Abstract

Kolam air panas War Aremi, adalah kolam Air Panas yang terdapat di Kampung Matatun Distrik Kebar, Papua Barat. Bakteri Termofilik tumbuh pada suhu lebih dari 45oC. Bakteri Termofilik menghasilkan enzim yang bermanfaat dalam dunia industri. Penelitian ini merupakan penelitian eksploratif yang bertujuan untuk mengisolasi bakteri termofilik dari Kolam Air Panas War Aremi di Kampung Matatun, Distrik Kebar, Kabupaten Tambrauw, Papua Barat dengan menngunakan Metode Tuang (Pour Plate) Dari hasil penelitian diperoleh tiga isolat bakteri termofilik dari sampel air panas, dan 4 isolat dari sampel sedimen. Berdasarkan hasil pengecatan gram dan pengamatan morfologi sel, ketujuh isolat bakteri termofilik yang berhasil diisolasi adalah merupakan kelompok bakteri gram positif dengan morfologi sel berbentuk sel batang. Berdasarkan hasil pewarnaan gram, pengamatan morfologi sel dan karakterisasi biokimia, ketujuh isolat bakteri termasuk genus Bacillus.

Abstract

The first time sperm production experienced by a man as an early sign of gonadal maturity (spermarche) is still considered taboo and violates ethics to be discussed in public. As a sign of sexual maturity, the age at spermarche varies among individu and population. This study aims to determine the age at spermarche of boys in urban area of ​​Manokwari West Papua Province. The method used in this research is cross sectional with interview technique. Data collection of age at spermarche is done using status quo method. The mean age at spermarche was analyzed using a generalized linear model (GLM) probit analysis. The average age at spermarche of boys in urban area of ​​Manokwari, West Papua Province was 12.83 years younger than the age at spermarche in rural areas of West Papua and western Indonesia. These characteristic reveals the response of plasticity in understanding the natural history of a population.
