Abstract

One of the important factors in fish farming is feeding. Feed intake is able to affect the growth and production of fish, especially on nutritional content such as protein. In this research, Patin (Pangasius djambal), a catfish, were given variations in feed, i.e pellets only (P1) as a control; pellets and probiotic (P2); pellets and Azolla pinnata (P3). A. piñata (known locally as matalele) is a water plant that has complete essential amino acids including threonine, valine, methionine, isoleucine, leucine, phenylalanine, lysine, histidine, arginine and tryptophan. Probiotic is living microbial cells that affects the speed of feed fermentation and helps the absorption of food in the gastro intestinal tract. The results show that P2 gains more weight than P1 and P3. This feed variations also give different levels of crude protein in fish meat P1, P2, and P3 that are in the order 14.62%; 15.74%; and 13:35%. Based on the results of LC-MS analysis, the amount and the dominant amino acids content in the protein of P1, P2, and P3 are 13 amino acids–aspartic acid; 13 aminoacids–glutamic acid; and 14 amino acids and is predominantly asparagine. Keywords: protein, amino acid, patin, probiotic, Azolla pinnata

Abstract

Dye sensitized solar cells (DSSC) has been a popular research topic which benefits in high energy conversion efficiency and less cost in fabrication process. The components of DSSC consist of photoanode, electrolyte, and counter electrode that are arranged as sandwich. The photoanode contains ITO (indium tin oxide) glass covered by TiO2 particles, while the counter electrode contains ITO glass covered by composite of TiO2-graphite as counter electrode and red cabbage extract, as a dye agent. The cell was fabricated in various amount of graphite, i.e 10%; 30%; and 50 %, and time of soaking i.e 2; 13; 24; and 48 hours. The performance of the solar cell per active area of ​​1 cm2 was tested on irradiation of 75 Watt halogen lamp (distance 15 cm) and measured by multimeter and rheostat. The optimum synthesis condition of DSSC was obtained with composition of TiO2:graphite on the counter electrode is 70%:30 %, and soaking time in dye agent is for 24 hours. This cell results in an optimum performance, Isc = 0.028 mA ;Voc = 0.344 mV, FF = 0.29 and = 0.0055 % efficiency. Keywords: DSSC, Red Cabbage, Counter Electrode
