Abstract

Northern coastal areas of Central Java potentially produces sharks and rays (Chondrichthyes) for dishes. However, lack of community understanding of protected species catchment affects the Chondrichthyans conservation management. This study aimed to identify of total Chondrichthyans that were captured by fisherman correlated to the conservation knowledge and action in northern coastal areas of Central Java. This research was conducted by using interview, and direct observation. Samples were collected in fish capture household places in Tegal, Pemalang, Pekalongan, Semarang, Pati, and identified in Animal Taxonomy Laboratory of Biology Department, Universitas Negeri Semarang. Data were analyzed using descriptive qualitative based on the morphology characteristic. This research found that every season, at least 1,106 individuals from 23 species of Rajiformis and Lamniformis (Chondrichthyes) orders was captured. This condition was aggravated with lack of access to information and low fisherman’ awareness of protected species. It was also found that shark and ray trading generates value chain in culinary business. It increases fish consumption demand that only can be provided by fish catchment from the ocean. The implication of species catchment is declining population of Chondrichthyes in Central Java north areas. Based on the research, a high demand and lack of access to information correlated with declining community awareness on conservation actions. this research adds more information as an effort to conserve shark and ray species based on problems faced by fishermen. The information is also able to be applied as a foundation to develop community based conservation action.

Abstract

The Extract of Aloe Vera Peel (EAVP) contains bioactive compounds (flavonoids, alkaloids, tannins, saponins, and phenolics) that it thought to improve pancreas histopatology on rat with diabetes mellitus, therefore it has potential for diabetes mellitus treatment. This research aimed to figure out the effect of EAVP on improving the histopathology of rat pancreas induced by alloxan. This research was an experimental study using a completely randomized design with a randomized post-test design. A total of 25 rats were divided into 5 groups: C(-) was a normal group, fed and drinking standard; C(+) was positive control group, induced by alloxan 120 mg/kgBW; PI, PII and PIII were groups that were induced by alloxan 120 mg/kgBW and were given a full-dose of EAVP of 87.5, 175 and 350 mg/kgBW respectively. The data was assessed using the Kruskal-Wallis and Mann-Whitney statistical analysis. The results of the statistical test showed that the histopathology of rat pancreas of the C(+) group were significantly different compared with the treatment group. Meanwhile, the representation of histopathology of pancreas between PIII and C(-) were not significantly different. It can be concluded that treating hyperglycemia rats with the EAVP for 28 days can improve the representation of histopathology of rat pancreas. At the laboratory level, EAVP has been shown to repair rat pancreatic damage. With this result, Aloe vera has the potential to be developed as a phytopharmaca for the prevention or treatment of diabetes mellitus.
