Phytoplankton Diversity as Ecological Indicator in Jimbaran Bay Waters

A study was carried out to evaluate the ecological condition in Jimbaran Bay Waters by using Phytoplankton Diversity Index. The study was conducted at Balangan, Pemuda, Jimbaran, Kedonganan, Kelan and Segara Beach located in Jimbaran Bay. Shannon-Wiener diversity index was used to analyze the ecological condition, supported by analysis on water quality including dissolved oxygen (DO), biological oxygen demand 5 days (BOD5), water pH, and water salinity. There were 51 species of phytoplankton classified to 5 classes had been observed from this study: Bacillariophycae, Cyanophyceae, Zygnemophyceae, Dinophyceae, and Chlorophyceae. Balangan beach showed higher diversity index (H) and evenness index (E) (H = 1.19; E = 0.29) compared to the other site (Pemuda: H = 0.89, E = 0.25; Jimbaran: H = 0.89, E = 0.26; Kedonganan: H = 0.96, E = 0.28; Kelan: H = 0.85, E = 0.20; and Segara: H = 0.91, E = 0.33). However, overall ecological condition showed diversity index more than 1 (H = 1.44; E = 0.27). Measurement of water quality showed that the highest quality of water was shown by Balangan Beach (DO 5.2 mg/L, pH 7.2, salinity 29 ppt, and BOD5 0.9 mg/L), while the lowest was shown by Kelan Beach (DO 4.2 mg/L, pH 7.2, salinity 29 ppt, and BOD5 2.9 mg/L). Result of the study showed that ecological status of Jimbaran Bay Waters was having moderate diversity, sufficient productivity, and medium ecological pressure (pollution)

Study on Mollusk and Algae or Phytoplankton Community in Southeast Waters of Bali

A study was carried out to observe the relation between mollusk with algae or phytoplankton in southeast waters of Bali. The study was conducted at Mertasari, Sindhu, Serangan, Purnama, and Kethewel beach. Shannon-Wiener diversity index was used to analyze the ecological condition, supported by analysis on water quality including dissolved oxygen (DO), biological oxygen demand 5 days (BOD5), water pH, and water salinity. There were 34 species of phytoplankton found in this study. The most predominant phytoplankton species in each beach were Navicula sp at Mertasari, Nitzschia sp at Sindhu, Pseudo-nitzschia sp at Purnama, Chaetoceros sp at Kethewel. Observation on macro algae showed that Ulva sp was to be the most predominant species in Serangan, Mertasari, and Sindhu beach (17.95, 16.25, and 17.81%). In mollusk observation, gastropod groups showed to be higher number than bivalve group. Nassarius sp showed to be the most predominant in Serangan beach (13.33%), while Ruditapes sp was predominant in Mertasari and Sindhu beach (11.59% and 14.81%). The highest diversity index of phytoplankton was shown by Kethewel beach (H = 1.35), while the lowest was shown by Shindu beach (H = 0.95). The highest diversity index of macroalgae was shown by Serangan beach which showed H = 2.08, while the lowest was shown by Purnama beach which showed H = 0.69. Serangan beach showed the highest diversity index (H = 2.72) with E = 0.66 compared to another locations, while Kethewel beach showed the lowest diversity index (H = 0.69 and E = 1). There was a relation between the existences of gastropod as the highest number of mollusk and Ulva sp as the gastropod feed

The Worship of Goddess Kotravai in Silappathikaram and the Life of the Eyinars

Kotravai worship is the most important place in the worship of the mother goddess of the ancient Tamils. Kotravai is an ancient goddess. In Sangam literature, Kotravai is referred to by the names Pazhayol, Ganamar Selvi, and Ayirai. Literature indicates that the Eyinars worshipped the Goddess Kotravai. Ilangovadigal in the Madurai chapter has explained in detail the worship of the Kortavai of the Eyinars in the Vettuvavari story. The Eyinars have lived as an ethnic group. The leadership was not mentioned to them. The Eyinars lived as ethnic groups and made their living under the rule of chieftains. It is a fact that the literature suggests the truth that people who were good at hunting in the early times may have turned into murderers and robbers due to poverty. But it is an incontrovertible fact that the Tamil people who lived in ancient times were Eyinars. It can be seen from the Silappathikaram that they have destroyed their own race by sacrificing to the Kotravai
