Judul: Karakteristik Payang Gemplo (Seine Net) di Pelabuhan Perikanan Pantai Dadap, Kabupaten Indramayu.
Abstrak: Payang gemplo consists of three parts, such as wings, body and bag. Mesh size in the bag is 0,1cm and 0,4 cm, body is 10,5-35 cm and wing is 40 cm. The main catch is an anchovy (Stolephorus sp.) and small pelagic fish. Catching method of payang uses one boat system and fishing operations carried out during the day (one day fishing) with a boat size of 3 to 5 GT. The composition of the catch comprises of anchovy (Stolephorus sp.) as a target catch with 43,73%. While the bycatch consists of other fish 22,74%, such as pony fish (Leiognathus dussumieri) 11,37%, long jawed mackerel (Rastrelliger sp.) 10,2%, sardine (Sardinella gibbosa) 4,90%, hair tail (Trichiurus savala) 2,90%, and pomfret fish (Pampus argentus) and mackerel (Selaroides sp.) each for 2,07%. Based on the analysis of the Shannon-Wiener diversity index indicated value of the index at 1,24 or > 0,1 which means payang gemplo fishing gear in Dadap is categorized low selectivity.

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.
