Abstract

The purpose of this study was to observe the effect of Eucheuma cottonii consumption to the diabetic blood glucose level. Study on reducing blood glucose by consuming seaweed E. cottonii was conducted using male wistar rat (Ratus norvegicus). Rats were made to a hyperglycemic condition by aloxan injection before given ransom contains of 5, 10, 15, 20% (w/w) E. cottonii, standard ransom (negative control), and parental glibenklamid (positive control). The result showed that standard ransom was not able to reduce blood glucose from hyperglycemic to normal level, while ransoms with E. cottonii were able to do so. The higher E. cottonii seaweed level in the ransom had the higher capacity to decrease blood glucose level. The ransom with 20 and 15% E. cottonii were able to reduce blood glucose in 18 and 21 days, respectively.This treatment has the same ability as glibenklamid medicine which also reduced blood glucose to normal level in 18 days. Ransom with 5 and 10% E. cottonii were also able to reduce blood glucose level but the normal blood glucose level could not be achieved until 21st day.

Abstract

Kitosan adalah polimer alam penting yang mampu mengadsorbsi kandungan logam berat pada air limbah. Sebagai bahan adsorben logam berat, kitosan memiliki beberapa keterbatasan diantaranyasifat mekanik yang relatif rendah serta kelarutannya dipengaruhi oleh pH larutan. Untuk memperbaiki sifat tersebut maka dilakukan modifikasi kitosan dengan menggunakan natrium-tripolifosfat sebagaibahan cross-linking. Pada penelitian ini bertujuan mensinthesis serta mengkarakterisasi mikropartikel kitosan yang dimodifikasi dengan gugus tripolifosfat pada konsentrasi kitosan terlarut yaitu 0,5 mg/ldan 3 mg/l. Modifikasi kitosan dilakukan dengan menggunakan metode ionic gelation dengan natrium tripolifosfat. Hasil penelitian menunjukkan bahwa metode ionic gelation dapat memperkecil kitosanhingga berukuran mikrometer. Hasil SEM menunjukkan kitosan yang disintesis pada konsentrasi rendah memiliki tingkat aglomerasi yang lebih rendah. Analisis TGA pada kedua sample tersebut menunjukkanbahwa kitosan yang telah di cross-linking dengan gugus fosfat memiliki kestabilan termal yang cukup baik hingga temperature 800 oC. Analisa FT-IR pada kedua sample menunjukkan karakteristik yang hampir sama terutama pada panjang gelombang dimana peak terlihat secara signifikan.Kitosan adalah polimer alam penting yang mampu mengadsorbsi kandungan logam berat pada airlimbah.

Abstract

The aim of this research was to know the distribution pattern of mucus lectin from the different tissue of tilapia (Oreochromis mossambicus). The samples were taken from the epithelium of buccal cavity, gills, esophagus and skin of tilapia with standard body length (SL) 15.2-25.0 cm and body weight (BW) 145-250 g. Histochemical slides were observed under fluorescent microscope. The results showed that tilapia had four kinds of different lectin, such as wheat germ agglutinin (WGA), peanut aglutinin (PNA) and dolichos biflorus (DBA). Wheat germ agglutinin lectin was present in the epithelium of buccal cavity, gill, esophagus and skin. Staining intensity of WGA mucus lectin was strong in the epithelium of buccal cavity, gill, esophagus and skin. While the PNA was present in the epithelium of buccal cavity and esophagus, and DBA lectin was only present in the esophagus. The intensity of staining of PNA was weak, both in the epithelium of buccal cavity and esophagus, same with DBA lectin which was found in the esophagus.

Abstract

This research was aims to determine the form, level and the factors affecting women’s participation in mangrove conservation at Pasar Banggi Village, Rembang District. Survey was conducted on respondents with total number of 95 people, comprised of 50 women, 14 men, 10 children and 25 people representing related agencies were interviewed with semi-open questionnaire. The study showed that there were nine forms of female participation in conservation activities, which was women who are looking for information, planting seeds, fi ll polybags, nursery planning, decision-making in the implementation of the nursery, nurture the seeds of mangrove, mangrove preserve, transfer of knowledge to children and warn if there is people cut the tree. Based on Arnstein (1969) participation ladder, the study showed that female participation rates ranging from therapy to the partnership. Factors that affect women in conservation were women’s perceptions of themselves, social status and public perception of women’s participation. Women play an important role in the cycle of mangrove conservation, especially in the nursery stage. Nevertheless, women have not been involved in the decision-making process and enjoy the sale of mangrove seedlings. Strengthening women’s bargaining power and involvement in the management group is required to enable the equality of access and control between men and women in a cycle of mangrove conservation.

Abstract

Cross-breeding between Janti’s Black Tilapia (female parent) and Janti’s White Tilapia (male parent) has been performed by Institution of Germination and Freshwater Fish Farming which is located at Janti Village – District of Klaten and produced Tilapia Larasati (Red Tilapia Strain Janti) F5. This study aimed to compare the Tilapia Larasati F5 and it parents based on morphometric and meristic characters, and to know the length-weight relationship of three strains of tilapia. Analysis of morphometric characters performed by Principal Component Analysis (PCA) while the meristic character analyzed descriptively by reviewing the literature. Kinship of three strains were tested by cluster analysis while length-weight relationship analysis was conducted to determine the pattern of fi sh growth and condition factor . The scatter plot results of the 12 morphometric characters showed that Tilapia Larasati F5 has a similar body form with Janti’s Black Tilapia and has a slightly different form of Janti’s White Tilapia especially in the part of head. Tilapia Larasati F5 and Janti’s Black Tilapia obtained on a longer body, longer forehead, longer jaw (big mouth), and long face and long nose. It result supported by cluster analysis which showed that Tilapia Larasati F5 has a closer kinship distance to Janti’s Black Tilapia viewed from morphometric characters. Analysis of meristic characters showed that the number of scales on the dorsal fi n in front of the Tilapia Larasati F5 and Janti’s Black Tilapia amounted to more than the Janti’s White Tilapia. Third tilapia strains had isometric growth pattern. Analysis of the value of condition factor indicates that Tilapia Larasati F5 has the best body condition.
