The dominant index (C) was 0.38 and the diversity index (H) was 1.65. The resident species were 120 individuals varying from 2 to 70 ind., and the most abundant was Neovespicula depressifrons (70 ind.). The dominant index (C) was 0.37 and the diversity index was 1.47.

The Content of Heavy Metals (Lead, Cadmium, and Mercury) in Gastropods Cellana Testudinaria and C. Radiata Attained in the Reclamation Coastal Waters of Manado Bay

Objective: Coastal waters are a repository for various potential wastes from various human activities both on land and at sea so that these ecosystems can be used as indicators in monitoring and evaluating the condition of natural resources and the environment.
 
 Method: The samples were kept in the coolbox and transferred to the Laboratory of the Fish Quarantine Center for Quality Control and Safety of Fishery Products (BKIPM) Bitung. The heavy metals analysis was also performed in this Laboratory.
 
 Results: The results of the analysis of heavy metals Mercury (Hg) showed that C. testudinaria shellfish had higher levels of mercury (Hg) (1.01 mg/g) compared to C. radiatashells (0.83 mg/g). The content of these heavy metals was below the threshold limits determined by BSN (2016). Thus the Gastropod shells of the types C. testudinaria and C. radiata are safe for application to food and non-food products. The low content of heavy metals in C. testudinaria and C. radiataindicates that Manado Bay waters are safe and not polluted by heavy metals.
 
 Conclusions: On the basis of all results, it can be concluded that the gastropod shellfish types Cellana testudinaria and C. radiata obtained values for lead (Pb) of 0.53 mg/g and 0.37 mg/g, cadmium (Cd) with values of 2.30 mg/g and 2.00 mg/g, and mercury (Hg) is 1.01 mg/g, and 0.83 mg/g. The content of these heavy metals is still below the threshold set by the government, so it is safe to be applied to food and non-food products.

Bird composition as an environmental quality indicator in Wallacea’s urban area

North Sulawesi Province, part of Wallace Bioregion, has a complex ecosystem. Advanced urban development brings various impacts, such as environmental change. Birds’ existence around human provides some advantages, such as assisting the process of plant pollination, controlling insect populations, and indicators of environmental quality. This study aimed to determine the bird species composition in four locations and the environmental quality was analysed using the Bird Community Index (BCI). This study gathered data on bird species in Manado Bay, Gunung Tumpa, Kawanua Arboretum, and the Kaki Dian areas. We conducted field observation through point count method as primary data and the secondary data were obtained from previous publications. Data were analyzed using Bird Community and Sorenson indexes. This study revealed that the birds’ quantities and composition moderately varied in four locations. This study found 37 bird species in Manado Bay, 33 in Tumpa Mountain, 36 in Kawanua Arboretum, and 49 in the Klabat mountain areas. The Bird Community Index (BCI) accumulation ranged from 56.0 – 68.4 and it was categorized as medium environmental quality. Sorensen’s community similarity index displayed a value of 30.3-51.0% which classified as low to medium community similarity.

Current condition of shallow-water benthic foraminifera in Manado bay, Indonesia

Coral reef community in Manado Bay is under pressure due to human activities in areas in and around Manado. In order to be able to wisely manage the bay area and the coral reefs in it, information about present conditions is needed. The use of marine organisms as bioindicators is one way to find information about the condition, and organisms such as foraminifera have the potential to be used as some species share the same requirement for water quality as the corals. Sampling for the foraminifera was carried out at 10 locations, and the depth of water ranged from 2.5 m to 7.0 m. The samples obtained were washed through a 63 μm sieve and dried. The separation of foraminifera tests from other sediments was done under a stereomicroscope and they were then identified to genus level. A total of 40 genera was identified among 3194 specimens. To get the FoRAM Index value, the foraminifera was categorized into three functional groups. 8 genera were categorized as symbiont-bearing group, 8 as opportunistic group, and 29 as heterotrophic group. FoRAM Index was found to be varied from 2.06 to 9.19 which indicated that Manado Bay water condition is also varied among the sampling area. In general based on the data obtained, it is assumed that water in Manado Bay is conducive for coral reef growth.

Analysis of Sea Surface Dynamics during the Coastal Floods in Manado

Coastal flooding is one of the serious problems facing most coastal areas in the world. On January 17 and December 7, 2021, coastal flooding hit the coastal area of Manado, North Sulawesi, Indonesia. The disaster disrupted economic activities on the coast of Manado Bay. This study analyzed the dynamics of the atmosphere and the sea during coastal flood events using water level data from the Geospatial Information Agency, which was then filtered to separate residual and atmospheric tide, and oceanographic reanalysis data of Wavewatch-III from BMKG Ocean Forecast System (OFS). The results show that events on January 17 and December 7, 2021, coincided with the occurrence of the maximum tide. The residual water level shows a significant value of around 0.2 – 0.3 m, indicating the influence of atmospheric phenomena on sea level rise. According to oceanographical data, the local wind is the main factor of flood occurrence, which is shown by wind speed data which increased wave height significantly to 1,5 m on January 17, 2021, and to 2,0 m on December 7, 2021, around Manado Bay coast. Another factor that might contribute to the event is Manado's land morphology. Further study must be conducted to discover the influence of land morphology on coastal floods.

