protection of privacy and personal data which is now is still in the form of a RUU."

"ABSTRAK

Semakin strategisnya peran Direktorat Jenderal Bea dan Cukai (DJBC) Kementerian Keuangan Republik Indonesia dalam memfasilitasi perdagangan internasional membuat DJBC harus terus berinovasi dengan memanfaatkan teknologi mutakhir. DJBC dituntut untuk memberikan pelayanan yang efisien dan melakukan pengawasan yang efektif yang merujuk pada praktik-praktik terbaik dalam kepabeanan internasional. Implementasi Big Data pada DJBC bertujuan untuk mendapatkan manfaat dari data yang telah dikumpulkan agar dapat dianalisis untuk mendukung pengambilan keputusan. Konsep Smart Customs and Excise mengusung Big Data sebagai inti dari semua sistem dan proses bisnis pada DJBC, namun sampai dengan saat ini penerapan Big Data masih bersifat proof of concept. Penerapan teknologi baru tanpa adanya arah pengembangan yang jelas memiliki risiko kegagalan, untuk itu diperlukan evaluasi penerapan Big Data di DJBC. Pengukuran tingkat kematangan Big Data dapat digunakan sebagai langkah awal untuk menilai situasi yang sebenarnya dari sebuah organisasi, memperoleh dan memprioritaskan langkah-langkah perbaikan dan kemudian mengontrol setiap tahap pelaksanaannya. Hasil pengukuran kematangan Big Data dapat dijadikan sebagai acuan untuk merumuskan saran dan rekomendasi bagi DJBC untuk mencapai tingkat kematangan yang lebih tinggi. Pengukuran dilakukan menggunakan framework TDWI Big Data Maturity Model untuk mengevaluasi implementasi Big Data pada DJBC. Pengumpulan data dilakukan melalui wawancara pertanyaan tertutup, kemudian diolah menggunakan assessment tools. Hasil evaluasi menunjukkan bahwa tingkat kematangan Big Data pada DJBC ada pada tingkat 3 (Early Adoption) dari skala 1 - 5.

ABSTRACT

---

The more strategic role of the Directorate General of Customs and Excise (DGCE) of the Ministry of Finance of Republic of Indonesia in facilitating international trade has made DGCE to continue to innovate by utilizing the latest technology. DGCE is required to provide efficient services and conduct effective supervision that refers to international customs organization best practices. Implementation of Big Data on DGCE aims to get the benefits of the data that has been collected so that it can be analyzed to support decision making. The Smart Customs and Excise concept brings Big Data as the core of all systems and business processes in DGCE, but until now the implementation of Big Data is still proof of concept. Implementation of new technology without the direction of development that clearly defined has the risk of failure, therefore an evaluation is needed regarding the implementation of Big Data on DGCE. Measuring the maturity level of Big Data can be used as a first step to assess the actual situation of an organization, obtain and prioritize corrective steps and then control each stage of its implementation. The measurement results can be used as a reference to formulate suggestions and recommendations for DGCE to reach a higher maturity level. Measurements were made using the TDWI Big Data Maturity Model framework to evaluate the implementation of Big Data on DGCE. Data collection is done through closed question interviews, then processed using assessment tools. The evaluation results indicate that the maturity level of Big Data on DGCE is at phase 3 (Early Adoption) of scale 1 to 5. The results of the study provide recommendations on each dimension to be able to increase the maturity level to phase 4 (Corporate Adoption) with priority changes starting from the organizational dimension, analytics, data management, infrastructure, and governance.
