Judul: Performa Cacing Tanah (Lumbricus rubellus) pada Media Kotoran Sapi dengan Penambahan Tepung Kulit Kakao
Abstrak: Cacing tanah merupakan salah satu organisme pengurai, penguraian oleh cacing tanah dapat 3-5 kali lebih cepat dibandingkan mikroba. Media cacing tanah dari kotoran sapi dapat ditambahkan pada limbah lain yang telah difermentasi atau diurai. Limbah kotoran sapi dan kulit kakao dapat digunakan sebagai media tumbuh cacing tanah. Penelitian ini bertujuan menganalisis performa cacing (Lumbricus rubellus) terhadap kotoran sapi dengan penambahan kulit kakao sebagai media hidup dengan taraf yang berbeda. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 (empat) perlakuan dan 1 (satu) kontrol yang masing-masing diulang sebanyak 3 (tiga) kali dan dianalisis dengan uji lanjut Tukey. Media pemeliharaan dengan penambahan tepung kulit kakao berpengaruh (P<0,05) meningkatkan performa cacing tanah (Lumbricus rubellus). Penambahan tepung kulit kakao pada media kotoran sapi sampai 15% lebih baik dari perlakuan yang lainnya karena dapat meningkatkan performa cacing tanah (Lumbricus rubellus) diantaranya yaitu bobot total cacing 111,67 gram, produksi kokon 134,00 butir dan media yang berkurang rata-rata 569,33 gram, Earthworms are one of the decomposer organisms, decomposition by hworms can be 3-5 times faster than microbes. Earthworm media from cow ng can be added to other wastes that have been fermented or decomposed. Cow ng and cocoa shell waste can be used as a medium for growing earthworms. s study aims to analyze the performance of worms (Lumbricus rubellus) on le manure with the addition of cocoa shell as a living medium with different els. The design used in this study was a completely randomized design (CRD) h 4 (four) treatments and 1 (one) control, each of which was repeated 3 (three) es and analyzed by Tukey's follow-up test. The rearing medium with the ition of cocoa shell flour had an effect (P<0.05) on improving the performance earthworms (Lumbricus rubellus). The addition of cocoa shell powder to cow ng media is up to 15% better than other treatments because it can improve the formance of earthworms (Lumbricus rubellus) including the total worm weight 111.67 grams, cocoon production of 134.00 grains and an average reduced dia of 569.33 grams.

Judul: Productivity of Earthworms (Lumbricus rubellus) in Mixed Media of Cow Manure and Chicken Manure with Different Levels
Abstrak: Cacing tanah atau jenis Lumbricus rubellus tergolong dalam kelompok avertebrata atau tidak bertulang belakang yang memiliki potensi dan banyak manfaat serta mudah dibudidayaka dengan menggunakan media kotoran ternak. Tujuan penelitian ini menganalisis produktivitas cacing tanah (Lumbricus rubellus) dalam media campuran kotoran sapi dan kotoran ayam dengan taraf yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan dengan uji lanjut Duncan. Media yang digunakan kotoran sapi dengan penambahan kotoran ayam IPB-D1 dengan taraf berbeda. Hasil penelitian menunjukkan penggunaan kotoran sapi dengan penambahan kotoran ayam IPB-D1 berpengaruh nyata (P<0,05) terhadap produktivitas cacing tanah. Penggunaan kotoran sapi sebanyak 95% dengan penambahan kotoran ayam sebanyak 5% berpengaruh nyata dan dapat meningkatkan jumlah populasi cacing tanah (Lumbricus rubellus) sebanyak 285,67 g dan penyusutan media sebesar 164,17 g. Penggunaan kotoran sapi sebanyak 85% dengan penambahan kotoran ayam sebanyak 15% dapat meningkatkan bobot cacing tanah sebesar 17,09 g dan produksi kokon sebanyak 155,58 butir. Pencampuran kotoran ayam pada kotoran sapi sebanyak ≤15% baik untuk produktivitas cacing Lumbricus rubellus, sebaliknya >15% menurunkan produktivitas cacing tanah., Earthworms or type Lumbricus rubellus belong to the group of invertebrates or not vertebrates that have the potential and many benefits and are easily cultivated using livestock manure media. The purpose of this study was to analyze the productivity of earthworms (Lumbricus rubellus) in mixed media of cow manure and chicken manure with different levels. This study used a complete randomized design (RAL) with 6 treatments and 3 replications with Duncan's further test. Media used cow manure with the addition of chicken manure IPB-D1 with different levels. The results showed the use of cow dung with chicken manure addition IPB-D1 significant effect (P<0.05) on productivity of earthworms. The use of cow manure as much as 95% with the addition of chicken manure as much as 5% effect and could increase population of earthworms (Lumbricus rubellus) as much as 285.67 g and shrinkage of the media by 164.17 g. The use of 85% cow manure with the addition of 15% chicken manure could increase the weight of earthworms by 17.09 g and cocoon production by 155.58 grains. The use of cow manure with the addition of chicken manure exceeds 15% could actually reduce the productivity of earthworms Lumbricus rubellus.

Judul: Asymptotic Distribution of Estimator for the Intensity Function of a Doubly Periodic Poisson Process
Abstrak: In this manuscript, estimation of the intensity function of a doubly periodic Poisson process is discussed. It is assumed that only a single realization of the Poisson process is observed in a bounded window [0,n]. It is also assumed that the period of the intensity function is known. The rate of consistency and asymptotic normality of the estimator are formulated. Finally, a confidence interval for the local intensity function is also formulated.
