Judul: Optimization of Technical Indicators Based on Genetic Algorithm in Stock Exchange.
Abstrak: Stock trading is become popular in Indonesia. The generation of profitable trading rules for stock exchange investments is a difficult but popular problem. The use of Machine Learning in this problem is to obtain objective results by using information in the past market behavior. In this research, genetic algorithm is used to automatically generate trading rules based on Technical Indicators. The method in this research used Hirabayashi (2009) model and also modification model of Hirabayashi by adding 2 additional technical indicators. The results shows that Hirabayashi Model and Modification Model generate better profit result compare with buy and hold strategy in small capitalization stock or big capitalization stocks in Indonesian Stock Exchange. By using Genetic Algorithm, some of the technical indicators could be ignored. It’s also found that modification model could adapt the price trend better than Hirabayashi Model.

Judul: Pembentukan Portofolio Reksadana Saham yang Optimal Menggunakan Algoritma Genetika Multi Objektif
Abstrak: Investments in financial assets has become a trend in the era of globalization, especially the investment in mutual fund shares. Investors who want to invest in stock mutual funds can set up an investment portfolio in order to generate an maximal return and minimimal risk. In this study the author used the Multi-Objective Genetic Algorithm Non-Dominated Sorting II (MOGA NSGA-II) technique with the Markowitz portfolio principle to find the best portfolio from several mutual funds. The data used are 10 company stock mutual funds with a period of 12 months, 24 months and 36 months. The genetic algorithm parameter used are probability crossover of 0.65, probability mutation of 0.05, Generation 400 and a population numbering 20 individuals. The study produced a combination of the best portfolios in the period of 24 months with a computing time of 63.289 seconds.

Judul: Feline Panleukopenia Pada Kucing
Abstrak: Feline Panleukopenia adalah salah satu penyakit yang menyerang hewan kucing. Bersifat sangat menular, akut, terkadang fatal, dengan angka kematian yang tinggi pada populasi hewan rentan. Disebabkan oleh virus golongan Parvo yang sangat stabil dan tahan terhadap pengaruh lingkungan dan zat-zat kimia tertentu. Memasuki tubuh hewan rentan dengan cara peroral, inhalasi, parenteral, atau kontak langsung deng- an hewan sakit, lingkungan, bahan, dan alat yang terce mar. Virus penyebab mempunyai affinitas yang tinggi ter- hadap sel-sel yang intinya sedang aktif bersintesa dan berkembang biak. - Masa inkubasi berkisar antara dua sampai enam hari, kadang-kadang sampai sembilan hari. Gejala klinis yang tampak mulai dari kelemahan, anoreksia, tidak mau minum, depresi, demam biphasic, muntah-muntah, diare, dehidrata- si, kadang-kadang ataksia. Aspek patologi klinis yang paling khas adalah terjadinya panleukopenia yang sangat drastis. Kekebalan maternal banyak diturunkan oleh induk me lalui kolustrum. Kekebalan pasif ini cukup untuk melin dungi anak-anak kucing dari serangan virus penyebab serta sekaligus menghambat kekebalan aktif oleh tubuh,