Strategic action for waste management in Manado City to prevent marine debris input to Manado Bay: a preliminary study

Marine debris has become a serious threat for the coastal and marine environment. Their presence can degrade the quality of marine environments and also has negative impact on several aspects of people lives especially public health and aesthetics. Several efforts have been made, both short (to mitigate the impacts) and long terms (to manage them properly) efforts. Strategic action in waste management is very important in order to manage marine debris in Manado City; this is the objective of the research. In order to achieve the objective, several aspects on situation and condition of marine debris in Manado Bay has been described, and this include composition and density of debris at the coastal area, the quantity of the debris, waste management on land, the status of public awareness, the impact and degradation of marine debris in nature, institutional regulation, and waste management and planning. These aspects were analyzed to identify strengths and weaknesses before strategic actions for management are developed. The results showed that the composition, density, and quantity of marine debris in Manado Bay increased from 2017 to 2019. Waste management on land has been going well, the government institutions dealing with waste have been adequately arranged. Five strategic actions for waste management in Manado City to prevent the input of the waste to Manado Bay are proposed, they are: a) encouraging people to reduce the use of plastic-based products; b) involving people and community institution in waste management on land; c) increasing the activities of the community and community institution in keeping the environment (river, beach) clean; d) inviting the community and community institutions in working together to develop action programs which will be implemented jointly; and e) improvising the waste management according to existing regulations which include marine debris in specific management target and also incorporating rivers and other areas in waste management according to regulation.

Challenges in waste management at the household level in settlements along the Sario River as the source of marine debris to Manado Bay, Indonesia

Marine debris mitigation should be conducted thoroughly especially in the level where they are originated, which is household and settlement areas. In developing countries, waste management in household level has been a challenge because it has never been done properly. This study aims to evaluate the content and the application of waste management guidelines in settlement areas along the river, to assess the level of understanding of each head of family in using the guidelines and to assess the awareness level in doing the waste management. There are two aspects of waste management in household level: 1) waste management mechanisms, and 2) awareness of each head of family in was management. Mechanism aspect of waste management consists of two components. They are (1) guidelines in management mechanisms (which consists of guideline content and level of understanding-compliance) and (2) implementation of management mechanisms. Awareness aspect of each head of family in conducting waste management were assessed based on three components, they are 1) knowledge, 2) concern, and 3) willingness. A number of 249 households (from a total 453 who live in both sides of the river) were interviewed (as respondents) and they were chosen randomly. The respondent was those with family (parents and children) and the head of the household. The interview was conducted using a questionnaire, which content several questions related to the assessed aspects. The data was quantitatively analysed using a simple Statistics obtain percentages. The result shows that the a detailed content of guidelines on how to properly manage the was not found, the level of understanding on waste management was still low, the implementation of waste management in the level of household has not been done properly, and the willingness to share the finance in waste management is also low. It is then concluded that waste management at the household level in the regions faces various challenges. The best choice in waste management aspect at the household level is given in in this paper.

Comparison of Catch and Fish Interest in Surface LED Lights and Underwater LED Lights at FADs around Rafts in Manado Bay

Manado Bay waters is one of the water areas in North Sulawesi that has potential fishery resources, with fishing efforts using rafts mounted on surface electric lights. For high FAD usefulness, the light used must be able to collect fish that are at great distances both horizontally and vertically. The purpose of this study was to obtain the composition of the fish caught and how much the fish was determined to be when the raft was without lights in the water and when the raft was equipped with lights in the water. The method used was an experiment using 2 (two) types of lights, namely electric surface lights and LED lights in water, and 3 (three) types of fishing gear, namely fishing rods, ring seines and nets). The types of fish caught were dominated by selar fish (Selaroides sp), moonfish (Lampris guttaus), Trevally fish (Caranx sp) and squid (Loligo sp). The fish's interest in the light was observed since the first 15 minutes the lights were turned on, and were around 4 to 6 meters and the longer they were getting closer to the lights for about 1 hour the fish would cluster around the raft for about 2-4 meters.Keywords: FAD, Underwater lamp, Manado Bay.AbstrakPerairan Teluk Manado merupakan salah satu kawasan perairan di Sulawesi Utara yang memiliki sumberdaya perikanan yang potensial, dengan usaha penangkapan ikan dengan alat bantu rakit yang dipasang lampu listrik permukaan.

The form and distribution of microplastic in sediment and water columns of Manado Bay, North Sulawesi

Microplastics are particles measuring <5mm that is the result of degradation from plastic waste that enters the environment. Plastic waste is degraded into microplastics through physical, chemical, and biological processes. Pollutants such as microplastics that enter the waters of Manado Bay can reduce the biological and ecological functions of the ecosystem in the waters. The purpose of this study was to determine the shape and density of microplastics in Manado Bay. The sediment sampling method was carried out by purposive sampling method and for the water, column using a plankton net withdrawal method of 10 meters with 3 replications at 3 stations. The sample will be prepared and then identified. Then the sample density was calculated and then analyzed using a one-way ANOVA test and Pearson correlation.

