Judul: Optimization of allocation legislative seats at the ri parliament in the 2014 election
Abstrak: Pengalokasian kursi legislatif merupakan salah satu tahapan terpenting pada pelaksanaan pemilihan umum. Ada dua tahap pengalokasian kursi legislatif di Indonesia, yaitu pengalokasian kursi daerah pemilihan dan partai. Kedua tahapan ini diformulasikan sebagai model pemrograman linear integer. Model ini bertujuan untuk meminimumkan deviasi antara kursi yang didapat dengan kursi yang seharusnya didapat oleh daerah pemilihan dan partai. Dengan menggunakan software LINGO 11.0 dihasilkan pengalokasian kursi partai di setiap daerah pemilihan. Di sini, metode kesetaraan suara menghasilkan nilai objektif yang lebih kecil dibandingkan metode perimbangan wajar. Pada tahap pengalokasian kursi untuk setiap partai, metode kuota termodifikasi menghasilkan nilai objektif yang lebih kecil dibandingkan metode Hare quota, metode Droop quota, metode imperiali quota, dan metode party block vote. Tetapi dengan menggunakan metode kesetaraan suara, nilai objektif dari alokasi kursi partai tidak selalu lebih kecil daripada menggunakan metode perimbangan wajar. Kata kunci: alokasi kursi legislatif, metode kuota, metode party block vote, pemrograman linear integer, Allocation of legislative seats is one of the most important stages in the general election. There are two stages in the allocation of legislative seats in Indonesia, namely district and party seats allocation. Both stages are formulated via integer linear programming model. The objective of the model is to minimize the deviation between the seats obtained and the seats that should be obtained of district and party. In this work, LINGO 11.0 software was used to determine the party seats allocation for each district. Here, the method of equality of votes has an objective value smaller than that of the reasonable balance method. For the party seats allocation, modified quota method has an objective value smaller than that of the Hare quota method, Droop quota method, imperiali quota method, and party block vote method. But, with using method of equality of votes, objective value of party seat allocation not always smaller than that using reasonable balance method.

Judul: Analisis Spasial untuk Sebaran Suara dan Perolehan Kursi Partai Politik pada Pemilu Legislatif 2009 di Wilayah DKI Jakarta dan Jawa Barat
Abstrak: In terms of election, voters behavior within a certain area varies widely and produces various responses of party preferences. This thing indicates that there is an influence of spatial on voters’ preferences besides other variables and factors innate in every individual. What is interesting is that in legislative contest, changes in districts as a spatial factor that can result in different vote accumulations that can impact different seat gain. Therefore there is a deterministic technical aspect to be emphasized which are the technical mechanism and regulations of district creation. This research used Local Indicator Spatial Association (LISA), statistical method based on Local Moran Index, to prove the influence of those two factors on the result of party votes and seats in the Election of 2009.

Judul: Aktivitas Antimikrob dan Karakterisasi Nanosilver Ekstraseluler Veronaea sp. KT19
Abstrak: Synthesis of nanosilver biologically may use fungi. The purpose of this study was to characterize and to determine antimicrobial activity of extracellular nanosilver of Veronaea sp. KT19. The highest activity was shown by extract of day 6 with diameter of inhibition zones on the Escherichia coli was 15.5±0.7 mm and Bacillus subtiliswas 13±2.8 mm. Spectrum of the nanoparticles of A6, A12, B6 (x), B6 (y), B12 (x), and B12 (y) was measured at a wavelength of 450 nm, 400 nm, 263.5 nm, 262 nm, 262.5 nm and 256.5 nm. The smallest particle size average obtained by A6 was 32.25 nm. Antimicrobial activity against 5 microorganisms showed weak activity againts Bacillus subtilis and Staphylococcus aureus, showed moderate activity againts Escherichia coli, Pseudomonas aeruginosa and Candida maltosa.
