Abstract

The aims of this study were to determine the diversity of phenotypes and the status of environmental carrying capacity in local chicken cultivation in Merawang District, Bangka Regency. This research was conducted in 5 villages in Merawang District which have many local chicken coops. The sampling method used is purposive sampling. Data analysis was carried out by gender. The parameters observed in this study were phenotype observations in the form of qualitative characteristics (feather color, feather pattern, feather pattern, feather flickering, shark color and comb type) and quantitative traits (chicken body weight, chicken, chicken breast circumference, length of femur, shank length and environmental parameters). The results obtained were 164 local chickens. The chickens obtained consisted of 108 female chickens and 56 male chickens. The results showed the dominant comb shape was rose (male) and pea (female), feather color was white (male) and colored (female), yellow shank color, feather pattern for both males. and dominantly striated females. The dominant feather pattern is Colombia, while the flickering feathers are dominant for both local and female chickens. The results showed that the body weight of local chickens in five villages, Merawang District had an average of 12.6 ± 9.33 kg (male) and 192.4 ± 2.87 kg (female). Based on body size data, values in millimeters (mm) were obtained for males and females, such as body length 1.734 ± 51.53 and 3.091 ± 104.13; shank lengths 306.6±9.78 and 551.8±18.16; thigh (femur) length 749±28.53 and 1,403±46.74; calf length (tibia) 702±17.60 and 1,228±38.29; and shank circumferences 63.6 ±1.16 and 121±3.77. The average temperature of the cage during observation was 28ºC with feed given an average of three times a day, namely in the morning, afternoon and evening. Environmental factors such as housing and temperature become the carrying capacity of local chicken cultivation in Bangka.

Abstract

This study aims to determine distribution patterns, calculate the diversity of pollinator insects, and analyze the relationship between environmental factors and the number of species and individual pollinator insects in Calamansi. This research is located in Jada Bahrin Village (station 1), Balunijuk Village (station 2), and Air Jangkang Village (station 3). The research location was determined based on the exploratory method of sampling insects using sweep nets and vane traps. Based on the research results, 811 individual insects were obtained, consisting of 300 pollinator insects (2 orders, 6 families, and 27 species) and 511 non-pollinator insects (4 orders, 14 families, and 18 species). The most common insect family was the Nymphalidae family with 101 individuals, and the least common was the Lycaneidae family with 2 individuals. The diversity index (3.360), wealth index (6.723), and evenness index (0.802) are included in the high category, while the dominance index is low (0.042). The distribution pattern of pollinator insects at the three stations is included in the uniform category. The results of the PCA analysis showed that the diversity, distribution pattern, and number of individuals were affected by air temperature, while the number of species was affected by air humidity and light intensity.
