Analisis Big Data untuk Intervensi Kesehatan Masyarakat

Selasa (25/4/2017), Departemen Biostatistika dan Kependudukan Fakultas Kesehatan Masyarakat Universitas Indonesia (FKM UI) menyelenggarakan Kuliah Umum Big Data dengan tajuk “Big Data Analysis for Public Health Intervention” di Ruang Promosi Doktor, FKM UI.

Kuliah umum ini bertujuan untuk memberikan pengenalan terkait big data, konsep bisnis analis, pemanfaatan big data dalam bidang kesehatan masyarakat dan penelitian di bidang kesehatan masyarakat, serta pengenalan aplikasi dalam pengolahan big data.

Kuliah umum menghadirkan dua pembicara yang ahli dalam bidang ini yakni dr. Iwan Ariawan, MSPH, yang merupakan lulusan Master of Science in Public Health dari University of California, Los Angeles dan merupakan Staf Pengajar Pemodelan Statistik dan Manajemen Data dengan Komputer di FKM UI serta Dr. Herwanto, S.Kom, M.Si, yang merupakan IT Manager di PT Pertamina Bina Medika, dan dimoderatori oleh Dr. Besral, SKM, M.Sc yang merupakan Ketua Departemen Biostatistika dan Kependudukan FKM UI.

Dr. Herwanto, S.Kom, M.Si, yang menjadi pembicara pertama dalam kuliah umum kali ini memberikan materi terkait “Big Data Analytics: Tools dan Aplikasinya”. Sebagai seorang praktisi ia menjelaskan secara aplikatif bagaimana penggunaan tools dan aplikasi dalam pengolahan big data.

Di dalam materinya, Herwanto menjelaskan bahwa big data merupakan istilah untuk data sangat besar dan kompleks yang tidak dapat dikelola (capture, store, manage, analyze) dengan software dan tool pemrograman database biasa/konvensional. Selama ini, analisis data biasanya hanya mengenal suatu software tertentu hanya digunakan untuk satu jenis data saja, tetapi dalam kuliah umum Herwanto menjelaskan cara penggunaan Hadoop suatu aplikasi yang dapat digunakan untuk mengolah data numeric, teks, dan image sekaligus.

Sementara dalam sesi materi kedua, dr. Iwan Ariawan, MSPH menyampaikan materi terkait “Pemanfaatan Big Data dalam Kesehatan Masyarakat”. Pendekatan kesehatan masyarakat sudah sejak lama memanfaatkan data. Mengumpulkan data tentang kejadian yang sudah terjadi dan membuat kesimpulan berdasarkan pola yang ada pada data tersebut.

Menurut dr. Iwan, dalam kesehatan masyarakat kita terutama tertarik terhadap perilaku dan perubahan perilaku dari masyarakat, institusi kesehatan, tenaga kesehatan dan politisi. Ketersediaan data yang besar dan cepat dari segala sumber merupakan alat yang bermafaat untuk kesehatan masyarakat. Tetapi, ketersediaan big data juga memberikan tantangan tersendiri dalam pemanfaatannya.

Tantangan pemanfaatan big data dalam Kesehatan Masyarakat ini antara lain ketersediaan dan akses data, struktur dan klasifikasi data, privasi dan kerahasiaan data perorangan, serta bias dalam analisis faktor risiko. Sehingga para pelaku profesi Kesehatan Masyarakat harus berhati-hati dalam menggunakan big data.

Pada akhir kuliah umum, moderator menyimpulkan bahwa jumlah data yang telah dibuat dan disimpan pada tingkat global hari ini hampir tak terbayangkan jumlahnya. Data tersebut terus tumbuh tanpa henti. Sayangnya sampai saat ini, baru sebagian kecil data yang telah dianalisis. Pentingnya big data, tidak hanya seputar pada jumlah data yang di miliki, tetapi hal yang penting adalah bagaimana mengolah data-data tersebut untuk pengambilan keputusan.

Estimating Numbers of Orphans and Vulnerable Children – A Test of Regression Modeling

An earlier study reported a tight linear fit between national adult HIV prevalence and the percentage of children living in a household with at least one HIV-positive adult. MEASURE Evaluation extended this analysis to all existing DHS data sets with HIV testing, to determine the feasibility of using regression modeling to estimate the size of two priority groups: (1) children living with at least one adult who is HIV-positive, and (2) orphans and coresident children living with at least one adult who is HIV-positive.

At the national level, we found reasonably tight linear relationships between HIV prevalence among adults and the proportion of children living with at least one HIV-positive adult and between adult HIV prevalence and the proportion of orphans and coresident children living with at least one HIV-positive adult. However, at the subnational level, owing to small sample sizes, we found greater variation at the same level of HIV prevalence in the proportion of children living with an HIV-positive adult. Although the slopes and intercepts of the national and subnational regression lines are almost the same, the confidence intervals for the subnational level estimates are very wide and many data points fall outside the prediction.

PEPFAR has given priority for OVC programs to 21 countries. Of these, 17 have a recent biomarker survey: Burundi, Cameroon, Cote d’Ivoire, Democratic Republic of Congo, Ethiopia, Haiti, Kenya, Lesotho, Malawi, Mozambique, Namibia, Rwanda, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. For these countries, we recommend using the results of our secondary DHS analyses for programmatic estimates. Our Excel workbook (OVC estimates from DHS, available here: includes point estimates and 95-percent confidence intervals at both the national and subnational levels of the proportions of children who live in a household with an HIV-positive adult and the proportion of children who are orphans or coresident children living in a household with an HIV-positive adult, and extrapolates the observed proportions to numbers of children.

At present, four countries in the PEPFAR OVC portfolio do not have a recent DHS survey with HIV testing: Botswana, Nigeria, South Africa, and South Sudan. For these countries, the linear regression is a reasonable way to estimate at the national level the proportion of children who live in a household with an HIV-positive adult and the proportion of children who are orphans or coresident children living in a household with an HIV-positive adult. We have created an Excel workbook to predict these two indicators at the national level and to extrapolate the predicted proportions to numbers of children (OVC estimation calculator, available here:


Integrasikan Jaringan Telekomunikasi, UI Jalin Kerja Sama dengan PT JPI

Jumat, (31/3/2017) di ruangan Rapat A Pusat Administrasi Universitas (PAU) PT. Jaringan Pintar Indonesia (JPI) menandatangani perjanjian kerja sama dengan UI dalam hal jasa telekomunikasi.

Perjanjian ini diadakan dalam rangka mengintegrasikan seluruh jaringan provider yang bekerja sama dengan UI dalam satu wadah.

“Ini dalam rangka efektifitas dan efisiensi. Nanti jadinya kami bila ingin mengatur provider-provider ini hanya cukup menghubungi pihak JPI, tidak perlu satu-persatu ke providernya,” ungkap Dr. Ir. Dodi Sudiana M.Eng, Direktur Kerjasama UI.

Selain itu, rencananya juga akan dibangun micro cell di UI dalam rangka meningkatkan area coverage jaringan telekomunikasi di UI.

Microcell adalah seperangkat pemancar yang digunakan dalam menambah kapasitas jaringan di daerah dengan tingkat penggunaan telepon yang sangat padat, seperti stasiun kereta api, mall, ataupun area perkantoran.

Microcell juga dipergunakan untuk mendukung teknologi 4G LTE yang membutuhkan kapasitas data yang sangat lebar dan tanpa putus.

“Tujuan besarnya adalah tidak ada lagi area di UI yang tidak terjangkau jaringan internet,” tambah Dodi
