Abstract

In the present work, a comprehensive statistical analysis was performed to evaluate the potential application of peel of local fruits from Malang, i.e. mangosteen, honey pineapple and red dragon fruits for natural yellow coloring agents. The yellow pigments from those fruit peels were extracted through a simple maceration method using distilled water, acetone and ethanol as the solvents. The CIE color space of the extracts was measured to obtain L*, a* and b* values. The obtained data were further analyzed using Principal Component Analysis (PCA), Multivariate Analysis of Variance (MANOVA) and Duncan Test to determine the most potent natural yellow coloring agent. All the extracts were appeared as mild to strong yellow liquid except for acetone extract for the peel of red dragon fruit extracts. From the CIE color space and PCA analysis, either ethanolic or acetone extracts of mangosteen appears as a strong yellow liquid and they are statistically not different. Interestingly, the MANOVA and Duncan test results are able to distinguish that the ethanolic extract of mangosteens’ peel as the best candidate for natural yellow coloring agents because of its lowest L* and also highest b* variable values.

Abstract

Community Based Management (CBM) makes people as the one who has a main role in the natural resource management. This management involves local people in planning, executing and also enjoying the result of that natural resource management. The basic principle of SBM is the government empowers the potency of local wisdom available in an area and make it as the principle of the coastal resource management. CBM can be seen in Awig-Awig Tradition in East Lombok and Sasi Tradition in Middle Maluku. Awig-Awig is a convention of East Lombok people. This convention becomes a written traditional law legalized by Village Regulation containing rules to regulate coastal resource management along with the sanction if it is broken. Awig-Awig is highly obeyed by East Lombok people that makes it suitable for empowering local people to manage their natural resources. Meanwhile, Sasi tradition on in Middle Maluku can be simply described as prohibition and license of catching fish in a certain period. As Awig-Awig in East Lombok, Sasi is also legalized by the traditional law and has sanction for those who break the law. These two traditions, Awig-Awig Tradition in East Lombok and Sasi Tradition di Middle Maluku, are both aimed at preserving the natural resources so that it can be the basic principle in Coastal Resources Community Based Management.

Abstract

The objectives of this research were to determine the genetic gain value of Tilapia Pandu F5 fry and to compare the growth between the fry of best 10 % (Top 10) of  Tilapia Pandu F5and the average Tilapia Pandu F5 (without selection). This study was done at Satker PBIAT (Centre of Fresh Water Fish Culture Working Unit) Janti Klaten. The  fries was kept in a happa (net cage) at the size of 4x2x1 m3 from nursery I-III. The stocking density was 500 fries/cage. The results of this investigation shows that the weight genetic gain of Tilapian Pandu F5 at nursery I-III was at the range of 60,12 % - 88,58 %. It was also shown that the best 10 %  selection (Top 10) Tilapia Pandu F5 fries growth better than the average Tilapia Pandu F5 fries without selection.

Abstract

Pigments from marine bacteria have attracted the attention for scientists because of their extensive applications and currently exploration of new pigment sources from marine bacteria is still ongoing. Recently, we have successfully isolated six new yellow-pigmented marine bacteria, strain PS2, PM2, SB11, SB13, SB21, and SB23, isolated from seawater from different sampling sites on Alor Island, Indonesia. The UV−Vis and FTIR spectra of the crude pigment extracts of the six strains showed the characteristics of tambjamines, a group of yellow pigments commonly found in nudibranchs and bryozoans. Moreover, separation and characterization of crude tambjamines extract resulted in five different types of tambjamine with maximum absorbance at the wavelength of 374−392 nm. Based on the analysis of 16S rRNA gene sequences, strain PM2 was closely related to several species in genus Pseudoalteromonas with a similarity of more than 99%. Strain PM2 was designed as Pseudoalteromonas sp. PM2 with accession number LC505058. So far, only two marine bacteria have been known to produce tambjamine and they are from genus Pseudoalteromonas. Our new finding indicated that in the group of marine bacteria, tambjamine might be only synthesized by members from genus Pseudoalteromonas.

Abstract

In the present work, we investigated the extract of honey pineapple peels in distilled water, ethanol, and acetone solvents. The spectroscopy study of each extract was performed using a Fourier transform infrared (FTIR) spectrometer, an ultraviolet-visible (UV-Vis) spectrophotometer, and a spectrofluorometer. The FTIR spectrum of the distilled water extract indicated that the distilled water extract may contain alcohol or carboxylic acid compounds. Meanwhile, the ethanolic extract may contain alcohol or carboxylic acid, or ether compounds. On the other hand, the acetone extract may contain alcohol or ether or aromatic or aliphatic compounds. The UV-Vis spectrum of the honey pineapple peels extracted in the distilled water, ethanol, and acetone showed a broad absorption signal at UV region (< 300 nm), four absorption signals at UV region (232-368 nm), and four absorption signals at UV region (231-368 nm) with a weak absorption signal at the visible region at 559 nm, respectively. The distilled water and acetone extracts gave fluorescence signals, however, the ethanolic extract showed no fluorescence intensity. From the FTIR, UV-Vis, and fluorescence spectra characterization, the extracted natural pigments from the honey pineapple peels in distilled water, ethanol, and acetone solvents were identified. The distilled water extract may contain polar flavonoid or steroid compounds while the ethanolic extract may contain polar carotenoid pigments. On the other hand, the acetone extract may contain carotenoid and chlorophyll pigments as shown by an emission signal at 670 nm.
