Judul: Model of Industrial Tea Raw Material Planning (Case Study in PTPN VIII Kebun Cianten, West Java)
Abstrak: Perencanaan merupakan hal yang sangat penting pada industri teh. Sebuah rencana akan sangat mempengaruhi sukses dan tidaknya suatu pekerjaan. Teh (Camellia sinensis) merupakan tanaman yang telah dibudidayakan sejak lama dan sering dimanfaatkan sebagai minuman. Salah satu perusahaan negara yang menghasilkan komoditas teh adalah PT Perkebunan Nusantara VIII Kebun Cianten. Pada kebun tersebut terdapat pabrik pengolahan teh hitam CTC (crushing, tearing, and curling). Permasalahan yang ada pada pabrik tersebut adalah perencanaan pemetikan teh yang optimal, penjadwalan kebutuhan tanaga pemetik, serta perencannan bahan penunjang produksi (kayu bakar dan papersack).

Judul: Telaahan Pengelolaan kebun dalam menyediakan pucuk sebagai bahan baku pengolahan teh hitam  : (Studi kasus di Perkebunan Gunung MAs, PT Perkebunan XII Kecamatan Cisarua, Kabupaten Bogor, Jawa Barat)
Abstrak: Industri teh masih mempunyai prospek yang cukup cerah jika dilihat dari adanya peluang konsumsi untuk pasaran internasional dan donenstik. Pengembangan industri teh memerlukan jaminan kepastian bahan baku pucuk teh sebagai komponen utama dari proses pengolahan. Jaminan kepastian akan adanya pucuk mencakup kuantitas dan kualitas dengan biaya yang optimal. PT Perkebunan yang mengusahakan teh umumnya menghada- pi permasalahan tidak tercapainya kapasitas terpasang pada pabrik pengolahan. Artinya PT Perkebunan tidak bekerja secara kapasitas penuh (full capacity). Pengelolaan kebun yang baik dapat menyediakanpucuk teh dengan kuntitas, kualitas dan biaya yang optimal sehingga unit-unit kebun yang ada dapat bekerja secara efisien. Produksi pucuk teh Perkebunan Gunung Mas selama empat tahun terakhir menunjukkan kenaikan sebesar 6,15 persen per tahun. Kenaikan ini disebabkanoleh peningkatan pro- duktivitas kebun-kebun yang ada di Perkebunan Gunung Mas. ...

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
