Judul: Distribusi Spasial Zooplankton di Perairan Pesisir Kabupaten Tangerang
Abstrak: Zooplankton is important component in marine food chain. The observation was conducted in the coastal waters of Tangerang with the purpose to provide information regarding the spasial distribution of zooplankton and its relation to the water quality which is presumed to be affected by material input from several nearby rivers. During research there were found 12 groups of zooplankton which consist of Protozoa, Rotifera, Crustacea, Ctenophora, Chaetognata, Urochordata, Nematoda, larvae of Coelenterata, larvae of Echinodermata, larvae of Gastropoda, larvae of Polychaeta, and larvae of Pelecypoda. The spasial distribution of zooplankton showed that zooplankton separated into two locations: location 1 (Kronjo, Mauk, Rawa Saban, and Tanjung Pasir Station) and location 2 (Dadap Station). The water quality of Tangerang Coastal Waters was proper for optimum life of zooplankton. Ammonia and salinity indicated to be more influence towards the distribution of zooplankton in the coastal waters of Tangerang Regency.

Judul: Distribusi Zooplankton Dan Keterkaitannya Dengan Kelimpahan Fitoplankton di Perairan Teluk Lampung
Abstrak: Penelitian ini bertujuan untuk mengetahui distribusi zooplankton dan keterkaitannya dengan kelimpahan fitoplankton di perairan Teluk Lampung. Penelitian dilakukan dengan metode survei berkenaan dengan distribusi zooplankton baik secara spasial maupun temporal. Pengambilan contoh dilakukan sebanyak 4 kali dari bulan Januari-Juli 2001. Lokasi pengamatan terdiri dari 11-14 stasiun, pada lapisan permukaan dan kedalaman 5 meter. Parameter yang diamati meliputi kelimpahan zooplankton dan fisika-kimia (suhu, salinitas, kecerahan, kekeruhan, oksigen terlarut) yang merupakan data primer serta kelimpahan fitoplankton yang merupakan data sekunder. Analisis data yang digunakan meliputi indeks keanekaragaman Shannon-Wiener, indeks keseragaman Evennes, indeks dominansi Simpson, indeks dispersi Morisita, anal isis ragam klasifikasi dua arah, dan anal isis regresi linear berganda antara Crustacea (Y) dengan fitoplankton (Bacillariophyceae = Xl, Dinophyceae = X2, dan Cyanophyceae = X3). Hasil penelitian mencakup struktur komunitas (komposisi dan kelimpahan, keanekaragaman, keseragaman, dan dominansi zooplankton), distribusi zooplankton (pola dan distibusi spasial-temporal), keadaan habitat (fitoplankton dan parameter fisikakimia), serta hubungan antara zooplankton dengan fitoplankton.

Judul: Perbandingan Metode Ekstraksi Ciri FFT, PCA, dan FPE dalam Pengenalan Karakter Tulisan Tangan
Abstrak: The main purpose of this research is to create a fully functioned system to translate any handwritten mathematic expression into LaTeX code. This research itself serves as one of the basic part of the system, the handwritten character recognition system. Three feature extraction methods were compared and evaluated. They are Feature Point Extraction, Principle Components Analysis, and Fast Fourier Transform. Classification method used in this research is K-Nearest Neighbors. Accuracy measurement of the three methods shows that the maximum accuracy score by Feature Point Extraction is around 26%, while Principle Component Analysis and Fast Fourier Transform score is approximately 60% and 70%, respectively. FPE, despite its high score on optical character recognition (around 86% accuracy score), did not perform well due to the fact that the FPE method used in this research did not aware of the position of each feature point. PCA and FFT proved to be better for handwritten character recognition, with FFT being the one to have the highest accuracy score.
