Performa Kuantitatif Sapi Peranakan Ongole Pasca Sapih di Sentra Peternakan Rakyat Maju Sejahtera Kabupaten Lampung Selatan

The research was conducted with the aim to know the quantitative performance of post-wean PO cattle in SPR Maju Sejahtera Tanjungsari District, South Lampung Regency. The observation was conducted on PO cattle in each group member. The sample of observation was determined by purposive sampling. The survey method used in this study was conducted from October to November 2017. The observed variables were quantitative performance (body length, height, chest circumference, and body weight) PO cattle in age group P1 (> 12 - 24 months) and P2 (> 24-36 months). The result of the observation was analyzed by descriptive method. The results showed that the average quantitative performance of PO Cows age group P1 (12-24 months) ie body length 115,00 ± 7.45 cm, height 119.70 ± 8.75 cm, chest circumference 141.19 ± 5.62 cm, and body weight 177,66 ± 21,39 kg. Average quantitative performance PO cows age group P2 (24 - 36 months) ie body length 139.73 ± 4.33 cm, height 128.32 ± 7.19 cm, chest circumference 154.21 ± 10.43 cm, and body weight 258,16 ± 29,91 kg

Microplastics contamination in commercial fish landed at Lengkong Fish Auction Point, Central Java, Indonesia

Plastic is one of the main pollutant sources that are difficult to decompose and then carried into the ocean and fragmented into smaller parts (microplastics) due to UV radiation and water currents. Their small size means that microplastics are often ingested by aquatic organisms, such as fish. This research aimed to determine the presence, abundance, and types of microplastics in the digestive tract of four dominant fishes landed at Lengkong Fish Auction Point, Cilacap, Central Java, i.e. threadfin (Eleutheronema tetradactylum), mackerel (Rastrelliger sp.), threadfin bream (Nemipterus japonicus), and hairtail (Trichiurus lepturus). We found microplastics in the digestive tract of four selected fishes with a frequency of occurrence of 100%. The concentration of microplastics in fish digestive tracts is relatively high, with a value range of 12 ±2.86 to 28.33 ±8.11 particles∙ind.-1. Microplastics were found in films, fibres, fragments, and granule shape types with various colours: brown, purple, blue, black, green, transparent, and yellow. The polymers found were polystyrene (PS), nylon, acrylonitrile butadiene styrene (ABS), polyurethane (PU), polypropylene (PP), high-density polyethylene (HDPE), and low-density polyethylene (LDPE). The present study provides baseline data for microplastics contamination in commercial fish species landed at Lengkong Fish Auction Point, Cilacap, Central Java, Indonesia. The fact that we discovered PU, the most harmful polymer, piques our attention
