This research aims to determine the concentration of TSS distribution water quality characteristics and map the distribution of TSS in the waters of Nambo Beach. Determination of research stations used a purposive sampling method consisting of 7 stations. Water samples were taken at high tide and low tide using sample bottles. The method used in this research is a quantitative method and laboratory analysis to determine the TSS value. The method used to analyze TSS samples is the gravimetric method. The research results show that the distribution of TSS at high tide ranges between 21.80-122.00 mg/L, with the highest TSS value at stations 1-2, while the lowest value is at station 4, namely 21.80 mg/L. The TSS value at low tide ranges from 13.20-19.90 mg/L

A study was conducted on the distribution of heavy metals in sediments in Nambo Beach, Southeast Sulawesi Province, on July 24, 2022. This study aims to determine the content of heavy metals such as Cu, Pb, and Cd in sediments, determine the size of sediment grains, and assess the level of pollution in sediments on Nambo Beach. Determination of station points using a purposive sampling method with 7 station points. The technique used for heavy metal analysis in sediments is the atomic absorption spectrophotometry (AAS) method. The size of sediment grains is determined using a rock comparator, while to determine the level of pollution, the Geoaccumulation Index (I_Geo), Contamination Factor (CF), and Pollution Load Index (PLI) methods are used. The results of the study obtained showed that the highest content of heavy metals was Cu at all stations with values ranging from 0,011-0,0224 mg/L with an average value of 0,014 mg/L and the highest value was at station 1, Pb Metals, with values ranging from 0,001-0,0106 mg/L with an average value of 0,0033 mg/L and Cd with a relay range of 0,001-0,0025 mg/L and an average value of 0,0017 mg/L. The sedimentary grain sizes scattered on Nambo Beach include silt, clay, fine sand, and very fine sand. For testing the level of heavy metal pollution of Cu, Pb, and Cd in sediments, the results of calculations with the category of unpolluted to lightly polluted for all stations were obtained

Research on tidal analysis based on seasons has been carried out in Lasolo Bay, Southeast Sulawesi, using secondary data, namely tidal data in 2021 in January representing the western season, April representing the transition season I, July representing the eastern season and October representing the transition season II. This study aims to determine the type of tides formed and the value of sea level elevation in each season at the research site. Tidal data processing uses the admiralty method, producing amplitudes and phase differences from 9 main harmonic components. The analysis results of the calculation of formzhal numbers show that the type of tides formed in Lasolo Bay is a mixed type of double daily inclined with a formzhal number value of 0.5618-0.7059. In addition, based on the calculation of sea level elevation, the maximum average sea level (MSL) occurs in the second transition season (October), which is 532 cm, and the western season (January) is 460 cm. For the other two seasons, the first transitional season (April) and the eastern season (July) have an average sea level of 101 cm and 130 cm

Disaster management practices are very important in Waworaha Village which is geographically prone to disasters. This service is in the form of assistance for participatory disaster management practices in Waworaha Village which is intended to organize and provide disaster-prone information services, especially related to the preparation of disaster risk assessments, as well as community-based disaster-prone information communication and education in the village and organize and provide disaster prevention and preparedness service activities. Based on the history of disaster events, natural disasters that occur in Waworaha Village are earthquakes. The earthquake disaster risk of Waworah Village is included in the low and medium categories. As a form of prevention and preparedness, a disaster risk reduction forum and local training activities were established. This has made Waworaha Village a disaster resilient village.
