Judul: Pemanfaatan Twitter pada Penerapan Pendugaan Area Kecil dalam Pendugaan Elektabilitas Calon Gubernur Provinsi Jawa Tengah
Abstrak: Suatu survei dirancang untuk menduga elektabilitas calon gubernur Provinsi Jawa Tengah pada tingkat provinsi. Ukuran contoh pada kabupaten/kota sedikit atau bahkan tidak ada. Sedikitnya ukuran contoh dapat menyebabkan nilai dugaan elektabilitas tidak presisi. Pendugaan area kecil dapat mengatasi masalah tersebut tanpa meningkatkan ukuran contoh. Terdapat dua hal yang dibutuhkan dalam pendugaan kecil yaitu model area kecil dan informasi dari luar survei. Elektabilitas diduga secara tidak langsung menggunakan model area kecil. Modifikasi model dilakukan pada pendugaan tidak langsung elektabilitas kabupaten/kota yang tidak ada contonnya. Informasi dari luar survei yang digunakan berasal dari media sosial Twitter serta data dari pilkada dan pilgub periode sebelumnya. Twitter diidentifikasi untuk menyediakan informasi tambahan yang bisa didapatkan dan layak digunakan. Kuadrat tengah galat (KTG) dugaan elektabilitas diduga menggunakan metode resampling. Pendugaan elektabilitas pada tingkat provinsi untuk pendugaan langsung maupun tidak langsung memiliki presisi yang sama, namun pendugaan tidak langsung memiliki keunggulan mampu menduga elektabilitas pada tingkat kabupaten/kota.

Judul: Pendugaan Perolehan Suara Level Kabupaten/Kota pada Pemilihan Gubernur Jawa Barat Tahun 2013
Abstrak: Quick count is a method for verification of election results by estimating them from samples of the polling stations. Based on quick count simulation, direct estimation of election result at the level of subpopulations, for example at the county or city level on governor election, has greater risk of error in a relatively small sample size. One of the alternative methods for solving this problem is indirect estimation approach using small area estimation (SAE). This research applied direct estimation and SAE method to estimate proportion of election results in 2013 West Java governor election. Generalized linear mixed models (GLMM) approach of SAE is choosen since the data which were used to calculate the proportion is count data. The results show, the SAE generally better than direct estimation for relatively small sample size by MSE criterion.

Abstrak: S. Supramana, S. A. Lewis,.J. D. Mueller, B. A. Fortnum, and R. E. Ballard. 2001. Biology of Columbia lance nematod. ~ (Hoplolaimus columbus Sher) on soybean excised root culture. Nematropica 31 :283-2~)O. Feeding, egg development and oviposition, embryology, and postembtyonic development or Hoplolaimus col'lmbuswere observed on soybean (cultivar Hutcheson) excised root culture in Gam borg's B5 medium (pH 5.7,1.3% agar). Petri plate sterile cultures were placed inverted on a heated microscope stage (30°C) and observations were conducted using a color video camera and a time lapse digital videoca:;sette recorder. Oocytes were obsetved in each gonad 38 hours after feeding commenced and all egg possessing a terminal stalk was laid 96 hours later. Eggs were deposited it, the one-celled stag~ and a total of 217 hours (9 days) was required for a"newly laid egg to develop into a hatching second-stage juvenile at 30°C. Postembryonic development consisted of threejuvenile stages and an adult female with prior feeding occurring before molts and oviposition. The nematode fed ectoparasiticallyon the subepidermal cells and endoparasitically in the cortex and outer vascular tissue and remained at the infection site for 2·9 days. Key words: Columbia lance nematode, embryology, excised root culture, feeding behavior, HOfilo{aimus columbus, life cycle, oviposition, postembryonic development, soybean.