Fate of internal solitary wave and enhanced mixing in Manado Bay, North Sulawesi, Indonesia

The Sulawesi Sea is one of the most active regions where internal solitary waves (ISWs) are frequently observed through satellite images. These waves that result from the nonlinear evolution of internal tides are generated over the Sibutu Sills and propagate over a long distance, up to 700 km before shoaling in coastal areas. To date there is yet no specific in-situ observation or numerical studies dedicated to characterize their dynamics. We present results from the combination of two simulations and in-situ observations which allow to describe the full life cycle from generation to breaking of ISWs in the Sulawesi Sea. A first set of 2D non-hydrostatic numerical simulations reproduces the generation of ISW from the non-linear steepening of the internal tides. The tidal energy flux emanated from the generation site is of about 15 kW m−1 with progressive decrease in the along flux direction resulting the growth of ISWs. The ISW energy flux increases up to large fraction of 32% of the total energy flux at 700 km from the generation point while the M2 internal tide contributes to 64% of the total energy flux. A second simulation at higher resolution focusing on the shallow coastal area of the Manado Bay reproduces the breaking of the ISWs at the shelf slope and was compared with in-situ observations. About 3.5% of the energy contained in an ISWs packet is dissipated over a 3 km wide cross shelf region of the Manado Bay in the simulation. Both simulations and observations revealed the presence of energetic boluses identified as a sequence of high-frequency waves of elevations in the stratified bottom layer. A high level of turbulence was diagnosed in the observations and simulations from the Thorpe Method. The mean eddy kinetic energy dissipation rate and vertical diffusivity in the observation reaches as 10−6 W kg−1 and 10−3 m2 s−1, respectively; while the dissipation rate is one order of magnitude higher and the vertical diffusivity is one order lower in the model. This discrepancy likely reflects the sparse sampling in the observations as well as differences in the stratification and the absence of surface forcing in the model.

Kajian waktu penangkapan ikan Kurisi Bali (Etilis sp) dengan pancing ulur di perairan teluk Manado

Demersal fish species, such as Red snappers (Etelis sp.), have high economic value and are in high demand in both domestic and export markets. The fishing gear used by fishermen in the Manado Bay waters to catch demersal fish, especially Red snappers, is the bottom hand line. The lack of complete information about the distribution of the Red snappers in their habitat, the size of the fish and the fishing time and techniques are the main problems.This study is aimed at providing the legal size, fishing technique, and fishing season in relation with feeding period, bait type, and correct fishing grounds for red snapper Etelis sp.. The study utilized explorative method through direct observations and interviews. During the study, 986 individuals of red snappers were caught, 517 individuals in morning operation and 469 in afternoon operation. On monthly basis, there were 270 fish caught in July, 165 fish in February, 154 fish in January and the rest was distributed in other months. Red snappers Etelis sp. were caught mostly at 04:30-05:00 in the morning and 17:01-17:30 in the afternoon. The fish catches consisted of size range of >620 mm TL (110 ind), 630-700 mm TL (452 ind), 710-760 mm TL (333 ind), and 770-800 mm TL (91 ind).

Variations of Marine Debris In Manado Bay and its environs

Nowadays, Indonesia is facing an increasing crisis of debris pollution. Through rivers, city drainage, marine activities, and tourists, garbage can enter the sea. The existence of this debris is a new threat that has a terrible impact on the marine ecosystem and the socio-economic sustainability of the community. Based on this, the Government of Indonesia has issued a regulation in Presidential Regulation no. 83 of 2018 concerning Marine Debris Management. One of the achievement points is the compilation of baseline data and publication of marine debris in all coastal areas of Indonesia every year. This study aimed to identify the types of marine debris found in macro and meso sizes and to analyze the composition and density of marine debris on the coast of Manado Bay and its environs during ebb and flood tide. Sampling was carried out on five beaches in Manado Bay and its environs using the Marine Debris Monitoring Guidelines by the Ministry of Environment and Forestry (KLHK) 2020. Based on the data collection, it was found that nine types of marine waste materials and types of plastic waste were the most dominant types of waste found (about 70-86%). Of the five research sites, Sindulang Beach is the location with the highest solid waste density of 8.28 items/m2 (during flood tide) and 15.31 items/m2 (during ebb tide). Overall, the amount of marine debris found during ebb tide conditions was more than during flood tide conditions, and the amount of macro-sized trash was more than meso-size. White and transparent colors were the dominant color.Keywords: Composition; Density; Macro and Meso-Marine debris; Manado Bay; Color of debrisAbstrakSaat ini Indonesia sedang menghadapi krisis pencemaran sampah yang kian meningkat Sampah dapat masuk ke laut melalui aliran sungai, drainase kota, aktivitas laut maupun dari para wisatawan Keberadaan sampah tersebut menjadi ancaman baru yang sangat berdampak buruk terhadap ekosistem laut dan keberlangsungan sosial ekonomi masyarakat.
