Abstract: - The pollution of Plumbum heavy metal in water is an environmental concern. Plumbum (Pb) can be

found in water naturally and due to human activities. This study aimed to analyze Plumbum heavy metal's

content in the waters of Batu Jaya village in Southeast Sulawesi. The research method employed was

descriptive, and the samples were tested for Plumbum heavy metal content using Atomic Absorption

Spectrophotometer. The study revealed that several stations (ST) exceeded the threshold, including ST 2 with

0.0217 mg/l, ST 3 with 0.0220 mg/l, ST 5 with 0.0182 mg/l, ST 6 with 0.0141 mg/l, and ST 10 with 0.0312

mg/l. On the other hand, other stations, namely ST 1, 4, 7, 8, and 9, remained within acceptable limits.

Consequently, Plumbum heavy metal is present in the waters of Batu Jaya village, South Konawe Regency,

Southeast Sulawesi Province, Indonesia. The pollution originates from human activities in the vicinity of the

port and from ship traffic passing through the area.

Indonesia is an archipelagic country with two-thirds

of the ocean area more significant than the land

area, placing Indonesia in second place after Canada

as a country with the longest coastline in the world.

Southeast Sulawesi is one of the provinces in

eastern Indonesia, which consists of several small

islands and coastal regions that dominate the area.

This area is very vulnerable to pollution and

environmental pressure, which the primary source

example, in several areas of China's sea, a study

conducted in 3 seasons finds heavy metal

of the marine ecosystem, [6]. It's important to be

aware of the amount of iron you're consuming, as

too much of this essential element can have toxic

tourism, agriculture, etc., cause heavy metals getting

into the waters. When heavy metals enter the waters,

region, which has immense potential for heavy

metal contamination, is Batu Jaya Village in South

Konawe Regency. From the initial survey, several

streams in crowded activity eventually flow into

these waters, which are suspected of distributing the

Plumbum heavy metal into these waters. This study

aims to determine Plumbum heavy metal pollution

in the seas of Batu Jaya village in Southeast

Sulawesi. Research on lead pollution in the

awareness efforts. This research is crucial for

promoting prevention measures, reducing lead

exposure, and safeguarding human health and

ecological sustainability. With this knowledge, we

can develop policies, regulations, and practices that

better protect the environment and human health

from the harmful effects of lead.

Indonesia. Determination of the sampling points

used a purposive sampling method accompanied by

a GPS (Global Positioning System) tool in

determining the coordinates of the location of

seawater sampling. This study is a descriptive study

to see the levels of Plumbum heavy metal in the

waters of Batu Jaya village. The location points of

the survey were concentrated at ten stations divided

The map of the sampling points is presented in

areas were not detected from the ten sampling

locations, such as at points 1,4, 7, 8, and 9. As for

points 2, 3, 5, 6, and 10, there were Plumbum heavy

metal contents, most of which passed the Threshold

Value according to the Ministry of Environment

Republic of Indonesia number 51 in 2004, where the

pollution level was high. An overview of seawater

quality in the chemical aspects found in the waters

of Batu Jaya Village, South Konawe Regency, in

2022 could be seen from the results of tests

conducted at the Southeast Sulawesi Provincial

high risk of contamination are points 2, 3, 5, 6, and

10. Thus 5 points contain undetected heavy metal

content, and 5 points of the location contain the

Plumbum heavy metal and exceeding the Threshold

Limit Values which had been set based on the

quality standards of seawater according to the

Decree of the Ministry of Environment number 51

of 2004 (Table 1).

pollution. Based on the analysis, the risk of lead

five points in the research location indicate high

contamination risk. These points are 2, 3, 5, 6, and

10. This shows that the lead levels in these points

exceed the established Threshold Value, indicating a

significant level of contamination. There are five

points in the research location with undetectable

lead levels or low contamination risk. The other five

points contain lead levels exceeding the Threshold

Value and indicate high contamination risk.

the body, will endanger people's health. Lead

release into the air originates from industrial

activities and vehicle exhaust emissions, leading to

environmental pollution. Consequently, lead (Pb)

can contaminate the soil and dissolve in water,

which plants can then absorb. As a result, humans

can be exposed to lead through food or drinking

water, [10]. Exposure to lead has negative impacts

inhibit rusting on metal or iron surfaces, [15]. The

study on the Sampur coast, Central Bangka district,

obtained similar results where the Plumbum heavy

metal content was high in concentrations in areas

where fishermen anchored their boats, [16].

Pollution can come from the process of washing and

maintaining ships, as well as the fuel used by ships

spilled, [15], [17]. Besides the fuel waste from

fishing boats, household waste also contributes to

high levels of heavy metals in this area, [18], [19].

human activities around the coastal tourism area

may trigger the presence of the Plumbum heavy

metal at the border of the two villages, [6], [20]. The

same results were also obtained in the study in the

Raja Ampat Tourism area of West Papua, where the

highest levels of Pb heavy metal were at points

located in tourist areas and ports, [21]. Sources of

heavy metals can come from ship fuel waste in the

form of oil, anti-rust paint materials from ship hulls,

and wood preservatives for ships made of wood,

limit. This is because the location of the four

stations is in an area close to the rocks. In addition,

there is rarely people activity in this area because it

is far from residential areas.

by lead can affect future generations. In addition,

aquatic ecosystems also suffer from excessive lead

content. Aquatic organisms such as phytoplankton,

algae, and invertebrates can be negatively affected

by lead. This can lead to population decline,

reproductive disorders, and even long-term

mortality. Lead can also disrupt the biogeochemical

cycle and damage water quality, thus impacting the
