Pertumbuhan dan Perkembangan Pheretima sp. Pada Media Komposisi Limbah Peternakan Ayam dan Serbuk Sengon INTISARI Isti Suhartini Bahri 12/329781/BI/8829 Pertumbuhan dan perkembangan cacing tanah dipengaruhi oleh media limbah organik yang sesuai. Limbah organik sebagai media bagi cacing tanah (Pheretima sp.) dapat meningkatkan pertumbuhan dan perkembangan cacing tanah. Limbah organik yang dipakai pada penelitian yaitu komposisi limbah peternakan ayam dan serbuk sengon. Penelitian ini bertujuan untuk mengamati pertumbuhan dan perkembangan pada media komposisi limbah peternakan ayam dan serbuk sengon, serta untuk mengetahui pertumbuhan dan perkembangan Pheretima sp. yang optimum pada komposisi media tersebut. Rancangan dari penelitian yaitu rancangan acak lengkap dengan 5 perlakuan dan 3 kali ulangan meliputi perlakuan I sebagai kontrol diberikan 100% serbuk sengon tanpa limbah peternakan ayam, perlakuan II diberikan 25% limbah peternakan ayam dengan 75% serbuk sengon, dan perlakuan III diberikan 50% limbah peternakan ayam dengan 50% serbuk sengon, perlakuan IV diberikan 75% limbah peternakan ayam dengan 25 % serbuk sengon, dan perlakuan V diberikan 100% limbah peternakan ayam tanpa serbuk sengon. Cacing Pheretima sp. dengan biomassa 100 gram dipelihara selama 60 hari. Perlakuan dilakukan dengan penimbangan biomassa cacing, penimbangan biomassa media, perhitungan jumlah kokon, dan perhitungan rasio C/N media yang diukur sebelum dan sesudah penelitian, serta pengukuran parameter lingkungan pada masing-masing perlakuan. Data yang diperoleh dianalisis menggunakan DMRT One Way ANOVA pada taraf uji 95%. Hasil dari penelitian yaitu biomassa pada cacing Pheretima sp. mengalami pertambahan biomassa tertinggi dari perlakuan 50% limbah peternakan ayam dengan 50% serbuk sengon 16,86 gram dan penurunan biomassa terendah pada perlakuan 100 % limbah peternakan ayam 3,39 gram. Jumlah kokon yang paling banyak terdapat pada perlakuan 25% limbah peternakan ayam dengan 75% serbuk sengon sebanyak 29 kokon. Penurunan biomassa media tertinggi pada perlakuan komposisi media 50% limbah peternakan ayam 50% serbuk sengon 1.597 gram. Penurunan biomassa terendah pada perlakuan komposisi media 100% limbah peternakan ayam 872 gram. Pada penelitian ini komposisi media 25% limbah peternakan ayam dengan 75% serbuk sengon optimum untuk pertumbuhan dan perkembangan cacing Pheretima sp.

The Growth and Development of Earthworm Pheretima sp. on The Composition of Chicken Farm Waste and Sengon Powders media ABSTRACT Isti Suhartini Bahri 12/329781/BI/8829 Growth and development of earthworms influenced by suitable media organic waste. Organic waste as a medium for earthworms (Pheretima sp.) can promotes the growth and development of earthworms. In this study researcher use Organic waste from the composition of chicken farm waste and sengon powders media. This study has aim to observe the growth and development of media composition organic waste in form of chicken farm waste and sengon powders media, as well as to determine optimal growth and development of Pheretima sp. onthose composition.The research design is completely random design with 5 treatments and 3 replications, includes treatment I as a controller is gives 100% sengon powder without chicken farm waste, treatment II is gives 25% of chicken farm waste with 75% sengon powder media, treatment III is gives 50% of chicken farm waste with 50 % sengon powder media, treatment IV is gives to 75% of chicken farm waste with 25% sengon powders media and treatment V gives 100% of chicken farm waste without sengon powders media. Meanwhile Pheretima sp. with biomass 100 grams is maintaines for 60 days. Researcher do treatment by weighing biomass worms, weighing biomass media, calculates the number of cocoon, and calculates of C / N ratio measured media before and after research, as well asmeasurements of environmental parameters on each treatment. The data were analyzed using the Duncan Multiple One Way ANOVA on test level of 95%.Result of this researchis the biomass of worms Pheretima sp. accreting highest biomass of treatment with chicken farm waste 50% and sengon powder media 50% is 16.86 grams. While the lowest biomass on treatment with chicken farm waste 100% is 3.39 g. The highest number of cocoon is 29 cocoons. It�s found by treatment of 25% chicken farm waste and 75% sengon powder media. The decline in highest biomass is 1,597 grams, with media composition 50% chicken farm waste and 50% sengon powder media. Decrease of the lowest biomass is 872 gram with media composition 100% chicken farm waste. We can concludes that suitable media to growth and develops of Pheretima sp. is 25% chicken farm waste and 75% sengon powder media.
