Judul: Karakteristik Alat Tangkap Purse Seine Waring di Pelabuhan Perikanan Pantai Dadap Kabupaten Indramayu, Jawa Barat.
Abstrak: Purse seine waring in Dadap is constructed by using mesh size 1,0 mm with the main catch of purse seine waring is anchovy (Stolephorus spp). During the day the total catch of purse seine waring is 223,8 kg, which is comprises of the main target anchovy 59,2 kg (25%), selaroides 34,5 kg (15%), mackerel fish 9,5 kg (4%), pony fish 3 kg (1%), pomfret fish 8,5 kg (4%), and others 36,1 kg (16%). During the night the total catch of purse seine waring is 528,8 kg, which is comprises of the main target anchovy 227 kg (43%), sardine 188 kg (36%), squid 28,1 kg (5%), scad 27,5 kg (5%), pony fish 12 kg (2%), and others 41,7 kg (8%). Total length of average the main target anchovy 6,75 ± 0.05 cm, selaroides 4,5 ± 0,24 cm, mackerel fish 26,5 ± 1,13 cm, pony fish 3,5 ± 0,19 cm, and sardine 7,5 ± 0,20 cm. The analysis single factor is Fhit > Ftab (α 0,05) is 10,93, there are significant differences of the result of purse seine waring in the day and at night.

Judul: Kajian Unit Penangkapan Purse Seine dan Kemungkinan Pengembangannya di Indramayu
Abstrak: Alat tangkap yang digunakan oleh nelayan di Kabupaten Indramayu adalah purse seine, gill net, lampara, jaring Mitik, pancing, sero, pukat pantai dan dogol. Diantara alat tangkap tersebut purse seine mempakan alat tangkap yang produktif dibandingkan alat tangkap lainnya yang terdapat di Kabupaten Indramayu dengan rata-rata perkembangan produksi sebesar 21,34% per tahun (DKP Indramayu, 2001). Ukuran unit penangkapan ini berukuran lebih besar dibandingkan unit penangkapan lainnya yang ada di Indramayu dan menyerap tenaga kerja yang besar pula sehingga diharapkan dapat mengurangi tingkat pengangguran di daerah tersebut. Berdasarkan keadaan tersebut, maka penulis tertarik untuk melakukan penelitian tentang kajian unit penangkapan purse seine dan kemungkinan pengembangannya di Kabupaten Indramayu.

Judul: Biokonversi Xilosa menjadi Xilitol Melalui Optimasi Aerasi dan Penambahan Kosusbtrat oleh Candida tropicalis
Abstrak: Bioconversion of xylose into xylitol using Candida tripocalis become an alternative method to yield xylitol in low cost and efficient so it can fulfilled the xylitol availability in xylitol trading which is relatively low. This study did xylitol production through aeration optimization and addition of co-substrate Aeration conditions that used in this research are 25 mL, 32.5 mL, 50 mL, 67.5 mL, and 75 mL in 125 mL Erlenmeyer flask. Glucose concentrations added are 15 g/L, 30 g/L, 45 g/L, and 60 g/L in 75 mL fermentation media. Measurement of xylitol concentration determined by spectrophotometer method using D-sorbitol/Dxylitol kit wavelength 495 nm. The result of research performed on optimum aeration conditions for bioconversion xylose into xylitol is 75 mL fermentation medium in 125 mL Erlenmeyer flask with xylitol concentration of 6.3790 g/L. Xylitol consentration after the addition of glucose 45 g/L with xylitol consentration of 1.6837 g/L. Addition of glucose lowered xylitol production of 76.82%, so that the fermentation glucose in the medium is not recommended in xylitol production. Glucose can not increase the concentration xylitol, but a role in increasing the cell biomass.
