Abstract

Microalgae are organisms that contain chlorophyll and other pigments so they can carry out photosynthesis. Microalgae are widespread in nature and can be found in any environment exposed to sunlight. Microalgae are micro-sized biota with a diameter of less than 2 µm. The benefits of microalgae for other living things, especially humans, are numerous, including as a source of food and ingredients in the manufacture of medicines. Dunaliella sp. is a group of green algae that contains protein, fat and carbohydrates as a good source of food. Growth rate and density of microalgae Dunaliella sp. and the effect of lead acetate with different concentrations was observed using a microscope, starting from the lag phase, the logarithmic phase, the stationary phase and the declination phase. Dunaliella sp. Experiencing an exponential phase in the observation before treatment, namely on the 9th day and then doing the treatment. Treatment with lead acetate with concentrations of 10 ppm, 50 ppm and 80 ppm is very influential in the growth of microalgae. The result is that lead acetate contains toxins that can kill microalgae cells in both low and high concentrations.Keywords: Microalgae, Dunaliella sp., Lead Acetate, Concentration

Abstract

Kappaphycus alvarezii is one species algae that is very widely developed in the tropical waters, especially in Indonesia. The potential in these waters may decrease due to heavy metal pollution that accumulates in algae and sediments. Analyzing the content of heavy metal arsenic (As), using the SNI 01-2896-1998 test method, namely the metal contamination test method in food. The results obtained from this study were samples of brown and green Kapapphycus alvarezii taken from week I-V detected containing heavy metal arsenic (As) ranging from 0.17 - 0.42 ppm for green algae and 0.12 - 0.37 ppm for brown algae. This As concentration does not exceed the maximum heavy metal limit, which is 1.0 ppm for the maximum limit for heavy metal contamination in food. The concentration of heavy metal in sediments is 1.12 ppm, not exceeding the quality standard in the Environmental Protection Agency (EPA), the maximum heavy metal limit for arsenic in sediment is below 10 mg/kg

Abstract

Based on the material content, waste is grouped into two types, namely organic waste (waste derived from animal, plant and human parts) and inorganic waste (waste derived from materials such as metal, glass, styrofoam, plastic and rubber). Inorganic waste is one of the coastal pollution problems, yet information about inorganic waste in mangrove ecosystem was relatively low, especially at Lesah Village, Tagulandang Sub district, Sitaro Regency. This study aims to determine the distribution of inorganic waste by type and to analyze the characteristic of inorganic waste based on the amount of size and weight found. The method used in this research is the line transects method at 3 different stations. The results showed that the types of marine debris that found were plastic, rubber, metal, and glass waste and there were 2 characteristics, namely mega-debris and macro-debris. Of the various types of debris obtained, plastic is the most commonly found, 161 items/23.329m2 (69.099 Items/ha) with a total weight of 1357.75 gram/ha and a total size of 1938.93 cm/ha. Followed by rubber debris as many as 5 items/23.329m2 (2.146 items/ha) with a total weight of 159.309 gram/ha and a total size of 59.871 cm/ha. Then, glass debris as many as 4 items/23.329m2 (1.717 items/ha) with a total weight of 402,159 grams/ha a total size of 31.030 cm/ha. Whereas, metal debris is the lowest value found as many as 3 item/23.329m2 (1.288 items/ha) with a total weight of 67.622 gram/ha and a total size of 19.528 cm/ha.Keywords: Inorganic waste, Mangrove Ecosystem, Desa Lesah

Abstract

Molluscs are marine organisms that do not have a backbone, these organisms are associated with coral reefs. This research was conducted with the aim of describing the density and diversity of Prosobranchia snails’ species on coral reef flats. By applying the belt transect method, the results show that the density of the four Mokupa stations has a relatively high density between Tongkeina, Malalayang and Bulo. While for species diversity, Mokupa and Bulo had the highest value than Tongkeina and Malalayang. According to the results of the belt transect method, is the concluded that stations close to people’s homes have the lowest density and species diversity values, this factor is influenced by anthropogenic activities or human activities. Therefore, it is recommended that there be monitoring of snails on coral reefs, especially reef flattening in order to provide information about Prosobranchia snails.Keywords: Prosobranchia, Density, diversity, belt transects, Reef Flats

Abstract

The waters surrounding the Minahasa Peninsula are important areas of various activities by use of coastal and marine space. This research aims, firstly to describe direction, period and height of waves at several water areas around the Minahasa Peninsula in various season. Secondly to analyze the characteristic of daily and seasonal waves. The wave parameter, which reanalysis by ECMWF for 5 years (September 2014 to august 2019) were used in this research.  By the analysis spasial-temporal, the results are presented by the rose grapich waves direction and stock chart. The wave propagation in the north season and transition season I, is dominated by the northeasterly wave. While the wave propagation in the southern season and the transitional season II, is more diverse directions. The characteristics of the waves formed in the southeast Minahasa waters in the north season and transitional season I, show that the wave period is greater than in the waters of Manado Bay and Bitung waters. Furthermore, the wave characteristics formed in the waters of the Minahasa Peninsula show a significant wave height in Bitung waters which is higher than the waters of Manado Bay and Southeast Minahasa waters.Keywords: Waves, ECMWF, Minahasa Peninsula Waters Perairan sekitar Semenanjung Minahasa merupakan kawasan penting dalam berbagai aktivitas pemanfaatan ruang pantai dan laut.
