Judul: Optimasi pemasangan iklan di televisi dengan metode Integer Programing
Abstrak: Iklan merupakan dalah satu strategi pemasaran produk, mengingat pemasangan iklan di televisi memerluakn biaya yang cukup besar. Oleh karena itu diperlukan suatu metode untuk mendapatkan kombinasi spot iklan yang optimal dengan menggunakan biaya yang efisien dan efektif untuk dapat menjangkau target penonton yang diharapkan. Salah satu kriteria iklan dikatakan efektif jika memiliki jumlah nilai rating yang tinggi selama periode beriklan atau lebih dikenal dengan nilai Gross Ratingn (GRP) dan Reach N+ yang besar.

Judul: Penjadwalan Siaran Iklan pada Televisi Menggunakan Metode Integer Linear Programming dan Metode Heuristik
Abstrak: Scheduling commercial videotapes in broadcast television is a kind of scheduling problem in mathematical programming. This problem requires special rules in order to broadcast so that it produces an optimal schedule. Broadcasting company sells several slots that will be filled by the commercials to be broadcast. Broadcasting company schedules a number of commercials in a set of available slots such that multiple airings of the same commercial are as evenly spaced as possible. In this work we model scheduling commercial videotapes by using integer linear programming and provide exact and heuristics solutions. We illustrated our result by considering a scheduling problem which consist of 25 commercials from 9 different products.

Abstrak: I reevaluated taxonomic of subgenus Papurana position from Halmahera based on morphological and molecular analyses. My results show that two separate species occur on the Halmahera Island, each nested within two distinct clades (hereafter papua clade and celebensis clade), one of which corresponds to H. moluccana (celebensis clade) and the other to an unidentified species (papua clade). By p-distance ranging from 6.9 to 11.5% on the 16S rRNA gene, the unidentified species (Hylarana sp.) is genetically different from all congeners of the papua clade. The Hylarana sp. can be distinguished from all congeners by following combination of charactes: vomer teeth in two oblique rows with narrow inter-vomer distance; snout rounded dorsally; dorsum with few scattered cone-shaped tubercles that are black with white tips; distinct skin folds (ridges) on the dorsal side of the thigh coinciding with dark brown cross bars; a marbled pattern on the ventral side of the thigh and yellowish groin. I also present new data for H. daemeli, H. volkerjane, and H. arfaki from the western region of Papua. Furthermore, I found that H. celebensis has numerous mtDNA lineages, indicating cryptic diversity within the celebensis clade. The discovery of two separate species on Halmahera necessitates more research into the biogeographic history of Hylarana in Northern Moluccas.
