Judul: Bioecology of Earthworm Pheretima darnleiensis
Abstrak: Pheretima darnleiensis is a native earthworm in Southeast Asia, India, Japan, and Indonesia, however there is lack of study on P. darnleiensis. Determining the characteristics of P. darnleiensis and the ecology surrounding its habitat is needed in order to culture the earthworm. Hence, this study was aimed to study the structure of several organs and morphological characters that can be used to identify P. darnleiensis and its habitat condition. Earthworms were collected in a plot of 100 x 100 x 20 cm in 10 locations and were identified. The structure of P. darnleiensis organs was studied histologically using paraffin. Pheretima darnleiensis did not have diverticula and stalked gland on copulatory pouches, nephridia occurred on bithecate spermatheca, and the first spermathecal pores were at segment 4/5. Based on this study, the highest population of P. darnleiensis was found in an area containing abundance of other earthworm species at 15 individuals/m2, plant cover at 25.00%, soil arthropods at 16.32 individuals/kg fresh soil, abiotic component cover at 78.50%, soil temperature at 27.42 ± 1.01 oC, soil pH at 5.77 ± 0.53, soil moisture at 19.83 ± 9.92%, organic carbon at 3.39%, N at 0.29%, P at 286.80 ppm, K at 500.00 ppm, sand at 28.76%, silt at 38.74%, and clay at 32.50%. Silt fraction could be considered as one of factors influencing P. darnleiensis abundance.

Abstrak: A research on earthworm diversity was conducted on three types of habitats, the abandoned land, rice fields and horticultural plantations at different heights of Bogor and Bekasi. This study aims to determine earthworm diversity in different habitat and heights. A quadrat measuring 30x30 cm2 was used in 5x5 m2 plot in collecting the earthworm. Ten species of earthworms were obtained in the Bogor region, namely Metaphire houlleti, Pontoscolex corethrurus, Perionyx excavatus, Perionyx sp 1, Eudrilus eugeniae, Dichogaster sp., Glyphidrilus sp., and three unidentified species. Earthworms obtained in Bekasi were also of 10 species, namely Amynthas Agrestis, Metaphire houlleti, Pontoscolex corethrurus, Perionyx excavatus, Perionyx sp 2, Polypheretima elongata, Glyphidrilus sp., and three unidentified species. The highest diversity was in the horticultural plantations (H '= 0.65) for Bogor area. The horticultural plantation in Bogor region also has the highest uniformity index value (E = 0.80), and has the lowest value of Simpson's dominance index (C = 0.56).

Abstrak: Adanya revolusi informasi dan globalisasi menjadikan persaingan semakin tajam, karena tidak lagi terbatas pada persaingan antara sesama perusahaan domestik tetapi juga dengan perusahaan multinasional. Ini terjadi pada hampir semua bidang usaha. Entry bariers hampir-hampir tidak ada lagi pada dunia industri. Kalau pendatang baru domestik tidak ada, maka pendatang dari luar negeri pun akan tetap muncul, sehingga menyebabkan persaingan semakin tinggi. Bargaining power pelanggan meningkat sedemikian rupa sehingga industri atau dunia usaha terus mengikutinya dan dapat menciptakan organisasi yang dapat memberi pelayanan yang memuaskan kepada pelanggan. Dengan kata lain setiap perusahaan dituntut untuk mengembangkan strategi yang antisipatif terhadap kecenderungan- kecenderungan baru guna mencapai dan mempertahankan posisi bisnisnya. Penggunaan berbagai teknologi dilakukan pelaku bisnis untuk mengadopsi proses pembuatan strategi yang lebih terarah dan canggih seperti yang dilakukan oleh para ahli strategi perang. Proses strategi kemudian digabungkan dengan fungsi-fungsi manajemen yaitu perencanaan, penerapan dan pengawasan dan disebut manajemen stategi. IPB Univers PT. Melati Jakarta Indonesia merupakan salah satu perusahaan yang bergerak di bisnis minuman instan. Kegiatan pengolahan tanaman obat menjadi minuman instan merupakan salah satu industri yang menghadapi perubahan lingkungan. Lingkungan tersebut meliputi lingkungan eksternal dan lingkungan internal. ..dst
