Karakteristik Morfometrik dan Produksi Telur Itik di Sentra Peternakan Itik Kabupaten Tolitoli

This research aimed to identify the morphometrics characteristic and egg production of duck in the center farming area in Tolitoli Regency. There are four districts chosen as the research sample location, which are Dampal Selatan, Lampasio, Galang, and Dako Pemean. In each district, 250 female ducks were used. Parameters was observed is body weight, body length, pubis width, shank length, chest circumference, wings length, neck length, and egg production based on Hand Day Production. The correlation between morphometrics and HDP analyzed by IBM Statistic 25 software. The results showed that pubis width have a strong positive correlation with egg production (r value 0.37 – 0.45). The body weight have negative correlation with HDP (-0.31 to -0.22), chest circumference (-0.13 to -0.05), body length (-0.01 to 0.03), wing length (-0.12 to 0.03), neck length (-0.03 to 0.02), and shank length (0.02 to 0.03). The morphometrics characteristic and egg production in duck center farming area are uniform with an HDP at 63%. Keywords: Correlation; Duck; Egg; Morphometrics; Production Abstrak Penelitian ini bertujuan untuk mengetahui karakteristik morfometrik dan produksi telur itik di sentra peternakan itik Kabupaten Tolitoli. Terdapat empat kecamatan yang dijadikan lokasi sampel pada penelitian ini yaitu Kecamatan Dampal Selatan, Lampasio, Galang, dan Dako Pemean dijadikan sampel penelitian. Masing-masing 250 itik betina yang digunakan. Parameter yang diamati yaitu bobot badan, panjang badan, lebar pubis, panjang shank, lingkar dada, panjang sayap, dan panjang leher serta produksi telur berdasarkan Hen Day Production (HDP). Hubungan morfometrik dengan produksi telur dianalisis menggunakan analisis korelasi menggunakan IBM Statistic 25. Hasil penelitian menunjukkan bahwa lebar pubis memiliki korelasi yang positif dan cukup kuat dengan HDP dengan nilai korelasi antara 0,37–0,45. Bobot badan berkorelasi negative dengan HDP (-0,31 sampai -0,22), lingkar dada (-0,13 sampai -0,05), panjang badan (-0,01 sampai 0,03), panjang sayap (-0,12 sampai 0,03), panjang leher (-0,03 sampai 0,02), dan panjang shank (0,02 sampai 0,03). Karakteristik morfometrik dan produksi telur itik pada sentra peternakan yang diteliti seragam dengan nilai HDP sebesar 63%. Kata kunci: Itik; Korelasi; Morfometrik; Produksi; Telur

Isolation and selection of nitrite metabolising bacteria from the bottom mud of lobster culture area in Xuan Dai bay, Phu Yen province

The study had isolated and selected groups of bacteria that metabolise nitrite from the bottom mud of lobster cages in Xuan Dai bay, Phu Yen province. Analysis results from 21 sludge samples taken from 11 cages of lobster farming area isolated 16 strains of bacteria capable of nitrite metabolism. After investigating biological characteristics and nitrite metabolism of bacteria strains, 10 strains of bacteria were collected with the ability to metabolise nitrite over 95% in 72 hours. In addition, 10 strains of bacteria with the highest NO2- treatment efficiency, identified by genetic analysis and looked up on BLAST, defined as Stenotrophomonas pavanii, Chryseobacterium gleum, Stenotrophomonas maltophilia, Delftia lacustris, Acinetobacter junii

Pemanfaatan Tanah Kas Desa Tatung Kecamatan Balong Kabupaten Ponorogo Dengan Sistem Lelang Tanah

Town resources can be as Town depository lands, standard land, town markets, creature markets, boat moorings, town structures, fish barters, farming item barters, town claimed woods, town springs, public showers, and different resources having a place with the Town people group. Town land is town possessed land that can be utilized for town pay and for the government assistance of the town local area. This examination was directed to perceive how the utilization of town depository lands and the interaction of land closeout in Tatung Town, Balong Ponorogo Region. Questions that emerge in this investigation are the manner by which the Tatung Town Government, Balong Locale, Ponorogo Rule oversees town depository grounds and how the land sell off measure in Tatung Town Balong Region, Ponorogo Rule. This examination utilized a subjective graphic exploration strategy. The land closeout framework in Tatung Town, Balong Locale, Ponorogo Rule can improve the way of life of the Town people group where with the town depository land sell off framework, individuals who don't have farming area can oversee land, yet the sale interaction has not been done such that right and open so lawful issues don't emerge later on and there is no maltreatment of force and authority by the town government, so in the town of Tatung there is a requirement for socialization and heading to the local area and town government in regards to the right land sell off measure.
