Judul: Kajian Penetapan Interval Titik dalam Metode Pemantauan Terumbu Karang Point Intercept Transect (PIT).
Abstrak: Point intercept transect method (PIT) is used to measure coral cover and benthic substrates quickly and efficiently. This study aimed to evaluate the establishment of an observation point at the interval point intercept transects method (PIT). Method of processing data in the form of calculation accuracy of data and one-way analysis of variance accuracy of PIT data contained test to see real differences in the methods compared. Highest in 0.1 meter interval point. This is caused by the density of data collection points closer to taking continuous data on methods LIT Interval point 0.9 meter and 1 meter showed the lowest accuracy since vacancy data width on the transect line. The whole value of each condition, components and lifeform on LIT methods and methods PIT point interval of 0.1 m to 1 meter does not have any real difference.

Judul: Keterkaitan Sedimentasi terhadap Kondisi Ekosistem Terumbu Karang di Perairan Teluk Lampung Provinsi Lampung
Abstrak: Sedimentation is one of the limiting factor for coral distribution through both the suspended and deposited sediment causing the reduce of light penetration and smothering the polip of coral reefs that can lead to coral death. The purpose of this study was to analyze the relationship of sedimentation with conditions of coral reef ecosystem through observing of the sedimentation rate and analyze community of coral reef. The transects were deployed at the three line series perpendicular wuth an interval of 50 m between the line. Each transect was pleaced at every 10 m along the line. Date within the transect were observed using the underwater camera. The images were analyzed by using CPCe software (Coral Point Count with Excel extensions). Sedimentation rate was measured by a sediment trap using PVC pipe with a diameter of 5 cm and 11.5 cm in height and partition (baffles) cover at the top. Sediment traps were mounted on a 12 mm diameter steel poles at a height of 20 cm from the bottom. Sediment traps were deployed for 20 days, then the recovered sediment was dried in an oven at 60 0C for 24 hours. Sedimentation rate varied between the stations with a range of values from 3.09 to 44.29 mg/cm2/day. The lowest rate of sedimentation was found in Station 7, while the highest was found at Station 1. Sedimentation rates are generally grouped into light untill moderate condition, whereas in some Stations (1, 3, and 6) showed heavy sedimentation rates. The high rate of sedimentation at Station 3 was probably due to close to the mouth of the river. Coral cover ranged from 8.75 to 60.85%, generally showing moderate categories. Severe damages were found in Station 1, 3, and 6 with a dominant form of massive coral, while good categories were found at Station 9 which located in a relatively remote area of influence of the river and dominated by foliose and brancing form. There was a strong indication of relationship sedimentation and coral reefs cover this research area.

Abstrak: Sorghum can be used as a basic ingredient in developing ready to eat cereals. The general aim of this study was to develop cereal milks based beverages with sorghum as a main ingredient. The materials used to make cereal milk sorghum were milk powder, sorghum flour, sugar, cocoa powder, vanillin powder, and salt. This study covered two stages of experiment, i.e. preliminary and main experiments. The objective of preliminary study was to produce sorghum flour that can be rehydrated and has good characteristics. Flour that can be rehydrated known as pragelatinized flour. Pragelatinized sorghum flour can be achieved by studying the comparison of the amount of water added in the cooking stage that studied in the preliminary experiment. The ratio of coarse sorghum flour and water (w/v) tested were 1 : 2.5, 1 : 3, 1 : 3.5, 1 : 4, 1 : 4.5. The physical properties of the products resulted such as yield, water solubility index, and the rehydration time were analyzed. Based on these test results, the ratio of flour and water to be used in the main study was 1 : 4. The main study aimed to get a cereal milk formula that was suitable and acceptable by consumers. Variables observed on the main research in determining the optimum formulation of cereal milk were the amount of pragelatinized sorghum flour and milk powder added. The organoleptic test conducted showed that the formulation with a ratio of milk and pragelatinized sorghum flour 3 : 7 was chosen. Based on proximate analysis, the chosen formula contain (dry basis) 5.82% moisture content, 5.87% fat, 8.16% protein, 2.73% ash, and 83.24% carbohydrate. Chosen formula also contain 14.76% dietary fibre and total phenolic compound 3.28 mg GAE (Gallic Acid Equivalent)/ g product. Financial analysis that has been done shows milk cereal product development is feasible.
