Karakteristik Sensori, Kimia dan Fisik Pempek dari Ikan Tenggiri dan Ikan Kiter pada Berbagai Formulasi

Pempek is one of the traditional snack food from Palembang which is made from fish and very popular in Indonesia. The objective of this study was to determine the effect of the combination of barred mackerel fish and pick handle barracuda fish meat on sensory, chemical, and physical properties and to determine the best economic formulation of pempek. This study used the Completely Randomized Design with six-level treatments of a combination of barred mackerel fish and pick handle barracuda fish, respectively, 200 g-0 g (P1), 160 g-40 g (P2), 120 g-80 g (P3), 80 g-120 g (P4), 40 g-160 g (P5), and 0 g-200 g (P6). The characteristics of pempek were observed on the sensory (color, aroma, taste, texture, and overall acceptance), chemical (moisture and protein content), and physical properties (hardness, cohesiveness, springiness). The result showed that the treatment only has a significant effect on the color parameter of sensory properties. The higher amount of use of pick handle barracuda fish significantly reduced the panelist preference on color. The best formulation chosen was the combination of 40 g barred mackerel fish and 160 g pick handle barracuda with an economic total raw material cost of Rp 12.750. This formulation is recommended to produce pempek with the best quality and economic cost.Pempek is one of traditional snack food from Palembang which made from fish and very popular in Indonesia.

KAJIAN EFEKTIFITAS PENGGUNAAN TANAMAN ECENG GONDOK (Eichornia crassipes) DALAM MENURUNKAN BEBAN PENCEMAR AIR LIMBAH INDUSTRI GULA TEBU

Sugarcane industries produce wastewater with high levels of pollution load. Wastewater pollutant load can be lowered by treating wastewater in the WWTP. Wastewater treatment process using Biological conventional system still has the disadvantage of increasing the pH of the waste water at a given time. It causes algae blooming. Algae population levels increases due to nutrients in wastewater. To prevent algae  from blooming, nutrient concentration in the waste water should be reduced. This study was aimed to measure the effectiveness of Waterhyacinth in lowering pollutant load of sugar cane industrial wastewater. The method used was to plant Waterhyacinth in aeration pond number 2 of WWTP and then taking samples at four locations and consists of point I (inlet pond aeration 2), point A (before the water hyacinth plant), point B (after the water hyacinth plant), the point C (waste pond outlet monitor). Parameters measured included pH, TSS, COD, NH4, and NO3. The result showed the wastewater treatment system using water hyacinth plant reduced the pollutant load sugar cane industrial wastewater at the rate of  0,000858%/m2 day, 0,010997%/m2 day, 0,008691%/m2 day, 0,005936%/m2 day, and 0,015016%/m2 day, respectively. These conditions indicate planting hyacinth was effective in lowering the level of industrial wastewater pollutant load of sugar cane.
