Judul: Analisis keragaan konsumsi ikan di Indonesia tahun 2005 - 2011
Abstrak: The objective of this study was to analyze fish consumption in Indonesia 2005–2011. The design of this study was the descriptive study. Data used in this study was secondary data based on national social and economic survey (SUSENAS). The study showed average national actual fish consumption 26,04 kg/capita/year, average rural actual fish consumption 25,69 kg/capita/year and average urban actual fish consumption 26,51 kg/capita/year. Average growth rate of national fish consumption is 0,05% per year. Average growth rate of rural fish consumption is -0,05% per year. Average growth rate of urban fish consumption is 0,37% per year. The group of fish that consumed the most is fresh fish (62%) and the less is cooked food (10%). Average national fresh fish consumption is 16,16 kg/capita/year. Average rural fresh fish consumption is 15,74 kg/capita/year. Average urban fresh fish consumption is 16,71 kg/capita/year. Fish consumption from prepared fish is higher in rural (32%) tahunan urban area. Average national prepared fish consumption is 7,25 kg/capita/year. Average rural prepared fish consumption is 8,30 kg/capita/year. Average urban prepared fish consumption is 6,39 kg/capita/year. Fish consumption from cooked food is higher in urban (14%) than rural area. Average national fish consumption from cooked food is 2,63 kg/capita/year. Average rural fish consumption from cooked food is 1,65 kg/capita/year. Average urban fish consumption from cooked food is 3,71 kg/capita/year. Low expenditure group consumed fish lower than high expenditure group. Ideal fish consumption is 32,7 kg/capita/ year or 12,9 gram protein/capita/day.The sufficiency of fish is projected 8,10 million tons at 2015.

Judul: Analisis permintaan produk perikanan di indonesia: suatu studi cross-sectional
Abstrak: Tulisan ini bertujuan untuk menganalisis pola konsumsi dan kontribusi produk ikan terhadap pola konsumsi penduduk, menganalisis faktor-faktor yang mempengaruhi permintaan produk ikan penduduk Indonesia, menduga elastisitas harga dan pendapatan beberapa kelompok ikan, serta merekomendasikan opsi kebijakan yang diperlukan untuk mendukung peningkatan konsumsi ikan masyarakat Indonesia berdasarkan proyeksi tingkat konsumsi ikan. Data yang digunakan adalah data SUSENAS 2008 modul konsumsi rumahtangga Indonesia yang dilakukan oleh Badan Pusat Statistik. Jenis ikan yang dianalisis adalah kelompok ikan segar, ikan awetan, udang/hewan lain yang segar dan udang/hewan air lain yang diawetkan. Variabel wilayah perdesaan/perkotaan, serta jumlah anggota rumah tangga diperhitungkan pula dalam penelitian ini. Metode multistage budgetting approach dengan model QUAIDS (Quadratic Almost Ideal Demand System) digunakan dalam penelitian ini. Hasil analisis menunjukkan bahwa sebagian besar penduduk Indonesia di berbagai wilayah lebih banyak mengkonsumsi ikan segar daripada ikan awetan maupun udang. Konsumsi ikan segar tertinggi adalah di wilayah Sulawesi dan Maluku, terendah di Pulau Jawa, baik di perkotaan maupun perdesaan. Tingkat konsumsi ikan segar dan udang segar di perkotaan secara umum lebih tinggi daripada di perdesaan. Harga ikan segar di seluruh wilayah Indonesia relatif cukup seragam. Harga ikan segar dan ikan awetan lebih tinggi dibandingkan dengan harga udang segar dan udang awetan. Harga udang segar dan udang awetan terlihat tidak berbeda jauh, namun variasinya cukup tinggi. Harga termahal adalah di wilayah Kalimantan Tengah, kemudian Kalimantan Selatan, Bangka Belitung dan Aceh, sedangkan harga terendah adalah di wilayah Daerah Istimewa Yogyakarta, Jawa Tengah dan Bali. Dari alokasi pengeluaran untuk makanan (sekitar 49 persen), 7.9 persen diantaranya dialokasikan untuk konsumsi ikan. Alokasi anggaran untuk ikan di Indonesia paling banyak digunakan untuk konsumsi ikan segar (55 persen) dan ikan awetan (40 persen). Alokasi anggaran yang digunakan untuk konsumsi udang segar hanya 4 persen, sedangkan untuk udang awetan hanya 1 persen. Pada kelompok ikan segar, udang/hewan air yang segar, dan udang/hewan air awetan terlihat bahwa semakin tinggi tingkat pendapatan, semakin besar share pengeluaran untuk ketiga komoditas tersebut. Sedangkan pada kelompok ikan awetan terjadi sebaliknya, semakin besar tinggi tingkat pendapatan semakin rendah share pengeluarannya.

Judul: Application of Mel Frequency Cepstrum Coefficients (MFCC) as Feature Extraction on Phoneme Recognition with Probabilistic Neural Network (PNN) as Classifier
Abstrak: Voice recognition (speech recognition) is one field of study in voice processing. This technology can convert voice signals into a form of written information (text). With this technology, people can interact with a computer. MFCC feature extraction computes the cepstral coefficients by considering the human hearing. This research is a phoneme recognition using feature extraction MFCC and PNN as feature matching model. This study compares the coefficient, overlap, and the test data without noise and with noise. MFCC is used with 13, 20, 26 coefficients and 0%, 25%, 50% overlap. Noise is added by 30 dB, 20 dB and 10 dB. From the comparison of the three overlaps, produced the best accuracy at 50% overlap with an accuracy of 94,71%. From comparing the three coefficients, better accuracy resulting in coefficients of 20 and 26 with an accuracy of 97,12% at 50% overlap. After comparing between the coefficients of 20 and 26 with overlap of 25% then the coefficient 26 is obtained that better accuracy of 94,23%. This shows that in this study the coefficient 26 is the best. In this research, there are three noise variables. The variables are 10 dB, 20 dB, and 30 dB. The best accuracy reached when the noise variable is 30 dB rather than 10 dB or 20 dB because the accuracy has the closest accuracy compared by the accuracy when noise was not added into the data. When the noise variable is 30 dB, the percentage of accuracy is 85,3%.
