Study of Chlorophyl-A Variability in Bone Bay Waters During High Wave Events

Research has been carried out on the distribution of chlorophyll-a in the waters of Bone Bay during high wave events based on the parameters of sea surface temperature, wind speed and ocean currents. The aim of this research is to analyze parameters related to high waves which influence chlorophyll-a concentrations in the waters of Bone Bay. Chlorophyll-a patterns in Bone Bay waters were studied based on Aqua MODIS satellite data for chlorophyll-a data and ECMWF for wind speed, sea surface temperature and ocean current data. The average value was determined using Aqua MODIS and ECMWF satellite data for 10 years from 2011 to 2020. These parameters were analyzed to determine the correlation with chlorophyll-a. The calculation results show that sea surface temperature and wind speed decreased after high waves, while ocean currents and chlorophyll-a increased after high waves in Bone Bay waters. The correlation between chlorophyll-a and wind speed is 0.15, with sea surface temperature -0.44, and with ocean currents -0.26. Spatially, high concentrations of chlorophyll-a are found in the coastal waters of the South Sulawesi region with chlorophyll-a concentrations reaching 0.4-5 mg/m3. Temporally, high chlorophyll-a concentrations occur after high wave events with an average chlorophyll-a concentration of 0.32 mg/m3.

Beach Cleaning Action Movement as an Effort to Create Environmentally Friendly Tourism on Kapu Beach, Kolaka Regency

Kolaka is one of the districts in Southeast Sulawesi. Kolaka Regency is a coastal area located in Southeast Sulawesi Province. Kolaka is like a hidden paradise on the west coast of Sulawesi Island. As a large area that borders the sea, namely Bone Bay to the west. Kolaka Regency has a coastline that stretches for 293.45 km, decorated with white sandy beaches, clear sea water. One potential that is worth paying attention to as a tourist destination is Kapu Beach, which is located in Kapu Village, Samaturu District, Kolaka Regency. However, currently, Kapu Beach is polluted with lots of plastic and organic waste scattered around and reducing the beauty of the beach. The method used in this activity is the observation method. The first stage that was carried out began with coordination with the local government and the management of Kapu Beach. The second stage, namely checking the condition of the tourist beaches that would be cleaned, as well as preparing paint for re-tightening the trees and aesthetic photo spots. The third stage, This stage carries out the process of cleaning the beach tourism environment and painting several photo spots. What is meant by the observation method is a way of collecting information from relevant data by observing. The result of this activity for the surrounding community is to build self-awareness for the community to care about the beach and coastal environment and also be aware of the dangers of environmental pollution, considering that the location where they live is on the coast of Kapu Village. Based on the results of the service carried out, the conclusion that can be drawn from the beach clean-up activity is that it was held smoothly and in accordance with the previously planned activity structure, and cleaning up rubbish at the tourist attraction was not easy, the large number of visitors not only had a positive impact on tourist attractions but there There is also a negative impact, namely, where a lot of plastic waste is found both around the gazebo and even on the coast, there is also a lot of waste used from visitors' food. It is important to maintain the cleanliness of the beach tourism environment so that it can be managed well and optimally.

Influence of Marine Heatwaves on Upwelling Parameter in Indonesian Fisheries Management Area (IFMA) 713 Waters

Abstract An upwelling process linked to water productivity is likely to be affected by marine heatwaves (MHWs). The events of MHWs are distinguished by warmer sea surface temperature (SST), leading to increased stratification, causing vertical mixing limits and suppressing the upwelling process. In the Indonesian Fisheries Management Area (IFMA) 713 waters, which have enormous potential for fishery resources, five upwelling areas were identified during the southeast monsoon months (May–October) based on the Ekman pumping velocity (EPV) assessment, namely locations A (western part of West Sulawesi), B (southern Makassar), C (eastern part of Bone Bay), D (southern Banjarmasin), and E (southern Makassar Strait). Thus, this study aimed to investigate the influence of MHWs on upwelling parameter (chlorophyll-a concentration) in IFMA 713, particularly in 1998 and 2016, where prominent MHWs occurred and coincided with upwelling sessions. To accomplish this, EPV anomalies and chlorophyll-a concentrations for each MHWs event during May–October 1998 and 2016 were calculated. The analysis revealed that MHWs events co-occuring with negative (upwelling velocity is weaker than the climatological mean) and positive (upwelling velocity is stronger than the climatological average) EPV anomalies were associated with decreased chlorophyll-a concentrations.

