Judul: Effect of zeolite supplemented on feed on kampung performances
Abstrak: Zeolit adalah mineral yang memiliki struktur berongga yang dapat menyerap molekul lain. Penggunaan zeolit dapat meningkatkan efisiensi pakan dan mengurangi kelembaban litter dengan menghambat pertumbuhan dan kerja mikroorganisme. Berdasarkan kemampuannya, zeolit dapat digunakan dalam pakan ayam. Penelitian ini bertujuan untuk menguji efek dari zeolit terhadap performa ayam kampung. Penelitian ini menggunakan 320 ekor ayam kampung yang dipelihara selama enam minggu dan dibagi menjadi 16 kandang masingmasing berisi 20 ekor ayam kampung. Analisis data yang digunakan dalam penelitian ini adalah rancangan acak lengkap (RAL). Taraf penggunaan zeolit yang digunakan adalah 0%, 0.5%, 1.0% dan 1.5%, masing-masing dengan 4 ulangan dan 20 ekor kampung per unit percobaan. Peubah yang diukur adalah pertambahan bobot badan harian, konsumsi ransum harian, konversi pakan dan mortalitas. Data dianalisis menggunakan metode analisis ragam (ANOVA). Hasil menunjukkan bahwa penambahan zeolit hingga taraf 1.5% tidak berpengaruh nyata terhadap konsumsi ransum harian, pertambahan bobot badan harian dan konversi ransum., Zeolite are minerals that have a hollow structure that can absorb other molecules. The use of zeolite can improve feed efficiency and reduce litter moisture content by inhibiting microbial growth and development. Based on their ability, zeolites therefore can be used in chicken feed. This study aims to assess the effect of zeolite supplemented feed on kampung chicken performances. This research used 320 kampung chickens which were kept for six weeks and divided into 16 cages (each containing 20 kampung chickens). The experimental design used in this study was a completely randomized design (CRD). The addition of zeolites used were 0%, 0.5%, 1.0% and 1.5%, with 4 repetitions (20 chickens/experimental unit). The variables measured were daily feed consumption, daily gain, feed conversion ratio and mortality. Data was analyzed by analysis of variance (ANOVA) methods. The result showed that the addition of zeolite to the extent of 1.5% had no significant difference for the daily feed consumption, daily gain and feed conversion ratio.

Judul: Persentase Karkas Ayam Kampung Hasil Penambahan Zeolit dalam Ransum
Abstrak: Kampung chicken is one of the main animal protein contributor in Indonesia. The high demand for chicken meat must be supported by an increase in its productivities. Zeolite is a mineral derived from alkali metals and alkaline soil that are easily found around the area of the volcano. Zeolites can be used as an additive in livestock rations. This study aims to determine the productivity of kampung chicken meat as a result of the addition of zeolite in the ration. A total of 64 kampung chickens were selected from a population of 320 kampung chickens used in this study that were divided into 4 treatments and 4 replications (4 kampung chickens). R1, without the addition of zeolite ration R2, ration with the addition of 0.5% zeolite R3, ration with the addition of 1% zeolite and R4, ration with the addition of 1.5% zeolite. Parameters measured were weight of chicken that had been fasted for 8 hours, carcass weight and carcass percentage of chicken, litter moisture content, and Income Over Feed, Chick and Zeolite Cost (IOFCZC). The results showed that addition of zeolite in the diet did not significantly affect (P>0.05) to slaughter weight, carcass weight and carcass percentage of chicken, and litter moisture content. The highest income earned the addition of zeolite of 1.5 kg per 100 kg ration (R3) was Rp8 873.81.

Judul: Jaringan Syaraf Tiruan Untuk Pengenalan Tanda Tangan
Abstrak: Penelitian ini mengformulasikan masalah pengenalan tanda tangan menggunakan jaringan syaraf Tiruan (JST) melalui tiga representasi pola input JST, yaitu representasi biner, bipolar dan kontinu. Teknik JST yang digunakan adalah propagasi balik yang memiliki arsitektur multi layer neural network dengan satu lapisan tersembunyi. Data tanda tangan diperoleh dari 10 orang berbeda yang berupa data tanda tangan kasar (raw signature image) tanpa ekstraksi ciri tanda tangan. Selain itu juga digunakan metode pembelajaran lain yang ada di dalam Matlab, yaitu metode pembelajaran radial basis function.sebagai pembandingan. Dalam hal ini, JST yang digunakan adalail Probabilistic Neural Networks (PNN).