Genetic Diversity of Flying Fish (Exocoetidae) in Southeast Sulawesi, Indonesia

Flying fish (Exocoetidae) is a pelagic fishery commodity that holds economic value among the people of eastern Indonesia. Flying fish are advantageous as they are abundant in Indonesian sea waters, making them an affordable source of omega-3, which is beneficial for human health. However, the high demand for flying fish has resulted in overfishing, which poses a risk of reducing their natural population. Proper management of this commodity is necessary to minimize these risks. Effective management requires adequate information, including genetic diversity data. This study aims to determine the genetic diversity of flying fish in Southeast Sulawesi, specifically in the Banda Sea and Bone Bay populations. Tissue samples were collected from flying fish in the two populations during the study in March 2022. The results show that the genetic diversity values of flying fish in Bone Bay and the Banda Sea were 0.984 and 1.00, respectively, while the nucleotide diversity values were 0.021 and 0.018. High genetic diversity values and nucleotide diversity values were found between the two populations, with values of 0.990 and 0.020, respectively. Based on phylogenetic analysis, the two populations in Southeast Sulawesi are genetically similar.

Abstract. Tambaru R, Burhanuddin AI, Haris A, Amran MA, Massinai A, Muhiddin AH, Yaqin K, Firman, Yuliana. 2024. Diversity and abundance of phytoplankton in Bone Bay, South Sulawesi, Indonesia and its relationship with environmental variables. Biodiversitas 25: 624-631. Ecological studies of phytoplankton have been widely conducted in various bays around the world. However, such research is still limited in Bone Bay, South Sulawesi, Indonesia. Therefore, this study aimed to investigate the diversity and abundance of phytoplankton in Bone Bay and the relationships with environmental factors. Data collection was conducted in the dry season (May to June 2023) at four stations, namely Bajoe Harbor (PB), Cappa Ujung (CU), Libureng (LB), and Tongke-Tongke (TT). At each station, seawater samples were collected and environmental variables were measured including temperature, salinity, pH, currents, and nutrients (i.e. Nitrate, Nitrite, Ammonium, Orthophosphate, and Silicate). In general, the environmental variables in the studied area were within the range of optimal condition for phytoplankton to grow and develop. There were three classes of phytoplankton recorded, namely Bacillariophyceae, Cyanophyceae, and Dinophyceae, with a total of 31 genera were identified. Chaetoceros, Thallasionema, and Rhizosolenia were the dominant genera. The average abundance of phytoplankton was significantly different among stations with the highest was found in CU and PB compared to that in LB and TT (p-value <0.01). PCA analysis showed that phytoplankton abundance was related to high orthophosphate concentrations, silicate, and turbidity at the PB and CU stations, while the opposite condition occured at the LB and TT stations. Based on the diversity and abundance of phytoplankton, Bone Bay, South Sulawesi is now still in good condition, yet monitoring studies are recommended to see the changes in the future.

Economic and Marketing Study of Purse Seine Catch Results in Bone Bay Waters, Bone Regency

Harvesting marine biological resources especially fish, is still largely dotted with fishing activities. One of the fishing businesses engaged in fishing that has already developed in Indonesia, especially in the South Sulawesi Bone Bay is a ring trawl business (Purse seine). The magnitude of the potential of fisheries in the bone bay led to the formation of a large number of purse seine fishing business units in Bone district. However, erratic natural conditions make production yields non-permanent so it is necessary to know how much this business is still feasible to continue. In this purse seine catch production flow, aspects of marketing and distribution anaises are an important part of knowing the effectiveness of production to support the economy of society. The research was conducted from October to November 2020. In this study the income received by the purse seine capture business unit in bone bay was 1,115,964,357.52/year and indicated that the purse seine business carried out by the fishing business actor was feasible to develop by the division between receipts and costs has a value of more than one (>1). Based on the Marketing aspect the value of marketing efficiency of purse seine catches is set according to the marketing channel value <1 which means it can be said that both channels are efficient marketing on each fish commodity.

Analysis of Response and Performance of Bugis-Makassar Stilt House Structures Using Pushover Analysis

South Sulawesi is one of the areas prone to earthquakes. The Walanae Fault extends from the Makassar Strait to the Bone Bay. This fault stretches along the Walanae River and passes through the districts of Pinrang, Sidrap, Bone, to the Gulf of Bone. The structure of the stilt house is one that is earthquake resistant because it does not directly receive earthquake energy. Traditional techniques on the structure of houses on stilts in Bima district for earthquake resistance researched by Agus Hariyanto, Sugeng Tiyadi, and Andy Widyowijatnoko, stated that the local structural technique, namely pa’a which was empirically developed by the community over the years can reduce the vulnerability of houses. against earthquakes. This technique turns out to have similarities with the framework of the Bugis-Makassar stilt structure, which is classified as a rigid joint truss system. The purpose of this study was to determine the response and performance of the Bugis-Makassar stilt house structure in the Bone region which represents a high level of earthquake risk. The analysis was carried out on the structure of a Bugis stilt house in Bone using the ETABS v.20 program to obtain the response and performance of the structure. The results of the structural response from the study indicate the value of the lateral deviation of the floor. The Bone region has a floor lateral deviation of 3.64 mm and 6.45 mm for the X and Y directions. Based on the pushover analysis, the structure performance level has a B performance level for the Bone Region.
